Published: June 2022

Abstract
An assessment of oat varieties by yield and adaptability parameters based on the results of their testing in the conditions of the subtaiga of the Tyumen region for 2018-2020 provides in the article. A significant variation of conditions over the years of the test was revealed based on the value of the index of environmental conditions, as well as a significant interaction of genotype-environment based on the change in rank of varieties by yield during the years of their testing. The variety Talisman (3.95 tons/ha) was the best in terms of average yield, and the variety Tobolyak (85.5%) – in terms of yield potential. The variety Foma (4.05 t/ha) had the most yield under contrast conditions. The range of yield was significant for all varieties and was from 23.3% (Otrada) to 37.3% (Foma). High responsiveness to changing conditions was noted in the varieties Foma and Talisman, and low – in the varieties Megion, Otrada and Tobolyak. All varieties had low adaptability, the coefficient of which was at the level of one. The variety Talisman was recognized as the best in the conditions of the subtaiga in the Tyumen region based on the ranking of varieties in terms of their yield and main adaptability parameters.

Abstract
Growing in different ecological conditions, pumpkin varieties acquire new economic characteristics, which indicates agroecological differentiation of pumpkin. Under growing conditions in the Ararat Plain, we studied 8 portion varieties of pumpkin, which differed in the timing of the onset of phenophases, the timing of the receipt of products and yield indicators, and quality indicators of fruits. According to the growing season, the varieties were divided into early-ripening varieties - Syunik, Saporik and Veronez, mid-ripening - Volzhskaya gray 92, Children’s delicacy, Konfetka, Prikubanskaya and late-ripening - Gribovskaya winter. The yield data of variety samples were analyzed: the most productive were the Muscat varieties Saporik and Prikubanskaya with high taste qualities of fruits - 23.2±1.1 and 30.6±1.1 t/ha. Among the large-fruited pumpkins, varieties Detskaya delikatesnaya and Syunik stood out, which were distinguished by high palatability and yield - 25.3±1.0 and 23.0±1.4 t/ha, respectively. The varieties Saporik, Syunik, Detskaya delikatesnaya and Konfetka stood out for the high content of total carotenoids, in which this indicator was 16.05, 10.50, 15.22 and 18.25 mg/%, respectively.

Published: June 2022

Abstract
The world’s energy sector faces two major challenges: one is the rapid rise in the price of oil products, and the other is the increase in the amount of carbon dioxide emitted by industry into the atmosphere, leading to global warming. Developments in alternative energy sources, such as solar and hydrogen energy, are becoming increasingly relevant. In this regard, there has been a lot of interest in converting CO2 into useful products. Hydrogenation of carbon dioxide into useful energy resources and chemicals is becoming increasingly important as it is seen as a promising way to reclaim harmful CO2 as a by-product. The article considers modern technologies of hydrogen production and industrial conversion of carbon dioxide into useful products, and also describes the author’s natural method of catalytic conversion of carbon dioxide into useful green energy resources – hydrogen and hydrocarbons.

Published: June 2022

Abstract
Every year the problem of disposal and utilization of waste from livestock complexes is becoming more and more severe. Organic waste can significantly harm the environment if it is not properly treated and stored. Without proper processing of organic waste, they are objects of increased concentrations of pollutants, as well as a favorable environment for pathogenic organisms. Most of the participants of the livestock market pay little attention to this issue, economizing on places of disposal and utilization of organic and other wastes associated with livestock farms, as a result, in places of waste discharge contamination of soil resources, groundwater and located near water bodies occurs. To minimize the damage from such violations, it is necessary to monitor the surrounding areas of livestock farms. In this work an environmental assessment of the territories adjacent to the livestock farms located in Kaliningrad region was carried out.

Published: June 2022

Abstract
This paper shows the effect of various doses of a mixture of nanopowders of metals-microelements of iron and nickel (Fe + Ni) on the growth of corn, yield and its structure. Various doses of a mixture of Fe+Ni nanopowders were studied in the range of 0.5-2.0 g/t for corn ROSS 145 MB (grain hybrid). A mixture of iron and nickel nanopowders is effective in dressing corn before sowing. When using a dose of NP Fe + Ni 1.0 g/t, the height of plants in the phase of 5-6 leaves increased by 7.1%, in the flowering phase the leaf area increased by 18.4% higher than the control. It is shown that a mixture of Fe+Ni nanopowders 1.0 g/t increased the yield of green mass with cobs by 12.6%, cobs without a wrapper - by 14.3%, the weight of 10 cobs - by 185 g or 10.9% higher than the control. Under the influence of the optimal dose of nanopowders NP Fe + Ni 1.0 g/t in corn grain, the ash level increased by 0.18%, crude protein - by 1.4%, the amount of fat practically did not change. The content of vitamins has changed significantly, for example, vitamin C in the experiment is almost 2 times higher than the control, vitamin A - by 48%, vitamin E - lower than the control by 20%.

Abstract
The article discusses the research results on the internal electrical networks operation of two independent individual residential buildings with a 0.38 kV voltage three-phase electrical input energy. It is established that these electrical networks operation is characterized by a significant currents and voltages unbalance level, which leads to a quality standards violation and electrical energy additional losses increase. When using the computer program “ModulHous”, which algorithm is based on the developed calculation methods, the currents and voltages unbalance calculation was performed. With the use of the MATLAB graphics editor technology, the obtained changes visualization in the currents and voltages unbalance has been implemented. The obtained diagrams analysis made it possible to establish the unbalance power consumption level and its impact on the internal power supply efficiency of the individual residential buildings. A special balancing device is proposed that automatically minimizes unbalancing flows in the internal individual dwellings electrical network. The developed software made it possible to establish the using balancing devices efficiency to improve the quality and reduce electrical energy additional losses in the considered electric networks of individual residential buildings.

Authors: Blinov V l , Deryabin G A 
Published: June 2022

Abstract
This paper considers the method to estimate the technical condition of gas turbine power for natural gas transportation, using machine learning methods. Source data was used to archive gas-dynamic parameters from the automatic control system of the gas turbine. The method is based on changing the enthalpy of the natural gas before and after the centrifugal gas compressor is used for creating a dataset with measured parameters and power from the gas turbine. The actual power is determined from the line of modes for a certain period. The software is implemented using Python and the Scikit-learn library is used to create machine learning models. A mean average percentile error is chosen as the model quality criterion. In this paper, different sets of feature parameters and sample sizes are researched by the quality of the prediction machine learning models. Recommendations on the use of models are given. It has been established that the approach is not applicable for predicting future technical condition without the presence of data on a similar technical condition in the training sample. It is recommended to use the described approach to determine the technical condition in a period of operation in the past.

Published: June 2022

Abstract
The agrochemical properties of the soil make it possible to assess the level of its fertility. The search for new forage crops is an urgent task in agriculture. Under the conditions of a high anthropogenic impact of man on soils through the introduction of mineral fertilizers and pesticides, the use of biological products in the cultivation of field crops is a solution to most environmental problems in the soil. This article presents materials on the study of the influence of various systems of basic soil cultivation and biological products on the agrochemical properties of the soil, as well as the productivity of field crops. The content of organic matter, the content of mobile phosphorus, the content of exchangeable potassium, hydrolytic and exchangeable acidity, and the amount of absorbed bases were determined. The yield of green mass and the yield of feed units of new promising crops for the soil and climatic conditions of the Yaroslavl region - soybeans, amaranth and buckwheat - were assessed. The studies were carried out under the conditions of a field stationary three-factor experiment on sod-podzolic medium loamy gley soil of the experimental field of the Yaroslavl State Agricultural Academy. The positive role of using Baikal EM-1 in the system of moldboard processing in buckwheat crops is shown. In this case, there is an improvement in most agrochemical indicators of fertility and it is possible to obtain maximum productivity.

Published: June 2022

Abstract
In connection with the intensive development of animal husbandry at the present stage and the need to strengthen the forage base, an urgent problem arose to expand the areas of estuary irrigation systems and increase the productivity of flooded hayfields. These reclaimed lands of the Caspian lowland currently have low efficiency due to the deterioration of the technical condition of engineering structures and the degradation of hay grass. For arid conditions, a technological regulation has been developed to improve the designs of estuary irrigation systems, which makes it possible to ensure a clear and complete implementation of measures, taking into account local characteristics. The proposed regulation defines the procedure for organizing, methodology and technology of work on assessing and forecasting the ecological and reclamation state of lands and phytocenoses on estuary irrigation systems in relation to the conditions of the Republic of Kalmykia. A regional system for monitoring the ecological and reclamation state of lands and phytocenoses on estuaries has been developed, which allows for regular monitoring and timely adoption of comprehensive measures to improve the environmental situation in estuary irrigation systems. Technological regulations for elements of zonal technologies for surface and radical improvement of engineering estuaries, as well as regulations for the radical improvement of saline and solonetzic estuary lands using chemical amelioration have been developed. The introduction of these technologies makes it possible to increase the productivity of firth hayfields up to 5.0-8.0 t/ha, which is 2.5-6 times higher compared to the current level.

Abstract
In the conditions of spring unheated greenhouses in the Rostov region on improved natural soils, the influence of the methods of tying tomato plants of various types of growth on the processes of crop formation and its quality indicators was assessed. The issues of the influence of methods of tying plants on the crop, its marketability, the share of early harvest and the average weight of the fruit are considered. It has been established that, on average, indeterminate hybrids, although they do not have a high total yield and the share of early production, however, have maximum marketability and average fruit weight. In determinant hybrids, the optimal combination of yield and quality was obtained from the Primadonna F1 hybrid, for semi-determinant hybrids, for the Rozovyy nosik F1 hybrid tied to twine, and for indeterminate hybrids, for the Makhitos F1 hybrid, also tied to twine with a garter gun with a red ribbon for partial mechanization of the process.
Improved modelling of magnetic splitting in a chrome alum below 300 mK
Authors: Gunderson C , Miller F , Chui T , Paine C , Prouve T , Holmes W 
Published: June 2022

AbstractChrome-Caesium Alum (CCA) is a paramagnetic salt that can be used to achieve ultra-low temperature refrigeration through adiabatic demagnetization. Cooling capacity measurements of CCA show a significant reduction below the isolated paramagnetic spin model for temperatures below 100 mK. A more complete understanding of the thermodynamic properties of CCA could improve model accuracy, vital for meeting cooling requirements at subKelvin temperatures. Modelling effort was undertaken to understand the physical origin of this reduction in heat and refrigeration capacity, and measurements from two separate CCA salt pills between 50 mK and 300 mK were used for model validation. Both the model and the experimental design and results are discussed in this work. The model uses exact eigenvalues for the Cr3+ions from the spin Hamiltonian. Two interactions of interest are the zero-field splitting and hyperfine splitting, as these are not standard in presently used models.We found that, though hyperfine interactions were not significant at temperatures above 50 mK, the inclusion of the zero-field splitting interaction resulted in qualitative agreement with the data. We optimized this model using a nonlinear least square regression to find the best fit to the two experimental data sets with two independent fitting parameters. Measured data at 50 mK still show a significant reduction below the fitted model prediction. Conductance measurements and thermal relaxation times were used to characterize addenda heat capacity and entropy loss due to non-adiabatic effects, which were not found to be significant. Accordingly, cooling capacity reduction below 50 mK cannot be accounted for by these effects. CCA is in the same chemical family as Chrome-Potassium Alum (CPA) which used widely in adiabatic demagnetization refrigerators. Thus, this modelling work described here is applicable to CPA. New measurements are planned to understand if the remaining discrepancy between the model and data is a systematic effect or a more fundamental feature of the salt.
