introduction: extended spectrum beta-lactamase (esbl) producing escherichia coli generate a major problem for clinical therapeutics and epidemiological study. the incidence of esbl producing strains among clinical isolates has been steadily increasing during the past few years, and remains an important cause of failure of therapy with cephalosporins. the aim of this study was to determine the a...

conclusions the most effected parts in asd are lateral connections of hmasd. two-sided connections which are completely symmetric become more active, and cause extra synchronization. on the other hand, due to special characteristic of two-sided connections and their ability to simulate the same phased dynamics, they cause unnatural asymmetry in children’s eeg signal. these results are consisten...

abstract background: accurate methods of radiation therapy dose calculation. there are different monte carlo codesfor simulation of photons, electrons and the coupled transport of electrons and photons. mcnpis a general purpose monte carlo code that can be used for electron, photon and coupledphoton-electron transport.monte carlo simulation of radiation transport is considered to be one of the ...

different methods for detecting broken bars in induction motors can be found in literature. many of these methods are based on evaluating special frequency magnitudes in machine signals spectrums. current, power, flux, etc are among these signals. frequencies related to broken rotor fault depend on slip. in industrial environment due to some phenomena - such as load oscillation, other faults an...

background and objective: nanoscopic life forms called nanobacteria or calcifying nanoparticles (cnp) are unconventional agents. these novel organisms are very small (0.1 to 0.5 microns) and possess unusual properties such as high resistance to heat and routine antimicrobial agents. nanobacteria are 100 times smaller than bacteria and protected by a shell of apatite, so they could be as candida...

background: neutropenic patients are vulnerable to a wide spectrum of infectious agents. the aim of this study was to determine the current frequency of bacterial infections in patients with nosocomial fever and neutropenia. methods: in a retrospective study, the neutropenic patients’ specimens with nosocomial fever were cultured on blood and macconkey agar plates and evaluated at microbiology ...

background: alcohol is a potent teratogen and alcohol use in pregnancy and the periconception period can cause many complications in mother, fetus and neonate.  discussion: alcohol in the mother's blood passes through the placenta to the baby through the umbilical cord. drinking alcohol during pregnancy can cause miscarriage, stillbirth, and a range of lifelong disorders. alcohol-related birth ...

let $r$ be a commutative ring. in this paper, by using algebraic properties of $r$, we study the hase digraph of prime ideals of $r$.

It is well known that the real spectrum of any commutative unital ring, and ℓ-spectrum Abelian lattice-ordered group with order-unit, are all completely normal spectral spaces. We complete existing list containments non-containments between associated spaces their subspaces, by proving following results: (1) Every can be embedded, as a subspace, into some ℓ-spectrum. (2) Not every an (3) A subs...

We define a new type of spectrum, called δ-approximate spectrum, of an element a in a complex unital Banach algebra A and show that the δ-approximate spectrum σ_δ (a) of a is compact. The relation between the δ-approximate spectrum and the usual spectrum is investigated. Also an analogue of the classical Gleason-Kahane-Zelazko theorem is established: For each ε>0, there is δ>0 such that if ϕ is...
