African Union
The African Union (AU) is a continental union consisting of 55 member states located on the continent of Africa. The AU was announced in the Sirte Declaration in Sirte, Libya, on 9 September 1999, calling for the establishment of the African Union. The bloc was founded on 26 May 2001 in Addis Ababa, Ethiopia, and launched on 9 July 2002 in Durban, South Africa. The intention of the AU was to replace the Organisation of African Unity (OAU), established on 25 May 1963 in Addis Ababa by 32 signatory governments; the OAU was disbanded on 9 July 2002. The most important decisions of the AU are made by the Assembly of the African Union, a semi-annual meeting of the heads of state and government of its member states. The AU's secretariat, the African Union Commission, is based in Addis Ababa. The largest city in the AU is Lagos, Nigeria, while the largest urban agglomeration is Cairo, Egypt. The African Union has more than 1.3 billion people and an area of around and includes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Astronomical Unit
The astronomical unit (symbol: au, or or AU) is a unit of length, roughly the distance from Earth to the Sun and approximately equal to or 8.3 light-minutes. The actual distance from Earth to the Sun varies by about 3% as Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once each year. The astronomical unit was originally conceived as the average of Earth's aphelion and perihelion; however, since 2012 it has been defined as exactly (see below for several conversions). The astronomical unit is used primarily for measuring distances within the Solar System or around other stars. It is also a fundamental component in the definition of another unit of astronomical length, the parsec. History of symbol usage A variety of unit symbols and abbreviations have been in use for the astronomical unit. In a 1976 resolution, the International Astronomical Union (IAU) had used the symbol ''A'' to denote a length equal to the astronomical ...

Adobe Audition
Adobe Audition is a digital audio workstation developed by Adobe Inc. featuring both a multitrack, non-destructive mix/edit environment and a destructive-approach waveform editing view. Origins Syntrillium Software was founded in the early 1990s by Robert Ellison and David Johnston, both former Microsoft employees. Originally developed by Syntrillium as Cool Edit, the program was distributed as crippleware for Windows computers. The full version was useful and flexible, particularly for its time. Syntrillium later released Cool Edit Pro, which added the capability to work with multiple tracks as well as other features. Audio processing, however, was done in a destructive manner (at the time, most computers were not powerful enough in terms of processor performance and memory capacity to perform non-destructive operations in real-time). Cool Edit Pro v2 added support for real-time non-destructive processing, and v2.1 added support for surround sound mixing and unlimited simulta ...

Christopher Hewitt Award
The Christopher Hewitt Award is an annual literary award given each June by ''A&U'' magazine for writing that addresses or relates to HIV/AIDS. One award is given in each of four categories: fiction, poetry, creative nonfiction, and drama. Awards were first given in 2013. The winners for 2013 were Lisa Sandlin (fiction), Dorothy Alexander (poetry), Terry Dugan (creative nonfiction), and Evan Guilford-Blake (drama). ''A&U'' (originally, ''Art & Understanding'') was established in 1991 as a response to the ongoing loss of members of the creative community due to HIV/AIDS and as a forum for documenting their work. Today, the nonprofit magazine focuses on a variety of aspects of the global pandemic—including advocacy, prevention, and care—in addition to literature and the arts. Notable artists, activists, and writers are interviewed and featured in each issue. Examples include Anjelica Huston, Janet Jackson, Tony Kushner, George Takei, and Lupe Ontiveros. The award was initiated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Update
Windows Update is a Microsoft service for the Windows 9x and Windows NT families of operating system, which automates downloading and installing Microsoft Windows software updates over the Internet. The service delivers software updates for Windows, as well as the various Microsoft Antivirus software, antivirus products, including Windows Defender and Microsoft Security Essentials. Since its inception, Microsoft has introduced two extensions of the service: Microsoft Update and Windows Update for Business. The former expands the core service to include other Microsoft products, such as Microsoft Office and Microsoft Expression Studio. The latter is available to business editions of Windows 10 and permits postponing updates or receiving updates only after they have undergone rigorous testing. As the service has evolved over the years, so has its client software. For a decade, the primary client component of the service was the Windows Update web app that could only be run on Inter ...
