Design and analysis of radiation shielding eyewear

Creator:: Spackman, David A.
Abstract:: The recent reductions to the international dose limit recommendations for the lens of the eye have renewed interest in radiation protection strategies in interventional fluoroscopy, where eye-lens radiation exposure occurs frequently. Radiationshielding eyewear can significantly reduce lens dose in these scenarios, but accurate protection factors are elusive because they depend...

Deep ultraviolet solid-state laser development

Creator:: Dutton, David A. (David Adam)
Abstract:: There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible. This thesis examines the possibility of using this crystal to generate...

Butterfly Puddling: An Alternative Cs-137 Pathway to the Pale Grass Blue Butterfly Following the Fukushima Nuclear Accident

Creator:: Hermann, David A.
Abstract:: Environmental modeling as a result of the Fukushima accident has been at the forefront for present day health physics. The accident released radionuclides in the environment and the fate and transport of these radionuclides are of interest when considering doses to non-human biota. The Pale Grass Blue Butterfly was studied...

Developing a multimedia tree identification CD-ROM

Creator:: Zahler, David A.
Abstract:: Providing students with the skills necessary to identify trees is an ongoing challenge at Oregon State University. Several colleges within the university offer courses that teach tree identification. In the College of Forestry alone, two courses are offered that emphasize identification of native and introduced trees. The content and format...

Examination of Immobilized TiO₂ Nanoparticle Photocatalytic Treatment of Stormwater by LilyPads

Creator:: Lopez, David A.
Abstract:: Stormwater runoff is a significant cause for impairment of many water bodies, a problem that will inevitably escalate due to increasing land-cover change associated with urbanization. The effect of stormwater runoff has spurred legislation and the subsequent development and adoption of Best Management Practices (BMPs) to treat stormwater. This work...

Blood-based gene expression as a biodosimetry model for neuroblastoma patients treated with ¹³¹I-mIBG

Creator:: Edmondson, David A.
Abstract:: Internal dosimetry is challenging and relies on estimates using MIRD or ICRP biokinetic models. To address this, we looked at gene expression analysis in whole blood from radiotherapy patients. Patients with relapsed or refractory neuroblastoma who received ¹³¹I-mIBG at UCSF were used to correlate internal ionizing radiation (IR) dose with...

Dislodgement and deformation of microbubbles in laminar channel flow

Creator:: Tence, David A.
Abstract:: In this thesis the critical parameters involved in the dislodgement and deformation of microbubbles in laminar channel flow, are determined and evaluated. Experimentally the effects of surface tension, viscosity, fluid flow rate, density, and bubble diameter on bubble dislodgement were evaluated. A theoretical scale analysis was performed which provided a...

Effects of acute stress and tagging on the swimming performance and physiology of Pacific lampreys (Lampetra tridentata)

Creator:: Close, David A.
Abstract:: Pacific lampreys (Lampetra tridentata) have declined in abundance in the Columbia River Basin. Although, the reasons for the decline are unclear, we suggest that development of hydroelectric dams and habitat alterations in tributaries as the main causes. The available knowledge of life history of Pacific lampreys and status from dam...

An application of photogrammetric techniques to the measurement of historic photographs

Creator:: Strausz, David A. Jr
Abstract:: The application of the collinearity solution by resection of the interior and exterior orientation parameters of historical photographs is investigated. The spatial coordinates of seven or more identifiable control points in the field of view of an historical photograph, combined with image coordinates of the control point images, allow solution...
