Political Repression In The Soviet Union
Throughout the history of the Soviet Union, tens of millions of people suffered political repression, which was an instrument of the state since the October Revolution. It culminated during the Stalin era, then declined, but it continued to exist during the "Khrushchev Thaw", followed by increased persecution of Soviet dissidents during the Brezhnev era, and it did not cease to exist until late in Mikhail Gorbachev's rule when it was ended in keeping with his policies of glasnost and perestroika. Origins and early Soviet times Secret police had a long history in Tsarist Russia. Ivan the Terrible used the Oprichina, while more recently the Third Section and Okrhana existed. Early on, the Leninist view of the class conflict and the resulting notion of the dictatorship of the proletariat provided the theoretical basis of the repressions. Its legal basis was formalized into the Article 58 in the code of Russian SFSR and similar articles for other Soviet republics. At times, th ...

Rehabilitation (Soviet)
Rehabilitation (russian: реабилитация, transliterated in English as ''reabilitatsiya'' or academically rendered as ''reabilitacija'') was a term used in the context of the former Soviet Union and the post-Soviet states. Beginning after the death of Stalin in 1953, the government undertook the political and social restoration, or political rehabilitation, of persons who had been repressed and criminally prosecuted without due basis. It restored the person to the state of acquittal. In many cases, rehabilitation was posthumous, as thousands of victims had been executed or died in labor camps. The government also rehabilitated several minority populations which it had relocated under Stalin, and allowed them to return to their former territories and in some cases restored their autonomy in those regions. Post-Stalinism epoch The government started mass amnesty of the victims of Soviet repressions after the death of Joseph Stalin. In 1953, this did not entail any form ...

Trotskyist
Trotskyism is the political ideology and branch of Marxism developed by Ukrainian-Russian revolutionary Leon Trotsky and some other members of the Left Opposition and Fourth International. Trotsky self-identified as an orthodox Marxist, a revolutionary Marxist, and Bolshevik–Leninist, a follower of Marx, Engels, and 3L: Vladimir Lenin, Karl Liebknecht, and Rosa Luxemburg. He supported founding a vanguard party of the proletariat, proletarian internationalism, and a dictatorship of the proletariat (as opposed to the " dictatorship of the bourgeoisie", which Marxists argue defines capitalism) based on working-class self-emancipation and mass democracy. Trotskyists are critical of Stalinism as they oppose Joseph Stalin's theory of socialism in one country in favour of Trotsky's theory of permanent revolution. Trotskyists criticize the bureaucracy and anti-democratic current developed in the Soviet Union under Stalin. Vladimir Lenin and Trotsky, despite their ideological disp ...

Abrasive
An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives. Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. This gives rise to a large variation in the physical and chemical composition of abrasives as well as the shape of the abrasive. Some common uses for abrasives include grinding, polishing, buffing, honing, cutting, drilling, sharpening, lapping, and sanding (see abrasive machining). (For simplicity, "mineral" in this article will be used loosely to refer to both minerals and mineral-like substances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrode
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery. The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity. Anode and cathode in electrochemical cells Electrodes are an essential part of any battery. The first electrochemical battery made was devised by Alessandro Volta and was aptly named the Voltaic cell. This battery consisted of a stack of copper and zinc electrodes separated by brine-soaked paper disks. Due to fluctuation in the voltage provided by the voltaic cell it wasn't very practical. The first practical battery was invented in 1839 and named the Daniell cell after John Frederic Daniell. Still making use of the zinc–copper electrode combination. Since then many more batteries have be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrochrome
Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight. Ferrochrome is produced by electric arc carbothermic reduction of chromite. Most of the global output is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources. Increasing amounts are coming from Russia and China. Production of steel, especially that of stainless steel with chromium content of 10 to 20%, is the largest consumer and the main application of ferrochrome. Usage Over 80% of the world's ferrochrome is utilised in the production of stainless steel. In 2006, 28,000,000 tons of stainless steel were produced. Stainless steel depends on chromium for its appearance and resistance to corrosion. Average chrome content in stainless steel is approx. 18%. It is also used to add chromium to carbon steel. FeCr from South Africa, known as "charge chrome" and produced from a Cr containing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
