building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...

Sulforaphane (SFN) is an isothiocyanate which is produced through glucoraphanin hydrolysis via myrosinase activity. In the present study, SFN content and peroxidase activity has been assessed in treated Lepidium draba seedlings with different concentrations of iron and copper during 8 and 16 hours treatment. The results showed that the SFN content drastically elevated at treatment with...

A study was conducted to determine the effects of supplementing a diet marginally deficient in copper (Cu) with iron (Fe), molybdenum (Mo), or Cu on phagocytic cell function and disease resistance of calves. Thirty-one calves were born to heifers fed a corn silage-based diet containing 4.5 mg of Cu/kg. Treatments consisted of 1) control (CON; no supplemental Cu, Fe, or Mo), 2) 600 mg of Fe adde...

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 ...

In this study, the theoretical calculations of CO dissociation were carried out on Cu-Fe alloy surface by a full-potential method, which made more accurate results especially on the prediction of adsorption energies. This process may be governed by either a direct route or a H-assisted via HCO and COH intermediates pathways. In comparison to the pure surface Fe (100), the presence of Cu atom en...
