Negative ion formation by charge exchange between hydrogen and cesium

The close coupled equations provide low-energy cross sections which are in good agreement with the experimental values.     

An Approach to the Control of Bed Occupancy in a General Hospital

Journal of the Operational Research Society - An examination of the problems of controlling bed occupancy in a General Hospital suggests that many common assumptions may need to be revised. The...     

Exchange interactions in solid 3He

An outline is given of the extension to ³He of a new method for treating exchange. It is shown that indistinguishable particles can be equivalent to localized distinguishable particles. The exchange interactions do not take the Heisenberg form.     

THE FLUORESCENCE OF CAROTENOIDS

Abstract The carotenoids β-carotene, lutein, lutein epoxide and violaxanthin are fluorescent compounds. Upon excitation around 280 mμ, at wavelengths close to those of their ultraviolet absorption maxima, these carotenoids fluoresce within the range 300–400 mμ, with maximal fluorescence at approximately 320–340 mμ.     

Family physicians' beliefs about genetic contributions to racial/ethnic and gender differences in health and clinical decision-making

Greater attention towards genetics as a contributor to group health differences may lead to inappropriate use of race/ethnicity and gender as genetic heuristics and exacerbate health disparities. As part of a web-based survey, 1,035 family physicians (FPs) rated the contribution of genetics and environment to racial/ethnic and gender differences in health outcomes, and the importance of race/ethnicity and gender in their clinical decision-making. FPs attributed racial/ethnic and gender differences in health outcomes equally to environment and genetics. These beliefs were not associated with rated importance of race/ethnicity or gender in clinical decision-making. FPs appreciate the complexity of genetic and environmental influences on health differences by race/ethnicity and gender.
