.Уважаемые коллеги! Представляем вашему вниманию первые результаты исследования наших коллег из Луганска, изучающих респираторную заболеваемость и особенности ее клинических проявлений у детей дошкольного возраста с избыточной массой тела

Optical Spectra of Four Objects Identified with Variable Radio Sources

We obtained optical spectra of four objects identified with variable radio sources. Three objects (0029+0554, 0400+0550, 2245+0500) were found to be quasars with redshifts of 1.314, 0.761, and 1.091. One object (2349+0534) has a continuum spectrum characteristic of BL Lac objects. We analyze spectra of the radio sources in the range 0.97-21.7 GHz for the epoch 1997 and in the range 3.9-11.1 GHz for the epoch 1990, as well as the pattern of variability of their flux densities on time scales of 1.5 and 7 years.Comment: 4 pages, PD

Luminescent properties of Bi-doped polycrystalline KAlCl4

We observed an intensive near-infrared luminescence in Bi-doped KAlCl4 polycrystalline material. Luminescence dependence on the excitation wavelength and temperature of the sample was studied. Our experimental results allow asserting that the luminescence peaked near 1 um belongs solely to Bi+ ion which isomorphically substitutes potassium in the crystal. It was also demonstrated that Bi+ luminescence features strongly depend on the local ion surroundings

Выбор метода диагностики нарушений системы гемокоагуляции у больных в состоянии гиповолемического шока с использованием низкочастотной пьезоэлектрической тромбоэластографии

Гиповолемический шок — тяжелое, остро возникающее состояние, характеризующееся прогрессирующими нарушениями деятельности всех систем жизнеобеспечения организма и требующее неотложной помощи. Наиболее важным для оценки тяжести шоковой реакции и прогноза для пациента является определение степени повреждения системы гемостаза. Цель работы. Определить преимущества комплексной диагностики функционального состояния системы гемокоагуляции с использованием метода низкочастотной пьезоэлектрической тромбоэластографии (НПТЭГ) у больных в состоянии гиповолемического шока по сравнению с традиционными методами диагностики. Материалы и методы. Работа проводилась на базе отделений реанимации и интенсивной терапии ООКБ, отделения реанимации и интенсивной терапии ГКБ № 11. Обследованы пациенты в состоянии гиповолемического шока (25 человек), у которых во время комплексной диагностики состояния гемокоагуляции использовался метод НПТЭГ и проводилась оценка функционального состояния системы гемокоагуляции в динамике.Hypovolemic shock — a severe, acute condition, which is characterized by progressive disorders of all life-support systems of the body and requires emergency care. The most important for assessing the severity of shock reaction and the prognosis for the patient is to determine the extent of damage of hemostasis. Aim. Identify the benefits of integrated diagnostic function of the system hemocoagulation with the use of low-frequency piezoelectric thromboelastography (LPTEG) in patients in a state of hypovolemic shock compared with traditional methods of diagnosis. Materials and methods. The work was carried out at the units of intensive care ORH, resuscitation and intensive therapy department of the Clinical Hospital N 11. There were examined patients under condition of hypovolemic shock (25 patients), which were used the method LPTEG and performed functional evaluation of the system hemocoagulation dynamics

Plasma–liquid interactions: a review and roadmap

Plasma–liquid interactions represent a growing interdisciplinary area of research involving plasma science, fluid dynamics, heat and mass transfer, photolysis, multiphase chemistry and aerosol science. This review provides an assessment of the state-of-the-art of this multidisciplinary area and identifies the key research challenges. The developments in diagnostics, modeling and further extensions of cross section and reaction rate databases that are necessary to address these challenges are discussed. The review focusses on non-equilibrium plasmas

Some features of the structure of the mantle of the Eastern Mediterranean and their geodynamic interpretation

We consider specific velocity anomalies and the corresponding mantle structures of the East Mediterranean-Black Sea-Caspian region. The anomalies are located on latitudinal and longitudinal seismic tomography sections obtained by constructing 3D P-velocity model of Eurasia applying the Taylor approximation method. The depth of the study is of 50—2900 km. The accuracy of determination of the velocity VP is about ± 0.015 km/s. Velocity sections are shown in residual values ΔVP. Physical and mineralogical mantle model of Pushcharovsky was used for the cross sections specification.In the 25—30° E cross sections between latitudes of the 34—48°N high-velocity slabs sinking from the northern edge of the African plate and the southern parts of the East-European plate towards each other are seen. Slabs are connected at a depth of about 600 km in the upper mantle transition zone  in the area of 42—43° N. Below the slabs junction  high-velocity mantle zone thickens and extends to a depth of 1000—1200 km that occurs as a result of slabs relatively high-velocity  material accumulation. From this area down-welling begins which can be traced on latitude sections of 35—45° N as an almost continuous inclined layer of ~1100 km width   and ~ 1900 km length. Down-welling submerges from a depth of 450—550 km at Moesian and Aegean micro-plates area to a depth of 1600—1900 km beneath the East Black Sea, Anatolian micro-plates and the northern part of the Arabian plate. The mechanism of the inclined layer formation is discussed with the involvement of global seismic tomography data, and the numerical simulation performed by L. I. Lobkovsky.In the 42—44° N and 34—36° E sections we trace column type vertical structure, which crosses almost the entire mantle at depths of 50—100 to > 2500 km. In the middle of the column on its axis there is a relatively high-velocity anomaly, which reduces in size and values downward. The shape and structure of the mantle column resembles a "tornado". We consider two possible alternative mechanisms of its formation: a) steep subduction of the West Black Sea micro plate beneath the Central Black Sea Ridge, "wedging" of the mantle and the extension  stresses occurrence  in  border zone I and  middle mantle;  b) rising of the plume from  zone D'',  formation of  extension area in  middle and upper mantle,  lithosphere pulling inward  and  the  subduction zone formation
