.ac.uk
.uk is the Internet country code top-level domain (ccTLD) for the United Kingdom. It was first registered in July 1985, seven months after the original generic top-level domains such as .com and the first country code after .us. , it is the fifth most popular top-level domain worldwide (after .com, .cn, .de and .net), with over 10 million registrations. .uk has used OpenDNSSEC since March 2010. History In October 1984, RFC 920 set out the creation of ccTLDs using country codes derived from the corresponding two-letter code in the ISO 3166-1 list. "GB" is the UK's ISO 3166 country code. However, the UK academic network Name Registration Scheme, JANET NRS, had defined "UK" as the top-level domain a few months before the compilation of the ISO-derived list. Consequently, .uk was chosen and registered on 24 July 1985. .gb was reserved but never widely used and it is no longer possible to register domains under that ccTLD. As with other ccTLDs in the early days it w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joint European Torus
The Joint European Torus, or JET, is an operational magnetically confined plasma physics experiment, located at Culham Centre for Fusion Energy in Oxfordshire, UK. Based on a tokamak design, the fusion research facility is a joint European project with a main purpose of opening the way to future nuclear fusion grid energy. At the time of its design JET was larger than any comparable machine. JET was built with the hope of reaching ''scientific breakeven'' where the fusion energy gain factor ''Q'' =1.0. It began operation in 1983 and spent most of the next decade increasing its performance in a lengthy series of experiments and upgrades. In 1991 the first experiments including tritium were made, making JET the first reactor in the world to run on the production fuel of a 50–50 mix of tritium and deuterium. It was also decided to add a divertor design to JET, which occurred between 1991 and 1993. Performance was significantly improved, and in 1997 JET set the record for t ...

Parliament Of The United Kingdom
The Parliament of the United Kingdom is the Parliamentary sovereignty in the United Kingdom, supreme Legislature, legislative body of the United Kingdom, the Crown Dependencies and the British Overseas Territories. It meets at the Palace of Westminster, London. It alone possesses Parliamentary sovereignty, legislative supremacy and thereby ultimate power over all other political bodies in the UK and the overseas territories. Parliament is Bicameralism, bicameral but has three parts, consisting of the Monarchy of the United Kingdom, sovereign (King-in-Parliament), the House of Lords, and the House of Commons of the United Kingdom, House of Commons (the Parliament Acts 1911 and 1949, primary chamber). In theory, power is officially vested in the Queen-in-Parliament, King-in-Parliament. However, the Crown normally acts on the Advice (constitutional), advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation; thus power is ''de facto ...

JANET NRS
The JANET NRS (''Name Registration Scheme'') was a pseudo-hierarchical naming scheme used on British academic and research networks in the 1980s. It used a reverse domain name notation. History It was proposed in 1983 and used until the superficially similar Internet Domain Name System was fully adopted. Structure The NRS " second-level domains" consisted of (JANET academic and scientific sites), (commercial) and (Ministry of Defence). Any organisations not falling into these categories were given their own "second-level" name, e.g. (British Library) or ( National Engineering Laboratory). All NRS names had both a ''standard'' (long) and ''abbreviated'' (up to 18 characters) form. For example, was the less widely used standard equivalent of the abbreviated name . For email, interoperability between the " Grey Book" email addressing style of and ARPA and USENET addresses of the style was achieved by way of mail gateway at University College London.

Second-level Domains
In the Domain Name System (DNS) hierarchy, a second-level domain (SLD or 2LD) is a domain that is directly below a top-level domain (TLD). For example, in , is the second-level domain of the TLD. Second-level domains commonly refer to the organization that registered the domain name with a domain name registrar. Some domain name registries introduce a second-level hierarchy to a TLD that indicates the type of entity intended to register an SLD under it. For example, in the .uk namespace a college or other academic institution would register under the ccSLD, while companies would register under . Strictly speaking, domains like .ac.uk and .co.uk are second level domain themselves, since they are right below a TLD. A list of the official TLDs can be found at icann.org and iana.org. An ordinal-free term to denote domains under which people can register their own domain name is public suffix domain (PSD). Country-code second-level domains Algeria Australia Austria In A ...

Tokamak
A tokamak (; russian: токамáк; otk, 𐱃𐰸𐰢𐰴, Toḳamaḳ) is a device which uses a powerful magnetic field to confine plasma in the shape of a torus. The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power. , it was the leading candidate for a practical fusion reactor. Tokamaks were initially conceptualized in the 1950s by Soviet physicists Igor Tamm and Andrei Sakharov, inspired by a letter by Oleg Lavrentiev. The first working tokamak was attributed to the work of Natan Yavlinsky on the T-1 in 1958. It had been demonstrated that a stable plasma equilibrium requires magnetic field lines that wind around the torus in a helix. Devices like the z-pinch and stellarator had attempted this, but demonstrated serious instabilities. It was the development of the concept now known as the safety factor (labelled ''q'' in mathematical notation) that guided tokamak development; by arra ...

National Health Service
The National Health Service (NHS) is the umbrella term for the publicly funded healthcare systems of the United Kingdom (UK). Since 1948, they have been funded out of general taxation. There are three systems which are referred to using the "NHS" name (NHS England, NHS Scotland and NHS Wales). Health and Social Care in Northern Ireland was created separately and is often locally referred to as "the NHS". The four systems were established in 1948 as part of major social reforms following the Second World War. The founding principles were that services should be comprehensive, universal and free at the point of delivery—a health service based on clinical need, not ability to pay. Each service provides a comprehensive range of health services, free at the point of use for people ordinarily resident in the United Kingdom apart from dental treatment and optical care. In England, NHS patients have to pay prescription charges; some, such as those aged over 60 and certain state ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
