The central purpose of this study was to develop a model for
the examination of productivity in Adult Basic Education. To that
end, an instrument developed for use in the field of business was
adapted for use with an educational audience. It examined the
relationship of adult education staff decision...
Eighteen multiparous, high producing (7,836 kg 4%
FCM) Holstein dairy cows were assigned randomly to iso-
.
caloric rations containing either 12 or 23% crude protein
(CP) on day 40 postpartum. After a 10-day adaptation
period, uterine secretion and blood samples were collected
on the day of estrus (day 0-1),...
The purpose of this study was to develop a marine bioassay
procedure using eggs and larvae of Pollicipes polymerus, a stalked
barnacle common on the west coast of North America.
A series of experiments were run to determine optimal culture
conditions for the eggs, to see if they could be...
The ocean fishery is an example of a common property
resource industry. Behavior of commercial fishermen is
determined by a complex set of economic, environmental and
social factors. All of these factors contribute to the
individual fisherman's success.
Fishermen learn to cope with the variability inherent
to their occupation. Two...
Uses of travel time and mode of transportation in selected two-parent,
two-child Oregon households was researched in this study.
The relationship between a number of demographic characteristics
and amounts of travel time as well as mode of transportation was
also examined.
The study used the Oregon data from the Northeast...
Several compounds have been shown to induce the mixed function
oxidase enzyme system of animals, and also to inhibit tumor formation.
Included in this category are several vegetables and isolated
vegetable components from the Cruciferae family. In this
study rainbow trout were fed blanched freeze-dried cauliflower,
broccoli, or Brussel sprouts...
The central purpose of this study was to examine
physicians' attitudes and communication methods which
they used with deaf patients. This study was conducted
with 100 physicians practicing medicine in Linn and
Marion counties in Oregon.
Attitude was measured by the Attitude Toward Deaf
Persons Scale and was compared to...
The objectives of this study were to (1) describe
physical environmental conditions and species composition
at several sites along an Upstream/downstream gradient in a
number of tributaries of the Willamette River in western
Oregon; and (2) identify possible relationships between
species distributional patterns and physical habitat
parameters using detrended correspondence...
A high performance liquid chromatography (HPLC)
procedure using a LiChrosorb-NH₂ column and a eluant
buffer of 75:25 (v/v) of acetonitrile:0.05 M KH₂P0₄, pH
5.95, was developed for the successful separation and
determination of ascorbic and erythorbic acids in selected
food samples.
Application of the method, which is sensitive, rapid
and...
An airgun refraction line along the length of the caldera of Axial Seamount as
recorded by three Ocean Bottom Seismometers has been analyzed using the tau-zeta
inversion technique (Dorman and Jacobson, 1981). Five resulting velocity profiles
show that the seismic velocities of the upper 1.4 km of the crust are...
Perennial ryegrass (Lolium perenne) - white clover
(Trifolium repens) hill-land pastures were grazed at
different times in the winter to study the effect of time
of winter grazing on plant response and forage production.
The same pastures were grazed by sheep once in early
December, January, February, March, or April...
The effects of L-ascorbic acid, thiamine HC1, or L-cysteine on
acetaldehyde blood levels and disposition were investigated in acetaldehyde-
treated rats. Rats were treated with ascorbic acid (2
mmoles/kg), thiamine (0.24 mmole/kg), or cysteine (2 mmoles/kg) one
hour before the administration of acetaldehyde (6 mmoles/kg). The
results show that each...
Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
Hand-defoliation was evaluated for its ability to
simulate herbivory by cinnabar moth larvae, Tyria
jacobaeae (L.) (Arctiidae) on the weed tansy ragwort,
Senecio jacobaea L. (Asteraceae). The evaluation was done
on a field population of flowering ragwort, for three
different timings (early, middle, and late season) of
damage.
In the...
Atlantic menhaden, compared to gulf menhaden, exhibit
a life history pattern that appears to be adapted to a more
unpredictable reproductive environment. From experiments
on laboratory-reared eggs and larvae, Atlantic menhaden have
larger eggs with larger yolk volume. They are larger at
hatching, utilize their yolk faster, begin feeding at...
