04.00.00 Geological-mineralogical sciences
04.00.00 Geological-mineralogical sciences
DescriptionHydrogeological conditions and problems of regional hydrogeological works of the territory of the Perm Ural and Priurals are characterized. Possibility of providing the population is shown by fresh underground waters. The methodology of mapping of the water-bearing zones on a complex of the methods including the lineament-geodynamic analysis with allocation of geodynamic active zones on the basis of remote researches and geoinformation technologies is considered

EFFECT OF RECREATIONAL LOAD ON SOIL RESERVE “UTRISH”
04.00.00 Geological-mineralogical sciences
DescriptionThe original soils were investigated at the Black Sea coast of Russia. Severe degradation of the soil in a Utrish nation reserve were identified as a result of high recreational pressure. Soils with high recreational load have low humus content (2-3 times) and a lower en-zymatic activity than the control of the soil. Biological parameters can be successfully used for environmental monitoring of soil of Utrish reserve, in contrast to the chemical and physic-chemical properties

CHANGE OF BIOLOGICAL ACTIVITY OF SOILS OF NORTH CAUCASUS IN RELATION TO CLIMATE
04.00.00 Geological-mineralogical sciences
DescriptionClimatic conditions have considerable impact on biological properties of soils of the South of Russia. From all studied indicators the most dependent on climate there was maintenance of a humus and activity of polyphenoloxidases and peroxidases. Values of the integrated indicator of a biological condition (IIBC) on a profile of soils decrease in process of increase in an amount of precipitation, decrease in temperature, and increase in height of the district in next order: meadow subalpine → brown forest → gray forest → black leached soil → black typical soil → black ordinary soi

EFFICIENCY OF USING OF THROTTLING ELEMENTS AT THE PUMP PLANTS
DescriptionIn the article, we have examined the operation modes of the pump units when their efficiency is regulated by the force of throttling. Formulas for optimal operation mode are derived and zones for efficient work of the electric pumps with different initial parameters of reg-ulations are defined

Description
In the article, we have given the recommendations for using of the theory developed by us for the synthesis of technical systems (TS) of the process of choice knowledge from the area of knowledge. The developed methodology for the research of the real system (RS) and the synthesis of TS can be used in the development of the scientific direction - the artificial intelligence (AI). Also, for the solution of problems where you want to automate the process of choosing the desired knowledge of specific area of knowledge. The developed theory for obtaining a binary tree of nodes of the system of questions and answers will help synthesize any TS where there is a choice of knowledge of a given area of knowledge. This theory will be developed further with the self-development of TS as part of the AI system

Description
In this article we have examined the following is-sues: structure flowcharts’ settlements and opera-tional peculiarities of converters and stabilizers of electrical parameters of wind power plants, solar power plants and mini-hydropower plants. All tech-nical decisions are covered by patents of the Russian Federation

Description
It is shown that the combination of the cold equal channel pressing with low-temperature annealing leads to the formation of a sub-microcrystalline ferritic matrix hardened with nanoscale particles of the carbide phase in steel 09G2S. Resulting structure leads to the achievement of the high-strength state, as well as a significant reduction of the wear intensity of the material
