The purpose of the article is to show the formation of the student body of Katerynoslav Іinstitute of Public Education (КІPE) relying on the legacy of the predecessors and the existing sources; to highlight educational, scientific and socio‑political activities of КІPE students; to reveal their financial situation. Research methods: historical-genetic, historical-comparative, historical-typological, problem-chronological. Main results and scientific novelty: the main characteristics of the student body are comprehensively presented, the educational, scientific and socio-political activities of КІPE students are analyzed for the first time. Practical significance: in the process of research, a systematic factual base is created for a comparative analysis of the activities of public education institutions and analysis of statistical data of their student body. The originality of the study is based on a wide range of sources used and their analytical and synthetic processing. Principal results. The dynamics of changes in the student body of the institute, which was formed through a system of business trips, is analyzed. In the first years of the decade, the Bolsheviks failed to realize their ideas of dominance among the youth, workers, peasants, КP(b)U and KSMU members. The distribution of students by nationality was also quite original. There were almost equally Ukrainians, Jews and Russians among them. Perhaps because of this, it was not possible to ukrainize the university completely. Some students were engaged in scientific work. The authorities tried to impose the Marxist-Leninist ideology on young people. However, this work was not effective, primarily because in the first years of the decade, the Communists and the Comsomol members could not create their own centers because of their small numbers. Community work was concentrated in the student club. Student trade union organizations and centers of voluntary societies functioned. Students patronized units of the Red Army, conducted campaigns to eliminate illiteracy. The financial situation of the youth was difficult. It was difficult to provide students with housing, scholarships, food, and medical care. Article type: theoretical research.

The aim of the article is to highlight the evolution of ideas in Soviet and modern historiography on (non)perception of scientific traditions of the Kharkiv Imperial University by the Institute of Public Education named after O. O. Potebnya (KhIPE). Research methods: problematic-historiographic, historical-chronological, comparative-historical; principles of systematicity and objectivity. Main results and scientific novelty: for the first time it has been considered in detail how researchers assessments have changed from denying the necessity of mastering the old principles of higher education to the perception of the Kharkiv Institute of Public Education named after O. O. Potebnia as the heir of the pre-revolutionary university with partial preservation of traditions. The coverage in the historical thought of the 20s of the 20th and the beginning of the 19th century of problematic issues related to the establishment and operation of the KhIPE is analyzed. Particular attention is paid to the diversity of opinions and assessments of the KhIPE perceptions of the traditions of the Kharkiv Imperial University. The authors concludes that the traditions of the Kharkiv University were partially preserved in the work of the KhIPE, thanks to the inherited material base, and most importantly, the preserve of the main teaching staff, employees and part of the pre-revolutionary students. In the latter case, the years of 1921–1924 are meant, when some of students who had studied before the university closed in 1919 returned to study and non the latter case, the years of 1921–1924 are meant, when some of students who had studied before the university closed in 1919 returned to study and non-proletarian youth made up a significant proportion of the student contingent. In historical science the KhIPE’s estimation as successor to the Kharkiv University is unstable. Soviet authors focused mainly on the refusal of the leadership of the People’s Commissar of Education of the USRR and the IPE on the forms of the liquidated imperial university. Meanwhile, the contemporary authors, on the one hand, emphasize the voluntarism and failure of the educational reform and 1933 forced restoration of universities by the Soviet power. On the other hand, the idea that the tradition of the Imperial University was more than accepted until recently was considered to be in keeping with the KhIPE traditions. The article is dedicated to the 100th anniversary of the most radical reform in the history of domestic universities, the consequences and historical significance of which cause lively discussions among experts. The practical significance of the article is to change the priorities in teaching and promoting the history of the V. N. Karazin Kharkiv National University. The originality of the study is due to the unbiased consideration of a wide range of used historiographical sources (scientific works and journalism). Type of article: theoretical research.

Tribological properties of engineering components are a key issue due to their effect on the operational performance factors such as wear, surface characteristics, service life and in situ behavior. Thus, for better component quality, process parameters have major importance, especially for metal matrix composites (MMCs), which are a special class of materials used in a wide range of engineering applications including but not limited to structural, automotive and aeronautics. This paper deals with the tribological behavior of Cu-B-CrC composites (Cu-main matrix, B-CrC-reinforcement by 0, 2.5, 5 and 7.5 wt.%). The tribological characteristics investigated in this study are the coefficient of friction, wear rate and weight loss. For this purpose, four levels of sliding distance (1000, 1500, 2000 and 2500 m) and four levels of applied load (10, 15, 20 and 25 N) were used. In addition, two levels of sliding velocity (1 and 1.5 m/s), two levels of sintering time (1 and 2 h) and two sintering temperatures (1000 and 1050 °C) were used. Taguchi’s L16 orthogonal array was used to statistically analyze the aforementioned input parameters and to determine their best levels which give the desired values for the analyzed tribological characteristics. The results were analyzed by statistical analysis, optimization and 3D surface plots. Accordingly, it was determined that the most effective factor for wear rate, weight loss and friction coefficients is the contribution rate. According to signal-to-noise ratios, optimum solutions can be sorted as: the highest levels of parameters except for applied load and reinforcement ratio (2500 m, 10 N, 1.5 m/s, 2 h, 1050 °C and 0 wt.%) for wear rate, certain levels of all parameters (1000 m, 10 N, 1.5 m/s, 2 h, 1050 °C and 2.5 wt.%) for weight loss and 1000 m, 15 N, 1 m/s, 1 h, 1000 °C and 0 wt.% for the coefficient of friction. The comprehensive analysis of findings has practical significance and provides valuable information for a composite material from the production phase to the actual working conditions.

This study is devoted to the study of relevant works on the history of the Stavropol Cossacks, works in the field of education of the Stavropol Cossacks as an independent Cossack group, trade, cultural and economic ties in the Stavropol Territory, spiritual life, language, culture, traditions and customs of the Stavropol Cossacks. Among modern studies in the history of the Stavropol Cossacks, the following topics stand out: military life and everyday life, folklore and song traditions, the movement for the revival of the Cossacks, as well as the current state and prospects for the development of Cossack organizations. The prospect of the development of pedagogical technologies based on the Cossack traditions of educating young people in Stavropol is highlighted as a separate topical topic. The relevance of the study lies in the need for a private study of the historiography of the regional Cossack group of Stavropol Cossacks in order to expand the scientific and pedagogical tools in the field of «Cossack studies». The practical significance of the study is expressed in the possibility of using the data of the article in the search for supporting material for teaching the "History of the Cossacks" in a higher educational institution (taking into account the regional specifics). The scientific novelty of the research is expressed in a new view of the Stavropol Cossacks as an independent Cossack group formed at the end of the XVIII century. The source base is represented mainly by archival data from the State Archives of the Stavropol Territory, data banks on archaeological, cultural and linguistic expeditions, sources of personal origin, the works of contemporary historians and directly the works of historians, whose studies formed the basis of the historiography of the history of the Stavropol Cossacks. The research methodology is based on the principles of historiographic comparative studies and comparative analysis of sources. Within the framework of the sociocultural approach, we rely on the following methods. Special-historical: the narrative method, the historical-comparative method, the historical-systemic method, the retrospective method. Sociological: document analysis, method of generalizing characteristics, method of ideal types. Culturological: comparative method, cultural-systemic method. Pedagogical: pedagogical interviewing, a method of studying and generalizing pedagogical experience.

Subject of research. Biopesticides are based on live cultures of specially selected beneficial microorganisms with controlled properties. They have a pronounced phytoprotective and stimulating effect, thus providing effective prevention and protection of plants from diseases. The obtained biological product increases productivity, improves the quality and structure of the crop, does not accumulate in plants, which allows to obtain environmentally friendly agricultural products and does not harm the environment. Among the large number of bacteria, as a source of microbiological insecticide is Bacillus thuringiensis, which infects lepidopteran pests and leads to their death. Preparations based on this strain are effective when used in low concentrations of solutions. The Bacillus thuringiensis strain produces several toxins with insecticidal action, including β-exotoxin and δ-endotoxin. Toxic effect is manifested and leads to paralysis of the intestinal tract of parasites. Preparations β-exotoxin and δ-endotoxin are obtained by culturing Bacillus thuringiensis bacteria in a liquid medium. The scientific work proposes a method of industrial production using by-products of vegetable raw materials, which makes it economically feasible to use such substrates. The purpose of the study is the development of technology, formulation of nutrient medium, process parameters for the cultivation of bacteria of the genus Bacillus thuringiensis and obtaining a culture fluid containing substances of the class of biopesticides. Methods. Standard and generally accepted methods of research of bioproducts in biotechnology. The formation of bioinsecticides was established by hydrolysis methods, followed by determination of the component of β-exotoxin – ribose, the formation of octagonal crystals of exotoxin – by microscopic method. Research results. Three variants of nutrient media, which include yeast-polysaccharide complex: corn flour, corn oil, yeast autolysate were developed. The parameters of the bacterial cultivation process were studied. The final product is a paste or powder with a titer of 35 .109 spores in 1 g of the bioproduct. Scope of research results. Microbiological preparations based on Bacillus thuringiensis are highly specific and act only on insect larvae from the classes Lepidoptera and Diptera. The resulting biopesticide can be used against pests of a wide range of vegetable and fruit crops.

Parameter Approach

Conventional sensor structure design and related fracture mechanics analysis are based on the single J-integral parameter approach of elastic-plastic fracture mechanics (EPFM). Under low crack constraint cases, the EPFM one-parameter approach generally gives a stress overestimate, which results in a great cost waste of labor and sensor components. The J-A two-parameter approach overcomes this limitation. To enable the extensive application of the J-A approach on theoretical research and sensor engineering problem, under small scale yielding (SSY) conditions, the authors developed an estimate method to conveniently and quickly obtain the constraint (second) parameter A values directly from T-stress. Practical engineering application of sensor structure analysis and design focuses on three-dimensional (3D) structures with biaxial external loading, while the estimate method was developed based on two-dimensional (2D) plain strain condition with uniaxial loading. In the current work, the estimate method was successfully extended to a 3D structure with biaxial loading cases, which is appropriate for practical sensor design. The estimate method extension and validation process was implemented through a thin 3D single edge cracked plate (SECP) specimen. The process implementation was completed in two specified planes of 3D SECP along model thickness. A wide range of material and geometrical properties were applied for the extension and validation process, with material hardening exponent value 3, 5 and 10, and crack length ratio 0.1, 0.3 and 0.7.

All serious theoretical research in the field of communication shows that, under the influence of global processes of globalization, information is increasingly visualized and iconized. Young people communicate using the wide range of opportunities provided by digital technology and the Internet. We spend a lot of our time in the virtual space. Everything seems fraudulently easy - everyone in minutes can upload information that is rapidly becoming available worldwide. Even small children handle as computer technicians. At the same time, the majority of participants in this communication have a substantial deficiency in visual literacy. Even specialists often ignore the language of forms, colors and compositional organization of space, which requires serious preparation, training and continuous specialization. Worldwide there are no good examples, but unfortunately they are not yet available to the cultural community in our country. The report raises a number of questions and issues for discussion and tries to draw attention to possible ways of solution. Keywords: visual communication, iconography, language of colors and forms

Dear readers, authors and colleagues, Technological progress plays an essential role in the development of human society. The increasing global population and its mobility, the expansion of urban areas, climate protection and the conservation of fossil resources present challenges that can only be overcome by the improvement of existing resources and the development of new components, materials and production processes. Conventional materials have quickly reached their limit as new mechanisms are developed. These fields of application require the supply of new materials working in aggressive environments at extreme temperatures and high stress. These new materials are also expected to automatically alert us when critical loads are reached to avoid accidents caused by failures. This is the first issue of the Ziggurat Journal of Materials Technology, and we hope that you are satisfied with the content. The title of the journal primarily suggests materials technology; however, we strive to present a broad range of topics, including questions about the interaction between design, material, manufacturing and energy. The efficient interaction between these parameters results in components that are optimally designed and economically feasible. The idea for this journal resulted from the editors' realisation of the large knowledge potential that is being developed at colleges and universities around the world by scholars and PhD students. These clients must have the opportunity to publish their work and get in touch with other scientists. We want to reach out to young researchers and encourage them to present their work to a wide range of readers. Furthermore, a scientific career today requires evidence of publications that withstand the corresponding assessments of specialist colleagues and meet the criteria of good scientific work. In this context, the submitted articles will be subjected to a strict review. The principal objective is not to criticise work but rather to provide advice on how to improve the quality of the work presented. With this in mind, we would like to invite you to submit articles and use this journal as a reference for your ongoing scientific work.
