there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
conclusions the present clinical study suggests that the transmission of an hbv genotype other than genotype d, namely hbv genotype g, is possible in turkey. epidemiological and clinical information on genotype g infection is currently limited, and this is most likely due to its low prevalence throughout the world. therefore, it may be important to determine the epidemiologic and molecular char...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
background: tuberculosis (tb) remains as a major cause of death around the world. construction of a new vaccine against tuberculosis is an effective way to control it. several vaccines against this disease have been developed. the aim of the present study was to cloning of tb10.4 gene in pcdna3.1+ plasmid and evaluation of its expression in eukaryotic cells. methods: firstly, tb10.4 fragment wa...

As more and more organizations move from functional to process-based IT infrastructure, ERP systems are becoming one of today’s most widespread IT solutions. However, not all firms have been successful in their ERP implementations. Using a case study methodology grounded in business process change theory, this research tries to understand the factors that lead to the success or failure of ERP p...
cell therapy is a modern approach in the treatment of most of the diseases which uses stem cells and it has been recently developed rapidly. cell therapy has shown satisfactory results in this way. our country, iran, has played an important role in the development of this new method and the results of stem cell treatment used for the most of the diseases were successful. the results have led to...
