The Changing Dynamics Of Coattails In Senate Elections, Sheila Dubron Lambert Jan 2005

The Changing Dynamics Of Coattails In Senate Elections, Sheila Dubron Lambert

UNLV Retrospective Theses & Dissertations

The prevailing theoretical approach in political science has been to analyze presidential coattails from a top down perspective focusing on the effect that presidential elections have on congressional outcomes. Presidential coattail research has been limited in scope to coattails as a one-way causation often examining variables in isolation, rarely accounting for the complex nature of elections and competing forces that influence elections across various levels of campaigns. This research seeks to present a more realistic view of campaign processes by assessing the spillover effects that campaign activity for one race may have on other races occurring simultaneously. Specifically, this thesis …

Improvements To Patient-Specific Skeletal Dosimetry, Jeffrey Scott Wyler Jan 2005

Improvements To Patient-Specific Skeletal Dosimetry, Jeffrey Scott Wyler

UNLV Retrospective Theses & Dissertations

Nuclear medicine encompasses numerous steps, with accuracy being a key component throughout. Exactitude in skeletal dosimetry is of importance due to the high radiosensitivity of the hematopoietic cells populating the marrow cavities within trabecular bone. In fact, active marrow is generally the dose limiting organ in both radioimmunotherapy and bone pain palliation; Current research involving improvements in skeletal dosimetry is being pursued through nuclear magnetic resonance- (NMR) and computed tomography- (CT) imaging. Images acquired from these imaging modalities are coupled to Monte Carlo transport models to calculate S values for radionuclides localized within the skeleton. This is accomplished by in-vivo …

Cracking Of Zircaloy-4 In Acidic Solution Under Controlled Potentials, Elumalai Govindaraj Jan 2005

Cracking Of Zircaloy-4 In Acidic Solution Under Controlled Potentials, Elumalai Govindaraj

UNLV Retrospective Theses & Dissertations

The susceptibility of Zircaloy-4 (Zr-4), a leading cladding material for nuclear fuels, to stress corrosion cracking (SCC) has been determined in an acidic solution at ambient and elevated temperatures by using constant-load and slow-strain-rate (SSR) testing techniques. Since the cracking susceptibility of Zr-4 may be influenced by electrochemical potential resulting from the repository environment, SCC testing has been performed under anodic and cathodic controlled potentials (Econt). While no failures were observed at constant load, the results of SSR testing exhibited enhanced ductility but reduced failure stress at elevated temperatures. The corrosion potential, determined by the cyclic potentiodynamic polarization technique, became …

A Modified Bootstrap Method For Handling Non Detects In Environmental Data, Michelle Melissa Guillaume

UNLV Retrospective Theses & Dissertations

Many samples taken for environmental purposes have concentrations that are measured below the detection limit. Below the detection limit does not mean that there is no concentration present; there may be a concentration present that cannot be accurately measured by the analytical instrument or cannot be determined with 95% confidence that the concentration is greater than zero (EPA, 1989). These concentrations are defined non-detects in the data. When the concentration of the contaminant of concern in a sample falls below the detection limit, it is standard laboratory procedure to represent these data as

The Role Of Applied Potentials On Cracking Of Zircaloy-2, Unnikrishnan Valliyil Jan 2005

The Role Of Applied Potentials On Cracking Of Zircaloy-2, Unnikrishnan Valliyil

UNLV Retrospective Theses & Dissertations

Consistent with the earlier observation, this investigation revealed that Zircaloy-2 (Zr-2) may exhibit enhanced ductility at elevated temperature when tested under the combined effect of applied stress and an acidic environment. Since the cracking susceptibility of Zr-2 may be influenced by applied potentials, SCC tests were performed in a similar environment under cathodic and anodic controlled potentials (Econt). While the effect of cathodic Econt was insignificant, Zr-2 exhibited enhanced cracking susceptibility when tested under an anodic Econt. The localized corrosion study using cyclic polarization indicates that the critical potentials became more active with increasing temperature. Secondary cracks were noted in …

The Punctuated Equilibrium Model Of Policy Evolution: An Explanation For United States Federal Fire Policy Change, Tricia Mynster

UNLV Retrospective Theses & Dissertations

The organizational structure of federal land management agencies is designed to function in a static state for long periods of time. Policies in these bureaucracies tend to follow a punctuated equilibrium pattern of evolution. These policies are accompanied by reinforcing institutional arrangements and networks that resist changes. In order for change to occur, a catalyst is needed to cause a drastic change in policy. Following this change, new institutional arrangements will be created to support the new policy. A catalyst is needed at the lower levels of the bureaucracy to follow a policy through to implementation. Using the National Park …

Points Of Contact: Nineteenth Century Visual Rhetoric Of The Underground Railroad, Theodore Ransaw

UNLV Retrospective Theses & Dissertations

Just as eighteenth century master seamstress Betsy Ross implemented more meanings and messages into the first American flag than what is obvious at first glance, so too did African American seamstresses weave messages into quilt patterns used on the Underground Railroad. Similar to the way themes of freedom and liberty in the Declaration of Independence were reinterpreted to include disenfranchised groups, Biblical themes such as heaven and the Promised Land were reinterpreted to include slaves. This study examines the visual rhetoric of nineteenth century textiles used by the Underground Railroad. From the evidence examined, I argue that the visual texts …
