DEVICE FOR DIAGNOSTICS AND MONITORING OF POWER TRANSFORMERS IN THE WORKING MODE

Posted in 2017, ENGINEERING, Issue № 7(61) July 2017 | 0 comments

At present, timely diagnostics is a necessary condition for reliable operation of various electrical devices. Thus, it is necessary to control such quantities as short-circuit resistance (SCR) and leakage inductance for power transformers of high power, for example, in transformer substations. Their control over the whole lifetime allows detecting possible damage to the transformer after emergency situations, because at the time of short circuit protective devices do not instantaneously disconnect the transformer and its shock windings briefly flow shock currents subjecting the transformer elements to large mechanical overloads, which can lead to the displacement or deformation of windings and core.

QUALITY MANAGEMENT OF URBAN ENVIRONMENT: TWO APPROACHES TO WATER OBJECTS REHABILITATION

Posted in 2017, Issue № 7(61) July 2017, SCIENCES ABOUT THE EARTH | 0 comments

Such natural-anthropogenic objects as softscape and water bodies are an integral part of the urban environment. They make a significant contribution to improving the quality of the urban environment. At present, two approaches are used to manage the quality of urban water bodies in our country – linear and cyclical (planning – implementation – control – action). The ecological performance of a number of rehabilitation projects for water bodies has been analyzed. They can be assessed both by environmental and social indicators (quality of recreational and cultural-historical landscape). The importance of using measurable quality indicators for the components of the urban environment including the water body for the planning phase is shown in the article. The stage of implementation, depending on the environmental goals and objectives set, can be based on ecological rehabilitation, manipulation, restoration and conservation. Control is carried out in the form of comparison with the environmental quality standards, as well as with the help of scores. Examples of successful rehabilitation projects for urban water bodies are analyzed, using both linear and cyclic models of quality management.

INTENSIFICATION OF THE PROCESS OF OBTAINING HOMOGENEOUS HIGH-CONCENTRATED MIXTURES WITH THE LIQUID PHASE IN THE TECHNOLOGY OF BREAD PRODUCTION

Posted in 2017, ENGINEERING, Issue № 7(61) July 2017 | 0 comments

The following article is devoted to the study of the water mechanical activation effect and its diluted solutions with starch and gluten on the process of mixing with flour, the formation of the structure and rheological characteristics of dough and baked bread. We conducted the analysis of the experimental data and assumptions related to the use of mechanical activation of liquid components in the technological processes of the bakery production. Based on the results of the experiments, it was determined that specific work and kneading time can be reduced by at least two times with the help of mechanically activated liquid components. Thus, having previously expended energy for mechanical activation of water and solutions, we obtain a double economy when kneading dough. The use of mechanic activation makes significant changes in the quality of finished products. So, the use of active water is advisable in the production of such products as “Cut Long Loaf,” the main quality of which is its high elasticity and fine-porosity. The use of such a method of preparing liquid components for production will reduce the number of technological processes of structure formation and, accordingly, of equipment. This will enable the reduction of the production space and cost while keeping the quality of finished products. The use of diluted mechanically activated solutions of gluten and starch will improve the quality of bread.

PHASICITY OF HEMOSTATIC SHIFTS AS A RESULT OF INSUFFICIENCY OR ABUNDANCE OF VITAMIN C

Posted in 2017, Issue № 7(61) July 2017, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The experiment on animals that do not synthesize vitamin C has shown that the lack of vitamin C in the diet entails a decrease in platelet coagulo-activity and phase changes in the intensity of blood coagulo-ability. Vitamin C in doses, which form part of the daily requirement, limits detected changes and postpones them in time. It becomes more noticeable when the dose is higher. Excess of vitamin C does not only limit, but also prevents these shifts. It is desirable to apply vitamin C in high doses or in therapeutic doses for a long time in case of diseases with a tendency to thrombophilia or bleeding, preferably with the control of plasma levels of markers of intravascular coagulation.
