Authors: Sabiev U K , Golovin A Y , Soyunov A S , Demchuk E V 
Published: January 2022

Abstract
The work of produced domestic grain cleaning machines is based on the reciprocating motion of the sieve mills. The increase in the productivity of such machines by traditional methods has exhausted itself. Therefore, agricultural enterprises of the country of various forms of ownership need high-performance innovative grain cleaning machines for post-harvest grain processing. The article studies the various methods and solutions that affect the intensity of the grain separation process and increase the qualitative and quantitative indicators of the operation of grain cleaning machines. According to the performed theoretical studies, the completeness of separation on the surface of the sieve depends on the probability of the passage of the grain through the oblong hole of the flat sieve, located at an angle, when interacting with the long edge, performing reciprocating oscillations. It is theoretically determined that in the range α’ from 0 to 20° the probability of the passage of a particle increases from 0.315 to 0.548 or by 1.7 times. At the same time, as shown by the production check of the operation of the sieves of the proposed design, the productivity of the grain cleaning machine increased by 23 %, and the quality of cleaning the grain mixture meets the agrotechnical requirements.

Estimating the reliability of forestry machine elements with possibility theory application
Authors: Skobtsov I G , Shilovskiy V N , Dobrynina O L 
Published: January 2022

Abstract
The working conditions of forestry machines differ from those of agricultural machines. The presence of obstacles during the clearing of forest areas increases loading of machine components and assemblies and, consequently, leads to their failures. This paper deals with an improvement of probabilistic methods of forestry machine design by applying fracture mechanics and possibility theory. The main fracture mechanics expressions linking stress intensity factor with crack-like defect length are presented in the introduction. Fracture toughness and crack-like defect length are viewed as Gaussian random values, maximum applied stress is presented as a fuzzy variable with unknown distribution law in the second part of the paper. Analytical equations for reliability evaluation are obtained by estimation of upper and lower bounds of reliability function. The real value of reliability function is located within this interval. The proposed approach may be applied to give recommendations for engineering of forestry machine and equipment elements in the case of limited statistical information.

Published: January 2022

Abstract
The article proposes an analysis of long-term studies to identify the effectiveness of the gradient magnetic field (GMF) on the growth and yield properties of spring barley. The experiments were carried out in Ryazan region of the Russian Federation on dark gray forest soils. According to the results of the experiments, it was revealed that the use of GMF for seed treatment before sowing contributed to an increase in the intensity of growth processes. Treatment of barley seeds before sowing with a gradient magnetic field, compared with the control, contributed to better plant survival and an increase in density by 2.2 %. In the variant with the use of a magnetic field, a higher volume of the photosynthetic apparatus was noted in all stages of the crop development compared to the variant without pre-sowing treatment. It was higher by an average of 17.14 % in the tillering stage and by 6.98 % in the booting stage. In the variant with seed treatment, barley plants were distinguished by an increased degree of tillering. On average, the maximum productivity was in the variant with pre-sowing seed treatment with GMF, where the increase in yield to the control values was 4.6 dt/ha or 12.7 %.

Published: January 2022

Abstract
The change in the redox potential of water and solutions of bovine serum albumin and gelatin in electrochemically activated water with a reduced value of the redox potential obtained in the cathode chamber of a diaphragm electrochemical reactor is considered. The dependence of the relaxation rate of a protein solution in electrochemically activated water on its concentration in the range 0.01%-0.2% is shown. An increase in the concentration of proteins contributes to the restoration of the RP of solutions with different kinetics for albumin and gelatin. Reagent-free control of the characteristics of protein solutions can find application in technologies for processing livestock products, for example, in meat technologies.

Abstract
The purpose of our research was to monitor the safety and quality of slaughter products of cattle and small cattle obtained in the conditions of the Aktobe region. Under certain conditions, animal slaughter products can be a source of not only typical infectious and invasive diseases in humans (echinococcosis, cysticercosis, etc.), but also various food diseases, which include toxicoinfections and toxicoses. Toxicoinfections and toxicoses are a large group of mainly acute food diseases of people. The very names “food diseases”, “food toxicoinfections”, “food toxicoses” indicate that the main role in their occurrence is played by food products. The consistency of the meat, the smell, the state of the muscles on the cut, the transparency and aroma of the broth, the pH of the meat of a healthy animal and a sick animal, the calculation of CMAFAnM, the amount of BGCP in 0.1 grams of the test product, the number of Salmonella bacteria in 25 g of the test product were determined. According to the results of the organoleptic examination, a conclusion was made about the freshness of the meat. Meat of cattle and small cattle, classified according to the results of organoleptic evaluation and bacteriological examination as meat of questionable freshness, is subjected to chemical and microscopic analyses. At present, with a variety of producing enterprises, various forms of ownership with a possible violation of technological production modes and violation of sanitary standards, poor-quality meat of cattle and MSS can enter the consumer market, which can become a source of various infectious and invasive diseases. Therefore, the quality expertise of this product group is very important and relevant.

Published: January 2022

Abstract
The basis for planning the activities of the agro-industrial complex and justifying their development in the future is the availability of natural resources. Water resources are an important component of the natural resource potential of the region, playing a key role in the development of an integrated agricultural economy. In determining the environmental sustainability of water bodies, the study of quantitative indicators of moisture resources and their spatial and temporal variability is of paramount importance. The correct presentation of resources and natural water reserves is the key to the successful development of economic sectors and the basis for the geo-ecological substantiation of the territory. A feature of the water resource potential of the Omsk region is the uneven distribution of atmospheric humidification over the territory, which, together with seasonal and long-term fluctuations, can serve as the basis for the manifestation of negative consequences of water. The paper analyzes the alternation of wet and dry years in the long-term period and their influence on the moisture content of the territory. Based on abbreviated summary curves, the duration of periods of continuous dry and wet years are shown, and the trend of long-term changes in the amount of precipitation in the study area.

Published: January 2022

Abstract
The Nura River basin is located on the territory of Central Kazakhstan and is a single territorial-production structure with a developed industry that plays an important role in the economy of the entire Kazakhstan. Effective industrial development should be based on the well-tailored farming industry. However, significant continentality of the target basin, along with orographic conditions, predetermines high heat and power and scarce water resources, which negatively affect the crop productivity. The paper analyzes the current status of land reserves nearby the Nura River basin, with due account for climatic conditions and water availability, considers the modern composition and structure of cultivated areas, indicating the leading sectors constituting the farming industry, and also outlines the main directions and prospects for the development of agriculture for the coming period. It provides the rationale for sustainable agriculture along with industrial development of the basin. Due to the location of the basin in the zone of dry steppes and semi-desert zones, the paper shows the need to use irrigation reclamation as the main way to increase the crop yield.

Published: January 2022

AbstractThe distribution of the golden potato nematode in the soils of the Omsk region has been recorded since 2003. The potential danger of expanding the area of colonization by this phytohelminth is associated with a loss of potato yield from 30 to 90%. Of the 32 districts of the Omsk region, 21 districts were found to be populated with the golden potato nematode. Potato production in the Omsk region is mainly carried out by private individuals. In many districts of the Omsk region, the share of personal subsidiary plots in the produced potatoes reached 95%. The studies were carried out in 2017 - 2020 and it was found that cysts with viable larvae of the golden potato nematode were detected in the samples of the studied soil samples, the degree of infection was high and ranged from 50 to 90 cysts. Under these conditions, the priority direction of reducing the number of phytohelminths is the use of environmentally friendly methods of control, such as the fungal microbiological preparation Nematofagin Mikopro. In the areas with the use of a biological product, the degree of infection was average and ranged from 45 to 13 viable cysts.

Abstract
The aim of the work was to determine the influence of mineral nutrition on the growth, development and quality of lawn grasses of a football field in the southern regions of Russia. The experiment was carried out on the site of the VGAFK training ground (Volgograd). Water-soluble fertilizers were used: foliar dressing; instant: Urea + Potassium Magnesia, Fertika. The composition of the sown grass mixture: Lolium perenne variety Vesuvius (20 %), Lolium perenne variety Eurocurdus (20 %), Festuca rubra variety Dorianna (20 %), Poa pratensis variety Markus (20 %), Poa pratensis variety Limousine (20 %). Lawn quality was assessed using two methods: A.A. Lapteva and NTEP (National Turfgrass Evaluation Program). The frequency of mowing the lawn will vary depending on light conditions, soil temperature and humidity. But there is a clear dependence on additional mineral nutrition. When applying fertilizers, mowing the lawn should be done every 5-7 days. Without additional mineral nutrition, the haircut should be done once every 7-12 days. It is important that when cutting, 1/3 of the leaf surface is cut off. Recommendations of technological solutions for decompaction of the root layer of the soil of the lawn space, which occur due to intense loads, are presented. It was revealed that the use of the studied water-soluble and instant fertilizers in the conditions of the south of Russia reduces the weediness of the lawn, increases its projective cover and the productivity of shoots of lawn grasses, and increases the breaking load. At the same time, the lawn coverings that are most aligned in height are noted. As a result, the quality and decorativeness of the lawn improve.

Abstract
The article describes issues of improving technologies for the cultivation of major agricultural crops, technical re-equipment of agricultural production particular processes, proposes new technologies, high-production technical means, methods of completing energy-rich units and ways to increase the competitiveness of crop production. The article proposes the program for the material and technical re-equipment of winter wheat production in the Krasnodar Krai. The problems of harvesting grain crops with combine harvesters are considered and the new threshing scheme by the “unwinnowed grain” method with harvesters, made in Canada, is proposed. The issues of using different varieties of wheat in terms of maturation are considered in order to increase the sowing time and further harvesting periods and, hence, reduce the number of sowing and harvesting equipment. The technology has been developed for the cultivation of winter wheat using new harvesting equipment and new methods of sowing wheat of different ripening periods. The transition to the proposed technology of winter wheat cultivation and harvesting locally in one of the Krasnodar Krai regions will lead to significant annual savings in labor costs. With the strict implementation of the technology, in particular, the optimal sowing and harvesting timing, using the new technology, the fields will be completely free of weeds over several years.

Published: January 2022

Abstract
Khanh Hoa Coastal area is considered the area with the most diverse coral reefs in the west of the East Sea. With the trend of increasing global temperature, the coral reefs here are affected, including the phenomenon of bleaching. This paper uses a Multi-scale Ultra-high Resolution Sea Surface Temperature (MUR SST) data source to evaluate the possible relationship between sea surface temperature and coral bleaching in the period 2010-2019 in Khanh Hoa coastal area is based on two parameters: Hot Spot (HS) and Degree Heating Months (DHM). Research results show that in the past 10 years, corals in Khanh Hoa coastal area may experience heat stress in 6 years, including 2010, 2013 and the years from 2016 to 2019. The phenomenon of heat stress starts to occur in May of each year, and the level of heat stress in 2010 was stronger than in other years. Within 6 years, there have been heat stress, coral bleaching events due to temperature only occurred in 2010; while in 2013, 2016, 2017, 2018 and 2019, corals suffered from heat stress in the watch level, meaning an increase in temperature is not yet capable of causing coral bleaching. The cause of coral bleaching in 2010 was the combined effect of the increase in sea surface temperature and the suppression of upwelling during the southwest monsoon.

Abstract
Arsenic contaminated groundwaters is a global environmental issue which cause serious problems for human health risks. 188 groundwater samples were collected in private wells of Lam Dong Province, a central highland area, Vietnam to investigate the health risks to the local people by using arsenic contaminated groundwater for drinking purpose. The result showed that the arsenic concentration is average of 14 μg/L and maximum of 500 μg/L. About 12% out of the total groundwater samples have arsenic concentration exceeded that value of 10 μg/L recommended for drinking water by World Health Organization (WHO, 2019). The health risk assessment showed that hazard quotient (HQ) value for adults was up to 60.6 with an average of 1.7 and about 14% of total samples show the HQ values greater than 1. The HQ value for children is average of 4.7 (maximum of 166.7) and about 23% of total groundwater samples show HQ > 1 for children. Cancer risk (CR) values were up to 27x10-4 (average of 8x10-4) for adults and 75x10-4 (average of 21x10-4) for children. About 26% and 29% of out of the total samples show CR value for adult and children greater than the CR (1×10-4) proposed by the USEPA. The result also indicated that the consumption of arsenic contaminated groundwater may seriously damage the human health. Therefore, groundwater in the area needs to be treated for arsenic removal before drinking to minimize the adverse effect on local communities’ health.
Acute and chronic toxicity of mixtures of bisphenol A and trace metals (Cd and Pb) to micro-crustacean, Daphnia magna
Authors: Nguyen V T , Huynh A T , Dao T S 
Published: January 2022

Abstract
The occurrence of plastic additives and their ecological impacts have attracted much attention in recent years globally. Among plastic additives, the trace metals (e.g., Cd, Pb) are widely used as color pigments and stabilizers, whereas bisphenol A (BPA) is added to enhance the desired physical characteristics of plastic products. However, these additives can easily leach out of plastic materials and enter the aquatic environment causing risks to aquatic ecosystems. Although the toxicity of a single additive on various aquatic organisms has been studied, the responses of zooplankton exposed to the mixed plastic additives have not been fully understood. Therefore, this study aims to evaluate the effects of the binary mixtures (BPA+Cd, BPA+Pb) and trinary mixture (BPA+Pb+Cd) at the metal concentrations of 5 µg/L and BPA level of 50 µg/ L on the life history traits and food feeding rate of the freshwater micro-crustacean, Daphnia magna. The results showed exposures to these mixtures for 24h could significantly enhance the food feeding rate of D. magna from 2.5 – 5.8 times higher than the control. The survival rate was decreased from 50 – 90% in the organisms exposed to these mixtures after 18 incubated days. We found a synergistic effect of BPA+Pb but an antagonistic effect of BPA+Pb+Cd on the survivorship of D. magna. Similarly, the organisms in the exposures delayed their maturity age and reduced their reproduction. The potent impact order of the mixtures on D. magna was BPA+Cd > BPA+Pb+Cd > BPA+Pb. Our results evidenced the adverse effects of plastic additive mixtures on aquatic organisms. Therefore, the use and disposal of plastic materials and plastic additives should be paid more attention to protect the environment, ecosystem, and human health. Moreover, our findings proved that the toxicity of multi-contaminants on organisms could be unpredictable even the toxicity of a single contaminant is known.
