Cheletomorpha lepidopterorum (Shaw), a predaceous, prostigmatid
mite, was studied under laboratory conditions of 20° - 30° C
and 80% - 90% R. H. to determine its effectiveness as a possible
biological control agent of Acarus farris (Oud. ), a graminivorous
mite which infests stored grains and grain products. Although
Cheletophyes...
Plant tissues contain a wide variety of phenolic compounds,
frequently in high concentration. Both non-covalent association of
intact and oxidized phenols and covalent linkage of oxidized phenols
to protein occur. Such interactions can have important biochemical
and nutritional significance.
A model system approach was used to identify and quantitate
amino...
The purpose of this study was to ascertain to what degree, if
any, there was a difference of opinion among students, parents and
faculty in regard to student behavior as that behavior pertained to
general conduct, drug use, mischief, sex offenses, drinking, cheating
and theft.
The research study was conducted...
Elodea densa Planch. was exposed to diquat (6, 7 dihydrodipyrido [1,2-a: 2', 1'-c] pyrazinediium dibromide), alone and in combination
with disodium endothall (disodium salt of 7-oxabicyclo [2.2.1]
heptane-2, 3-dicarboxyclic acid), and copper sulfate pentahydrate.
Studies were conducted in coastal lakes of Oregon infested with E.
densa. Dichlobenil (2, 6 dichlorobenzonitrile)...
Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...
Environmental swabs and meat samples from two of three seafood
processing plants sampled on the Oregon Coast were found to
contain Salmonella. Although these enteropathogens were not isolated
from the finished products, the danger of contamination is great
since the processing received by many seafoods is not designed to
yield...
Management factors used for studies on potato scab
control were evaluated for their effect on tuber russeting
and related biochemical and anatomical parameters
during 1971 and 1972.
Russet Burbank potatoes were irrigated in 1971 to
maintain high available soil moisture (between 90% and
field capacity) for 0, 3, 6 and...
Ammonium chloride aerosols of submicron size generated by
condensation and dispersion methods were treated, shortly after aerosol
charging, with shock waves originating from diaphragm pressure
ratios of up to 5.75.
The fraction of the particulate matter remaining in suspension
after a given time was measured as an indication of coagulation...
The Nearctic leafhoppers placed in the genus Sorhoanus Ribaut
by Oman (1949) were found to belong to several genera, some of
which are Holarctic in distribution. None is properly placed in
Sorhoanus as presently defined. The genera Sorhoanus, Zelenius
Emel'yanov, Boreotettix Lindberg, Lebradea Remane, and Acharis
Emel'yanov are redefined and...
