Description
The article compares various hypotheses that explain the mechanisms of the influence of the magnetic field with different characteristics on liquids, physico-chemical and biological systems. Physical effects that cause specific biological activity of water (magnetic treatment of water, production of thawed water, degassing, etc.) make water be metastable or non-equilibrium states. Water attracts the attention of researchers as a likely universal mediator in the transmission of electromagnetic field signals to the biological level. Water is involved in a variety of chemical and metabolic reactions, so the question about the ability to change the properties of water and solutions under the influence of fields of different nature: an electromagnetic field with different frequencies, with different combinations of field orientations (parallel constant and variable magnetic field, slope fields, rotating magnetic fields, magnetic fields close to zero and electric fields) arises. At the heart of existing methods for treating liquids lie methods that use the energy of the acoustic and magnetic fields, as well as complex methods of influencing the electromagnetic field in combination with thermal heating, pressure change, etc. The analysis of existing hypotheses about the mechanisms of the influences of fields of a different nature on the treated liquid makes it possible to put forward a hypothesis about the possibility of the joint influence of the acoustic and magnetic fields on the liquid by means of the acoustic and magnetic device

Description
The integration of producers of raw materials and its processors into the agro-industrial complex is connected with the social division of labor, its specialization, the need for interaction between specialized branches and types of agro-industrial production. Agrarian enterprises are united in an effort to reduce the risk, the emergence of which depends on the climatic conditions, the spontaneity of the agricultural market, the dictates of processing enterprises, the need to increase the competitiveness of production. In the Russian practice, there were various organizational forms of integration, differing in the nature of economic ties between participants, the degree of independence of the enterprises entering the association, the combination of centralization and decentralization of management. Conventionally they are divided into associative - "soft" and corporate - "hard." The "soft" forms of association include as-association, union, non-profit partnership and strategic alliance. They can effectively function at the interregional level. A rigid type of integration ties is characteristic for combines, concerns, trusts, holdings. Agricultural consumer cooperatives are voluntary associations of legal entities and individuals residing or operating in a certain rural area on the basis of membership and pooling of money units in order to meet the needs of members in credit resources and other banks services. The conditions for the emergence of sustainable integrated associations in the agroindustrial complex require qualitative and quantitative analysis based on mathematical modeling

PERFORMANCE MODELS FOR SMALL PROCESSING COMPANIES OF AGRARIAN AND INDUSTRIAL COMPLEX (part 1)
DescriptionThe article proposes a solution to one of the problems of small business, which is creation of a part of the software of management of information system efficiency for small processing enterprises of AIC. The fact is, that currently, there are almost no information systems to support small business. All known information systems have approximately the same list of automated functions, covering the accounting phase, and sometimes phase of analysis. Practically, not affected by the evaluation function of the economic situation, prediction, planning and regulation. The proposed mathematical model has been developed on the basis of the creation of streaming schemes of one-product processing enterprises of agroindustrial complex and mathematical description of the proceeding financial and material flows

Description
The article describes the process of developing the two-level technique for assessment of the missed benefit during the landing and cultivation of perennial plantings. The technique is developed for the enterprises where the cycle of production of raw materials breaks into several periods until the first harvest. The choice problem of the most suitable grades for the landing is relevant for such enterprises. The first level of the two-level technique assumes assessment of qualitative and quantitative characteristics of grades with use of such tools as the theory of fuzzy sets and the decisions tree. The results of the first level are entrance data for the second level where there is final assessment of a grade and determination of the missed benefit rather potentially possible at the choice of the recommended grade. In the article also designated the importance of the raw materials stage for the technological chain. It is shown that, being consecutive structure, the technological chain strongly depends on the first stage – a stage of raw materials production. Minimization of the risk situations at the first stage promotes strengthening of the general risk tolerance of a technological chain

PARAMETERS OF RESEARCH ACTIVITY OF STUDENTS AS CRITERIA FOR DIAGNOSTICS OF EDUCATIONAL ENVIRONMENT
DescriptionThe article reflects the relationship between the parameters of research activities of students and the characteristics of the educational environment in higher education. It is known that the research activity of students is an integral part of the educational process, therefore, the parameters of research activity can and should be indicator variables reflecting certain aspects of the educational environment. According to modern views, all types of research activities of students (educational, research, scientific and practical and research) is the most important mechanism for the development of their research competence. In addition, the parameters of research activities of students - the reflection of the relationship of scientific and educational activities in higher education, and this - one of the most important factors of competitiveness of the educational environment. The authors substantiate that the parameters reflecting the research activity of students characterize, first of all, such aspects of the educational environment as its intensity, social activity, dominance, coherence, mobility, stability, reliability and efficiency. This is due to the fact that the research activity of students is a transdisciplinary process that depends on the same factors as the educational process as a whole and is characterized by the same didactic goals (tasks) as the educational process as a whole. In identifying the relationship between the parameters of research activities of students and the characteristics of the educational environment, the authors also took into account the relevance of such a task as ensuring continuity between levels of continuing education. The theoretical significance of the results of this study is that they can be the basis for further scientific understanding of the problems of the quality of education and the effectiveness of educational environments, the practical significance is that they can be applied in the systems of socio-pedagogical and psycho-pedagogical monitoring and the effectiveness of the educational environment, as well as monitoring the student's personal and professional development). Methodological bases of research: system, sociological, competence, probability-statistical and qualimetric approaches (leading methodological basis - competence approach). Research methods: modeling; methods of graph theory, sets and relations; systemiccognitive analysis; methods of qualimetry (theory of latent variables); methods of mathematical statistics (first of all - the method of rocky scree); methods of the theory of limits

Description
The performance indicators of a trading company in physical and monetary terms is significantly affected by the types and volumes of purchased and sold products, and which she purchased suppliers and the consumers sold. However, the solution to the problem of choosing the rational range of products faces considerable cost of computational and human resources, and lack of baseline data, and in real dimensions this problem has no solution. The paper proposes such a solution is very economical in costs of different types of resources based on the application of information theory, cognitive and control theory

Description
Production and processing of grains formed in the national economic system of the country a number of cereals-governmental sectors, such as grain production, grain elevator industry, flour, cereals and mixed fodder production, which constitute the grain complex country. The significance and role of the grain as a commodity in the state economy can not be overestimated. This product is totally liquid, which has a constant, steady demand at any time of the year, in any region. Ongoing measures to increase grain production and improve its implementation did not have a complex character, therefore, insignificant effect on the efficiency of the industry and the competitiveness of grain production. The shortage was covered by imports. According to the characteristics of management in agriculture, it should be emphasized that the absence of objective and timely information at all stages of production of the plant-breeding, and as a result, non-optimal choice of technology of cultivation of agricultural crops, might result in the fact that the cost of labor and material resources increases significantly, the company does not receive profits, and sometimes suffers losses. When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the process of developing a complex of mathematical models and methods for evaluating alternative technologies for agricultural production (using the example of crop production), their software implementation, and the main scientific results of the project

MODELING AND DIAGNOSTICS OF THE RESEARCHER’S SYNERGIC INTERACTION WITH THE SCIENTIFIC COMMUNITY
05.13.10 Management in social and economic systems
DescriptionThe article presents innovative models and methods to diagnose the researcher’s synergic interaction with the scientific community (social mega-environment). It is known that the researcher’s interaction with the social mega-environment has two main directions: scientific collaboration and using the scientific community’s social and cultural potential; the former appears as scientific publications, while the latter appears as scientific citations. It is also known that synergic interaction is the interaction leading to the increase in activity results (according to the “1+1>2” scheme). In the article, the researcher’s synergic interaction is understood as his/her collaboration-based research activity that leads to obtaining the results impossible without this interaction. The theoretical significance of the research results is in the possibility for the further development of the sociology of science, as well as for the further development of the models of the individual’s interaction with the social environment; the practical significance is in the possibility to analyze the factors contributing to the success in the research activity of academic researchers and research teams (i.e. applicable for monitoring the research activity)

05.13.18 Mathematical modeling, numerical methods and software complexes
DescriptionThe research purpose is identification and justification of the scientific team’s recognition citation-based criteria. Such parameters of the educational environment as modality, latitude, social activity, social coherence, intensity, maturity etc. are assessable on the basis of the primary information about the scientific team’s research activity results. The authors of this article prove that the data about cross-citations within a scientific team is the primary information about the scientific and pedagogical team members’ recognition of their social system (such information is obtainable from modern scientometric databases, e.g. Russian Science Citation Index). The new scientific results of this research are the identified citation-based criteria for the scientific team’s recognition. The theoretical significance of these results is the possibility of using them as a scientific basis for further research in the sociology of science and for the development of the small social systems functioning models; the practical significance is the possibility to analyze the factors for the success of scientific and pedagogical teams’ research activity (i.e. applicability for the research activity monitoring systems). The research methods are: the methods of set, relations and graph theory, the methods of qualimetry, mathematical statistics (including the scree-plot method) and linear. The research methodology is based on the sociological approach (viewing the scientific and pedagogical team as a well-established social system), the qualimetric approach (declaring the necessity for the multicriterial diagnostics of scientific and pedagogical team’s recognition) and the probabilistic and statistical approach (viewing the scientific and pedagogical team’s recognition citation-based diagnostics as a statistic measurement)
