Toyota A Engine
The Toyota A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads. To make the engine as short as possible, the cylinders are siamesed. The development of the series began in the late 1970s, when Toyota wanted to develop a completely new engine for the Toyota Tercel, the successor of Toyota's K engine. The goal was to achieve good fuel efficiency and performance as well as low emissions with a modern design. The A-series includes one of the first Japanese mass-production DOHC, four-valve-per-cylinder engines, the 4A-GE, and a later version of the same engine was one of the first production five-valve-per-cylinder engines. Toyota joint venture partner Tianjin FAW Xiali produces the 1.3 L 8A and resumed production of the 5A in 2007. 1A The 1.5 L 1A was produced between 1978 and ...

4A Centre For Contemporary Asian Art
4A Centre for Contemporary Asian Art, formerly known as Gallery 4A, 4A Galleries, Asia-Australia Arts Centre and also known simply as 4A, is an Australian independent not-for-profit organisation based in the Haymarket area of Sydney, New South Wales. It commissions, exhibits, documents and researches Asian and Asian-Australian contemporary art in Australia, and promotes Australian talent in Asia, promoting and maintaining cultural connections between the nation and the region. The gallery and the associated Performance 4A (for the performing arts) were founded by the Asian Australian Artists Association Inc. in 1997. The centre is funded mainly by Commonwealth, state and local government sources, but also by private sponsors and organisations, and generates its own income. It has partnered with the Sydney Biennale twice, as well as other organisations such as the Campbelltown Arts Centre to mount major exhibitions and events. History 4A began in 1995 when a group of artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TI-99/4A
The TI-99/4 and TI-99/4A are home computers released by Texas Instruments (TI) in 1979 and 1981, respectively. Based on TI's own TMS9900 microprocessor originally used in minicomputers, the TI-99/4 was the first 16-bit home computer. The associated TMS9918 video display controller provides color graphics and Sprite (computer graphics), sprite support which were only comparable with those of the Atari 8-bit computers, Atari 400 and 800 released a month later. The TI-99 series also initially competed with the Apple II and TRS-80."Death of a Computer," April 1984, ''Texas Monthly,'' retrieved September 20, 2023 The calculator-style keyboard of the TI-99/4 and the high price were cited as weak points. TI's reliance on ROM cartridges and their practice of limiting develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4A Engine
4A Games Limited is a Ukrainian-Maltese video game developer based in Sliema, Malta. The company was founded in Kyiv, Ukraine, in 2006 by three developers who departed from GSC Game World. In 2014, 4A Games moved its headquarters to Sliema, wherein one Kyiv office was retained as a sub-studio (which became independent and was rebranded in 2025 as Reburn). The company is best known for developing the ''Metro'' video game series. History Foundation 4A Games was founded by former developers from GSC Game World: Andrew Prokhorov, Oles Shyshkovtsov, and Alexander Maximchuk; they, together with Sergei Karmalsky, formed the core team of '' S.T.A.L.K.E.R.: Shadow of Chernobyl'', which was in development at GSC in the early and mid-2000s. Prokhorov had disliked that Sergiy Grygorovych, the chief executive officer (CEO) of GSC, prioritized money over his employees, withholding royalties for games the company had produced. The situation came to a high point when the two fell out over w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Associated Actors And Artistes Of America
The Associated Actors and Artistes of America (4As), established in 1919, is the federation of trade unions for performing artists in the United States. Gary M. Fink, ed. ''Labor unions'' (Greenwood, 1977) pp. 3-4. The union was established by the merger of the Actors' Equity Association and the White Rats of America. By the mid-1940s, its affiliates were: * Actors' Equity Association * American Federation of Radio Artists * American Guild of Musical Artists * American Guild of Variety Artists * Brother Artists Association * Chorus Equity Association * Hebrew Chorus Union * Hungarian Actors' and Artists' Association * Screen Actors' Guild As of 2022, the following unions belong to the 4As: * The Actors' Equity Association (AEA) * The American Guild of Musical Artists (AGMA) * The American Guild of Variety Artists (AGVA) * The Guild of Italian American Actors (GIAA) also known as Italian Actors' Union * The Screen Actors Guild-American Federation of Television and R ...

4A/OP
4A/OP or, Automatized Atmospheric Absorption Atlas, is an operational fast and accurate radiative transfer model for the infrared. 4A/OP is a user-friendly software for various scientific applications (surface, balloon or space-based observations), co-developed by LMD ( Laboratoire de Meteorologie Dynamique) and NOVELTIS with the support of CNES (the French Space Agency). NOVELTIS is in charge of the industrialization and the distribution of the LMD 4A radiative transfer model. 4A allows fast and accurate computation of transmittance and radiance, owing to the use of a comprehensive database (atlases) of monochromatic optical thicknesses for up to 43 atmospheric molecular species. Precomputed once and for all, the atlases are created by using the line-by-line and layer-by-layer model, STRANSAC, with up to date physics. Owing to the computation of Jacobians (partial derivatives of the radiance with respect to atmospheric variables), the 4A model can be easily coupled with an inver ...

Vermont Route 4A
Vermont Route 4A (VT 4A) is a east–west state highway in Rutland County, Vermont, United States. It runs from Fair Haven to West Rutland.

Long March 4A
The Long March 4A (), also known as the Changzheng 4A, CZ-4A and LM-4A, sometimes misidentified as the Long March 4 due to the lack of any such designated rocket, was a Chinese orbital carrier rocket. It was launched from Launch Area 7 at the Taiyuan Satellite Launch Center. It was a three-stage rocket, used for two launches in 1988 and 1990. On its maiden flight, on 6 September 1988, it placed the FY-1A weather satellite into orbit. On its second, and final, flight it launched another weather satellite, FY-1B. A month after the launch of FY-1B, the third-stage of the CZ-4A launch vehicle exploded in a 895 x 880 km orbit, creating more than 100 pieces of space debris. This incident led to a redesign of the rocket to include a residual propellant venting system. A venting system was not included in the 4A because of the concern that it would damage the satellite. It was replaced by a derivative, the Long March 4B The Long March 4B (), also known as the Chang Zheng 4B, CZ-4B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Sieve
A molecular sieve is a material with pores of uniform size comparable to that of individual molecules, linking the interior of the solid to its exterior. These materials embody the molecular sieve effect, in which molecules larger than the pores are preferentially sieved, allowing for the selective adsorption of specific compounds based on their molecular size. Many kinds of materials exhibit some molecular sieves, but zeolites dominate the field. Zeolites are almost always aluminosilicates, or variants where some or all of the Si or Al centers are replaced by similarly charged elements. Sieving process The diameters of the pores that comprise molecular sieves are similar in size to small molecules. Large molecules cannot enter or be adsorbed, while smaller molecules can. As a mixture of molecules migrates through the stationary bed of porous, semi-solid substance referred to as a sieve (or matrix), the components of the highest molecular weight (which are unable to pass int ...
