Twenty-two patients underwent cardiac catheterization before and an average of five months after aorto-coronary bypass operation (ACBO). Two groups were examined: 10 patients with all grafts patent, and 12 patients with one or more grafts occluded. All patients improved symptomatically, regardless of graft patency. However, in the occluded group, left ventricular enddiastolic pressure (LVEDP) i...

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...

critical, because true progressors require a change in treatment, but pseudoprogressors should continue with adjuvant temozolomide. Currently, there are no definitive radiologic criteria to differentiate between true progression and pseudoprogression. The response criteria for brain tumours developed by the Response Assessment in Neuro-Oncology Working Group state that apparent radiologic progr...

nonlinear static procedure (nsp) is a common technique to predict seismic demands on various building structures by subjecting a monotonically increasing horizontal loading (pushover) to the structure. therefore, the pushover analysis is an important part of each nsp. accordingly, the current paper aims at investigating the efficiencyof various algorithms of lateral load patterns applied to the...

a new mathematical model for the optimal production isformulated for the inventory management system under time-varyingand stochastic inflation environment for deteriorating items. the timehorizon is finite and demand rate is dependent to the inflation. in thereal situation, some but not all customers will wait for backlogged itemsduring a shortage period, such as for fashionable commodities or...
