The main objective of the distribution system planning is to determine the substation location, size and its service area, number of feeders and their routes. The planning problem is solved by classical methods to non traditional soft computing techniques, hence in this work, soft computing technique known as Simulated Annealing is used. Simulated Annealing is a thermal process for obtaining lo...

introduction: human hematopoietic stem cells (hhscs) have been used for transplantation in hematologic failures. because the number of hhscs per cord blood unit is limited, the expansion of these cells is important for clinical application. it has been reported that cytokines and feeder layer provide a perspective to in vitro expansion of hhscs. in this regard, cord blood cd34+ cells expanded a...

Human diploid fibroblast cells produce a spectrum of necessary growth factors and extracellular matrix (ECM) components essential for growth and proliferation of a variety of other cell types. In this study, the effect of five human embryonic fibroblast cell lines, isolated from liver, lung, skin and foreskin tissues, was investigated. A coculture system analyse was employed to cloning efficien...

The linehaul-feeder vehicle routing problem with virtual depots and time windows (LFVRPTW) is a new version of city logistics. Four important issues are explored and fifteen sample examples used for demonstration. First, the LFVRPTW always yields better results than the vehicle routing problem with time windows (VRPTW). Second, LFVRPTW is advantageous compared with VRPTW. Third, more virtual de...

Bachgroun: Hematopoietic stem cell derived from umbilical cord blood (UCB) has been used for regenerative medicine in hematological abnormalities. MicroRNAs are important regulators of gene expression that control both physiological and pathological processes such as development of tissue and cancer. Some studies have shown that miR-33, has a critical role in control of self-renewal cells. He...
