in this paper, a production inventory model is developed for the business enterprise which consists of three wings. the first wing is for manufacturing new items, the second wing is for collecting the returned items, while third wing is for remanufacturing the returned item. in this model we consider the fact that the storage item is deteriorated during storage periods and salvage value is inco...

cervical cancer is the third most common cancer among women in malaysia. the objective of this study was to estimate the effect of explanatory variables on survival time of cervical cancer patients receiving treatment at a hospital in malaysia.in this retrospective record review study, cervical cancer data obtained from hospital universitisains malaysia (husm) was analysed. the data comprises o...

there are many reports for involvement of atp-sensitive potassium channels in pancreatic, cardiac and vascular smooth muscle cells. this study examined the effect of single doses of k+ channel openers diazoxide, minoxidil and k+ channel blockers chlorpropamide, glibenclamide on serum concentration of aldosterone in male rats. blood samples were obtained 60 minutes after drug treatment and serum...

introduction: dill (anethum graveolens), a herb from from umbelliferae, is used traditionally to treat convulsion and increasing milk production. its antimicrobial, antihyperlipidaemic, anti-hypercholesteroaemic effects and gastric acid secretion reducing effect have been reported. the spasmolytic effect of dill fruit on rat uterus has also been shown recently. the aim of present study was to i...

background: in survival studies when the event times are dependent, performing of the analysis by using of methods based on independent assumption, leads to biased. in this paper, using copula function and considering the dependence structure between the event times, a parametric joint distribution has made fitting to the events, and the effective factors on each of these events would be determ...

this study investigated how english as foreign language (efl) learners with different learning styles (field dependent and field independent) boost up their reading comprehension abilities as they develop their metacognitive skills. to conduct this research, 60 participants were randomly invited to sit pet (preliminary english test) to ensure homogeneity of the participants in terms of language...

in this paper, the conjugate gradient method coupled with adjoint problem is used in order to solve the inverse heat conduction problem and estimation of the time- dependent heat flux using the temperature distribution at a point in a three layer system with none homogeneous boundary conditions. also, the effect of noisy data on final solution is studied. for solving this problem the general co...

in this manuscript, we study the inverse problem for non self-adjoint sturm--liouville operator $-d^2+q$ with eigenparameter dependent boundary and discontinuity conditions inside a finite closed interval. by defining  a new hilbert space and  using its spectral data of a kind, it is shown that the potential function can be uniquely determined by part of a set of values of eigenfunctions at som...

objective(s): the rotavirus nonstructural protein 4 (nsp4) is responsible for the increase in cytoplasmic calcium concentration through a phospholipase c-dependent and phospholipase c-independent pathways in infected cells. it is shown that increasing of intracellular calcium concentration in rotavirus infected cells is associated with the activation of some members of protein kinases family su...
