Por-Bazhyn Reconstruction 2008 R
Por-Bazhyn (Por-Bajin, Por-Bazhyng, russian: Пор-Бажын, Tuvan: Пор-Бажың) is a ruined structure on a lake island high in the mountains of southern Tuva (Russian Federation). The name derives . Excavations suggest that it was built as a Uyghur palace in the 8th century AD, converted into a Manichaean monastery soon after, abandoned after a short occupation, and finally destroyed by an earthquake and subsequent fire. Its construction methods show that Por-Bazhyn was built within the Tang Chinese architectural tradition. Location and description Por-Bazhyn occupies a small island in Lake Tere-Khol, about above sea level in the Sengelen mountains of southern Siberia. The location is west of the village of Kungurtuk in the southeast of the Republic of Tuva (Russian Federation), close to the Russian border with Mongolia. The walls of the site enclose a rectangular area of , oriented east–west and covering almost the entire island. The interior is taken up by two ...

Tuva
Tuva (; russian: Тува́) or Tyva ( tyv, Тыва), officially the Republic of Tuva (russian: Респу́блика Тыва́, r=Respublika Tyva, p=rʲɪˈspublʲɪkə tɨˈva; tyv, Тыва Республика, translit=Tyva Respublika ), is a federal subject of Russia (a republic, also defined in the Constitution of the Russian Federation as a state). The Tuvan Republic lies at the geographical center of Asia, in southern Siberia. The republic borders the Altai Republic, the Republic of Khakassia, Krasnoyarsk Krai, Irkutsk Oblast, and the Republic of Buryatia in Russia and Mongolia to the south. Tuva has a population of 307,930 ( 2010 census). Its capital is the city of Kyzyl. From 1921 to 1944, Tuva constituted a sovereign, independent, but partially recognized nation, acknowledged only by its neighbors the Soviet Union and Mongolia. It was known officially as Tannu Tuva until 1926 and thereafter as the Tuvan People's Republic. A majority of the population are ethni ...

Permafrost
Permafrost is ground that continuously remains below 0 °C (32 °F) for two or more years, located on land or under the ocean. Most common in the Northern Hemisphere, around 15% of the Northern Hemisphere or 11% of the global surface is underlain by permafrost, with the total area of around 18 million km2. This includes substantial areas of Alaska, Greenland, Canada and Siberia. It can also be located on mountaintops in the Southern Hemisphere and beneath ice-free areas in the Antarctic. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface. It frequently occurs in ground ice, but it can also be present in non-porous bedrock. Permafrost is formed from ice holding various types of soil, sand, and rock in combination. Permafrost contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide, making tundra soil a carbon sink. As global war ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Dendrochronology
Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology derives from Ancient Greek (), meaning "tree", (), meaning "time", and (), "the study of". Dendrochronology is useful for determining the precise age of samples, especially those that are too recent for radiocarbon dating, which always produces a range rather than an exact date. However, for a precise date of the death of the tree a full sample to the edge is needed, which most trimmed timber will not provide. It also gives data on the timing of events and rates of change in the environment (most prominently climate) and also in wood found in archaeology or works of art and architecture, such as old panel paintings. It is also used as a check in radiocar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dougong
''Dougong'' () is a structural element of interlocking wooden brackets, one of the most important in traditional Chinese architecture. The use of dougong first appeared in buildings of the late centuries BC and evolved into a structural network that joined pillars and columns to the frame of the roof. ''Dougong'' was widely used by the ancient Chinese during the Spring and Autumn period (770–476 BC) and developed into a complex set of interlocking parts by its peak in the Tang and Song periods. The pieces are fitted together by joinery alone without glue or fasteners, requiring precise carpentry. After the Song Dynasty, brackets and bracket sets used in palatial structures and important religious buildings became more ornamental than structural, no longer fitting the description of traditional ''dougong''. Function Dougong is part of the network of wooden supports essential to the timber frame structure of traditional Chinese building. Because the walls in these st ...

Dragon Tile From Por-Bazhyn
A dragon is a reptilian legendary creature that appears in the folklore of many cultures worldwide. Beliefs about dragons vary considerably through regions, but dragons in western cultures since the High Middle Ages have often been depicted as winged, horned, and capable of breathing fire. Dragons in eastern cultures are usually depicted as wingless, four-legged, serpentine creatures with above-average intelligence. Commonalities between dragons' traits are often a hybridization of feline, reptilian and avian features. Scholars believe huge extinct or migrating crocodiles bear the closest resemblance, especially when encountered in forested or swampy areas, and are most likely the template of modern Oriental dragon imagery. Etymology The word ''dragon'' entered the English language in the early 13th century from Old French ''dragon'', which in turn comes from la, draconem (nominative ) meaning "huge serpent, dragon", from Ancient Greek , (genitive , ) "serpent, gi ...
