one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...

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...

In order to study of variation and correlation between yields and yield components in oilseed rape, an experiment was designed using line×tester method. Fifteen hybrid derived from crosses of three spring type and high yielding testers (SPN34, RGS003, SPN1) with five spring lines with moderate yield (SPN3, SPN9, SPN36, SPN30, DH4) were tested using a randomized complete blocks design with two r...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Plant growth regulators (PGRs) are used to prevent reduction in rapeseed grain yield under limited moisture conditions. A field experiment was conducted to investigate the effect of paclobutrazol (0, 50, 100, 150 and 200 mg L-1) on canopy surface temperature and some quantitative and qualitative characteristics of two rapeseed cultivars (Okapi and Natalie) under full irrigation and late season ...

In order to effect of mycorrhiza fungi on the quantitative and qualitative traits of cowpea in different irrigation intervals, this research was carried out in 2017 in Khorramshahr as split plot based on randomized complete block design with four replications. The treatments consisted of different irrigation intervals at four levels of 55, 80, 105 and 130 mm evaporation from class A evaporation...
