Effects Of Subchronic Dietary Lead Exposure On Dmtp And Dnmtp Performance In Fisher 344 Rats, Joshua D. Vardigan

Masters Theses

Recent attention has focused on the possibility that even low-level Pb exposure can produce subtle neurological impairments in the absence of overt signs of toxicity. Previous behavioral assessments of learning and memory using DMTS procedures have documented learning impairments in monkeys exposed to Pb during early postnatal development, and although a variety of operant behavioral assays have documented detrimental effects of dietary Pb treatment in rats, the DMTS procedure has not been examined in rats following short-term low levels of Pb through dietary exposure. Thus, the objective of this study was to measure the degree of cognitive impairment produced by …

Using Non-Fiction Conventions To Improve Expository Reading In 6* Grade History, Annie Whitlock

Masters Theses

Students often have very little experience with textbooks before they reach the middle and upper grades. Teachers of content areas in these grades also have very little resources available to help these students. In this study, a curriculum was developed to teach specific non-fiction conventions to 6th grade students in a history classroom. The purpose of the study was to test the hypothesis that this developed curriculum would positively impact these students’ abilities to use non-fiction conventions while reading their textbook. The results of the study revealed that after being taught the developed curriculum, the students made improvements and showed …

Correlating Grain Boundary Microstructure And Ductility Loss On Aging In Haynes® 25, Darryl Britt Glanton

Masters Theses

Haynes® 25 is a cobalt-base superalloy known for its excellent high temperature strength and corrosion resistance. However, this alloy undergoes severe embrittlement on aging at elevated temperatures. Historical research associated this ductility loss with the formation of a Co₂W Laves phase, but more recent studies have challenged the existence of this phase after prolonged aging at temperatures above 600°C. In this study, scanning and transmission electron microscopy were used to characterize the chemistry and location of precipitates in the alloy after aging at temperatures of 675 and 850°C for times up to 12,000 hours. These data were compared …

Estimation Of Surface Temperature And Heat Flux Using Embedded Thermocouples, Jeffrey Daniel King

Masters Theses

This thesis investigates several new methods for estimating surface temperature and heat flux based on thermocouples embedded within the interior of a test article. The test apparatus was a Mach 2 axisymmetric rocket nozzle with probes embedded at depths of 1/8” and 1/4” from the inner surface of the nozzle at the throat and exit locations. Three methods for numerically estimating temperature and heat flux at the surface of the nozzle were considered: a one-thermocouple slab-coordinate method, a two-thermocouple slabcoordinate method, and a finite-element analysis (FEA) based on a one-dimensional cylindrical coordinate method. Comparisons between the methods, as well as …

Characterization Of The Temperature Dependence Of Optical Components In A Cryo-Vacuum Chamber Used For Space Sensor Testing, Jesse M. Labello

Masters Theses

The space sensor cryo-vacuum chambers at Arnold Air Force Base are world class sensor characterization and calibration facilities. The chambers provide a simulated deep space background and accurate infrared projections. Several large optical systems are used within the chambers to accomplish this. Calibration of the chambers requires the use of a database of the measured optical properties of these components to simulate the output. However, as the information in the database is room temperature information and the chambers run near 20K, some discrepancies exist between the actual output and the model output. The purpose of this work is to translate …

Freedom To Work, Nothing More Nor Less: The Freedmen’S Bureau, White Planters, And Black Contract Laborers In Postwar Tennessee, 1865-1868, David Stanley Leventhal

Masters Theses

This thesis explores the black labor situation in postwar Tennessee from 1865 to 1868. Using a wide array of primary sources from Tennessee, the research unveils an inherent bias in the Freedmen’s Bureau’s forced contract system of labor. My conclusions highlight the collusion and complacency of bureau officials and planters who confined freedpeople to agricultural labor during the initial years of African-American freedom. Whites—Northern and Southern—worked cohesively toward common goals of agricultural prosperity, law and order, and white supremacy.

The bureau’s contract system was devised as an emergency measure to put idle blacks back in their “appropriate” positions as agricultural …

Cfd Characterization Of Automotive Inflator-Generated Gas Distribution Process, Scott Alan Lusted

Masters Theses

This thesis outlines the application of Computational Fluid Dynamics to the characterization of the gas distribution process inherent in automotive gas generators. The gas distribution process is important to understand as it greatly influences the overall performance of the device and its competitiveness in the marketplace. Presently, there is limited analysis that has been conducted on the gas generators. The current method involves conducting experiments using prototype hardware and high speed video to capture the flow field. This approach has proven to be useful; however, it lacks the ability to thoroughly study the fluid dynamics. Furthermore, the analysis has to …

Site Formation Processes In An Upland Paleoindian Site: The 2005 – 2007 Topper Firebreak Excavations, Darcy Shane Miller

Masters Theses

In the Southeastern United States, archaeological sites dating to the Paleoindian period are elusive. This study examined whether the Topper Site (38AL23) in Allendale County, South Carolina has buried, relatively undisturbed Paleoindian deposit using a sample excavation block removed during the 2005-2007 field seasons. Artifact horizons were defined by plotting the density of each bulk provenience against a vertical profile. The vertical displacement of refitted artifacts and the position of diagnostic artifacts were used to test the integrity of these horizons. The results indicate a discrete deposit associated with diagnostic Clovis artifacts. Subsequent analyses tested for horizontal post-depositional movement, and …

From Gay Street To Turkey Creek: Knoxville’S Urban And Suburban Growth Machines, Katherine Leigh Morris

Masters Theses

Using growth machine theory, this study examines the newly built "lifestyle center" of the suburban Turkey Creek development and the redevelopment of the Gay Street corridor in downtown Knoxville, TN. Growth machine theory is one of sociology's predominant theories used to understand development and growth projects in metropolitan areas, and although not specifically defined in current literature, I suggest there are many differences in suburban and urban growth machines. This study examines the local dependency and organization of pro-growth coalitions; the tactics, ideology, and culture used to promote development projects; and community reactions. Upon completion of this project, I found …

The key features …

A Generalized Hamiltonian-Based Algorithm For Rigorous Nonequilibrium Molecular Dynamics Simulation In The Nvt Ensemble, Joseph Gerald Leo Rajkumar

Masters Theses

Using a recently developed, methodical, Hamiltonian-based procedure, we derive rigorous algorithms for nonequilibrium molecular dynamic (NEMD) simulation in the NVE and NVT ensembles. We demonstrate that the equivalence of the kinetic temperature and configurational temperatures that exists at equilibrium is maintained in nonequilibrium states, given the proper nonequilibrium expression (in the microcanonical ensemble). Specifically, we apply the procedure to the p-SLLOD algorithm, which allows for rigorous NEMD simulation in the presence of an arbitrary, externally imposed flow field. The resulting algorithms are general in that they apply in the presence or absence of external fields in addition to the imposed …

Rivers, Roads, And Rails: The Influence Of Transportation Needs And Internal Improvements On Cherokee Treaties And Removal From 1779 To 1838, Vicki Bell Rozema

Masters Theses

This study examines the importance of transportation routes and internal improvements as factors in treaty negotiations and the removal of the Cherokees. Covering a period from approximately 1779 to 1838, the date of forced Cherokee removal from east of the Mississippi, it argues that the Cherokees opposed the construction of military roads and turnpikes and interfered with travel through Cherokee country. Safe passage clauses in Cherokee treaties, issues dealing with passports through Cherokee country, and disputes over ferries and taverns on transportation routes are reviewed. The plans of Southern leaders such as John C. Calhoun and Wilson Lumpkin to build …

Henry Morgenthau: The Evolution Of An American Activist, Maggie Laurel Yancey

Masters Theses

Treasury Secretary Henry Morgenthau, Jr. was a central figure in the FDR administration in more than just fiscal matters. Morgenthau also worked from the 1930’s onward in several arenas to aid the Jewish victims of the Nazi Holocaust. My research updates and revises the existing historiography by revealing this activism was the logical culmination of years of interest in the fates of Jewish refugees. Furthermore, this activism was affected by several factors beyond Morgenthau’s own control. The administrative style of President Franklin Delano Roosevelt, relationships between Morgenthau and other members of the cabinet, and influential undercurrents within the cabinet all …

Evaluation Of Head Linear And Rotational Acceleration Response To Various Linear-Induced Impact Scenarios, Robert Paul Roy

Masters Theses

Incidents resulting in head injury generally involve components of both linear and rotational motion. The protection of the head from injury most often comes from the use of some form of helmet. Helmets currently are designed only to protect the head from linear accelerations. Recent research involving the analysis of concussion in professional football suggested that linear accelerations are more consistent in the prediction of concussion, with the resultant rotational accelerations correlating to the peak linear accelerations of the impact.

This research proposes to determine if the situation of the head impact has an effect on the correlation of the …

Depressive Symptoms In An Urban Kurdish Refugee And Immigrant Population: An Exploratory Study, Natalie Kay Worley

Masters Theses

The purpose of this study was to explore the prevalence of depressive symptoms among the elderly Kurdish immigrant and refugee population living in the greater Nashville, Tennessee area. Nashville has the largest population of Kurds living outside of Kurdistan (Metropolitan Government of Nashville and Davidson County, 2004), but as is the case for many immigrant and refugee groups, little empirical research exists to aid social service practitioners in addressing the unique needs of this population (Williams & Westermeyer, n.d.). The investigator draws on the limited research about mental health in other immigrant and refugee populations as a basis for the …

How Relational Views Influence Adolescents’ Subjective Understanding Of Romantic Relationship Interactions, Justin Dean Smith

Masters Theses

The purpose of the current study is to examine the influence of relational views on adolescents' subjective understanding of interactions in the context of their romantic relationships. Relational view is an attachment system construct comprised of three specific measures of attachment: attachment style, rejection sensitivity and self-silencing. To examine the influence of relational views on individual's subjective understanding, we are employing an innovative multimodal methodology: The video-recall system (Welsh & dickson, 2005). This system assesses adolescent participants' subjective understanding of their feelings and behaviors during a video-taped interaction with their romantic partner as well as trained observers' interpretations of the …

Sexual Dimorphism In The Vertebral Column, Amanda Suzanne Allbright

Masters Theses

Determining sex from skeletal remains is important in forensic and archaeological settings. Though using the pelvis to determine sex is ideal, often remains are fragmentary or incomplete, requiring sex to be estimated from other skeletal elements. Many individual bones have been studied to evaluate sexual dimorphism and the extent to which they can be used to determine sex of an unknown individual. However, sexual dimorphism in the vertebral column has only been examined to a limited extent.

The purpose of this study is to examine the extent of sexual dimorphism throughout the entire vertebral column and, if present, to establish …

Investigation Of The Sidewall Boundary Layers In The Bidirectional Vortex Liquid Rocket Engine, Joshua W. Batterson

Masters Theses

To complement previous studies on the bidirectional vortex, we attempt to characterize viscous effects in both the axial and radial directions along the sidewall with standard asymptotic techniques. The actual boundary layer present in the chamber will be a composite of both axial and tangential shearing layers. Since the tangential velocity is completely dominant, we expect the defining characteristics of the composite boundary layer to be congruent with the tangential layer in both thickness and axial invariance. The analytic analysis is outlined first by, the formulation of the boundary layer equations via Prandtl’s method. Next, asymptotic techniques are applied to …

Music Therapy With High-Risk Youth: An Exploration Of Current Practice, Beth A. Clark

High-risk youth were defined as those likely to experience a decline in global level of functioning due to one or more issues related to mental health, substance misuse, or other social, economic, or cultural disadvantages, including correctional system involvement, street-involvement, or unstable home environment. An online survey of credentialed music therapists was conducted to explore the areas of demographics, clinical practice and information-seeking. Music therapists working with high-risk youth were asked to identify the most …

Moment Of Encounter: A Critical Exploration Of Parent-School Communication, Gary Samuel Marx

Masters Theses

Relationships among parents and schools are situated in a complex hegemony. Communication is central to the identification and construction of power in schools. Schools employ a model of communication that locates power predominately with their representatives and values parents for conformity to organizational expectations. Shared power relationships challenge actors to encounter one another and co-contribute to the development of children. The goal of this study is to uncover various meanings and understandings from what parents recall from Moments of Encounter with school personnel. Such an examination is designed to reveal power at the microlevel, in the encounter itself, as well …

Effects On Level Flight Performance Of The Optimized Wind Deflector Modification For The Md-500 Helicopter, Adam Joseph Cowan

Masters Theses

This thesis investigates the effects of personnel wind deflector devices on the level flight performance of an MD-500D helicopter configured with external passenger provisions. Numerous helicopter organizations operate with external passenger configurations. These configurations result in personnel exposure to high winds and an increase in parasite drag. Level flight performance is degraded by the increase in parasite drag caused by the external passengers. Wind deflectors were mounted on the forward portion of the fuselage to protect external passengers from the effects of wind exposure (high wind loads and wind chill factor) by deflecting the wind away from the fuselage. The …
