The relative linear order of most genes on bacterial chromosomes is not conserved over evolutionary timescales.One explanation is that selection is weak, allowing recombination to randomize gene order by genetic drift.However, most chromosomal rearrangements are deleterious to fitness.In contrast, we propose the hypothesis that rearrangements in ge
In this paper, a co-axial dual-mechanical ports flux-switching permanent magnet (CADMP-FSPM) machine for hybrid electric vehicles (HEVs) is proposed and investigated, which is comprised of two conventional co-axial FSPM machines, namely one high-speed inner rotor machine and one low-speed outer rotor machine and a non-magnetic ring sandwiched in be
Good knowledge of cross section neutron induced reactions on Zr becomes of importance due to the use of zirconium as structural material in reactors, its applicability in neutron dosimetry and the theoretical model testing.Thin Zr foils (0.05 mm thickness, 99.2% purity) were irradiated in the quasi-monoenergetic p-Li neutron fields, the proton beam
Introduction: Aortitis defined as the inflammation of the aortic wall can 330 gph filter pump be due to various diseases including giant cell arteritis (GCA).Aortic involvement in GCA, reported since 1940, is rarely described.The main objective of this study was to analyse the epidemiological, clinical, radiological and evolutionary characteristics
