Relevance of the development of high-strength glass-ceramic coatings obtained by resource-saving technology for protective elements has been established. Structure formation mechanism in magnesium aluminosilicate glasses during heat treatment has been analyzed. Selection of the system was substantiated, model glasses and glass-ceramic materials on its base have been developed. Patterns of structure regularity and formation of the phase composition of glass-ceramic materials during their ceramization have been investigated.

The glauconite-polyaniline composites were prepared through oxidation of aniline using ammonium peroxodisulfate in aqueous solutions of phosphoric acid on the surface of a glauconite powder. Intermolecular interaction between amorphous polyaniline macromolecules and interphase coupling of polyaniline to the glauconite surface was confirmed by X-ray diffraction and FT-IR spectroscopy.

The purpose of this study is to identify the peculiarities of the formation and location in the structure of urban spaces, modern wooden temple architecture, its harmonious coexistence with the existing residential and public environment of Lviv. There is also a need to show the features of the material (wood) and its relief, namely the texture as a component of the perception of image and form, which accentuate the building of the temple in the urban spatial structure of Lviv.

The aim of the study is to analyze the physical processing properties and morphology of recycled plastics. The scope of work includes conducting the processing of primary PVC and recycled PVC and testing mechanical properties such as: tensile strength, stress, elongation and impact resistance, hardness. The scope of work also includes shrinkage testing of primary compacts and structural  investigation of the morphology of materials. The technology for producing the recycled composition is based on the extrusion and compression technology of the compositions obtained.

The pressing questions of methodology of cognition of scientific theories are considered. The scientific theories of modern jurisprudence, their structure are investigated. Development of jurisprudental theories is grounded in the general structure of scientific theories. Pay attention to the organization of law as a science. The problem of cost freedom of science, that us will interest different character and touch, is considered. It be comes firmly established that every science uses the tool of logic.

The article discusses the use of structured characteristic equations to develop programs setting system variables. The relative units system designed for calculation of a set of options of automatic control. The possibility of using these units investigated to simplify the mathematical description of the system.

Mixtures based on polypropylene (PP) and polyamide (PA) are of great importance as structural materials, the mixing of which reduces the negative characteristics of the original polymers. Non-polar PP significantly reduces water absorption of the material during mixing with polar high hydrophilic PA. As a result, the effect of moisture on the mechanical and thermal properties of the composites decreases. On the other hand, mixing PP with PA can extend the temperature range of material exploitation at negative temperatures.

Analyzed ukrainian student internet publications, described the features and structure of online periodicals, which affects on its functioning. Many diverse information about student life can be on student websites. Nowadays every higher education institution creates its own information site. Exploring students' online portals, you can see certain features, but the majority of student Internet publications in Ukraine in no way unrelated with sites of higher educational institution or university.

The article describes the research of the peculiarities of methods and algorithms for the recognition of mathematical expressions. The possibility of simultaneous execution of structural analysis and classification of characters is investigated. The process of classification of the symbols and construction of the corresponding system, based on methods of machine learning, is described. The developed iterative algorithm is implemented in the design of the intelligent information system for the recognition of mathematical expressions.
