Conversion of solar energy to mechanical power through the use of
thermostatic bimetals and linear Fresnel lenses was found to be both
theoretically and experimentally feasible. Using linear Fresnel lenses
to concentrate sunlight on bimetallic coils caused a simple sun powered
motor to produce rotational shaft power. However, continuous rotational...
The assumption of constant quartz accumulation for the deep-sea
sediment core Y69-106P, taken in the Panama Basin, has been
used to date the core and construct a sedimentation rate versus time
curve for it. Stratigraphic control for the calculated time scale
includes three carbon-14 measurements, the extinction of the
radiolarian...
The purpose of this research was to determine the effects of a
college human sexuality course upon sex knowledge, attitudes toward
sexual behaviors of non-significant others, and attitudes toward the
sexual behaviors of self and spouse. In addition, the study sought to
investigate the relationship between knowledge gain and attitude...
More than 280 species of caddisflies (Trichoptera), representing 80
genera in 16 families, are known to occur in Oregon. Detailed distribution
records within the state are given, as well as the known geographic range
for each species. Biological information, such as life cycle, habitat
preference, flight period, and larval feeding...
Early diagnosis is essential for proper management of the Marfan syndrome, yet due to diverse manifestations of the disorder, specific diagnosis is difficult. Excessive growth of the long bones constitutes a major characteristic of the syndrome; thus differences in growth patterns from those of the average child suggest a possible...
