influences.", "Toriyama stated he was influenced by animator Toyoo Ashida and the anime television series adaptation of his own ''Dragon Ball''; from which he learned that separating colors instead of blending them makes the art cleaner and coloring illustrations easier.It was Toriyama's sound effects in ''Mysterious Rain Jack'' that caught the eye of Kazuhiko Torishima, who explained that usually they are written in ''katakana'', but Toriyama used the Roman alphabet which he found refreshing.", "Torishima has stated that Toriyama aimed to be a gag manga artist because the competitions that he submitted to early on required entries in the gag category to only be 15 pages long, compared to story manga entries which had to be 31.In his opinion, Torishima stated that Toriyama excels in black and white, utilizing black areas, as a result of not having had the money to buy screentone when he started drawing manga.", "He also described Toriyama as a master of convenience and \"sloppy, but in a good way.\"", "For instance, in ''Dragon Ball'', destroying scenery in the environment and giving Super Saiyans blond hair were done in order to have less work in drawing and inking.", "Torishima

the classic Chinese novel ''Journey to the West'', with Goku being Sun Wukong and Bulma as Tang Sanzang.", "It was also inspired by Hong Kong martial arts films, particularly those of Jackie Chan, and was set in a fictional world based on Asia, taking inspiration from several Asian cultures including Japanese, Chinese, Indian, Central Asian, Arabic, and Indonesian cultures.", "Toriyama continued to use his characteristic comedic style in the beginning, but over the course of serialization this slowly changed, with him turning the series into a \"nearly-pure fighting manga\" later on.", "He did not plan out in advance what would happen in the series, instead choosing to draw as he went.", "This, coupled with him simply forgetting things he had already drawn, caused him to find himself in situations that he had to write himself out of.Toriyama was commissioned to illustrate the characters and monsters for the first ''Dragon Quest'' video game (1986) in order to separate it from other role-playing games of the time.", "He has since worked on every installment in the series.", "For each game Yuji Horii first sends rough sketches of the characters with their background information to Toriyama, who then re-draws them.", "Lastly, Horii approves the finished work.", "Toriyama explained in 1995 that for video games, because the sprites are so small, as long as they have a distinguishing feature so people can tell which character it is, he can make complex designs without concern of having to reproduce it like he usually would in manga.", "Besides the character and monster designs, Toriyama also does the games' packaging art and, for ''Dragon Quest VIII'', the boats and ships.", "In 2016, Toriyama revealed that because of the series' established time period and setting, his artistic options are limited, which makes every iteration harder to design for than the last.", "The series' Slime character, which has become a mascot for the franchise, is considered to be one of the most recognizable figures in gaming.Manga critic Jason Thompson declared Toriyama's art influential, saying that his \"extremely personal and recognizable style\" was a reason for ''Dragon Ball'''s popularity.", "He points out that the popular ''shōnen'' manga of the late 1980s and early 1990s had \"manly\" heroes, such as ''City Hunter'' and ''Fist of the North Star'', whereas ''Dragon Ball'' starred the cartoonish and small Goku, thus starting a trend that Thompson says continues to this day.", "Toriyama himself said he went against the normal convention that the strongest characters should be the largest in terms of physical size, designing many of the series' most powerful characters with small statures.", "Thompson concluded his analysis by saying that only Akira Toriyama drew like this at the time and that ''Dragon Ball'' is \"an action manga drawn by a gag manga artist.\"", "However, James S. Yadao, author of ''The Rough Guide to Manga'', points out that an art shift does occur in the series, as the characters gradually \"lose the rounded, innocent look that Toriyama established in ''Dr.", "Slump'' and gain sharper angles that leap off the page with their energy and intensity.\"" ], [ "Legacy and accolades", "Thompson stated in 2011 that \"''Dragon Ball'' is by far the most influential shonen manga of the last 30 years, and today, almost every ''Shōnen Jump'' artist lists it as one of their favorites and lifts from it in various ways.\"", "David Brothers of ComicsAlliance wrote that: \"Like Osamu Tezuka and Jack Kirby before him, Toriyama created a story with his own two hands that seeped deep into the hearts of his readers, creating a love for both the cast and the medium at the same time.\"", "In a rare 2013 interview, commenting on ''Dragon Ball''s global success, Toriyama admitted, \"Frankly, I don't quite understand why it happened.", "While the manga was being serialized, the only thing I wanted as I kept drawing was to make Japanese boys happy.\"", "He had previously stated in 2010, \"The truth is, I didn't like being a manga artist very much.", "It wasn't until relatively recently that I realized it's a wonderful job.\"", "Many artists have named Toriyama and ''Dragon Ball'' as influences, including ''One Piece'' author Eiichiro Oda, ''Naruto'' creator Masashi Kishimoto, ''Fairy Tail'' and ''Rave'' author Hiro Mashima, ''Boruto: Naruto Next Generations'' illustrator Mikio Ikemoto, ''Venus Versus Virus'' author Atsushi Suzumi, ''Bleach'' creator Tite Kubo, ''Black Cat'' author Kentaro Yabuki, and ''Mr.", "Fullswing'' author Shinya Suzuki.", "German comic book artist Hans Steinbach was strongly influenced by Toriyama, and Thai cartoonist Wisut Ponnimit cited Toriyama as one of his favorite cartoonists.", "Ian Jones-Quartey, a producer of the American animated series ''Steven Universe'', is a fan of both ''Dragon Ball'' and ''Dr.", "Slump'', and uses Toriyama's vehicle designs as reference for his own.", "He also stated that \"We're all big Toriyama fans on ''Steven Universe'', which kind of shows a bit.\"", "French director Pierre Perifel cited Toriyama and ''Dragon Ball'' as influences on his DreamWorks Animation film ''The Bad Guys''.In 2008, Oricon conducted a poll of people's favorite manga artists, with Toriyama coming in second, behind only ''Nana'' author Ai Yazawa.", "However, he was number one among male respondents and among those over 30 years of age.", "They held a poll on the Mangaka that Changed the History of Manga in 2010, ''mangaka'' being the Japanese word for a manga artist.", "Toriyama came in second, after only Osamu Tezuka, due to his works being highly influential and popular worldwide.", "Toriyama won the Special 40th Anniversary Festival Award at the 2013 Angoulême International Comics Festival, honoring his years in cartooning.", "He actually received the most votes for the festival's Grand Prix de la ville d'Angoulême award that year; however, the selection committee chose Willem as the recipient.", "In a 2014 NTT Docomo poll for the manga artist that best represents Japan, Toriyama came in third place.", "That same year, entomologist Enio B.

[ [ "Ariane 5" ], [ "Introduction", "'''Ariane 5''' is a retired European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA).", "It was launched from the Centre Spatial Guyanais (CSG) in French Guiana.", "It was used to deliver payloads into geostationary transfer orbit (GTO), low Earth orbit (LEO) or further into space.", "The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017.Since 2014, Ariane 6, a direct successor system, is in development.The system was designed as an expendable launch system by the ''Centre national d'études spatiales'' (CNES), the French government's space agency, in cooperation with various European partners.", "Despite not being a direct derivative of its predecessor launch vehicle program, it was classified as part of the Ariane rocket family.", "ArianeGroup was the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European contractors.", "Ariane 5 was originally intended to launch the Hermes spacecraft, and thus it was rated for human space launches.Since its first launch, Ariane 5 was refined in successive versions: \"G\", \"G+\", \"GS\", \"ECA\", and finally, \"ES\".", "The system had a commonly used dual-launch capability, where up to two large geostationary belt communication satellites can be mounted using a '''SYLDA''' (''Système de Lancement Double Ariane'', meaning \"Ariane Double-Launch System\") carrier system.", "Up to three, somewhat smaller, main satellites are possible depending on size using a '''SPELTRA''' (''Structure Porteuse Externe Lancement Triple Ariane'', which translates to \"Ariane Triple-Launch External Carrier Structure\").", "Up to eight secondary payloads, usually small experiment packages or minisatellites, could be carried with an '''ASAP''' (Ariane Structure for Auxiliary Payloads) platform.Following the launch of 15 August 2020, Arianespace signed the contracts for the last eight Ariane 5 launches, before it was succeeded by the new Ariane 6 launcher, according to Daniel Neuenschwander, director of space transportation at the ESA.", "Ariane 5 flew its final mission on 5 July 2023." ], [ "Vehicle description", "=== Cryogenic main stage ===Vulcain engineAriane 5's cryogenic H173 main stage (H158 for Ariane 5G, G+, and GS) was called the EPC (''Étage Principal Cryotechnique'' — Cryotechnic Main Stage).", "It consisted of a diameter by high tank with two compartments, one for liquid oxygen and one for liquid hydrogen, and a Vulcain 2 engine at the base with a vacuum thrust of .", "The H173 EPC weighed about , including of propellant.", "After the main cryogenic stage runs out of fuel, it re-entered the atmosphere for an ocean splashdown.=== Solid boosters ===Attached to the sides were two P241 (P238 for Ariane 5G and G+) solid rocket boosters (SRBs or EAPs from the French ''Étages d'Accélération à Poudre''), each weighing about full and delivering a thrust of about .", "They were fueled by a mix of ammonium perchlorate (68%) and aluminium fuel (18%) and HTPB (14%).", "They each burned for 130 seconds before being dropped into the ocean.", "The SRBs were usually allowed to sink to the bottom of the ocean, but, like the Space Shuttle Solid Rocket Boosters, they could be recovered with parachutes, and this was occasionally done for post-flight analysis.", "Unlike Space Shuttle SRBs, Ariane 5 boosters were not reused.", "The most recent attempt was for the first Ariane 5 ECA mission in 2009.One of the two boosters was successfully recovered and returned to the Guiana Space Center for analysis.", "Prior to that mission, the last such recovery and testing was done in 2003.The French M51 submarine-launched ballistic missile (SLBM) shared a substantial amount of technology with these boosters.In February 2000, the suspected nose cone of an Ariane 5 booster washed ashore on the South Texas coast, and was recovered by beachcombers before the government could get to it.=== Second stage ===EPS Upper Stage used on Ariane 5ESThe second stage was on top of the main stage and below the payload.", "The original Ariane — Ariane 5G — used the EPS (''Étage à Propergols Stockables'' — Storable Propellant Stage), which was fueled by monomethylhydrazine (MMH) and nitrogen tetroxide, containing of storable propellant.", "The EPS was subsequently improved for use on the Ariane 5G+, GS, and ES.The EPS upper stage was capable of repeated ignition, first demonstrated during flight V26 which was launched on 5 October 2007.This was purely to test the engine, and occurred after the payloads had been deployed.", "The first operational use of restart capability as part of a mission came on 9 March 2008, when two burns were made to deploy the first Automated Transfer Vehicle (ATV) into a circular parking orbit, followed by a third burn after ATV deployment to de-orbit the stage.", "This procedure was repeated for all subsequent ATV flights.Ariane 5ECA used the ESC (''Étage Supérieur Cryotechnique'' — Cryogenic Upper Stage), which was fueled by liquid hydrogen and liquid oxygen.", "The ESC used the HM7B engine previously used in the Ariane 4 third stage.", "The propellent load of 14.7 tonne allowed the engine to burn for 945 seconds while providing 6.5 tonne of thrust.", "The ESC provided roll control during powered flight and full attitude control during payload separation using hydrogen gas thrusters.", "Oxygen gas thrusters allowed longitudinal acceleration after engine cutoff.", "The flight assembly included the Vehicle Equipment Bay, with flight electronics for the entire rocket, and the payload interface and structural support.=== Fairing ===The payload and all upper stages were covered at launch by a fairing for aerodynamic stability and protection from heating during supersonic flight and acoustic loads.", "It was jettisoned once sufficient altitude has been reached, typically above .", "It was made by Ruag Space and since flight VA-238 it was composed of 4 panels." ], [ "Variants", " Variant Description '''G''' The original version was dubbed Ariane 5G (Generic) and had a launch mass of .", "Its payload capability to geostationary transfer orbit (GTO) was for a single satellite or for dual launches.", "It flew 16 times with one failure and two partial failures.", "'''G+''' The Ariane 5G+ had an improved EPS second stage, with a GTO capacity of for a single payload or for two.", "It flew three times in 2004, with no failures.", "'''GS''' At the time of the failure of the first Ariane 5ECA flight in 2002, all Ariane 5 launchers in production were ECA versions.", "Some of the ECA cores were modified to use the original Vulcain engine and tank volumes while the failure was investigated; these vehicles were designated Ariane 5GS.", "The GS used the improved EAP boosters of the ECA variant and the improved EPS of the G+ variant, but the increased mass of the modified ECA core compared to the G and G+ core resulted in slightly reduced payload capacity.", "Ariane 5GS could carry a single payload of or a dual payload of to GTO.", "The Ariane 5GS flew 6 times from 2005 to 2009 with no failures.", "'''ECA''' The Ariane 5ECA (''Evolution Cryotechnique type A''), first successfully flown in 2005, used an improved Vulcain 2 first-stage engine with a longer, more efficient nozzle with a more efficient flow cycle and denser propellant ratio.", "The new ratio required length modifications to the first-stage tanks.", "The EPS second stage was replaced by the ESC-A (''Etage Supérieur Cryogénique''-A), which had a dry weight of and was powered by an HM-7B engine burning of cryogenic propellant.", "The ESC-A used the liquid oxygen tank and lower structure from the Ariane 4's H10 third stage, mated to a new liquid hydrogen tank.", "Additionally, the EAP booster casings were lightened with new welds and carry more propellant.", "The Ariane 5ECA started with a GTO launch capacity of for dual payloads or for a single payload.", "Later batches: PB+ and PC, increased the max payload to GTO to .", "'''ES''' The Ariane 5ES (''Evolution Storable'') had an estimated LEO launch capacity of .", "It included all the performance improvements of Ariane 5ECA core and boosters but replaced the ESC-A second stage with the restartable EPS used on Ariane 5GS variants.", "It was used to launch the Automated Transfer Vehicle (ATV) into a circular low Earth orbit inclined at 51.6° and was used 3 times to launch 4 Galileo navigation satellites at a time directly into their operational orbit.", "The Ariane 5ES flew 8 times from 2008 to 2018 with no failures.", "'''ME''' The Ariane 5ME (''Mid-life Evolution'') was under development until the end of 2014.The last ESA ministerial council of December 2014 has cut further funding for Ariane 5ME in favour of developing Ariane 6.Last activities for Ariane 5ME were completed at the end of 2015.Activities on development of the VINCI upper stage were transferred to Ariane 6.", "'''Launch system status:'''" ], [ "Launch pricing and market competition", ", the Ariane 5 commercial launch price for launching a \"midsize satellite in the lower position\" was approximately €50 million, competing for commercial launches in an increasingly competitive market.The heavier satellite was launched in the upper position on a typical dual-satellite Ariane 5 launch and was priced higher than the lower satellite, on the order of €90 million .Total launch price of an Ariane 5 – which could transport up to two satellites to space, one in the \"upper\" and one in the \"lower\" positions – was around €150 million ." ], [ "Cancelled plans for future developments", "Belgian components produced for the Ariane 5 European heavy-lift launch vehicle explained=== Ariane 5 ME ===The Ariane 5 '''ME''' (Mid-life Evolution) was in development into early 2015, and was seen as a stopgap between Ariane 5ECA/Ariane 5ES and the new Ariane 6.With first flight planned for 2018, it would have become ESA's principal launcher until the arrival of the new Ariane 6 version.", "ESA halted funding for the development of Ariane 5ME in late 2014 to prioritize development of Ariane 6.The Ariane 5ME was to use a new upper stage, with increased propellant volume, powered by the new Vinci engine.", "Unlike the HM-7B engine, it was to be able to restart several times, allowing for complex orbital maneuvers such as insertion of two satellites into different orbits, direct insertion into geosynchronous orbit, planetary exploration missions, and guaranteed upper stage deorbiting or insertion into graveyard orbit.", "The launcher was also to include a lengthened fairing up to and a new dual launch system to accommodate larger satellites.", "Compared to an Ariane 5ECA model, the payload to GTO was to increase by 15% to and the cost-per-kilogram of each launch was projected to decline by 20%.==== Development ====Originally known as the Ariane 5'''ECB''', Ariane 5ME was to have its first flight in 2006.However, the failure of the first ECA flight in 2002, combined with a deteriorating satellite industry, caused ESA to cancel development in 2003.Development of the Vinci engine continued, though at a lower pace.", "The ESA Council of Ministers agreed to fund development of the new upper stage in November 2008.In 2009, EADS Astrium was awarded a €200 million contract, and on 10 April 2012 received another €112 million contract to continue development of the Ariane 5ME with total development effort expected to cost €1 billion.On 21 November 2012, ESA agreed to continue with the Ariane 5ME to meet the challenge of lower priced competitors.", "It was agreed the Vinci upper stage would also be used as the second stage of a new Ariane 6, and further commonality would be sought.", "Ariane 5ME qualification flight was scheduled for mid-2018, followed by gradual introduction into service.On 2 December 2014, ESA decided to stop funding the development of Ariane 5ME and instead focus on Ariane 6, which was expected to have a lower cost per launch and allow more flexibility in the payloads (using two or four P120C solid boosters depending on total payload mass).=== Solid propellant stage ===Work on the Ariane 5 EAP motors was continued in the Vega programme.", "The Vega 1st stage engine – the P80 engine – was a shorter derivation of the EAP.", "The P80 booster casing was made of filament wound graphite epoxy, much lighter than the current stainless steel casing.", "A new composite steerable nozzle was developed while new thermal insulation material and a narrower throat improved the expansion ratio and subsequently the overall performance.", "Additionally, the nozzle had electromechanical actuators which replaced the heavier hydraulic ones used for thrust vector control.These developments could maybe have made their way back into the Ariane programme, but this was most likely an inference based on early blueprints of the Ariane 6 having a central P80 booster and 2-4 around the main one.", "The incorporation of the ESC-B with the improvements to the solid motor casing and an uprated Vulcain engine would have delivered to LEO.", "This would have been developed for any lunar missions but the performance of such a design might not have been possible if the higher Max-Q for the launch of this launch vehicle would have posed a constraint on the mass delivered to orbit." ], [ "Ariane 6", "The design brief of the next generation launch vehicle Ariane 6 called for a lower-cost and smaller launch vehicle capable of launching a single satellite of up to to GTO.", "However, after several permutations the finalized design was nearly identical in performance to the Ariane 5, focusing instead on lowering fabrication costs and launch prices.", ", Ariane 6 was projected to be launched for about €70 million per flight, about half of the Ariane 5 price.Initially development of Ariane 6 was projected to cost €3.6 billion.", "In 2017, the ESA set 16 July 2020 as the deadline for the first flight.", "As of June 2022, Arianespace expects the maiden flight to occur in 2023." ], [ "Notable launches", "KourouAriane 5's first test flight (Ariane 5 Flight 501) on 4 June 1996 failed, with the rocket self-destructing 37 seconds after launch because of a malfunction in the control software.", "A data conversion from 64-bit floating-point value to 16-bit signed integer value to be stored in a variable representing horizontal bias caused a processor trap (operand error) because the floating-point value was too large to be represented by a 16-bit signed integer.", "The software had been written for the Ariane 4 where efficiency considerations (the computer running the software had an 80% maximum workload requirement) led to four variables being protected with a handler while three others, including the horizontal bias variable, were left unprotected because it was thought that they were \"physically limited or that there was a large margin of safety\".", "The software, written in Ada, was included in the Ariane 5 through the reuse of an entire Ariane 4 subsystem despite the fact that the particular software containing the bug, which was just a part of the subsystem, was not required by the Ariane 5 because it has a different preparation sequence than the Ariane 4.The second test flight (L502, on 30 October 1997) was a partial failure.", "The Vulcain nozzle caused a roll problem, leading to premature shutdown of the core stage.", "The upper stage operated successfully, but it could not reach the intended orbit.", "A subsequent test flight (L503, on 21 October 1998) proved successful and the first commercial launch (L504) occurred on 10 December 1999 with the launch of the XMM-Newton X-ray observatory satellite.Another partial failure occurred on 12 July 2001, with the delivery of two satellites into an incorrect orbit, at only half the height of the intended GTO.", "The ESA Artemis telecommunications satellite was able to reach its intended orbit on 31 January 2003, through the use of its experimental ion propulsion system.The next launch did not occur until 1 March 2002, when the Envisat environmental satellite successfully reached an orbit of above the Earth in the 11th launch.", "At , it was the heaviest single payload until the launch of the first ATV on 9 March 2008, at .The first launch of the ECA variant on 11 December 2002 ended in failure when a main booster problem caused the rocket to veer off-course, forcing its self-destruction three minutes into the flight.", "Its payload of two communications satellites (STENTOR and Hot Bird 7), valued at about €630 million, was lost in the Atlantic Ocean.", "The fault was determined to have been caused by a leak in coolant pipes allowing the nozzle to overheat.", "After this failure, Arianespace SA delayed the expected January 2003 launch for the Rosetta mission to 26 February 2004, but this was again delayed to early March 2004 due to a minor fault in the foam that protects the cryogenic tanks on the Ariane 5.The failure of the first ECA launch was the last failure of an Ariane 5 until flight 240 in January 2018.On 27 September 2003, the last Ariane 5G boosted three satellites (including the first European lunar probe, SMART-1), in Flight 162.On 18 July 2004, an Ariane 5G+ boosted what was at the time the heaviest telecommunication satellite ever, Anik F2, weighing almost .The first successful launch of the Ariane 5ECA took place on 12 February 2005.The payload consisted of the XTAR-EUR military communications satellite, a 'SLOSHSAT' small scientific satellite and a MaqSat B2 payload simulator.", "The launch had been scheduled for October 2004, but additional testing and a military launch (of a Helios 2A observation satellite) delayed the attempt.On 11 August 2005, the first Ariane 5GS (featuring the Ariane 5ECA's improved solid motors) boosted Thaicom 4, the heaviest telecommunications satellite to date at , into orbit.On 16 November 2005, the third Ariane 5ECA launch (the second successful ECA launch) took place.", "It carried a dual payload consisting of Spaceway F2 for DirecTV and Telkom-2 for PT Telekomunikasi of Indonesia.", "This was the launch vehicle's heaviest dual payload to date, at more than .On 27 May 2006, an Ariane 5ECA launch vehicle set a new commercial payload lifting record of .", "The dual-payload consisted of the Thaicom 5 and Satmex 6 satellites.On 4 May 2007, the Ariane 5ECA set another new commercial record, lifting into transfer orbit the Astra 1L and Galaxy 17 communication satellites with a combined weight of , and a total payload weight of .", "This record was again broken by another Ariane 5ECA, launching the Skynet 5B and Star One C1 satellites, on 11 November 2007.The total payload weight for this launch was of .On 9 March 2008, the first Ariane 5ES-ATV was launched to deliver the first ATV called ''Jules Verne'' to the International Space Station (ISS).", "The ATV was the heaviest payload ever launched by a European launch vehicle, providing supplies to the space station with necessary propellant, water, air and dry cargo.", "This was the first operational Ariane mission which involved an engine restart in the upper stage.", "The ES-ATV Aestus EPS upper stage was restartable while the ECA HM7-B engine was not.On 1 July 2009, an Ariane 5ECA launched TerreStar-1 (now EchoStar T1), which was then, at , the largest and most massive commercial telecommunication satellite ever built at that time until being overtaken by Telstar 19 Vantage, at , launched aboard Falcon 9.The satellite was launched into a lower-energy orbit than a usual GTO, with its initial apogee at roughly .On 28 October 2010, an Ariane 5ECA launched Eutelsat's W3B (part of its W Series of satellites) and Broadcasting Satellite System Corporation (B-SAT)'s BSAT-3b satellites into orbit.", "But the W3B satellite failed to operate shortly after the successful launch and was written off as a total loss due to an oxidizer leak in the satellite's main propulsion system.", "The BSAT-3b satellite, however, is operating normally.The VA253 launch on 15 August 2020 introduced two small changes that increased lift capacity by about ; these were a lighter avionics and guidance-equipment bay, and modified pressure vents on the payload fairing, which were required for the subsequent launch of the James Webb Space Telescope.", "It also debuted a location system using Galileo navigation satellites.On 25 December 2021, VA256 launched the James Webb Space Telescope towards a Sun–Earth L2 halo orbit.", "The precision of trajectory following launch led to fuel savings credited with potentially doubling the lifetime of the telescope by leaving more hydrazine propellant on-board for station-keeping than was expected.", "According to Rudiger Albat, the program manager for Ariane 5, efforts had been made to select components for this flight that had performed especially well during pre-flight testing, including \"one of the best Vulcain engines that we've ever built.", "\"=== GTO payload weight records ===On 22 April 2011, the Ariane 5ECA flight VA-201 broke a commercial record, lifting Yahsat 1A and Intelsat New Dawn with a total payload weight of to transfer orbit.", "This record was later broken again during the launch of Ariane 5ECA flight VA-208 on 2 August 2012, lifting a total of into the planned geosynchronous transfer orbit, which was broken again 6 months later on flight VA-212 with sent towards geosynchronous transfer orbit.", "In June 2016, the GTO record was raised to , on the first rocket in history that carried a satellite dedicated to financial institutions.", "The payload record was pushed a further , up to on 24 August 2016 with the launch of Intelsat 33e and Intelsat 36.On 1 June 2017, the payload record was broken again to carrying ViaSat-2 and Eutelsat-172B.", "In 2021 VA-255 put 11,210 kg into GTO.=== VA241 anomaly ===On 25 January 2018, an Ariane 5ECA launched SES-14 and Al Yah 3 satellites.", "About 9 minutes and 28 seconds after launch, a telemetry loss occurred between the launch vehicle and the ground controllers.", "It was later confirmed, about 1 hour and 20 minutes after launch, that both satellites were successfully separated from the upper stage and were in contact with their respective ground controllers, but that their orbital inclinations were incorrect as the guidance systems might have been compromised.", "Therefore, both satellites conducted orbital procedures, extending commissioning time.", "SES-14 needed about 8 weeks longer than planned commissioning time, meaning that entry into service was reported early September instead of July.", "Nevertheless, SES-14 is still expected to be able to meet the designed lifetime.", "This satellite was originally to be launched with more propellant reserve on a Falcon 9 launch vehicle since the Falcon 9, in this specific case, was intended to deploy this satellite into a high inclination orbit that would require more work from the satellite to reach its final geostationary orbit.", "The Al Yah 3 was also confirmed healthy after more than 12 hours without further statement, and like SES-14, Al Yah 3's maneuvering plan was also revised to still fulfill the original mission.", "As of 16 February 2018, Al Yah 3 was approaching the intended geostationary orbit, after series of recovery maneuvers had been performed.", "The investigation showed that invalid inertial units' azimuth value had sent the vehicle 17° off course but to the intended altitude, they had been programmed for the standard geostationary transfer orbit

[ [ "Arianespace" ], [ "Introduction", "'''Arianespace SA''' is a French company founded in 1980 as the world's first commercial launch service provider.", "It undertakes the operation and marketing of the Ariane programme.", "The company offers a number of different launch vehicles: the heavy-lift Ariane 5 for dual launches to geostationary transfer orbit, the Soyuz-2 as a medium-lift alternative, and the solid-fueled Vega for lighter payloads., Arianespace had launched more than 850 satellites in 287 launches over 41 years.", "The first commercial flight managed by the new entity was Spacenet F1 launched on 23 May 1984.Arianespace uses the Guiana Space Centre in French Guiana as its main launch site.", "Through shareholding in Starsem, it can also offer commercial Soyuz launches from the Baikonur spaceport in Kazakhstan.", "It has its headquarters in Évry-Courcouronnes, Essonne, France." ], [ "History", "The formation of Arianespace SA is closely associated with the desire of several European nations to pursue joint collaboration in the field of space exploration and the formation of a pan-national organisation, the European Space Agency (ESA), to oversee such undertaking during 1973.Prior to the ESA's formation, France had been lobbying for the development of a new European expendable launch system to serve as a replacement for the Europa rocket.", "Accordingly, one of the first programmes launched by the ESA was the Ariane heavy launcher.", "The express purpose of this launcher was to facilitate the delivery of commercial satellites into geosynchronous orbit.Ariane 1 mock-upFrance was the largest stakeholder in the Ariane development programme.", "French aerospace manufacturer Aérospatiale served as the prime contractor and held responsibility for performing the integration of all sections of the vehicle, while French engine manufacturer Société Européenne de Propulsion (SEP) provided the first, second and third stage engines (the third stage engines were produced in partnership with German aerospace manufacturer MBB).", "Other major companies involved included the French firms Air Liquide and Matra, Swedish manufacturer Volvo, and German aircraft producer Dornier Flugzeugwerke.", "Development of the third stage was a major focus point for the project - prior to Ariane, only the United States had ever flown a launcher that utilised hydrogen-powered upper stages.Immediately following the successful first test launch of an Ariane 1 on 24 December 1979, the French space agency Centre national d'études spatiales (CNES) and the ESA created a new company, ''Arianespace'', for the purpose of promoting, marketing, and managing Ariane operations.", "According to Arianespace, at the time of its establishment, it was the world's first launch services company.", "Following a further three test launches, the first commercial launch took place on 10 September 1982, which ended in failure as a result of a turbopump having failed in the third stage.", "The six remaining flights of the Ariane 1 were successful, with the final flight occurring during February 1986.As a result of these repeated successes, orders for the Ariane launcher quickly mounted up; by early 1984, a total of 27 satellites had been booked to use Ariane, which was estimated to be half of the world's market at that time.", "As a result of the commercial success, after the tenth Ariane mission was flown, the ESA formally transferred responsibility for Ariane over to Arianespace.By early 1986, the Ariane 1, along with its Ariane 2 and Ariane 3 derivates, were the dominant launcher on the world market.", "The Ariane 2 and Ariane 3 were short-lived platforms while the more extensive Ariane 4 was being developed; it was a considerably larger and more flexible launcher that the earlier members of its family, having been intended from the onset to compete with the upper end of launchers worldwide.", "In comparison, while the Ariane 1 had a typical weight of 207 tonnes and could launch payloads of up to 1.7 tonnes into orbit; the larger Ariane 4 had a typical weight of 470 tonnes and could orbit payloads of up to 4.2 tonnes.", "Despite this, the Ariane 4 was actually 15 per cent smaller than the Ariane 3.On 15 June 1988, the first successful launch of the Ariane 4 was conducted.", "This maiden flight was considered a success, having placed multiple satellites into orbit.", "For the V50 launch onwards, an improved third stage, known as the ''H10+'', was adopted for the Ariane 4, which raised the rocket's overall payload capacity by 110 kg and increased its burn time by 20 seconds.Ariane 4 on launch padEven prior to the first flight of the Ariane 4 in 1988, development of a successor, designated as the Ariane 5, had already commenced.", "In January 1985, the Ariane 5 was officially adopted as an ESA programme, and began an eleven-year development and test program to the first launch in 1996.It lacked the high levels of commonality that the Ariane 4 had with its predecessors, and had been designed not only for launching heavier payloads of up to 5.2 tonnes and at a 20 per cent cost reduction over the Ariane 4, but for a higher margin of safety due to the fact that the Ariane 5 was designed to conduct crewed space launches as well, being intended to transport astronauts using the proposed Hermes space vehicle.", "Development of the Ariane 5 was not without controversy as some ESA members considered the mature Ariane 4 platform to be more suited for meeting established needs for such launchers; it was reportedly for this reason that Britain chose not to participate in the Ariane 5 programme.", "For several years, Ariane 4 and Ariane 5 launchers were operated interchangeably; however, it was eventually decided to terminate all Ariane 4 operations in favour of concentrating on the newer Ariane 5.During the mid-1990s, French firms Aérospatiale and SEP, along with Italian firm Bombrini-Parodi-Delfino (BPD), held discussions on the development of a proposed Ariane Complementary Launcher (ACL).", "Simultaneously, Italy championed the concept of a new solid-propellant satellite launcher, referred to as Vega.", "During March 2003, contracts for Vega's development were signed by the ESA and CNES; Italy provided 65 per cent of funding while six additional nations contributed the remainder.", "In May 2004, it was reported that a contract was signed between commercial operator Arianespace and prime contractor ELV to perform vehicle integration at Kourou, French Guiana.", "On 13 February 2012, the first launch of the Vega took place; it was reported as being an \"apparently perfect flight\".", "Since entering commercial service, Arianespace markets Vega as a launch system tailored for missions to polar and Sun-synchronous orbits.During 2002, the ESA announced the Arianespace Soyuz programme in cooperation with Russia; a launch site for Soyuz was constructed as the Guiana Space Centre, while the Soyuz launch vehicle was modified for use at the site.", "On 4 February 2005, both funding and final approval for the initiative were granted.", "Arianespace had offered launch services on the modified Soyuz ST-B to its clients.", "On 21 October 2011, Arianespace launched the first Soyuz rocket ever from outside former Soviet territory.", "The payload consisted of two Galileo navigation satellites.", "Since 2011, Arianespace has ordered a total of 23 Soyuz rockets, enough to cover its needs until 2019 at a pace of three to four launches per year.On 21 January 2019, ArianeGroup and Arianespace announced that it had signed a one-year contract with the ESA to study and prepare for a mission to the Moon to mine regolith.In 2020, Arianespace suspended operations for nearly two months due to the COVID-19 pandemic.", "Operations were suspended on 18 March and are, as of 29 April, expected to resume on 11 May.", "The return to operations will observe a number of new health and safety guidelines including social distancing in the workplace.In 2023,Ariane 5 was Retired with the introduction of New Ariane 6 expected to take its maiden flight Between June -July 2024" ], [ "Company and infrastructure", "Vega launcher on launch padArianespace \"is the marketing and sales organization for the European space industry and various component suppliers.", "\"The primary shareholders of Arianespace are its suppliers, in various European nations.Arianespace had 24 shareholders in 2008, 21 in 2014,and just 17 .CountryTotal shareShareholderCapital 3.36% SABCA 2.71% Thales Alenia Space Belgium 0.33% 0.32% 64.10% ArianeGroup 62.10% Air Liquide SA 1.89% 0.11% CIE Deutsche <0.01% 19.85% ArianeGroup 11.59% AG 8.26% 3.38% Avio S.p.A. 3.38% 1.94% Airbus Defence and Space B.V. 1.94% 0.11% Kongsberg Defence & Aerospace AS 0.11% 2.14% Airbus Defence and Space SAU 2.03% CRISA 0.11% 2.45% GKN Aerospace Sweden AB 1.63% RUAG Space AB 0.82% 2.67% RUAG Schweiz AG 2.67%In 2015, Arianespace shareholding was restructured due to the creation of Airbus Safran Launchers (later renamed ArianeGroup), which is tasked with developing and manufacturing the Ariane 6 carrier rocket.", "Industrial groups Airbus and Safran pooled their shares along with the French government's CNES stake to form a partnership company holding just under 74% of Arianespace shares, while the remaining 26% is spread across suppliers in nine countries including further Airbus subsidiaries.===Corporate management===, the Arianespace management team was: Position Name Arianespace Chief Executive Officer, ArianeGroup Executive VP Stéphane Israël Senior Vice-President, Sales & Business Development Jacques Breton Senior Vice-President, Missions, Operations & Purchasing Luce Fabreguettes Senior Vice President – Technical and Quality;

the same denominator then they must be transformed to find a common denominator.", "This can be achieved by scaling the first number with the denominator of the second number while scaling the second number with the denominator of the first number.", "For instance, .Two rational numbers are multiplied by multiplying their numerators and their denominators respectively, as in .", "Dividing one rational number by another can be achieved by multiplying the first number with the reciprocal of the second number.", "This means that the numerator and the denominator of the second number change position.", "For example, .", "Unlike integer arithmetic, rational number arithmetic is closed under division as long as the divisor is not 0.Both integer arithmetic and rational number arithmetic are not closed under exponentiation and logarithm.", "One way to calculate exponentiation with a fractional exponent is to perform two separate calculations: one exponentiation using the numerator of the exponent followed by drawing the nth root of the result based on the denominator of the exponent.", "For example, .", "The first operation can be completed using methods like repeated multiplication or exponentiation by squaring.", "One way to get an approximate result for the second operation is to employ Newton's method, which uses a series of steps to gradually refine an initial guess until it reaches the desired level of accuracy.", "The Taylor series or the continued fraction method can be utilized to calculate logarithms.The decimal fraction notation is a special way of representing

calculation methods like addition with carry and long multiplication can be applied to calculations with decimal fractions.", "Not all rational numbers have a finite representation in the decimal notation.", "For example, the rational number corresponds to 0.333... with an infinite number of 3s.", "The shortened notation for this type of repeating decimal is 0.. Every repeating decimal expresses a rational number.=== Real number arithmetic ===Real number arithmetic is the branch of arithmetic that deals with the manipulation of both rational and irrational numbers.", "Irrational numbers are numbers that cannot be expressed through fractions or repeated decimals, like the root of 2 and .", "Unlike rational number arithmetic, real number arithmetic is closed under exponentiation as long as it uses a positive number as its base.", "The same is true for the logarithm of positive real numbers as long as the logarithm base is positive and not

with 3.14159... .", "If this number is truncated to 4 significant digits, the result is 3.141.Rounding is a similar process in which the last significant digit is increased by one if the next digit is 5 or greater.", "If the next digit is less than 5, the last digit remains the same.", "For instance, if the number is rounded to 4 significant digits, the result is 3.142 because the following digit is a 5.These methods are essential to allow computers to efficiently perform calculations on real numbers.Very large and very small real numbers are often expressed using normalized scientific notation.", "In it, numbers are represented using a so-called ''significand'' multiplied by a power of 10.The significand is a digit followed by a decimal point and a series of digits.", "For example, the normalized scientific notation of the number 8276000 is and the number 0.00735 has the normalized scientific notation of .A common method employed by computers to approximate real number arithmetic is called floating-point arithmetic.", "It represents real numbers similar to the scientific notation through three numbers: a significand, a base, and an exponent.", "The precision of the significand is limited by the number of bits allocated to represent it.", "If an arithmetic operation results in a number that requires more bits than are available, the computer rounds the result to the closest representable number.", "This leads to rounding errors.", "A consequence of this behavior is that certain laws of arithmetic are violated by floating-point arithmetic.", "For example, floating-point addition is not associative since the rounding errors introduced can depend on the order of the additions.", "This means that the result of is sometimes different from the result of .", "The most common technical standard used for floating-point arithmetic is called IEEE 754.Among other things, it determines how numbers are represented, how arithmetic operations and rounding are performed, and how errors and exceptions are handled.", "In cases where computation speed is not a limiting factor, it is possible to use arbitrary-precision arithmetic, for which the precision of calculations is only restricted by the computer's memory.=== Tool use ===Calculations in mental arithmetic are done exclusively in the mind without relying on external aids.Forms of arithmetic can also be distinguished by the tools employed to perform calculations and include many approaches besides the regular use of pen and paper.", "Mental arithmetic relies exclusively on the mind without external tools.", "Instead, it utilizes visualization, memorization, and certain calculation techniques to solve arithmetic problems.", "One such technique is the compensation method, which consists in altering the numbers to make the calculation easier and then adjusting the result afterward.", "For example, instead of calculating , one calculates which is easier because it uses a round number.", "In the next step, one adds to the result to compensate for the earlier adjustment.", "Mental arithmetic is often taught in primary education to train the numerical abilities of the students.The human body can also be employed as an arithmetic tool.", "The use of hands in finger counting is often introduced to young children to teach them numbers and simple calculations.", "In its most basic form, the number of extended fingers corresponds to the represented quantity and arithmetic operations like addition and subtraction are performed by extending or retracting fingers.", "This system is limited to small numbers while more advanced systems employ different approaches to represent larger quantities as well.", "The human voice is used as an arithmetic aid in verbal counting.Abacuses are tools to perform arithmetic operations by moving beads.Tally marks are a simple system based on external tools other than the body.", "It relies on strokes drawn on a surface or notches in a wooden stick to keep track of quantities.", "Some forms of tally marks arrange the strokes in groups of five to make them easier to read.", "The abacus is a more advanced tool to represent numbers and perform calculations.", "An abacus usually consists of a series of rods, each holding several beads.", "Each bead represents a quantity, which is counted if the bead is moved from one end of a rod to the other.", "Calculations happen by manipulating the positions of beads until the final bead pattern reveals the result.", "Related aids include counting boards, which use tokens whose value depends on the area on the board in which they are placed, and counting rods, which are arranged in horizontal and vertical patterns to represent different numbers.", "Sectors and slide rules are more refined calculating instruments that rely on geometric relationships between different scales to perform both basic and advanced arithmetic operations.", "Printed tables were particularly relevant as an aid to look up the results of operations like logarithm and trigonometric functions.Mechanical calculators automate manual calculation processes.", "They present the user with some form of input device to enter numbers by turning dials or pressing keys.", "They include an internal mechanism usually consisting of gears, levers, and wheels to perform calculations and display the results.", "For electronic calculators and computers, this procedure is further refined by replacing the mechanical components with electronic circuits like processors that combine and transform electric signals to perform calculations.=== Others ===Example of modular arithmetic using a clock: after adding 4 hours to 9 o'clock, the hand starts at the beginning again and points at 1 o'clock.There are many other types of arithmetic.", "Modular arithmetic operates on a finite set of numbers.", "If an operation would result in a number outside this finite set then the number is adjusted back into the set, similar to how the hands of clocks start at the beginning again after having completed one cycle.", "The number at which this adjustment happens is called the modulus.", "For example, a regular clock has a modulus of 12.In the case of adding 4 to 9, this means that the result is not 13 but 1.The same principle applies also to other operations, such as subtraction, multiplication, and division.Some forms of arithmetic deal with operations performed on mathematical objects other than numbers.", "Interval arithmetic describes operations on intervals.", "Intervals can be used to represent a range of values if one does not know the precise magnitude, for example, because of measurement errors.", "Interval arithmetic includes operations like addition and multiplication on intervals, as in and .", "It is closely related to affine arithmetic, which aims to give more precise results by performing calculations on affine forms rather than intervals.", "An affine form is a number together with error terms that describe how the number may deviate from the actual magnitude.", "Vector arithmetic and matrix arithmetic describe arithmetic operations on vectors and matrices, like vector addition and matrix multiplication.Arithmetic systems can be classified based on the numeral system they rely on.", "For instance, decimal arithmetic describes arithmetic operations in the decimal system.", "Other examples are binary arithmetic, octal arithmetic, and hexadecimal arithmetic.Compound unit arithmetic describes arithmetic operations performed on magnitudes with compound units.", "It involves additional operations to govern the transformation between single unit and compound unit quantities.", "For example, the operation of reduction is used to transform the compound quantity 1 h 90 min into the single unit quantity 150 min.Non-Diophantine arithmetics are arithmetic systems that violate traditional arithmetic intuitions and include equations like and .", "They can be employed to represent some real-world situations in modern physics and everyday life.", "For instance, the equation can be used to describe the observation that if one raindrop is added to another raindrop then they do not remain two separate entities but become one." ], [ "Axiomatic foundations", "Axiomatic foundations of arithmetic try to provide a small set of laws, so-called axioms, from which all fundamental properties of and operations on numbers can be derived.", "They constitute logically consistent and systematic frameworks that can be used to formulate mathematical proofs in a rigorous manner.", "Two well-known approaches are the Dedekind–Peano axioms and set-theoretic constructions.The Dedekind–Peano axioms provide an axiomatization of the arithmetic of natural numbers.", "Their basic principles were first formulated by Richard Dedekind and later refined by Giuseppe Peano.", "They rely only on a small number of primitive mathematical concepts, such as 0, natural number, and successor.", "The Peano axioms determine how these concepts are related to each other.", "All other arithmetic concepts can then be defined in terms of these primitive concepts.# 0 is a natural number.# For every natural number, there is a successor, which is also a natural number.# The successors of two different natural numbers are never identical.# 0 is not the successor of a natural number.# If a set contains 0 and every successor then it contains every natural number.Numbers greater than 0 are expressed by repeated application of the successor function .", "For example, is and is .", "Arithmetic operations can be defined as mechanisms that affect how the successor function is applied.", "For instance, to add to any number is the same as applying the successor function two times to this number.Various axiomatizations of arithmetic rely on set theory.", "They cover natural numbers but can also be extended to integers, rational numbers, and real numbers.", "Each natural number is represented by a unique set.", "0 is usually defined as the empty set .", "Each subsequent number can be defined as the union of the previous number with the set containing the previous number.", "For example, , , and .", "Integers can be defined as ordered pairs of natural numbers where the second number is subtracted from the first one.", "For instance, the pair (9, 0) represents the number 9 while the pair (0, 9) represents the number -9.Rational numbers are defined as pairs of integers where the first number represents the numerator and the second number represents the denominator.", "For example, the pair (3, 7) represents the rational number .", "One way to construct the real numbers relies on the concept of Dedekind cuts.", "According to this approach, each real number is represented by a partition of all rational numbers into two sets, one for all numbers below the represented real number and the other for the rest.", "Arithmetic operations are defined as functions that perform various set-theoretic transformations on the sets representing the input numbers to arrive at the set representing the result." ], [ "History", "Some historians interpret the Ishango bone as one of the earliest arithmetic artifacts.The earliest forms of arithmetic are sometimes traced back to counting and tally marks used to keep track of quantities.", "Some historians suggest that the Lebombo bone (dated about 43,000 years ago) and the Ishango bone (dated about 22,000 to 30,000 years ago) are the oldest arithmetic artifacts but this interpretation is disputed.", "However, a basic sense of numbers may predate these findings and might even have existed before the development of language.It was not until the emergence of ancient civilizations that a more complex and structured approach to arithmetic began to evolve, starting around 3000 BCE.", "This became necessary because of the increased need to keep track of stored items, manage land ownership, and arrange exchanges.", "All the major ancient civilizations developed non-positional numeral systems to facilitate the representation of numbers.", "They also had symbols for operations like addition and subtraction and were aware of fractions.", "Examples are Egyptian hieroglyphics as well as the numeral systems invented in Sumeria, China, and India.", "The first positional numeral system was developed by the Babylonians starting around 1800 BCE.", "This was a significant improvement over earlier numeral systems since it made the representation of large numbers and calculations on them more efficient.", "Abacuses have been utilized as hand-operated calculating tools since ancient times as efficient means for performing complex calculations.Early civilizations primarily used numbers for concrete practical purposes and lacked an abstract concept of number itself.", "This changed with the ancient Greek mathematicians, who began to explore the abstract nature of numbers rather than studying how they are applied to specific problems.", "Another novel feature was their use of proofs to establish mathematical truths and validate theories.", "A further contribution was their distinction of various classes of numbers, such as even numbers, odd numbers, and prime numbers.", "This included the discovery that numbers for certain geometrical lengths are irrational and therefore cannot be expressed as a fraction.", "The works of Thales of Miletus and Pythagoras in the 7th and 6th centuries BCE are often regarded as the inception of Greek mathematics.", "Diophantus was an influential figure in Greek arithmetic in the 3rd century BCE because of his numerous contributions to number theory and his exploration of the application of arithmetic operations to algebraic equations.The ancient Indians were the first to develop the concept of zero as a number to be used in calculations.", "The exact rules of its operation were written down by Brahmagupta in around 628 CE.", "The concept of zero or none existed long before, but it was not considered an object of arithmetic operations.", "Brahmagupta further provided a detailed discussion of calculations with negative numbers and their application to problems like credit and debt.", "The concept of negative numbers itself is significantly older and was first explored in Chinese mathematics in the first millennium BCE.Indian mathematicians also developed the positional decimal system used today, in particular the concept of a zero digit instead of empty/missing positions.", "For example, a detailed treatment of its operations was provided by Aryabhata around the turn of the 6th century CE.", "The Indian decimal system was further refined and expanded to non-integers during the Islamic Golden Age by Arab mathematicians such as Al-Khwarizmi.", "His work was influential in introducing the decimal numeral system to the Western world, which at that time relied on the Roman numeral system.", "There, it was popularized by mathematicians like Leonardo Fibonacci, who lived in the 12th and 13th centuries and also developed the Fibonacci sequence.", "During the Middle Ages and Renaissance, many popular textbooks were published to cover the practical calculations for commerce.", "The use of abacuses also became widespread in this

calculator and Gottfried Wilhelm Leibniz's stepped reckoner.", "The 17th century also saw the discovery of the logarithm by John Napier.In the 18th and 19th centuries, mathematicians such as Leonhard Euler and Carl Friedrich Gauss laid the foundations of modern number theory.", "Another development in this period concerned work on the formalization and foundations of arithmetic, such as Georg Cantor's set theory and the Dedekind–Peano axioms used as an axiomatization of natural-number arithmetic.", "Computers and electronic calculators were first developed in the 20th century.", "Their

fields.", "A lack of numeracy can inhibit academic success and lead to bad economic decisions in everyday life, for example, by misunderstanding mortgage plans and insurance policies.=== Philosophy ===The philosophy of arithmetic studies the fundamental concepts and principles underlying numbers and arithmetic operations.", "It explores the nature and ontological status of numbers, the relation of arithmetic to language and logic, and how it is possible to acquire arithmetic knowledge.According to Platonism, numbers have mind-independent existence: they exist as abstract objects outside spacetime and without causal powers.", "This view is rejected by intuitionists, who claim that mathematical objects are mental constructions.", "Further theories are logicism, which holds that mathematical truths are reducible to logical truths, and formalism, which states that mathematical principles are rules of how symbols are manipulated without claiming that they correspond to entities outside the rule-governed activity.The traditionally dominant view in the epistemology of arithmetic is that arithmetic truths are knowable a priori.", "This means that they can be known by thinking alone without the need to rely on sensory experience.", "Some proponents of this view state that arithmetic knowledge is innate while others claim that there is some form of rational intuition through

[ [ "Axiology" ], [ "Introduction", "'''Axiology''' (from Greek , ''axia'': \"value, worth\"; and , ''-logia'': \"study of\") is the philosophical study of value.", "It includes questions about the nature and classification of values and about what kinds of things have value.", "It is intimately connected with various other philosophical fields that crucially depend on the notion of value, like ethics, aesthetics or philosophy of religion.", "It is also closely related to value theory and meta-ethics.", "The term was first used by Eduard von Hartmann in 1887 and by Paul Lapie in 1902.The distinction between ''intrinsic'' and ''extrinsic'' value is central to axiology.", "One conceptualization holds that something is ''intrinsically valuable'' if it is ''good in itself'' or ''good for its own sake''.", "It is usually held that intrinsic value ''depends'' on certain features of the valuable entity.", "For example, an experience may be said to be intrinsically valuable ''by virtue of'' being (because it is) pleasurable or beautiful or \"true\" (e.g., the ascertainment of a fact can be said to be valuable in itself).", "''Extrinsic value'', by contrast, is ascribed to things that are valuable only as a ''means'' to something else.", "''Substantive theories'' of value try to determine which entities have intrinsic value.", "''Monist theories'' hold that there is only one type of intrinsic value.", "The paradigm example of monist theories is hedonism, the thesis that only pleasure has intrinsic value.", "''Pluralist theories'', on the other hand, contend that there are various different types of intrinsic value, for example, virtue, knowledge, friendship, etc.", "Value pluralists face the problem of explaining whether or how the different types of value can be compared when making rational decisions.", "Some philosophers state that values ''do not exist'' on the most fundamental level of reality.", "One such view holds that a value statement about something just expresses the speaker's approval or disapproval of this thing.", "This position is opposed by ''realists about value''." ], [ "History", "Between the 5th and 6th centuries BC, it was important in Greece to be knowledgeable if you were to be successful.", "Philosophers began to recognize that differences existed between the laws and morality of society.", "Socrates believed that knowledge had a vital connection to virtue, making morality and democracy closely intertwined.", "Socrates' student, Plato furthered the belief by establishing virtues which should be followed by all.E.", "J. Dijksterhuis found that axiological antithesis characterized the philosophy of ancient Greece:As with the fall of Rome so values became more individual and personal, causing skeptic schools of thought to flourish, helping to shape an ontologically objective philosophy that is thought to have contributed to Christian Philosophy.", "During the medieval period, Thomas Aquinas made the distinction between natural and supernatural (theological) virtues.", "This concept led philosophers to distinguish between judgments based on fact and judgments based on values, creating the division between science and philosophy." ], [ "Intrinsic value", "Traditionally, philosophers held that an entity has ''intrinsic value'' if it is ''good in itself'' or ''good for its own sake''.", "''Intrinsic value'' is contrasted with ''extrinsic or instrumental value'', which is ascribed to things that are valuable only as a ''means'' to something else.", "For example, tools like cars or microwaves are said to be extrinsically valuable by virtue of the function they perform, while the well-being they cause is intrinsically valuable, according to hedonism.", "The same entity can be valuable in different ways: some entities have both intrinsic and extrinsic values at the same time.", "Extrinsic values can form chains, in which one entity is extrinsically valuable because it is a means to another entity that is itself extrinsically valuable.", "It is commonly held that these chains must terminate somewhere and that the endpoint can only be intrinsically valuable.", "The distinction between intrinsic and extrinsic values is important for understanding various disagreements within axiology.", "Different substantive theories of value often agree on whether something, for example knowledge, is valuable while disagreeing on whether the value in question is intrinsic or extrinsic.The traditional conception of intrinsic value presented above has been criticized in contemporary philosophy on the grounds that it combines various distinct notions that are better discussed separately.", "One such contrast is between ''intrinsic'' and ''final'' values.", "On a more narrow conception, an ''intrinsic'' value is a value an entity has in virtue of its intrinsic properties.", "For example, assuming that the phenomenal aspect of a pleasant experience is an intrinsic property, we might say that the experience is intrinsically valuable because of this intrinsic property.", "An entity with ''final'' value, by contrast, is valuable for its own sake.", "It is usually accepted that there is a conceptual difference between intrinsic and final values.", "For example, the pleasure experience may be said to be intrinsically valuable on the one hand, and finally valuable on the other hand.", "But it has been disputed whether there are actual things where these value types can come apart.", "Proposed candidates for bearers of final non-intrinsic value include unique or rare items (e.g.", "a stamp) or historically significant items (e.g.", "the pen that Abraham Lincoln used to sign the Emancipation Proclamation).", "''Being-rare'' and ''having-been-used-by-someone'' are ''extrinsic'' properties that may be responsible for their bearers having ''final'' value, i.e.", "being valuable for their own sake.Some philosophers have questioned whether extrinsic values should be regarded as values at all rather than as mere indications of values.", "One reason for considering this idea is that adding or removing extrinsically valuable things does not affect the value of the whole if all intrinsically valuable things are kept constant.", "For example, the 2011 Tōhoku earthquake had a negative extrinsic value because of all the damage it caused.", "But arguably, the world would not have been a better place if exactly the same damage had been caused without the earthquake." ], [ "Ontological status of values", "In axiology, it is often important to distinguish between the entity that is valuable and the features in virtue of which it is valuable.", "For example, an experience may be said to be valuable in virtue of being pleasurable.", "This distinction is particularly relevant for intrinsic values since it is commonly held that the intrinsic value of an entity supervenes on its intrinsic features.", "This means that the entity could not have a different intrinsic value unless it had different intrinsic features.Substantive theories of value focus on the features in virtue of which something has intrinsic value.", "Popular candidates for these features include pleasure, virtue and knowledge.", "Another question concerns the nature of the entities that are the bearers of value.", "The main approaches to this question can be divided into the Kantian tradition, which considers concrete things like persons to be the bearers of value, and the Moorean tradition, which holds that only states of affairs bear value.", "This difference is important when determining whether a value is extrinsic or intrinsic to an entity.", "Some philosophers hold that objects like Napoleon's hat are valuable because of their relation to extraordinary persons.", "From a Kantian perspective, this value must be extrinsic since it is based on the extrinsic property of having been worn by an extraordinary person.", "But from a Moorean perspective, it can be intrinsic since it is born not by the hat but by a state of affairs involving both the hat and Napoleon.The preceding discussion about the ontological categories of values and value-bearers assumes some form of realism: that there actually are valuable things.", "But the difficulties in reaching expert consensus in value-related fields like ethics, aesthetics or politics and considerations from naturalism have led various philosophers to doubt this assumption.", "The ensuing dispute between cognitivists and non-cognitivists is usually held on the level of value-statements or value-attitudes, either concerning all values or specifically concerning ethical values.", "Cognitivists assert that value-statements are ''truth-apt'', i.e.", "are either true or false, which is denied by non-cognitivists.", "Most cognitivists are realists about values: they believe that values are part of reality.", "Error theory, as originally articulated by J. L. Mackie, is an exception.", "Error theorists hold that all value-statements are false, and thereby truth-apt, because the world lacks value-features that would be needed to make them true.", "Non-cognitivists, on the other hand, go one step further by denying that value-statements are truth-apt.", "This position involves the difficulty of explaining how value-statements can be meaningful despite lacking a truth value.", "This challenge can be met in different ways.", "Emotivists, following A. J. Ayer, state that value-statements only express the emotions of the speaker and are intended to influence the actions of the listener.", "Prescriptivism, as developed by R. M. Hare, interprets value-statements as imperatives or commands.", "Simon Blackburn's quasi-realism states that value statements project emotional attitudes as though they were real properties." ], [ "Monism and pluralism", "Substantive theories of value try to determine which entities have ''intrinsic value''.", "A traditional dispute in this field is between ''monist'' and ''pluralist'' theories.", "According to Chris Heathwood, monism and pluralism can be distinguished according to an evaluation of what is good in people and the concept of \"value simpliciter\" in terms of intrinsic value.", "Monist theories hold that there is only one type of intrinsic value.", "The paradigm example of monist theories is hedonism, the thesis that only pleasure has intrinsic value.", "Pluralist theories, on the other hand, contend that there are various different types of intrinsic value.", "They maintain that these types of intrinsic values cannot be reduced to a single feature of an act or entity.", "W. D. Ross, for example, holds that pleasure is only one type of intrinsic value besides other types, like knowledge.", "It is important to keep in mind that this disagreement only concerns ''intrinsic'' value, not value ''at large''.", "So hedonists may be happy to concede that knowledge is valuable, but only extrinsically so, given that knowledge can be helpful in causing pleasure and avoiding pain.Various arguments have been suggested in the monism-pluralism-dispute.", "Common-sense seems to favor value pluralism: values are ascribed to a wide range of different things like happiness, liberty, friendship, etc.", "without any obvious common feature underlying these values.", "One way to defend value monism is to cast doubt on the reliability of common-sense for technical matters like the distinction between intrinsic and extrinsic value.", "This strategy is pursued by J. J. C. Smart, who holds that there is a psychological bias to mistake stable extrinsic values for intrinsic values.", "Value pluralists have often attempted to provide exhaustive lists of all value types, but different theorists have suggested very different lists.", "These lists seem to constitute arbitrary selections unless a clear criterion could be provided why all and only these items are included.", "But if a criterion was to be found then such a theory would no longer be pluralistic.", "This dilemma suggests that pluralism is inadequate as an explanation.One issue closely related to the monism-pluralism-debate is the problem of incommensurability: the question of whether there are incommensurable values.", "Two values are ''incommensurable'' if there is no fact as to whether one is better than or as good as the other: there is ''no common value scale'' according to which they could be compared.", "According to Joseph Raz, career choices between very different paths, for example, whether to become a lawyer or a clarinetist, are cases where incommensurable values are involved.", "Value pluralists often assert that values belonging to different types are incommensurable with each other.", "Value monists, by contrast, usually deny that there are incommensurable values.", "This question is particularly relevant for ethics.", "If different options available to the agent embody incommensurable values then there seems to be no rational way to determine what ought to be done since there is no matter of fact as to which option is better.", "Widespread incommensurability would threaten to undermine the practical relevance of ethics and rational choice." ], [ "Other concepts and distinctions", "Many evaluative terms are found in everyday language, often with various different meanings.", "It is important for philosophers to distinguish these different meanings in order to avoid misunderstandings.", "One such distinction is between a ''predicative'' and an ''attributive'' sense of good and bad.", "In the ''attributive'' sense, an entity is good in relation to a certain kind.", "For example, a person with a clear voice may be a good singer or a knife with a blunt edge may be a bad knife.", "But this still leaves it open whether the entity in question is good or bad in an ''unqualified'' or ''predicative'' sense.", "For example, a person may be a bad assassin but being bad as an assassin is not bad in a predicative sense.", "Axiology is usually interested in the predicative sense of goodness.", "But some philosophers deny that such a sense exists and therefore hold that all value is relative to a kind.A second important distinction is that between ''being good for a person'' and ''being good for the world''.", "''Being good for a person'' or ''prudential value'' has to do with this person's welfare or well-being.", "But what is good for one person may be bad for another person.", "For example, having a dry summer may be good for the hiker in virtue of the pleasant hiking conditions, but bad for the farmer, whose crop is dying because of a lack of water.", "In such cases, the question arises as to what is ''good for the world'' or ''good simpliciter''.", "Utilitarians can solve this problem by defining the ''good for the world'' as the sum of the ''good for each persons''.Philosophers often distinguish between ''evaluative concepts'' (like ''good'' or ''bad'') and ''deontic concepts'' (like ''right'', ''fitting'' or ''ought'').", "The former belong to axiology proper and express what has worth or value while the latter belong to ethics (and related fields) and express what one ought to do.", "Philosophers have tried to provide a unified account of these two fields since they seem to be intimately related.", "Consequentialists see evaluative concepts as fundamental and define deontic concepts in terms of evaluative concepts.", "''Fitting-attitude theories'', on the other hand, try to reduce evaluative concepts to deontic concepts.", "''Consequentialism'' is an ethical theory that holds that, given a certain set of possible actions, we ought to perform the action that has the best overall consequences.", "So what we ought to do is defined in evaluative terms: whatever leads to the consequences with the highest value.", "''Fitting-attitude theories'' are axiological theories that define the value of something in terms of the attitude that would be ''fitting'' to have towards this thing, for example, that it would be good to find a cure for cancer because this would be a fitting object of desire.", "These accounts build on the deontic notion that some of our attitudes towards the world are ''fitting'' or ''right'' to define what is ''good''." ], [ "See also",

scandalous.", "The covenant of marriage was considered holy, and to portray it as Ibsen did was controversial.", "However, the Irish playwright George Bernard Shaw found Ibsen's willingness to examine society without prejudice exhilarating.The Swedish playwright August Strindberg criticised the play in his volume of essays and short stories ''Getting Married'' (1884).", "Strindberg questioned Nora's walking out and leaving her children behind with a man that she herself disapproved of so much that she would not remain with him.", "Strindberg also considers that Nora's involvement with an illegal financial fraud that involved Nora forging a signature, all done behind her husband's back, and then Nora's lying to her husband regarding Krogstad's blackmail, are serious crimes that should raise questions at the end of the play, when Nora is moralistically judging her husband.", "And Strindberg points out that Nora's complaint that she and Torvald \"have never exchanged one serious word about serious things,\" is contradicted by the discussions that occur in act one and two.The reasons Nora leaves her husband are complex, and various details are hinted at throughout the play.", "In the last scene, she tells her husband she has been \"greatly wronged\" by his disparaging and condescending treatment of her, and his attitude towards her in their marriage – as though she were his \"doll wife\" — and the children in turn have become her \"dolls,\" leading her to doubt her own qualifications to raise her children.", "She is troubled by her husband's behavior in regard to the scandal of the loaned money.", "She does not love her husband, she feels they are strangers, she feels completely confused, and suggests that her issues are shared by many women.", "George Bernard Shaw suggests that she left to begin \"a journey in search of self-respect and apprenticeship to life,\" and that her revolt is \"the end of a chapter of human history.", "\"Michael Meyer argued that the play's theme is not women's rights, but rather \"the need of every individual to find out the kind of person he or she really is and to strive to become that person.\"", "In a speech given to the Norwegian Association for Women's Rights in 1898, Ibsen insisted that he \"must disclaim the honor of having consciously worked for the women's rights movement,\" since he wrote \"without any conscious thought of making propaganda,\" his task having been \"the ''description of humanity''.\"", "However, the play is associated with feminism, as Miriam Schneir includes it in her anthology ''Feminism: The Essential Historical Writings'', labelling it as one of the essential feminist works.Because of the departure from traditional behavior and theatrical convention involved in Nora's leaving home, her act of slamming the door as she leaves has come to represent the play itself.", "In ''Iconoclasts'' (1905), James Huneker noted \"That slammed door reverberated across the roof of

[ [ "AIM-7 Sparrow" ], [ "Introduction", "The '''AIM-7 Sparrow''' (Air Intercept Missile) is an American medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, United States Marine Corps, and various other air forces and navies.", "Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s.", "It remains in service, although it is being phased out in aviation applications in favor of the more advanced AIM-120 AMRAAM.The early Sparrow was intended primarily for use against larger targets, especially bombers, and had numerous operational limitations in other uses.", "Against smaller targets, the need to receive a strong reflected radar signal made it difficult to achieve lock-on at the missile's effective range.", "As the launching aircraft's own radar needed to be pointed at the target throughout the engagement, this meant that in fighter-vs-fighter combat the enemy fighter would often approach within the range of shorter-range infrared homing missiles while the launching aircraft had to continue flying towards its target.", "Additionally, early models were only effective against targets at roughly the same or higher altitudes, below which reflections from the ground became a problem.A number of upgraded Sparrow designs were developed to address these issues.", "In the early 1970s, the RAF developed the Skyflash version with an inverse monopulse seeker and improved motor, while the Italian Air Force introduced the similar Aspide.", "Both could be fired at targets below the launching fighter (\"look-down, shoot down\"), were more resistant to countermeasures, and were much more accurate in the terminal phase.", "This basic concept then became part of the US Sparrows in the M model (for monopulse) and some of these were later updated as the P model, the last to be produced in the US.", "Aspides sold to China resulted in the locally produced PL-11.The Japan Self-Defense Forces also employ the Sparrow missile, though it is being phased out and replaced by the Mitsubishi AAM-4.The Sparrow was also used as the basis for a surface-to-air missile, the RIM-7 Sea Sparrow, used by a number of navies for air defense.", "Fired at low altitude and flying directly at its target, though, the range of the missile in this role is greatly reduced because of the higher air density of the lower atmosphere.", "With the retirement of the Sparrow in the air-to-air role, a new version of the Sea Sparrow was produced to address this concern, producing the larger and more capable RIM-162 ESSM." ], [ "Development", "===Sparrow I===Sparrow I's during tests on a Douglas F3D Skyknight in the early 1950sThe Sparrow emerged from a late-1940s United States Navy program to develop a guided rocket weapon for air-to-air use.", "In 1947 the Navy contracted Sperry to build a beam-riding version of a standard HVAR, the standard unguided aerial rocket, under '''Project Hotshot'''.", "The weapon was initially dubbed '''KAS-1''', then '''AAM-2''', and — from 1948 on — '''AAM-N-2'''.", "The airframe was developed by the Douglas Aircraft Company.", "The diameter of the HVAR proved to be inadequate for the electronics, leading Douglas to expand the missile's airframe to diameter.", "The prototype weapon began unpowered flight tests in 1947, and made its first aerial interception in 1952.After a protracted development cycle the initial '''AAM-N-2 Sparrow''' entered limited operational service in 1954 with specially modified Douglas F3D Skyknight all-weather carrier night fighters.", "In 1956, they were joined by the McDonnell F3H-2M Demon and Vought F7U Cutlass fighter aircraft.", "Compared to the modern versions, the Sparrow I was more streamlined and featured a bullet-shaped airframe with a long pointed nose.Sparrow I was a limited and rather primitive weapon.", "The limitations of beam-riding guidance (which was slaved to an optical sight on single-seater fighters and to radar on night fighters) restricted the missile to attacks against targets flying a straight course and made it essentially useless against a maneuvering target.", "Only about 2,000 rounds were produced to this standard.===Sparrow II===Sparrow 2 MissileAs early as 1950 Douglas examined equipping the Sparrow with an active radar seeker, initially known as '''XAAM-N-2a ''Sparrow II''''', the original retroactively becoming '''''Sparrow I'''''.", "In 1952 it was given the new code '''AAM-N-3'''.", "The active radar made the Sparrow II a \"fire and forget\" weapon, allowing several to be fired at separate targets at the same time.By 1955 Douglas proposed going ahead with development, intending it to be the primary weapon for the F5D Skylancer interceptor.", "It was later selected, with some controversy, to be the primary weapon for the Canadian Avro Arrow supersonic interceptor, along with the new Astra fire-control system.", "For Canadian use and as a second source for US missiles, Canadair was selected to build the missiles in Quebec.The small size of the missile forebody and the K-band AN/APQ-64-radar limited performance, and it was never able to work in testing.", "After considerable development and test firings in the U.S. and Canada, Douglas abandoned development in 1956.Canadair continued development until the Arrow was cancelled in 1959.===Sparrow X===A subvariant of the Sparrow I armed with the same nuclear warhead as the MB-1 Genie was proposed in 1958 but was cancelled shortly thereafter.===Sparrow III===F3H Demon launching a Sparrow III in 1958Concurrently with the development of the Sparrow I, in 1951 Raytheon began work on a semi-active radar-homing version, the '''AAM-N-6 ''Sparrow III'''''.", "The first of these weapons entered United States Navy service in 1958.The '''AAM-N-6a''' was similar to the -6, but used a new Thiokol liquid-fuel rocket engine for improved performance.", "It also included changes to the guidance electronics to make it effective at higher closing speeds.", "The -6a was also selected to arm the Air Force's ''F-110A Spectre'' (F-4 Phantom) fighters in 1962, known to them as the '''AIM-101'''.", "It entered production in 1959, with 7500 being built.With a reversion to a Rocketdyne solid-fuel motor, the '''AAM-N-6b''' started production in 1963.The new motor significantly increased the maximum range to for head-on attacks.During this year the Air Force and Navy agreed on standardized naming conventions for their missiles.", "The Sparrows became the AIM-7 series.", "The original Sparrow I and aborted Sparrow II became the '''AIM-7A''' and '''AIM-7B''', despite both being out of service.", "The -6, -6a, and -6b became the '''AIM-7C''', '''AIM-7D''', and '''AIM-7E''' respectively.25,000 AIM-7Es were produced and saw extensive use during the Vietnam War, where its performance was considered disappointing.", "The mixed results were a combination of reliability problems (exacerbated by the tropical climate), limited pilot training in fighter-to-fighter combat, and restrictive rules of engagement that generally prohibited BVR (beyond visual range) engagements.", "The Pk (kill probability) of the AIM-7E was less than 10%; US fighter pilots shot down 59 aircraft out of the 612 Sparrows fired.", "Of the 612 AIM-7D/E/E-2 missiles fired, 97 (or 15.8%) hit their targets, resulting in 56 (or 9.2%) kills.", "Two kills were obtained beyond visual range.In 1969 an improved version, the E-2, was introduced with clipped wings and various changes to the fuzing.", "Considered a \"dogfight Sparrow\", the AIM-7E-2 was intended to be used at shorter ranges where the missile was still travelling at high speeds, and in the head-on aspect, making it much more useful in the visual limitations imposed on the engagements.", "Even so, its kill rate was only 13% in combat, leading to a practice of ripple-firing all four at once in hopes of increasing kill probability.", "Its worst tendency was to detonate prematurely about 1,000 feet ahead of the launching aircraft, but it also had many motor failures, erratic flights, and fuzing problems.", "An E-3 version included additional changes to the fuzing, and the E-4 featured a modified seeker for use with the F-14 Tomcat.===Vietnam War

this version had room for improvement, leading British Aerospace and the Italian firm Alenia to develop advanced versions of Sparrow with better performance and improved electronics as the BAe Skyflash and Alenia Aspide, respectively.The most common version of the Sparrow today, the '''AIM-7M''', entered service in 1982 and featured a new inverse monopulse seeker (matching the capabilities of Skyflash), active radar proximity fuse, digital controls, improved ECM resistance, and better low-altitude performance.", "It was used to good advantage in the 1991 Gulf War, where it scored many USAF air-to-air kills.", "Of 44 missiles fired, 30 (68.2%) hit their intended targets resulting in 24/26 (54.5%/59.1%) kills.", "19 kills were obtained beyond visual range.The '''AIM-7P''' is similar in most ways to the M versions, and was primarily an upgrade for existing M-series missiles.", "Changes were mainly to the software, improving low-level performance.", "A follow-on Block II upgrade added a new rear receiver allowing the missile to receive mid-course correction from the launching aircraft.", "Plans initially called for all M versions to be upgraded, but currently P's are being issued as required to replace M's lost or removed from the inventory.The final version of the missile was to have been the '''AIM-7R''', which added an infrared homing seeker to an otherwise unchanged AIM-7P Block II.", "A general wind-down of the budget led to it being cancelled in 1997.The Sparrow is now being phased out with the availability of the active-radar AIM-120 AMRAAM, but is likely to

partnered with Douglas Aircraft Company in the development of the Sparrow II (AAM-N-3/AIM-7B).", "After Douglas dropped out of this program, Canadair continued on with it until the termination of the Arrow project.The AAM-N-3 Sparrow II was unique in that it had a fully active radar guidance system.", "This combined both a radar transmitter and receiver in the missile, making it unnecessary for the pilot to keep the aircraft aimed at the target after firing the missile, unlike Semi-active radar homing (SARH) missiles which require continuous radar-assisted guidance throughout flight.", "This allowed the aircraft that fired the AAM-N-3 to turn away, prosecute other targets, and/or escape from potential retaliatory missiles fired by the enemy aircraft during the time it took for the Sparrow to reach its target.", "Despite the significant advantages of this design over SARH guidance, all subsequent models of the Sparrow use semi-active radar homing.To accommodate the active radar guidance system, the AAM-N-3 Sparrow II had a much greater volume than its predecessor.", "Its size would subsequently set the precedent for all future Sparrow variants.In 1959, Canadair had completed five missiles based on airframes from Douglas, and built two models from scratch, when the program was cancelled with the cancellation of the Arrow.===Italy===The Aspide was more heavily modified than

the AIM-7E Sparrow technology from the US, and produced its own version.Later in the 1980s, Alenia started to produce an improved version of the AIM-7 called the Aspide.", "Compared to the AIM-7E, it received an improved new monopulse guidance system that allowed for a better hit ratio and easier targeting of enemies at low altitude with ground-clutter confusion.It also received a new and more powerful engine and new control surfaces.", "These control surfaces were each independent of the others, giving the missile greatly improved maneuverability over the AIM-7E and the English Skyflash that still used dependent control surfaces.===People's Republic of China===The PL-11 and HQ-6 is a family of Chinese missiles developed by the Shanghai Academy of Science and Technology, largely based on the Italian Aspide version of the Sparrow missile.===Soviet Union===The Soviet Union acquired an AIM-7 in 1968 and a Vympel team started copying it as the '''K-25'''.", "The missile did not enter production as the R-23 was thought to have better versatility, range, signal processing logic, and immunity to interference.", "K-25 work ended in 1971, but analysis of the Sparrow was later used to inform the design of the Vympel R-27, particularly the servomechanisms and movable wings.===UK===The Skyflash looked identical to the Sparrow from the outside, but housed a greatly improved seeker and upgraded motor.British Aerospace (BAe) licensed the AIM-7E2 technology in the 1970s, producing the '''Skyflash''' missile.", "Skyflash used a Marconi XJ521 monopulse seeker together with improvements to the electronics.", "It was powered by the Aerojet Mk52 mod 2 rocket engine (later by the Rocketdyne Mk38 mod 4).", "Skyflash entered service with the Royal Air Force (RAF) on their Phantom FG.1/FGR.2 in 1978, and later on the Tornado F3.Skyflash was also exported to Sweden for use on their Viggen fighters.An upgraded version with active radar seeker, called '''Active Sky Flash''', was proposed by BAe and Thomson-CSF, but did not receive funding because the RAF opted for other missiles." ], [ "Design", "The Sparrow has four major sections: guidance section, warhead, control, and rocket motor (currently the Hercules MK-58 solid-propellant rocket motor).", "It has a cylindrical body with four wings at mid-body and four tail fins.", "Although the external dimensions of the Sparrow remained relatively unchanged from model to model, the internal components of newer missiles represent major improvements, with vastly increased capabilities.", "The warhead is of the continuous-rod type.As with other semi-active radar guided missiles, the missile does not generate radar signals, but instead homes in on reflected continuous-wave signals from the launch platform's radar.", "The receiver also senses the guidance radar to enable comparisons that enhance the missile's resistance to passive jamming." ], [ "Principle of guidance", "Close-up of an AN/APM-282 test set computer, for testing AIM-7 missile guidanceThe launching aircraft illuminates the target with its radar.", "In 1950s radars, these were single-target tracking devices using a nutating horn as part of the antenna, thereby sweeping the beam in a small cone.", "Signal processing is applied to determine the direction of maximum illumination, thereby developing a signal to steer the antenna toward the target.", "The missile detects the reflected signal from the target with a high-gain antenna in a similar fashion and steers the entire missile toward closure with the target.", "The missile guidance also samples a portion of the illuminating signal via rearward-pointing waveguides.", "The comparison of these two signals enabled logic circuits to determine the true target reflection signal, even if the target were to eject radar-reflecting chaff." ], [ "Operators", "Map with AIM-7 operators in blue***********************" ], [ "See also", "* List of missiles* 1963 United States Tri-Service

[ [ "AIM-120 AMRAAM" ], [ "Introduction", "The '''AIM-120'''''' Advanced Medium-Range Air-to-Air Missile''' '''(AMRAAM)''' (pronounced /æmɹæm/), is an American beyond-visual-range air-to-air missile capable of all-weather day-and-night operations.", "It uses active transmit-receive radar guidance instead of semi-active receive-only radar guidance.", "When an AMRAAM missile is launched, NATO pilots use the brevity code \"Fox Three\".", "more than 14,000 had been produced for the United States Air Force, the United States Navy, and 33 international customers.", "The AMRAAM has been used in several engagements, achieving 16 air-to-air kills in conflicts over Iraq, Bosnia, Kosovo, India, and Syria." ], [ "Origins", "===AIM-7 Sparrow MRM===The AIM-7 Sparrow medium range missile (MRM) was purchased by the US Navy from original developer Hughes Aircraft in the 1950s as its first operational air-to-air missile with \"beyond visual range\" (BVR) capability.", "With an effective range of about , it was introduced as a radar beam-riding missile and then it was improved to a semi-active radar guided missile which would home in on reflections from a target illuminated by the radar of the launching aircraft.", "It was effective at visual to beyond visual range.", "The early beam riding versions of the Sparrow missiles were integrated onto the McDonnell F3H Demon and Vought F7U Cutlass, but the definitive AIM-7 Sparrow was the primary weapon for the all-weather McDonnell Douglas F-4 Phantom II fighter/interceptor, which lacked an internal gun in its U.S. Navy, U.S. Marine Corps, and early U.S. Air Force versions.", "The F-4 carried up to four AIM-7s in built-in recesses under its belly.Designed for use against non-maneuvering targets such as bombers, the missiles initially performed poorly against fighters over North Vietnam, and were progressively improved until they proved highly effective in dogfights.", "Together with the short-range, infrared-guided AIM-9 Sidewinder, they replaced the AIM-4 Falcon IR and radar guided series for use in air combat by the USAF as well.", "A disadvantage to semi-active homing was that only one target could be illuminated by the launching fighter plane at a time.", "Also, the launching aircraft had to remain pointed in the direction of the target (within the azimuth and elevation of its own radar set) which could be difficult or dangerous in air-to-air combat.An active-radar variant called the Sparrow II was developed to address these drawbacks, but the U.S. Navy pulled out of the project in 1956.The Royal Canadian Air Force, which took over development in the hopes of using the missile to arm their prospective Avro Canada CF-105 Arrow interceptor, soon followed in 1958.The electronics of the time simply could not be miniaturized enough to make Sparrow II a viable working weapon.", "It would take decades, and a new generation of digital electronics, to produce an effective active-radar air-to-air missile as compact as the Sparrow.===AIM-54 Phoenix LRM===The US Navy later developed the AIM-54 Phoenix long-range missile (LRM) for the fleet air defense mission.", "It was a large , Mach 5 missile designed to counter cruise missiles and the bombers that launched them.", "Originally intended for the straight-wing Douglas F6D Missileer and then the navalized General Dynamics–Grumman F-111B, it finally saw service with the Grumman F-14 Tomcat, the only fighter capable of carrying such a heavy missile.", "The Phoenix was the first US fire-and-forget, multiple-launch, radar-guided missile: one which used its own active guidance system to guide itself without help from the launch aircraft when it closed on its target.", "This, in theory, gave a Tomcat with a six-Phoenix load the unprecedented capability of tracking and destroying up to six targets beyond visual range, as far as away—the only US fighter with such capability.A full load of six Phoenix missiles and its dedicated launcher exceeded a typical Vietnam-era bomb load.", "Its service in the US Navy was primarily as a deterrent, as its use was hampered by restrictive rules of engagement in conflicts such as 1991 Gulf War, Southern Watch (enforcing no-fly zones), and Iraq War.", "The US Navy retired the Phoenix in 2004 in light of availability of the AIM-120 AMRAAM on the McDonnell Douglas F/A-18 Hornet and the pending retirement of the F-14 Tomcat from active service in late 2006.===ACEVAL/AIMVAL===The Department of Defense conducted an extensive evaluation of air combat tactics and missile technology from 1974 to 1978 at Nellis AFB using the F-14 Tomcat and F-15 Eagle equipped with Sparrow and Sidewinder missiles as the blue force and aggressor F-5E aircraft equipped with AIM-9L all-aspect Sidewinders as the red force.", "This joint test and evaluation (JT&E) was designated Air Combat Evaluation/Air Intercept Missile Evaluation (ACEVAL/AIMVAL).", "A principal finding was that the necessity to produce illumination for the Sparrow until impact resulted in the red force's being able to launch their all-aspect Sidewinders before impact, resulting in mutual kills.", "What was needed was Phoenix-type multiple-launch and terminal active capability in a Sparrow-size airframe.", "This led to a memorandum of agreement (MOA) with European allies (principally the UK and Germany for development) for the US to develop an advanced, medium-range, air-to-air missile with the USAF as lead service.====ASRAAM====The MOA also saw an agreement to develop a replacement for the Sidewinder, specifically; an advanced ‘dogfight’ air-to-air missile, capable of better covering the range disparity that would emerge between such short-range missiles and the eventual AMRAAM.", "This task fell to a British-German design team, with the Germans leaving the project in 1989.The missile would emerge as the British Advanced Short Range Air-to-Air Missile (ASRAAM), entering service in 1998.While the U.S. never adopted the ASRAAM — instead opting to continue upgrading the Sidewinder — the ASRAAM did enter into service with the British, Indian, and Australian militaries.", "The UK has continued to upgrade the ASRAAM, with the ‘Block 6’ variant entering service in 2022.===Requirements===By the 1990s, the reliability of the Sparrow had improved so much from the dismal days of Vietnam that it accounted for the largest number of aerial targets destroyed in the Desert Storm part of the Gulf War.", "But while the USAF had passed on the Phoenix and its own similar AIM-47 Falcon/Lockheed YF-12 to optimize dogfight performance, it still needed a multiple-launch fire-and-forget capability for the F-15 and F-16.The AMRAAM would need to be fitted on fighters as small as the F-16, and fit in the same spaces that were designed to fit the Sparrow on the F-4 Phantom.", "The European partners needed AMRAAM to be integrated on aircraft as small as the BAe Sea Harrier.", "The US Navy needed the AMRAAM to be carried on the F/A-18 Hornet and wanted capability for two to be carried on a launcher that normally carried one Sparrow to allow for more air-to-ground weapons.", "Finally, the AMRAAM became one of the primary air-to-air weapons of the new Lockheed Martin F-22 Raptor fighter, which needed to place all of its weapons into internal weapons bays in order to help achieve an extremely low radar cross-section." ], [ "Development", "First successful test at the White Sands Missile Range, New Mexico 1982AMRAAM was developed as the result of an agreement (the Family of Weapons MOA, no longer in effect by 1990), among the United States and several other NATO nations to develop air-to-air missiles and to share production technology.", "Under this agreement, the U.S. was to develop the next generation medium range missile (AMRAAM) and Europe would develop the next generation short range missile (ASRAAM).", "Although Europe initially adopted the AMRAAM, an effort to develop the MDBA Meteor, a competitor to AMRAAM, was begun in UK.", "Eventually, the ASRAAM was developed solely by the British, but using another source for its infrared seeker.", "After protracted development, the deployment of AMRAAM (AIM-120A) began in September 1991 in US Air Force McDonnell Douglas F-15 Eagle fighter squadrons.", "The US Navy soon followed (in 1993) in its McDonnell Douglas F/A-18 Hornet squadrons.The Russian Air Force counterpart of AMRAAM is the somewhat similar R-77 (NATO codename AA-12 Adder), sometimes referred to in the West as the \"AMRAAMski\".", "Likewise, France began its own air-to-air missile development with the MICA concept that used a common airframe for separate radar-guided and infrared-guided versions." ], [ "Operational history", "===United States===The AMRAAM was used operationally for the first time on December 27, 1992, when a USAF General Dynamics F-16D Fighting Falcon shot down an Iraqi MiG-25 that violated the southern no-fly-zone.", "This missile had been returned from the flight line as defective a day earlier.", "The AMRAAM gained a second victory in January 1993 when an Iraqi MiG-23 was shot down by a USAF F-16C.On 28 February 1994, a Republika Srpska Air Force J-21 Jastreb aircraft was shot down by a USAF F-16C that was patrolling the UN-imposed no-fly zone over Bosnia.", "In that engagement, at least three other Serbian aircraft were shot down by USAF F-16Cs using AIM-9 missiles (Banja Luka incident).", "At that point, three launches in combat had resulted in three kills, resulting in the AMRAAM's being informally named \"slammer\" in the second half of the 1990s.In 1994, two USAF F-15 fighters patrolling Iraq's Northern No-Fly Zone mistook a pair of US Army Black Hawk helicopters for Iraqi helicopters, and shot them down.", "One was downed with an AIM-120, and one with an AIM-9 Sidewinder.In 1998 and 1999 AMRAAMs were again fired by USAF F-15 fighters at Iraqi aircraft violating the No-Fly-Zone, but this time they failed to hit their targets.", "During spring 1999, AMRAAMs saw their main combat action during Operation Allied Force, the Kosovo bombing campaign.", "Six Serbian MiG-29s were shot down by NATO (four USAF F-15Cs, one USAF F-16C, and one Dutch F-16A MLU), all of them using AIM-120 missiles (the supposed kill by the F-16C may have actually been friendly fire, a man-portable SA-7 fired by Serbian infantry).On 18 June 2017, a US Boeing F/A-18E Super Hornet engaged and shot down a Sukhoi Su-22 of the Syrian Air Force over northern Syria, using an AIM-120.An AIM-9X Sidewinder had failed to bring down the Syrian jet.", "Some sources have claimed the AIM-9X was decoyed by flares, although the F/A-18E pilot, Lieutenant Commander Michael \"MOB\" Tremel stated it was unclear why the AIM-9X failed, mentioning no use of flares by the Su-22, saying \"I lost the smoke trail, and I have no idea what happened to the missile at that point\".===Türkiye===On 23 March 2014 a Turkish Air Force F-16 from 182 Squadron shot down a Syrian Arab Air Force MiG-23BN with an AIM-120C-7.On 24 November 2015 a Turkish Air Force F-16 shot down a Russian Su-24M strike aircraft with an AIM-120 missile over northern Syria after it allegedly crossed into Turkish airspace.On 1 March 2020, Turkish Air Force F-16s downed two Su-24s belonging to the Syrian Air Force using two AIM-120C-7s.On 3 March 2020, a Syrian Air Force L-39 was shot down over Idlib by Turkish Air Force F-16s from inside Turkish airspace with AIM-120C-7 at a distance of about .", "As of 2020, this has been the longest range AIM-120 kill.===Pakistan===On 27 February 2019, India stated that Pakistan Air Force (PAF) used AMRAAMs during Operation Swift Retort.", "Indian officials displayed fragments of an alleged AIM-120C-5 missile as a proof of its usage during the engagement.", "The only confirmed loss of the engagement was an Indian Air Force MiG-21, while Pakistan said it also shot down an Su-30MKI Flanker-H. IAF officials denied any loss of Su-30 MKI and also told Indian media that an IAF Sukhoi Su-30MKI had dodged and jammed 3-4 AMRAAMs during the dogfight.===Saudi Arabia===During the Yemeni War, Saudi Arabia extensively used F-15 and Typhoon aircraft together with Patriot batteries to intercept and down Yemeni drones and missiles.", "In November 2021, a possible Foreign Military Sales contract was notified to the US Congress regarding the provision to Saudi Arabia for a mix of 280 AIM-120C-7 and C-8 missiles and related support equipment and service that would be used on Saudi F-15 and Typhoon aircraft.", "The deal was required to replenish Saudi missiles stock, running low due to extensive use of AMRAAMs and Patriots against Yemeni missiles and drones.===Spain===On 7 August 2018, a Spanish Air Force Eurofighter Typhoon accidentally launched a missile in Estonia.", "There were no human casualties, but a ten-day search operation for the missile was unsuccessful." ], [ "Effectiveness", "The kill probability (Pk) is determined by several factors, including aspect (head-on interception, side-on or tail-chase), altitude, the speed of the missile and the target, and how hard the target can turn.", "Typically, if the missile has sufficient energy during the terminal phase, which comes from being launched at close range to the target from an aircraft with an altitude and speed advantage, it will have a good chance of success.", "This chance drops as the missile is fired at longer ranges as it runs out of overtake speed at long ranges, and if the target can force the missile to turn it might bleed off enough speed that it can no longer chase the target.", "Operationally, the missile, which was designed for beyond visual range combat, has a Pk of 0.59.The targets included six MiG-29s, a MiG-25, a MiG-23, two Su-22s, a Galeb, and a US Army Blackhawk that was targeted by mistake." ], [ "Operational features summary", "AMRAAM has an all-weather, beyond-visual-range (BVR) capability.", "It improves the aerial combat capabilities of US and allied aircraft to meet the threat of enemy air-to-air weapons as they existed in 1991.AMRAAM serves as a follow-on to the AIM-7 Sparrow missile series.", "The new missile is faster, smaller, and lighter, and has improved capabilities against low-altitude targets.", "It also incorporates a datalink to guide the missile to a point where its active radar turns on and makes terminal intercept of the target.", "An inertial reference unit and micro-computer system makes the missile less dependent upon the fire-control system of the aircraft.Once the missile closes in on the target, its active radar guides it to intercept.", "This feature, known as \"fire-and-forget\", frees the aircrew from the need to further provide guidance, enabling the aircrew to aim and fire several missiles simultaneously at multiple targets and break a radar lock after the missile seeker goes active and guide themselves to the targets.The missile also features the ability to \"Home on Jamming,\" giving it the ability to switch over from active radar homing to passive homing – homing on jamming signals from the target aircraft.", "Software on board the missile allows it to detect if it is being jammed, and guide on its target using the proper guidance system." ], [ "Guidance system overview", " ===Interception course stage===Grumman F-14 Tomcat carrying an AMRAAM during a 1982 testAMRAAM uses two-stage guidance when fired at long range.The aircraft passes data to the missile just before launch, giving it information about the location of the target aircraft from the launch point, including its direction and speed.", "This information is generally obtained using the launching aircraft's radar, although it could come from an infrared search and track system, from another fighter aircraft via a data link, or from an AWACS aircraft.", "Using its built-in inertial navigation system (INS), the missile uses the information provided pre-launch to fly on an interception course toward the target.After launch, if the firing aircraft or surrogate continues to track the target, periodic updates, e.g.", "changes in the target's direction and speed, are sent from the launch aircraft to the missile, allowing the missile to adjust its course, via actuation of the rear fins, so that it is able to close to a self-homing distance where it will be close enough to \"catch\" the target aircraft in the ''basket'' (the missile's radar field of view in which it will be able to lock onto the target aircraft, unassisted by the launch aircraft).Not all armed services using the AMRAAM have elected to purchase the mid-course update option, which limits AMRAAM's effectiveness in some scenarios.", "The RAF initially opted not to use mid-course update for its Tornado F3 force, only to discover that without it, testing proved the AMRAAM was less effective in beyond visual range (BVR) engagements than the older semi-active radar homing BAE Skyflash (a development of the Sparrow), since the AIM-120's own radar is necessarily of lesser range and power as compared to that of the launch aircraft.===Terminal stage and impact===Once the missile closes to self-homing distance, it turns on its active radar seeker and searches for the target aircraft.", "If the target is in or near the expected location, the missile will find it and guide itself to the target from this point.", "If the missile is fired at short range, within visual range (WVR) or the near BVR, it can use its active seeker just after launch to guide it to intercept.===Boresight Visual mode===Apart from the radar-slaved mode, there is a free guidance mode, called \"Visual\".", "This mode is host-aircraft radar guidance-free—the missile just fires and locks onto the first thing it sees.", "This mode can be used for defensive shots, i.e.", "when the enemy has numerical superiority." ], [ "Variants and upgrades", "An AIM-120 AMRAAM missile on display at the U.S. National Air and Space MuseumAIM-120 AMRAAM (right) fitted in a weapons bay of a F-22 Raptor===Air-to-air missile versions===There are currently four main variants of AMRAAM, all in service with the United States Air Force, United States Navy, and the United States Marine Corps.", "The '''AIM-120A''' is no longer in production and shares the enlarged wings and fins with the successor '''AIM-120B'''.", "The AIM-120C has smaller \"clipped\" aerosurfaces to enable internal carriage on the USAF F-22 Raptor.", "AIM-120B deliveries began in 1994.The '''AIM-120C''' deliveries began in 1996.The C-variant has been steadily upgraded since it was introduced.", "The AIM-120C-6 contained an improved fuze (Target Detection Device) compared to its predecessor.", "The AIM-120C-7 development began in 1998 and included improvements in homing and greater range (actual amount of improvement unspecified).", "It was successfully tested in 2003 and is currently being produced for both domestic and foreign customers.", "It helped the U.S. Navy replace the F-14 Tomcats with F/A-18E/F Super Hornets – the loss of the F-14's long-range AIM-54 Phoenix missiles (already retired) is offset with a longer-range AMRAAM-D.", "The lighter weight of the enhanced AMRAAM enables an F/A-18E/F pilot greater bring-back weight upon carrier landings.The '''AIM-120D''' is an upgraded version of the AMRAAM with improvements in almost all areas, including 50% greater range (than the already-extended range AIM-120C-7) and better guidance over its entire flight envelope yielding an improved kill probability (Pk).", "Initial production began in 2006 under the Engineering and Manufacturing Development phase of program testing and ceased in September 2009.Raytheon began testing the D model on August 5, 2008, the company reported that an AIM-120D launched from an F/A-18F Super Hornet passed within lethal distance of a QF-4 target drone at the White Sands Missile Range.", "The range of the AIM-120D is classified, but is thought to extend to about .The AIM-120D (P3I Phase 4) is a development of the AIM-120C with a two-way data link, more accurate navigation using a GPS-enhanced IMU, an expanded no-escape envelope, improved HOBS (high off-boresight) capability, and a max speed of Mach 4.The AIM-120D is a joint USAF/USN project for which Follow-on Operational Test and Evaluation (FOT&E) was completed in 2014.The USN was scheduled to field it from 2014, and AIM-120D will be carried by all Pacific carrier groups by 2020, although the 2013 sequestration cuts could push back this later date to 2022.The Royal Australian Air Force requested 450 AIM-120D missiles, which would make it the first foreign operator of the missile.", "The procurement, approved by the US Government in April 2016, will cost $1.1 billion and will be integrated for use on the F/A-18F Super Hornet, EA-18G Growler and the F-35 Lightning II aircraft.There were also plans for Raytheon to develop a ramjet-powered derivative of the AMRAAM, the Future Medium Range Air-Air Missile (FMRAAM).", "The FMRAAM was not produced since the target market, the British Ministry of Defence, chose the Meteor missile over the FMRAAM for a BVR missile for the Eurofighter Typhoon aircraft.Raytheon is also working with the Missile Defense Agency to develop the Network Centric Airborne Defense Element (NCADE), an anti-ballistic missile derived from the AIM-120.This weapon will be equipped with a ramjet engine and an infrared homing seeker derived from the Sidewinder missile.", "In place of a proximity-fuzed warhead, the NCADE will use a kinetic energy hit-to-kill vehicle based on the one used in the Navy's RIM-161 Standard Missile 3.The -120A and -120B models are currently nearing the end of their service life while the -120D variant achieved initial operational capability in 2015.AMRAAM was due to be replaced by the USAF, the U.S. Navy, and the U.S. Marine Corps after 2020 by the Joint Dual Role Air Dominance Missile (Next Generation Missile), but it was terminated in the 2013 budget plan.", "Exploratory work was started in 2017 on a replacement called Long-Range Engagement Weapon.In 2017, work on the AIM-260 Joint Advanced Tactical Missile (JATM) began to create a longer-ranged replacement for the AMRAAM to contend with foreign weapons like the Chinese PL-15.Flight tests are planned to begin in 2021 and initial operational capability is slated for 2022, facilitating the end of AMRAAM production by 2026.In July 2022, Raytheon announced the AIM-120D-3 became the longest-range variant in testing, as well as an air-launched adaptation of the NASAMS-based AMRAAM-ER called the '''AMRAAM-AXE''' (air-launched extended envelope).", "The development of AIM-120D-3 and AMRAAM-AXE is likely driven by the PL-15 performance.", "The AIM-120D-3 and the AIM-120C-8 variant for international customers were developed under the Form, Fit, Function Refresh (F3R) program and feature 15 upgraded circuit cards in the missile guidance section and the capability to continuously upgrade future software enhancements.", "All AMRAAMs planned for production are either the AIM-120D-3 or the AIM-120C-8 incorporating F3R functionality as of April 2023.===Ground-launched systems===NASAMS launcherAIM-9X on HMMWVThe Norwegian Advanced Surface-to-Air Missile System (NASAMS), developed by Kongsberg Defence & Aerospace and fielded in 1994-1995, consists of a number of towed batteries (containing six AMRAAM launching canisters with integrated launching rails) along with separate radar trucks and control station vehicles.The US Marine Corps and the US Army tested launching AMRAAM missiles from a six-rail carrier on HMMWV as part of their CLAWS (Complementary Low-Attitude Weapon System) and SLAMRAAM (Surface Launched AMRAAM) programs, which were canceled due to budgetary cuts.", "A more recent version is the ''High Mobility Launcher'' for the NASAMS, made in cooperation with Raytheon (Kongsberg Defence & Aerospace was already a subcontractor on the SLAMRAAM system), where the launch-vehicle is a Humvee (M1152A1 HMMWV), containing four AMRAAMs and two optional AIM-9X Sidewinder missiles.==== AMRAAM-ER ====AMRAAM-ER displayed at Paris Air Show 2007As part of the SLAMRAAM project, Raytheon offered the Extended Range upgrade to surface-launched AMRAAM, called AMRAAM-ER.", "The missile is an Evolved Sea Sparrow Missile using AMRAAM head with two-stage guidance system.", "It was first shown at the Paris Air Show 2007 and was test-fired in 2008.Following the cancellation of SLAMRAAM funding in 2011, development of the NASAMS version restarted in 2014.in February 2015 Raytheon announced the AMRAAM-ER missile option for NASAMS, with expected production in 2019, and the first flight test took place in August 2016.Engagement envelope was expanded with a 50 percent increase in maximum range and 70 percent increase in maximum altitude.In 2019 Qatar placed an order for AMRAAM-ER missiles as part of a NASAMS purchase.The missile was testfired at Andøya Space Center in May 2021.Raytheon has proposed an air-launched adaptation of the missile called AMRAAM-AXE, from \"Air-launched Extended Envelope\"." ], [ "Foreign sales", "Canadair, now Bombardier, had largely helped with the development of the AIM-7 Sparrow and Sparrow II, and assisted to a lesser extent in the AIM-120 development.", "In 2003, the RCAF placed an order for 97 AIM-120C-5 and later C-7 missiles.", "These missiles have been in service on the CF-18 Hornet since 2004, and fully replaced the AIM-7 Sparrow in the 2010s.", "In 2020, the Canadian Government was approved by the U.S DoD for 32 advanced AIM-120D missiles to

[ [ "AGM-88 HARM" ], [ "Introduction", "The '''AGM-88 HARM''' (High-speed Anti-Radiation Missile) is a tactical, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems.", "It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system.", "Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments." ], [ "Description", "The AGM-88 can detect, attack and destroy a radar antenna or transmitter with minimal aircrew input.", "The proportional guidance system that homes in on enemy radar emissions has a fixed antenna and seeker head in the missile's nose.", "A smokeless, solid-propellant, booster-sustainer rocket motor propels the missile at speeds over Mach 2.The HARM was a missile program led by the U.S. Navy, and it was first carried by the A-6E, A-7, and F/A-18A/B aircraft, and then it equipped the EA-6B and EA-18G dedicated electronic attack aircraft.", "RDT&E for use on the F-14 aircraft was begun, but not completed.", "The U.S. Air Force (USAF) put the HARM onto the F-4G Wild Weasel aircraft, and later on specialized F-16s equipped with the HARM Targeting System (HTS).", "The missile has three operational modes: Pre-Briefed (PB), Target Of Opportunity (TOO) and Self-Protect (SP).", "The HTS pod, used by the USAF only, allows F-16s to detect and automatically target radar systems with HARMs instead of relying on the missile's sensors alone." ], [ "History", "===Deployment=======United States====The HARM missile was approved for full production in March 1983, obtained initial operating capability (IOC) on the A-7E Corsair II in late 1983 and then deployed in late 1985 with VA-46 aboard the aircraft carrier USS ''America''.", "In 1986, the first successful firing of the HARM from an EA-6B was performed by VAQ-131.It was soon used in combat—in March 1986 against a Libyan S-200 surface to air missiles site in the Gulf of Sidra, and then during Operation Eldorado Canyon in April.HARM was used extensively by the Navy, Marine Corps, and the Air Force in Operation Desert Storm during the Persian Gulf War of 1991.During the Gulf War, the HARM was involved in a friendly fire incident when the pilot of an F-4G Wild Weasel escorting a B-52G bomber mistook the latter's tail gun radar for an Iraqi AAA site—this was after the tail gunner of the B-52 had targeted the F-4G, mistaking it for an Iraqi MiG.", "The F-4 pilot launched the missile and then saw that the target was the B-52, which was hit.", "It survived with shrapnel damage to the tail and no casualties.", "The B-52 (serial number 58-0248) was subsequently renamed ''In HARM's Way''.", "\"Magnum\" is spoken over the radio to announce the launch of an AGM-88.During the Gulf War, if an aircraft was illuminated by enemy radar a bogus \"Magnum\" call on the radio was often enough to convince the operators to power down.", "This technique would also be employed in Yugoslavia during air operations in 1999.On 28 April 1999, during this campaign, an early variant of the AGM-88, after being fired in self defense mode by a NATO jet, lost its radio frequency track as the Serbian air defense radar was turned off, hitting a house in the Gorna Banya district of the Bulgarian capital, Sofia, causing damages, but no casualties.During the 1990s and early 2000s and during the initial weeks of the operation Iraqi Freedom, the HARM was used to enforce the Iraqi No-Fly-Zones, degrading the Iraqi air defenses trying to engage US and allied patrolling aircraft.During the opening days of Operation Iraqi Freedom, deconflicting US Army Patriot batteries and allied aircraft routes turned out being more difficult than expected, resulting in three major friendly fire incidents: in one of them, on March 24, 2003, a USAF F-16CJ Fighting Falcon fired an AGM-88 HARM at a Patriot missile battery after the Patriot's radar had locked onto and prepared to fire at the aircraft, causing the pilot to mistake it for an Iraqi surface-to-air missile system because the aircraft was in air combat operations and was on its way to a mission near Baghdad.", "The HARM damaged the Patriot's radar system with no casualties.Starting in March 2011, during Operation Unified Protector against Libya, US Navy EA-18Gs had their combat debut using HARMs against Libyan air defenses together with USAF F-16CJs and Italian Tornadoes.====Israel====In 2013, US President Obama offered the AGM-88 to Israel for the first time.====Italy====Starting in March 2011, during Operation Unified Protector, Italian Tornados employed AGM-88 HARMs against Libyan air defenses.====Ukraine====In mid-2022, during the Russian invasion of Ukraine, the US supplied AGM-88 HARM missiles to Ukraine.", "It was only disclosed after Russian forces showed footage of a tail fin from one of these missiles in early August 2022.U.S.", "Under Secretary of Defense for Policy Colin Kahl said in recent aid packages they had included a number of anti-radiation missiles that can be fired by Ukrainian aircraft.", "As built, Soviet-era aircraft do not have the computer architecture to accept NATO standard weapons.", "Indeed, none of the former Warsaw Pact countries, even those that have had their Soviet-era aircraft updated, were enabled to fire a HARM before.", "The interface seemed difficult unless using a \"crude modification\", such as integrating it with an added e-tablet into the cockpit, building a nearly totally independent subsystem within the carrying aircraft.", "As suggested by Domenic Nicholis, defense correspondent for the Telegraph in the UK, the HARM missile is possibly operating in one of its three modes that enables it to find its target once flying after being released towards a possible enemy air defense and electronic emission area.", "Pre mission or during flight, NATO signals intelligence aircraft or different intelligence would be providing the overall electromagnetic emissions battlefield to locate the Russian radars where the Ukrainian jets, armed with HARMs would be directed to fire them.", "This allows the missile to achieve a very long range attack profile, even if it's possible that the missile does not find a target while flying, going wasted.", "A second possible use of the HARM is operating it in a mode called \"HARM as sensor\".", "Similar to the described mode before, the missile acts as both sensor and weapon, not requiring a sensor pod.", "A simple interface would show that the missile has a target and the pilot can launch it.", "In this way the range is shorter, and the jet could be under threat already, but would maximize the possibility to hit the emitter.In August 2022, a senior U.S. defense official confirmed that the Ukrainians have successfully integrated the AGM-88 HARM missile onto their \"MiG aircraft\", hinting the MiG-29 was the chosen fighter jet with video evidence of AGM-88 missiles fired by upgraded Ukrainian MiG-29s released by the Ukrainian Air Force a few days later.Speaking on 19 September, US Air Force General James B. Hecker said the effort to integrate AGM-88 HARM missiles into the Ukrainian Su-27s and MiG-29s took \"some months\" to achieve.", "This does not give the Ukrainian Air Force the same \"capabilities that it would on an F-16.\"", "However he said: \"Even though you don't get a kinetic kill ... you can get local air superiority for a period of time where you can do what you need to do.", "\"During early September 2022, a Ukrainian Su-27S was spotted with an AGM-88 HARM fitted on the wing pylons.", "This is the first case of an Su-27 being spotted with an AGM-88 fitted.", "The missile has been directly fitted to the APU-470 missile launchers, the same launcher used by MiG-29 and Su-27 to fire missiles like the R-27 (air-to-air missile).", "This suggests that mounting the missile on Soviet aircraft is much easier than experts initially believed.", "Being as simple as \"requiring just an interface for the different wirings and the hanging points of the missile\".", "The earlier footage of a Ukrainian MiG-29 using an AGM-88 indicated that the display recognized the missile as a R-27EP, which is designed to lock onto airborne radars.", "This suggests that the aircraft are using their own avionics to fire the missile, without the need for additional modifications.In December, the Ukrainian Air Force released a video showing a MiG-29 firing two HARM missiles in a volley.", "Russia has made the first claim of the war that they have shot down four HARM missiles." ], [ "Variants", "===AGM-88E AARGM===AGM-88E Advanced Antiradiation Guided Missile (AARGM)The AGM-88E Advanced Antiradiation Guided Missile (AARGM) has an updated guidance section and modified control section, along with the rocket motor and warhead section, wings, and fins from the AGM-88 HARM.", "It utilizes millimeter-wave radar for precise terminal guidance, countering the enemy's radar shut-down capability, and has the ability to transmit images of the target before impact.", "Northrop Grumman took control of the AARGM program after acquiring Orbital ATK in 2018.The AGM-88E is in use by the US Navy, US Marine Corps, Italian Air Force, and German Air Force.In June of 2003, Orbital ATK was awarded a $223m contract to develop the AARGM.", "Subsequently, in November 2005, the Italian Ministry of Defense and the US Department of Defense entered into a memorandum of agreement to jointly fund the project.The U.S. Navy demonstrated the AARGM's capability during Initial Operational Test and Evaluation (IOT&E) in spring 2012 with live firing of 12 missiles.", "Aircrew and maintenance training with live missiles was completed in June.The Navy authorized Full-Rate Production (FRP) of the AARGM in August 2012, with 72 missiles for the Navy and nine for the Italian Air Force to be delivered in 2013.A U.S. Marine Corps F/A-18 Hornet squadron will be the first forward-deployed unit with the AGM-88E.In September 2013, ATK delivered the 100th AARGM to the U.S. Navy.", "The AGM-88E program is on schedule and on budget, with Full Operational Capability (FOC) planned for September 2014.The AGM-88E was designed to improve the effectiveness of legacy HARM variants against fixed and relocatable radar and communications sites, particularly those that would shut down to throw off anti-radiation missiles, by attaching a new seeker to the existing Mach 2-capable rocket motor and warhead section, adding a passive anti-radiation homing receiver, satellite and inertial navigation system, a millimeter-wave radar for terminal guidance, and the ability to beam up images of the target via a satellite link just seconds before impact.This model of the HARM will be integrated onto the F/A-18C/D/E/F, EA-18G, Tornado ECR aircraft, and later on the F-35 (externally).In September 2015, the AGM-88E successfully hit a mobile ship target in a live fire test, demonstrating the missile's ability to use antiradiation homing and millimeter-wave radar to detect, identify, locate, and engage moving targets.In December 2019, the German Air Force ordered the AARGM.", "On August 4, 2020, Northrop Grumman's Alliant Techsystems Operations division, based in Northridge, California, was awarded a $12,190,753 IDIQ contract for AARGM depot sustainment support, guidance section and control section repair, and equipment box test and inspection.", "On August 31, 2020, the same Northrop Grumman division was allocated roughly $80.9 million to develop new technology for the AARGM.===AGM-88F HCSM===Although the US Navy/Marine Corps chose the Orbital ATK-produced AGM-88E AARGM, Raytheon developed its own update of the HARM called the ''AGM-88F HARM Control Section Modification (HCSM)'', tested in conjunction with and ultimately for the US Air Force.", "It incorporates similar upgrade features as the AARGM.", "The Republic of China (Taiwan), Bahrain, and Qatar have purchased AGM-88Bs retrofitted with the HCSM upgrade.=== AGM-88G AARGM-ER ===The Navy's FY 2016 budget included funding for an extended range AARGM-ER that uses the existing guidance system and warhead of the AGM-88E with a solid integrated rocket-ramjet to double the range.", "In September 2016, Orbital ATK unveiled its extended-range AARGM-ER, which incorporates a redesigned control section and rocket motor for twice the range and internal carriage on the Lockheed Martin F-35A and F-35C Lightning II with integration on P-8 Poseidon, F-16 Fighting Falcon and Eurofighter Typhoon planned afterwards; internal carriage on the F-35B is not possible due to internal space limitations.", "The new missile, designated AGM-88G, utilizes the AARGM's warhead and guidance systems in a new airframe that replaces the mid-body wings with aerodynamic strakes along the sides with control surfaces relocated to low-drag tail surfaces and a more powerful propulsion system for greater speed and double the range of its predecessor.", "It weighs and is slightly shorter than earlier variants at in length.The U.S. Navy awarded Orbital ATK a contract for AARGM-ER development in January 2018.The USAF later joined the AARGM-ER program, involved in internal F-35A/C integration work.", "The AARGM-ER received Milestone-C approval in August 2021, and the first low-rate initial production contract was awarded the next month; initial operational capability is planned for 2023.The AARGM-ER completed its first, second, third, fourth and fifth flight tests at the Point Mugu Sea Range in July 2021, January 2022, July 2022, December 2022 and May 2023 respectively.In February 2023, the U.S. Navy began exploring the feasibility of launching the AARGM-ER from ground-based launchers and the P-8 Poseidon.On February 27, 2023, Australia has requested to purchase up to 63 AGM-88G AARGM-ERs.On June 5, 2023, The Netherlands announced the acquisition of the AARGM-ER for the use on their F-35A fleet.On October 23, 2023, Finland has been given permission by U.S. State Department to proceed with purchase of up to 150 AGM-88G AARGM-ERs.===Stand-in Attack Weapon===In May 2022, the USAF awarded contracts to L3Harris Technologies, Lockheed Martin, and Northrop Grumman to begin the first phase of development for the Stand-in Attack Weapon (SiAW).", "While previous HARMs were meant to attack air defense radars, the SiAW will have a broader target set including theater ballistic missile launchers, cruise and anti-ship missile launchers, GPS jamming platforms, and anti-satellite systems.", "It will have a shorter range than standoff weapons, being fired by an aircraft after penetrating enemy airspace.", "The SiAW will fit inside the F-35's internal weapon bays.", "The Air Force plans to have an operational weapon by 2026.Northrop Grumman was chosen to continue development of the SiAW in September 2023." ], [ "Criticism", "* During Operation Allied Force, NATO reportedly fired 743 HARMs during the course of the 78-day campaign, but could confirm the destruction of only 3 of the original 25 SA-6 batteries.", "Over half of the HARMs expended were preemptive targeting shots (PETs), fired at suspected SAM sites, but without a radar to target.", "During the campaign, Serbian SAM sites fired more than 800 SAMs with only 2 NATO aircraft downed, the majority from fixed sites were fired without radar guidance.", "Radars were also forced to operate for only 20 seconds or less to avoid destruction by HARMs.", "According to Benjamin Lambeth, the F-117 that was downed did not have support from HARM-carrying F-16CJ aircraft." ], [ "Operators", "Map with AGM-88 operators in blue.F-16 carrying an

[ [ "AGM-65 Maverick" ], [ "Introduction", "The '''AGM-65 Maverick''' is an air-to-ground missile (AGM) designed for close air support.", "It is the most widely produced precision-guided missile in the Western world, and is effective against a wide range of tactical targets, including armor, air defenses, ships, ground transportation and fuel storage facilities.Development began in 1966 at Hughes Aircraft Company as the first missile to use an electronic contrast seeker.", "It entered service with the United States Air Force in August 1972.Since then, it has been exported to more than 30 countries and is certified on 25 aircraft.", "The Maverick served during the Vietnam, Yom Kippur, Iran–Iraq, and Persian Gulf Wars, along with other smaller conflicts, destroying enemy forces and installations with varying degrees of success.Since its introduction into service, numerous Maverick versions had been designed and produced using electro-optical, laser, and imaging infrared guidance systems.", "The AGM-65 has two types of warhead: one has a contact fuze in the nose, the other has a heavyweight warhead fitted with a delayed-action fuze, which penetrates the target with its kinetic energy before detonating.", "The missile is currently produced by Raytheon Missiles & Defense.The Maverick shares the same configuration as Hughes' AIM-4 Falcon and AIM-54 Phoenix, and measures more than in length and in diameter." ], [ "Development", "The Maverick's development history began in 1965, when the United States Air Force (USAF) began a program to develop a replacement to the AGM-12 Bullpup.", "With a range of , the radio-guided Bullpup was introduced in 1959 and was considered a \"silver bullet\" by operators.", "However, the launch aircraft was required to fly straight towards the target during the missile's flight instead of performing evasive maneuvers, thus endangering itself.", "Even when it hit, the small warhead was only useful against small targets like bunkers; when used against larger targets like the Thanh Hóa Bridge it did little more than char the structure.", "The USAF began a series of projects to replace Bullpup, both larger versions of Bullpup, models C and D, as well as a series of Bullpup adaptations offering fire-and-forget guidance.", "Among the latter were the AGM-83 Bulldog, AGM-79 Blue Eye and AGM-80 Viper.From 1966 to 1968, Hughes Missile Systems Division and Rockwell competed for the contract to build an entirely new fire-and-forget missile with far greater range performance than any of the Bullpup versions.", "Each were allocated $3 million for preliminary design and engineering work of the Maverick in 1966.In 1968, Hughes emerged with the $95 million contract for further development and testing of the missile;

[ [ "AIM-54 Phoenix" ], [ "Introduction", "The '''AIM-54 Phoenix''' is an American radar-guided, long-range air-to-air missile (AAM), carried in clusters of up to six missiles on the Grumman F-14 Tomcat, its only operational launch platform.The Phoenix was the United States' only long-range air-to-air missile.", "The combination of Phoenix missile and the Tomcat's AN/AWG-9 guidance radar meant that it was the first aerial weapons system that could simultaneously engage multiple targets.", "Due to its active radar tracking, the brevity code \"Fox Three\" was used when firing the AIM-54.The act of the missile achieving a radar lock with its own radar is known under brevity as 'Going Pitbull'.Both the missile and the aircraft were used by Iran and the United States Navy.", "In US service both are now retired, the AIM-54 Phoenix in 2004 and the F-14 in 2006.They were replaced by the shorter-range AIM-120 AMRAAM, employed on the F/A-18 Hornet and F/A-18E/F Super Hornet—in its AIM-120D version, the latest version of the AMRAAM just matches the Phoenix's maximum range.The AIM-54 has been used in 62 air-to-air strikes, all by Iran during the eight-year Iran–Iraq War.", "Following the retirement of the F-14 by the U.S. Navy, the weapon's only current operator is the Islamic Republic of Iran Air Force." ], [ "Development", "===Background===Since 1951, the Navy faced the initial threat from the Tupolev Tu-4K 'Bull' carrying anti-ship missiles or nuclear bombs.Eventually, during the height of the Cold War, the threat would have expanded into regimental-size raids of Tu-16 Badger and Tu-22M Backfire bombers equipped with low-flying, long-range, high-speed, nuclear-armed cruise missiles and considerable electronic countermeasures (ECM) of various types.", "This combination was considered capable of saturating fleet defenses and threatening carrier groups.The Navy would require a long-range, long-endurance interceptor aircraft to defend carrier battle groups against this threat.", "The proposed Douglas F6D Missileer was intended to fulfill this mission and oppose the attack as far as possible from the fleet it was defending.", "The weapon needed for interceptor aircraft, the Bendix AAM-N-10 Eagle, was to be an air-to-air missile of unprecedented range when compared to contemporary AIM-7 Sparrow missiles.", "It would work together with Westinghouse AN/APQ-81 radar.", "The Missileer project was cancelled in December 1960.===AIM-54===NA-3A-testbed in 1966In the early 1960s, the U.S. Navy made the next interceptor attempt with the F-111B, and they needed a new missile design.", "At the same time, the USAF canceled the projects for their land-based high-speed interceptor aircraft, the North American XF-108 Rapier and the Lockheed YF-12, and left the capable AIM-47 Falcon missile at a quite advanced stage of development, but with no effective launch platform.The AIM-54 Phoenix, developed for the F-111B fleet air defense fighter, had an airframe with four cruciform fins that was a scaled-up version of the AIM-47.One characteristic of the Missileer ancestry was that the radar sent it mid-course corrections, which allowed the fire control system to \"loft\" the missile up over the target into thinner air where it had better range.The F-111B was canceled in 1968.Its weapons system, the AIM-54 working with the AWG-9 radar, migrated to the new U.S. Navy fighter project, the VFX, which would later become the F-14 Tomcat.The AIM-54 Phoenix was also considered by the Royal Air Force to be used on Avro Vulcan bomber planes as part of an air defence aircraft.", "This missileer conversion would have used 12 missiles onboard and an extensive modification to the Vulcan's radar.In 1977, development of a significantly improved Phoenix version, the AIM-54C, was developed to better counter projected threats from tactical anti-naval aircraft and cruise missiles, and its final upgrade included a re-programmable memory capability to keep pace with emerging ECM." ], [ "Usage in comparison to other weapon systems", "The AIM-54/AWG-9 combination had multiple track (up to 24 targets) and multiple launch (up to six Phoenixes can be launched nearly simultaneously) capability, regardless of weather conditions or heavy enemy electronic warfare, known as jamming.", "The large missile is equipped with a conventional warhead.The AIM-54 is designed for ejection launch, where a pyrotechnic charge forcefully jettisons it from either a LAU-93 or a LAU-132 launcher before its solid propellant rocket motor ignites.On the F-14, four missiles can be carried under the fuselage tunnel attached to special aerodynamic pallets, plus two under glove stations.", "A full load of six Phoenix missiles and the unique launch rails weighs in at over , about twice the weight of Sparrows, putting it above the allowable bringback load (which also would include enough fuel for go-around attempts).", "As such, carrying six Phoenix missiles would necessitate the jettison of at least some of the Phoenix missiles if they were not used.", "The most common air superiority payload was a mix of two Phoenix, three Sparrow, and two Sidewinder missiles.Most other US aircraft relied on the smaller, semi-active medium-range AIM-7 Sparrow.", "Semi-active guidance meant the aircraft no longer had a search capability while supporting the launched Sparrow, reducing situational awareness.The Tomcat's radar could track up to 24 targets in track-while-scan mode, with the AWG-9 selecting up to six potential targets for the missiles.", "The pilot or radar intercept officer (RIO) could then launch the Phoenix missiles once parameters were met.", "The large tactical information display (TID) in the RIO's cockpit gave information to the aircrew (the pilot had the ability to monitor the RIO's display) and the radar could continually search and track multiple targets after Phoenix missiles were launched, thereby maintaining situational awareness of the battlespace.The Link 4 datalink allowed US Navy Tomcats to share information with the E-2C Hawkeye AEW aircraft.", "During Desert Shield in 1990, the Link 4A was introduced; this allowed the Tomcats to have a fighter-to-fighter datalink capability, further enhancing overall situational awareness.", "The F-14D entered service with JTIDS that brought the even better Link 16 datalink \"picture\" to the cockpit.===Active guidance===AIM-54 Phoenix seconds after launch (1989)The Phoenix has several guidance modes and achieves its longest range by using mid-course updates from the F-14A/B AWG-9 radar (APG-71 radar in the F-14D) as it climbs to cruise between and at close to Mach 5.The Phoenix uses this high altitude to maximize its range by reducing atmospheric drag.", "At around from the target, the missile activates its own radar to provide terminal guidance.", "Minimum engagement range for the Phoenix is around ; at this range active homing would initiate upon launch.", "If the AWG-9 radar lost radar lock on a target before the missile had activated its own radar, the missile proceeded on a ballistic trajectory with no further guidance, known as 'going dumb'." ], [ "Service history", "===U.S.", "combat experience===QF-4B target drone, 1983.", "* On January 5, 1999, a pair of US F-14s fired two Phoenixes at Iraqi MiG-25s southeast of Baghdad.", "Both AIM-54s' rocket motors failed and neither missile hit its target.", "* On September 9, 1999, another US F-14 launched an AIM-54 at an Iraqi MiG-23 that was heading south into the no-fly zone from Al Taqaddum air base west of Baghdad.", "The missile missed, eventually going into the ground after the Iraqi fighter reversed course and fled north.An AIM-54 Phoenix being attached

replaced by shorter-range AIM-120 AMRAAMs, employed on the F/A-18E/F Super Hornet.Despite the much-vaunted capabilities, the Phoenix was rarely used in combat, with only two confirmed launches and no confirmed targets destroyed in US Navy service.", "The USAF F-15 Eagle had responsibility for overland combat air patrol duties in Operation Desert Storm in 1991, primarily because of the onboard F-15 IFF capabilities.", "The Tomcat did not have the requisite IFF capability mandated by the JFACC to satisfy the rules of engagement to utilize the Phoenix capability at beyond visual range.", "The AIM-54 was not adopted by any foreign nation besides Iran, or any other US armed service, and was not used on any aircraft other than the F-14.===Iranian combat experience===Iranian F-14 Tomcats armed with multiple types of air-to-air missiles, including AIM-54 Phoenixes, in 1986.On January 7, 1974, as part of Project ''Persian King'', the Imperial Iranian Air Force placed an order for 424 AIM-54As, later increasing it by 290 missiles that June.", "Of the initial order, 274 missiles and 10 training rounds were delivered for US$150 million, until the 1979 Revolution ended deliveries and left the remaining 150 missiles embargoed and the additional order of 290 cancelled.According to Tom Cooper and Farzad Bishop, during the Iran–Iraq War AIM-54s fired by IRIAF Tomcats achieved 78 victories against Iraqi MiG-21s, MiG-23s, MiG-25s, Tu-22s, Su-20/22s, Mirage F 1s, Super Étendards, and even two AM-39 Exocets and a C-601.This includes two occasions where one AIM-54 was responsible for the downing of two Iraqi aircraft, as well as an incident on January 7, 1981, where a Phoenix fired at a four-ship of MiG-23s downed three and damaged the fourth.The US refused to supply spare parts and maintenance after the 1979 Revolution, except for a brief period during the Iran–Contra affair.", "According to Cooper, the Islamic Republic of Iran Air Force kept its F-14 fighters and AIM-54 missiles in regular use during the entire Iran–Iraq War, though periodic lack of spares grounded large parts of the fleet at times.", "During late 1987, the stock of AIM-54 missiles was at its lowest, with fewer than 50 operational missiles available.", "The missiles needed fresh thermal batteries that could only be purchased from the US.", "Iran found a clandestine buyer that supplied it with batteries, which cost up to US$10,000 each.", "Iran received spares and parts for both the F-14s and AIM-54s from various sources during the Iran–Iraq War, and has received more spares after the conflict.", "Iran started a program to build spares for the planes and missiles, and although there are claims that it no longer relies on outside sources to keep its F-14s and AIM-54s operational, there is evidence that Iran continues to procure parts clandestinely.Both the F-14 Tomcat and the AIM-54 Phoenix missile continue in the service of the Islamic Republic of Iran Air Force.", "Iran

[ [ "Lockheed AC-130" ], [ "Introduction", "The '''Lockheed AC-130''' gunship is a heavily armed, long-endurance, ground-attack variant of the C-130 Hercules transport, fixed-wing aircraft.", "It carries a wide array of ground-attack weapons that are integrated with sophisticated sensors, navigation, and fire-control systems.", "Unlike other modern military fixed-wing aircraft, the AC-130 relies on visual targeting.", "Since its large profile and low operating altitudes around 7,000 feet (2,100 m) make it an easy target, its close air support missions are usually flown at night.The airframe is manufactured by Lockheed Martin, while Boeing is responsible for the conversion into a gunship and for aircraft support.", "Developed during the Vietnam War as \"Project Gunship II\", the AC-130 replaced the Douglas AC-47 Spooky, or \"Gunship I\".", "The sole operator is the United States Air Force, which uses the '''AC-130U Spooky''' and '''AC-130W Stinger II''' variants for close air support, air interdiction, and force protection, with the upgraded '''AC-130J Ghostrider''' entering service.", "Close air support roles include supporting ground troops, escorting convoys, and urban operations.", "Air-interdiction missions are conducted against planned targets and targets of opportunity.", "Force-protection missions include defending air bases and other facilities.", "AC-130Us are based at Hurlburt Field, Florida, while AC-130Ws are based at Cannon AFB, New Mexico; gunships can be deployed worldwide.", "The squadrons are part of the Air Force Special Operations Command (AFSOC), a component of the United States Special Operations Command.The AC-130 has an unpressurized cabin, with the weaponry mounted to fire from the port side of the fuselage.", "During an attack, the gunship performs a pylon turn, flying in a large circle around the target, so is able to fire at it for far longer than in a conventional strafing attack.", "The AC-130H Spectre was armed with two M61 Vulcan cannons, one L/60 Bofors 40 mm cannon, and M137 cannon and M37 recoil mechanism from the M102 howitzer; after 1994, the cannons were removed.", "The upgraded AC-130U Spooky has a GAU-12 Equalizer cannon in place of the Spectre's two cannons, an improved fire-control system, and increased ammunition capacity.", "The new AC-130J was based on the MC-130J Commando II special-operations tanker.", "The AC-130W Stinger II is a modified C-130H with upgrades including a precision strike package." ], [ "Development", "===Origins===During the Vietnam War, the C-130 Hercules was selected to replace the Douglas AC-47 Spooky gunship (Project Gunship I) to improve mission endurance and increase capacity to carry munitions.", "Capable of flying faster than helicopters and at high altitudes with excellent loiter time, the use of the pylon turn allowed the AC-47 to deliver continuous, accurate fire to a single point on the ground.AC-130H Spectre near Hurlburt Field, Florida in 1988In 1967, JC-130A 54-1626 was selected for conversion into the prototype AC-130A gunship (Project Gunship II).", "The modifications were done at Wright-Patterson Air Force Base by the Aeronautical Systems Division.", "A direct-view night-vision telescope was installed in the forward door, an early forward-looking infrared device was placed in the forward part of the left wheel well, with miniguns and rotary cannons fixed facing down and aft along the left side.", "The analog fire-control computer prototype was handcrafted by RAF Wing Commander Tom Pinkerton at the USAF Avionics Laboratory at Wright-Patterson AFB.", "Flight testing of the prototype was performed primarily at Eglin Air Force Base, followed by further testing and modifications.", "By September 1967, the aircraft was certified ready for combat testing and was flown to Nha Trang Air Base, South Vietnam, for a 90-day test program.", "The AC-130 was later supplemented by the AC-119 Shadow (Project Gunship III), which later proved to be underpowered.Seven more warplanes were converted to the \"Plain Jane\" configuration like the AC-130 prototype in 1968, and one aircraft received the \"Surprise Package\" refit in 1969.The Surprise Package upgrade included the latest 20 mm rotary autocannons and 40 mm Bofors cannon, but no 7.62 mm close-support armament.", "The Surprise Package configuration served as a test bed for the avionic systems and armament for the AC-130E.", "In 1970, 10 more AC-130As were acquired under the \"Pave Pronto\" project.", "In the summer of 1971, Surprise Package AC-130s were converted to the Pave Pronto configuration and assumed the new nickname of \"Thor\".", "Conversion of C-130Es into AC-130Es for the \"PAVE Spectre\" project followed.", "Regardless of their project names, the aircraft were more commonly referred to by the squadron's call sign, Spectre.===Recent and planned upgrades===AC-130U armed with two 30 mm Bushmasters, 2007In 2007, AFSOC initiated a program to upgrade the armament of AC-130s.", "The test program planned for the 25 mm GAU-12/U and 40 mm Bofors cannon on the AC-130U gunships to be replaced with two 30 mm Mk 44 Bushmaster II cannons.", "In 2007, the Air Force modified four AC-130U gunships as test platforms for the Bushmasters.", "These were referred to as AC-130U Plus 4 or AC-130U+4.AFSOC, however, canceled its plans to install the new cannons on its fleet of AC-130Us.", "It has since removed the guns and reinstalled the original 40 mm and 25 mm cannons and returned the planes to combat duty.", "Brigadier General Bradley A. Heithold, AFSOC's director of plans, programs, requirements, and assessments, said on 11 August 2008 that the effort was canceled because of problems with the Bushmaster's accuracy in tests \"at the altitude we were employing it\".", "Also, schedule considerations drove the decision, he said.Plans were made for the possible replacement of the 105 mm M102 howitzer with a breech-loading variant of the 120 mm M120 mortar.", "The 120mm breech-loading mortar concept offers more flexibility with the use of munitions that are currently available with greater lethality, precision strike capabilities, reduction in collateral damage, and decreased casualties in danger close scenarios.", "Also, using the newer AGM-114 Hellfire missiles, the Advanced Precision Kill Weapon System (based on the Hydra 70 rockets), or the Viper Strike glide bombs can dramatically increase the standoff capability of the AC-130.The conceptual breechloading variant of the 120mm M120 mortar has several key advantages over the conventional M102 105mm howitzer.", "100 rounds of ammunition weighs for the M102 105mm howitzer compared to for the M120 120mm mortar.", "The recoil load is with the 105mm howitzer compared to with the M120 120mm mortar.", "The gun recoiling weight for the M102 105mm howitzer is compared to for the M120 120mm mortar.", "The muzzle pressure for the M102 105mm howitzer is compared to for the M120 120mm mortar.In 2010, the Air Force awarded L-3 Communications a $61 million (~$ in ) contract to add precision strike packages to eight MC-130W Combat Spear special-mission aircraft to give them a gunship-like attack capability; such-equipped MC-130Ws are known as Dragon Spears.", "AFSOC is arming these aircraft to relieve the high operational demands on AC-130 gunships until new AC-130Js enter service.", "The MC-130W Dragon Spear was renamed '''AC-130W Stinger II''' in 2011.The precision strike packages consist of a 30 mm gun and several precision guided munitions.", "Rails are mounted on the outboard pylon of the wing for four Hellfire missiles, SDBs, or SDB IIs under each.", "Ten common launch tubes (CLTs) are mounted on the rear ramp to fire Griffin A missiles; additional missiles are stored in the aircraft that can be reloaded in flight.", "CLTs are able to fire other small munitions able to fit inside the -diameter, -long tubes.The AC-130J Ghostrider came from a 2011 initiative that sought to acquire 16 new gunships based on newly built MC-130J Combat Shadow II special-operations tankers outfitted with a \"precision strike package\" to give them an attack capability, requesting $1.6 billion from fiscal years 2011 through 2015.This was to increase the size of the gunship fleet to 33 aircraft, a net increase of eight after the planned retirement of eight aging AC-130Hs.", "The first aircraft would be bought in fiscal 2012, followed by two in fiscal 2013, five in fiscal 2014, and the final eight in fiscal 2015.The decision to retain the C-130 came after funding for 16 C-27Js was removed from the fiscal 2010 budget.The AC-130J was to follow the path of the Dragon Spear program.", "On 9 January 2013, the Air Force began converting the first MC-130J Combat Shadow II into an AC-130J.", "The first AC-130J was delivered to AFSOC on 29 July 2015.The first AC-130J gunships achieved initial operational capability (IOC) on 30 September 2017.The AC-130J has two planned increments: the Block 10 configuration includes an internal 30 mm gun, small diameter bombs, and laser-guided missiles launched from the rear cargo door; and Block 20 configuration adds a 105 mm cannon, large aircraft infrared countermeasures, wing-mounted Hellfire missiles, and radio-frequency countermeasures.The Air Force decided to add a 105 mm cannon to the AC-130J in addition to the 30 mm cannon and smart bombs, the shells being more accurate and cheaper than dropping SDBs.", "AFSOC also pursued a directed-energy weapon on board the AC-130J by 2022, similar to the previous Advanced Tactical Laser program.", "It was to produce a beam of up to 120 kW, or potentially even 180–200 kW, weigh about , defensively destroy antiaircraft missiles, and offensively engage communications towers, boats, cars, and aircraft.", "A laser armament would have only been installed on a few aircraft rather than the entire AC-130J fleet; the laser would be mounted on the side in place of the 30 mm cannon.", "AFSOC eventually ruled out the idea, determining that placing a laser out the side of the airframe would yield so much air turbulence that it would disrupt the beam.", "Other potential additions include an active denial system to perform airborne crowd control, and small unmanned aerial vehicles from the CLTs to provide remote video feed and coordinates to weapons operators through cloud cover.", "Called the Tactical Off-board Sensor (TOBS), the drones would be expendable and fly along a programmed orbit to verify targets the aircraft cannot see itself because of bad weather or standing off from air defenses.", "AFSOC was to initially use the Raytheon Coyote small UAV for the TOBS mission, as it is an off-the-shelf design with a one-hour endurance, but planned to fulfill the role with a new drone capable of a four-hour endurance by 2019.The Air Force was also interested in acquiring a glide bomb that can be launched from the CLTs, capable of hitting ground vehicles traveling as fast as 120 km/h (70 mph) while above .", "In June 2016, Dynetics was awarded a contract by SOCOM to integrate its tactical munition onto the AC-130.Designated the GBU-69/B Small Glide Munition, the weapon weighs and is armed with a blast-fragmentation warhead that can detonate by direct impact or at a selected height; despite being smaller, being unpowered allows for its warhead to be heavier than those on the Hellfire and Griffin A missiles, and , respectively.", "Guidance is provided by a GPS receiver with antispoofing software and four distributed-aperture semiactive laser seeker apertures adapted from the WGU-59/B APKWS for terminal guidance.", "Approval for fielding occurred in early 2017.Dynetics was awarded a contract to deliver an initial batch of 70 SGMs in June 2017, with plans to buy up to 1,000.The SGM can travel .===Future===, AC-130 gunships have been providing close air support for special operators for 56 years.", "Although the aircraft have been kept relevant through constant upgrades to their weaponry, sensor packages, and countermeasures, they are not expected to be survivable in future nonpermissive environments due to their high signatures and low airspeeds.", "Military analysts, such as the Center for Strategic and Budgetary Assessments, have suggested that AFSOC invest in more advanced technologies to fill the role to operate in future contested combat zones, including a mix of low-cost disposable unmanned and stealthy strike aircraft.", "AFSOC is considering a number of changes to the AC-130J in order to make it effective against advanced adversaries including removing the 105 mm cannon and upgrading the aircraft with small cruise missiles, an AESA radar, and networking enhancements." ], [ "Design", "Underside of an AC-130U Spooky===Overview===The AC-130 is a heavily armed, long-endurance aircraft carrying an array of weapons against ground targets that are integrated with sophisticated sensors, navigation, and fire-control systems.", "It is capable of delivering precision firepower or area-saturation fire over a target area over a long period of time, at night, or in adverse weather.", "The sensor suite consists of an electro-optical image sensor, infrared sensor, and radar.", "These sensors allow the gunship to visually or electronically identify friendly ground forces and targets in most weather conditions.The AC-130U is equipped with the AN/APQ-180, a synthetic aperture radar, for long-range target detection and identification.", "The gunship's navigational devices include inertial navigation systems and a global positioning system.", "The AC-130U employs technologies developed in the 1990s, which allow it to attack two targets simultaneously.", "It has twice the munitions capacity of the AC-130H.", "Although the AC-130U conducts some operations in daylight, most of its combat missions are conducted at night.", "The AC-130H's unit cost is US$132.4 million, and the AC-130U's cost is $190 million (fiscal 2001 dollars).===Upgrades===AC-130U sensor suiteDuring the Vietnam War era, the various AC-130 versions following the Pave Pronto modifications were equipped with a magnetic anomaly detector system called Black Crow (designated AN/ASD-5), a highly sensitive passive device with a phased-array antenna located in the left-front nose radome that could pick up localized deviations in the Earth's magnetic field normally used to detect submerged submarines.", "The Black Crow system was slaved into the targeting computers of the AC-130A/E/H, enabling the detection of the unshielded ignition coils of North Vietnamese trucks hidden under dense jungle foliage along the Ho Chi Minh Trail.", "It could also detect hand-held transmitter signals of air controllers on the ground to identify and locate targets.The PGM-38/U enhanced 25 mm high-explosive incendiary round was created to expand the AC-130U gunships' mission in standoff range and survivability for its 25 mm GAU-12/U gun.", "This round is a combination of the existing PGU-25 HEI and a M758 fuze designated as FMU-151/B to meet the MIL-STD-1316.The FMU-151 has an improved arming delay with multisensitive range." ], [ "Operational history", "===Vietnam War===An AC-130 in Southern Laos ''circa'' 1970The AC-130 gunship first arrived in South Vietnam on 21 September 1967 under the Gunship II program and began combat operations over Laos and South Vietnam that same year.", "In June 1968, AC-130s were deployed to Tan Son Nhut AB near Saigon for support against the Tet Offensive.", "By 30 October 1968, enough AC-130 Gunship IIs arrived to form a squadron, the 16th Special Operations Squadron of the 8th Tactical Fighter Wing, at Ubon Royal Thai Air Force Base, Thailand.", "At this time, the C-130A gunship was designated the AC-130A.On 18 August 1968, an AC-130 gunship flying an armed reconnaissance mission in Vietnam's III Corps was diverted to support the Katum Special Forces Camp.", "The ground commander quickly assessed the accurate fire and capabilities of this weapons system and called for fire on his own perimeter when the Viet Cong attempted to bridge the wire on the west side of his position.By December 1968, most AC-130s flew under F-4 Phantom II escort (to protect the gunship against heavy and concentrated antiaircraft fire) from the 497th Tactical Fighter Squadron, normally three Phantoms per gunship.", "On 24 May 1969, the first Spectre gunship was lost to enemy fire.In late 1969, under code name \"Surprise Package\", 56-0490 arrived with solid-state, laser-illuminated, low light-level TV with a companion YAG laser designator, an improved forward-looking infrared (FLIR) sensor, video recording for TV and FLIR, an inertial navigation system, and a prototype digital fire-control computer.", "The remaining AC-130s were refitted with upgraded similar equipment in the summer of 1970, and then redeployed to Ubon RTAFB.", "On 25 October 1971, the first \"Cadillac\" gunship, the AC-130E, arrived in Vietnam.", "On 17 February 1972, the first 105 mm cannon arrived for service with Spectre and was installed on Gunship 570.It was used from mid-February until the aircraft received battle damage to its right flap.", "The cannon was switched to Gunship 571 and was used until 30

offensive operations in Laos ended and the gunships became totally committed to operations in the Cambodian conflict.On 12 April 1975, the Khmer Rouge was threatening the capital of Phnom Penh and AC-130s were called on to help in Operation Eagle Pull, the final evacuation of American and allied officials from Phnom Penh before it was conquered by the communists.", "The AC-130 was also over Saigon on 30 April 1975 to protect the final evacuation in Operation Frequent Wind.", "Spectres were also called in when the USS ''Mayaguez'' was seized, on the open sea, by Khmer Rouge soldiers and sailors on 15 May 1975.Six AC-130s and 52 air crew members were lost during the war.", "AC-130s reportedly destroyed more than 10,000 trucks and participated in many crucial close-air-support missions in Vietnam.===Cold War and later action===An AC-130A performs a left-hand pylon turn.With the conclusion of hostilities in Southeast Asia in the mid-1970s, the AC-130H became the sole gunship in the regular Air Force, home based at Hurlburt Field, Florida, while the AC-130A fleet was transferred to the Air Force Reserve's 919th Tactical Airlift Group (919 TAG) at Eglin AFB Auxiliary Field #3/Duke Field, Florida.", "With the transition to the AC-130A, the 919 TAG was then redesignated as the 919th Special Operations Group.In the late 1970s, when the AC-130H fleet was first being modified for in-flight refueling capability, a demonstration mission was planned and flown from Hurlburt Field, Florida, nonstop, to conduct a 2-hour live-fire mission over Empire Firing Range in the Republic of Panama, then return home.", "This 13-hour mission with two in-flight refuelings from KC-135 tankers proved the validity of flying long-range missions outside the contiguous United States to attack targets then return to home base without intermediate stops.AC-130s from both the 4th and 16th Special Operations Squadrons have been deployed in nearly every conflict in which the United States has been involved, officially and unofficially, since the end of the Vietnam War.In July 1979, AC-130H crews deployed to Howard Air Force Base, Panama, as a precaution against possible hostile actions against American personnel during the Nicaraguan Revolution.", "New time aloft and nonstop distance records were subsequently set by a 16th SOS two-ship AC-130H formation flight that departed Hurlburt Field on 13 November 1979 and landed on 15 November at Andersen Air Force Base, Guam, a distance of and 29 hours 43 minutes nonstop, refueling four times in-flight.", "Refueling support for the Guam deployment was provided by KC-135 crews from the 305th Air Refueling Wing from Grissom AFB, Indiana.In November 1979, four AC-130H gunships flew nonstop from Hurlburt Field to Anderson AFB, Guam, because of the hostage situation at the US Embassy in Iran.", "On Guam, AC-130H crews developed communications-out/lights-out refueling procedures for later employment by trial-and-error.", "This deployment with the 1 SOW/CC as task force commander was directed from the office of the CJCS for fear that Iranian militants could begin executing American Embassy personnel who had been taken hostage on 4 November.", "One early option considered AC-130H retaliatory punitive strikes deep within Iran.", "Later gunship flights exceeded the 1979 Hurlburt-to-Guam flight.", "Upon return in March 1980, the four planes soon found themselves in Egypt to support the ill-fated hostage rescue attempt.Smoke visible from rotary cannon during twilight operations in 1988During Operation Urgent Fury in Grenada in 1983, AC-130s suppressed enemy air-defense systems and attacked ground forces enabling the assault of the Point Salines Airfield via airdrop and air-land of friendly forces.", "The AC-130 aircrew earned the Lieutenant General William H. Tunner Award for the mission.The AC-130Hs of the 16th Special Operations Squadron unit maintained an ongoing rotation to Howard AB, Panama, monitoring activities in El Salvador and other Central American points of interest, with rules of engagement eventually permitting attacks on FMLN targets.", "This commitment of maintainers and crews started in 1983 and lasted until 1990.The AC-130 is considered to have hastened the end of the Salvadoran Civil War in the 1980s.", "Crews flew undercover missions from Honduras and attacked guerrilla camps and concentrations.AC-130s also had a primary role during the United States invasion of Panama (named Operation Just Cause) in 1989, when they destroyed Panama Defense Force headquarters and numerous command-and-control facilities, and provided close air support for US ground troops.", "Aircrews earned the Mackay Trophy for the most meritorious flight of the year, and the Tunner Award.===Gulf War and the 1990s===A USAF AC-130 in combat operationDuring the Gulf War of 1990–1991 (Operations Desert Shield and Desert Storm), Regular Air Force and Air Force Reserve AC-130s provided close air support and force protection (air base defense) for ground forces, and battlefield interdiction.", "The primary interdiction targets were early-warning/ground-control intercept sites along the southern border of Iraq.", "At its standard altitude of , the aircraft had a proven ability to engage moving ground targets.", "The first gunship to enter the Battle of Khafji helped stop a southbound Iraqi armored column on 29 January 1991.One day later, three more gunships provided further aid to Marines participating in the operation.", "The gunships attacked Iraqi positions and columns moving south to reinforce their positions north of the city.Despite the threat of SAMs and increasing visibility during the early morning hours of 31 January 1991, one AC-130H, AF Serial No.", "69-6567, call-sign Spirit 03, opted to stay to continue to protect the Marines.", "A lone Iraqi with a Strela-2 MANPADS shot Spirit 03 down, and all 14 crew members were killed.", "The loss of Spirit 03 did however result in the US DoD joining the development of the AN/AAQ-24 Directed Infrared Countermeasures System which, in its updated laser-based form, is now a common fit across large US military aircraft.The military has used AC-130 gunships during the humanitarian operations in Somalia (Operation Restore Hope and Operation United Shield) in 1992–93 and Operation Uphold Democracy in Haiti in 1994.AC-130s took part in Operation Assured Response in Liberia in 1996 and in Operation Silver Wake in 1997, the evacuation of American non-combatants from Albania.AC-130s took part in the NATO missions in Bosnia and Herzegovina and Kosovo during the 1990s.The AC-130U gunship set a new record for the longest sustained flight by any C-130 on 22 and 23 October 1997, when two AC-130U gunships flew 36 hours nonstop from Hurlburt Field to Taegu Air Base (Daegu), South Korea, being refueled seven times in the air by KC-135 tankers.", "The two gunships took on 410,000 lb (186,000 kg) of fuel.", "Gunships also were part of the buildup of US forces in 1998 to compel Iraq to allow UNSCOM weapons inspections.===War on Terror===flaresThe US has used gunships with deployments to the War in Afghanistan (Operation Enduring

the war in Afghanistan.", "US Special Operations Forces used the AC-130 to support its operations.", "The day after arriving in Afghanistan, the AC-130s attacked Taliban and Al-Qaeda forces near the city of Kunduz and were directly responsible for the city's surrender the next day.", "On 26 November 2001, Spectres were called in to put down a rebellion at the prison fort of Qala-I-Jangi.", "The 16 SOS flew missions over Mazar-i-Sharif, Kunduz, Kandahar, Shkin, Asadabad, Bagram, Baghran, Tora Bora, and virtually every other part of Afghanistan.", "The Spectre participated in countless operations within Afghanistan, performing on-call close air support and armed reconnaissance.", "In March 2002, three AC-130 Spectres provided 39 crucial combat missions in support of Operation Anaconda in Afghanistan.", "During the intense fighting, the planes fired more than 1,300 40  mm and 1,200 105  mm rounds.Close air support was the main mission of the AC-130 in Iraq.", "Night after night, at least one AC-130 was in the air to fulfill one or more air-support requests (ASRs).", "A typical mission had the AC–130 supporting a single brigade's ASRs followed by aerial refueling and another two hours with another brigade or SOF team.", "The use of AC-130s in places like Fallujah, urban settings where insurgents were among crowded populations of non-combatants, was criticized by human rights groups.", "AC-130s were also used for intelligence gathering with their sophisticated long-range video, infrared and radar sensors.", "In 2007, US Special Operations forces also used the AC-130 in attacks on suspected Al-Qaeda militants in Somalia.Eight AC-130H and 17 AC-130U aircraft were in active-duty service as of July 2010.In March 2011, the Air Force deployed two AC-130U gunships to take part in Operation Odyssey Dawn, the US military intervention in Libya, which eventually came under NATO as Operation Unified Protector.By September 2013, 14 MC-130W Dragon Spear aircraft have been converted to AC-130W Stinger II gunships.", "The Stinger gunships have been deployed to Afghanistan to replace the aging AC-130H aircraft and provide an example for the new AC-130J Ghostrider.", "Modifications began by cutting holes in the plane to make room for weapons and adding kits and bomb bases for laser-guided munitions.", "Crews added a 105 mm cannon, 20-inch infrared and electro-optical sensors, and the ability to carry 250-lb bombs on the wings.The final AC-130H Spectre gunship, tail number 69-6569 \"Excalibur\" was retired on 26 May 2015 at Cannon Air Force Base, New Mexico.On 15 November 2015, two days after the attacks in Paris by ISIL, AC-130s and A-10 Thunderbolt II attack aircraft destroyed a convoy of over 100 ISIL-operated oil tanker trucks in Syria.", "The attacks were part of an intensification of the US-led military intervention against ISIL called Operation Tidal Wave II (named after the original Operation Tidal Wave during World War II, a failed attempt to raid German oil fields that resulted in heavy aircraft and aircrew loss) in an attempt to cut off oil smuggling as a source of funding for the group.On 3 October 2015, an AC-130 mistakenly attacked the Doctors Without Borders hospital in Kunduz, Afghanistan, killing 42 people and injuring over 30.In five separate runs, the gunship struck the hospital, that was erroneously identified as the source of attacks on coalition members.", "Subsequent inquiries led to punishment of 16 military personnel and cited \"human error\" as the root cause.On 30 September 2017, the Air Force declared the AC-130J Ghostrider had achieved initial operational capability, with six gunships having been delivered; the aircraft is planned to reach full operational capability

[ [ "Arbitrage" ], [ "Introduction", "In economics and finance, '''arbitrage''' (, ) is the practice of taking advantage of a difference in prices in two or more marketsstriking a combination of matching deals to capitalise on the difference, the profit being the difference between the market prices at which the unit is traded.", "When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state; in simple terms, it is the possibility of a risk-free profit after transaction costs.", "For example, an arbitrage opportunity is present when there is the possibility to instantaneously buy something for a low price and sell it for a higher price.In principle and in academic use, an arbitrage is risk-free; in common use, as in statistical arbitrage, it may refer to ''expected'' profit, though losses may occur, and in practice, there are always risks in arbitrage, some minor (such as fluctuation of prices decreasing profit margins), some major (such as devaluation of a currency or derivative).", "In academic use, an arbitrage involves taking advantage of differences in price of a ''single'' asset or ''identical'' cash-flows; in common use, it is also used to refer to differences between ''similar'' assets (relative value or convergence trades), as in merger arbitrage.The term is mainly applied to trading in financial instruments, such as bonds, stocks, derivatives, commodities, and currencies.", "People who engage in arbitrage are called '''arbitrageurs''' ().", "Arbitrage has the effect of causing prices of the same or very similar assets in different markets to converge." ], [ "Etymology", "\"Arbitrage\" is a French word and denotes a decision by an arbitrator or arbitration tribunal (in modern French, \"\" usually means referee or umpire).", "In the sense used here, it was first defined in 1704 by Mathieu de la Porte in his treatise \"\" as a consideration of different exchange rates to recognise the most profitable places of issuance and settlement for a bill of exchange (\" , in modern spelling \".)" ], [ "Arbitrage-free", "If the market prices do not allow for profitable arbitrage, the prices are said to constitute an '''arbitrage equilibrium''', or an '''arbitrage-free''' market.", "An arbitrage equilibrium is a precondition for a general economic equilibrium.", "The \"no arbitrage\" assumption is used in quantitative finance to calculate a unique risk neutral price for derivatives." ], [ "Arbitrage-free pricing approach for bonds", "Arbitrage-free pricing for bonds is the method of valuing a coupon-bearing financial instrument by discounting its future cash flows by multiple discount rates.", "By doing so, a more accurate price can be obtained than if the price is calculated with a present-value pricing approach.", "Arbitrage-free pricing is used for bond valuation and to detect arbitrage opportunities for investors.For the purpose of valuing the price of a bond, its cash flows can each be thought of as packets of incremental cash flows with a large packet upon maturity, being the principal.", "Since the cash flows are dispersed throughout future periods, they must be discounted back to the present.", "In the present-value approach, the cash flows are discounted with one discount rate to find the price of the bond.", "In arbitrage-free pricing, multiple discount rates are used.The present-value approach assumes that the bond yield will stay the same until maturity.", "This is a simplified model because interest rates may fluctuate in the future, which in turn affects the yield on the bond.", "For this reason, the discount rate may differ for each cash flow.", "Each cash flow can be considered a zero-coupon instrument that pays one payment upon maturity.", "The discount rates used should be the rates of multiple zero-coupon bonds with maturity dates the same as each cash flow and similar risk as the instrument being valued.", "By using multiple discount rates, the arbitrage-free price is the sum of the discounted cash flows.", "Arbitrage-free price refers to the price at which no price arbitrage is possible.The idea of using multiple discount rates obtained from zero-coupon bonds and discounting a similar bond's cash flow to find its price is derived from the yield curve, which is a curve of the yields of the same bond with different maturities.", "This curve can be used to view trends in market expectations of how interest rates will move in the future.", "In arbitrage-free pricing of a bond, a yield curve of similar zero-coupon bonds with different maturities is created.", "If the curve were to be created with Treasury securities of different maturities, they would be stripped of their coupon payments through bootstrapping.", "This is to transform the bonds into zero-coupon bonds.", "The yield of these zero-coupon bonds would then be plotted on a diagram with time on the ''x''-axis and yield on the ''y''-axis.Since the yield curve displays market expectations on how yields and interest rates may move, the arbitrage-free pricing approach is more realistic than using only one discount rate.", "Investors can use this approach to value bonds and find price mismatches, resulting in an arbitrage opportunity.", "If a bond valued with the arbitrage-free pricing approach turns out to be priced higher in the market, an investor could have such an opportunity:#Investor shorts the bond at price at time t1.#Investor longs the zero-coupon bonds making up the related yield curve and strips and sells any coupon payments at t1.#As t>t1, the price spread between the prices will decrease.#At maturity, the prices will converge and be equal.", "Investor exits both the long and short positions, realising a profit.If the outcome from the valuation were the reverse case, the opposite positions would be taken in the bonds.", "This arbitrage opportunity comes from the assumption that the prices of bonds with the same properties will converge upon maturity.", "This can be explained through market efficiency, which states that arbitrage opportunities will eventually be discovered and corrected.", "The prices of the bonds in t1 move closer together to finally become the same at tT." ], [ "Conditions for arbitrage", "Arbitrage may take place when:* the same asset does not trade at the same price on all markets (\"the law of one price\").", "* two assets with identical cash flows do not trade at the same price.", "* an asset with a known price in the future does not today trade at its future price discounted at the risk-free interest rate (or the asset has significant costs of storage; so this condition holds true for something like grain but not for securities).Arbitrage is not simply the act of buying a product in one market and selling it in another for a higher price at some later time.", "The transactions must occur ''simultaneously'' to avoid exposure to market risk, or the risk that prices may change in one market before both transactions are complete.", "In practical terms, this is generally possible only with securities and financial products that can be traded electronically, and even then, when each leg of the trade is executed, the prices in the market may have moved.", "Missing one of the legs of the trade (and subsequently having to trade it soon after at a worse price) is called 'execution risk' or more specifically 'leg risk'.In the simplest example, any good sold in one market should sell for the same price in another.", "Traders may, for example, find that the price of wheat is lower in agricultural regions than in cities, purchase the good, and transport it to another region to sell at a higher price.", "This type of price arbitrage is the most common, but this simple example ignores the cost of transport, storage, risk, and other factors.", "\"True\" arbitrage requires that there is no market risk involved.", "Where securities are traded on more than one exchange, arbitrage occurs by simultaneously buying in one and selling on the other.See rational pricing, particularly § arbitrage mechanics, for further discussion.Mathematically it is defined as follows:: where , denotes the portfolio value at time ''t'' and ''T'' is the time the portfolio ceases to be available on the market.", "This means that the value of the portfolio is never negative, and guaranteed to be positive at least once over its lifetime.Negative, or anti-, arbitrage is similarly defined as: and occurs naturally in arbitrage relations as the seller view as opposed to the buyer view." ], [ "Price convergence", "Arbitrage has the effect of causing prices in different markets to converge.", "As a result of arbitrage, the currency exchange rates, the price of commodities, and the price of securities in different markets tend to converge.", "The speed at which they do so is a measure of market efficiency.", "Arbitrage tends to reduce price discrimination by encouraging people to buy an item where the price is low and resell it where the price is high (as long as the buyers are not prohibited from reselling and the transaction costs of buying, holding, and reselling are small, relative to the difference in prices in the different markets).Arbitrage moves different currencies toward purchasing power parity.", "Assume that a car purchased in the United States is cheaper than the same car in Canada.", "Canadians would buy their cars across the border to exploit the arbitrage condition.", "At the same time, Americans would buy US cars, transport them across the border, then sell them in Canada.", "Canadians would have to buy American dollars to buy the cars and Americans would have to sell the Canadian dollars they received in exchange.", "Both actions would increase demand for US dollars and supply of Canadian dollars.", "As a result, there would be an appreciation of the US currency.", "This would make US cars more expensive and Canadian cars less so until their prices were similar.", "On a larger scale, international arbitrage opportunities in commodities, goods, securities, and currencies tend to change exchange rates until the purchasing power is equal.In reality, most assets exhibit some difference between countries.", "These, transaction costs, taxes, and other costs provide an impediment to this kind of arbitrage.", "Similarly, arbitrage affects the difference in interest rates paid on government bonds issued by the various countries, given the expected depreciation in the currencies relative to each other (see interest rate parity)." ], [ "Risks", "Arbitrage transactions in modern securities markets involve fairly low day-to-day risks, but can face extremely high risk in rare situations, particularly financial crises, and can lead to bankruptcy.", "Formally, arbitrage transactions have negative skew – prices can get a small amount closer (but often no closer than 0), while they can get very far apart.", "The day-to-day risks are generally small because the transactions involve small differences in price, so an execution failure will generally cause a small loss (unless the trade is very big or the price moves rapidly).", "The rare case risks are extremely high because these small price differences are converted to large profits via leverage (borrowed money), and in the rare event of a large price move, this may yield a large loss.The principal risk, which is typically encountered on a routine basis, is classified as execution risk.", "This transpires when an aspect of the financial transaction does not materialize as anticipated.", "Infrequent, albeit critical, risks encompass counterparty and liquidity risks.", "The former, counterparty risk, is characterized by the failure of the other participant in a substantial transaction, or a series of transactions, to fulfill their financial obligations.", "Liquidity risk, conversely, emerges when an entity is necessitated to allocate additional monetary resources as margin, but encounters a deficit in the required capital.In the academic literature, the idea that seemingly very low-risk arbitrage trades might not be fully exploited because of these risk factors and other considerations is often referred to as limits to arbitrage.===Execution risk===Generally, it is impossible to close two or three transactions at the same instant; therefore, there is the possibility that when one part of the deal is closed, a quick shift in prices makes it impossible to close the other at a profitable price.", "However, this is not necessarily the case.", "Many exchanges and inter-dealer brokers allow multi legged trades (e.g.", "basis block trades on LIFFE).Competition in the marketplace can also create risks during arbitrage transactions.", "As an example, if one was trying to profit from a price discrepancy between IBM on the NYSE and IBM on the London Stock Exchange, they may purchase a large number of shares on the NYSE and find that they cannot simultaneously sell on the LSE.", "This leaves the arbitrageur in an unhedged risk position.In the 1980s, risk arbitrage was common.", "In this form of speculation, one trades a security that is clearly undervalued or overvalued, when it is seen that the wrong valuation is about to be corrected.", "The standard example is the stock of a company, undervalued in the stock market, which is about to be the object of a takeover bid; the price of the takeover will more truly reflect the value of the company, giving a large profit to those who bought at the current price, if the merger goes through as predicted.", "Traditionally, arbitrage transactions in the securities markets involve high speed, high volume, and low risk.", "At some moment a price difference exists, and the problem is to execute two or three balancing transactions while the difference persists (that is, before the other arbitrageurs act).", "When the transaction involves a delay of weeks or months, as above, it may entail considerable risk if borrowed money is used to magnify the reward through leverage.", "One way of reducing this risk is through the illegal use of inside information, and risk arbitrage in leveraged buyouts was associated with some of the famous financial scandals of the 1980s, such as those involving Michael Milken and Ivan Boesky.===Mismatch===Another risk occurs if the items being bought and sold are not identical and the arbitrage is conducted under the assumption that the prices of the items are correlated or predictable; this is more narrowly referred to as a convergence trade.", "In the extreme case this is merger arbitrage, described below.", "In comparison to the classical quick arbitrage transaction, such an operation can produce disastrous losses.===Counterparty risk===As arbitrages generally involve ''future'' movements of cash, they are subject to counterparty risk: the risk that a counterparty fails to fulfill their side of a transaction.", "This is a serious problem if one has either a single trade or many related trades with a single counterparty, whose failure thus poses a threat, or in the event of a financial crisis when many counterparties fail.", "This hazard is serious because of the large quantities one must trade in order to make a profit on small price differences.For example, if one purchases many risky bonds, then hedges them with CDSes, profiting from the difference between the bond spread and the CDS premium, in a financial crisis, the bonds may default ''and'' the CDS writer/seller may fail, due to the stress of the crisis, causing the arbitrageur to face steep losses.===Liquidity risk===Arbitrage trades are necessarily synthetic, ''leveraged'' trades, as they involve a short position.", "If the assets used are not identical (so a price divergence makes the trade temporarily lose money), or the margin treatment is not identical, and the trader is accordingly required to post margin (faces a margin call), the trader may run out of capital (if they run out of cash and cannot borrow more) and be forced to sell these assets at a loss even though the trades may be expected to ultimately make money.", "In effect, arbitrage traders synthesise a put option on their ability to finance themselves.Prices may diverge during a financial crisis, often termed a \"flight to quality\"; these are precisely the times when it is hardest for leveraged investors to raise capital (due to overall capital constraints), and thus they will lack capital precisely when they need it most.=== Gray market ===Grey market arbitrage is the sale of goods purchased through informal channels to earn the difference in price.", "Excessive gray market arbitrage will lead to arbitrage behaviors in formal channels, which will reduce returns due to factors such as price confusion, and may even cause prices to plummet in severe cases." ], [ "Types", "===Spatial arbitrage===Also known as '''geographical arbitrage''', this is the simplest form of arbitrage.", "In spatial arbitrage, an arbitrageur looks for price differences between geographically separate markets.", "For example, there may be a bond dealer in Virginia offering a bond at 100-12/23 and a dealer in Washington bidding 100-15/23 for the same bond.", "For whatever reason, the two dealers have not spotted the difference in the prices, but the arbitrageur does.", "The arbitrageur immediately buys the bond from the Virginia dealer and sells it to the Washington dealer.===Latency arbitrage===For very short amounts of time, the prices of two assets that are either fungible or related by a strict pricing relationship may temporarily go out of sync as the market makers are slow to update the prices.", "This momentary mispricing creates the opportunity for an arbitrageur to capture the difference between the two prices.", "For example, the price of calls and puts on an underlying should be related by put-call parity.", "If these prices are misquoted relative to the put-call parity relationship, it provides an arbitrageur the opportunity to profit from the mispricing.Latency arbitrage is often mentioned especially in an electronic trading environment, where the use of fast server hardware allows an arbitrageur to capture realize opportunities that may exist for as little as nanoseconds.", "A study by the Financial Conduct Authority of the United Kingdom found that this practice generates as much as $5 billion per year in profit.===Merger arbitrage===Also called risk arbitrage, merger arbitrage generally consists of buying/holding the stock of a company that is the target of a takeover while shorting the stock of the acquiring company.Usually, the market price of the target company is less than the price offered by the acquiring company.The spread between these two prices depends mainly on the probability and the timing of the takeover being completed as well as the prevailing level of interest rates.The bet in a merger arbitrage is that such a spread will eventually be zero, if and when the takeover is completed.", "The risk is that the deal \"breaks\" and the spread massively widens.===Municipal bond arbitrage===Also called ''municipal bond relative value arbitrage'', ''municipal arbitrage'', or just ''muni arb'', this hedge fund strategy involves one of two approaches.", "The term \"arbitrage\" is also used in the context of the Income Tax Regulations governing the investment of proceeds of municipal bonds; these regulations, aimed at the issuers or beneficiaries of tax-exempt municipal bonds, are different and, instead, attempt to remove the issuer's ability to arbitrage between the low tax-exempt rate and a taxable investment rate.Generally, managers seek relative value opportunities by being both long and short municipal bonds with a duration-neutral book.", "The relative value trades may be between different issuers, different bonds issued by the same entity, or capital structure trades referencing the same asset (in the case of revenue bonds).", "Managers aim to capture the inefficiencies arising from the heavy participation of non-economic investors (i.e., high income \"buy and hold\" investors seeking tax-exempt income) as well as the \"crossover buying\" arising from corporations' or individuals' changing income tax situations (i.e., insurers switching their munis for corporates after a large loss as they can capture a higher after-tax yield by offsetting the taxable corporate income with underwriting losses).", "There are additional inefficiencies arising from the highly fragmented nature of the municipal bond market which has two million outstanding issues and 50,000 issuers, in contrast to the Treasury market which has 400 issues and a single issuer.Second, managers construct leveraged portfolios of AAA- or AA-rated tax-exempt municipal bonds with the duration risk hedged by shorting the appropriate ratio of taxable corporate bonds.", "These corporate equivalents are typically interest rate swaps referencing Libor or SIFMA.", "The arbitrage manifests itself in the form of a relatively cheap longer maturity municipal bond, which is a municipal bond that yields significantly more than 65% of a corresponding taxable corporate bond.", "The steeper slope of the municipal yield curve allows participants to collect more after-tax income from the municipal bond portfolio than is spent on the interest rate swap; the carry is greater than the hedge expense.", "Positive, tax-free carry from muni arb can reach into the double digits.", "The bet in this municipal bond arbitrage is that, over a longer period of time, two similar instruments—municipal bonds and interest rate swaps—will correlate with each other; they are both very high quality credits, have the same maturity and are denominated in the same currency.", "Credit risk and duration risk are largely eliminated in this strategy.", "However, basis risk arises from use of an imperfect hedge, which results in significant, but range-bound principal volatility.", "The end goal is to limit this principal volatility, eliminating its relevance over time as the high, consistent, tax-free cash flow accumulates.", "Since the inefficiency is related to government tax policy, and hence is structural in nature, it has not been arbitraged away.However, many municipal bonds are callable, and this adds substantial risks to the strategy.===Convertible bond arbitrage===A convertible bond is a bond that an investor can return to the issuing company in exchange for a predetermined number of shares in the company.A convertible bond can be thought of as a corporate bond with a stock call option attached to it.The price of a convertible bond is sensitive to three major factors:*''interest rate''.", "When rates move higher, the bond part of a convertible bond tends to move lower, but the call option part of a convertible bond moves higher (and the aggregate tends to move lower).", "*''stock price''.", "When the price of the stock the bond is convertible into moves higher, the price of the bond tends to rise.", "*''credit spread''.", "If the creditworthiness of the issuer deteriorates (e.g.", "rating downgrade) and its credit spread widens, the bond price tends to move lower, but, in many cases, the call option part of the convertible bond moves higher (since credit spread correlates with volatility).Given the complexity of the calculations involved and the convoluted structure that a convertible bond can have, an arbitrageur often relies on sophisticated quantitative models in order to identify bonds that are trading cheap versus their theoretical value.Convertible arbitrage consists of buying a convertible bond and hedging two of the three factors in order to gain exposure to the third factor at a very attractive price.For instance an arbitrageur would first buy a convertible bond, then sell fixed income securities or interest rate futures (to hedge the interest rate exposure) and buy some credit protection (to hedge the risk of credit deterioration).Eventually what he or she would be left with is something similar to a call option on the underlying stock, acquired at a very low price.He or she could then make money either selling some of the more expensive options that are openly traded in the market or delta hedging his or her exposure to the underlying shares.===Depository receipts===A depositary receipt is a security that is offered as a \"tracking stock\" on another foreign market.", "For instance, a Chinese company wishing to raise more money may issue a depository receipt on the New York Stock Exchange, as the amount of capital on the local exchanges is limited.", "These securities, known as ADRs (American depositary receipt) or GDRs (global depository receipt) depending on where they are issued, are typically considered \"foreign\" and therefore trade at a lower value when first released.", "Many ADR's are exchangeable into the original security (known as fungibility) and actually have the same value.", "In this case, there is a spread between the perceived value and real value, which can be extracted.", "Other ADR's that are not exchangeable often have much larger spreads.", "Since the ADR is trading at a value lower than what it is worth, one can purchase the ADR and expect to make money as its value converges on the original.", "However, there is a chance that the original stock will fall in value too, so by shorting it one can hedge that risk.===Cross-border arbitrage===Cross-border arbitrage exploits different prices of the same stock in different countries:Example: Apple is trading on NASDAQ at US$108.84.The stock is also traded on the German electronic exchange, XETRA.", "If 1 euro costs US$1.11, a cross-border trader could enter a buy order on the XETRA at €98.03 per Apple share and a sell order at €98.07 per share.Some brokers in Germany do not offer access to the U.S. exchanges.", "Hence if a German retail investor wants to buy Apple stock, he needs to buy it on the XETRA.", "The cross-border trader would sell the Apple shares on XETRA to the investor and buy the shares in the same second on NASDAQ.", "Afterwards, the cross-border trader would need to transfer the shares bought on NASDAQ to the German XETRA exchange, where he is obliged to deliver the stock.In most cases, the quotation on the local exchanges is done electronically by high-frequency traders, taking into consideration the home price of the stock and the exchange rate.", "This kind of high-frequency trading benefits the public, as it reduces the cost to the German investor and enables them to buy U.S. shares.===Dual-listed companies===A dual-listed company (DLC) structure involves two companies incorporated in different countries contractually agreeing to operate their businesses as if they were a single enterprise, while retaining their separate legal identity and existing stock exchange listings.", "In integrated and efficient financial markets, stock prices of the twin pair should move in lockstep.", "In practice, DLC share prices exhibit large deviations from theoretical parity.", "Arbitrage positions in DLCs can be set up by obtaining a long position in the relatively underpriced part of the DLC and a short position in the relatively overpriced part.", "Such arbitrage strategies start paying off as soon as the relative prices of the two DLC stocks converge toward theoretical parity.", "However, since there is no identifiable date at which DLC prices will converge, arbitrage positions sometimes have to be kept open for considerable periods of time.", "In the meantime, the price gap might widen.", "In these situations, arbitrageurs may receive margin calls, after which they would most likely be forced to liquidate part of the position at a highly unfavorable moment and suffer a loss.", "Arbitrage in DLCs may be profitable, but is also very risky.A good illustration of the risk of DLC arbitrage is the position in Royal Dutch Shell—which had a DLC structure until 2005—by the hedge fund Long-Term Capital Management (LTCM, see also the discussion below).", "Lowenstein (2000) describes that LTCM established an arbitrage position in Royal Dutch Shell in the summer of 1997, when Royal Dutch traded at an 8 to 10 percent premium.", "In total, $2.3 billion was invested, half of which was long in Shell and the other half was short in Royal Dutch (Lowenstein, p. 99).", "In the autumn of 1998, large defaults on Russian debt created significant losses for the hedge fund and LTCM had to unwind several positions.", "Lowenstein reports that the premium of Royal Dutch had increased to about 22 percent and LTCM had to close the position and incur a loss.", "According to Lowenstein (p. 234), LTCM lost $286 million in equity pairs trading and more than half of this loss is accounted for by the Royal Dutch Shell trade.", "(See further under Limits to arbitrage.", ")===Private to public equities===The market prices for privately held companies are typically viewed from a return on investment perspective (such as 25%), whilst publicly held and or exchange listed companies trade on a price to earnings ratio (P/E) (such as a P/E of 10, which equates to a 10% ROI).", "Thus, if a publicly traded company specialises in the acquisition of privately held companies, from a per-share perspective there is a gain with every acquisition that falls within these guidelines.", "E.g., Berkshire Hathaway.", "Private to public equities arbitrage is a term that can arguably be applied to investment banking in general.", "Private markets to public markets differences may also help explain the overnight windfall gains enjoyed by principals of companies that just did an initial public offering (IPO).===Regulatory arbitrage===Regulatory arbitrage \"is an avoidance strategy of regulation that is exercised as a result of a regulatory inconsistency\".", "In other words, where a regulated institution takes advantage of the difference between its real (or economic) risk and the regulatory position.", "For example, if a bank, operating under the Basel I accord, has to hold 8% capital against default risk, but the real risk of default is lower, it is profitable to securitise the loan, removing the low-risk loan from its portfolio.", "On the other hand, if the real risk is higher than the regulatory risk then it is profitable to make that loan and hold on to it, provided it is priced appropriately.", "Regulatory arbitrage can result in parts of entire businesses being unregulated as a result of the arbitrage.This process can increase the overall riskiness of institutions under a risk insensitive regulatory regime, as described by Alan Greenspan in his October 1998 speech on The Role of Capital in Optimal Banking Supervision and Regulation.The term \"Regulatory Arbitrage\" was used for the first time in 2005 when it was applied by Scott V. Simpson, a partner at law firm Skadden, Arps, to refer to a new defence tactic in hostile mergers and acquisitions where differing takeover regimes in deals involving multi-jurisdictions are exploited to the advantage of a target company under threat.In economics, regulatory arbitrage (sometimes, tax arbitrage) may refer to situations when a company can choose a nominal place of business with a regulatory, legal or tax regime with lower costs.", "This can occur particularly where the business transaction has no obvious physical location.", "In the case of many financial products, it may be unclear \"where\" the transaction occurs.Regulatory arbitrage can include restructuring a bank by outsourcing services such as IT.", "The outsourcing company takes over the installations, buying out the bank's assets and charges a periodic service fee back to the bank.", "This frees up cashflow usable for new lending by the bank.", "The bank will have higher IT costs, but counts on the multiplier effect of money creation and the interest rate spread to make it a profitable exercise.Example:Suppose the bank sells its IT installations for US$40 million.", "With a reserve ratio of 10%, the bank can create US$400 million in additional loans (there is a time lag, and the bank has to expect to recover the loaned money back into its books).", "The bank can often lend (and securitize the loan) to the IT services company to cover the acquisition cost of the IT installations.", "This can be at preferential rates, as the sole client using the IT installation is the bank.", "If the bank can generate 5% interest margin on the 400 million of new loans, the bank will increase interest revenues by 20 million.", "The IT services company is free to leverage their balance sheet as aggressively as they and their banker agree to.", "This is the reason behind the trend towards outsourcing in the financial sector.", "Without this money creation benefit, it is actually more expensive to outsource the IT operations as the outsourcing adds a layer of management and increases overhead.According to PBS ''Frontline'''s 2012 four-part documentary, \"Money, Power, and Wall Street\", regulatory arbitrage, along with asymmetric bank lobbying in Washington and abroad, allowed investment banks in the pre- and post-2008 period to continue to skirt laws and engage in the risky proprietary trading of opaque derivatives, swaps, and other credit-based instruments invented to circumvent legal restrictions at the expense of clients, government, and publics.Due to the Affordable Care Act's expansion of Medicaid coverage, one form of Regulatory Arbitrage can now be found when businesses engage in \"Medicaid Migration\", a maneuver by which qualifying employees who would typically be enrolled in company health plans elect to enroll in Medicaid instead.", "These programs that have similar characteristics as insurance products to the employee, but have radically different cost structures, resulting in significant expense reductions for employers.===Telecom arbitrage===Telecom arbitrage companies allow phone users to make international calls for free through certain access numbers.", "Such services are offered in the United Kingdom; the telecommunication arbitrage companies get paid an interconnect charge by the UK mobile networks and then buy international routes at a lower cost.", "The calls are seen as free by the UK contract mobile phone customers since they are using up their allocated monthly minutes rather than paying for additional calls.Such services were previously offered in the United States by companies such as FuturePhone.com.", "These services would operate in rural telephone exchanges, primarily in small towns in the state of Iowa.", "In these areas, the local telephone carriers are allowed to charge a high \"termination fee\" to the caller's carrier in order to fund the cost of providing service to the small and sparsely populated areas that they serve.", "However, FuturePhone (as well as other similar services) ceased operations upon legal challenges from AT&T and other service providers.===Statistical arbitrage===Statistical arbitrage is an imbalance in expected nominal values.", "A casino has a statistical arbitrage in every game of chance that it offers, referred to as the house advantage, house edge, vigorish, or house vigorish.=== Gray market ===To accomplish arbitrage, the grey market buys items through marketing channels that sell them without the permission of the product trademark owner and sells them in the legitimate market.A Swiss watch sold by an approved dealer for £42,600 is an excellent example of a grey market product; customers can buy the identical watch for £27,227 on the Chrono24 website, which is an unlicensed 'grey market.'" ], [ "The fall of Long-Term Capital Management", "Long-Term Capital Management (LTCM) lost 4.6 billion U.S. dollars in fixed income arbitrage in September 1998.LTCM had attempted to make money on the price difference between different bonds.", "For example, it would sell U.S. Treasury securities and buy Italian bond futures.", "The concept was that because Italian bond futures had a less liquid market, in the short term Italian bond futures would have a higher return than U.S. bonds, but in the long term, the prices would converge.", "Because the difference was small, a large amount of money had to be borrowed to make the buying and selling profitable.The downfall in this system began on August 17, 1998, when Russia defaulted on its ruble debt and domestic dollar debt.", "Because global markets were already nervous due to the 1997 Asian financial crisis, investors began selling non-U.S. treasury debt and buying U.S. treasuries, which were considered a safe investment.", "As a result, the price on US treasuries began to increase and the return began decreasing because there were many buyers, and the return (yield) on other bonds began to increase because there were many sellers (i.e.", "the price of those bonds fell).", "This caused the difference between the prices of U.S. treasuries and other bonds to increase, rather than to decrease as LTCM was expecting.", "Eventually this caused LTCM to fold, and their creditors had to arrange a bail-out.", "More controversially, officials of the Federal Reserve assisted in the negotiations that led to this bail-out, on the grounds that so many companies and deals were intertwined with LTCM that if LTCM actually failed, they would as well, causing a collapse in confidence in the economic system.", "Thus LTCM failed as a fixed income arbitrage fund, although it is unclear what sort of profit was realised by the banks that bailed LTCM out." ], [ "See also", "===Types of financial arbitrage===* Arbitrage betting* Covered interest arbitrage* Fixed income arbitrage* Political arbitrage* Options arbitrage* Risk arbitrage* Statistical arbitrage* Triangular arbitrage* Uncovered interest arbitrage* Volatility arbitrage===Related concepts===* Airline booking ploys* Algorithmic trading* Arbitrage pricing theory* Coherence (philosophical gambling strategy), analogous concept in Bayesian probability* Cointelation* Drop shipping* Efficient-market hypothesis* Immunization (finance)* Interest rate parity* Intermediation* No free lunch with vanishing risk* TANSTAAFL* Value investing" ], [ "Notes" ], [ "References", "*Greider, William (1997).", "''One World, Ready or Not''.", "Penguin Press.", ".", "*''Special Situation Investing: Hedging, Arbitrage, and Liquidation'', Brian J.

colours." ], [ "History", "===Foundation prior to World War II===1940–41 Fiorentina team'''Associazione Calcio Fiorentina''' was founded in the autumn of 1926 by local noble and National Fascist Party member Luigi Ridolfi Vay da Verrazzano, who initiated the merger of two older Florentine clubs, CS Firenze and PG Libertas.", "The aim of the merger was to give Florence a strong club to rival those of the more dominant Italian Football Championship sides of the time from Northwest Italy.", "Also influential was the cultural revival and rediscovery of , an ancestor of modern football that was played by members of the family.After a rough start and three seasons in lower leagues, Fiorentina reached the in 1931.That same year saw the opening of the new stadium, originally named after Giovanni Berta, a prominent fascist, but now known as Stadio Artemio Franchi.", "At the time, the stadium was a masterpiece of engineering, and its inauguration was monumental.", "To be able to compete with the best teams in Italy, Fiorentina strengthened their team with some new players, notably the Uruguayan Pedro Petrone, nicknamed ''el Artillero''.", "Despite enjoying a good season and finishing in fourth place, Fiorentina were relegated the following year, although they would return quickly to .", "In 1941, they won their first Coppa Italia, but the team were unable to build on their success during the 1940s due to World War II and other troubles.===First ''scudetto'' and '50–'60s===The first Italian champion Fiorentina, 1955–56 seasonIn 1950, Fiorentina started to achieve consistent top-five finishes in the domestic league.", "The team consisted of players such as well-known goalkeeper Giuliano Sarti, Sergio Cervato, Francesco Rosella, Guido Gratton, Giuseppe Chiappella, Aldo Scaramucci, Brazilian Julinho, and Argentinian Miguel Montuori.", "This team won Fiorentina's first ''scudetto'' (Italian championship) in 1955–56, 12 points ahead of second-place Milan.", "Milan beat Fiorentina to top spot the following year.", "Fiorentina became the first Italian team to play in a European Cup final, when a disputed penalty led to a 2–0 defeat at the hands of Alfredo Di Stéfano's Real Madrid.Fiorentina were runners-up again in the three subsequent seasons.", "In the 1960–61 season, the club won the Coppa Italia again and was also successful in Europe, winning the first Cup Winners' Cup against Scottish side Rangers.After several years of runner-up finishes, Fiorentina dropped away slightly in the 1960s, bouncing from fourth to sixth place, although the club won the Coppa Italia and the Mitropa Cup in 1966.Kurt Hamrin scored 150 goals for Fiorentina when he represented the club 1958–1967.This means that he is in second place for most goals in the club's history.===Second ''scudetto'' and '70s===While the 1960s did result in some trophies and good Serie A finishes for Fiorentina, nobody believed that the club could challenge for the title.", "The 1968–69 season started with Milan as frontrunners, but on matchday 7, they lost to Bologna and were overtaken by Gigi Riva's Cagliari.", "Fiorentina, after an unimpressive start, then moved to the top of the Serie A, but the first half of their season finished with a 2–2 draw against Varese, leaving Cagliari as outright league leader.", "The second half of the season was a three-way battle between the three contending teams, Milan, Cagliari and Fiorentina.", "Milan fell away, instead focusing their efforts on the European Cup, and it seemed that Cagliari would retain top spot.", "After Cagliari lost against , however, Fiorentina took over at the top.", "The team then won all of their remaining matches, beating rivals Juve in Turin on the penultimate matchday to seal their second,

idol to Fiorentina's fans.", "The young average age of the players led to the team being called \"''Fiorentina Ye-Ye''\".===Pontello era===In 1980, Fiorentina was bought by Flavio Pontello, who came from a rich house-building family.", "He quickly changed the team's anthem and logo, leading to some complaints by the fans, but he started to bring in high-quality players such as Francesco Graziani and Eraldo Pecci from Torino; Daniel Bertoni from Sevilla; Daniele Massaro from Monza; and a young Pietro Vierchowod from Como.", "The team was built around Giancarlo Antognoni, and in 1982, Fiorentina were involved in an exciting duel with rivals Juventus.", "After a bad injury to Antognoni, the league title was decided on the final day of the season when Fiorentina were denied a goal against Cagliari and were unable to win.", "Juventus won the title with a disputed penalty and the rivalry between the two teams erupted.The following years were strange for Fiorentina, who vacillated between high finishes and relegation battles.", "Fiorentina also bought two interesting players, ''El Puntero'' Ramón Díaz and, most significantly, the young Roberto Baggio.In 1990, Fiorentina fought

Housman" ], [ "Introduction", "'''Alfred Edward Housman''' (; 26 March 1859 – 30 April 1936) was an English classical scholar and poet.", "After an initially poor performance while at university, he took employment as a clerk in London and established his academic reputation by publishing as a private scholar at first.", "Later Housman was appointed Professor of Latin at University College London and then at the University of Cambridge.", "He is now acknowledged as one of the foremost classicists of his age and has been ranked as one of the greatest scholars of any time.", "His editions of Juvenal, Manilius, and Lucan are still considered authoritative.In 1896, he emerged as a poet with ''A Shropshire Lad'', a cycle in which he poses as an unsophisticated and melancholy youth.", "After a slow start, this captured the imagination of young readers, its preoccupation with early death appealing to them especially during times of war.", "In 1922 his ''Last Poems'' added to his reputation, which was further enhanced by the large number of song settings drawn from these collections.", "Following his death, further poems from his notebooks were published by his brother, Laurence.", "It was then too, though Housman had made no admission himself, that his sexual orientation began to be questioned." ], [ "Early life", "Valley House, Housman's birthplaceThe site of the 17th-century Fockbury House (later known as The Clock House).", "Home of Housman from 1873 to 1878Home of Housman from 1860 to 1873 and again from 1878 to 1882.His younger brother Laurence was born here in 1865.The eldest of seven children, Housman was born at Valley House in Fockbury, a hamlet on the outskirts of Bromsgrove in Worcestershire, to Sarah Jane (née Williams, married 17 June 1858 in Woodchester, Gloucester) and Edward Housman (whose family came from Lancaster), and was baptised on 24 April 1859 at Christ Church, in Catshill.", "His mother died on his twelfth birthday, and his father, a country solicitor, then married an elder cousin, Lucy, in 1873.Two of his siblings became prominent writers, sister Clemence Housman and brother Laurence Housman.Housman was educated at King Edward's School in Birmingham and later Bromsgrove School, where he revealed his academic promise and won prizes for his poems.", "In 1877, he won an open scholarship to St John's College, Oxford, and went there to study classics.", "Although introverted by nature, Housman formed strong friendships with two roommates, Moses John Jackson (1858 – 14 January 1923) and A. W. Pollard.", "Though Housman obtained a first in classical Moderations in 1879, his dedication to textual analysis led him to neglect the ancient history and philosophy that formed part of the Greats curriculum.", "Accordingly, he failed his Finals and had to return humiliated in Michaelmas term to resit the exam and at least gain a lower-level pass degree.", "Though some attribute Housman's unexpected performance in his exams directly to his unrequited feelings for Jackson, most biographers adduce more obvious causes.", "Housman was indifferent to philosophy and overconfident in his exceptional gifts, and he spent too much time with his friends.", "He may also have been distracted by news of his father's desperate illness.After Oxford, Jackson went to work as a clerk in the Patent Office in London and arranged a job there for Housman too.", "The two shared a flat with Jackson's brother Adalbert until 1885, when Housman moved to lodgings of his own, probably after Jackson responded to a declaration of love by telling Housman that he could not reciprocate his feelings.", "Two years later, Jackson moved to India, placing more distance between himself and Housman.", "When he returned briefly to England in 1889, to marry, Housman was not invited to the wedding and knew nothing about it until the couple had left the country.", "Adalbert Jackson died in 1892 and Housman commemorated him in a poem published as \"XLII – A.J.J.\"", "of ''More Poems'' (1936).Meanwhile, Housman pursued his classical studies independently, and published scholarly articles on Horace, Propertius, Ovid, Aeschylus, Euripides and Sophocles.", "He also completed an edition of Propertius, which however was rejected by both Oxford University Press and Macmillan in 1885, and was destroyed after his death.", "He gradually acquired such a high reputation that in 1892 he was offered and accepted the professorship of Latin at University College London (UCL).", "When, during his tenure, an immensely rare Coverdale Bible of 1535 was discovered in the UCL library and presented to the Library Committee, Housman (who had become an atheist while at Oxford) remarked that it would be better to sell it to \"buy some really useful books with the proceeds\"." ], [ "Later life", "Although Housman's early work and his responsibilities as a professor included both Latin and Greek, he began to specialise in Latin poetry.", "When asked later why he had stopped writing about Greek verse, he responded, \"I found that I could not attain to excellence in both.\"", "In 1911 he took the Kennedy Professorship of Latin at Trinity College, Cambridge, where he remained for the rest of his life.", "Between 1903 and 1930, Housman published his critical edition of Manilius's ''Astronomicon'' in five volumes.", "He also edited Juvenal (1905) and Lucan (1926).", "G. P. Goold, Classics Professor at University College, wrote of his predecessor's accomplishments that \"the legacy of Housman's scholarship is a thing of permanent value; and that value consists less in obvious results, the establishment of general propositions about Latin and the removal of scribal mistakes, than in the shining example he provides of a wonderful mind at work … He was and may remain the last great textual critic\".", "In the eyes of Harry Eyres, however, Housman was \"famously dry\" as a professor, and his influence led to a scholarly style in the study of literature and poetry that was philological and without emotion.", "Housman's grave markerMany colleagues were unnerved by Housman's scathing attacks on those he thought guilty of shoddy scholarship.", "In his paper \"The Application of Thought to Textual Criticism\" (1921) he wrote: \"A textual critic engaged upon his business is not at all like Newton investigating the motion of the planets: he is much more like a dog hunting for fleas\".", "He declared many of his contemporary scholars to be stupid, lazy, vain, or all three, saying: \"Knowledge is good, method is good, but one thing beyond all others is necessary; and that is to have a head, not a pumpkin, on your shoulders, and brains, not pudding, in your head\".His younger colleague, A. S. F. Gow, quoted examples of these attacks, noting that they \"were often savage in the extreme\".", "Gow also related how Housman intimidated students, sometimes reducing the women to tears.", "According to Gow, Housman could never remember the names of female students, maintaining that \"had he burdened his memory by the distinction between Miss Jones and Miss Robinson, he might have forgotten that between the second and fourth declension\".", "Among the more notable students at his Cambridge lectures was Enoch Powell, one of whose own Classical emendations was later complimented by Housman.Housman's grave at St Laurence's Church in LudlowIn his private life, Housman enjoyed country walks, gastronomy, air travel and making frequent visits to France, where he read \"books which were banned in Britain as pornographic\" but he struck A. C. Benson, a fellow don, as being \"descended from a long line of maiden aunts\".", "His feelings about his poetry were ambivalent and he certainly treated it as secondary to his scholarship.", "He did not speak in public about his poems until 1933, when he gave a lecture \"The Name and Nature of Poetry\", arguing there that poetry should appeal to emotions rather than to the intellect.Housman died, aged 77, in Cambridge.", "His ashes are buried just outside St Laurence's Church, Ludlow.", "A cherry tree was planted there in his memory (see ''A Shropshire Lad'' II) and replaced by the Housman Society in 2003 with a new cherry tree nearby." ], [ "Poetry", "===''A Shropshire Lad''===During his years in London, Housman completed ''A Shropshire Lad'', a cycle of 63 poems.", "After one publisher had turned it down, he helped subsidise its publication in 1896.At first selling slowly, it rapidly became a lasting success.", "Its appeal to English musicians had helped to make it widely known before World War I, when its themes struck a powerful chord with English readers.", "The book has been in print continuously since May 1896.The poems are marked by pessimism and preoccupation with death, without religious consolation (Housman had become an atheist while still an undergraduate).", "Housman wrote many of them while living in Highgate, London, before ever visiting Shropshire, which he presented in an idealised pastoral light as his 'land of lost content'.", "Housman himself acknowledged that \"No doubt I have been unconsciously influenced by the Greeks and Latins, but the chief sources of which I am conscious are Shakespeare's songs, the Scottish Border ballads, and Heine\".===Later collections===Housman began collecting a new set of poems after the First World War.", "His early work was an influence on many British poets who became famous by their writing about the war, and he wrote several poems as occasional verse to commemorate the war dead.", "This included his ''Epitaph on an Army of Mercenaries'', honouring the British Expeditionary Force, an elite but small force of professional soldiers sent to Belgium at the start of the war.", "In the early 1920s, when Moses Jackson was dying in Canada, Housman wanted to assemble his best unpublished poems so that Jackson could read them before his death.", "These later poems, mostly written before 1910, show a greater variety of subject and form than those in ''A Shropshire Lad'' but lack its consistency.", "He published his new collection as ''Last Poems'' (1922), feeling that his inspiration was exhausted and that he should not publish more in his lifetime.After Housman's death in 1936, his brother, Laurence published further poems in ''More Poems'' (1936), ''A.", "E .H.", ": Some Poems, Some Letters and a Personal Memoir by his Brother'' (1937), and ''Collected Poems'' (1939).", "''A.", "E. H.'' includes humorous verse such as a parody of Longfellow's poem ''Excelsior''.", "Housman also wrote a parodic ''Fragment of a Greek Tragedy'', in English, published posthumously with humorous poems under the title ''Unkind to Unicorns''.John Sparrow quoted a letter written late in Housman's life that described the genesis of his poems:Sparrow himself adds, \"How difficult it is to achieve a satisfactory analysis may be judged by considering the last poem in ''A Shropshire Lad''.", "Of its four stanzas, Housman tells us that two were 'given' him ready made; one was coaxed forth from his subconsciousness an hour or two later; the remaining one took months of conscious composition.", "No one can tell for certain which was which.", "\"===''De Amicitia'' (Of Friendship)===In 1942, Laurence Housman also deposited an essay entitled \"A. E. Housman's 'De Amicitia'\" in the British Library, with the proviso that it was not to be published for 25 years.", "The essay discussed A. E. Housman's homosexuality and his love for Moses Jackson.", "Despite the conservative nature of the times and his own caution in public life, Housman was quite open in his poetry, and especially in ''A Shropshire Lad'', about his deeper sympathies.", "Poem XXX of that sequence, for instance, speaks of how \"Fear contended with desire\": \"Others, I am not the first, / Have willed more mischief than they durst\".", "In ''More Poems'', he buries his love for Moses Jackson in the very act of commemorating it, as his feelings of love are not reciprocated and must be carried unfulfilled to the grave:Moses Jackson (1858–1923) as an undergraduate c. 1880His poem \"Oh who is that young sinner with the handcuffs on his wrists?", "\", written after the trial of Oscar Wilde, addressed more general attitudes towards homosexuals.", "In the poem the prisoner is suffering \"for the colour of his hair\", a natural quality that, in a coded reference to homosexuality, is reviled as \"nameless and abominable\" (recalling the legal phrase ''peccatum illud horribile, inter Christianos non nominandum'', \"that horrible sin, not to be named amongst Christians\")." ], [ "Musical settings", "Housman's poetry, especially ''A Shropshire Lad'', was set to music by many British, and in particular English, composers in the first half of the 20th century.", "The national, pastoral and traditional elements of his style resonated with similar trends in English music.", "In 1904, the cycle ''A Shropshire Lad'' was set by Arthur Somervell, who in 1898 had begun to develop the concept of the English song-cycle in his version of Tennyson's \"Maud\".", "Stephen Banfield believes it was acquaintance with Somervell's cycle that led other composers to set Housman: Ralph Vaughan Williams is likely to have attended the first performance at the Aeolian Hall on 3 February 1905.His well-known cycle of six songs ''On Wenlock Edge'', for string quartet, tenor and piano, was published in 1909.Between 1909 and 1911, George Butterworth produced settings in two collections, ''Six Songs from A Shropshire Lad'' and ''Bredon Hill and Other Songs''.", "He also wrote the orchestral tone poem ''A Shropshire Lad'', first performed at Leeds Festival in 1912.Ivor Gurney was another composer who made renowned settings of Housman's poems.", "Towards the end of World War I, he was working on his cycle ''Ludlow and Teme'', for voice and string quartet (published in 1919), and went on to compose the eight-song cycle ''The Western Playland'' in 1921.One more who set Housman songs during this period was John Ireland in the song cycle, ''The Land of Lost Content'' (192021).", "Charles Wilfred Orr produced 24 Housman settings in songs and song cycles composed from the 1920s into the 1950s.", "Even composers not directly associated with the 'pastoral' tradition, such as Arnold Bax, Lennox Berkeley and Arthur Bliss, were attracted to Housman's poetry.", "Housman's attitude to musical interpretations of his poetry, and indeed to music in general, was either indifference or torment.", "He told his friend Percy Withers that he knew nothing of music and it meant nothing to him.", "Withers once played him a record of the Vaughan Williams setting, but realised he had made a mistake when he saw the look of disgust on the poet's face.", "Nevertheless, by 1976, a catalogue listed 400 musical settings of Housman's poems.", "As of 2023, Lieder Net Archive records 646 settings of 188 texts." ], [ "Commemorations", "The earliest commemoration of Housman was in the chapel of Trinity College in Cambridge, where there is a memorial brass on the south wall.", "The Latin inscription was composed by his colleague there, A. S. F. Gow, who was also the author of a biographical and bibliographical sketch published immediately following his death.", "Translated into English, the memorial reads:Housman statue in BromsgroveFrom 1947, University College London's academic common room was dedicated to his memory as the Housman Room.", "Blue plaques followed later elsewhere, the first being on Byron Cottage in Highgate in 1969, recording the fact that ''A Shropshire Lad'' was written there.", "More followed, placed on his Worcestershire birthplace, his homes and school in Bromsgrove.", "The latter were encouraged by the Housman Society, which was founded in the town in 1973.Another initiative was the statue in Bromsgrove High Street, showing the poet striding with walking stick in hand.", "The work of local sculptor Kenneth Potts, it was unveiled on 22 March 1985.The blue plaques in Worcestershire were set up on the centenary of ''A Shropshire Lad'' in 1996.In September of the same year, a memorial window lozenge was dedicated at Poets' Corner in Westminster Abbey The following year saw the première of Tom Stoppard's play ''The Invention of Love'', whose subject is the relationship between Housman and Moses Jackson.As the 150th anniversary of his birth approached, London University inaugurated its Housman lectures on classical subjects in 2005, initially given every second year then annually after 2011.The anniversary itself in 2009 saw the publication of a new edition of ''A Shropshire Lad'', including pictures from across Shropshire taken by local photographer Gareth Thomas.", "Among other events, there were performances of Vaughan Williams' ''On Wenlock Edge'' and Gurney's ''Ludlow and Teme'' at St Laurence's Church in Ludlow." ], [ "Works", "===Poetry collections===* ''A Shropshire Lad'' (1896)* ''Last Poems'' (1922, Henry Holt & Company)* ''A Shropshire Lad: Authorized Edition'' (1924, Henry Holt & Company)* ''More Poems'' (1936, Barclays)* ''Collected Poems'' (1940, Henry Holt & Company)* ''Collected Poems'' (1939); the poems included in this volume but not the three above are known as ''Additional Poems''.", "The Penguin edition of 1956 includes an introduction by John Sparrow.", "* ''Manuscript Poems: Eight Hundred Lines of Hitherto Uncollected Verse from the Author's Notebooks'', ed.", "Tom Burns Haber (1955)* ''A.", "E.

[ [ "Attribution of recent climate change" ], [ "Introduction", "Observed temperature from NASA vs the 1850–1900 average used by the IPCC as a pre-industrial baseline.", "The primary driver for increased global temperatures in the industrial era is human activity, with natural forces adding variability.Scientific studies have investigated the '''causes of climate change'''.", "They have found that the main cause and driver of recent climate change is elevated levels of greenhouse gases produced by human activities.", "Natural forces add climate variability as well.", "Based on many scientific studies, it is \"unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times.\"", "Studies on attribution have focused on changes observed during the period of instrumental temperature record, particularly in the last 50 years.", "This is the period when human activity has grown fastest and observations of the atmosphere above the surface have become available.", "Some of the main human activities that contribute to global warming are: (a) increasing atmospheric concentrations of greenhouse gases (mainly carbon dioxide), for a warming effect; (b) global changes to land surface, such as deforestation, for a warming effect; and (c) increasing atmospheric concentrations of aerosols, mainly for a cooling effect.In addition to human activities, some natural mechanisms can also cause climate change, including for example, climate oscillations (for example El Niño–Southern Oscillation (ENSO)), changes in solar activity, and volcanic activity.The IPCC's attribution of recent global warming to human activities reflects the view of the scientific community, and is also supported by 196 other scientific organizations worldwide.Four main lines of evidence support attribution of recent climate change to human activities: Firstly, a physical understanding of the climate system: greenhouse gas concentrations have increased and their warming properties are well-established.", "Secondly, there are historical estimates of past climate changes suggest that the recent changes in global surface temperature are unusual.", "Thirdly, computer-based climate models are unable to replicate the observed warming unless human greenhouse gas emissions are included.", "And finally, natural forces alone (such as solar and volcanic activity) cannot explain the observed warming.energy imbalance." ], [ "Factors affecting Earth's climate", " sources and sinks since 1880.While there is little debate that excess carbon dioxide in the industrial era has mostly come from burning fossil fuels, the future strength of land and ocean carbon sinks is an area of study.Factors affecting Earth's climate can be broken down into forcings, feedbacks and internal variations.", "A forcing is something that is imposed externally on the climate system.", "External forcings include natural phenomena such as volcanic eruptions and variations in the sun's output.", "Human activities can also impose forcings, for example, through changing the composition of Earth's atmosphere.Radiative forcing is a measure of how various factors alter the energy balance of planet Earth.", "A positive radiative forcing will lead towards a warming of the surface and, over time, the climate system.", "Between the start of the Industrial Revolution in 1750, and the year 2005, the increase in the atmospheric concentration of carbon dioxide (chemical formula: ) led to a positive radiative forcing, averaged over the Earth's surface area, of about 1.66 watts per square metre (abbreviated W m−2).Climate feedbacks can either amplify or dampen the response of the climate to a given forcing.There are many feedback mechanisms in the climate system that can either amplify (a positive feedback) or diminish (a negative feedback) the effects of a change in climate forcing.The climate system will vary in response to changes in forcings.The climate system will show internal variability both in the presence and absence of forcings imposed on it, (see images opposite).", "This internal variability is a result of complex interactions between components of the climate system, such as the coupling between the atmosphere and ocean (see also the later section on Internal climate variability and global warming).", "An example of internal variability is the El Niño–Southern Oscillation." ], [ "Main causes", "=== Greenhouse gases === is absorbed and emitted naturally as part of the carbon cycle, through animal and plant respiration, volcanic eruptions, and ocean-atmosphere exchange.", "Human activities, such as the burning of fossil fuels and changes in land use (see below), release large amounts of carbon to the atmosphere, causing concentrations in the atmosphere to rise.The high-accuracy measurements of atmospheric concentration, initiated by Charles David Keeling in 1958, constitute the master time series documenting the changing composition of the atmosphere.", "These data, known as the Keeling Curve, have iconic status in climate change science as evidence of the effect of human activities on the chemical composition of the global atmosphere.The Keeling Curve shows the long-term increase of atmospheric carbon dioxide () concentrations from 1958–2018.Monthly measurements display seasonal oscillations in an upward trend.", "Each year's maximum occurs during the Northern Hemisphere's late spring.Keeling's initial 1958 measurements showed 313 parts per million by volume (ppm).", "Atmospheric concentrations, commonly written \"ppm\", are measured in parts-per-million by volume (ppmv).", "In May 2019, the concentration of in the atmosphere reached 415 ppm.", "The last time when it reached this level was 2.6–5.3 million years ago.", "Without human intervention, it would be 280 ppm.", "Along with , methane and to a lesser extent nitrous oxide are also major forcing contributors to the greenhouse effect.", "The Kyoto Protocol lists these together with hydrofluorocarbon (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are entirely artificial gases, as contributors to radiative forcing.", "The chart at right attributes anthropogenic greenhouse gas emissions to eight main economic sectors, of which the largest contributors are power stations (many of which burn coal or other fossil fuels), industrial processes, transportation fuels (generally fossil fuels), and agricultural by-products (mainly methane from enteric fermentation and nitrous oxide from fertilizer use).Over the past 150 years human activities have released increasing quantities of greenhouse gases into the atmosphere.", "This has led to increases in mean global temperature, or global warming.", "Other human effects are relevant—for example, sulphate aerosols are believed to have a cooling effect.", "Natural factors also contribute.", "The likely range of human-induced surface-level air warming by 2010–2019 compared to levels in 1850–1900 is 0.8 °C to 1.3 °C, with a best estimate of 1.07 °C.", "This is close to the observed overall warming during that time of 0.9 °C to 1.2 °C, while temperature changes during that time were likely only ±0.1 °C due to natural forcings and ±0.2 °C due to variability in the climate.====Water vapor====Water vapor is the most abundant greenhouse gas and is the largest contributor to the natural greenhouse effect, despite having a short atmospheric lifetime (about 10 days).", "Some human activities can influence local water vapor levels.", "However, on a global scale, the concentration of water vapor is controlled by temperature, which influences overall rates of evaporation and precipitation.", "Therefore, the global concentration of water vapor is not substantially affected by direct human emissions.===Land surface changes===The rate of global tree cover loss has approximately doubled since 2001, to an annual loss approaching an area the size of Italy.Cumulative land-use change contributions to emissions, by region.Climate change is attributed to land use for two main reasons.", "Between 1750 and 2007, about two-thirds of anthropogenic emissions were produced from burning fossil fuels, and about one-third of emissions from changes in land use, primarily deforestation.", "Deforestation reduces the amount of carbon dioxide absorbed by ecosystems and releases greenhouse gases directly, which together with aerosols, exacerbate climate change.Land use drivers of climate change are sometimes indirect effects of human activity.", "For example, elephants in Africa are generally protective of slow-growing trees that are good for carbon dioxide sequestration.", "The sharply declining elephant population, due to human predation, indirectly leads to a tree population which absorbs less carbon dioxide.A second reason that climate change has been attributed to land use is that the terrestrial albedo is often altered by use, which leads to radiative forcing.", "This effect is more significant locally than globally.====Livestock and land use====More than 18% of anthropogenic greenhouse gas emissions are attributed to livestock and livestock-related activities such as deforestation and increasingly fuel-intensive farming practices.", "Specific attributions to the livestock sector include:* 9% of global anthropogenic carbon dioxide emissions* 35–40% of global anthropogenic methane emissions (chiefly due to enteric fermentation and manure)* 64% of global anthropogenic nitrous oxide emissions, chiefly due to fertilizer use.===Aerosols===With virtual certainty, scientific consensus has attributed various forms of climate change, chiefly cooling effects, to aerosols, which are small particles or droplets suspended in the atmosphere.Key sources to which anthropogenic aerosols are attributed include:* biomass burning such as slash-and-burn deforestation.", "Aerosols produced are primarily black carbon.", "* industrial air pollution, which produces soot and airborne sulfates, nitrates, and ammonium* dust produced by land use effects such as desertification" ], [ "Analytical methods", "Sun's output and volcanic eruptions, as well as natural modes of variability such as El Niño and La Niña.", "Human factors include the emissions of heat-trapping \"greenhouse\" gases and particulates as well as clearing of forests and other land-use changes.", "Figure source: NOAA NCDC.=== Detection and attribution ===This image shows three examples of internal climate variability measured between 1950 and 2012: the El Niño–Southern oscillation, the Arctic oscillation, and the North Atlantic oscillation.Detection and attribution of climate signals, as well as its common-sense meaning, has a more precise definition within the climate change literature, as expressed by the IPCC.", "Detection of a climate signal does not always imply significant attribution.", "The IPCC's Fourth Assessment Report says \"it is ''extremely likely'' that human activities have exerted a substantial net warming influence on climate since 1750\", where \"extremely likely\" indicates a probability greater than 95%.", "''Detection'' of a signal requires demonstrating that an observed change is statistically significantly different from that which can be explained by natural internal variability.", "''Attribution'' requires demonstrating that a signal is:* unlikely to be due entirely to internal variability;* consistent with the estimated responses to the given combination of anthropogenic and natural forcing* not consistent with alternative, physically plausible explanations of recent climate change that exclude important elements of the given combination of forcings.The IPCC Fourth Assessment Report (2007), concluded that attribution was possible for a number of observed changes in the climate (see effects of global warming).", "However, attribution was found to be more difficult when assessing changes over smaller regions (less than continental scale) and over short time periods (less than 50 years).Over larger regions, averaging reduces natural variability of the climate, making detection and attribution easier.=== Lines of evidence ===Among the possible factors that could produce changes in global mean temperature are internal variability of the climate system, external forcing, an increase in concentration of greenhouse gases, or any combination of these.", "Current studies indicate that the increase in greenhouse gases, most notably , is mostly responsible for the observed warming.", "Evidence for this conclusion includes:* Estimates of internal variability from climate models, and reconstructions of past temperatures, indicate that the warming is unlikely to be entirely natural.", "* Climate models forced by natural factors ''and'' increased greenhouse gases and aerosols reproduce the observed global temperature changes; those forced by natural factors alone do not.", "* \"Fingerprint\" methods (see below) indicate that the pattern of change is closer to that expected from greenhouse gas-forced change than from natural change.", "* The plateau in warming from the 1940s to 1960s can be attributed largely to sulphate aerosol cooling.Recent scientific assessments find that most of the warming of the Earth's surface over the past 50 years has been caused by human activities.", "This conclusion rests on multiple lines of evidence.", "Like the warming \"signal\" that has gradually emerged from the \"noise\" of natural climate variability, the scientific evidence for a human influence on global climate has accumulated over the past several decades, from many hundreds of studies.", "The first line of evidence is based on a physical understanding of how greenhouse gases trap heat, how the climate system responds to increases in greenhouse gases, and how other human and natural factors influence climate.", "The second line of evidence is from indirect estimates of climate changes over the last 1,000 to 2,000 years.", "These records are obtained from living things and their remains (like tree rings and corals) and from physical quantities (like the ratio between lighter and heavier isotopes of oxygen in ice cores), which change in measurable ways as climate changes.", "The third line of evidence is based on the broad, qualitative consistency between observed changes in climate and the computer model simulations of how climate would be expected to change in response to human activities.", "For example, when climate models are run with historical increases in greenhouse gases, they show gradual warming of the Earth and ocean surface, increases in ocean heat content and the temperature of the lower atmosphere, a rise in global sea level, retreat of sea ice and snow cover, cooling of the stratosphere, an increase in the amount of atmospheric water vapor, and changes in large-scale precipitation and pressure patterns.", "These and other aspects of modelled climate change are in agreement with observations.====\"Fingerprint\" studies====Human fingerprints for global warming (summary of observational evidence that human carbon dioxide emissions are causing the climate to warm).", "'''Top panel:''' Observed global average temperature change (1870— ).", "'''Bottom panel:''' Data from the Fourth National Climate Assessment is merged for display on the same scale to emphasize relative strengths of forces affecting temperature change.", "Human-caused forces have increasingly dominated.To determine the human contribution to climate change, unique \"fingerprints\" for all potential causes are developed and compared with both observed patterns and known internal climate variability.", "For example, solar forcing—whose fingerprint involves warming the entire atmosphere—is ruled out because only the lower atmosphere has warmed.", "Atmospheric aerosols produce a smaller, cooling effect.", "Other drivers, such as changes in albedo, are less impactful.Fingerprint studies exploit these unique signatures, and allow detailed comparisons of modelled and observed climate change patterns.", "Scientists rely on such studies to attribute observed changes in climate to a particular cause or set of causes.", "In the real world, the climate changes that have occurred since the start of the Industrial Revolution are due to a complex mixture of human and natural causes.", "The importance of each individual influence in this mixture changes over time.", "Therefore, climate models are used to study how individual factors affect climate.", "For example, a single factor (like greenhouse gases) or a set of factors can be varied, and the response of the modelled climate system to these individual or combined changes can thus be studied.These projections have been confirmed by observations (shown above).For example, when climate model simulations of the last century include all of the major influences on climate, both human-induced and natural, they can reproduce many important features of observed climate change patterns.", "When human influences are removed from the model experiments, results suggest that the surface of the Earth would actually have cooled slightly over the last 50 years.", "The clear message from fingerprint studies is that the observed warming over the last half-century cannot be explained by natural factors, and is instead caused primarily by human factors.===== Atmospheric fingerprints =====Another fingerprint of human effects on climate has been identified by looking at a slice through the layers of the atmosphere, and studying the pattern of temperature changes from the surface up through the stratosphere (see the section on solar activity).", "The earliest fingerprint work focused on changes in surface and atmospheric temperature.", "Scientists then applied fingerprint methods to a whole range of climate variables, identifying human-caused climate signals in the heat content of the oceans, the height of the tropopause (the boundary between the troposphere and stratosphere, which has shifted upward by hundreds of feet in recent decades), the geographical patterns of precipitation, drought, surface pressure, and the runoff from major river basins.Studies published after the appearance of the IPCC Fourth Assessment Report in 2007 have also found human fingerprints in the increased levels of atmospheric moisture (both close to the surface and over the full extent of the atmosphere), in the decline of Arctic sea ice extent, and in the patterns of changes in Arctic and Antarctic surface temperatures.=== Extreme event attribution ===Frequency of occurrence (vertical axis) of local June–July–August temperature anomalies (relative to 1951–1980 mean) for Northern Hemisphere land in units of local standard deviation (horizontal axis).", "According to Hansen ''et al.''", "(2012), the distribution of anomalies has shifted to the right as a consequence of global warming, meaning that unusually hot summers have become more common.", "This is analogous to the rolling of a dice: cool summers now cover only half of one side of a six-sided die, white covers one side, red covers four sides, and an extremely hot (red-brown) anomaly covers half of one side." ], [ "Potential causes that have been ruled out", "Scientists have investigated other possible causes of recent climate change but these have been ruled out:* The sun: changes in solar activity, solar variation (see Solar activity and climate)* Effect of cosmic rays With regards to solar variation, scientists reject the notion that the warming observed in the global mean surface temperature record since about 1850 is the result of solar variations: \"The observed rapid rise in global mean temperatures seen after 1985 cannot be ascribed to solar variability, whichever of the mechanisms is invoked and no matter how much the solar variation is amplified.", "\"The consensus position is that solar radiation may have increased by 0.12 W/m2 since 1750, compared to 1.6 W/m2 for the net

is this year's rate of inflation that was expected last year; and is this year's actual rate of inflation::where is between 0 and 1.This says that current expectations of future inflation reflect past expectations and an \"error-adjustment\" term, in which current expectations are raised (or lowered) according to the gap between actual inflation and previous expectations.", "The error-adjustment term, also called ''partial adjustment'', allows for variations in inflation rates over the previous years, especially years that have abnormally high or low rates.", ":The above term is the ''partial adjustment'' error term, this term allows for variances that occur between actual values and expected values.", "The importance of considering the error prevents over and under expecting values of in the above example inflation rates.", "The adjustment means that the expectation can tend toward the direction of the future expected value that would be closer to the actual value, this allows a prediction to be made and consideration to be added or removed so as to be accurate of the future expectation.", "This consideration or error term is what allows the predicted value to be adaptable, thus creating an equation that is ''adaptive'' of the expectation being inferred.The theory of adaptive expectations can be applied to all previous periods so that current inflationary expectations equal::where equals actual inflation years in the past.", "The adding of a time series portion to the expectation equations accounts for multiple previous years and their respective rates in forecasting like the above example of the future inflation rate.", "Thus, current expected inflation reflects a weighted average of all past inflation rates, where the weights get smaller and smaller as we move further in to the past.", "The initial previous year has the highest weighting and the subsequent years take lesser weighting the further back the equation accounts for.", "When an agent makes a forecasting error (as in incorrectly recording a value or mistyping), the stochastic shock will cause the agent to incorrectly forecast the price expectation level again even if the price level experiences no further shocks, since the previous expectations only ever incorporates part of their errors.", "The backward nature of expectation formulation and the resultant systematic errors made by agents (see cobweb model) had become unsatisfactory to economists such as John Muth, who was pivotal in the development of an alternative model of how expectations are formed, called rational expectations.", "The use of rational expectations have largely replaced adaptive expectations in macroeconomic theory since its assumptions rely on an optimal expectations approach which is consistent with economic theory.", "However, it must be stressed that confronting adaptive expectations and rational expectations aren't necessarily justified by either use, in other words, there are situations in which following the adaptive scheme is a rational response.The first use adaptive expectations hypothesis was to describe agent behavior in ''The Purchasing Power of Money'' by Irving Fisher (1911), then later used to describe models such as hyperinflation by Philip Cagan (1956).", "Adaptive expectations were instrumental in the consumption function (1957) and Phillips curve outlined by Milton Friedman.", "Friedman suggests that workers form adaptive expectations of the inflation rate, the government can easily surprise them through unexpected monetary policy changes.", "As agents are trapped by the money illusion, they are unable to correctly perceive price and wage dynamics, so based on Friedman's theory, unemployment can always be reduced through monetary expansions.", "If the government chooses to fix a low unemployment rate the result is an increasing level of inflation for an extended period of time.", "However, in this framework, it is clear why and how adaptive expectations are problematic.", "Agents are arbitrarily supposed to ignore sources of information which, otherwise, would affect their expectations.", "For example, government announcements are such sources.", "Agents are expected to modify their expectations and break with the former trends when changes in economic policy necessitate it.", "This is the reason why the theory of adaptive expectations is often regarded as a deviation from the rational tradition of economics." ], [ "See also", "*Policy ineffectiveness proposition*Problem of induction*Rational expectations*Self-fulfilling prophecy*Cobweb model*Phillips curve*Consumption function" ], [ "References", "===General references===*" ] ]

Rivers in Texas, as well as the central and eastern parts of Mexico.Growing to a maximum total length of , the Mexican tetra is of typical characin shape, with silvery, unremarkable scalation.", "Its

waters.", "Its natural diet consists of crustaceans, insects, and annelids, although in captivity it is omnivorous.The Mexican tetra has been treated as a subspecies of ''A.", "fasciatus'', but this is not widely accepted.", "Additionally, the hypogean blind cave form is sometimes recognized as a separate species, ''A.", "jordani'', but this directly contradicts phylogenetic evidence." ], [ "Blind cave form", "Blind cave fish form''A.", "mexicanus'' is famous for its blind cave form, which is known by such names as '''blind cave tetra''', '''blind tetra''' (leading to easy confusion with the Brazilian ''Stygichthys typhlops''), '''blind cave characin''' and '''blind cavefish'''.", "Depending on the exact population, cave forms can have degenerated sight or have total loss of sight and even their eyes, due to down-regulation of the protein αA-crystallin and consequent lens cell death.", "The fish in the Pachón caves have lost their eyes completely whilst the fish from the Micos cave only have limited sight.", "Cave fish and surface fish are able to produce fertile offspring.These fish can still, however, find their way around by means of their lateral lines, which are highly sensitive to fluctuating water pressure.", "Blindness in A.", "''mexicanus'' induces a disruption of early neuromast patterning, which further causes asymmetries in cranial bone structure.", "One such asymmetry is a bend in the dorsal region of their skull, which is propounded to increase water flow to the opposite side of the face, functionally enhancing sensory input and spatial mapping in the dark waters of caves.", "Scientists suggest that gene cystathionine beta synthase-a mutation restricts blood flow to cavefish eyes during a critical stage of growth so the eyes are covered by skin.Currently, about 30 cave populations are known, dispersed over three geographically distinct areas in a karst region of San Luis Potosí and far southern Tamaulipas, northeastern Mexico.", "Among the various cave population are at least three with only full cave forms (blind and without pigment), at least eleven with cave, \"normal\" and intermediate forms, and at least one with both cave and \"normal\" forms but no intermediates.", "Studies suggest at least two distinct genetic lineages occur among the blind populations, and the current distribution of populations arose by at least five independent invasions.", "Furthermore, cave populations have a very recent origin (< 20,000 years) in which blindness or reduced vision evolved convergently after surface ancestors populated several caves independently and at different times.", "This recent origin suggests that the phenotypic changes in cavefish populations, namely eye degeneration, arose as a result of the high fixation of genetic variants present in surface fish populations in a short period of time.The eyed and eyeless forms of ''A.", "mexicanus'', being members of the same species, are closely related and can interbreed making this species an excellent model organism for examining convergent and parallel evolution, regressive evolution in cave animals, and the genetic basis of regressive traits.", "This,

forms of the Mexican tetra have proven powerful subjects for scientists studying evolution.", "When the surface-dwelling ancestors of current cave populations entered the subterranean environment, the change in ecological conditions rendered their phenotype—which included many biological functions dependent on the presence of light—subject to natural selection and genetic drift.", "One of the most striking changes to evolve was the loss of eyes.", "This is referred to as a \"regressive trait\" because the surface fish that originally colonized caves possessed eyes.", "In addition to regressive traits, cave forms evolved \"constructive traits\".", "In contrast to regressive traits, the purpose or benefit of constructive traits is generally accepted.", "Active research focuses on the mechanisms driving the evolution of regressive traits, such as the loss of eyes, in ''A.", "mexicanus''.", "Recent studies have produced evidence that the mechanism may be direct selection, or indirect selection through antagonistic pleiotropy, rather than genetic drift and neutral mutation, the traditionally favored hypothesis for regressive evolution.The blind form of the Mexican tetra is different from the surface-dwelling form in a number of ways, including having unpigmented skin, having a better olfactory sense by having taste buds all over its head, and by being able to store four times more energy as fat, allowing it to deal with irregular food supplies more effectively.Darwin said of sightless fish:Modern genetics has made clear that the lack of use does not, in itself, necessitate a feature's disappearance.", "In this context, the positive genetic benefits have to be considered, i.e., what advantages are obtained by cave-dwelling tetras by losing their eyes?", "Possible explanations include:*Not developing eyes allows the individual more energy for growth but not egg production.", "However the species does use other methods to locate food and detect danger, which also consume energy that would be conserved if it had eyes or transparent eyelids.", "*There remains less chance of accidental damage and infection, since the previously useless and exposed organ is sealed with a flap of protective skin.", "It is unknown why this species did not develop transparent skin or eyelids instead, as some species of reptiles did.", "*The lack of eyes disables the \"body clock\", which is controlled by periods of light and dark, conserving energy.", "However sunlight does have minimal impact on the \"body clock\" in caves.Another likely explanation for the loss of its eyes is that of selective neutrality and genetic drift; in the dark environment of the cave, the eyes are neither advantageous nor disadvantageous and thus any genetic factors that might impair the eyes (or their development) can take hold with no consequence on the individual or species.", "Because there is no selection pressure for sight in this environment, any number of genetic abnormalities that give rise to the damage or loss of eyes could proliferate among the population with no effect on the fitness of the population.Among some creationists, the cave tetra is seen as evidence 'against' evolution.", "One argument claims this is an instance of \"devolution\"—showing an evolutionary trend of decreasing complexity.", "But evolution is a non-directional process, and while increased complexity is a common effect, there is no reason why evolution cannot tend towards simplicity if that makes an organism better suited to its environment.Inhibition of the HSP90 protein has a dramatic effect in the development of the blind tetra.===In the aquarium===The blind cave tetras seen in the aquarium trade are all based on stock collected in the Cueva Chica Cave in the southern part of the Sierra del Abra system in 1936.These were sent to an aquarium company in Texas, who soon started to distribute them to aquarists.", "Since then, these have been selectively bred for their troglomorphic traits.", "Today large numbers are bred at commercial facilities, especially in Asia.The blind cave tetra is a hardy species.", "Their lack of sight does not hinder their ability to get food.", "They prefer subdued lighting with a rocky substrate, like gravel, mimicking their natural environment.", "They become semi-aggressive as they age, and are by nature schooling fish.", "Experiments have shown that keeping these fish in bright aquarium set-ups has no effect on the development of the skin flap that forms over their eyes as they grow." ], [ "See also", "*List

implicitly provide a highly curved electric potential to induce the resultant magnification, as opposed to direct use of lensing, such as via magnetic lenses.", "Furthermore, in normal operation (as opposed to a field ionization modes) the atom probe does not utilize a secondary source to probe the sample.", "Rather, the sample is evaporated in a controlled manner (field evaporation) and the evaporated ions are impacted onto a detector, which is typically 10 to 100 cm away.The samples are required to have a needle geometry and are produced by similar techniques as TEM sample preparation electropolishing, or focused ion beam methods.", "Since 2006, commercial systems with laser pulsing have become available and this has expanded applications from metallic only specimens into semiconducting, insulating such as ceramics, and even geological materials.Preparation is done, often by hand, to manufacture a tip radius sufficient to induce a high electric field, with radii on the order of 100 nm.To conduct an atom probe experiment a very sharp needle shaped specimen is placed in an ultra high vacuum chamber.", "After introduction into the vacuum system, the sample is reduced to cryogenic temperatures (typically 20-100 K) and manipulated such that the needle's point is aimed towards an ion detector.", "A high voltage is applied to the specimen, and either a laser pulse is applied to the specimen or a voltage pulse (typically 1-2 kV) with pulse repetition rates in the hundreds of kilohertz range is applied to a counter electrode.", "The application of the pulse to the sample allows for individual atoms at the sample surface to be ejected as an ion from the sample surface at a known time.", "Typically the pulse amplitude and the high voltage on the specimen are computer controlled to encourage only one atom to ionize at a time, but multiple ionizations are possible.", "The delay between application of the pulse and detection of the ion(s) at the detector allow for the computation of a mass-to-charge ratio.Whilst the uncertainty in the atomic mass computed by time-of-flight methods in atom probe is sufficiently small to allow for detection of individual isotopes within a material this uncertainty may still, in some cases, confound definitive identification of atomic species.", "Effects such as superposition of differing ions with multiple electrons removed, or through the presence of complex species formation during evaporation may cause two or more species to have sufficiently close time-of-flights to make definitive identification impossible." ], [ "History", "=== Field ion microscopy ===Field ion microscopy is a modification of field emission microscopy where a stream of tunneling electrons is emitted from the apex of a sharp needle-like ''tip'' cathode when subjected to a sufficiently high electric field (~3-6 V/nm).", "The needle is oriented towards a phosphor screen to create a projected image of the work function at the tip apex.", "The image resolution is limited to (2-2.5 nm), due to quantum mechanical effects and lateral variations in the electron velocity.In field ion microscopy the tip is cooled by a cryogen and its polarity is reversed.", "When an ''imaging gas'' (usually hydrogen or helium) is introduced at low pressures (< 0.1 Pascal) gas ions in the high electric field at the tip apex are ''field ionized'' and produce a projected image of protruding atoms at the tip apex.", "The image resolution is determined primarily by the temperature of the tip but even at 78 Kelvin atomic resolution is

Smith at Oxford University in 1988.The Tomographic Atom Probe (TAP), developed by researchers at the University of Rouen in France in 1993, introduced a multichannel timing system and multianode array.", "Both instruments (PoSAP and TAP) were commercialized by Oxford Nanoscience and CAMECA respectively.", "Since then, there have been many refinements to increase the field of view, mass and position resolution, and data acquisition rate of the instrument.", "The Local Electrode Atom Probe was first introduced in 2003 by Imago Scientific Instruments.", "In 2005, the commercialization of the pulsed laser atom probe (PLAP) expanded the avenues of research from highly conductive materials (metals) to poor conductors (semiconductors like silicon) and even insulating materials.", "AMETEK acquired CAMECA in 2007 and Imago Scientific Instruments (Madison, WI) in 2010, making the company the sole commercial developer of APTs with more than 110 instruments installed around the world in 2019.The first few decades of work with APT focused on metals.", "However, with the introduction of the laser pulsed atom probe systems applications have expanded to semiconductors, ceramic and geologic materials, with some work on biomaterials.", "The most advanced study of biological material to date using APT involved analyzing the chemical structure of teeth of the radula of chiton ''Chaetopleura apiculata''.", "In this study, the use of APT showed chemical maps of organic fibers in the surrounding nano-crystalline magnetite in the chiton teeth, fibers which were often co-located with sodium or magnesium.", "This has been furthered to study elephant tusks, dentin and human enamel." ], [ "Theory", "=== Field evaporation ===Field evaporation is an effect that can occur when an atom bonded at the surface of a material is in the presence of a sufficiently high and appropriately directed electric field, where the electric field is the differential of electric potential (voltage) with respect to distance.", "Once this condition is met, it is sufficient that local bonding at the specimen surface is capable of being overcome by the field, allowing for evaporation of an atom from the surface to which it is otherwise bonded.=== Ion flight ===Whether evaporated from the material itself, or ionised from the gas, the ions that are evaporated are accelerated by electrostatic force, acquiring most of their energy within a few tip-radii of the sample.Subsequently, the accelerative force on any given ion is controlled by the electrostatic equation, where ''n'' is the ionisation state of the ion, and ''e'' is the fundamental electric charge.", ":This can be equated with the mass of the ion, ''m'', via Newton's law (F=ma):::Relativistic effects in the ion flight are usually ignored, as realisable ion speeds are only a very small fraction of the speed of light.Assuming that the ion is accelerated during a very short interval, the ion can be assumed to be travelling at constant velocity.", "As the ion will travel from the tip at voltage V1 to some nominal ground potential, the speed at which the ion is travelling can be estimated by the energy transferred into the ion during (or near) ionisation.", "Therefore, the ion speed can be computed with the following equation, which relates kinetic energy to energy gain due to the electric field, the negative arising from the loss of electrons forming a net positive charge.", ":Where ''U'' is the ion velocity.", "Solving for ''U'', the following relation is found::Let's say that for at a certain ionization voltage, a singly charged hydrogen ion acquires a resulting velocity of 1.4x10^6 ms−1 at 10~kV.", "A singly charged deuterium ion under the sample conditions would have acquired roughly 1.4x10^6/1.41 ms−1.If a detector was placed at a distance of 1 m, the ion flight times would be 1/1.4x10^6 and 1.41/1.4x10^6 s. Thus, the time of the ion arrival can be used to infer the ion type itself, if the evaporation time is known.From the above equation, it can be re-arranged to show that:given a known flight distance.", "F, for the ion, and a known flight time, t,:and thus one can substitute these values to obtain the mass-to-charge for the ion.", ":Thus for an ion which traverses a 1 m flight path, across a time of 2000 ns, given an initial accelerating voltage of 5000 V (V in Si units is kg.m^2.s^-3.A^-1) and noting that one amu is 1×10−27 kg, the mass-to-charge ratio (more correctly the mass-to-ionisation value ratio) becomes ~3.86 amu/charge.", "The number of electrons removed, and thus net positive charge on the ion is not known directly, but can be inferred from the histogram (spectrum) of observed ions.=== Magnification ===The magnification in an atom is due to the projection of ions radially away from the small, sharp tip.", "Subsequently, in the far-field, the ions will be greatly magnified.", "This magnification is sufficient to observe field variations due to individual atoms, thus allowing in field ion and field evaporation modes for the imaging of single atoms.The standard projection model for the atom probe is an emitter geometry that is based upon a revolution of a conic section, such as a sphere, hyperboloid or paraboloid.", "For these tip models, solutions to the field may be approximated or obtained analytically.", "The magnification for a spherical emitter is inversely proportional to the radius of the tip, given a projection directly onto a spherical screen, the following equation can be obtained geometrically.", ":Where rscreen is the radius of the detection screen from the tip centre, and rtip the tip radius.", "A practical tip to screen distances may range from several centimeters to several meters, with increased detector area required at larger to subtend the same field of view.Practically speaking, the usable magnification will be limited by several effects, such as lateral vibration of the atoms prior to evaporation.Whilst the magnification of both the field ion and atom probe microscopes is extremely high, the exact magnification is dependent upon conditions specific to the examined specimen, so unlike for conventional electron microscopes, there is often little direct control on magnification, and furthermore, obtained images may have strongly variable magnifications due to fluctuations in the shape of the electric field at the surface.=== Reconstruction ===The computational conversion of the ion sequence data, as obtained from a position-sensitive detector to a three-dimensional visualisation of atomic types, is termed \"reconstruction\".", "Reconstruction algorithms are typically geometrically based and have several literature formulations.", "Most models for reconstruction assume that the tip is a spherical object, and use empirical corrections to stereographic projection to convert detector positions back to a 2D surface embedded in 3D space, R3.By sweeping this surface through R3 as a function of the ion sequence input data, such as via ion-ordering, a volume is generated onto which positions the 2D detector positions can be computed and placed three-dimensional space.Typically the sweep takes the simple form of advancement of the surface, such that the surface is expanded in a symmetric manner about its advancement axis, with the advancement rate set by a volume attributed to each ion detected and identified.", "This causes the final reconstructed volume to assume a rounded-conical shape, similar to a badminton shuttlecock.", "The detected events thus become a point cloud data with attributed experimentally measured values, such as ion time of flight or experimentally derived quantities, e.g.", "time of flight or detector data.This form of data manipulation allows for rapid computer visualisation and analysis, with data presented as point cloud data with additional information, such as each ion's mass to charge (as computed from the velocity equation above), voltage or other auxiliary measured quantity or computation therefrom.=== Data features ===The canonical feature of atom probe data, is its high spatial resolution in the direction through the material, which has been attributed to an ordered evaporation sequence.", "This data can therefore image near atomically sharp buried interfaces with the associated chemical information.The data obtained from the evaporative process is however not without artefacts that form the physical evaporation or ionisation process.", "A key feature of the evaporation or field ion images is that the data density is highly inhomogeneous, due to the corrugation of the specimen surface at the atomic scale.", "This corrugation gives rise to strong electric field gradients in the near-tip zone (on the order of an atomic radii or less from the tip), which during ionisation deflects ions away from the electric field normal.The resultant deflection means that in these regions of high curvature, atomic terraces are belied by a strong anisotropy in the detection density.", "Where this occurs due to a few atoms on a surface is usually referred to as a \"pole\", as these are coincident with the crystallographic axes of the specimen (FCC, BCC, HCP) etc.", "Where the edges of an atomic terrace causes deflection, a low density line is formed and is termed a \"zone line\".These poles and zone-lines, whilst inducing fluctuations in data density in the reconstructed datasets, which can prove problematic during post-analysis, are critical for determining information such as angular magnification, as the crystallographic relationships between features are typically well known.When reconstructing the data, owing to the evaporation of successive layers of material from the sample, the lateral and in-depth reconstruction values are highly anisotropic.", "Determination of the exact resolution of the instrument is of limited use, as the resolution of the device is set by the physical properties of the material under analysis." ], [ "Systems", "Many designs have been constructed since the method's inception.", "Initial field ion microscopes, precursors to modern atom probes, were usually glass blown devices developed by individual research laboratories.=== System layout ===At a minimum, an atom probe will consist of several key pieces of equipment.", "* A vacuum system for maintaining the low pressures (~10−8 to 10−10 Pa) required, typically a classic 3 chambered UHV design.", "* A system for the manipulation of samples inside the vacuum, including sample viewing systems.", "* A cooling system to reduce atomic motion, such as a helium refrigeration circuit - providing sample temperatures as low as 15K.", "* A high voltage system to raise the sample standing voltage near the threshold for field evaporation.", "* A high voltage pulsing system, use to create timed field evaporation events* A counter electrode that can be a simple disk shape (like earlier generation atom probes), or a cone-shaped Local Electrode.", "The voltage pulse (negative) is typically applied to the counter electrode.", "* A detection system for single energetic ions that includes XY position and TOF information.Optionally, an atom probe may also include laser-optical systems for laser beam targeting and pulsing, if using laser-evaporation methods.", "In-situ reaction systems, heaters, or plasma treatment may also be employed for some studies as well as a pure noble gas introduction for FIM.=== Performance ===Collectable ion volumes were previously limited to several thousand, or tens of thousands of ionic events.", "Subsequent electronics and instrumentation development has increased the rate of data accumulation, with datasets of hundreds of million atoms (dataset volumes of 107 nm3).", "Data collection times vary considerably depending upon the experimental conditions and the number of ions collected.", "Experiments take from a few minutes, to many hours to complete." ], [ "Applications", "=== Metallurgy ===Atom probe has typically been employed in the chemical analysis of alloy systems at the atomic level.", "This has arisen as a result of voltage pulsed atom probes providing good chemical and sufficient spatial information in these materials.", "Metal samples from large grained alloys may be simple to fabricate, particularly from wire samples, with hand-electropolishing techniques giving good results.Subsequently, atom probe has been used in the analysis of the chemical composition of a wide range of alloys.Such data is critical in determining the effect of alloy constituents in a bulk material, identification of solid-state reaction features, such as solid phase precipitates.", "Such information may not be amenable to analysis by other means (e.g.", "TEM) owing to the difficulty in generating a three-dimensional dataset with composition.=== Semiconductors ===Semi-conductor materials are often analysable in atom probe, however sample preparation may be more difficult, and interpretation of results may be more complex, particularly if the semi-conductor contains phases which evaporate at differing electric field strengths.Applications such as ion implantation may be used to identify the distribution of dopants inside a semi-conducting material, which is increasingly critical in the correct design of modern nanometre scale electronics." ], [ "Limitations", "* Materials implicitly control achievable spatial resolution.", "* Specimen geometry during the analysis is uncontrolled, yet controls projection behaviour, hence there is little control over the magnification.", "This induces distortions into the computer generated 3D dataset.", "Features of interest might evaporate in a physically different manner to the bulk sample, altering projection geometry and the magnification of the reconstructed volume.", "This yields strong spatial distortions in the final image.", "* Volume selectability can be limited.", "Site specific preparation methods, e.g.", "using Focussed ion beam preparation, although more time-consuming, may be used to bypass such limitations.", "* Ion overlap in some samples (e.g.", "between oxygen and sulfur) resulted in ambiguous analysed species.", "This may be mitigated by selection of experiment temperature or laser input energy to influence the ionisation number (+, ++, 3+ etc.)", "of the ionised groups.", "Data analysis can be used in some cases to statistically recover overlaps.", "* Low molecular weight gases (Hydrogen & Helium) may be difficult to be removed from the analysis chamber, and may be adsorbed and emitted from the specimen, even though not present in the original specimen.", "This may also limit identification of Hydrogen in some samples.", "For this reason, deuterated samples have been used to overcome limitations.", "* Results may be contingent on the parameters used to convert the 2D detected data into 3D.", "In more problematic materials, correct reconstruction may not be done, due to limited knowledge of the true magnification; particularly if zone or pole regions cannot be observed." ], [ "References" ], [ "Further reading", "* Michael K.

police suggested to skeptical journalists that Belcastro was an independent operator.A 1929 report by ''The New York Times'' connected Capone to the 1926 murder of Assistant State Attorney William H. McSwiggin, the 1928 murders of chief investigator Ben Newmark and former mentor Frankie Yale.===Saint Valentine's Day Massacre===Capone was widely assumed to have been responsible for ordering the 1929 Saint Valentine's Day Massacre, despite being at his Florida home at the time of the massacre.", "The massacre was an attempt to eliminate Bugs Moran, head of the North Side Gang, and the motivation for the plan may have been the fact that some expensive whisky illegally imported from Canada via the Detroit River had been hijacked while it was being transported to Cook County, Illinois.Moran was the last survivor of the North Side gunmen; his succession had come about because his similarly aggressive predecessors, Weiss and Vincent Drucci, had been killed in the violence that followed the murder of original leader Dean O'Banion.To monitor their targets' habits and movements, Capone's men rented an apartment across from the trucking warehouse and garage at 2122 North Clark Street, which served as Moran's headquarters.", "On the morning of Thursday, February 14, 1929, Capone's lookouts signaled four gunmen disguised as police officers to initiate a \"police raid\".", "The ''faux'' police lined the seven victims along a wall and signaled for accomplices armed with machine guns and shotguns.", "Moran was not among the victims.", "Photos of the slain victims shocked the public and damaged Capone's image.", "Within days, Capone received a summons to testify before a Chicago grand jury on charges of federal Prohibition violations, but he claimed to be too unwell to attend.", "In an effort to clean up his image, Capone donated to charities and sponsored a soup kitchen in Chicago during the Depression.The Saint Valentine's Day Massacre led to public disquiet about Thompson's alliance with Capone and was a factor in Anton J.

decided to keep it in 1300, because it's more interesting\".", "Campbell and Tapert would read the script drafts, give Raimi their notes and he would decide which suggestions to keep and which ones to discard.===Pre-production===The initial budget was $8 million but during pre-production, it became obvious that this was not going to be enough.", "''Darkman'' was also a financial success and De Laurentiis had a multi-picture deal with Universal and so ''Army of Darkness'' became one of the films.", "The studio decided to contribute half of the film's $12 million budget.", "However, the film's ambitious scope and its extensive effects work forced Campbell, Raimi and producer Robert Tapert to put up $1 million of their collective salaries to shoot a new ending and not film a scene where a possessed woman pushes down some giant pillars.", "Visual effects supervisor William Mesa showed Raimi storyboards he had from Victor Fleming's film ''Joan of Arc'' that depicted huge battle scenes and he picked out 25 shots to use in ''Army of Darkness''.", "A storyboard artist worked closely with the director in order to blend the shots from the ''Joan of Arc'' storyboards with the battle scenes in his film.Traci Lords was among the actresses auditioning for the film, saying in 2001, \"I didn't get the part but I clicked with Bruce Campbell,\" with whom she would later work as a guest star in the TV series ''Hercules: The Legendary Journeys''.===Filming===Principal photography took place between soundstage and on-location work.", "''Army of Darkness'' was filmed in Bronson Canyon and Vasquez Rocks Natural Area Park.", "The interior shots were filmed on an Introvision stage in Hollywood.", "Raimi's use of the Introvision process was a tribute to the stop-motion animation work of Ray Harryhausen.", "Introvision uses front-projected images with live actors instead of the traditional rear projection that Harryhausen and others used.", "Introvision blended components with more realistic-looking results.", "To achieve this effect, Raimi used 60-foot-tall Scotchlite front-projection screens, miniatures and background plates.", "According to the director, the advantage of using this technique was \"the incredible amount of interaction between the background, which doesn't exist, and the foreground, which is usually your character\".Shooting began in mid-1991, and it lasted for about 100 days.", "It was a mid-summer shoot and while on location on a huge castle set that was built near Acton, California, on the edge of the Mojave Desert, the cast and crew endured very hot conditions during the day and very cold temperatures at night.", "Most of the film took place at night and the filmmakers shot most of the film during the summer when the days were longest and the nights were the shortest.", "It would take an hour and a half to light an area leaving the filmmakers only six hours left to shoot a scene.", "Money problems forced cinematographer Bill Pope to shoot only for certain hours Monday through Friday because he could not be paid his standard fee.", "Mesa shot many of the action sequences on the weekend.It was a difficult shoot for Campbell who had to learn elaborate choreography for the battle scenes, which involved him remembering a number system because the actor was often fighting opponents that were not really there.", "Mesa remembers, \"Bruce was cussing and swearing some of the time because you had to work on the number system.", "Sam would tell us to make it as complicated and hard for Bruce as possible.", "'Make him go through torture!'", "So we'd come up with these shots that were really, really difficult, and sometimes they would take thirty-seven takes\".", "Some scenes, like Evil Ash walking along the graveyard while his skeleton minions come to life, blended stop-motion animation with live-action skeleton puppets that were mechanically rigged, with prosthetics and visual effects.During the filming of a scene in which Campbell flipped a stuntman down a set of stairs, the lower part of his face contacted with a piece of armor, which resulted in him bleeding.", "Campbell was brought to a local emergency room to have the wound mended by a plastic surgeon, who, upon seeing the number of artificial cuts and slashes on Campbell's face, asked, \"Which one is it?\"", "In order to maintain the continuity of the injuries and dirt on Ash's face, the on-set makeup specialist utilized a plastic template that fit over Campbell's face.The filmmakers initially intended to reshoot the shot from ''Evil Dead II'' in which Ash and the Oldsmobile fall from the sky onto the ground of medieval England, with Campbell later stating that the reason they sought to reshoot it rather than reusing the footage from the previous film was due to \"a rights issue\".", "Campbell was initially supposed to jump from a ladder onto the ground, and the Oldsmobile dropped from its suspension on an aircraft cable attached to a crane on a nearby access road.", "However, the support legs under the crane gave out, causing the car to prematurely crash to the ground and the crane to fall off a cliff into a gravel pit.", "Campbell noted that, \"Ironically, after all the hassle, we wound up using the footage from 1986.", "\"===Post-production===While Dino De Laurentiis gave Raimi and his crew freedom to shoot the film the way they wanted, Universal took over during post-production.", "Universal was not happy with Raimi's cut, specifically its ending in which Ash wakes up in a futuristic, post-apocalyptic wasteland, as they felt it was too negative.", "A more upbeat ending was shot a month later in a lumber store in Malibu, California.", "(Raimi later noted, \"Actually, I kind of like the fact that there are two endings, that in one alternate universe Bruce is screwed, and in another universe he's some cheesy hero\".)", "Two months after principal filming was finished, a round of re-shoots began in Santa Monica and involved Ash in the windmill and the scenes with Bridget Fonda.Raimi needed $3 million to finish his film, but Universal was not willing to give him the money and delayed its release due to a dispute with De Laurentiis over the rights to the Hannibal Lecter character which Universal needed so that they could film a sequel to ''The Silence of the Lambs''.", "The matter was finally resolved, but the release date for ''Army of Darkness'' was pushed back from summer of 1992 to February 1993.For the film's poster, Universal brought Campbell in to take several reference head shots and asked him to strike a sly look on his face.", "They showed him a rough of the Frank Frazetta-like painting.", "The actor had a day to approve it or, as he was told, there would be no ad campaign for the film.", "Raimi ran into further troubles when the Motion Picture Association of America gave it an NC-17 rating for a shot of a female Deadite being killed early on in the film.", "Universal wanted a PG-13 rating, so Raimi made a few cuts and was still stuck with an R rating.", "In response, Universal turned the film over to outside film editors who cut the film to 81 minutes and another version running 87 minutes that was eventually released in theaters, still with an R rating." ], [ "Music", "Danny Elfman, who composed the score for ''Darkman'', wrote the \"March of the Dead\" theme for ''Army of Darkness''.", "After the re-shoots were completed, Joseph LoDuca, who composed the music for ''The Evil Dead'' and ''Evil Dead II'', returned to score the film.", "The composer used his knowledge of synthesizers and was able to present many cues in a mock-up form before he recorded them with the Seattle Symphony.", "A vinyl release of the score was revealed during the MondoCon in

fun enough adventure.\"", "On Metacritic, the film holds a weighted average score of 59 out of 100, based on 32 critics, indicating \"mixed or average reviews\".", "Roger Ebert gave the film two out of four stars and wrote, \"The movie isn't as funny or entertaining as ''Evil Dead II'', however, maybe because the comic approach seems recycled.\"", "In her review for ''The New York Times'', Janet Maslin wrote that \"Mr. Campbell's manly, mock-heroic posturing is perfectly in keeping with the director's droll outlook.\"", "Desson Howe, in his review for ''The Washington Post'' praised the film's style: \"Bill Pope's cinematography is gymnastic and appropriately frenetic.", "The visual and make-up effects (from artist-technicians William Mesa, Tony Gardner and others) are incredibly imaginative.\"", "However, ''Entertainment Weekly'' gave the film a \"C+\" rating and wrote, \"This spoofy cast of thousands looks a little too much like a crew of bland Hollywood extras.", "By the time ''Army of Darkness'' turns into a retread of ''Jason and the Argonauts'', featuring an army of fighting skeletons, the film has fallen into a ditch between parody and spectacle.",

[ [ "Athanasius of Alexandria" ], [ "Introduction", "'''Athanasius I of Alexandria''' ( – 2 May 373), also called '''Athanasius the Great''', '''Athanasius the Confessor''', or, among Coptic Christians, '''Athanasius the Apostolic''', was a Christian theologian and the 20th patriarch of Alexandria (as '''Athanasius I''').", "His intermittent episcopacy spanned 45 years ( – 2 May 373), of which over 17 encompassed five exiles, when he was replaced on the order of four different Roman emperors.", "Athanasius was a Church Father, the chief proponent of Trinitarianism against Arianism, and a noted Egyptian Christian leader of the fourth century.Conflict with Arius and Arianism, as well as with successive Roman emperors, shaped Athanasius' career.", "In 325, at age 27, Athanasius began his leading role against the Arians as a deacon and assistant to Bishop Alexander of Alexandria during the First Council of Nicaea.", "Roman Emperor Constantine the Great had convened the council in May–August 325 to address the Arian position that the Son of God, Jesus of Nazareth, is of a distinct substance from the Father.", "Three years after that council, Athanasius succeeded his mentor as Patriarch of Alexandria.", "In addition to the conflict with the Arians (including powerful and influential Arian churchmen led by Eusebius of Nicomedia), he struggled against the Emperors Constantine, Constantius II, Julian the Apostate and Valens.", "He was known as '''''Athanasius Contra Mundum''''' (Latin for 'Athanasius Against the World').Nonetheless, within a few years of his death, Gregory of Nazianzus called him the \"Pillar of the Church\".", "His writings were well regarded by subsequent Church fathers in the West and the East, who noted their devotion to the Word-become-man, pastoral concern and interest in monasticism.", "Athanasius is considered one of the four great Eastern Doctors of the Church in the Catholic Church.", "Some argue that, in his Easter letter of 367, Athanasius was the first person to list the 27 books of the New Testament canon that are in use today.", "Others argue that Origen of Alexandria was the first to list the twenty-seven books of the New Testament in his Homilies on Joshua (only there is a textual variant as to whether or not he included Revelation).", "Athanasius is venerated as a saint in the Eastern Orthodox Church, the Catholic Church, the Coptic Orthodox Church, the Anglican Communion, and Lutheranism." ], [ "Biography", "A statue of Athanasius in Catania, Sicily|alt=Athanasius was born to a Christian family in Alexandria, or possibly the nearby Nile Delta town of Damanhur, sometime between 293 and 298.The earlier date is sometimes assigned because of the maturity revealed in his two earliest treatises ''Contra Gentes'' (''Against the Heathens'') and ''De Incarnatione'' (''On the Incarnation''), which were likely written circa 318 before Arianism had begun to make itself felt, as those writings do not show an awareness of Arianism.However, Cornelius Clifford places his birth no earlier than 296 and no later than 298, based on the fact that Athanasius indicates no first-hand recollection of the Maximian persecution of 303, which he suggests Athanasius would have remembered if he had been ten years old at the time.", "Secondly, the ''Festal Epistles'' state that the Arians had accused Athanasius, among other charges, of not having yet attained the canonical age (35) and thus could not have been properly ordained as patriarch of Alexandria in 328.The accusation must have seemed plausible.", "The Orthodox Church places his year of birth around 297.=== Education ===His parents were wealthy enough to give him a fine secular education.", "He was, nevertheless, clearly not a member of the Egyptian aristocracy.", "Some Western scholars consider his command of Greek, in which he wrote most (if not all) of his surviving works, evidence that he may have been a Greek born in Alexandria.", "Historical evidence, however, indicates that he was fluent in Coptic as well, given the regions of Egypt where he preached.", "Some surviving copies of his writings are in fact in Coptic, though scholars differ as to whether he wrote them in Coptic originally (which would make him the first patriarch to do so) or whether these were translations of writings originally in Greek.Rufinus relates a story that as Bishop Alexander stood by a window, he watched boys playing on the seashore below, imitating the ritual of Christian baptism.", "He sent for the children and discovered that one of the boys (Athanasius) had acted as bishop.", "After questioning Athanasius, Bishop Alexander informed him that the baptisms were genuine, as both the form and matter of the sacrament had been performed through the recitation of the correct words and the administration of water, and that he must not continue to do this as those baptized had not been properly catechized.", "He invited Athanasius and his playfellows to prepare for clerical careers.Alexandria was the most important trade centre in the empire during Athanasius's boyhood.", "Intellectually, morally, and politically—it epitomized the ethnically diverse Graeco-Roman world, even more than Rome or Constantinople, Antioch or Marseilles.", "Its famous catechetical school, while sacrificing none of its famous passion for orthodoxy since the days of Pantaenus, Clement of Alexandria, Origen, Dionysius and Theognostus, had begun to take on an almost secular character in the comprehensiveness of its interests and had counted influential pagans among its serious auditors.Peter of Alexandria, the 17th archbishop of Alexandria, was martyred in 311 in the closing days of the Great Persecution and may have been one of Athanasius's teachers.", "His successor as bishop of Alexandria was Alexander of Alexandria.", "According to Sozomen; \"the Bishop Alexander 'invited Athanasius to be his commensal and secretary.", "He had been well educated, and was versed in grammar and rhetoric, and had already, while still a young man, and before reaching the episcopate, given proof to those who dwelt with him of his wisdom and acumen' \".", "(Soz., II, xvii)Athanasius' earliest work, ''Against the Heathen – On the Incarnation'' (written before 319), bears traces of Origenist Alexandrian thought but in an orthodox way.", "Athanasius was also familiar with the theories of various philosophical schools and in particular with the developments of neoplatonism.", "Ultimately, Athanasius would modify the philosophical thought of the School of Alexandria away from the Origenist principles such as the \"entirely allegorical interpretation of the text\".", "Still, in later works, Athanasius quotes Homer more than once (''Hist.", "Ar.", "68, Orat.", "iv.", "29'').''St.", "Athanasius'' (1883–84), by Carl Rohl-Smith, Frederik's Church, Copenhagen, Denmark|alt=Athanasius knew Greek and admitted not knowing Hebrew see, e.g., the 39th Festal Letter of St. Athan.", "The Old Testament passages he quotes frequently come from the Septuagint Greek translation.", "Only rarely did he use other Greek versions (to Aquila once in the ''Ecthesis'', to other versions once or twice on the Psalms), and his knowledge of the Old Testament was limited to the Septuagint.", "Bishop (or Patriarch, the highest ecclesial rank in the Centre of the Church, in Alexandria) Alexander ordained Athanasius a deacon in 319.In 325, Athanasius served as Alexander's secretary at the First Council of Nicaea.", "Already a recognized theologian and ascetic, he was the obvious choice to replace his ageing mentor Alexander as the Patriarch of Alexandria, despite the opposition of the followers of Arius and Meletius of Lycopolis.At length, in the Council of Nicaea, the term \"consubstantial\" (homoousion) was adopted, and a formulary of faith embodying it was drawn up by Hosius of Córdoba.", "From this time to the end of the Arian controversies, the word \"consubstantial\" continued to be the test of orthodoxy.", "The formulary of faith drawn up by Hosius is known as the Nicene Creed.", "However, \"he was not the originator of the famous 'homoousion' (ACC of ''homoousios'').", "The term had been proposed in a non-obvious and illegitimate sense by Paul of Samosata to the Fathers at Antioch, and had been rejected by them as savouring of materialistic conceptions of the Godhead.", "\"While still a deacon under Alexander's care (or early in his patriarchate as discussed below) Athanasius may have also become acquainted with some of the solitaries of the Egyptian desert, and in particular Anthony the Great, whose life he is said to have written.=== Opposition to Arianism ===In about 319, when Athanasius was a deacon, a presbyter named Arius came into a direct conflict with Alexander of Alexandria.", "It appears that Arius reproached Alexander for what he felt were misguided or heretical teachings being taught by the bishop.", "Arius' theological views appear to have been firmly rooted in Alexandrian Christianity.", "He embraced a subordinationist Christology which taught that Christ was the divine Son (Logos) of God, made, not begotten.", "This view was heavily influenced by Alexandrian thinkers like Origen and was a common Christological view in Alexandria at the time.", "Arius had support from a powerful bishop named Eusebius of Nicomedia (not to be confused with Eusebius of Caesarea), illustrating how Arius's subordinationist Christology was shared by other Christians in the empire.", "Arius was subsequently excommunicated by Alexander, and Arius began to elicit the support of many bishops who agreed with his position.=== Patriarch ===Frances A. M. Forbes writes that when Patriarch Alexander was on his death-bed he called Athanasius, who fled fearing he would be constrained to be made bishop.", "\"When the Bishops of the Church assembled to elect their new Patriarch, the whole Catholic population surrounded the church, holding up their hands to Heaven and crying; \"Give us Athanasius!\"", "The Bishops had nothing better.", "Athanasius was thus elected, as Gregory tells us...\" (Pope Gregory I had full access to the Vatican Archives).", "Alban Butler writes on the subject: \"Five months after this great Council, Nicae, St Alexander lying on his deathbed, recommended to his clergy and people the choice of Athanasius for his successor, thrice repeating his name.", "In consequence of his recommendation, the bishops of all Egypt assembled at Alexandria, and finding the people and clergy unanimous in their choice of Athanasius for patriarch, they confirmed the election about the middle of year 326.He seems, then, to have been about thirty years of age.\"T.", "Gilmartin (Professor of History, Maynooth, 1890) writes: \"On the death of Alexander, five months after the termination of the Council of Nicaea, Athanasius was unanimously elected to fill the vacant see.", "He was most unwilling to accept the dignity, for he clearly foresaw the difficulties in which it would involve him.", "The clergy and people were determined to have him as their bishop, Patriarch of Alexandria, and refused to accept any excuses.", "He at length consented to accept a responsibility that he sought in vain to escape, and was consecrated in 326, when he was about thirty years of age.", "\"Athanasius' episcopate began on 9 May 328 as the Alexandrian Council elected Athanasius to succeed after the death of Alexander.", "Patriarch Athanasius spent over 17 years in five exiles ordered by four different Roman Emperors, not counting approximately six more incidents in which Athanasius fled Alexandria to escape people seeking to take his life.", "During his first years as bishop, Athanasius visited the churches of his territory, which at that time included all of Egypt and Libya.", "He established contacts with the hermits and monks of the desert, including Pachomius, which proved very valuable to him over the years.", "\"During the forty-eight years of his episcopate, his history is told in the history of the controversies in which he was constantly engaged with the Arians, and of the sufferings he had to endure in defence of the Nicene faith.", "We have seen that when Arius was allowed to return from exile in 328, Athanasius refused to remove the sentence of excommunication.", "\"====First exile====Athanasius' first problem lay with Meletius of Lycopolis and his followers, who had failed to abide by the First Council of Nicaea.", "That council also anathematized Arius.", "Accused of mistreating Arians and Meletians, Athanasius answered those charges at a gathering of bishops at the First Synod of Tyre in 335.There, Eusebius of Nicomedia and other supporters of Arius deposed Athanasius.", "On 6 November, both sides of the dispute met with Emperor Constantine I in Constantinople.", "At that meeting, the Arians claimed Athanasius would try to cut off essential Egyptian grain supplies to Constantinople.", "He was found guilty and sent into exile to Augusta Treverorum in Gaul (now Trier in Germany).When Athanasius reached his destination in exile in 336, Maximin of Trier received him, but not as a disgraced person.", "Athanasius stayed with him for two years.", "Constantine died in 337 and was succeeded by his three sons, Constantine II, Constantius, and Constans.", "Paul I of Constantinople had cautioned Emperor Constans against the Arians, revealing their plots, and he also had been banished and found shelter with Maximin.====Second exile====Fresco at alt=Statue of the saint in St Athanasius's Catholic Church in Evanston, Illinois|alt=When Emperor Constantine I died, Athanasius was allowed to return to his See of Alexandria.", "Shortly thereafter, however, Constantius II renewed the order for Athanasius's banishment in 338.", "\"Within a few weeks he set out for Rome to lay his case before the Church at large.", "He had made his appeal to Pope Julius, who took up his cause with whole-heartedness that never wavered down to the day of that holy pontiff's death.", "The pope summoned a synod of bishops to meet in Rome.", "After a careful and detailed examination of the entire case, the primate's innocence was proclaimed to the Christian world.\"", "During this time, Gregory of Cappadocia, an Arian bishop, was installed as the patriarch of Alexandria, usurping the absent Athanasius.", "Athanasius did, however, remain in contact with his people through his annual ''Festal Letters'', in which he also announced on which date Easter would be celebrated that year.In 339 or 340, nearly one hundred bishops met at Alexandria, declared in favour of Athanasius, and vigorously rejected the criticisms of the Eusebian faction at Tyre.", "Plus, Pope Julius wrote to the supporters of Arius strongly urging Athanasius's reinstatement, but that effort proved in vain.", "Julius called a synod in Rome in 340 to address the matter, which proclaimed Athanasius the rightful bishop of Alexandria.Early in 343 Athanasius met with Hosius of Córdoba, and together they set out for Serdica.", "A full council of the Church was summoned there in deference to the Roman pontiff's wishes.", "At this great gathering of prelates, leaders of the Church, the case of Athanasius was taken up once more, that is, Athanasius was formally questioned over misdemeanours and even murder, (a bishop in Egypt named Arsenius had turned up missing, and they blamed his death on Athanasius, even supposedly producing Arsenius' severed hand.", ")The council was convoked for the purpose of inquiring into the charges against Athanasius and other bishops, on account of which they were deposed from their sees by the semi-Arian Synod of Antioch in 341 and went into exile.", "Eusebian bishops objected to the admission of Athanasius and other deposed bishops to the council, except as accused persons to answer the charges brought against them.", "Their objections were overridden by the orthodox bishops.", "The Eusebians, seeing they had no chance of having their views carried, retired to Philippopolis in Thrace where they held an opposition council under the presidency of the Patriarch of Antioch and confirmed the decrees of the Synod of Antioch.Athanasius' innocence was reaffirmed at the Council of Serdica.", "Two conciliar letters were prepared, one to the clergy and faithful of Alexandria, the other to the bishops of Egypt and Libya, in which the will of the council was made known.", "Meanwhile, the Eusebians issued an anathema against Athanasius and his supporters.", "The persecution against the orthodox party broke out with renewed vigour, and Constantius was induced to prepare drastic measures against Athanasius and the priests who were devoted to him.", "Orders were given that if Athanasius attempted to re-enter his see, he should be put to death.", "Athanasius, accordingly, withdrew from Serdica to Naissus in Mysia, where he celebrated the Easter festival of the year 344.Hosius presided over the Council of Serdica, as he did for the First Council of Nicaea, which like the 341 synod found Athanasius innocent.", "He celebrated his last Easter in exile in Aquileia in April 345, received by Bishop Fortunatianus.The Council of Serdica sent an emissary to report their finding to Constantius.", "Constantius reconsidered his decision, owing to a threatening letter from his brother Constans and the uncertain conditions of affairs on the Persian border, and he accordingly made up his mind to yield.", "But three separate letters were needed to overcome the natural hesitation of Athanasius.", "When he finally acquiesced to meet with Constantius, he was accorded a gracious interview by the emperor and sent back to his see in triumph and began ten years of peace.Pope Julius died in April 352 and was succeeded by Liberius.", "For two years Liberius had been favourable to the cause of Athanasius; but driven at last into exile, he was induced to sign an ambiguous formula, from which the great Nicene text, the \"homoousion\", had been studiously omitted.", "In 355 a council was held at Milan, where in spite of the vigorous opposition of a handful of loyal prelates among the Western bishops, a fourth condemnation of Athanasius was announced to the world.", "With his friends scattered, Hosius in exile, and Pope Liberius denounced as acquiescing in Arian formularies, Athanasius could hardly hope to escape.", "On the night of 8 February 356, while engaged in services in the Church of St. Thomas, a band of armed men burst in to secure his arrest.", "It was the beginning of his third exile.Gilmartin writes: \"By Constantius' order, the sole ruler of The Roman Empire at the death of his brother Constans, the Council of Arles in 353, was held, which was presided over by Vincent, Bishop of Capua, in the name of Pope Liberius.", "The fathers terrified of the threats of the Emperor, an avowed Arian, they consented to the condemnation of Athanasius.", "The Pope refused to accept their decision, and requested the Emperor to hold another Council, in which the charges against Athanasius could be freely investigated.", "To this Constantius consented, for he felt able to control the Council in Milan.", "\"In 355, three hundred bishops assembled in Milan, most from the West and only a few from the East.", "They met in the Church of Milan.", "Shortly, the emperor ordered them to a hall in the Imperial Palace, thus ending any free debate.", "He presented an Arian formula of faith for their acceptance.", "He threatened any who refused with exile and death.", "All, with the exception of Dionysius (bishop of Milan), and the two Papal Legates, viz., Eusebius of Vercelli and Lucifer of Cagliari, consented to the Arian Creed and the condemnation of Athanasius.", "Those who refused were sent into exile.", "The decrees were forwarded to the pope for approval but were rejected because of the violence to which the bishops were subjected.====Third exile====Athanasius at the Council of Nicea, alt=Through the influence of the Eusebian faction at Constantinople, an Arian bishop, George of Cappadocia, was appointed to rule the see of Alexandria in 356.Athanasius, after remaining some days in the neighbourhood of the city, finally withdrew into the desert of Upper Egypt where he remained for a period of six years, living the life of the monks and devoting himself to the composition of a group of writings, such as his ''Letter to the Monks'' and ''Four Orations against the Arians''.", "He also defended his own recent conduct in the ''Apology to Constantius'' and ''Apology for His Flight''.", "Constantius' persistence in his opposition to Athanasius, combined with reports Athanasius received about the persecution of non-Arians by the Arian bishop George of Laodicea, prompted Athanasius to write his more emotional ''History of the Arians'', in which he described Constantius as a precursor of the Antichrist.Constantius died on 4 November 361 and was succeeded by Julian.", "The proclamation of the new prince's accession was the signal for a pagan outbreak against the still dominant Arian faction in Alexandria.", "George, the usurping bishop, was imprisoned and murdered.", "An obscure presbyter named Pistus was chosen by the Arians to succeed him, when news arrived that filled the orthodox party with hope.", "An edict had been put forth by Julian permitting the exiled bishops of the \"Galileans\" to return to their \"towns and provinces\".", "Athanasius accordingly returned to Alexandria on 22 February 362.In 362 Athanasius convened a council at Alexandria and presided over it with Eusebius of Vercelli.", "Athanasius appealed for unity among all those who had faith in Christianity, even if they differed on matters of terminology.", "This prepared the groundwork for his definition of the orthodox doctrine of the Trinity.", "However, the council also was directed against those who denied the divinity of the Holy Spirit, the human soul of Christ, and Christ's divinity.", "Mild measures were agreed on for those heretic bishops who repented, but severe penance was decreed for the chief leaders of the major heresies.With characteristic energy he set to work to re-establish the somewhat shattered fortunes of the orthodox party and to purge the theological atmosphere of uncertainty.", "To clear up the misunderstandings that had arisen in the course of the previous years, an attempt was made to determine still further the significance of the Nicene formularies.", "In the meanwhile, Julian, who seems to have become suddenly jealous of the influence that Athanasius was exercising at Alexandria, addressed an order to Ecdicius, the Prefect of Egypt, peremptorily commanding the expulsion of the restored primate on the ground that he had not been included in the imperial act of clemency.", "The edict was communicated to the bishop by Pythicodorus Trico, who, though described in the \"Chronicon Athanasianum\" (XXXV) as a \"philosopher\", seems to have behaved with brutal insolence.", "On 23 October the people gathered about the proscribed bishop to protest against the emperor's decree; but Athanasius urged them to submit, consoling them with the promise that his absence would be of short duration.====Fourth exile====In 362 Julian, noted for his opposition to Christianity, ordered Athanasius to leave Alexandria once again.", "Athanasius left for Upper Egypt, remaining there with the Desert Fathers until Julian's death on 26 June 363.Athanasius returned in secret to Alexandria, where he received a document from the new emperor, Jovian, reinstating him once more in his episcopal functions.", "His first act was to convene a council which reaffirmed the terms of the Nicene Creed.", "Early in September 363 he set out for Antioch on the Orontes, bearing a synodal letter, in which the pronouncements of this council had been embodied.", "At Antioch he had an interview with Jovian, who received him graciously and even asked him to prepare an exposition of the orthodox faith.", "In February 364 Jovian died.====Fifth exile====The accession of Emperor Valens gave a fresh lease of life to the Arian party.", "He issued a decree banishing the bishops who had been deposed by Constantius but who had been permitted by Jovian to return to their sees.", "The news created the greatest consternation in Alexandria, and the prefect, in order to prevent a serious outbreak, gave public assurance that the very special case of Athanasius would be laid before the emperor.", "But Athanasius seems to have divined what was preparing in secret against him.", "He quietly withdrew from Alexandria in October 364 and took up his abode in a country house outside the city.", "Valens, who seems to have sincerely dreaded the possible consequences of another popular outbreak, within a few weeks issued orders allowing Athanasius to return to his episcopal see.", "Some early reports state that Athanasius spent this period of exile at his family's ancestral tomb in a Christian cemetery.====Final years and death====After returning to Alexandria, Athanasius spent his final years repairing all the damage done during the earlier years of violence, dissent, and exile.", "He resumed writing and preaching undisturbed, and characteristically re-emphasized the view of the Incarnation which had been defined at Nicaea.", "On 2 May 373, having consecrated Peter II, one of his presbyters as his successor, Athanasius died peacefully in his own bed, surrounded by his clergy and faithful supporters." ], [ "Works", "In Coptic literature, Athanasius is the first patriarch of Alexandria to use Coptic as well as Greek in his writings.=== Polemical and theological works ===Athanasius was not a speculative theologian.", "As he states in his ''First Letters to Serapion'', he held on to \"the tradition, teaching, and faith proclaimed by the apostles and guarded by the fathers.\"", "He held that both the Son of God and the Holy Spirit are consubstantial with the Father, which had a great deal of influence in the development of later doctrines regarding the Trinity.", "Athanasius' ''\"Letter Concerning the Decrees of the Council of Nicaea\"'' (''De Decretis''), is an important historical as well as theological account of the proceedings of that council.Examples of Athanasius' polemical writings against his theological opponents include ''Orations Against the Arians'', his defence of the divinity of the Holy Spirit (''Letters to Serapion'' in the 360s, and ''On the Holy Spirit''), against Macedonianism and ''On the Incarnation''.", "Athanasius also authored a two-part work, ''Against the Heathen'' and ''The Incarnation of the Word of God''.", "Completed probably early in his life, before the Arian controversy, they constitute the first classic work of developed Orthodox theology.", "In the first part, Athanasius attacks several pagan practices and beliefs.", "The second part presents teachings on the redemption.", "Also in these books, Athanasius put forward the belief, referencing , that the Son of God, the eternal Word (Logos) through whom God created the world, entered that world in human form to lead men back into the harmony from which they had earlier fallen away.His other important works include his ''Letters to Serapion'', which defends the divinity of the Holy Spirit.", "In a letter to Epictetus of Corinth, Athanasius anticipates future controversies in his defence of the humanity of Christ.", "In a letter addressed to the monk Dracontius, Athanasius urges him to leave the desert for the more active duties of a bishop.", "Athanasius also wrote several works of Biblical exegesis, primarily on Old Testament materials.", "The most important of these is his ''Epistle to Marcellinus'' (PG 27:12–45) on how to incorporate psalm-saying into one's spiritual practice.", "Perhaps his most notable letter was his Festal Letter, written to his Church in Alexandria when he was in exile, as he could not be in their presence.", "This letter clearly shows his stand that accepting Jesus as the Divine Son of God is not optional but necessary: === Biographical and ascetic works ===His biography of Anthony the Great entitled ''Life of Antony''(Βίος καὶ Πολιτεία Πατρὸς Ἀντωνίου, ''Vita Antonii'') became his most widely read work.", "Translated into several languages, it became something of a best seller in its day and played an important role in the spreading of the ascetic ideal in Eastern and Western Christianity.", "It depicts Anthony as an illiterate yet holy man who continuously engages in spiritual exercises in the Egyptian desert and struggles against demonic powers.", "It later served as an inspiration to Christian monastics in both the East and the West.", "Athanasius' works on asceticism also include a ''Discourse on Virginity'', a short work on ''Love and Self-Control'', and a treatise ''On Sickness and Health'' (of which only fragments remain).=== Misattributed works ===There are several other works ascribed to him, although not necessarily generally accepted as being his own.", "These include the so-called Athanasian Creed (which is today generally seen as being of 5th-century Galician origin), and a complete ''Expositions on the Psalms''." ], [ "Eschatology", "Based on his understanding of the prophecies of Daniel and the Book of Revelation, Athanasius described Jesus’ Second Coming in the clouds of heaven and pleads with his readers to be ready for that day, at which time Jesus would judge the earth, raise the dead, cast out the wicked, and establish his kingdom.", "Athanasius also argued that the date of Jesus’ earthly sojourn was divinely foretold beyond refutation by the seventy weeks prophecy of Daniel 9." ], [ "Veneration", "Athanasius was originally buried in Alexandria, but his remains were later transferred to the Chiesa di San Zaccaria in Venice, Italy.",

by which he has been distinguished ever since.\"", "Clifford also says: \"His career almost personifies a crisis in the history of Christianity; and he may be said rather to have shaped the events in which he took part than to have been shaped by them.\"", "St. John Henry Newman describes him as a \"principal instrument, after the Apostles, by which the sacred truths of Christianity have been conveyed and secured to the world\".The greater majority of Church leaders and the emperors fell into support for Arianism, so much so that Jerome (340–420) wrote of the period: \"The whole world groaned and was amazed to find itself Arian\".", "He, Athanasius, even suffered an unjust excommunication from Pope Liberius who was exiled and leant towards compromise, until he was allowed back to

circulate a letter after Epiphany each year confirming the date of Easter and therefore other moveable feasts.", "They also took the occasion to discuss other matters.", "Athanasius wrote forty-five festal letters.", "Athanasius' ''39th Festal Letter'', written in 367, is widely regarded as a milestone in the evolution of the canon of New Testament books.", "Some claim that Athanasius is the first person to identify the same 27 books of the New Testament that are in use today.", "Up until then, various similar lists of works to be read in churches were in use.", "Others argue that Origen of Alexandria was the first to list the twenty-seven books of the New Testament in his Homilies on Joshua (only there is a textual variant as to whether or not he included Revelation).", "Athanasius includes the Book of Baruch and the Letter of Jeremiah and places the Book of Esther among the \"7 books not in the canon but to be read\" along with the Wisdom of Solomon, Book of Sirach, Book of Judith, Book of Tobit, the ''Didache'', and ''The Shepherd of Hermas''.Athanasius' list is similar to the Codex Vaticanus in the Vatican Library.", "The establishment of the canon was not a unilateral decision by a bishop in Alexandria but the result of a process of careful investigation and deliberation, as documented in a codex of the Greek Bible and, twenty-seven years later, in his festal letter.", "Pope Damasus I, the bishop of Rome in 382, promulgated a list of books which contained a New Testament canon identical to that of Athanasius.", "A synod in Hippo in 393 repeated Athanasius' and Damasus' New Testament list (without the Epistle to the Hebrews), and the Council of Carthage (397) repeated Athanasius' and Damasus' complete New Testament list.Scholars debate whether Athanasius' list in 367 formed the basis for later lists.", "Because Athanasius' canon is the closest canon of any of the Church Fathers to the one used by Protestant churches today, many Protestants point to Athanasius as the Father of the Canon.=== Supporters ===Athanasius (left) and his supporter Cyril of Alexandria.", "17th-century depiction.Christian denominations worldwide revere Athanasius as a saint and teacher.", "They cite his defence of the Christology described in the first chapter of the Gospel of St. John and his significant theological works (C. S. Lewis calls ''On the Incarnation of the Word of God'' a \"masterpiece\") as evidence of his righteousness.", "They also emphasize his close relationship with Anthony the Great, the ancient monk who was one of the founders of the Christian monastic movement.The Gospel of St. John, and particularly the first chapter, demonstrates the Divinity of Jesus.", "This Gospel is the greatest support of Athanasius' stand.", "The Gospel of St. John's first chapter began to be said at the end of Mass, we believe as a result of Athanasius and his life's stand.", "The beginning of John's Gospel was much used as an object of special devotion throughout the Middle Ages; the practice of saying it at the altar grew, and eventually Pope Pius V made this practice universal for the Roman Rite in his 1570 edition of the Missal.", "It became a firm custom with exceptions in using another Gospel in use from 1920.Cyril of Alexandria (370–444) in the first letter says: \"Athanasius is one who can be trusted: he would not say anything that is not in accord with sacred scripture.\"", "(Ep 1).=== Critics ===Throughout most of his career, Athanasius had many detractors.", "Classics scholar Timothy Barnes recounts ancient allegations against Athanasius: from defiling an altar, to selling Church grain that had been meant to feed the poor for his own personal gain, and even violence and murder to suppress dissent.", "According to Sir Isaac Newton, Athanasius lied about the death of Arius, feigned other men's letters and denied his own, murdered the bishop Arsenius, broke a communion cup, overthrew an altar, was made bishop by violence and sedition against the canons of his own church, and was seditious and immoral.", "Athanasius used \"Arian\" to describe both followers of Arius and as a derogatory polemical term for Christians who disagreed with his formulation of the Trinity.", "Athanasius called many of his opponents \"Arian\", except for Meletius.Scholars now believe that the Arian party was not monolithic but held drastically different theological views that spanned the early Christian theological spectrum.", "They supported the tenets of Origenist thought and subordinationist theology but had little else in common.", "Moreover, many labelled \"Arian\" did not consider themselves followers of Arius.", "In addition, non-homoousian bishops disagreed with being labeled as followers of Arius, since Arius was merely a presbyter, while they were fully ordained bishops.The old allegations continue to be made against Athanasius, however, many centuries later.", "For example, Richard E. Rubenstein suggests that Athanasius ascended to the rank of bishop in Alexandria under questionable circumstances because some questioned whether he had reached the minimum age of 30 years, and further that Athanasius employed force when it suited his cause or personal interests.", "Thus, he argues that a small number of bishops who supported Athanasius held a private consecration to make him bishop." ], [ "Selected works", "* ''Athanasius.", "Contra Gentes – De Incarnatione'' (translated by Thompson, Robert W.), text and ET (Oxford: Clarendon Press, 1971).", "* ''On the Incarnation'' at theologynetwork.org* ''Letters to Serapion'' (on the Holy Spirit) at archive.org" ], [ "See also", "* Arabic Homily of Pseudo-Theophilus of Alexandria* Orthodox Christianity* Eastern Catholic Church* Eugenius of Carthage* Homoousian* Pontifical Greek College of Saint Athanasius* Saint Athanasius of Alexandria, patron saint archive" ], [ "Explanatory notes" ], [ "Citations" ], [ "General and cited sources", "* Alexander of Alexandria, \"Catholic Epistle\", ''The Ecole Initiative'', ecole.evansville.edu* Anatolios, Khaled, ''Athanasius: The Coherence of His Thought'' (New York: Routledge, 1998).", "* Arnold, Duane W.-H., ''The Early Episcopal Career of Athanasius of Alexandria'' (Notre Dame, Indiana: University of Notre Dame, 1991).", "* Arius, \"Arius's letter to Eusebius of Nicomedia\", ''Ecclesiastical History'', ed.", "Theodoret.", "Ser.", "2, Vol.", "3, 41, ''The Ecole Initiative'', ecole.evansville.edu* Attwater, Donald and Catherine Rachel John.", "''The Penguin Dictionary of Saints''.", "3rd edition.", "(New York: Penguin, 1993).", ".", "* Barnes, Timothy D., ''Athanasius and Constantius: Theology and Politics in the Constantinian Empire'' (Cambridge, Massachusetts: Harvard University Press, 1993).", "* Barnes, Timothy D., ''Constantine and Eusebius'' (Cambridge, Massachusetts: Harvard University Press, 1981)* * Brakke, David.", "''Athanasius and the Politics of Asceticism'' (1995)* Clifford, Cornelius, \"Athanasius\", ''Catholic Encyclopedia'' Vol.", "2 (1907), 35–40* Chadwick, Henry, \"Faith and Order at the Council of Nicaea\", ''Harvard Theological Review'' LIII (Cambridge Mass: Harvard University Press, 1960), 171–195.", "* Ernest, James D., ''The Bible in Athanasius of Alexandria'' (Leiden: Brill, 2004).", "* * Freeman, Charles, ''The Closing of the Western Mind: The Rise of Faith and the Fall of Reason'' (Alfred A.

[ [ "Azores" ], [ "Introduction", "The '''Azores''' ( , , ; , ), officially the '''Autonomous Region of the Azores''' (), is one of the two autonomous regions of Portugal (along with Madeira).", "It is an archipelago composed of nine volcanic islands in the Macaronesia region of the North Atlantic Ocean, about west of Lisbon, about northwest of Morocco, and about southeast of Newfoundland, Canada.Its main industries are agriculture, dairy farming, livestock, fishing, and tourism, which has become a major service activity in the region.", "In the 20th century and to some extent into the 21st, they have served as a waypoint for refueling aircraft flying between Europe and North America.", "The government of the Azores employs a large percentage of the population directly or indirectly in the service and tertiary sectors.", "The largest city of the Azores is Ponta Delgada.", "The culture, dialect, cuisine, and traditions of the Azorean islands vary considerably, because these remote islands were settled sporadically over a span of two centuries.There are nine major Azorean islands and an islet cluster, in three main groups.", "These are Flores and Corvo, to the west; Graciosa, Terceira, São Jorge, Pico, and Faial in the centre; and São Miguel, Santa Maria, and the Formigas islets to the east.", "They extend for more than and lie in a northwest–southeast direction.", "All of the islands have volcanic origins, although some, such as Santa Maria, have had no recorded activity in the time since the islands were settled several centuries ago.", "Mount Pico, on the island of Pico, is the highest point in Portugal, at .", "If measured from their base at the bottom of the ocean to their peaks, the Azores are among the tallest mountains on the planet.", "The Azores are located at the seismically active Azores Triple Junction plate boundary where the North American Plate, Eurasian Plate and Nubian Plate meet.The climate of the Azores is very mild for such a northerly location, being influenced by its distance from the continents and by the passing Gulf Stream.", "Because of the marine influence, temperatures remain mild year-round.", "Daytime temperatures normally fluctuate between depending on season.", "Temperatures above or below are unknown in the major population centres.", "It is also generally wet and cloudy." ], [ "History", "Gaspar Frutuoso wrote ''Saudades da Terra'', the first history of the Azores and Macaronesia, in the 1580s.A small number of alleged hypogea (underground structures carved into rocks) have been identified on the islands of Corvo, Santa Maria, and Terceira by Portuguese archaeologist Nuno Ribeiro, who speculated that they might date back 2,000 years, implying a human presence on the island before the Portuguese.", "These structures have been used by settlers in the Azores to store grain and the suggestion by Ribeiro that they might be burial sites is unconfirmed.", "Detailed examination and dating to authenticate the validity of these speculations is lacking; thus it is unclear whether these structures are natural or human-made and whether they predate the 15th century Portuguese colonization of the Azores.According to a 2015 paper published in ''Journal of Evolutionary Biology'', research based on mouse mitochondrial DNA points to a Scandinavian rather than Portuguese origin of the local mouse population.", "A 2021 paper published in ''Proceedings of the National Academy of Sciences'', using data from lake sediment core sampling, suggests brush-clearing was undertaken and animal husbandry introduced between 700 and 850 A.D.", "These findings suggest a brief period of Norse settlement, and the 2021 paper further cites climate simulations that suggest the dominant winds in the North Atlantic Ocean in that period blew from the northeast, which would have taken Viking ships heading southwest from Scandinavia more or less directly to the Azores.===Discovery===Under the direction of Prince Henry the Navigator, the Azores were discovered and populated in the early 1400s.The islands were known to Europeans in the 14th century; parts of them appear in the Catalan Atlas, created in 1375.In 1427, a captain sailing for Prince Henry the Navigator, possibly Gonçalo Velho, may have rediscovered the Azores, but this is not certain.", "In Thomas Ashe's 1813 work ''A History of the Azores'', the author identified a Fleming, Joshua Vander Berg of Bruges, who made landfall in the archipelago during a storm on his way to Lisbon.", "According to Ashe, the Portuguese explored the area and claimed it for Portugal.", "Other writers note the discovery of the first islands (São Miguel, Santa Maria and Terceira) by sailors in the service of Henry the Navigator, although there are few documents to support such claims.Although it is commonly said that the archipelago received its name from (Portuguese for goshawk, a common bird at the time of discovery) it is unlikely that the bird ever nested or hunted on the islands.", "There were no large animals on Santa Maria; after its discovery and before settlement began, sheep were let loose on the island to supply future settlers with food.===Early settlement===The archipelago was largely settled from mainland Portugal, but settlement did not take place right away.", "Gonçalo Velho Cabral gathered resources and settlers for the next three years (1433–1436) and sailed to establish colonies, first on Santa Maria and then on São Miguel.", "Settlers built houses, established villages and cleared bush and rocks to plant crops, grain, grapevines, sugar cane and other plants suitable for local use and for export.", "They brought domesticated animals, such as chickens, rabbits, cattle, sheep, goats and pigs.", "The settlement of the unoccupied islands started in 1439 with people mainly from the continental provinces of Algarve and Alentejo, in mainland Portugal.", "São Miguel was first settled in 1449, the settlers – mainly from the Estremadura, Alto Alentejo and Algarve areas of mainland Portugal – under the command of Gonçalo Velho Cabral, who landed at the site of modern-day Povoação.===Flemish settlers===The first reference to the island of São Jorge was made in 1439, but the date of discovery is unknown.", "In 1443, the island was already inhabited, but settlement began only after the arrival of the noble Flemish native Willem van der Haegen.", "Arriving at Topo, São Jorge, where he lived and died, he became known as Guilherme da Silveira to the islanders.", "João Vaz Corte-Real received the captaincy of the island in 1483.Velas became a town before the end of the 15th century.", "By 1490, there were 2,000 Flemings living on the islands of Terceira, Pico, Faial, São Jorge and Flores.", "Because there was such a large Flemish settlement, the Azores became known as the Flemish Islands or the Isles of Flanders.Prince Henry the Navigator was responsible for this Flemish settlement.", "His sister, Isabel, was married to Philip the Good, Duke of Burgundy, Flanders, at the time belonging to Burgundy.", "There was a revolt against Philip's rule, and disease and hunger became rampant.", "Isabel appealed to Henry to allow some of the unruly Flemings to settle in the Azores.", "He granted this and supplied them with means of transport and goods.===The 1522 earthquake and recovery===In 1522, Vila Franca do Campo, then the capital of São Miguel, was devastated by an earthquake and landslide that killed about 5,000 people, and the capital was moved to Ponta Delgada.", "The town of Vila Franca do Campo was rebuilt on the original site, and today is a thriving fishing and yachting port.", "Ponta Delgada received its city status in 1546.From the first settlement, the pioneers applied themselves to agriculture, and by the 15th century Graciosa was exporting wheat, barley, wine and brandy.", "The goods were sent to Terceira largely because of the proximity of that island.===Effects of the Portuguese succession crisis of 1580===1584 map of the Azores IslandsPortugal fell into a dynastic crisis following the death of Cardinal-King Henry of Portugal in 1580.Of the various claimants to the crown, the most powerful was king Phillip II of Spain, who justified his rights to the Portuguese throne by the fact that his mother was a Portuguese royal princess, his maternal grandfather having been King Manuel I of Portugal.", "Following his proclamation in Santarém, António, Prior of Crato was acclaimed in the Azores in 1580 (through his envoy António da Costa) but was expelled from the continent by the Spaniards following the Battle of Alcântara.", "Yet, through the administration of Cipriano de Figueiredo, governor of Terceira (who continued to govern Terceira in the name of ill-fated, former King Sebastian of Portugal), the Azoreans resisted Spanish attempts to conquer the islands (including specifically at the Battle of Salga).In 1583, Philip II of Spain, as King of Portugal, sent his fleet to clear the Azores of a combined multinational force of adventurers, mercenaries, volunteers, and soldiers who were attempting to establish the Azores as a staging post for a rival pretender to the Portuguese throne.", "Following the success of his fleet at the Battle of Ponta Delgada, captured enemies were hanged from yardarms, as they were considered pirates by Philip II.", "Opponents receiving the news variously portrayed Philip II as a despot or \"Black Legend\", the sort of insult widely made against contemporary monarchs engaged in aggressive empire building and the European wars of religion.", "Figueiredo and Violante do Canto helped organize a resistance on Terceira that influenced some of the response of the other islands, even as internal politics and support for Philip's faction increased on the other islands (including specifically on São Miguel, where the Gonçalvez da Câmara family supported the Spanish claimant).===English raids of 1589 and 1598===Battle of Terceira, part of the War of the Portuguese SuccessionAn English raid of the Azores in 1589 successfully plundered some islands and harbouring ships; eight years later, a second raid failed – the Islands Voyage.===Iberian Union===Spain held the Azores under the Iberian Union from 1580–1642 (called the \"Babylonian captivity\" in the Azores).", "The Azores were the last part of the Portuguese Empire to resist Philip's reign over Portugal (Macau resisted any official recognition), until the defeat of forces loyal to the Prior of Crato with the Conquest of the Azores in 1583.Portuguese control resumed with the end of the Iberian Union in 1640 and the beginning of the Portuguese Restoration War, not by the professional military, who were occupied with warfare on the Portuguese mainland, but by local people attacking a fortified Castilian garrison.===Overpopulation and emigration===King-Emperor Pedro IV & I planned and launched his campaign in the Liberal Wars from the Azores in name of his daughter Queen Maria IIIn the late 16th century, the Azores and Madeira began to face problems of overpopulation.", "Responding to the consequent economic problems, some people of the Azores began to emigrate to Brazil.===Liberal Wars of 1828–1834===The Portuguese Civil War (1828–1834) had strong repercussions in the Azores.", "In 1829, in Praia da Vitória, the liberals won over the absolutists, making Terceira Island the main headquarters of the new Portuguese regime and also where the Council of Regency () of Maria II of Portugal was established.", "Beginning in 1868, Portugal issued its stamps overprinted with \"\" for use in the islands.", "Between 1892 and 1906, it also issued separate stamps for the three administrative districts of the time.===Arbitrary district divisions 1836–1976===From 1836 to 1976, the archipelago was divided into three districts, equivalent (except in area) to those in the Portuguese mainland.", "The division was arbitrary and did not follow the natural island groups, rather reflecting the location of each district capital on the three main cities (none of which were on the western group).", "*'''Angra do Heroísmo''' consisted of Terceira, São Jorge, and Graciosa, with the capital at Angra do Heroísmo on Terceira.", "*'''Horta''' consisted of Pico, Faial, Flores, and Corvo, with the capital at Horta on Faial.", "*'''Ponta Delgada''' consisted of São Miguel and Santa Maria, with the capital at Ponta Delgada on São Miguel.===Modern period===Symbol of the Azorean autonomist movement in the 19th centuryIn 1931, the Azores (together with Madeira and Portuguese Guinea) revolted against the Ditadura Nacional and were held briefly by rebel military.In 1943, during World War II, the Portuguese ruler António de Oliveira Salazar leased air and naval bases in the Azores to Great Britain.", "The occupation of these facilities in October 1943 was codenamed ''Operation Alacrity'' by the British.", "This was a key turning point in the Battle of the Atlantic, enabling the Royal Air Force, the U.S. Army Air Forces, and the U.S. Navy to provide aerial coverage in the Mid-Atlantic gap.", "This helped them to protect convoys and to hunt hostile German U-boats.In 1944, the U.S. constructed a small and short-lived air base on the island of Santa Maria.", "In 1945, a new base was constructed on the island of Terceira, named Lajes Field.", "This air base is in an area called Lajes, a broad, flat sea terrace that had been a large farm.", "Lajes Field is a plateau rising out of the sea on the northeast corner of the island.", "This air base is a joint American and Portuguese venture.", "Lajes Field continues to support the American and Portuguese Armed Forces.The Azores Liberation Front's flag preceded the modern Azorean flag.During the Cold War, U.S. Navy P-3 Orion anti-submarine warfare squadrons patrolled the North Atlantic Ocean for Soviet Navy submarines and surface warships.", "Since its opening, Lajes Field has been used for refuelling American cargo planes bound for Europe, Africa, and the Middle East.", "The U.S. Navy keeps a small squadron of its ships at the harbor of Praia da Vitória, southeast of Lajes Field.", "The airfield also has a small commercial terminal handling scheduled and chartered passenger flights from the other islands in the Azores, Europe, Africa, and North America.Following the Carnation Revolution of 1974, which deposed the Estado Novo dictatorship in Lisbon, Portugal and its territories across the world entered into a period of great political uncertainty.", "The Azorean Liberation Front attempted to take advantage of this instability immediately after the revolution, hoping to establish an independent Azores, until operations ceased in 1975.In 1976, the Azores became the Autonomous Region of the Azores (), one of the autonomous regions of Portugal, and the subdistricts of the Azores were eliminated.", "In 2003, the Azores saw international attention when United States President George W. Bush, British Prime Minister Tony Blair, Spanish Prime Minister José María Aznar, and Portuguese Prime Minister José Manuel Durão Barroso held a summit there days before the commencement of the Iraq War." ], [ "Geography", "Map of the Azores+ Surface areas of the Azores Islands Island Area km2 sq mi São Miguel Pico Terceira São Jorge Faial Flores Santa Maria Graciosa Corvo The archipelago of the Azores is located in the middle of the northern hemisphere of the Atlantic Ocean and extends along a west-northwest to east-southeast orientation (between 36.5°–40° North latitudes and 24.5°–31.5° West longitudes) in an area approximately wide.", "The islands of the Azores emerged from what is called the Azores Plateau, a 5.8 million km2 region that is morphologically accented by a depth of .Azores (blue), Madeira (green) and the Canary Islands (yellow) in the northern AtlanticThe nine islands that compose the archipelago occupy a surface area of , that includes both the main islands and many islets located in their vicinities.", "They range in surface area from the largest, São Miguel, at to the smallest, Corvo, at approximately .Each of the islands has its own distinct geomorphological characteristics that make them unique:*Corvo (the smallest island) is a crater of a major Plinian eruption*Flores (its neighbor on the North American Plate) is a rugged island carved by many valleys and escarpments*Faial is characterized for its shield volcano and caldera (Caldeira Volcano)*Pico, is the highest point, at , in the Azores and continental Portugal*Graciosa is known for its active Furnas do Enxofre and mixture of volcanic cones and plains*São Jorge is a long slender island, formed from fissural eruptions over thousands of years*Terceira, almost circular, is the location of one of the largest craters in the region*São Miguel is the largest island and is pitted with many large craters and fields of spatter cones*Santa Maria – the oldest island – is heavily eroded, being one of the few places to encounter brown sandy beaches in the archipelago.These islands can be divided into three recognizable groups located on the Azores Plateau:*The Eastern Group () of São Miguel, Santa Maria and Formigas Islets*The Central Group () of Terceira, Graciosa, São Jorge, Pico and Faial*The Western Group () of Flores and Corvo.São Jorge, Pico and Faial are also collectively called (‘Islands of the Triangle’).Several sub-surface reefs (particularly the Dollabarat on the fringe of the Formigas), banks (specifically the Princess Alice Bank and D. João de Castro Bank), as well as many hydrothermal vents and sea-mounts are monitored by the regional authorities, owing to the complex geotectonic and socioeconomic significance within the economic exclusion zone of the archipelago." ], [ "Geology", "Mount Pico, the highest mountain in Portugal, displays the remnants of its last major eruption on its northern flankFrom a geostructural perspective, the Azores are located above an active triple junction between three of the world's major tectonic plates (the North American Plate, the Eurasian Plate and the African Plate), a condition that has translated into the existence of many faults and fractures in this region of the Atlantic.", "The westernmost islands of the archipelago (Corvo and Flores) are located on the North American Plate, while the remaining islands are located within the boundary that divides the Eurasian and African plates.The principal tectonic structures that exist in the region of the Azores are the Mid-Atlantic Ridge, the Terceira Rift, the Azores Fracture Zone and the Glória Fault.", "The Mid-Atlantic Ridge is the main frontier between the North American Plate and the African-Eurasian Plates that crosses the Azores Plateau between the islands of Flores and Faial from north to south then to the southwest; it is an extensive form crossed by many transform faults running perpendicular to its north–south orientation, that is seismically active and susceptible to volcanism.=== Rift and fault geology ===The Terceira Rift is a system of fractures that extends from the Mid-Atlantic Ridge to the Glória Fault that represents the main frontier between the Eurasian and African Plates.", "It is defined by a line of submarine volcanoes and island mounts that extend northwest to southeast for about , from the area west of Graciosa until the islets of the Formigas, that includes the islands of Graciosa, Terceira and São Miguel.", "Its northwest limit connects to the Mid-Atlantic Ridge, while the southeast section intersects the Gloria Fault southeast of the island of Santa Maria.The Azores Fracture Zone extends from the Glória Fault and encompasses a relatively inactive area to the south of the islands of the Central and Eastern groups north to the Terceira Rift, along a 45° angle.", "The Glória Fault, for its part, extends along a linear line from the Azores to the Azores–Gibraltar Transform Fault.=== Volcanoes ===The islands' volcanism is associated with the rifting along the Azores Triple Junction; the spread of the crust along the existing faults and fractures has produced many of the active volcanic and seismic events, while supported by buoyant upwelling in the deeper mantle, some associate with an Azores hotspot.", "Most of the volcanic activity has centered, primarily, along the Terceira Rift.From the beginning of the islands' settlement, around the 15th century, there have been 28 registered volcanic eruptions (15 terrestrial and 13 submarine).", "The last significant volcanic eruption, the Capelinhos volcano (), occurred off the coast of the island of Faial in 1957; the most recent volcanic activity occurred in the seamounts and submarine volcanoes off the coast of Serreta and in the Pico-São Jorge Channel.Algar do Carvão volcanic cave on Terceira IslandThe islands have many examples of volcano-built geomorphology including caves and lava tubes (such as the Gruta das Torres, Algar do Carvão, Gruta do Natal, Gruta das Cinco Ribeiras), the coastal lava fields (like the coast of Feteiras, Faial, the Mistério of Prainha or São João on Pico Island) in addition to the inactive cones in central São Miguel Island, the aforementioned Capelinhos on Faial, the volcanic complexes of Terceira or Plinian caldeira of Corvo Island.The islands of the archipelago were formed through volcanic and seismic activity during the Neogene Period; the first embryonic surfaces started to appear in the waters of Santa Maria during the Miocene epoch (from circa 8 million years ago).The sequence of the island formation has been generally characterized as: Santa Maria (8.12 Ma), São Miguel (4.1 Ma), Terceira (3.52 Ma), Graciosa (2.5 Ma), Flores (2.16 Ma), Faial (0.7 Ma), São Jorge (0.55 Ma), Corvo (0.7 Ma) and the youngest, Pico (0.27 Ma).", "Although all islands have experienced volcanism during their geological history, within recorded \"human settlement\" history the islands of Santa Maria, Graciosa, Flores, and Corvo have not experienced any volcanic eruptions; in addition to active fumaroles and hot-springs, the remaining islands have had sporadic eruptions since the 14th century.", "Apart from the Capelinhos volcano in 1957–1958, the last recorded instance of \"island formation\" occurred off the coast of São Miguel, when the island of Sabrina was briefly formed.=== Earthquakes ===Owing to its geodynamic environment, the region has been a center of intense seismic activity, particularly along its tectonic boundaries on the Mid-Atlantic Ridge and Terceira Rift.", "Seismic events although frequent, are usually tectonic or vulco-tectonic in nature, but in general are of low to medium intensities, occasionally punctuated by events of level 5 or greater on the Richter magnitude scale.", "The most severe earthquake was registered in 1757, near Calheta on the island of São Jorge, which exceeded 7 on the Richter magnitude scale.In comparison, the 1522 earthquake that was mentioned by historian Gaspar Frutuoso measured 6.8, but its effects were judged to be X

though the Azores look very green and sometimes wild, the vegetation has been extremely altered.", "A great part of it has been wiped out in the past 600 years for its valuable wood (for tools, buildings, boats, fire wood, and so on) and to clear land for agriculture.", "As a result, it is estimated that more than half of insects on the Graciosa island have disappeared or will become extinct.Many cultivated places (which are traditionally dedicated to pasture or to growing taro, potatoes, maize and other crops) have now been abandoned, especially as a result of emigration.", "Consequently, some invasive plants have filled these deserted and disturbed lands.", "Hydrangeas are another potential pest, but their threat is less serious.", "Notwithstanding the fact that hydrangeas were introduced from America or Asia, some locals consider them a symbol of the archipelago and propagate them along roadsides.", "''Cryptomeria'', the Japanese cedar, is a conifer extensively grown for its timber.", "The two most common of these alien species are ''Pittosporum undulatum'' and ''Hedychium gardnerianum''.", "Reforestation efforts with native laurissilva

mainland Portugal, but its location in the mid-Atlantic Ocean gives it a generally tepid, oceanic, mild to warm subtropical climate, with mild annual oscillations.===‘Azores High’ anticyclone===The Azores archipelago is located in a transition and confrontation zone between air masses of tropical origin and masses of cooler air of polar origin.", "The climate of the archipelago is largely determined by variations in the atmospheric pressure field over the North Atlantic.", "These variations conditioned by the mass of the American Continent and the Atlantic water mass are overlapped by a semi-permanent subtropical Atlantic anticyclone, commonly known as the Azores High.", "This anticyclone experiences seasonal variations which can affect the archipelago in many ways.In winter, the Azores anticyclone is positioned further south, and allows for a descent of the Polar front, approaching it to the archipelago.", "In summer, on the other hand, the anticyclone's movement further north, leads to the departure of the polar front and its associated disturbances towards higher latitudes.", "Far enough away from the mainland coasts, the continental air masses that reach the archipelago are weakened by the maritime influence.Mount Pico covered with snow.The same can not be said for the higher altitudes (e.g.", "Mount Pico), where upper air masses of a continental origin

.", "The average annual rainfall generally increases from east to west, ranging from in Santa Maria to in Flores and reaching values above on the highlands of Pico.===Köppen classification===Köppen map of AzoresUnder the Köppen climate classification, the eastern group (São Miguel and Santa Maria) is usually classified as Mediterranean while the central and western group (especially Flores and Corvo) is increasingly more humid subtropical and overall rainier because of the effects of the Gulf Stream.", "This stream has a large effect over the sea temperature which varies between in February and March, and in August and September, and increases earlier in the western group.Salvador Rivas-Martínez data presents several different bioclimatic zones for the Azores.", "Seasonal lag is extreme in the low-sun half of the year, with December being milder than April in terms of mean temperatures.", "During summer the lag is somewhat lower, with August being the warmest month, though September is usually as warm or warmer than July.=== Temperatures, humidity, and sunshine ===Although temperatures as warm as have been recorded on Pico, neither Ponta Delgada nor Angra do Heroísmo, the two largest cities, have ever been warmer than .", "There has never been a frost, snowfall, freeze or even temperatures below recorded at sea level on any of the islands.", "The coldest weather in winter usually comes from northwesterly air masses originating from Labrador in Canada.", "However, since those air masses are warmed up as they pass across the warmer Atlantic Ocean, temperatures by day even then exceed .The average relative humidity can range from 80% at the coast to over 90% above .", "However, higher elevations above the planetary boundary layer can experience extremely low values close to 10%.", "Summers are especially humid in August and may increase the perceived temperature by a few degrees.", "Winters are not only very mild but also very humid and contribute substantially to the annual precipitation.Insolation is relatively low, with 35-40% of the total possible value for sunshine, and higher in topographically lower islands such as Graciosa or Santa Maria, inversely proportional to precipitation.", "This is directly caused by the orographic lift of humid air masses and is especially pronounced in islands marked by high orography.===Hurricanes===With a greater rarity, especially in late summer and autumn, despite the northern position that the archipelago occupies, the Azores can be affected by the passage of tropical cyclones, or tropical storms derived from them, some can result from anomalies of low latitude systems while others result from the return, back to the Atlantic, after a route close to or even over the American continent.", "Though often small and in the process of dissipation, these cyclones result in many of the worst storms the archipelago is subject to.A total of 14 tropical or subtropical cyclones have affected the region in

climates in northern areas, arid areas in the \"red centre\" and semi-arid and temperate climates in southerly regions.Geographically, the Outback is unified by a combination of factors, most notably a low human population density, a largely intact natural environment and, in many places, low-intensity land uses, such as pastoralism (livestock grazing) in which production is reliant on the natural environment.", "The Outback is deeply ingrained in Australian heritage, history and folklore.", "In Australian art the subject of the Outback has been vogue, particularly in the 1940s.", "In 2009, as part of the Q150 celebrations, the Queensland Outback was announced as one of the Q150 Icons of Queensland for its role as a \"natural attraction\"." ], [ "History", "Aboriginal peoples have lived in the Outback for at least 50,000 years and occupied all Outback regions, including the driest deserts, when Europeans first entered central Australia in the 1800s.", "Many Aboriginal Australians retain strong physical and cultural links to their traditional country and are legally recognised as the Traditional Owners of large parts of the Outback under Commonwealth Native Title legislation.Early European exploration of inland Australia was sporadic.", "More focus was on the more accessible and fertile coastal areas.", "The first party to successfully cross the Blue Mountains just outside Sydney was led by Gregory Blaxland in 1813, 25 years after the colony was established.", "People, starting with John Oxley in 1817, 1818 and 1821, followed by Charles Sturt in 1829–1830, attempted to follow the westward-flowing rivers to find an \"inland sea\", but these were found to all flow into the Murray River and Darling River, which turn south.From 1858 onwards, the so-called \"Afghan\" cameleers and their beasts played an instrumental role in opening up the Outback and helping to build infrastructure.Over the period 1858 to 1861, John McDouall Stuart led six expeditions north from Adelaide, South Australia into the Outback, culminating in successfully reaching the north coast of Australia and returning without the loss of any of the party's members' lives.", "This contrasts with the ill-fated Burke and Wills expedition in 1860–61 which was much better funded, but resulted in the deaths of three of the members of the transcontinental party.The Overland Telegraph line was constructed in the 1870s along the route identified by Stuart.In 1865, the surveyor George Goyder, using changes in vegetation patterns, mapped a line in South Australia, north of which he considered rainfall to be too unreliable to support agriculture.Exploration of the Outback continued in the 1950s when Len Beadell explored, surveyed and built many roads in support of the nuclear weapons tests at Emu Field and Maralinga and rocket testing on the Woomera Prohibited Area.", "Mineral exploration continues as new mineral deposits are identified and developed.2002 was declared the Year of the

Australia, brought to Australia by pastoralists and explorers, along with the early Afghan drivers.", "Feral horses known as 'brumbies' are station horses that have run wild.", "Feral pigs, foxes, cats, goats and rabbits and other imported animals are also degrading the environment, so time and money is spent eradicating them in an attempt to help protect fragile rangelands.The Outback is home to a diverse set of animal species, such as the kangaroo, emu and dingo.", "The Dingo Fence was built to restrict movements of dingoes and wild dogs into agricultural areas towards the south east of the continent.", "The marginally fertile parts are primarily utilised as rangelands and have been traditionally used for sheep or cattle grazing, on cattle stations which are leased from the Federal Government.", "While small areas of the outback consist of clay soils the majority has exceedingly infertile palaeosols.Riversleigh, in Queensland, is one of Australia's most renowned fossil sites and

Pastoralism ===Gosses Bluff crater, one of a number of meteor impact craters that can be found across outback AustraliaThe largest industry across the Outback, in terms of the area occupied, is pastoralism, in which cattle, sheep, and sometimes goats are grazed in mostly intact, natural ecosystems.", "Widespread use of bore water, obtained from underground aquifers, including the Great Artesian Basin, has enabled livestock to be grazed across vast areas in which no permanent surface water exists naturally.Capitalising on the lack of pasture improvement and absence of fertiliser and pesticide use, many Outback pastoral properties are certified as organic livestock producers.", "In 2014, , most of which is in Outback Australia, was fully certified as organic farm production,

known as '''', during a convention in Fiuggi by dissolving into the new party in 1995.Gianfranco Fini was the leader of AN from its foundation through 2008, after being elected President of the Chamber of Deputies.", "Fini was succeeded by Ignazio La Russa, who managed the merger of the party with Forza Italia (FI) into The People of Freedom (PdL) in 2009.A group of former AN members, led by La Russa, left PdL in 2012 to launch the Brothers of Italy (FdI), while others remained in the PdL and were among the founding members of the relaunched Forza Italia (FI) in 2013." ], [ "History", "===Foundation===National Alliance was launched in 1994 when the Italian Social Movement (MSI), the former neo-fascist party, merged with conservative elements of the former Christian Democracy, which had disbanded in 1994 after two years of scandals and various splits due to political corruption at its highest levels, exposed by the ''Mani pulite'' investigation, and the Italian Liberal Party, disbanded in the same year.", "It was officially launched in January 1995.Former MSI members dominated the new party, and the MSI's last leader, Gianfranco Fini, was elected the new party's first leader.The AN logo followed a template very similar to that of the Democratic Party of the Left, incorporating the MSI logo in a small roundel of the AN logo as a means of legally preventing others from using it.", "The name was suggested by an article on the Italian newspaper ''Il Tempo'' written in 1992 by Domenico Fisichella, a prominent conservative academic.", "Starting in the 1990s, the MSI gradually transformed into a mainstream right-wing party, culminating in its 1995 dissolution into AN.===Government participation===Gianfranco Fini in 2004The party was part of all three House of Freedoms coalition governments led by Silvio Berlusconi.", "Fini was nominated Deputy Prime Minister after the 2001 Italian general election and was Foreign Minister from November 2004 to May 2006.When Fini visited Israel in late November 2003 in the function of Italian Deputy Prime Minister, he labelled the racial laws issued by the Italian fascism regime in 1938 as \"infamous\", as also Giorgio Almirante, historic leader of MSI, had done before.", "He also referred to the Italian Social Republic as belonging to the most shameful pages of the past, and considered fascism part of an era of \"absolute evil\", something which was hardly acceptable to the few remaining hardliners of the party.", "As a result, Alessandra Mussolini, the granddaughter of the former fascist dictator Benito Mussolini, who had been at odds with the party on a number of issues for a long time, and some hardliners left the party and formed Social Action.In occasion of the 2006 Italian general election, AN ran within the House of Freedoms, with new allies.", "The centre-right lost by 24,000 votes in favour of the centre-left coalition The Union.", "Individually, AN received nearly 5 million votes, amounting to 12.3%.", "In July 2007, a group of splinters led by Francesco Storace formed The Right, which was officially founded on 10 November.", "Seven MPs of AN, including Teodoro Buontempo and Daniela Santanchè, joined the new party.===The People of Freedom===In November 2007, Silvio Berlusconi announced that Forza Italia would have soon merged or transformed into The People of Freedom (PdL) party.After the sudden fall of the Prodi II Cabinet in January 2008, the break-up of The Union and the subsequent political crisis which led to a fresh general election, Berlusconi hinted that Forza Italia would have probably contested its last election and the new party would have been officially founded only after that election.", "In an atmosphere of reconciliation with Gianfranco Fini, Berlusconi also stated that the new party could see the participation of other parties.", "Finally, on 8 February, Berlusconi and Fini agreed to form a joint list under the PdL banner, allied with Lega Nord (LN).", "After the victory of the PdL in the 2008 Italian general election, AN was merged into the PdL in early 2009." ], [ "Ideology", "National Alliance's political programme emphasised:*traditional values, being often close to the position of the Catholic Church, despite some social liberal and secular attitudes;*law and order, especially laws aimed at controlling immigration and implementing punishment;*support for Israel, the United States and European integration;*prohibition of all drugs, including marijuana.Distinguishing itself from the MSI, the party distanced itself from Benito Mussolini and fascism, and made efforts to improve relations with Jewish groups.", "For example, after far-right skinheads celebrated the then-AN politician Gianni Alemanno's election as Mayor of Rome in 2008 by making the Roman salute outside the Palazzo Senatorio, Alemanno visited Rome Synagogue, where he gave a speech praising what he called the universal values of the fight against Nazism.", "The shift was also present in the rhetoric of the party's leader Fini, who went from declaring himself as \"fascist for the 2000s\" in 1987 when at the head of the MSI, to describing himself as a conservative at the time of the AN's launch in 1994.With most hardliners leaving the party, it sought to present itself as a respectable conservative party and to join forces with Forza Italia in the European People's Party and eventually in a united party of the centre-right.", "Historian David Broder has compared the AN to the People's Party in Spain, a post-Francisco Franco party.Although the party approved the market economy and held favourable views on liberalisation and the privatisation of state-owned companies, AN was to the left of Forza Italia on economic issues and sometimes supported statist policies.", "That is why the party was strong in Rome and Lazio, where most civil servants live.", "The implosion of the Christian Democrats created space for a more economically interventionist party of the conservative right, and the AN sought closer ties to the former DC factions that joined the Berlusconi-led alliances of the right.", "As part of this, it also moderated its stances on the European Union and immigration, both of which were conditionally accepted by the party's leadership.", "Moreover, AN presented itself as a party promoting national cohesion, national identity, and patriotism.Regarding institutional reforms, the party was a long-time supporter of presidentialism and a plurality voting system, and came to support also federalism and to fully accept the alliance with Lega Nord, although the relations with that party were tense at times, especially about issues regarding national unity.Fini, a moderniser who saw Nicolas Sarkozy and David Cameron as role-models, impressed an ambitious political line to the party, combining the pillars of conservative ideology like security, family values, and patriotism with a more progressive approach in other areas, such as stem cell research and supporting voting rights for legal aliens.", "Some of these positions were not shared by many members of the party, most of whom staunchly opposed stem cell research and artificial insemination." ], [ "Factions", "National Alliance was a heterogeneous political party and within it members were divided in different factions, some of them very organised:*Protagonist Right (''Destra Protagonista''), headed by Maurizio Gasparri and Ignazio La Russa, was the bigger faction and the closest to Forza Italia due to its liberal-conservative stances.", "*New Alliance (''Nuova Alleanza''), formerly called Right and Freedom (''Destra e Libertà''), headed by Altero Matteoli and Adolfo Urso, was formed by the staunchest supporters of Gianfranco Fini within the party and supported a liberal political agenda.", "*Social Right (''Destra Sociale''), led by Gianni Alemanno, advocated a more social approach to economic policy and was considered at the right of the party.", "It had close ties with the General Labour Union.", "*''D-Destra'', led by Francesco Storace, was the most conservative component of the party, proud of the MSI's tradition and in open opposition to Fini.", "Formed as a split from the Social Right, the group finally left AN and launched The Right in July 2007.", "*Christian Reformists (''Cristiano Riformisti'') was a minor Christian-democratic faction.In the party there was also a group named Ethic-Religious Council, whose board members included Gaetano Rebecchini (founder, ex-DC), Riccardo Pedrizzi (president), Franco Tofoni (vice-president), Luigi Gagliardi (secretary-general), Alfredo Mantovano, Antonio Mazzocchi, and Riccardo Migliori.", "This was not a faction but an official organism within the party and expressed the official position of the party on ethical and religious matters.", "Sometimes the group criticised Fini for his liberal views on abortion, artificial insemination, and stem-cell research, which led some notable ex-DC members as Publio Fiori to leave the party.", "Some members of the council, such as Pedrizzi and Mantovano, were described as members of an unofficial Catholic Right faction." ], [ "Popular support", "The party had roughly 10–15% support across Italy, having its strongholds in Central Italy, as well as Southern Italy

Sicily (10.9%), while competing in the North-East (Friuli-Venezia Giulia 15.5% and Veneto 11.3%).The party had a good showing in the first general election in which it took part, achieving 13.5% of

[ [ "Amygdalin" ], [ "Introduction", "'''Amygdalin''' (from Ancient Greek: '''' 'almond') is a naturally occurring chemical compound found in many plants, most notably in the seeds (kernels) of apricots, bitter almonds, apples, peaches, cherries and plums, and in the roots of manioc.Amygdalin is classified as a cyanogenic glycoside, because each amygdalin molecule includes a nitrile group, which can be released as the toxic cyanide anion by the action of a beta-glucosidase.", "Eating amygdalin will cause it to release cyanide in the human body, and may lead to cyanide poisoning.Since the early 1950s, both amygdalin and a chemical derivative named '''''laetrile''''' have been promoted as alternative cancer treatments, often under the misnomer '''vitamin B17''' (neither amygdalin nor laetrile is a vitamin).", "Scientific study has found them to not only be clinically ineffective in treating cancer, but also potentially toxic or lethal when taken by mouth due to cyanide poisoning.", "The promotion of laetrile to treat cancer has been described in the medical literature as a canonical example of quackery, and as \"the slickest, most sophisticated, and certainly the most remunerative cancer quack promotion in medical history\"." ], [ "Chemistry", "Amygdalin is a cyanogenic glycoside derived from the aromatic amino acid phenylalanine.", "Amygdalin and prunasin are common among plants of the family Rosaceae, particularly the genus ''Prunus'', Poaceae (grasses), Fabaceae (legumes), and in other food plants, including flaxseed and manioc.", "Within these plants, amygdalin and the enzymes necessary to hydrolyze it are stored in separate locations, and only mix as a result of tissue damage.", "This provides a natural defense system.Amygdalin is contained in stone fruit kernels, such as almonds, apricot (14 g/kg), peach (6.8 g/kg), and plum (4–17.5 g/kg depending on variety), and also in the seeds of the apple (3 g/kg).", "Benzaldehyde released from amygdalin provides a bitter flavor.", "Because of a difference in a recessive gene called ''Sweet kernal Sk'', much less amygdalin is present in nonbitter (or sweet) almond than bitter almond.", "In one study, bitter almond amygdalin concentrations ranged from 33 to 54 g/kg depending on variety; semibitter varieties averaged 1 g/kg and sweet varieties averaged 0.063 g/kg with significant variability based on variety and growing region.For one method of isolating amygdalin, the stones are removed from the fruit and cracked to obtain the kernels, which are dried in the sun or in ovens.", "The kernels are boiled in ethanol; on evaporation of the solution and the addition of diethyl ether, amygdalin is precipitated as minute white crystals.", "Natural amygdalin has the (''R'')-configuration at the chiral phenyl center.", "Under mild basic conditions, this stereogenic center isomerizes; the (''S'')-epimer is called '''neoamygdalin'''.", "Although the synthesized version of amygdalin is the (''R'')-epimer, the stereogenic center attached to the nitrile and phenyl groups easily epimerizes if the manufacturer does not store the compound correctly.Amygdalin is hydrolyzed by intestinal β-glucosidase (emulsin) and amygdalin beta-glucosidase (amygdalase) to give gentiobiose and L-mandelonitrile.", "Gentiobiose is further hydrolyzed to give glucose, whereas mandelonitrile (the cyanohydrin of benzaldehyde) decomposes to give benzaldehyde and hydrogen cyanide.", "Hydrogen cyanide in sufficient quantities (allowable daily intake: ~0.6 mg) causes cyanide poisoning which has a fatal oral dose range of 0.6–1.5 mg/kg of body weight." ], [ "Laetrile", "Laetrile (patented 1961) is a simpler semisynthetic derivative of amygdalin.", "Laetrile is synthesized from amygdalin by hydrolysis.", "The usual preferred commercial source is from apricot kernels (''Prunus armeniaca'').", "The name is derived from the separate words \"laevorotatory\" and \"mandelonitrile\".", "Laevorotatory describes the stereochemistry of the molecule, while mandelonitrile refers to the portion of the molecule from which cyanide is released by decomposition.A 500 mg laetrile tablet may contain between 2.5 and 25 mg of hydrogen cyanide.Like amygdalin, laetrile is hydrolyzed in the duodenum (alkaline) and in the intestine (enzymatically) to D-glucuronic acid and L-mandelonitrile; the latter hydrolyzes to benzaldehyde and hydrogen cyanide, that in sufficient quantities causes cyanide poisoning.Claims for laetrile were based on three different hypotheses: The first hypothesis proposed that cancerous cells contained copious beta-glucosidases, which release HCN from laetrile via hydrolysis.", "Normal cells were reportedly unaffected, because they contained low concentrations of beta-glucosidases and high concentrations of rhodanese, which converts HCN to the less toxic thiocyanate.", "Later, however, it was shown that both cancerous and normal cells contain only trace amounts of beta-glucosidases and similar amounts of rhodanese.The second proposed that, after ingestion, amygdalin was hydrolyzed to mandelonitrile, transported intact to the liver and converted to a beta-glucuronide complex, which was then carried to the cancerous cells, hydrolyzed by beta-glucuronidases to release mandelonitrile and then HCN.", "Mandelonitrile, however, dissociates to benzaldehyde and hydrogen cyanide, and cannot be stabilized by glycosylation.Finally, the third asserted that laetrile is the discovered vitamin B-17, and further suggests that cancer is a result of \"B-17 deficiency\".", "It postulated that regular dietary administration of this form of laetrile would, therefore, actually prevent all incidences of cancer.", "There is no evidence supporting this conjecture in the form of a physiologic process, nutritional requirement, or identification of any deficiency syndrome.", "The term \"vitamin B-17\" is not recognized by Committee on Nomenclature of the American Institute of Nutrition Vitamins.", "Ernst T. Krebs (not to be confused with Hans Adolf Krebs, the discoverer of the citric acid cycle) branded laetrile as a vitamin in order to have it classified as a nutritional supplement rather than as a pharmaceutical.=== History of laetrile ======= Early usage ====Amygdalin was first isolated in 1830 from bitter almond seeds (''Prunus dulcis'') by Pierre-Jean Robiquet and Antoine Boutron-Charlard.", "Liebig and Wöhler found three hydrolysis products of amygdalin: sugar, benzaldehyde, and prussic acid (hydrogen cyanide, HCN).", "Later research showed that sulfuric acid hydrolyzes it into D-glucose, benzaldehyde, and prussic acid; while hydrochloric acid gives mandelic acid, D-glucose, and ammonia.In 1845 amygdalin was used as a cancer treatment in Russia, and in the 1920s in the United States, but it was considered too poisonous.", "In the 1950s, a purportedly non-toxic, synthetic form was patented for use as a meat preservative, and later marketed as laetrile for cancer treatment.The U.S. Food and Drug Administration prohibited the interstate shipment of amygdalin and laetrile in 1977.Thereafter, 27 U.S. states legalized the use of amygdalin within those states.==== Subsequent results ====In a 1977 controlled, blinded trial, laetrile showed no more activity than placebo.Subsequently, laetrile was tested on 14 tumor systems without evidence of effectiveness.", "The Memorial Sloan–Kettering Cancer Center (MSKCC) concluded that \"laetrile showed no beneficial effects.\"", "Mistakes in an earlier MSKCC press release were highlighted by a group of laetrile proponents led by Ralph Moss, former public affairs official of MSKCC who had been fired following his appearance at a press conference accusing the hospital of covering up the benefits of laetrile.", "These mistakes were considered scientifically inconsequential, but Nicholas Wade in ''Science'' stated that \"even the appearance of a departure from strict objectivity is unfortunate.\"", "The results from these studies were published all together.A 2015 systematic review from the Cochrane Collaboration found: The authors also recommended, on ethical and scientific grounds, that no further clinical research into laetrile or amygdalin be conducted.Given the lack of evidence, laetrile has not been approved by the U.S. Food and Drug Administration or the European Commission.The U.S. National Institutes of Health evaluated the evidence separately and concluded that clinical trials of amygdalin showed little or no effect against cancer.", "For example, a 1982 trial by the Mayo Clinic of 175 patients found that tumor size had increased in all but one patient.", "The authors reported that \"the hazards of amygdalin therapy were evidenced in several patients by symptoms of cyanide toxicity or by blood cyanide levels approaching the lethal range.", "\"The study concluded \"Patients exposed to this agent should be instructed about the danger of cyanide poisoning, and their blood cyanide levels should be carefully monitored.", "Amygdalin (Laetrile) is a toxic drug that is not effective as a cancer treatment\".Additionally, \"No controlled clinical trials (trials that compare groups of patients who receive the new treatment to groups who do not) of laetrile have been reported.", "\"The side effects of laetrile treatment are the symptoms of cyanide poisoning.", "These symptoms include: nausea and vomiting, headache, dizziness, cherry red skin color, liver damage, abnormally low blood pressure, droopy upper eyelid, trouble walking due to damaged nerves, fever, mental confusion, coma, and death.The European Food Safety Agency's Panel on Contaminants in the Food Chain has studied the potential toxicity of the amygdalin in apricot kernels.", "The Panel reported, \"If consumers follow the recommendations of websites that promote consumption of apricot kernels, their exposure to cyanide will greatly exceed\" the dose expected to be toxic.", "The Panel also reported that acute cyanide toxicity had occurred in adults who had consumed 20 or more kernels and that in children \"five or more kernels appear to be toxic\".=== Advocacy and legality of laetrile ===Advocates for laetrile assert that there is a conspiracy between the US Food and Drug Administration, the pharmaceutical industry and the medical community, including the American Medical Association and the American Cancer Society, to exploit the American people, and especially cancer patients.Advocates of the use of laetrile have also changed the rationale for its use, first as a treatment of cancer, then as a vitamin, then as part of a \"holistic\" nutritional regimen, or as treatment for cancer pain, among others, none of which have any significant evidence supporting its use.Despite the lack of evidence for its use, laetrile developed a significant following due to its wide promotion as a \"pain-free\" treatment of cancer as an alternative to surgery and chemotherapy that have significant side effects.", "The use of laetrile led to a number of deaths.The FDA and AMA crackdown, begun in the 1970s, effectively escalated prices on the black market, played into the conspiracy narrative and enabled unscrupulous profiteers to foster multimillion-dollar smuggling empires.Some American cancer patients have traveled to Mexico for treatment with the substance, for example at the Oasis of Hope Hospital in Tijuana.", "The actor Steve McQueen died in Mexico following surgery to remove a stomach tumor, having previously undergone extended treatment for pleural mesothelioma (a cancer associated with asbestos exposure) under the care of William D. Kelley, a de-licensed dentist and orthodontist who claimed to have devised a cancer treatment involving pancreatic enzymes, 50 daily vitamins and minerals, frequent body shampoos, enemas, and a specific diet as well as laetrile.Laetrile advocates in the United States include Dean Burk, a former chief chemist of the National Cancer Institute cytochemistry laboratory, and national arm wrestling champion Jason Vale, who falsely claimed that his kidney and pancreatic cancers were cured by eating apricot seeds.", "Vale was convicted in 2004 for, among other things, fraudulently marketing laetrile as a cancer cure.", "The court also found that Vale had made at least $500,000 from his fraudulent sales of laetrile.In the 1970s, court cases in several states challenged the FDA's authority to restrict access to what they claimed are potentially lifesaving drugs.", "More than twenty states passed laws making the use of laetrile legal.", "After the unanimous Supreme Court ruling in ''United States v. Rutherford'' which established that interstate transport of the compound was illegal, usage fell off dramatically.", "The US Food and Drug Administration continues to seek jail sentences for vendors marketing laetrile for cancer treatment, calling it a \"highly toxic product that has not shown any effect on treating cancer.", "\"===In popular culture===The ''Law & Order'' episode \"Second Opinion\" is about a nutritional counselor named \"Doctor\" Haas giving patients laetrile as a cancer treatment for breast cancer as an alternative to getting a mastectomy." ], [ "See also", "* List of ineffective cancer treatments* Alternative cancer treatments" ], [ "References" ], [ "External links", "* Laetrile/Amygdalin information from the National Cancer Institute (U.S.A.)* Food and Drug Administration Commissioner's Decision on Laetrile* The Rise and Fall of Laetrile" ] ]

after-effects with no ill will towards the assailant.Although commonly used in a colloquial and less violent sense, the phrase is particularly associated with a specific sociopathic culture-bound syndrome in the cultures of Malaysia, Indonesia and Brunei.", "In a typical case of ''running amok'', an individual (almost always male), having shown no previous sign of anger or any inclination to violence, will acquire a weapon (traditionally a sword or dagger, but possibly any of a variety of weapons) and in a sudden frenzy, will attempt to kill or seriously injure anyone he encounters and himself.", "Amok typically takes place in a well-populated or crowded area.", "Amok episodes of this kind normally end with the attacker being killed by bystanders or committing suicide, eliciting theories that amok may be a form of intentional suicide in cultures where suicide is heavily stigmatized.", "Those who do not commit suicide and are not killed typically lose consciousness, and upon regaining consciousness, claim amnesia.An early Western description of the practice appears in the journals of British explorer Captain James Cook, who encountered amok firsthand in 1770 during a voyage around the world.", "Cook writes of individuals behaving in a reckless, violent manner, without cause and \"indiscriminately killing and maiming villagers and animals in a frenzied attack.", "\"A widely accepted explanation links amok with male honour (amok by women and children is virtually unknown).Running amok would thus be both a way of escaping the world (since perpetrators were normally killed or committed suicide) and re-establishing one's reputation as a man to be feared and respected." ], [ "Contemporary psychiatric syndrome", "In 1849, Amok was officially classified as a psychiatric condition based on numerous reports and case studies that showed the majority of individuals who committed amok were, in some sense, mentally ill. \"Running amok,\" is used to refer to the

anyone could experience an episode of Amok.", "Throughout history, mass murders have occurred in the United States, such as the Columbine High School massacre and the Sandy Hook Elementary School shooting, bringing into question if Amok syndrome is based on mental illness or the simple act of committing mass murder.", "Amok syndrome would, in turn, be more prevalent in other societies and not

''Symbolum Apostolorum'' or ''Symbolum Apostolicum''), sometimes titled the '''Apostolic Creed''' or the '''Symbol of the Apostles''', is a Christian creed or \"symbol of faith\".The creed most likely originated in 5th-century Gaul as a development of the Old Roman Symbol: the old Latin creed of the 4th century.", "It has been used in the Latin liturgical rites since the 8th century and, by extension, in the various modern branches of Western Christianity, including the modern liturgy and catechesis of the Catholic Church, Lutheranism, Anglicanism, Presbyterianism, Moravianism, Methodism, and Congregational churches.", "It is shorter than the full Niceno-Constantinopolitan Creed adopted in 381, but it is still explicitly trinitarian in structure, with sections affirming belief in God the Father, God the Son, and God the Holy Spirit.", "It does not address some Christological issues defined in the Nicene Creed.", "It thus says nothing explicitly about the divinity of either Jesus or the Holy Spirit.", "For this reason, it was held to predate the Nicene Creed in medieval Latin tradition.The expression \"Apostles' Creed\" is first mentioned in a letter from the Synod of Milan dated AD 390, referring to a belief at the time that each of the Twelve Apostles contributed an article to the twelve articles of the creed." ], [ "History", "The ecclesiastical use of Latin ''symbolum'' for \"creed\"—in the sense of \"a distinctive mark of Christians\", from the sense of Greek σύμβολον, \"a sign or token used for identification\"—first occurs around the middle of the 3rd century, in the correspondence of St. Cyprian and St. Firmilian, the latter in particular speaking of the trinitarian formula as the \"Symbol of the Trinity\", and recognizing it as an integral part of the rite of baptism.The term ''Symbolum Apostolicum'' appears for the first time in a letter, probably written by Ambrose, from a Council in Milan to Pope Siricius in about AD 390 \"Let them give credit to the Symbol of the Apostles, which the Roman Church has always kept and preserved undefiled\".", "Ambrose's term is here referring to the Old Roman Creed, the immediate predecessor of what is now known as the Apostles' Creed.", "The narrative of this creed having been jointly created by the Apostles, with each of the twelve contributing one of twelve articles, was already current at that time.This illumination from a 13th-century manuscript shows the apostles writing the Creed, receiving inspiration from the Holy Spirit.The Old Roman Creed had evolved from simpler texts based on Matthew 28:19, part of the Great Commission, and it has been argued that this earlier text was already in written form by the late 2nd century (c. 180).The earliest known formula is found within ''Testamentum in Galilaca Dominus.", "Noster.", "Iesu.", "Christi'' written between 150 and 180.This formula states: \"I believe in the Father almighty, - and in Jesus Christ, our Savior; - and in the Holy Spirit, the Paraclete, in the holy Church, and in the remission of sins.\"", "As can be seen, it lacks the Christological part of the Old Roman Creed.While the individual statements of belief that are included in the Apostles' Creed – even those not found in the Old Roman Symbol – are found in various writings by Irenaeus, Tertullian, Novatian, Marcellus, Rufinus, Ambrose, Augustine, Nicetas, and Eusebius Gallus, the earliest appearance of what we know as the Apostles' Creed was in the ''De singulis libris canonicis scarapsus'' (''Excerpt from Individual Canonical Books'') of St. Pirminius (Migne, ''Patrologia Latina'' 89, 1029 ff.", "), written between 710 and 714.Bettenson and Maunder state that it is first from ''Dicta Abbatis Pirminii de singulis libris canonicis scarapsus'' (''idem quod excarpsus'', excerpt), c. 750.The text of what is now known as the Apostles' Creed was most likely developed in southern Gaul around the midpoint of the 5th century.", "A creed that is virtually identical to the current one is recorded by Faustus of Riez.", "It is possible that Faustus had the identical text, as the original text written by Faustus cannot be reconstructed with certainty.", "A version that is identical to the current one with the single exception of ''infera'' in place of ''inferos'' is recorded in the late 5th century.", "However, the Old Roman Creed remained the standard liturgical text of the Roman Church throughout the 4th to 7th centuries.", "It was replaced by the \"Gallic\" version of the Apostles' Creed only in the later 8th century, under Charlemagne, who imposed it throughout his dominions.The phrase (\"he descended into hell\") is not found in the Nicene Creed.", "It echoes Ephesians 4:9, \"κατέβη εἰς τὰ κατώτερα μέρη τῆς γῆς\" (\"he descended into the lower earthly regions\").", "This phrase first appeared in one of the two versions of Rufinus (d. 411), the Creed of Aquileia, and then did not appear again in any version of the creed until AD 650.Similarly, the references to the communion of saints is found neither in the Old Roman Symbol nor in the Nicene Creed.The reference to God as \"creator of heaven and earth\" likewise is not in the Nicene Creed of 325, but it is present in the extended version of the Nicene Creed (the Niceno-Constantinopolitan Creed) of 381.The Eastern Orthodox Church does not use the Apostles' Creed, not because of an objection to any of its articles, but because of its omissions necessary for the definition of Nicene Christianity.", "The Orthodox delegates at the Council of Florence (1431–1449) explicitly challenged the western tradition that attributed the Apostles' Creed to the Twelve Apostles.", "This tradition was also shown to be historically untenable by Lorenzo Valla.", "The Roman Church does not state that text dates back to the Apostles themselves, the Roman catechism instead explaining that \"the Apostles' Creed is so called because it is rightly considered to be a faithful summary of the apostles' faith.\"" ], [ "Text", "The following gives the original Latin text, with the traditional division into twelve articles, alongside an English translation.", "Underlined passages are those not present in the Old Roman Symbol as recorded by Tyrannius Rufinus.1.Credo in Deum Patrem omnipotentem, Creatorem caeli et terrae, I believe in God the

the ''Psalterium Græcum et Romanum'', erroneously ascribed to Pope Gregory the Great.", "It was first edited by Archbishop Ussher in 1647, based on a manuscript preserved in the library of Corpus Christi College, Cambridge.The Latin text agrees with the \"Creed of Pirminius\" edited by Charles Abel Heurtley (''De Fide Symbolo'', 1900, p. 71).", "Four other Greek translations with slight variations were discovered by Carl Paul Caspari, and published in 1879 (''Alte und neue Quellen zur Geschichte des Taufsymbols'', vol.", "3, pp.", "11 sqq.", ").The tradition of assigning each article to one of the apostles specifically can be traced to the 6th century.", "In Western sacral art, ''Credo Apostolorum'' refers to the figurative representation of the twelve apostles each alongside one of the articles.", "This artistic tradition extends from the high medieval to the Baroque period.The precise division of the text and the sequence of attribution to the apostles has never been entirely fixed.", "For example, Pelbartus Ladislaus of Temesvár, writing in the late 15th century, divides article 5 in two but combines articles 11 and 12 into one, with the following attributions:" ], [ "Liturgical use in Western Christianity", "The Apostles' Creed is used in its direct form or in interrogative forms by Western Christian communities in several of their liturgical rites, in particular those of baptism and the Eucharist.=== Rite of baptism ===The Apostles' Creed, whose present form is similar to the baptismal creed used in Rome in the third and fourth centuries, actually developed from questions addressed to those seeking baptism.", "The Catholic Church still today uses an interrogative form of it in the Rite of Baptism (for both children and adults).", "In the official English translation (ICEL, 1974) the minister of baptism asks:To each question, the catechumen, or, in the case of an infant, the parents and sponsor(s) (godparent(s)) in his or her place, answers \"I do.\"", "Then the celebrant says:And all respond: Amen.The Presbyterian Church of Aotearoa New Zealand uses the Apostles' Creed in its baptism rite in spite of the reservations of some of its members regarding the phrase \"born of the virgin Mary\".The Episcopal Church in the United States of America uses the Apostles' Creed as part of a Baptismal Covenant for those who are to receive the Rite of Baptism.", "The Apostles' Creed is recited by candidates, sponsors and congregation, each section of the Creed being an answer to the celebrant's question, \"Do you believe in God the Father (God the Son, God the Holy Spirit)?\"", "It is also used in an interrogative form at the Easter Vigil in The Renewal of Baptismal Vows.The Church of England likewise asks the candidates, sponsors and congregation to recite the Apostles' Creed in answer to similar interrogations, in which it avoids using the word \"God\" of the Son and the Holy Spirit, asking instead: \"Do you believe and trust in his Son Jesus Christ?", "\", and \"Do you believe and trust in the Holy Spirit?\"", "Moreover, \"where there are strong pastoral reasons\", it allows use of an alternative formula in which the interrogations, while speaking of \"God the Son\" and \"God the Holy Spirit\", are more elaborate but are not based on the Apostles' Creed, and the response in each case is: \"I believe and trust in him.\"", "The ''Book of Common Prayer'' may also be used, which in its rite of baptism has the minister recite the Apostles' Creed in interrogative form.", "Asking the godparents or, in the case \"of such as are of Riper Years\", the candidate: \"Dost thou believe in God the Father ...\" The response is: \"All this I stedfastly believe.", "\"Lutherans following the ''Lutheran Service Book'' (Lutheran Church–Missouri Synod and the Lutheran Church–Canada), like Catholics and Anglicans, use the Apostles' Creed during the Sacrament of Baptism:Following each question, the candidate answers: \"Yes, I believe\".", "If the candidates are unable to answer for themselves, the sponsors are to answer the questions.For ELCA (Evangelical Lutheran Church in America) Lutherans who use the Evangelical Lutheran Worship book, the Apostles' Creed appears during the Sacrament of Holy Baptism Rite on p. 229 of the hardcover pew edition.The United Methodist Church in the United States uses the Apostles' Creed as part of their baptismal rites in the form of an interrogatory addressed to the candidate(s) for baptism and the whole congregation as a way of professing the faith within the context of the Church's sacramental act.", "For infants, it is the professing of the faith by the parents, sponsors, and congregation on behalf of the candidate(s); for confirmands, it is the professing of the faith before and among the congregation.", "For the congregation, it is a reaffirmation of their professed faith.=== Eucharistic rite ===Since the 2002 edition, the Apostles' Creed is included in the Roman Missal as an alternative, with the indication, \"Instead of the Niceno-Constantinopolitan Creed, especially during Lent and Easter time, the baptismal Symbol of the Roman Church, known as the Apostles' Creed, may be used.\"", "Previously the Nicene Creed was the only profession of faith that the Missal gave for use at Mass, except in Masses for children; but in some countries use of the Apostles' Creed was already permitted.=== Canonical hours ===The Apostles' Creed is used in Anglican services of Matins and Evening Prayer (Evensong).", "It is invoked after the recitation or singing of the Canticles, and is the only part of the services in which the congregation traditionally turns to face the altar, if they are seated transversely in the quire.The Episcopal Church (United States) uses the Apostles' Creed in Morning Prayer and Evening Prayer.Before the 1955 simplification of the rubrics of the Roman Breviary by Pope Pius XII, the Apostles' Creed was recited at the beginning of matins and prime, at the end of compline, and in some ''preces'' (a series of versicles and responses preceded by, eleison (\"Lord, have mercy\") and the Our Father) of prime and compline on certain days during Advent and Lent." ], [ "Indulgence", "Recitation of the ''Apostles' Creed'' or the ''Nicene-Constantinopolitan Creed'' is required to obtain a partial

'''agar-agar''', is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from \"ogonori\" (''Gracilaria'') and \"tengusa\" (Gelidiaceae).", "As found in nature, agar is a mixture of two components, the linear polysaccharide agarose and a heterogeneous mixture of smaller molecules called agaropectin.", "It forms the supporting structure in the cell walls of certain species of algae and is released on boiling.", "These algae are known as agarophytes, belonging to the Rhodophyta (red algae) phylum.", "The processing of food-grade agar removes the agaropectin, and the commercial product is essentially pure agarose.Agar has been used as an ingredient in desserts throughout Asia and also as a solid substrate to contain culture media for microbiological work.", "Agar can be used as a laxative; an appetite suppressant; a vegan substitute for gelatin; a thickener for soups; in fruit preserves, ice cream, and other desserts; as a clarifying agent in brewing; and for sizing paper and fabrics." ], [ "Etymology", "The word ''agar'' comes from '''agar-agar''', the Malay name for red algae

'''agal-agal''' or '''Ceylon agar'''." ], [ "History", "Ogonori, the most common red algae used to make agarMacroalgae have been used widely as food by coastal cultures, especially in Southeast Asia.", "In the Philippines, ''Gracilaria'', known as ''gulaman'' (or ''gulaman dagat'') in Tagalog, have been harvested and used as food for centuries, eaten both fresh or sun-dried and turned into jellies.", "The earliest historical attestation is from the ''Vocabulario de la lengua tagala'' (1754) by the Jesuit priests Juan de Noceda and Pedro de Sanlucar, where ''golaman'' or ''gulaman'' was defined as ''\"una yerva, de que se haze conserva a modo de Halea, naze en la mar\"'' (\"an herb, from which a jam-like preserve is made, grows in the sea\"), with an additional entry for ''guinolaman'' to refer to food made with the jelly.", "Carrageenan, derived from gusô (''Eucheuma'' spp.", "), which also congeals into a gel-like texture is also used similarly among the Visayan peoples and have been recorded in the even earlier ''Diccionario De La Lengua Bisaya, Hiligueina y Haraia de la isla de Panay y Sugbu y para las demas islas'' (c.1637) of the Augustinian missionary Alonso de Méntrida .", "In the book, Méntrida describes gusô as being cooked until it melts, and then allowed to congeal into a sour dish.Jelly seaweeds were also favoured and foraged by Malay communities living on the coasts of the Riau Archipelago and Singapore in Southeast Asia for centuries.The application of agar as a food additive in Japan is alleged to have been discovered in 1658 by Mino Tarōzaemon (), an innkeeper in current Fushimi-ku, Kyoto who, according to legend, was said to have discarded surplus seaweed soup (Tokoroten) and noticed that it gelled later after a winter night's freezing.Agar was first subjected to chemical analysis in 1859 by the French chemist Anselme Payen, who had obtained agar from the marine algae ''Gelidium corneum''.Beginning in the late 19th century, agar began to be used as a solid medium for growing various microbes.", "Agar was first described for use in microbiology in 1882 by the German microbiologist Walther Hesse, an assistant working in Robert Koch's laboratory, on the suggestion of his wife Fanny Hesse.", "Agar quickly supplanted gelatin as the base of microbiological media, due to its higher melting temperature, allowing microbes to be grown at higher temperatures without the media liquefying.With its newfound use in microbiology, agar production quickly increased.", "This production centered on Japan, which produced most of the world's agar until World War II.", "However, with the outbreak of World War II, many nations were forced to establish domestic agar industries in order to continue microbiological research.", "Around the time of World War II, approximately 2,500 tons of agar were produced annually.", "By the mid-1970s, production worldwide had increased dramatically to approximately 10,000 tons

of repeating units of agarobiose, a disaccharide made up of D-galactose and 3,6-anhydro-L-galactopyranose.", "Agaropectin is a heterogeneous mixture of smaller molecules that occur in lesser amounts, and is made up of alternating units of D-galactose and L-galactose heavily modified with acidic side-groups, such as sulfate, glucuronate, and pyruvate." ], [ "Physical properties", "Agar exhibits hysteresis because when mixed with water, it solidifies and forms a gel at about , which is called the gel point, and melts at , which is the melting point.", "Hysteresis of agar occurs due to the difference between the gel point and melting point temperatures.", "This property lends a suitable balance between easy melting and good gel stability at relatively high temperatures.", "Since many scientific applications require incubation at temperatures close to human body temperature (37 °C), agar is more appropriate than other solidifying agents that melt at this temperature, such as gelatin." ], [ "Uses", "=== Culinary ===''Sago at gulaman'' in Filipino cuisine is made from agar (''gulaman''), pearl sago, and sugar syrup flavored with pandan|210x210pxAgar-agar is a natural

desserts and vegetable aspics or incorporated with other desserts such as a layer of jelly in a cake.Agar-agar is approximately 80% dietary fiber, so it can serve as an intestinal regulator.", "Its bulking quality has been behind fad diets in Asia, for example the ''kanten'' (the Japanese word for agar-agar) diet.", "Once ingested, ''kanten'' triples in size and absorbs water.", "This results in the consumers feeling fuller.==== Asian culinary ====One use of agar in Japanese cuisine (Wagashi) is ''anmitsu'', a dessert made of small cubes of agar jelly and served in a bowl with various fruits or other ingredients.", "It is also the main ingredient in ''mizu yōkan'', another popular Japanese food.", "In Philippine cuisine, it is used to make the jelly bars in the various gulaman refreshments like ''sago't gulaman'', ''samalamig'', or desserts such as ''buko pandan'', ''agar flan'', ''halo-halo'', ''fruit cocktail jelly'', and the black and red ''gulaman'' used in various fruit salads.", "In Vietnamese cuisine, jellies made of flavored layers of agar agar, called ''thạch'', are a popular dessert, and are often made in ornate molds for special occasions.", "In Indian

====''Crema de mangga'', a traditional Filipino fruitcake, is made with an agar layer on top to keep the fruit components in placeIt can be used as addition to or as a replacement for pectin in jams and marmalades, as a substitute to gelatin for its superior gelling properties, and as a strengthening ingredient in souffles and custards.", "Another use of agar-agar is in a Russian dish ''ptich'ye moloko'' (bird's milk), a rich jellified custard (or soft meringue) used as a cake filling or chocolate-glazed as individual sweets.Agar-agar may also be used as the gelling agent in gel

containing agar gel for bacterial cultureAn agar plate or Petri dish is used to provide a growth medium using a mix of agar and other nutrients in which microorganisms, including bacteria and fungi, can be cultured and observed under the microscope.", "Agar is indigestible for many organisms so that microbial growth does not affect the gel used and it remains stable.", "Agar is typically sold commercially as a powder that can be mixed with water and prepared similarly to gelatin before use as a growth medium.", "Nutrients are typically added to meet the nutritional needs of the microbes organism, the formulations of which may be \"undefined\" where the precise composition is unknown, or \"defined\" where the exact chemical composition is known.", "Agar is often dispensed using a sterile media dispenser.Different algae produce various types of agar.", "Each agar has unique properties that suit different purposes.", "Because of the agarose component, the agar solidifies.", "When heated, agarose has the potential to melt and then solidify.", "Because of this property, they are referred to as \"physical gels\".", "In contrast, polyacrylamide polymerization is an irreversible process, and the resulting products are known as chemical gels.There are a variety of different types of agar that support the growth of different microorganisms.", "A nutrient agar may be permissive, allowing for the cultivation of any non-fastidious microorganisms; a commonly-used nutrient agar for bacteria is the Luria Bertani (LB) agar which contains lysogeny broth, a nutrient-rich medium used for bacterial growth.", "Other fastidious organisms may require the addition of different biological fluids such as horse or sheep blood, serum, egg yolk, and so on.", "Agar plates can also be selective, and can be used to promote the growth of bacteria of interest while inhibiting others.", "A variety of chemicals may be added to create an environment favourable for specific types of bacteria or bacteria with certain properties, but not conducive for growth of others.", "For example, antibiotics may be added in cloning experiments whereby bacteria with antibiotic-resistant plasmid are selected.==== Motility assays ====As a gel, an agar or agarose medium is porous and therefore can be used to measure microorganism motility and mobility.", "The gel's porosity is directly related to the concentration of agarose in the medium, so various levels of effective viscosity (from the cell's \"point of view\") can be selected, depending on the experimental objectives.A common identification assay involves culturing a sample of the organism deep within a block of nutrient agar.", "Cells will attempt to grow within the gel structure.", "Motile species will be able to migrate, albeit slowly, throughout the gel, and infiltration rates can then be visualized, whereas non-motile species will show growth only along the now-empty path introduced by the invasive initial sample deposition.Another setup commonly used for measuring chemotaxis and chemokinesis utilizes the under-agarose cell migration assay, whereby a layer of agarose gel is placed between a cell population and a chemoattractant.", "As a concentration gradient develops from the diffusion of the chemoattractant into the gel, various cell populations requiring different stimulation levels to migrate can then be visualized over time using microphotography as they tunnel upward through the gel against gravity along the gradient.=== Plant biology ===''Physcomitrella patens'' plants growing axenically in vitro on agar plates.", "Petri dish has diameter.Research grade agar is used extensively in plant biology as it is optionally supplemented with a nutrient and/or

solution is suitable for growth media between normal growth temps.When using agar, within any growth medium, it is important to know that the solidification of the agar is pH-dependent.", "The optimal range for solidification is between 5.4 and 5.7.Usually, the application of potassium hydroxide is needed to increase the pH to this range.", "A general guideline is about 600 μl 0.1M KOH per 250 ml GM.", "This entire mixture can be sterilized using the liquid cycle of an autoclave.This medium nicely lends itself to the application of specific concentrations of phytohormones etc.", "to induce specific growth patterns in that one can easily prepare a solution containing the desired amount of hormone, add it to the known volume of GM, and autoclave to both sterilize and evaporate off any solvent that may have been used to dissolve the often-polar hormones.", "This hormone/GM solution can be spread across the surface of Petri dishes sown with germinated and/or etiolated seedlings.Experiments with the moss ''Physcomitrella patens'', however, have shown that choice of the gelling agent – agar or Gelrite – does influence phytohormone sensitivity of the plant cell

rain can have harmful effects on plants, aquatic animals, and infrastructure.", "Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life-forms.", "In ecosystems, persistent acid rain reduces tree bark durability, leaving flora more susceptible to environmental stressors such as drought, heat/cold and pest infestation.", "Acid rain is also capable of detrimenting soil composition by stripping it of nutrients such as calcium and magnesium which play a role in plant growth and maintaining healthy soil.", "In terms of human infrastructure, acid rain also causes paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health.Some governments, including those in Europe and North America, have made efforts since the 1970s to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere through air pollution regulations.", "These efforts have had positive results due to the widespread research on acid rain starting in the 1960s and the publicized information on its harmful effects.", "The main source of sulfur and nitrogen compounds that result in acid rain are anthropogenic, but nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions." ], [ "Definition", "\"Acid rain\" is a popular term

"The pH of the sample was measured to be 4.03 at Hubbard Brook.", "The Hubbard Brook Ecosystem Study followed up with a series of research studies that analyzed the environmental effects of acid rain.", "Acid rain that mixed with stream water at Hubbard Brook was neutralized by the alumina from soils.", "The result of this research indicated that the chemical reaction between acid rain and aluminium leads to an increasing rate of soil weathering.", "Experimental research was done to examine the effects of increased acidity in streams on ecological species.", "In 1980, a group of scientists modified the acidity of Norris Brook, New Hampshire, and observed the change in species' behaviors.", "There was a decrease in species diversity, an increase in community dominants, and a decrease in the food web complexity.In 1980, the US Congress passed an Acid Deposition Act.", "This Act established an 18-year assessment and research program under the direction of the National Acidic Precipitation Assessment Program (NAPAP).", "NAPAP enlarged a network of monitoring sites to determine how acidic the precipitation actually was, seeking to determine long-term trends, and

Reagan commissioned William Nierenberg to serve on the National Science Board.", "Nierenberg selected scientists including Gene Likens to serve on a panel to draft a report on acid rain.", "In 1983, the panel of scientists came up with a draft report, which concluded that acid rain is a real problem and solutions should be sought.", "White House Office of Science and Technology Policy reviewed the draft report and sent Fred Singer's suggestions of the report, which cast doubt on the cause of acid rain.", "The panelists revealed rejections against Singer's positions and submitted the report to Nierenberg in April.", "In May 1983, the House of Representatives voted against legislation that aimed to control sulfur emissions.", "There was a debate about whether Nierenberg delayed to release

control emissions of sulfur dioxide and nitrogen oxides.", "Both these emissions proved to cause a significant problem on U.S. citizens and their access to healthy clean air.", "Title IV called for a total reduction of about 10 million tons of SO2 emissions from power plants, close to a 50% reduction.", "It was implemented in two phases.", "Phase I began in 1995, and limited sulfur dioxide emissions from 110 of the largest power plants to a combined total of 8.7 million tons of sulfur dioxide.", "One power plant in New England (Merrimack) was in Phase I.", "Four other plants (Newington,

principal natural phenomena that contribute acid-producing gases to the atmosphere are emissions from volcanoes.", "Thus, for example, fumaroles from the Laguna Caliente crater of Poás Volcano create extremely high amounts of acid rain and fog, with acidity as high as a pH of 2, clearing an area of any vegetation and frequently causing irritation to the eyes and lungs of inhabitants in nearby settlements.", "Acid-producing gasses are also created by biological processes that occur on the land, in wetlands, and in the oceans.", "The major biological source of sulfur compounds is dimethyl sulfide.Nitric acid in rainwater is an important source of fixed nitrogen for plant life, and is also produced by electrical activity in the atmosphere such as lightning.Acidic deposits have been detected in glacial ice thousands of years old in remote parts of the globe.===Human activity===The coal-fired Gavin Power Plant in Cheshire, OhioThe principal cause of acid rain is sulfur and nitrogen compounds from human sources, such as electricity generation, animal agriculture, factories, and motor vehicles.", "These also include power plants, which use electric power generators that account for a quarter of nitrogen oxides and two-thirds of sulfur dioxide within the atmosphere.", "Industrial acid rain is a substantial problem in China and Russia and areas downwind from them.", "These areas all burn sulfur-containing coal to generate heat and electricity.The problem of acid rain has not only increased with population and industrial growth, but has become more widespread.", "The use of tall smokestacks to reduce local pollution has contributed to the spread of acid rain by releasing gases into regional atmospheric circulation; dispersal from these taller stacks causes pollutants to be carried farther, causing widespread ecological damage.", "Often deposition occurs a considerable distance downwind of the emissions, with mountainous regions tending to receive the greatest deposition (because of their higher rainfall).", "An example of this effect is the low pH of rain which falls in Scandinavia.", "Regarding low pH and pH imbalances in correlation to acid rain, low levels, or those under the pH value of 7, are considered acidic.", "Acid rain falls at a pH value of roughly 4, making it harmful to consume for humans.", "When these low pH levels fall in specific regions, they not only affect the environment but also human health.", "With acidic pH levels in humans comes hair loss, low urinary pH, severe mineral imbalances, constipation, and many cases of chronic disorders like Fibromyalgia and Basal Carcinoma." ], [ "Chemical process", "Combustion of fuels produces sulfur dioxide and nitric oxides.", "They are converted into sulfuric acid and nitric acid.===Gas phase chemistry===In the gas phase sulfur dioxide is oxidized by reaction with the hydroxyl radical via an intermolecular reaction::SO2 + OH· → HOSO2·which is followed by::HOSO2· + O2 → HO2· + SO3In the presence of water, sulfur trioxide (SO3) is converted rapidly to sulfuric acid::SO3 (g) + H2O (l) → H2SO4 (aq)Nitrogen dioxide reacts with OH to form nitric acid:This shows the process of the air pollution being released into the atmosphere and the areas that will be affected.", ":NO2 + OH· → HNO3===Chemistry in cloud droplets===When clouds are present, the loss rate of SO2 is faster than can be explained by gas phase chemistry alone.", "This is due to reactions in the liquid water droplets.", ";HydrolysisSulfur dioxide dissolves in water and then, like carbon dioxide, hydrolyses in a series of equilibrium reactions::SO2 (g) + H2O SO2·H2O:SO2·H2O H+ + HSO3−:HSO3− H+ + SO32−;OxidationThere are a large number of aqueous reactions that oxidize sulfur from S(IV) to S(VI), leading to the formation of sulfuric acid.", "The most important oxidation reactions are with ozone, hydrogen peroxide and oxygen (reactions with oxygen are catalyzed by iron and manganese in the cloud droplets)." ], [ "Acid deposition", "===Wet deposition===Wet deposition of acids occurs when any form of precipitation (rain, snow, and so on) removes acids from the atmosphere and delivers it to the Earth's surface.", "This can result from the deposition of acids produced in the raindrops (see aqueous phase chemistry above) or by the precipitation removing the acids either in clouds or below clouds.", "Wet removal of both gases and aerosols are both of importance for wet deposition.===Dry deposition===Acid deposition also occurs via dry deposition in the absence of precipitation.", "This can be responsible for as much as 20 to 60% of total acid deposition.", "This occurs when particles and gases stick to the ground, plants or other surfaces." ], [ "Adverse effects", "Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life-forms as well as causing damage to buildings and having impacts on human health.===Surface waters and aquatic animals===Not all fish, shellfish, or the insects that they eat can tolerate the same amount of acid; for example, frogs can tolerate water that is more acidic (i.e., has a lower pH) than trout.Both the lower pH and higher aluminium concentrations in surface water that occur as a result of acid rain can cause damage to fish and other aquatic animals.", "At pH lower than 5 most fish eggs will not hatch and lower pH can kill adult fish.", "As lakes and rivers become more acidic biodiversity is reduced.", "Acid rain has eliminated insect life and some fish species, including the brook trout in some lakes, streams, and creeks in geographically sensitive areas, such as the Adirondack Mountains of the United States.", "However, the extent to which acid rain contributes directly or indirectly via runoff from the catchment to lake and river acidity (i.e., depending on characteristics of the surrounding watershed) is variable.", "The United States Environmental Protection Agency's (EPA) website states: \"Of the lakes and streams surveyed, acid rain caused acidity in 75% of the acidic lakes and about 50% of the acidic streams\".", "Lakes hosted by silicate basement rocks are more acidic than lakes within limestone or other basement rocks with a carbonate composition (i.e.", "marble) due to buffering effects by carbonate minerals, even with the same amount of acid rain.Sulfur dioxide and nitrous oxide concentration has many implication on aquatic ecosystems, including acidity change, increased nitrogen and aluminum content, and altering biogeochemical processes.", "Typically, sulfur dioxide and nitrous oxide do not have direct physiological effects upon exposure; most effects are developed by accumulation and prolonged exposure of these gases in the environment, modifying soil and water chemistry.===Soils===Soil biology and chemistry can be seriously damaged by acid rain.", "Some microbes are unable to tolerate changes to low pH and are killed.", "The enzymes of these microbes are denatured (changed in shape so they no longer function) by the acid.", "The hydronium ions of acid rain also mobilize toxins, such as aluminium, and leach away essential nutrients and minerals such as magnesium.", ":2 H+ (aq) + Mg2+ (clay) 2 H+ (clay) + Mg2+ (aq)Soil chemistry can be dramatically changed when base cations, such as calcium and magnesium, are leached by acid rain, thereby affecting sensitive species, such as sugar maple (Acer saccharum).", "'''Soil acidification'''Diagram of nutrient leaching in soil with high levels of Soil acidity.Impacts of acidic water and soil acidification on plants could be minor or in most cases major.", "Most minor cases which do not result in fatality of plant life can be attributed to the plants being less susceptible to acidic conditions and/or the acid rain being less potent.", "However, even in minor cases, the plant will eventually die due to the acidic water lowering the plant's natural pH.", "Acidic water enters the plant and causes important plant minerals to dissolve and get carried away; which ultimately causes the plant to die of lack of minerals for nutrition.", "In major cases, which are more extreme, the same process of damage occurs as in minor cases, which is removal of essential minerals, but at a much quicker rate.", "Likewise, acid rain that falls on soil and on plant leaves causes drying of the waxy leaf cuticle, which ultimately causes rapid water loss from the plant to the outside atmosphere and eventually results in death of the plant.", "To see if a plant is being affected by soil acidification, one can closely observe the plant leaves.", "If the leaves are green and look healthy, the soil pH is normal and acceptable for plant life.", "But if the plant leaves have yellowing between the veins on their leaves, that means the plant is suffering from acidification and is unhealthy.", "Moreover, a plant suffering from soil acidification cannot photosynthesize; the acid-water-induced process of drying out of the plant can destroy chloroplast organelles.", "Without being able to photosynthesize, a plant cannot create nutrients for its own survival or oxygen for the survival of aerobic organisms, which affects most species on Earth and ultimately ends the purpose of the plant's existence.", "===Forests and other vegetation===Black Triangle in Europe.Adverse effects may be indirectly related to acid rain, like the acid's effects on soil (see above) or high concentration of gaseous precursors to acid rain.", "High altitude forests are especially vulnerable as they are often surrounded by clouds and fog which are more acidic than rain.Other plants can also be damaged by acid rain, but the effect on food crops is minimized by the application of lime and fertilizers to replace lost nutrients.", "In cultivated areas, limestone may also be added to increase the ability of the soil to keep the pH stable, but this tactic is largely unusable in the case of wilderness lands.", "When calcium is leached from the needles of red spruce, these trees become less cold tolerant and exhibit winter injury and even death.===Ocean acidification===Acid rain has a much less harmful effect on oceans on a global scale, but it creates an amplified impact in the shallower waters of coastal waters.", "Acid rain can cause the ocean's pH to fall, known as ocean acidification, making it more difficult for different coastal species to create their exoskeletons that they need to survive.", "These coastal species link together as part of the ocean's food chain, and without them being a source for other marine life to feed off of, more marine life will die.", "Coral's limestone skeleton is particularly sensitive to pH decreases, because the calcium carbonate, a core component of the limestone skeleton, dissolves in acidic (low pH) solutions.In addition to acidification, excess nitrogen inputs from the atmosphere promote increased growth of phytoplankton and other marine plants, which, in turn, may cause more frequent harmful algal blooms and eutrophication (the creation of oxygen-depleted \"dead zones\") in some parts of the ocean.===Human health effects===Acid rain does not directly affect human health.", "The acid in the rainwater is too dilute to have direct adverse effects.", "The particulates responsible for acid rain (sulfur dioxide and nitrogen oxides) do have an adverse effect.", "These particulates come together and react in the atmosphere, forming nitrate particles and fine sulfate.", "Exposure to high amounts of these particles, particularly over a long period of time, can cause irritation to the eyes and skin, increased fluid in the lungs, and dental damage and erosion.", "Increased amounts of fine particulate matter in the air contribute to heart and lung problems, including asthma and bronchitis.", "These particular effects on the heart and lungs can alter their function, including heart attack caused death for those with an increased risk of heart disease and other heart conditions.", "===Other adverse effects===rightrightAcid rain can damage buildings, historic monuments, and statues, especially those made of rocks, such as limestone and marble, that contain large amounts of calcium carbonate.", "Acids in the rain react with the calcium compounds in the stones to create gypsum, which then flakes off.", ":CaCO3 (s) + H2SO4 (aq) CaSO4 (s) + CO2 (g) + H2O (l)The effects of this are commonly seen on old gravestones, where acid rain can cause the inscriptions to become completely illegible.", "Acid rain also increases the corrosion rate of metals, in particular iron, steel, copper and bronze." ], [ "Affected areas", "Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern third of the United States, and southeastern Canada.", "Other affected areas include the southeastern coast of China and Taiwan." ], [ "Prevention methods", "===Technical solutions===Many coal-firing power stations use flue-gas desulfurization (FGD) to remove sulfur-containing gases from their stack gases.", "For a typical coal-fired power station, FGD will remove 95% or more of the SO2 in the flue gases.", "An example of FGD is the wet scrubber which is commonly used.", "A wet scrubber is basically a reaction tower equipped with a fan that extracts hot smoke stack gases from a power plant into the tower.", "Lime or limestone in slurry form is also injected into the tower to mix with the stack gases and combine with the sulfur dioxide present.", "The calcium carbonate of the limestone produces pH-neutral calcium sulfate that is physically removed from the scrubber.", "That is, the scrubber turns sulfur pollution into industrial sulfates.In some areas the sulfates are sold to chemical companies as gypsum when the purity of calcium sulfate is high.", "In others, they are placed in landfill.", "The effects of acid rain can last for generations, as the effects of pH level change can stimulate the continued leaching of undesirable chemicals into otherwise pristine water sources, killing off vulnerable insect and fish species and blocking efforts to restore native life.Fluidized bed combustion also reduces the amount of sulfur emitted by power production.Vehicle emissions control reduces emissions of nitrogen oxides from motor vehicles.===International treaties===Governmental action to combat the effects of acid rainInternational treaties on the long-range transport of atmospheric pollutants have been agreed upon by western countries for some time now.", "Beginning in 1979, European countries convened in order to ratify general principles discussed during the UNECE Convention.", "The purpose was to combat Long-Range Transboundary Air Pollution.", "The 1985 Helsinki Protocol on the Reduction of Sulfur Emissions under the Convention on Long-Range Transboundary Air Pollution furthered the results of the convention.", "Results of the treaty have already come to fruition, as evidenced by an approximate 40 percent drop in particulate matter in North America.", "The effectiveness of the Convention in combatting acid rain has inspired further acts of international commitment to prevent the proliferation of particulate matter.", "Canada and the US signed the Air Quality Agreement in 1991.Most European countries and Canada signed the treaties.", "Activity of the Long-Range Transboundary Air Pollution Convention remained dormant after 1999, when 27 countries convened to further reduce the effects of acid rain.", "In 2000, foreign cooperation to prevent acid rain was sparked in Asia for the first time.", "Ten diplomats from countries ranging throughout the continent convened to discuss ways to prevent acid rain.", "Following these discussions, the Acid Deposition Monitoring Network in East Asia (EANET) was established in 2001 as an intergovernmental initiative to provide science-based inputs for decision makers and promote international cooperation on acid deposition in East Asia.", "In 2023, the EANET member countries include Cambodia, China, Indonesia, Japan, Lao PDR, Malaysia, Mongolia, Myanmar, the Philippines, Republic of Korea, Russia, Thailand and Vietnam.===Emissions trading===In this regulatory scheme, every current polluting facility is given or may purchase on an open market an emissions allowance for each unit of a designated pollutant it emits.", "Operators can then install pollution control equipment, and sell portions of their emissions allowances they no longer need for their own operations, thereby recovering some of the capital cost of their investment in such equipment.", "The intention is to give operators economic incentives to install pollution controls.The first emissions trading market was established in the United States by enactment of the Clean Air Act Amendments of 1990.The overall goal of the Acid Rain Program established by the Act is to achieve significant environmental and public health benefits through reductions in emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx), the primary causes of acid rain.", "To achieve this goal at the lowest cost to society, the program employs both regulatory and market based approaches for

song about 18 minutes in length that has since become a Thanksgiving anthem.", "His only top-40 hit was a cover of Steve Goodman's \"City of New Orleans\".", "His song \"Massachusetts\" was named the official folk song of the state, in which he has lived most of his adult life.", "Guthrie has also made several acting appearances.", "He is the father of four children, who have also had careers as musicians." ], [ "Early life", "Guthrie was born in the Coney Island neighborhood of Brooklyn, the son of the folk singer and composer Woody Guthrie and dancer Marjorie Mazia Guthrie.", "He is the fifth, and oldest surviving, of Woody Guthrie's eight children; two older half-sisters died of Huntington's disease (of which Woody also died in 1967), an older half-brother died in a train accident, another half sister died in a car accident, and a fourth sister died in childhood.", "His sister is the record producer Nora Guthrie.", "His mother was a professional dancer with the Martha Graham Company and founder of what is now the Huntington's Disease Society of America.", "Arlo's father was from a Baptist family of English and Scottish descent; and his mother was Jewish, the daughter of immigrants from Ukraine.", "His maternal grandmother was Yiddish poet Aliza Greenblatt, and country/western singer Jack Guthrie, who died when Arlo was an infant, was Arlo's cousin once removed.Guthrie received religious training for his bar mitzvah from Rabbi Meir Kahane, who formed the Jewish Defense League.", "\"Rabbi Kahane was a really nice, patient teacher,\" Guthrie later recalled, \"but shortly after he started giving me my lessons, he started going haywire.", "Maybe I was responsible.\"", "Guthrie converted to Catholicism in 1977, before embracing interfaith beliefs later in his life.", "\"I firmly believe that different religious traditions can reside in one person, or one nation or even one world,\" Guthrie said in 2015.In 2020, following his retirement, Guthrie expressed a philosophical affinity for gospel music, noting: \"Gospel music to me is the biggest genre of protest music.", "If this world ain't doing it for you, and your hopes are in the next one you can't get more protest than that.", "\"Guthrie attended Woodward School in Clinton Hill, Brooklyn, from first through eighth grades and later graduated from the Stockbridge School, in Stockbridge, Massachusetts, in 1965.He spent the summer of 1965 in London, eventually meeting Karl Dallas, who connected Guthrie with London's folk rock scene and became a lifelong friend of his.", "He briefly attended Rocky Mountain College, in Billings, Montana.", "He received an honorary doctorate from Siena College in 1981 and from Westfield State College in 2008.As a singer, songwriter and lifelong political activist, Guthrie carries on the legacy of his father.", "He was awarded the Peace Abbey Courage of Conscience award on September 26, 1992." ], [ "\"Alice's Restaurant\"", "Guthrie performing during his 2005 ''Alice's Restaurant Massacree 40th Anniversary'' tourOn November 26, 1965, while in Stockbridge, Massachusetts, during Thanksgiving break from his brief stint in college, 18-year-old Guthrie and his friend, Richard Robbins, were arrested for illegally dumping on private property what Guthrie described as \"a half-ton of garbage\" from the home of his friends, teachers Ray and Alice Brock, after he discovered that the local landfill was closed for the holiday.", "Guthrie and Robbins appeared in court, pled guilty to the charges, were levied a nominal fine and picked up the garbage that weekend.This littering charge served as the basis for Guthrie's most famous work, \"Alice's Restaurant Massacree\", a talking blues song that runs 18 minutes and 34 seconds in its original recorded version.", "In 1997, Guthrie jokingly pointed out that this was also the exact length of one of the infamous gaps in President Richard Nixon's Watergate tapes, and that Nixon owned a copy of the record.", "The Alice in the song is Alice Brock, who had been a librarian at Arlo's boarding school in the town before opening her restaurant.", "She later opened an art studio in Provincetown, Massachusetts.The song lampoons the Vietnam War draft.", "However, Guthrie has stated in multiple interviews that the song is more an \"anti-stupidity\" song than an anti-war song, adding that it is based on a true incident.", "In the song, Guthrie is called up for a draft examination and rejected as unfit for military service as a result of a criminal record consisting solely of one conviction for the aforementioned littering.", "Alice and her restaurant are the subjects of the refrain, but are generally mentioned only incidentally in the story (early drafts of the song explained that the restaurant was a place to hide from the police).", "Though her presence is implied at certain points in the story, Alice herself is described explicitly in the tale only briefly when she bails Guthrie and a friend out of jail.", "On the DVD commentary for the 1969 movie, Guthrie stated that the events presented in the song all actually happened (others, such as the arresting officer, William Obanhein, disputed some of the song's details, but generally verified the truth of the overall story).", "\"Alice's Restaurant\" was the song that earned Guthrie his first recording contract, after counterculture radio host Bob Fass began playing a tape recording of one of Guthrie's live performances of the song repeatedly one night in 1967.A performance at the Newport Folk Festival on July 17, 1967, was also very well received.", "Soon afterward, Guthrie recorded the song in front of a studio audience in New York City and released it as side one of the album, ''Alice's Restaurant''.", "By the end of the decade, Guthrie had gone from playing coffee houses and small venues to playing massive and prestigious venues such as Carnegie Hall and the Woodstock Festival.For a short period after its release in October 1967, \"Alice's Restaurant\" was heavily played on U.S. college and counterculture radio stations.", "It became a symbol of the late 1960s, and for many it defined an attitude and lifestyle that were lived out across the country in the ensuing years.", "Its leisurely finger-picking acoustic guitar and rambling lyrics were widely memorized and played by irreverent youth.", "Many stations in the United States have a Thanksgiving Day tradition of playing \"Alice's Restaurant\".A 1969 film, directed and co-written by Arthur Penn, was based on the true story told in the song, but with the addition of a large number of fictional scenes.", "This film, also called ''Alice's Restaurant'', featured Guthrie and several other figures in the song portraying themselves.", "The part of his father Woody Guthrie, who had died in 1967, was played by actor Joseph Boley; Alice, who made a cameo appearance as an extra, was also recast, with actress Pat Quinn in the title role.", "Guthrie, Brock and Robbins have all spoken out about their dissatisfaction with the film and the way they were portrayed.Despite its popularity, the song \"Alice's Restaurant Massacree\" was not always featured on the setlist of any given Guthrie performance.", "Since putting it back into his setlist in 1984, he has performed the song every ten years, stating in a 2014 interview that the Vietnam War had ended by the 1970s and that everyone who was attending his concerts had likely already heard the song anyway.", "So, after a brief period in the late 1960s and early 1970s when he replaced the monologue with a fictional one involving \"multicolored rainbow roaches\", he decided to do it only on special occasions from that point forward." ], [ "Musical career and critical reception", "Guthrie performing with the Guthrie Family Legacy Tour 2007The \"Alice's Restaurant\" song was one of a few very long songs to become popular just when albums began replacing hit singles as young people's main music listening.", "But in 1972 Guthrie had a highly successful single as well: Steve Goodman's song \"City of New Orleans\", a wistful paean to long-distance passenger rail travel.", "Guthrie's first trip on that train was in December 2005 (when his family joined other musicians on a train trip across the country to raise money for musicians financially devastated by Hurricane Katrina and Hurricane Rita, in the South of the United States).", "He also had a minor hit with his song \"Coming into Los Angeles\", which was played at the 1969 Woodstock Festival, but did not get much radio airplay because of its plot (involving the smuggling of drugs from London by airplane), and success with a live version of \"The Motorcycle Song\" (one of the songs on the B-side of the ''Alice's Restaurant'' album).", "A cover of the folk song \"Gypsy Davy\" was a hit on the easy listening charts.In the fall of 1975 during a benefit concert in Massachusetts, Guthrie performed with his band, Shenandoah, in public for the first time.", "They continued to tour and record throughout the 1970s until the early 1990s.", "Although the band received good reviews, it never gained the popularity that Guthrie did while playing solo.", "Shenandoah consisted of (after 1976) David Grover, Steve Ide, Carol Ide, Terry A La Berry and Dan Velika and is not to be confused with the country music group Shenandoah.", "The Ides, along with Terry a la Berry, reunited with Guthrie for a 2018 tour.", "Guthrie has performed a concert almost every Thanksgiving weekend since he became famous at Carnegie Hall, a tradition he announced would come to an end after the 2019 concert.Guthrie's 1976 album ''Amigo'' received a five-star (highest rating) from ''Rolling Stone'', and may be his best-received work.", "However, that album, like Guthrie's earlier Warner Bros. Records albums, is rarely heard today, even though each contains strong folk and folk rock music accompanied by widely regarded musicians such as Ry Cooder.A number of musicians from a variety of genres have joined Guthrie onstage, including Pete Seeger, David Bromberg, Cyril Neville, Emmylou Harris, Willie Nelson, Judy Collins, John Prine, Wesley Gray, Josh Ritter, and others.", "A video from a concert with Seeger at Wolf Trap in 1993 has been a staple of YouTube, with Guthrie's story-telling showcased in a performance of \"Can't Help Falling in Love\".", "In 2020, Guthrie collaborated with Jim Wilson on a cover of Stephen Foster's \"Hard Times Come Again No More\".On October 23, 2020, Guthrie announced via Facebook that he had \"reached the difficult decision that touring and stage shows are no longer possible,\" due to a series of strokes that had impaired his ability to walk and perform.", "All of his scheduled tour appearances for 2020 were cancelled, and Guthrie said he will not accept any new bookings offered.", "His final performance at Carnegie Hall was on November 29, 2019.His final live touring concert was on March 7, 2020, at The Caverns in Pelham, Tennessee.", "He had attempted to record some private concerts in the summer of 2020 but concluded his playing was no longer up to his standards.Guthrie rescinded his retirement announcement and stated that he would begin touring again in April 2023, albeit with his appearances reduced to locations in the Northeast within driving distance of his Massachusetts home, spaced at least one week apart to allow him to return home between shows.", "Due to the inhibitions caused by the stroke, the ''What's Left of Me'' tour will be mostly conversations with Bob Santelli and archival video \"with maybe some music included,\" but he embarked on the comeback tour in an effort to rehabilitate from his stroke more quickly.", "Guthrie expressed no interest in further tours after ''What's Left of Me'' ended, conceding he was no longer interested nor physically able to \"live in a tour bus.\"" ], [ "Acting", "Though Guthrie is best known for being a musician, singer, and composer, throughout the years he has also appeared as an actor in films and on television.", "The film ''Alice's Restaurant'' (1969) is his best known role, but he has had small parts in several films and even co-starred in a television drama, ''Byrds of Paradise''.Guthrie has had minor roles in several movies and television series.", "Usually, he has appeared as himself, often performing music and/or being interviewed about the 1960s, folk music and various social causes.", "His television appearances have included a broad range of programs from ''The Muppet Show'' (1979) to ''Politically Incorrect'' (1998).", "A rare dramatic film part was in the 1992 movie ''Roadside Prophets''.", "Guthrie's memorable appearance at the 1969 Woodstock Festival was documented in the Michael Wadleigh film ''Woodstock''.Guthrie also made a pilot for a TV variety show called ''The Arlo Guthrie Show'' in February 1987.The hour-long program included story telling and musical performances and was filmed in Austin, Texas.", "It was broadcast nationally on PBS.", "Special guests were Pete Seeger, Bonnie Raitt, David Bromberg and Jerry Jeff Walker." ], [ "Politics", "In his earlier years, at least from the 1960s to the 1980s, Guthrie had taken what seemed a left-leaning approach to American politics, influenced by his father.", "In his often lengthy comments during concerts, his expressed positions were consistently anti-war, anti-Nixon, pro-drugs and in favor of making nuclear power illegal.", "However, he apparently did not perceive himself as the major youth culture spokesperson he had been regarded as by the media, as evidenced by the lyrics in his 1979 song \"Prologue\": \"I can remember all of your smiles during the demonstrations ... and together we sang our victory songs though we were worlds apart.\"", "A 1969 rewrite of \"Alice's Restaurant\" pokes fun at former President Lyndon Johnson and his staff.In 1984, he was the featured celebrity in George McGovern's presidential campaign for the Democratic presidential nomination in Guthrie's home state of Massachusetts, performing at rallies and receptions.Guthrie identified as a registered Republican in 2008.He endorsed Texas Congressman Ron Paul for the 2008 Republican Party nomination, and said, \"I love this guy.", "Dr. Paul is the only candidate I know of who would have signed the Constitution of the United States had he been there.", "I'm with him, because he seems to be the only candidate who actually believes it has as much relevance today as it did a couple of hundred years ago.", "I look forward to the day when we can work out the differences we have with the same revolutionary vision and enthusiasm that is our American legacy.\"", "He told ''The New York Times Magazine'' that he (had become) a Republican because, \"We had enough good Democrats.", "We needed a few more good Republicans.", "We needed a loyal opposition.", "\"Commenting on the 2016 election, Guthrie identified himself as an independent, and said he was \"equally suspicious of Democrats as I am of Republicans\".", "He declined to endorse a candidate, noting that he personally liked Bernie Sanders despite disagreeing with parts of Sanders' platform.", "While he thought it \"wonderful\" that Donald Trump was not relying on campaign donations, he did not believe that it necessarily meant that Trump had the best interests of the country in mind.In 2018, Guthrie contacted publication ''Urban Milwaukee'' to clarify his political stance.", "He stated \"I am not a Republican\", and expressed deep disagreement with the Trump administration's views, especially its policies on immigration and treatment of detained immigrants by ICE.", "Guthrie further clarified, \"I left the party years ago and do not identify myself with either party these days.", "I strongly urge my fellow Americans to stop the current trend of guilt by association, and look beyond the party names and affiliations, and work for candidates whose policies are more closely aligned with their own, whatever they may be.", "...", "I don't pretend to be right all the time, and sometimes I've gone so far as to change my mind from time to time.", "\"Guthrie expressed support for the George Floyd protests in June 2020, stating that it would be good if politicians \"embraced it rather than resist the evolving nature of what it means to be an American\".In 2023, Guthrie stated that though he still maintained his personal convictions on particular issues, he had grown to become largely apolitical.", "He expressed irritation at having his past political views be brought up in later interviews and commented that the collapse of the groups and institutions that his parents' generation had embraced in favor of an overly individualist culture was \"disheartening\", but a natural progression of society." ], [ "Legacy", "Arlo Guthrie in 2010 in NurembergLike his father, Woody Guthrie, he often sings songs of protest against social injustice.", "He collaborated with poet Adrian Mitchell to tell the story of Chilean folk singer and activist Víctor Jara in song.", "He regularly performed with folk musician Pete Seeger, one of his father's longtime partners.", "Ramblin' Jack Elliott, who had lived for two years in the Guthries' home before Arlo left for boarding school, had absorbed Woody's style perhaps better than anyone; Arlo has been said to have credited Elliott for passing it along to him.In 1991, Guthrie bought the church that had served as Alice and Ray Brock's former home in Great Barrington, Massachusetts, and converted it to the Guthrie Center, an interfaith meeting place that serves people of all religions.", "The center provides weekly free lunches in the community and support for families living with HIV/AIDS, as well as other life-threatening illnesses.", "It also hosts a summertime concert series and Guthrie does six or seven fund raising shows there every year.", "There are several annual events such as the Walk-A-Thon to Cure Huntington's Disease and a \"Thanksgiving Dinner That Can't Be Beat\" for families, friends, doctors and scientists who live and work with Huntington's disease.One of the title characters in the comic strip ''Arlo and Janis'' is named after Guthrie.", "Cartoonist Jimmy Johnson noted he was inspired by a friend who resembled Guthrie to name one of his characters Arlo.", "English commentator Arlo White was named after Guthrie.Guthrie was the subject of a 2012 unauthorized biography, ''Arlo Guthrie: The Warner Reprise Years'', by Hank Reineke, for which Guthrie refused to cooperate.", "After finding Reineke's work to be \"better than (he) imagined it\" and feeling it had suffered from Guthrie's non-participation in it, he agreed to assist Reineke in the sequel, ''Rising Son: The Life and Music of Arlo Guthrie'', which is being released in 2023.Guthrie has expressed no interest in writing any memoir or tell-all." ], [ "Personal life",

shows, citing health issues, including a stroke on Thanksgiving Day 2019 which required brief hospitalization and physical therapy.", "On his official website and in social media, he posted, \"A folksinger's shelf life may be a lot longer than a dancer or an athlete, but at some point, unless you're incredibly fortunate or just plain whacko (either one or both) it's time to hang up the 'Gone Fishing' sign.", "Going from town to town and doing stage shows, remaining on the road is no longer an option.\"", "In a November 2023 interview, Guthrie conceded that he was having difficulty adjusting to retirement and not being able to perform the way he had his entire life.On October 23, 2021, Guthrie announced that he was engaged to Marti Ladd, with whom he had been in a relationship

can produce free radicals.", "Autoxidation leads to degradation of organic compounds, including living matter.", "Antioxidants are frequently added to industrial products, such as polymers, fuels, and lubricants, to extend their usable lifetimes.", "Foods are also treated with antioxidants to forestall spoilage, in particular the rancidification of oils and fats.", "In cells, antioxidants such as glutathione, mycothiol or bacillithiol, and enzyme systems like superoxide dismutase, can prevent damage from oxidative stress.Known dietary antioxidants are vitamins A, C, and E, but the term ''antioxidant'' has also been applied to numerous other dietary compounds that only have antioxidant properties in vitro, with little evidence for antioxidant properties in vivo.", "Dietary supplements marketed as antioxidants have not been shown to maintain health or prevent disease in humans." ], [ "History", "As part of their adaptation from marine life, terrestrial plants began producing non-marine antioxidants such as ascorbic acid (vitamin C), polyphenols and tocopherols.", "The evolution of angiosperm plants between 50 and 200 million years ago resulted in the development of many antioxidant pigments – particularly during the Jurassic period – as chemical defences against reactive oxygen species that are byproducts of photosynthesis.", "Originally, the term antioxidant specifically referred to a chemical that prevented the consumption of oxygen.", "In the late 19th and early 20th centuries, extensive study concentrated on the use of antioxidants in important industrial processes, such as the prevention of metal corrosion, the vulcanization of rubber, and the polymerization of fuels in the fouling of internal combustion engines.Early research on the role of antioxidants in biology focused on their use in preventing the oxidation of unsaturated fats, which is the cause of rancidity.", "Antioxidant activity could be measured simply by placing the fat in a closed container with oxygen and measuring the rate of oxygen consumption.", "However, it was the identification of vitamins C and E as antioxidants that revolutionized the field and led to the realization of the importance of antioxidants in the biochemistry of living organisms.", "The possible mechanisms of action of antioxidants were first explored when it was recognized that a substance with anti-oxidative activity is likely to be one that is itself readily oxidized.", "Research into how vitamin E prevents the process of lipid peroxidation led to the identification of antioxidants as reducing agents that prevent oxidative reactions, often by scavenging reactive oxygen species before they can damage cells." ], [ "Uses in technology", "=== Food preservatives ===Antioxidants are used as food additives to help guard against food deterioration.", "Exposure to oxygen and sunlight are the two main factors in the oxidation of food, so food is preserved by keeping in the dark and sealing it in containers or even coating it in wax, as with cucumbers.", "However, as oxygen is also important for plant respiration, storing plant materials in anaerobic conditions produces unpleasant flavors and unappealing colors.", "Consequently, packaging of fresh fruits and vegetables contains an ≈8% oxygen atmosphere.", "Antioxidants are an especially important class of preservatives as, unlike bacterial or fungal spoilage, oxidation reactions still occur relatively rapidly in frozen or refrigerated food.", "These preservatives include natural antioxidants such as ascorbic acid (AA, E300) and tocopherols (E306), as well as synthetic antioxidants such as propyl gallate (PG, E310), tertiary butylhydroquinone (TBHQ), butylated hydroxyanisole (BHA, E320) and butylated hydroxytoluene (BHT, E321).Unsaturated fats can be highly susceptible to oxidation, causing rancidification.", "Oxidized lipids are often discolored and can impart unpleasant tastes and flavors.", "Thus, these foods are rarely preserved by drying; instead, they are preserved by smoking, salting, or fermenting.", "Even less fatty foods such as fruits are sprayed with sulfurous antioxidants prior to air drying.", "Metals catalyse oxidation.", "Some fatty foods such as olive oil are partially protected from oxidation by their natural content of antioxidants.", "Fatty foods are sensitive to photooxidation, which forms hydroperoxides by oxidizing unsaturated fatty acids and ester.", "Exposure to ultraviolet (UV) radiation can cause direct photooxidation and decompose peroxides and carbonyl molecules.", "These molecules undergo free radical chain reactions, but antioxidants inhibit them by preventing the oxidation processes.=== Cosmetics preservatives ===Antioxidant stabilizers are also added to fat-based cosmetics such as lipstick and moisturizers to prevent rancidity.", "Antioxidants in cosmetic products prevent oxidation of active ingredients and lipid content.", "For example, phenolic antioxidants such as stilbenes, flavonoids, and hydroxycinnamic acid strongly absorb UV radiation due to the presence of chromophores.", "They reduce oxidative stress from sun exposure by absorbing UV light.=== Industrial uses ===Substituted phenols and derivatives of phenylenediamine are common antioxidants used to inhibit gum formation in gasoline (petrol).Antioxidants may be added to industrial products, such as stabilizers in fuels and additives in lubricants, to prevent oxidation and polymerization that leads to the formation of engine-fouling residues.Fuel additiveComponentsApplicationsAO-22N,N'-di-2-butyl-1,4-phenylenediamineTurbine oils, transformer oils, hydraulic fluids, waxes, and

be protected by antiozonants.", "Oxidation can be accelerated by UV radiation in natural sunlight to cause photo-oxidation.", "Various specialised light stabilisers, such as HALS may be added to plastics to prevent this.", "Synthetic phenolic and aminic antioxidants are increasingly being identified as potential human and environmental health hazards.=== Environmental and health hazards ===Synthetic phenolic antioxidants (SPAs) and aminic antioxidants have potential human and environmental health hazards.", "SPAs are common in indoor dust, small air particles, sediment, sewage, river

DNA damage and mismatches through the cleavage process, generating superoxide radicals.", "DBP is toxic to marine life if exposed long-term.", "Phenolic antioxidants have low biodegradability, but they do not have severe toxicity toward aquatic organisms at low concentrations.", "Another type of antioxidant, diphenylamine (DPA), is commonly used in the production of commercial, industrial lubricants and rubber products and it also acts as a supplement for automotive engine oils." ], [ "Oxidative challenge in biology", "The structure of the antioxidant vitamin ascorbic acid (vitamin C)The vast majority of complex life on Earth requires oxygen for its metabolism, but this same oxygen is a highly reactive element that can damage living organisms.", "Organisms contain chemicals and enzymes that minimize this oxidative damage without interfering with the beneficial effect of oxygen.", "In general, antioxidant systems either prevent these reactive species from being formed, or remove them, thus minimizing their damage.", "Reactive oxygen species can have useful cellular functions, such as redox signaling.", "Thus, ideally, antioxidant systems do not remove oxidants entirely, but maintain them at some optimum concentration.Reactive oxygen species produced in cells include hydrogen peroxide (H2O2), hypochlorous acid (HClO), and free radicals such as the hydroxyl radical (·OH) and the superoxide anion (O2−).", "The hydroxyl radical is particularly unstable and will react rapidly and non-specifically with most biological molecules.", "This species is produced from hydrogen peroxide in metal-catalyzed redox reactions such as the Fenton reaction.", "These oxidants can damage cells by starting chemical chain reactions such as lipid peroxidation, or by oxidizing DNA or proteins.", "Damage to DNA can cause mutations and possibly cancer, if not reversed by DNA repair mechanisms, while damage to proteins causes enzyme inhibition, denaturation and protein degradation.The use of oxygen as part of the process for generating metabolic energy produces reactive oxygen species.", "In this process, the superoxide anion is produced as a by-product of several steps in the electron transport chain.", "Particularly important is the reduction of coenzyme Q in complex III, since a highly reactive free radical is formed as an intermediate (Q'''·'''−).", "This unstable intermediate can lead to electron \"leakage\", when electrons jump directly to oxygen and form the superoxide anion, instead of moving through the normal series of well-controlled reactions of the electron transport chain.", "Peroxide is also produced from the oxidation of reduced flavoproteins, such as complex I.", "However, although these enzymes can produce oxidants, the relative importance of the electron transfer chain to other processes that generate peroxide is unclear.", "In plants, algae, and cyanobacteria, reactive oxygen species are also produced during photosynthesis, particularly under conditions of high light intensity.", "This effect is partly offset by the involvement of carotenoids in photoinhibition, and in algae and cyanobacteria, by large amount of iodide and selenium, which involves these antioxidants reacting with over-reduced forms of the photosynthetic reaction centres to prevent the production of reactive oxygen species.=== Examples of bioactive antioxidant compounds ===Physiological antioxidants are classified into two broad divisions, depending on whether they are soluble in water (hydrophilic) or in lipids (lipophilic).", "In general, water-soluble antioxidants react with oxidants in the cell cytosol and the blood plasma, while lipid-soluble antioxidants protect cell membranes from lipid peroxidation.", "These compounds may be synthesized in the body or obtained from the diet.", "The different antioxidants are present at a wide range of concentrations in body fluids and tissues, with some such as glutathione or ubiquinone mostly present within cells, while others such as uric acid are more systemically distributed (see table below).", "Some antioxidants are only found in a few organisms, and can be pathogens or virulence factors.The interactions between these different antioxidants may be synergistic and interdependent.", "The action of one antioxidant may therefore depend on the proper function of other members of the antioxidant system.", "The amount of protection provided by any one antioxidant will also depend on its concentration, its reactivity towards the particular reactive oxygen species being considered, and the status of the antioxidants with which it interacts.Some compounds contribute to antioxidant defense by chelating transition metals and preventing them from catalyzing the production of free radicals in the cell.", "The ability to sequester iron for iron-binding proteins, such as transferrin and ferritin, is one such function.", "Selenium and zinc are commonly referred to as ''antioxidant minerals'', but these chemical elements have no antioxidant action themselves, but rather are required for the activity of antioxidant enzymes, such as glutathione reductase and superoxide dismutase.", "(See also selenium in biology and zinc in biology.", ")AntioxidantSolubilityConcentration in human serum ()Concentration in liver tissue () Ascorbic acid (vitamin C) Water 50–60 260 (human) Glutathione Water 4 6,400 (human) Lipoic acid Water 0.1–0.7 4–5 (rat) Uric acid Water 200–400 1,600 (human) Carotenes Lipid β-carotene: 0.5–1retinol (vitamin

antioxidant and provides over half of the total antioxidant capacity of human serum.", "Uric acid's antioxidant activities are also complex, given that it does not react with some oxidants, such as superoxide, but does act against peroxynitrite, peroxides, and hypochlorous acid.", "Concerns over elevated UA's contribution to gout must be considered one of many risk factors.", "By itself, UA-related risk of gout at high levels (415–530 μmol/L) is only 0.5% per year with an increase to 4.5% per year at UA supersaturation levels (535+ μmol/L).", "Many of these aforementioned studies determined UA's antioxidant actions within normal physiological levels, and some found antioxidant activity at levels as high as 285 μmol/L.==== Vitamin C ====Ascorbic acid or vitamin C, an oxidation-reduction (redox) catalyst found in both animals and plants, can reduce, and thereby neutralize, reactive oxygen species such as hydrogen peroxide.", "In addition to its direct antioxidant effects, ascorbic acid is also a substrate for the redox enzyme ascorbate peroxidase, a function that is used in stress resistance in plants.", "Ascorbic acid is present at high levels in all parts of plants and can reach concentrations of 20 millimolar in chloroplasts.==== Glutathione ====free radical mechanism of lipid peroxidationGlutathione has antioxidant properties since the thiol group in its cysteine moiety is a reducing agent and can be reversibly oxidized and reduced.", "In cells, glutathione is maintained in the reduced form by the enzyme glutathione reductase and in turn reduces other metabolites and enzyme systems, such as ascorbate in the glutathione-ascorbate cycle, glutathione peroxidases and glutaredoxins, as well as reacting directly with oxidants.", "Due to its high concentration and its central role in maintaining the cell's redox state, glutathione is one of the most important cellular antioxidants.", "In some organisms glutathione is replaced by other thiols, such as by mycothiol in the Actinomycetes, bacillithiol in some gram-positive bacteria, or by trypanothione in the Kinetoplastids.==== Vitamin E ====Vitamin E is the collective name for a set of eight related tocopherols and tocotrienols, which are fat-soluble vitamins with antioxidant properties.", "Of these, α-tocopherol has been most studied as it has the highest bioavailability, with the body preferentially absorbing and metabolising this form.It has been claimed that the α-tocopherol form is the most important lipid-soluble antioxidant, and that it protects membranes from oxidation by reacting with lipid radicals produced in the lipid peroxidation chain reaction.", "This removes the free radical intermediates and prevents the propagation reaction from continuing.", "This reaction produces oxidised α-tocopheroxyl radicals that can be recycled back to the active reduced form through reduction by other antioxidants, such as ascorbate, retinol or ubiquinol.", "This is in line with findings showing that α-tocopherol, but not water-soluble antioxidants, efficiently protects glutathione peroxidase 4 (GPX4)-deficient cells from cell death.", "GPx4 is the only known enzyme that efficiently reduces lipid-hydroperoxides within biological membranes.However, the roles and importance of the various forms of vitamin E are presently unclear, and it has even been suggested that the most important function of α-tocopherol is as a signaling molecule, with this molecule having no significant role in antioxidant metabolism.", "The functions of the other forms of vitamin E are even less well understood, although γ-tocopherol is a nucleophile that may react with electrophilic mutagens, and tocotrienols may be important in protecting neurons from damage.=== Pro-oxidant activities ===Antioxidants that are reducing agents can also act as pro-oxidants.", "For example, vitamin C has antioxidant activity when it reduces oxidizing substances such as hydrogen peroxide; however, it will also reduce metal ions such as iron and copper that generate free radicals through the Fenton reaction.", "While ascorbic acid is effective antioxidant, it can also oxidatively change the flavor and color of food.", "With the presence of transition metals, there are low concentrations of ascorbic acid that can act as a radical scavenger in the Fenton reaction.2 Fe3+ + Ascorbate → 2 Fe2+ + Dehydroascorbate2 Fe2+ + 2 H2O2 → 2 Fe3+ + 2 OH'''·''' + 2 OH−The relative importance of the antioxidant and pro-oxidant activities of antioxidants is an area of current research, but vitamin C, which exerts its effects as a vitamin by oxidizing polypeptides, appears to have a mostly antioxidant action in the human body.=== Enzyme systems ===As with the chemical antioxidants, cells are protected against oxidative stress by an interacting network of antioxidant enzymes.", "Here, the superoxide released by processes such as oxidative phosphorylation is first converted to hydrogen peroxide and then further reduced to give water.", "This detoxification pathway is the result of multiple enzymes, with superoxide dismutases catalysing the first step and then catalases and various peroxidases removing hydrogen peroxide.", "As with antioxidant metabolites, the contributions of these enzymes to antioxidant defenses can be hard to separate from one another, but the generation of transgenic mice lacking just one antioxidant enzyme can be informative.==== Superoxide dismutase, catalase, and peroxiredoxins ====Superoxide dismutases (SODs) are a class of closely related enzymes that catalyze the breakdown of the superoxide anion into oxygen and hydrogen peroxide.", "SOD enzymes are present in almost all aerobic cells and in extracellular fluids.", "Superoxide dismutase enzymes contain metal ion cofactors that, depending on the isozyme, can be copper, zinc, manganese or iron.", "In humans, the copper/zinc SOD is present in the cytosol, while manganese SOD is present in the mitochondrion.", "There also exists a third form of SOD in extracellular fluids, which contains copper and zinc in its active sites.", "The mitochondrial isozyme seems to be the most biologically important of these three, since mice lacking this enzyme die soon after birth.", "In contrast, the mice lacking copper/zinc SOD (Sod1) are viable but have numerous pathologies and a reduced lifespan (see article on superoxide), while mice without the extracellular SOD have minimal defects (sensitive to hyperoxia).", "In plants, SOD isozymes are present in the cytosol and mitochondria, with an iron SOD found in chloroplasts that is absent from vertebrates and yeast.Catalases are enzymes that catalyse the conversion of hydrogen peroxide to water and oxygen, using either an iron or manganese cofactor.", "This protein is localized to peroxisomes in most eukaryotic cells.", "Catalase is an unusual enzyme since, although hydrogen peroxide is its only substrate, it follows a ping-pong mechanism.", "Here, its cofactor is oxidised by one molecule of hydrogen peroxide and then regenerated by transferring the bound oxygen to a second molecule of substrate.", "Despite its apparent importance in hydrogen peroxide removal, humans with genetic deficiency of catalase — \"acatalasemia\" — or mice genetically engineered to lack catalase completely, experience few ill effects.Decameric structure of AhpC, a bacterial 2-cysteine peroxiredoxin from ''Salmonella typhimurium''Peroxiredoxins are peroxidases that catalyze the reduction of hydrogen peroxide, organic hydroperoxides, as well as peroxynitrite.", "They are divided into three classes: typical 2-cysteine peroxiredoxins; atypical 2-cysteine peroxiredoxins; and 1-cysteine peroxiredoxins.", "These enzymes share the same basic catalytic mechanism, in which a redox-active cysteine (the peroxidatic cysteine) in the active site is oxidized to a sulfenic acid by the peroxide substrate.", "Over-oxidation of this cysteine residue in peroxiredoxins inactivates these enzymes, but this can be reversed by the action of sulfiredoxin.", "Peroxiredoxins seem to be important in antioxidant metabolism, as mice lacking peroxiredoxin 1 or 2 have shortened lifespans and develop hemolytic anaemia, while plants use peroxiredoxins to remove hydrogen peroxide generated in chloroplasts.==== Thioredoxin and glutathione systems ====The thioredoxin system contains the 12-kDa protein thioredoxin and its companion thioredoxin reductase.", "Proteins related to thioredoxin are present in all sequenced organisms.", "Plants, such as ''Arabidopsis thaliana,'' have a particularly great diversity of isoforms.", "The active site of thioredoxin consists of two neighboring cysteines, as part of a highly conserved CXXC motif, that can cycle between an active dithiol form (reduced) and an oxidized disulfide form.", "In its active state, thioredoxin acts as an efficient reducing agent, scavenging reactive oxygen species and maintaining other proteins in their reduced state.", "After being oxidized, the active thioredoxin is regenerated by the action of thioredoxin reductase, using NADPH as an electron donor.The glutathione system includes glutathione, glutathione reductase, glutathione peroxidases, and glutathione ''S''-transferases.", "This system is found in animals, plants and microorganisms.", "Glutathione peroxidase is an enzyme containing four selenium-cofactors that catalyzes the breakdown of hydrogen peroxide and organic hydroperoxides.", "There are at least four different glutathione peroxidase isozymes in animals.", "Glutathione peroxidase 1 is the most abundant and is a very efficient scavenger of hydrogen peroxide, while glutathione peroxidase 4 is most active with lipid hydroperoxides.", "Surprisingly, glutathione peroxidase 1 is dispensable, as mice lacking this enzyme have normal lifespans, but they are hypersensitive to induced oxidative stress.", "In addition, the glutathione ''S''-transferases show high activity with lipid peroxides.", "These enzymes are at particularly high levels in the liver and also serve in detoxification metabolism." ], [ "Health research", "=== Relation to diet ===The dietary antioxidant vitamins A, C, and E are essential and required in specific daily amounts to prevent diseases.", "Polyphenols, which have antioxidant properties in vitro due to their free hydroxy groups, are extensively metabolized by catechol-O-methyltransferase which methylates free hydroxyl groups, and thereby prevents them from acting as antioxidants in vivo.===Interactions===Common pharmaceuticals (and supplements) with antioxidant properties may interfere with the efficacy of certain anticancer medication and radiation therapy.", "Pharmaceuticals and supplements that have antioxidant properties suppress the formation of free radicals by inhibiting oxidation processes.", "Radiation therapy induce oxidative stress that damages essential components of cancer cells, such as proteins, nucleic acids, and lipids that comprise cell membranes.=== Adverse effects ===Structure of the metal chelator phytic acidRelatively strong reducing acids can have antinutrient effects by binding to dietary minerals such as iron and zinc in the gastrointestinal tract and preventing them from being absorbed.", "Examples are oxalic acid, tannins and phytic acid, which are high in plant-based diets.", "Calcium and iron deficiencies are not uncommon in diets in developing countries where less meat is eaten and there is high consumption of phytic acid from beans and unleavened whole grain bread.", "However, germination, soaking, or microbial fermentation are all household strategies that reduce the phytate and polyphenol content of unrefined cereal.", "Increases in Fe, Zn and Ca absorption have been reported in adults fed dephytinized cereals compared with cereals containing their native phytate.FoodsReducing acid presentCocoa bean and chocolate, spinach, turnip and rhubarbOxalic acidWhole grains, maize, legumesPhytic acidTea, beans, cabbageTanninsHigh doses of some antioxidants may have harmful long-term effects.", "The ''Beta-Carotene and Retinol Efficacy Trial'' (CARET) study of lung cancer patients found that smokers given supplements containing beta-carotene and vitamin A had increased rates of lung cancer.", "Subsequent studies confirmed these adverse effects.", "These harmful effects may also be seen in non-smokers, as one meta-analysis including data from approximately 230,000 patients showed that β-carotene, vitamin A or vitamin E supplementation is associated with increased mortality, but saw no significant effect from vitamin C. No health risk was seen when all the randomized controlled studies were examined together, but an increase in mortality was detected when only high-quality and low-bias risk trials were examined separately.", "As the majority of these low-bias trials dealt with either elderly people, or people with disease, these results may not apply to the general population.", "This meta-analysis was later repeated and extended by the same authors, confirming the previous results.", "These two publications are consistent with some previous meta-analyses that also suggested that vitamin E supplementation increased mortality, and that antioxidant supplements increased the risk of colon cancer.", "Beta-carotene may also increase lung cancer.", "Overall, the large number of clinical trials carried out on antioxidant supplements suggest that either these products have no effect on health, or that they cause a small increase in mortality in elderly or vulnerable populations.=== Exercise and muscle soreness ===A 2017 review showed that taking antioxidant dietary supplements before or after exercise is unlikely to produce a noticeable reduction in muscle soreness after a person exercises." ], [ "Levels in food", "Fruits and vegetables are good sources of antioxidant vitamins C and E.Antioxidant vitamins are found in vegetables, fruits, eggs, legumes and nuts.", "Vitamins A, C, and E can be destroyed by long-term storage or prolonged cooking.", "The effects of cooking and food processing are complex, as these processes can also increase the bioavailability of antioxidants, such as some carotenoids in vegetables.", "Processed food contains fewer antioxidant vitamins than fresh and uncooked foods, as preparation exposes food to heat and oxygen.Antioxidant vitaminsFoods containing high levels of antioxidant vitamins Vitamin C (ascorbic acid) Fresh or frozen fruits and vegetables Vitamin E (tocopherols, tocotrienols) Vegetable oils, nuts, and seeds Carotenoids (carotenes as provitamin A) Fruit, vegetables and eggsOther antioxidants are not obtained from the diet, but instead are made in the body.", "For example, ubiquinol (coenzyme Q) is poorly absorbed from the gut and is made through the mevalonate pathway.", "Another example is glutathione, which is made from amino acids.", "As any glutathione in the gut is broken down to free cysteine, glycine and glutamic acid before being absorbed, even large oral intake has little effect on the concentration of glutathione in the body.", "Although large amounts of sulfur-containing amino acids such as acetylcysteine can increase glutathione, no evidence exists that eating high levels of these glutathione precursors is beneficial for healthy adults.=== Measurement and invalidation of ORAC ===Measurement of polyphenol and carotenoid content in food is not a straightforward process, as antioxidants collectively are a diverse group of compounds with different reactivities to various reactive oxygen species.", "In food science analyses in vitro, the oxygen radical absorbance capacity (ORAC) was once an industry standard for estimating antioxidant strength of whole foods, juices and food additives, mainly from the presence of polyphenols.", "Earlier measurements and ratings by the United States Department of Agriculture were withdrawn in 2012 as biologically irrelevant to human health, referring to an absence of physiological evidence for polyphenols having antioxidant properties ''in vivo''.", "Consequently, the ORAC method, derived only from ''in vitro'' experiments, is no longer considered relevant to human diets or biology, as of 2010.Alternative in vitro measurements of antioxidant content in foods – also based on the presence of polyphenols – include the Folin-Ciocalteu reagent, and the Trolox equivalent antioxidant capacity assay." ], [ "References" ], [ "Further reading", "* * *" ], [ "External links", "*" ] ]

[ [ "Brass" ], [ "Introduction", "Islamic Golden Age Brass astrolabeBrass lectern with an eagle.", "Attributed to Aert van Tricht, Limburg (Netherlands), c.", "1500.", "'''Brass''' is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic, and chemical properties, but copper typically has the larger proportion.", "In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.Brass is similar to bronze, a copper alloy that contains tin instead of zinc.", "Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si).", "Historically, the distinction between the two alloys has been less consistent and clear, and increasingly museums use the more general term \"copper alloy.", "\"Brass has long been a popular material for its bright gold-like appearance and is still used for drawer pulls and doorknobs.", "It has also been widely used to make sculpture and utensils because of its low melting point, high workability (both with hand tools and with modern turning and milling machines), durability, and electrical and thermal conductivity.", "Brasses with higher copper content are softer and more golden in colour; conversely those with less copper and thus more zinc are harder and more silvery in colour.Brass is still commonly used in applications where corrosion resistance and low friction are required, such as locks, hinges, gears, bearings, ammunition casings, zippers, plumbing, hose couplings, valves, and electrical plugs and sockets.", "It is used extensively for musical instruments such as horns and bells.", "The composition of brass, generally 66% copper and 34% zinc, makes it a favorable substitute for copper in costume jewelry and fashion jewelry, as it exhibits greater resistance to corrosion.", "Brass is not as hard as bronze, and so is not suitable for most weapons and tools.", "Nor is it suitable for marine uses, because the zinc reacts with minerals in salt water, leaving porous copper behind; marine brass, with added tin, avoids this, as does bronze.Brass is often used in situations in which it is important that sparks not be struck, such as in fittings and tools used near flammable or explosive materials." ], [ "Properties", "Microstructure of rolled and annealed brass (400× magnification)Brass is more malleable than bronze or zinc.", "The relatively low melting point of brass (, depending on composition) and its flow characteristics make it a relatively easy material to cast.", "By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard and soft brasses.", "The density of brass is .Today, almost 90% of all brass alloys are recycled.", "Because brass is not ferromagnetic, ferrous scrap can be separated from it by passing the scrap near a powerful magnet.", "Brass scrap is melted and recast into billets that are extruded into the desired form and size.", "The general softness of brass means that it can often be machined without the use of cutting fluid, though there are exceptions to this.Aluminium makes brass stronger and more corrosion-resistant.", "Aluminium also causes a highly beneficial hard layer of aluminium oxide (Al2O3) to be formed on the surface that is thin, transparent, and self-healing.", "Tin has a similar effect and finds its use especially in seawater applications (naval brasses).", "Combinations of iron, aluminium, silicon, and manganese make brass wear- and tear-resistant.", "The addition of as little as 1% iron to a brass alloy will result in an alloy with a noticeable magnetic attraction.Binary phase diagramBrass will corrode in the presence of moisture, chlorides, acetates, ammonia, and certain acids.", "This often happens when the copper reacts with sulfur to form a brown and eventually black surface layer of copper sulfide which, if regularly exposed to slightly acidic water such as urban rainwater, can then oxidize in air to form a patina of green-blue copper carbonate.", "Depending on how the patina layer was formed, it may protect the underlying brass from further damage.Although copper and zinc have a large difference in electrical potential, the resulting brass alloy does not experience internalized galvanic corrosion because of the absence of a corrosive environment within the mixture.", "However, if brass is placed in contact with a more noble metal such as silver or gold in such an environment, the brass will corrode galvanically; conversely, if brass is in contact with a less-noble metal such as zinc or iron, the less noble metal will corrode and the brass will be protected." ], [ "Lead content", "To enhance the machinability of brass, lead is often added in concentrations of about 2%.", "Since lead has a lower melting point than the other constituents of the brass, it tends to migrate towards the grain boundaries in the form of globules as it cools from casting.", "The pattern the globules form on the surface of the brass increases the available lead surface area which, in turn, affects the degree of leaching.", "In addition, cutting operations can smear the lead globules over the surface.", "These effects can lead to significant lead leaching from brasses of comparatively low lead content.In October 1999, the California State Attorney General sued 13 key manufacturers and distributors over lead content.", "In laboratory tests, state researchers found the average brass key, new or old, exceeded the California Proposition 65 limits by an average factor of 19, assuming handling twice a day.", "In April 2001 manufacturers agreed to reduce lead content to 1.5%, or face a requirement to warn consumers about lead content.", "Keys plated with other metals are not affected by the settlement, and may continue to use brass alloys with a higher percentage of lead content.Also in California, lead-free materials must be used for \"each component that comes into contact with the wetted surface of pipes and pipe fittings, plumbing fittings and fixtures\".", "On 1 January 2010, the maximum amount of lead in \"lead-free brass\" in California was reduced from 4% to 0.25% lead." ], [ "Corrosion-resistant brass for harsh environments", "Brass sampling cock with stainless steel handle Dezincification-resistant (DZR or DR) brasses, sometimes referred to as CR (corrosion resistant) brasses, are used where there is a large corrosion risk and where normal brasses do not meet the requirements.", "Applications with high water temperatures, chlorides

high malleability and workability, relatively good resistance to corrosion, and traditionally attributed acoustic properties of brass, have made it the usual metal of choice for construction of musical instruments whose acoustic resonators consist of long, relatively narrow tubing, often folded or coiled for compactness; silver and its alloys, and even gold, have been used for the same reasons, but brass is the most economical choice.", "Collectively known as brass instruments, these include the trombone, tuba, trumpet, cornet, flugelhorn, baritone horn, euphonium, tenor horn, and French horn, and many other \"horns\", many in variously sized families, such as the saxhorns.Other wind instruments may be constructed of brass or other metals, and indeed most modern student-model flutes and piccolos are made of some variety of brass, usually a cupronickel alloy similar to nickel silver (also known as German silver).", "Clarinets, especially low clarinets such as the contrabass and subcontrabass, are sometimes made of metal because of limited supplies of the dense, fine-grained tropical hardwoods traditionally preferred for smaller woodwinds.", "For the same reason, some low clarinets, bassoons and contrabassoons feature a hybrid construction, with long, straight sections of wood, and curved joints, neck, and/or bell of metal.", "The use of metal also avoids the risks of exposing wooden instruments to changes in temperature or humidity, which can cause sudden cracking.", "Even though the saxophones and sarrusophones are classified as woodwind instruments, they are normally made of brass for similar reasons, and because their wide, conical bores and thin-walled bodies are more easily and efficiently made by forming sheet metal than by machining wood.The keywork of most modern woodwinds, including wooden-bodied instruments, is also usually made of an alloy such as nickel silver.", "Such alloys are stiffer and more durable than the brass used to construct the instrument bodies, but still workable with simple hand tools—a boon to quick repairs.", "The mouthpieces of both brass instruments and, less commonly, woodwind instruments are often made of brass

\"brass\" to translate \"nechosheth\" (bronze or copper) from Hebrew to English.", "The earliest brasses may have been natural alloys made by smelting zinc-rich copper ores.", "By the Roman period brass was being deliberately produced from metallic copper and zinc minerals using the cementation process, the product of which was calamine brass, and variations on this method continued until the mid-19th century.", "It was eventually replaced by speltering, the direct alloying of copper and zinc metal which was introduced to Europe in the 16th century.Brass has sometimes historically been referred to as \"yellow copper\".===Early copper-zinc alloys===In West Asia and the Eastern Mediterranean early copper-zinc alloys are now known in small numbers from a number of 3rd millennium BC sites in the Aegean, Iraq, the United Arab Emirates, Kalmykia, Turkmenistan and Georgia and from 2nd millennium BC sites in western India, Uzbekistan, Iran, Syria, Iraq and Canaan.", "Isolated examples of copper-zinc alloys are known in China from the 1st century AD, long after bronze was widely used.The compositions of these early \"brass\" objects are highly variable and most have zinc contents of between 5% and 15% wt which is lower than in brass produced by cementation.", "These may be \"natural alloys\" manufactured by smelting zinc rich copper ores in redox conditions.", "Many have similar tin contents to contemporary bronze artefacts and it is possible that some copper-zinc alloys were accidental and perhaps not even distinguished from copper.", "However the large number of copper-zinc alloys now known suggests that at least some were deliberately manufactured and many have zinc contents of more than 12% wt which would have resulted in a distinctive golden colour.By the 8th–7th century BC Assyrian cuneiform tablets mention the exploitation of the \"copper of the mountains\" and this may refer to \"natural\" brass.", "\"Oreikhalkon\" (mountain copper), the Ancient Greek translation of this term, was later adapted to the Latin ''aurichalcum'' meaning \"golden copper\" which became the standard term for brass.", "In the 4th century BC Plato knew ''orichalkos'' as rare and nearly as valuable as gold and Pliny describes how ''aurichalcum'' had come from Cypriot ore deposits which had been exhausted by the 1st century AD.", "X-ray fluorescence analysis of 39 orichalcum ingots recovered from a 2,600-year-old shipwreck off Sicily found them to be an alloy made with 75–80% copper, 15–20% zinc and small percentages of nickel, lead and iron.===Roman world===7th-century Persian ewer in brass with copper inlay, Walters Art Museum, Baltimore, Maryland, USADuring the later part of first millennium BC the use of brass spread across a wide geographical area from Britain and Spain in the west to Iran, and India in the east.", "This seems to have been encouraged by exports and influence from the Middle East and eastern Mediterranean where deliberate production of brass from metallic copper and zinc ores had been introduced.", "The 4th century BC writer Theopompus, quoted by Strabo, describes how heating earth from Andeira in Turkey produced \"droplets of false silver\", probably metallic zinc, which could be used to turn copper into oreichalkos.", "In the 1st century BC the Greek Dioscorides seems to have recognized a link between zinc minerals and brass describing how Cadmia (zinc oxide) was found on the walls of furnaces used to heat either zinc ore or copper and explaining that it can then be used to make brass.By the first century BC brass was available in sufficient supply to use as coinage in Phrygia and Bithynia, and after the Augustan currency reform of 23 BC it was also used to make Roman ''dupondii'' and ''sestertii''.", "The uniform use of brass for coinage and military equipment across the Roman world may indicate a degree of state involvement in the industry, and brass even seems to have been deliberately boycotted by Jewish communities in Palestine because of its association with Roman authority.", "Brass was produced by the cementation process where copper and zinc ore are heated together until zinc vapor is produced which reacts with the copper.", "There is good archaeological evidence for this process and crucibles used to produce brass by cementation have been found on Roman period sites including Xanten and Nidda in Germany, Lyon in France and at a number of sites in Britain.", "They vary in size from tiny acorn sized to large amphorae like vessels but all have elevated levels of zinc on the interior and are lidded.", "They show no signs of slag or metal prills suggesting that zinc minerals were heated to produce zinc vapor which reacted with metallic copper in a solid state reaction.", "The fabric of these crucibles is porous, probably designed to prevent a buildup of pressure, and many have small holes in the lids which may be designed to release pressure or to add additional zinc minerals near the end of the process.", "Dioscorides mentioned that zinc minerals were used for both the working and finishing of brass, perhaps suggesting secondary additions.Brass made during the early Roman period seems to have varied between 20% and 28% wt zinc.", "The high content of zinc in coinage and brass objects declined after the first century AD and it has been suggested that this reflects zinc loss during recycling and thus an interruption in the production of new brass.", "However it is now thought this was probably a deliberate change in composition and overall the use of brass increases over this period making up around 40% of all copper alloys used in the Roman world by the 4th century AD.===Medieval period===Baptism of Christ'' on the 12th-century baptismal font at St Bartholomew's Church, LiègeLittle is known about the production of brass during the centuries immediately after the collapse of the Roman Empire.", "Disruption in the trade of tin for bronze from Western Europe may have contributed to the increasing popularity of brass in the east and by the 6th–7th centuries AD over 90% of copper alloy artefacts from Egypt were made of brass.", "However other alloys such as low tin bronze were also used and they vary depending on local cultural attitudes, the purpose of the metal and access to zinc, especially between the Islamic and Byzantine world.", "Conversely the use of true brass seems to have declined in Western Europe during this period in favor of gunmetals and other mixed alloys but by about 1000 brass artefacts are found in Scandinavian graves in Scotland, brass was being used in the manufacture of coins in Northumbria and there is archaeological and historical evidence for the production of calamine brass in Germany and the Low Countries, areas rich in calamine ore.These places would remain important centres of brass making throughout the Middle Ages period, especially Dinant.", "Brass objects are still collectively known as ''dinanderie'' in French.", "The baptismal font at St Bartholomew's Church, Liège in modern Belgium (before 1117) is an outstanding masterpiece of Romanesque brass casting, though also often described as bronze.", "The metal of the early 12th-century Gloucester Candlestick is unusual even by medieval standards in being a mixture of copper, zinc, tin, lead, nickel, iron, antimony and arsenic with an unusually large amount of silver, ranging from 22.5% in the base to 5.76% in the pan below the candle.", "The proportions of this mixture may suggest that the candlestick was made from a hoard of old coins, probably Late Roman.", "Latten is a term for medieval alloys of uncertain and often variable composition often covering decorative borders and similar objects cut from sheet metal, whether of brass or bronze.", "Especially in Tibetan art, analysis of some objects shows very different compositions from different ends of a large piece.", "Aquamaniles were typically made in brass in both the European and Islamic worlds.Brass aquamanile from Lower Saxony, Germany, c. 1250The cementation process continued to be used but literary sources from both Europe and the Islamic world seem to describe variants of a higher temperature liquid process which took place in open-topped crucibles.", "Islamic cementation seems to have used zinc oxide known as ''tutiya'' or tutty rather than zinc ores for brass-making, resulting in a metal with lower iron impurities.", "A number of Islamic writers and the 13th century Italian Marco Polo describe how this was obtained by sublimation from zinc ores and condensed onto clay or iron bars, archaeological examples of which have been identified at Kush in Iran.", "It could then be used for brass making or medicinal purposes.", "In 10th century Yemen al-Hamdani described how spreading al-iglimiya, probably zinc oxide, onto the surface of molten copper produced tutiya vapor which then reacted with the metal.", "The 13th century Iranian writer al-Kashani describes a more complex process whereby ''tutiya'' was mixed with raisins and gently roasted before being added to the surface of the molten metal.", "A temporary lid was added at this point presumably to minimize the escape of zinc vapor.In Europe a similar liquid process in open-topped crucibles took place which was probably less efficient than the Roman process and the use of the term tutty by Albertus Magnus in the 13th century suggests influence from Islamic technology.", "The 12th century German monk Theophilus described how preheated crucibles were one sixth filled with powdered calamine and charcoal then topped up with copper and charcoal before being melted, stirred then filled again.", "The final product was cast, then again melted with calamine.", "It has been suggested that this second melting may have taken place at a lower temperature to allow more zinc to be absorbed.", "Albertus Magnus noted that the \"power\" of both calamine and tutty could evaporate and described how the addition of powdered glass could create a film to bind it to the metal.", "German brass making crucibles are known from Dortmund dating to the 10th century AD and from Soest and Schwerte in Westphalia dating to around the 13th century confirm Theophilus' account, as they are open-topped, although ceramic discs from Soest may have served as loose lids which may have been used to reduce zinc evaporation, and have slag on the interior resulting from a liquid process.===Africa===12th century \"Bronze Head from Ife\", actually of \"heavily leaded zinc-brass\"Some of the most famous objects in African art are the lost wax castings of West Africa, mostly from what is now Nigeria, produced first by the Kingdom of Ife and then the Benin Empire.", "Though normally described as \"bronzes\", the Benin Bronzes, now mostly in the British Museum and other Western collections, and the large portrait heads such as the Bronze Head from Ife of \"heavily leaded zinc-brass\" and the Bronze Head of Queen Idia, both also British Museum, are better described as brass, though of variable compositions.", "Work in brass or bronze continued to be important in Benin art and other West African traditions such as Akan goldweights, where the metal was regarded as a more valuable material than in Europe.===Renaissance and post-medieval Europe===The Renaissance saw important changes to both the theory and practice of brassmaking in Europe.", "By the 15th century there is evidence for the renewed use of lidded cementation crucibles at Zwickau in Germany.", "These large crucibles were capable of producing c.20 kg of brass.", "There are traces of slag and pieces of metal on the interior.", "Their irregular composition suggests that this was a lower temperature, not entirely liquid, process.", "The crucible lids had small holes which were blocked with clay plugs near the end of the process presumably to maximize zinc absorption in the final stages.", "Triangular crucibles were then used to melt the brass for casting.16th-century technical writers such as Biringuccio, Ercker and Agricola described a variety of cementation brass making techniques and came closer to understanding the true nature of the process noting that copper became heavier as it changed to brass and that it became more golden as additional calamine was added.", "Zinc metal was also becoming more commonplace.", "By 1513 metallic zinc ingots from India and China were arriving in London and pellets of zinc condensed in furnace flues at the Rammelsberg in Germany were exploited for cementation brass making from around 1550.Eventually it was discovered that metallic zinc could be alloyed with copper to make brass, a process known as speltering, and by 1657 the German chemist Johann Glauber had recognized that calamine was \"nothing else but unmeltable zinc\" and that zinc was a \"half ripe metal\".", "However some earlier high zinc, low iron brasses such as the 1530 Wightman brass memorial plaque from England may have been made by alloying copper with ''zinc'' and include traces of cadmium similar to those found in some zinc ingots from China.", "However, the cementation process was not abandoned, and as late as the early 19th century there are descriptions of solid-state cementation in a domed furnace at around 900–950 °C and lasting up to 10 hours.", "The European brass industry continued to flourish into the post medieval period buoyed by innovations such as the 16th century introduction of water powered hammers for the production of wares such as pots.", "By 1559 the Germany city of Aachen alone was capable of producing 300,000 cwt of brass per year.", "After several false starts during the 16th and 17th centuries the brass industry was also established in England taking advantage of abundant supplies of cheap copper smelted in the new coal fired reverberatory furnace.", "In 1723 Bristol brass maker Nehemiah Champion patented the use of granulated copper, produced by pouring molten metal into cold water.", "This increased the surface area of the copper helping it react and zinc contents of up to 33% wt were reported using this new technique.In 1738 Nehemiah's son William Champion patented a technique for the first industrial scale distillation of metallic zinc known as ''distillation per descencum'' or \"the English process\".", "This local zinc was used in speltering and allowed greater control over the zinc content of brass and the production of high-zinc copper alloys which would have been difficult or impossible to produce using cementation, for use in expensive objects such as scientific instruments, clocks, brass buttons and costume jewelry.", "However Champion continued to use the cheaper calamine cementation method to produce lower-zinc brass and the archaeological remains of bee-hive shaped cementation furnaces have been identified at his works at Warmley.", "By the mid-to-late 18th century developments in cheaper zinc distillation such as John-Jaques Dony's horizontal furnaces in Belgium and the reduction of tariffs on zinc as well as demand for corrosion-resistant high zinc alloys increased the popularity of speltering and as a result cementation was largely abandoned by the mid-19th century." ], [ "See also", "*Brass bed*Brass

around the world, mostly because of its performance and entertainment aspects.", "Ballroom dancing is also widely enjoyed on stage, film, and television.", "''Ballroom dance'' may refer, at its widest definition, to almost any recreational dance with a partner.", "However, with the emergence of dance competition (now known as Dancesport), two principal schools have emerged and the term is used more narrowly to refer to the dances recognized by those schools.", "* The International School, originally developed in England and now regulated by the World Dance Council ( WDC) and the World DanceSport Federation ( WDSF), is most prevalent in Europe.", "It encompasses two categories, Standard and Latin, each of which consist of five dances—International Waltz, International Tango, International Viennese Waltz, International Slow Foxtrot, and International Quickstep in the Standard category and International Samba, International Cha Cha, International Rumba, International Paso Doble, and International Jive in the Latin category.", "A \"Standard\" or \"Latin\" competition encompasses all five dances in the respective category, and a \"Ten Dance\" competition encompasses all ten dances.", "The two styles, while differing in technique, rhythm, and costumes, exemplify core elements of ballroom dancing such as control and cohesiveness.", "* The American School, also called North American School, is most prevalent in the United States and Canada, where it is regulated by USA Dance and Canada Dancesport ( CDS) -- the respective national member bodies of the WDSF.", "It also consists of two categories analogous to the Standard and Latin categories of the International School, respectively called Smooth and Rhythm.", "The Smooth category consists of only four dances—American Waltz, American Tango, American Foxtrot, and American Viennese Waltz, omitting American Peabody (the American School equivalent to Quickstep) -- while the dances selected for competition in the Rhythm category are American Cha Cha, American Rumba, American East Coast Swing (the American School equivalent to International Jive), American Bolero, and American Mambo.", "A \"Smooth\" or \"Rhythm\" competition encompasses the dances in the respective category, and a \"Nine Dance\" competition encompassing all nine of these dances is analogous to the \"Ten Dance\" competition of the International School.", "USA Dance additionally recognizes American Peabody, American Merengue, American Paso Doble, American Samba, American West Coast Swing, American Polka, and American Hustle as ballroom dances in which sanctioned competition may take place.Note that dances of the two schools that bear the same name may differ considerably in permitted patterns (figures), technique, and styling.Exhibitions and social situations that feature ballroom dancing also may include additional partner dances such as Lindy Hop, Night Club Two Step, Night Club Swing, Bachata, Country Two Step, and regional (local or national) favorites that normally are not regarded as part of the ballroom family, and a number of historical dances also may be danced in ballrooms or salons.", "Additionally, some sources regard Sequence Dancing, in pairs or other formations, to be a style of ballroom dance." ], [ "Definitions and history", "Galliard in Siena, Italy, 15th centuryThe term 'ballroom dancing' is derived from the word ''ball'' which in turn originates from the Latin word ''ballare'' which means 'to dance' (a ball-room being a large room specially designed for such dances).", "In times past, ballroom dancing was social dancing for the privileged, leaving folk dancing for the lower classes.", "These boundaries have since become blurred.", "The definition of ballroom dance also depends on the era: balls have featured popular dances of the day such as the Minuet, Quadrille, Polonaise, Polka, Mazurka, and others, which are now considered to be historical dances.=== Early modern period ===The first authoritative knowledge of the earliest ballroom dances was recorded toward the end of the 16th century, when Jehan Tabourot, under the pen name \"Thoinot-Arbeau\", published in 1588 his ''Orchésographie'', a study of late 16th-century French renaissance social dance.", "Among the dances described were the solemn basse danse, the livelier branle, pavane, and the galliarde which Shakespeare called the \"cinq pace\" as it was made of five steps.In 1650, the Minuet, originally a peasant dance of Poitou, was introduced into Paris and set to music by Jean-Baptiste Lully and danced by the King Louis XIV in public.", "The Minuet dominated the ballroom from that time until the close of the 18th century.Toward the later half of the 17th century, Louis XIV founded his 'Académie Royale de Musique et de Danse', where specific rules for the execution of every dance and the \"five positions\" of the feet were formulated for the first time by members of the Académie.", "Eventually, the first definite cleavage between ballet and ballroom came when professional dancers appeared in the ballets, and the ballets left the Court and went to the stage.", "Ballet technique such as the turned out positions of the feet, however, lingered for over two centuries and past the end of the Victoria era.===19th century===The waltz with its modern hold took root in England in about 1812; in 1819 Carl Maria von Weber wrote ''Invitation to the Dance'', which marked the adoption of the waltz form into the sphere of absolute music.", "The dance was initially met with tremendous opposition due to the semblance of impropriety associated with the closed hold, though the stance gradually softened.", "In the 1840s several new dances made their appearance in the ballroom, including the polka, mazurka, and the Schottische.", "In the meantime a strong tendency emerged to drop all 'decorative' steps such as ''entrechats'' and ''ronds de jambes'' that had found a place in the Quadrilles and other dances.=== Early 20th century ===Vernon and Irene Castle, early ballroom dance pioneers, –18Modern ballroom dance has its roots early in the 20th century, when several different things happened more or less at the same time.", "The first was a movement away from the sequence dances towards dances where the couples moved independently.", "This had been pre-figured by the waltz, which had already made this transition.", "The second was a wave of popular music, such as jazz.", "Since dance is to a large extent tied to music, this led to a burst of newly invented dances.", "There were many dance crazes in the period 1910–1930.The third event was a concerted effort to transform some of the dance crazes into dances which could be taught to a wider dance public in the U.S. and Europe.", "Here Vernon and Irene Castle were important, and so was a generation of English dancers in the 1920s, including Josephine Bradley and Victor Silvester.", "These professionals analysed, codified, published, and taught a number of standard dances.", "It was essential, if popular dance was to flourish, for dancers to have some basic movements they could confidently perform with any partner they might meet.", "Here the huge Arthur Murray organisation in America, and the dance societies in England, such as the Imperial Society of Teachers of Dancing, were highly influential.", "Finally, much of this happened during and after a period of World War, and the effect of such a conflict in dissolving older social customs was considerable.Later, in the 1930s, the on-screen dance pairing of Fred Astaire and Ginger Rogers influenced all forms of dance in the U.S. and elsewhere.", "Although both actors had separate careers, their filmed dance sequences together, which included portrayals of the Castles, have reached iconic status.", "Much of Astaire and Rogers' work portrayed social dancing, although the performances were highly choreographed (often by Astaire or Hermes Pan) and meticulously staged and rehearsed." ], [ "Competitive dancing", "Cha-cha-cha dance at competitions in Austria.Competitions, sometimes referred to as dancesport, range from world championships, regulated by the World Dance Council (WDC), to less advanced dancers at various proficiency levels.", "Most competitions are divided into professional and amateur, though in the USA pro-am competitions typically accompany professional competitions.", "The International Olympic Committee now recognizes competitive ballroom dance.", "It has recognized another body, the World DanceSport Federation (WDSF), as the sole representative body for dancesport in the Olympic Games.Ballroom dance competitions are regulated by each country in its own way.", "There are about 30 countries which compete regularly in international competitions.", "There are another 20 or so countries which have membership of the WDC and/or the WDSF, but whose dancers rarely appear in international competitions.", "In Britain there is the British Dance Council, which grants national and regional championship titles, such as the British Ballroom Championships, the British Sequence Championships and the United Kingdom Championships.", "In the United States, the member branches of the WDC (National Dance Council of America) and the WDSF (USA Dance) both grant national and regional championship titles.Ballroom dancing competitions in the former USSR also included the Soviet Ballroom dances, or ''Soviet Programme''.", "Australian New Vogue is danced both competitively and socially.", "In competition, there are 15 recognized New Vogue dances, which are performed by the competitors in sequence.", "These dance forms are not recognized internationally, neither are the US variations such as American Smooth, and Rhythm.", "Such variations in dance and competition methods are attempts to meets perceived needs in the local market-place.Internationally, the Blackpool Dance Festival, hosted annually at Blackpool, England is considered the most prestigious event a dancesport competitor can attend.Formation dance is another style of competitive dance recognized by the WDSF.", "In this style, multiple dancers (usually in couples and typically up to 16 dancers at one time) compete on the same team, moving in and out of various formations while dancing.", "The Blackpool Dance Festival also holds an annual event for competitive formation dancing.=== Elements of competition ===MIT ballroom dance competition.", "A judge stands in the foreground.In competitive ballroom, dancers are judged by diverse criteria such as poise, the hold or frame, posture, musicality and expression, timing, body alignment and shape, floor craft, foot and leg action, and presentation.", "Judging in a performance-oriented sport is inevitably subjective in nature, and controversy and complaints by competitors over judging placements are not uncommon.", "The scorekeepers—called scrutineers—will tally the total number recalls accumulated by each couple through each round until the finals when the Skating system is used to place each couple by ordinals, typically 1–6, though the number of couples in the final may vary.", "Sometimes, up to 8 couples may be present on the floor during the finals.Competitors dance at different levels based on their ability and experience.", "The levels are split into two categories, syllabus and open.", "The syllabus levels are newcomer/pre-bronze, bronze, silver, and gold—with gold the highest syllabus level and newcomer the lowest.", "In these levels, moves are restricted to those written in a syllabus, and illegal moves can lead to disqualification.", "Each level, bronze, silver, and gold, has different moves on their syllabus, increasing in difficulty.", "There are three levels in the open category; novice, pre-champ, and champ in increasing order of skill.", "At those levels, dancers no longer have restrictions on their moves, so complex routines are more common.=== Medal evaluations ===Medal evaluations for amateurs enable dancers' individual abilities to be recognized according to conventional standards.", "In medal evaluations, which are run by bodies such as the Imperial Society of Teachers of Dancing (ISTD) and the United Kingdom Alliance (UKA), each dancer performs two or more dances in a certain genre in front of a judge.", "Genres such as Modern Ballroom or Latin are the most popular.", "Societies such as the ISTD and UKA also offer medal tests on other dance styles (such as Country & Western, Rock 'n Roll or Tap).", "In some North American examinations, levels include Newcomer, Bronze, Silver, Gold, Novice, Pre-championship, and Championship; each level may be further subdivided into either two or four separate sections." ], [ "Collegiate ballroom", "People on the dance floor waiting to dance and compete.There is a part of the ballroom world dedicated to college students.", "These chapters are typically clubs or teams that have an interest in ballroom dancing.", "Teams hold fundraisers, social events, and ballroom dance lessons.", "Ballroom dance teams' goals are to have fun and learn to dance well.", "There is a strong focus on finding a compatible dance partner and bonding with teammates.", "There is also a competitive side to collegiate ballroom - collegiate teams often hold competitions and invite other teams to participate.", "These competitions are often run with many of the same rules are regular amateur competitions as outlined above, but are usually organized entirely by collegiate teams.", "Examples include the MIT Open Ballroom Dance Competition, Big Apple Dancesport Challenge, Purdue Ballroom Classic, Cardinal Classic, Berkeley Classic, and Harvard Invitational." ], [ "Dances", "\"Ballroom dance\" refers most often to the ten dances of '''Standard''' and '''Latin''', though the term is also often used interchangeably with the five International Ballroom dances.", "Sequence dancing, which is danced predominantly in the United Kingdom, and its development New Vogue in Australia and New Zealand, are also sometimes included as a type of Ballroom dancing.In the United States and Canada, the '''American Style''' ('''American Smooth''' and '''American Rhythm''') also exists.", "The dance technique used for both International and American styles is similar, but International Ballroom allows only closed dance positions, whereas American Smooth allows closed, open and separated dance movements.", "In addition, different sets of dance figures are usually taught for the two styles.", "International Latin and American Rhythm have different styling, and have different dance figures in their respective syllabi.Other dances sometimes placed under the umbrella \"ballroom dance\" include nightclub dances such as Lindy Hop, West Coast swing, nightclub two step, hustle, salsa, and merengue.", "The categorization of dances as \"ballroom dances\" has always been fluid, with new dances or folk dances being added to or removed from the ballroom repertoire from time to time, so no list of subcategories or dances is any more than a description of current practices.", "There are other dances historically accepted as ballroom dances, and are revived via the vintage dance movement.In Europe, Latin Swing dances include Argentine tango, mambo, Lindy Hop, swing boogie (sometimes also known as nostalgic boogie), and discofox.", "One example of this is the subcategory of cajun dances that originated in Acadiana, with branches reaching both coasts of the United States.Standard/Smooth dances are normally danced to Western music (often from the mid-twentieth century), and couples dance counter-clockwise around a rectangular floor following the line of dance.", "In competitions, competitors are costumed as would be appropriate for a white tie affair, with full gowns for the ladies and bow tie and tail coats for the men; though in American Smooth it is now conventional for the men to abandon the tailsuit in favor of shorter tuxedos, vests, and other creative outfits.Latin/Rhythm dances are commonly danced to contemporary Latin American music and (in case of jive) Western music.", "With the exception of a few traveling dances like samba and pasodoble, couples do not follow the line of dance but perform their routines more or less in one spot.", "In competitions, the women are often dressed in short-skirted Latin outfits while the men are outfitted in tight-fitting shirts and pants, the goal being to emphasize the dancers' leg action and body movements." ], [ "Competitive dances", "tango in 2006.The couple, dancing for the US, came third in the Professional World Championship 2009.===Standard/Smooth======= Waltz ====Waltz began as a country folk dance in Austria and Bavaria in the 17th century.", "In the early 19th century it was introduced in England.", "It was the first dance where a man held a woman close to his body.", "When performing the dance, the upper body is kept to the left throughout all figures, the follower's body leans to the right side of the leader while the head is extended left to follow the elbow.", "Figures with rotation have little rise.", "The start of the rise begins slowly from the first count, peaks on the 2nd count and lowers slowly on the 3rd.", "Sway is also used on the second step to make the step longer and also to slow down the momentum by bringing the feet together.", "Waltz is performed for both International Standard and American Smooth.==== Viennese Waltz ====Viennese waltz originated in Provence area in France in 1559 and is recognized as the oldest of all ballroom dances.", "It was introduced in England as German waltz in 1812 and became popular throughout the 19th century by the music of Josef and Johann Strauss.", "It is often referred to as the classic “old-school” ballroom.", "Viennese Waltz music is quite fast.", "Slight shaping of the body moves towards the inside of the turn and shaping forward and up to lengthen the opposite side from direction.", "Reverse turn is used to travel down long side and is overturned.", "While natural turn is used to travel short side and is underturned to go around the corners.", "Viennese waltz is performed for both International Standard and American Smooth.==== Tango ====Tango originated in Buenos Aires in the late 19th century.", "Modern Argentine tango is danced in both open and closed embraces which focuses on the lead and follow moving in harmony of the tango's passionate charging music.", "The tango's technique is like walking to the music while keeping feet grounded and allowing ankles and knees to brush against one another during each step taken.", "Tango is a flat-footed dance and unlike the other dances, has no rise and fall.", "Body weight is kept over the toes and the connection is held between the dancers in the hips.Ballroom tango, however, is a dance with a far more open frame, often utilising strong and staccato movements.", "Ballroom tango, rather than Argentine tango, is performed in international competition.==== Foxtrot ====The foxtrot is an American dance, believed to be of African-American origin.", "It was named by a vaudeville performer Harry Fox in 1914.Fox was rapidly trotting step to ragtime music.", "The dance therefore was originally named as the “Fox’s trot”.", "The foxtrot can be danced at slow, medium, or fast tempos depending on the speed of the jazz or big band music.", "The partners are facing one another and frame rotates from one side to another, changing direction after a measure.", "The dance is generally danced flat, with not much rise and fall.", "The walking steps are taken as slow for the two beats per steps and quick for one beat per step.", "Foxtrot is performed for both International Standard and American Smooth.==== Quickstep ====The quickstep is an English dance and was invented in the 1920s as a combination of faster tempo of foxtrot and the Charleston.", "It is a fast moving dance, so men are allowed to close their feet and the couples move in short syncopated steps.", "Quickstep includes the walks, runs, chasses, and turns of the original foxtrot dance, with some other fast figures such as locks, hops, run, quick step, jump and skips.", "Quick step is performed as an International Standard dance.===Latin/Rhythm======= Pasodoble ====The pasodoble originated from Spain and its dramatic bullfights.", "The dance is mostly performed only in competitions and rarely socially because of its many choreographic rules.", "The lead plays the role of the matador while the follow takes the role of the matador's cape, the bull, or even the matador.", "The chasse cape refers to the lead using the follow to turn them as if they are the cape, and the appel is when the lead stomps their foot to get the bull's attention.", "Pasodoble is performed as an International Latin dance.==== Spanish bolero ====The Spanish bolero was developed in the late 18th century out of the ''seguidilla'', and its popularization is attributed to court dancers such as Sebastián Cerezo.", "It became one of the most popular ballroom dances of the 19th century and saw many classical adaptations.", "However, by the 20th century it had become old-fashioned.", "A Cuban music genre of the same name, bolero, which became popular in the early 20th century, is unrelated to the Spanish dance.====Cuban bolero====Although Cuban bolero was born as a form of ''trova'', traditional singer/songwriter tradition from eastern Cuba, with no associated dance, it soon became a ballroom favorite in Cuba and all of Latin America.", "The dance most commonly represents the couple falling in love.", "Modern bolero is seen as a combination of many dances: like a slow salsa with contra-body movement of tango, patterns of rhumba, and rise and fall technique and personality of waltz and foxtrot.", "Bolero can be danced in a closed hold or singly and then coming back together.", "It is performed as an American Rhythm dance.==== Samba ====Samba is the national dance of Brazil.", "The rhythm of samba and its name originated from the language and culture of West African slaves.", "In 1905, samba became known to other countries during an exhibition in Paris.", "In the 1940s, samba was introduced in America through Carmen Miranda.", "The international version of Ballroom Samba has been based on an early version of Brazilian Samba called Maxixe, but has since developed away and differs strongly from Brazilian Ballroom Samba, which is called Samba de Gafieira.", "International Ballroom Samba is danced with a slight bounce which is created through the bending and straightening the knee.", "It is performed as an International Latin dance, although most of its modern development has occurred outside Latin America.==== Rumba ====Rumba came to the United States from Cuba in the 1920s and became a popular cabaret dance during prohibition.", "Rumba is a ballroom adaptation of son cubano and bolero (the Cuban genre) and, despite its name, it rarely included elements of Cuban rumba.", "It includes Cuban motions through knee-strengthening, figure-eight hip rotation, and swiveling foot action.", "An important characteristic of rumba is the powerful and direct lead achieved through the ball of the foot.", "Rumba is performed for both International Latin and American Rhythm.==== Mambo ====Mambo was developed as an offshoot of danzón, the national dance of Cuba, in the late 1930s by Orestes López and his brother Cachao, of Arcaño y sus Maravillas.", "They conceived a new form of danzón influenced by son cubano, with a faster, improvised final section, which allowed dancers to more freely express themselves, given that danzón had traditionally a very rigid structure.", "In the 1940s, Dámaso Pérez Prado transformed the mambo from the charanga into the big band format, and took it to Mexico and the United States, where it became a \"dance craze\".==== Cha Cha ====Cha Cha (sometimes wrongly called Cha Cha Cha based on a \"street version\" of the dance with shifted timing) was developed by Enrique Jorrín in the early 1950s, as a slower alternative to Mambo—and, in fact, was originally called Triple Mambo.", "The Cha Cha is a flirtatious dance with many hip rotations and partners synchronising their movements.", "The dance includes bending and straightening of the knee giving it a touch of Cuban motion.", "Cha-cha is performed for both International Latin and American Rhythm.==== East Coast Swing ====Swing in 1927 was originally named the Lindy Hop named by Shorty George Snowden.", "There have been 40 different versions documented over the years; most common is the East Coast swing which is performed in the American Smooth (or American Rhythm) only in the U.S. or Canada.", "The East Coast swing was established by Arthur Murray and others only shortly after World War II.", "Swing music is very lively and upbeat and can be danced to jazz or big band music.", "The swing dancing style has much bounce and energy.", "Swing also includes many spins and underarm turns.", "East Coast swing is performed as an American Rhythm dance.==== Jive ====The jive is part of the swing dance group and is a very lively variation of the jitterbug.", "Jive originated from African American clubs in the early 1940s.", "During World War II, American soldiers introduced the jive in England where it was adapted to today's competitive jive.", "In jive, the man leads the dance while the woman encourages the man to ask her to dance.", "It is danced to big band music, and

States\" and \"the most reprehensibly racist film in Hollywood history\".", "The film has been denounced for its racist depiction of African Americans.", "The film portrays its black characters (many of whom are played by white actors in blackface) as unintelligent and sexually aggressive toward white women.", "The Ku Klux Klan (KKK) is portrayed as a heroic force, necessary to preserve American values, protect white women, and maintain white supremacy.Popular among white audiences nationwide upon its release, the film's success was both a consequence of and a contributor to racial segregation throughout the U.S.", "In response to the film's depictions of black people and Civil War history, African Americans across the U.S. organized and protested.", "In Boston and other localities, black leaders and the NAACP spearheaded an unsuccessful campaign to have it banned on the basis that it inflamed racial tensions and could incite violence.", "It was also denied release in Chicago, Ohio, Denver, Pittsburgh, St. Louis, and Minneapolis.", "Griffith's indignation at efforts to censor or ban the film motivated him to produce ''Intolerance'' the following year.In spite of

the two, making it an inland sea.", "The Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt.", "It includes the Gulf of Bothnia (divided into the Bothnian Bay and the Bothnian Sea), the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk.The \"Baltic Proper\" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula.The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German Bight of the North Sea via the Kiel Canal." ], [ "Definitions", "Hel PeninsulaDanish Straits and southwestern Baltic SeaÅland between Baltic Sea and the Gulf of Bothnia=== Administration ===The Helsinki Convention on the Protection of the Marine Environment of the Baltic Sea Area includes the Baltic Sea and the Kattegat, without calling Kattegat a part of the Baltic Sea, \"For the purposes of this Convention the 'Baltic Sea Area' shall be the Baltic Sea and the Entrance to the Baltic Sea, bounded by the parallel of the Skaw in the Skagerrak at 57°44.43'N.", "\"===Traffic history===Historically, the Kingdom of Denmark collected Sound Dues from ships at the border between the ocean and the land-locked Baltic Sea, in tandem: in the Øresund at Kronborg castle near Helsingør; in the Great Belt at Nyborg; and in the Little Belt at its narrowest part then Fredericia, after that stronghold was built.", "The narrowest part of Little Belt is the \"Middelfart Sund\" near Middelfart.===Oceanography===Geographers widely agree that the preferred physical border between the Baltic and North Seas is the Langelandsbælt (the southern part of the Great Belt strait near Langeland) and the Drogden-Sill strait.", "The Drogden Sill is situated north of Køge Bugt and connects Dragør in the south of Copenhagen to Malmö; it is used by the Øresund Bridge, including the ''Drogden Tunnel''.", "By this definition, the Danish Straits is part of the entrance, but the Bay of Mecklenburg and the Bay of Kiel are parts of the Baltic Sea.Another usual border is the line between Falsterbo, Sweden, and Stevns Klint, Denmark, as this is the southern border of Øresund.", "It is also the border between the shallow southern Øresund (with a typical depth of 5–10 meters only) and notably deeper water.===Hydrography and biology===Drogden Sill (depth of ) sets a limit to Øresund and Darss Sill (depth of ), and a limit to the Belt Sea.", "The shallow sills are obstacles to the flow of heavy salt water from the Kattegat into the basins around Bornholm and Gotland.The Kattegat and the southwestern Baltic Sea are well oxygenated and have a rich biology.", "The remainder of the Sea is brackish, poor in oxygen, and in species.", "Thus, statistically, the more of the entrance that is included in its definition, the healthier the Baltic appears; conversely, the more narrowly it is defined, the more endangered its biology appears." ], [ "Etymology and nomenclature", "Tacitus called it the Suebic Sea, Latin: ''Mare Suebicum'' after the Germanic people of the Suebi, and Ptolemy ''Sarmatian Ocean'' after the Sarmatians, but the first to name it the ''Baltic Sea'' () was the eleventh-century German chronicler Adam of Bremen.", "The origin of the latter name is speculative and it was adopted into Slavic and Finnic languages spoken around the sea, very likely due to the role of Medieval Latin in cartography.", "It might be connected to the Germanic word ''belt'', a name used for two of the Danish straits, the Belts, while others claim it to be directly derived from the source of the Germanic word, Latin ''balteus'' \"belt\".", "Adam of Bremen himself compared the sea with a belt, stating that it is so named because it stretches through the land as a belt (''Balticus, eo quod in modum baltei longo tractu per Scithicas regiones tendatur usque in Greciam'').He might also have been influenced by the name of a legendary island mentioned in the ''Natural History'' of Pliny the Elder.", "Pliny mentions an island named ''Baltia'' (or ''Balcia'') with reference to accounts of Pytheas and Xenophon.", "It is possible that Pliny refers to an island named Basilia (\"the royal\") in ''On the Ocean'' by Pytheas.", "''Baltia'' also might be derived from \"belt\", and therein mean \"near belt of sea, strait\".Others have suggested that the name of the island originates from the Proto-Indo-European root ''*bʰel'' meaning \"white, fair\", which may echo the naming of seas after colours relating to the cardinal points (as per Black Sea and Red Sea).", "This '*bʰel' root and basic meaning were retained in Lithuanian (as ''baltas''), Latvian (as ''balts'') and Slavic (as ''bely'').", "On this basis, a related hypothesis holds that the name originated from this Indo-European root via a Baltic language such as Lithuanian.", "Another explanation is that, while derived from the aforementioned root, the name of the sea is related to names for various forms of water and related substances in several European languages, that might have been originally associated with colors found in swamps (compare Proto-Slavic ''*bolto'' \"swamp\").", "Yet another explanation is that the name originally meant \"enclosed sea, bay\" as opposed to open sea.In the Middle Ages the sea was known by a variety of names.", "The name Baltic Sea became dominant only after 1600.Usage of ''Baltic'' and similar terms to denote the region east of the sea started only in the 19th century.===Name in other languages===The Baltic Sea was known in ancient Latin language sources as ''Mare Suebicum'' or even ''Mare Germanicum''.", "Older native names in languages that used to be spoken on the shores of the sea or near it usually indicate the geographical location of the sea (in Germanic languages), or its size in relation to smaller gulfs (in Old Latvian), or tribes associated with it (in Old Russian the sea was known as the Varanghian Sea).", "In modern languages, it is known by the equivalents of \"East Sea\", \"West Sea\", or \"Baltic Sea\" in different languages:* '''\"Baltic Sea\"''' is used in Modern English; in the Baltic languages Latvian (''Baltijas jūra''; in Old Latvian it was referred to as \"the Big Sea\", while the present day Gulf of Riga was referred to as \"the Little Sea\") and Lithuanian (''Baltijos jūra''); in Latin (''Mare Balticum'') and the

Swedish (''Östersjön'').", "In Old English it was known as ''Ostsǣ''; also in Hungarian the former name was ''Keleti-tenger'' (\"East-sea\", due to German influence).", "In addition, Finnish, a Finnic language, uses the term ''Itämeri'' \"East Sea\", possibly a calque from a Germanic language.", "As the Baltic is not particularly eastward in relation to Finland, the use of this term may be a leftover from the period of Swedish rule.", "* In another Finnic language, Estonian, it is called the '''\"West Sea\"''' (''Läänemeri''), with the correct geography (the sea is west of Estonia).", "In South Estonian, it has the meaning of both '''\"West Sea\"''' and '''\"Evening Sea\"''' (''Õdagumeri'').", "In the endangered Livonian language of Latvia, the sea (and sometimes the Irbe Strait as well) is called the '''\"Large Sea\"''' (''Sūŗ meŗ'' or ''Sūr meŗ'')." ], [ "History", "===Classical world===At the time of the Roman Empire, the Baltic Sea was known as the ''Mare Suebicum'' or

and chunks floated about.", "The Suebi eventually migrated southwest to temporarily reside in the Rhineland area of modern Germany, where their name survives in the historic region known as Swabia.", "Jordanes called it the ''Germanic Sea'' in his work, the ''Getica''.===Middle Ages===Cape Arkona on the island of Rügen in Germany, was a sacred site of the Rani tribe before Christianization.In the early Middle Ages, Norse (Scandinavian) merchants built a trade empire all around the Baltic.", "Later, the Norse fought for control of the Baltic against Wendish tribes dwelling on the southern shore.", "The Norse also used the rivers of Russia for trade routes, finding their way eventually to the Black Sea and southern Russia.", "This Norse-dominated period is referred to as the Viking Age.Since the Viking Age, the Scandinavians have referred to the Baltic Sea as ''Austmarr'' (\"Eastern Lake\").", "\"Eastern Sea\", appears in the ''Heimskringla'' and ''Eystra salt'' appears in ''Sörla þáttr''.", "Saxo Grammaticus recorded in ''Gesta Danorum'' an older name, ''Gandvik'', ''-vik'' being Old Norse for \"bay\", which implies that the Vikings correctly regarded it as an inlet of the sea.", "Another form of the name, \"Grandvik\", attested in at least one English translation of ''Gesta Danorum'', is likely to be a misspelling.In addition to fish the sea also provides amber, especially from its southern shores within today's borders of Poland, Russia and Lithuania.", "First mentions of amber deposits on the South Coast of the Baltic Sea date back to the 12th century.", "The bordering countries have also traditionally exported lumber, wood tar, flax, hemp and furs by ship across the Baltic.", "Sweden had from early medieval times exported iron and silver mined there, while Poland had and still has extensive salt mines.", "Thus, the Baltic Sea has long been crossed by much merchant shipping.The lands on the Baltic's eastern shore were among the last in Europe to be

and Germans (Livonian Brothers of the Sword).", "The Teutonic Order gained control over parts of the southern and eastern shore of the Baltic Sea, where they set up their monastic state.", "Lithuania was the last European state to convert to Christianity.===An arena of conflict===Main trading routes of the Hanseatic League (''Hanse'').In the period between the 8th and 14th centuries, there was much piracy in the Baltic from the coasts of Pomerania and Prussia, and the Victual Brothers held Gotland.Starting in the 11th century, the southern and eastern shores of the Baltic were settled by

new capital, Saint Petersburg, at the mouth of the Neva river at the east end of the Gulf of Finland.", "There was much trading not just within the Baltic region but also with the North Sea region, especially eastern England and the Netherlands: their fleets needed the Baltic timber, tar, flax, and hemp.During the Crimean War, a joint British and French fleet attacked the Russian fortresses in the Baltic; the case is also known as the Åland War.", "They bombarded Sveaborg, which guards Helsinki; and Kronstadt, which guards Saint Petersburg; and they destroyed Bomarsund in Åland.", "After the unification of Germany in 1871, the whole southern coast became German.", "World War I was partly fought in the Baltic Sea.", "After 1920 Poland was granted access to the Baltic Sea at the expense

the peak of the winter and rises to during the peak of the summer, with an annual average of around .", "A similar pattern can be seen in the Gotland Basin, which is located between the island of Gotland and Latvia.", "In the deep of these basins the temperature variations are smaller.", "At the bottom of the Bornholm Basin, deeper than , the temperature typically is , and at the bottom of the Gotland Basin, at depths greater than , the temperature typically is .", "Generally, offshore locations, lower latitudes and islands maintain maritime climates, but adjacent to the water continental climates are common, especially on the Gulf of Finland.", "In the northern tributaries the climates transition from moderate continental to subarctic on the northernmost coastlines.On the long-term average, the Baltic Sea is ice-covered at the annual maximum for about 45% of its surface area.", "The ice-covered area during such a typical winter includes the Gulf of Bothnia, the Gulf of Finland, the Gulf of Riga, the archipelago west of Estonia, the Stockholm archipelago, and the Archipelago Sea southwest of Finland.", "The remainder of the Baltic does not freeze during a normal winter, except sheltered bays and shallow lagoons such as the Curonian Lagoon.", "The ice reaches its maximum extent in February or March; typical ice thickness in the northernmost areas in the Bothnian Bay,

Gulf of Riga freeze typically in late January.", "In 2011, the Gulf of Finland was completely frozen on 15 February.The ice extent depends on whether the winter is mild, moderate, or severe.", "In severe winters ice can form around southern Sweden and even in the Danish straits.", "According to the 18th-century natural historian William Derham, during the severe winters of 1703 and 1708, the ice cover reached as far as the Danish straits.", "Frequently, parts of the Gulf of Bothnia and the Gulf of Finland are frozen, in addition to coastal fringes in more southerly locations such as the Gulf of Riga.", "This description meant that the whole of the Baltic Sea was covered with ice.Since 1720, the Baltic Sea has frozen over entirely 20 times, most recently in early 1987, which was the most severe winter in Scandinavia since 1720.The ice then covered .", "During the winter of 2010–11, which was quite severe compared to those of the last decades, the maximum ice cover was , which was reached on 25 February 2011.The ice then extended from the north down to the northern tip of Gotland, with small ice-free areas on either side, and the east coast of the Baltic Sea was covered by an ice sheet about wide all the way to Gdańsk.", "This was brought about by a stagnant high-pressure area that lingered over central and northern Scandinavia from around 10 to 24 February.", "After this, strong southern winds pushed the ice further into the north, and much of the waters north of Gotland were again free of ice, which had then packed against the shores of southern Finland.", "The effects of the afore-mentioned high-pressure area did not reach the southern parts of the Baltic Sea, and thus the entire sea did not freeze over.", "However, floating ice was additionally observed near Świnoujście harbor in January 2010.In recent years before 2011, the Bothnian Bay and the Bothnian Sea were frozen with solid ice near the Baltic coast and dense floating ice far from it.", "In 2008, almost no ice formed except for a short period in March.Piles of drift ice on the shore of Puhtulaid, near Virtsu, Estonia, in late AprilDuring winter, fast ice, which is attached to the shoreline, develops first, rendering ports unusable without the services of icebreakers.", "Level ice, ice sludge, pancake ice, and rafter ice form in the more open regions.", "The gleaming expanse of ice is similar to the Arctic, with wind-driven pack ice and ridges up to .", "Offshore of the landfast ice, the ice remains very dynamic all year, and it is relatively easily moved around by winds and therefore forms pack ice, made up of large piles and ridges pushed against the landfast ice and shores.In spring, the Gulf of Finland and the Gulf of Bothnia normally thaw in late April, with some ice ridges persisting until May in the eastern extremities of the Gulf of Finland.", "In the northernmost reaches of the Bothnian Bay, ice usually stays until late May; by early June it is practically always gone.", "However, in the famine year of 1867 remnants of ice were observed as late as 17 July near Uddskär.", "Even as far south as Øresund, remnants of ice have been observed in May on several occasions; near Taarbaek on 15 May 1942 and near Copenhagen on 11 May 1771.Drift ice was also observed on 11 May 1799.The ice cover is the main habitat for two large mammals, the grey seal (''Halichoerus grypus'') and the Baltic ringed seal (''Pusa hispida botnica''), both of which feed underneath the ice and breed on its surface.", "Of these two seals, only the Baltic ringed seal suffers when there is not adequate ice in the Baltic Sea, as it feeds its young only while on ice.", "The grey seal is adapted to reproducing also with no ice in the sea.", "The sea ice also harbors several species of algae that live in the bottom and inside unfrozen brine pockets in the ice.Due to the often fluctuating winter temperatures between above and below freezing, the saltwater ice of the Baltic Sea can be treacherous and hazardous to walk on, in particular in comparison to the more stable fresh water-ice sheets in the interior lakes.===Hydrography===Depths of the Baltic Sea in metersThe Baltic Sea flows out through the Danish straits; however, the flow is complex.", "A surface layer of brackish water discharges per year into the North Sea.", "Due to the difference in salinity, by salinity permeation principle, a sub-surface layer of more saline water moving in the opposite direction brings in per year.", "It mixes very slowly with the upper waters, resulting in a salinity gradient from top to bottom, with most of the saltwater remaining below deep.", "The general circulation is anti-clockwise: northwards along its eastern boundary, and south along with the western one .The difference between the outflow and the inflow comes entirely from fresh water.", "More than 250 streams drain a basin of about , contributing a volume of per year to the Baltic.", "They include the major rivers of north Europe, such as the Oder, the Vistula, the Neman, the Daugava and the Neva.", "Additional fresh water comes from the difference of precipitation less evaporation, which is positive.An important source of salty water is infrequent inflows (also known as major Baltic inflows or MBIs) of North Sea water into the Baltic.", "Such inflows, important to the Baltic ecosystem because of the oxygen they transport into the Baltic deeps, happen on average once per year, but large pulses that can replace the anoxic deep water in the Gotland Deep occur about once in ten years.", "Previously, it was believed that the frequency of MBIs had declined since 1980, but recent studies have challenged this view and no longer display a clear change in the frequency or intensity of saline inflows.", "Instead, a decadal variability in the intensities of MBIs is observed with a main period of approximately 30 years.The water level is generally far more dependent on the regional wind situation than on tidal effects.", "However, tidal currents occur in narrow passages in the western parts of the Baltic Sea.", "Tides can reach in the Gulf of Finland.The significant wave height is generally much lower than that of the North Sea.", "Quite violent, sudden storms sweep the surface ten or more times a year, due to large transient temperature differences and a long reach of the wind.", "Seasonal winds also cause small changes in sea level, of the order of .", "According to the media, during a storm in January 2017, an extreme wave above has been measured and significant wave height of around has been measured by the FMI.", "A numerical study has shown the presence of events with significant wave heights.", "Those extreme waves events can play an important role in the coastal zone on erosion and sea dynamics.===Salinity===Baltic Sea near Klaipėda (Karklė).The Baltic Sea is the world's largest inland brackish sea.", "Only two other brackish waters are larger according to some measurements: The Black Sea is larger in both surface area and water volume, but most of it is located outside the continental shelf (only a small fraction is inland).", "The Caspian Sea is larger in water volume, but—despite its name—it is a lake rather than a sea.The Baltic Sea's salinity is much lower than that of ocean water (which averages 3.5%), as a result of abundant freshwater runoff from the surrounding land (rivers, streams and alike), combined with the shallowness of the sea itself; runoff contributes roughly one-fortieth its total volume per year, as the volume of the basin is about and yearly runoff is about .The open surface waters of the Baltic Sea \"proper\" generally have a salinity of 0.3 to 0.9%, which is border-line freshwater.", "The flow of freshwater into the sea from approximately two hundred rivers and the introduction of salt from the southwest builds up a gradient of salinity in the Baltic Sea.", "The highest surface salinities, generally 0.7–0.9%, are in the southwesternmost part of the Baltic, in the Arkona and Bornholm basins (the former located roughly between southeast Zealand and Bornholm, and the latter directly east of Bornholm).", "It gradually falls further east and north, reaching the lowest in the Bothnian Bay at around 0.3%.", "Drinking the surface water of the Baltic as a means of survival would actually hydrate the body instead of dehydrating, as is the case with ocean water.As saltwater is denser than freshwater, the bottom of the Baltic Sea is saltier than the surface.", "This creates a vertical stratification of the water column, a halocline, that represents a barrier to the exchange of oxygen and nutrients, and fosters completely separate maritime environments.", "The difference between the bottom and surface salinities varies depending on location.", "Overall it follows the same southwest to east and north pattern as the surface.", "At the bottom of the Arkona Basin (equalling depths greater than ) and Bornholm Basin (depths greater than ) it is typically 1.4–1.8%.", "Further east and north the salinity at the bottom is consistently lower, being the lowest in Bothnian Bay (depths greater than ) where it is slightly below 0.4%, or only marginally higher than the surface in the same region.In contrast, the salinity of the Danish straits, which connect the Baltic Sea and Kattegat, tends to be significantly higher, but with major variations from year to year.", "For example, the surface and bottom salinity in the Great Belt is typically around 2.0% and 2.8% respectively, which is only somewhat below that of the Kattegat.", "The water surplus caused by the continuous inflow of rivers and streams to the Baltic Sea means that there generally is a flow of brackish water out through the Danish Straits to the Kattegat (and eventually the Atlantic).", "Significant flows in the opposite direction, salt water from the Kattegat through the Danish Straits to the Baltic Sea, are less regular and are known as major Baltic inflows (MBIs).=== Major tributaries ===The rating of mean discharges differs from the ranking of hydrological

example, the common starfish and shore crab, two species that are very widespread along European coasts, are both unable to cope with the significantly lower salinity.", "Their range limit is west of Bornholm, meaning that they are absent from the vast majority of the Baltic Sea.", "Some marine species, like the Atlantic cod and European flounder, can survive at relatively low salinities but need higher salinities to breed, which therefore occurs in deeper parts of the Baltic Sea.", "The common blue mussel is the dominating animal species, and makes up more than 90% of the total animal biomass

more than 600 species of invertebrates, fish, aquatic mammals, aquatic birds and macrophytes, the Arkona Basin (roughly between southeast Zealand and Bornholm) is far richer than other more eastern and northern basins in the Baltic Sea, which all have less than 400 species from these groups, with the exception of the Gulf of Finland with more than 750 species.", "However, even the most diverse sections of the Baltic Sea have far fewer species than the almost-full saltwater Kattegat, which is home to more than 1600 species from these groups.", "The lack of tides has affected the marine species as compared with the Atlantic.Since the Baltic Sea is so young there are only two or three known endemic species: the brown alga ''Fucus radicans'' and the flounder ''Platichthys solemdali''.", "Both appear to have evolved in the Baltic basin and were only recognized as species in 2005 and 2018 respectively, having formerly been confused with more widespread relatives.", "The tiny Copenhagen cockle (''Parvicardium hauniense''), a rare mussel, is sometimes considered endemic, but has now been recorded in the Mediterranean.", "However, some consider non-Baltic records to be misidentifications of juvenile lagoon cockles (''Cerastoderma glaucum'').", "Several widespread marine species have distinctive subpopulations in the Baltic Sea adapted to the low salinity, such as the Baltic Sea forms of the Atlantic herring and lumpsucker, which are smaller than the widespread forms in the North Atlantic.A peculiar feature of the fauna is that it contains a number of glacial relict species, isolated populations of arctic species which have remained in the Baltic Sea since the last glaciation, such as the large isopod ''Saduria entomon'', the Baltic subspecies of ringed seal, and the fourhorn sculpin.", "Some of these relicts are derived from glacial lakes, such as ''Monoporeia affinis'', which is a main element in the benthic fauna of the low-salinity Bothnian

exacerbated the problem and led to increased eutrophication.Approximately of the Baltic's seafloor (a quarter of its total area) is a variable dead zone.", "The more saline (and therefore denser) water remains on the bottom, isolating it from surface waters and the atmosphere.", "This leads to decreased oxygen concentrations within the zone.", "It is mainly bacteria that grow in it, digesting organic material and releasing hydrogen sulfide.", "Because of this large anaerobic zone, the seafloor ecology differs from that of the neighboring Atlantic.Plans to artificially oxygenate areas of the Baltic that have experienced eutrophication have been proposed by the University of Gothenburg and Inocean AB.", "The proposal intends to use wind-driven pumps to inject oxygen (air) into waters

[ [ "Brackish water" ], [ "Introduction", "'''Brackish water''', sometimes termed '''brack water''', is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater.", "It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers.", "The word comes from the Middle Dutch root ''brak''.", "Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming.", "Brackish water is also the primary waste product of the salinity gradient power process.", "Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms).Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gravity of between 1.0004 and 1.0226.Thus, ''brackish'' covers a range of salinity regimes and is not considered a precisely defined condition.", "It is characteristic of many brackish surface waters that their salinity can vary considerably over space or time.", "Water with a salt concentration greater than 30‰ is considered saline.", "See the salinity table from the Wikipedia salinity article." ], [ "Brackish water habitats", "=== Estuaries ===Monodactylus argenteus''Brackish water condition commonly occurs when fresh water meets seawater.", "In fact, the most extensive brackish water habitats worldwide are estuaries, where a river meets the sea.The River Thames flowing through London is a classic river estuary.", "The town of Teddington a few miles west of London marks the boundary between the tidal and non-tidal parts of the Thames, although it is still considered a freshwater river about as far east as Battersea insofar as the average salinity is very low and the fish fauna consists predominantly of freshwater species such as roach, dace, carp, perch, and pike.", "The Thames Estuary becomes brackish between Battersea and Gravesend, and the diversity of freshwater fish species present is smaller, primarily roach and dace; euryhaline marine species such as flounder, European seabass, mullet, and smelt become much more common.", "Further east, the salinity increases and the freshwater fish species are completely replaced by euryhaline marine ones, until the river reaches Gravesend, at which point conditions become fully marine and the fish fauna resembles that of the adjacent North Sea and includes both euryhaline and stenohaline marine species.", "A similar pattern of replacement can be observed with the aquatic plants and invertebrates living in the river.This type of ecological succession from freshwater to marine ecosystem is typical of river estuaries.", "River estuaries form important staging points during the migration of anadromous and catadromous fish species, such as salmon, shad and eels, giving them time to form social groups and to adjust to the changes in salinity.", "Salmon are anadromous, meaning they live in the sea but ascend rivers to spawn; eels are catadromous, living in rivers and streams, but returning to the sea to breed.", "Besides the species that migrate through estuaries, there are many other fish that use them as \"nursery grounds\" for spawning or as places young fish can feed and grow before moving elsewhere.", "Herring and plaice are two commercially important species that use the Thames Estuary for this purpose.Estuaries are also commonly used as fishing grounds and as places for fish farming or ranching.", "For example, Atlantic salmon farms are often located in estuaries, although this has caused controversy, because in doing so, fish farmers expose migrating wild fish to large numbers of external parasites such as sea lice that escape from the pens the farmed fish are kept in.=== Mangroves ===Another important brackish water habitat is the mangrove swamp or '''mangal'''.", "Many, though not all, mangrove swamps fringe estuaries and lagoons where the salinity changes with each tide.", "Among the most specialised residents of mangrove forests are mudskippers, fish that forage for food on land, and archer fish, perch-like fish that \"spit\" at insects and other small animals living in the trees, knocking them into the water where they can be eaten.", "Like estuaries, mangrove swamps are extremely important breeding grounds for many fish, with species such as snappers, halfbeaks, and tarpon spawning or maturing among them.", "Besides fish, numerous other animals use mangroves, including such species as the saltwater crocodile, American crocodile, proboscis monkey, diamondback terrapin, and the crab-eating frog, ''Fejervarya cancrivora'' (formerly ''Rana cancrivora'').", "Mangroves represent important nesting sites for numerous birds groups such as herons, storks, spoonbills, ibises, kingfishers, shorebirds and seabirds.Although often plagued with mosquitoes and other insects that make them unpleasant for humans, mangrove swamps are very important buffer zones between land and sea, and are a natural defense against hurricane and tsunami damage in particular.The Sundarbans and Bhitarkanika Mangroves are two of the large mangrove forests in the world, both on the coast of the Bay of Bengal.=== Brackish seas and lakes ===Some seas and lakes are brackish.", "The Baltic Sea is a brackish sea adjoining the North Sea.", "Originally the Eridanos river system prior to the Pleistocene, since then it has been flooded by the North Sea but still receives so much freshwater from the adjacent lands that the water is brackish.", "As seawater is denser, the water in the Baltic is stratified, with seawater at the bottom and freshwater at the top.", "Limited mixing occurs because of the lack of tides and storms, with the result that the fish fauna at the surface is freshwater in composition while that lower down is more marine.", "Cod are an example of a species only found in deep water in the Baltic, while pike are confined to the less saline surface waters.The Caspian Sea is the world's largest lake and contains brackish water with a salinity about one-third that of normal seawater.", "The Caspian is famous for its peculiar animal fauna, including one of the few non-marine seals (the Caspian seal) and the great sturgeons, a major source of caviar.Hudson Bay is a brackish marginal sea of the Arctic ocean, it remains brackish due its limited connections to the open ocean, very high levels freshwater surface runoff input from the large Hudson Bay drainage basin, and low rate of evaporation due to being completely covered in ice for over half the year.In the Black Sea the surface water is brackish with an average salinity of about 17–18 parts per thousand compared to 30 to 40 for the oceans.", "The deep, anoxic water of the Black Sea originates from warm, salty water of the Mediterranean.Lake Texoma, a reservoir on the border between the U.S. states of Texas and Oklahoma, is a rare example of a brackish lake that is neither part of an endorheic basin nor a direct arm of the ocean, though its salinity is considerably lower than that of the other bodies of water mentioned here.", "The reservoir was created by the damming of the Red River of the South, which (along with several of its tributaries) receives large amounts of salt from natural seepage from buried deposits in the upstream region.", "The salinity is high enough that striped bass, a fish normally found only in salt water, has self-sustaining populations in the lake.=== Brackish marsh ====== Other brackish bodies of water===*" ], [ "Human uses", "Brackish water is being used by humans in many different sectors.", "It is commonly used as cooling water for

Andersson, former Commissioner of New York City's Department of Records, who helped organize a 375th Anniversary celebration in Bronck's hometown in 2014.===Use of definite article===The Bronx is referred to with the definite article as \"the Bronx\" or \"The Bronx\", both legally and colloquially.", "The \"County of the Bronx\" also takes \"the\" immediately before \"Bronx\" in formal references, like the coextensive \"Borough of the Bronx\".", "The United States Postal Service uses \"Bronx, NY\" for mailing addresses.", "The region was apparently named after the Bronx River and first appeared in the \"Annexed District of The Bronx\", created in 1874 out of part of Westchester County.", "It was continued in the \"Borough of The Bronx\", created in 1898, which included a larger annexation from Westchester County in 1895.The use of the definite article is attributed to the style of referring to rivers.", "A time-worn story purportedly explaining the use of the definite article in the borough's name says it stems from the phrase \"visiting the Broncks\", referring to the settler's family.The capitalization of the borough's name is sometimes disputed.", "Generally, the definite article is lowercase in place names (\"the Bronx\") except in some official references.", "The definite article is capitalized (\"The Bronx\") at the beginning of a sentence or in any other situation when a normally lowercase word would be capitalized.", "However, some people and groups refer to the borough with a capital letter at all times, such as Bronx Borough Historian Lloyd Ultan, The Bronx County Historical Society, and the Bronx-based organization Great and Glorious Grand Army of The Bronx, arguing the definite article is part of the proper name.", "In particular, the Great and Glorious Grand Army of The Bronx is leading efforts to make the city refer to the borough with an uppercase definite article in all uses, comparing the lowercase article in the Bronx's name to \"not capitalizing the 's' in 'Staten Island." ], [ "History", "link=File:History_of_Bronx_borough,_city_of_New_York;_(IA_historyofbronxbo00comf).pdf%3Fpage=9European colonization of the Bronx began in 1639.The Bronx was originally part of Westchester County, but it was ceded to New York County in two major parts (West Bronx, 1874 and East Bronx, 1895) before it became Bronx County.", "Originally, the area was part of the Lenape's Lenapehoking territory inhabited by Siwanoy of the Wappinger Confederacy.", "Over time, European colonists converted the borough into farmlands.===Before 1914===The Bronx's development is directly connected to its strategic location between New England and New York (Manhattan).", "Control over the bridges across the Harlem River plagued the period of British colonial rule.", "The King's Bridge, built in 1693 where Broadway reached the Spuyten Duyvil Creek, was a possession of Frederick Philipse, lord of Philipse Manor.", "Local farmers on both sides of the creek resented the tolls, and in 1759, Jacobus Dyckman and Benjamin Palmer led them in building a free bridge across the Harlem River.", "After the American Revolutionary War, the King's Bridge toll was abolished.The territory now contained within Bronx County was originally part of Westchester County, one of the 12 original counties of the English Province of New York.", "The present Bronx County was contained in the town of Westchester and parts of the towns in Yonkers, Eastchester, and Pelham.", "In 1846, a new town was created by division of Westchester, called West Farms.", "The town of Morrisania was created, in turn, from West Farms in 1855.In 1873, the town of Kingsbridge was established within the former borders of the town of Yonkers, roughly corresponding to the modern Bronx neighborhoods of Kingsbridge, Riverdale, and Woodlawn Heights, and included Woodlawn Cemetery.Among famous settlers in the Bronx during the 19th and early 20th centuries were author Willa Cather, tobacco merchant Pierre Lorillard, and inventor Jordan L. Mott, who established Mott Haven to house the workers at his iron works.The consolidation of the Bronx into New York City proceeded in two stages.", "In 1873, the state legislature annexed Kingsbridge, West Farms, and Morrisania to New York, effective in 1874; the three towns were soon abolished in the process.The whole territory east of the Bronx River was annexed to the city in 1895, three years before New York's consolidation with Brooklyn, Queens, and Staten Island.", "This included the Town of Westchester (which had voted against consolidation in 1894) and parts of Eastchester and Pelham.", "The nautical community of City Island voted to join the city in 1896.Following these two annexations, the Bronx's territory had moved from Westchester County into New York County, which already included Manhattan and the rest of pre-1874 New York City.On January 1, 1898, the consolidated City of New York was born, including the Bronx as one of the five distinct boroughs.", "However, it remained part of New York County until Bronx County was created in 1914.On April 19, 1912, those parts of New York County which had been annexed from Westchester County in previous decades were newly constituted as Bronx County, the 62nd and last county to be created by the state, effective in 1914.Bronx County's courts opened for business on January 2, 1914 (the same day that John P. Mitchel started work as Mayor of New York City).", "Marble Hill, Manhattan, was now connected to the Bronx by filling in the former waterway, but it is not part of the borough or county.===After 1914===The history of the Bronx during the 20th century may be divided into four periods: a boom period during 1900–1929, with a population growth by a factor of six from 200,000 in 1900 to 1.3 million in 1930.The Great Depression and post World War II years saw a slowing of growth leading into an eventual decline.", "The mid to late century were hard times, as the Bronx changed during 1950–1985 from a predominantly moderate-income to a predominantly lower-income area with high rates of violent crime and poverty in some areas.", "The Bronx has experienced an economic and developmental resurgence starting in the late 1980s that continues into today.====New York City expands====Grand Concourse and 161st Street as they appeared around 1900Simpson Street elevated station was built in 1904 and opened on November 26, 1904.It was listed in the National Register of Historic Places on September 17, 2004.The Bronx was a mostly rural area for many generations, with small farms supplying the city markets.", "In the late 19th century, however, it grew into a railroad suburb.", "Faster transportation enabled rapid population growth in the late 19th century, involving the move from horse-drawn street cars to elevated railways and the subway system, which linked to Manhattan in 1904.The South Bronx was a manufacturing center for many years and was noted as a center of piano manufacturing in the early part of the 20th century.", "In 1919, the Bronx was the site of 63 piano factories employing more than 5,000 workers.At the end of World War I, the Bronx hosted the rather small 1918 World's Fair at 177th Street and DeVoe Avenue.The Bronx underwent rapid urban growth after World War I. Extensions of the New York City Subway contributed to the increase in population as thousands of immigrants came to the Bronx, resulting in a major boom in residential construction.", "Among these groups, many Irish Americans, Italian Americans, and especially Jewish Americans settled here.", "In addition, French, German, Polish, and other immigrants moved into the borough.", "As evidence of the change in population, by 1937, 592,185 Jews lived in the Bronx (43.9% of the borough's population), while only 54,000 Jews lived in the borough in 2011.Many synagogues still stand in the Bronx, but most have been converted to other uses.====Change====Bootleggers and gangs were active in the Bronx during Prohibition (1920–1933).", "Irish, Italian, Jewish, and Polish gangs smuggled in most of the illegal whiskey, and the oldest sections of the borough became poverty-stricken.", "Police Commissioner Richard Enright said that speakeasies provided a place for \"the vicious elements, bootleggers, gamblers and their friends in all walks of life\" to cooperate and to \"evade the law, escape punishment for their crimes, and to deter the police from doing their duty\".Between 1930 and 1960, moderate and upper income Bronxites (predominantly non-Hispanic Whites) began to relocate from the borough's southwestern neighborhoods.", "This migration has left a mostly poor African American and Hispanic (largely Puerto Rican) population in the West Bronx.", "One significant factor that shifted the racial and economic demographics was the construction of Co-op City, built to house middle-class residents in family-sized apartments.", "The high-rise complex played a significant role in draining middle-class residents from older tenement buildings in the borough's southern and western fringes.", "Most predominantly non-Hispanic White communities today are in the eastern and northwestern sections of the borough.From the mid-1960s to the early 1980s, the quality of life changed for some Bronx residents.", "Historians and social scientists have suggested many factors, including the theory that Robert Moses' Cross Bronx Expressway destroyed existing residential neighborhoods and created instant slums, as put forward in Robert Caro's biography ''The Power Broker''.", "Another factor in the Bronx's decline may have been the development of high-rise housing projects, particularly in the South Bronx.", "Yet another factor may have been a reduction in the real estate listings and property-related financial services offered in some areas of the Bronx, such as mortgage loans or insurance policies—a process known as redlining.", "Others have suggested a \"planned shrinkage\" of municipal services, such as fire-fighting.", "There was also much debate as to whether rent control laws had made it less profitable (or more costly) for landlords to maintain existing buildings with their existing tenants than to abandon or destroy those buildings.In the 1970s, parts of the Bronx were plagued by a wave of arson.", "The burning of buildings was predominantly in the poorest communities, such as the South Bronx.", "One explanation of this event was that landlords decided to burn their low property-value buildings and take the insurance money, as it was easier for them to get insurance money than to try to refurbish a dilapidated building or sell a building in a severely distressed area.", "The Bronx became identified with a high rate of poverty and unemployment, which was mainly a persistent problem in the South Bronx.", "There were cases where tenants set fire to the building they lived in so they could qualify for emergency relocations by city social service agencies to better residences, sometimes being relocated to other parts of the city.Out of 289 census tracts in the Bronx borough, 7 tracts lost more than 97% of their buildings to arson and abandonment between 1970 and 1980; another 44 tracts had more than 50% of their buildings meet the same fate.", "By the early 1980s, the Bronx was considered the most blighted urban area in the country, particularly the South Bronx which experienced a loss of 60% of the population and 40% of housing units.", "However, starting in the 1990s, many of the burned-out and run-down tenements were replaced by new housing units.In May 1984, New York Supreme Court justice Peter J. McQuillan ruled that Marble Hill, Manhattan, was simultaneously part of the Borough of Manhattan (not the Borough of the Bronx) and part of Bronx County (not New York County) and the matter was definitively settled later that year when the New York Legislature overwhelmingly passed legislation declaring the neighborhood part of both New York County and the Borough of Manhattan and made this clarification retroactive to 1938, as reflected on the official maps of the city.===Revitalization===alt=four-story houses along a city streetSince the late 1980s, significant development has occurred in the Bronx, first stimulated by the city's \"Ten-Year Housing Plan\" and community members working to rebuild the social, economic and environmental infrastructure by creating affordable housing.", "Groups affiliated with churches in the South Bronx erected the Nehemiah Homes with about 1,000 units.", "The grass roots organization Nos Quedamos' endeavor known as Melrose Commons began to rebuild areas in the South Bronx.", "The IRT White Plains Road Line () began to show an increase in riders.", "Chains such as Marshalls, Staples, and Target opened stores in the Bronx.", "More bank branches opened in the Bronx as a whole (rising from 106 in 1997 to 149 in 2007), although not primarily in poor or minority neighborhoods, while the Bronx still has fewer branches per person than other boroughs.thumbIn 1997, the Bronx was designated an ''All America City'' by the National Civic League, acknowledging its comeback from the decline of the mid-century.", "In 2006, ''The New York Times'' reported that \"construction cranes have become the borough's new visual metaphor, replacing the window decals of the 1980s in which pictures of potted plants and drawn curtains were placed in the windows of abandoned buildings.\"", "The borough has experienced substantial new building construction since 2002.Between 2002 and June 2007, 33,687 new units of housing were built or were under way and $4.8 billion has been invested in new housing.", "In the first six months of 2007 alone total investment in new residential development was $965 million and 5,187 residential units were scheduled to be completed.", "Much of the new development is springing up in formerly vacant lots across the South Bronx.In addition there came a revitalization of the existing housing market in areas such as Hunts Point, the Lower Concourse, and the neighborhoods surrounding the Third Avenue Bridge as people buy apartments and renovate them.", "Several boutique and chain hotels opened in the 2010s in the South Bronx.New developments are underway.", "The Bronx General Post Office on the corner of the Grand Concourse and East 149th Street is being converted into a market place, boutiques, restaurants and office space with a USPS concession.", "The Kingsbridge Armory, often cited as the largest armory in the world, is currently slated for redevelopment.Under consideration for future development is the construction of a platform over the New York City Subway's Concourse Yard adjacent to Lehman College.", "The construction would permit approximately of development and would cost .Despite significant investment compared to the post war period, many exacerbated social problems remain including high rates of violent crime, substance abuse, overcrowding, and substandard housing conditions.", "The Bronx has the highest rate of poverty in New York City, and the greater South Bronx is the poorest area." ], [ "Geography", "Location of the Bronx (red) within New York City (remainder white)===Location and physical features===According to the U.S. Census Bureau, Bronx County has a total area of , of which is land and (27%) is water.The Bronx is New York City's northernmost borough, New York State's southernmost mainland county and the only part of New York City that is almost entirely on the North American mainland.", "The bedrock of the West Bronx is primarily '''Fordham gneiss''', a high-grade heavily banded metamorphic rock containing significant amounts of pink feldspar.", "Marble Hill – politically part of Manhattan but now physically attached to the Bronx – is so-called because of the formation of Inwood marble there as well as in Inwood, Manhattan and parts of the Bronx and Westchester County.The Hudson River separates the Bronx on the west from Alpine, Tenafly and Englewood Cliffs in Bergen County, New Jersey;

language and ''lingua franca''.", "** ** Belgium's linguistic diversity and related political conflicts are reflected in its complex system of governance, made up of six different governments.Since the Middle Ages, Belgium's central location has meant that the area has been relatively prosperous, connected commercially and politically to its bigger neighbours.", "The country as it exists today was established following the 1830 Belgian Revolution, when it seceded from the United Kingdom of the Netherlands, which had incorporated the Southern Netherlands (which comprised most of modern-day Belgium) after the Congress of Vienna in 1815.The name chosen for the new state is derived from the Latin word '''', used in Julius Caesar's \"Gallic Wars\", to describe a nearby region in the period around 55 BCE.", "Belgium has also been the battleground of European powers, earning the moniker \"the Battlefield of Europe\",*—and as such coined for Belgium:* (See also The Nuttall Encyclopaedia) a

annexed the territory as a colony.", "The Belgian colonies gained independence between 1960 and 1962.The second half of the 20th century was marked by rising tensions between the Dutch-speaking and the French-speaking citizens fueled by differences in language and culture and the unequal economic development of Flanders and Wallonia.", "This continuing antagonism has led to several far-reaching state reforms, resulting in the transition from a unitary to a federal arrangement between 1970 and 1993.Despite the reforms, tensions have persisted: there is particularly significant separatist sentiment among the Flemish, language laws such as the municipalities with language facilities have been the source of much controversy, and the government formation period following the 2010 federal election set the world record at 589 days.", "Unemployment in Wallonia is more than double that of Flanders, which boomed after the Second World War.Belgium is a developed country, with an advanced

word \"''Belgium''\" to refer to a politically dominant part of that region, which is now in northernmost France.", "Modern Belgium corresponds to the lands of the most northerly Belgae; the Morini, Menapii, Nervii, Germani Cisrhenani, and Aduatuci; whom Caesar found particularly warlike and economically undeveloped.", "Caesar described this region as having strong kinship links to the Germanic tribes east of the Rhine.", "The area around Arlon in southern Belgium was a part of the country of the Treveri.After Caesar's conquests, ''Gallia Belgica'' came to be the Latin name of a large Roman province covering most of Northern Gaul, including the Treveri.", "However, areas closer to the lower Rhine frontier, including the eastern part of modern Belgium, subsequently became part of the frontier province of ''Germania Inferior'', which continued to interact with their neighbours outside the empire.", "At the time when central government collapsed in the Western Roman Empire, the Roman provinces of Belgica and Germania were inhabited by a mix of a Romanized population and Germanic-speaking Franks who came to dominate the military and political class.===Middle Ages===During the 5th century, the area came under the rule of the Frankish Merovingian kings, who initially established a kingdom ruling over the Romanized population in what is now northern France, and then conquered the other Frankish kingdoms.", "During the 8th century, the empire of the Franks came to be ruled by the Carolingian dynasty, whose centre of power included the area which is now eastern Belgium.",

boundaries.", "Most of modern Belgium was in the Middle Kingdom, later known as Lotharingia, but the coastal county of Flanders, west of the Scheldt, became the northernmost part of West Francia, the predecessor of France.", "In 870 in the Treaty of Meerssen, modern Belgium lands all became part of the western kingdom for a period, but in 880 in the Treaty of Ribemont, Lotharingia came under the lasting control of the eastern kingdom, which became the Holy Roman Empire.", "The lordships and bishoprics along the \"March\" (frontier) between the two great kingdoms maintained important connections between each other.", "For example, the county of Flanders expanded over the Scheldt into the empire, and during several periods was ruled by the same lords as the county of Hainaut.In the 13th and 14th centuries, the cloth industry and commerce boomed especially in the County of Flanders and it became one of the richest areas in Europe.", "This prosperity played a role in conflicts between Flanders and the king of France.", "Famously, Flemish militias scored a surprise victory at the Battle of the Golden Spurs against a strong force of mounted knights in 1302, but France soon regained control of the rebellious province.===Burgundian and Habsburg Netherlands===Burgundian State of Charles the Bold in the 15th centuryIn the 15th century, the Duke of Burgundy in France took

families of Austria, Castile and Aragon.", "With the Pragmatic Sanction of 1549 he gave the Seventeen Provinces more legitimacy as a stable entity, rather than just a temporary personal union.", "He also increased the influence of these Netherlands over the Prince-Bishopric of Liège, which continued to exist as a large semi-independent enclave.===Spanish and Austrian Netherlands===The Eighty Years' War (1568–1648) was triggered by the Spanish government's policy towards Protestantism, which was becoming popular in the Low Countries.", "The rebellious northern United Provinces (''Belgica Foederata'' in Latin, the \"Federated Netherlands\") eventually separated from the Southern Netherlands (''Belgica Regia'', the \"Royal Netherlands\").", "The southern part continued to be ruled

on representation of the main cultural communities.Since about 1970, the significant national Belgian political parties have split into distinct components that mainly represent the political and linguistic interests of these communities.The major parties in each community, though close to the political center, belong to three main groups: Christian Democrats, Liberals, and Social Democrats.Further notable parties came into being well after the middle of last century, mainly to represent linguistic, nationalist, or environmental interests, and recently smaller ones of some

Burgundian and Habsburg courts, in the 19th century it was necessary to speak French to belong to the governing upper class, and those who could only speak Dutch were effectively second-class citizens.", "Late that century, and continuing into the 20th century, Flemish movements evolved to counter this situation.While the people in Southern Belgium spoke French or dialects of French, and most Brusselers adopted French as their first language, the Flemings refused to do so and succeeded progressively in making Dutch an equal language in the education system.", "Following World War II, Belgian politics became increasingly dominated by the autonomy of its two main linguistic communities.", "Intercommunal tensions rose and the constitution was amended to minimize the potential for conflict.Based on the four language areas defined in 1962–63 (the Dutch, bilingual, French and German language areas), consecutive revisions of the country's constitution in 1970, 1980, 1988 and 1993 established a unique form of a federal state with segregated political power into three levels:# The federal government, based in Brussels.# The three language communities:#* the Flemish Community (Dutch-speaking);#* the French Community (French-speaking);#* the German-speaking Community.# The three regions:#* the Flemish Region, subdivided into five provinces;#* the Walloon Region, subdivided into five provinces;#* the Brussels-Capital Region.The constitutional language areas determine the official languages in their municipalities, as well as the geographical limits of the empowered institutions for specific matters.", "Although this would allow for seven parliaments and governments when the Communities and Regions were created in 1980, Flemish politicians decided to merge both.", "Thus the Flemings just have one single institutional body of parliament and government is empowered for all except federal and specific municipal matters.The overlapping boundaries of the Regions and Communities have created two notable peculiarities: the territory of the Brussels-Capital Region (which came into existence nearly a decade after the other regions) is included in both the Flemish and French Communities, and the territory of the German-speaking Community lies wholly within the Walloon Region.", "Conflicts about jurisdiction between the bodies are resolved by the

government employs around 12% of the civil servants.Communities exercise their authority only within linguistically determined geographical boundaries, originally oriented towards the individuals of a Community's language: culture (including audiovisual media), education and the use of the relevant language.", "Extensions to personal matters less directly connected with language comprise health policy (curative and preventive medicine) and assistance to individuals (protection of youth, social welfare, aid to families, immigrant assistance services, and so on.", ").Regions have authority in fields that can be broadly associated with their territory.", "These include economy, employment, agriculture, water policy, housing, public works, energy, transport, the environment, town and country planning, nature conservation, credit and foreign trade.", "They supervise the provinces, municipalities and intercommunal utility companies.In several fields, the different levels each have their own say on specifics.", "With education, for instance, the autonomy of the Communities neither includes decisions about the compulsory aspect nor allows for setting minimum requirements for awarding qualifications, which remain federal matters.", "Each level of government can be involved in scientific research and international relations associated with its powers.", "The treaty-making power of the Regions' and Communities' Governments is the broadest of all the Federating units of all the Federations all over the world.===Foreign relations===The Berlaymont building in Brussels, seat of the

[ [ "Blues" ], [ "Introduction", "'''Blues''' is a music genre and musical form that originated in the Deep South of the United States around the 1860s.", "Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads from the African-American culture.", "The blues form is ubiquitous in jazz, rhythm and blues, and rock and roll, and is characterized by the call-and-response pattern, the blues scale, and specific chord progressions, of which the twelve-bar blues is the most common.", "Blue notes (or \"worried notes\"), usually thirds, fifths or sevenths flattened in pitch, are also an essential part of the sound.", "Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove.One of the first wholly American styles of music to gain traction and recognition across the world was blues music, developed in the American South by African slaves, many of whom were Muslim.", "An estimated 30% of African slaves brought to America were Muslim.", "Blues music is heavily influenced by \"field holler\" songs, sung by the slaves as they worked in the fields.", "The Muslim slaves added their own flair to their field holler songs, with African diaspora historian Sylviane Douf describing the way they sang \"words that seem to quiver and shake\" as very reminiscent of the Adh''an'', or Islamic call to prayer.", "\"The Blues\" is also characterized by its lyrics, bass lines, and instrumentation.", "Early traditional blues verses consisted of a single line repeated four times.", "It was only in the first decades of the 20th century that the most common current structure became standard: the AAB pattern, consisting of a line sung over the four first bars, its repetition over the next four, and then a longer concluding line over the last bars.", "Early blues frequently took the form of a loose narrative, often relating the racial discrimination and other challenges experienced by African-Americans.Many elements, such as the call-and-response format and the use of blue notes, can be traced back to the music of Africa.", "The origins of the blues are also closely related to the religious music of the Afro-American community, the spirituals.", "The first appearance of the blues is often dated to after the ending of slavery.", "Later, the development of juke joints.", "It is associated with the newly acquired freedom of the former slaves.", "Chroniclers began to report about blues music at the dawn of the 20th century.", "The first publication of blues sheet music was in 1908.Blues has since evolved from unaccompanied vocal music and oral traditions of slaves into a wide variety of styles and subgenres.", "Blues subgenres include country blues, Delta blues and Piedmont blues, as well as urban blues styles such as Chicago blues and West Coast blues.", "World War II marked the transition from acoustic to electric blues and the progressive opening of blues music to a wider audience, especially white listeners.", "In the 1960s and 1970s, a hybrid form called blues rock developed, which blended blues styles with rock music." ], [ "Etymology", "The term 'Blues' may have originated from \"blue devils\", meaning melancholy and sadness.", "An early use of the term in this sense is in George Colman's one-act farce ''Blue Devils'' (1798).", "The phrase 'blue devils' may also have been derived from a British usage of the 1600s referring to the \"intense visual hallucinations that can accompany severe alcohol withdrawal\".", "As time went on, the phrase lost the reference to devils and came to mean a state of agitation or depression.", "By the 1800s in the United States, the term \"blues\" was associated with drinking alcohol, a meaning which survives in the phrase 'blue law', which prohibits the sale of alcohol on Sunday.In 1827, it was in the sense of a sad state of mind that John James Audubon wrote to his wife that he \"had the blues\".", "The phrase \"the blues\" was written by Charlotte Forten, then aged 25, in her diary on December 14, 1862.She was a free-born black woman from Pennsylvania who was working as a schoolteacher in South Carolina, instructing both slaves and freedmen, and wrote that she \"came home with the blues\" because she felt lonesome and pitied herself.", "She overcame her depression and later noted a number of songs, such as \"Poor Rosy\", that were popular among the slaves.", "Although she admitted being unable to describe the manner of singing she heard, Forten wrote that the songs \"can't be sung without a full heart and a troubled spirit\", conditions that have inspired countless blues songs.Though the use of the phrase in African-American music may be older, it has been attested to in print since 1912, when Hart Wand's \"Dallas Blues\" became the first copyrighted blues composition.", "In lyrics, the phrase is often used to describe a depressed mood." ], [ "Lyrics", "American blues singer Ma Rainey (1886–1939), the \"Mother of the Blues\"Early traditional blues verses often consisted of a single line repeated four times.", "However, the most common structure of blues lyrics today was established in the first few decades of the 20th century, known as the \"AAB\" pattern.", "This structure consists of a line sung over the first four bars, its repetition over the next four, and a longer concluding line over the last bars.", "This pattern can be heard in some of the first published blues songs, such as \"Dallas Blues\" (1912) and \"Saint Louis Blues\" (1914).", "According to W.C.", "Handy, the \"AAB\" pattern was adopted to avoid the monotony of lines repeated three times.", "The lyrics are often sung in a rhythmic talk style rather than a melody, resembling a form of talking blues.Early blues frequently took the form of a loose narrative.", "African-American singers voiced their \"personal woes in a world of harsh reality: a lost love, the cruelty of police officers, oppression at the hands of white folk, and hard times\".", "This melancholy has led to the suggestion of an Igbo origin for blues, because of the reputation the Igbo had throughout plantations in the Americas for their melancholic music and outlook on life when they were enslaved.", "Other historians have argued that there is little evidence of Sub-Sahelian influence in the blues as \"elaborate polyrhythm, percussion on African drums (as opposed to European drums), and collective participation\" which are characteristic of West-Central African music below the savannah, are conspicuously absent.", "According to the historian Paul Oliver, \"the roots of the blues were not to be found in the coastal and forest regions of Africa.", "Rather... the blues was rooted in ... the savanna hinterland, from Senegambia through Mali, Burkina Faso, Northern Ghana, Niger, and northern Nigeria\".", "Additionally, ethnomusicologist John Storm Roberts has argued that \"The parallels between African savanna-belt string-playing and the techniques of many blues guitarists are remarkable.", "The big kora of Senegal and Guinea are played in a rhythmic-melodic style that uses constantly changing rhythms, often providing a ground bass overlaid with complex treble patterns, while vocal supplies a third rhythmic layer.", "Similar techniques can be found in hundreds of blues records\".The lyrics often relate troubles experienced within African American society.", "For instance Blind Lemon Jefferson's \"Rising High Water Blues\" (1927) tells of the Great Mississippi Flood of 1927:Although the blues gained an association with misery and oppression, the lyrics could also be humorous and raunchy:Hokum blues celebrated both comedic lyrical content and a boisterous, farcical performance style.", "Tampa Red and Georgia Tom's \"It's Tight Like That\" (1928) is a sly wordplay with the double meaning of being \"tight\" with someone, coupled with a more salacious physical familiarity.", "Blues songs with sexually explicit lyrics were known as dirty blues.", "The lyrical content became slightly simpler in postwar blues, which tended to focus on relationship woes or sexual worries.", "Lyrical themes that frequently appeared in prewar blues, such as economic depression, farming, devils, gambling, magic, floods and drought, were less common in postwar blues.The writer Ed Morales claimed that Yoruba mythology played a part in early blues, citing Robert Johnson's \"Cross Road Blues\" as a \"thinly veiled reference to Eleggua, the orisha in charge of the crossroads\".", "However, the Christian influence was far more obvious.", "The repertoires of many seminal blues artists, such as Charley Patton and Skip James, included religious songs or spirituals.", "Reverend Gary Davis and Blind Willie Johnson are examples of artists often categorized as blues musicians for their music, although their lyrics clearly belong to spirituals." ], [ "Form", "The blues form is a cyclic musical form in which a repeating progression of chords mirrors the call and response scheme commonly found in African and African-American music.", "During the first decades of the 20th century blues music was not clearly defined in terms of a particular chord progression.", "With the popularity of early performers, such as Bessie Smith, use of the twelve-bar blues spread across the music industry during the 1920s and 1930s.", "Other chord progressions, such as 8-bar forms, are still considered blues; examples include \"How Long Blues\", \"Trouble in Mind\", and Big Bill Broonzy's \"Key to the Highway\".", "There are also 16-bar blues, such as Ray Charles's instrumental \"Sweet 16 Bars\" and Herbie Hancock's \"Watermelon Man\".", "Idiosyncratic numbers of bars are occasionally used, such as the 9-bar progression in \"Sitting on Top of the World\", by Walter Vinson.Chords played over a 12-bar scheme:Chords for a blues in C:II or IVII7IVIVII7VV or IVII or VCCCC7FFCC7GGCCThe basic 12-bar lyric framework of many blues compositions is reflected by a standard harmonic progression of 12 bars in a 4/4 time signature.", "The blues chords associated to a twelve-bar blues are typically a set of three different chords played over a 12-bar scheme.", "They are labeled by Roman numbers referring to the degrees of the progression.", "For instance, for a blues in the key of C, C is the tonic chord (I) and F is the subdominant (IV).The last chord is the dominant (V) turnaround, marking the transition to the beginning of the next progression.", "The lyrics generally end on the last beat of the tenth bar or the first beat of the 11th bar, and the final two bars are given to the instrumentalist as a break; the harmony of this two-bar break, the turnaround, can be extremely complex, sometimes consisting of single notes that defy analysis in terms of chords.Much of the time, some or all of these chords are played in the harmonic seventh (7th) form.", "The use of the harmonic seventh interval is characteristic of blues and is popularly called the \"blues seven\".", "Blues seven chords add to the harmonic chord a note with a frequency in a 7:4 ratio to the fundamental note.", "At a 7:4 ratio, it is not close to any interval on the conventional Western diatonic scale.", "For convenience or by necessity it is often approximated by a minor seventh interval or a dominant seventh chord.A minor pentatonic scale; In melody, blues is distinguished by the use of the flattened third, fifth and seventh of the associated major scale.Blues shuffles or walking bass reinforce the trance-like rhythm and call-and-response, and they form a repetitive effect called a groove.", "Characteristic of the blues since its Afro-American origins, the shuffles played a central role in swing music.", "The simplest shuffles, which were the clearest signature of the R&B wave that started in the mid-1940s, were a three-note riff on the bass strings of the guitar.", "When this riff was played over the bass and the drums, the groove \"feel\" was created.", "Shuffle rhythm is often vocalized as \"''dow'', da ''dow'', da ''dow'', da\" or \"''dump'', da ''dump'', da ''dump'', da\": it consists of uneven, or \"swung\", eighth notes.", "On a guitar this may be played as a simple steady bass or it may add to that stepwise quarter note motion from the fifth to the sixth of the chord and back." ], [ "History", "===Origins===Hart Wand's \"Dallas Blues\" was published in 1912; W.C.", "Handy's \"The Memphis Blues\" followed in the same year.", "The first recording by an African American singer was Mamie Smith's 1920 rendition of Perry Bradford's \"Crazy Blues\".", "But the origins of the blues were some decades earlier, probably around 1890.This music is poorly documented, partly because of racial discrimination in U.S. society, including academic circles, and partly because of the low rate of literacy among rural African Americans at the time.Reports of blues music in southern Texas and the Deep South were written at the dawn of the 20th century.", "Charles Peabody mentioned the appearance of blues music at Clarksdale, Mississippi, and Gate Thomas reported similar songs in southern Texas around 1901–1902.These observations coincide more or less with the recollections of Jelly Roll Morton, who said he first heard blues music in New Orleans in 1902; Ma Rainey, who remembered first hearing the blues in the same year in Missouri; and W.C.", "Handy, who first heard the blues in Tutwiler, Mississippi, in 1903.The first extensive research in the field was performed by Howard W. Odum, who published an anthology of folk songs from Lafayette County, Mississippi, and Newton County, Georgia, between 1905 and 1908.The first non-commercial recordings of blues music, termed ''proto-blues'' by Paul Oliver, were made by Odum for research purposes at the beginning of the 20th century.", "They are now lost.Musicologist John Lomax (left) shaking hands with musician \"Uncle\" Rich Brown in Sumterville, Alabama Other recordings that are still available were made in 1924 by Lawrence Gellert.", "Later, several recordings were made by Robert W. Gordon, who became head of the Archive of American Folk Songs of the Library of Congress.", "Gordon's successor at the library was John Lomax.", "In the 1930s, Lomax and his son Alan made a large number of non-commercial blues recordings that testify to the huge variety of proto-blues styles, such as field hollers and ring shouts.", "A record of blues music as it existed before 1920 can also be found in the recordings of artists such as Lead Belly and Henry Thomas.", "All these sources show the existence of many different structures distinct from twelve-, eight-, or sixteen-bar.The social and economic reasons for the appearance of the blues are not fully known.", "The first appearance of the blues is usually dated after the Emancipation Act of 1863, between 1860s and 1890s, a period that coincides with post-emancipation and later, the establishment of juke joints as places where African-Americans went to listen to music, dance, or gamble after a hard day's work.", "This period corresponds to the transition from slavery to sharecropping, small-scale agricultural production, and the expansion of railroads in the southern United States.", "Several scholars characterize the development of blues music in the early 1900s as a move from group performance to individualized performance.", "They argue that the development of the blues is associated with the newly acquired freedom of the enslaved people.According to Lawrence Levine, \"there was a direct relationship between the national ideological emphasis upon the individual, the popularity of Booker T. Washington's teachings, and the rise of the blues.\"", "Levine stated that \"psychologically, socially, and economically, African-Americans were being acculturated in a way that would have been impossible during slavery, and it is hardly surprising that their secular music reflected this as much as their religious music did.", "\"There are few characteristics common to all blues music, because the genre took its shape from the idiosyncrasies of individual performers.", "However, there are some characteristics that were present long before the creation of the modern blues.", "Call-and-response shouts were an early form of blues-like music; they were a \"functional expression ... style without accompaniment or harmony and unbounded by the formality of any particular musical structure\".", "A form of this pre-blues was heard in slave ring shouts and field hollers, expanded into \"simple solo songs laden with emotional content\".Blues has evolved from the unaccompanied vocal music and oral traditions of slaves imported from West Africa and rural blacks into a wide variety of styles and subgenres, with regional variations across the United States.", "Although blues (as it is now known) can be seen as a musical style based on both European harmonic structure and the African call-and-response tradition that transformed into an interplay of voice and guitar, the blues form itself bears no resemblance to the melodic styles of the West African griots.", "Additionally, there are theories that the four-beats-per-measure structure of the blues might have its origins in the Native American tradition of pow wow drumming.", "Some scholars identify strong influences on the blues from the melodic structures of certain West African musical styles of the savanna and sahel.", "Lucy Durran finds similarities with the melodies of the Bambara people, and to a lesser degree, the Soninke people and Wolof people, but not as much of the Mandinka people.", "Gerard Kubik finds similarities to the melodic styles of both the west African savanna and central Africa, both of which were sources of enslaved people.No specific African musical form can be identified as the single direct ancestor of the blues.", "However the call-and-response format can be traced back to the music of Africa.", "That blue notes predate their use in blues and have an African origin is attested to by \"A Negro Love Song\", by the English composer Samuel Coleridge-Taylor, from his ''African Suite for Piano'', written in 1898, which contains blue third and seventh notes.The Diddley bow (a homemade one-stringed instrument found in parts of the American South sometimes referred to as a ''jitterbug'' or a ''one-string'' in the early twentieth century) and the banjo are African-derived instruments that may have helped in the transfer of African performance techniques into the early blues instrumental vocabulary.", "The banjo seems to be directly imported from West African music.", "It is similar to the musical instrument that griots and other Africans such as the Igbo played (called halam or akonting by African peoples such as the Wolof, Fula and Mandinka).", "However, in the 1920s, when country blues began to be recorded, the use of the banjo in blues music was quite marginal and limited to individuals such as Papa Charlie Jackson and later Gus Cannon.Blues music also adopted elements from the \"Ethiopian airs\", minstrel shows and Negro spirituals, including instrumental and harmonic accompaniment.", "The style also was closely related to ragtime, which developed at about the same time, though the blues better preserved \"the original melodic patterns of African music\".The musical forms and styles that are now considered the blues as well as modern country music arose in the same regions of the southern United States during the 19th century.", "Recorded blues and country music can be found as far back as the 1920s, when the record industry created the marketing categories \"race music\" and \"hillbilly music\" to sell music by blacks for blacks and by whites for whites, respectively.", "At the time, there was no clear musical division between \"blues\" and \"country\", except for the ethnicity of the performer, and even that was sometimes documented incorrectly by record companies.Though musicologists can now attempt to define the blues narrowly in terms of certain chord structures and lyric forms thought to have originated in West Africa, audiences originally heard the music in a far more general way: it was simply the music of the rural south, notably the Mississippi Delta.", "Black and white musicians shared the same repertoire and thought of themselves as \"songsters\" rather than blues musicians.", "The notion of blues as a separate genre arose during the black migration from the countryside to urban areas in the 1920s and the simultaneous development of the recording industry.", "''Blues'' became a code word for a record designed to sell to black listeners.The origins of the blues are closely related to the religious music of Afro-American community, the spirituals.", "The origins of spirituals go back much further than the blues, usually dating back to the middle of the 18th century, when the slaves were Christianized and began to sing and play Christian hymns, in particular those of Isaac Watts, which were very popular.", "Before the blues gained its formal definition in terms of chord progressions, it was defined as the secular counterpart of spirituals.", "It was the low-down music played by rural blacks.Depending on the religious community a musician belonged to, it was more or less considered a sin to play this low-down music: blues was the devil's music.", "Musicians were therefore segregated into two categories: gospel singers and blues singers, guitar preachers and songsters.", "However, when rural black music began to be recorded in the 1920s, both categories of musicians used similar techniques: call-and-response patterns, blue notes, and slide guitars.", "Gospel music was nevertheless using musical forms that were compatible with Christian hymns and therefore less marked by the blues form than its secular counterpart.===Pre-war blues===The American sheet music publishing industry produced a great deal of ragtime music.", "By 1912, the sheet music industry had published three popular blues-like compositions, precipitating the Tin Pan Alley adoption of blues elements: \"Baby Seals' Blues\", by \"Baby\" Franklin Seals (arranged by Artie Matthews); \"Dallas Blues\", by Hart Wand; and \"The Memphis Blues\", by W.C. Handy.Saint Louis Blues\" (1914)Handy was a formally trained musician, composer and arranger who helped to popularize the blues by transcribing and orchestrating blues in an almost symphonic style, with bands and singers.", "He became a popular and prolific composer, and billed himself as the \"Father of the Blues\"; however, his compositions can be described as a fusion of blues with ragtime and jazz, a merger facilitated using the Cuban habanera rhythm that had long been a part of ragtime; Handy's signature work was the \"Saint Louis Blues\".In the 1920s, the blues became a major element of African American and American popular music, also reaching white audiences via Handy's arrangements and the classic female blues performers.", "These female performers became perhaps the first African American \"superstars\", and their recording sales demonstrated \"a huge appetite for records made by and for black people.\"", "The blues evolved from informal performances in bars to entertainment in theaters.", "Blues performances were organized by the Theater Owners Booking Association in nightclubs such as the Cotton Club and juke joints such as the bars along Beale Street in Memphis.", "Several record companies, such as the American Record Corporation, Okeh Records, and Paramount Records, began to record African-American music.As the recording industry grew, country blues performers like Bo Carter, Jimmie Rodgers, Blind Lemon Jefferson, Lonnie Johnson, Tampa Red and Blind Blake became more popular in the African American community.", "Kentucky-born Sylvester Weaver was in 1923 the first to record the slide guitar style, in which a guitar is fretted with a knife blade or the sawed-off neck of a bottle.", "The slide guitar became an important part of the Delta blues.", "The first blues recordings from the 1920s are categorized as a traditional, rural country blues and a more polished city or urban blues.Country blues performers often improvised, either without accompaniment or with only a banjo or guitar.", "Regional styles of country blues varied widely in the early 20th century.", "The (Mississippi) Delta blues was a rootsy sparse style with passionate vocals accompanied by slide guitar.", "The little-recorded Robert Johnson combined elements of urban and rural blues.", "In addition to Robert Johnson, influential performers of this style included his predecessors Charley Patton and Son House.", "Singers such as Blind Willie McTell and Blind Boy Fuller performed in the southeastern \"delicate and lyrical\" Piedmont blues tradition, which used an elaborate ragtime-based fingerpicking guitar technique.", "Georgia also had an early slide tradition, with Curley Weaver, Tampa Red, \"Barbecue Bob\" Hicks and James \"Kokomo\" Arnold as representatives of this style.The lively Memphis blues style, which developed in the 1920s and 1930s near Memphis, Tennessee, was influenced by jug bands such as the Memphis Jug Band or the Gus Cannon's Jug Stompers.", "Performers such as Frank Stokes, Sleepy John Estes, Robert Wilkins, Joe McCoy, Casey Bill Weldon and Memphis Minnie used a variety of unusual instruments such as washboard, fiddle, kazoo or mandolin.", "Memphis Minnie was famous for her virtuoso guitar style.", "Pianist Memphis Slim began his career in Memphis, but his distinct style was smoother and had some swing elements.", "Many blues musicians based in Memphis moved to Chicago in the late 1930s or early 1940s and became part of the urban blues movement.Bessie Smith, an early blues singer, known for her powerful voice====Urban blues====City or urban blues styles were more codified and elaborate, as a performer was no longer within their local, immediate community, and had to adapt to a larger, more varied audience's aesthetic.", "Classic female urban and vaudeville blues singers were popular in the 1920s, among them \"the big three\"—Gertrude \"Ma\" Rainey, Bessie Smith, and Lucille Bogan.", "Mamie Smith, more a vaudeville performer than a blues artist, was the first African American to record a blues song, in 1920; her second record, \"Crazy Blues\", sold 75,000 copies in its first month.", "Ma Rainey, the \"Mother of Blues\", and Bessie Smith each \"sang around center tones, perhaps in order to project her voice more easily to the back of a room\".", "Smith would \"sing a song in an unusual key, and her artistry in bending and stretching notes with her beautiful, powerful contralto to accommodate her own interpretation was unsurpassed\".In 1920, the vaudeville singer Lucille Hegamin became the second black woman to record blues when she recorded \"The Jazz Me Blues\", and Victoria Spivey, sometimes called Queen Victoria or Za Zu Girl, had a recording career that began in 1926 and spanned forty years.", "These recordings were typically labeled \"race records\" to distinguish them from records sold to white audiences.", "Nonetheless, the recordings of some of the classic female blues singers were purchased by white buyers as well.", "These blueswomen's contributions to the genre included \"increased improvisation on melodic lines, unusual phrasing which altered the emphasis and impact of the lyrics, and vocal dramatics using shouts, groans, moans, and wails.", "The blues women thus effected changes in other types of popular singing that had spin-offs in jazz, Broadway musicals, torch songs of the 1930s and 1940s, gospel, rhythm and blues, and eventually rock and roll.", "\"Urban male performers included popular black musicians of the era, such as Tampa Red, Big Bill Broonzy and Leroy Carr.", "An important label of this era was the Chicago-based Bluebird Records.", "Before World War II, Tampa Red was sometimes referred to as \"the Guitar Wizard\".", "Carr accompanied himself on the piano with Scrapper Blackwell on guitar, a format that continued well into the 1950s with artists such as Charles Brown and even Nat \"King\" Cole.A typical boogie-woogie bass line Boogie-woogie was another important style of 1930s and early 1940s urban blues.", "While the style is often associated with solo piano, boogie-woogie was also used to accompany singers and, as a solo part, in bands and small combos.", "Boogie-woogie style was characterized by a regular bass figure, an ostinato or riff and shifts of level in the left hand, elaborating each chord and trills and decorations in the right hand.", "Boogie-woogie was pioneered by the Chicago-based Jimmy Yancey and the Boogie-Woogie Trio (Albert Ammons, Pete Johnson and Meade Lux Lewis).", "Chicago boogie-woogie performers included Clarence \"Pine Top\" Smith and Earl Hines, who \"linked the propulsive left-hand rhythms of the ragtime pianists with melodic figures similar to those of Armstrong's trumpet in the right hand\".", "The smooth Louisiana style of Professor Longhair and, more recently, Dr. John blends classic rhythm and blues with blues styles.Another development in this period was big band blues.", "The \"territory bands\" operating out of Kansas City, the Bennie Moten orchestra, Jay McShann, and the Count Basie Orchestra were also concentrating on the blues, with 12-bar blues instrumentals such as Basie's \"One O'Clock Jump\" and \"Jumpin' at the Woodside\" and boisterous \"blues shouting\" by Jimmy Rushing on songs such as \"Going to Chicago\" and \"Sent for You Yesterday\".", "A well-known big band blues tune is Glenn Miller's \"In the Mood\".", "In the 1940s, the jump blues style developed.", "Jump blues grew up from the boogie-woogie wave and was strongly influenced by big band music.", "It uses saxophone or other brass instruments and the guitar in the rhythm section to create a jazzy, up-tempo sound with declamatory vocals.", "Jump blues tunes by Louis Jordan and Big Joe Turner, based in Kansas City, Missouri, influenced the development of later styles such as rock and roll and rhythm and blues.", "Dallas-born T-Bone Walker, who is often associated with the California blues style, performed a successful transition from the early urban blues à la Lonnie Johnson and Leroy Carr to the jump blues style and dominated the blues-jazz scene at Los Angeles during the 1940s.===1950s===The transition from country blues to urban blues that began in the 1920s was driven by the successive waves of economic crisis and booms that led many rural blacks to move to urban areas, in a movement known as the Great Migration.", "The long boom following World War II induced another massive migration of the African-American population, the Second Great Migration, which was accompanied by a significant increase of the real income of the urban blacks.", "The new migrants constituted a new market for the music industry.", "The term ''race record'', initially used by the music industry for African-American music, was replaced by the term ''rhythm and blues''.", "This rapidly evolving market was mirrored by ''Billboard'' magazine's Rhythm & Blues chart.", "This marketing strategy reinforced trends in urban blues music such as the use of electric instruments and amplification and the generalization of the blues beat, the blues shuffle, which became ubiquitous in rhythm and blues (R&B).", "This commercial stream had important consequences for blues music, which, together with jazz and gospel music, became a component of R&B.John Lee HookerAfter World War II, new styles of electric blues became popular in cities such as Chicago, Memphis, Detroit and St. Louis.", "Electric blues used electric guitars, double bass (gradually replaced by bass guitar), drums, and harmonica (or \"blues harp\") played through a microphone and a PA system or an overdriven guitar amplifier.", "Chicago became a center for electric blues from 1948 on, when Muddy Waters recorded his first success, \"I Can't Be Satisfied\".", "Chicago blues is influenced to a large extent by Delta blues,

[ [ "Benjamin Lee Whorf" ], [ "Introduction", "'''Benjamin Lee Whorf''' (; April 24, 1897 – July 26, 1941) was an American linguist and fire prevention engineer who is famous for proposing the \"Sapir–Whorf hypothesis.\"", "He believed that the structures of different languages shape how their speakers perceive and conceptualize the world.", "Whorf saw this idea, named after him and his mentor Edward Sapir, as having implications similar to Einstein's principle of physical relativity.", "However, the concept originated from 19th-century philosophy and thinkers like Wilhelm von Humboldt and Wilhelm Wundt.Whorf initially pursued chemical engineering but developed an interest in linguistics, particularly Biblical Hebrew and indigenous Mesoamerican languages.", "His groundbreaking work on the Nahuatl language earned him recognition, and he received a grant to study it further in Mexico.", "He presented influential papers on Nahuatl upon his return.", "Whorf later studied linguistics with Edward Sapir at Yale University while working as a fire prevention engineer.During his time at Yale, Whorf worked on describing the Hopi language and made notable claims about its perception of time.", "He also conducted research on the Uto-Aztecan languages, publishing influential papers.", "In 1938, he substituted for Sapir, teaching a seminar on American Indian linguistics.", "Whorf's contributions extended beyond linguistic relativity; he wrote a grammar sketch of Hopi, studied Nahuatl dialects, proposed a deciphering of Maya hieroglyphic writing, and contributed to Uto-Aztecan reconstruction.After Whorf's death from cancer in 1941, his linguist friends curated his manuscripts and promoted his ideas regarding language, culture, and cognition.", "However, in the 1960s, his views fell out of favor due to criticisms claiming his ideas were untestable and poorly formulated.", "In recent decades, interest in Whorf's work has resurged, with scholars reevaluating his ideas and engaging in a more in-depth understanding of his theories.", "The field of linguistic relativity remains an active area of research in psycholinguistics and linguistic anthropology, generating ongoing debates between relativism and universalism.", "Whorf's contributions to linguistics, such as the allophone and the cryptotype, have been widely accepted." ], [ "Biography", "=== Early life ===The son of Harry Church Whorf and Sarah Edna Lee Whorf, Benjamin Lee Whorf was born on April 24, 1897, in Winthrop, Massachusetts.", "Harry Church Whorf was an artist, intellectual, and designer – first working as a commercial artist and later as a dramatist.", "Whorf had two younger brothers, John and Richard, who both went on to become notable artists.", "John became an internationally renowned painter and illustrator; Richard was an actor in films such as ''Yankee Doodle Dandy'' and later an Emmy-nominated television director of such shows as ''The Beverly Hillbillies''.", "Whorf was the intellectual of the three and started conducting chemical experiments with his father's photographic equipment at a young age.", "He was also an avid reader, interested in botany, astrology, and Middle American prehistory.", "He read William H. Prescott's ''Conquest of Mexico'' several times.", "At the age of 17, he began keeping a copious diary in which he recorded his thoughts and dreams.=== Career in fire prevention ===Whorf graduated from the Massachusetts Institute of Technology in 1918 with a degree in chemical engineering where his academic performance was of average quality.", "In 1920, he married Celia Inez Peckham, who became the mother of his three children, Raymond Ben, Robert Peckham and Celia Lee.", "Around the same time he began work as a fire prevention engineer (an inspector) for the Hartford Fire Insurance Company.", "He was particularly good at the job and was highly commended by his employers.", "His job required him to travel to production facilities throughout New England to be inspected.", "One anecdote describes him arriving at a chemical plant in which he was denied access by the director because he would not allow anyone to see the production procedure which was a trade secret.", "Having been told what the plant produced, Whorf wrote a chemical formula on a piece of paper, saying to the director: \"I think this is what you're doing\".", "The surprised director asked Whorf how he knew about the secret procedure, and he simply answered: \"You couldn't do it in any other way.", "\"Whorf helped to attract new customers to the Fire Insurance Company; they favored his thorough inspections and recommendations.", "Another famous anecdote from his job was used by Whorf to argue that language use affects habitual behavior.", "Whorf described a workplace in which full gasoline drums were stored in one room and empty ones in another; he said that because of flammable vapor the \"empty\" drums were more dangerous than those that were full, although workers handled them less carefully to the point that they smoked in the room with \"empty\" drums, but not in the room with full ones.", "Whorf argued that by habitually speaking of the vapor-filled drums as empty and by extension as inert, the workers were oblivious to the risk posed by smoking near the \"empty drums\".=== Early interest in religion and language ===Whorf was a spiritual man throughout his lifetime although what religion he followed has been the subject of debate.", "As a young man, he produced a manuscript titled \"Why I have discarded evolution\", causing some scholars to describe him as a devout Methodist, who was impressed with fundamentalism, and perhaps supportive of creationism.", "However, throughout his life Whorf's main religious interest was theosophy, a nonsectarian organization based on Buddhist and Hindu teachings that promotes the view of the world as an interconnected whole and the unity and brotherhood of humankind \"without distinction of race, creed, sex, caste or color\".", "Some scholars have argued that the conflict between spiritual and scientific inclinations has been a driving force in Whorf's intellectual development, particularly in the attraction by ideas of linguistic relativity.", "Whorf said that \"of all groups of people with whom I have come in contact, Theosophical people seem the most capable of becoming excited about ideas—new ideas.", "\"Around 1924, Whorf first became interested in linguistics.", "Originally, he analyzed Biblical texts, seeking to uncover hidden layers of meaning.", "Inspired by the esoteric work ''La langue hebraïque restituée'' by Antoine Fabre d'Olivet, he began a semantic and grammatical analysis of Biblical Hebrew.", "Whorf's early manuscripts on Hebrew and Maya have been described as exhibiting a considerable degree of mysticism, as he sought to uncover esoteric meanings of glyphs and letters.=== Early studies in Mesoamerican linguistics ===Whorf studied Biblical linguistics mainly at the Watkinson Library (now Hartford Public Library).", "This library had an extensive collection of materials about Native American linguistics and folklore, originally collected by James Hammond Trumbull.", "It was at the Watkinson library that Whorf became friends with the young boy, John B. Carroll, who later went on to study psychology under B. F. Skinner, and who in 1956 edited and published a selection of Whorf's essays as ''Language, Thought and Reality'' .", "The collection rekindled Whorf's interest in Mesoamerican antiquity.", "He began studying the Nahuatl language in 1925, and later, beginning in 1928, he studied the collections of Maya hieroglyphic texts.", "Quickly becoming conversant with the materials, he began a scholarly dialog with Mesoamericanists such as Alfred Tozzer, the Maya archaeologist at Harvard University, and Herbert Spinden of the Brooklyn Museum.In 1928, he first presented a paper at the International Congress of Americanists in which he presented his translation of a Nahuatl document held at the Peabody Museum at Harvard.", "He also began to study the comparative linguistics of the Uto-Aztecan language family, which Edward Sapir had recently demonstrated to be a linguistic family.", "In addition to Nahuatl, Whorf studied the Piman and Tepecano languages, while in close correspondence with linguist J. Alden Mason.=== Field studies in Mexico ===Because of the promise shown by his work on Uto-Aztecan, Tozzer and Spinden advised Whorf to apply for a grant with the Social Science Research Council (SSRC) to support his research.", "Whorf considered using the money to travel to Mexico to procure Aztec manuscripts for the Watkinson library, but Tozzer suggested he spend the time in Mexico documenting modern Nahuatl dialects.", "In his application Whorf proposed to establish the oligosynthetic nature of the Nahuatl language.", "Before leaving Whorf presented the paper \"Stem series in Maya\" at the Linguistic Society of America conference, in which he argued that in the Mayan languages syllables carry symbolic content.", "The SSRC awarded Whorf the grant and in 1930 he traveled to Mexico City, where Professor Robert H. Barlow put him in contact with several speakers of Nahuatl to serve as his informants.", "The outcome of the trip to Mexico was Whorf's sketch of Milpa Alta Nahuatl, published only after his death, and an article on a series of Aztec pictograms found at the Tepozteco monument at Tepoztlán, Morelos in which he noted similarities in form and meaning between Aztec and Maya day signs.=== At Yale === Edward Sapir, Whorf's mentor in linguistics at YaleAlthough Whorf had been entirely an autodidact in linguistic theory and field methodology up to this point, he had already made a name for himself in Mesoamerican linguistics.", "Whorf had met Sapir, the leading US linguist of the day, at professional conferences, and in 1931 Sapir came to Yale from the University of Chicago to take a position as Professor of Anthropology.", "Alfred Tozzer sent Sapir a copy of Whorf's paper on \"Nahuatl tones and saltillo\".", "Sapir replied stating that it \"should by all means be published\"; however, it was not until 1993 that it was prepared for publication by Lyle Campbell and Frances Karttunen.Whorf took Sapir's first course at Yale on \"American Indian Linguistics\".", "He enrolled in a program of graduate studies, nominally working towards a PhD in linguistics, but he never actually attempted to obtain a degree, satisfying himself with participating in the intellectual community around Sapir.", "At Yale, Whorf joined the circle of Sapir's students that included such luminaries as Morris Swadesh, Mary Haas, Harry Hoijer, G. L. Trager and Charles F. Voegelin.", "Whorf took on a central role among Sapir's students and was well respected.Sapir had a profound influence on Whorf's thinking.", "Sapir's earliest writings had espoused views of the relation between thought and language stemming from the Humboldtian tradition he acquired through Franz Boas, which regarded language as the historical embodiment of ''volksgeist'', or ethnic world view.", "But Sapir had since become influenced by a current of logical positivism, such as that of Bertrand Russell and the early Ludwig Wittgenstein, particularly through Ogden and Richards' ''The Meaning of Meaning'', from which he adopted the view that natural language potentially obscures, rather than facilitates, the mind to perceive and describe the world as it really is.", "In this view, proper perception could only be accomplished through formal logics.", "During his stay at Yale, Whorf acquired this current of thought partly from Sapir and partly through his own readings of Russell and Ogden and Richards.", "As Whorf became more influenced by positivist science he also distanced himself from some approaches to language and meaning that he saw as lacking in rigor and insight.", "One of these was Polish philosopher Alfred Korzybski's General semantics, which was espoused in the US by Stuart Chase.", "Chase admired Whorf's work and frequently sought out a reluctant Whorf, who considered Chase to be \"utterly incompetent by training and background to handle such a subject.\"", "Ironically, Chase would later write the foreword for Carroll's collection of Whorf's writings.==== Work on Hopi and descriptive linguistics ====Sapir also encouraged Whorf to continue his work on the historical and descriptive linguistics of Uto-Aztecan.", "Whorf published several articles on that topic in this period, some of them with G. L. Trager, who had become his close friend.", "Whorf took a special interest in the Hopi language and started working with Ernest Naquayouma, a speaker of Hopi from Toreva village living in Manhattan, New York.", "Whorf credited Naquayouma as the source of most of his information on the Hopi language, although in 1938 he took a short field trip to the village of Mishongnovi, on the Second Mesa of the Hopi Reservation in Arizona.In 1936, Whorf was appointed honorary research fellow in anthropology at Yale, and he was invited by Franz Boas to serve on the committee of the Society of American Linguistics (later Linguistic Society of America).", "In 1937, Yale awarded him the Sterling Fellowship.", "He was a lecturer in anthropology from 1937 through 1938, replacing Sapir, who was gravely ill. Whorf gave graduate level lectures on \"Problems of American Indian Linguistics\".", "In 1938 with Trager's assistance he elaborated a report on the progress of linguistic research at the department of anthropology at Yale.", "The report includes some of Whorf's influential contributions to linguistic theory, such as the concept of the allophone and of covert grammatical categories.", "has argued, that in this report Whorf's linguistic theories exist in a condensed form, and that it was mainly through this report that Whorf exerted influence on the discipline of descriptive linguistics.==== Final years ====In late 1938, Whorf's own health declined.", "After an operation for cancer, he fell into an unproductive period.", "He was also deeply affected by Sapir's death in early 1939.It was in the writings of his last two years that he laid out the research program of linguistic relativity.", "His 1939 memorial article for Sapir, \"The Relation of Habitual Thought And Behavior to Language\", in particular has been taken to be Whorf's definitive statement of the issue, and is his most frequently quoted piece.In his last year Whorf also published three articles in the ''MIT Technology Review'' titled \"Science and Linguistics\", \"Linguistics as an Exact Science\" and \"Language and Logic\".", "He was also invited to contribute an article to a theosophical journal, ''Theosophist'', published in Madras, India, for which he wrote \"Language, Mind and Reality\".", "In these final pieces, he offered a critique of Western science in which he suggested that non-European languages often referred to physical phenomena in ways that more directly reflected aspects of reality than many European languages, and that science ought to pay attention to the effects of linguistic categorization in its efforts to describe the physical world.", "He particularly criticized the Indo-European languages for promoting a mistaken essentialist world view, which had been disproved by advances in the sciences, whereas he suggested that other languages dedicated more attention to processes and dynamics rather than stable essences.", "Whorf argued that paying attention to how other physical phenomena are described in the study of linguistics could make valuable contributions to science by pointing out the ways in which certain assumptions about reality are implicit in the structure of language itself, and how language guides the attention of speakers towards certain phenomena in the world which risk becoming overemphasized while leaving other phenomena at risk of being overlooked." ], [ "Posthumous reception and legacy", "At Whorf's death, his friend G. L. Trager was appointed as curator of his unpublished manuscripts.", "Some of them were published in the years after his death by another of Whorf's friends, Harry Hoijer.", "In the decade following, Trager and particularly Hoijer did much to popularize Whorf's ideas about linguistic relativity, and it was Hoijer who coined the term \"Sapir–Whorf hypothesis\" at a 1954 conference.", "Trager then published an article titled \"The systematization of the Whorf hypothesis\", which contributed to the idea that Whorf had proposed a hypothesis that should be the basis for a program of empirical research.", "Hoijer also published studies of Indigenous languages and cultures of the American South West in which Whorf found correspondences between cultural patterns and linguistic ones.", "The term, even though technically a misnomer, went on to become the most widely known label for Whorf's ideas.", "According to John A. Lucy, \"Whorf's work in linguistics was and still is recognized as being of superb professional quality by linguists\".=== Universalism and anti-Whorfianism ===Whorf's work began to fall out of favor less than a decade after his death, and he was subjected to severe criticism from scholars of language, culture and psychology.", "In 1953 and 1954, psychologists Roger Brown and Eric Lenneberg criticized Whorf for his reliance on anecdotal evidence, formulating a hypothesis to scientifically test his ideas, which they limited to an examination of a causal relation between grammatical or lexical structure and cognition or perception.", "Whorf himself did not advocate a straight causality between language and thought; instead he wrote that \"Language and culture had grown up together\"; that both were mutually shaped by the other.", "Hence, has argued that because the aim of the formulation of the Sapir–Whorf hypothesis was to test simple causation, it failed to test Whorf's ideas from the outset.Focusing on color terminology, with easily discernible differences between perception and vocabulary, Brown and Lenneberg published in 1954 a study of Zuni color terms that slightly support a weak effect of semantic categorization of color terms on color perception.", "In doing so they began a line of empirical studies that investigated the principle of linguistic relativity.Empirical testing of the Whorfian hypothesis declined in the 1960s to 1980s as Noam Chomsky began to redefine linguistics and much of psychology in formal universalist terms.", "Several studies from that period refuted Whorf's hypothesis, demonstrating that linguistic diversity is a surface veneer that masks underlying universal cognitive principles.", "Many studies were highly critical and disparaging in their language, ridiculing Whorf's analyses and examples or his lack of an academic degree.", "Throughout the 1980s, most mentions of Whorf or of the Sapir–Whorf hypotheses continued to be disparaging, and led to a widespread view that Whorf's ideas had been proven wrong.", "Because Whorf was treated so severely in the scholarship during those decades, he has been described as \"one of the prime whipping boys of introductory texts to linguistics\".", "With the advent of cognitive linguistics and psycholinguistics in the late 1980s, some linguists sought to rehabilitate Whorf's reputation, as scholarship began to question whether earlier critiques of Whorf were justified.By the 1960s, analytical philosophers also became aware of the Sapir–Whorf hypothesis, and philosophers such as Max Black and Donald Davidson published scathing critiques of Whorf's strong relativist viewpoints.", "Black characterized Whorf's ideas about metaphysics as demonstrating \"amateurish crudity\".", "According to Black and Davidson, Whorf's viewpoint and the concept of linguistic relativity meant that translation between languages with different conceptual schemes would be impossible.", "Recent assessments such as those by Leavitt and Lee, however, consider Black and Davidson's interpretation to be based on an inaccurate characterization of Whorf's viewpoint, and even rather absurd given the time he spent trying to translate between different conceptual schemes.", "In their view, the critiques are based on a lack of familiarity with Whorf's writings; according to these recent Whorf scholars a more accurate description of his viewpoint is that he thought translation to be possible, but only through careful attention to the subtle differences between conceptual schemes.Eric Lenneberg, Noam Chomsky, and Steven Pinker have also criticized Whorf for failing to be sufficiently clear in his formulation of how language influences thought, and for failing to provide real evidence to support his assumptions.", "Generally Whorf's arguments took the form of examples that were anecdotal or speculative, and functioned as attempts to show how \"exotic\" grammatical traits were connected to what were considered equally exotic worlds of thought.", "Even Whorf's defenders admitted that his writing style was often convoluted and couched in neologisms – attributed to his awareness of language use, and his reluctance to use terminology that might have pre-existing connotations.", "argues that Whorf was mesmerized by the foreignness of indigenous languages, and exaggerated and idealized them.", "According to Lakoff, Whorf's tendency to exoticize data must be judged in the historical context: Whorf and the other Boasians wrote at a time in which racism and jingoism were predominant, and when it was unthinkable to many that \"savages\" had redeeming qualities, or that their languages were comparable in complexity to those of Europe.", "For this alone Lakoff argues, Whorf can be considered to be \"Not just a pioneer in linguistics, but a pioneer as a human being\".Today many followers of universalist schools of thought continue to oppose the idea of linguistic relativity, seeing it as unsound or even ridiculous.", "For example, Steven Pinker argues in his book ''The Language Instinct'' that thought exists prior to language and independently of it, a view also espoused by philosophers of language such as Jerry Fodor, John Locke and Plato.", "In this interpretation, language is inconsequential to human thought because humans do not think in \"natural\" language, i.e.", "any language used for communication.", "Rather, we think in a meta-language that precedes natural language, which Pinker following Fodor calls \"mentalese.\"", "Pinker attacks what he calls \"Whorf's radical position\", declaring, \"the more you examine Whorf's arguments, the less sense they make.\"", "Scholars of a more \"relativist\" bent such as John A. Lucy and Stephen C. Levinson have criticized Pinker for misrepresenting Whorf's views and arguing against strawmen.=== Resurgence of Whorfianism ===Linguistic relativity studies have experienced a resurgence since the 1990s, and a series of favorable experimental results have brought Whorfianism back into favor, especially in cultural psychology and linguistic anthropology.", "The first study directing positive attention towards Whorf's relativist position was George Lakoff's \"Women, Fire and Dangerous Things\", in which he argued that Whorf had been on the right track in his focus on differences in grammatical and lexical categories as a source of differences in conceptualization.", "In 1992 psychologist John A. Lucy published two books on the topic, one analyzing the intellectual genealogy of the hypothesis, arguing that previous studies had failed to appreciate the subtleties of Whorf's thinking; they had been unable to formulate a research agenda that would actually test Whorf's claims.", "Lucy proposed a new research design so that the hypothesis of linguistic relativity could be tested empirically, and to avoid the pitfalls of earlier studies which Lucy claimed had tended to presuppose the universality of the categories they were studying.", "His second book was an empirical study of the relation between grammatical categories and cognition in the Yucatec Maya language of Mexico.In 1996 Penny Lee's reappraisal of Whorf's writings was published, reinstating Whorf as a serious and capable thinker.", "Lee argued that previous explorations of the Sapir–Whorf hypothesis had largely ignored Whorf's actual writings, and consequently asked questions very unlike those Whorf had asked.", "Also in that year a volume, \"Rethinking Linguistic Relativity\" edited by John J. Gumperz and Stephen C. Levinson gathered a range of researchers working in psycholinguistics, sociolinguistics and linguistic anthropology to bring renewed attention to the issue of how Whorf's theories could be updated, and a subsequent review of the new direction of the linguistic relativity paradigm cemented the development.", "Since then considerable empirical research into linguistic relativity has been carried out, especially at the Max Planck Institute for Psycholinguistics with scholarship motivating two edited volumes of linguistic relativity studies, and in American Institutions by scholars such as Lera Boroditsky and Dedre Gentner.In turn universalist scholars frequently dismiss as \"dull\" or \"boring\", positive findings of influence of linguistic categories on thought or behavior, which are often subtle rather than spectacular, suggesting that Whorf's excitement about linguistic relativity had promised more spectacular findings than it was able to provide.Whorf's views have been compared to those of philosophers such as Friedrich Nietzsche and the late Ludwig Wittgenstein, both of whom considered language to have important bearing on thought and reasoning.", "His hypotheses have also been compared to the views of psychologists such as Lev Vygotsky, whose social constructivism considers the cognitive development of children to be mediated by the social use of language.", "Vygotsky shared Whorf's interest in gestalt psychology, and he also read Sapir's works.", "Others have seen similarities between Whorf's work and the ideas of literary theorist Mikhail Bakhtin, who read Whorf and whose approach to textual meaning was similarly holistic and relativistic.", "Whorf's ideas have also been interpreted as a radical critique of positivist science." ], [ "Work", "=== Linguistic relativity ===Whorf is best known as the main proponent of what he called the principle of linguistic relativity, but which is often known as \"the Sapir–Whorf hypothesis\", named for him and Edward Sapir.", "Whorf never stated the principle in the form of a hypothesis, and the idea that linguistic categories influence perception and cognition was shared by many other scholars before him.", "But because Whorf, in his articles, gave specific examples of how he saw the grammatical categories of specific languages related to conceptual and behavioral patterns, he pointed towards an empirical research program that has been taken up by subsequent scholars, and which is often called \"Sapir–Whorf studies\".==== Sources of influence on Whorf's thinking ====Whorf's illustration of the difference between the English and Shawnee gestalt construction of cleaning a gun with a ramrod.", "From the article \"Language and Science\", originally published in the MIT technology Review, 1940.Image copyright of MIT Press.Whorf and Sapir both drew explicitly on Albert Einstein's principle of general relativity; hence linguistic relativity refers to the concept of grammatical and semantic categories of a specific language providing a frame of reference as a medium through which observations are made.", "Following an original observation by Boas, Sapir demonstrated that speakers of a given language perceive sounds that are acoustically different as the same, if the sound comes from the underlying phoneme and does not contribute to changes in semantic meaning.", "Furthermore, speakers of languages are attentive to sounds, particularly if the same two sounds come from different phonemes.", "Such differentiation is an example of how various observational frames of reference leads to different patterns of attention and perception.Whorf was also influenced by gestalt psychology, believing that languages require their speakers to describe the same events as different gestalt constructions, which he called \"isolates from experience\".", "An example is how the action of cleaning a gun is different in English and Shawnee: English focuses on the instrumental relation between two objects and the purpose of the action (removing dirt); whereas the Shawnee language focuses on the movement—using an arm to create a dry space in a hole.", "The event described is the same, but the attention in terms of figure and ground are different.==== Degree of influence of language on thought ====If read superficially, some of Whorf's statements lend themselves to the interpretation that he supported linguistic determinism.", "For example, in an often-quoted passage Whorf writes:The statements about the obligatory nature of the terms of language have been taken to suggest that Whorf meant that language completely determined the scope of possible conceptualizations.", "However neo-Whorfians argue that here Whorf is writing about the terms in which we speak of the world, not the terms in which we think of it.", "Whorf noted that to communicate thoughts and experiences with members of a speech community speakers must use the linguistic categories of their shared language, which requires moulding experiences into the shape of language to speak them—a process called \"thinking for speaking\".", "This interpretation is supported by Whorf's subsequent statement that \"No individual is free to describe nature with absolute impartiality, but is constrained by certain modes of interpretation even when he thinks himself most free\".", "Similarly the statement that observers are led to different pictures of the universe has been understood as an argument that different conceptualizations are incommensurable making translation between different conceptual and linguistic systems impossible.", "Neo-Whorfians argue this to be a misreading since throughout his work one of his main points was that such systems could be \"calibrated\" and thereby be made commensurable, but only when we become aware of the differences in conceptual schemes through linguistic analysis.==== Hopi time ====Whorf's study of Hopi time has been the most widely discussed and criticized example of linguistic relativity.", "In his analysis he argues that there is a relation between how the Hopi people conceptualize time, how they speak of temporal relations, and the grammar of the Hopi language.", "Whorf's most elaborate argument for the existence of linguistic relativity was based on what he saw as a fundamental difference in the understanding of time as a conceptual category among the Hopi.", "He argued that the Hopi language, in contrast to English and other SAE languages, does not treat the flow of time as a sequence of distinct countable instances, like \"three days\" or \"five years\", but rather as a single process.", "Because of this difference, the language lacks nouns that refer to units of time.", "He proposed that the Hopi view of time was fundamental in all aspects of their culture and furthermore explained certain patterns of behavior.", "In his 1939 memorial essay to Sapir he wrote that \"... the Hopi language is seen to contain no words, grammatical forms, construction or expressions that refer directly to what we call 'time', or to past, present, or future...\"Linguist Ekkehart Malotki challenged Whorf's analyses of Hopi temporal expressions and concepts with numerous examples how the Hopi language refers to time.", "Malotki argues that in the Hopi language the system of tenses consists of future and non-future and that the single difference between the three-tense system of European languages and the Hopi system, is that the latter combines past and present to form a single category.Malotki's critique was widely cited as the final piece of evidence in refuting Whorf's ideas and his concept of linguistic relativity while other scholars defended the analysis of Hopi, arguing that Whorf's claim was not that Hopi lacked words or categories to describe temporality, but that the Hopi concept of time is altogether different from that of English speakers.", "Whorf described the Hopi categories of tense, noting that time is not divided into past, present and future, as is common in European languages, but rather a single tense refers to both present and past while another refers to events that have not yet happened and may or may not happen in the future.", "He also described a large array of stems that he called \"tensors\" which describes aspects of temporality, but without referring to countable units of time as in English and most European languages.=== Contributions to linguistic theory ===Whorf's distinction between \"overt\" (phenotypical) and \"covert\" (cryptotypical) grammatical categories has become widely influential in linguistics and anthropology.", "British linguist Michael Halliday wrote about Whorf's notion of the \"cryptotype\", and the conception of \"how grammar models reality\", that it would \"eventually turn out to be among the major contributions of twentieth century linguistics\".Furthermore, Whorf introduced the concept of the allophone, a word that describes positional phonetic variants of a single superordinate phoneme; in doing so he placed a cornerstone in consolidating early phoneme theory.", "The term was popularized by G. L. Trager and Bernard Bloch in a 1941 paper on English phonology and went on to become part of standard usage within the American structuralist tradition.", "Whorf considered allophones to be another example of linguistic relativity.", "The principle of allophony describes how acoustically different sounds can be treated as reflections of a single phoneme in a language.", "This sometimes makes the different sound appear similar to native speakers of the language, even to the point that they are unable to distinguish them auditorily without special training.", "Whorf wrote that: \"allophones are also relativistic.", "Objectively, acoustically, and physiologically the allophones of a phoneme may be extremely unlike, hence the impossibility of determining what is what.", "You always have to keep the observer in the picture.", "What linguistic pattern makes like is like, and what it makes unlike is unlike\".", "(Whorf, 1940)Central to Whorf's inquiries was the approach later described as metalinguistics by G. L. Trager, who in 1950 published four of Whorf's essays as \"Four articles on Metalinguistics\".", "Whorf was crucially interested in the ways in which speakers come to be aware of the language that they use, and become able to describe and analyze language using language itself to do so.", "Whorf saw that the ability to arrive at progressively more accurate descriptions of the world hinged partly on the ability to construct a metalanguage to describe how language affects experience, and thus to have the ability to calibrate different conceptual schemes.", "Whorf's endeavors have since been taken up in the development of the study of metalinguistics and metalinguistic awareness, first by Michael Silverstein who published a radical and influential rereading of Whorf in 1979 and subsequently in the field of linguistic anthropology.=== Studies of Uto-Aztecan languages ===Whorf conducted important work on the Uto-Aztecan languages, which Sapir had conclusively demonstrated as a valid language family in 1915.Working first on Nahuatl, Tepecano, Tohono O'odham he established familiarity with the language group before he met Sapir in 1928.During Whorf's time at Yale he published several articles on Uto-Aztecan linguistics, such as \"Notes on the Tübatulabal language\".", "In 1935 he published \"The Comparative Linguistics of Uto-Aztecan\", and a review of Kroeber's survey of Uto-Aztecan linguistics.", "Whorf's work served to further cement the foundations of the comparative Uto-Aztecan studies.The first Native American language Whorf studied was the Uto-Aztecan language Nahuatl which he studied first from colonial grammars and documents, and later became the subject of his first field work experience in 1930.Based on his studies of Classical Nahuatl Whorf argued that Nahuatl was an oligosynthetic language, a typological category that he invented.", "In Mexico working with native speakers, he studied the dialects of Milpa Alta and Tepoztlán.", "His grammar sketch of the Milpa Alta dialect of Nahuatl was not published during his lifetime, but it was published posthumously by Harry Hoijer and became quite influential and used as the basic description of \"Modern Nahuatl\" by many scholars.", "The description of the dialect is quite condensed and in some places difficult to understand because of Whorf's propensity of inventing his own unique terminology for grammatical concepts, but the work has generally been considered to be technically advanced.", "He also produced an analysis of the prosody of these dialects which he related to the history of the glottal stop and vowel length in Nahuan languages.", "This work was prepared for publication by Lyle Campbell and Frances Karttunen in 1993, who also considered it a valuable description of the two endangered dialects, and the only one of its kind to include detailed phonetic analysis of supra-segmental phenomena.In Uto-Aztecan linguistics one of Whorf's achievements was to determine the reason the Nahuatl language has the phoneme , not found in the other languages of the family.", "The existence of in Nahuatl had puzzled previous linguists and caused Sapir to reconstruct a phoneme for proto-Uto-Aztecan based only on evidence from Aztecan.", "In a 1937 paper published in the journal ''American Anthropologist'', Whorf argued that the phoneme resulted from some of the Nahuan or Aztecan languages having undergone a sound change from the original * to in the position before *.", "This sound law is known as \"Whorf's law\", considered valid although a more detailed understanding of the precise conditions under which it took place has since been developed.Also in 1937, Whorf and his friend G. L. Trager, published a paper in which they elaborated on the Azteco-Tanoan language family, proposed originally by Sapir as a family comprising the Uto-Aztecan and the Kiowa-Tanoan languages—(the Tewa and Kiowa languages).=== Maya epigraphy ===In a series of published and unpublished studies in the 1930s, Whorf argued that Mayan writing was to some extent phonetic.", "While his work on deciphering the Maya script gained some support from Alfred Tozzer at Harvard, the main authority on Ancient Maya culture, J. E. S. Thompson, strongly rejected Whorf's ideas, saying that Mayan writing lacked a phonetic component and is therefore impossible to decipher based on a linguistic analysis.", "Whorf argued that it was exactly the reluctance to apply linguistic analysis of Maya languages that had held the decipherment back.", "Whorf sought for cues to phonetic values within the elements of the specific signs, and never realized that the system was logo-syllabic.", "Although Whorf's approach to understanding the Maya script is now known to have been misguided, his central claim that the script was phonetic and should be deciphered as such was vindicated by Yuri Knorozov's syllabic decipherment of Mayan writing in the 1950s." ], [ "Notes", "===Commentary notes===" ], [ "References" ], [ "Sources", "* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *" ], [ "External links", "* B.
