In this paper, new definitions of $L$-fuzzy closure operator, $L$-fuzzy interior operator, $L$-fuzzy remote neighborhood system, $L$-fuzzy neighborhood system and $L$-fuzzy quasi-coincident neighborhood system are proposed. It is proved that the category of $L$-fuzzy closure spaces, the category of $L$-fuzzy interior spaces, the category of $L$-fuzzy remote neighborhood spaces, the category of ...
In this paper, for any non-empty subset C of a pseudo BCI-algebra X, the concept of p-closure of C, denoted by C(pc), is introduced and some related properties are investigated. Applying this concept, a characterization of the minimal elements of X is given. It is proved that C(pc) is the least closed pseudo BCI-ideal of X containing C and K(X) for any ideal C of X...
background: few clinical trials have studied the functional and cosmetic outcomes of different closure tech- niques of surgical incisions. skin wound and incision closure methods may influence the healing process and cos- metic outcome. the present study aims at comparing three different suture techniques of skin closure. methods: in a clinical trial, sixty patients with anterior cruciate liga...
Background and Objective: Nonsteroidal anti-inflammatory agents are the treatment of choice for ductal closure in premature newborn. This study evaluates early and late outcome, as well as the effectiveness of oral ibuprofen in the treatment of patent ductus arteriosus (PDA) in premature infants. Methods: In this clinical trial, all preterm infants below 37 weeks, with documentation of PDA w...
Objective - The aims of this study were to determine the approximate radiographic closure time of the growth plates of the fore and hind limbs of Marghoz goat as a small breed of goat is distributed over the western and North-West of Iran near to the Turkey and Iraqi borders and to compare these closure times with those previously published.Design- Experimental studyAnimals- 20 heal...
in this paper, by presenting some notions and theorems, we obtaindifferent types of fuzzy topologies. in fact, we obtain somelowen-type and chang-type fuzzy topologies on general fuzzyautomata. to this end, first we define a kuratowski fuzzy interioroperator which induces a lowen-type fuzzy topology on the set ofstates of a max- min general fuzzy automaton. also by provingsome theorems, ...
An L-fuzzifying matroid is a pair (E, I), where I is a map from2E to L satisfying three axioms. In this paper, the notion of closure operatorsin matroid theory is generalized to an L-fuzzy setting and called L-fuzzifyingclosure operators. It is proved that there exists a one-to-one correspondencebetween L-fuzzifying matroids and their L-fuzzifying closure operators.
Background : Pilonidal disease incidence is increasing ) 26 people per 100,000 (aged 18 - 40 years old. As a matter of fact, this age range is the most optimal time of anindividual social and economic activities. Thus it was decided to assess the prognosis in patients with pilonidal sinus surgery in Shohada hospital of Khorramabad during 2005-2012. ...
Introduction: antimicrobial activity of irrigants and interappointment intracanal dressing is an important consideration in endodontics . The aim of this study was to evaluate the clinical efficacy of chemomechanical preparation of the necrotic canals with different irrigants and intra canal dressing in the control of root canal infection and sinus tract closure. Materials &Methods: In this ...
In the randomized clinical trial 200 pregnant women reffred to Niknafs maternity center from November 1997 to May 1998 were divided into two groups and underwent cesarean section.in the first group (control) the parietal and visceral peritoneum were approximated with delayed absorbable material whereas in the second group (case) the parietal and visceral peritoneum were left open.the mean age o...
