We examined two case studies to demonstrate the advantages of sulfite chemistry for pretreating underutilized woody biomass to produce sugars through enzymatic saccharification. In the first case study, we evaluated knot rejects from a magnesium-based sulfite mill for direct enzymatic sugar production. We found that the sulfite mill rejects are...
This study demonstrated at the pilot-scale (50 kg) use of Douglas-fir forest harvest residue, an underutilized
forest biomass, for the production of high titer and high yield bioethanol using sulfite chemistry
without solid–liquor separation and detoxification. Sulfite Pretreatment to Overcome the Recalcitrance
of Lignocelluloses (SPORL) was directly applied to the...

relatively high levels of copper by continual culture on sublethal
levels of the toxicant....
Using data collected from cannabis growers and traditional farmers, and the “Good Farmer” approach, this research provides a comparative analysis of the occupational identities of cannabis cultivators and traditional farmers in Colorado and Oregon. Though both growers and farmers within the study suggested that cannabis cultivation differed from conventional agriculture,...
Urban African American adolescents exhibit high levels of risk behavior, disproportionately high rates of sexually transmitted infections (STIs), and are at risk for acquiring Human Immunodefiency Virus (HIV). To date, interventions that address the high rates of STIs in this population demonstrate only moderate efficacy. As researchers strive to develop...
In the contemporary United States, the process of "coming out of the closet," or public disclosure of one's non-normative sexual orientation or gender identity, is ongoing and performative. Particularly within the context of dominant contemporary U.S. society, popular media favors a hegemonic set of defining characteristics, which thereby forces the...

The pulse-coupled oscillator model is widely used to simulate the dynamics of neural systems. For networks with particular internal (Mirollo-Strogatz) dynamics, I will define three broad patterns of collective behaviors found in literature in terms of inter-spike interval (ISI) statistics. These patterns are i) temporally-regular, characterized by all oscillators in...
Making quality and winterhardiness in barley are "ultimate" phenotypes composed of
component, quantitatively inherited traits. A 69-point genome map of the seven chromosomes of
barley was used, in conjunction with multi-environment phenotypes for grain yield and malting
quality, to determine the chromosome locations of quantitative trait loci (QTLs). A combined...
The incidence and duration of breast feeding were determined
via telephone questionnaires from a sample of 95 women who delivered
healthy infants during the month of September 1982, in the greater
metropolitan area of Portland, Oregon. This sample was limited in
that the women were married, predominately white, over 25...
Recent research in the UK has found that the wheat cultivar grown in the first year can have a significant impact on the amount of take-all that develops in the second year, regardless of the cultivar planted in year two. ‘Einstein’ is one such cultivar that reduces take-all disease (reduced...
Like other species interactions in ecological systems, host-pathogen interactions are influenced by environmental factors, landscape characteristics and the broader community context. My thesis explores the potential influences of food-web interactions (Chapter 2), climate change (Chapter 3), landscape structure and host movement patterns (Chapter 4), and the combined influences of local...
It is generally recognized within the brewing industry that hop aroma and flavor in beer changes as beer ages post-packaging.

Building software systems that adapt to the changing environment is challenging. Developers cannot anticipate all the changes in advance, and even if they could, the effort required to handle such situations is too onerous for practical purposes. Self Adaptive Software (SAS) adapts itself as per changing environment. The area of...
Gamma Ray Bursts (GRBs) are the most energetic explosions in the Universe, producing up to $\sim10^{53}$ ergs of energy in the first few seconds of their emission -- the so-called prompt phase that is dominated by high energy X-ray and $\gamma$-ray photons. The very large luminosities released in these events...
The function of a protein is defined by its three-dimensional structure, and in understanding the three-dimensional structure of a protein, we gain an understanding of its function and mechanism. Protein structures, especially at high resolution, can provide detailed insights into many elements of enzyme function and catalysis – identifying residues...
This dissertation is situated as the third work in a series on academic women. In 1964,
Jessie Bernard published Academic Women, which provided a comprehensive
