Dosimetry Model for Alpha Emitters in a Radioactive Skin Patch for Treatment of Early-Stage Nonmelanoma Skin Cancers

Creator:: Squillante, Joyce
Abstract:: Nonmelanoma skin cancer (NMSC) is the most common malignancy in Caucasian populations. One existing treatment modality for NMSCs is external radiotherapy delivered to the skin cancer tumor by a beta-emitter-containing radioactive skin patch. Alpha emitters, with their higher linear energy transfer than beta particles and shorter range in tissue, make...

Development of a Fundamental Depth-Dependent Neutron Dosimetry Model

Creator:: Anspach, Logan J.
Abstract:: Current neutron dosimetry methods rely on the assumption that charged particle equilibrium (CPE) is established within the tissue medium. This maintains that the kinetic energy transferred to the medium (KERMA) is equivalent to absorbed dose. However, this assumption is only valid for large volumes such as the whole body. For...

Skin depth dose response of an ionization chamber and a thermo-luminescent dosimeter system using low energy X-rays

Creator:: Fowler, Adam (Adam James)
Abstract:: The use of Ionization Chambers and Thermo-luminescent dosimeters (TLD's) in the medical field has established a need to determine if the skin depth dose response is comparable between the two detectors. This research will determine if the dose response from an Ionization chamber is comparable to a Thermo-luminescent dosimeter system...

Nanoscale Instrumented Indentation Testing with the Current Capabilities of MOOSE and Marmot

Creator:: VandenBroeder, Gavin T.
Abstract:: Nanoscale Instrumented Indentation Testing (IIT) is a material characterization technique that is used to determine mechanical properties. The size effects present at this scale make it difficult to expand findings to a bulk scale. Modeling can be used to bridge this gap and better understand nanoscale IIT and the size...

Geoarchaeological research within five river miles of the Upper Klamath River Canyon : use of pedogenic properties to calculate alluvial terrace age

Creator:: Hescock, Sara
Abstract:: Soil is a valuable medium when investigating the past-- from understanding rates of development, landform evolution, to the construction of various predictive models. Landforms and sediments provide insight into depositional environments and soil morphology indicates pedogenic change within those landforms. The rate at which pedogenesis occurs has been quantitatively measured...

Caution! High Water: A Historical Archaeological Investigation of the Champoeg Townsite (ORMA26) after the 1861 Flood

Creator:: Hill, Cayla L.
Abstract:: The Champoeg townsite first developed due to its ideal settlement and trade location within the Willamette Valley, becoming the ‘legal birthplace of Oregon’ in 1843. However, by 1860 Champoeg’s significance had begun to decline, and in December of 1861 a devastating flood wiped out the townsite. Archaeological excavations took place...

Special Nuclear Material Classification and Mass Content Estimation Using Temporal Gamma-Ray Spectroscopy and Machine Learning Methods

Creator:: Curtis, Jessica R.
Abstract:: Improving the methods used for the detection and estimation of fissile material mass content is essential to nuclear security and safeguards to ensure special nuclear material (SNM) accountability, control, safety and security. With the continued expansion of the nuclear industry and the need for safe management of spent fuel, improving...

At River’s Edge: An Examination of Overseas Chinese Settlements in Northern Oregon during the Exclusion Act Era

Creator:: Maddoux, Maryanne F.
Abstract:: The written history of Oregon spanning the late 18th and early 19th centuries lacks evidence of the contributions made by the Overseas Chinese communities who existed in Oregon during this period. The purpose of this examination is to study the Overseas Chinese communities which resided in the cities of The...

Discrete Ordinates Radiation Transport using High-Order Finite Element Spatial Discretizations on Meshes with Curved Surfaces

Creator:: Woods, Douglas N.
Abstract:: We spatially discretize the Sn transport equation using the high-order (HO) discontinuous finite element method (DFEM) on HO meshes. Previous work provided a proof-of-concept for this spatial discretization method in X-Y geometry. Included in the present work, we derive a spatial discretization for the Sn transport equation in both X-Y...

Boredom, Buttons, and Booze: The Lifeways of an Enlisted Soldier Stationed at Fort Hoskins (35BE15), Oregon

Creator:: James, Shane P.
Abstract:: In 1976-77 and 2010, Oregon State University (OSU) excavated portions of the enlisted men’s barracks and privy at Fort Hoskins, a Civil War-era fort. In operation from 1856 to 1865, this fort served as part of a security network to protect and monitor the recently created Coast Indian Reservation. The...
