the aim of present study was to determine the impact of two different icu management model, open and semi closed, on resources utilization in intensive care unit.retrospective cohort analysis using data from hospital database was applied to compare the effect of icu management model on icu length of stay and bed disposition of 1064 patients admitted to the general icu of imam khomeini hospital ...

In this paper, we introduce the notions of fuzzy γ-I-open sets and fuzzy γ-I-continuous functions to obtain a decomposition of fuzzy semi-I-continuity. We also investigated the fundamental properties of such functions.

We introduce the concept of fuzzy r-minimal α-open set on a fuzzy minimal space and some basic properties. We also introduce the concepts of fuzzy r-M α-continuous and fuzzy r-M(M∗) α-open mappings, and investigate characterization for such mappings.

In this thesis, we consider semi-algebraic sets over a real closed field $R$ defined by quadratic polynomials. Semi-algebraic sets of $R^k$ are defined as the smallest family of sets in $R^k$ that contains the algebraic sets as well as the sets defined by polynomial inequalities, and which is also closed under the boolean operations (complementation, finite unions and finite intersections). We ...

In this paper, we introduce and study the notion of regular generalized –γ– closed sets. Also, some of their properties are investigated. Further, the notion of regular generalized –γ– open sets and the notion of regular generalized –γ– neighbourhood are discussed. Moreover, some of its basic properties are introduced. Finally, we give an applications of rgγ–closed sets, say γ–regular 1 2 T spa...

A new class of fuzzy closed sets, namely fuzzy weakly closed set in a fuzzy topological space is introduced and it is established that this class of fuzzy closed sets lies between fuzzy closed sets and fuzzy generalized closed sets. Alongwith the study of fundamental results of such closed sets, we define and characterize fuzzy weakly compact space and fuzzy weakly closed space.

In this paper a new generalization of semi-open maps via the concept of sg-closed sets is considered. They are called approximately semi-open maps and are used to obtain a characterization of semi-T1/2 spaces.
