Pharmacoeconomic evaluation of dabigatran vs warfarin in cardiovascular events prevention in patients with non-valvular atrial fibrillation
Yu.B. Belousov,V.Yu. Mareev,I.S. Yavelov,D.Yu.Belousov
Rational Pharmacotherapy in Cardiology , 2012,
Abstract: According to recent guidelines, oral dabigatran etexilate is indicated for stroke and systemic embolism prevention in patients with atrial fibrillation (AF).Aim. Based on the RE-LY study to evaluate the cost-effectiveness of dabigatran etexilate versus warfarin prescribed in “real-world” settings from a Russian payer perspective.Material and methods. Markov model simulated AF patients at moderate to high risk of stroke while tracking clinical events and resulting functional disability. Acute event costs and resulting long-term follow-up costs incurred by disabled stroke survivors were calculated using general tariff agreement of Russian obligatory health insurance system and official national statistics. Clinical events, summarized as events per 100 patient-years, expected life years, total costs, and incremental cost effectiveness ratios (ICER) were calculated.Results. Over a lifetime, dabigatran etexilate treated patients experienced fewer intracranial haemorrhages and fewer ischaemic strokes. ICER of dabigatran etexilate was 461,602 roubles per one additional life year versus “real-world” warfarin.Conclusion. This study demonstrates that dabigatran etexilate is a cost-effective alternative to current care for the prevention of stroke and systemic embolism among Russian patients with AF.
K 3He and K 4He interactions at low energies
Grishina V.Yu.
EPJ Web of Conferences , 2010, DOI: 10.1051/epjconf/20100303022
Abstract: Using the multiple scattering approach (MSA) in the xed center approximation we calculated the K 4He and K 3He scattering lengths. The K 4He scattering length is also analyzed in the optical potential model. Within the MSA the K 3He nal state interaction factor was also calculated. It is found that the K 3He mass spectrum for the pd → 3HeK+ K reaction is expected to be in uenced by the K 3He FSI e ect.

Journal of Nano- and Electronic Physics , 2011,
Abstract: Using of the likelihood methods for scintillation coordinate calculation in the gamma-camera detector is considered in the paper. Using of the composite goodness-of-fit criteria is proposed for increasing of the methods robustness. The influence of the used goodness-of-fit criteria to intrinsic gamma-camera properties is studied by the simulation methods.

Materials with a high on-off resistance ratio could become the basis for resistive random-access memory (RRAM). It is assumed that one of RRAM types can be based on hybrid organic-inorganic systems, while particular attention is focused on hybrid systems consisting of metal nanoparticles (NP) embedded in organic matrix (OM). In this investigation we created and studied the hybrid organic-inorganic systems made of metal (Ag) nanoparticles embedded in organic semiconductor material CuPc. The LEED patterns and NEXAFS data demonstrate that the CuPc films deposited on Au(001) substrate are highly ordered and molecular planes lie parallel to the gold surface. The metal atoms were deposited on the outer surface of the organic molecular film and self-assembled into nanoparticles due to surface and bulk diffusion. The properties of nano-composite materials seem to be significantly dependent on the microstructure, i.e. the size, concentration, bulk- and size-distribution of nanoparticles; therefore we have studied by high resolution transmission electron microscopy the evolution of morphology of nano-composite films as a function of nominal metal deposition. The filled and empty electronic states of the hybrid organic-inorganic systems, energy level alignment at interfaces formed between metal nanoparticles and the organic semiconductor CuPc as well as the chemical interaction at the NP/OM interface were studied by UPS, XPS and NEXAFS methods.


The consolidation of a powder material in conditions of combined influence of different technological factors
Dorofeyev V.Yu.,Dorofeyev YU.G.
Science of Sintering , 2003, DOI: 10.2298/sos0301013d
Abstract: In the present paper the problems, connected with the formation of a powder material and its surface layers in conditions of chemical thermal treatment and impregnation with melt, combined with the use of mechanical loads at different process stages are examined. The new results of liquid phase influence on compaction of powder preforms, subjected to impregnation, are obtained. The presence of a liquid phase in preform surface layers can also be connected with the change of the materials chemical composition as the result of boronizing, siliconizing or other kinds of chemical thermal treatment.
Numerical analysis of the effect of freezing ground in the laying zone pads on heat loss of channelless pipelines laid out without canals
V.Yu. Polovnikov,V.A. Huzeev
Magazine of Civil Engineering , 2013,
Abstract: The results of mathematical modeling of heating mains laid out without canals, as well as numerical analysis of their heat losses in the presence of ground freezing in the area of installation are presented. The laws of heat transfer in the system and the factors influencing the intensification of heat losses are established. It was revealed that the regulatory calculation method of pipelines’ heat losses gives overestimated values. It was found that the heat losses of pipelines subject to ground freezing in the laying zone rise by 1.65–5.04%. The deviation between the heat losses of pipelines is about 21–27%, taking into account the freezing ground in the laying zone and heat losses, calculated according to standard methods. That indicates the need to adjust the regulatory procedure. These results suggest promising application of the developed approach to the analysis of thermal conditions and heat loss of heating mains laid out without canals in conditions of freezing ground in the laying zone and the possibility of its use in the creation of energy efficient heat transfer system.
Heat loss of underground channel heat pipelines with strained thermal insulation layer, taking into account radiative heat transfer in the cavity of the channel

Magazine of Civil Engineering , 2012,
Abstract: The weakest places of centralized heating systems are the pipelines. Heat pipe network systems, built in the USSR, are characterized by low reliability, high damage possibility and large heat losses. The main reasons for the heat losses growth are moisture, deformation and breakage of the thermal insulation layer.The purpose of this paper is to assess the extent of underground channel pipelines with strained thermal insulation layer heat losses, taking into account radiative heat transfer in the cavity of the channel.During the work the numerical analysis of thermal insulation layer deformation effect and radiation heat transfer in the cavity of the channel influence on thermal conditions and heat losses of underground channel pipelines was achieved. On the basis of these results the perspective of the developed model and numerical analysis techniques for the extent of pipelines with deformed thermal insulation heat losses evaluation was determined.
