Introduction: Clindamycin is considered an useful alternate drug in penicillin-allergic patients in the treatment of skin & soft tissue infections caused by Staphylococcus aureus. Staphylococcus spp. can be resistant to erythromycin through either erm or msr A genes. Strains with erm-mediated erythromycin resistance may possess inducible clindamycin resistance but may appear susceptible to clin...

The disc covering problem asks to cover a set of points on the plane with a minimum number of fix-sized discs. We develop an O(n(log n)(log log n)) deterministic time 2.8334-approximation algorithm for this problem. Previous approximation algorithms [7, 3, 6], when used to achieve the same approximation ratio for the disc covering problem, will have much higher time complexity than our algorithms.

AmpC β-lactamases are cephalosporinases that hydrolyze cephamycins as well as other extended-spectrum cephalosporins and are poorly inhibited by clavulanic acid. Although reported with increasing frequency, the true rate of occurrence of AmpC β-lactamases in different organisms, including members of Enterobacteriaceae, remains unknown. The present study was designed to determine the occurrence ...

We show how the local approximation of astrophysical discs, which is basis for well known model shearing box, can be used to study many aspects dynamics warped discs. In model, inclination orbit a test particle with respect reference corresponds vertical oscillation at orbital frequency. Warping disc locally axisymmetric corrugation midplane that oscillates vertically frequency, while evolution...

The fuzzy disc is a matrix approximation of the functions on a disc which preserves rotational symmetry. In this paper we introduce a basis for the algebra of functions on the fuzzy disc in terms of the eigenfunctions of a properly defined fuzzy Laplacian. In the commutative limit they tend to the eigenfunctions of the ordinary Laplacian on the disc, i.e. Bessel functions of the first kind, thu...

PURPOSE The present study was undertaken to detect metallo-beta-lactamase (MBL) in nosocomial isolates of Pseudomonas aeruginosa by four different phenotypic methods. METHODS Ninety-one consecutive P. aeruginosa isolates were subjected to susceptibility testing by disc-diffusion assay and Vitek 2. Imipenem resistance was determined by three different methods (disc-diffusion, Vitek 2 and E tes...

We test approximate approaches to solving a neutrino transport problem that presents itself in the analysis of some accretion-disk models. Approximation # 1 consists of replacing the full, angulardependent, distribution function by a two-stream simulation, where the streams are respectively outwardly and inwardly directed, with angles cos θ = ±1/ √ 3 to the vertical. In this approximation the f...
