1. The availability of iron, zinc and calcium in a diet containing 400 g 'fibre-filler' (a mixture of bran, fruit and nuts, used in the F-plan diet)/kg diet (HF diet) was measured by whole-body counting in rats, using 59Fe, 65Zn and 47Ca as extrinsic labels, and compared with a diet of similar mineral content but no 'fibre-filler' (LF diet). Absorption of Fe and Ca was significantly higher from...

the higher levels of essential elements in soil may be caused in optimum yields and crop quality. so it seems to be necessary to examine different levels of nutrients like fe and zn on plants and their productivity. to evaluate effects of iron and zinc application on yield and yield components of pimpinella anisum an experiment was conducted at the research farm of urmia university in 2009. tre...

abstract- to evaluate effects of different soil moisture conditions namely, phosphorus (p) and zinc (zn) application, on extractable zn and fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. the first experiment was performed with the following factors; incubation time at four leve...

methanol steam reforming plays a pivotal role to produce hydrogen for fuel cell systems in a low temperature range. to accomplish higher methanol conversion and lower co production, the reaction was catalyzed by cuznfe mixed oxides. various ratios of fe and cu/zn were coprecipitated in differential method to optimize the cuznfe structure. the sample containing 45cu50zn5fe (wt. %) revealed its m...

Zinc-cyanide complexes are found in gold mining effluents and in metal finishing rinse water. The effect of Zn(II) on the oxidation of cyanide by ferrate(VI) (Fe(VI)O(4)(2-), Fe(VI)) was thus investigated by studying the kinetics of the reaction of Fe(VI) with cyanide present in a potassium salt of a zinc cyanide complex (K(2)Zn(CN)(4)) and in a mixture of Zn(II) and cyanide solutions as a func...

This study was undertaken to monitor Fe, Zn and Cu contents in several maternal tissues and the products of conception of rats submitted to moderate food restriction during pregnancy. Two groups of female rats, nonpregnant (NP) and pregnant (P1), were fed ad libitum. A second group of pregnant rats (restricted diet, P2) was fed for 14 days with the same intake as NP, then the intake was increas...

The Ag, Co, Cr, Fe, Hg, Rb, Sb, Sc, Se, and Zn contents in normal tissue (n=37) and adenocarcinoma (n=37) of the human prostate gland were investigated using non-destructive instrumental neutron activation analysis with high resolution spectrometry of long-lived radionuclides. Mean values (M  SΕΜ) for content (mg/kg, dry mass basis) of trace elements in adenocarcinoma were: Ag – 0.2420.039, C...

High resolution spectra of 34 halo population dwarf and subgiant stars have been obtained with VLT/UVES and used to derive sulphur abundances from the λλ8694.0, 8694.6 and λλ9212.9, 9237.5 S i lines. In addition, iron abundances have been determined from 19 Fe ii lines and zinc abundances from the λλ4722.2, 4810.5 lines. The abundances are based on a classical 1D, LTE model atmosphere analysis,...

The effect of Fe fortification on the absorption of Zn was studied by radioisotopic labelling of single meals, followed by measurements of whole-body retention of 65Zn at 14 d after intake. Healthy adult volunteers participated in the study. Weaning cereal, wheat bread and infant formula, foods that are all frequently Fe-fortified, were evaluated in the study. The amounts of Fe added as FeSO4 w...

this research aims  to monitor the trace elements content (cr, cu, pb, cd, ag, al, mn, mg, zn and fe) in the tissues of the muscle and liver of silver carp (h. molitrix ) and stone moroko (p. parva) from zarivar wetland in western iran. this research was cross-sectional. the research specimen  was fish caught from zarivar wetland. metal concentration analysis was carried out utilizing an  icp. ...
