Экологическая обусловленность применения спелеоклиматотерапии как метода профилактики бронхолегочных заболеваний

The article concerns some ecological aspects of therapeutic features of speleotherapy. The objective of our study was to investigate the therapeutic activity of speleotherapy for respiratory disorders according to it's ecological aspects. The results of including speleotherapy into the curative and prophylactic complex in the central-chernozyom region showed the decrease of incidence of respiratory pathology in people, who underwent the course of speleotherapy. The obtained data indicated, that speleotherapy was supposed to be used as a component of prophylactics complex in treatment for broncho-respiratory complex.В статье представлены экологические аспекты лечебных свойств спелеоклиматотерапии. Целью исследования послужило изучение терапевтических свойств спелеоклимата в отношении респираторной патологии в связи с экологическими особенностями данного метода. Результаты внедрения спелеоклиматотерапии в комплекс лечебно-профилактических мероприятий в ЛПУ центрально-черноземного региона демонстрируют снижение частоты бронхолегочных заболеваний, а также обострения хронической респираторной патологии у лиц, прошедших курс спелеоклиматотерапии. Полученные результаты позволяют рекомендовать более широкое внедрение спелеоклиматотерапии в качестве компонента комплексной профилактики бронхолегочных заболеваний

7 GHz pulsed magnicon amplifier

The work on creation of high-power microwave amplifiers with circular deflection of an electron beam has been carried out at INP since 1967. In the latest set of experiments on 7 GHz magnicon almost all design parameters have been achieved: the output power of 55 MW, efficiency of 56 %, and gain of 72 dB. Experimental data are in an excellent agreement with simulation results obtained by the special magnicon computer codes. Achieved results allow us to consider a magnicon as an alternative power source for linear colliders applications

Two-loop Anomalous Dimensions of Heavy Baryon Currents in Heavy Quark Effective Theory

We present results on the two-loop anomalous dimensions of the heavy baryon HQET currents $J=(q^TC\Gamma\tau q)\Gamma'Q$ with arbitrary Dirac matrices $\Gamma$ and $\Gamma'$. From our general result we obtain the two-loop anomalous dimensions for currents with quantum numbers of the ground state heavy baryons $\Lambda_Q$, $\Sigma_Q$ and $\Sigma_Q^*$. As a by-product of our calculation and as an additional check we rederive the known two-loop anomalous dimensions of mesonic scalar, pseudoscalar, vector, axial vector and tensor currents $(J=\bar q\Gamma q)$ in massless QCD as well as in HQET.Comment: 21 pages, LaTeX, 2 figures are included in PostScript forma

An Analysis of Diagonal and Non-diagonal QCD Sum Rules for Heavy Baryons at Next-to-Leading Order in \alpha_S

We consider diagonal and non-diagonal QCD sum rules for the ground state heavy baryons to leading order in $1/m_Q$ and at next-to-leading order in $\alpha_S$. In the non-diagonal case we evaluate the eight different two-loop diagrams which determine the perturbative $\alpha_S$-corrections to the Wilson coefficient of the quark condensate in the Operator Product Expansion. The QCD corrections to the non-diagonal sum rules are moderate compared to the QCD corrections in the diagonal case. We also consider constituent type sum rules using constituent type interpolating currents. The obtained results are in reasonable agreement with the corresponding results obtained in the diagonal case. As central values for the bound state energies we find $m(\Lambda_Q)-m_Q = 760 MeV$ and $m(\Sigma_Q)-m_Q = 940 MeV$. The central values for the residues are given by $F(\Lambda_Q) = 0.030 GeV^3$ and $F(\Sigma_Q) = 0.038 GeV^3$.Comment: 17 pages, LaTeX, 8 figures are included in PostScript forma

PSR J1119-6127 and the X-ray Emission from High Magnetic Field Radio Pulsars

The existence of radio pulsars having inferred magnetic elds in the magnetar regime suggests that possible transition objects could be found in the radio pulsar population. The discovery of such an object would contribute greatly to our understanding of neutron star physics. Here we report on unusual X-ray emission detected from the radio pulsar PSR J1119-6127 using XMM-Newton. The pulsar has a characteristic age of 1,700 yrs and inferred surface dipole magnetic eld strength of 4.1x10^13 G. In the 0.5-2.0 keV range, the emission shows a single, narrow pulse with an unusually high pulsed fraction of ~70%. No pulsations are detected in the 2.0-10.0 keV range, where we derive an upper limit at the 99% level for the pulsed fraction of 28%. The pulsed emission is well described by a thermal blackbody model with a high temperature of 2.4x10^6 K. While no unambiguous signature of magnetar-like emission has been found in high-magnetic-eld radio pulsars, the X-ray characteristics of PSR J1119-6127 require alternate models from those of conventional thermal emission from neutron stars. In addition, PSR J1119-6127 is now the radio pulsar with the smallest characteristic age from which thermal X-ray emission has been detected

Baikal-GVD

We present the status of the Gigaton Volume Detector in Lake Baikal (Baikal-GVD) designed for the detection of high energy neutrinos of astrophysical origin. The telescope consists of functionally independent clusters, sub-arrays of optical modules (OMs), which are connected to shore by individual electro-optical cables. During 2015 the GVD demonstration cluster, comprising 192 OMs, has been successfully operated in Lake Baikal. In 2016 this array was upgraded to baseline configuration of GVD cluster with 288 OMs arranged on eight vertical strings. Thus the instrumented water volume has been increased up to about 5.9 Mtons. The array was commissioned in early April 2016 and takes data since then. We describe the configuration and design of the 2016 array. Preliminary results obtained with data recorded in 2015 are also discussed

Structure-property relationships in polymer nanocomposites based on cross-linked polyurethanes and carbon nanotubes

The results of experimental and calculation researches of structure, electric and thermophysical characteristics of polymer nanocomposites based on cross-linked polyurethanes (CPU) and carbon nanotubes (CNT) are presented. It is shown that the CPU-CNT systems have a structure with two fractal levels. It is discovered that the CPU-CNT nanocomposites show a percolation behavior, and the concentration dependence of electric- and heat-conductivity are well described in the framework of scaling approach. It is shown that a percolation threshold for these systems is 0.6 %. Formation of the percolation net from CNT, when the content of nanotubes is 0.6 %, was confirmed by the optical microscopy results
