abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...

Background and Objectives: Reducing salt intake is one of the strategies for preventing and controlling noncomunicable diseases. Bread is one of the important sources of salt, and reducing its salt content can play a major role in reducing salt intake in the community. Therefore, this study was conducted to evaluate the effect of reducing the consumption of salt and substituting it with potassi...

To improve crop yields and increase of production performance in marginal areas, the use of genetic potential of crops in terms of morphological and physiological characteristics can lead to yield improvement and increase of production performance in areas with saline water and soil salinity. In order to evaluate genotypic variation in growth and physiological traits of different bread wheat cu...

An understanding of physiological mechanisms of salt tolerance is necessary for breeding programs, in order to select the desired trait in different wheat genotypes. Three bread wheat genotype differing in salt tolerance were employed to assess ion distribution and growth responses under saline conditions. To evaluate ion distribution in plant, sodium and potassium concentrations as well as K+/...
