Assessment Of The Lactation Index For Managing White-Tailed Deer Populations, Kamen Lee Campbell Aug 2012

Assessment Of The Lactation Index For Managing White-Tailed Deer Populations, Kamen Lee Campbell

Theses and Dissertations

I analyzed precision and accuracy of lactation data to reflect actual fawn recruitment for various levels of fecundity, neonatal mortality, harvest intensity, and hunter selectivity. I evaluated and developed a correction equation to adjust for harvest date effects on lactation detectability. I compared metrics of site-specific fawn recruitment (e.g., lactation rates, hunter observation fawn-to-doe ratios, and post-season fawn-to-doe ratios) among themselves, and to site-specific indices of carnivore abundance, for 18 properties across Mississippi and Alabama. Accuracy of lactation rates are compromised due to variation at minimal harvest intensity and insensitivity to change in fetal rate or neonatal mortality. Lactation data …

Biofacies Analysis Of Late Mississippian Ostracodes And Their Use As Paleoenvironmental Indicators In The Bluefield Formation, Mercer County, West Virginia, Benjamin T. Stencil

Theses and Dissertations

The Bluefield Formation (Chesterian, Upper Mississippian) of the Appalachian Basin is a lithologically variable unit, composed of mudstones lithofacies with subordinate amounts of sandstone and limestone. By analyzing sedimentology and the prominence of ostracodes, an ostracode biofacies model was generated that provides a large-scale paleoenvironmental framework for the Bluefield Formation. Three ostracode assemblages were defined in an effort to identify environmental conditions during deposition of the Bluefield: Assemblage I - Polytylites Assemblage; Assemblage II - Sansabella Assemblage; and Assemblage III - Whipplella Assemblage. The assemblage distributions indicate that nearshore transitional marine environments were common and normal open marine conditions were …

Addressing Sample Bias And Representativeness At The Kinlock Site (22su526) A Freshwater Mussel Shell Ring In The Mississippi Delta, Joseph Alan Mitchell

Theses and Dissertations

Applied zooarchaeology provides baselines which can be used in modern conservation biology to better understand how faunal communities have changed over time. This goal can only be accomplished, however, by first accounting for the multiple biases present within the archaeological record, and how they may affect sample representativeness. Taxonomic analysis was conducted on freshwater mussel shell from the late prehistoric (ca. A.D. 700 - 1200) Kinlock site, Sunflower County, Mississippi. Species-area curves and biodiversity indices demonstrate that random sampling of surface clusters of shell, up to about 4,000 valves, provides an adequate picture of the overall surface assemblage. Comparison of …

Comparing Recreational Amenities Of University Towns And Non-University Towns, Timothy Allen Bisantz Aug 2012

Comparing Recreational Amenities Of University Towns And Non-University Towns, Timothy Allen Bisantz

Theses and Dissertations

Recreational amenities present great value for the community. Their existence provides an improved quality of life, offers a connection with the natural surroundings, and facilitates a healthy lifestyle. While communities continue to create and operate recreational facilities/areas, the presence of such facilities may have indirect effects on the general population. Specifically, this thesis will compare the presence of recreational amenities in metropolitan statistical areas that contain universities which are a part of the Association of American Universities (AAU) and metropolitan statistical areas with similar populations and geographic characteristics that don’t contain an AAU-member institution.

Computational Prediction Of Flow And Aerodynamic Characteristics For An Elliptic Airfoil At Low Reynolds Number, Varun Chitta Aug 2012

Computational Prediction Of Flow And Aerodynamic Characteristics For An Elliptic Airfoil At Low Reynolds Number, Varun Chitta

Theses and Dissertations

Lifting surfaces of unmanned aerial vehicles (UAV) are often operated in low Reynolds number (Re) ranges, wherein the transition of boundary layer from laminar-to-turbulent plays a more significant role than in high-Re aerodynamics applications. This poses a challenge for traditional computational fluid dynamics (CFD) simulations, since typical modeling approaches assume either fully laminar or fully turbulent flow. In particular, the boundary layer state must be accurately predicted to successfully determine the separation behavior which significantly influences the aerodynamic characteristics of the airfoil. Reynolds-averaged Navier-Stokes (RANS) based CFD simulations of an elliptic airfoil are performed for time-varying angles of attack, and …

Does Social Network Opinion Matter? How Implicit Theories And Social Network Opinions Can Influence Romantic Relationship Dynamics, Lauren Whitney Colvin Aug 2012

Does Social Network Opinion Matter? How Implicit Theories And Social Network Opinions Can Influence Romantic Relationship Dynamics, Lauren Whitney Colvin

Theses and Dissertations

The present study examined whether someone’s implicit theories of relationships (ITORs) has an effect on whose opinion and what type of opinion has more influence on their romantic relationship dynamics. Individuals high in destiny beliefs view relationships as either meant to be or not meant to be. Individuals high in growth beliefs think relationships take work to maintain and that problems can be overcome. Combined these form orientations- cultivation orientation where the individual is high growth/low destiny and evaluation orientation which is high destiny/low growth. I analyzed an archived dataset where participants completed Sinclair’s (2008) Social Network Opinion Scale, Lund’s …

Effects Of Sodium Methyldithiocarbamate-Induced Oxidative Stress On Nf-Kappa B Activation, Monica Cherie Gadson Aug 2012

Effects Of Sodium Methyldithiocarbamate-Induced Oxidative Stress On Nf-Kappa B Activation, Monica Cherie Gadson

Theses and Dissertations

Sodium methyldithiocarbamate (SMD) is commonly reported to cause health risks in humans. Previous reports indicate SMD causes oxidative stress, which can contribute to the activation of NF-êB and cause other characteristics of inflammatory responses to be altered. Almost all pro-inflammatory cytokines require NF-êB activation for full expression and development of an innate immune or inflammatory response. This study evaluated NF-êB activation, providing new information regarding reactive oxygen in macrophages from SMD-treated mice. Studies were conducted in which NF-êB reporter mice were treated with lipopolysaccharide (LPS), SMD, buthionine sulfoximine (BSO), and N-acetyl cysteine (NAC). BSO depletes glutathione (GSH) and increases oxidative …

Manganese Oxidation, Pseudomonas, And Potential Mercury Remediation, Kendra L. Wright Aug 2012

Manganese Oxidation, Pseudomonas, And Potential Mercury Remediation, Kendra L. Wright

Theses and Dissertations

East Fork Poplar Creek (EFPC) in Oak Ridge, TN was highly contaminated with elemental mercury in the 1950 and 1960. The area is still experiencing the effects of mercury contamination, and researchers are searching for ways to remediate the EFPC. One possible mechanism for bioremediation is the use of biogenic Mn oxides to remove heavy metals from water systems. Native Pseudomonas bacteria species were isolated from EFPC in order to examine biogenic Mn oxides production and bioremediation of Oak Ridge slurries. Pseudomonas isolates did produce Mn oxides which bound to mercury, and mercury bound to organic matter significantly decreased. However, …
