Smolensk Cathedral
Smolensk is a city and the administrative center of Smolensk Oblast, Russia, located on the Dnieper River, west-southwest of Moscow. First mentioned in 863, it is one of the oldest cities in Russia. It has been a regional capital for most of the past millennium, beginning as the capital of an eponymous principality in the 11th-15th centuries, then the Smolensk Voivodeship of Lithuania and Poland, and Smolensk Governorate and Oblast within Russia. It was the main stronghold of the Smolensk Gate, a geostrategically significant pass between the Daugava and Dnieper rivers, and as such was an important point of contention in the struggle for dominance in Eastern Europe, passing at various times between Lithuania, Poland and Russia. In more recent history, it was captured by Napoleon's Franco–Polish forces and Hitler's Germany during their marches towards Moscow, and was the place of the Smolensk air disaster of 2010.

Smolensk Kremlin
The Smolensk Kremlin () is a fortified complex (kremlin (fortification), kremlin) enclosing the center of the city of Smolensk in western Russia. The partially preserved fortress wall was built between 1595 and 1602, during the reigns of the tsars Feodor I of Russia, Feodor I and Boris Godunov. The length of the walls is about , of which less than the half was preserved. The fortifications were built under the supervision of the architect Fyodor Kon. The Smolensk Kremlin is classified as an architectural monument protected at the federal level, and also has a great historical significance, in particular, as the fortress protecting the Russian state from the west over centuries. History Smolensk historically had a great significance for the defence of Russia, and this is why Russian rulers paid considerable attention to its fortifications. In the spring of 1554, Tsar Ivan the Terrible ordered to build a new tall wooden fortress. After the development of artillery, it became clear ...

Daugava
The Daugava ( ), also known as the Western Dvina or the Väina River, is a large river rising in the Valdai Hills of Russia that flows through Belarus and Latvia into the Gulf of Riga of the Baltic Sea. The Daugava rises close to the source of the Volga. It is in length, of which are in Latvia and in Russia. It is a westward-flowing river, tracing out a great south-bending curve as it passes through northern Belarus. The city of Ķekava is located 6 miles south of the west bank of the river. Latvia's capital, Riga, bridges the river's estuary four times. Built on both riverbanks, the city centre is from the river's mouth and is a significant port. Etymology According to Max Vasmer's ''Etymological Dictionary'', the toponym Dvina cannot stem from a Uralic language; instead, it possibly comes from an Indo-European word which used to mean 'river' or 'stream'. The name ''Dvina'' strongly resembles '' Danuvius'' which is itself derived from the Proto-Indo-European ''*dānu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Byzantine Empire
The Byzantine Empire, also known as the Eastern Roman Empire, was the continuation of the Roman Empire centred on Constantinople during late antiquity and the Middle Ages. Having survived History of the Roman Empire, the events that caused the fall of the Western Roman Empire in the 5th centuryAD, it endured until the fall of Constantinople to the Ottoman Empire in 1453. The term 'Byzantine Empire' was coined only after its demise; its citizens used the term 'Roman Empire' and called themselves 'Romans'. During the early centuries of the Roman Empire, the western provinces were Romanization (cultural), Latinised, but the eastern parts kept their Hellenistic culture.

Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. ''World Flora Online'' accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, and ''Plants of the World Online'' 126 species-rank taxa (113 species and 13 nothospecies), making it the largest genus among the conifers. The highest species diversity of pines is found in Mexico. Pines are widely species distribution, distributed in the Northern Hemisphere; they occupy large areas of boreal forest, but are found in many habitats, including the Mediterranean Basin, and dry tropical forests in southeast Asia and Central America. Wood from pine trees is one of the most extensively used types of timber, and some pines are widely used as Christmas trees.

Pitch (resin)
Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, or plants. Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid form. Tar is sometimes used interchangeably with pitch, but generally refers to a more liquid substance derived from coal production, including coal tar, or from plants, as in pine tar. Uses Pitch, a traditional naval store, was traditionally used to help caulk the seams of wooden sailing vessels (see shipbuilding). Other important historic uses included coating earthenware vessels for the preservation of wine, waterproofing wooden containers, and making torches. It was also used to make patent fuel from coal slack around the turn of the 19th century. Petroleum-derived pitch is black in colour, hence the adjectival phrase "pitch-black". The viscoelastic properties of pitch make it well suited for the polishing of high-quali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resin
A resin is a solid or highly viscous liquid that can be converted into a polymer. Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds, predominantly terpenes. Common resins include amber, hashish, frankincense, myrrh and the animal-derived resin, shellac. Resins are used in varnishes, adhesives, food additives, incenses and perfumes. Resins protect plants from insects and pathogens, and are secreted in response to injury. Resins repel herbivores, insects, and pathogens, while the volatile natural phenol, phenolic compounds may attract benefactors such as predators of insects that attack the plant. Composition Most plant resins are composed of terpenes. Specific components are alpha-Pinene, alpha-pinene, pinene, beta-pinene, carene, delta-3 carene, and sabinene, the monocyclic terpenes limonene and terpinolene, and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene, and cad ...

Chernozem
Chernozem ( ),; also called black soil, regur soil or black cotton soil, is a black-colored soil containing a high percentage of humus (4% to 16%) and high percentages of phosphorus and ammonia compounds. Chernozem is very fertile soil and can produce high agricultural yields with its high moisture-storage capacity. Chernozems are a Reference Soil Group of the World Reference Base for Soil Resources (WRB). Distribution The name comes from the Russian terms for black (чёрный ''čjornyj'') and soil, earth or land (земля ''zemlja''). Studies of the steppe soils of the Poltava region in the Russian Empire in 1883, conducted by geologist Vasily Dokuchaev, showed that the peasants called all soils by color, so the scientist began to use such names. Chernozem was black in color due to the large amount of organic matter. Dokuchaev was the first to describe the chernozem of the European part of the Russian Empire, and discovered its fertility. It is distinct from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slavic Languages
The Slavic languages, also known as the Slavonic languages, are Indo-European languages spoken primarily by the Slavs, Slavic peoples and their descendants. They are thought to descend from a proto-language called Proto-Slavic language, Proto-Slavic, spoken during the Early Middle Ages, which in turn is thought to have descended from the earlier Proto-Balto-Slavic language, linking the Slavic languages to the Baltic languages in a Balto-Slavic languages, Balto-Slavic group within the Indo-European family. The current geographical distribution of natively spoken Slavic languages includes the Balkans, Central and Eastern Europe, and all the way from Western Siberia to the Russian Far East. Furthermore, the diasporas of many Slavic peoples have established isolated minorities of speakers of their languages all over the world. The number of speakers of all Slavic languages together was estimated to be 315 million at the turn of the twenty-first century. It is the largest and most d ...
