The conditions for the antifriction coatings formation during finishing antifriction non-abrasive treatment (FANT) are analyzed. The requirements for this kind of coatings and the main criteria for assessing their quality are noted. A relationship has been established between the quality of the coating obtained with FANT and the technological factors that determine the conditions for contacting the tool with the treated surface. It is proved that the shape and size of microroughnesses of the treated surface determine the efficiency of the microcutting process and filling the microcavities with the rubbed material. Technological factors influence on the coating quality was investigated during FANT by implementing a multifactor experiment, as a result of which a connection was established between the technological parameters of the process (total friction path, load on the tool), as well as the length of the supporting surface with indicators characterizing the coating quality. Statistical models were obtained for mass transfer of antifriction material, area (continuity) of the coating and surface roughness at natural values of the factors, which made it possible to establish the studied factors influence on the optimization parameters. The analysis of the experimental scattering graphs made it possible to clarify the nature of the factors changes and analyze their mutual influence on the optimization criteria. Taking into account the inversely proportional relationship of the optimization criteria, the achievement of their maximum values at the same time is impossible, therefore, the values are taken according to the final result of the FANT process. The range of the studied factors values is established, the regularities of their change are substantiated from the point of view of the selected optimization criteria. Determination the rational values of the FANT process technological parameters will improve the antifriction coatings quality obtained by a friction-mechanical method.

Abstract This article presents the results of studies to establish the optimal entry width for an excavator working in conjunction with mobile crushing plants in the development of overburden of the Angren open pit. According to the results of the research, an analytical relationship was established to determine the maximum productivity of the mining system “excavator-mobile crushing-reloading-conveyor complex” with cyclical-flow technology. A structural diagram has been developed that allows you to select the type and determine the main technological parameters of the equipment with the selected criteria for evaluating the effectiveness of the complexes. It has been established that the choice of equipment for conveyor lines should be carried out taking into account the mutual influence of adjacent technological links of the central heating systems, including the influence of the excavator-crushing and crushing-conveyor complexes on the efficiency of their mutual functioning within the framework of the adopted system as a whole. A functional graphical dependence of the excavator performance on the face width was obtained, taking into account the relationship of all technological parameters of the face. It has been established that the maximum excavator productivity of 1478.1 m3/hr is achieved with an excavator entry width of 17.4 m for the conditions of the Angren open pit. The resulting schedule makes it possible to assess the possibility of increasing the operational performance of single-bucket shovel excavators under various conditions of work, as well as to continue the optimization of excavation.

As a research area, interior design took shape in the 20s of the last century, despite the fact that the practice of decorating living spaces dates back many hundreds of years. However, the "self-sufficiency" of design and its connection with architecture to this day is the subject of scientific discussions of urban specialists, historians, art historians, and anthropologists. The article discusses the leading artistic styles and trends that prevailed in architecture and design from the point of view of their mutual influence on each other. Time frame of the research: from the middle of XIX century to the first half of XX century. As a result of the research of foreign experience in the formation of interior design, the main stages of the movement development and its relationship with architecture in two formations were identified: activities directly dependent on architectural decisions, activities that determine the entire design process to a large extent: from the functional zoning of the premises to the features of the placement of utilities in the building. Entering the information era in art as a whole is characterized by the rejection of slogans that clearly delineate stylistic boundaries and determine the role of a designer in creating the living space. The determining factor influencing the integrity of the building’s appearance in a modern view is the harmony of the facade and the internal content, which was made possible thanks to the equal interaction of the architect and designer, starting from the first half of the 20th century.

This article studies the cognitive features of the “power” frame and its gender implementation in the historical tragedy by W. Shakespeare “Macbeth”. Here, the author examines the concepts of “frame” and “gender” in linguistics, studying different approaches to their definition. The relevance of this work is determined by the close attention of the contemporary linguistics to these concepts, as well as their place in the contemporary academic paradigm. The academic affirmation of the “frame” and “gender” concepts designates a new step in understanding the ways and peculiarities of the language interaction, consciousness, and culture, and, consequently, it shows new aspects of the relationship of linguistics with other sciences. Nevertheless, the problems of both frame and gender are not yet fully understood. This study allows describing in detail the essence of the frame “power” and showing its meaning, use, and ways of its gender implementation in fiction, which explains the novelty of this article. The study’s methodology is based on the cognitive-discursive analysis of the text, as well as on an integrative approach to the discourse study, which combines methods of both cognitive and gender linguistics, as well as the discourse analysis. Common research methods were used along with private linguistic methods. The application of cognitive-discursive analysis has significantly increased the depth of understanding of the “power” frame that dominates Shakespeare’s historical tragedy. This historical text presents the central theme of political tragedy: the overthrow of the rightful ruler and the usurpation of power. The motive for the seizure of power forms a thematic core and is presented from the usurpers’ point of view. In this article, the author observes the gender shift and duality of the female and male beginnings: Shakespeare puts the female protagonist, hungry for power, among men, thus the images of Lady Macbeth and her husband come into conflict with the gender characteristics attributed to them. The play clearly traces the main idea of Machiavellianism: the goal justifies the means. The results conclude that the “power” frame is the leading one in Lady Macbeth’s monologue, thus setting one of the main themes of this tragedy.

Innovative textile materials can be obtained by depositing different coatings. To improve the thermal properties of textiles, aluminum and zirconium (IV) oxides were deposited on the Nomex® fabric, basalt fabric, and cotton fabric with flame-retardant finishing using the magnetron sputtering method. An assessment of coating quality was conducted. Evenly coated fabric ensures that there are no places on the sample surface where the values of thermal parameters such as resistance to contact heat and radiant heat deviate significantly from the specified ones. Energy-dispersive spectroscopy was used for the analysis of modified fabric surfaces. Non-contact digital color imaging system DigiEye was also used. The criterion allowing one to compare surfaces and find which surface is more evenly coated was proposed. The best fabrics from the point of view of coating quality were basalt and cotton fabrics coated with aluminum as well as basalt fabric coated with zirconia. The probability of occurrence of places on the indicated sample surfaces where the values of thermal parameters (i.e., resistance to contact heat and radiant heat) deviated significantly from the specified ones was smaller for Nomex® and cotton fabrics coated with zirconia and Nomex® fabric coated with aluminum.

Рассматриваются результаты проведения экспериментальных исследований способа удаления окалины с поверхности стального листового проката. Предложен новый способ и устройство для очистки поверхности листового проката от окалины режущими пластинами, вращающимися вокруг оси, перемещающейся поступательно вдоль обрабатываемой поверхности. Пластины наклонены в направлении вектора вращения на угол до 10 градусов и упруго поджимаются к обрабатываемой поверхности. Это обеспечивает возможность в процессе очистки поверхности воспроизводить макронеровности листового проката. Приведены результаты экспериментальных исследований, построены математические и графические зависимости, описывающие влияние факторов процесса на эффективность очистки поверхности проката. Показано, что наиболее значимое влияние на параметр оптимизации оказывает сила воздействия инструмента на поверхность заготовки. Причем это влияние реализуется в прямо пропорциональной зависимости. Другие исследованные факторы, а именно: угол наклона пластины, скорость ее вращения и подача, оказывают значительно меньшее влияние на степень очистки проката. Эти исследования были необходимы с точки зрения определения конструктивных параметров силовых элементов как технологической оснастки, реализующей указанный способ, так и технологической установки в целом. План эксперимента был принят, исходя из реальных производственных возможностей индустриального партнера, и соответствовал классическим представлениям теории резания. Описанные результаты дают возможность планировать дальнейшие эксперименты по изучению направлений использования данного способа Here we consider the results of experimental studies of the method of removing scale from the surface of steel sheet products. We propose a new method and device for cleaning the surface of rolled sheets from scale by cutting plates rotating around an axis moving translationally along the treated surface. The plates are tilted in the direction of the rotation vector at an angle of up to 10 degrees and are elastically pressed to the treated surface. This makes it possible to reproduce the macro-dimensions of sheet metal during the surface cleaning process. We present the results of experimental studies. We constructed mathematical and graphical dependences describing the influence of process factors on the efficiency of cleaning the rolled surface. We show that the most significant influence on the optimization parameter is exerted by the force of the tool's impact on the surface of the workpiece. Moreover, this influence is realized in a directly proportional relationship. Other factors studied, namely the angle of inclination of the plate, its rotation speed and feed, have a much smaller impact on the degree of cleaning of rolled products. These studies were necessary from the point of view of determining the design parameters of the power elements of both the technological equipment implementing this method and the technological installation as a whole. We adopted the experimental plan based on the real production capabilities of the industrial partner and corresponded to the classical concepts of the cutting theory. The described results make it possible to plan further experiments to study the directions of using the method

Abstract. The aim of this work is to investigate the relationship between indicators of cicatricial digestion and linearity of cows. Methods. The research was carried out in the breeding enterprises of the Sverdlovsk region on the livestock of Ural-type cows. Cicatricial fluid was collected with an oropharyngeal rubber probe, and a wooden yaw was also used. Cicatricial content was assessed at the Chelyabinsk Interregional Veterinary Laboratory. The pH value was determined by the electrometric method, VFA – in the Markgam apparatus, ammonia – by the microdiffusion method. Ciliates – in Goryaev’s chamber and under a microscope, bacteria – under a microscope with the addition of sodium chloride solution. Statistical data processing was carried out in the Microsoft Office Excel 2010 program. Results. In terms of the number of ciliates and bacteria in the rumen fluid, the Montwick Chieftain cows, characterized by high productive qualities, had an advantage. In terms of pH and VFA, the Vis Back Ideal line was the best. There were no significant differences between the groups in terms of the amount of ammonia in the rumen. The best animals from the point of view of influence on cicatricial metabolism were the animals of the Vis Back Ideal and Montwick Chieftain lineage. Scientific novelty. Studies have shown that linearity is associated with cicatricial digestion in cows. The relationship of bull lines with indicators of cicatricial metabolism of cows has been determined for the first time. The food in the rumen is digested due to the action of bacteria, ciliates, and fungi. An environment has been created in the rumen for the active development of microflora. Bacteria are able to synthesize amino acids and vitamins. The proventriculus can contain up to 50 species of ciliates.

Introduction. The article compares the methods of researching political discourse with special attention to linguistic methods, in particular, to discourse analysis and cognitive and rhetorical approaches. These methods are widely used to study political speeches, statements, texts. Increasingly, political discourse is seen as a social phenomenon, not only at the discursive but also on the cognitive and rhetorical levels. The object of this study is methods of analysis of political discourse allowing to study the position of a politician in the discursive sphere and to identify the character of his audience. The subject of the analysis are examples from Joe Biden's political speeches, seen as an instrument of influence, persuasion in the process of speaking to the electorate. The relevance of the work is determined by the need to develop arguments to choose a particular approach to political discourse, especially cognitive and rhetorical, as well as discourse analysis, which allow to reveal veiled meanings of political statements and consider the methods of persuasion of the electorate.Methodology and data sources. The subject of the analysis are examples of Joe Biden’s political speeches, seen as an instrument of influence, persuasion in the process of speaking to the electorate. To compare approaches the study of political discourse, descriptive and comparative methods are used, the effectiveness of different approaches and methods is illustrated by specific examples of linguistic interpretation of discursive features of publications and speeches, revealing the ambitions of the politician most fully. A method of quantitative counting is also used.Results and discussion. The use of descriptive and comparative methods makes it possible to compare different approaches to the study of political texts and speeches, to discuss the relationship of heterogeneous methods, to identify the most effective methods of studying discourse. The result of the article was the conclusions about the effectiveness of different approaches to the study of the language of politicians at discursive, cognitive and rhetorical levels. Comparison of methods of research of political discourse distinguishes discourse-analysis among other methods of analysis. The use of discourse analysis to study political discourse reveals the functions of discourse, for example, manipulative, selective and combined functions related to political goals. The use of critical discourse analysis allows you to identify these functions most fully.Conclusion. The study of political discourse can be carried out at different levels, but the discursive level compared to cognitive and rhetorical levels is the most effective from a linguistic point of view. Discourse analysis allows to explore political discourse at more qualitative different level than rhetorical and other linguistic methods of research. Discourse analysis is presented as a method of researching hidden meanings in politics in this article.
