DEVELOPMENT OF ECOLOGICALLY SAFE EXPRESS-METHOD FOR QUALITY EVALUATION OF SOYBEAN LECITHINS
DescriptionThe article presents data, on the basis of which we have concluded that the oil and phospholipids contained in soy lecithins, the degree of unsaturation of fatty acids differ significantly from oil and phospholipids contained in sunflower lecithins, with differences in the degree of unsaturation of fatty acids of oil and phospholipids contained in sunflower and soy lecithins, leads to differences in the content of resonating protons, and, consequently, the level of amplitude values of NMR signals of protons of the investigated lecithins. It is established that the values of the amplitudes of the NMR signals of protons of each of the four components of sunflower lecithins differ from the values of the amplitudes of the NMR signals of protons the component of soy lecithins, which confirms the differences in the composition and content of fatty acids lecithins studied. Considering quantitative characteristic of mass fraction of substances insoluble in acetone, i.e. phospholipids, is the sum of the amplitudes of the NMR signals of protons of the third (A3) and fourth (A4) component, was built the graphical dependence of the mass fraction of substances insoluble in acetone, from the value of (A3+A4)/ASIS, % which is described by the equation (correlation coefficient R2 =0,9911) of the following form: y=0,8177x +2.52. Based on these data, we have developed a rapid method of determining the mass fraction of substances insoluble in acetone, soy lecithin, eliminating the use of toxic organic solvents, is environmentally safe, which is protected by RF patent for the invention

Description
The article presents the use of intensive methods of diet herd reproduction that will increase the productivity and profitability of the sheep industry. One of such methods is in vitro fertilization (IVF). For the success of in vitro fertilization procedure, an important requirement is the availability of highquality nutrient media, which help to preserve the genetic material and contribute to the further development of the zygote. The main requirement to the media for sperm is the ability of media not to cause their agglutination. The aim of our work was to search for new ways to reduce the agglutination of spermatozoa in the preparation of freshly prepared sperm in the process of production of embryos in vitro. To eliminate the agglutination of spermatozoa in the semen preparation stage, we used GCY medium, followed by demolition of seed in SOFw environment, which has resulted in a significant (almost 15 times!) reduce of the number of bound sperm. In our opinion, a decrease in agglutination in GCY buffer was connected with a specific influence of the constituent components of sperm. Conclusion: Thus, our method of preparation of freshly prepared sperm for in vitro fertilization allows a sharp decline in sperm agglutination, which will improve the fertility of eggs during the production of embryos in vitro sheep

Description
According to the title, the article describes the causes and contributing factors of functional disorders of the uterus and ovaries at cows. The authors specified the percentage incidence of these animals’ pathologies in some farms of Krasnodar Region, especially in industrial complexes. Studies have shown that acute postpartum endometritis has a definite influence on the functional disorders of the ovaries at cows. Authors have found that the cows via 2-4 months after calving with ovarian hypofunction in early postnatal period have had purulent-catarrhal endometritis in 87.9%, fibrinous - in 12% of cases. At cows which have had persistent corpus luteum in 54.6% of cases was registered purulent-catarrhal endometritis, in 27.6% - fibrinous, in 17.8% - necrotizing metritis. At cows with ovarian cysts fibrinous endometritis was observed in 63.2% of cases, necrotizing metritis - in 36.7%. Thus, the more severe form of uterine inflammation was observed in cows, the more severe form of ovarian functional disorders observed in them. The authors found that any factors which negatively acting on the central nervous system or hormone levels, directly or indirectly, sharply reduce the reproductive function of animals

COMPARATIVE ASSESSMENT OF THE CLONE OF STOCK М9ЕМLA AVERAGEGROWING APPLE-TREE
DescriptionIn FSBRI «North-Caucasus zonal scientific-research institute of horticulture and viticulture» (Krasnodar) there was carried out the comparative economicbiological study of the average-height apple-tree stock М9ЕМLA in comparison with initial weakgrowing stock М9 in manifold, nursery and garden. Manifold bushes of the clone M9ЕMLA is quite worse in force than the stock М9 and were less branchy. Output of standard per hectare of manifold at the clone M9ЕMLA was on 35,5 thousand units more, and а standard condition of cuttings - on 13,2 % higher, than at the stock М9. Cuttings of the clone were less spiked and better rooted. In the first field of nursery, the plants of the clone had a vertical growth of the central conductor, slightly weaved and were more suitable to inoculation. The output of standard plants, in the variant with the use of clone M9ЕMLA by the variety Champion, in average for 2006-2010 was on 3112 units/hа, and on the variety Prikubanskoye – correspondently on 2470 units/hа higher than grafted on the stock М9. The cost price of 1000 seedlings on the clone M9ЕMLA was on 1962 rubles less than on the stock М9, and the standard of profitability of seedling growing, on the contrary was on 14-19 % higher. In the garden the trees on the clone M9ЕMLA were worse in growth of trees grafted on М9: on volume of the crone on 0,4-0,6 m3 , in diameter of the stem on 9-12 mm, in dependence on the variety, independently on the fact that some trees on clone were more weaker than grafted on the stock М9, their productivity for 2011-2015 was higher as from one tree as from the unit of area. The intensity of fruiting expressed in yield in kilos from a tree on the unit of volume of the top of a tree on the clone M9ЕMLA was on 33-39% higher than at the trees on the stock М9

Description
Only the rational, normally functioning legislation is able to afford free exchange of information, respectively and normal functioning of cultural institutions, and creation of effective social technologies and effective functioning of democratic society, as such. It only emphasizes its special social importance both for the country in general, and for each hotel citizen as cultural values cause internal stability of society, being its spiritual basis, its toposy. And the library science which is determined as - an industry of information, cultural, educational activities of society that includes education and development of libraries, forming and handling of library stocks, the organization of library, information and library and bibliographic servicing of users of libraries, preparation of library personnel, scientific and methodical ensuring development of libraries has special value in this aspect. The emphasized attention to a library science and people who work in organizations of libraries can be seen in the Presidential decree of Ukraine "About establishment of All-Ukrainian day of libraries" from 5/14/1998 No. 71/98 and which is directed as it is told in the Decree on increase of a role of the book in social and political and historical and cultural life of the population of Ukraine, and also on the problem resolution of development of a library science. Thus, it is possible to conclude that in Ukraine there are developments the legislation, both for needs of the most library science, and for implementation of free exchange of information within the country and beyond its limits. That, in turn, can be a basis as for creation, application and effective use of social technologies, and for further development of the cultural sphere of society

SIMULATION MODELING OF DISTRIBUTION OF EPIDEMICS ON THE BASIS OF AGENT APPROACH
01.00.00 Physical-mathematical sciences
DescriptionToday, infectious diseases remain a leading cause of premature deaths in the world. Agent-based modeling can play an important role in predicting the spread of disease and to assess the containment measures. The aim is to construct a multi-agent simulation model for the formation of epidemic measures to reduce effectively their incidence. Using the multi-agent simulation approach to modeling of epidemics due to the fact that the approach allows us to consider a number of factors influencing the epidemic process, makes it possible to carry out numerical experiments. The processes of the spatial distribution and temporal variation of these two groups of epidemics of infectious the author calls dynamics. Usually hard-implemented spatial components of the dynamics in the proposed model can be substituted by predfractal topology of the graph, which is built up by voluminous graphs - primers, and the dynamics of compounding prefractal graph, called its recognition, is responsible for the timing of the process component. Under the term of agent, we consider an elementary study participant. An agent is active; it is in a state that may change under the influence of factors. The properties of the agent are attributed characteristics that form the level of immunity: height, weight, gender, income, marital status, education, geography

DECISION SUPPORT SYSTEM FOR SELECTING THE METHOD OF PURCHASE OF SOFTWARE
DescriptionThe research is devoted to the problem of selecting the software acquisition method for the company. To solve this problem the decision support system which allows automating the process of selecting the software acquisition method was developed. The existing methods of software acquisition were reviewed in the article, as well as the analysis of possibility of their comparison was conducted. This analysis showed that the research should be limited to two alternatives - purchase of licensed program and using Software as a Service (SaaS). We substantiated the necessity of a mechanism that would allow the company to determine with a high degree of accuracy which software acquisition method was the most preferred. This mechanism was implemented in the framework of a decision support system consisting of three main blocks: database, model base and interface. The basis of the model base consisted of indicators calculated on the various methods for assessing the economic efficiency of information technologies. The above methods were ranked in descending order of their informativeness. Based on these results the algorithm of choice of software, the acquisition method was proposed. This algorithm formed the basis of the decision support system which block diagram is also presented in the article. It is expected that the developed decision support system will enhance the validity of the decisions made, reduce the complexity of the calculations, and minimize losses associated with acceptance of erroneous decisions
