normal 0 false false false en-us x-none ar-sa since its first discovery in an iranian male in 1961, zinc(zn) deficiency in humans is now known to be an important malnutrition problem world-wide. it is more prevalent in areas of high cereal and low animal food consumption. the diet may not necessarily be low in zinc, but its bio-availability plays a major role in its absorption. phytic acid is t...

the lead and zinc sample from goosh-e-fill mine with 2.4%pb, 8.0%zn and 10.0% fe, was used in different flotation experiments to recover lead and zinc minerals. the valuable minerals in prepared sample were oxidized and the results showed that the lead minerals floated at ph= 9.5 and 11.5, probably it can be due to existence of two or more types of lead minerals. the best result was achieved fo...

Background: Thalassemia constitutes a major public health problem causing a significant burden on children and their families. Zinc deficiency plays an important role in many thalassemia-related complications like growth retardation, hypogonadism and delayed puberty which are frequently noted in adolescent age. Although zinc is supplemented to thalassemic patients visiting Day Care Center, Yang...

effect of concentration parameters on recovery of zinc oxidized minerals from lead flotation tailings of dandy mineral processing plant in north-western iran was studied. a sulfidization-flotation method has been used on a laboratory scale to investigate the effect of various reagents such as sodium sulfide as sulfidizing agent, primary amine as collector, dispersants and flocculants with diffe...

epilepsy is a disorder categorized by recurrent seizures and leads to changes in neuronal death and neurogenesis. recently the search for new targets in the therapy of epilepsy has focused on brain inflammation because brain inflammation and the associate blood brain barrier damage appears to be basic part of epilepsy pathophysiology-erythropoietin (epo) regulates biological processes counting ...

This report introduces a method for the solution of the Convection-Diffusion equations (CDE) that combines Genetic Programming with Stochastic Bernstein Interpolation. Significantly, it is being used to solve a problem that has resisted analysis for a long time using other methods. Although the method in this report solves the one-dimensional CDE which has also been solved analytically and opti...

A computation is a temptation that should be resisted as long as possible. "

introduction: ferric sulfate pulpotomy is a safe and effective method of the pulpotomy of primary teeth. but the results of different studies indicate low success rate of ferric sulfate pulpotomy in comparison to formocresol pulpotomy and a portion of these failures may be related to stimulating and harmful effects of zinc oxide eugenol paste. the aim of this study was to determine and compare ...
