Measuring the diversity of plant functional types, identifying their characteristics, and their classification will help to identification of woodland germination capacity and implementing appropriate range management programs. The study was designed to measure the species diversity and to identify plant functional types in three adjacent ecological sites in Shimbar or Shirin Bahar region. Duri...

The conventional method to evaluate earthquake induced permanent deformations of slopes is the one proposed by Newmark. In this paper, permanent displacement of slopes is studied using a combination of distinct element and finite difference methods and the results of these numerical evaluations are compared with those of the Newmark's approach. Several parameters involved, including peak ground...

The uniformity parameters in drip irrigation system are influenced by the slope of manifold and therefore, the evaluation of drip irrigation systems is important in slopping lands. In this research, different slopes of 0.2, 6, 11, 16, 20 and 25% were applied on the ground surface and manifold of drip irrigation system with diameters of 50, 63 and 75 mm and length of 70 m were installed on these...

This paper explored how sensation seeking contributes to the likelihood of tanning bed use intentions both directly and indirectly through the way it shapes interaction with peers who use tanning beds and attitudes toward tanning bed. Eight hundred and ninety six (n = 896) male and female college students were recruited for the study. Measured variables included sensation seeking, association w...

Block-flexure is the most common mode of toppling failure in natural and excavated rock slopes. In such failure, some rock blocks break due to tensile stresses and some overturn under their own weights and then all of them topple together. In this paper, first, a brief review of previous studies on toppling failures is presented. Then, the physical and mechanical properties of experimental mode...

Group-threat theorists suggest that increases in the collective threat posed to dominant ethnic and racial groups increase average levels of prejudice and intensify the relationships between individual characteristics and prejudice. However, group-threat theorists focus attention more on differences in the average levels of prejudice across geographic regions and/or time than on differences in ...

To evaluate whether obese patients with a binge eating disorder (BED) have an altered metabolic and inflammatory profile related to their eating behaviors compared with non-BED obese.A total of 115 White obese patients consecutively recruited underwent biochemical, anthropometrical evaluation, and a 75-g oral glucose tolerance test. Patients answered the Binge Eating Scale and were interviewed ...

تقاضا برای اُلفین های (آلکِن های) سبک مانند پروپن، بوتن و ایزوبوتن و محصولاتی که از این اُلفین ها تولید می شود، بالا و رو به فزونی است. چون منابع فسیلی (طبیعی) فاقد الفین های سبک می باشند و بیشتر آنها شامل هیدروکربن های اشباع شده و آروماتیکها می باشد، روش های سنتزی برای تولید اُلفین های سبک اجتناب ناپذیر است. یکی از راههای تولید اُلفینهای سبک، هیدروژن زدایی آلکان متناظر- حذف یک مولکول - با آنها می ب...
