Nitrogen is an indispensable element for plants, being the fourth element as a percentage of plants by carbon, oxygen and hydrogen, in his absence they do not develop as a result of inhibition of chlorophyll synthesis and loss of nutritional values of fruits, hence the efficiency of this element in plans fertility of all plants. Conversely nitrogen (N), plants sensitizes the fall and decreases ...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
Organic fertilizers affect soil chemical and physical properties, particularly chemical forms of zinc in soil solid phase and thereby improve soil Zn availability. The present field study was aimed to evaluate the effects of organic and chemical fertilizer (zinc sulfate) on different zinc fractions in soil solid phase of rhizosphere in two successive years in Rudasht Research Field, Isfahan. Tr...
The combination of microbial reduction and further microbial oxidation of iron was applied to the treatment of food-processing wastewater and recovery of ammonium. Fe2+ ions were formed by ironreducing bacteria under anaerobic conditions. Ammonium was recovered by co-precipitation with negatively charged iron hydroxides produced during oxidation of Fe2+ by iron-oxidizing bacteria under microaer...
To evaluate the effects of iron application on growth characters of Calendula officinalis L. under end season water deficit condition, an experiment was conducted as split plot at the Research Farm of Faculty of Agriculture, Urmia University (latitude 37.53°N, 45.08°E and 1320m above sea level), Urmia, Iran in 2010. Treatments were irrigation (irrigation disruption at first, second, third harve...
Yttrium doping-stabilized γ-Fe2O3 nanoparticles were studied for its potential to serve as a plant fertilizer and, through enzymatic activity, support drought stress management. Levels of both hydrogen peroxide and lipid peroxidation, after drought, were reduced when γ-Fe2O3 nanoparticles were delivered by irrigation in a nutrient solution to Brassica napus plants grown in soil. Hydrogen peroxi...
the aim of this study was to investigate the effect of different amounts of hydrogen peroxide and iron resources in refining petroleum (kerosene) contaminated soils using fenton reaction. for this, ten complex soil samples around tehran oil refinery were collected and after preparations were contaminated with two levels of 10 and 20% of petroleum (kerosene) in triplicate. after reaching equilib...
the study was designed to evaluate the impact of rhizobium bacteria and mycorrhizal fungi and iron sulfate was performed on chickpea plants. treatments rhizobium bacteria (inoculated and non-inoculated), mycorrhizal fungi (glomus mosseae, glomus intraradices and non-inoculated) and various amounts of iron sulfate fertilizer (0, 40 and 80 kg per hectare) with a factorial experiment in a randomiz...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
