Equilibrium data for the sucrose-potassium chloride-water
system were taken for Dowex 50 W X 4 resin at 90° C. The sugar
concentration was varied from 0% to 60% by weight, and the salt content,
from 0% to 6% by weight. Because shrinkage of the resin due
to salt absorption was...
Two populations of the pine needle scale, Phenacaspis pinifoliae
(Fitch), were studied. One population was located in Corvallis,
Oregon, and the other population was located near Santiam Pass,
Oregon. Both populations were feeding on Pinus contorta.
The Corvallis population was unisexual, univoltine, and over
wintered as both eggs and adult...
Interest in the distribution of Clostridium botulinum type E
was heightened by the sudden outbreak of human botulism from
smoked whitefish chubs and canned tuna fish in 1963. The question
arose as to how widely the organism is distributed among fish
and shellfish in the Northwest and what potential hazard...
The purpose of this research was to determine if a basic protein
was associated with the DNA of Bacillus subtilis W168, and to determine
if there was a difference in the amount and type of protein
associated with the DNA at different times during the growth cycle
of the organism....
Damping-off of table beets is of widespread occurrence in the
Willamette Valley of Oregon. Pythium ultimum Trow., Pythium
debaryanum Hess., and Rhizoctonia solani Kuhn. were found to be the
important pathogenic fungi causing the disease.
Trichoderma viride, Penicillium spp. Streptomyces spp. and
certain isolates of bacteria, all saprophytic organisms associated...
A quantitative comparison was made of the incorporation of 14, C¹⁴ lipid compounds into Lee influenza virus. The compounds tested were either lipids reported to be present in the virus or precursors to virus lipid components. Infected chorioallantoic tissues were incubated in medium containing the C¹⁴ metabolites. The virus was...
