    Landscape metrics for changes detection in land cover of the west polesie transboundary biosphere reserve
    (Lviv Politechnic Publishing House, 2017-11-12) Alokhina, Olga; Ivchenko, Dariia; Koshovy, Volodymyr; Rusyn, Bohdan; Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine
    The actuality of the present paper is substantiated by the need in preservation the landscape and biological diversity of nature-protected territories to achieve the ecologically optimal structure of land use as one of the main targets of their sustainable development. The paper describes methodological approaches to analysis of the nature-protected territory landscape diversity, presents the landscape metrics, calculated using the FRAGSTATS software as well as images of their spatial distribution.

    Distributed system for monitoring and forecasting of water bodies quality
    (Lviv Politechnic Publishing House, 2017-11-12) Sanginova, Olga; Bondarenko, Sergii; Andriiuk, Valentyna; Kraieva, Kateryna; Igor Sikorsky Kyiv Polytechnic Institute
    The structure and principles of constructing a distributed monitoring and forecasting system for water bodies quality designed to forecast the state of water supply sources in the remote mode are considered. The database of water bodies of Ukraine for storing the received data, including the data from the nongovernment and international organizations, is implemented. The interaction between the distributed subsystems is carried out via the client-server architecture.

    The methodology for design of informational and analytical system for environmental monitoring of mining and chemical enterprise in the liquidation
    (Lviv Politechnic Publishing House, 2017-11-12) Pohrebennyk, Volodymyr; Dzhumelia, Elvira; Lviv Polytechnic National University
    The impact of the mining and chemical enterprise on the state of pollution of the environment was assessed in the paper. The need to design an informational and analytical system for monitoring the territory of Rozdil state mining and chemical enterprise (SMCE) “Sirka” at the stage of the liquidation was proved. It was established that it is necessary to create an informational and analytical system of environmental monitoring, which will increase the ecological safety of the territory of the enterprise and the surrounding settlements.

    Improved technology of biodiesel fuel production from waste oils
    (Lviv Politechnic Publishing House, 2017-11-12) Kukushkina, Olena; Vasylkevych, Oleksandr; Bondarenko, Sergii; Igor Sikorsky Kyiv Polytechnic Institute
    The process of biodiesel fuel production from waste oil is investigated. It is identified that when processing used oil, the raw material needs aftertreatment, and the presence of free fatty acids in the oil leads to the appearance of an additional reaction The ways of improvement of technological scheme for biodiesel fuel manufacturing taking into account raw material characteristics are offered.

    Multispectral control of pesticide concentrations in aquatic environments using bioindication on phytoplankton
    (Lviv Politechnic Publishing House, 2017-11-12) Kvaternyuk, Sergey; Vinnytsia National Technical University
    The aim of the work is to improve the method and means of multispectral measurement of the content of unsuitable chemical plant protection products in aqueous media using bioindication on phytoplankton. The article analyzes the errors of indirect measurements and the reliability of the control of the concentration of pesticides using the developed means of environmental monitoring of integral parameters of pollution of water bodies.

    Dynamics modeling of traffic-related exhaust aerosols
    (Lviv Politechnic Publishing House, 2017-11-12) Sheludchenko, Lesya; Kamyanets-Podilsky, Khmelnitsky region
    The results of analytical researches of migration processes and turbulent diffusion of exhaust aerosols, produced by traffic flows within reserve technical lanes of highways are given. It is concluded that rotors, determined as some areas of the rotary motion of an aerosol, are always formed within the diffusion divergence field of turbulent flows of exhaust aerosol.

    Determining the level of resources savings of the product life cycle
    (Lviv Politechnic Publishing House, 2017-11-12) Komarysta, Bohdana; Bendiuh, Vladyslav; National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”
    We proposed to use a useful life index to take into account the time of decay in the environment of the product and the time of useful product use. Application of a waste generation index to assess the level of waste generation at the stage of the product life cycle is suggested. The unitary index of efficient use of natural resources is calculated on the basis of thementioned indices.
