sale is the alienation of goods with all presumptive, objective and, legal rights related to them in a way that a buyer can have the goods in absolute legal possession. any defects in seller’s ownership, such as the right of easement, usufruct or lien belong to the third party interferes with the absolute ownership of the buyer and his rights. a kind of these rights recognized and protected by ...

development of antibiotic resistance in intensive care units (icus) is a worldwide problem. the purpose of this study was to evaluate the effect of an antibiotic stewardship program (asp) by carbapenems restriction on gram-negative antimicrobial resistance in icu. the study was designed in a 21 bedded general icu of a teaching hospital with two wings (one and two) in tehran, iran. carbapenem pr...

background and objective:acinetobacter spp.a gram-negative coccobacillus is increasingly reported as important cause of nosocomial infections. multi-drug resistance (mdr) ofacinetobacterspp., raises concerns over our ability to treat serious infections with these organisms. the aim of this study was to determine the frequency and associated risk factors for infections with mdr acinetobacter spp...

background and purpose: organizational commitment has been on a downward trend among medical staff in different sections of the health care system. this study aimed to investigate the level of organizational commitment among the nurses engaged in the intensive care units (icus) of mazandaran heart center in sari, iran. methods: this descriptive-analytical study was conducted at the educational ...

background: parenteral nutrition (pn) is a valuable life saving intervention, which can improve the nutritional status of hospitalized malnourished patients. pn is associated with complications including hyperglycemia. this study was conducted to compare two methods of blood glucose control in traumatic brain injury patients on pn. materials and methods: a randomized, open-label, controlled tri...

conclusions finally, in order to prevent the occurrence and reduce the consequences of identified errors the following suggestions were proposed : appropriate training courses, applying work guidelines and monitoring their implementation, increasing the number of work shifts, hiring professional workforce, equipping work space with appropriate facilities and equipment. background although healt...

recently, the finished cost reduction policy-as an efficient economic policy for competitiveness of domestic products beside foreign competitors-has been paying attention by ministry of commerce of iran. at the fist look, the protection of intellectual property such as inventions increases the finished cost of products; but intellectual property protection can be effective in finished cost redu...

‎Let $D$ be an integral domain with quotient field $K$‎, ‎$E$ be a $K$-vector space‎, ‎$R = D propto E$ be the trivial extension of $D$ by $E$‎, ‎and $w$ be the so-called $w$-operation‎. ‎In this paper‎, ‎we show that‎ ‎$R$ is a $w$-FF ring if and only if $D$ is a $w$-FF domain; and‎ ‎in this case‎, ‎each $w$-flat $w$-ideal of $R$ is $w$-invertible.

In this paper we give conditions for a tuple of commutative bounded linear operators which holds in the property of the Hypercyclicity Criterion. We characterize topological transitivity and semi-hereiditarily of a dynamical system given  by an n-tuple of operators acting on a separable infinite dimensional Banach space .

Let $T$ be a bounded linear operator on a Hilbert space $mathscr{H}$. We say that $T$ has the hyponormal property if there exists a function $f$, continuous on an appropriate set so that $f(|T|)geq f(|T^ast|)$. We investigate the properties of such operators considering certain classes of functions on which our definition is constructed. For such a function $f$ we introduce the $f$-Aluthge tran...
