- ДокументEnrichment of georgian cheese with biologically active components of Saperavi(2018) Maisuradze, G.Food quality can be considered as one of the most important and essential issue in every epoch. Nutrient substances play a prominent role in supplying the human body/organism with special biologically active components. According to balanced feeding theory for normal functioning in the physiological framework of the human body, not only proteins, fats and carbohydrates are necessary, also there are other substances such as irreplaceable amino acids, vitamins, minerals and other biologically active natural substances. Increasing food quality of product and food optimization natural and accessible way is depended on combination of animal and vegetable raw materials. It has been proved that with merge of animal and vegetable components we make enrichment of products with biologically active substances. Dairy products are considered as one of the perspective raw materials for making multicomponent product that can include dietary, medicinal and prophylactic purposes. The paper represents the discussion and results of the experiment about some phenols which are transferred into the cheese after aging in Saperavi wine and the cheese which prepared in Saperavi wine and then aging in the same wine. On the base of experiment the following results have been uncovered – the common phenols and anthocyanin’s rate in the cheese aged in Saperavi wine and define the reliability of mentioned substances as biologically active, and a real source for the formation of medicinal and prophylactic value.

- ДокументDevelopment of a graphical user interface for egg quality assessment based on a computer vision system(2018) Zhelezarova, P.; Paskova, N.The paper presents a developed graphical user interface for recognizing defective eggs in the MATLAB environment, based on computer vision. The interface is modular, which allows for the upgrade of the procedures and algorithms that are used. The accuracy of recognition for the four main qualitative groups of eggs was tested. Accuracy ranges is from 0.6 to 2.1%.

- ДокументA novel two-stage ejector refrigerator with mixed refrigerants(2018) Wang, Xuehui; Zhou, Yifan; Pan, Yini; Chen, GuangmingThe energy consumption is ramping up in recent decades. Therefore, it was very important to recover and utilize the low-grade energy, such as the solar energy, the geothermal energy and low-temperature waste heat discharged to the environment. The ejector system has a good prospect in this area due to its obvious advantages :simple structure, without moving part and available for heat sources in different temperature levels, as well as long life-span. Nevertheless, the coefficient of performance of the ejector system is relatively low, so the technology to optimize the ejector refrigeration cycle has been hot topics. In this report, a novel two-stage ejector system with mixed refrigerants was proposed to improve the efficiency of the ejector system. A separator was used to divide the working fluid to high boiling point fluid and low boiling point fluid. The performance of the new system was calculated and compared with other ejector systems. It was suggested that the novel system had a higher COP than other ejector refrigeration systems. Furthermore, it could operate at a higher condensation temperature. When the condensation temperature continued to rise above 50℃, the new system could still be reliable and the COP was about 0.1

- ДокументThe prospects of application the generators with permanent magnets for small wind power plants(2018) Sergienko, I.The paper assesses the prospects for the use of renewable energy sources (RES) in Ukraine. In particular, wind energy is considered as a factor of reducing the environmental load from the activities of the country's fuel and energy complex. The paper assesses the prospects for the use of renewable energy sources (RES) in Ukraine. In particular, wind energy is considered as a factor of reducing the environmental load from the activities of the country's fuel and energy complex. The area is allocated to the use of small wind power plants (WPP) as sources of power supply for autonomous electric receivers up to 50-100 kW. A comparison was made for the recommended generators of such wind turbines. The use of synchronous alternating current generators with excitation from permanent magnets with high magnetic properties based on NdFeB and SmCo was proposed. In work the technical and economic analysis of offered magnets and the analysis of design features of generators with a magnetoelectric are executed.
- ДокументModelling of photovoltaic solar cells by modifying fins configuration of the air-cooled heat sinks for power generation(2018) Siarova, А.The present research focus on three configurations ways of the cooling air-duct of a monocrystalline photovoltaic (PV) cell. The spacing within the fins, the fin’s thickness, and the height of fins were examined to find out which is the best system configuration capable to decrease the PV cell temperature and thus, increase its efficiency. Economical approach was used to unbalance the decision where there’s no much difference in terms of the achieved efficiency. Lastly, models to predict the PV panel temperature were investigated and presented to provide a basic understanding of the change magnitude produced by these three configurations.

- ДокументTechnological properties and quality indicators of hulled wheat(2018) Zhyhunova, H.Among the many types of wheat, the most common today is the modern cultivated wheat T.aestivum L., which is known as common wheat or bread wheat, but exist ancient types of wheat: diploid – T. monococcum L. (AA); tetraploid – emmer (AABB), as well as hexaploid – spelt (AABBDD). In this research work, the currently used species of wheat, this is part of the group of hulled species – spelt and emmer wheat. Hulled wheat considered being a crop with high nutritional value, which determines its relevance and using in Ukraine. Hulled wheat in comparison with common wheat contains practically all the nutrients that are necessary to the human body. The purpose of the research is to substantiate the directions of further processing of spelt and emmer on the basis of comparison of their physicotechnological and chemical composition with ordinary hard wheat. In this work was done following tasks: 1. Chemical composition of macronutrients of investigated samples of wheat; 2. Physico-technological properties of the studied samples; 3. Flour and cereal indices of investigated samples of wheat; 4. Physico-chemical properties of investigated wheat samples. The results of the research showed the difference in the physical and mechanical properties of the spelta and emmer compared to the common wheat (Kuyalnik). The work consists of 6 sections, outlined on 18 pages, includes 6 tables, the list of references includes 18 titles.
