Several notions on soft topology are studied and their basic properties investigated by using the concept of pre open sets closure operator which derived from basics set theory established Molodtsov [1]. In this paper we introduce some separation axioms called Soft R0 R1 in topological spaces defined over an initial universe with a fixed parameters. Many characterizations these have been demons...

purpose: to evaluate the diagnostic signs, intraoperative complications and postoperative outcomes in children with congenital cataract and pre-existing posterior capsule defect (ppcd). methods: this interventional case series was conducted on 14 eyes of 7 patients who underwent lensectomy-anterior vitrectomy for congenital cataract with ppcd. all children had bilateral cataract. preoperative d...

determination of pre-hospital delay time of patients with acute myocardial infarction and seeking ways of speeding up the time for reperfusion is an important factor to lower mortality in these patients. this is a cross-sectional study to determine pre-hospital delay time, its components, and related causes and conditions, obtained in 375 patients with prolonged chest pain referred to four hosp...

Humanitarian organizations pre-position relief items in pre-disaster and distribute them to the affected areas in post-disaster. Improper planning of emergency operations causes more deaths in post-disaster. In this paper, the problem of relief item pre-positioning and multi-period distribution planning is addressed considering lateral transhipment among distribution centres to improve the effi...

abstract background: obesity is an independent risk factor of preeclampsia with unknown mechanism and hyperlipidemia might be a probable case of it. objective: the objective of this study was to determine the role of hyper-triglyceridemi in association with high prepregnancy body mass index and the risk of preeclampsia. materials and methods: the authors conducted this case-control study of 42 ...

The paper explores an environment in which agents are motivated to make unproductive investments with the sole aim of improving their matching opportunities. In contrast to existing work, I add frictions by allowing the investment to be imperfectly observed. The analysis allows for a deeper understanding of the trade-off inherent in related models: investments waste resources but facilitates mo...

Daptomycin is a broad-spectrum, bactericidal agent active against Gram-positive bacteria, acting largely and unusually through membrane depolarization. Activity is markedly affected in vitro by the availability of calcium ions, and its high molecular weight with associated poor diffusion means that conventional disc diffusion testing is not reliable (and as a consequence not available). In orde...
