High Quality Content by WIKIPEDIA articles! A pyrotechnic fastener (also called an explosive bolt, or pyro, within context) is a fastener, usually a nut or bolt, that incorporates a pyrotechnic charge that can be initiated remotely. One or more explosive charges embedded within the bolt are typically activated by an electric current, and the charge breaks the bolt into two or more pieces. The bolt is typically scored around its circumference at the point(s) where the severance should occur. Such bolts are often used in space applications to ensure separation between rocket stages, because they are lighter and much more reliable than mechanical latches.

A p–n diode is a type of two-terminal semiconductor diode based upon the p–n junction that conducts current in only one direction, made by joining a p-type semiconducting layer to an n-type semiconducting layer. For a discussion of dopant impurities and the terminology p- and n-type. see Doping (semiconductor).

The Q Theatre, seating 490 in 25 rows with a central aisle, was opened in 1924 near Kew Bridge in west London by Jack and Beatie de Leon, and was one of a number of small, committed, independent theatre companies which included the Hampstead Everyman, the Arts Theatre Club and the Gate Theatre Studio. These theatres took risks by producing new and experimental plays which, although often at first thought to be commercially unviable on the West-End stage, later went on to transfer successfully.

It is the world`s third tallest residential tower after the 348 metre building The Marina Torch in Dubai won formal recognition as the tallest residential building in the world on 29 April 2011 by the Emporis Standards Committee and the Council on Tall Buildings and Urban Habitat. Q1 is the tallest building in Australia and the Southern Hemisphere when measured to the top of its spire (second tallest building behind Eureka Tower in Melbourne, when measured to roof and highest habitable floor) and the second-tallest free-standing structure in the Southern Hemisphere, behind Auckland`s...

The Qatar Bahrain Causeway (also referred to as the Qatar Bahrain Friendship Bridge) is an often announced, often delayed planned causeway between the two Arab states of Qatar and Bahrain. It was announced on the 13th of December 2008 that construction would start in early 2009, and would cost approximately US$2.3 billion to complete. As of November 2010, construction had not started, and the Qatar-Bahrain Causeway project was on hold, while the contracting consortium involved with the project was said to be demobilising, according to a source at the Qatar Bahrain Causeway Foundation (QBCF). On January 14, 2011, Bahrain`s Foreign Minister stated that the project should nevertheless be...

High Quality Content by WIKIPEDIA articles! Quantm is a software package that is used to optimise the routes of roads and railways. This was hitherto a tedious and laborious task as huge amounts of data are involved and the number of options is large as well. The Quantm software takes all the data and constraints and generates a prioritised list of good options that the user can choose between.
High Quality Content by WIKIPEDIA articles! In physics, a quantum phase transition (QPT) is a phase transition between different quantum phases (phases of matter at zero temperature). Contrary to classical phase transitions, quantum phase transitions can only be accessed by varying a physical parameter - such as magnetic field or pressure - at absolute zero temperature. The transition describes an abrupt change in the ground state of a many-body system due to its quantum fluctuations. Such quantum phase transitions can be second-order phase transition.

Quantum dot solar cells are an emerging field in solar cell research that uses quantum dots as the photovoltaic material, as opposed to better-known bulk materials such as silicon, copper indium gallium selenide (CIGS) or CdTe. Quantum dots have bandgaps that are tunable across a wide range of energy levels by changing the quantum dot size. This is in contrast to bulk materials, where the bandgap is fixed by the choice of material composition. This property makes quantum dots attractive for multi-junction solar cells, where a variety of different energy levels are used to extract more power from the solar spectrum.
High Quality Content by WIKIPEDIA articles! A quarry is a type of open-pit mine from which rock or minerals are extracted. Quarries are generally used for extracting building materials, such as dimension stone, construction aggregate, riprap, sand, and gravel. They are often collocated with concrete and asphalt plants due to the requirement for large amounts of aggregate in those materials. The word quarry can include underground quarrying for stone, such as Bath stone.
High Quality Content by WIKIPEDIA articles! A quasiperiodic crystal, or, in short, quasicrystal, is a structure that is ordered but not periodic. A quasicrystalline pattern can continuously fill all available space, but it lacks translational symmetry. While crystals, according to the classical crystallographic restriction theorem, can possess only two, three, four, and six-fold rotational symmetries, the Bragg diffraction pattern of quasicrystals shows sharp peaks with other symmetry orders, for instance five-fold.
