development and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولCarbapenemase-producing Enterobacteriaceae.
Carbapenemase-producing Enterobacteriaceae (CPE) were almost nonexistent up to the 1990s, but are today encountered routinely in hospitals and other healthcare facilities in many countries including the United States. KPC-producing Klebsiella pneumoniae was the first to emerge and spread globally and is endemic in the United States, Israel, Greece, and Italy. Recently, NDM-producing Enterobacte...
متن کاملDissemination of carbapenemase-producing Enterobacteriaceae
During the last decade, Gram-negative clinical isolates, including Enterobacteriaceae, Pseudomonas spp. and Acinetobacter spp. with decreased susceptibility to carbapenems, have been increasingly reported in Europe. Carbapenem resistance in Enterobacteriaceae may be related either to the association of a decrease in bacterial outer-membrane permeability with overexpression of b-lactamases posse...
متن کاملGenomic islands are dynamic, ancient integrative elements in bacterial evolution.
Acquisition of genomic islands plays a central part in bacterial evolution as a mechanism of diversification and adaptation. Genomic islands are non-self-mobilizing integrative and excisive elements that encode diverse functional characteristics but all contain a recombination module comprised of an integrase, associated attachment sites and, in some cases, a recombination directionality factor...
متن کاملCarbapenemase-producing Enterobacteriaceae, U.S. Rivers
Our study was initiated by previous isolation of 30 imipenem-resistant, gram-negative rods from 7 of 16 U.S. rivers sampled from 1999 to 2001. Imipenem hydrolysis was detected in 22 of those isolates identified as Enterobacter asburiae. Random amplified polymorphism DNA analysis showed that these E. asburiae isolates were genetically indistinguishable. An identical clavulanic acid-inhibited bet...
