The stability of small oscillations of the troposkeinshaped
blade used on Darrieus wind turbines is investigated.
The blade is assumed to be attached to a perfectly rigid rotor
shaft and spinning in still air. Linear equations of motion are
derived which include the effects of in-plane, out-of-plane,
and torsional stiffness,...
This thesis includes four separate studies. The first two studies assessed edge effects in a
700-year-old forest. After 20 years of exposure, epiphyte assemblages on the clearcut edge
were similar to those of the forest interior, but there were some differences in vertical
distribution patterns. Several species restricted to the...
The purpose of this study is to explore experiences of professional growth for mid-career community college faculty. The research question that guided the study is: How do community college faculty members experience professional growth at mid- career? The research design included an interpretive social science methodology and phenomenological method. Nine...
It is not unusual to see stranded or washed-up marine animals and birds along any
coastline. Various networks nationwide exist to report marine mammals and sea birds,
yet, we have been unable to find a network in Oregon or nationally to report other
stranded marine animals, namely fish, cephalopods, and...
The lentil strain of pea seedborne mosaic virus, PSbMV-L, was
distinguished from the standard isolates of PSbMV by a natural inoculum
reservoir in lentil seed and by separate resistance genes in Pisum
and Lens. PSbMV-L was intermediate in symptom severity between the
standard and New Zealand isolates of PSbMV.
