Description
The research is devoted to the problem of choosing the best methods for assessing the economic efficiency of information technologies. Using the Kemeny median is proposed to solve this problem. This method will allow to obtain the ranking of methods of evaluating of IT effectiveness by various criteria. The existing methods of valuation of economic efficiency of information technology were systematized in the article. Preliminarily, all the methods were divided into three groups: financial, probabilistic and qualitative analysis tools. The advantages and disadvantages of methods, their purpose, use and limitations were also considered. As a result of systematization, it was concluded that there were some limited and one-sided methods. No single method allows to assess comprehensively the effectiveness of an information technology. Obviously, the methods should be considered in the system. But for this they need to be ranked. In order to obtain the ranking the method of Kemeny median was used. In the beginning the expert evaluation of methods by the eight proposed criteria (taking into account the specificity of the original data, validity, unambiguity, information content, exactness, complexity, the access to information, the cost) was carried out. Next, the search of the group ranking was carried. The matrix of losses was compiled. The problem of appointments was solved in MS Excel. At the end, the matrix of paired comparisons has been obtained. This matrix helped to determine the final ranking of alternative methods. Therefore, using the Kemeny median allowed us to prioritize the use of methods of evaluating of the effectiveness of information technology

MICROSTRUCTURE OF MODEL SYSTEMS BASED ON FERMENTED RAW MATERIALS
DescriptionIn the research we have given a detailed description of certain structural components of the model system when adding fermented raw material into it. As the raw material we used collagen containing by-products of bovine animals of the 2nd category – lips and ears were used. The lactulose syrup and linseed flour were used as growth-promoting substances. The fermentation of the raw material was conducted by freeze-dried starter of the bacteria of Propionic Culture PS–4 and Probio–Tec ВВ–12, and also bacterial concentrate Bifilact-Pro. The fermentation parameters: the temperature 37°С, the time of the fermentation is 3 hours. The changes, taking place in the tissues under the biotechnological processing, were established with the method of the histological samples test. As the result of the conducted microstructure tests of prototypes it was determined that in the biomodification process under the influence of the propionic and bifidus bacteria marked changes occurred in the histological structure of modeling systems in the comparison with the control sample. At the same time it was ascertained that under the influence of the ferment processing a loosening of collagen fascicles happens to isolated fibrils and their fragmentation occurs. As the result, when composing protein compositions an emulsion (which is homogeneous by the structure) comes out. In the future it is recommended to use the emulsion in the receipts of boiled sausages and minced half-finished goods

STRATEGY OF GROWTH FOR THE CRISIS MARKETS ON THE BASIS OF CONTROLLING OF INNOVATION
DescriptionThe article is devoted to the problem of "How to grow in crisis conditions". In the article it is reasoned that without innovative development of economy progressive functioning of the companies is impossible, the country won't be able to compete with other states on the international commodity market and services. On the basis of controlling of innovation there are conditions created for long-term prospects of the company and expectations of all the stakeholders. Public crisis is generated by conditions and contradictions inherent in it. Their understanding and judgment, creative permission are the key prerequisite of transformation of the companies seeking the way "to fit" into new reality

MATHEMATICAL MODEL OF THE DYNAMICS OF HIV INFECTION WITHOUT TREATMENT
01.00.00 Physical-mathematical sciences
DescriptionThis article discusses the mathematical and numerical modeling of the immune system of the course of HIV infection without treatment. Presently a significant number of scientific papers are devoted to the study of this problem. However, HIV infection is highly volatile and there is no effective drug, in that HIV has the ability to mutate and reproduce itself in the presence of chemical substances that are meant to inhibit or destroy it. The mathematical models used in this paper are conceptual and exploratory in nature. The proposed mathematical model allow us to obtain a complete description of the dynamics of HIV infection, and also an understanding of the progression to AIDS. Thus, the results of the numerical solution of differential equations in this work show that: the disease develops, and at low concentration of the virus, a certain level of stability does not depend on the initial concentration of infestation. In the absence of treatment, for interesting competition between virus and the loss of virus caused by immune response should be strictly greater than the rate of multiplication of the virus in the blood; the reproduction rate of the uninfected cells should be stricly greater than the mortality rate of the uninfected cells

Description
Creation of a new educational institution is always a big event. However, educational institutions do not use to appear in a spontaneous and unexpected way. Such appearance requires public necessity and expedience. In this very way, the institute of veterinary was created in Vitebsk in its time in 1924 and later transformed to Vitebsk State Academy of Veterinary Medicine which became one of the leading higher schools in this industry in USSR and the only educational institution in this specialty in the Republic of Belarus. The article covers such aspects of the academy work as involving students in the scientific activities and the book culture. Another issue of the article is development of auxiliary departments, such as economics, politology and philosophy, economic history and theory, computer literacy, the work of which make an indispensable contribution to education of a comprehensively developed specialist capable of professional growth and improvement. Vitebsk State Academy of Veterinary Medicine, with due regard for the experience accumulated by it, is the leader in formation of highly educated and skilled specialists in the field of veterinary medicine and biotechnology and in training of comprehensively competent experts as well, who have got noble moral and ethical principles and obtained substantial knowledge in humanities, who can convert this knowledge from theory into practice as appropriate

Description
The article contains the estimation of effectiveness in the use of by-products, cameline-seed oil and amaranth flour in the meat by-products in the dough. By-products were used for the purpose of the expansion of the assortment of the meat semi-finished products in the dough. Amaranth flour was introduced for the purpose of an improvement in the organoleptic and functional- technological characteristics of the stuffing and an increase in the quantity of protein. Cameline-seed oil was added for the purpose of the enrichment of product by omega- acids. As the experimental models we have made pelmeni (ravioli), the relationship of dough and stuffing in which comprised 1:1. In the prototypes the flour from the amaranth was introduced in quantity 5, 10 and 15%. Cameline-seed oil was introduced in quantity 2%. Models with the amaranth flour in quantity 5% had the smaller output of product and the insufficient moisture-binding ability. Models with the content of flour from the amaranth in quantity 15% had the strong smell of plant component. Experimental model with a quantity of amaranth flour 10% on the organoleptic characteristic proved to be best, and there composition was acknowledged most optimum. The studies of the experimental models of meat semi-finished products in the dough showed that the use of amaranth flour contributes to an increase in the moisture-binding ability of stuffing, to an increase in the output of product, to an increase in the content of protein and irreplaceable amino acids. According to the results of all conducted studies is made the conclusion that flour amaranth can be used as the moisture-binding component for making of meat semi-finished products in the dough

Description
The article provides an overview of the phytosanitary condition of crops for 2011-2014 g in the Krasnodar region. In recent years, we can observe increasing of the crop losses from pests and diseases of plants. The using of different pesticides in intensive cultivation technologies of winter wheat can’t resist this. Pathogenic microorganisms acquire resistance to drugs used and become more aggressive. This creates a lot of environmental problems. Plants are almost always under environmental stress. However, it is impossible to refuse of pesticides. And they are not able to observe the immune system of the plant, and in some cases inhibit it. The present level of development of science has led to the emergence of new methods of plant protection, which is based on increasing of the capacity of the immune plants, rather than the destruction of pathogens, as in the case of the use of pesticides. We propose to apply so called "agrochemical cocktails"

The problem of correlation of senses and notions in the science, their substitution and the birth of so-called pseudo knowledge is the issue which is more than ever burning in our times of perturbations and big changes. Biological sciences could not avoid these problems as well. All the more so because they stayed for many years under significant pressure of the ruling ideology of those times, of the state and of the governing party machineries. That is exactly why Darwinism as such requires a profound analysis in terms of contemporary achievements of the science, inclusive of philosophy. The analysis of knowledge which is available now and has been accumulated for many centuries of development of the biological science allows finding logical contradictions, possible substitutions of sense platforms, i.e. the birth of pseudo knowledge, which needs to be ascertained and suppressed. The appearance of such branch of the science as biophilosophy exceedingly aggravated the situation due to a number of big methodological shortcomings of this branch which still remains to be a non-science. As it cannot facilitate studying the organic world and, the other way round, even confuses such studying by applying an anthropomorphous matrix to the world, while the ethic and the aesthetic cannot only be attributed to the human mind, the situation becomes pretty complicated. At the same time, the philosophic envelope of the biological science is often filled with various kinds of ideology which makes no contribution to the objectivity of knowledge
