Migration is the permanent movement of some people called migrant, from one place to another for some reasons and values. Their migration is determined by some values and goals that lead to changes in migrants’ interaction system. In human history the shape of migration was changed due to social and environmental changes. From the eve of 19 century migration became important social phenom...

The migration of packaging material constituents into food is a product of the interaction between the food and packaging material. This phenomenon is of importance because some migrating substances may be toxicologically carcinogenic and endanger the consumer safety. Polystyrenes are used in many food-contact applications for the packaging of aqueous-based, fatty and dry foods. The correlation...

introduction census data of iran show that about 68.5% (1956) to 29% (2011) of rural population has decreased over the past half-century. rural population has rapidly declined over the last half century and is influenced by several factors, one of which is rural- urban migration. although the percentage of rural to urban migration (20%) and urban to rural one (17%) from 1996 to 2006 show less d...

Objective(s): To investigate the role of autophagy in advanced glycation end products (AGEs)-induced proliferation and migration in rat vascular smooth muscle cells (VSMCs).Materials and Methods: After culture, VSMCs were treated with 0, 1, 10, and 100 μg/ml concentrations of AGEs. Autophagy specific protein light chain 3 (LC3)-I/II was determined by western blotting, autophagosomes were observ...

BACKGROUND AND OBJECTIVES There has been a growing interest in the anesthetic use of dexmedetomidine, a new alpha2-adrenergic agonist, due to decreased anesthetics consumption and better cardiovascular stability that it promoter. This study aimed at investigating cardiovascular effects of two different dexmedetomidine doses in anesthetized dogs. METHODS The study involved 36 adult dogs anesth...

Background & objectives: Polyethylene terephthalate (PET) containers have many applications in the food industry. Although there are numerous advantages for PET it also has some disadvantages, one of which is the migration of materials from the container into the material inside. In this study, the effect of two factors of storage time and temperature on the migration rate was evaluated and mod...

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...

Using in situ high-resolution transmission electron microscopy, we have explored migration mechanism of a grain boundary in a GaN bicrystal as a model system. During annealing at 500 °C, the grain-boundary region underwent a decrease in thickness, which occurred by decomposition or sublimation of GaN during annealing at 500 °C coupled with electron-beam sputtering. The decrease in thickness cor...
