Ninety-six mature pregnant Hereford cows were allotted to three
replications with four treatments. Pregnancy was determined by rectal
palpation prior to the initiation of the study. The cows were
artificially inseminated the previous spring, beginning the end of
May, over a period of 42 days to a single Angus sire....
The marine vibrio ANT-500 is a typical psychrophile. The
growth range of the bacterium at 35‰ S is from a maximum growth
temperature of 13.5 C to a minimum growth temperature of -2.5 C
or less with the optimum near 7 C. The bacterium elaborates its
chitinase enzymes between the...
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...
As demands for major, system-wide reforms in the American welfare system are being
called for on an almost daily basis, it has become increasingly necessary to identify and
evaluate those programs which have attempted to foster a reduction in the level of public
assistance subsidies and, particularly, programs that are...
The objective of this study was to determine the relative speeds
of available medical x-ray films exposed directly to x-rays and exposed
in combination with various types of intensifying screens. The
information obtained from this sensitometric data was used to obtain
factors by which a radiographic exposure technique with one...
Escherichia coli K12, UC41 (an auxotroph) and UC175 (a wild type)
were used to determine possible relationships between binding, uptake,
and respiration and minimum growth temperature.
Both E. coli strains had a minimum growth temperature of 8.0 C in
glucose minimal medium when cells were previously grown at 15 C....
The study investigated the prescription drug
purchasing behaviors of independent retail pharmacies,
and selected pharmacy characteristics which may be related
to purchasing behaviors. The purchasing function
was considered as a major area of concern for independent
pharmacies in attempting to improve operating efficiencies,
particularly in view of increased competition
from...
The addition of catalase to culture medium increased the period
of viability of Beggiatoa from one week to two months. Addition of
catalase also produced a marked increase in cell yield and enzyme
activity. The addition of cysteine or hydrogen sulfide to the growth
medium or the use of semi-solid...
The classical dimension theories of Menger-Urysohn and Lebesgue are equivalent on metric spaces. However, their infinite-dimensional analogues may differ, even on compact metric spaces. The three such infinite-dimensional dimension theories considered in this thesis are known as countable-dimensionality, property C, and weak infinite-dimensionality. The open questions regarding the relationships between...
A historical overview of Latino enrollment in the community college is resented. Thirty Latino occupational, transfer, and non-credit students attending
an Oregon college were interviewed, examining
educational and familial background, and
college services as indicators of their
decision to pursue postsecondary studies at
the two-year institution. Results are
analyzed, supplemented...
Marginal agricultural land is currently a focus of concern for
public land use agencies in Oregon. Two approaches for evaluating marginal
agricultural lands are the Land Evaluation and Site Assessment (LESA) model
of the U.S. Soil Conservation Service, and the marginal lands criteria of
the 1983 Oregon Legislature's Senate Bill...
Purpose of the Study: The purpose of the study was to determine whether multidimensional scaling analysis could be applied to a set of perceived attitude relationships of selected community college personnel. The questions to be answered were: 1. Could perceived attitude relationships regarding the concepts of academic freedom, academic rank,...
Historically the national market for forest products has greatly
influenced the economies of Oregon and its regions because of the high
dependence of these economies on the forest products industry. With the
possibility of decreased timber production in the area and the high
probability of increasing demand for forest products...
The purpose of this study was to investigate the practices of
curriculum development in the community colleges of the western
states and make recommendations for guidelines that can be used to
plan, implement, and evaluate technical vocational programs in the
community colleges. The various functions of other organizations
concerned with...
Adequate management and scientific investigation of ecosystems
depends on classification of landscape systems based on all significant
bio-physical and associated cultural properties. The present
classification is a hierarchical systems design that can be modeled in
terms of a natural system interacting with its level-specific
environment. A watershed system in this...
Purpose of the Study: This study was undertaken as a result of interest in the
introduction of guide groups into the operation of secondary
schools. Particularly when viewed from the historical perspective
of the times in which it was initiated, the guide group concept
offers an opportunity to examine the...
Testes size as an indicator of future growth was examined
in a total of 45 bull calves from spring calves born in 1978
and 1979. Scrotal circumference measurements were used as the
physical indicator of testicle size in the live animal.
Growth traits studied were preweaning average daily gain,
weaning...
The Gorda Basin is a young oceanic plate which comes in direct
contact with the convergent margin of western North America. Two long
sonobuoy refraction profiles crossing the basin provide nearly continuous
data for computing the velocity structure of the crust and adjacent
continental slope. Time-term analysis utilizing multiple receivers...
Suicide is currently the third leading cause of death for adolescents ages 15- 24. While much attention has been given to this topic, no research has examined what specific information is being taught to pre-service school counselors. The purpose of this descriptive study was to evaluate the pre-service suicide prevention...
