Ehleringer, James R.; Cerling, Thure E.; Dearing, Maria-Denise | Experimental study of carbon-isotope fractionation between diet, hair, and feces of mammalian herbivores | The carbon-isotope composition of hair and feces offers a glimpse into the diets of mammalian herbivores. It is particularly useful for determining the relative consumption of browse and graze in tropical environments, as these foods have strongly divergent carbon-isotope compositions.

Olson, Randall J.; Coldwell, Karin D.; Compton, Bruce J.; Giddings, John C. | Sedimentation field-flow fractionation: a method for studying particulates in cataractous lens | It is shown that the technique of sedimentation field-flow fractionation (sedimentation [sed] FFF) can be used to determine the particle content and particle size distribution of normal and cataractous lenses. A 31-year-old normal human lens, for example, showed a particle content of 1.5% by weight ... | Fractionation; Cataractous Lens; Particulates | 1984 |
