Characterization of a virus requires that its physical, biochemical
and biological properties be determined. In this study the
Oregon sockeye salmon virus was characterized. It was isolated
in the fall of 1958 from juvenile sockeye salmon,...

Pine needle blight of Pinus ponderosa Laws. caused by
Elytroderma deformans (Weir) Darker is recognized by changes in
the needles, in the bark and in the development of the branches.
Anatomical studies of the host-parasite relation have been made...

The effects of x-irradiation on quantitative genetic traits was
investigated by comparing the response of irradiated mice to selection
for litter size and 28-day weight with the response to selection
for the same two traits in non-irradiated...

Research was conducted in a mixed-coniferous forest stand
that was clearcut, burned, and seeded in order to study early plant
succession, grazing influences on native and introduced species, big
game use, and environmental relationships...

In this paper a signal-processed antenna and receiver system is
proposed and analyzed. In addition, a simulation of the balanced-mixer portion of the processing system is made on a hybrid computer
to find the bandwidth limitations for the total...

A countercurrent, liquid-solids contactor was constructed,
operated and evaluated for a continuous ion-exchange operation.
The exchange of cupric and sodium ions between aqueous solutions
and Dowex 50W-X8 ion exchange resin was studied.
The...

The cereal pathogen Fusarium graminearum produces secondary metabolites toxic to humans and animals, yet coordinated
transcriptional regulation of gene clusters remains largely a mystery. By chromatin immunoprecipitation and high-throughput
DNA...

study
was
to
characterize
the
neutral
lipids
of
the
fat
body

Experiments are reported which demonstrate that a cobalt deficiency
in R. meliloti results in a decreased cytochrome content of
bacterial cells. It is concluded that the effect of cobalt deficiency
on cytochrome content of Rhizobium cells and on...

The data gathered for the study of the health status of freshmen
at Oregon State University were derived by an analysis of health history
records. These were obtained from the Oregon State University
Health Service. The years sampled were 1930,...

Morphological changes in five clonally propagated genotypes
of Agrostis L. resulting from variations in environment were
studied in six natural environments extending from southern Oregon
to northern British Columbia. These same clones were also...

Several bean yellow mosaic virus (BYMV) strains, presumably
not transmissible by aphids, were studied to determine the biological
and environmental conditions which would possibly result in aphid
transmission of these strains. Investigations were...

Virus-infected plants accumulate abundant, 21–24 nucleotide viral siRNAs which are generated by the evolutionary
conserved RNA interference (RNAi) machinery that regulates gene expression and defends against invasive nucleic acids.
Here we show...

Experiments were carried out to purify and characterize the
galactosidase of the Streptococcus lactis 7962. Purification was
accomplished using standard procedures; however the lability of
the enzyme to numerous treatments limited the techniques...

The research presented in this thesis evaluated the effects of
uranyl (UO₂⁺⁺) upon the absorption of Li, Na, K, Rb, and Cl. Due
to the biological importance of Na and K, these two ions were
studied in the greatest detail.
The results of this...

Some enzymes of the citric acid cycle and glycolytic pathway
in cell-free extracts of Vibrio marinus MP-1 were compared for
thermal lability. After one hour of moderate temperature exposure,
enzymes of both pathways rapidly lost catalytic...

Four methods for the simultaneous fabrication of
field-effect and bipolar transistors have been investigated.
The basic process involves obtaining two different
junction depths by a single diffusion. This was
accomplished by the techniques of (1)...

Knowledge of the viruses which are mechanically transmitted
from pear to herbaceous plants and the diseases they cause in pear
is not complete. This thesis discusses the means used to mechanically
transmit pear viruses, the properties of those...

Three synthesis methods for the realization of the
voltage transfer function by means of RC elements and
three different active devices are presented. These
three devices are a high-gain amplifier, a voltage controlled
voltage source (VCVS) and a...

Acetylimidazole was used to acetylate the tyrosyl residues
of insulin. The kinetics of acetylation were studied by termination of
the reaction at several time intervals, isolation of acetylated insulin
and determination of 0-acetyltyrosyl groups...

Condors and vultures are distinct from most other terrestrial birds because they use extensive soaring flight for their daily
movements. Therefore, assessing resource selection by these avian scavengers requires quantifying the availability of...
