A preliminary analysis of fields around 20 mainly radio– quiet QSOs (RQQs) at intermediate redshift is summarized. We find overdensities of faint sources around 50% of our observed QSOs suggesting that they are located in groups or even clusters of galaxies.

Цель исследования. Определить роль различных методов поддержки, таких как энтеральное зондовое и полное паренте: ральное питание в разных фазах течения острого панкреатита (ОП). Материал и методы. У 774 больных с ОП (средний возраст — 45,3±4,7 лет) проведен сравнительный анализ влияния различных способов нутритивной поддержки на секре: торную активность поджелудочной железы (ПЖ) и течение ОП. К...

tory embarrassment or collapse, which in clinical terms is represented most obviously by a reduction in the blood-pressure. There are a number of causes of that state, that is, it is not a definite clinical entity, it is only a train of symptoms, and it is essential for a reception officer to sort out the cases rather than merely to regard transfusion as efficacious for the treatment of every o...

We consider the future dynamics of a transient phantom dominated phase of the universe in LQC and in the RS braneworld, which both have a non-standard Friedmann equation. We find that for a certain class of potentials, the Hubble parameter oscillates with simple harmonic motion in the LQC case and therefore avoids any future singularity. For more general potentials we find that damping effects ...

In this paper a gas turbine power plant including air preheater (recuperator), heat recovery steam generator and air cooler system was modeled. Eight parameters were selected as the design variables.  Fast and elitist non-dominated sorting genetic algorithm (NSGA-II) was applied (to maximize the exergy efficiency and to minimize the total cost rate) for the mentioned cogeneration system. Th...

Introduction: Radiation effects induced in non-irradiated cells are termed radiation- induced bystander effects (RIBE). The present study intends to examine the RIBE response of QU-DB bystander cells to first, second and third radiation fractions and compare their cumulative outcome with an equal, single acute dose.   Materials and Methods: This experimental ...
