Пьеса Т. Мидлтона и У. Роули «Оборотень» как «трагедия порока»
The article is devoted to the consideration of the motif of “lapse from virtue” based on the example of the heroine of the Renaissance revenge tragedy “The Changeling” (1622) by Thomas Middleton and William Rowley. The article identifies the key scenes of the tragedy, helping to understand the multidimensionality and allusiveness of the heroine. In the context of the relationship of the heroine to other characters in the tragedy, the authors determine and analyse the character metamorphosis and stages of the moral decay of Beatrice-Joanna. Examples of the subversion of the audience’s expectation are given. The authors examine scenes of the tragedy, which help to reveal the motifs of the double and shapeshifting, related to the image of the main character. The system of characters in the play by Middleton and Rowley is considered in the context of the most significant dramatic works of the Elizabethan and Jacobean eras.El artículo está dedicado a la consideración del motivo de la caída con el ejemplo de la imagen de la heroína principal de la sangrienta tragedia renacentista de la venganza de T.

Exclusive semileptonic and nonleptonic decays of the Bc meson
We study exclusive nonleptonic and semileptonic decays of the Bc-meson within
a relativistic constituent quark model previously developed by us. For the
nonleptonic decays we use the factorizing approximation. We update our model
parameters by using new experimental data for the mass and the lifetime of the
Bc meson and the leptonic decay constants of the D-meson. We calculate the
branching ratios for a large set of exclusive nonleptonic and semileptonic
decays of the meson and compare our results with the results of other
studies. As a guide for further experimental exploration we provide explicit
formulas for the full angular decay distributions in the cascade decays Bc^- =>
J/psi(=> l^+l^-) + rho^-(=> pi^- pi^0) and Bc^- => J/psi(=> l^+l^-) +
W^-(off-shell)(=> l^- + nubar).Comment: 19 pages, 2 figure
Two-particle decays of B_c meson into charmonium states
The factorization of hard and soft contributions into the hadronic decays of
B_c meson at large recoils is explored in order to evaluate the decay rates
into the S, P and D-wave charmonia associated with rho and pi. The constraints
of approach applicability and uncertainties of numerical estimates are
discussed. The mode with the J/psi in the final state is evaluated taking into
account the cascade radiative electromagnetic decays of excited P-wave states,
that enlarges the branching ratio by 20-25%.Comment: 13 pages, LaTeX axodraw-style, 1 figure, 2 table
The northeastern Black Sea redox zone: Hydrochemical structure and its temporal variability
Detailed studies of the vertical structure of hydrochemical parameters in the northeastern Black Sea near Gelendzhik are presented and discussed. This work is based on a set of systematic observations carried out in this region during R/V Akvanavt and R/V Ashamba cruises from 1997 to 2005 and also on data from previous studies from 1984 to 1997. The Black Sea region near Gelendzhik is far from the influences of the Bosporus input and Danube River inflow. Therefore, the vertical structure in this region is more stable compared to the western Black Sea and reflects integrated, rather than local, changes of the Black Sea. Seasonal variations in the distribution of chemical parameters at the redox interface are connected to seasonal variations in hydrophysical processes and organic matter production. In winter, maxima of organic phosphorus and urea were absent in the vicinity of the onset of hydrogen sulfide. The concentrations of nitrate were lower in winter than in summer. Winter mixing in the anticyclone eddies led to reduced vertical gradients in the redox layer and to the disappearance of an upper phosphate minimum. Study of the interannual dynamics of oxygen concentrations in the Cold Intermediate Layer and anoxic waters boundary in the density field position revealed climatic-scale changes that may be connected with changes in the North Atlantic Oscillation (NAO) index. © 2006 Elsevier Ltd.

Gender differences in the pharmacological actions of pegylated glucagon-Like peptide-1 on endothelial progenitor cells and angiogenic precursor cells in a combination of metabolic disorders and lung emphysema
In clinical practice, the metabolic syndrome (MetS) is often associated with chronic obstructive pulmonary disease (COPD). Although gender differences in MetS are well documented, little is known about sex-specific differences in the pathogenesis of COPD, especially when combined with MetS. Consequently, it is not clear whether the same treatment regime has comparable efficacy in men and women diagnosed with MetS and COPD. In the present study, using sodium glutamate, lipopolysaccharide, and cigarette smoke extract, we simulated lipid metabolism disorders, obesity, hyperglycemia, and pulmonary emphysema (comorbidity) in male and female C57BL/6 mice. We assessed the gender-specific impact of lipid metabolism disorders and pulmonary emphysema on angiogenic precursor cells (endothelial progenitor cells (EPC), pericytes, vascular smooth muscle cells, cells of the lumen of the nascent vessel), as well as the biological effects of pegylated glucagon-like peptide 1 (pegGLP-1) in this experimental paradigm. Simulation of MetS/COPD comorbidity caused an accumulation of EPC (CD45−CD31+CD34+), pericytes, and vascular smooth muscle cells in the lungs of female mice. In contrast, the number of cells involved in the angiogenesis decreased in the lungs of male animals. PegGLP-1 had a positive effect on lipids and area under the curve (AUC), obesity, and prevented the development of pulmonary emphysema. The severity of these effects was stronger in males than in females. Furthermore, PegGLP-1 stimulated regeneration of pulmonary endothelium. At the same time, PegGLP-1 administration caused a mobilization of EPC (CD45−CD31+CD34+) into the bloodstream in females and migration of precursors of angiogenesis and vascular smooth muscle cells to the lungs in male animals. Gender differences in stimulatory action of pegGLP-1 on CD31+ endothelial lung cells in vitro were not observed. Based on these findings, we postulated that the cellular mechanism of in vivo regeneration of lung epithelium was at least partly gender-specific. Thus, we concluded that a pegGLP-1-based treatment regime for metabolic disorder and COPD should be further developed primarily for male patients

Time Domain Astronomy: Use of Photometric Surveys for Study of Eclipsing Binaries
Долгопериодические затменные двойные — ценный источник данных для расчета звездных масс. Такие объекты имеют достаточное количество как фотометрических, так и спектральных данных для определения их параметров и дальнейшего анализа. Нами реализуется проект по изучению долгопериодических массивных затменных двойных с целью определения масс их компонентов и уточнения соотношения «масса — светимость» для звезд умеренных и больших масс. Мы описываем суть проекта в общих чертах, более подробно останавливаясь на использовании фотометрических обзоров в наших исследованиях. Представлены результаты анализа фотометрических данных исследуемых объектов, а также демонстрируется несколько случаев, когда анализ данных из обзоров позволяет получить значения орбитальных периодов, заметно отличающиеся от известных ранее.Long-period eclipsing binaries are a valuable source of data for calculating stellar masses. Such objects have a sufficient amount of both photometric and spectral data for determining their parameters and further analysis. We are implementing a project to study long-period massive eclipsing binaries in order to determine their component masses and refine the mass-luminosity relation for stars of high and intermediate masses. We describe our project in general terms, focusing in more detail on the use of photometric surveys in our studies. We present the results of photometric data analysis for the objects we study and besides demonstrate several cases when the data analysis makes it possible to obtain values of orbital periods that differ noticeably from those previously known
Leptonic constants of heavy quarkonia in potential approach of NRQCD
We consider a general scheme for calculating the leptonic constant of heavy
quarkonium QQ-bar in the framework of nonrelativistic quantum chromodynamics,
NRQCD, operating as the effective theory of nonrelativistic heavy quarks. We
explore the approach of static potential in QCD, which takes into account both
the evolution of effective charge in the three-loop approximation and the
linearly raising potential term, which provides the quark confinement. The
leptonic constants of bb-bar and cc-bar systems are evaluated by making use of
two-loop anomalous dimension for the current of nonrelativistic quarks, where
the factor for the normalization of matrix element is introduced in order to
preserve the renormalization group invariance of estimates.Comment: 18 pages, 6 eps-figures, discussion and references added, vNRQCD

Mass spectra of doubly heavy Omega_QQ' baryons
We evaluate the masses of baryons composed of two heavy quarks and a strange
quark with account for spin-dependent splittings in the framework of potential
model with the KKO potential motivated by QCD with a three-loop beta-function
for the effective charge consistent with both the perturbative limit at short
distances and linear confinement term at long distances between the quarks. The
factorization of dynamics is supposed and explored in the nonrelativistic
Schroedinger equation for the motion in the system of two heavy quarks
constituting the doubly heavy diquark and the strange quark interaction with
the diquark. The limits of approach, its justification and uncertainties are
discussed. Excited quasistable states are classified by the quantum numbers of
heavy diquark composed by the heavy quarks of the same flavor.Comment: 14 pages, revtex4-file, 3 eps-figures, 5 tables, typos correcte
