different ossificant materials have been used for induction of bone repair in many studies, and bone matrix gelatin which contains bone morphogenic proteins is one of the best ones. in present study we evaluated the role of this material in acceleration of bone repair in rabbit tibia. a hole of 3.5 mm diameter was made on right tibia of 10 and 12 rabbits as study and control group respectively....

One of the most important benefits of ServiceOriented Computing is to foster the satisfaction of end-user needs through the automatic generation of composite services out of simpler services existing in the user environment. Different approaches have been proposed in the last years to address this issue, e.g., based on model-checking or AI planning. Still, these approaches do not cope with the ...

Background: Nickel is a carcinogenic, heavy metal released through industrial activities and via natural resources. It is able to cause DNA damages by reducing the efficiency of DNA repair mechanisms. However, the exact time point at which it is able to interfere with these mechanisms is not yet clearly understood. Methods: To find the most nickel-vulnerable time of repair mechanisms, human de...

In this paper we consider a system consisting of a supplier with a single processing unit, a repair center, and a retailer with Poisson demand. We assume that the retailer applies one-for-one ordering policy with backorders for his inventory control. The retailer’s orders form a queue in the supplier processing unit. We also assume that a certain fraction of the products produced by the supplie...
