06.00.00 Agricultural sciences
DescriptionThe researches were carried out with the support of the Federal state budget establishment "The development assistance fund of small forms enterprises in scientific-technical sphere" (Fund for the innovation promotion), contract number 0019671. The fodder additive «Nutovit» in growing chickens feeding application enriched mixed fodder for farm poultry with protein and especially with the amino acid such as lysine. Scientific-economic experiment was carried out at the poultry-farm enterprise of the Volgograd region in 2015-2016. 4 growing chicken groups with 54 heads in each group were selected for the experiment. The growing chickens were selected according to the cross, age, living body weight, health status. The difference in experimental poultries feeding was that in the experimental groups the sunflower oil cake in the feed mixture was replaced by fodder additive "Nutovit". It was established, that the essential amino acids availability and the saturation of fodder additives with vitamins influence positively on: young chickens live weight and average daily growth, the live weight to 120-days age in the second experimental group amounted to 1657 g, and average daily growth was to 12.46 g, which is higher compared to the control group by 4.48 % at 100% poultry livability; blood morphological and biochemical composition: formed elements of blood, namely erythrocytes, in the experimental groups young chickens blood were more in 0.02 to 0.05×1012/l compared with the control one. The researches established that blood leukocytes reduction in growing chickens of the experimental group was little, in 0.04, 0.09, 0.08 ×109 l. Calcium content in growing chickens blood in the control group was 2.6 mmol/L. The experimental group surpassed the control on 0.14-0.21 mmol/L. The phosphorus content in chickens blood in the experimental groups exceeded the control one by 0.08-0.24 mmol/l. In addition, the feeding cost reduction was established due to the fodder additive "Nutovit" use

Description
It is estimated that (85-95%) of the electric motor failures occur due to damage to the stator winding. In this case, more than 90% of damage are because of interturn short circuits. Short circuits in stator windings of stand-alone asynchronous generator change the base magnetic flux incidentally, so the probability of its long work with such kind of damage is great. A latent failure, existing as a loop closure, significantly reduces the reliability of the generator as a backup power source. Now sensitive protections of asynchronous generators do not exist, since it is believed that in the case of short circuits (short circuit), the generator loses its excitation, and protection is not required for it. Identification of information signs of short-circuit currents in the stator winding of an asynchronous generator makes it possible to develop relay protection. The main principle of detection of stokes closures in the stator winding of an asynchronous electric motor is the measurement of the emerging asymmetry of the stator currents. It has been established that in the case of short-circuit faults, the asymmetry of the currents and voltages is not large and comparable to the asymmetry in the AAG load circuit. This does not allow performing a protection that reacts to this asymmetry. You can also say about changing the harmonic spectrum of currents and voltages. To build protection, it is necessary to use highly sensitive circuits for detecting the asymmetry of a three-phase system of currents and voltages, as well as distortion of the shape of currents and voltages, for example, by harmonic analysis. Do not exclude the possibility of using other protection devices, such as reacting the vibration of the case of an induction generator in the event of damage to the stator winding

TOOLS FOR OPTIMIZING PRODUCTION MANAGEMENT TAKING INTO ACCOUNT PRICING MODELS
DescriptionThe state of any economic system depends on the values of its parameters, both in the current period and at previous times. Therefore, in the process of optimization of production management, it is necessary to take into account this feature of the development of the systems under consideration. The most important task of economic research is the establishment of an equilibrium price. The most suitable hysteresis converters for solving this problem, the formal description of which is based on their operator interpretation. However, at present, when analyzing the functions of supply and demand, a cobweb-like model and its analogues are used, as a rule. This article discusses the unresolved problem of optimizing production under conditions of hysteresis pricing and competition. Taking into account that their mathematical modeling is the main method of analyzing economic systems with hysteresis properties, different pricing models (discrete and continuous) are considered in the article, as well as economic and mathematical tools for optimizing production activity under hysteresis pricing conditions. The developed models can be used to increase the adequacy of the formal mathematical description of the corresponding systems, which is the basis for more accurate forecasts of their development. In the conditions of hysteresis pricing, production optimization algorithms will allow to create optimal (in terms of achieving maximum profit) price and production strategies for the development of economic systems

Description
The study discusses the activities of TNCs as a factor of development of regional innovation systems of economy, which contributes to the spread of new methods of management, marketing, and new technologies. The prospects for Russia's development can be viewed as a huge resource for business expanding of the largest international companies, which gives relevance to the issues of studying TNCs as a global subject of the world economy, as well as the adaptation of international companies to Russian conditions. According to this the study of trends of transnationalization on the example of the Russian agricultural machinery market and the search of the ways to improve the efficiency of its functioning is an important factor in the development strategy of the state. Factors affecting the attraction of foreign investors to Russia include cost and production factors (availability of natural resources, cheap labor, the possibility of R & D and innovation); the attractiveness of the market (the size of the market and income per capita, the dynamics of growth in domestic and neighboring markets); government initiative (economic and political stability, tax incentives, developed infrastructure). The analysis in the article suggests that the presence of TNCs in the region is a significant factor in increasing innovation activity. In addition, the development of balanced investment programs, taking into account the plans of TNCs, as well as the obligation to monitor their implementation, is the key to increasing the investment attractiveness of the regions

Description
The article reveals the thought of hermeneuticity of philosophy by its nature and methods of exposition. Philosophy is not technical, but personal. The study of personal philosophy is impossible without studying the life journey of the philosopher, considering the constitution of his soul and mind. Philosophy always contains a hidden sense that needs to be deployed. It proves the necessity of transition in teaching philosophy to the position of hermeneutics. Insight of philosophy should be sought in education. Only in a condition of insight does man find the direction of his life, reach the fullness of his being. The skill of philosophizing is available only to those who can talk with questions. Sense is born in a "live" dialogue. Asking about the known for the purpose of discovering the unknown sides of the object is the difference between philosophical thinking. Philosophical problematic is diverse and contradictory, and therefore, the existential purpose of philosophy, in the opinion of the authors, is self-interrogation. And philosophical questions do not always require an answer. Philosophical questions do not disappear anywhere; questions are more important than answers. Questions serve as symbols of constant movement and changeability. Uniformity and sameness is not inherent in philosophy. Philosophy is personal, original and impulsive, does not allow invariant judgments. Philosophy should be studied only using a philosophical method

SECONDARY IMMUNODEFICIENCIES OF SMALL PETS AND THEIR CORRECTION USING MURAMYLDIPEPTIDE
DescriptionThe revolutionary discoveries of recent years in immunology has proved that protection from infections and biological aggression leading role played by innate immunity, which leads to the launch and subsequent work of specific adaptive immunity. Today, it is well-known that almost any pathology of the animal affects the immune system and creates an immune imbalance, leading to development of chronic pathological process, frequent relapses and to the development of different kind of complications. Secondary immunodeficiency states are widely distributed and differ in many etiological factors age, nutritional, medicinal, infectious and neoplastic nature, which leads to increased susceptibility of animal to various раthogenic factors, the weakening of the body. Awareness of the role of immunological disorders in the pathogenesis of a number of diseases has led to the need use in veterinary medicines that are aimed to influence on the immune system of the animal at the known molecular mechanism, to combine safety with high clinical efficacy. In this respect, a promising immunomodulators of microbial origin, due to the knowledge of the recognition mechanisms of the innate immune system such as bacteria as a whole, separate structural units, including mini-optimal biologically active fragments. This review is dedicated to one of the immunomodulator of microbial origin – which is an analog of biologically active fragment of muramyldipeptide of bacterial cell walls ‒ glucosaminylmuramildipeptide (GMDP), which is the active substance of registrated in Russia drug with the trade name Glicopin for use in veterinary practice. The drug showed high efficiency when used in cats, dogs, rodents, ferrets with infections of bacterial and viral etiology; cancer; with the aim of improving the natural resistance of the organism of young and old animals; enhance the effectiveness of vaccination in immunocompromised animals; postvaccine reduce complications; reduce stress financial position, such as during transportation and various veterinary treatments; injuries and on-line intervention (for stimulation of repair processes and tissue regeneration); prevention of immunodeficiency in newborn animals; the reduction of postpartum involutional processes in the uterus. Analysis of literature data allows us to consider an important outcome of immunologiс discoveries of recent years is the change of views on the question of the treatment of infectious diseases and the role of drugs as activators of innate immunity, among which an important role is played by a synthetic analogue of muramyldipeptide (GMDP) is a drug with a known molecular mechanism of action

OPPORTUNITIES OF REGIONAL AGRICULTURE IN IMPORT SUBSTITUTION
DescriptionThe problems of import substitution, resource features of the agrarian economy, through which you can generate significant competitive advantage, are discussed. It is noted that low abroad interest rates on loans create obvious unequal starting opportunities throughout the domestic business. As a result the cost of imported food in value chain terms reached in our country an enormous rate of $45 billion and that government realized the need of strengthening of food security, transferring of production of traditional kinds of products which form the basis of consumption of the population in our country, to the domestic market. It is noted that we need temporary moderate state protectionism and protection of the domestic market with the aim of modernizing the economy, attracting investors in the important field of production with high risks. The main problems and solutions that will help to further successful implementation of this strategy in the sectors of our economy are highlighted. It is noted that our region has the most effecting rural industrial structure, the best country’s climate, enlarged crop rotation, cheap labor resources, extensive experience in agribusiness. It is proposed to perform a set of measures to reduce systemic risks in agribusiness
