We model the overall shape of an accretion disc in a semi-detached binary system in which mass is transfered on to a spinning black hole the spin axis of which is misaligned with the orbital rotation axis. We assume the disc is in a steady state. Its outer regions are subject to differential precession caused by tidal torques of the companion star. These tend to align the outer parts of the dis...
Background and Objective: Extended spectrum beta-lactamases (ESBLs) are defined as enzymes capable of hydrolyzing oxyimino-cephalosporins. Selective pressure of overuse of new antibiotics may be associated with emergence of new types of beta-lactamases. The aim of this study was to identify urinary isolates of CTX-M ESBL-producing Klebsiella pneumoniae and to detect their pattern of antibiotic ...
Recently, result diversification has attracted a lot of attention as a means to improve the quality of results retrieved by user queries. In this paper, we propose a new, intuitive definition of diversity called DisC diversity. A DisC diverse subset of a query result contains objects such that each object in the result is represented by a similar object in the diverse subset and the objects in ...
Background and Objective: Since the preparation of antibacterial materials in dentistry is very noticeable, therefore, we tried to evaluate this effect on Streptococcus mutans by addition of silica nanoparticles to LCGI (light curing glass ionomer). Materials and Methods: In this in vitro study, we had five LCGI experimental groups that contained 0, 0.2, 0.5, 1, and 2% (w/w) of silica nanopa...
Abstract. We present a simple approximate analytical formulae describing relativistic shift of a spectral line, produced by a small bright spot on a thin accretion disc around a nonrotating black hole. For the redshift factor we employ similar approach as Zhang & Bao (1991), improved in terms of Beloborodov’s (2002) approximation for light bending. Another approximation is used also for calcula...
