Feeding, colonization and impact of the cinnabar moth, Tyria jacobaeae, on Senecio triangularis, a novel, native host plant

Creator:: Diehl, Jonathan W.
Abstract:: I conducted field and laboratory studies to determine the impact of the cinnabar moth, Tvria jacobaeae L., on the native perennial herb, Senecio triangularis Hook. The cinnabar moth was introduced into Oregon in 1960 to control the noxious weed Senecio jacobaea L. and is now well established on both the...

Walnut (Juglans regia) Phenols: I. Changes during ripening. II. Antagonisms for certain microorgainisms

Creator:: Diehl, John Harvey
Abstract:: Phenols from defatted walnuts were extracted with absolute methanol. The phenols were divided into four groups on the basis of molecular size. The antagonism of each group towards Escherichia coli, Staphylococcus aureus, and Aspergillus flavus was determined. Small polymers were the best antagonists of E_„ coli and Staph. aureus followed...

Moral dilemmas of bulimics and non-bulimics : a study of voice and self in eating disorders

Creator:: Wiggum, Candice Diehl
Abstract:: The central question of this study was to examine the moral orientation and the role of self in subject generated moral dilemmas for information on the developmental and cultural forces contributing to the etiology and maintenance of eating disorders in college women. The research was based on the theories of...

Politicized Collective Illness Identity and Boundary-Spanning in Western Montanan Community Health Workers: An Ethnographic Study

Creator:: McQuillan, Kindra
Abstract:: Background: Against global health disparities and a shortfall of medical personnel, community health workers (CHWs) promise a solution based in lived experience and connection to the health system. To address global and upstream health determinants, CHW programs engage the perspectives of both the workers they employ and the communities they...

From running birds to walking robots : optimization as a unifying framework for dynamic bipedal locomotion

Creator:: Hubicki, Christian M.
Abstract:: Bipedal locomotion is a complex phenomenon to understand and control, making it difficult for legged robots to achieve the speed, agility, efficiency, and robustness of their animal counterparts. This thesis argues for the use of numerical optimization to investigate and implement bipedal control as it applies to biology, dynamical models,...

Quantitative, multi-spectral, light-transmission imaging of colloid transport in porous media at the meso scale

Creator:: Kraft, Erika Lorna
Abstract:: Colloids, particles smaller than ten microns in diameter, are ubiquitous in the subsurface. Colloids have an effect on the transport of contaminants that bind to their surfaces, and can reduce the permeability of aquifer materials through deposition. Some microorganisms, including pathogens, are also transported in the subsurface as colloids. The...

Watershed modeling at Yucca Mountain, Nevada

Creator:: Britch, Michael J.
Abstract:: Studies are currently underway to determine the suitability of Yucca Mountain in Nevada as the nation's first high-level nuclear waste repository. Values of net infiltration are required to determine pre-waste emplacement groundwater travel times and the performance of the repository as a waste containment system. The objective of this study...

Comparing Delay and Reflected Inertia for an Actuated Spring Loaded Inverted Pendulum Model

Creator:: Reinschmidt, Kurt W.
Abstract:: Legged robots, while advancing quickly, have far to go before they can recover from major disturbances safely and consistently. Reflected inertia, which affects how quickly the actuators can physically respond to an environmental disturbance, and delay, which describes the time necessary for the controller to sense, re-plan, and respond to...

The Design Freedoms of a Novel Cable-Driven Manipulator

Creator:: Layng, Brian M.
Abstract:: Legged locomotion in robotics benefits from engineered hardware dynamics such as configuration-dependent, nonlinear transmissions and compliance. This thesis introduces a novel cable driven leg that allows the design of configuration-dependent transmission ratios while also permitting the addition of compliance in line with the cables to achieve compliant legged locomotion. The...

Template-based control of the bipedal robot ATRIAS

Creator:: Peekema, Andrew T.
Abstract:: This thesis details the derivation and application of template-based controls on a bipedal robot, as well as a description of the software framework that enabled experimentation. The software framework uses a combination of open-source tools including ROS, OROCOS, EtherCAT, and Xenomai to create a real-time environment for the controllers. The...
