in this paper we tried to analyze the relationship between migration, informal settlement, and unemployment in ahvaz as the regional metropolis of khuzestan state. unemployment and migration interaction effect with each other. because on the one hand unequal distribution facilities and services leads to unemployment and job for people, the other hand, mass unemployment in section of the workfor...

Cell migration occurs as a highly-regulated cycle of cell polarization, membrane extension at the leading edge, adhesion, contraction of the cell body, and release from the extracellular matrix at the trailing edge. In this study, we investigated the involvement of SNARE-mediated membrane trafficking in cell migration. Using a dominant-negative form of the enzyme N-ethylmaleimide-sensitive fact...

BACKGROUND Cell migration (restitution) occurs in the early phase of gastric ulcer healing. Tumor necrosis factor (TNF)-alpha is overexpressed at the ulcer margin and plays a physiologic role in gastric ulcer healing. Dexamethasone, which is a potent corticosteroid, delays rat gastric ulcer healing. We evaluated whether dexamethasone inhibited TNF-alpha-stimulated gastric epithelial cell migrat...

Alternative theoretical perspectives have been presented to explain internationally effective factors affecting immigration. For example, the orthodox explanation of migration is based on the concept of wage differentials as an important factor of international immigration. The world system approach declines to interpret theoretically international migration as a phenomenon between independent ...

In order to achieve the virtual machines live migration, the two "pre-copy" and "post-copy" strategies are presented. Each of these strategies, depending on the operating conditions of the machine, may perform better than the other. In this article, a new algorithm is presented that automatically decides how the virtual machine live migration takes place. In this approach, the virtual machine m...

Background: Re-epithelialization has an important role in skin wound healing. Delays in re-epithelialization are more likely to create the chronic wound. Impaired wound healing leads to a large burden of morbidity and mortality. Current treatments based on the use of autografts, allografts and xenografts, suffer from limitations such as, quantity of donor skin available, donor-site infection, p...
