The purpose of this study was to determine the effect of clearcut logging on stormflow by analysis of characteristic parameters of individual storm hydrographs. Parameters considered included height-of-rise, peak discharge, volume and time-to-peak. The hydrologic data were derived from experimental watersheds of the Alsea Study located in the Oregon Coast...
The object of the present study was to investigate the stimulatory
or inhibitory effects of barium, boron, bromine, cadmium,
chromium, cobalt, copper, fluorine, iodine, iron, manganese,
molybdenum, nickel, rubidium, selenium, strontium, vanadium, and
zinc upon in vitro rumen microbial activity as measured by the amount
of cellulose digested. Washed suspensions...
The use of the exponential-transfer-characteristics of a transistor
junction as a means of giving a logarithmic sweep calibration to a
sampling oscilloscope is presented. The prior work in logarithmic
converters leading up to the use of the transistor's transfer properties
is explored. A circuit adapting a sampling oscilloscope to a...
Soils developed on volcanic ash exhibit several unique properties
not commonly observed in soils formed on other geologic
material. Low thermal conductivities, low volumetric heat capacities,
slow transport phenomena, excess macro-drainage and
development of unique suites of clay minerals are some properties
thought to be directly related to the vesicular...
The purpose of this study was to explore the housing expenditures
and factors in, housing selection and satisfaction of single
adults. The population tested was guests and members of two single
Catholic adult clubs in Portland, Oregon. Questionnaires designed
for collecting the data for the study were mailed to the...
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...
The benthic microalgae of sediments of the two tidal flats in
Yaquina Bay, Oregon were investigated to determine the environmental
factors limiting the abundance and the horizontal and vertical distribution
of these organisms. The Southbeach tidal flat which is under the
marine realm of deposition consists of fine to medium...
The physiologic specialization of nine isolates of stripe rust
(Puccinia striiformis West.) collected in the Pacific Northwest
was determined. The separation of races was based on the differential
susceptibility of the following wheat varieties: Cappelle
Desprez, Chinese 166, Dippes Triumph, Druchamp, Etoile de
Choisy, Flamingo, Gaines, Golden, Ibis, Leda, Michigan...
This thesis is concerned with the detailed derivation
of Sheppard's Correction Formula relating the true to the
raw moments by the use of Euler-MacLaurin formula. Special
moment relationships have been derived using different
special functions, whose application is made to derive correction
formula for the semi-invariants. Special investigation
is carried...
