Phosphate, silicate and nitrate concentrations in the sea off
the coast of Oregon were determined to study their seasonal distribution
patterns. The water samples were collected monthly along the
east-west hydrographic line off Newport, Oregon, from the shore to
165 miles (310 km) offshore. The samples were analyzed by both...
Three seismic refraction profiles obtained between 42°N and
43°N along the median valley of the Gorda Ridge, an active spreading
center, allow the computation of the velocity structure underlying the
valley. Wide angle reflections which appear on the seismic records
suggest the existence of a velocity inversion underlying layer 3...
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...
The concept of a prestressed cylindrical shell was investigated. In particular, a cylindrical shell constructed from coiled pressurized tubing was analyzed. This analysis was concentrated in two main areas, the first involved the failure modes of the prestressed cylinder. Both the buckling and yielding behavior of the tube walls was...
Wind speed data were taken at a weather station on the coast
and horizontal wind speed energy spectra were computed. The shape
of an average spectrum obtained in marine environment is compared
with an average land spectrum and the presence of a spectral gap is
observed in the shoreline spectrum....
This study was undertaken to increase knowledge of opal phytoliths
in plants and soils of Oregon, and thus encourage further use of
phytoliths in future pedologic investigations.
Content of plant opal in needles from ten common Oregon conifer
species ranged from 0.2 to 7.9%. Western larch (Larix occidentalis)
contained the...
