Published: November 2023

The research has been conducted in the experimental greenhouses of Scientific Center of Vegetable and Industrial Crops, RA in 2020-2021. Bean varieties were grown without heating during the spring vegetation period. It has been empirically established that per all growing and development indices the best results have been recorded in the local bean varieties of Zepyur (control), Gohar, Ghapan variety-population and in the foreign variety White Ruler cultivated through potting and hill-drop technique. Throughout research activities it has been disclosed that in unheated greenhouse conditions (in the spring vegetation period) the application of pot planting method has been more feasible and effective than hill-drop planting (direct-seeded plants) technique, since the former technique promotes long-lasting fruiting of plants, development of a powerful root system, foliage improvement and, ultimately, a higher yield capacity (the yield surplus was 0.9-1.2 kg/m2).

Published: November 2023

The article presents the results of agroecological study of the common bean collection, not only under the conditions of the subtype of light chestnut soils of the Astrakhan region, but also worked out the mode of irrigation of this crop, inoculation of seeds with rhizotorphin on a drip irrigation method. The need for research was primarily due to the insufficient number of bean varieties ideally adapted to the specific climatic conditions of the region, which is associated with insufficient study of both the morphology and biology of the culture. As objects of study, a test culture of beans and the drug rhizotorfin were chosen. The study showed that when cultivating common beans under irrigated Astrakhan region in the subzone of light chestnut soils, it is advisable to carry out pre-sowing inoculation of seeds with rhizotorphin, which ensures a stable yield of common beans on drip irrigation, and also contributes to the accumulation of biological nitrogen. Thus, based on the data obtained, on drip irrigation in the subzone of light chestnut soils, it is economically feasible to sow in a wide-row method (0.70 m) with a seeding rate of 500,000 germinating seeds per hectare and carry out pre-sowing seed inoculation with rhizotorphin.

Authors: Maslennikova S.I. , Sarychev A.N. , Reznikova O.V.
Published: November 2023

The article discusses the results of studies on the study of modern released varieties of spring barley in the conditions of an agroforestry landscape and their response to various methods of basic tillage. It was found that in years with different climatic characteristics, there are differences in varieties in the duration of phenological phases. The longest vegetation was observed in the Bulat variety, and the shortest in the Prairie variety. The best results in terms of germination and preservation of plants were obtained in the variant with the Bulat variety, while in all varieties it was noted that these indicators were higher in the forested area than in the agrolandscape without forest belts. Analysis of the productivity of varieties showed that the studied varieties had different yields depending on the methods of tillage and the type of agricultural landscape. On the reclaimed territory and without protective plantings, the Bulat variety can be distinguished. The yield of this variety was the highest in all studied tillage options compared to other varieties. In the variant with flat-cut tillage to a depth of 0.25-0.27 m, it amounted to 2.63 t/ha under the conditions of the agricultural landscape without forest belts, and 2.89 t/ha under the protection of forest belts. Thus, it can be recommended for agricultural producers to cultivate the Bulat variety, and to carry out the main processing of light chestnut soil with a tool with flat-cutting working bodies to a depth of 0.25-0.27 m.

Published: November 2023

The article deals with potato protection systems, the use of multi-strain biopreparations with protective functions and chemical pesticides. Preparations were analyzed and selected, as well as a mycological analysis of the soil was carried out to determine the ecological and trophic groups of microscopic fungi, which in turn made it possible to select biological preparations and develop regulations for their use. Techniques aimed at reducing the use of chemical protection agents when growing potatoes in conditions on irrigated light chestnut soils have also been studied, and schemes for applying biological preparations that reduce the pesticide load on agricultural landscapes have been presented. Long-term studies on the use of biological products make it possible, in unstable natural and climatic conditions, not only to reduce the infectious background of pathogenic microflora, but also to increase the productivity of the culture.

Authors: Kataev M.Yu. , Lukyanov A.K. , Nabiullin V.V.
Published: November 2023

The article discusses a method for assessing the growth rate of plants, as a variant of understanding the ripening time and understanding the harvesting time of an agricultural crop. In most well-known software products, as a rule, they operate with averaged data on the field area, which is a very rough approximation, since fields can have different topography, water supply, soil types, etc., which affects the growth rate of plants. This article presents an approach to assessing the growth rate of an agricultural crop based on the dynamics of the NDVI vegetation index for each pixel of a satellite image. Multispectral images of the MSI Sentinel-2 device are taken as satellite data. The results of the assessment of the vegetation index and growth rate of agricultural crops, as well as the values of temperature, humidity and total precipitation for four months (May, June, July and August) are shown. The proposed results can be used in various farms to estimate the time of ripening and, accordingly, the harvesting of crops. Keywords: Sentinel-2 multispectral instrument, NDVI vegetation index, winter wheat, growth rate estimation.

Published: November 2023

Sorghum is one of the staple foods in the world's poorest regions, where food security is of the greatest concern. Sorghum is capable of growing even in the poorest soils, but it is very demanding on surface treatment. For drought-tolerant sorghum, the soil must be loose and breathable. The aim of the study was to select the means of mechanized tillage for growing sorghum and optimize its parameters. To obtain a crop, a new design of a universal disc-chisel harrow was developed. The harrow consists of two modules: disc and chisel. It allows you to perform various surface treatment operations: cultivating at a depth of 100 mm, loosening at a level of 200 mm and plowing at a level of 300 mm. The novelty of the structure is protected by a patent of the Russian Federation. A prototype was assembled and full-scale experiments were carried out. As a result of significant optimal values of the speed of the unit and an increase in the speed of the disks, the best quality of surface treatment is achieved.

Authors: Gazetdinov M.Kh. , Ibragimova R.M.
Published: November 2023

The financial stability of agricultural organizations is characterized by the provision of their own financial resources sufficient for stable economic and social development. In the state program “Development of agriculture and regulation of agricultural products, raw materials and food markets” in force until 2025, both in the country and in the Republic of Tatarstan, increasing the financial stability of agricultural producers is a priority goal. According to the results of the research of the author of this work, it has been established that the current liquidity ratio is a relatively acceptable single indicator of financial stability. At the end of 2021, 566 agricultural organizations have introduced production activities in the Republic of Tatarstan. Their share in the volumes of grain produced by all categories of farms was 74%, sugar beet – 87.5%, livestock and poultry – 75.3%, milk - 63.6%, eggs – 77.4%. The average coefficient of their current liquidity is 160%, which is significantly lower than the standard value. This indicator of financial stability depends on internal and external factors. Taking into account the leading role in external factors of state support, the purpose of this study was to study its effectiveness. The results showed that there is practically no connection between the level of financial stability and state support for agricultural organizations. In conclusion, it is proposed that part of the budget subsidies should be tied to the level of their profitability without subsidies as a stimulus to the economic efficiency of production.

Published: November 2023

The aim of our work was to determine the sensitivity of rabbits to the C-BSE pathogen in the first passage, to obtain a laboratory model on rabbits to study the C-BSE pathogen. The results of the experiments showed that with intracerebral infection of rabbits with the causative agent of classical spongiform encephalopathy of cows (C-BSE) they are 100% sensitive to the pathogen with an incubation period of 570 to 1842 days. The disease proceeds with the development of a clinical picture typical of prion diseases, the development of pathomorphological changes in the central nervous system in the form of vacuolization of neurons and neuropiles in various parts of the brain and massive deposition of prion protein PrPSc both in brain tissues and in peripheral lymphoid tissue (spleen). The laboratory model on rabbits is a highly sensitive model for studying the prion of bovine spongiform encephalopathy (C-BSE) and probably the causative agent of v-CJD.

Determination of the shelterbelts influence on the average productivity of agrophytocenoses based on geostatistical analysis of spatial data and the NDVI
Authors: Narozhnyaya Anastasiya , Solovyev Alexander , Polyakova Tatyana
Published: November 2023

Shelterbelts effect positively on the elements of the microclimate, the water regime of soils, the agronomic properties of the soil, soil fertility in the agricultural landscape. The assessment of the influence of the density of shelterbelts on the overall productivity of arable land is poorly studied. In this study, the methodology for assessing of such impact with using GIS technologies is suggested. We propose to use the Normalized Vegetation Index (NDVI), as a standardized index showing the relative biomass of vegetation, averaged for each working area within the studied region for working plots of arable land with an area of more than 25 hectares in the Belgorod oblast. Paired correlation analysis between the density of shelterbelts and arable land productivity showed the weak relationship (R2= 0.124), however, the classification of the density of shelterbelts with the interval of 0.5 km/km2 allowed us to reveal the linear regression dependence y = 0.0059x + 0.5195 (R2 = 0.989) of arable land productivity from the density of shelterbelts. Taking into account that many abiotic factors can affect the yield, we additionally proposed to carry out typing to identify areas of the same type in terms of the relief of the earth’s surface, climatic conditions and productivity. To do this, the spatial clustering (K-means algorithm) was proposed to use. It was revealed that the productivity of agrophytocenoses increases by 10% with the increasing of the density of shelterbelts by 2 times with an average slope steepness of up to 2°. In physical terms, the yield of winter wheat will increase by 0.28 t/ha. Soil-protective crop rotations are an additional factor in increasing the value of the NDVI index on slopes more than 2°.

Authors: Gafarov Gadir , Takhumova Oksana , Nikolaev Petr
Published: November 2023

Creating a frequency characteristic curve for bioelectrical impedance analysis involves analyzing electrical resistance (impedance) values at different frequencies. This curve is used to evaluate the electrical properties of biological tissues or fluids. In the article, the impedance of the intracellular environment was evaluated and frequency dependence was established based on the electrical circuit model of the biological system. Xc = f(f), Z = f(f), φ= f(f) tgδ= f(f), dependencies were created for different frequency values of the intracellular environment in the Matlab program through a series-connected RC circuit. Regression and general statistical analyzes were performed. The most appropriate frequency range was determined to evaluate the impedance of the intracellular environment. The correlation relationship of electrical and dielectric parameters of the intracellular environment was also taken into account. Purpose: The main goal of the research is the selection of the optimal frequency range for bioimpedance analysis. In particular, the selection of the most optimal frequency was carried out in the assessment of intracellular electrical activity. The frequency range is determined depending on the electrical and dielectric parameters of the cell. Materials and Methods: Using the Matlab program, the equivalent circuit model of the cell was assembled. Frequency dependence of electrical and dielectric parameters characterizing intracellular processes was performed by model-based measurements. Conclusion: According to the obtained value, regression and general statistical analyzes were performed for the dependencies Xc=f(f), Z=f(f), φ=f(f), tgδ=f(f). Based on analysis of variance (Analysis of Variance-ANOVA) of the output variables, statistical parameters were determined for each dependency.

Authors: Savin Egor , Akhmedov Asvar , Khoperskov Alexander
Published: November 2023

We investigated the operating conditions of excavator equipment, leading to unsteady dynamics of dust far from the pollution source. Wind transport of dust takes into account the non-uniform vertical wind profile. Diffusion movement is also determined by the inhomogeneous coefficient of turbulent diffusion with a nonmonotonic dependence on height. The Earth’s surface is given by a digital elevation model, which allows calculations for a specific area with complex topography. Vertical inhomogeneities of wind and turbulence significantly change the nature of the spatial distributions of dust particles. Our approach makes it possible to determine changes in the disperse composition of particles with distance from the dust source.

Authors: Seleznev Vladimir , Selezneva Aleksandra , Selezneva Kseniya
Published: November 2023

For the Volga River, studies of interannual changes in water discharges in the period 1958-2021 were carried out. Systematic hydrological observations were carried out at the Zhiguli hydroelectric complex on the border of the Middle and Lower Volga. 97% of the water runoff of the entire Volga is regulated in this section in the seasonal, weekly and daily range. It was found that the average water flow was 7704 m3/s. The amplitude of interannual fluctuations was 5270-10431 m3/s. Temporal changes in the average annual water discharges were characterized by cyclicity, including the change of low-water and high-water phases. From 1958-1975 a low-water phase was observed, from 1976-1996 - high-water and since 1997-2021 - again shallow. A comparison of the historical (1877-1955) and modern (1958-2021) periods showed that over 144 years, the average water flow of the Volga River has not changed much. However, as a result of the regulation of water flow in the period 1958-2021 the value of water discharges in high-water years decreased, while in low-water years it increased.

Drying agricultural products is a technological process that requires a large consumption of thermal energy and fuel-energy resources. The results of the conducted analysis showed that electric heating devices are often used to operate such a system, which are always expensive and not economically acceptable. In this paper, in order to reduce the traditional energy consumption for drying agricultural products, a combined device of solar dryer-water heater with heat accumulator is proposed and experiments were conducted in the meteorological climate of Karshi city. As a result of experimental studies shows the heat load compensation and energy efficiency of the solar water-air heating collector drying device with a heat accumulator in the “water + air” heating mode. The installation efficiency was found to be in the range of 0.66 - 0.72.
Cold wintering of coastal birds in the source and upper reaches of the Angara river: Changes in abundance and species structure in the conditions of a sharp climate warming
Authors: Mel’nikov Yuriy
Published: November 2023

Based on long-term research (1972-2023) and analysis of literature data, materials on the dynamics of the number and species structure of wintering shorebirds and waterfowl on cold wintering in the source and upper reaches of the Angara River (up to the town of Usolye-Sibirskoye) are presented. This is the largest cold wintering of coastal birds in Eastern Siberia – up to 55.0-60.0 thousand birds, the formation of which is due to very specific conditions of the upper reaches of the Angara River. This is the thermal refugium of the Upper Angara region, which ensures the accumulation of birds at the end of migration in more favorable areas of this region. It is divided into two sections: the first stretches from the source of the Angara River to the village of Taltsy, the second from the Irkutsk hydroelectric dam to the town of Usolye-Sibirskoye, and in warm winters slightly below it. On the basis of special works on the study of the dynamics of the number and species structure of birds, special methods have been developed: accounting on ice holes, accounting during the evening flight of birds to the lake Baikal (during cold periods) and accounting using a hovercraft (SVP) (during periods of severe climate warming). The basis of wintering birds is the Goldeneye Bucephala clangula (from 95.0% to 98.5% of their total species structure). However, the structure of secondary species can increase dramatically and we have noted new species that have never been found here before. The collected materials allow us to understand the reasons that determine the dynamics of the number and species structure of coastal birds in the “cold” wintering grounds of Inner Asia in the conditions of a sharp warming of the climate

The article presents the results of research on the possibilities of providing heat-cooling and electricity supply systems to autonomous consumers located far from centralized energy supply in the southern regions of Uzbekistan (Bukhara and Kashkadarya) based on renewable energy sources. In these regions, the average daily relative solar energy is 4.5 kWh/m2/day, the average wind speed is 5.5...8.5 m/s, the relative energy is 300...580 W/m2, and the underground low-potential temperature at a depth of 3...5 m, on average, is +10...+12oC. Analyzes of scientific research conducted on the development and reliability of trigeneration systems in the world are presented, and the possibilities of using these systems in our region are based. A combined solar-wind power plant, which is adapted to the climatic conditions of the southern regions of Uzbekistan, works efficiently in weak wind currents and high temperature regimes, and a complex energy system consisting of geothermal heat pumps that produce continuous heat and cold energy in different temperature regimes is offered. The proposed complex power plant allows for continuous and reliable energy supply to autonomous consumers located far from the centralized energy supply.

The sections of wells that have discovered oil-bearing deposits of the Bobrikian horizon, within the Aktanysh-Chishminsky trough in the northeast of the Tatarstan, are considered. In the terrigenous complex of the Bobrikian age, alternation of mudstones, siltstones, and sandstones is observed. According to the peculiarities of composition and porosity, mudstones and siltstones are classified as impermeable rocks, sandstone - as reservoir rocks. The study of sandy reservoirs showed that the rocks are characterized by a monomineral quartz composition, uniform oil saturation, fine-grained structure, massive texture. The porosity of sandstones is 15-20%. The pores are connected and form winding channels up to 0.1 mm in diameter. Sandstones form covers over the biogenic structures of the Tournaisian Stage, wedging out laterally and being replaced by dense siltstones. Good capacitive properties of the rock were acquired due to the leaching of calcite cement during the migration of water-oil fluids. Currently, sandstones contain oils with a predominance of light oil and medium paraffin fractions.

Published: November 2023

Graphene oxide/epoxy composite coatings have attracted much attention from researchers due to their excellent anti-corrosion properties. Graphene oxide as a two-dimensional nano-filler can enhance the overall properties of epoxy resin coatings. In the paper, models of graphene oxide/epoxy composite coatings with different permeation degrees are constructed respectively. The interfacial interaction between GO and epoxy resin and the adsorption properties of epoxy coating with metal are analyzed from an atomic perspective by molecular dynamics simulations. The results indicate that the interfacial adsorption effect of the epoxy coating on the protected metal is stronger than the interfacial bonding of GO on the epoxy resin matrix. Simulations of models with different degrees of permeation suggest that the permeation of the NaCl solution occupies the interfacial space and reduces the adhesion between the two interfaces.

Published: November 2023

The chitosan derivatives scale inhibitor CTS-AMPS was synthesized by using chitosan and 2-acrylamido-2-methylpropane sulfonic acid as raw materials and ammonium persulphate as initiator, and the structure of the product was determined by ATR-FTIR. The scale inhibition performance of CTS-AMPS for municipal water was tested. The results showed that when the concentration factor of municipal wastewater is 2.5 times and the dosage is 30 mg/L, the scale inhibition reached 76.6%. The results of SEM show that the scale inhibition performance of CTS-AMPS is mainly due to lattice distortion.

Published: November 2023

Against the backdrop of global warming, the changing area of Arctic sea ice is constantly shrinking, and the fluctuation of the Arctic sea ice area is the outcome of multiple factors. This paper mainly studies the volatility, periodicity, trend and related climate factors of Arctic sea ice area variation. It is found that the period of Arctic sea ice area variation T is equal to 3.468 years by establishing a sea ice area change model, and there is a strong negative correlation between the time series of the deseasonalized temperature and the sea ice area through the correlation analysis, with a Pearson coefficient of -0.711. In addition, the Bruun rule leads to the conclusion that for every 1cm increase in sea level, the coastline will retreat by 0.5- 1m, which indirectly indicates that without considering other conditions, the continental area will decrease as the sea ice area decreases. Finally, the conclusion obtained is that the CO2 level has the highest correlation degree by establishing a grey correlation degree model for each factor. Based on this, various measures are proposed to find solutions to the relevant factors and change existing policies to minimize the harm of the warming climate.

Published: November 2023

Pumped hydro energy storage (PHES) is one of the energy storage systems to solve intermittent renewable energy and support stable power generation of the grid. About 95% of installed capacity of the global energy storage system is contributed by PHES. Life cycle assessment (LCA) is used to analyse the environmental impact of PHES construction and operation phase in this study, and 1 MWh of electricity delivered from PHES to the power grid is set as the functional unit. The results show that the electricity power structure and electricity loss caused by the charging-discharging of PHES are the main environmental burden contributors, contributing 80 to 99% of the total environmental emissions. And environmental impacts during the construction phase is mainly due to the use of concrete, steel, and cement. In the future, as the proportion of renewable energy in the grid structure increases, the environmental impacts caused by PHES will decrease accordingly.
