Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Aerolíneas Argentinas
Aerolíneas Argentinas, formally Aerolíneas Argentinas S.A., is Argentina's largest airline and the country flag carrier. The airline was created in 1949 from the merger of four companies and started operations in . A consortium led by Iberia took control of the airline in 1990, and Grupo Marsans acquired the company and its subsidiaries in 2001, following a period of severe financial difficulties that put the airline on the brink of closure. The company has been run by the Argentine government since late 2008, when the country regained control of the airline after it was taken over from the Spanish owners. , Aerolíneas Argentinas was state-owned. It has its headquarters in Buenos Aires. SkyTeam membership was achieved in late ; the airline's cargo division became a member of SkyTeam Cargo in . Aerolíneas Argentinas and its former sister company Austral Líneas Aéreas operates from two hubs, both located in Buenos Aires: Aeroparque Jorge Newbery and Ministro Pistarini Int ...

Arginine
Arginine is the amino acid with the formula (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H. The molecule features a guanidino group appended to a standard amino acid framework. At physiological pH, the carboxylic acid is deprotonated (−CO2−) and both the amino and guanidino groups are protonated, resulting in a cation. Only the -arginine (symbol Arg or R) enantiomer is found naturally. Arg residues are common components of proteins. It is encoded by the codons CGU, CGC, CGA, CGG, AGA, and AGG. The guanidine group in arginine is the precursor for the biosynthesis of nitric oxide. Like all amino acids, it is a white, water-soluble solid. History Arginine was first isolated in 1886 from yellow lupin seedlings by the German chemist Ernst Schulze and his assistant Ernst Steiger. He named it from the Greek ''árgyros'' (ἄργυρος) meaning "silver" due to the silver-white appearance of arginine nitrate crystals. In 1897, Schulze and Ernst Winterstein (1865–1949) determined the structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternate Reality Game
An alternate reality game (ARG) is an interactive networked narrative that uses the real world as a platform and employs transmedia storytelling to deliver a story that may be altered by players' ideas or actions. The form is defined by intense player involvement with a story that takes place in real time and evolves according to players' responses. It is shaped by characters that are actively controlled by the game's designers, as opposed to being controlled by an AI as in a computer or console video game. Players interact directly with characters in the game, solve plot-based challenges and puzzles, and collaborate as a community to analyze the story and coordinate real-life and online activities. ARGs generally use multimedia, such as telephones and mail, but rely on the Internet as the central binding medium. ARGs tend to be free to play, with costs absorbed either through supporting products (e.g., collectible puzzle cards fund Perplex City) or through promotional relatio ...

Hull Classification Symbol
The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol (sometimes called hull code or hull number) to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use. History United States Navy The U.S. Navy began to assign unique Naval Registry Identification Numbers to its ships in the 1890s. The system was a simple one in which each ship received a number which was appended to its ship type, fully spelled out, and added parenthetically after the ship's name when deemed necessary to avoid confusion between ships. Under this system, for example, the battleship ''Indiana'' was USS ''Indiana'' (Battleship No. 1), the cruiser ''Olympia'' was USS ''Olympia'' (Cruiser No. 6), and so on. Beginning in 1907, some ships also were referred to alternatively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argument (complex Analysis)
In mathematics (particularly in complex analysis), the argument of a complex number ''z'', denoted arg(''z''), is the angle between the positive real axis and the line joining the origin and ''z'', represented as a point in the complex plane, shown as \varphi in Figure 1. It is a multi-valued function operating on the nonzero complex numbers. To define a single-valued function, the principal value of the argument (sometimes denoted Arg ''z'') is used. It is often chosen to be the unique value of the argument that lies within the interval . Definition An argument of the complex number , denoted , is defined in two equivalent ways: #Geometrically, in the complex plane, as the 2D polar angle \varphi from the positive real axis to the vector representing . The numeric value is given by the angle in radians, and is positive if measured counterclockwise. #Algebraically, as any real quantity \varphi such that z = r (\cos \varphi + i \sin \varphi) = r e^ for some positive real ...

Argentine Peso
The peso (established as the ''peso convertible'') is the currency of Argentina, identified by the symbol $ preceding the amount in the same way as many countries using peso or dollar currencies. It is subdivided into 100 '' centavos''. Its ISO 4217 code is ARS. The Argentine currency has experienced severe inflation, with periods of hyperinflation, since the mid-20th century, with periodic change of the currency to a new version at a rate ranging from 100:1 to 10,000:1. The peso introduced in 1992 was worth 10,000,000,000,000 (ten trillion) of the pesos in use until 1970. Since the early 21st century, the Argentine peso has experienced a substantial rate of devaluation, reaching over 51% year-on-year inflation rate in 2021. The official exchange rate for the United States dollar commenced at 1:1 at the peso's introduction in 1992; it then hovered around 3:1 from 2002 to 2008, before climbing from 6:1 to 10:1 between 2009 and 2015. In July 2022, the value exchange rate with the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argument Of A Function
In mathematics, an argument of a function is a value provided to obtain the function's result. It is also called an independent variable. For example, the binary function f(x,y) = x^2 + y^2 has two arguments, x and y, in an ordered pair (x, y). The hypergeometric function is an example of a four-argument function. The number of arguments that a function takes is called the ''arity'' of the function. A function that takes a single argument as input, such as f(x) = x^2, is called a unary function. A function of two or more variables is considered to have a domain consisting of ordered pairs or tuples of argument values. The argument of a circular function is an angle. The argument of a hyperbolic function is a hyperbolic angle. A mathematical function has one or more arguments in the form of independent variables designated in the definition, which can also contain parameters. The independent variables are mentioned in the list of arguments that the function takes, whereas the par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arg-é Bam
The Arg-e Bam ( fa, ارگ بم), located in the city of Bam, Kerman Province of southeastern Iran, is the largest adobe building in the world. The entire building was a large fortress containing the citadel, but because the citadel dominates the ruins, the entire fortress is now named Bam Citadel. Listed by UNESCO as part of the World Heritage Site "Bam and its Cultural Landscape", it can be traced back to at least the Achaemenid Empire (sixth to fourth centuries BC). The citadel rose to importance from the seventh to eleventh centuries, as a crossroads along the Silk Road and other important trade routes, and as a producer of silk and cotton garments. On 26 December 2003, the citadel was almost completely destroyed by an earthquake, along with much of the rest of Bam and its environs. A few days after the earthquake, the President of Iran, Mohammad Khatami, announced that the citadel would be rebuilt. A brief history There is no precise archaeological dating of the bui ...

Arg Of Tabriz
Arg of Tabriz ( fa, ارگ تبريز, also known as ''Arg Alishah'', ''Arg-e Alishah'', ''Arch of Alishah'', ''Arg Citadel'', and ''Masjid Ali-Shāh''), is the remnants of a large acropolis fortification (whence the metathetic name or plus ) and city wall in downtown Tabriz, Iran. Its structure is visible from far distances in downtown Tabriz, if not blocked by the newly erected highrise buildings. The structure was initially a compound, containing a great vaulted mosque, adjoining prayer halls and libraries, a vast courtyard containing a huge reflecting pool, and a mausoleum—all surrounded by a containing wall. It was built in 14th century during the Ilkhanate era. The point of pride for the building was that its vaulted ayvan was larger than the famous historic vault of Khosrows/Kisra or the Taq Kisra at Ctesiphon/Mada'in. However, with the sudden death of the governor of the city and with some construction complications in constructing a roofed building without pilla ...
