this study aimed at identifying required competencies for the labor market by the graduates majoring in the agricultural extension education field. the study population included undergraduates, faculty members, and employers, as related to bachelor level in three extension and education departments at bu ali sina, tehran, and shiraz universities of iran. the study has employed both quantitative...
The occurrence of unplanned accidents is a global issue, and lack of preparedness and resilience in this area can lead to significant losses. Therefore, restitution is an important way to strengthen urban communities by utilizing their capacity. In this regard, the main objective of this research is to investigate the difference in the level of resilience indices in the three districts of a met...
Undoubtedly, Khorram-Abad Country has been considered as one of the most beautiful, scenic and pleasant weather areas of Iran because of many natural, cultural, historical, etc attractions. Despite the great potential for ecotourism development in this country, it has not been implemented a good plan for ecotourism development in this area. This study intends to identify the effective criteria ...
Activation of extracellular signal-regulated kinase (ERK) has been shown to be necessary for NMDA receptor-dependent long-term potentiation (LTP). We studied the role of ERK in three forms of NMDA receptor-independent LTP: LTP induced by very high-frequency stimulation (200 Hz-LTP), LTP induced by the K(+) channel blocker tetraethylammonium (TEA) (TEA-LTP), and mossy fiber (MF) LTP (MF-LTP). We...

We present LEOPARD, a fanout optimization algorithm based on the effort delay model for near-continuous size buffer libraries. Our algorithm minimizes area under required timing and input capacitance constraints by finding the tree topology and assigning different gains to each buffer to minimize the total buffer area. Experimental results show that the new algorithm achieves significant buffer...
