background: chitosan nanoparticles have become of great interest for nanomedicine, biomedical engineering and development of new therapeutic drug release systems with improved bioavailability, increased specificity and sensitivity, and reduced pharmacological toxicity. the aim of the present study is to synthesis and optimization of chitosan nanoparticles for industrial and biomedical applicati...

in previous years, various studies have been carried out on engineering education and training. based on the results and world transforms, developed strategies have been offered in academic or industrial world, which start from preparation for information technology era to focusing on sustainable developments and global engineering in current age. on the other side, education from research univ...

tissue-engineered biomaterials have existed approximately 40 years as simple biomimetic structures. replacement of human tissue with new tissue can be accomplished by generating replacements outside of the body or in situ in the body. in each case, the key elements are described as the tissue engineering triad of scaffolds, cells, and signals. scaffolds can be produced synthetically or derived ...

quality assessment in an educational activity is the most important action for improving this process and its totally or partly renewed resumption. quality assessment compares the existing and the desired situation. in the education system outcome, review the existing and desired situation is a turning point of quality assessment. therefore it is necessary to describe outcome desired situation ...
