  • Experiments on cable strumming and flow induced drag

    Creator:
    Barnes, Bert Lee
    Abstract:
    Short non-flexible elements of cable were driven harmonically in water while constrained by springs. The cable elements were observed to oscillate at approximately the Strouhal vortex shedding frequency. Damped resonance occurred near the point where the natural frequency and the Strouhal vertex shedding frequency were equal. Transverse oscillation amplitudes greater...

  • Polymorphic, sympatric flavonoid variants of Claytonia perfoliata Donn from the Columbia River Gorge

    Creator:
    Miller, John M.
    Abstract:
    Claytonia perfoliata is a west-American polyploid complex of common annuals (x=6). The species is polymorphic; exomorphic characters are often variable within local populations. In a transect of the Columbia River Gorge diploids, tetraploids, hexaploids, octoploids, and decaploids were collected, which varied in shape of basal and cauline leaves, degree of...

  • Donor centers in vanadium pentoxide

    Creator:
    Yerke, John Fredric
    Abstract:
    The dielectric relaxation of V₂ 0₅ was investigated using the method of Davidson and Cole. By means of an Argand diagram, deviation from an exact Debye dielectric was established. This was done with the parameter β. For a Debye dielectric β= 1. The largest value of β for V₂O₅ was...
