Stress depended changes in activityof gp red blood cells receptors and its correction by therahertz waves at nitric oxide frequency
Kirichuk V.F.,Svistunov S.V.,Andronov E.V.,Ivanov A.N.
Saratov Journal of Medical Scientific Research , 2011,
Abstract: The effect of electromagnetic radiation in the terahertz range frequencies of molecular spectrum of emission and absorption of nitric oxide 150.176–150.664 GHz for the restoration of the impaired carbohydrate component and functional activity glikoproteid receptors of erythrocytes of white rats in a state of acute imm obilization stress. Shown that exposure to electromagnetic waves at these frequencies is the normalization of the increased content of b-D-galactose in the carbohydrate component and the restoration of the impaired activity of the receptors glikoproteid erythrocytes

Frattura ed Integrità Strutturale , 2013,
Abstract: The general regularities of damage healing during the annealing after cold deformation of metal materials are presented in this paper. In categories of damage mechanics the kinetic equations of damage healing during recovery and recrystallization are formulated. Diagrams of damage healing for some metal alloys are presented. The example of use of investigation results for optimization of industrial technology of pipes drawing is presented.
WEEVILS OF THE LARINUS GENERA OF ZAPORIZ`KA OBLAST (COLEOPTERA, CURCULIONIDAE)
Volovnik S.V.
Bìologì?nij Vìsnik Melìtopol?s?kogo Der?avnogo Pedagogì?nogo Universitetu ìmenì Bogdana Hmel?nic?kogo , 2011,
Abstract: Distribution and ecology of weevils of Larinus were investigated. In the vicinity of Zaporiz`ka oblast (Ukraine)some 9 species were found, namely Larinus adspersus, L. canescens, L. jaceae, L. minutus, L. obtusus, L. planus, L.sturnus, L. turbinatus, L. vulpes. Data on number, distribution, feeding, phenology, breeding, preimaginal developmentand parasites are given for each species. It is suggested that Larinus jaceae, L. оbtusus and L. sturnus could be used forweeds biological control.
Effect of annealing temperature on the value of contact resistance of ohmic contacts to InP
Novitskyi S.V.
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature , 2012,
Abstract: It is experimentally confirmed that the temperature dependence of specific contact resistance of ohmic contacts Au—TiB2—Ge—Au—n—n+—n++-InP is described with the current transport model with a high density of dislocations in the contact region of the semiconductor. The samples used in the experiment were obtained at different annealing temperatures.
The estimation of enclosing structures edge zones influence on thermal performance and energy efficiency of buildings (rus)
Korniyenko S.V.
Magazine of Civil Engineering , 2011,
Abstract: One of priority directions in modern building is maintenance of energy efficiency of buildings and constructions. This problem can be realized by perfection of architectural, constructive and technical decisions. The particular interest is represented by an influence estimation of temperature and moisture mode of enclosing structures on a thermal performance and energy efficiency of buildings. The analysis of the data available in the literature has shown absence of effective calculation methods of temperature and moisture mode in edge zones of enclosing structures that complicates the decision of this problem.The purpose of the given work is an estimation of edge zones influence on a thermal performance and energy efficiency of buildings. The design procedure of energy parameters of a building for the heating period, realized in the computer program is developed. The given technique allows settling an invoice power inputs on heating, hot water supply, an electrical supply. Power inputs on heating include conduction heat-losses through an envelope of a building taking into account edge zones, ventilation heat-losses and leakage air (infiltration), internal household thermal emissions, heat-receipt from solar radiation. On an example it is shown that the account of edge zones raises conduction heat-losses through an envelope of a building on 37 %, the expense of thermal energy on building heating on 32 %, and the expense thermal and electric energy on 13 %. Consequently, thermal and moisture mode in edge zones of enclosing structures makes essential impact on building power consumption. Perfection of the constructive decision leads to decrease of transmission heat-losses through an envelope of a building on 29 %, the expense of thermal energy on building heating on 25 %, the expense of thermal and electric energy on 10 %. Thus, perfection of edge zones of enclosing structures has high potential of energy efficiency.
The complex assessment of a thermal performance of the building envelope
S.V. Kornienko
Magazine of Civil Engineering , 2012,
Abstract: The complex assessment of a thermal performance of the envelope on the basis of natural measurements and numerical modeling of the heat and moisture transport in building components was executed. On the basis of natural measurements it was shown that thermal performance qualities of a maintained building do not meet standard requirements. For the purpose of establishment of the reason of low level of a thermal performance numerical modeling of the heat and moisture transport in an external wall according to the computer program developed by the author, by two options — on the basis of the actual and design data was executed. It was shown that results of numerical modeling on the basis of actual data will well be coordinated with natural data that confirms reliability of the results received on the computer program. On the basis of numerical modeling with use of design data it was established that the design solution of external walls corresponded to standard requirements for a thermal performance, and, therefore, deterioration of a thermal performance can be caused by the violations allowed during construction and reconstruction of the building.
High-strength fiber concrete for industrial and civil construction (rus)
Klyuyev S.V.
Magazine of Civil Engineering , 2012,
Abstract: The issue of using steelfiber for dispersed reinforce of fine-grained concrete is considered in the article. Research of steelfiber concrete patterns based on cement and compositional astringent material was held. The fine-grained cement and the binder with low water demand were used as the main binder. It is established that the application of composite binder and high density packing of the grains raises much the durability indicators. Algorithm and program for composition calculation of fine-grained steel fiber concrete based on technogenic sands enriched with Tavolzhan sands, that allow to get more compact packing of elongated pieces are developed. Optimal selection of filling material allowed to receive fiber concrete based on technogenic sand of Kursk Magnetic Anomaly with ultimate compressive strength equalled to 104,8 MPa, and with ultimate flexural strength 23,2 MPa for flexible structures.

Magazine of Civil Engineering , 2011,
Abstract: In article the review of the information on possibilities of use of recuperators of heat is presented for the warm period of year for air-conditioning system. Aim of heat exchanger work in frost-free season is indirect cooling of incoming air before its input into maintainable premises. It is possible if exhaust air is cooled before its input into heat exchanger . In the article the operational principle of air conditioning system with using of adiabatic air cooling is considered. The data concerned system functioning depending on parameters of microclimate in maintainable premises are given.
