The purpose of this work is to justify the feasibility of using the technology of microplasma sputtering from wire materials to obtain porous coatings for biomedical purposes, the modulus of elasticity of which is close to the corresponding characteristic of human cortical bone tissue. Analyzed the influence of the technological parameters of the microplasma sputtering regime on the degree of porosity of the coating.
Problem setting. The implementation of the European standards of life in Ukraine and the entrance of Ukraine into leading positions in the world, as defined by the “Ukraine – 2020” Sustainable Development Strategy, implies in the sphere of decentralization the departure from the centralized model of governance in the state, ensuring the capacity of local self-government and building an effective system of territorial organization of power in Ukraine, realization to the full extent of the provisions of the European Charter of Local Self-Government, the principles of subsidia
Problem setting. In general, the current level of integration and globalization processes requires a significant optimization of the existing transport system and its maximum adaptation to the requirements of European standards for the provision of transport services for the movement of passengers within urban agglomerations. The elimination of vertical state planning, financing and control in the field of public transport has caused a kind of chaos in the transport sector, because a new model of management and development has not been formed.
The article reveals the features of modelling the structure of the temple space, taking into account their symbolic-figurative and architectural-spatial implementation in church buildings of Byzantium and Rus-Ukraine. Sacralization of space and place through the manifested phenomenon of their consecration is created by the image and form of the temple building. The transformation of the planning and spatial solution of churches, from the domical bathylic to the form, shape, symbol, form creation, sacral, dome,
The method of obtaining nanocomposites based on polyamide-6 and montmorillonite intercalated by polyvinylpyrrolidone by precipitation from a solution in formic acid was developed in the work. The structure and physical interaction between the components of nanocomposites were studied by the methods of XRD, IR spectroscopic, and microscopic analyzes. The presence of polyvinylpyrrolidone in the structure of nanocomposites obtained from the solution was confirmed by IR spectroscopic analysis.
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 article presents schemes and models to support decision-making for the elimination of threats during emergencies in hierarchical systems. The construction of schemes and models was based on information and system technologies (based on the concept of identification).
