Quantum Equivalence of Massive Antisymmetric Tensor Field Models in Curved Space

We study the effective actions for massive rank-2 and rank-3 antisymmetric tensor field models in curved space-time. These models are classically equivalent to massive vector field and massive scalar field with minimal coupling to gravity respectively. We prove that effective action for massive rank-2 antisymmetric tensor field is exactly equal to one for massive vector field and effective action for massive rank-3 antisymmetric tensor field is exactly equal to one for massive scalar field. Prove is based on an identity for mass-dependent zeta-functions associated with Laplacians acting on $p$-forms.Comment: 8 pages, REVTeX fil

A theoretical study of the structural phases of Group 5B - 6B metals and their transport properties

In order to predict the stable and metastable phases of the bcc metals in the block of the Periodic Table defined by groups 5B to 6B and periods 4 to 6, as well as the structure dependence of their transport properties, we have performed full potential computations of the total energies per unit cell as a function of the c/a ratio at constant experimental volume. In all cases, a metastable body centered tetragonal (bct) phase was predicted from the calculations. The total energy differences between the calculated stable and metastable phases ranged from 0.09 eV/cell (vanadium) to 0.39 eV/cell (tungsten). The trends in resistivity as a function of structure and atomic number are discussed in terms of a model of electron transport in metals. Theoretical calculations of the electrical resistivity and other transport properties show that bct phases derived from group 5B elements are more conductive than the corresponding bcc phases, while bct phases formed from group 6B elements are less conductive than the corresponding bcc phases. Special attention is paid to the phases of tantalum where we show that the frequently observed beta phase is not a simple tetragonal distortion of bcc tantalum

Paradigmatic and syntagmatic properties of adverbial verbs of motion were analysed. Differences in conveying verbs with explicit and implicit semes of motion were established. Translation on the level of variational correspondences is predominant when rendering verbs with explicit seme; translation on the level of contextual substitutions is typical of verbs with implicit seme

An "in situ" study of study of quenched Ti-Al system samples during heating

The study of the Ti-Al system samples containing up to 10 wt.% Al water quenched from different temperatures in β-phase region, was carried out in situ during heating on X-ray diffractometer. XRD analysis of quenched samples showed the presence of α'-martensite only. After quenching the increase of Al content in alloys displayed the decrease of the lattice parameters «a» and «c» and the rise of «c/a» ratio, since the lattice parameter «c» dropped slightly in contrast with the lattice parameter «a». Furthermore, Thermo-XRD (T-XRD) analysis represented the anisotropy of the coefficient of thermal expansion (CTE). Besides, T-XRD analysis indicated, that «c/a» ratio of samples Ti-0.5 wt.% Al with the least amount of Al revealed the fall of «c/a» ratio and at the same time samples contained 7 and 8 wt.% Al remained practically the same during heating. Whereas, samples Ti-10 wt.% Al with the largest quantity of Al showed the rise of c/a ratio during heating. © 2019 IOP Publishing Ltd. All rights reserved

Structural and magnetic properties of the (001) and (111) surfaces of the half-metal NiMnSb

Using the full potential linearised augmented planewave method we study the electronic and magnetic properties of the (001) and (111) surfaces of the half-metallic Heusler alloy NiMnSb from first-principles. We take into account all possible surface terminations including relaxations of these surfaces. Special attention is paid to the spin-polarization at the Fermi level which governs the spin-injection from such a metal into a semiconductor. In general, these surfaces lose the half-metallic character of the bulk NiMnSb, but for the (111) surfaces this loss is more pronounced. Although structural optimization does not change these features qualitatively, specifically for the (111) surfaces relaxations can compensate much of the spin-polarization at the Fermi surface that has been lost upon formation of the surface.Comment: 18 pages, 8 figure

A long-term regulation assessment of utility tariff in the adopted tarif decisions annual adjustment context

The article provides a detailed assessment of long-term regulation mechanisms under the conditions of adopted tarif decisions annual adjustment. The Concept of tarif regulation mechanisms introduction for a long-term period has been analyzed. The expediency of application of long-term tarif regulation mechanisms and reasons for emerging contradictions in the transition to such regulation have been determined. The descriptive, analytical and comparative methods have been used and legislative base ofRussia analyzed. The article describes the consequences ofthe transition to establishing long-term tariff and provides evidence of emerging ambiguous situations associated with the increase in the burden and possible losses of participants in the process oftarif regulation. The reasons for emerging contradictions in the transition to long-term tarif regulation have been identifid and substantiated. The authors focus on the analysis ofthe developed target model ofsuch regulation, the effctiveness ofwhich is due to the optimization of operating costs by attracting investment in infrastructure development and state of production facilities. It has been proved that the effctiveness of long-term regulation is subject to doubts and ambiguous situations associated with the increase in the burden on regulatory authorities and possible losses ofresource supplying organizations. The consequence ofit may be a serious change in the indicators of forecasts of socio-economic development of the Russian econom

Analysis of the Impact Consequent to the Emergence of Imported Ebola Virus Disease Cases in the Russian Federation

Objective of the study was to forecast the scale of the outbreak that would emerge after arrival of persons infected with Ebola virus into the Russian Federation. Initial data for the prediction were obtained from retrospective analysis of hemorrhagic Ebola fever outbreaks registered within the period of 1976-2014, and the spread of the virus in the Republic of Guinea and Mali in 2014. Delays in the identification of a patient and the lack of compliance with control measures may result in secondary disease in 3-5 persons from among the members of the family and the medical staff. Timely diagnostics and strict observance of safety regulations for treatment of patients with fever of unknown etiology will minimize the number of secondary diseases to a single case or none at all

Forecasting of the After-Effects of A(H7N9) Modelled Outbreak in the Territory of the Russian Federation

Objective of the study is to evaluate economic losses in the consequence of A(H7N9) virus emergence in the territory of the Russian Federation. Materials and methods. Economic damage from induced fatalities has been predicted using DALY index, taking into account the life loss, depending upon the age of the infected persons and associated amount of short-received gross domestic product (GDP). Results and conclusions. Since nowadays there are reported cases of the disease in China, one should expect individual cases of flu among those, arriving in the Russian Federation from this country. Economic loss is forecasted for the outbreak involving infection of two individuals with A(H7N9) virus; the age of the first patient is over 50, and the outcome of his disease will be lethal. Treatment expenses for two patients may come up to 10.9-21.8 thousand rubles, and economic impact from short-received GDP - up to 3900 thousand rubles
