This study analyzes past forest fire behavior on a selected area
in the Oregon Cascades in an attempt to evaluate level of fire hazard
on selected vegetational areas. Vegetational areas were defined in
five broad classes: Merchantable Douglas-fir Stands, Non-merchantable
Douglas-fir Stands, Oak- Madrone Stands, Non- forest
Lands, and Non-stocked...
The relationships of several wood quality traits with seed origin
and phenological characteristics, measured at a young age, were
tested from six seed sources in a young Douglas-fir (Pseudotsuga
menziesii (Mirb.) Franco) provenance plantation. The wood quality
traits measured were wood density, uniformity of wood density,
percentage latewood, fiber length,...
Ozone, present in the earth's atmosphere, filters incident solar
ultraviolet radiation such that only a portion of the total ultraviolet
spectrum emitted by the sun reaches the planet's surface.
Violation of the integrity of this filter could mean an alteration in
the solar ultraviolet radiation penetrating the atmosphere. Atmospheric
increases...
The Oregon sockeye salmon virus (OSV) was isolated from
diseased sockeye salmon (Oncorhynchus nerka) fingerlings in 1958
by J. L. Fryer. Experimentation performed prior to the research
reported herein indicated that the OSV contained essential lipids, was
100 to 300 mμ in size, and possessed RNA (presumptively identified
by 5-bromodeoxyuridine...
The binding of estrogen to endometrium and uterine arteries of the ewe was investigated by use of a [³H]estradiol exchange assay and by incubating whole tissue aliquants with [³ H]estradiol, a method which permits quantification of bound estrogen translocated from the cytoplasm to the nucleus. Five ewes were necropsied on...
