    Theoretical and practical aspects of the efficiency of application of mineral fertilizers encapsulated with polyethylene terephthalate
    (Видавництво Львівської політехніки, 2020-02-10) Synelnikov, Serhiy; Malovanyy, Myroslav; Nahurskyy, Oleh; Luchyt, Liubov; Petrushka, Kateryna; Tymchuk, Ivan; Stokaliuko, Oleh; Lviv Polytechnic National University; Lviv State University of Life Safety
    The environmental impact of residual mineral fertilizers not utilized by plants is analyzed. It is shown that this negative effect extends to all elements of the environment: soil, atmosphere, hydrosphere. The perspective of the application of encapsulated mineral fertilizers that allow prolonged release of plant nutrients is outlined. The appliccation of modified polyethylene terephthalate (PETF) as a capsule-forming material for encapsulated mineral fertilizers is proposed. PET modification and fertilizer encapsulation technologies have been tested. The dynamics of the release of nutrients from fertilizers encapsulated by PET has been studied. The kinetics of watercress salad growth with the use of granular and encapsulated fertilizers has been investigated.

    Determination of significant factors of landslide processes and flooding
    (Видавництво Львівської політехніки, 2020-02-10) Katkov, Mykhailo; Malovanyy, Myroslav; Kotsiuba, Iryna; Senchuk, Tetyana; Lavinda, Maryna; Kharkiv National University of Urban Economy named after O. M. Beketov; Lviv Polytechnic National University; Zhytomyr Polytechnic State University
    The linear dependence of some geological (significant) factors responsible for landslide and flooding processes on the cost of geotechnical surveys determining these factors was proved. The principle of selection of engineering-geological surveys, which assess the factors of occurrence of landslide and flooding with high probability, was developed. The possibility of identifying economic territories that may be susceptible to landslide and flooding processes based on already existing basic data of previously conducted engineering-geological surveys is substantiated. A preproject (planned) method of calculating the costs of geotechnical surveys based on the existing basic data is proposed.
