This dissertation seeks to understand Yi farmers’ livelihoods in the midst of an agricultural transition in Yunnan, Southwest China. This dissertation examines a community’s traditional knowledge related to wild edible plants (WEPs), analyzes socio-ecological vulnerability and resilience in the face of agricultural transition from subsistence farming to cash cropping, and...
California bighorn sheep (Ovis canadensis californiana) were studied on Hart Mountain, Oregon, during the summer and fall of 1976, and the spring of 1977. The population consisted of a minimum of 196 sheep in June, 1977. The high number of lambs observed and high lamb:ewe ratios throughout both years of...
Relationship health has many benefits, from physical and emotional health of the partners to their children’s wellbeing. Early intervention programs protect relationships from decline. These programs represent growing public health initiatives. However, most studies on wellness or early intervention overlook lesbian and gay male couples. Research that assumes lesbian and...
The growth of Brettanomyces bruxellensis is a major cause of wine spoilage due tothe production of the volatile phenols 4-ethylphenol (4-EP) and 4-ethylguaiacol (4-EG), derivatives of p-coumaric acid and ferulic acid. During the winemaking process,some microorganisms can impact the concentration of the 4-EP precursors pcoumaricand coutaric acid (tartaric acid-esterified p-coumaric...
In this work we will analyze branching Brownian motion on a finite interval with oneabsorbing and one reflecting boundary, having constant drift rate toward the absorbingboundary. Similar processes have been considered by Kesten ([12]), and more recently byHarris, Hesse, and Kyprianou ([11]). The current offering is motivated largely by the...
In the U.S., childhood overweight and obesity has grown to epidemic levels. The National Survey of Children’s Health (NSCH) found that nationwide, approximately 32% of children 10–17 years old are identified as overweight, over half of them (nearly 17%) are obese. This is a concern because these rates continue to...
Many applications require not only representing variability in software and data, butalso computing with it. To do so efficiently requires variational data structures thatmake variability explicit in the underlying data and the operations used to manipulate it.Variational data structures have been developed ad hoc for many applications, but thereis little...
Old-growth forests are structurally complex in both vertical and horizontal dimensions. This complexity arises from biological characteristics, typically branch and leaf structure, but also includes epiphytes with varying form and function. I characterized the biomass and species composition of epiphytes along the vertical axis of an old-growth Douglas-fir (Pseudotsuga menziesii)...
Femtosecond stimulated Raman spectroscopy (FSRS) is an ultrafast vibrational technique which allows rapid collection of Raman spectra with simultaneously high temporal and spectral resolution. With the recent development of FSRS methodology, three FSRS techniques (conventional, tunable, and anti-Stokes) have been implemented in our laboratory to dissect the excited state structural...
The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...
Douglas-fir provides social, economic, and ecological benefits in the Pacific Northwest (PNW). In addition to timber, forests support abundant plant and animal biodiversity and provide socioeconomic viability for many rural communities. Products derived from Douglas-fir account for approximately 17% of the U.S. lumber output with an estimated value of $1.9...
Alaska pollock (Gadus chalcogrammus) is a schooling whitefish native to the Bering Sea that is prized for its fillets, surimi, roe, and milt. Fillets are frequently used for popular products such as fish and chips. If collected, roe and milt are commonly exported to South Korea and Japan. However, no...
In this thesis, I investigate the organization of eelgrass (Zostera marina L.) and mesograzer communities across local and regional scales in three upwelling- influenced estuaries located along the Oregon coast, USA. Eelgrass ecosystems are an important source of primary production in estuarine systems, providing numerous ecosystem services, including nursery habitat...
Silicon integrated circuit (IC) technology has enabled numerous electrical and optical sensors used in biological and chemical assays, where they can increase performance while decreasing cost and size compared to traditional detectors. There is significant potential to further leverage IC technology for lab-on-chip applications, creating affordable and portable medical diagnostic...
The range of different nonvolatile constituents extracted from hops in highly hopped beers suggests that iso-alpha acids may not be the sole contributor to beers’ bitterness. Among brewers producing hop-forward beer styles there is a growing concern that the Bitterness Unit (BU) is no longer an accurate predictor of beer...
Fungi play critical roles in ecosystem processes and interact with plant communities in mutualistic, pathogenic, and commensal ways. Fungal communities are thought to be influenced by both associated tree communities and soil properties. However, the relative importance of the biotic and abiotic drivers of soil fungal community structure and diversity...
Transportation systems are facing safety and operational challenges with a cost of billions of dollars annually in lost production time and wasted fuel. Infrastructure expansion, previously held as a panacea to most transportation challenges has lost its appeal due to financial, land-use and environmental constraints. Interest is surging in intelligent...
Vibrio parahaemolyticus is frequently isolated or detected from raw seafoods, especially shellfish. Also, Listeria monocytogenes, Salmonella spp. are pathogens that are frequently found in ready-to-eat (RTE) seafood, such as smoked fish and shellfish, seafood salad, cooked shrimp and crabmeat, and seafood consumed raw. Two studies to improve safety in RTE...
Traditional electronic systems are usually fabricated via printed circuit boards (PCBs). In a regular PCB, the electronic components are placed and mounted on a two-dimensional board. Such a component layout limits the freedom in the component placement process which results in larger electronic devices. With the use of Additive Manufacturing...
Significant progress has been made over the past 20 years in developing models to estimate the service-life of reinforced concrete systems. The basic understandings of the mechanisms that control the transport of ions and moisture in concrete systems have been well researched and models for determining corrosion initiation, specifically chloride-induced...
