Opera (web browser)

Opera is a web browser developed by Opera Software. The latest version is available for Microsoft Windows, OS X, and Linux operating systems, and uses the Blink layout engine. An earlier version using the Presto layout engine is still available, and additionally runs on FreeBSD systems.

Opera siblings – Opera Mobile, Opera Mini and Opera Coast – work on devices running Android, iOS, Windows Phone, Symbian, Maemo, Bada, BlackBerry and Windows Mobile operating systems, while Opera Mini runs on Java ME-capable devices.

According to Opera Software, the browser had more than 350 million users worldwide in the 4th quarter 2014. Total Opera mobile users reached 291 million in June 2015. Opera has been noted for originating many features later adopted by other web browsers. A prominent example is Speed Dial.

History

Opera began in 1994 as a research project at Telenor, the largest Norwegian telecommunications company. In 1995, it branched out into a separate company named Opera Software ASA. Opera was first released publicly with version 2.0 in 1996, which only ran on Microsoft Windows. In an attempt to capitalize on the emerging market for Internet-connected handheld devices, a project to port Opera to mobile device platforms was started in 1998. Opera 4.0, released in 2000, included a new cross-platform core that facilitated creation of editions of Opera for multiple operating systems and platforms.

Opera (magazine)

Opera is a monthly British magazine devoted to covering all things related to opera. It contains reviews and articles about current opera productions internationally, as well as articles on opera recordings, opera singers, opera companies, opera directors, and opera books. The magazine also contains major features and analysis on individual operas and people associated with opera.

The magazine employs a network of international correspondents around the world who write for the magazine. Contributors to the magazine, past and present, include William Ashbrook, Martin Bernheimer, Julian Budden, Rodolfo Celletti, Alan Blyth, Elizabeth Forbes, and J.B. Steane among many others.

Opera is printed in A5 size, with colour photos, and consists of around 130 pages. Page numbering is consecutive for a complete year (e.g. September 2009 goes from p1033-1168). All issues since August 2006 are available online to current subscribers (through Exact Editions).

Based in London, the magazine was founded in 1950 by George Lascelles, 7th Earl of Harewood. It was launched at the house of Richard Buckle, under the imprint 'Ballet Publications Ltd'.

Ópera (Madrid Metro)

Ópera is a station on Line 2, Line 5 and Ramal of the Madrid Metro. It is located in fare Zone A, in the Plaza de Isabel II, in the central district of Madrid. The station provides access to an area with tourist landmarks such as Teatro Real, Plaza de Oriente and the Royal Palace. Its name comes from nearby Madrid opera house, the Teatro Real.

History

The station was opened to the public in 1925 for lines 2 and Ramal later that year. Its original name was Isabel II, under the square in which it stood. The platforms of lines 2 and Ramal are located at the same level, the former is 60 m long and the latter being shorter in the beginning, but later it was extended in length to 60 m, too.

After the proclamation of the Second Republic on 14 April 1931, the new authorities approved by Decree of 20 April the removal of all the denominations that made references to the monarchy. Therefore, on 24 June Isabel II station was renamed Ópera. That same year, the square also changed his name to Fermín Galán, one of the leaders of the failed uprising in 1930 tried to overthrow King Alfonso XIII. On 5 June 1937 the station changed its name to coincide with the square. However, after the establishment of the dictatorship of Francisco Franco there was a further change in the names of city streets, stations, etc. Therefore, in 1939 the square was again renamed Isabel II, and the metro station recovered the name Ópera.

Stratigraphic unit

A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.

Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%".

Lithostratigraphic units

Sequences of sedimentary and volcanic rocks are subdivided on the basis of their lithology. Going from smaller to larger in scale, the main units recognised are Bed, Member, Formation, Group and Supergroup.

Bed

A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in the case of a marker horizon.

Member

A member is a named lithologically distinct part of a formation. Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation.

1994 Group

The 1994 Group was a coalition of smaller research-intensive universities in the United Kingdom, founded in 1994 to defend these universities' interests following the creation of the Russell Group by larger research-intensive universities earlier that year. The 1994 Group originally represented seventeen universities, rising to nineteen, and then dropping to eleven. The Group started to falter in 2012, when a number of high performing members left to join the Russell Group. The 1994 Group ultimately dissolved in November 2013.

Role

The group sought "to represent the views of its members on the current state and the future of higher education through discussions with the government, funding bodies, and other higher education interest groups" and "[made] its views known through its research publications and in the media".

University Alliance, million+, GuildHE and the Russell Group were its fellow university membership groups across the UK higher education sector.
