The first results of the atmomagnetic control of environment. Case study from Kyiv(O. Menshov)
The greatest part of humanity today lives in cities and the urbanization trend in modern society will occur over the next decades. The working capacity of the population is largely determined by environmental conditions within the cities. The available ways of air pollution control are laborious and costly. Magnetic investigation of environmental pollution is the opportunity to intensify these control activities. Magnetic studies include the investigations of various objects that are able to accumulate dust particles dangerous to human health. The particles are transferred into air with magnetic minerals containing chemical compounds and elements. The selection of dust particles as an indicator of air pollution was conducted in our investigation. The initial results of magnetic susceptibility investigation for samples selected from flat surfaces using the original traps in different districts of Kyiv and its environs are demonstrated. Sampling points are differentiated by geographical orientation, technogenic load, height above Earth’s surface.
Keywords: atmosphere, pollution, magnetism.
Climate of the Earth is gettting warm becouse the Sun’s system is evolving (V.F. Blinov)
It is considered a heating of Earth’s climate from non-traditional point of view on the developmеnт of celestial bodies that accumulate mass, absorbing the ether’s matter from cosmic space. Astream of this matter toward the centre of bodies is not other than the kinetic energy of gravitational field that is transformed in interior of bodies into the mass of rest. Accumulation of mass and energy bring to the heating of planets and to the increasing of luminosity of Sun and stars.Mentioned phenomena increase of temperatures of the planetary atmospheres, including atmosphere of the Earth. Thus. the heating of Earth’s climate isnatural course of things, this process is not depend on Eath’s civilization.
