Absolute Hodge classes first appear in Deligne’s proof of the Weil conjectures for K3 surfaces in [14] and are explicitly introduced in [16]. The notion of absolute Hodge classes in the singular cohomology of a smooth projective variety stands between that of Hodge classes and classes of algebraic cycles. While it is not known whether absolute Hodge classes are algebraic, their definition is bo...

BACKGROUND We evaluated the combined use of the modified Hodge test (MHT) and carbapenemase inhibition test (CIT) using phenylboronic acid (PBA) and EDTA to detect carbapenemase-producing Enterobacteriaceae (CPE) and metallo-β-lactamase (MBL)-producing Pseudomonas spp. METHODS A total of 49 isolates of CPE (15 Klebsiella pneumoniae carbapenemase [KPC], 5 Guiana extended-spectrum β-lactamase [...

b ackground : one of the main mechanisms of resistance to carbapenems is potential of klebsiella pneumoniae to produce k . pneumoniae carbapenemase (kpc). kpc is an important type of carbapenemase, which can hydrolyze carbapenems and other beta-lactam antibiotics. modified hodge test (mht) and  use  of  boronic  acid  as  a  kpc  inhibitor  are  two  types  of  phenotypic methods, which are use...

The emergence and rapid spread of Multidrug resistant isolates Klebsiella pneumoniae causing nosocomial infections, which require the great afford for treating patients by clinician. Metallo β-lactamase (MBL) producing poses a challenge to routine microbiology laboratories. purpose this study was assess accuracy various phenotypic methods detecting MBL production among K. isolate. current may p...

We show that the usual Hodge conjecture implies the general Hodge conjecture for certain abelian varieties of type III, and use this to deduce the general Hodge conjecture for all powers of certain 4-dimensional abelian varieties of type III. We also show the existence of a Hodge structure M such that M occurs in the cohomology of an abelian variety, but the Tate twist M(1) does not occur in th...

Introduction: Acinetobacter baumannii is one of the major pathogens causing nosocomial infections due to emergence of resistance to various antimicrobial agents. Resistance due to antimicrobial degrading enzymes is now a worldwide problem and a major reason of concern for the treating physicians. Keeping this in mind, the present study was designed to isolate Acinetobacter baumannii and study v...

The Gauß–Manin connection is an extra structure on the de Rham cohomology of any algebraic variety, ∇ : H dR/k −→ Ωk ⊗k H dR/k (its definition will appear below). If one believes the Hodge conjecture then for a given pure Hodge structure H there is at most one connection ∇ such that H is a Hodge substructure of a cohomology group of a smooth projective complex variety with ∇ induced by the Gauß...
