Findings on the effect of neutralizing substances on rheological properties of products of the destruction of collagen-containing materials are presented. The dependences between the shear velocity and shear stress and between shear stress and viscosity of the products of alkaline destruction of collagen-containing materials neutralized by different acids are established. © 2013 Pleiades Publishing, Ltd.

This paper presents the results of studies of the impact of chemically modified fullerenes on the properties of ferroelectric liquid crystals. The results of the experiments show that the introduced additives, increasing the rotational viscosity of the liquid crystal blockGoldstonemodeof molecules. Found that the dielectric parameters of the obtained suspension are changed under the influence of light of halogen bulb. © 2014 Sumy State University.

The non-chrome tanning technology for cattle hide was designed. This technology provides to use a "Tansin VP" syntan during pretreatment of hide and main tanning by Chestnut from "Tanin" (Slovenia) or "Chemitan TA" from "Chemipol" (Poland). The application of "Chemitan TA" tanning material makes possible the increase in leather hydrothermal resistance up to 82°C, which is necessary to obtain a chrome-free crust of various applications.

The options for improving energy efficiency of a standard residential building built in 1960s were investigated and analyzed and the structure of the heat losses of the building prior to and after the thermal renovation was determined. Thermal renovation of buildings leads to significant cost savings for space heating. Thus, the implementation of energy-efficient solutions for the analyzed building can lead to the following achievements: replacement of windows by more energy efficient ones leads to a reduction in heating energy consumption by 14,7%; insulation of external walls with bringing resistance to heat transfer to the normative values reduces heat losses by 40,4%; the most quantity of heat energy conservation (76,8%) is achieved by the integrated approach (external building envelope insulation, installation of energy efficient windows, refurbishment of the heating system). Knowing the value of investments in energy saving measures, the payback period can be calculated as well as the optimal energy-saving solution can be determined. The analysis and comparison of different energy saving solutions can be used to identify ways for further upgrading of buildings.
