Characterization of the gut and skin microbiomes of wild-caught fishes from Lake Guntersville, Alabama
(2016-07-29)
In recent years, a paradigm shift has occurred in the area of organismal health. Where Koch and Hill’s fundamental postulates equating to “one microbe—one disease” were once regarded as the rule, research has now shifted ...
Mediterranean Diet Adherence in the Southeast United States: Validation of a Field-Based Survey Instrument and the Impact of Nutrition Knowledge
(2016-07-29)
The Mediterranean diet (MD) has been shown to reduce chronic disease risk, and nutrition knowledge has been shown to correlate with diet choices. However, Mediterranean diet adherence in the southeast United States is ...
Methane Exchanges between Terrestrial Ecosystems and the Atmosphere in Response to Multiple Environmental Changes - A Process-Based Modeling Study
(2016-07-29)
Methane (CH4), the most abundant non-carbon dioxide (CO2) greenhouse gas, has a relatively shorter lifetime (approx. 9 years) and higher global warming potential (approx. 28 times) than CO2 at a 100-year time horizon. The ...
Diversity and Conservation of the Southern Cavefish, Typhlichthys subterraneus
(2016-07-29)
The Southern Cavefish, Typhlichthys subterraneus, is one of the most fascinating stygobionts of the Amblyopsidae due to undescribed diversity within it. I investigated aspects of morphological and molecular diversity for ...
Advancing a better understanding of influences on relational health: A prevention science approach
(2016-07-28)
One of the strongest predictors of optimal health, well-being, and life satisfaction is having stable and supportive relationships (Pinker, 2014). Yet as evidenced by high rates of relationship dissolution, maintaining ...
Flow-Directed Assembly of Cellulose Nanocrystal Dispersions with Ordered Film Applications
(2016-07-28)
This dissertation presents the results of highly collaborative research on the fluid-phase assembly of cellulose nanocrystals (CNC) into ordered films. Due to their extraordinary properties, CNC are increasingly being ...
Phospho-silicate glass as gate dielectric in 4H-SiC metal-oxide-semiconductor devices
(2016-07-28)
Silicon carbide (SiC) based MOS devices are well suited to meet the need for energy efficient power electronics. For 4H-SiC MOSFET technology, one of the crucial challenges is to improve the quality of SiO2/SiC interface, ...
Examining Career Patterns of Football Bowl Subdivision Directors of Athletics
(2016-07-28)
The career path to become a collegiate athletics director is an area of interest to young professionals who seek this position. This study examined Football Bowl Subdivision Directors of Athletics within Division I of the ...
Simulations of Sawtoothing in the CTH Stellarator-Tokamak Hybrid
(2016-07-28)
Numerical extended MHD simulations are used to gain insight into the effect of three-dimensional shaping from the Compact Toroidal Hybrid (CTH) stellarator field on sawteeth. Numerical solutions having repeated sawtooth ...
Red or Blue: Does the choice of hue influence the way you learn the things you do? A mechanistic account of the effects of incidental choice on motor learning.
(2016-07-28)
The enhancement of motor learning is important for a myriad of activities. One way to enhance motor learning is to increase the autonomy of the learner. This can be done in several ways but typically centers around the ...
Characterization of High Speed and Arbitrary Headwall Injection Effects on the Trkalian Swirling Mean Flowfield in Rocket Motors
(2016-07-28)
In this work, the bulk gaseous motion inside cylindrical chambers driven by wall normal injection with and without reactive headwalls is explored. The base model is of the Trkalian type and is here extended to include ...
Effect of substratum topography on algal turf colonization and productivity under different nutrient conditions
(2016-07-28)
Algae can act as a promising source for biofuel production, pollution recovery from natural waters and nutrient recovery from wastewaters. Typical algae cultivation involves algae in the suspended form, and separation ...
Protective Effects of Positive Emotions
(2016-07-27)
This dissertation investigates the protective effects of positive emotions in cognitive and physiological realms. Previous research indicates that positive emotions lead to broader thinking compared to negative emotions ...
Neuroprotective effects of carnitinoid antioxidants in rodent models of mitochondrial dysfunction
(2016-07-27)
The pathological effects of mitochondrial dysfunction result from both oxidative damage and bioenergetic deficiency, and are more severe in cells and tissues with high metabolic energy demands such as neurons, skeletal ...
Building Nonalignment: Technological Interchange and India’s Third Five-Year Plan (1961-1966)
(2016-07-27)
The role of ideology in the modernization of India has been closely studied. Less well understood is the role that technological knowledge and artifacts played. This dissertation studies the role of technology in the Indian ...
Design and Simulation of Cryogenic Test Circuits
(2016-07-27)
New technologies are being introduced in anticipation of the end of Moore’s Law, such as quantum computing, in hopes that the speed gains from the different topologies will offset the increase in size of the devices. Fast ...
