08.00.13 Mathematical and instrumental methods of Economics
DescriptionTraditionally, control decisions are made by solving repeatedly the forecasting problem for different values of control factors and choosing a combination of them that ensures the transfer of the control object to the target state. However, real control objects are affected by hundreds or thousands of control factors, each of which can have dozens of values. A complete search of all possible combinations of values of control factors leads to the need to solve the problem of forecasting tens or hundreds of thousands or even millions of times to make a single decision, and this is completely unacceptable in practice. Therefore, we need a decision-making method that does not require significant computing resources. Thus, there is a contradiction between the actual and the desired, a contradiction between them, which is the problem to be solved in the work. In this work, we propose a developed algorithm for decision-making by solving the inverse forecasting problem once (automated SWOT analysis), using the results of cluster-constructive analysis of the target states of the control object and the values of factors and a single solution of the forecasting problem. This determines the relevance of the topic. The purpose of the work is to solve the problem. By decomposing the goal, we have formulated the following tasks, which are the stages of achieving the goal: cognitive-target structuring of the subject area; formalization of the subject area (development of classification and descriptive scales and gradations and formation of a training sample); synthesis, verification and increasing the reliability of the model of the control object; forecasting, decision-making and research of the control object by studying its model. The study uses the automated system-cognitive analysis and its software tools (the intelligent system called "Eidos") as a method for solving the set tasks. As a result of the work, we propose a developed decision-making algorithm, which is applicable in intelligent control systems. The main conclusion of the work is that the proposed approach has successfully solved the problem

THEORETICAL BACKGROUND TO THE SUBSTANTIATION OF LOADING A POTATO STORAGE CONTAINER
05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionToday, the main goal of the State Program is to ensure food independence of Russia within the framework of the Food Security Doctrine, which includes accelerated import substitution, namely the creation of new technologies in the field of potato storage, which in turn will reduce the supply of agricultural products from abroad. But, despite the existing success, the problem of potato losses during transportation and storage still remains in the Russian Federation, comprising from 30% to 40% of the grown crop, in many cases, by the end of storage, losses reach 60%. This article describes a container for transporting and storing potatoes in storage. The disassembled container is transported to the place of loading of the product, where it is mounted and loaded with potatoes. When loading containers for storing potatoes in order to reduce damage, various types of shock absorbers are used. One of the simplest absorbers is the rubberized fabric belts, which are deflected between the opposite edges of the container. The location of the belts, their width and the distance between them will determine the passage of potato tubers when they are loaded. Successful implementation of the presented design will help reduce mechanical damage to tubers and increase the safety of agricultural products

YIELD OF WINTER BARLEY OF VOLZHSKY PERVIY VARIETY DEPENDING ON DIFFERENT SOWING RATES
06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionThe article studies the effects of different sawing rates of witer barley on crop yield. The studies were conducted on the experimental field of the Federal State Educational Institution of Higher Education in the Nizhny Novgorod State Agricultural Academy at the Novinki training experimental establishment from 2015 to 2018 on light gray forest soils. The object of research was Volzhsky Perviy variety of winter barley. We studied different sowing rates: 2, 3, 4, 5, 6, and 7 million germinating seeds per 1 hectare. The predecessor was clean fallow. On average, over 3 years of research, we observed the seeds field germination rate of 84.0-84.5%. The survival rate of plants at harvest was quite satisfactory 51.4-69.3%. We have noticed that an increase in the seeding rate from 2 to 7 million units / ha has led to a decrease in survival rate of plants by 17.9%. The highest grain yield in the experiment - 4.47 t / ha was obtained at a sowing rate of 6 million germinating seeds per 1 ha. An increase in the seeding rate from 2.0 to 7.0 million germinating seeds per 1 ha has led to an increase in the density of the productive stalk from 252 to 367 pcs / m2. The number of grains per spike in the study varied within a narrow range from 38 to 39 pieces, whereas the weight of 1000 grains varied from 32.7 to 33.8 g. We observed high spike productivity from 1.260 to 1.303 g due to the high number of grains per spike. Volzhsky Perviy variety of winter barley, showed good tillering ability when cultivated in the conditions of the Nizhny Novgorod region. The coefficient of total tillering capacity varied from 2.03 to 2.78, whereas the productive tillering capacity varied from 1.99 to 1.42

EFFECTIVENESS OF USING MULTIKAN-6 WHEN GROWING YOUNG FOXES
DescriptionThe cost-effectiveness of animal husbandry in the conditions of Yakutia causes irreparable damage to viral diseases, such as salmonellosis, viral hepatitis, parvovirus enteritis and others. Based on this, in animal husbandry, increased attention is paid to the prevention of viral diseases. The work was carried out in the period from 2009 to 2012. in the conditions of LLC "Pokrovskoye animal husbandry" of the Khangalassky ulus of the Sakha Republic (Yakutia). Boning of young animals showed that all his indicators were higher for pups born in 2011. So body size and physique are rated higher by 15.15%, in males - by 20.58%. Hair color was better in females by 19.44%, in males by 22.66%. As a result, the classiness of the animals of the experimental groups was higher than that of pups born in 2010. The commodity properties of the animal products of experimental animals and its cost are consistent with the results of the valuation. The offset on the quality of the fur products of the experimental groups in 2011 was determined at 89.02%, which is higher than the 2010 results by 10.32%. The average cost of one fur of a silver-black fox in 2011 was 2225.62 rubles. Additional vaccination of the main herd of foxes in autumn against the viral diseases with the vaccine "Multikan-6" has a positive effect on the quality of the fur products. The economic effect amounted to 258.62 rubles per 1 skin of a silver-black fox (at 2020 prices)

Description
The article demonstrates the results of therapeutic and preventive effectiveness of the use of lactic acid bacteria – Lactobacillus brevis and Lactobacillus parabuchneri in laboratory animals, in particular mice and rats. They were isolated from the gastrointestinal tract of a wild quail in experimental violation of the intestinal microbial background. Artificial imbalance of the intestinal microbiota of experimental animals was caused by the use of the antibiotic. As a result of tests it was established that the application of probiotic cultures improved microbial disorders of the gut, however, the use of their consortium in the probiotic promoted consistent clinical result characterized by an elevated level of representatives of the normal flora (lacto- and bifidobacteria) and reduction of the number of representatives of pathogenic and conditionally pathogenic microbiota, with subsequent achievement of a level characteristic of healthy animals
