Structure and magnetism of bulk Fe and Cr: from plane waves to LCAO methods.

Magnetic, structural and energetic properties of bulk Fe and Cr were studied using first-principles calculations within density functional theory (DFT). We aimed to identify the dependence of these properties on key approximations of DFT, namely the exchange-correlation functional, the pseudopotential and the basis set. We found a smaller effect of pseudopotentials (PPs) on Fe than on Cr.

[Geography of diabetes (1960-1970-1980)].

Crude death rates show great discrepancies in diabetic mortality between industrialized and developing countries, the latter being less affected by diabetes mellitus. Nevertheless, when age is controlled, the gap becomes much narrower. For instance, the crude death rates in males by diabetes mellitus rise to 20.
