background: increasing the complexity in modern radiotherapy techniques have increased the delivery time lowering consequently the treatment efficacy. through simulating the delivery time delay encountered in such techniques, its’ effect on two cancer cell lines and the compensating doses given to prevent such effect was investigated. materials and methods: f10b16 and 4t1 cancer cell lines were...

One of the most vital construction project aspects is to complete a in minimum time restricted time–cost trade-off. Overlapping activities’ planning and their impact on under limited resource constraints should be considered. This study aims develop model for optimizing schedule cost regarding overlap activities impacts. reviews previous studies changes past likely produce additional reworking ...

this paper addresses the vehicle routing problem with delivery time cost. this problem aims to find a set of routes of minimal total costs including the travelling cost and delivery time cost, starting and ending at the depot, in such a way that each customer is visited by one vehicle given the capacity of the vehicle to satisfy a specific demand. in this research, a hybrid metaheuristic approa...

Dear Editor, I read with interest the article by Yazdani, M, et al, on the administration of magnesium sulfate to women with premature labor and its effect on the bleeding time, published in the Iranian Journal of Medical Sciences.1I found it interesting but I would like to make some points regarding to this study:There are several methods for the measurement of bleeding time (BT). Those includ...
