objective: the genus of ferula belongs to the tribe peucedaneae, subfamily of apioideae and family of umbelliferae with 133 species distributed throughout the mediterranean area and central asia, especially in the former ussr and neighboring countries such as iran. the popular persian name of the most of these species is “koma”. in this research we tried to isolate and elucidate the structure o...
In this article, a new structure is presented for MOS (Metal Oxide Semiconductor)-like junctionless carbon nanotube field effect transistor (MOS-like J-CNTFET), in which dual material gate with different work-functions are used. In the aforementioned structure, the size of the gates near the source and the drain are 14 and 6 nm, respectively, and the work-functions are equal and 0.5 eV less tha...
A fundamental problem is the use of DEA in multistep or multilevel processes such as supply chain, lack of attention to processes’ internal communications in a way that the recent studies on DEA in the context of serial processes have focused on closed systems that the outputs of one level become the inputs of the next level and none of the inputs enter the mediator process. The present study a...
Introduction: Organization structure and manpower constitute two origin basic for an organization and for engendering an organization both must be exist. The purpose of this survey was to investigate the type of the organization structure (mechanic and organic) from viewpoint of Seniors and Juniors managers in Shiraz educational hospitals and organizational creation in apiece two structure. Met...
New wintering populations of Whooper Swan have been recently reported from west Asia, a lack of information about the population and its origin. The understanding the genetic structure and connectivity are crucial for determining strategies of management for its conservation programs. The samples were collected from two populations in northern Iran, Finland, Sweden, and Iceland, where with larg...
