Urea is one of the most commonly used nitrogen fertilizers in agricultural lands. The fate of this fertilizer in soils is greatly related to the soil urease enzyme activity, while this enzyme commonly exists in the adsorbed state on the surface of soil colloids, and especially clay minerals. In order to examine the kinetic properties of free and adsorbed Urease on the surface of sepiolite and v...

In recent work the structural, electronic and optical properties of BSb compound in bulk and surface (110) states have been studied. Calculations have been performed using Full-Potential Augmented Plane Wave (FP-LAPW) method by WIEN2k code in Density Functional Theory (DFT) framework. The structural properties of the bulk such as lattice constant, bulk module and elastic constants have been inv...

the present study aimed at investigating how different news agencies using the concept of legitimation/delegitimation represent the same event differently. to this end, van leeuwens (2008) legitimatory/delegitimatory framework was applied to the data gleaned from the iranian state-run news agency fars news, british state-run news agency bbc, and also american state-run news agency voa. the resu...
