Authors: Saidova Mukhabbat , Nematov Abror , Bafaev Bakhrom
Published: June 2023

The paper presents comprehensive research allowing to solve a scientific problem of great national economic importance. The authors describe the issues of interaction of the blade microteeth with the cut material of half-finished food products in order to improve the process of sliding cutting of food materials, considering the simultaneous penetration of the cutting wedge of the knife in the feed direction and the contact effect of the blade microteeth during its tangential movement. The high efficiency of sliding cutting can be ensured by an optimal combination of kinematic, geometric and microgeometric characteristics of the work members of cutting and knife grinding machines. The result of the work shows that when designing cutting machines, it is advisable to focus on the values of the slip coefficient, which ensures the separation of the half-finished product in the sliding cutting mode with minimal energy consumption.

The most important link in modern farming systems is the protection of crops from weeds. Only by taking effective measures to reduce the weediness of crops one can get a high yield of cultivated crops and high-quality products. On a field or plot with high weediness all other agricultural activities aimed at increasing crop yields will be ineffective. When planning for weed control, the grower must give priority to preventive and organizational measures. It is much easier to prevent weeding of agricultural land than to try to weed an already weeded area. Preventive measures include: seed cleaning; preparation of feed for feeding, allowing them to be cleaned of viable weed seeds; preparation of organic fertilizers (manure, composts) before applying them to the fields. An important measure that reduces the weediness of fields is the destruction of weeds on lands adjacent to fields: on unused plots, field edges, roadsides, edges of forest belts. Cleaning of weed seeds from wastes is necessary by means of agricultural machines and vehicles, as well as by means of containers.

Published: June 2023

The analysis of the Russian population nutrition shows that it does not correspond to modern concepts. It is characterized by high calorie content, insufficient intake of macro-and micronutrients. The purpose of the paper is to study the possibility of using mushrooms in the technology of making wheat bread. The work was carried out in 2022 based on the Kursk State Southwestern University. The use of mushroom powder in the production of bread necessitates its evaluation by the main organoleptic and physico-chemical indicators to develop an effective technology to create new types of products. The most effective concentrations of mushroom powder, which improves the physical and chemical parameters without losing the organoleptic value of the products, have been determined. The substantiation of prescription-component solutions for the use of dried ground mushroom - champignon in baking wheat bread is given. The influence of mushroom powder on the organoleptic and physico-chemical parameters of the finished wheat bread has been established. It was found that the optimal amount of mushroom powder to add to the dough is 6% of the total mass of flour. The results of physico-chemical analysis showed that wheat bread with the addition of mushroom powder meets the requirements of the standard. The results obtained allow us to recommend the developed method for the production of bread at enterprises.

Published: June 2023

The paper presents the results of studying the influence of the season on the change in the physico-chemical and amino acid composition of milk obtained from black-and-white cows. During the analysis, it was revealed that the composition of milk throughout the year was not constant. The highest fat content in milk was produced in autumn and winter, while the highest protein content was found in spring and summer milk. The amino acid composition of milk in the autumn-winter period is higher compared to the spring-summer period, which is due to a change in the diet, namely the predominance of concentrated feeds in winter. Based on the data obtained, it can be assumed that the milk produced by JSC named after Kirov, meets all requirements and can be recommended for the production of high-quality food.

Published: June 2023

Currently, the issue of developing adaptive varieties of crops based on evolutionary principles is becoming urgent. The need to develop adaptive varieties for Russia is determined by the contrast of its natural and climatic conditions, global climate changes, and the increasing unpredictability of the weather. This task is highly relevant to the valuable food crop buckwheat, the yields of which are still low due to insufficient resistance of modern varieties to extreme environmental factors. Vegetation experiments to study the genotypic reaction of light and dark phases of photosynthesis of leaves on changes in soil moisture availability were carried out. During the period of buckwheat breeding from local samples to modern varieties the plants showed a significant trend in increasing the activity of photosynthesis and transpiration of plant leaves with a certain decrease in their resistance to moisture limitation. It was established that a decrease of soil moisture content from 70 to 30% of total moisture capacity caused, in modern cultivars, a mean decrease of fluorescence quantum yield by 52.5%, of electron-transport chain activity by 53.7%, of photosynthesis intensity by 66.5%, of transpiration intensity by 82.1%, whereas in local cultivars it decreased by 40.0%, 52.1%, 51.0%, and 76.1%, respectively.

Authors: Musaev Sayfullo , Samiyeva Gulnoz
Published: June 2023

The paper studies the surface morphology of the initial polymers and the mixture using a scanning electron microscope SEM - EVO MA 10 (Zeiss, Germany). The X-ray phase analysis was carried out on a Panalytical Empyrean diffractometer. It has been proven that polymer mixtures based on domestic suspension polyvinyl chloride and ethylene-vinyl acetate copolymer, obtained by the method of "thermomechanical" mixing, are two-phase systems consisting of a phase of polyvinyl chloride and an ethylene- vinyl acetate copolymer. It was concluded that suspension polyvinyl chloride is fundamental in this system, which determines the main deformation-strength properties of the mixture. In the process of mixing a certain ratio of copolymer and thermoplastic, two-phase systems are formed, that is, mechanical mixtures of technologically compatible polymers with very close values of solubility parameters are formed. It has been determined that polymer mixtures based on domestic suspension polyvinyl chloride and an ethylene-vinyl acetate copolymer, obtained by the method of "thermomechanical" mixing, are two-phase systems consisting of a phase of polyvinyl chloride and an ethylene-vinyl acetate copolymer.

Published: June 2023

Descriptions of methods and results of experiments on the preservation of geometry and dimensional parameters of compressed wood using chemical and physical methods are given. Wide ranges of substances were used as chemical stabilizers in urea aqueous solution (plasticizer during pressing). Wood treatment with ultrasound, liquid nitrogen and pulsed magnetic field was used as physical methods. Urotropine, urea-formaldehyde oligomer, phenol-formaldehyde resin, butyric anhydride and physical methods (liquid nitrogen and pulsed magnetic field), as well as ultrasound can be applied to increase form stability of pressed wood to the level of swelling in water and water absorption of natural wood (respectively, 15-20% and 30-45%). Cashew nut shell liquid is recommended to obtain stable pressed wood. The liquid, with a content of 6-12% (by dry residue) relative to the mass of dry wood during heat treatment in the temperature range of 150-155°C for 8 hours, gives limiting volume swelling 7-8% and limiting water absorption 14-18%. Fully stable compressed wood was obtained after exhaustive acetylation with acetic anhydride and subsequent maximum impregnation with phenol alcohols (more than 70% of content) and thermocatalytic curing. However, this method cannot be recommended due to high toxicity and material weakness.

Published: June 2023

Comfortable temperature conditions in any room are provided by heating systems, thermal insulation properties of enclosing structures, external environmental conditions. Practical experience, literature analysis show that the existing temperature control systems in industrial premises have disadvantages. Eliminating is possible by using a multi-circuit functional control structure, allowing to reduce the inertia of the temperature control system by taking into account the outdoor temperature, the influence of natural light on the temperature inside the production facility. For its operation, a practically oriented mathematical model is needed, which allows taking into account the influence of a large number of external factors on the temperature regime with minimal delay. A mathematical model has been developed for use as a program in industrial electronics devices for predicting, correcting the temperature field, regulating the temperature regime in the production areas of a room at any point. Based on experimental data, the analysis of the results of the adequacy of the mathematical model shows that the temperature values obtained by the mathematical model of forecasting, correction of the temperature regime fall within the confidence interval and are within the standard deviation. The mechanism of technical implementation is proposed and the prospects of its use are shown.

Authors: Solonshickov Pavel
Published: June 2023

With the development of farms, by analogy with developed Western countries with well-established agricultural production, certain hopes are placed on solving the domestic food problem. It has been established that there are very few power tools for small-scale mechanization and agricultural implements for them. However, the domestic industry can provide almost complete mechanization of processes and bring it to a comprehensive one. It is also known that without solving this problem, that is, without a high level of mechanization of production processes, it is impossible to achieve high performance in the functioning of the farm. The domestic industry has now developed and put into production various power tools for small-scale mechanization. As new equipment is developed and put into production, both the quantitative and qualitative (type and structure) composition of the power equipment fleet and the set of agricultural machines for them change. The article deals with the installation for the preparation of liquid feed mixtures with the continuous introduction of components. This mode is one of the modes of any mixer.

Authors: Minnegalieva Chulpan , Gainullina Alina
Published: June 2023

Forecasting in the energy sector is of great importance for suppliers and for consumers. Optimum power consumption depends on many factors. Due to natural or any other external conditions, accidents are possible. In order to minimize emergency consequences, it is necessary to be prepared for possible outages in advance in order to reduce the time for their elimination and decision-making. This article considers the problem of forecasting power outages at substations. The enterprise provided a summary table of outages at substations due to natural disasters on specific days. To solve the problem, a machine learning method was chosen – binary classification. Five different algorithms were considered. The models were tested on data from the first half of 2022. The most effective algorithm for 20% of the test sample was the binary classification algorithm using generalized additive models (GAM). This algorithm is also one of the best with a sample of 50%. A model has been prepared for further use in predicting the probability of outages at the enterprise. The model can be used in other organizations; for this, it is first necessary to train the model on the data of the corresponding region.

Published: June 2023

The article presents the results on the species composition of the segetal component in different climatic zones of the Tyumen region based on an assessment of research data in the period of 2017-2019. The study of weed flora was carried out in crops of spring wheat in the Aromashevsk and Tyumen regions. The weed component in spring wheat crops is represented by species that are most often observed in these areas during phytosanitary monitoring. At the same time, the greatest variety of plant species adapted to grow in agricultural crops was recorded in the conditions of the northern forest-steppe. During the years of research, early spring segetal plants were most widespread, their number in the tillering phase of spring wheat was the highest among other biological groups. As a result of the research, it was determined that the change in the composition of the segetal component in the agrophytocenosis of spring wheat depends on the climatic and soil conditions of the study area.

Published: June 2023

The aim of the research was to establish the productivity of pasture ecosystems on the sandy lands of the Don basin. The objects of research are herbaceous plant communities on the sands of the Ilovlinsky massif of the Volgograd region. The analysis of the species diversity of the vegetation cover, its variability in space was carried out by an inventory of 5 test plots measuring 10 x 10 m. Generally accepted methods of statistical analysis, graphical interpretation and scientific generalization were used to process, analyze and present the results. In all the surveyed sites, there is a low proportion of Fabaceae family species (0-8 %), a large proportion of the mixed grass group (58-75 %) and the weed species of plants (26-50 %) species. The feed mass consumed on average in the plots is 11-45 g / m2. A direct relationship was revealed between the influence of the percentage of Poaceae and Cyperaceae (Carex) species in the phytocenosis on medium-grown sands on the increase in the yield of sandy pastures (g / m2) in the late autumn period (r = 0.99). The condition of the soil and vegetation cover on forage lands is a consequence of overgrazing.

Published: June 2023

In the manuscript, the authors described the results of the evaluation of the Columba livia population in Yoshkar-Ola (Russia). In the period from 2018 to 2022, the population density of pigeons in the city center increased by 15% and amounted to about 1,000 individuals per km2. The increase in the number of C. livia is not safe for humans. C. livia are most active during the day at permanent locations where they are fed by people. Of the five color morphs, dark-gray prevails. Pigeons belonging to the dark-gray morph are the most adapted to life in urban conditions. As part of the first phase of the project "Watch out, ornithosis!" from the Presidential Grants Foundation of the Russian Federation we conducted a survey of the citizens. As a result of the survey, we identified risk groups of the people due to ignorance about the features of the disease ornithosis. Older people feed pigeons more often and do not know about the diseases that birds carry. Schoolchildren also do not know about ornithosis. The next stage of the project will be the dissemination of preventive information about ornithosis and other diseases carried by pigeons, preventive measures.

Small molecules of plant origin can have different effects on bacterial cells. At present, it is of great interest to determine the toxic effects of such compounds in order to assess the potential of their use in veterinary medicine and medicine. The aim of this work was to evaluate the toxicity of various chemically synthesized small molecules of plant origin using a bacterial luminescent biosensor based on Escherichia coli and a cell culture of the freshwater ciliate Stylonychia mytilus. Cinnamic aldehyde had the greatest toxic effect on the E. coli MG1655 pXen7 lux-biosensor, which was expressed in a significant decrease in the luminescence level of the strain compared to the control. Quercetin in the concentration range used did not affect the luminescence intensity of the lux-biosensor. Coumarin and vanillin were characterized by a similar manifestation of the toxic effect. Similar results were also confirmed using S. mytilus as a test object. The results obtained expand the understanding of the possible toxic effect of phytochemicals, which can be used in the development of feed additives in animal husbandry (as analogues of feed antibiotics).

Authors: Esin Mikhail , Ruchin Alexander
Published: June 2023

Seasonal rhythms have been found in practically all groups of insects, but in Diptera they have been studied to a lesser extent. In deciduous forests of the European part of Russia (Republic of Mordovia, Temnikov district) seasonal dynamics of Diptera abundance was studied in 9 families (Tipulidae, Lonchaeidae, Aulacigastridae, Milichiidae, Heleomyzidae, Anthomyiidae, Muscidae, Fanniidae, Calliphoridae). Two peaks in seasonal abundance dynamics were characteristic of Tipulidae, Heleomyzidae, Fanniidae. Anthomyiidae had one peak in early June. Milichiidae had one peak in July. Muscidae had one peak in mid-August. Lonchaeidae and Aulacigastridae had a three-peak pattern with the highest abundance in June. Calliphoridae experienced a gradual increase in abun-dance from June and had a peak in early September. Numbers of Phaonia pallida (Muscidae) were at a minimum in June at different heights from the soil surface and gradually increased with peaks in August and September. The first individuals of Thricops simplex (Muscidae) did not appear in the traps until the first half of July. Thereafter its numbers increased very rapidly and reached a maximum in early September.
Morphometric parameters of the stem of lodging-resistant spring triticale in the conditions of the West Siberian region
Authors: Grebennikova Irina , Chanyshev Damir
Published: June 2023

In the course of field and laboratory research, selection samples of spring hexaploid triticale were studied for their selection-valuable traits and lodging resistance. The correlation analysis revealed a correlation between the individual traits that determine lodging tolerance. The most stable relationship of lodging resistance is with the length of the second and third internodes and the breaking strength of the straw. An additional selection criterion for lodging resistance is the sum of the lengths of the 2nd and 3rd internodes. Non-lodging varieties with high grain productivity that have significant differences in architectonics have been identified. These samples can be promising in lodging resistance selection without the involvement of sources of short stalkedness, having a number of negative traits.

The intensive development of forest areas in the Russian Federation leads to the need for a significant amount of work related to reforestation. High-quality soil preparation is the key to successful survival of forest planting material of economically valuable species. Traditional technologies of forest soil preparation by dump plowing are outdated today and do not allow to radically increase the level of labor productivity. In the work, calculations were made of the power costs required for soil preparation in the process of mineralization by a forest plow of the PLP-70 type. It has been established that a standard tractor of the Onezhets-300 series, when moving with a plow in a cutting area with simultaneous cutting of shrubs and small forests, allows for confident processing at a speed of no more than 0.3 m/s. This ensures productivity up to 1.5 hectares per shift. To ensure the growth of shift output up to 3.5...4 ha per shift, the required tractor power is at least 250 kW. Domestic serial forestry tractors cannot provide productivity growth, since they have an internal combustion engine power less than required.
