Prognosis of industrial results of some or other agro technologies application and support of decision taking by choice of such varieties of grains and rational agro
technologies for their cultivation, which with
most probability would show the given desirable
industrial result in advance are cited in the article.
The phenomenon of electro convection in membrane systems is of considerable interest, because it is, according to many authors, the main mechanism of overlimiting mass transfer. A great number of theoretical and experimental works, in which, as a rule, dimensional values were used, are devoted to electro convection study. Because of that, in actual fact, there is investigated the influence of individual factors on the transfer process. For example, the influence of voltage jumps, the average speed of a forced stream of the solution, the geometric characteristics of the channel, the initial concentration, etc. However, the influence of these factors appears not separately, at the same time. Thus, there is the problem of introducing dimensionless complexes of dimensional values that have a physical meaning and that allow to evaluate the inner links of the process. As it is known, for solving that problem, there is applied a theory of similarity, based on the transition towards dimensionless parameters in equations and formulas describing the process, and using values, typical of the system under study. This work is devoted to the determining of physical meaning of similarity criteria of salt ions processes, taking into account electro convection in the desalting channel of electro dialysis apparatus. The channel is bounded with perfectly selective, homogeneous anion-exchange and cation-exchange membranes. The introduced similarity criteria are used so as to conduct the theoretical study of the effect of a number of parameters of a desalting process on electro convection
The 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

The 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

The article analyzes reasons that prevent the formation of stable and effective AIC associations of commodity businesses and processors of raw materials. Unbalanced process of the relationship between agricultural producers and processing plants have a negative impact on the economic situation of the organizations partners. Dictating low purchasing prices for raw materials by processing enterprises hinders profitability of agricultural producers. Purchase prices set by the processing enterprises of the dairy industry for milk, do not compensate for not only the production costs but also the losses from inflation. The rate of growth in energy prices is significantly higher than for livestock products, bringing its cost grew faster than sales prices. This leads to a dramatic reduction in milk production profitability. A paradoxical situation: on the one hand, dairies are facing an acute shortage of raw materials, on the other - exacerbated the problem of the sale of its milk producers at a reasonable price for them. The disparity between the purchasing prices for milk and retail prices for dairy products caused agricultural companies to seek alternative markets. Sharply increased sales of milk in the bottling of milk tankers, while many farms began to create their own recycling system
