In this research, the amount of Iron removal by bioleaching of a kaolin sample with high iron impurity with Aspergillus niger was optimized. In order to study the effect of initial pH, sucrose and spore concentration on iron, oxalic acid and citric acid concentration, more than twenty experiments were performed. The resulted data were utilized to train, validate and test the two layer artificia...

Recently, the use of superparamagnetic iron oxide nanoparticles (SPIONS) as a new and promising source of iron in agriculture has been suggested that further investigation is needed before extensive field use. In a greenhouse experiment, the effect of coated magnetite nanoparticles with humic acid (Fe3O4/HA NPs) was investigated on iron deficiency chlorosis and photosynthesis efficiency compare...

background and aim: the aim of this study was to determine the effect of legume intake in therapeutic lifestyle change (tlc) on fasting insulin, fasting blood glucose, hba1c and homeostasis model assessment insulin resistance (homa-ir) in patients with type 2 diabetes. materials and methods: in this randomized crossover trial, 31 subjects with type 2 diabetes in the age range of 50 to 80 years ...

The objective of this study is to develop a simple, environmentally benign alternate analytical method for simultaneous estimation of iron oxidation states. This proposed method of iron speciation is based on 1,10-phenanthroline (phen) modified redox potential of transition metal ions. In a pre-step excess cerium(IV) oxidizes iron(II) in sample to iron(III). Initial back titration of un-reacted...

Food security is a prerequisite for health. Availability and accessibility of food in rural areas is mainly achieved through subsistence production in which community members use local practices to produce and preserve food. Subsistence food production ensures self-sufficiency and reduction of poverty and hunger. The main emphasis with the present study is examining subsistence farming and coll...
