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 da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joint European Torus
The Joint European Torus (JET) was a magnetically confined plasma physics experiment, located at Culham Centre for Fusion Energy in Oxfordshire, UK. Based on a tokamak design, the fusion research facility was a joint European project with the 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 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 mix of 50–50 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 the closest approach to scientific breakeven, reaching ''Q'' = 0.67 in 1997, producing 16 MW of fusion power while injecting 24&nbs ...

Parliament Of The United Kingdom
The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body of the United Kingdom, and may also legislate for the Crown Dependencies and the British Overseas Territories. It meets at the Palace of Westminster in London. Parliament possesses legislative supremacy and thereby holds ultimate power over all other political bodies in the United Kingdom and the Overseas Territories. While Parliament is bicameral, it has three parts: the sovereign, the House of Lords, and the House of Commons. The three parts acting together to legislate may be described as the King-in-Parliament. The Crown normally acts on the advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation. The House of Commons is the elected lower chamber of Parliament, with elections to 650 single-member constituencies held at least every five years under the first-past-the-post system.

UKAEA
The United Kingdom Atomic Energy Authority is a UK government research organisation responsible for the development of fusion energy. It is an executive non-departmental public body of the Department for Energy Security and Net Zero (DESNZ). The authority focuses on United Kingdom and European fusion energy research programmes at Culham in Oxfordshire, including the world's most powerful operating fusion device, the Joint European Torus (JET). The research aims to develop fusion power as a commercially viable, environmentally responsible energy source for the future. A record 59 megajoules of sustained fusion energy was demonstrated by scientists and engineers working on JET in December 2021. In JET's final deuterium-tritium experiments (DTE3), high fusion power was consistently produced for 5 seconds, resulting in a ground-breaking record of 69 megajoules using a mere 0.2 milligrams of fuel. JET has now ceased operating and decommissioning has commenced. United Kingdom Atomic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JANET NRS
The JANET NRS (''Name Registration Scheme'') was a pseudo-hierarchical naming scheme used on British academic and research networks in the 1980s. Its purpose was to organise and manage domain names within the JANET network, contributing to the establishment of computer networking familiarities at universities in the United Kingdom and other academic and research institutions. It used a reverse domain name notation. History It was proposed in 1983 and used until the superficially similar Internet Domain Name System (DNS) was fully adopted. Purpose and structure The JANET NRS was developed to allocate and maintain unique domain names for organisations connected to the JANET network. Its primary purpose was to ensure a standardised and organised approach to domain name registration, facilitating identification and differentiation of institutions and their computer resources on the network. NRS "second-level domains" consisted of (JANET academic and scientific sites), (commerci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 registry, 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 Aust ...

Tokamak
A tokamak (; ) is a device which uses a powerful magnetic field generated by external magnets to confine plasma (physics), plasma in the shape of an axially symmetrical torus. The tokamak is one of several types of magnetic confinement fusion, magnetic confinement devices being developed to produce controlled thermonuclear fusion power. The tokamak concept is currently one of the leading candidates for a practical fusion reactor for providing minimally polluting electrical power. The proposal to use controlled thermonuclear fusion for industrial purposes and a specific scheme using thermal insulation of high-temperature plasma by an electric field was first formulated by the Soviet physicist Oleg Lavrentiev in a mid-1950 paper. In 1951, Andrei Sakharov and Igor Tamm modified the scheme by proposing a theoretical basis for a thermonuclear reactor, where the plasma would have the shape of a torus and be held by a magnetic field. The first tokamak was built in the Soviet Union ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Health Service
The National Health Service (NHS) is the term for the publicly funded health care, publicly funded healthcare systems of the United Kingdom: the National Health Service (England), NHS Scotland, NHS Wales, and Health and Social Care (Northern Ireland) which was created separately and is often referred to locally as "the NHS". The original three systems were established in 1948 (NHS Wales/GIG Cymru was founded in 1969) 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. Each service provides a comprehensive range of health services, provided without charge for residents of 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, or those on certain state benefits, are exempt. Taken together, the four services in 2015–16 employed around 1.6 million people ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
