Improved interpretations of the strength of the San
Andreas Fault near Parkfield, CA based on thermal data
require quantification of processes causing significant
scatter and uncertainty in existing heat flow data. These
effects include topographic refraction, heat advection by
topographically-driven groundwater flow, and uncertainty
in thermal conductivity. Here, we re-evaluate...
Knowledge of frictional resistance along faults is important for understanding the
mechanics of earthquakes and faulting. The clearest in situ measure of fault friction
potentially comes from temperature measurements in boreholes crossing fault zones within a
few years of rupture. However, large temperature signals from frictional heating on faults
have...
To initiate the defense response to an invading pathogen, plants utilize an array of immune receptors to recognize virulence effectors. Virulence effectors are released by pathogens to suppress immune responses in target hosts. These effectors are recognized by a family of resistance proteins known as nucleotide-binding leucine-rich repeat (NB-LRR) proteins....

Knowledge of the shear stress on a fault during slip is necessary
for a physically-based understanding of earthquakes. Borehole
temperature measurements inside the fault zone immediately after
an earthquake can record the energy dissipated by this stress. In the
first Wenchuan Earthquake Fault Zone Scientific Drilling Project
hole (Sichuan province,...
Wild barley (Hordeum vulgare subsp. spontaneum) could be a source of useful genes for improving cultivated barley. The useful genes present in Hordeum vulgare subsp. spontaneum may be new alleles at described loci, or these may be entirely new genes in the sense that there is limited allelic variation at...
Barley is the fourth most important cereal crop in the world because of its broad adaptation, its utility as a feedstock and for human food, and the superior properties of barley malt for brewing. Three of the most important foliar diseases of barley, on a worldwide level are: barley leaf...
Understanding complex traits is a fundamental challenge in plant genetics and a prerequisite for molecular breeding. Tools for trait dissection are markers, maps, and quantitative trait locus (QTL) analysis. Marker-assisted selection (MAS) is an application that integrates these tools. In this thesis research, a new sequence-based marker was evaluated, maps...
When Biosand filters cannot be constructed with crushed quarry rock due to resource limitations, a suitable alternative filter media is needed. In this research, two crushed quarry rock alternatives were examined. Three bench-scale Biosand filters with crushed rock, beach sand, and heat-treated beach sand media were simultaneously dosed with Willamette...
Presented in this report is an investigation of the design, construction, and operation of scaled-up cloth electrode assembly (CEA) air-cathode microbial fuel cells (MFCs). 40 mL MFCs were designed and constructed using either single or double CEAs with carbon cloth electrodes. The MFCs were evaluated using acetate media, municipal wastewater,...
