The work was carried out in 2020-2022 in conditions of insufficient and unstable moisture in the steppe zone of Kabardino-Balkarian Republic. Two experiments were carried out using growth regulators (without treatment; Albit, TPS; Bigus, VR; Tsircon, R; Epin-Extra, R; Ribav-Extra, R), as well as chemical (Spirit, SK) and biological fungicides (Fitolavin, VRK Baksis, Zh Kasumin 2L, VR Vitaplan, SP) in combination with the growth regulator (Gumi, R). As a result of the studies, the following indicators were studied: biological productivity, weight of 1000 grains, gluten content, susceptibility to yellow spot - Pyrenophora tritici-repentis (Died.) Drechsler, biological effectiveness of drugs. When using Epin-Extra, P, the weight of 1000 grains in the Yuzhanka variety was 40.7 g, when applying Bigus, BP on Pamyati Shatilov’s wheat - 42.4 g, Albit, TPS on the Taulan variety - 42.1 g with an average value of the indicator in the variant without drugs for all studied varieties was 37.8 g, with drugs – 40.4 g. On the Pamyati Shatilov variety, the growth regulator Albit, TPS, stood out, with the use of which the productivity was 6.0 t/ha, the increase over the control was 0.6 t/ha. The biological effectiveness of the chemical fungicide Spirit, SK on the Yuzhanka variety was 84.8%, and on the Pamyati Shatilova variety 89.1%. For the biofungicides Kasumin 2 L, VR and Fitolavin, VRK against pyrenophorosis, it was equal to 9.6% and 18.4%, respectively, which is much lower than for the chemical fungicide.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140386065","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 work was carried out on an installation with a hybrid-type chamber with adjustment of the microwave power level of the magnetrons and the duration of exposure. Two possible designs of a hybrid installation for processing lumber and polycaproamide threads are presented, differing in that in one the lumber was processed inside the chamber, and the polycaproamide threads were pulled through waveguides using bobbins and an electric motor installed outside the chamber, and in the second, both materials were processed inside the installation chamber. The object of research is lumber and polycaproamide threads. Lumber was loaded into the working chamber in the form of a stack, which rotated along its axis, and a structure was examined in which polycaproamide threads were pulled through a waveguide extending from a source of microwave energy outside the chamber. The time of exposure to microwave radiation on lumber and half-caproamide threads was measured using electronic stopwatches; temperature and humidity were measured using a Testo 905T2 thermometer, a Testo 830T1 pyrometer, and a Testo 606-1 digital hygrometer. The use of a hybrid microwave electrotechnological installation reduced the processing time of lumber due to rotation in the microwave field to 15 hours, while ensuring the required quality of the dried material (final moisture content - 7.1%, reduction in chipping and impact bending strength within 5%). The relative breaking elongation of polycaproamide threads increased by 48.2%, and the breaking load – by 27.6%. Thanks to the simultaneous processing of lumber and polycaproamide threads, it is possible to reduce metal consumption and increase the energy efficiency of the installation.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":" 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140386581","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}

To achieve this aim, it is necessary to develop and implement effective mechanisms to smooth out the abrupt growth of production volumes and ensure the sustainable development of agricultural sectors. The development of the agricultural sector of the Republic of Tatarstan shows positive trends in the growth of volumetric indicators of production over the past five years. The volume of gross agricultural output in the region increased with an annual growth rate of 21.62 billion rubles. At the same time, the volume of production growth in the crop and livestock sectors amounted to 11.11 and 10.49 billion rubles, respectively, which demonstrates the uniform development of the two main industries. The growth in volumetric indicators of product production is mainly due to the intensification of production processes, the introduction and development of innovative technologies. Along with this, abnormal weather conditions have a negative impact on the process of sustainable development of agriculture, as evidenced by the results of 2021, when the total production volume was only 80.1% of the previous year’s level, and crop production decreased by 38.7%. The identified trend once again emphasizes the need to search for adaptive methods of farming in accordance with climate change by moving at a more intensive pace to the creation of drought-resistant varieties, the development of moisture-saving technologies and the active implementation of reclamation measures. Livestock farming is developing at a more sustainable pace, although there is a decline in the numbers of certain animal species. However, this process does not affect production volumes due to increased animal productivity. The industry is in the process of gradually replacing low-productive animals with highly productive breeding stock. To transition to sustainable development of agriculture in the republic, it is necessary to continue work on adapting technological processes to climate change, creating and introducing new varieties, developing genetic technologies for animal breeding, using digitalization and robotization of the industry.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":" 44","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140385696","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 our work, we used two types of straw hydrolysates (after acidic and enzymatic hydrolysis), pre-activated by steam blasting at steam temperatures of 100, 165, 210 0C. The hydrolysates were diluted with distilled water to a concentration of reducing agents (RR) equal to 1.0, 1.5 and 2.0% of their mass in order to determine the rational concentration. Two cultures of anaerobic microorganisms were tested on 18 samples of hydrolysates: a strain of bacteria of the genus Clostridium Butyricum E.VI .3.2.1 (no. VKPM B-9619), a strain of bacteria of the genus Enterobacter cloacae (no. VKPM B-1980). The fermentation temperature for all samples was set at 37 ± 0.5 0C, pH 5.5 ± 0.1. The released gas accumulated in the gas tank; its samples were taken every 12 hours and analyzed for the volume content of hydrogen. After establishing the rational initial concentration of the substrate, the temperature of steam explosive activation of straw, the type of hydrolysate and the maximum yield of biohydrogen, the cultivation temperature and pH for each culture were further changed in order to determine the rational parameters: for Clostridium Butyricum, the cultivation temperature was set to 32 ±0.5, 37 ±0.5 and 42±0.5 0C for Enterobacter cloacae – 36±0.5, 37±0.5, 38±0.5 0C; the pH for all samples was set in the range of 5...6 in increments of 0.5 ± 0.1).

In the context of a sharp decline in the country’s budget revenues and an increase in its expenses, it is very important to organize the effective use of available resources, including financial ones. Therefore, it is very important to organize a system for regulating the use of budget funds through the system of organizing public procurement. Many enterprises consider this sector of activity economically profitable for themselves, since public procurement is associated with the provision of quality services in the healthcare sector, the agricultural sector and the social sphere, is a motivator of innovative development, a lever to combat environmental pollution, and also provides a factor in sustainable development. Starting in 2020, government procurement was transferred to electronic format. In a study conducted by the Institute of State and Municipal Management of the National Research University Higher School of Economics, which was published on December 20, 2021, an anonymous survey revealed that most representatives of business structures participating in public procurement encounter corruption during the competitive procedures. Based on the results of the analysis, it was revealed that open competition in electronic form and procurement from a single supplier (performer, contractor) are the most susceptible to corruption. And the best from the point of view of anti-corruption is an electronic auction, since it takes place in real time, which creates public control over the auction. As a result of the research, directions for openness and accessibility of information on public procurement for all interested parties, automation of the process of selecting a winner in a limited time without the influence of the customer with the participation of artificial intelligence were proposed. This will help increase the level of economic security of Russia in the field of public procurement.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":" 39","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140386119","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 study substantiates a system of indicators (coefficients of autonomy, provision of inventories with own funds, provision with own funds, ratio of borrowed and own funds, absolute liquidity, mobility of property, financial stability), used for an integral assessment of the financial stability of organizations. Determining the significance of these indicators was carried out using the method of correlation and regression analysis, carried out on the basis of data from a homogeneous set of related production enterprises in the Voronezh region. The integral indicator of financial stability was tested, rather wide limits for the integral indicator were identified and it was determined that the largest number of enterprises under study (57.9%) belong to the middle group in terms of financial stability. The proposed algorithm for calculating the integral indicator of financial stability will not only make it possible to timely and objectively assess the financial stability of an economic entity, identify emerging threats of a drop in efficiency and a slowdown in the pace of economic development, but will also provide greater objectivity in assessing the financial and economic activities of organizations and can be used in the basis for developing strategic plans for the development of the enterprise and optimizing the structure of financial resources.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140385530","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 functioning of the engine as a model can be presented in the form of a multi-level and multidimensional system in which the control flows will be indicators of the work process (effective power, indicator pressure, the amount of fresh charge entering the cylinders, etc.), fuel supply parameters (cyclic supply, fuel injection pressure, fuel temperature, etc.), which depend on the physicochemical and operational properties of the alternative fuel.

The social functions of the state ensure the quality of life and represent, in fact, all spheres of society’s life, therefore assessing the level of effectiveness of the social state is very important, but difficult due to its polycriteria and multi-level nature.

Depending on the characteristics of the transported raw materials, conveyors of various designs are used. Due to a number of advantages in the production of dry bulk feed mixtures for farm animals, it is rational to use horizontal screw dispensers of a closed type driven by asynchronous electric motors. To increase the life of asynchronous motors, their operating mode provides for smooth braking, which affects the accuracy of dosing feed components. In this regard, the purpose of the research was formulated – to determine the influence of the structural and technological parameters of screw dispensers on the amount of material to be moved during the braking of the screw. Calculations were performed for a standard DSh-60 auger using well-known laws of mechanics. When considering the calculation scheme, it was revealed that in the screw braking mode, the mass of the dosed materials is influenced by the material supply and the screw rotation frequency. The permissible ranges of the screw rotation frequency have been experimentally established when it changes in the braking mode, which are in the range from 94.8 min-1 to 18.7 min-1. As a result of the calculations carried out, it was revealed that as the screw rotation frequency increases in the specified range, the amount of material moved by it increases by 3.7 times. The lowest feed value for the screw in question is set, which is 0.8 kg/min (at = 18.7 min-1), and the minimum mass moved by the DSh-60 screw in braking mode is 19 g. Calculated values of the mass of the dosed component can be entered into the screw control program to adjust the dosing accuracy.","PeriodicalId":23526,"journal":{"name":"Vestnik of Kazan State Agrarian University","volume":" 30","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140386088","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}
