The effect of the water steam on the sulphur removal degree and conversion level of coal organic matter has been determined. Sulfur content, as well as ash content and volatiles yield depend on the mentioned values. The optimal the content of water steam in oxidants to realize the oxidative desulphurization process has been found with the aim of obtaining raw material for pulverized coal production.

За присутності різних каталізаторів (TiCl4, AlCl3, H2SO4) досліджували одержання кумарон-інден-карбазольної смоли (КІКС), що виробляється з рідких продуктів коксування вугілля і надалі застосовується для модифікування бітумів. Вивчено вплив типу каталізатора на вихід та модифікувальні властивості КІКС (зміну термопластичних та адгезійних властивостей бітумів у разі додавання до них отриманих смол). Встановлено вплив кількості каталізатора в реакційному середовищі на синтез смоли та подальше модифікування нею бітумів. Згідно з одержаними результатами вибрано оптимальний тип та кількість каталізатора для отримання КІКС. Також встановлено, що кумарон-інден-карбазольна смола, синтезована з використанням вибраного типу каталізатора і визначеної оптимальної його кількості, максимально позитивно впливає на адгезійні характеристики дорожнього бітуму.
Social-pedagogical work with a dysfunctional family in the Ukrainian context
(Lviv Politechnic Publishing House, 2017-02-20) Shved, Maria; Duzha-Zadorozhna, Myroslava; Pukaliak, Marta; Ukrainian Catholic University; Lviv Polytechnic National University
The modern Ukrainian society is experiencing a period of socio-political transformations, economic crisis and is searching for new strategies of its social development. Under these conditions, the notion of family undergoes considerable changes, which have a negative effect on its everyday activity. According to the socio-pedagogical approach, families can be thus classified: well-to-do, seemingly problem-free, at-risk family and family in crisis. Social threats (migration, terrorism, organized crime, environmental crisis etc.) have negative influence on family’s creation and development. Urgent problems of the Ukrainian family are: orphanage, migrants and refugees, loss of the contact with family members due to forced migration, social orphanhood, decrease in educational and socializing potential, poverty. These problems increase the number of problem families and disadapted children and youngsters. Disadaptation is the consequence of disorders in the process of social adaptation, during which the individual acquires necessary skills and patterns of behavior and changes the environmental conditions, according to his needs and abilities. To overcome the problems mentioned family needs professional help. In order to devise methods of sociopedagogical work with families in crisis, its stages, methods, models and principles were described in this article. The works of S. Jones, R. Joss, F. Loewenberg, R. Dolgoff were used to define the models of socio-pedagogical support of disadapted children (paternalistic, contact, instrumental, personalistic). A set of methods was used in this research – selection, analysis, professional literature systematization and generalization, comparative method for analysis of research data, method of theoretical generalization etc. To sum up, it can be stated that in Ukraine the problem mentioned still lacks for precise methodological research and scientific techniques of cooperation with problem families. This encourages the creation of a complete system based on international experience and modern technologies, which allows preparing specialists in social-pedagogy.
