Building materialBuilding material is material used for construction. Many naturally occurring substances, such as clay, rocks, sand, wood, and even twigs and leaves, have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic. The manufacturing of building materials is an established industry in many countries and the use of these materials is typically segmented into specific specialty trades, such as carpentry, insulation, plumbing, and roofing work.
South OssetiaSouth Ossetia (ɒˈsɛtiə , ɒˈsiːʃə ), officially the Republic of South Ossetia – the State of Alania, is a partially recognised landlocked state in the South Caucasus. It has an officially stated population of just over 56,500 people (2022), who live in an area of , with 33,000 living in the capital city, Tskhinvali. As of 2023, only Russia, Venezuela, Nicaragua, Nauru, and Syria recognise South Ossetia as a sovereign state. The Georgian government and nearly all United Nations member states consider South Ossetia a sovereign territory of Georgia occupied by Russia.
SheepSheep (: sheep) or domestic sheep (Ovis aries) are a domesticated, ruminant mammal typically kept as livestock. Although the term sheep can apply to other species in the genus Ovis, in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe (juː), an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb.
KazakhsThe Kazakhs (also spelled Qazaqs; Kazakh: қазақ, qazaq, qɑˈzɑq, қазақтар, qazaqtar, qɑzɑqˈtɑr) are a Turkic people native to Central Asia and Eastern Europe, mainly Kazakhstan, but also parts of northern Uzbekistan and the border regions of Russia, as well as northwestern China (specifically Ili Kazakh Autonomous Prefecture) and western Mongolia (Bayan-Ölgii Province).The Kazakhs arose from the merging of the medieval Turkic and Mongol tribes.
FeltFelt is a textile that is produced by matting, condensing, and pressing fibers together. Felt can be made of natural fibers such as wool or animal fur, or from synthetic fibers such as petroleum-based acrylic or acrylonitrile or wood pulp–based rayon. Blended fibers are also common. Natural fibre felt has special properties that allow it to be used for a wide variety of purposes. "It is fire-retardant and self-extinguishing; it dampens vibration and absorbs sound; and it can hold large amounts of fluid without feeling wet.
Green roofA green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier and drainage and irrigation systems. Container gardens on roofs, where plants are maintained in pots, are not generally considered to be true green roofs, although this is debated. Rooftop ponds are another form of green roofs which are used to treat greywater.
WoolWool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Wool is produced by follicles which are small cells located in the skin.
StoveA stove or range is a device that burns fuel or uses electricity to generate heat inside or on top of the apparatus, to be used for general warming or cooking. It has evolved highly over time, with cast-iron and induction versions being developed. Stoves can be powered with many fuels, such as electricity, gasoline, wood, and coal. Due to concerns about air pollution, efforts have been made to improve stove design. Pellet stoves are a type of clean-burning stove.
Cold waveA cold wave (known in some regions as a cold snap, cold spell or Arctic Snap) is a weather phenomenon that is distinguished by a cooling of the air. Specifically, as used by the U.S. National Weather Service, a cold wave is a rapid fall in temperature within a 24-hour period requiring substantially increased protection to agriculture, industry, commerce, and social activities. The precise criteria for a cold wave are the rate at which the temperature falls, and the minimum to which it falls.
Dukha peopleThe Dukha, Dukhans or Duhalar (Цаатан, Tsaatan) are a small Tuvan (Tozhu Tuvans) Turkic community of semi-nomadic reindeer herders living in Khövsgöl, the northernmost province of Mongolia. The name Tsaatan, which means ‘those who have reindeer’ in the Mongolian language, were originally Tuvinian reindeer herders.
