BACKGROUND The present work was designed to detect heavy metal contents of Al, Zn, Fe, Mn, Ni, V, Co, Cr and Cu in sediments and shells of the Trachycardium lacunosum collected in polluted and unpolluted areas along the Persian Gulf. METHODS The samples were taken from surface sediments (0-10 cm) and shells of Trachycardium lacunosum in two separated areas (polluted and unpolluted) in norther...
Seventy-six farmers' varieties of sorghum from Benin were distinguished by amplified fragment length polymorphism (AFLP) and clustered into 45 distinct genotypes. The genotype clusters were evaluated for their Fe, Zn, and phytate concentrations to assess the impact of genetic and environmental effects on the composition of the grains and to identify farmers' varieties with high potential Fe and...
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...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
Nitrogen is usually the most limiting nutrient for crop production. Manganese deficiency in some calcareous soils of Iran has been reported. The objective of this study was to evaluate the effect of N and Mn on the growth and chemical composition of spinach (Spinacia oleracea L.) under greenhouse conditions. The experiment was conducted in a soil from Chitgar series (Fine-loamy, carbonatic, the...

برای بررسی تأثیر phو نسبت نیترات به آمونیوم محلول غذایی بر جذب و غلظت fe، mn، zn و cu ریشه ها و بخش هوایی اسفناج، آزمایشی به صورت فاکتوریل و در قالب طرح پایه کاملاً تصادفی با دو فاکتور شامل ph محلول غذایی در سه سطح 5/4، 5/6، 8 و نسبت نیترات به آمونیوم محلول غذایی در پنج سطح 100:0، 75:25، 50:50، 25:75، 0:100 و با 4 تکرار در بستر پرلیت انجام شد. نتایج نشان داد که تأثیر ph محلول غذایی بر غلظت fe و ...
first of all, in order to determine the high yielding rapeseed varieties, two field experiments were performed in 2006-2008 cropping seasons in agricultural and natural resources research center of markazi province, arak (34º 5´ n; 49º 42´ e, and 1775 m above sea level), iran. in this research, 15 winter rapeseed varieties were compared in a randomized complete block design with three replicati...
eight selected heavy metals (cu, zn, pb, cd, cr, mn, fe and al) in surface and sub-surfacesediments in the northern coast of sfax (tunisia) were studied in order to assess the sediment quality and tohighlight the anthropogenic contributions to heavy metal distributions in the two study sediment levels.multiple chemometric approaches based on geographic information system (gis), enrichment facto...
To provide the basic information about the release of heavy metals from the pyrite tailings of Huangjiagou pyrite mine, the pyrite tailings were investigated through a series of batch experiments under different initial pH of extractant, temperature, liquid-solid (LS) ratio, and soaking time conditions. Moreover, calcium carbonate was added in the pyrite tailings to determine the reduction effe...
