Let $R$ be a reversible ring which is $alpha$-compatible for an endomorphism $alpha$ of $R$ and $f(X)=a_0+a_1X+cdots+a_nX^n$ be a nonzero skew polynomial in $R[X;alpha]$. It is proved that if there exists a nonzero skew polynomial $g(X)=b_0+b_1X+cdots+b_mX^m$ in $R[X;alpha]$ such that $g(X)f(X)=c$ is a constant in $R$, then $b_0a_0=c$ and there exist nonzero elements $a$ and $r$ in $R$ such tha...

intercellular adhesion molecule-1 (icam-1) lys469glu (k469e) polymorphism and gly 241arg (g241r) polymorphism might play important roles in cancer development and progression. however, the results of previous studies are inconsistent. the aim of this study was to evaluate the association between icam-1 k469e and g241r polymorphisms and the risk of cancer by meta-analysis.a comprehensive literat...

Because of its unique digital transmission, HD Radio® requires new methods and standards to measure and predict signal coverage, relative to analog FM. Because analog FM reception quality is known to decline gradually with degraded RF signal quality, analog FM service may be quantified in simple terms of signal strength. With digital audio broadcasting, reception quality remains ‘perfect’ until...

to compare the efficacy of acupressure wrist bands, ondansetron, metoclopramide and placebo in the prevention of vomiting and nausea after strabismus surgery. two hundred patients, asa physical status i or ii, aged between 10 and 60 years, undergoing strabismus surgery in farabi hospital in 2007-2008 years, were included in this randomized, prospective, double-blind and placebo-controlled study...

in this paper, we shall define and study the concept of  -statistical convergence and  -statistical cauchy inrandom 2-normed space. we also introduce the concept of  -statistical completeness which would provide amore general frame work to study the completeness in random 2-normed space. furthermore, we also prove some new results.

objective(s):to investigate the effects of local mild hypothermia on the expression of fas, fasl and mmp-3 after cerebral ischemia-reperfusion in rats. materials and methods:male wistar rats were divided into sham-operated group (sham), normothermia group (nt), and hypothermia group (ht). mcao/r model was established by longa’s method, and reperfusion was allowed after 2 hr occlusion. mild hypo...

endometriosis is an estrogen dependent disease. levels of cancer antigen-125 are significantly higher in women with moderate to severe endometriosis. however, patients with unruptured endometriosis rarely have serum ca-125 levels more than 1000 u/ml. this case report presents a diffuse, unruptured ovarian endometrioma in a 29- year-old woman, leading to an extraordinary high serum ca-125 and ca...

asymmetrically mixed matrix matrimid-mil-53 membranes with silicone cover layer were fabricated. for better understanding of membrane fabrication process, three main parameters of fabrication, matrimid concentration, silicone concentration and weight percentage of metal organic framework (mil-53) particles, were optimized by an experimental design method. cross-section sem images were used to s...
