Seven sites of uniform topography and soil were selected within
a self perpetuating ponderosa pine forest found on the eastern
flank of the central Oregon Cascades. These plots were located along
a vegetational gradient caused mainly by an orographic rain shadow.
Data gathered included density, frequency, and cover for all...
Twenty sites of uniform topography and soil were select ed in the
montane forest found on the East flank of the Central Oregon Cascades.
These sites were located along a vegetational gradient composed of
five plant communities: Abies/Pachistima, Pinus/Ceanothus, Pinus
Arctostaphylos-Purshia, Pinus/Purshia/Festuca, and Juniperus
Festuca. An attempt was made to...
A study was undertaken in Yaquina Bay, Oregon during the
summer of 1964 to determine the distribution and the factors affecting
the distribution of the polychaete worm, Nephtys caecoides,
Hartman, 1938, in the estuary.
This organism has a continuous distribution from offshore to
a point approximately eight kilometers into the...
Polychaete annelids from 48 benthic samples containing over
2000 specimens were identified. Samples were taken with either an
anchor dredge or an anchor-box dredge from a 15 station transect
(44° 39. 1'N) that ranges from 800 to 2900 meters in depth. Sediment
subsamples were collected and analyzed for organic carbon...
Samples of benthic organisms off the coast of Oregon, taken
from depths varying from 50 to 2900 meters, have been analyzed in
terms of diversity at a given station, and similarity and ecological
distance to other stations. Estimates of epifauna abundance were
also made. In the analysis an important distinction...
Controllable parameters in a power system include generator
terminal voltage, generator input power and network admittances.
These parameters can be controlled to damp
mechanical rotor oscillation in the generators and thereby
improve system transient stability. Explicit equations are
derived in this thesis for the control of these parameters to
introduce...
The catabolism of glucose by proliferating and resting cells of
two strains of Saccharomyces cerevisiae has been examined, with
respect to the nature and participation of concurrent glucose pathways
by means of the radiorespirometric method. The nicotinamide
nucleotide content, and nicotinamide nucleotide oxidase activities
in these cells were also examined....
