Towards the abyss: the influence of parents’ alcoholism on the development in adolescence
(Lviv Polytechnic Publishing House, 2015) Khomik, Khrystyna; Honcharenko, Yelyzaveta; Lviv Polytechnic National University
The article presents a theoretical overview of the problem of deviations in adolescents who are determined by alcohol dependent parents. The behavior of alcohol dependent parents or one of them creates an atmosphere in the family, which inevitably creates resistant and mental sets in adolescents on the consumption of alcohol and updates the assimilation of norms and stereotypes of deviant behavior. The results of systematic use of alcohol that are manifested in the family, less visible to the public, but the nature and depth of its actions are the most dangerous and harmful. So, the most difficult consequences of alcohol dependence of parents for adolescents are the following: 1) the desire to consume alcohol; 2) increase in aggression and conflict, irresponsibility, which eventually can lead to antisocial behavior; 3) the emergence of vagrancy as a form of deviant behavior.

The article Identifies main benefits from collection of taxes on real property distinct from plot of land for local governments and taxpayers. The problems of the modern system of property taxation are analyzed. The main disadvantages of charging to local budgets in compliance with recent changes to the Tax Code of Ukraine from 12.28.2014 are identified. Proposals for improvement of budget legislation in the part of property taxation are made. Expediency to set the equal tax rate with privileges rejection for the payment of property tax is suggested.
Impact of the operating mode of neutral in 35 kV power grids on the arc overvoltages and voltage teasuring transformers
(Lviv Polytechnic Publishing House, 2015) Yatseyko, Andriy; Andrushko, Volodimir; Lviv Polytechnic National University
Has been analyzed possible methods of earthing of neutrals in 35 kV power grid. Among the most common injuries in these electrical system are arc circuits, that is why the dependence of overvoltage multiplicities on the nature of earth arcing and on the method of earth arrangement of electrical system neutral. Given that in 35 kV power grids may arise ferroresonant processes, operation of voltage measuring transformers has been researched during unstable earth arcing.
Attitude towards psychological knowledge in Ukrainian society
(Lviv Polytechnic Publishing House, 2015) Kuta, Oksana; Lviv Polytechnic National University
There are a lot of problems in Ukrainian science. Old fashioned educational programs and students who are not interested in personal growth and professional development are some of them. We believe that all these results in misunderstanding and mistrust to the psychological science in Ukraine. People of different age might use psychological knowledge in everyday life more often – in case of solving personal difficulties problems or for improving quality of life. The results of empirical study of use of psychological knowledge among ordinary people are presented.

Influence of poly(vinyl chloride) and polymer-silicate fillers on the properties of polyester resin
(Lviv Polytechnic Publishing House, 2015) Katruk, Diana; Levytskyi, Volodymyr; Lviv Polytechnic National University
The influence of polymer modifier poly(vinyl chloride) (PVC) and polymer-silicate fillers on the physicochemical regularities of structuring of unsaturated polyester resin have been investigated. It has been ascertained that addition of Zn-silicate fillers in polyester composition leads to slower curing speed, and the introduction of Ni-silicate fillers and PVC leads to accelerate the process of curing polyester oligomers. Physical-mechanical and corrosion properties of polyester materials modified by polyvinyl chloride and polymer-silicate fillers have been determined.

Structure and properties of diffusion boride layers on steels obtained at applying external magnetic field
(Lviv Polytechnic Publishing House, 2015) Chernega, Svitlana; Poliakov, Ihor; Grinenko, Catherine; Krasovsky, Michael; National Technical University of Ukraine "Kiev Polytechnic Institute"; Frantsevich Institute for Problems of Materials Science NAS of Ukraine
Investigated the structure, phase composition, microhardness and wear resistance boride coatings obtained on carbon steels at complex saturation with boron and copper in various physical and chemical conditions, namely carrying satiation without application of an external magnetic field (EMF) and in its simultaneous imposition. Established that the application EMF on carbon steels formed a continuous, homogeneous boride layer, thickness is 2 times higher than the boriding without EMF. Formation diffuse boride layers under the action EMF improves tribological characteristics and leads to an increase in wear resistance of 2.2 – 2.6 times.

In this paper described for the first time neural network technology developed to zoom out images scale. The developed method uses a neural structure model geometric transformations to establish the connections between frames pairs of images of high and low resolution. Adjusted so in the learning process synaptic scales allow to change the scale of images of one class without substantial loss of quality.
Filling of polymer hydrogels by nanoparticles of the hydroxyapatite
(Lviv Polytechnic Publishing House, 2015) Borova, Solomiya; Chobit, Maksym; Tokarev, Viktor; Lviv Polytechnic National University
In this work was development of new methods of synthese the hydrogel composites with nanoparticles of hydroxyapatite using sol-gel synthesis. At first the nanoparticles were synthesized in the presence of the peroxide oligomers which at the next stage provided polyacrylamide grafting on to the surface nanoparticles; that resulted in formation of the powder-xerogels capable to turn in to hydrogels. In accordance with other approach, the hydrogels filled were formed via in situ synthesis of the hydroxyapatite nanoparticles directly inside of the crosslinked polyacrylamide gels. The shape, composition and structure of the hydroxyapatite nanoparticles as well as polymer composites were investigated applying gas-liquid chromatography, X-RD analysis, scanning electron microscopy.

Features of distribution of granules on device height are investigated. The analysis of results of measurement of temperature fields in the vortex granulator (single-phase and two-phase flow) is submitted. Received results of researches will allow to develop mechanisms to control the movement of granules in the working space of the vortex granulating equipment and kinetics of removal of moisture from them.
Study of vertical movements of the European crust using tide gauge and GNSS observations
(Lviv Polytechnic Publishing House, 2015) Tretyak, Kornyliy; Dosyn, Solomiya; Lviv Polytechnic National University
This research is devoted to the study of vertical movements of the European crust on the basis of two independent methods, namely tide gauge and GNSS observations results. The precision with which the movement of the earth's crust according to the results of tide gauge observations can be explored has been calculated. A methodology to identify the duration of tide gauge observations required for studies of vertical movements of the earth's crust has been presented. Approximation of tide gauge time series with the help of Fourier series has been implemented, the need for long-term observations in certain areas has been explained. The diagram of the velocities of the vertical movements of the European crust on the basis of the tide gauge data and GNSS observations has been built and the anomalous areas where the observations do not coincide have been identified.
Space-functional role of consortiums of ecotones of protective type to ensure the environmental safety on railway lines
(Lviv Polytechnic Publishing House, 2015) Ruda, Maria; Pohrebennyk, Volodymyr; Ukrainian National Forestry University; Lviv Polytechnic National University
A multi-factor analysis of the impact of the Lviv Railway transport on the environment takes into account the properties of natural systems: multiple connections, stability, commutability, additivity, invariability as well as multivariable correlation of nature components. One of the important steps towards ensuring environmental safety in the railway transport is the formation of ecologically balanced system of nature management on the basis of environmentally clean technologies. A fundamentally new model of environmental safety in railway transport is of great polyfunctional importance as this enables, on the basis of the landscapeecological methods, to form consortiums of protective ecotones that will provide the maximum spatial-temporal efficacy.
