Many agricultural fields are burned in the Willamette Valley
of Oregon during the summer for economic reasons. A major air
pollution problem results from these burnings. The purpose of this
study was to develop relations between the maximum plume height
and some of the independent variables affecting this plume height,...
The selenium-responsive syndromes and the discovery of
Factor 3-selenium focused attention on selenium in metabolism. Two
hypotheses have been advanced to explain the metabolic effect of
selenium: 1) substitution or sparing of alpha tocopherol, and 2) a
primary role in metabolism. The first hypothesis is supported by
Scott and Desai,...
The feeding habits of the lanternfishes Tarletonbeania crenularis, Diaphus theta and Stenobrachius leucopsarus were studied by analyzing 1,735 stomachs from 54 collections from the slope waters off Newport, Oregon. Forty-one taxa of food items were identified. Euphausiids
(Euphausia pacifica), copepods (Calanus spp. and Metridia lucens) and amphipods (Parathemisto pacifica) were...
To observe the effects of oviposition as related to time of insemination
on fertility, four trials were conducted in which individually
caged White Leghorn hens were artificially inseminated with 0.05 cc
of undiluted mixed semen obtained from 4 to 5 cockerels. These inseminations
were made at 9:45 a.m. , 10:00...
In the construction of a cab-over-engine semi tractor, Freightliner
Corporation of Portland, Oregon uses brackets to make the connection
between the front leaf spring mounts, bumper, front hinges
for the tilt-cab and the longitudinal frame rails. One bracket is used
on each side. The integrity of these brackets is essential...
The object of this research was to study the effect of readily
available carbohydrates (RAC) upon the utilization of urea in fattening
rations and to determine the effect upon carcass characteristics
that determine quality and yield grades. A 2 x 2 latin square designed
feedlot trial comparing urea at 0.5%...
Rates of birth, death and population change were calculated for Cyclops sp. and Diaptornus forbesi in Soap Creek Ponds V-VIII near Corvallis, Oregon during the interval April, 1968 to April, 1969. An egg ratio method was used in calculating these rates. Duration of development of the eggs of both species...
