Annotation: The article describes two strategies of interface implementation. The first one, additional object properties of a class are set. The class inheriting interface and implementing its methods can definitely fulfill them. The second strategy of implementation is in closing methods of interface (making them private), specified the method name by the interface name.

Annotation: One of the directions of energy saving is the application of heat pumps by means of which it is possible to use low-potential, usually waste heat. The question of the possibility of using heat pumps in thermal power plants is considered in the present article. Also a diagram of possible use in thermal power stations of low-grade waste heat with heat pump installation is presented in the article.

Annotation: In this article issues of efficient use of ferroalloys production waste to save costs are considered; energy efficiency of agglomerate production is calculated; sintering heat balance data are presented by a case study of Aksu Ferrolloy Plant. According to the annual economic benefits calculation the folowing results are obtained: due to аglogases recirculation, fuel saving is 1334.5 t.o.e.; due to reheating it is 1491 t.o.e.; due to installation of thyristor converters to the unit the annual energy saving is 1714000 kWh. Thus, it is identified that besides energy-efficiency measures during recycling of solid and gaseous wastes, the use of agglomerate increases IPF electric furnaces performance as well, decreases specific energy and reducing agent consumption which means the prime cost of finished products will be reduced.

Annotation: The results of the analysis of influence of some main process factors on heat conduction of heat-insulating materials are given in this article. As major factors were considered: density, temperature, humidity. Researchers are conducted on the basis of the theory of planning of experiment. The got dependences of heat conductivity on a closeness and temperature of material show approximately equal influence of these factors on the exit of experiment

Annotation: The article considers the methods of rationalizing the process of heating the refractory materials of aluminum electrolyzers up in relation to thermal stresses arising in the hearth lining. The functional goals of the refractory materials are listed. The operational characteristics of the refractory materials are presented. During thermal influence on a hearth lining, the physical effects called thermal expansion occur. The materials which save their properties under high temperature are known as refractory materials. The thermostability is described in more detail. The scientific test bench was used to investigate ultimate strength. The method of temperature and pressure measurement when conducting the experiments is cited. In order to choose the potlining it is necessary to know the peculiarities of refractory materials and actual industrial loadings as precisely as possible.

Annotation: This article views the problem of professional readiness of a future teacher to the professional work. Much attention is given to the contemporary social and economic situation and the increasing role of the system of education. The readiness of a future teacher to the professional work is presented as a system containing such components as motivation, knowledge and skills. The conditions necessary for improvement the training of future teacher to their professional work have been specified.

Annotation: This article contains material on some issues of psychological readiness for maternity. The article highlights the main factors that determine the psychological readiness for maternity, need-motivational readiness for maternity, value-sense readiness for maternity.

Annotation: The article describes multilinguistic education issues in the framework of global experience. It reveals what is meant by multilinguism in European countries as well as measures taken for multilinguism to become standard. The article also presents a possible approach to carry out a monitoring research on multilinguistic education efficiency estimation in the Republic of Kazakhstan.

Annotation: The article reveals the issues of applying the competence approach in conditions of new development of educational paradigm. In particular, a great attention is paid to the issues of competence approach in training. The article also represents the essence of person-oriented training. The research of the stated issues is based on the theoretical works of the scientists who study the issues of education content. The thesis of the necessity to socialize educational process is proved in the article.

Annotation: In this article it is considered different definitions to “maternity” concept as well as moral and psychological aspects of students training for maternity which mean human perception of the whole set of requirements, duties, social standards of behavior. This training is oriented to increasing of responsibility of students before family life, social prestige of maternity, psychological readiness of students for maternity, obtaining succinct knowledge. The level of psychological readiness for maternity is determined by the combined effect of positive and negative factors influence by the moment when a woman becomes a mother.
