Petukhovskoye (lake)
Petukhovskoye (russian: Петуховское), also known as Petukhovo, is an alkaline lake in Klyuchevsky District, Altai Krai, Russian Federation.Google Earth The lake is located at the western edge of the Krai, only east of the Russia-Kazakhstan border. The nearest inhabited place is Severka to the east of the eastern end. Klyuchi, the district capital, lies to the north. Geography Located in the Kulunda Plain, Petukhovskoye has an elongated shape, stretching roughly from northeast to southwest for approximately . The lake dries during summers of drought, becoming a salt pan. Salt was mined in the lake in the past. The indicator minerals in the sediments of the lake are pyrite, disordered Ca- smectites, and dolomite, the latter being markedly predominant, especially in the lower part of the sediment section. The water has a mineralization of and a pH of 9.8. Metagenomic analyses of lake samples collected in July 2016 indicate the presence of archaea belonging to ...

Sentinel-2
Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission is currently a constellation with two satellites, Sentinel-2A and Sentinel-2B; a third satellite, Sentinel-2C, is currently undergoing testing in preparation for launch in 2024. The mission supports a broad range of services and applications such as agricultural monitoring, emergencies management, land cover classification or water quality. Sentinel-2 has been developed and is being operated by the European Space Agency, and the satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen. Overview The Sentinel-2 mission has the following key characteristics: * Multi-spectral data with 13 bands in the visible, near infrared, and short wave infrared part of the spectrum * Systematic global coverage of land surfaces from 56° S to 84°&nb ...

Dolomite (mineral)
Dolomite () is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone. History As stated by Nicolas-Théodore de Saussure the mineral dolomite was probably first described by Carl Linnaeus in 1768. In 1791, it was described as a rock by the French naturalist and geologist Déodat Gratet de Dolomieu (1750–1801), first in buildings of the old city of Rome, and later as samples collected in the mountains now known as the Dolomite Alps of northern Italy. Nicolas-Théodore de Saussure first named the mineral (after Dolomieu) in March 1792. Properties The mineral dolomite crystallizes in the trigonal-rhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. Unless it ...

Lakes Of Altai Krai
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forest Steppe
A forest steppe is a temperate-climate ecotone and habitat type composed of grassland interspersed with areas of woodland or forest. Locations Forest steppe primarily occurs in a belt of forest steppes across northern Eurasia from the eastern lowlands of Europe to eastern Siberia in northeast Asia. It forms transition ecoregions between the temperate grasslands and temperate broadleaf and mixed forests biomes. Much of Russia belongs to the forest steppe zone, stretches from Central Russia, across Volga, Ural, Siberian and Far East Russia. In upper North America another example of the forest steppe ecotone is the aspen parkland, in the central Prairie Provinces, northeastern British Columbia, North Dakota, and Minnesota. It is the transition ecoregion from the Great Plains prairie and steppe temperate grasslands to the Taiga biome forests in the north. In central Asia the forest steppe ecotone is found in ecoregions in the mountains of the Iranian Plateau, in Iran, Afghanistan ...

PubMed is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintain the database as part of the Entrez system of information retrieval. From 1971 to 1997, online access to the MEDLINE database had been primarily through institutional facilities, such as university libraries. PubMed, first released in January 1996, ushered in the era of private, free, home- and office-based MEDLINE searching. The PubMed system was offered free to the public starting in June 1997. Content In addition to MEDLINE, PubMed provides access to: * older references from the print version of '' Index Medicus'', back to 1951 and earlier * references to some journals before they were indexed in Index Medicus and MEDLINE, for instance ''Science'', ''BMJ'', and '' Annals of Surgery'' * very recent entries to records for an article be ...

Microbes
A microorganism, or microbe,, ''mikros'', "small") and ''organism'' from the el, ὀργανισμός, ''organismós'', "organism"). It is usually written as a single word but is sometimes hyphenated (''micro-organism''), especially in older texts. The informal synonym ''microbe'' () comes from μικρός, mikrós, "small" and βίος, bíos, "life". is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax. Because micr ...
