Actual ecologically friendly solving of problem of municipal sludge
(Lviv Polytechnic Publishing House, 2016) Kalinichenko, Kira; Nikovskaya, Galina; Ulberg, Zoya; F. D. Ovcharenko Institute of Biocolloidal Chemistry
A new eco-friendly process for rational utilization of toxic municipal sludge wastes by their transformation into fertilizer for land application has been developed. It includes promotion of alkaline vector of heterotrophic microbial metabolism in high stable biocolloidal sludge system by adding special nutrients, heavy metals leaching and sludge suspension separating under the action of microbial metabolites. Each of the phases (sediment and bioextract) can serve as a fertilizer after procedure of additional stabilization. The fertilizers obtained satisfy the EU limits for the materials of agricultural utilization. The vegetation experiments have shown that the fertilizer application results in tenfold increase of plant harvest and provides high quality of target product.

Analysis of coke gas properties at operation of its metering systems
(Lviv Polytechnic Publishing House, 2016) Dzhyhyrei, Viktor; Matiko, Fedir; Lviv Polytechnic National University
The generalization and analysis of coke oven gas composition using the data of literary sources and coke enterprises are carried out in the paper. The range of pressure and temperature of coke gas during transportation is defined. The physical properties of coke gas (density, compressibility factor, adiabatic index, dynamic viscosity) that are the part of the equation of gas flowrate by method of variable differential pressure are investigated in the defined range of pressure and temperature. 25 gas mixtures with different composition were synthesized in order to make the analysis of dependency of physical properties versus pressure, temperature and composition of the mixtures. According to the results of the research the recommendations for the development of simplified methods for calculating the physical properties of coke oven gas are made.

Application of alloyed industrial oil in friction units of power equipment
(Lviv Polytechnic Publishing House, 2016) Kovalenko, Tetiana; Serdiuk, Vitalii; Lviv Polytechnic National University
Polyfunctional lubricant performance properties indicates its significant impact on the longevity and efficiency of work of contact pairs. Therefore, the correct choice of lubricant depends on energy consumption to overcome friction, wear of rubbing surfaces. The most economical way for the improvement of work of the friction units in different environmental conditions is the development of new lubricant compositions with the addition of an effective multifunctional additives as so base oils don't meet all of requirements put forward to them. The polymethacrylate additives with enhanced functionality were obtained in this work. The influence of the concentration of the additives on the viscosity-temperature, depressor and anti-wear properties of industrial oil I-20A were studied. Found that received additives improve the performance properties of oil-20A, respectively, contribute the reliable lubrication of the friction units in power plants at different natural conditions.
Application of liquid glass (SiO2) on textile products
(Lviv Polytechnic Publishing House, 2016) Dogan, O.; Dag, R.; Necmettin Erbakan University
Liquid SiO2 solutions produced by silicon-based nano- powder are covered on the fabric surface by using spray method. Fabric surfaces were coated at the room temperature in air with the different spray nozzles. Surface analysis of the coated fabric was performed by using Contact Angle and SEM pictures. According to the Contact Angles measurements, the coated fabric surfaces showed hydrophobic character between 126 and 146 degrees, and the SiO2 particles sticked to the fabric fibers as seen from SEM picture.

As a source for relationships between individuals: social capital and sense of community
(Lviv Polytechnic Publishing House, 2016) Eroglu, S. Erkan; Selcuk University
Determination of community social dynamics in a society is recognized as increasingly important for sociology for the last decades. Studying community social dynamics occurs under a variety of headings. These are; ‘sense of community’, ‘community competence’, ‘neighborhood relations’, ‘community cohesiveness’, ‘community capacity’ and ‘social capital’. The newest and latest heading among these is social capital. Sense of community is more established and has been researched increasingly for a long time. Many outcomes of individual social life are thought to be related to social capital and sense of community. These outcomes include quality of life, income inequality, life expectancy, marital relationships, kinship relationships, and job relationships. Social capital is a concept in variety of social sciences that refers to connections within and between social networks. Sense of community is a concept which focuses on the experience of community rather than its structure, formation, settings or other features. In this framework, the scope of the study is to define social capital and sense of community in general. Description of social capital and sense of community key concepts and determination of their components form the content of the study. Subject and scope of the study were determined, the basis of the study can be summarized in the following sentence; “Relationships are crucial”.
