Objective: Development of proposals for modernization of old-type RU1 type axles for their further use. Methods: Structural analysis method was applied. Results: Proposals on further use of old-type RU1 type axles and expanding their operating life. Practical importance: The proposed modernization would permit expanding the use of old-type RU1 axles after modernization with new face bearing retention and reducing the demand for new axles which would contribute to reduction of axle defi cit in overall repair of wheel pairs.

The crystal and molecular structure of [Cr(S2CN(CH2)5)3].2 CHCl3 was found by the X-ray structural analysis method. The value R 0.090 was found for 1 131 observed independent reflections. The substance crystallizes in a space group of symmetry P212121 with the following unit cell dimensions: a = 0.8675 (6), b = 1.815(2), c = 2.155(3) nm. The experimentally observed crustal density was 1.48 Mgm-3 and the value calculated for Z = 4 was 1.51 Mgm-3. The CrS6 coordination polyhedron has the shape of a trigonally distorted octahedron, where the D3 symmetry is a approximately retained. The degree of trigonal distortion expressed as the projection of the chelate S-Cr-S angle onto the plane perpendicular to the C3 pseudo axis is Φ = 41.7° (Φ = 60° for an octahedron). The skeleton of the structure formed by the complex molecules contains channels filled with chloroform molecules. The specific type of complex-chloroform interaction consists of the formation of hydrogen bonds of the chloroform protons with the fully occupied pπ-orbitals of the sulphur atoms in the coordination polyhedra. The low stability and crystal decomposition can be explained by loss of chloroform from the channels.

Introduction. The article describes phraseological synonyms in Russian and Moksha subdialects on the territory of Mordovia. The subject of the analysis is the specific features of dialect phraseological units. The purpose of the study is to present a comprehensive description of the phenomenon of synonymy of phraseological turns in the considered subdialects. Materials and Methods. To achieve this goal, it employs various research methods, the main of which is descriptive one. In addition, it uses the elements of distributive and component analysis method. The language material was made up of phraseological units extracted by continuous sampling from the “Dictionary of Russian subdialects on the territory of the Republic of Mordovia”, Moksha-Russian dictionaries and field observations of the authors. Results and Discussion. As a result of the analytical review of the material, it is identified that in the phraseological units of both the Russian and Moksha languages develop synonymous series covered by the phenomenon of variance. The emergence of synonymous series is primarily associated with the renewal of the figurative basis of phraseological units belonging to the same topic. In the process of synonymous development of phraseological units, there is a search for a better image and linguistic means of constructing it while maintaining the unity of the logical side of the concept underlying it. Conclusion. The article is of practical importance, its results can be used in writing teaching handbooks on Russian dialectology, in teaching the course “Russian dialectology”, “Dialectology of the Moksha language” and corresponding courses for students majoring in Arts and Humanities.

<p>This paper discusses Kiki Sulistyo’s strategy for reaching position in Indonesia literary field. This research applied phenomenology and structural analysis method. Data were gathered by interview and objectification from social structure. The style of the writers’ poems and his consciousness toward Lombok were analyzed by phenomenology. The research result shows that Lombok literary field is denoted as the economy upside. Kiki Sulistyo denounces the world economy, thus moving within the production of a restricted arena. Kiki Sulistyo created literature as a movement, so he formed <em>Akar Pohon</em> community. Through this community, he generates a young poet and simultaneously undertakes a project of publishing works. Two anthologies of poetry he published brought him to the position of a legitimate poet. The legitimacy is given by poets, literary scholars, and institutions</p>

Object: To show the lack of wheelset operating life efficiency use in case traditional methods of wheel tread reprofiling were used in the process of repair works. To consider the possibilities of further improvement of this process on the basis of new reprofiling technologies, using the deep and high-speed grinding. Methods: The methods of wheel tread reprofiling were analyzed, the effective process solutions, based on theoretical conclusions and current practical knowledge, were studied. Results: Wheel set wastage in case of using the traditional ways of reprofiling was estimated. Preliminary parameters of wheelset reprofiling modes using high-speed grinding were estimated, providing for the increase in wheel set operational life and reprofiling performance enhancement. Practical importance: The appropriateness of rolling stock wheel tread reprofiling, by using the method of infeed high-speed profile grinding, was presented. The obtained results may be applied in the development of requirements specification for wheel tread reprofiling machine at repair facilities of the Russian Railways.
