Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...
The physical characteristics of continental shelf waters off
Oregon during late winter and spring of 1975 are described and compared
with observations taken previously during summer. The currents
in winter are barotropic in the monthly means while in summer
the currents are baroclinic. Alongshore current fluctuations on the
time scale...
Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...
This research involves a numerical study of the
hydrodynamics of gas fluidized beds. We use the continuum
model, treating both gas and particles as
interpenetrating continua. The motion of gas and
particles is strongly coupled by the interactions between
them. For simplicity, we only consider drag forces.
We use MacCormack's...
The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...
The use of remote sensing techniques in coastal science and engineering has rapidly increased in the past few decades. This dissertation outlines new remote sensing tools using two remote sensing technologies (lidar and X-band marine radar) along with two nearshore hydrodynamic and morphodynamic analyses supported or motivated by these remote...
This study was conducted to investigate the involvement of selenium and glutathione peroxidase in
prostaglandin biosynthesis by the ram vesicular gland.
Vesicular glands were collected from healthy intact
rams covering a wide range of selenium nutrition and were
analyzed for selenium concentrations, glutathione
peroxidase activities and levels of prostaglandin E₂...
