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 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.

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), botani ...

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 ...

Estonia
Estonia, formally the Republic of Estonia, is a country by the Baltic Sea in Northern Europe. It is bordered to the north by the Gulf of Finland across from Finland, to the west by the sea across from Sweden, to the south by Latvia, and to the east by Lake Peipus and Russia. The territory of Estonia consists of the mainland, the larger islands of Saaremaa and Hiiumaa, and over 2,200 other islands and islets on the eastern coast of the Baltic Sea, covering a total area of . The capital city Tallinn and Tartu are the two largest urban areas of the country. The Estonian language is the autochthonous and the official language of Estonia; it is the first language of the majority of its population, as well as the world's second most spoken Finnic language. The land of what is now modern Estonia has been inhabited by '' Homo sapiens'' since at least 9,000 BC. The medieval indigenous population of Estonia was one of the last " pagan" civilisations in Europe to adopt Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ida-Virumaa Lipp
Ida-Viru County ( et, Ida-Viru maakond or ''Ida-Virumaa'') is one of 15 counties of Estonia. It is the most north-eastern 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%). History During the latter part of the peri ...

Gulf Of Finland
The Gulf of Finland ( fi, Suomenlahti; et, Soome laht; rus, Фи́нский зали́в, r=Finskiy zaliv, p=ˈfʲinskʲɪj zɐˈlʲif; sv, Finska viken) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in 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 of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. Proposals for a tunnel through the gulf have been made. Geography The gulf has an area of . The length (from the Hanko Peninsula to Saint Petersburg) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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.

The formal Western-oriented teaching that he received there set him apart from composers of the contemporary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...
