Informations

Bangui (French pronunciation: ​[bɑ̃ɡi]) (or Bangî in Sango, formerly written Bangi in English) is the capital and largest city of the Central African Republic. As of 2012 it had an estimated population of 734,350. It was recognized as a French outpost in 1889 and named after its location on the northern bank of the Ubangi River (French: Oubangui); the Ubangi itself was appointed from the Bobangi word for the"rapids" situated beside the settlement, which marked the end of navigable water north from Brazzaville. The majority of the population of the Central African Republic lives in the western parts of the country, in Bangui and the surrounding region. The city creates an autonomous commune (commune autonome) of the Central African Republic that's surrounded by the Ombella-M'Poko prefecture. Having an area of 67 square kilometres (26 sq mi), the commune is the smallest high-level administrative division in the nation, but the highest in terms of population.



The city consists of eight urban districts (arrondissements), 16 groups (groupements) and 205 neighbourhoods (quartiers). As the capital of the Central African Republic, Bangui acts as an administrative, trade, and industrial centre. It is served with the Bangui M'Poko International Airport. The National Assembly, government buildings, banks, foreign enterprises and embassies, hospitals, hotels, main markets and the Ngaragba Central Prison are located here. Bangui manufactures textiles, food products, beer, shoes and soap. Its Notre-Dame Cathedral is the seat of the Roman Catholic Archdiocese of Bangui. The city is also home to the University of Bangui, inaugurated in 1970. Bangui has been the scene of intense rebel activity and destruction during decades of political upheaval, including the recent rebellion. As a result of political unrest, the city was named in 1996 as one of the most dangerous on earth.

Informations

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was later thought to be due to the known metal bismuth. Miners had long used the name kobold ore (German for goblin ore) for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the kobold. Today, some cobalt is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). The element is, however, more usually produced as a by-product of copper and nickel mining.



The copper belt in the Democratic Republic of the Congo (DRC) and Zambia yields most of the global cobalt production. World production in 2016 was 116,000 metric tons (114,000 long tons; 128,000 short tons) (according to Natural Resources Canada), and the DRC alone accounted for more than 50%.Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys. The compounds cobalt silicate and cobalt(II) aluminate (CoAl2O4, cobalt blue) give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. Cobalt occurs naturally as only one stable isotope, cobalt-59. Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high-energy gamma rays. Cobalt is the active center of a group of coenzymes called cobalamins. Vitamin B12, the best-known example of the type, is an essential vitamin for all animals. Cobalt in inorganic form is also a micronutrient for bacteria, algae, and fungi.
