M. Beketov National University of Urban Economy in KharkivThe challenge of transport mode choice is one of core logistics tasks. The plenty of solutions of this task is based on the main features of transport and can not be used for specific situations effectively. Researching of delivery variants of lime bricks is actual seeing rapid development and possibility of using diverse transport packaging. Equivalent distance calculation allows to determine the scope of using rail and road transport. In contrast to the existing approaches of calculating of equivalent distance, this paper is proposed to use customer’s cost as criterion of transport mode choice, including immobilisation cost while transporting goods.Item Determination of cost of contra-rotating wind turbine with transformer with rotating half(Lviv Polytechnic Publishing House, 2015) Kovalchuk, Andrii; Khai, Vasyl; Lviv Polytechnic National UniversityFor effective use of low-speed potential of a wind use low-power wind turbines with vertical axis of rotation (VAWT). A new design of contra-rotating noncontact VAWT in which two wind rotors rotate in opposite directions is proposed. The contactless transmission of generated power from the multipole permanent magnet synchronous generator (PMSG) and the regulation of electric power carries a special device – a transformer with rotating half (TRH). The cost of VAWT of the classical and offered sample is determined. The offered design of contra-rotating VAWT has till 42 % lower cost than a traditional design of wind turbine with vertical axis of rotation, and this cost advantage grows with reduction of power.Item Monitoring of performance of the municipal wastewater treatment facilities(Lviv Polytechnic Publishing House, 2015) Shandrovych, Vira; Malovanyy, Myroslav; Lviv Polytechnic National UniversityThe paper has engaged monitoring of performance of the municipal wastewater treatment facilities of Lviv by analyzing the average monthly data of their operation, obtained in a chemico-bacteriological laboratory of the Lviv City Utility Enterprise "Lvivvodokanal". Also, performance of aerotanks of the same facilities has been studied by carrying out check measurements of the concentration of dissolved oxygen and ammonium in them.Item Shear strength of RC beams strengthened by FRCM system(Lviv Polytechnic Publishing House, 2015) Vegera, Pavlo; Khmil, Roman; Blikharskiy, Zinoviy; Lviv Polytechnic National UniversityIn this article shear strength of strengthened and non-strengthened reinforced concrete (RC) beams are described. Beam was reinforced by FRCM system Ruredil XMesh Gold. There was using strengthening type called jacked – textile coated beam from all beam’s surfaces. Effect of strengthening inclined cross section is 24.1%.Item Estimation of the tax potential as a part of budgetary potential(Lviv Polytechnic Publishing House, 2015) Zhebchuk, Roman; Yuriy Fedkovych Chernivtsi National UniversityThe author describes the method calculating of tax potential in the process of budget planning as part of the budgetary potential.Item Analysis of the traffic`s flow distribution by the types of drivers’ temperament(Lviv Polytechnic Publishing House, 2015) Postranskyy, Taras; Sotnikova, Anna; Lviv Polytechnic National UniversityThis paper shows the results of the survey of determining the ratio of drivers by types of temperament in the transport flow that are necessary for further studies of driver’s psychophysiology. Actuality of this issue consists in the necessity to take account of the driver’s type of temperament as the main road traffic participants, which is one of the key factors of any behavior in difficult traffic situations.Item The kinetics of oxypropionic acid on natural zeolite(Lviv Polytechnic Publishing House, 2015) Gyvljud, Anna; Sabadash, Vira; Gumnitskij, Jaroslav; Lviv Polytechnic National UniversityThis paper presents the results of experimental studies of the kinetics of ion exchange adsorption of lactic acid by zeolite in the periodic conditions. The results of experimental studies make it possible to determine the kinetic coefficients of the diffusion process.Item The peculiarity of thin border between people’s chronotypes and the level of labour productivity(Lviv Polytechnic Publishing House, 2015) Novikova, Anastasiia; Bilyk, Olena; Lviv Polytechnic National UniversityThe peculiarity of thin border between people’s chronotypes and the level of labour productivity is considered.

The rate constants increase with the increase in the excess of one of the reactants. The change in the effective rate constants is described by the Michaelis–Menten equation indicating that the reaction proceeds through the initial equilibrium stage of formation of an intermediate complex which then transforms into the product. The effective rate constants, the equilibrium constants of formation of the intermediate complex, and the rate constant of its transformation into the reaction product were determined, as well as the thermodynamic parameters of the formation of the intermediate complex and the activation parameters of the transformation of the intermediate complex into the product. The limiting stage of the reaction is established and its mechanism is suggested.Item The role of strategic planning technologies in terms of European cooperation development(Lviv Polytechnic Publishing House, 2015) Petryshyn, Nataliia; Kateryna, Dziubina; Lviv Polytechnic National UniversityThe article is devoted to the essence and peculiarities of strategic planning technology, its introduction by domestic enterprises in terms of European cooperation development. The features of strategic planning are explored. The problems of implementation and factors that determine the choice of a particular strategic planning technology is clarified.Item Image structure evaluation by statistical intensity features(Lviv Polytechnic Publishing House, 2015) Melnyk, Roman; Boyko, Iryna; Lviv Polytechnic National UniversityIn this paper an extraction of intensity variance, size-intensity mean features and color concentration is considered. Their effectiveness is evaluated for image structure analysis.Item Formation of polymer microcapsules with encapsulated Fe3O4 magnetic nanoparticles(Lviv Polytechnic Publishing House, 2015) Melnyk, Roman; Serdiuk, Vitalii; Kovalenko, Tetiana; Lviv Polytechnic National UniversitySurface functionalized iron oxide magnetic nanoparticles (MNPs) are a kind of novel functional materials, which can be widely used in biotechnology and catalysis as magnetic separation systems.

Magnetite MNPs modified by oleic acid were synthesized and used in encapsulation process. Developed encapsulation technique allowed to obtain microcapsules with Fe3O4 nanoparticles encapsulated in paraffin core possessing magnetic properties and covered by heterofuntional copolymer shell.Item Income tax on individuals as a tool impact population welfare(Lviv Polytechnic Publishing House, 2015) Khymych, Oksana; Shkilna, Valentyna; Lviv Polytechnic National UniversityInvestigated the tax on personal income in Ukraine in modern conditions. Present briefly the major changes that occurred in the administration of personal income. Determined that there have been significant changes in the personal income tax. The study of changes in the personal income tax as a tool to influence the welfare of the population, we can conclude that the problem of raising living standards rise sharply in today's environment.
