Energy objects, installations of high and ultra-high voltage, are considered man-made, dangerous objects in terms of the intensity of the electric and magnetic field distribution, which create ion shells in high-altitude zones and spread a certain radius on the territory of a residential area. In this regard, during the construction and commissioning of low-frequency power facilities, it is necessary to conduct a specific environmental analysis on the selected territory. One of the main sanitary and epidemiological requirements for the construction and commissioning of high – voltage power lines is to take into account changes in the daily and seasonal distribution of electrical loads along high-voltage power lines, which have a continuous dynamic characteristic that increases the level of electric and magnetic field strength. In turn, the development of information support for environmental problems of the territory based on GIS technologies makes it possible to record information about the ecological state of the territory at a specific time and present this state with a set of thematic environmental maps of various territorial or district entities. It should be noted that the above characteristics increase the advantage of geoinformation technologies as an information platform of the database, which will make it possible to obtain data for processing operational analyses and conclusions about the state of the environment around high-voltage power lines.

We have previously reported the isolation of carbohydrates, alcohols, and acids from E. lamprocarpa Benth. [1].In this paper we give the results of a study of the triterpene compounds from E. jaxartica I)rokh.The eomminuted raw material was extracted with chloroform. The chloroform was distilled off and the residue was dissolved in acetone. The aeetone-spluble fraction was treated with petroleum ether and chromatographed on alumina. Elution was then carried out successively with petroleum ether, benzene, acetone, and methanol. A mixture with an authentic sample of euphol gave no depression of the melting point and their IR spectra were identical.The second ethereal eluate and the acetone eluate yielded crystals with the composition C~lH~zO , mp 126-127 ° C, [oz]~ ±0% The substance formed anO-acetyl derivative with mp 126 ° C. The properties of this substance were identical with those of euphorbol, also isolated from spurge [4]. A mixture of the substance that we had obtained with euphorbol gave no depression of the melting point, and their IR spectra were identical.

This paper presents a technology for applying copper and silver films to cotton fabrics by combining photochemical and chemical methods for the reduction of the compounds of these metals. The resulting metal-containing films have inherent electrical conductivity of metals. All the main processes described in the work were carried out by means of the compounds being sorbed by the surface of the fabric when they were wetted in appropriate solutions. The aim of the work was to study the application of electrically conductive composite copper films on cotton fabrics. The tasks to achieve this aim were to perform scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction analysis to confirm that as a result of the experiment, CuCl with a semiconductor ability was formed on the surface of the sample. The driving force behind the photochemical reduction of copper and silver halides on cotton surfaces is that, as a result of the photooxidation of cellulose molecules in the fabric, copper monochloride is first formed on the cotton surface. Subsequently, the process of obtaining silver particles based on semiconductor silver chloride obtained as a result of the transformation of copper monochloride was carried out. The physicochemical and photochemical processes leading to the formation of monovalent copper chloride, which provides sufficient adhesion to the substrate, are considered. It is shown that in this case, the oxidation of monovalent copper also occurs with the formation of soluble salts that are easily removed by washing. Since the proposed technology does not require special equipment, and the chemical reagents used are not scarce, it can be used to apply bactericidal silver films to various household items and medical applications in ordinary laundries or at home. This article examines an affordable and simple technology for producing metal films on a cotton surface due to the presence of disadvantages (time duration, high temperature, scarce reagents, special installations, etc.) of a number of well-known methods in the production of chemical coatings.
