Hultine, Kevin; Bush, Sarah Elizabeth; Ehleringer, James R. | Effect of gender on sap-flux-scaled transpiration in a dominant riparian tree species: Box elder (Acer negundo) | Acer negundo is a dioecious riparian tree species with a spatial segregation of the sexes along soil moisture gradients. Females are typically more common in wet sites along streams (typically F/M = 1.6), whereas males are more common in drier sites away from streams (typically F/M = 0.6).

Miller, Jan D.; Lin, Chen-Luh | Fine coal washability-liberation analysis by cone-beam X-Ray microtomography | A new method based on cone-beam x-ray microtomography is described for direct determination of the three-dimensional liberation spectrum of multiphase particles 100 microns in size or less. Such a technique may provide the basis for more detailed and accurate washability analysis in fine coal chara... | Spectrum; Sink-float; Density | 1996 |
