This contribution advances a theoretical explanation for variation in volunteering Europe—the capability approach—and tests this approach by adopting two-step strategy modeling contextual effects. approach, referring to concept of introduced Sen (Choice, welfare measurement, Oxford U...

In this paper, we used quantum chemical approach to shed light on the catalytic mechanism of γ-carbonic anhydrase (γ-CA) to convert carbon dioxide to bicarbonate ion. Density functional theory (DFT) using B3LYP and UB3LYP functional and three split-valance including 6-31G*, 6-311G** and 6-311++G** basis sets were used to calculate the details of electronic structure and electronic energy of act...
