Authors: Osadchyi V V , Yeremieiev V S 
Published: July 2022

Abstract
An algorithm for processing the results of monitoring the dynamics of ornithocomplexes on the territory of wind farms using statistical methods is proposed. The solution of the most frequently encountered problems in the analysis of bird migration in the wind farm zone is considered: 1) An algorithm for the primary statistical processing of information on the number of birds of various species, flight altitude and the time of their stay in the zone of interaction with turbines during monitoring has been developed in two ways: a method of route census and observations in accordance with the recommendations of the Scottish Natural Heritage Foundation. 2) The features of the application of correlation and regression analysis have been considered, which allow determining the dependence of the number of birds on a number of factors using the Student, Pearson and Fisher criteria in the presence of strong noise interference. 3) An algorithm of statistical analysis is proposed using a trend approach based on the Student, Irwin, Durbin - Watson, Pearson and Fisher criteria. The considered statistical methods were tested on the results of migratory bird census on the territory of the Prymorsk-1 wind farm located on the coast of the Sea of Azov, which were obtained by a group of researchers led by V Siokhin and P Gorlov.

Abstract
Forest cover is an important component of the landscape and is responsible for the conservation of other components. Forests of the Podolian Upland are distinguished by a high natural resource potential and a significant risk of manifestation of unfavorable natural processes. The aim of our research is to study the forest cover of Podilski Tovtry and analyze the dynamics of its changes for the period from 1880 to the present. Forestry nature management in Tovtry is second only to agriculture in terms of the area of occupied land. Forests of the reef zone and adjacent territories within the Ternopil oblast are part of the Ternopil forestry enterprise and the Medobory Nature Reserve. Within the study area, forests of a relatively large area are confined to the summit surface and slopes of the main ridge. Our research has established that in the period from 1880 to 1930, there was a significant decrease in forest cover practically throughout the entire study area, which is associated with both the need for firewood and agrarian overpopulation and the desire to expand the arable land. A direct relationship was found between the decrease in forest cover and the approach to villages and hamlets. After the Second World War and until the present, there have been no significant changes in forest cover. In some areas, even an increase in forested areas was found. Active forest expansion was observed at the beginning of the two thousandth years amid a decline in agricultural production.

Abstract
The environment plays an important role in shaping the living conditions of local communities, and the state of the environment determines the opportunities for achieving the goals of sustainable development. The purpose of the article is to provide further development of the conceptual foundations of the mechanism of management of enterprise interaction with environment. The authors formed an approach to structuring the mechanism of management of enterprise interaction with environment, considering economic, environmental, and adaptive components. For practical approbation of individual components of the proposed mechanism in a part of the instrumental block the ways of decreasing the negative impact of the enterprise on level of pollution of the atmosphere as of a component of environment were considered. The constructed correlation and regression model for determining the impact of individual pollutant emissions on the overall state of air pollution formed a basis for identification of two most significant types of emissions (carbon monoxide emissions and emissions of non-methane volatile organic compounds). Based on the analysis of ME “Zhytomyrvodokanal” data, whose activities are related to the waste generation and management and which, at the same time, provides environmental services, the measures were proposed to decrease the corresponding emissions from the enterprise activities.
The use of bischofite in the gas industry as an inhibitor of hydrate formation
Authors: Dmytrenko V I , Zezekalo I G , Vynnykov Yu L 
Published: July 2022

Abstract
The article considers the possibility of using natural, environmentally friendly, cheap raw materials as the basis of a complex inhibitor of hydration and corrosion. It is proposed to use bischofite solutions with mass fraction of 24% MgCl2 as a carrier of a complex inhibitor. A set of laboratory studies was carried out in order to eliminate the main shortcomings of bischofite solution. Such disadvantages are that highly concentrated solutions of bischofite, untreated from sulfate ions and iron compounds, without a corrosion inhibitor cause corrosion of equipment and salt deposits. According to the results of laboratory studies, the composition of a complex inhibitor of hydroformation and corrosion based on bischofite was proposed. Based on the results of laboratory studies, suitable reagents were selected for preparing a bischofite solution for use in the processes of production and preparation of gas for transport, and the mechanisms of reagents action were proposed. The results of industrial tests show the effectiveness of a new complex inhibitor. The achieved properties of the complex inhibitor have led to the improvement of technical, economic and environmental performance of gas production enterprises of Ukraine.
Statistical evaluation of fuel values
Authors: Walter A , Kubica S , Rocco V 
Published: July 2022

Abstract
Aviation emissions, domestic and international, account for approximately 2 % of total global CO2 emissions. Fuel consumption for a given route, excluding other factors such as wind, depends largely on the weight of the aircraft. To minimise fuel consumption, it is often most economical to carry only the minimum weight required for the sector. Within the framework of a dissertation, possibilities to reduce the final reserve fuel and thus the amount of fuel required are being researched and evaluated. This paper shows part of the results, as reliability and accuracy of flight planning and actual operations are a necessary basis for a possible reduction. The level of safety in aviation must always be taken into account. To prove this, fuel values are recorded and statistically evaluated, based on real flight and fuel data provided. Analysis, systematization and generalization were used to conduct the study. As a statistical background, extensive fuel data of an airline from a period of about five years were examined. The focus of this paper is on the results for taxi and trip fuel. The result shows that the current requirements for flight planning and the subsequent execution of flights are very reliable and highly accurate today. The results of the study can be used as a basis for a performance-based approach to reduce the final reserve fuel while maintaining the necessary safety level. Reducing the final reserve has a significant impact on reducing overall fuel consumption and emissions. Further research and studies are needed to determine performance indicators.

Published: July 2022

Abstract
Forecasting of the demand for energy resources is a very important scientific area when determining adequacy of energy resources in the country, compiling the country’s energy balance, determining need for import of some energy resources for the country’s economy for types of economic activity (TEA) and regions. The pace of development and proportions in the country’s and the region’s economy may affect their levels of energy consumption, and the latter determine the extent of energy industry’s impact on the environment, i.e. these indicators are interdependent. The relevance of the work is related to creation of a mathematical model and tools for forecasting the demand for energy resources and determining the amount of emissions of harmful substances into the atmosphere as a result of fossil fuels combustion. The methods and tools for forecasting the demand for energy resources for various types of economic activity or regions take into account the following factors: impact of changes in the structure of the economy on fuel and energy consumption as well as on technological re-equipment of industries that together form the overall energy saving capacity and structures of electricity production sources and heat energy supply sources to ensure their production. The authors propose a three-level model for forecasting the demand for energy resources (electricity, heat, fuel in total and its types: coal, natural gas and other fuels). This model uses a double agreement of forecasts: between the third (types of economic activity in regions), the second (regions) levels, and the subsequent agreement with the top (country) level. The calculations performed using this model demonstrate the feasibility of this approach. This model was tested on retrospective data with an error of less than 5%. Calculations under this model show a forecast of savings of 8.7 million tons of coal by 2040 due to structural and technological changes (2.272 million tons and 6.428 million tons, respectively). Reduction of coal consumption will reduce emissions of pollutants into the atmosphere (thousand tons): nitrogen oxides – 19.671; sulfur oxides – 295.06; carbon monoxide – 393.414; solid dispersed particles – 104.255; carbon dioxide – 5271.75.
Influence of organic and inorganic precipitators on the efficiency of surfactants extraction from wastewater by flotation
Authors: Khromysheva O O , Yakoviichuk O V 
Published: July 2022

Abstract
The chemical structure of surfactants causes their accumulation on the surface of water sources and leads to the formation of stable foam, which prevents the access of oxygen to the water and leads to the death of hydrobionts and deterioration in water quality. Therefore, the extraction of surfactants from wastewater is an urgent task. Increase the efficiency of flotation extraction of cationic surfactants, namely hexadecyl pyridinium chloride [C

The thermodynamic analysis of the process of formation of sublates allows determining the optimal length of the hydrocarbon radical of the precipitator. It is established that the extraction of the studied cationic surfactants should be extracted from water solutions and wastewater by the method of precipitation flotation using organic and inorganic precipitators. The presence of electrolytes and an increase in temperature leads to an increase in the degree of extraction hexadecyl pyridinium alkyl sulphonates sublates.
Response of earthworms to changes in the aggregate structure of floodplain soils
Authors: Tutova G F , Zhukov O V , Kunakh O M , Zhukova Y O 
Published: July 2022

Abstract
Earthworms are actively involved in the transformation of organic matter and in the formation of water-resistant soil aggregate structure. In the short time perspective earthworms are a factor that affects soil properties. However, other factors also influence soil properties and it is these factors that determine the total level of earthworm abundance and patterns of their spatial distribution. In urban park environments, the recreation load is an additional factor. The recreational load significantly affects the physical properties of the soil. An aggregate soil structure regulates the ratio of solid, liquid, and gaseous soil fractions and thus determines the living conditions of soil animals. Purpose/objective. The study tested the hypothesis about the influence of the aggregate structure of soil on the spatial distribution of earthworms under recreational load conditions. Methodology. Geostatistical methods and evaluation of animal response models to environmental factors. Results/findings. The aggregate structure of the soil is an important factor that affects the spatial patterns of earthworms under recreational load conditions. Earthworms prefer sites with a predominance of meso-aggregates. A recreational load leads to an increase in the proportion of macro- and micro-aggregates, which negatively affects the living conditions of earthworms. Conclusions. The processes of mutual influence of earthworms and soil aggregate structure have different temporal scales: earthworms influence soil structure in the time range of a few days or weeks, and aggregate structure influences in the time range of a few months or years.

Abstract
To estimate possible changes for some economical branches in South Ukraine which use the nature resources, three scenarios of climate changes were reviewed: increase of temperature and increase of precipitation; increase of temperature and decrease of precipitation; decrease of temperature and increase of precipitation. Impact on the Azov Sea ecosystems under these three scenarios was considered in respect of changes in salinity and temperature of water that consequently effects on ichthyofauna and fish industry. Trends of fish suffocation are also described. Agricultural risks induced by pests (on an example of the locust) under extreme high temperatures in a spring-summer season were discussed, with identification of possible distribution sites of the pest.

Published: July 2022

Abstract
Based on the studies in the period of 2010-2021, there was obtained some information on the behavior of bats and their species composition at the Zaporizhia wind park in the Zaporizhia Region, Ukraine. In the study area, there was established the presence of 10 species of bats belonging to 7 genera. The most complete results were obtained in 2019, when 4 field research methods were used, 28 expedition trips were carried out and 4177 bat signals were recorded. In total, the information on 43938 bat signals was collected in 2010-2021. The total operating time of the ultrasonic detectors was 4565 hours. There were calculated indices of the voice activity of bats for three research methods by seasons, different functional zones and phases of the annual cycle of animals. Surveys on transects with the geo-position of each recorded signal made it possible to characterize the distribution of bats over the territory of the wind farm, and the use of the Kernel Density tool allowed to differentiate the wind farm site of the Zaporizhia wind park into the zones that are conditionally safe for bats and high-risk zones. There have been determined the periods of the year and time periods of night activity, in which it is advisable to use measures to minimize the negative impact. Using international and own experience, there have been proposed methods for repelling bats away from the wind turbines.
Lake Biwa Canal at Kyoto Japan: sustainable development and revitalization
Authors: Shevtsova G V , Parkhomchuk M S 
Published: July 2022

Abstract
Lake Biwa Canal (engineer Tanabe Sakuro) connects Lake Biwa and Kyoto. It was built in the end of the 19th c. in order to revive Kyoto, which decayed after the transfer of the capital to Edo (Tokyo) in 1868 and served to supply Kyoto with drinking and industrial water, as well as for cargo transportation. The aim of the work is to determine the historical periods of Lake Biwa Canal’s existence and to highlight its significance for ensuring the sustainable development of Kyoto. The research was conducted at Kyoto mainly with field studies and interview methods. As a result, three historical periods of the Lake Biwa Canal existence were identified. In the first period (1885-1951), the canal combined water supply, transportation and landscape-shaping functions and was fundamental to the sustainable development of Kyoto. In the second period (1951-1990th), the transport role of the canal became unclaimed, and its role in sustainable development of the city significantly decreased. In the third period (since 1990th), the canal was designated as National Historic Site, and a campaign of its revitalization began. The Canal acquired touristic and educational functions and increased its role in the sustainable development of Kyoto. Thus, at the time of its construction, the Lake Biwa Canal was the main driving force that saved Kyoto from decline. Now, we can talk about the opposite process, when Kyoto City supports the sustainable development of the Canal.
Reconsidering the concept of sustainability: personal adaptability dynamics as predictor of positive change
Authors: Lushyn P V , Sukhenko Y V 
Published: July 2022

Abstract
The article deals with the attempt to reconstruct the concept of sustainable development in the context of the COVID-19 pandemic. The literature review supported the idea that the studies devoted to the features of sustainability in social systems are extremely fragmentary. The authors provided a holistic vision of the process of sustainable development in terms of a dialectical self-organization of open living systems. To accomplish this goal, a number of studies have been conducted at different stages of the COVID-19 pandemic. The findings confirmed a strong relationship between the psychological and social level of adaptation (as a manifestation of the adaptability/sustainability of the individual) to the conditions of the pandemic. This helps considering indicators of psychological stability as a predictor of social sustainability. The prospect of the further research consists in the reinterpretation of the current world in terms of a rhythmic, emergent, hybrid and innovative (REHI-world) self-organization of open living systems.

Authors: Wang Yuanjun , Wang Fazhan , Wang Yixuan 
Published: July 2022

Abstract
Based on finite element method (FEM) and the plasticity theory, a numerical model is built to simulate the hot isostatic pressing (HIP) process of W-Cu powders, and the densification law of the compact in the process is analysed. The cross-experiment method is used to formulate an orthogonal optimization plan for the insulation temperature, the holding pressure and the insulation holding time. The contour map diagram of the relative density in the temperature and pressure plane is established, and the optimal parameter scheme is proposed by simulation results. Experiments are carried out under the best HIP scheme. Comparison of experimental results with simulation results indicates that the numerical model is accurate. The results indicate that the densification process of the compact is from the edge to the centre. The optimal hot isostatic pressing parameter scheme obtained by simulation is 950 °C/110 MPa/2 h, and the overall relative density of the compact can reach more than 96% under this scheme. Under optimal scheme, the maximum error between the simulation results and the test results of the relative density is 1.28%, whereas the average error is about 0.3%.
On the choice of relativistic wave equation for the particle having spin s = 3/2
Authors: Simulik V M , Vyikon I I 
Published: July 2022

Abstract
Relativistic wave equation of motion without redundant components for the particle having spin 3/2 has been considered. In order to show the newness a comparison with the known equations for the spin s = 3/2 field is given. Therefore, the brief review of the relativistic wave equations for the particle with spin s = 3/2 is suggested. In our equation the wave function for the particle-antiparticle doublet contains only 8 components. The consideration is carried out both at the level of relativistic quantum mechanics and at the level of local field theory. The extended Foldy–Wouthuysen transformation, which gives the operator link between these two levels is suggested.
Artificial neural network-based path integral simulations of hydrogen isotope diffusion in palladium
Authors: Kimizuka Hajime , Thomsen Bo , Shiga Motoyuki 
Published: July 2022

Abstract
The contribution of nuclear quantum effects (NQEs) to the kinetics and dynamics of interstitial H isotopes in face-centered cubic Pd was intensively investigated using several path-integral techniques, along with a newly developed machine-learning interatomic potential based on artificial neural networks for Pd–H alloys. The diffusion coefficients (D) of protium, deuterium, and tritium in Pd were predicted over a wide temperature range (50–1500 K) based on quantum transition-state theory (QTST) combined with path-integral molecular-dynamics simulations. The importance of NQEs even at high temperatures was illustrated in terms of the characteristic temperature dependence of the activation free energies for H-isotope migration in Pd. This illuminates the overall picture of anomalous D crossovers among the three H isotopes in Pd. In addition, the D of protium in Pd was directly computed using two approximate quantum-dynamics methods based on Feynman’s path-integral theory, i.e. centroid molecular dynamics (CMD) and ring-polymer molecular dynamics (RPMD), in the temperature range 370–1500 K. The D values obtained from the CMD and RPMD simulations were very similar and agreed better with the reported experimental values than the QTST results in this temperature range. Our machine learning-based path-integral calculations elucidate the underlying quantum nature of the ‘reversed S’-type nonlinear behavior of D for the three H isotopes in Pd on the Arrhenius plots.
