Waste-heat recovery of turbine condenser water Method
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.

Two strategies of interface implementation in the C# programming language
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.

Using new generation e-books in high school educational process, including faculty of teachers’ development
Annotation: The article describes that the effective management of the learning process new textbooks using need to create a model of teacher action. The created model explicitly takes into account the objectives, methods, learning outcomes. With its help solve the problem of the knowledge of the student. And the problem of managing the cognitive activity is settled.

Development of traing web portal for web-sites creation
Annotation: In the article the analysis of the author’s educational information system for web-sites creation is presented. This system contains the electronic course acquainting the user with bases of web programming and popular Content management systems (CMS) such as WordPress, OpenCart. Use of turnkey system for development of web-sites reduces financial and time expenditure for its crestion because the most part of necessary functions is already done by CMS.

Integral transformations method in soil freezing problems
Annotation: The method of integral transformations is used to study the process of bodies heating and cooling. As a result of theoretical calculations the regime of soil freezing depending on the ambient temperature was established. Laplace transformation is practically used to determing patterns temperature of constructed concrete dams, building grounds

Determining the percentage of metal in the catalyst
Annotation: This article focuses on the adsorption properties of Ni-PEG / ZnO and Cu-PEG / ZnO catalysts. For modern technologies require more efficient and cheaper hydrogenation catalysts. Create them only through the development of new scientific approaches to the preparation of supported catalysts, and most recently modified polymer catalyst as supported on a carrier, and unsupported, involving the study of new physical and chemical methods. To determine the percentage of metal in the catalyst was prepared and investigated the mother solution.

The estimation of consumer properties of bee honey represented in the retail trade network
Annotation: This article views the research methods allowing by the organoleptic and physical and chemical indicators to estimate the honey naturality and approximately determine its origin due to the results of the analyses. The factors influencing the quality of the produced honey have been considered and the chemical Вестник Инновационного Евразийского университета. 2015. №3 ISSN 1729-536X 167 composition of the useful components of honey has been studied. It is shown that Kazakhstani honey can be rather competitive at the world market and the main task is the increase the honey production without changing its quality.
