THE TRANSGRESSION OF KAZAKHS OF BUKEY HORDE ON THE TERRITORY OF LOWER VOLGA FRONTIER
DescriptionThe article deals with the problem of transgression of Kazakhs of Bukey horde on the territory of Lower Volga frontier. Transgression of the frontier territory is a way to adapt to the new conditions of existence. The author pays attention to Bukey horde, where the new frontiry space is formed by the interaction of the various ethnic groups. Having come to the new land, and interacted with the Russian people and the Russian authorities, the Kazakhs turned out in the alien cultural landscape. Kazakhs` mentality is being changed against the background of the collapsing patriarchal way of life. Bukeyev inhabitants life was transformed by the alteration of social norms. The way of life of Bukey Horde was changed and they had to adapt to new realities. The author of the article gives examples of Kazakhs` transgression using archival date

THE DEVICE FOR STORING AGRICULTURAL MACHINERY IN PROTECTED FORM IN OUTDOOR AREAS
DescriptionThe carried out analysis studies the influence of various factors on the preservation of agricultural products and shows that it is largely determined by design features of machinery and technological methods of use. The efficiency of agricultural and mobile trailer machines has been forming by service and storage. Low quality of work associated with the storage of agricultural machines is conditioned by the fact that the lack of financial capacity of rural producers on acquisitions of modern equipment and materials for carrying out the preparation of for long storage, and also the construction of modern agricultural machinery storage sites. If a car can be fully or partially protected from the solar radiation, rain and snow, simply by removing it in the room, under a canopy or covered with a protective cover, by the formation of condensation on the surface of the machine units and parts these ways to protect do not work. Enhancing of preservation of agricultural machinery is possible when protecting the vehicles from atmospheric precipitation in the form of snow and rain, influence of solar radiation, and also due to the change heat exchange processes of the machine with the environment that prevents the formation of moisture condensate on its surface, ie. we have to create conditions when cooling rate at which the surface of the machine would be equal to or less the rate of cooling air. This is possible through the use of a special design, which would prevent the intense heat radiation of the machine into the environment, ie, would reflect heat rays using its surface and return them to its surface and thus fulfill the role of the heat shield

PHOTOVOLTAIC PLANTS: PROSPECTS, ADVANTAGES, DISADVANTAGES AND THEIR CHARACTERISTICS
DescriptionAnalysis of scientific literature has shown a promising direction in energy saving and in increasing of efficiency of power supplies remote from external networks in Russia is the application of solar photovoltaic power plants. The level of solar radiation on the territory of Russia varies widely from 810 kWh/m2 per year in remote Northern areas to 1,400 kWh/m2 per year in southern areas. We have revealed their main advantages and disadvantages of solar photovoltaic power plants, as well as the purpose, basic features, features selection and operation of inverters and batteries. We have also given a generalized block diagram of three types of solar photovoltaic power plants: autonomous, standby, network. The peculiarities of their work have been presented. To improve the reliability of operation of solar power plants we need to design them according to the modular principle. Modular aggregation has to be applied for stand-alone inverters, where the input and output filters, power electronic circuit and system voltage regulation and protection represent the functional module elements. It is possible to increase significantly the reliability of autonomous inverters and solar PV systems in the complex, using one-phase and three-phase transformers with rotating magnetic field in their design. The advantages and the disadvantages, the peculiarities of the solar PV plants discussed in the article will allow to develop their structural and circuit designs with improved maintenance characteristics in the future

01.00.00 Physical-mathematical sciences
DescriptionWe consider the methods for estimation of the effectiveness and quality of the scientific activities of the researcher, of the organization, of the magazine. Performance indicators of scientific activity are used as an important part in the estimation of higher education institutions, the innovative capacity of enterprises, etc. To estimate the effectiveness of scientific activity is natural to use intellectual tools which are well-established in other subject areas. This will include, in particular, the balanced scorecard, based on key performance indicators (hence the title of this article), as well as controlling, primarily controlling of research activities. There are two more developed and widely used types of tools for estimation the effectiveness of the scientific activity - the scientometric indicators and the expert estimators. Their critical analysis is the subject of this article. The goal - to choose the most effective tool. Different versions of manipulating of values of scientometric indicators in the Russian Federation, in our estimation, are still relatively rare. Perhaps this is due to the relatively short period of their use in the management of science. Since an indicator such as citation index (the number of citations of publications) of researcher, allows estimating its contribution to science, the use of this scientometric indicator for the management of science is justified. At the same time, the number of publications and especially h-index is not possible to objectively estimate the effectiveness of research activities, particularly in view of the properties of the real bibliometric databases. Expert procedures have several disadvantages. In this article we discuss the real effectiveness of expert procedures in the areas of their application, as conferring academic degrees and elections to the National Academy of Sciences (primarily in the Russian Academy of Sciences), as well as appointments to senior positions. The basic principles of expertise in these areas remain the same for the past 70 years. Based on an analysis of practice it is necessary to ascertain the lack of efficacy of expert estimators in these areas. Rationale to what has been said is given in the article

Description
There was shown the necessity of achievement of criterion of food safety of the RF. There were formulated the main aims and tasks of state agrarian policy of Russia. There were appeared the main tasks of the Doctrine of food safety. There was given the characteristic of qualitative condition of Krasnodar region lands – liability of erosion processes, decrease of humus content. There was proven the first-priority necessity of transition from zonal system of land management to adaptive-landscape one. The theory of adaptive-landscape was determined as a basis of innovation technology of agricultural commodity production growth. There was formulated the problem of development of methodology of ecologicaleconomic justification of the transition of the agricultural sector of the region to the adaptivelandscape system of agriculture. Using GIStechnologies there were used the areas due to types of lands and degrees of erosion processes in limits of three natural landscapes. There were cited the naturalclimatic, soil and ecological peculiarities of natural landscapes I, II, III. There were offered the ecological coefficients additionally characterizing the types and degree of erosion processes. There was calculated the ratio of lands – arable lands: forest: meadow in limits of natural landscapes. There was done the ecological –economic assessment of arable land crop rotation recommended by the “System of land management of Krasnodar region” in 2015. Recommended for natural landscapes field crop rotations per 1 ha of arable land provide the annual value of gross output of 32.3 - 37.0 thousand rubles, net income - 11.5-12.9 thousand rubles, the levels of profitability - 52.4-55.4 per cent. The proposed crop rotations provide a positive balance of humus. Further studies are needed to clarify the methodology of design of adaptivelandscape farming systems, the development of fodder and special types of crop rotations, agrocomplexes design of erosion control measures, differentiated by natural landscapes and agricultural landscapes, considering the type and intensity of erosion processes are required

EXPERIMENTAL STUDY OF NOISE AND VIBRATION OF THE BAND SAW FRAME SAWS AND WOODWORKING MACHINES
DescriptionThe article presents the results of experimental studies of band noise generation and multirip woodworking machines. The studies have shown that saw woodworking group, as well as metal, are general patterns in the formation of the spectral composition that allows to approach the development of practical recommendations to reduce sound pressure levels in the work area to the operators of sanitary norms. Of particular note is the fact that elevated levels of noise generated by the cutting tool. The effect of changes in process parameters, in particular, the depth of cut and feed to levels of noise generated by the tool. For example, increasing the depth of cut in half leads to an increase of sound pressure levels at 5.8 dB (theoretically obtained value is 6 dB), and supplying a halving of the sound pressure levels reduces by 5 dB. High enough for engineering purposes convergence of theoretical and experimental sound pressure levels and the fact that the calculated values above experimental, allows the calculation and design of the system to reduce the noise under consideration in the machine is, only in service but also in their design

ELECTRICAL CONDUCTIVITY OF IONEXCHANGE MEMBRANES IN SOLUTIONS CONTAINING CARBOXYLIC ACIDS
DescriptionThe article presents the experimental results of the study of the concentration dependence of the electrical conductivity of heterogeneous ion-exchange membranes that are in contact with solutions of weak electrolytes - carboxylic acids. It is shown that in this case the membrane conductivity is higher than the conductivity of the solution, wherein the conductivity of cation exchange membranes substantially greater (by an order of magnitude) than the conductivity of anion exchange membranes. This fact must be considered when designing the actual electrodialysis processes of processing solutions containing organic ions. The work identified the need to develop modern ideas about transport and the structural organization of ion-exchange materials, to describe the structure of the ion-exchange membranes that are in contact with weak electrolytes solutions
