determination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولThe greater omentum as a site for pancreatic islet transplantation
The greater omentum is a highly vascularized anatomical structure in the peritoneal cavity. Its main components are connective, adipose and vascular cells, along with specialized immune cells. The omentum functions as a site for fat accumulation, it has adhesive properties to control traumatized and inflamed tissues, and a function in local hemostasis, immune responses, and revascularization. O...
متن کاملBone tissue engineering with periosteal-free graft and pedicle omentum.
BACKGROUND The histological characteristics of periosteum make it a specific tissue with a unique capacity to be engineered. Higher flexibility of the greater omentum is useful for reconstructive surgery as it facilitates not only filling of the site of infections such as myelitis, but also is effective in filling complicated defects of the soft and hard tissues, and these criteria make it suit...
متن کاملPedicled omentum versus free omental graft for myocardial revascularization.
The most frequently used method for myocardial r e v e t i o n today is by direct arterial implantation into the heart in conjunction with use of a free omental graft. The question that is raised is whether the pedicled omentum might not be a greater s o m e of extra-cardiac blood than that supplied by the free omenlal graft. The intact omentnm has been used in the past, but never received clin...
