    Multispectral ecological control of biomass of phytoplankton in aqueous media in situ using a quadrocopter
    (Lviv Politechnic Publishing House, 2018-02-01) Kvaterniuk, Serhii; Petruk, Vasyl; Vinnytsia National Technical University
    The aim of the work is to improve the method and means of multi-spectral ecological control of phytoplankton biomass in water environments in situ using a quadrocopter with a multi-spectral camera. The instrumental and methodological errors of indirect measurements of phytoplankton biomass in the near-surface layer of the aquatic environment using the developed means of environmental control have been analyzed.

    Environmental safety of water bodies and coastal areas using the method of water environment bioindication by means of macrophytes
    (Publishing House of Lviv Polytechnic National University, 2016) Bondarchuk, Olga; Petruk, Vasyl; Kvaterniyk, Sergiy
    The purpose of this work is to improve the ecological state of water bodies and coastal area of the “Enerhoharant” LLC company by implementing a series of environmental measures based on research of their ecosystems and environmental-economic assessment that will enable largely to solve the problem of optimal use of natural resources for the recreational purposes.

    Mathematical modelling of the population dynamics of hunting mammals based on recurrent equation system
    (Publishing House of Lviv Polytechnic National University, 2016) Trach, Іryna; Petruk, Vasyl; Kvaternyuk, Sergy; Titov, Тaras
    Regression analysis of the population dynamics of hunting mammals based on Khmilnytskyi forestry was made. Correlation analysis of the observations results between the populations of spotted deer and wisent, spotted deer and wild boar, lepus and fox was made. Modelling of the population dynamics of hunting mammals was done using Mathcad based on the system of recurrent logistics equations and the adequacy of the model by the Pearson's criteria was proved.

    Ecological safety of visual environment and videoecological perception (VEP) of Vinnitsia
    (Publishing House of Lviv Polytechnic National University, 2016) Bondarchuk, Olga; Petruk, Vasyl
    The object of the research is landscapes of the urban ecosystem of the town of Vinnytsia. The purpose of the work is to investigate and evaluate the level of videoecological perception and geopotential sustainability of Vinnytsia and set the main risks to natural and artificial visual environment of the city. The paper deals with the method of calculation for the evaluation of videcoecological favourableness of the urban environment and methods of visual pollution control in the urban environment. During the research videoecological perception of the town of Vinnytsia was analyzed, the main environmental risks of the technosphere were identified and an evaluation of the sustainability of the urban environment of the city was made; the ways to optimize visual sensitivity of natural and artificial environment in the city were reviewed. A map-scheme based on experimental data and patterns of the range of videoecologiacal perception was made and its distribution among the territory of Vinnytsia was shown.

    The concept of environmental safety of Vinnytsia region in the waste management sphere
    (Publishing House of Lviv Polytechnic National University, 2016) Petruk, Roman; Petruk, Vasyl; Ishchenko, Vitalii; Kvaterniuk, Sergey
    The aim of the research is to collect the information and analyze integrated systems of municipal solid waste (MSW) management and treatment in Vinnytsia region for its further optimization. The state of landfills and waste dump sites in Vinnytsia region, existing MSW collection system (container availability) and waste transportation system (availability and frequency of transportation) in all districts of Vinnytsia region, legal framework in the field of solid waste management, the state of public awareness and public opinion on MSW management in Vinnytsia region are analyzed; recommendations for environmental safety of Vinnytsia region in the waste management sphere are given.
