The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere.
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
Balloons cannot reach it because the air is too thin, but satellites cannot orbit there because the air is too thick. Hence, most experiments on the ionosphere give only small pieces of information. HAARP approaches the study of the ionosphere by following in the footsteps of an ionospheric heater called EISCAT near Tromsø, Norway. There ...
Aleksandr Georgievich Loran, also known as Aleksandr Lovan or Aleksandr Lavrentyev, Alexander Laurant (Russian: Александр Георгиевич Лоран; 1849 – c. 1911) was a teacher and inventor of fire fighting foam and foam extinguishers. He lived in the Russian Empire. A modern foam fire extinguisher.
International Reference Ionosphere (IRI) is a common permanent scientific project of the Committee on Space Research (COSPAR) and the International Union of Radio Science (URSI) started 1968/69. It is the international standard empirical model for the terrestrial ionosphere since 1999.
Ways to improve financial security in retirement. The need for more protection for IRA investors is a no-brainer. IRAs hold around $15.2 trillion in assets compared to approximately $8.9 trillion ...
The F-region is the highest region of the ionosphere. Consisting of the F1 and F2 layers, its distance above the Earth's surface is approximately 200–500 km. [7] The duration of these storms are around a day and reoccur every approximately 27.3 days. [6] Most ionospheric abnormalities occur in the F2 and E layers of the ionosphere.
Elon Musk said on Thursday his AI chatbot, and ChatGPT challenger, Grok 3, is in the final stages of development and will be released in about a week or two. "Grok 3 has very powerful reasoning ...
