To analyze the peculiarities of height differentiation of valley-river landscapes and to study their current structure taking a model region as an example – a plain territory of the Right-bank Ukraine.\u0000\u0000Methods. The study is based on the ideas of F. M. Milkov on anthropogenic landscapes and their vertical (height) differentiation. In the process of research the constructive-scientific landscape approach and the principles of complexity and natural-anthropogenic combination were used. The main research methods, in addition to field, are methods of theoretical generalization, historical and landscape, the leading factor, zoning, modeling, analogy and more.\u0000\u0000Scientific novelty. The main focus of scientists is only on the impact of vertical zonation on mountain landscapes. Height differentiation of valley-river landscapes has not been given due attention. This is especially true of river valley landscapes that have been transformed as a result of economic activity.\u0000\u0000Practical value. Previous experience in the optimization of anthropogenic landscapes shows that taking into account their height differentiation is a necessary condition for the development of various projects and schemes of environmental management. Given the growing anthropogenic pressure on the environment, such studies will help to better understand the course of negative man-made processes and contribute to the optimization, conservation and protection of modern valley and river landscapes. In the long run, this may be the basis for similar research in river valleys around the world.\u0000\u0000Research results. The development of height differentiation within the boundaries of valley-river landscapes of the Right-bank Ukraine was considered based on the earlier experience. 2 height-landscape levels (“young” accumulative and “typical” accumulative-denudation) and 4 tiers were singled out in river valleys. Bridges, dams, causeways, derivative HES, “water” mills, anthropogenic islands, ponds of a riverbed type or meliorative canals – all these are typical for a lower tier of a “young” accumulative height-landscape level. A middle tier is represented with water-economic and agricultural landscapes. An upper tier is formed with residential and mining-industrial landscapes. In river valleys a “typical” accumulative-denudation height-landscape level has one lower tier which is formed with two natural types of localities: sloping and canyon-like. This tier is characterized with a good preservation (up to 35%) of natural landscapes. Anthropogenic landscapes are represented mainly with forest-cultural, residential, agricultural and road landscape complexes. The conclusion has been made that with further anthropogenization of river valleys it is expedient to make designs of anthropogenic landscapes, distributing them on height-landscape teirs evenly and thoughfully.

Air pollution is one of the biggest modern ecological problem, which aggravates with process of urbanization, industrial development, increasing number of vehicles, etc. So that, the article is devoted to the study the of air pollution in the largest cities of the Volyn region: Lutsk, Kowel, Novovolynsk and Volodymyr-Volynskyi. The purpose of the article is to estimate state and quality of the air in the largest cities of the Volyn region, discover the main sources of air pollution, characterize the effects of pollution on people health and environment, propose measures for solving this problem.\u0000\u0000Review of previous publications and studies. State of the air pollution in the urban areas of the Volyn region became the subject of scientific interest of many scientists. Hulai L. D., Karaim O. A. and Syniuk, A. Yu. researched ecological state of air basin and structure of sources of air pollution in the Novovolynsk City. Panasiuk M. V. and Hulai L. D. analyzed air quality in the Kovel district and Kovel City. Problems of air pollution were investigated in the studies of Kiptenko Ye. M., Kozlenko T. V. and Molchak Ya. O., Fesiuk V. O., Kartava O. F. Moreover, Poruchynska, I. V. in her publication explored ways of reducing air pollution by vehicle in the Volyn region.\u0000\u0000Methods. The most common methods in the research were analysis and synthesis, correlations and regressions, generalization and comparison. Moreover, to study the quality of air basin in the largest urban area – Lutsk City, the authors calculated index of air pollution.\u0000\u0000Results. The study defined that the main source of air pollution in the urban systems are automobiles, which produce into the atmosphere 85-95 % of all emissions. Furthermore, stationary sources such as industrial enterprises and utility companies also pollute air basin of cities with hazardous substances. However, the amount of pollutants from these sources in the Lutsk City and Volodymyr-Volynskyi City slowly decreases. The authors researched that the air basin in Lutsk City is exposed to the greatest anthropogenic loading. According to the calculation of the air pollution index, city’s air basin belongs to the quality class «polluted air». Consequences of air pollution are quite different and have impact on environment and economic complex. Besides, poor air quality can cause different diseases. To solve this problem the authors propose to reconstruct and modernize enterprises’ treatment systems, to increase the number of environmental friendly public transport, to increase the areas with greenery, to introduce green logistics in transportation. The authors concluded that air basin in the most urbanized areas of the Volyn region is quite polluted, which caused by using vehicles and functioning of manufacture.

The gas saturation coefficient is one of the most important parameters for calculating gas reserves. The parameter can be determined by laboratory petrophysical methods applying the residual water saturation coefficient. The latter, in turn, is determined by direct or indirect methods. The direct method is used extremely rarely, while indirect methods are very common - primarily the methods of a semipermeable membrane and centrifugation. The first method is considered the most reliable.\u0000\u0000Formulation of the problem. When applying the semi-permeable membrane method, the issue of setting the maximum displacement pressure is the key factor that determines the result, as it determines the value of the residual water saturation, and, consequently, the value of the gas saturation coefficient of the reservoir. There are numerous cases when the results of laboratory studies of residual water, and hence the gas saturation coefficient, are clearly discordant with the whole set of geophysical and geological data. This problem is possibly caused by the wrong choice of the laboratory research modes, and specifically, the maximum pressure that is created in the course of the experiment.\u0000\u0000The research objective is to analyze the ways of setting the maximum water displacement pressures during the experiment in terms of the most reasonable, basic method of a semipermeable membrane; to evaluate their applicability taking into account the best practices and propose their optimal combination for practical work.\u0000\u0000Previous research. The paper considers various approaches to setting the maximum pressure, including an attempt to model the process of deposit formation, achieving irreducible water saturation, an express method using a centrifuge, determining water-holding capacity, limiting pressures by the size of filter pores, and calculating pressures on the basis of the deposit height.\u0000\u0000Main material. Two approaches have been distinguished from the considered ones: calculation of the maximum pressure on the basis of the deposit height and calculation on the basis of the maximum pore radius, at which a meniscus can be formed. It is shown that it is rational to combine these two approaches into one, which will allow obtaining more reliable values of the residual water saturation, and hence the gas saturation coefficient. The ultimate maximum displacement pressure for the semi-permeable membrane method, which should be created during the experiment, has been determined. The limiting height of the deposit has also been determined. Any calculation above this parameter does not make sense. The discrepancies between theoretical calculations and actually observed heights of capillary rise and the influence of the layered structure of the reservoir have also been considered. The area of possible practical application of the method has been determined.

IMM are deposited in a main ore bed, ore crusts and scattered in the wall rocks. It is synchronously sedimented with deep-water deposits of the lower bathyal. The оre bed is composited of concretionary, sinter, brecciated, earthy and sooty aggregates. Concretionary morphotypes have concentric-zonal structure, which is formed by shells with different mineral composition and structural features. Crystalline secretions are observed in the nucleus. The ore substance is represented by X-ray amorphous compounds of iron and manganese hydroxides, among which are minerals of hydrothermal (pyrolusite, psilomelan, todoroquite and bersenite) and hydrogenic (vernadite, buserite) origin. Shells often have columnar, dendrіtic and colomorphic structures typical of hydrothermal formations. Differentiation of mineralization by mineral composition causes significant fluctuations in metal contents in ore aggregates (from 3 to 11.5% of Fe oxides and from 2 to 10% of Mn) and host rocks (from 1.4 to 11.5% of Fe oxides and from 0.12 to 12% Mn). This confirms the endogenous origin of ore-bearing fluids. On the diagram of the ratios of the main components of iron-manganese formations of different zones of modern oceans by E. Bonatti, the geochemical composition of the ore mineralization of the Nad’yamne variegated horizon falls into the fields of both hydrothermal and hydrothermal-hydrogen origin. Mineralogical and geochemical features of ore mineralization indicate that the main source of metals on the seabed were hydrothermal vents.

The base of the Cenozoic deposits of Eastern Ukraine was chosen as an indicator surface reflecting both those and other movements. Its initial orientation is horizontal. Deviations from the horizontal reflect the direction and amplitude of deformations. The morphology of this surface was depicted by isolines with a vertical step of 20 m.

On the territory of the Dnieper-Donetsk depression, different models of structure of salt stock zones were found. The most promising for the search for hydrocarbon deposits are areas with satellite blocks near the underground salt stock.

The research used scientific and methodological foundations of natural-agricultural zoning of the territory of Ukraine, the allocation of taxonomic units of zoning and their main characteristics.\u0000\u0000Results of work. The scientific novelty of the obtained results concerns the improvement of ecological and economic management of land resources of agricultural enterprises in the conditions of zoning, taking into account the potential of agricultural areas.\u0000\u0000Economic and ecological management of land resources of agricultural enterprises should be considered as an activity in agricultural production aimed at providing the population with food and other sectors of the national economy with raw materials at the optimal level of investment in resources and their maximum return in compliance with environmental goals and programs.\u0000\u0000Agricultural zoning as a branch in the agricultural sector of the economy is highlighted, its component structure is revealed. The agrarian zone includes homogeneous land massifs with the corresponding production potential and level of ecological and anthropogenic loading and allows public administration bodies to be defined with potential possibilities of production activity of the agrarian enterprises. Within the Sumy region, four agricultural zones were identified, and in the Kharkiv region, three. Depending on the affiliation of land use to the agrarian zone, the agricultural enterprise receives information on zoning crops most suitable for cultivation on its territory, types of crop rotations, technological measures for land use and protection, restrictions on growing certain crops. Economic indicators of enterprise development, such as specialization, concentration and integration of production, with skillful application will help increase the efficiency of land use. Socio-economic classification features of agricultural zoning will determine the level of labor efficiency and the integration of labor. To economically justify the coefficients of the optimal ratio of land using a zonal approach and to take into account the area of eroded, unproductive and contaminated land ","PeriodicalId":52802,"journal":{"name":"Visnik Kharkivs''kogo natsional''nogouniversitetu imeni VN Karazina Seriia Radiofizika ta elektronika","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78507017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Post-communist planning in Ukraine was essentially transformed over the last years with new approaches, instruments and practices changing the very idea of planning at the local level. As a result, local planning is becoming a mix of multiple usual planning instruments, new optional tools, which have appeared with imported conceptions and widespread participatory practices. This article uses the context of Luhansk region to address the question how this variety of instruments transform the planning processes at the local level in post-transitional perspective. We examine how planning and participatory instruments are developed and combined in the territorial communities of Luhansk region, what are the outcomes and how the main actors evaluate the planning process.\u0000\u0000Methodology. In this article, we consider how territorial communities use the planning and participation instruments from the standpoints of spatial transformations and place-making, using the experience of the region with a severe planning crisis in recent decades. In order to analyze the state of use of planning and participation instruments at the local level, we focus on planning documents and participatory tools in 26 territorial communities of the government controlled areas in Luhansk region (as of the end of 2021). Additional data for contextualizing empirical information on the planning process, its outcomes and particular instruments were obtained from two focus groups, which involved 35 persons, including local officials, local activists and residents from different territorial communities of Luhansk region.\u0000\u0000Results. We argue that territorial communities rely on quite diverse planning documents and participatory practices with insufficient focus on planning instruments for balancing the spatial development. Active introduction of the new public participation tools that have become available in recent years had a paradoxical effect in the region, when implementing without reliance on planning instruments. At the same time, many territorial communities are adapting various instruments to specific local context, thus contributing significantly to developing the local institutional environment, creating local success stories and strengthening democratic decision-making. We show that planning instruments, their implementations and outcomes of planning activity in most cases are perceived and evaluated differently by the main actors, however many of them are becoming increasingly aware about planning process and interested in developing the planning culture.\u0000\u0000Novelty and practical significance. This paper contributes to the discussion on the evolution of local planning instruments, the role and effectiveness of certain instruments in the post-transitional perspective. Understanding the state of affairs with local planning and participatory instruments, their interplay and ability to provide expected outcomes contributes to strengthening of the local planning policy and makin","PeriodicalId":52802,"journal":{"name":"Visnik Kharkivs''kogo natsional''nogouniversitetu imeni VN Karazina Seriia Radiofizika ta elektronika","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78564652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
