Regional Center For Nuclear Studies
The Regional Center for Nuclear Studies in Kinshasa, Democratic Republic of the Congo, (CREN-K, french: Centre Régional d'Études Nucléaires de Kinshasa), prior to 1970 known as the Trico Center (french: Centre Trico), houses the TRICO I and TRICO II nuclear research reactors. TRICO I was the first nuclear reactor on the African continent. History In 1956, prior to the independence of the Democratic Republic of the Congo from Belgium, Luc Gillon, rector of Lovanium University launched the idea of establishing a research reactor at the university. In 1958, the government of Belgian Congo, with the approval of the Belgian minister of Congo and Ruanda-Urundi bought a TRIGA MARK I reactor from General Atomics. The Trico Center was constructed to house the reactor on land belonging to the science and medical faculties of the Lovanium University (later University of Kinshasa). It became operational in May 1959 and was incorporated into the studies of Congolese and other African student ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinshasa
Kinshasa (; ; ln, Kinsásá), formerly Léopoldville ( nl, Leopoldstad), is the capital and largest city of the Democratic Republic of the Congo. Once a site of fishing and trading villages situated along the Congo River, Kinshasa is now one of the world's fastest growing megacities. The city of Kinshasa is also one of the DRC's 26 provinces. Because the administrative boundaries of the city-province cover a vast area, over 90 percent of the city-province's land is rural in nature, and the urban area occupies a small but expanding section on the western side. Kinshasa is Africa's third-largest metropolitan area after Cairo and Lagos. It is also the world's largest nominally Francophone urban area, with French being the language of government, education, media, public services and high-end commerce in the city, while Lingala is used as a ''lingua franca'' in the street. Kinshasa hosted the 14th Francophonie Summit in October 2012. Residents of Kinshasa are known as ''Kinoi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCK•CEN
SCK CEN (the Belgian Nuclear Research Centre), until 2020 shortened as SCK•CEN, is the Belgian nuclear research centre located in Mol, Belgium, more specifically near the township of Donk. SCK CEN is a global leader in the field of nuclear research, services, and education. History SCK CEN was founded in 1952 and originally named Studiecentrum voor de Toepassingen van de Kernenergie (Research Centre for the Applications of Nuclear Energy), abbreviated to STK. Land was bought in the municipality of Mol, and over the next years many technical, administrative, medical, and residential buildings were constructed on the site. From 1956 to 1964 four nuclear research reactors became operational: the BR 1, BR 2, BR 3, the first pressurized water reactor in Europe, and VENUS. In 1963 SCK CEN already employed 1600 people, a number that would remain about the same over the next decades. In 1970 SCK CEN widened its field of activities outside the nuclear sector, but the emphasis remai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highly Enriched Uranium
Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 (238U with 99.2739–99.2752% natural abundance), uranium-235 (235U, 0.7198–0.7202%), and uranium-234 (234U, 0.0050–0.0059%). 235U is the only nuclide existing in nature (in any appreciable amount) that is fissile with thermal neutrons. Enriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons. The International Atomic Energy Agency attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb nuclear weapons proliferation. There are about 2,000 tonnes of highly enriched uranium in the world, produced mostly for nuclear power, nuclear weapons, naval propulsion, and smaller quantities for research reactors. ...

Characterization
Characterization or characterisation is the representation of persons (or other beings or creatures) in narrative and dramatic works. The term character development is sometimes used as a synonym. This representation may include direct methods like the attribution of qualities in description or commentary, and indirect (or "dramatic") methods inviting readers to infer qualities from characters' actions, dialogue, or appearance. Such a personage is called a character. Character is a literary element. History The term ''characterization'' was introduced in the 19th century.Harrison (1998, pp. 51-2) Aristotle promoted the primacy of plot over characters, that is, a plot-driven narrative, arguing in his ''Poetics'' that tragedy "is a representation, not of men, but of action and life." This view was reversed in the 19th century, when the primacy of the character, that is, a character-driven narrative, was affirmed first with the realist novel, and increasingly later with the inf ...

Medical Isotopes
A medical isotope is an isotope used in medicine. The first uses of isotopes in medicine were in radiopharmaceuticals, and this is still the most common use. However more recently, separated stable isotopes have also come into use. Examples of non-radioactive medical isotopes are: * Deuterium in deuterated drugs * Carbon-13 used in liver function and metabolic tests Radioactive isotopes used Radioactive isotopes are used in medicine for both treatment and diagnostic scans. The most common isotope used in diagnostic scans is Tc-99m (Technetium-99m), being used in approximately 85% of all nuclear medicine diagnostic scans worldwide. It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems. Another well-known radioactive isotope used in medicine is I-131 Iodine-131 (131I, I-131) is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California, Berkeley.

TRIGA
TRIGA (Training, Research, Isotopes, General Atomics) is a class of nuclear research reactor designed and manufactured by General Atomics. The design team for TRIGA, which included Edward Teller, was led by the physicist Freeman Dyson. Design TRIGA is a swimming pool reactor that can be installed without a containment building, and is designed for research and testing use by scientific institutions and universities for purposes such as undergraduate and graduate education, private commercial research, non-destructive testing and isotope production. The TRIGA reactor uses uranium zirconium hydride (UZrH) fuel, which has a large, prompt negative fuel temperature coefficient of reactivity, meaning that as the temperature of the core increases, the reactivity rapidly decreases. Because of this unique feature, it has been safely pulsed at a power of up to 22,000 megawatts. The hydrogen in the fuel is bound in the uranium zirconium hydride crystal structure with a vibrational energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Commissioner General
A commissioner (commonly abbreviated as Comm'r) is, in principle, a member of a commission or an individual who has been given a commission (official charge or authority to do something). In practice, the title of commissioner has evolved to include a variety of senior officials, often sitting on a specific commission. In particular, the commissioner frequently refers to senior police or government officials. A high commissioner is equivalent to an ambassador, originally between the United Kingdom and the Dominions and now between all Commonwealth states, whether Commonwealth realms, republics or countries having a monarch other than that of the realms. The title is sometimes given to senior officials in the private sector; for instance, many North American sports leagues. There is some confusion between commissioners and commissaries because other European languages use the same word for both. Therefore titles such as ''commissaire'' in French, ''Kommissar'' in German and ''com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Articles Of Association
In corporate governance, a company's articles of association (AoA, called articles of incorporation in some jurisdictions) is a document which, along with the memorandum of association (in cases where it exists) form the company's constitution, and defines the responsibilities of the directors, the kind of business to be undertaken, and the means by which the shareholders exert control over the board of directors. Articles of association are very critical documents to corporate operations, as they may regulate both internal and external affairs. Articles of incorporation, also referred to as the certificate of incorporation or the corporate charter, is a document or charter that establishes the existence of a corporation in the United States and Canada. They generally are filed with the Secretary of State in the U.S. State where the company is incorporated, or other company registrar. An equivalent term for limited liability companies (LLCs) in the United States is articles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobutu
Mobutu Sese Seko Kuku Ngbendu Wa Za Banga (; born Joseph-Désiré Mobutu; 14 October 1930 – 7 September 1997) was a Congolese politician and military officer who was the president of Zaire from 1965 to 1997 (known as the Democratic Republic of the Congo from 1965 to 1971). He also served as Chairman of the Organisation of African Unity from 1967 to 1968. During the Congo Crisis, Mobutu, serving as Chief of Staff of the Army and supported by Belgium and the United States, deposed the democratically elected government of left-wing nationalist Patrice Lumumba in 1960. Mobutu installed a government that arranged for Lumumba's execution in 1961, and continued to lead the country's armed forces until he took power directly in a second coup in 1965. To consolidate his power, he established the Popular Movement of the Revolution as the sole legal political party in 1967, changed the Congo's name to ''Zaire'' in 1971, and his own name to Mobutu Sese Seko in 1972. Mobutu claimed that h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
