Sillamäe
Sillamäe (Estonian for 'Bridge Hill'; also known by the Germanised names of ''Sillamäggi'' or ''Sillamägi'') is a town in Ida-Viru County in the northeastern part of Estonia, on the southern coast of the Gulf of Finland. It has a population of 12,439 (as of 2021) and covers an area of 10.54 km2. Sillamäe is located at the mouth of the Sõtke River. Its population is predominantly Russian-speaking. History The locality of Sillamäggi was first mentioned in 1502 when the area was under the control of the Livonian Order. The bridge across the Sõtke River 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. The Russian physiologist Ivan Pavlov owned a dacha in Sillamäggi and vacationed there during summer breaks from 1891 to 1917. Among other famous vacationers of Sillamäggi were the poet Konstantin Balmont (1905), painter Albert Ben ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 mining, mined for more than a hundred years. Kukersite Deposit (geology), deposits in Estonia account for 1% of oil shale reserves, global oil shale deposits. Oil shale (; 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, 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 Electricity sector in Estonia, E ...

Ida-Virumaa Lipp
Ida-Viru County ( or ; ) is one of the 15 counties of Estonia. It is the most northeastern part of the country. The county contains large deposits of oil shale the main mineral mined in Estonia. Oil shale is used in the production of shale oil and in thermal power plants. The capital of the county is the town of Jõhvi which is administratively united with the Jõhvi Parish; nevertheless, Narva is the largest town in the county in terms of population and at the same time the third largest city in Estonia after Tallinn and Tartu. In January 2019 Ida-Viru County had a population of 136,240 – constituting 10.3% of the total population in Estonia. It borders Lääne-Viru County in the west, Jõgeva County in the southwest and Russia (Leningrad Oblast) in the east. It is the only county in Estonia where Russians constitute the majority of population (73.1% in 2010), the second highest being Harju (28%).

Estonia
Estonia, officially the Republic of Estonia, is a country in Northern Europe. It is bordered to the north by the Gulf of Finland across from Finland, to the west by the Baltic Sea across from Sweden, to the south by Latvia, and to the east by Russia. The territory of Estonia consists of the mainland, the larger islands of Saaremaa and Hiiumaa, and over 2,300 other islands and islets on the east coast of the Baltic Sea. Its capital Tallinn and Tartu are the two largest List of cities and towns in Estonia, urban areas. The Estonian language is the official language and the first language of the Estonians, majority of its population of nearly 1.4 million. Estonia is one of the least populous members of the European Union and NATO. Present-day Estonia has been inhabited since at least 9,000 BC.

Gulf Of Finland
The Gulf of Finland (; ; ; ) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg—the second largest city of Russia—to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the gulf belong to Russia, and some of Russia's most important oil harbors are located there, including Primorsk, Leningrad Oblast, Primorsk. As the seaway to Saint Petersburg, the gulf is of considerable strategic importance to Russia. Some of the Baltic Sea#Environmental status, environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. Proposals for an undersea tunnel, undersea Helsinki–Tallinn Tunnel through the gulf have been made. Geography The Gulf of Finland has an area of .

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 independent nation in 1918, many of these locations were known in the rest of the world by their German names, which were occasionally quite different from the ones used in the Estonian. 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 led 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 'city' and 'town'.

Oil Shale
Oil shale is an organic-rich Granularity, fine-grained sedimentary rock containing kerogen (a solid mixture of Organic compound, organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens. Based on their deposition environment, oil shales are classified as marine, lacustrine and terrestrial oil shales. Oil shales differ from oil-''bearing'' shales, shale deposits that contain petroleum (tight oil) that is sometimes produced from drilled wells. Examples of oil-''bearing'' shales are the Bakken Formation, Pierre Shale, Niobrara Formation, and Eagle Ford Group, Eagle Ford Formation. Accordingly, shale oil produced from oil shale should not be confused with tight oil, which is also frequently called shale oil. A 2016 estimate of global Deposition (geology), deposits set the total world resources of oil shale equivalent of of oil in place.#wec2016, WEC (2016), p. ...

Eastern European Summer Time
Eastern European Summer Time (EEST) is one of the names of the UTC+03:00 time zone, which is 3 hours ahead of Coordinated Universal Time. It is used as a summer daylight saving time in some European and Middle Eastern countries, which makes it the same as Arabia Standard Time, East Africa Time, and Moscow Time. During the winter periods, Eastern European Time ( UTC+02:00) is used. Since 1996, European Summer Time has been applied from the last Sunday in March to the last Sunday in October. Previously, the rules were not uniform across the European Union. Usage The following countries and territories use Eastern European Summer Time during the summer: * Belarus, Moscow Summer Time in years 1981–89, regular EEST from 1991-2011 * Bulgaria, regular EEST since 1979 * Cyprus, regular EEST since 1979 ( Northern Cyprus stopped using EEST in September 2016, but returned to EEST in March 2018) * Egypt, in the years 1988–2010, 2014–2015 and since 2023 (see also Egypt Sta ...

Andrei Famintsyn
Andrei Sergeyevich Famintsyn (; 29 June (Old Style, O.S. 17 June) 1835, Moscow – 8 December 1918, Petrograd) was a Russian Empire, Russian botanist, public figure, and academician of the Petersburg Academy of Sciences (1884). Career Famintsyn attended Saint Petersburg State University and studied under Russian fungal expert Lev Semionovich Tsenkovsky. In 1861, he continued his scientific career as a teacher at his alma mater and became a professor (1867-1889). In 1890, Famintsyn founded and headed the Laboratory of Plant Anatomy and Physiology of the Academy of Sciences (today's Timiryazev Institute of Plant Physiology of the Russian Academy of Sciences). Famintsyn is considered the founding father of the Petersburg School of plant physiologists (Ivan Borodin, Alexander Batalin, Dmitry Ivanovsky and others). In 1887, he authored the first Russian textbook on plant physiology. In 1906-1909, he was the president of the Free Economic Society. In 1915, Famintsyn was elected hono ...

Graptolitic Argillite
Graptolitic argillite (also known as dictyonema argillite, dictyonema oil shale, dictyonema shale, or Tremadocian black shale) is a marinite-type black shale of sapropelic origin. It is a blackish to greyish lithified claystone. The known occurrence of this rock is a graptolitic argillite of the Türisalu Formation in northern Estonia and northwest Russia. It is correlated with Swedish alum shale being its younger facial eastward continuation, and both being a part of the Baltoscandic Cambrian-Ordovician black shale, together with black shales in the Oslo region in Norway, Bornholm, Denmark, and Poland. Other known occurrences are in North America, Dover et al. (1980), p. 1 the Malay Peninsula, and New Zealand. Although the name dictyonema argillite is widely used instead of graptolitic argillite, this name is now considered a misnomer as the graptolite fossils in the rock, earlier considered dictyonemids, were reclassified during the 1980s as members of the genus '' ...

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 it ...
