This thesis is an engineering report on the creep behavior of
power transmission line conductors. Laboratory creep test results
are reported for Pheasant, Narcissus and Chukar conductors.
The report follows a standard nomenclature and format suggested
by the International Study Committee No. 6 of Conference
Internationale des Grands Reseaux Electriques...
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...
"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...
This thesis is a development of two sets of equations predicting the switching times of a saturated transistor. The first set of equations defines the rise, storage, and fall times at a single operating point where the transistor beta, cutoff frequency and collector capacitance are known. The second set of...
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 acute toxicity of Diquat (1:1-ethylene-2:2' dipyridylium
dibromide) and Dichlobenil (2, 6-dichlorobenzonitrile) to six selected
pond invertebrates was determined using the median tolerance limit
estimation method. Diquat was more toxic to the amphipod, Hyalella
azeteca than to the aquatic insects Callibaetis, Limnephilus,
Enallagma, Libellula, and Tendipedidae. The addition of mud...
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,...
A post-failure investigation of a highway embankment constructed
over organic and sensitive subsoils was made with a series
of field vane tests. The results indicated that the embankment was
quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...
