Vacancy-vacancy, vacancy-impurity, and impurity-impurity interactions in aluminum
Physical Review B, 1974Electronic interactions between vacancies and impurity atoms have been generally studied using the pseudopotential formulation based on the second-order perturbation theory. The distortions of the lattice around vacancies and impurity atoms were conventionally neglected because of their great complexity.

The impurity-impurity interaction in aluminum
Physics Letters A, 1973Abstract The interaction between a Cu atom and a Sn atom in aluminum was calculated by the pseudopotential method. It is shown that there is a rather weak coupling between these different types of impurity atoms.

Simplified Impurity Calculation
Physical Review, 1954The methods of previous papers by the authors are applied to a simplified impurity calculation. This is the case of a localized perturbation in a simple cubic lattice. We consider the effect of the perturbation on a single band which is describable in terms of a Wannier function which only has nearest neighbor interactions.

Theory of impurity scattering: Interstitial impurities
Physics of Condensed Matter, 1975A framework for studying impurity scattering in dilute, non-magnetic, metal alloys can be developed from a knowledge of the exact electronic eigenstates of a single impurity in an otherwise perfect lattice of muffin tin potentials. Such an approach has been developed for systems in which the impurity occupies a substitutional site of the lattice, as ...

Abstract This chapter argues that dehumanization is much more complex than merely thinking of other people as lower forms of life. When people dehumanize others, they think of them as both human and subhuman at the same time, and as violating the categorical distinctions that are supposed to underpin the natural order.

Impurity-impurity interactions in dilute alloys
Hyperfine Interactions, 1990The interaction between impurities of two solute elements in metal hosts leads to a non-random distribution of impurity atoms among the lattice sites. Experimental studies of this distribution provide quantitative information on the energy involved in the formation of an individual impurity-impurity pair.

Environmental Monitoring and Assessment, 1989
Snow can be involved in the acquisition, transport, storage and release of atmospheric impurities. Because it can store impurities for periods of time ranging from hours to millenia, it provides a medium for monitoring atmospheric impurities for a wide range of time scales.In most climates, snow is involved in the precipitation process.
