Stem cell research has obtained much prominence in recent years for its therapeutic potential in dealing with serious diseases, many of which are essentially incurable by routine therapies. Mesenchymal stem cells with pluripotency and immunomodulatory properties are suitable candidates for tissue engineering and regenerative medicine. Today, nanofibrous scaffolds are widely used in tissue en...
without any doubt, road safety (rs) needs a precise planning in road accident prevention. rs effects on different fields of the life. therefore, response to this need in order to promote the rs as well as to save more lives is the most asset in each country. in the recent years, statistics have been shown that the numbers of mortalities due to road crashes decreased. this shows the true motion ...
aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (pcl), poly (vinyl alcohol) (pva) and hydroxyapatite nanoparticles (nha). the morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...
articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. the scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. cartilage tissue engineering requires 3 components: cells, scaffold, and environment. owning to their ...
tissue engineering is based on three main factors including scaffolds, cells and growth factors. natural scaffolds derived from decellularized tissues and organs have been successfully used in tissue engineering. decellularization studies have shown that natural scaffolds which maintaine their main structure and properties could be a suitable tool for studying cellular behaviors and preparation...
We have developed thin film heaters/sensors that can be integrated on top of superlattice microcoolers to measure the Seebeck coefficient perpendicular to the layer. In this paper, we discuss the Seebeck coefficients of InGaAs/InAlAs superlattices grown with Molecular Beam Epitaxy (MBE) that have different doping concentrations, varying between 2e18, 4e18, and 8e18 to 3e19 cm. It was interestin...
study of the engineering education from several aspects needs to be paid attention. in order to make ease the learning process, to get successful in educational courses and technical programs, and having a useful performance in working areas. these challenging issues make it necessary to educate engineers with ability of special competencies and skills as social capital, creativity, group worki...
Genetic engineering innovations are protectable in intellectual property law system as intellectual properties. Protection of many of these innovations in economic, environmental, moral and human rights fundamentals is justifiable. Based on existing fundamentals in field of mentioned aspects, protection of genetic engineering innovations is provided to application of economic, environmental, mo...
this article deals with the engineering education of mechatronic in the different universities of canada, while every educational aspect of their curriculum is described in detail. this study shows that the desing of any educational program to some extend depends on the department where the program is carried out and the cooperation and help of the other departments. it seems that gradually thi...
