Leghemoglobin may be isolated from soybean root nodules as a complex, leghemoglobin a-X of ferric leghemoglobin with a low molecular weight ligand X. That complex dissociates at neutral or alkaline pH and the ligand X may be separated from free leghemoglobin by ultrafiltration. The complex is regenerated by combining ferric leghemoglobin with X. The affinity of ferrous leghemoglobin for X is ve...

in this paper, grafting of acrylic acid monomer on gum tragacanth was performed. variable of experiment included concentration of initiators and monomer, time, and temperature. grafting efficiency was measured in the term of percentage of grafting (%g) and percentage of grafting efficiency (%e). effectiveness of grafted gum in ferrous ion removal at different condition was assessed. according t...

environmental pollution with heavy metals is a global struggle. phytoremediation is an effectiveand low-cost technology for refinement of polluted soils. this research was conducted in zanjan province(located in north west iran) where metallurgical industries are developed quickly. in this study, based on theheavy metals contamination of soil in the studied area six sampling sites were selected...

the purpose of this research was identifying factors affecting the development of processing and complementary industries of date palm in khouzestan province. the method of research was causal comparative. the population of this research was managers in processing and complementary industries of date palm products of khouzestan province (n=100). the return rate was 94% (n=94). by census method...

The application of hyperspectral sensors in the development of machine vision solutions has become increasingly popular as the spectral characteristics of the imaged materials are better modeled in the hyperspectral domain than in the standard trichromatic red, green, blue data. While there is no doubt that the availability of detailed spectral information is opportune as it opens the possibili...

iron oxide is an important biological agent that has a key role in medical processes; however, the mechanism whereby it provides iron for human and animal cells and its biological uses remains unclear. we aimed to evaluate the effects of oral iron oxide on serum iron status and compare the results with those of iron sulfate as a reference salt. fifteen adult rabbits were divided into 3 groups o...
