The influence of canopy structure and epiphytes on the hydrology of Douglas-fir forests

Creator:: Pypker, Thomas G.
Abstract:: Canopy structure has a significant impact on the canopy hydrology of Douglas-fir forests in the Pacific Northwest (PNW). Whole canopy rainfall interception was measured for young Douglas-fir forest and compared to an old-growth Douglas-fir forest. The old-growth forest had significantly greater canopy water storage capacity (5) and direct throughfall fraction...

Cytoskeletal regulation in cell motility and invasion

Creator:: Jang, Hyo Sang
Abstract:: Cell motility and invasion are important for development, immunity, wound healing, and tumor cell metastasis. Cells on two dimensional substrates migrate in three steps: protrusion of the front end, translocation of the cell body, and retraction of the rear end. For cells to migrate efficiently, these steps need to be...

Glyphosate-resistance in Italian ryegrass (Lolium multiflorum): evaluation and investigation of the mechanisms of resistance

Creator:: Perez-Jones, Alejandro
Abstract:: A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....

Scientists' perspectives on the importance of scientific communication in natural resource decision-making

Creator:: Shaw, Christine Michelle
Abstract:: Natural resource decisions require consideration at many levels, ranging from how one invertebrate will be affected by a nearby road, to how an entire watershed will be transformed by a massive clearcut. Considerations reach farther than just the local ecological community-human communities, economies, and future impacts on the communities and...

Noninvasive Quantitative Measurement of Bacterial Growth in Porous Media under Unsaturated-Flow Conditions

Creator:: Yarwood, R. R., Rockhold, M. L., Niemet, M. R., Selker, J. S., and Bottomley, P. J.
Abstract:: Glucose-dependent growth of the luxCDABE reporter bacterium Pseudomonas fluorescens HK44 was monitored noninvasively in quartz sand under unsaturated-flow conditions within a 45- by 56- by 1-cm two-dimensional light transmission chamber. The spatial and temporal development of growth were mapped daily over 7 days by quantifying salicylate-induced bioluminescence. A nonlinear model...

Poly(vinyl alcohol) / cellulose nanocomposite barrier films

Creator:: Paralikar, Shweta
Abstract:: There is a continual interest in developing robust, flexible, durable, lightweight, waterborne polymer barrier coatings which are increasingly resistant towards both chemical warfare agents as well as an ever growing number of toxic industrial chemicals. In this study, barrier films were prepared with poly(vinyl alcohol) (PVOH) and varying amounts of...

Morality and materialism : American conservatives and science, 1945-1964

Creator:: Schefke, Brian R.
Abstract:: Following World War II, the United States enjoyed unprecedented power and prestige. The wartime alliance with the Soviet Union quickly collapsed amid mutual suspicion and fear, however, resulting in the Cold War. Science was a significant political component in that ideological conflict. In the United States, inspired by Franklin D....

Fabrication and application of polymer based microfluidic devices

Creator:: Koesdjojo, Myra T.
Abstract:: The concept of reducing laboratory operations in scale such that they fit on a microfluidic chip has been met with great enthusiasm. Lab-on-a-chip devices promise to be cost effective to operate due to reduced reagent consumption, have the potential to offer shorter analysis times due to their short path lengths,...

Cortisol, abdominal obesity, and reductions in inflammation after cardiac rehabilitation in non-diabetic coronary patients

Creator:: Ogimoto, Kayoko
Abstract:: Abdominal obesity is a part of insulin resistance syndrome that is closely linked to increased risk of coronary artery disease (CAD). Because fat tissue acts as an endocrine target and source of hormone production, increased metabolism or production of chemical messengers in fat tissue may result in metabolic perturbations that...

Tracer experiments in a non-uniform porous medium : implications of diffusive mass transfer on the late-time breakthrough behavior

Creator:: Freiherr von Schwerin, Claudius
Abstract:: Mass transfer processes were evaluated in an artificial, non-uniform porous medium with a power law distribution of diffusion rate coefficients obtained from physical characterization of solute and porous medium. Breakthrough curves of several pulse experiments conducted at different velocities were compared (1) to analytical expressions for concentrations at mass transfer...
