We propose a model of dynamic traffic assignment where strategic choices are an integral part of user behaviour. The model provides a discrete-time description of flow variation through a road network involving arcs with rigid capacities. A driver’s strategy assigns, to each node of the network, a set of arcs in the forward star of that node, sorted according to a preference order. The main ele...

background a fall in plasma concentration of energy status related hormones (leptin, insulin-like growth factor-1 (igf-1) and insulin) and body energy expenditure occurs in response to short term fasting. nevertheless, the relations of the fasting-induced changes in energy related hormones and metabolites with fasting energy expenditure (fee) under extended fasting condition have received littl...

wound healing has always been among important and crucial subjects in medicine. morphine dependency has also been a social and health problem in the middle east. this study was aimed to investigate the effects of morphine dependency on pro-inflammatory and fibroblast cell recruitment, as well as re-epithelialization and the revascularization processes involved in secondary intention wound heali...

Introduction: Root remediation when the initial treatment fails is the most basic treatment before any other surgical procedure. The aim of this study was to evaluate the factors affecting the success and failure of endodontic treatment in a period of 6-24 months.Materials and Methods:This cross-sectional analytical study was performed during 1996-94 with the participation of 76 patients, 19 (2...
