An Ethologically Relevant Animal Model Of Post-Traumatic Stress Disorder: Physiological, Pharmacological And Behavioral Sequelae In Rats Exposed To Predator Stress And Social Instability, Phillip R. Zoladz

USF Tampa Graduate Theses and Dissertations

Post-traumatic stress disorder (PTSD) is a debilitating mental illness that results from exposure to intense, life-threatening trauma. Some of the symptoms of PTSD include intrusive flashback memories, persistent anxiety, hyperarousal and cognitive impairments. The finding of reduced basal glucocorticoid levels, as well as a greater suppression of glucocorticoid levels following dexamethasone administration, has also been commonly observed in people with PTSD. Our laboratory has developed an animal model of PTSD which utilizes chronic psychosocial stress, composed of unavoidable predator exposure and daily social instability, to produce changes in rat physiology and behavior that are comparable to the symptoms observed in …

Application Of Remote Sensing Methods To Assess The Spatial Extent Of The Seagrass Resource In St. Joseph Sound And Clearwater Harbor, Florida, U.S.A., Cynthia A. Meyer

USF Tampa Graduate Theses and Dissertations

In the event of a natural or anthropogenic disturbance, environmental resource managers require a reliable tool to quickly assess the spatial extent of potential damage to the seagrass resource. The temporal availability of the Landsat 5 Thematic Mapper (TM) imagery, 16-20 days, provides a suitable option to detect and assess damage to the seagrass resource. In this study, remote sensing Landsat 5 TM imagery is used to map the spatial extent of the seagrass resource. Various classification techniques are applied to delineate the seagrass beds in Clearwater Harbor and St. Joseph Sound, FL. This study aims to determine the most …

Aging With Identity: Integrating Culture Into Senior Housing, Christine Sanchez

USF Tampa Graduate Theses and Dissertations

There is an underlying hope that those whom are elderly can exist in a place of happiness, comfort, security and familiarity; and can do so by aging in a place which complies with an understanding of their needs as older adults. However, along with aging comes a negative association of dependence and deterioration. Therefore, it is intuitive to have a connection between both the aging process and the design process. Creating a product which brings a positive association with senior housing and aging in place is the underlying goal within the project and overall design.

With the increasing population of …

Paleoclimatic Reconstruction And Evaluation Of Sub-Centennial Climate Variability In The Late Holocene Using Records From Massive Corals (New Caledonia), Tree-Rings (New Mexico) And Speleothems (China), Kristine Lee Delong

USF Tampa Graduate Theses and Dissertations

This study focuses on how the construction of a paleoclimate time series influences the interpretation in the frequency domain. Three time series are examined: a New Caledonian coral (Amedee Island), a Chinese speleothem (Dongge Cave), and New Mexican trees (El Malpais).

This study presents a monthly resolved coral Sr/Ca time series from New Caledonia that reconstructs sea surface temperature (SST; 1648-1999). The chronology is based on density-band counting, cross-correlating Sr/Ca, and ²³°Th dating. The intracolony coral Sr/Ca variations are coherent on interannual to centennial time scales and are reproducible for >300 years. The SST reconstruction reveals estimated cooling trend (~0.4°C) …

Characterizing The In-Vitro Morphology And Growth Kinetics Of Intermediate Amyloid Aggregates, Shannon E. Hill

USF Tampa Graduate Theses and Dissertations

The mechanisms linking deposits of insoluble fibrils of amyloid proteins to the debilitating neuronal cell death characteristic of neurodegenerative diseases remain enigmatic. Recent findings suggest that transiently formed intermediate aggregates, and not the prominent neuronal plaques, represent the principal toxic agent. Evaluating the neurotoxicity of intermediate aggregates, however, requires unambiguous characterization of all aggregate structures present, their relative distributions, and how they evolve in time. Hen-egg white lysozyme represents an attractive model for studying intermediate aggregate formation since it is an extensively characterized globular protein, and its human variants can lead to systemic amyloidosis.

Combining in-situ dynamic light scattering (DLS) …

Endurance Materials For Hydrogen Sulfide Splitting In Electrolytic Cell, Jonathan Chinwendu Mbah

USF Tampa Graduate Theses and Dissertations

This study describes the development of a novel thin membrane exchange assembly (MEA) from a solid acid material, cesium hydrogen sulfate (CsHSO₄), and from a composite anode electrocatalyst for electrolytic splitting of (100 %) H₂S feed content gas operating at 135 kPa and 150 °C. A new class of anode electrocatalyst with the general composition, RuO₂/CoS₂, and an improved proton conductor, CsHSO₄, have shown great stability and desired properties at typical operating conditions. This configuration demonstrated stable electrochemical operation for 24 h with a (100 %) H₂S fuel …

Geocoronal Hydrogen Observations Spanning Three Solar Minima, S. M. Nossal, E. J. Mierkiewicz, F. L. Roesler, L. M. Haffner, R. J. Reynolds, R. C. Woodward

Publications

The 11-year solar cycle is a dominant source of natural variability in the upper atmosphere, and its effect on atomic hydrogen distributions and emissions must be understood to investigate possible signs of longer-term climatic trends in this region. We present midlatitude geocoronal hydrogen Balmer α observations from solar cycle 23 (1997–2006) and three solar minimum periods, 1985, 1997, and 2006. The 1997 through 2006 observations were taken with the Wisconsin H-αMapper Fabry-Perot (WHAM), a ground-based CCD-annular summing instrument that began observations at the Kitt Peak Observatory in Arizona in 1997. The 1985 observations were made with a similarly …
