Kyiv Oblast
Kyiv Oblast ( uk, Ки́ївська о́бласть, translit=Kyïvska oblast), also called Kyivshchyna ( uk, Ки́ївщина), is an oblast (province) in central and northern Ukraine. It surrounds, but does not include, the city of Kyiv, which is a self-governing city with special status. The administrative center of the oblast is in Kyiv city, the capital of Ukraine, despite the city not being part of the oblast. The Kyiv metropolitan area extends out from Kyiv city into parts of the oblast, which is significantly dependent on the urban economy and transportation of Kyiv. The population of Kyiv Oblast is . Its largest city is Bila Tserkva, with a population over 200,000. The Chernobyl Exclusion Zone is in the northern part of Kyiv Oblast. It is administered separately from the oblast and public access is prohibited.

Sergej Vsekhsvyatskij
Sergius is a male given name of Ancient Roman origin after the name of the Latin ''gens'' Sergia or Sergii of regal and republican ages. It is a common Christian name, in honor of Saint Sergius, or in Russia, of Saint Sergius of Radonezh, and has been the name of four popes. It has given rise to numerous variants, present today mainly in the Romance (Serge, Sergio, Sergi) and Slavic languages (Serhii, Sergey, Serguei). It is not common in English, although the Anglo-French name Sergeant is possibly related to it. Etymology The name originates from the Roman ''nomen'' (patrician family name) ''Sergius'', after the name of the Roman ''gens'' of Latin origins Sergia or Sergii from Alba Longa, Old Latium, counted by Theodor Mommsen as one of the oldest Roman families, one of the original 100 ''gentes originarie''. It has been speculated to derive from a more ancient Etruscan name but the etymology of the nomen Sergius is problematic. Chase hesitantly suggests a connection with t ...

Ionosphere
The ionosphere () is the ionized part of the upper atmosphere of Earth, from about to above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on Earth. History of discovery As early as 1839, the German mathematician and physicist Carl Friedrich Gauss postulated that an electrically conducting region of the atmosphere could account for observed variations of Earth's magnetic field. Sixty years later, Guglielmo Marconi received the first trans-Atlantic radio signal on December 12, 1901, in St. John's, Newfoundland (now in Canada) using a kite-supported antenna for reception. The transmitting station in Poldhu, Cornwall, used a spark-gap transmitter to produce a signal with a freq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Currents
A telluric current (from Latin ''tellūs'', "earth"), or Earth current, This has a detailed history of observations as understood at the time. is an electric current which moves underground or through the sea. Telluric currents result from both natural causes and human activity, and the discrete currents interact in a complex pattern. The currents are extremely low frequency and travel over large areas at or near the surface of the Earth. Description Telluric currents are phenomena observed in the Earth's crust and mantle. In September 1862, an experiment to specifically address Earth currents was carried out in the Munich Alps (Lamont, 1862). Including minor processes, there are at least 32 different mechanisms which cause telluric currents. The strongest are primarily geomagnetically induced currents, which are induced by changes in the outer part of the Earth's magnetic field, which are usually caused by interactions between the solar wind and the magnetosphere or solar radiat ...

Aurora
An aurora (plural: auroras or aurorae), also commonly known as the polar lights, is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky. Auroras are the result of disturbances in the magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imp ...

Tiksi Bay
Tiksi Bay (russian: Бухта Тикси, ''Bukhta Tiksi'') is a bay of the Laptev Sea that cuts into the northern part of the Sakha Republic, Russia. History This bay was first surveyed by Russian Arctic explorer Dmitry Laptev in 1739. It was then called "Gorely Bay". The name "Tiksi Bay" was adopted in 1878. There is a cross at Tiksi Bay marking the place of death of U. S. whaling captain Thomas Long.Soviet Life, Issues 7-12 Geography The bay is up to 21 km long, 17 km wideGoogleEarth and has a depth of 2 to 11 metres.
