Abbreviations UsedPGacid reduced the resistance of the silica gel layer, thus hindering some manipulations with the chromatograms, for example, the detection of minor phospholipids [7]. Although the latter disadvantage was eliminated by decreasing the concentration of the boric acid, we could not obtain the desirable results.In order to find the appropriate solvent systems, we turned to bacterial lipidology, where PG and PE resolution is a routine task. In this field of science, the following solvent mixtures are usually used for one and two dimensional chromatography of phospholipids: chloroformlmethanollwater [a-131, chloroformlmethanoll acetic acidlwater [l 1, 13, 15-1 71 with different proportions of the components.

Safe land use of agricultural territories implies the mandatory preservation of the state's land resources, which are its crucial strategic resources. The relevance of this study is conditioned upon the abundance of issues of safe land use in Ukraine, specifically in the agricultural sector of Ukraine, not least due to the difficulties of exercising the citizens' right to safe use of agricultural land. The main purpose of this study is the theoretical investigation of the possibilities of ensuring the right to a safe environment upon using agricultural land in Ukraine, with an assessment of the real possibilities of its practical implementation in modern economic conditions. The basis of the methodological approach in this paper is a combination of methods of systematic analysis of key aspects of safe land use applicable to agricultural land, with the method of abstract-logical research of the main aspects of the exercise of the citizens' right to a safe environment upon using agricultural land in Ukraine. The main results obtained in this paper should be considered the definition of the main priority areas for the development of the available legislative system in Ukraine in the context of ensuring the safety of agricultural activities and the assessment of the role of the state in ensuring the proper level of environmental safety of agricultural land use in terms of the prospects for the preservation of the agricultural land available in the country. The results that were obtained in this study, as well as the conclusions formulated on their basis, have substantial practical significance for agricultural workers concerned about the qualitative solution of problematic issues concerning the ensuring and practical implementation of their legitimate right to a safe environment upon using lands that belong to the agricultural sector of the national economy

The article is devoted to the theoretical substantiation of cadastral activity as a legal category, which will further contribute to an in-depth understanding of this phenomenon and protection of the rights of owners and land users of land plots as objects of such activity. The article argues that the implementation of land cadastral activities involves active actions of authorized bodies, whose competence is also related to the implementation of cadastral activities and ensuring the functions of the State Land Cadastre. It is concluded that land cadastral activity can be considered an act of manifestation of legally defined, scientifically justified actions aimed at ensuring the technical, production and management activities of the relevant entities, which include public authorities and local governments, research institutions, land management organizations, etc., aimed at maintaining the land cadastre, organization and implementation of land cadastral works. It is substantiated that the maintenance of land cadastre, which should be considered as a complete information base, which contains information on the purpose and use, quantitative and qualitative characteristics of land, due to the objective needs of society in obtaining accurate and reliable information about land as a source of material goods and object property rights and taxation. Based on the analysis of legislative norms on cadastral activity in Ukraine, it is argued that the land cadastral system should additionally include information on resources that for some reason were left without an owner, or have errors in design; plots that have an owner, but are not used or inefficiently used in economic activities. This will allow to form a multilevel structure of the land market, increase the efficiency of state management of land resources in the country. The methodology of research of essence and signs of land cadastral activity is based on provisions of the general scientific dialectical method of scientific knowledge. In addition, formal-legal and formal-logical methods were used for full and comprehensive disclosure of the research topic.
