  • Automation of a low-temperature calorimeter

    Creator:
    Beyer, R. P. (Richard P.)
    Abstract:
    An adiabatic calorimeter operating over the range 5 to 300 K has been automated. Instrumentation includes computer controlled data acquisition, a low-thermal emf multiplexer for switching low-level dc signals, and automatic analog shield controls. Temperature measurements are made with platinum and germanium resistance thermometers, and the thermometer resistances are determined...

  • Shear stress transfer between roots and soil

    Creator:
    Commandeur, P. R.
    Abstract:
    Mass wasting events are a principal form of erosion that occurs on steep forest land throughout the Pacific Northwest. Numerous studies have reported that tree roots help stabilize steep forest land. A complete understanding of the mechanism by which roots strengthen soil would enable modeling to more closely approximate field...
