the purpose of the present randomized clinical trial study was to compare the effectiveness of bovine porous bone mineral (bpbm) with and without plasma rich in growth factors (prgf) in the treatment of mandibular class ii furcation defects.in seven patients, nine pairs of symmetric buccal or lingual mandibular class ii furcation defects were treated. in each patient, one defect received bpbm (...

In the highly fragmented truckload transportation industry a substantial fraction of truck movements involves empty trucks, i.e., involves moves that reposition trucks. However, reducing the amount of truck repositioning is difficult because the need for a carrier to reposition its trucks depends on the interactions between the shippers the carrier is serving. Through collaboration, shippers ma...

This paper studies a single vehicle pickup and delivery problem with loading constraints. In this problem, the vehicle contains a number of (horizontal) stacks of finite capacity for loading items from the rear of the vehicle. Each stack must satisfy a last-infirst-out constraint where any new item must be loaded on top of a stack and any unloaded item must be on top of its stack. A large neigh...

© TOUCH MEDICAL MEDIA 2014 43 Abstract Oncoplastic surgery is redefining breast cancer surgery today. Despite the lack of randomised clinical trials, current evidence suggests at least equivalent oncological outcomes, reduced re-excision rates and superior aesthetic results. This review outlines the arguments for the superiority of this new approach over the current standard of care and discuss...

We propose a new unidirectional proxy re-encryption scheme based on lattices. Our construction is collusion-safe and does not require any trusted authority for the re-encryption key generation. We extend a recent trapdoor definition for a lattice of Micciancio and Peikert. Our proxy re-encryption scheme is provably CCA-1 secure in the selective model under the standard assumption.

In this paper, we have proposed an improved genetic algorithm (GA) to solve constrained knapsack problem in fuzzy environment. Some of the objects among all the objects are associated with a discount. If at least a predetermined quantity of the object(s) (those are associated with a discount) is selected, then an amount (in $) is considered as discount. The aim of the model is to maximize the t...
