Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Geophysical Year
The International Geophysical Year (IGY; french: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted. Sixty-seven countries participated in IGY projects, although one notable exception was the mainland People's Republic of China, which was protesting against the participation of the Republic of China (Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization. The IGY encompassed eleven Earth sciences: aurora and airglow, cosmic rays, geomagnetism, gravity, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, seismology, and solar activity. The timing of the IGY was particularly suited for studying some of these phenomena, since it covered th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kwame Nkrumah University Of Science And Technology
Kwame Nkrumah University of Science and Technology (KNUST) is a public University of Ghana that focuses on science and technology. The Kwame Nkrumah University of Science and Technology is the public university established in the country, as well as the largest university in the Kumasi, Kumasi Metropolis and in the Ashanti Region of Ghana. KNUST has its roots in the plans of Prempeh I, Agyeman Prempeh I, a ruler of the Ashanti Kingdom, to establish a university in Kumasi as part of his drive towards modernization of his Ashanti Kingdom, Ashanti kingdom. This plan never came to fruition due to the clash between British Empire, British empire expansion and the desire for King Prempeh I to preserve his Ashanti kingdom's independence. However, his younger brother and successor, Osei Tutu Agyeman Prempeh II, King Asantehene Agyeman Prempeh II, upon ascending to the Golden Stool in 1935, continued with this vision. Events in the Gold Coast (region), Gold Coast in the 1940s played into his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gerboise Bleue (nuclear Test)
''Gerboise Bleue'' (; ) was the codename of the first French nuclear test. It was conducted by the Nuclear Experiments Operational Group (GOEN), a unit of the Joint Special Weapons Command on 13 February 1960, at the Saharan Military Experiments Centre near Reggane, French Algeria in the Sahara desert region of Tanezrouft, during the Algerian War. General Pierre Marie Gallois was instrumental in the endeavour, and earned the nickname of ''père de la bombe A'' ("father of the A-bomb"). Name ''Gerboise'' is the French word for jerboa, a desert rodent found in the Sahara. The color blue (''Bleue'') adjuncted is said to come from the first colour of the French Flag. Test Explosion On April 11, 1958, French Prime Minister Félix Gaillard ordered a nuclear test in the first quarter of 1960. President Charles de Gaulle reaffirmed the decision after the French Fourth Republic collapsed in the May 1958 crisis. On 13 February 1960 at 7:04:00 UTC, the plutonium filled bomb was de ...

Theobroma Cacao
''Theobroma cacao'', also called the cacao tree and the cocoa tree, is a small ( tall) evergreen tree in the family Malvaceae. Its seeds, cocoa beans, are used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. The largest producer of cocoa beans in 2018 was Ivory Coast, 2.2 million tons. Description Its leaves are alternate, entire, unlobed, long and broad. Flowers The flowers are produced in clusters directly on the trunk and older branches; this is known as cauliflory. The flowers are small, diameter, with pink calyx. The floral formula, used to represent the structure of a flower using numbers, is ✶ K5 C5 A(5°+52) (5). While many of the world's flowers are pollinated by bees ( Hymenoptera) or butterflies/moths ( Lepidoptera), cacao flowers are pollinated by tiny flies, ''Forcipomyia'' midges in the subfamily Forcipomyiinae. Using the natural pollinator ''Forcipomyia'' midges for ''Theobroma cacao'' was shown to have more fruit production th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dimethoate
Dimethoate is a widely used organophosphate insecticide and acaricide. It was patented and introduced in the 1950s by American Cyanamid. Like other organophosphates, dimethoate is an acetylcholinesterase inhibitor which disables cholinesterase, an enzyme essential for central nervous system function. It acts both by contact and through ingestion. It is readily absorbed and distributed throughout plant tissues, and is degraded relatively rapidly. Fruit Fly Control Efforts The Queensland fruit fly, or ''Bactrocera tryoni'', is a tephritid fly species that has caused more than $28.5 million a year in damage to Australian fruit crops. In order to combat infestation, farmers treated crops with dimethoate and fenthion Fenthion is an organothiophosphate insecticide, avicide, and acaricide. Like most other organophosphates, its mode of action is via cholinesterase inhibition. Due to its relatively low toxicity towards humans and mammals, fenthion is listed as .... However, the us ...

Strontium-90
Strontium-90 () is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years. It undergoes β− decay into yttrium-90, with a decay energy of 0.546 MeV. Strontium-90 has applications in medicine and industry and is an isotope of concern in fallout from nuclear weapons, nuclear weapons testing, and nuclear accidents. Radioactivity Naturally occurring strontium is nonradioactive and nontoxic at levels normally found in the environment, but 90Sr is a radiation hazard. 90Sr undergoes β− decay with a half-life of 28.79 years and a decay energy of 0.546 MeV distributed to an electron, an antineutrino, and the yttrium isotope 90Y, which in turn undergoes β− decay with a half-life of 64 hours and a decay energy of 2.28 MeV distributed to an electron, an antineutrino, and 90Zr (zirconium), which is stable. Note that 90Sr/Y is almost a pure beta particle source; the gamma photon emission from the decay of 90Y is so infrequent that it ...
