The article is devoted to the problem of forming and improving students' cognitive skills in connection with development of communicative skills. The aim of the article is to study the effects of designing supporting schemes of different types on development of students' cognitive and communicative skills in the process of learning a foreign language. The authors summarized research findings on regularities of foreign language learning by university students and revealed conditions of enhancing the effectiveness of this process. The authors have justified the necessity and appropriateness of supporting schemes application when teaching foreign languages that are analogues of inner speech universal subject codes. The authors came to the conclusion that one of the most efficient ways to form and develop students' cognitive and communicative skills is to involve them in self-education, provide them with an appropriate algorithm of conscious and independent work with information, with each stage being constantly self-controlled.
The aim of this paper was to analyze the high temperature embrittlement of TiNb IF steel using plastometric torsion tests. High temperature embrittlement in the temperature range 600 -1200°C is a problem mainly connected with additions of microalloying elements to steel and also with inhomogeneous and coarse-grained microstructure formed during continuous casting. Reduction of high temperature ductility can lead to cracks in the slab. These surface cracks can easily become oxidised, and then they do not fuse during forming operations. A significant decrease in hot ductility of the analyzed steel occurred in the stable austenite just above the temperature of 1100°C, where the number of rotations to failure (N f ) in the sample was lowest, at 28.4. The cavities ratio was 1.9%, which occurred mainly below the fracture line. At the bottom of the dimple transcrystalline ductile failure (DTDF), complex particles based on Al, Ti, Mn, S, N were observed. In this temperature range the embrittlement is mainly attributed to fine precipitation of sulfides, oxides, particulates based on microalloys as well as segregation of impurities on the austenite grain boundaries.
While implementing the bachelor’s program in the fields of compressors and refrigeration, modern educational standards provide for the teamwork competence developing. The purpose of this study is to propose a system of developing this competence for students of the Petrochemical Institute, Omsk State Technical University. The main idea of the research is the application of an integrated interdisciplinary approach to all the competences of the graduate, involving various forms and methods of implementing the system of training highly skilled engineers. The team-building competence is formed both during instruction time and extracurricular time: in research, internships, sport and other activities. In addition, the work experimentally revealed that the competence under consideration is consistent with both the requirements of employers and the need for students self-realization while studying at a university. The article presents particular examples of this competence development in the course of basic professional subjects, as well as of Foreign language and Physical education. In particular, the Foreign language course was extended for the students of the mentioned training programs in comparison with other students. As for physical education, team skills are formed in the classroom and through the students participation in various sport competitions. Besides, the article describes the results of students participation in the program “Young professionals of Russia”, WSR. In addition, the interdisciplinary Petrochemical Institute project of the summer school for the first-year undergraduates, fully implementing the principles of complexity and consistency, is presented in the paper.
The analytical method for determining the magnitude of the contact pressure in a cylindrical interference joint with shallow depth grooves is described in the publication. This method takes into account the geometric features and the relative position of the external members.
The calculated dependences are based on the Lame’s formulas are given in the publication. They can be used to assess the bearing capacity of the joint at any macrogeometry of the joint, independently of the number, shape, size of grooves and their location.
The method is different by simplicity and visibility. It provides sufficient accuracy of results for engineering calculations.
