01.00.00 Physical-mathematical sciences
DescriptionWithout science it would be impossible to form a full environmental consciousness. To increase the validity and weight of the findings on the impact of environment on quality of life, it is necessary to quantify the strength and direction of the influence of diverse environmental factors. However, it appears that this is quite problematic for a number of reasons. First, it is the lack or inaccessibility of source of data which is necessary for such type of research. The same data, which still can be found cover just small periods of observations (small longitudinal research data), and their completion, including performing experiments, is fundamentally impossible. As a result, it is impossible to require such full data replications, which is a necessary condition for correct applying of factor analysis. Secondly, environmental factors are described with heterogeneous indices measured in different types of measurement scales (nominal, ordinal and numerical) and in different measurement units. Mathematical methods of comparable processing of such data, and the right software tools for these methods, generally speaking, do not exist. Third, these tasks are large-scale problems, i.e. they are not talking about 5 or max 7 factors as it was in factor analysis, but about hundreds and thousands. Fourthly, the original data is noisy and require sustainable methods. Fifthly, environmental factors are interrelated and require nonlinear nonparametric approaches. To solve these problems it is proposed to apply a new innovative intelligent technology: automated system-cognitive analysis and its software tool – a system called "Eidos". We have also given a brief numerical example of assessing the impact of environmental factors on life expectancy and causes of death

MATHEMATICAL MODELING OF ELECTROCONVECTION IN THE CAPILLARIES. TRANSIENT BEHAVIOR
01.00.00 Physical-mathematical sciences
DescriptionWe propose a mathematical model of ion transport binary salt in electroosmotic flow in a capillary. The capillary is open on one side and immersed in a vessel of large volume, in which the concentration of the solution is maintained constant, and the other side closed ion exchange membrane. The walls are considered wettable, i.e. the solution adheres to the walls. This means that the mathematical modeling used to rate the condition of sticking. We study the boundary value problem for a coupled system of equations Nernst, Planck, Poisson and Navier-Stokes equations. Used boundary conditions of general form. The mathematical model is based on the general laws of transport and contains no adjustable parameters. Using this model, the basic laws of ion transport salt solution liquid flow, the emergence and development electroconvection, distribution of concentration of salt ions in the capillary with a small change in time, ie, in the initial (transitional) regime. We have identified the presence of ion-exchange membrane surface electroconvective vortices and their influence on the mechanisms of ion transport of salt and fluid movement in different areas of the capillary. A feature of the capillary transport is to the right of the vortex region stagnant areas with a higher concentration of ions

FINANCIAL AND ECONOMIC ANALYSIS OF AGRO-INDUSTRIAL COMPANIES OF FOREIGN AND DOMESTIC MODELS
DescriptionThe article provides a detailed overview of the existing foreign and domestic models of analysis of financial and economic state of companies; we have identified their strengths and weaknesses in relation to the Russian agro-industrial companies. We have also conducted an experiment in which we analyzed 70 enterprises of the agroindustrial complex using the following ten methods: E. Altman’s, the model of R. Taffler and G. Tiso, the method of “credit-men”, the model of Springate, the models of Fulmer, the Fox model, the model by G. V. Savitskaya, the model of P. O. Zaitseva's, the models of Sberbank, the models of ISEA. The choice of these models is associated with their popularity and ability to use for the analysis of financial and economic state of companies of agroindustrial complex. The experimental results allowed concluding the fact that for whatever reasons, the existing methods are not always suitable for effective analysis of financial and economic state of enterprises of agroindustrial complex. It is therefore necessary to seek some new approaches and to develop a modern model focused on the analysis of financial-economic condition of agricultural enterprises. The practical significance of this study is that the identified problem is the lack of analysis models able to carry out an adequate assessment of the economic and financial condition of agricultural companies

EFFECT OF ELECTROMAGNETIC FIELD LOW FREQUENCIES IN THE TECHNOLOGY OF DRYING MANGOES AND PAPAYAS
DescriptionThe intensity of drying process depends on the speed of movement of the moisture inside the object and the speed of its removal from the surface. To accelerate the drying process, temperature gradient is often regulated, which causes large power consumption. Currently, they are different methods in used for intensifying the process of drying of plant material which are physical, mechanical, chemical and electrical method. Data of literature review show a lack of data on the impact of synergies of lower frequency on the efficiency of drying plant material. Accelerating the drying process of fruit can be achieved by combining low – temperature of drying with a synergistic lower frequency of electromagnetic field. The results of the studies on the development of technologies to accelerate the drying process of mango and papaya fruit are presented in this article. The role of the electromagnetic field, on the intensification of the drying process and on the inhibition of the microflora of mango and papaya, during drying is studied. Effect of the synergistic electromagnetic fields of different frequencies leading to the death of microorganisms, as well as the drying rate of mango and papaya fruit is analyzed. The optimal technological parameters of low frequency electromagnetic field on drying of mango and papaya fruit are determined. Biochemical changes of mango and papaya fruit during drying are given. Technological parameters of the powder mango and papaya obtained by combining low temperature treatment with the synergy of low frequencies are described

MODEL OF MULTIVARIATE FUZZY TIME SERIES FORECASTING OF ENERGY LOSSES
DescriptionNowadays the high level of electricity losses is one of the most important issues of the energy industry in the Russian Federation recognized at the state level. According to many sources, one of the activities that contribute to reduce energy losses, is their planning, an important component of which is the prediction of electricity losses on the basis of retrospective information. The highest percentage of technical losses of electricity is accounted for distribution network with a voltage range 0,4-35 kV. In this regard, the most productive activity is forecast construction namely of this component of power losses. According to some features of the regarded value (electricity losses) the most effective activity for its forecasting is using methods with artificial intelligence elements. One of these methods, having a number of important advantages, is forecasting fuzzy time series. This technique is widely consecrated in foreign publications, but did not find sufficient popularity in our country. This article analyzes the existing models of forecasting fuzzy time series on the basis of which proposals for their improvement and adaptation in order to predict the loss of electricity are made; designed model of multivariate fuzzy time series forecasting of energy losses is given

MICROBIAL COMMUNITIES OF KARPOSPHAERA AND PHILLOPLAN OF SOME PLANTS OF GROSSULARIACEAE FAMILY
DescriptionThe article presents the results of the research of microflora composition of the leaf surface, the surface of fruit and flowers of Ribes nigrum, R. niveum, R . rubrum and Grossularia reclinata. The research was carried out in the seasonal dynamics from 2007 to 2014. The authors used the method of print for isolating microorganisms from plants. For convenience of calculations and contamination comparison of different environmental niches of plants the number of selected microorganisms was counted on the surface of 1 cm2. It was found out in the article that microorganisms on the surface of lamina are distributed unequally. The number of microorganisms on the bottom surface of the foliage in all periods turned out to be higher. The greatest number of microorganisms was recorded in autumn and reaches the highest value in October. The number of microorganisms on fruit surface increased with ripening and was the highest in July. The quantity on the flowers varies considerably throughout the flowering and is represented minimally compared to other plants niches. The study revealed species-specificity of microorganisms and the host plants. At the same time, long-term study of the microflora of plants belonging to one family made it possible to reveal species that are typical epiphytes

AUTOMATION OF BUISNESS-PROCESSES OF A TRAINING CENTER
DescriptionThe modern Russian companies have realized the need of automation of document flow not only as a mean of keeping documents in order, but also as a tool of optimization of expenses, as an assistant in adoption of administrative decisions. The Russian market of information systems for long time had no software products intended for educational institutions. The majority of the automated systems are intended for the enterprises with an activity in the sphere of trade and production. In comparison with the above companies, the list of software products for commercial training centers is small. Even considering the developed line of programs it is impossible to speak about meeting all the requirements for companies of such activity. At creation of the automated system for training center, the analysis of the existing software products intended for automation of training centers and adjacent institutes was carried out; a number of features of activity are revealed. The article is devoted to the description of the developed automated information system of document flow of a commercial educational institution, namely the developed configuration of "Training center" on a platform of "1C: Enterprise 8.2". The developed program complex serving as the administrative tool for the analysis of economic activity of training center, scheduling of the educational equipment and teaching structure, payroll calculation taking into account specifics of branch has been presented in the article

Description
This article is devoted to solving the critical task of improving the reliability of the power systems for agricultural processing plants. The article’s material is exploratory in nature, reflected in the fact that the proposed mathematical models for the analysis of groups of high-voltage induction motors will allow to investigate various modes of symmetric groups of asynchronous motors more effectively. We present the analysis of the existing mathematical models of induction motors considering the design features of such machines that directly affect the dependence of resistance and inductance on the rotor current frequency. The assumptions taken into consideration to obtain a more accurate mathematical model of the induction motor are also formulated. The article provides a comparison of different reference frames used in the mathematical modeling of asynchronous motors. It is proved that the use of the generalized coordinate vector for mathematical modeling of asynchronous motors is the most optimal approach. The equivalent circuit of asynchronous deep-bar motor in generalized vector coordinates derived in the work is used for analysis of transient behavior as well as the steady state operation. The results of the study are suitable for transient analysis of electrical power supply systems of agricultural enterprises with large number of high-power electric motors, for example, CHP of sugar processing plants and grain elevators

LEGAL SUPPORT FOR PUBLIC CONTROL: PROBLEMS AND PROSPECTS
DescriptionIn the article we reveal the basic problems of forming the legal basis of public control over the activities of public authorities. The relevance of this topic has been steadily increasing due to the increasing influence of civil society on the decisions made by public authorities. The authors analyze the provisions of the Federal Law "On the basis of public control in the Russian Federation", the regional laws, to fix the foundations of social control in some subjects of the federation, as well as other legal acts in this area. Special attention is paid to the formulation of the concept of social control and the conclusion of the need legislative consolidation of the concept of "individual public authority 'and a common list of agencies and organizations that operate them. Analyzing the law enshrined in the range of subjects of public control, the authors substantiate the feasibility of incorporating the Advisory Board at the government and public experts. On the basis of the provisions of the law, in this work we have determined the legal status of the subjects of social control, their powers and procedures of the in collaboration with the authorities, as well as the legal framework for the implementation of certain forms of social control. It is proposed to expand the interaction of subjects of public control with prosecutors by holding regular meetings to expand the powers of public monitoring commissions for visiting places of detention
