An experimental and analytical study of negatively buoyant jets
discharged vertically upward into a crossflow current was conducted
to obtain information on the fate of oil well produced water. This
information could be used to validate and calibrate the short and
intermediate term portions of a computer model used to...
This research questions the effectiveness of newspapers as a
vehicle of environmental information by determining whether the
public attitude in Alaska towards off-shore oil exploration was
consistent with that expressed in the local newspapers. All
newspaper articles about off-shore oil exploration published in
Alaska between 1980 and May 1987 were...
Groundwater is an important resource in
Oregon. As more people depend on groundwater,
some water tables around the State are dropping,
threatening their water supplies. State law
requires that groundwater be managed as a
renewable resource, and that water tables do not
drop permanently.
Electron transport and relaxation may be substantially different in low-dimensional
systems compared to that observed in bulk material. In the present work, Monte Carlo
models are used for the solution to the Boltzmann transport equation, with scattering
rates calculated quantum mechanically for superlattice and quantum wells. Carrier
relaxation following optical...
Excessive nitrates in drinking water pose a human health threat, especially to infants. Methemoglobinemia, or blue-baby syndrome, is a potentially fatal condition that inhibits the ability of red blood cells to bind and transport oxygen. Nitrates/nitrites have also been linked to such conditions as cancer, birth defects, and behavioral and...
Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...
More efficient methods are needed for the in-situ evaluation of mass transfer parameters which describe the movement of solutes through aquifer material. The objective of this study was to develop a method for estimating diffusion rate and capacity coefficients using a single-well, "push-pull" tracer test. The method consists of the...
