introduction tongue is one of the most important organs in the oral cavity which has significant roles in different functions such as speaking, mastication, swallowing, breathing, etc. the tongue may be influenced by internal diseases sooner than other organs and also may be involved in some abnormalities that some are developmental and some of them are genetical and environmental. this study h...

abstract   soft tissue sarcomas of the oral cavity are uncommon malignancies those of smooth-muscle origin are extremely rare. leiomyosarcomas of the tongue are very rare. either surgery or radiation therapy with or without chemotherapy are the treatment modalities which improve prognosis. we are presenting a 32-year-old man with leiomyosarcoma of the lateral aspect of the oral tongue with neck...

In many industries, reducing the size of compression system represents a significant goal for designers. fact, increasing power density compressor actually means lowering production costs. The chief purpose this study is to compare, in terms aerodynamic performances, centrifugal consisting an impeller and volute, innovative concept based on principle two successive impellers designed work count...

Now a day centrifugal pumps are vital components of industries. Certainly, one of the most important specifications of centrifugal pumps are the performance curves. In the present work, performance curves of a centrifugal pumps are obtained by Computational fluid dynamics (CFD) and as an outcome, CFD results compare by practical curves. At the first step impeller and volute are designed with tw...
