A quantitative comparison of cardiovascular imaging systems with respect to the resolution capabilities and the resulting skin entrance doses operating in both fluoroscopic and cine mode

Creator:

Helms, W. Scott

Abstract:

The increasing use of medical procedures using ionizing radiation has increased significantly in recent years. In 1987, the National Council on Radiation Protection Report 93 (NCRP) reported that the average exposure ionizing radiation was 53mRem/year (0.53mSv/year). In their most recent study on radiation exposures NCRP Report 160 in 2009, the...

Validation of radiographic automatic exposure control device testing in the era of filmless radiography : and new variables associated with testing

Creator:

Allman, Robert M.

Abstract:

The exposure needed for a clinically useful image requires much less precision when using digital radiography (DR) than when using screen/film (SF) radiography. The Automatic Exposure Control (AEC) device was developed for ensuring accurate and precise exposures with SF technology. This thesis evaluates the importance of the AEC device in...

Molybdenum-99 production in the Oregon State TRIGA reactor : analysis of the reactor design using a new LEU target as fuel

Creator:

Hummel, Andrew J.

Abstract:

The most widely used and versatile medical radioisotope today is technetium-99m. Roughly 30 million people depend on this radioisotope for diagnostic procedures each year, and this demand is expected to grow. Although there are numerous ways of procuring this isotope, the most common and most practical, for reasons to be...

Mechanics of three-dimensional microenvironments of cells

Creator:

Jones, Christopher

Abstract:

The structure and mechanics of tissues affect many important cellular functions such as migration, differentiation, and growth. Mechanical interactions between cells and the extracellular matrix (ECM), as well as ECM-mediated mechanical communication between cells, plays a part in coordinating collective cellular dy- namics during critical processes such as morphogenesis, tissue...

Efficiency of a direct contact condenser in the presence of the noncondensable gas air compared to a tube and shell condenser

Creator:

Lebsack, Jonathan M.

Abstract:

Steam distillation is the traditional method used for the extraction of peppermint oil. This process is able to remove approximately 20% of the oils from the leaves of the plant. It is a very costly and un-sustainable process due to the release of carbon emissions. Solvent free microwave extraction promises...

Non-Stoichiometry in Bismuth Perovskite Solid Solutions

Creator:

Prasertpalichat, Sasiporn

Abstract:

The role of A-site non-stoichiometry was investigated in lead-free piezoelectric ceramics based on compositions in the 1-x(Bi₀.₅Na₀.₅TiO₃)-xBaTiO₃ system near the morphotropic phase boundary where x = 0.055, 0.06 and 0.07. The samples were prepared by a conventional solid state mixed oxide route with the A- site stoichiometry modified to incorporate...

Evaluating the presence of radium-226 in soil surrounding a coal-fired power plant using the multi-agency radiation survey and site investigation manual (MARSSIM)

Creator:

Herring, Thomas A. (Thomas Andrew)

Abstract:

Coal-fired power plants constitute a significant source of energy production for the United States, and are projected to do so for decades to come. Most of the scrutiny coal-fired power plants receive is in the form of environmental concerns regarding green house gas emissions of carbon dioxide, sulfur dioxide, and...

Advancing the understanding of bulk metallic glasses as structural materials through exploration of mechanical properties

Creator:

Naleway, Steven E.

Abstract:

Bulk metallic glasses (BMGs) offer a great deal of potential through their near-theoretical strength, potentially high toughness and unique forming and molding traits. However, there are still a number of outstanding issues that bar their widespread use. This thesis describes the investigation of three research questions each designed to further...

Seismic performance of diagrid steel structures using single and double friction mass dampers

Creator:

Ramadhan, Garlan

Abstract:

The steel diagrid structural system is a recent load bearing and lateral resisting structural system for tall building structures that is relatively unexplored in the western United States. One possible reason for the little use of diagrid systems in earthquake prone regions is the lack of guidelines and application examples...

Group scheduling in electronics manufacturing with integration of internal and external setup times

Creator:

Yazdani Sabouni, Mohammad Taghi

Abstract:

This research considers a combinatorial optimization scheduling problem in the assembly of printed circuit boards (PCBs) in electronic manufacturing. For the first time in this research, the preparation process, which is typically called kitting operation, is paid attention to and is performed along with the assembly operation, described in this...
