Preparation of magnetitelmaghemite nanometric particles is reported from the precipitation of ferrous dodecyl sulfate micellar solution with methylamine. The size of nanocrystals is controlled by the micellar concentration and by temperature. It varies from 3.3nm to llnm. Magnetic properties are studied for various sizes of maghemite particles.
Anoxic iron-rich sediment samples that had been stored in the light showed development of brown, rusty patches. Subcultures in defined mineral media with ferrous iron (10 mmol/liter, mostly precipitated as FeCO3) yielded enrichments of anoxygenic phototrophic bacteria which used ferrous iron as the sole electron donor for photosynthesis. Two different types of purple bacteria, represented by st...
Abstract The effects of different ferrous sulfate (FeSO 4 ) concentrations on the fatty acid profile blue-green alga Arthrospira platensis cultured in Zarrouk’s medium to produce biodiesel were studied. Different (0, 0.005, 0.01, 0.05, and 0.1 g/L) 0.01 g/L examined biochemical composition acids A. . Findings revealed that highest lowest yields 0 FeSO , respectively. It was also noticed an incr...
To determine the nutritional requirment for iron in fish growth, the effect of daily addition of supplemental ferrous sulfate on the growth of Xiphophorus helleri and Xiphophorus maculatus (the swordtail and the platyfish) was measured by determination of weight gain and hematocrit levels. Both variables increased as a result of the added iron. The effectiveness of the treatment diminished as s...
BACKGROUND Iron deficiency is one of the most common nutritional deficiencies worldwide. It is more prevalent when iron requirements are increased during pregnancy and during growth spurts of infancy and adolescence. The last stage in the process of iron depletion is characterized by a decrease in hemoglobin concentration, resulting in iron deficiency anemia. Iron deficiency, even before it is ...
Background and purpose: Iron deficiency and its related anemia is a common Iranian pregnant women problem. This study evaluated the efficacy of daily and weekly ferrous sulfate supplementation in pregnant women. Materials and Methods: 150 pregnant women enrolled into this randomized controlled field trial. They were received 50 mg elemental iron daily in control group and 100 mg elemental ...
