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...
Deep drawing of two-layer sheet is a suitable way to achieve product with a desired shape and desired properties in sheet metal forming technology. Control of deep drawing parameter such as thinning is the most important challenge in this process. The most difficult part of this challenge is differences in material properties and geometry of each layer. In this paper, numerical approach has bee...
