The article considers the possibility of reducing the man-made load on surface and ground waters in Lysychansk-Severodonetsk industrial agglomeration caused by numerous sludge collectors and tailings storage facilities of various industries formed many decades ago. The paper provides information on the location and technical condition of the sludge collectors of the liquidated "LYSSODA" manufacture (Luhansk oblast), the amount of waste currently stored in them as well as the impact of these wastes on the quality of groundwater in the area where the sludge collectors are located.

In artistic and stylistic terms, the architecture of Lviv's sacred buildings during the 16th-18th centuries was marked by a variety of appearances. The builders paid great attention to the plastic expressiveness of the building. The facades of sacred buildings were richly decorated, had a clear system of horizontal divisions of cornices and belts, carved in stone with ornamental carvings window frames, and portals of entrances.

The article highlights the topical problems of searching for new methods of using font and image elements in project design methodology of compositional integrity of graphic identification development for packaging of consumer goods.

Research purpose of the article is to outline and investigate the methods of reflecting identification of packaging with the help of author's unique image and font composition.

The article traces the history of the origin of the Manyavsky Hermitage and reveals the stages of development of the monastery from the beginning of its foundation and formation, prosperity to the decline, destruction and revival in our time. In the course of the research, the architectural-spatial and planning structure of the monastery ensemble of the Exaltation of the Holy Cross in Manyava were analyzed.

The main physical-mechanical and thermophysical characteristics of composite materials based on epoxy resin ED-20 and peroxide resin ED-20P (modified with tert-butyl hydroperoxide ED-20 of a molecular weight 480) in the ratio of 30 mass parts of ED-20P to 70 mass parts of ED-20 and unsaturated oligoester TGM-3 were researched. Butyl methacrylate was used as the active diluent of epoxy-oligoester mixtures. The polyethylene polyamine was used as hardener in a steochemical ratio. For the comparison we studied compositions which did not contain ED-20P resin.

In order to improve the properties of epoxy resins they are modified by the various compounds, in particular oligoesters. Compositions based on ED-20 epoxy resin and unsaturated oligoesters are structured in the presence of polyethylene polyamine (PEPA). The oligoester acts as a plasticizer that is not chemically bounded to the molecules of spatially crosslinked structure. It leads to the deterioration of their physical, mechanical and chemical properties during the working process of film based on epoxy-oligoester compositions.

The aim of the given article is to trace the origins of common forms of space and plasticity in railway station buildings in Halychyna (Galicia) and Tyrol and reveal their most important features and trends in their formation.

The thesis is devoted to the development of theoretical bases of the corrosion resistance of concrete by protective coatings on the base of polymethylphenylsiloxane filled with aluminum and zinc oxides. The technological properties of protective coatings compositions were investigated by methods of physical and chemical analysis, methods of the concrete surface coating and form conditions were shown. Determined that the forming matric-oxide structure covering in the process of hardening passpasses behind counting polymerization polymethylphenylsiloxane.
