Accurate and fast evaluation of electrostatic interactions in molecular systems is still one of the most challenging tasks in the rapidly advancing field of macromolecular chemistry, including molecular recognition, protein modeling and drug design. One of the most convenient and accurate approaches is based on a Buckingham-type approximation that uses the multipole moment expansion of molecula...

In this article, David Buckingham addresses the challenges media educators face in dealing with postmodern media culture. Buckingham begins by outlining the nature of contemporary developments in children’s media environments and how these relate to broader changes in their social status. He argues that these developments represent a fundamental challenge to the modernist project of media educa...

to get a mole of a gas, it is necessary to calculate the intermolecular interaction. theseintermolecular interactions can be depicted by drawing the potential energy of a pair molecule inrelation to the distance. the intermolecular potential energy surface in the mixtures of ch4-h2cogases from ab initio calculations has been explored. in ab initio calculations the basis setsuperposition error (...

As part of the Sediment Acoustics Experiment 1999 (SAX99) several researchers measured sound speed and attenuation. Those sound speed and attenuation results have been compared to the frequency dependence predicted by Biot theory. The comparisons indicate that the variation of sound speed with frequency is well modeled by Biot theory as frequency increases, but the variation of attenuation with...
