Most of river engineering problems are complicated and need to be analyzed by three dimensional models of flow and sediment transport. Considering the fact that computers and numerical methods with great ability of flow and sediment transport simulation are developing quickly, using numerical modeling by engineers is inevitable. Nevertheless, before application, numerical models need to be veri...

bone tissue engineering has been one of the most promising areas of research, providing a potential clinical application to cure bone defects. recently, various stem cells, including embryonic stem cells (escs), bone marrow-derived mesenchymal stem cells (bm-mscs), umbilical cord blood-derived mesenchymal stem cells (ucb-mscs), adipose tissue-derived stem cells (adscs), muscle-derived stem cell...

operation kheibarin which the war engineering supporting of jihad played an important role is one of the major military operations in the eight-year war implemented in hawr al-azimarea in the winter of 1981 with the aim of achieving the basra-to-al-amara road. building a13-km floating bridge named kheibar as thewaterrearsof the units on the forward edge of battle area, construction a 14-km road...

severe hepatic failure accounts for many deaths and raises medical costs each year worldwide. currently, liver transplantation is the most common therapeutic option for patients with end-stage chronic liver disease. due to decrease in the number of organ donors, many in need of transplantation continue to remain on the waiting list. hepatic tissue engineering is a step toward alleviating the ne...

Abstract KI-Engineering – translated as AI Systems Engineering aims at the development of a new engineering practice in intersection and Artificial Intelligence. Its goal is to professionalize use methods systems context. The article defines compares it with historical examples research disciplines that founded disciplines. It furthermore discusses long-term challenges where further needed whic...
