This paper is a report on the synthesis of the Fe3O4@Ag core-shell with high saturation magnetization of magnetite nanoparticles as the core, by using polyol route and silver shell by chemical reduction. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy analyses confirmed that the particles so produced were monophase. The magnetic properties of the product were investigated by...

Water saturation determination is one of the most important tasks in reservoir studies to predict oil and gas in place needed to be calculated with more accuracy. The estimation of this important reservoir parameter is commonly determined by various well logs data and by applying some correlations that may not be so accurate in some real practical cases, especially for carbonate reservoirs. Sin...

AIM To re-evaluate the diagnostic criteria of insulin resistance hepatic iron overload based on clinical, biochemical and histopathological findings. METHODS We studied 81 patients with hepatic iron overload not explained by known genetic and acquired causes. The metabolic syndrome (MS) was defined according to ATPIII criteria. Iron overload was assessed by liver biopsy. Liver histology was e...

BACKGROUND Serum ferritin is normally a marker of iron overload. Ferritin genes are sited at chromosomes 19 and 11. Regulation of ferritin synthesis involves an interaction between an iron regulatory protein (IRP) and part of the ferritin mRNA designated the iron regulatory element (IRE). A disorder of ferritin synthesis resulting in hyperferritinaemia in the absence of iron overload has been d...

325 female students of zahedan at the average age of 16.2 years old (16-22) were randomly selected to study the prevalence of iron deficiency anemia. hb, hematocrit, mcv, mchc, iron, tibc and ferritin were measured. results showed that in the population studied 3.4%, 27.7%, 4.3%, 11.7%, 25.5%, 11.4% had their hb, mcv, serum iron, tranferrin saturation, ferritin respectively below the who standa...

The operational characteristics during transients are significantly influenced by magnetic saturation in electrical equipment. For the computation of steady-state rated operation multiphase induction machines, assumption linear behavior iron core classical machine models may be sufficient. mathematical considered differ terms existence or absence dynamic cross-saturation effects. approach that ...
