The efficiency of separating long flax fiber from the flax straw largely depends on the structural parameters of the layer of flax stems. Modern fluffers for flax strips create random distortions and intersection of the layer of flax stems under the pick-up drum. These disadvantages of existing machines are minimized in an experimental fluffer, in which a layer of flax stems moves over the pick-up drum with a kinematic mode indicator equal to one. Aim of the Article. The study is aimed at finding means and methods for preserving the structural parameters of the layer of flax stems when fluffing flax straw strips. Materials and Methods. Experimental studies were carried out according to existing and newly developed methods, and the analysis of flax fiber was carried out according to the current GOST standards. The experiments were carried out on the flax strips formed by the LC-4A flax harvester. After grass sprouted through the strips of flax stems, they were fluffed with the serial machine VL-3 and an experimental fluffer. For each variant, the necessary measurements of the main structural parameters of the stem strip and collection of samples for analysis were made before the unit passed and after fluffering the flax stem strip. The results of measurements and processing of samples were processed using the methods of mathematical statistics. Results. It was found that macro-bends of the original and processed flax strips were in all the experiments. At the same time, the range of changes in the curvature of the flax strip outside the cutoff frequencies expanded 2.3 times under the influence of the working tools of the serial tedder VL-3. The randomness of these pulsations was caused by an increase in the distortion and elongation of the flax stems in the strip by 6.0° and 6.9%, respectively. At the same time, the experimental fluffer produced the smallest changes in the structural parameters of the flax stem layer. The technological evaluation of the flax straw confirmed the advantages of the experimental fluffer in comparison with the serial VL-3, which has an average production of long fiber higher by 0.65% and 0.5 units of number. Discussion and Conclusion. The analysis of the obtained results indicates the practicability of fluffing flax strips by picking up and moving the stems from above the pick-up drum with its kinematic mode index equal to one.","PeriodicalId":53796,"journal":{"name":"Engineering Technologies and Systems","volume":" 2","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139143052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The amino acid composition of compound feed is of great importance in feeding all kinds of animals. The lack of one or another amino acid limits the assimilation of other amino acids, resulting in excessive compound feed consumption, deterioration of the metabolism in the bodies of animals and increasing of their susceptibility to diseases. The use of grain heaps of wheat in the early ripening stages as feed raw materials is a promising direction for the development of the fodder base that will provide a balanced amino acid composition of compound feed with a lower content of expensive fish meal, which is the main source of protein in compound feeds. Aim of the Article. The article is aimed at determining the optimal ripening stage of spiked cereals, at which a high content of protein and proteinogenic amino acids is observed. The proposed technology and technological tools for early harvesting of spiked cereals will reduce agrotechnical terms of harvesting, reducing losses from shatter losses, and get grain of enhanced nutritive value. Materials and Methods. To study the amino acid composition, 4 samples of a winter wheat grain heap were taken: the winter wheat varieties Admiral and Luchezar, the perennial winter wheat (trititrigia) variety Pamyati Lyubimovoy and the gray wheatgrass variety Sova. Harvesting the wheat of these varieties was carried out by a combing-threshing unit in 5 phenological stages (growth stages are presented on the BBCH scale): 77 – late milk ripeness, 83 – early phase of wax ripeness, 87 – gold wax ripeness, 89 – full ripeness, 92 – overripeness. Results. The results of analyzing amino acid composition of 4 samples of wheat grain heap showed a high content of almost all the amino acids studied in the phase of gold wax ripeness, except of aspartic acid and asparagine, glutamic acid and glutamine, and tryptophan. Discussion and Conclusion. Grain heap of waxy ripeness wheat is a promising grain raw material for the production of compound feeds, which will reduce the amount of expensive components, such as fishmeal.","PeriodicalId":53796,"journal":{"name":"Engineering Technologies and Systems","volume":" 12","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139143636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In previous decades, parental leave was traditionally perceived as a period with a clear functional load that does not go beyond family care. While modern women in this period are trying to combine family care and professional employment. The purpose of the paper is to study the practices of combining family care and professional employment during the period of parental leave for up to three years. Materials and Methods. The methodological basis of the study has consisted of: a gender approach explaining the reasons for the imbalance of social roles performed by a woman during parental leave; a socio-cultural approach describing gender relations as a cultural and symbolic construct and allowing to understand the process of constructing models of behavior of women during parental leave; an institutional approach that allows to highlight the action of norms and functions, regulating the period of parental leave. The article is based on empirical data obtained in the period 2019‒2022 among women of the Republic of Mordovia. The study was based on a qualitative and quantitative strategy: the method of semi-formalized interviews and a questionnaire survey conducted in 2022 were used. Results. The article has shown that the time of parental leave is perceived by women not only as an opportunity to fulfill the maternal role, but also as a resource for professional self-realization. The paper substantiates the need for a new understanding of the meaning of parental leave, significantly expands the understanding of this period in the life of a woman and a family as a whole.

Under conditions of high demand for rubber products, continuous modernization of technological processes of continuous production is carried out. One of the tools to control the physical and chemical parameters of the resulting product is the technology of multipoint feeding of controlling impurities that can significantly affect the molecular characteristics of polymers. However, it is difficult to experimentally select the technology of multipoint feeding of controlling impurities to achieve the given molecular characteristics of polymers.\u0000Aim of the Article. To create a methodology that allows using the tools of model system description to carry out directed regulation and construction of the technological process to achieve a given molecular weight distribution.\u0000Materials and Methods. For more accurate mathematical modeling of polymer synthesis processes, two approaches to the model description of the system under study are considered: 1) Kinetic approach. In this case, the developed algorithm is based on the method of moments in combination with numerical methods for solving systems of ordinary differential equations that characterize the change in the material balance for each reaction component. When describing large-tonnage production, a modular principle is proposed, according to which the kinetics model is supplemented by hydrodynamic regularities that depend on the reactor type. 2) Statistical approach (Monte Carlo method).

To present the results of research on the development of an operational method for determining the mechanical efficiency of diesel engines with batteryoperated electronically controlled fuel supply systems.\u0000Materials and Methods. The Bashkir State Agrarian University proposed and successfully tested an operational method for assessing the technical condition of diesel engines with direct-acting fuel equipment on their mechanical efficiency, which is determined by the performance of their fuel equipment adjusted using the diesel itself as an adjusting stand. The possibility of using the proposed method for diesel engines with storage fuel systems was investigated.\u0000Results. The accuracy of determining the mechanical efficiency of diesel engines by electronically controlled fuel systems of battery type can be affected by the features of their work – the correction of cyclic feeds by the electronic engine control unit depending on the technical condition of the cylinders and high fuel injection pressure. To test this hypothesis, there were carried out studies on a four-cylinder D4EA 2.0 engine of a Hyundai Tuscon car with a Common Rail type storage fuel system. The engine fuel supply system was supplemented with an electronic unit integrated between the injector and the standard engine control unit, which interrupted the transmission line of the control signal to the injector according to a given algorithm without the standard unit transition to emergency mode. It has been found that the proposed method can successfully determine the technical condition of the engine as a whole and of its individual cylinders (alternating disabled and working cylinders).\u0000Discussion and Conclusion. The proposed operational method for determining the mechanical efficiency can be successfully used for diesel engines with accumulator electronically controlled fuel supply systems.
