Lipids in estimation of tuberculosis treatment various modes toxic action at the patients with hiv-infection

Russian Federation concerns to number of the countries with high worsening tuberculosis epidemiological situation on HIV-infection. At the patients with HIV-infection of tuberculosis mortality reaches 43-89 %. The tuberculosis morbility at the patients with HIV-infection were at 21-37 of time is higher, than at the people without HIV-infection, and in separate researches speak about risk of tuberculosis development at early stages of HIV-infection in 113 times. The purpose of work - to determine importance of blood lipid changes in an estimation of toxic action of various modes of tuberculosis treatment at the patients with HIV-infection. Totally 100 persons with a tuberculosis and HIV infection with a various mode of tuberculosis treatment were surveyed. The parameters of the routine biochemical tests and relative contents total lipids and phospholipids were investigated. The analysis of biochemical tests routine parameters has found out absence of level increase total bilirubint, creatinine, alaninaminotransferase (АLT), aspartasaminitransfarase (AST) activity. However there is increased level of activity alkaline phosphotase (173,2 ЕД/л) and lactatedehydrogenese (379,4 ЕД/л) at the patients with the first mode tuberculosis chemotherapy. The first standard mode of tuberculosis treatment was rendered more expressed toxic effect on the patients, which was shown more by high level fry fatty acid, trigliceriges and low level of free cholesterol and ethers of cholesterol were established. The increase of a phosphstidiletanolamine level can be considered as not only the proved marker of the first standard regime toxic tuberculosis treatment action, but also efficiency of application antiretroviral therapy at the patients with tuberculosis/HIV-infectio

The numerical simulation of ceramic composites failure at axial compression

On the basis of the developed model of quasibrittle medium the brittle and quasibrittle failure ofcomposite ceramic materials with zirconium dioxide matrix and various percentage of hardening particles ofcorundum are studied numerically. The theory of the damaged media is applied in the calculations. It is shownthat failure process educes in 2 stages - a relatively slow quasistationary phase of accumulation of inelasticdeformations and damages in all hierarchy of scales and superfast catastrophic phase - a blow-up regime whenthe failure process reaches the macro-scale and there is a macro-crack formation. The failure process in theproposed model assumes to be completed when the damage function reaches its maximum value and thestrength of the composite evolve to zero

Silicon carbide for solar energy

Paper presented to the 3rd Southern African Solar Energy Conference, South Africa, 11-13 May, 2015.SiC is a wide-bandgap semiconductor that possesses quite a number of interesting properties and is promising for application in power, high-temperature, and radiation hard electronics. Several areas can be distinguished in which SiC is also a promising material for solar power engineering. SiC high temperature power devices and UV detectors can be used at solar energy stations and also SiC can be used as a substrate for growth III-N materials and graphene. New results obtained at the Ioffe Institute, Nitride Crystals Co and National Research University of Information Technologies, Mechanics and Optics in all the above areas of research will be presented in the reportcf201

Generalized Farey trees, transfer Operators and phase transitions

We consider a family of Markov maps on the unit interval, interpolating between the tent map and the Farey map. The latter map is not uniformly expanding. Each map being composed of two fractional linear transformations, the family generalizes many particular properties which for the case of the Farey map have been successfully exploited in number theory. We analyze the dynamics through the spectral analysis of generalized transfer operators. Application of the thermodynamic formalism to the family reveals first and second order phase transitions and unusual properties like positivity of the interaction function.Comment: 39 pages, 10 figure

MODELLING OF ELASTIC-PLASTIC DEFORMATION OF POLYCRYSTALLINE AND COMPOSITE MATERIALS UNDER LOADING

The process of deformation development in a polycrystal with pain interaction is modelled in frames of flat two-dimensional elastic-plastic flow of the media with structure. The processes of a possible fragmentation and a grain boundary segregation influence on the plastic deformations development are considered. The influence of distribution of a work under non-elastic deformation on material structure change and average value of mechanical parameters determination is analising in the presented calculations of deformation of a composite material with damping matrix
