Two separate studies were conducted during this research
project. Oysters were irradiated with 500 and 1000 rads and 5, 10,
20, 50, 75, 100, 150, and 200 krads in the first study in order to
determine the effects of ionizing radiation on survival and growth
rates. Two periods of high...
Pastures consisting of mixtures of subclover (Trifolium
subterraneum) and grasses have responded to sulfur fertilization
on many sites in Douglas County, Oregon. The objectives of this
study were to examine specific changes in forage quality which occur
as sulfur is applied in excess of the amount required for maximum
yield...
Sediment samples were collected from eight sampling sites
along the Yaquina Estuary, Oregon from Yaquina Bay to Elk City near
the head of the estuary. Samples were collected in November 1973,
February 1974, May 1974 and August 1974 from two or three intertidal
levels depending on the magnitude of the...
Sixteen secondary school health teachers evaluated their own
course teaching performance. Students in each of these courses
evaluated the same teacher and the results were compared. An
adapted version of a teacher rating form developed by the School of
Agriculture, Oregon State University, was used by all study participants.
Teacher...
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 effects of improved oral hygiene on the nutrition of 23
elderly institutionalized men and women were investigated. An experimental
group of 12 received professional oral hygiene treatments
three times weekly for a period of five weeks, while a control group
of 11 received only placebo work. Changes in taste...
Intramolecular cyclization of organometallic compounds represents
a promising tool for synthesis in general. The use of strategically-
placed heteroatoms in the cyclizing molecule can influence
the stereochemistry and/or efficiency of an organometallic cyclization
while providing for functionality in the cyclic product.
The work described herein first concerns cyclizations of organolithiums....
