ABOUT THE MOTION OF THE VIBROLIQUEFIED SEPARATED LAYER OF GRAIN ON THE FLAT SIEVE OF FINITE WIDTH
Description
The aim of the research is analytical determination of the middle speed of the corn seeds on the flat vibrating sieve of finite width. The object of the study is the process of sorting of seeds of corn on the flat vibrating sieve. The mathematical modeling of the motion of the separated layer of the cereal mixture on the sieve is conditioned by the necessity of intensification of division of grain-growing materials on a flat sieve. Despite the significant progress in the development of mathematical models of the motion of a mixture on vibrated sieve, their further refinement remains an actual task. In particular, in calculation practice, theory in which the width of the flat sieve is considered infinite is used, i.e. the impact on the process of the moving frame of the sieve bed is not taken into account. In connection with absence of estimations of the error brought in by this assumption, the necessity to develop a theory of the movement of the mixture on a sieve of the finite width appeared. For the analysis, the following assumptions were accepted: first, the corn seeds were considered as balls of different diameter, second – the layer of grain on a sieve was considered as heterogeneous viscid liquid. Based on undertaken study it is set that most rational for the achievement of the put aim is application of method of Bubnov-Galerkin. As a result of undertaken research analytical dependences are received for the calculation of flowrate of grain mixture on the vibrational sieve of the final width taking into account separation of the mixture into factions

TECHNIQUE OF CHOOSING COMPETITIVE STABLE BEHAVIOUR STRATEGY FOR AN ECONOMIC ENTITIES
Description
The article gives the analysis of the questions that provide economic entities stable functioning in extreme competitive interactions. The task of choosing competitive stable behaviour strategy of the economic entity on the basis of efficient use of a resource is defined in maximine terms. To solve the problem it is suggested to use the means of a multistage nonzero attrition game and a negative-sum “gain”. The ways to overcome major difficulties of a numerical solution of the formulated extreme problem in connection with its dimension and the kind of an optimizable function that might be discontinuous, nondifferentiable and multiextremal are found out. Due to its discrete behaviour a criterial function is given in terms of Taylor approximation. Derivatives in the direction are calculated to find the pair of mixed strategies that is the solution of the considered game. On the basis of the suggested optimal solving algorithm by means of successive approximation maximine value of the efficiency criterion of the economic entity functioning and optimal distributions of the strategies application probabilities that provide its stable (balanced) “survival” are evaluated. The application of competitive stable behaviour strategies based on maximum efficient use of resources allows economic entities to remain viable and provides balanced competitive environment in regional sectors of economy

Description
Occupation of the Soviet territory by German fascist invaders during the Great Patriotic War caused considerable damage. The Soviet Government developed legal and regulatory framework for the methods of assessment of damage. The purpose of this article is to analyze the legal framework, by the example of a regulatory act according to which calculation of damage to the collective farms in the occupied territories during World War II was made. The NKVD instruction "On the procedure of collecting, recording and storage of documentary materials relating to the atrocities, destruction, looting and violence of the German authorities in the occupied Soviet areas" was adopted in May 1942. Based on the instruction, and under orders of the NKVD in Elista, events to identify and collect materials that characterize the crimes of Hitler's government were carried out. According to these instructions, materials reflecting Nazi atrocities were subjected to the mandatory deposit of the State Archives. The paper gives summary quantitative data on the results of assessment of damage caused during the occupation period in August 8, 1942 to January 20, 1943

TO THE ISSUE OF PRINCIPLES OF TAX AUDIT CLASSIFICATION
Description
The article deals with the research of methodological principles of tax audit development. In particular there is analyzed one of the most important methodological issues - the selection and classification of the basic principles of tax audit. The basic methodological approaches to the classification of principles of various economic phenomena including audit allocated to various domestic researchers are analyzed. The possibility of development of tax audit methodology on the basis of the audit and management methodology is explained. By the analysis results the classification criteria of the principles of tax audit are highlighted. Relying on the provisions of international audit standards, Code of ethics for professional accountants, Independence rules of auditors and audit organizations, scientific economic literature addressed the issues of selection and justification of principles of auditing and principles of tax audit, taking into account the selected criteria the author offers a classification of principles of tax audit. A brief description of each selected group is given. The proposed approach to classification of principles of tax audit deepens the methodological framework of the study area and thus its use contributes to the quality of inspections undertaken. In the research process the author used the General scientific methods and various special teaching methods aimed at the discovery and scientific justification of key issues raised in this article: methods of analysis and synthesis, induction and deduction, comparison and generalization, grouping and systematization, classification

06.00.00 Agricultural sciences
Description
The article analyzes the possibility of complex processing of one of the most important secondary raw materials of Krasnodar region – sugar beet pulp with the aim of obtaining a food product and enriched feed additives. Meanwhile, the use of environmentally safety technologies that cause minimal harm to the environment and human health is provided. One of the most valuable components of sugar beet pulp after extraction of sugar is pectin substance. Sugar beet pectin substances have high complexing ability and are used not only in food industry, but also in medicine. They are natural detoxifiers and antioxidants. Currently, only dry powder pectin is produced from sugar beet pulp and only by foreign producers. Making food pectin extracts from sugar beet pulp will not only reduce the number of processing steps, but also significantly reduce the cost of the final product. Food pectin extracts can be used not only as a standalone product in treatment and prophylactic nutrition, but also as an ingredient in the manufacture of soft drinks, confectionery and bakery, meat and dairy products, etc. The technology of producing a valuable component of feed bioproduct based on spent sugar beet pulp and a microscopic fungus of the genus Trichoderma is described

Description
The research purpose was estimate of the red oak growing suitability in Mari El Republic. To achieve this goal we investigated experienced 44-year-old red oak plantation at the Botanical garden-Institute, determined acorns morphological characteristics of red and English oaks and seedlings grown from them. The evaluation of red oak plantings identified excess of average height and tree diameter in comparison with English oak, but the sanitary condition of both oaks forests was weakened due to the influence of the complex of unfavorable factors. Morphological acorns evaluation showed that the shape factor of acorns of English oak is equal to 1.64, while the red oak is 1.1. Biometrics parameters of red oak bareroote seedlings in the field were higher than English oak bareroote seedlings. In greenhouse biometric parameters of red oak container seedlings had not excess. According to this research, red oak is recommended for use in landscape construction in Mari El Republic

Description
The gaining of maximum amount of daily young animals in a greater extent depends on disinfection of incubation eggs which in complex of veterinarysanitary arrangements held in poultry factories on prevention and elimination of poultry infectious diseases takes an important part. The perspective of ozone application in industrial poultry breeding is conditioned with its advantages which it characterizes in comparison with other chemical substances. It was settled that ozone has a special ability to detain the growth of fungi on biological substrates, also the process of mould appearance on the surface of eggs’ shell even at 90% of relative moisture. At substantiation of parameters and regimes of electro-technological process of egg storehouse ozonation there were implemented the experimental researches. The general bacterial semination of eggs’ shell decreased on 94,1% after disinfection of incubaion eggs with ozone. The relative faults of experimental values from theoretical ones are 7%. In the result of production trials there were set the parameters of quality of the worked out electrotechnological process of egg poultry factory storehouse ozonation: time of regulation ‒ 8 minutes, dynamic fault ‒ 0,9, coefficient of overcorrection ‒ 4,5%, generalized integral mean-square index ‒ 10,6%. Obtained data testify against the qualitative regulation of allocation of concentration of ozone in a egg storehouse

Description
The analysis and assessment of risk at the macrolevel in this context is understood as assessment of extent of influence of the external environment (macro environment) on activity of the integrated production system. In the article the model and the technique of calculation of an integrated indicator of risk of an adverse effect of the external environment of the agro-industrial integrated production system is offered. All stages of creation of the model which include representation of basic risk factors of macrolevel in the form of linguistic variables are described, each of basic risk factors is a compound linguistic variable. For obtaining total value of a basic factor the matrix scheme of aggregation of compound factors to basic level is used. The equation of model of an integrated indicator of risk of an adverse effect of the external environment on the integrated production system is presented. The principle of recognition and interpretation of result on the basis of standard fuzzy 01-classificators is shown. Also in this article the interrelation of an integrated indicator with the choice of the strategy of development for business system by definition of a condition of the external environment is shown, and depending on it the strategic scenario of development of business system is offered

Description
We consider an approach to the transition from continuous to discrete scale which was defined by means of step of quantization (i.e. interval of grouping). Applied purpose is selecting the number of gradations in sociological questionnaires. In accordance with the methodology of the general stability theory, we offer to choose a step so that the errors, generated by the quantization, were of the same order as the errors inherent in the answers of respondents. At a finite length of interval of the measured value change of the scale this step of quantization uniquely determines the number of gradations. It turns out that for many issues gated it is enough to point 3 - 6 answers gradations (hints). On the basis of the probabilistic model we have proved three theorems of quantization. They are allowed to develop recommendations on the choice of the number of gradations in sociological questionnaires. The idea of "quantization" has applications not only in sociology. We have noted, that it can be used not only to select the number of gradations. So, there are two very interesting applications of the idea of "quantization" in inventory management theory - in the two-level model and in the classical Wilson model taking into account deviations from it (shows that "quantization" can use as a way to improve stability). For the two-level inventory management model we proved three theorems. We have abandoned the assumption of Poisson demand, which is rarely carried out in practice, and we give generally fairly simple formulas for finding the optimal values of the control parameters, simultaneously correcting the mistakes of predecessors. Once again we see the interpenetration of statistical methods that have arisen to analyze data from a variety of subject areas, in this case, from sociology and logistics. We have another proof that the statistical methods - single scientificpractical area that is inappropriate to share by areas of applications
