Forty-eight young adult males were ranked on the basis of mean
hand-grip strength scores and the middle one-third, the medium
strength range, were chosen as subjects. These sixteen subjects were
given 30 serial trials in each of four tests; knee flexion, knee
extension, elbow flexion, and elbow extension. Each trial...
My objectives were to: 1) develop a point count technique for estimating relative
abundance of band-tailed pigeons (Columbafasciata monilis), 2) determine the
availability, distribution, and interspersion of mineral sites, and nesting and foraging cover in relation to abundance of band-tailed pigeons in west-central Oregon, and 3) test the hypothesis that...
Forty-two fall-calving crossbred cows were equally
allotted to six pens of seven cow-calf pairs each. Two
treatments (0 and 200 mg lasalocid/head/day) with three
replications were used to determine the effects of
lasalocid on fall-calving beef cows. The cows were fed
grass hay, haylage and pasture ad libitum. The cow-calf...
Sialic acids are involved in many cellular interactions. They can serve as an adhesion ligand or act as an inhibitor to cellular adhesion by charge repulsion or by masking potential ligands. Although sialic acids are implicated in the process of blastocyst implantation, their expression and regulation in uterine epithelium of...
Non-point agricultural contaminants, such as nitrogen, may lower groundwater quality and thereby impose health and environmental risks. The objective of this study is to evaluate tax policies to control agricultural pollutants in a spatially heterogeneous and dynamic setting. The focus of the study is non-point source nitrate contamination of groundwater...
Several lactic acid bacteria (LAB) of the Lactococcus, Lactobacillus,
Leuconostoc and Pediococcus genera were screened for inhibition of
food-borne pathogens and spoilage microorganisms in raw milk and
dairy products. Listeria monocytogenes was killed by Lactococcus
lactis subsp. lactis and Pediococcus pentosaceus due to their
production of bacteriocin-type inhibitors. Staphylococcus aureus...
In the past 3-5 years, two federal agencies, the Forest Service (FS) and the National Park Service (NPS), have initiated pilot programs in concessioner-operation of developed-site government recreation facilities, specifically family campgrounds and related facilities. These programs have been generally successful by agency measure, and consequently, both agencies have modified...
Previous work has shown that diuron (3-(3, 4- dichlorophenyl)-1,
1-dimethylurea) is less toxic to fall-planted wheat than to wheat
planted in the spring. Diuron has been a significant factor in increasing
yields of winter wheat grown in Oregon's Willamette Valley.
The influence of several selected environmental factors on diuron
toxicity...
There are between one and two million
occurrences of head injuries in this country each
year causing an estimated 140,000 deaths. Fifty to
seventy thousand who survive are left with such
intellectual impairment as to preclude returning to a
normal life. The purpose of this study is to
investigate the...
