The effect of different oxygen atmospheres on growth, energy
charge and enterotoxin production of Staphylococcus aureus was
investigated. Three atmospheres, air, 5% oxygen in nitrogen and
20% oxygen in nitrogen, were tested on three strains producing
enterotoxins A, B and C. Colony forming units (CFU), dry weight,
dissolved oxygen, pH,...
Two methods for the estimation of non-esterified fatty acids in
plasma were evaluated. An attempt was made to obtain a reliable
micro-technique to estimate these acids in blood fractions.
The titrimetric method of Trout et al. was satisfactory in the
analyses of pure fatty acids and fatty acids added to...
Graduate teaching assistants (GTAs) from science, technology, engineering, and mathematics (STEM) are important in the teaching of undergraduate students (Golde & Dore, 2001). However, they are often poorly prepared for teaching (Luft, Kurdziel, Roehrig, & Turner, 2004). This dissertation addresses teaching effectiveness in three related manuscripts:
1. A position paper...
The study was a creative endeavor in which researchfindings from the areas of medicine, mental health andeducation concerning effects of background music were combinedinto an experimental musical form designed to promote andfacilitate the relaxation response. This experimental musicwas cormared with Baroque largo musical background, as recommendedin Lozanov's method of accelerated...
The study determines and compares the characteristics of
innovators (defined as purchasers of wood furniture of similar
line, curve, mass, function, and cost).
Null hypotheses were written predicting that there would be
no difference between innovation in purchase of furniture and age,
creativity, social participation, socio-economic level, exposure
to mass...
The effects of oligoribonucleotides of identical or similar sequences to a
ribosomal protein binding site, specifically S8, on prokaryotic 30S ribosomal assembly
were investigated in Escherichia coli. The oligoribonucleotides were expected to bind to
the target protein S8 and block its incorporation into the 30S subunit, resulting in a nonfunctional...
This thesis study attempts to differentiate between attention and
understanding as separate phases of communication theory. To do this,
additional analysis was made of data already gathered from a random
sample of Oregonians by the Survey Research Center at Oregon State University.
An additional objective was to determine the role...
The purpose of this study was to examine the effect of a course in
assertiveness training on internalized shame in college students to determine
if assertiveness training was effective in decreasing the feeling of shame in
undergraduate college students. Assertiveness training was selected as the
treatment to reduce shame because...
Computer decision aids can help integrate and apply diverse sources of information and expertise to problems of integrated pest management (IPM) in agriculture and forestry. AppleMgr combines a rule-based expert system with databases and spreadsheets in a prototype decision aid intended to be expanded and modified for use by extension...
