An important factor in the scientific and educational process in higher education is the local library of the respective educational institution. The local library offers the use of the local library information system and more precisely the Online Public Access Catalog (OPAC) to perform a lot of reference and research activities for the mentioned process. As the name suggests the system usually works online and has a web-based interface that allows working with it remotely over the Internet using a regular web browser. The present study aims to reveal the share of these systems in the Bulgarian university libraries by conducting empirical research. The survey covers all 51 Bulgarian higher education institutions accredited in 2019. The main scope of the study is the "Online public access catalogs" which is an essential part of each library information system. [ABSTRACT FROM AUTHOR]

The goal of this study is to construct doctrinal and legal grounds of the doctrinal and legal grounds of the complex modelling of legal regulation of right-and-duty of an individual on providing the comfort conditions of environment with authors' scientific and practical proposals. This article consists of five chapters and conclusion. The first one is devoted to the problems of intensification of the processes of the technological modernization of the modern society. The second one is about legal regulation of these processes as a factor of minimization of its destruction impact on environment. Third chapter described the principle of unity of the right on comfort conditions of environment and the duty to protect and develop it. The forth one deal with the constitutional principle of ecological (nature-protect) state as legal realization of imperative on providing comfort conditions of environment. The fifth chapter is devoted to the essence, main directions and significance of the integration of Russian legal system into the international system of legal providing comfort conditions of environment. In the study the systemic, comparative, sociological and statistical methods are used. [ABSTRACT FROM AUTHOR]

The works on geological prospecting may be conducted in Russia only on the basis of license for subsoil use. One of the mandatory requirements in such license is the conducting of environmental monitoring. But, legislative regulations for this monitoring are not established and there is a lack of corresponding methodical literature too. At the request of one company our team developed a generalized technique of environmental monitoring for use during search and exploration of oil and gas deposits at the license areas of the Middle Urals, Russia. The technique is based on a common methodology of biosphere monitoring with account of the specificity of prospecting works. On the basis of analysis of forecasted impacts on the environment, there were defined stages, objects, kinds and volumes of works, as well as lists of controlled characteristics. The technology of oil and gas deposits exploration comprises two consecutive stages, which are essentially different in nature of impact on the environment. In the first phase, there is conducted the study of the area by geophysical methods (the gravimetric and seismic methods). At the second step, the drilling and testing of exploration wells are carried out. The technique of environmental monitoring of the territory of license areas includes three stages. The first stage is performed prior to the beginning of prospecting works in order to determine the background levels of the studied parameters. The second stage is performed in a period of conducting the complex geophysical works. And, the third stage is performed during the drilling and testing of wells, including their elimination and reclamation of disturbed areas (in case of absence of the industrial oil and gas deposits). The technique foresees monitoring of atmospheric air, surface and ground water, soil, radiation background and the testing of drilling sludge. The objects of monitoring are: the territory of license lot, the drilling plots and the pit for drilling sludge storage. The list of studied characteristics includes more than 20 items. The technique is presented in the form of table which contains all necessary information for conducting of monitoring. [ABSTRACT FROM AUTHOR]

Land-use regression (LUR) models are successfully used in Europe and United States of America in recent 10-15 years for atmospheric air pollution description. The models provide getting the air pollution maps on a large area with high spatial resolution (~ 10 m) and relatively small financial and time costs. The paper is devoted to assessment of the land-use regression (LUR) method applicability for description of snow cover's pollution. Snow may be used as a good indicator of air pollution in many Russian regions where snow lies about 4-6 months a year and accumulates all substances coming from atmosphere. The assessment was done for Karabash city, which is one of the most polluted Russian cities due to long activity of «Karabashmed» copper smelting plant. The study showed that the LUR method can be successfully applied for description the dust deposition density from atmosphere and further use as a part of environmental monitoring systems.
