Sillamäe Kalev
Sillamäe (Estonian for 'Bridge Hill'; also known by the Germanised names of ''Sillamäggi'' or ''Sillamägi'') is a town in Ida-Viru County in the northern part of Estonia, on the southern coast of the Gulf of Finland. It has a population of 13,666 (as of 1 January 2017) and covers an area of 10.54 km2. Sillamäe is located at the mouth of Sõtke River. History The locality of Sillamäggi was first mentioned in 1502 when the area was under the control of the Livonian Order. The bridge across Sõtke and a mill in Sillamäggi were documented in 1700. In the 1800s, Sillamäggi developed into a resort village offering a more tranquil experience than the nearby resort town of Hungerburg. Russian physiologist Ivan Pavlov owned a dacha in Sillamäggi and vacationed there during summer breaks in 1891–1917. Among other famous vacationers of Sillamäggi were poet Konstantin Balmont (1905), painter Albert Benois (1898 and 1899), physicist Paul Ehrenfest (1908–1912), botanist ...

List Of Cities And Towns In Estonia
The following is a list of the 47 cities and towns in Estonia. Before the Republic of Estonia became an in independent nation in 1918, many of these locations were known in the rest of the world by their German language names which were occasionally quite different from the ones used in the Estonian language. During the 1944–1991 Soviet occupation of Estonia, placenames were transliterated into Russian (Cyrillic alphabet) in the Soviet central government's documents, which in turn lead to the use of several incorrect back-transliterations from Russian (Cyrillic) alphabet into English (and other Latin alphabets) in some English-language maps and texts during the second half of the 20th century (for example, incorrect ''Pyarnu'', ''Vilyandi'', ''Pylva'', instead of the correct Pärnu, Viljandi, Põlva). Tallinn is the capital and the most populous city of Estonia. There are 46 other ''linn'', i.e. cities and towns in Estonia (as of 2022). The Estonian word ''linn'' means both "a ...

Konstantin Balmont
Konstantin Dmitriyevich Balmont ( rus, Константи́н Дми́триевич Бальмо́нт, p=kənstɐnʲˈtʲin ˈdmʲitrʲɪjɪvʲɪdʑ bɐlʲˈmont, a=Konstantin Dmitriyevich Bal'mont.ru.vorb.oga; – 23 December 1942) was a Russian symbolist poet and translator who became one of the major figures of the Silver Age of Russian Poetry. Balmont's early education came from his mother, who knew several foreign languages, was enthusiastic about literature and theater, and exerted a strong influence on her son. He then attended two gymnasiums, was expelled from the first for political activities, and graduated from the second. He started studying law at the Imperial Moscow University in 1886, but was quickly expelled (1887) for taking part in student unrest. He tried again at the Demidov Law College from 1889, but dropped out in 1890.

Basidiolichen
Basidiolichens are lichenized members of the Basidiomycota, a much smaller group of lichens than the far more common ascolichens in the Ascomycota. In arctic, alpine, and temperate forests, the most common basidiolichens are in the agaric genus ''Lichenomphalia'' (including former members of ''Omphalina'' or '' Gerronema'') and the clavarioid genus ''Multiclavula''. Several lichenized genera occur in tropical regions, the most common being the foliose ''Dictyonema''. Previously basidiolichens had been classified in their own subclass, Basidiolichenes.

Uranium Oxide
Uranium oxide is an oxide of the element uranium. The metal uranium forms several oxides: * Uranium dioxide or uranium(IV) oxide (UO2, the mineral uraninite or pitchblende) * Diuranium pentoxide or uranium(V) oxide (U2O5) * Uranium trioxide or uranium(VI) oxide (UO3) * Triuranium octoxide (U3O8), the most stable uranium oxide; yellowcake typically contains 70 to 90 percent triuranium octoxide) * Uranyl peroxide (UO2O2 or UO4) * Amorphous uranium(VI) oxide (''Am''-U2O7) Uranium dioxide is oxidized in contact with oxygen Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as wel ... to form triuranium octoxide. :3 UO2 + O2 → U3O8; at 700 °C (970 K) Preparation 38 During World War II, "Preparation 38" was the codename for uranium oxide used by German scientists.

Battle Of Narva (1944)
The Battle of Narva was a World War II military campaign, lasting from 2 February to 10 August 1944, in which the German Army Detachment "Narwa" and the Soviet Leningrad Front fought for possession of the strategically important Narva Isthmus. The battle took place in the northern section of the Eastern Front and consisted of two major phases: the Battle for Narva Bridgehead (February to July 1944), and the Battle of Tannenberg Line (July–August 1944). The Soviet Kingisepp–Gdov Offensive and Narva Offensives ( 15–28 February, 1–4 March and 18–24 March) were part of the Red Army Winter Spring Campaign of 1944. Following Joseph Stalin's "broad front" strategy, these battles coincided with the Dnieper–Carpathian Offensive (December 1943 – April 1944) and the Lvov–Sandomierz Offensive (July–August 1944). A number of foreign volunteers and local Estonian conscripts participated in the battle as part of the German forces with Army Group North. By giving ...

Battle Of Tannenberg Line
The Battle of Tannenberg Line (german: Die Schlacht um die Tannenbergstellung; russian: Битва за линию «Танненберг») or the Battle of the Blue Hills ( et, Sinimägede lahing) was a military engagement between the German Army Detachment Narwa and the Soviet Leningrad Front. They fought for the strategically important Narva Isthmus from 25 July–10 August 1944. The battle was fought on the Eastern Front during World War II.

Shale Oil Extraction
Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities. Shale oil extraction is usually performed above ground (''ex situ'' processing) by mining the oil shale and then treating it in processing facilities. Other modern technologies perform the processing underground (on-site or ''in situ'' processing) by applying heat and extracting the oil via oil wells. The earliest description of the process dates to the 10th century. In 1684, Great Britain granted the first formal extraction process patent. Extraction industries and innovations became widespread during the 19th century. The industry shrank in the mid-20th century following the discovery of large reserves of conventional oil, ...

Oil Shale In Estonia
There are two kinds of oil shale in Estonia, both of which are sedimentary rocks laid down during the Ordovician geologic period. Graptolitic argillite is the larger oil shale resource, but, because its organic matter content is relatively low, it is not used industrially. The other is kukersite, which has been mined for more than a hundred years. Kukersite deposits in Estonia account for 1% of global oil shale deposits. Oil shale ( et, põlevkivi; literally: burning rock) has been defined as a strategic energy resource in Estonia and the oil shale industry in Estonia is one of the most developed in the world. IEA (2013), p. 20 Historically, most of mined oil shale was used for electricity generation. Of all the oil shale fired power stations in the world, the two largest are in Estonia. Although its share decreased in the decade to 2022, direct and indirect use of oil shale still generates about half of Estonia's electricity. About half of mined oil shale is used to ...

Pyotr Ilyich Tchaikovsky
Pyotr Ilyich Tchaikovsky , group=n ( ; 7 May 1840 – 6 November 1893) was a Russian composer of the Romantic period. He was the first Russian composer whose music would make a lasting impression internationally. He wrote some of the most popular concert and theatrical music in the current classical repertoire, including the ballets '' Swan Lake'' and ''The Nutcracker'', the ''1812 Overture'', his First Piano Concerto, Violin Concerto, the ''Romeo and Juliet'' Overture-Fantasy, several symphonies, and the opera ''Eugene Onegin''. Although musically precocious, Tchaikovsky was educated for a career as a civil servant as there was little opportunity for a musical career in Russia at the time and no system of public music education. When an opportunity for such an education arose, he entered the nascent Saint Petersburg Conservatory, from which he graduated in 1865. The formal Western-oriented teaching that he received there set him apart from composers of the contemporary nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
