VETERINARY AND SANITARY EVALUATION OF MUTTON AFTER USING BIOLOGICALLY ACTIVE FEED ADDITIVE “YODDAR”

Posted in 2019, Issue № 5(83) May 2019, VETERINARY SCIENCE | 0 comments

The results of studies of the effect of drug Yoddar on the meat quality of small cattle are given. It was revealed that when using the rams of the experimental group of drug Yoddar, meat meets the standards in all quality indicators, besides for some indicators it is better than meat in the control group. During the experiment, live weight and cost per 1 kg of live weight of animals of all groups are taken into account. Veterinary-sanitary examination was carried out on the slaughter site. Besides, the “technological instruction for waste processing at the enterprise of the meat industry” was fully observed. The microscopic and bacteriological indicators of the meat rams do not show that they have the best indicators that can be obtained from the experimental groups, which can explain the bactericidal properties of iodine, which enter into the body tissues. The obtained results suggest that the use of biologically active feed additive Yoddar on sheep farms of the Russian Federation is advisable because of its positive effect on metabolism, weight gain and the absence of negative impact on the safety and quality of meat.

RELATION TO LABOR AND EMPLOYMENT FORM OF X, Y, Z GENERATIONS: SIMILARITIES AND DIFFERENCES

Posted in 2019, 2019, ECONOMICS, Issue № 5(83) May 2019 | 0 comments

It has become increasingly difficult for people over 40 years old to find work in the national labor market in recent years. At the same time, we observe the following tendency: employers are not satisfied with employees, they do not like the attitude of the new generation to work, their work style, according to the results of studies conducted at the national level. Therefore, researchers faced with the task of ensuring the joint activities of the new and old generations, the things employers have to do in order to effectively manage employees, so it is necessary to study the characteristics of each generation, in particular, and determine their attitudes to work. It is required to determine both their similar and different sides based on research by Russian and Western scientists and institutions. The purpose of this article is to establish convergence and differences of X, Y, Z generations in four areas: social status and social conditions, values, psychological characteristics, a form of employment (work style) based on surveys of the Mongols among the above generations. Our research has shown that the time of birth and the values of people affect their attitude to work.

ON THE BEST APPROXIMATION BY ABSOLUTELY MONOTONIC FUNCTIONS ON SEMIAXIS

Posted in 2019, Issue №4(82) April 2019, PHYSICS AND MATHEMATICS | 0 comments

The main result of the paper (Theorem 2) is that in the space C(I) of continuous functions on the interval I = [0, ∞], the cone K⊂C (I) consisting of absolutely monotone functions is Chebyshev, that is, for each continuous function f∈C (I) there is a unique absolutely monotonic function φ∈K of the best uniform approximation on the interval I. In the proof, we use a special criterion for the uniqueness of the best approximation by the wedge (Theorem 1). This criterion can be used in proving the uniqueness of the best approximation for other cones consisting of continuous functions.

MATHEMATICAL COMPETITIVE MODELS ON THE TROPHIC RESOURCE

Posted in 2019, Issue №4(82) April 2019, PHYSICS AND MATHEMATICS | 0 comments

The authors have developed mathematical models of operational and interference competition on a linear range based on the systems of equations with distributed parameters. They also have conducted an analysis of stationary states stability. It is shown that the operational competition on the restored trophic resource does not lead to the disappearance of one of the populations due to competition. The model of interference competition contains various options for the effects of competition between the two populations. In both models, for populations with a small number of individuals, the influence of competition is not significant. The assessment of the distribution rates of small populations on the range is given, and the conditions for the existence of an autowave solution on an unbounded straight line are obtained. In order to construct a numerical solution of a boundary value problem for a system of nonlinear differential equations, they have used the grid method with software implementation in the programming environment of the Matlab environment. Numerical results are consistent with analytical results on fine grids.

COMPARATIVE ANALYSIS OF COMPUTATIONAL METHODS OF SYSTEM OF NONLINEAR EQUATIONS

Posted in 2019, Issue №4(82) April 2019, PHYSICS AND MATHEMATICS | 0 comments

The consideration of numerous applied problems leads to systems of nonlinear equations, they include boundary problems for ordinary differential equations and partial differential equations (solved by the finite difference method), optimization problems, problems of minimization of functions of many variables, the use of implicit methods for integrating ordinary differential equations, etc. Numerical solution of systems of nonlinear equations in the general case is a more complicated problem than the solution of systems of linear equations, since there are no methods that guarantee the success of solving any problem of this kind. Identifying the optimal method and its further selection allows you to increase the chances of successfully solving systems of nonlinear equations. In connection with the relevance of the above-mentioned, this article presents the algorithms for methods for the numerical solution of systems of nonlinear equations, according to which the root of a typical system for applied problems was searched. According to the obtained results, a comparative analysis was conducted in order to identify the optimal method. The optimal method is the one that found the values of all the roots of the system with the required accuracy in the least number of iterations.

TRASTUZUMAB-INDUCED CARDIOTOXICITY – INTERDISCIPLINARY PROBLEM OF MODERN MEDICINE

Posted in 2019, Issue №4(82) April 2019, MEDICINE | 0 comments

Trastuzumab is the basis of adjuvant therapy for HER2 positive breast cancer. This fact is confirmed by currently received remote (more than five years) results of clinical studies. Although trastuzumab is devoid of classical toxicity in the treatment of cancer, its symptomatic and asymptomatic effects on heart function are of great concern. This drug is characterized by the second type of cardiotoxicity (reversible cardiotoxicity). The meta-analysis devoted to the development of cardiotoxicity in patients with breast cancer, taking trastuzumab, showed that 3% of all patients experienced severe cardiotoxicity. In modern clinical practice, patients often have cardiovascular diseases, so it is impossible to go without a proper assessment of the risks of the upcoming treatment. According to the author’s opinion, the best solution to this problem is interdisciplinary interaction between cardiologists and oncologists.
