Development of a Strain Gage Program for the Measurement of Strain on Prototypic, Plate-type, High Performance Research Reactor Fuels under Flow Testing

Creator:: Weiss, Aaron W.
Abstract:: A large, multi-year experimental program has been conducted to develop a strain gaging program for application to the flow testing of prototypic, plate-type fuel for high performance research reactors. This test program has resulted in the selection of appropriate strain gage construction, adhesives, and protective coatings to allow the acquisition...

Drone Strikes : The Moral, Political, and Legal Implications of the Changing Character of War

Creator:: Khalife, Ryan A.
Abstract:: Drone strikes have become a defining strategy in the US War on Terror. Since the first combat drone strike in 2001, the executive branch has intentionally increased the deployment of drones for counterterrorism operations throughout the Middle East and North Africa. This thesis explores the moral and legal justifications for...

A Study of Charging Behaviors in Organic Semiconductors using Optical Trapping

Creator:: Founds, Graham M.
Abstract:: We measure the charging and discharging of two organic materials, PCBM and ADT-TES-F. These materials are studied through the noncontact method of particle trapping known as Optical Tweezers, where an IR laser is used to constrain the motion of a coated or noncoated silica sphere while its positional data is...

Optical Tweezers-Based Probe of Charge Transfer in Organic Semiconductors at Microscopic Scales

Creator:: Busche, Jacob A.
Abstract:: A method for measuring the (dis)charging dynamics of organic semiconductors with single-electron resolution in multiple environments is developed using optical tweezers. A 1μm silica bead was coated with either a pristine organic semiconductor or an electron donor-acceptor blend, trapped using optical tweezers, and driven with an oscillating electrical driving force....

Potential effects of sea-level rise on plant productivity: species-specific responses in northeast Pacific tidal marshes

Creator:: Janousek, Christopher
Abstract:: Coastal wetland plants are adapted to varying degrees of inundation. However, functional relationships between inundation and productivity are poorly characterized for most species. Determining species-specific tolerances to inundation is necessary to evaluate sea-level rise (SLR) effects on future marsh plant community composition, quantify organic matter inputs to marsh accretion, and...

Creating a Predictive Model of Cinder Cone Evolution in Central Oregon

Creator:: Das-Toke, Shyam P.
Abstract:: Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. This is largely because cinder cones are produced by monogenetic eruptions. Characterizing large cinder cone fields in terms of age...

The Role of Facilitation for Maintaining Key Processes of Sagebrush-steppe Plant Populations in a Changing Climate

Creator:: Weisgerber, Elizabeth K.
Abstract:: Drought events have been shown to impact species distributions and are predicted to increase in frequency as the climate changes. As this occurs, ecologists predict species distributions will shift dependent upon species ability to track climate. These shifts in species distribution are expected to be particularly acute in arid and...

Exploring the Optical and Electronic Properties of Xylindein, a Fungus-Derived Pigment, as a Sustainable Organic Semiconductor

Creator:: Quinn, Alexander
Abstract:: Xylindein is an organic pigment derived from Chlorociboria aeruginascens and C. aeruginosa fungi that has shown promise as an organic semiconductor. Preliminary estimates of charge carrier mobilities (CCMs) on the order of 0.1 cm2/Vs were calculated from early tests on xylindein thin films, and photocurrents were also observed under laser...

Meeting the Night : The Science and Mystery of an Endangered Habitat

Creator:: Sisson, Jill
Abstract:: Night is an extraordinary resource. Unlike air, water, or soil, nighttime is a spatio-temporal phenomenon, which leads to many crucial roles. It provides refuge to wildlife species, triggers hormonal and behavioral responses among a wide variety of organisms, and serves as an essential migratory backdrop for species that navigate by...
