Toward biologically meaningful net carbon exchange estimates for tall, dense canopies: Multi-level eddy covariance observations and canopy coupling regimes in a mature Douglas-fir forest in Oregon

Creator:: Thomas, Christoph K., Martin, Jonathan G., Law, Beverly E., and Davis, Kent
Abstract:: We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...

Water content and electrical conductivity profile measurements for dispersive media using enhanced time domain and frequency domain models

Creator:: Flugstad, Benjamin A.
Abstract:: Water conservation and water quality are rapidly increasing in importance in all areas of the world. The ability to accurately measure soil water content and salinity, over a wide variety of conditions, is key to meeting this need. A set of forward prediction models and waveform interpretation algorithms to extract...

Surface Characterization of Engineered Biomaterials

Creator:: Faase, Ryan A.
Abstract:: The work presented in this dissertation highlights the various techniques available to characterize the increasingly complex surfaces of engineered biomaterials. The methods used range from the simple measurement of a contact angle with a smartphone to a complex synchrotron technique like near edge x-ray absorption fine structure (NEXAFS) spectroscopy to...

Development of performance based test procedures for asphalt mixtures

Creator:: Kliewer, Julie E.
Abstract:: In 1987, Congress authorized a 5 year $150 million dollar research program called the Strategic Highway Research Program (SHRP). SHRP was divided into four major areas, including the asphalt research program. The asphalt research program was divided into six major research contracts, one such contract, SHRP-003A was called Performance Related...

Cyclic nucleotides, cyclic nucleotide phosphodiesterase, protein kinase, and phosphoprotein phosphatase in the central nervous system of Manduca sexta

Creator:: Albin, Edward Elmo
Abstract:: Adenosine 3', 5' -cyclic monophosphate (cyclic AMP, cAMP) and guanosine 3', 5' -cyclic monophosphate (cyclic GMP, cGMP) were quantitated in the central nervous system (CNS) of the insect Manduca sexta by competitive protein binding techniques. The M. sexta CNS was found to contain a strikingly high level of cGMP, about...

Characterizing the neutron spectra in various irradiation facilities within the Oregon State University TRIGA ® Reactor

Creator:: Ashbaker, Eric
Abstract:: The Oregon State University TRIGA® Reactor (OSTR) has a number of irradiation facilities providing a wide range of neutron energies and fluxes. These facilities include a pneumatic transfer tube, a rotating rack, a thermal column, four beam ports, in-core irradiation tubes, a clyogenic gas transfer system and a large vault...

A comparison of two methods of divergent mass selection for heading date in two winter wheat (Triticum aestivum L. em Thell) crosses

Creator:: Frederickson, Leslie John
Abstract:: Responses to two cycles of mass selection for heading date, followed by selfing or intermating, were studied in two diverse winter wheat (Triticum aestivum L. em. Thell) crosses. Selection was bidirectional, resulting in early and late populations for each mating system, cycle, and cross. The influence of mass selection for...

Impact of Dairy Manure Digestate on Microbial Activities in Soil

Creator:: Waggoner, Ashley L
Abstract:: Amendments and fertilizers applied to optimize crop production and improve soil health also supply inputs of soil organic matter (SOM) and nutrients that affect soil microorganisms. In the dairy-intensive Pacific Northwest, dairy manure is stored as slurry mixtures until conditions are appropriate for soil application. During storage, the manure begins...
