Copșa Mică Works
The Copșa Mică works were two factories in the Transylvanian town of Copșa Mică, Sibiu County, Romania. Sometra, established in 1939, produced non-ferrous metals, particularly zinc and lead, through smelting; production has been suspended since 2009. Carbosin, dating to 1935, specialized in carbon black, and shut down in 1993. The two were the town's principal employers, but combined, they made it among the most polluted places in Eastern Europe. Soot from Carbosin encased Copșa Mică in a black covering, while metals from Sometra suffused the air, water and soil, leading to serious health effects on surrounding residents, vegetation and wildlife. The factories Sometra Sometra was founded as a private firm in 1939 for the purpose of zinc smelting. Initially, it had three distillation furnaces, with five more added in 1948, the year it was nationalized by the new communist regime. Its initial capacity was 3000 tons of zinc per year, expanded to 4000 tons in 1946. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Czechoslovak Army
The Czechoslovak Army (Czech and Slovak: Československá armáda) was the name of the armed forces of Czechoslovakia. It was established in 1918 following Czechoslovakia's declaration of independence from Austria-Hungary. History In the first months of the World War I, the response of the Czech soldiers and civilians to the war and mobilisation efforts were highly enthusiastic, however it turned into apathy later. Although modeled after Austro-Hungarian Army patterns, the army of the newly established state also incorporated former members of the Czechoslovak Legion fighting alongside the Entente during World War I. Czechoslovak Army took part in the brief Polish-Czechoslovak War in which Czechoslovakia annexed the Zaolzie region from Poland. In the interbellum the force was fairly modern by contemporary standards, with the core of the force formed by LT vz. 38 and LT vz. 35 tanks, as well as an extensive system of border fortifications. Mobilised during the Munich Confe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Czechoslovak Republic
The First Czechoslovak Republic ( cs, První československá republika, sk, Prvá česko-slovenská republika), often colloquially referred to as the First Republic ( cs, První republika, Slovak: ''Prvá republika''), was the first Czechoslovak state that existed from 1918 to 1938, a union of ethnic Czechs and Slovaks. The country was commonly called Czechoslovakia (Czech and sk, Československo), a compound of ''Czech'' and ''Slovak''; which gradually became the most widely used name for its successor states. It was composed of former territories of Austria-Hungary, inheriting different systems of administration from the formerly Austrian ( Bohemia, Moravia, a small part of Silesia) and Hungarian territories (mostly Upper Hungary and Carpathian Ruthenia). After 1933, Czechoslovakia remained the only ''de facto'' functioning democracy in Central Europe, organized as a parliamentary republic. Under pressure from its Sudeten German minority, supported by neighbouring Nazi G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. It has also been detected on other plane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2007–2012 Global Financial Crisis
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arabs developed the digit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc Concentrate
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the ...

Romanian Revolution Of 1989
The Romanian Revolution ( ro, Revoluția Română), also known as the Christmas Revolution ( ro, Revoluția de Crăciun), was a period of violent civil unrest in Romania during December 1989 as a part of the Revolutions of 1989 that occurred in several countries around the world. The Romanian Revolution started in the city of Timișoara and soon spread throughout the country, ultimately culminating in the drumhead trial and execution of longtime Romanian Communist Party (PCR) General Secretary Nicolae Ceaușescu and his wife Elena, and the end of 42 years of Communist rule in Romania. It was also the last removal of a Marxist–Leninist government in a Warsaw Pact country during the events of 1989, and the only one that violently overthrew a country's leadership and executed its leader; according to estimates, over one thousand people died and thousands more were injured. Following World War II, Romania was placed under the Soviet sphere of influence in 1947 with Communist rul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stibnite
Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb2 S3. This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is derived from the Greek στίβι ''stibi'' through the Latin ''stibium'' as the former name for the mineral and the element antimony. Structure Stibnite has a structure similar to that of arsenic trisulfide, As2S3. The Sb(III) centers, which are pyramidal and three-coordinate, are linked via bent two-coordinate sulfide ions. However, some studies suggest that the actual coordination polyhedra of antimony are SbS7, with (3+4) coordination at the M1 site and (5+2) at the M2 site. Some of the secondary bonds impart cohesion and are connected with packing. Stibnite is grey when fresh, but can turn superficially black due to oxidation in air. Properties The melting point of Sb2S3 is . The band gap is 1.88 eV at room temperature and it is a photoco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
