The O2
The O2 is a large entertainment district on the Greenwich peninsula in South East London, England, including an indoor arena, a music club, a Cineworld cinema, an exhibition space, piazzas, bars, and restaurants. It was built largely within the former Millennium Dome, a large dome-shaped canopy built to house an exhibition celebrating the turn of the third millennium; consequently ''The Dome'' remains a name in common usage for the venue. It is sometimes referred to as The O2 Arena, but that name properly refers to an indoor arena within The O2. Naming rights to the district were purchased by the mobile telephone provider O2 from its developers, Anschutz Entertainment Group (AEG), during the development of the district. AEG owns the long-term lease on the O2 Arena and surrounding leisure space. From the closure of the original Millennium Experience exhibition occupying the site, several ways of reusing the Millennium Dome's shell were proposed and then rejected. The re ...

The O2 Arena
The O2 Arena, commonly known as the O2 (stylised as The O2 arena), is a multi-purpose indoor arena in the centre of the O2 entertainment complex on the Greenwich Peninsula in southeast London. It opened in its present form in 2007. It has the second-highest seating capacity of any indoor venue in the United Kingdom, behind the Manchester Arena, and in 2008 was the world's busiest music arena. As of 2022, it is the ninth-largest building in the world by volume. The arena was built under the Millennium Dome, a large dome-shaped building built to house an exhibition celebrating the turn of the third millennium; as the structure still stands over the arena, ''The Dome'' remains a name in common usage for the venue. The arena, as well as the overall O2 complex, is named after its primary sponsor, the telecommunications company O2, a subsidiary of Virgin Media O2. History Following the closure of the Millennium Experience at the end of 2000, the Millennium Dome was leased to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SGI O2
The O2 was an entry-level Unix workstation introduced in 1996 by Silicon Graphics, Inc. (SGI) to replace their earlier Indy series. Like the Indy, the O2 used a single MIPS microprocessor and was intended to be used mainly for multimedia. Its larger counterpart was the SGI Octane. The O2 was SGI's last attempt at a low-end workstation. Hardware System architecture Originally known as the "Moosehead" project, the O2 architecture featured a proprietary high-bandwidth Unified Memory Architecture (UMA) to connect system components. A PCI bus is bridged onto the UMA with one slot available. It had a designer case and an internal modular construction. Two SCSI drives could be mounted on special caddies (1 in the later R10000/R12000 models due to heat constraints) and an optional video capture / sound cassette mounted on the far left side. CPU The O2 comes in two distinct CPU flavours; the low-end MIPS 180 to 350 MHz R5000- or RM7000-based units and the higher-end 150 to 40 ...

Superoxide
In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula . The systematic name of the anion is dioxide(1−). The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen , which occurs widely in nature. Molecular oxygen (dioxygen) is a diradical containing two unpaired electrons, and superoxide results from the addition of an electron which fills one of the two degenerate molecular orbitals, leaving a charged ionic species with a single unpaired electron and a net negative charge of −1. Both dioxygen and the superoxide anion are free radicals that exhibit paramagnetism. Superoxide was historically also known as "hyperoxide". Salts Superoxide forms salts with alkali metals and alkaline earth metals. The salts caesium superoxide (), rubidium superoxide (), potassium superoxide (), and sodium superoxide () are prepared by the reaction of with the respective ...

The O2 (Dublin)
The 3Arena (originally The O2) is an indoor amphitheatre located at North Wall Quay in the Dublin Docklands in Dublin, Ireland. The venue opened as The O2 on 16 December 2008. It was built on the site of the former Point Theatre, a smaller music venue which operated from 1988 to 2007, retaining only some of the outer facade. The Point Theatre was branded as "The Point Depot", in recognition of its original role as a railway goods handling station. The venue was re-branded on 4 September 2014 due to the takeover of O2 Ireland by Three Ireland. The venue is owned by a Live Nation subsidiary, Apollo Leisure Group Ltd. The venue is among the top ten busiest music arenas by ticket sales in the world. Naming Following its closure in 2007, the site underwent major redevelopment and was renamed The O2 after the telecommunication brand, O2, similar to The O2 in London. In 2008, O2 paid €25 million for the naming rights for 10 years. Following the sale of mobile network oper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxide
An oxide () is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2– (molecular) ion. with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials considered pure elements often develop an oxide coating. For example, aluminium foil develops a thin skin of Al2O3 (called a passivation layer) that protects the foil from further corrosion.Greenwood, N. N.; & Earnshaw, A. (1997). Chemistry of the Elements (2nd Edn.), Oxford:Butterworth-Heinemann. . Stoichiometry (the measurable relationship between reactants and chemical equations of a equation or reaction) Oxides are extraordinarily diverse in terms of stoichiometries and in terms of the structures of each stoichiometry. Most elements form oxides of more than one stoichiometry. A well known example is carbon monoxide and carbon dioxide.Greenwood, N. N.; & Earnshaw, A. (1997). Chemist ...

O2 Centre
The O2 Centre is an indoor shopping and entertainment centre that is open for around 18 hours per day located on Finchley Road in North West London, near Hampstead. It is now owned by Landsec, previously X Leisure, and opened in 1998. Despite the same name and originally very similar logo, it is no relation to the O2 telecommunications brand, which was launched 4 years later. The name was chosen as reference to the spacious feel of the building, as O2 is the chemical formula for dioxygen. With anchor units of Sainsbury's on level 0, Virgin Active (previously Esporta) on Level 1 and VUE cinema on Level 2, the centre is a unique mix of retail, entertainment and leisure – reflected in the centre's 18 hour+ opening times. It also has two gyms and a large car park. History Development The opening of the centre in 1998 came after many years of the site remaining derelict. In the early 1990s the buildings along Finchley Road were demolished in preparation for the centre, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O2 (O-Town Album)
''O2'' is the second studio album by American boy band O-Town. It was released by J Records on November 11, 2002 in the United States. ''O2'' was O-Town's last album to feature Ashley Parker Angel as a member of the group. Background The lead single, " These Are the Days", only reached number 64 on the US ''Billboard'' Hot 100 and failed to match the success of "Liquid Dreams" or "All or Nothing". The second single, "I Showed Her", failed to chart anywhere. However, the album showed more creative input from the band, as they co-wrote six of the songs. Despite this, they soon disbanded the following year. Critical reception AllMusic editor found that "backed by buoyant beats and haunting melodies old, new, borrowed and blue, flavored with the usual lyrics of love and loss (many penned by members of the band), O-Town transcends the above pitfalls on an album that stands strong amidst the boy-band world." Commercial Performance ''O2'' debuted and peaked at number 28 on the US ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O-type Star
An O-type star is a hot, blue-white star of spectral type O in the Yerkes classification system employed by astronomers. They have temperatures in excess of 30,000 kelvin (K). Stars of this type have strong absorption lines of ionised helium, strong lines of other ionised elements, and hydrogen and neutral helium lines weaker than spectral type B. Stars of this type are very rare, but because they are very bright, they can be seen at great distances and four of the 90 brightest stars as seen from Earth are O type.Those four stars are Gamma Velorum, Alnitak (Zeta Orionis), Mintaka (Delta Orionis), and Zeta Puppis. Due to their high mass, O-type stars end their lives rather quickly in violent supernova explosions, resulting in black holes or neutron stars. Most of these stars are young massive main sequence, giant, or supergiant stars, but the central stars of planetary nebulae, old low-mass stars near the end of their lives, also usually have O spectra. O-type stars are typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
