THE STUDY OF SELF-BALANCED POTATO SORTING MACHINE WITH LINEAR INDUCTION DRIVE
DescriptionIn the article we have considered the self-balanced potato sorting machine differing from existing designs of self-balanced potato sorting machines with an oscillatory electric drive. That drive uses a linear induction motor. As the counterbalancing device, the method of the duplicating mechanism is applied. The duplicating mechanism is a specular reflection of the main working body, and also participates in technological process. Its application in the drive of machine allows not only to increase efficiency of cleaning, drying and sorting of potatoes, but also to increase reliability of sorting installation that corresponds to the newest tendencies of development of technology. We have brought the mathematical model of the offered electric drive of potato sorting machine, which is implemented in the environment of object and visual modeling of Matlab |Simulink|. The mathematical model allows investigating influence of parameters of the linear induction electric drive on parameters of oscillatory process of working body in dynamics. The developed technique of research and the created experimental potato sorting machine with the linear induction drive have confirmed theoretical researches. The main kinematic sizes of machine and technical parameters of individual nodes are determined. It is shown, that the efficiency of inertial transportation can be increased for 20% in comparison with the classical drive from the motor of rotation. Results of research will allow to realize energetically and technologically effective potato sorting machines with the linear induction drive

STUDY OF THE INTERACTION OF POLYSTYRENE-AZO-O-PHENOL-AZO-RHODANINE WITH ZINC IONS AND CADMIUM
DescriptionSince the industrial revolution a huge amount of pollutants emitted annually into the water most of which is occupied by toxic metals. These metals widely distributed in the environment and of accumulation of a threat to human health. It is known, that cadmium and zinc at high concentrations have a negative impact on nature. In modern wastewater treatment technology we widely use polymeric sorbents with chelating properties. The use of polymeric chelating sorbents (PCS) usage allows separating individual or group trace elements from large volumes of solutions of complex composition, lowering the limit of detection, eliminating or reducing significantly the impact of macrocomponents which increases the cleaning efficiency. The article presents the results of a study of conditions of interaction of zinc (II) ions and cadmium (II) with PCT - polystyrene-azo-o-phenol-azo-rhodanine. We found the optimal values of the conditions for zinc (II) ions and cadmium (II) sorption. We investigated the effect of interfering of the macro- and micro- water components with the sorption of the ions studied. Maximum desorption of metal ions is achieved by washing the concentrate with 10 ml of 2M hydrochloric acid. The data indicate availability of the investigated sorbent for concentration and separation of zinc (II) ions and cadmium (II)

TO THE ANALYSIS OF DEVELOPMENT OF PEASANT AND PERSONAL FARMS OF THE POPULATION
DescriptionSmall agrarian and personal peasant farms present an important segment of agricultural production along with other subjects. Their role is becoming more prominent with the increasing of their own production potential. Nevertheless, their resource base remains very weak, the basic means of production are worn out, and many of them are unable to improve technical equipment. In this segment, leasing options are limited, there are problems in logistics management, and small entities do not have market power in the market of production resources and in products marketing. The lack of collateral generates high cost lending and permanent bankruptcy. On the other hand, it is noted that small entities have a large diversity of organizational and legal forms, an informal control system high interchangeability of production functions, they combine the status of the owner and the manager. They significantly reduce the social tension in rural areas; they play a significant role in import substitution. Characteristic features of small agricultural farms (SAF) are high autonomy, independence, self-protection from environmental factors. They spend little money on creating jobs, have low fixed costs and independently overcome the difficulties. However, an underdeveloped industrial infrastructure of small business hinders the improvement of the technological level. They work with constant external interference, which reduces their production efficiency and market competitiveness. All of them highly depend on local production conditions, capacity of territorial markets. Low level of cooperation of participants SAF significantly limits the number of sales channels, increases the volatility realization. The analysis showed a high need for realization of the revealed reserves of efficiency growth

Description
The reasons for the development of Protestantism in the South of Russia in the late XIX - early XX centuries are discussed in this article. Standpattism is spreading among the population of southern Russia. The ranks of the Protestants were replenished with the social strata associated with the development of capitalist relations in town and village. The emergence and development of Protestantism is an important feature of capitalization and Europeanization of Russia. By the beginning of XX century the Baptists are widely distributed throughout the South of Russia. In the late XIX - early XX century the process of converting from Orthodoxy to Protestantism of Cossacks was observed in the South of Russia. The article also researches Russian Protestantism – the old belief. In 1883 it became possible the old believers' worship. Russian Protestantism gained almost full rights

TO THE QUESTION OF ECONOMIC DEVELOPMENT IN FORMATION OF THE SINGLE ECONOMIC SPACE
DescriptionModern trends of development of economic relations are not devoid of problems. The globalization of economic relations, development of communication network has opened a lot of abuse, incorrectly built relationships with contractors and agencies administration, well-known difficulties and shortcomings of law enforcement. The study showed that the weight of these circumstances caused the absence of an organized system of registration, formation, compilation, analysis and presentation of information. Collectively it is nothing like the attributes of the accounting system. The development of accounting in the region and the country as a whole in the direction of generalization of accounting information on all economic entities and other economic actors, becomes the requirement of time. The authors proposed the principles of the organization's user systems through a single automated account management system. Defined the functional role of each participant in such system. Much of the information comes from the so-called user agents – the authority of the state machinery and economic entities authorized in the formation and presentation of the required accounting information. The rules of the proposed system will provide the consistency required functionality of each participant and access to some form of economic information through economic roadmap. The implementation of the proposed accounting system will allow to define rules of functioning of the uniform economic space of the country, which will make possible the implementation of economic policies more effective, will allow to disseminate the experience of effective ministries in all areas of economic space

ON QUESTION OF ESTABLISHING THE TAX OF INTERNET-SHOPPING IN RUSSIA
DescriptionCurrently, there is a topical question of legal consolidation in the tax and the customs legislations of the fee for goods purchased from a foreign company through a transaction concluded by the information and telecommunications network "Internet". According to the legislator, such innovations will limit the spillover of online orders to the neighboring states with a high threshold for duty-free shipping, which will strengthen the domestic e-commerce market. The authors believe that the consolidation of the institution in the national legislation would contradict the general provisions of tax legislation. The authors believe that such measures will increase the number of sham and mock transactions and reduce import turnover. The proposed projects of the European Economic Commission of the European Economic Union on the Internet fees in their structure are poorly written, in particular, they lack the concept of internet purchase, there is no resolution of the issue of the relationship between the collection and the value added tax.The authors come to the conclusion that these projects should to be completed, in particular, it is proposed to supplement the provisions of domestic legislation, delimiting the object of taxation the value added tax on the object of taxation for cross-border fee to be paid for an online purchase. Their immediate implementation without significant changes will not create a proper mechanism for the implementation of this institution, and generate a lot of conflict situations

Description
The main reason of the developmental delay of the RF livestock sector below the level of its inherent potential capacity is a detrimental alteration in methodological procedure of livestock and poultry management, occurring due to shortage of traditional feeds. As a result, a necessity to develop the yearlong production of additional fodders, allowing for balanced feeding throughout the year, arose. The method of hydroponic green fodder (HGF) cultivation meets these requirements. Analysis of HGF production methods and labor saver mechanisms makes possible to claim that existing systems are characterized by high costs and difficulties in fabrication, and require a number of additional mechanical devices to work. In the FSBEI HE “KSMTU”, a one-tier hydroponic system has been developed, fitted with curved (arched) guideways and rigid elastic load-carrying components, where loading of seeds and takeout of grown HGF occur by gravity without additional devices of labour input. Based on analysis performed on design features of the proposed system, it has been established that emergence of parametric resonances in the system under consideration is possible; and the study of tray dynamical stability has been carried out with the aim to prevent them. The motion of the hydroponic system tray under consideration is described by the classical Mathieu equation, including two parameters a and q. The further studies of sets of stable and unstable solutions in the plane of a and q parameters are presented by the Ince-Strutt diagram. As a result of the performed calculations, the diameter of the loadcarrying component was identified (d=5 mm), which should ensure reliable working capacity and stability of the hydroponic system in whole

THE COORDINATES OF THE POINTS BACKWARDS THE ANGULAR NOTCH
DescriptionEven with the modern development of geodetic techniques to abandon traditional ways a condensation of planned networks is not possible. Therefore, the article describes the case of determination of coordinates of points using backwards the angular notch and the accuracy of their determination. In the classical methods of solving the backwards the angular notch are calculated coefficients, and get the coordinates of the designated point. The authors propose to use auxiliary angles that will reduce the amount of calculation. In addition, the article gives examples of solutions to well-known formulas of Gauss and through the calculation of direct geodetic purpose

Description
The article presents the criteria for evaluating the integration of researchers in the scientific community, based on an analysis of its citations. It is known, that one of the major components of interscientific communication (communication in the scientific community) is a citation of scientific publications (monographs, articles, etc.). According to the sociological approach, a scientist is a part of society, ie, scientific community; under scientific community we understand scientific mega environment (opposed to research groups of institutions and their structural units). Integration of a researcher to the community has many aspects: on the one hand, it is - the importance of his work to the scientific community, on the other hand, it is - the use of a scientist social mega environment for building for their personal and professional development to improve their research and improve the quality of its results (in the context of the article we will consider the second aspect). Methodological bases of the research: systematic, competence, sociological, and mega-system qualimetric approaches. Methods: modeling, methods of quality control, methods of set theory, relations and graphs. Evaluation (diagnostics) involvement of scientists in the scientific community - is more complicated metrology task than the evaluation of the significance of the results of its research activities. For the authors it is clear that a mature scientist (with a high level of research competence) should intensively use the potential of the social and the cultural science international environment (community) for their personal and professional development, to improve the efficiency of this research activities and the quality of this results. The proposed indicators can be considered as group indicator variables reflecting the level of the behavioral component of the research competence (scientist). Using social media for researcher’s potential – it is necessary, but not sufficient condition for productive research, producing goodquality scientific results. In this situation, negative prognosis is more significant: poor use of social media for researcher’s potential – is a "guarantee" for low productivity of this research activities and the low quality of this results. Only the combination of the highest levels of readiness for research (research competence) with high levels of other competences (as a whole - the social and professional competence, implying the presence of the professional skills of selforganization) can be the factors of successful research
