The diffusion process in a variable density, turbulent
flow is a factor which greatly influences the waste
disposal characteristics of tidal estuaries. Waste disposal
from cities and industries, is posing an increasing
threat to the estuarine environment. Accurate prediction
of the effects of proposed waste outfalls in well-mixed
estuaries (which...
"The purpose of this report is to evaluate alternate engineering plans for the disposal of wastes from a kraft process pulp and paper mill located at Toledo, Oregon. These alternatives have been evaluated from the standpoint of estimated annual cost and estimated resulting pollution of Yaquina Estuary in order to...
Purpose of the Study
The purpose of this study was to measure, by the analysis of
statistical and subjective data, the effects of work experience programs
on disadvantaged ninth grade students.
The study involved one major hypothesis: the introduction of
work experience, as part of the ninth grade curriculum, for...
The objectives of this research were to determine the effects of various soil parameters on the reaction of Isopropyl-N-(3-chlorophenyl)Carbamate (CIPC) with a soil and to relate enthalpy values for the adsorption to chemical or physical bonding mechanisms. Six Oregon soils providing a range of pH, organic matter, clay, iron oxide,...
The abundance of copper was determined in four to six one-gram
specimens separated by a distance of several inches from each
of 23 large chondritic fragments (greater than 1 kg) via instrumental
neutron activation analysis and counting of the annihilation N-rays of
⁶⁴Cu. It is believed that an accuracy of...
Vacuum evaporated dielectrics for use in MOS structures
were studied in this research project. Dielectric
films were deposited on substrates by electron bombardment
evaporation of sapphire and quartz source materials.
These deposited films were studied using infrared spectroscopy,
index of refraction, density, and dielectric constant
measurements. Etching tests were also...
Maturation rates of monogerm sugar beet seed grown in Western
Oregon were measured quantitatively to determine attainment of maximum
seed development and germination. Seed was collected at various
intervals after anthesis from two hybrid varieties representing the
extremes in resistance (hard bolting) and susceptibility (easy bolting)
to seedstalk development. The...
Zonotrichia leucophrys gambelii is a strongly migratory race
of white-crowned sparrow that exhibits a marked deposition of fat
during the vernal migratory period. The physiological basis for fat deposition is a positive energy balance which results from a photo-periodically induced hyperphagia. Simultaneously with the increased
caloric intake there is an...
