Soledar Salt Mine
The Soledar Salt Mines (also called Artemsil Salt Mines after the State Enterprise Association Artemsil that operates the mines) are located in the city/suburb of Soledar in the Bakhmut municipality in Donetsk Oblast, Ukraine. The scale of the mines is vast, with of tunnels at a depth of , and many of the chambers are in height. The largest resembles a hangar of about length and width and height, and has accommodated soccer matches and the inflation of a hot air balloon. The temperature underground is constant at 14–15 °C, with 14.93 PSI air pressure and 60% humidity regardless of the time of the year, giving rise to claims of healing properties for lung conditions. Many of the chambers are exquisitely decorated with carvings in the salt rock. There are accommodation areas and even a church. A particle physics detector, the , is located in the mine. History The mining of salt started in the town of Soledar in the 19th century. Russian invasion of Ukraine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at , but only 8 g of water per cubic metre of air at . Three primary measurements of humidity are widely employed: absolute, relative, and specific. Ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Mines In Ukraine
Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater. The open ocean has about of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food, including otherwise unpalatable food. Salting, brining, and pickling are also ancient and important methods of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, Greeks, Romans, Byzantin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historical Regions In Ukraine
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Wieliczka Salt Mine
The Wieliczka Salt Mine ( pl, Kopalnia soli Wieliczka) is a salt mine in the town of Wieliczka, near Kraków in southern Poland. From Neolithic times, sodium chloride (table salt) was produced there from the upwelling brine. The Wieliczka salt mine, excavated from the 13th century, produced table salt continuously until 2007, as one of the world's oldest operating salt mines. Throughout its history, the royal salt mine was operated by the ''Żupy Krakowskie'' (Kraków Salt Mines) company."Wieliczka – The Salt of the Earth" at the WieliczkaSaltMine.net. . Ancient ...

Battle Of Soledar
The Battle of Soledar was a series of military engagements in and around the urban-type settlement of Soledar during the battle of Donbas in the 2022 Russian invasion of Ukraine. Russian forces began an offensive on 3 August 2022, shelling Soledar, Bakhmut, and surrounding villages to the south and east. Repeated local Russian assaults on or near Soledar continued into October, with many repelled by the Ukrainian army. By late December, much of the fighting in the region centered around Bakhmut, with Soledar seen as a satellite stronghold protecting the city's northeastern flank and supply lines. Much of the town had been reduced to ruins. Russian attacks to the town resumed in January 2023, and on 16 January Russian forces captured the last part of its industrial zone and secured control of the town. Over a week later, on 25 January, Ukraine confirmed their forces retreated from Soledar. Background During the eastern Ukraine campaign in the 2022 Russian invasion of Ukraine, R ...

Air Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The Standard atmosphere (unit), standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 Bar (unit), millibars, 760millimetre of mercury, mm Hg, 29.9212inch of mercury, inchesHg, or 14.696pounds per square inch, psi.International Civil Aviation Organization. ''Manual of the International Standard Atmosphere, ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the fluid pressure, hydrostatic pressure caused by the weight of Earth's atmosphere, air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
