Is Advection Important? An Examination of the Advective Dynamics of Sensible Heat and Their Influence onSubcanopy Carbon Fluxes in Heterogeneous Terrain

Creator:: Carrigg, Sean Stephen
Abstract:: Abstract Understanding small-scale bio-atmospheric interactions is becoming increasingly important as the global climate continues to change at breakneck speed. A theoretical model of the sensible heat budget of a forest is developed combining conservation equations and concepts from fluid dynamics. Budget components are computationally evaluated using micrometeorological data taken during...

Bright air : geoprocessing thermal imagery to map the nocturnal dynamics of the boundary layer in a mountain valley

Creator:: Johnson, Christopher
Abstract:: A thermal infrared (TIR) camera is used to remotely sense the foliage temperature in a mountain valley. The foliage temperature is used as a proxy for air temperature and can be used to study and map the dynamics of the nocturnal, weak-wind boundary layer in this valley. All radiative flux...

Soil respiration flux in response to soil temperature, moisture, and pH

Creator:: Murphy, Bailey
Abstract:: Soil respiration has been identified as one of the largest natural sources of CO₂ to the global carbon cycle. Small alterations in the magnitude of soil respiration can have potentially large effects on concentrations of atmospheric CO₂ , making the rate at which respiration occurs of great scientific interest (Martin...

Linking dynamics of the near-surface flow to deeper boundary layer forcing in the nocturnal boundary layer

Creator:: Smoot, Alexander R.
Abstract:: Weak-wind flow in the nocturnal boundary is one of the most poorly understood problems in the field of meteorology. The understanding of weak-wind flows is essential for the improvement of regulatory dispersion models which are currently rendered invalid under weak-wind conditions and stable stratification. Recently there have been increased efforts...

Application of controlled thermal expansion in diffusion bonding for the high-volume microlamination of MECS devices

Creator:: Pluess, Christoph
Abstract:: Diffusion bonding has been widely used within microlamination architectures for the fabrication of Micro Energy and Chemical Systems (MECS). MECS are microsystems with the ability to process bulk amounts of fluid within highly-parallel microchannel arrays capable of accelerated heat and mass transfer. Thus far, diffusion bonding of the microchannel arrays...

Defining one’s role in citizen science: an exploration of the roles, perceptions and outcomes of participation in citizen science activities

Creator:: Clarke, Karl
Abstract:: Citizen science (formally public participation in science research) has emerged in recent years as an innovative and interactive tool for engaging many diverse groups in science and research. Defined as the collaboration of science professionals and the public in science research, citizen science has tremendously improved the reach of science....

Ammonia Volatilization from Nitrogen Fertilizers and Wastewater Reuse in the Columbia Basin

Creator:: Del Moro, Sarah K.
Abstract:: Ammonia (NH₃) volatilization and loss from nitrogen (N) fertilizer in agriculture negatively impacts crops, farm profitability, human health and surrounding ecosystems where it is deposited. A significant source of NH₃ volatilization occurs from surface application of urea on sandy soils with low pH buffering capacity such as those in the...

Interactive football playbook

Creator:: Neumann, Christoph
Abstract:: This thesis presents a domain specific visual language designed to allow coaches to create content that exhibits the complex 2D interactions observed in the game of American football. Coaches can visually program the content by using symbols and drawing primitives similar to those that they currently use to design static...

The phytosanitation of solid wood packaging materials using wood preservatives

Creator:: Schauwecker, Christoph F.
Abstract:: New species introductions have been associated with the movement of people for thousands of years. For instance, horses were introduced into North America by Spanish explorers, while pigs were introduced by the Polynesians into many Pacific islands long before the establishment of permanent European settlements. Both of these species introductions...

Development of an improved system for Oregon to accurately quantify dense-graded hot mix asphalt pavement density

Creator:: Darra, Suraj
Abstract:: The Oregon Department of Transportation (ODOT) standard specifications require a minimum density for the construction of dense-graded hot mix asphalt (HMA) pavements. Currently, the standard specifications call for density measurements for quality control (QC) and quality assurance (QA) testing to be made using nuclear density gauges that are calibrated using...
