during 2010-2011 a faunistic survey was carried out for collection and identification of edaphic mesostigmatic mites (acari: mesostigmata) in jiroft and suburb. mites were extracted from soil samples by berlese funnel. the mites were cleared in nesbit fluid and were mounted in hoyer medium on microscopic slides. in this study 43 spices from 26 genera and 16 families were collected and identifie...
levels of the heavy metals copper (cu), zinc (zn), lead (pb), cadmium (cd), chromium (cr), nickel (ni), iron (fe) and manganese (mn) were determined by graphite furnace atomic absorption spectrophotometer (model 67og) in coastal water, sediments and soft tissues of the saccostrea cucullata, from the intertidal zone at five stations in the gulf of chabahar on the iranian coasts along the oman se...
The concentrations of essential elements in the milk of Croatian Coldblood mares and LittoralDinaric donkey were measured. The mean element contents in horse milk were (mg/kg): Ca 687.1, Mg 72.1, K 637.7, Na 143.5, Cu 0.126, Fe 0.235, Se 0.01, Zn 2.06, Mn<0.01. In donkey milk, the mean element contents were (mg/kg): Ca 815.4, Mg 80.8, K 887.7, Na 217.6, Cu 0.027, Fe 0.196, Zn 2.36, Mn 0.016. In...
this study was carried out to determination of in vitro binding capacity of organic (wheat and barley) and inorganic (perlite) sources for mn, zn, cu, and fe. for this reason wheat and barley were analyzed chemically for moisture, protein, ash, and ether extract, total carbohydrate, ndf, adf, adl, crude fiber, viscosity, cellulose, and total dietary fiber. the in vitro mineral binding capacity ...
the present study aimed to investigate the possible effects of focused highlighted error feedback on grammatical accuracy of writing among iranian intermediate efl learners. after selecting 52 homogenous participants from among 70 university students attending azad university of rasht and randomly dividing them into two intact groups of 26 students, the researcher exposed the participants of th...
Nitrogen is usually the most limiting nutrient for crop production. Thus, N fertilizer is widely used by farmers. Moreover, Mn deficiency in some calcareous soils of Iran with high pH has been reported. Therefore, the addition of nitrogen and manganese to achieve the optimum yield is necessary. The objective of this study was to evaluate the effect of N and Mn applications on the availability o...

The effect in vivo of high nutrient levels of copper (240 micromolar) on the activity of different metalloenzymes containing Cu, Mn, Fe, and Zn, distributed in chloroplasts, peroxisomes, and mitochondria, was studied in leaves of two varieties of Pisum sativum L. plants with different sensitivity to copper. The metalloenzymes studied were: cytochrome c oxidase, Mn-superoxide dismutase (Mn-SOD) ...
Levels of the heavy metals Copper (Cu), Zinc (Zn), Lead (Pb), Cadmium (Cd), Chromium (Cr), Nickel (Ni), Iron (Fe) and Manganese (Mn) were determined by graphite furnace atomic absorption spectrophotometer (Model 67OG) in coastal water, sediments and soft tissues of the Saccostrea cucullata, from the intertidal zone at five stations in the Gulf of Chabahar on the Iranian coasts along the Oman Se...
in the paper, the contents of calcium (ca), magnesium (mg), zinc (zn), copper (cu), iron (fe),manganese (mn), chromium (cr), lead (pb), cadmium (cd), aluminium (al), and nickel (ni) were determinedin the meat of roe deers, wild boars, and hares coming from central region of poland. measurements werecarried out using atomic absorption spectrometry. the ranges of median values found for the conce...
