FREQUENCY CONVERTERS WITH IMPROVED PERFORMANCE
DescriptionIn the autonomous power supply systems there are widely used frequency converters that are able to simultaneously increase or decrease the frequency of the current and voltage stabilizing power supply. These positive properties of frequency converters can improve the operational and technical characteristics of the autonomous power supply system in the complex. The article suggests a functional diagram of a frequency converter performed on reversible rectifiers. We have presented timing diagrams illustrating the principle of its operation. The article also deals with two functional scheme of direct frequency converters executed on single-phase, threephase transformer with a rotating magnetic field. The principle of operation of these schemes has been also discussed in the timing diagrams. The proposed technical solutions for frequency converters contain a smaller amount of power electronic devices that make it possible, thereby reducing the level of electromagnetic interference, increase the efficiency and reliability of performance inverters. The considered scheme of frequency converters, can improve the technical characteristics of the autonomous power supply systems in the complex. We can significantly improve the performance of power systems through the use of modular aggregating principle of the basic functional units of an autonomous system

Description
It has been proved that theoretical scientific models created as a result of the learning process, reflect not the reality of "what it really is" and only the reality "what it is" in the process of interaction with tools of empirical knowledge, i.e. the organs of perception of a certain organism that supports a corresponding form of consciousness, experimental instruments and information-measuring systems of a certain functional level. Examples and consequences of the major mistakes that have been historically made by scientists for the substantial interpretation of theoretical scientific models: this error is unwarranted giving the model the ontological status ("hypostatizations") and its associated error model giving the status of universality. The history of the emergence and development of science was viewed as a process of sequential application of natural scientific method to the study of objects of knowledge, previously studied in the framework of philosophy. We have formulated a promising idea of solving problems of philosophy of natural science methods. In the framework of implementation of this idea, we have proposed a natural-scientific formulation and solution of the basic question of philosophy. This new scientific concept of "Relatively objective and Relatively subjective" and discusses the relationship of the content of these concepts from forms of consciousness. The article gives a natural-scientific definition of consciousness and offers periodic multi-criteria classification of forms of consciousness, including 49 forms of consciousness: the 7 types of 7 consciousness and cognition methods. It examines the dialectics of the changing ideological paradigms from antiquity to the present day and a place of scientific paradigms in the process. It also describes the law of denial-denial in the change of ideological paradigms and on the basis; it explores the hypothesis about the main features of the future ideological paradigm, formed in the present. We have formulated the correct principles of interpreting scientific models of natural-scientific method – scientific method of induction and the principles of open consciousness, i.e. the principles, opening the way for the formation of new, improved and more adequate models of reality than the existing ones which were considered the only true models

PROBLEMS OF RATING OF FINANCIAL ACTIVITY OF MANAGING SUBJECTS OF AGRARIAN SPHERE
DescriptionIn the article we have given a critical assessment of credit scoring by American economist D. Duran, we have grounded the developing of his method for the domestic economic conditions. The unacceptability of D. Duran’s method for the analysis of financial condition of domestic economic entities is explained by the following reasons: 1) the imperfection of the hierarchy of indicators of credit scoring, and 2) the imperfection of differentiation of scoring for the actual value of the indicators, forming the credit scoring by groups of firms. In the methodology of D. Duran the main indicator is a level of credit scoring profitability of total assets - for the first class of firms, that are the most financially stable, the authors have given a rating of "50 points" for the actual value of the profitability of 30%; the second most important indicator by the author’s choice is the ratio of current liquidity - for the actual value of the coefficient "of 2.0 and higher," are given 30 points to a first-class firms; the third indicator of the financial condition of firms author has defined as the ratio of the financial independence - for the first group of firms the actual value of the coefficient "of 0.7 and higher," are assessed 20 points. In the fifth, the last group of firms, numerical score is 0 (for the actual return on total assets "of less than 1%", as the value of the current liquidity ratio "of 1.0 or less," for the coefficient of financial independence "less than 0.2"). For assessment of the financial condition of the domestic agricultural producers, a priority in the hierarchy of indicators, in our opinion, has the ratio of financial independence, which is formed mainly by retained earnings. Our researches have shown that the numerical score of the coefficient value "of 0.8 and above" should be 50 points. The second most important in the assessment of the financial condition of the organization, in our opinion, is the profitability of total assets; its actual value "of 5% and above" should correspond to score 30 points. The third in the system of indicators, characterizing the financial condition, is the ratio of current liquidity of the assets. Its actual value "of 3.2 and above" should be evaluated in 20 points for the agricultural organizations of the first, most financially stable, group

DEVELOPMENT OF A FUNCTIONAL FEED ADDITIVE
DescriptionThe new feed additives for animals based on milk whey, enriched with sprouting wheat, barley, maize grains and lactic-acid bacterium have been presented in this article. This study explores the possibility of combining the prebiotics ability of milk whey and sprouting grains with feed probiotic attributes of microbe to enhance gut health of animals and digestibility of the feed. Twelve variants of products were tested in the study using the microbial and physical-chemical approaches. All the assays showed high count of microorganism and high content of reducing sugar. The results of investigation indicate that selected feed additive show high quality. An additional point is that it contains useful organic acids (lactic, acetic and propionic acids) and 2,1×109 colony-forming unit of probiotics microorganism that hold the concentration for 4 months. There are not yeast, must, coliform bacteria and Staphylococcus aureus in the developed functional feed product. It contributes to the normalization of the microflora of the gastrointestinal tract of animal, suppression of conditionally pathogenic and putrefactive microflora. The elaborated feed component will help to provide combined feed companies with accessible high-quality raw material

IMPLEMENTATION OF POTENTIAL PRODUCTIVITY OF THE OLD VARIETIES OF WINTER WHEAT
06.00.00 Agricultural sciences
DescriptionIn the article, we discuss issues of morphological and physiological control over plants of winter wheat. As the object of the research, we have selected landraces - the population of winter wheat, which was grown on the territory of the Kuban region in the last century. The aim of this work was determination of the effect on the reproductive system of winter wheat varieties of factors such as conditions of cultivation and processing "Cecece 750" 1.5 l/ha D. V. crop retardant. To achieve this goal we have conducted a morphological analysis of the growth cone at the VI stage of organogenesis, which provide quantitative evaluation of potential future seed production of spike of winter wheat. To study the effect of the year of breeding on the reproductive system of winter wheat varieties the analysis of variance was calculated according to the scheme 3×7 factorial variability characteristic due to the influence of genotype (factor B), cultivation year (factor A), that is repeated in time is interpreted as the effect of the year conditions of cultivation. The influence of retardant on the reproductive system of winter wheat varieties was conducted using the analysis of variance on the above described scheme, 2×7, where the factor "A" is presented in two gradations (options, retardant treated and not treated), in this case, repeated for years was excluded as a factor. The result of researches indicates that the rate of realized productivity is variety-specific and can serve as a measure of the flexibility of the studied cultivars to different environmental conditions. The analysis of variance showed significant retardant effect on the realization of potential productivity in all variants of the crops of soft winter wheat. The comparison of the average general population indicates that the genetic potential of tall varieties may not manifest even in favorable for crop cultivation. The artificial reduction of plant height by inhibiting the growth of retardant is an effective way to identify high productivity of these genotypes as varieties of winter and Nemenchinskaya Old No. 346

REALISM AND THE ANTHROPOLOGICAL PRINCIPLE IN RUSSIAN PHILOSOPHY
DescriptionThe anthropologism is traditionally considered the main feature of Russian philosophy. The article reviews some anthropological ideas that have received natural development in such direction of thought as philosophical realism in the 2nd part of XIX century. Philosophical realism is positioned as a trend that has emerged within the mainstream of the basic traditions of Russian philosophy. It is noted that this direction is defined as an independent, in the wake of the strengthening of Russian science as a new cognitive paradigm. Substantively, philosophical realism is presented with the theories and concepts of the natural sciences developed in the 2nd part of XIX century. The realistic outlook, ripening in the Science environment, not only supported the anthropological tradition of Russian thought but put them on a scientific basis. It was dominated by the view that only by using scientific methods can reveal the objective laws of coexistence between man, nature and society. The article deals with the anthropological theories of Russian thinkers such as A.N. Radishchev, A.I. Galich, N.G. Chernyshevsky. The anaysis shows that realistic outlook in the natural sciences in the area of human theory relies on the principles of integrity, panmoralizm, cosmism. The conclusion is that the philosophical concepts by realistic scientists are out of attention of modern scholars. In the meantime, the study of these theories can make a significant contribution to the practical experience of comprehension of reality, as well as help to discover new sides of the domestic, national philosophy

RESOURCE-SAVING APPROACHES TO THE POULTRY FEEDING
06.00.00 Agricultural sciences
DescriptionThe experiment studied the use of an herbal component in feeding of young geese, consisting of hay meal and alfalfa juices coagulate. The replacement of 50 % of complete feed by the studied feeding stuff reduced the protein content in the diet by 9.9-14.9 % and increased the content of crude fiber 1.76-2.01 times. Gross weight gain in the experimental group decreased by 3.9 %, with an increase in feed cost by 17.1 %. However, carcasses of geese in experimental group increased absolute weight of muscles of the breast and legs by 28.6%, and the relative – 5.6 % (Р˃0.05). Using of herbal ingredients tended to increase the yield of dressed carcass by 4.8 %, while the share of internal fat and skin with subcutaneous fat was decreased. There were no differences in the chemical composition of poultry muscle tissue in the groups. Using of herbal ingredients decreased the cost of 1 kg of feed by 0.7 rubles, but the cost price of weight gain increased by 5.0 %. It was concluded that it is necessary to carry out additional studies involving the feeding of poultry with the identical by nutritional value compound feed with the additive under study or without it

06.00.00 Agricultural sciences
DescriptionThe article deals with a combination of different methods of cultivation of winter barley on the background of plowing, and their impact on growth, development and crop yield. The main technological factors allowing implementing the biological potential of culture are adaptive variety, quality seeds, predecessors, sowing and harvesting, fertilizer, soil fertility, crop care, including protection from weeds, pests and diseases. Barley is the culture of versatile use, which is grown for food and feed purposes. Intensification of cultivation methods of this phenomenon is essential and significantly affects the grain yield of this crop. Under the natural fertility of the soil and favorable weather conditions for black earth of Kuban it is possible to get 3,0-3,5 tons per hectare of winter crops of grain, and this requires the creation of an optimal diet, because one of the main factors affecting the productivity of field crops, including one phenomenon are fertilizers. In addition, the level of soil fertility and protection system of weeds, pests and diseases has great importance. Since these types of issues are relevant for agriculture, we have carried out studies to identify the optimal combination of different methods on growth, development and productivity of a single phenomenon
