abstract:migration is one of the main factors in regional development and social and demography policymakers pay attention to it. this phenomenon has different functions. the amount of satisfaction on dissatisfaction from migration process can be a sign of positive or negative function for migrants. the goal of this research is to survey the relation between social capital and satisfaction from...

Cell movement requires the coordinated reception, integration, and processing of intracellular signals. We have discovered that the protein kinase A anchoring protein AKAP220 interacts with the cytoskeletal scaffolding protein IQGAP1 to influence cell motility. AKAP220/IQGAP1 networks receive and integrate calcium and cAMP second messenger signals and position signaling enzymes near their inten...

the present study investigates the central concerns of the use of visuals within the four efl textbooks taught at iranian high schools which have been prescribed by the ministry of education. to do this, the four efl textbooks were evaluated and analyzed. descriptive statistics were used to analyze data quantitatively. the analysis indicated that over the four textbooks, 95.71 percent of all vi...

nomad’s livelihood is based on continuous migration between summer and winter pastures to obtain forage for their animals and access to contented weather. this living way has long history in iran which formed in accord with climate. in recent century, modernization has been caused many changes in traditional living way of nomads. therefore, nomads have no more their role and function as in th...

objective: transplantation of mesenchymal stem cells (mscs) can promote functional recovery of the brain after hypoxic-ischemic brain damage (hibd). however, the mechanism regulating msc migration to a hypoxic-ischemic lesion is poorly understood. interaction between stromal cell-derived factor-1α (sdf-1α) and its cognate receptor cxc chemokine receptor 4 (cxcr4) is crucial for homing and migra...

Biogeography-Based Optimization (BBO) has recently gained interest of researchers due to its simplicity in implementation, efficiency and existence of very few parameters. The BBO algorithm is a new type of optimization technique based on biogeography concept. This population-based algorithm uses the idea of the migration strategy of animals or other species for solving optimization problems. t...
