A Stream Reach Inventory and Channel Stability Evaluation procedure has been used to assess the nature and extent of erosional nonpoint sources of pollution in the Evans Creek basin, a tributary to the Rogue River, in southwestern Oregon. The study is based upon the results of the Oregon Department of...
This thesis examines depictions of medievalism in three central texts: Sir Walter Scott's Ivanhoe, Mark Twain's A Connecticut Yankee in King Arthur's Court, and George R.R. Martin's A Game of Thrones. Each of these texts provides an entry point for exploring the ways in which English and American writers have...
H₂-uptake positive strains (122 DES and SR) and H₂-uptake negative strains SR2 and SR3 of Rhizobium japonicum were examined for ribulosebisphosphate (RuBP) carboxylase and H₂-uptake activities during growth conditions which induced formation of the hydrogenase system. The rate of ¹⁴CO₂ uptake by hydrogenase-induced cells was about six times greater in...
The effects of rise-time and frequency on the auditory brainstem
response were studied in six normal hearing adults. Stimuli were
high-frequency gated tone-bursts with center frequencies of 8, 10,
12, and 14 kilohertz (kHz). Examined rise-times were .1, .25, .5,
and 1.0 milliseconds (msec). Duration was maintained at 2 msec....
The purpose of this study was to determine the effects
of providing behavioral objectives prior to instruction on
the achievement of students in a one-semester college
general chemistry course and to determine the effect of
providing behavioral objectives of selected chemistry
experiments in the acquisition of achievement associated
with laboratory...
The purpose of this investigation was to determine if either of
two selected commercial games, when used by seventh-grade mathematics
teachers, would significantly improve students' (1) attitudes
toward mathematics, (2) quantitative cognitive abilities, and (3) nonverbal
cognitive abilities.
Equations, a mathematics game, and Tac-Tickle, a strategy
game, were chosen as...
Ribonucleotide reductase from Rhizobium meliloti has been
partially purified and characterized. The enzymatic reduction of
ribonucleotides to deoxyribonucleotides is dependent upon B₁₂ coenzyme
and dihydrolipoate.
B₁₂ coenzyme was more effective than B₁₂ coenzyme analogues
in the reductase reaction. The affinity of the R. meliloti
reductase system for B₁₂ coenzyme was...
This project is a personal exploration of happiness and optimism through the lens of a queer and transgender subject who experiences gender dysphoria, depression, and suicidality. Taking inspiration from Ann Cvetkovich’s (2012) Depression: A Public Feeling, this work incorporates both analysis of affective theory, especially Lauren Berlant’s theory of cruel...
The purpose of the study was to analyze and compare the teaching
styles of a trial group of junior secondary science teachers
trained to use and using new materials, and a control group of teachers
using traditional materials. The new materials consisted of portable
science kits, demonstration apparatus, teacher's guides,...
