A method of solving symmetric polynomials of two variables is presented in the article. Several of such problems have been solved. There are very hard problems among them which were included in Mathematical Olympiads.

This article deals with the deposit policy banks. Determined that the savings accounts are the most diverse and the basis for their classification is the criteria of the sources of contributions, their intended use, the degree of profitability. The focus is on the definition of criteria, goals and objectives. This article can be viewed as the formulation stage for further research in the master's thesis.

In this article the question connected with the activation of cognitive activity of students. It one of issues of the day on the modern stage of development of pedagogical theory and practice. An author exposes development of activity, independence, initiativeness, creative approach to the thing, these are the requirements of life, qualificatory that direction in that it is necessary to perfect an educational process in a great deal. Searches of ways of development of schoolchildren’s activation of cognitive activity, developing their cognitive flairs and independence is a task that teachers are called to decide. The use of ICТ, that allows to activate thinking, ability to offer the variants of vision of problem, question, themes in the narrow and wide understanding and participating in the discussion are examined in the article. It helps to improve quality education, forms a culture, aesthetic skills of students, develop attention, memory. All this has a practical orientation in different areas and spheres of activity of student. Information technologies, examined in this scientific article as a process of the use of totality of facilities, methods of collection, treatment and communication of data - assists working off at the methods of students of actions, helps forming of processes of self-government of personality, will transform an effectively-practical sphere and carries out the emotionally-semantic going near the study of questions, that discussions, professional orientation.

In this article, the migration processes and their influence on socio-economic development of the Pavlodar region are considered. The concept of migrations, factors and types of migration are highlighted.. The demographic cases in the region are studied for research of migration processes and their influence on socialand- economic development of the Pavlodar region. Impact of migration on social-and-economic development of the country can be both positive and negative. The account of these factors is important for adjusting of migration processes and optimal policymaking in this sphere.

This article defines tolerance. The role of parents in the formation of tolerant relations between children and parents has been revealed. Tolerant education of children should become a necessary need of our society. In this paper we give the definition of tolerance.

The production of vaccine preparations before release requires standardization of their immunobiological parameters, especially safety and immunogenic efficacy. An indicator of the immunogenic effectiveness of the lumpy skin disease vaccine is the resistance of vaccinated cattle against the virulent virus. However, according to preliminary studies, the virulent control virus did not always cause clinical disease with characteristic symptoms when infected subcutaneously. The purpose is to develop a biological model in the form of a complex consisting of a pathogenic virus, a method of infection and a susceptible animal to assess the immunogenicity of a lumpy skin disease vaccine. Local cattle, intact from lumpy dermatitis, were used to reproduce lumpy dermatitis and develop the causative agent of the disease. As the initial infectious virus, we used a 20 % tissue suspension of nodules (skin nodules) obtained from cattle that fell ill with lumpy dermatitis in the field in the Atyrau region in 2016. As a viral mass to control immunogenicity, a 20 % suspension of skin nodules and edematous skin tissue at the site of the pathogen injection, obtained after the “refreshment” of the virus in animals, were used. The disease was reproduced by infection with the test suspension of the virus intradermally, subcutaneously, intravenously at a dose of 0.5 cm3 and titration on the skin of the animal. The effectiveness of the biological model was assessed by morbidity, severity of the course and severity of the manifestation of the disease. During primary intradermal infection with a field isolate of the virus, the disease manifested itself in one of three animals in the form of hyperthermia, depression, lacrimation, and the appearance of several nodular nodules in the skin of animals. The refreshed tissue virus caused clinical disease both in subcutaneous, intradermal and intravenous infection. But the clinical signs of the disease were more pronounced with intradermal inoculation of the virus, and with intravenous inoculation, it manifested itself in a more severe form with a fatal outcome. Inoculation of the virus intradermally into different areas of the skin led to the development of an independent skin lesion in each infected point in the form of painful edema, followed by necrosis, the size and intensity of which depended on the dose of the injected virus. This development of skin pathology made it possible to work out a method for determining the virus titer in vivo. The tissue virus obtained from the edematous tissue at the site of the pathogen injection was guaranteed to cause clinical disease in cattle during intradermal inoculation and made it possible to evaluate the immunogenic efficacy of the produced batches of vaccine against lumpy dermatitis.
