Discriminating Interactions Between Chiral Molecules In the Liquid-phase - Effect On Volumetric Properties

Volume changes on mixing for binary mixtures of optically active liquid compounds have been determined at 25 "C by using a vibrating tube densimeter. Six enantiomeric and six nonenantiomeric pairs of chiral molecules have been considered. In all the cases chiral discrimination appeared to produce small but significant effects (0.0024.016 cm3 mol-'). The excess molar volumes, p, of the (+) and (-) isomers of limonene, carvone, 2-methyl-1-butanol, and a-methylbenzylamine showed negative values, while VE of the enantiomers of a-pinene and 2-odanol gave positive results. Partial molar volumes, Po,fo r the investigated chiral solutes in chiral solvents have been obtained from p data. The effecta of chiral discrimination of Po have been compared with the prediction of a simple statistical approach in which discrimination arises from space-filling differences in contacts between hard surfaces

Managed Care, Medicaid & the Elderly, An Overview of Five State Case Studies

This publication contains a series of five state case studies of Medicaid managed care programs enrolling elderly care programs enrolling elderly Medicaid recipients. The case studies were prepared by University of Minnesota National Long Term Care Resource Center\u27s two partners: the National Academy for State Health Policy (NASHP) in Portland, Maine and the Institute for Health Services Research, School of Public Health at the University of Minnesota in Minneapolis, Minnesota. These case studies have been conducted under the leadership of Trish Riley and Robert Mollica at NASHP. The project was undertaken to examine the experience of elders in managed care, particularly managed care programs for low income, dually eligible elders, and the roles of aging network in relation to managed care. The site visits were conducted from November to early March and changes may have occurred since the reports were written
