Metal-Organic Frameworks (MOFs) are crystalline compounds formed from reacting a metal ion with an organic ligand. They represent a promising new avenue in materials science for gas separations and storage. Certain MOFs, in particular Mg-MOF-74, have shown a strong affinity for the capture of CO2. This project investigated a known...
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...
My thesis is comprised of two articles, titled "Journeying Through (An)Other World: Examining the Role of Magic and Transformational Otherness in Sir Gawain and the Green Knight" and "Magic, Muggles, and Mudbloods: Examining Magical Otherness in J.K. Rowling's Harry Potter Series." The introduction frames the thematic, theoretical, and critical connections...
This thesis undertakes an examination of Margaret Atwood’s 1985 novel, The Handmaid’s Tale, as a layering of genres. A futuristic dystopia that imagines late twentieth-century America as having fallen into neo-Puritanism and totalitarianism following widespread infertility and violence, The Handmaid’s Tale invites contemplation of various forms of fundamentalism, radicalism, and...
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....
Glutamine synthetase activity is present in both the cytosol and
bacteroid fractions of soybean root nodules. Total activity measurements
indicate that at least 90% of the activity in nodules is located
in the cytosol. Results reported by McParland, et al. (29), showed
that many properties of glutamine synthetase from nodule...
Experiments are reported which demonstrate that a cobalt deficiency
in R. meliloti results in a decreased cytochrome content of
bacterial cells. It is concluded that the effect of cobalt deficiency
on cytochrome content of Rhizobium cells and on the leghemoglobin
content of nodules possibly may be explained by an effect...
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...
A major objective of this investigation was to determine the
possible roles, if any, of poly-β-hydroxybutyrate and products of
its metabolic breakdown in symbiotic nitrogen fixation by nodule
bacteroids. Changes in poly -β- hydroxybutyrate content and in
activities of nitrogenase, β-hydroxybutyrate dehydrogenase, and
isocitrate lyase were studied under various conditions...
