    Mutation of the Drosophila melanogaster L. under the influence of the electromagnetic radiation
    (Publishing House of Lviv Polytechnic National University, 2016) Nykyforov, Volodymyr; Sakun, Oksana
    Brief results of the previous studies of the effect of electromagnetic radiation on the fruit flies are quoted. The influence of electromagnetic radiation of industrial frequency on the living organisms has been investigated. Correlative dependence between phenotype Drosophila melanogaster L., duration and intensity of harmful factors has been established. Phenotypic manifestations have been fixed and Drosophila melanogaster L. mutation under the constant influence of the magnetic field induction from 2,25 to 20 μТ in three generations of test objects have been characterized. The dependence of the increased frequency of mutations occurrence and the increase of their diversity caused by the increase of magnetic field induction has been revealed.

    Reduction of the environmental threat from uncontrolled development of cyanobacteria in the waters of the Dnieper reservoirs
    (Publishing House of Lviv Polytechnic National University, 2016) Malovanyy, Myroslav; Nykyforov, Volodymyr; Kharlamova, Olena; Synelnikov, Alexander; Dereyko, Khrystyna
    We have analyzed the ecological hazard that has emerged as a result of the construction of hydropower plants on the Dnieper, which became the cause of uncontrolled development of cyanobacteria. The environmental risks that are caused by the uncontrolled development of cyanobacteria and their biodegradability were studied. The efficiency of application of the known methods of suppression of mass development of the blue-green algae was analyzed. The amount of biogas that can be synthesized from cyanobacteria biomass of Kremenchug reservoir was estimated. The strategy of avoiding the ecological disaster from the uncontrolled development of cyanobacteria and its negative impact on the environment was suggested.
