The one-dimensional model of Lippincott and Schroeder for hydrogen bond has Been re-examined and it has been shown that O-H bond distance depends on repulsive van der Waals and attractive electrostatic potentials.it has been shown that constant b in the van der Waals repulsion potential is not transferable to all hydrogen bonds. The possibility of obtaining the semi-empircal parameters i...

De Groot proved that every group is the autohomeomorphism group of some metrizable space. A space is totally disconnected if every connected subset of it contains at most one point. We prove that every separable metrizable totally disconnected topological group is topologically isomorphic to the autohomeomorphism group of some separable metrizable space, when given the compact-open topology. It...

Intergenerational coresidence is generally viewed as an adaptive living arrangement for both parents and their adult children facing economic constraints. Yet despite the importance of socioeconomic characteristics in predicting living arrangements, racial and ethnic differences persist. In this paper, we demonstrate that much of the race and ethnic variation in living arrangements is attributa...
