FRACTOGRAPHY OF OPERATION FAILURE OF THE LITING GEAR OF BULLDOZER
DescriptionThe nature and causes of operational failure of the all-metal hydraulic cylinder rod of a bulldozer were studied. It is shown that the main mechanism of failure was evolving in time metal fatigue, initiated by defects of the heat treatment for chromizing

ACTIONS FOR PROTECTION OF THE ENVIROMENT IN THE DEVELOPMENT OF PRIDOROZHNOE MINEFIELD (PERM REGION)
04.00.00 Geological-mineralogical sciences
DescriptionIn this article we have analyzed the geological structure and hydrogeological conditions of the minefield; we have also shown the characteristic of land planned for recultivation. We have found that recultivation provides different directions

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

MODELS AND TABLES OF GROWTH OF ARTIFICIAL ORIGIN OAK FORESTS IN THE LOWER VOLGA REGION
DescriptionThe article discusses the function of growth for the simulation of forest indices of individual tree element of the forest. Algorithm calculate tables of growth based on materials by eye-measuring taxation on the basis of patterns of variability of the amount of Room space of sections of stands of oak is proposed. Tables of growth of stands of different density are developed

ANALYSIS OF SYNANTHROPIC FLORA OF RICE SYSTEMS OF THE KRASNODAR REGION
DescriptionThis article has given the analysis of systematic and ecological structures of synanthropic flora of rice sys-tems of the Krasnodar region. There was shown the relation of plants of aboriginal and adventive frac-tions of flora to different ecological factors. There were studied the timeness of different plant species to elements of the rice system and the degree dependence of their distribution on rice growing tech-nology

Description
This article discusses the use of nuclear magnetic resonance spectroscopy for the determination of biologically active substances-producing plants in the culture of in vitro and in situ. The same is said about the benefits of obtaining biologically active substances from plants in culture in vitro. Formulated a number of problems for theoretical study and experimental development basic principles on the use of nuclear magnetic resonance spectroscopy in pharmaceutical analysis for standardization and quality assessment of BAS
