DescriptionThe concept of generic polynomial appeared in Saltman’s works at the end of the last century and it is connected with the inverse problem of Galois theory, which is still far from its complete solution. Let G be a finite group and K be a field, the polynomial f(x,t1, … , tn) with coefficients from the field K is generic for the group G, if Galois group of this polynomial over the field K(t1, … , tn) is isomorphic G and if for any Galois extension L/K with Galois group isomorphic G there are such values of parameters ti = ai , i = 1,2, … , n, that the field L is the splitting field of the polynomial f(x,a1, … , an) over K. Generic polynomials over a given field K and a given finite group G do not always exist, and if they exist then it’s not easy to construct them. For example, for a cyclic group of the eight order C8 there is no generic polynomial over the field of rational numbers Q, although there are found specific polynomials with rational coefficients having Galois group isomorphic C8. Therefore, this is of interest to construct generic polynomials for the group G in cases when G is a direct product of groups of lower orders. In this study we show to solve this problem in case when G is a direct product of certain cyclic groups and there is a type of corresponding generic polynomials. Moreover, we give constructions over the fields of characteristic 0 and over the fields of characteristic 2

Description
Results of the research on ecological safety of utilizing high clearance tractors for cultivation and harvesting of high stalk plants are presented. Purpose of the research was to decrease damaging of high stalk plants during multi-pass harvesting by tractor parts. For increasing efficiency and competitiveness of high stalk plants decreasing prime cost of production, increasing profitability and labor productivity are required. This can be achieved by introducing complex factors, which together with other factors as complex technological and technical modernization are required. Basic direction of modernization is utilizing completely new technologies and renewal of machines. Modern tractors utilized for tobacco growing have been analyzed. Basic demands for high clearance tractor which can be used for tobacco, grape and fruit trees growing have been developed. Researches on studying the tobacco plant folding during harvesting have been carried. Scheme of high clearance tractor MTZ-80 which can be assembled with machines for multi-pass harvesting of high stalk plants without their damaging has been developed. New scheme for modernization tractor MTZ-80 into high clearance model has been proposed. It can be done by changing speed reducers and forward wheels with size 11,2x20 on size 11,2x28. This will increase clearance from 470 to 840 mm

10.00.00 Philological sciences
DescriptionThe article is devoted to the analysis of the features of the translation of onomatopoeic sounds when translating a literary tale on the material of the fairy tales of K.S. Lewis "The Chronicles of Narnia." The work compares the English literary fairy tale and its translation into Russian in order to reveal the laws of the translation of onomatopoeias in the literary text. The article points out that in children's literature a special role is assigned to onomatopoeia when creating an indirect characterization of the character, describing its emotional state, a certain atmosphere. Four lexical groups of onomatopoeias are thought to be widely represented in the fairy tales "The Chronicles of Narnia" written by K.S. Lewis: imitations of sounds produced by human beings; imitations of sounds produced by animals and birds sounds; imitations of sounds of natural phenomena; imitations of sounds of inanimate objects. Translation of onomatopoeias into the text of fairy tales can represent a certain problem for translators. The article substantiates the specificity of the equivalents selection of the English-speaking onomatopoeic vocabulary in Russian language. It emphasizes the special significance of the transfer of author's onomatops, which can be translated either by transcription or by variant correspondence. The conclusion is drawn that in most cases the translator seeks to select a standard onomatop as a translation equivalent, which will naturally enter the narrative fabric

Description
The use of intensive milk production technologies in practice, nonobservance of the principles of feeding and keeping animals leads to a decrease in the level of compensatory-regenerative processes in the body, violation of general and specific metabolic reactions, emergence of a number of pathological conditions, and, primarily, hepatopathies leading to a decrease in the productivity of dairy cattle, to the birth of unviable young animals and to the impossibility of their further exploitation. Therefore, on the background of early diagnosis of violations of the liver it is necessary to conduct adequate pharmacoprophylaxis, which prevents further development of hepatopathies with the help of hepatoprotectors. These preparations include a new injectable one – livazen, the mechanism of action of which works due to its antioxidant and membrane-stabilizing action. The preparation has a lipotropic effect, favorably affects the antitoxic and pigmentary function of liver, and increases resistance to hypoxia and various kinds of intoxication. Research conducted to study its effect in the system of prophylactic measures of hepatosis in sterile cows showed that on the background of the use of lavazen there was a significant increase in total protein by 16,6% and increase in albumins - by 13,8%. The level of γ-globulins, on the contrary, decreased by 20,9%. The study of the preparation had a normalizing effect on lipid metabolism, which was manifested by an increase in the concentration of triglycerides in 3,1 times and increase in cholesterol by 24,7%. An increase in the concentration of calcium by 14,5% was also found out. The use of livazen allowed to ensure a tendency towards a decrease in enzyme activity (according to AST - by 6,9%, by ALT - by 24,4%, according to alkaline phosphatase - by 11,6%), in contrast to control animals whose aspartate aminotransferase increased by 11,3% from the initial; ultrasonography of liver of cows confirmed the expressed effectiveness of the pharmacoprophylaxis

PERSONALITY TRAITS OF WOMEN RAISING CHILDREN IN SINGLE PARENT FAMILIES
19.00.00 Psychological sciences
DescriptionThe present study explores personality traits of modern women raising children in two-parent and single-parent families, and specific aspects of their interaction with the children. The comparative analysis of family values, gender-related particularities and the level of subjective control of the mothers’ personality have been given. The differences in personal characteristics of mothers in the two groups of women under study have been determined. Mothers raising children in single-parent families are characterized by such family values as social activity, attractive appearance and the upbringing of children, whereas mothers in twoparent families turned out to rank the values of children upbringing and psychotherapeutic character of communication as most important. As compared to women in two-parent families, women in singleparent families demonstrate more often masculine and less feminine qualities. The specific aspects of interaction with children have been defined in relation to mothers in the groups under study. The interrelationship between the personal qualities of mothers and the nature of their interaction with children has been analyzed. Positive and negative aspects of the impact of personal qualities of the mothers on the stylistic peculiarities of their interaction with children

RURAL (AGRARIAN) TOURISM: RETROSPECTIVE ANALYSIS AND MODERN DEVELOPMENT IN THE KRASNODAR REGION
DescriptionMany scientists suppose that rural tourism as a kind of tourism industry in Russia has not got long history. But we can see its manifestations at different stages of tourism development, which are described in the given article. In different historical periods, rural tourism had its own forms, modifications and kinds of activity. That is why we can say that agrarian tourism took place in pre-Soviet and Soviet periods too. Besides, we still have troubles with theoretic aspects of rural tourism. Today science society invents a determination of rural (agrarian) tourism, creates classifications of this and so forth. Nowadays rural tourism is a polyfunctional phenomenon. That is why we should explore it in more details. The Krasnodar region has a lot of recourses which allows us to develop many kinds of tourism, including agrarian on its territory. Existing legal environment creates attractive investment climate and helps to develop rural tourism in the Krasnodar region successfully

THE REALIZATION OF GALOIS GROUPS BY TRINOMIALS OVER THE FIELD OF RATIONAL NUMBERS Q
01.00.00 Physical-mathematical sciences
DescriptionIt is known that not every finite group can be realized over the field of rational numbers as a Galois group of some binomial. In this connection, a more general question arises: suppose that there is given a finite transitive subgroup G of the symmetric group S on n symbols; Can this group G be realized as a Galois group of some trinomial of degree n over the field of rational numbers? In this paper we prove that every transitive subgroup of the group S can be realized in the form of the Galois group of a certain trinomial of the degree n, for the values n = 2, 3, 4. For n = 5 , 6 we give examples that realize concrete Galois groups. In the case n = 7, all the transitive subgroups of the group S are realized, except possibly one group of the isomorphic dihedral group D. Further calculations will be directed to the realization of specific Galois groups for n = 8, 9 ..., however, the number of transitive subgroups of the group S for n = 8, 9 ... grows very fast, so the larger the value of n, the more difficult it is to realize not just everything but the specific subgroup of the group S in the form of a trinomial over Q
