Crystal engineering has recently emerged as a method of choice for the design and construction of organic as well as metal-organic functional materials. Crystal engineering attempts to establish packing trends in whole families of compounds and seeks to establish connections between structure and function. The utility of crystal engineering has also been expanded to the nanoscience and the deve...

It is common in many countries that engineers having an academic degree in Civil Engineering are appointed responsible for different tasks related to Bridge Engineering. However, there are serious questions about whether formal university courses in civil engineering could cover the needs of a bridge engineer to fulfill his or her job successfully. Regarding the recent significant advances in t...

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...
