The properties of gold nanoparticles (GNP) holds promising potential for drug delivery, diagnostics, plasmonic photothermal therapy of diseases, electronics, catalysis, and photovoltaics (Liu et al., 2006; Huang et al., 2003; Thompson, 2007;...
Previous research has indicated the important role of visual information in the speech perception process. These studies have elucidated the areas of the brain involved in the processing of audiovisual stimuli. The McGurk effect, an audiovisual...
Speech intelligibility has been found to improve with prior exposure to a reverberant room environment. It is believed that perceptual mechanisms help maintain accurate speech perception under these adverse conditions. Potential factors underlying...
Short-term memory; Memory--Effect of sound on; Memory--Effect of noise on; Speech
The Irrelevant Speech Effect (ISE) is a phenomenon in which the presentation of
auditory materials (typically speech) impairs the serial recall of visually presented
materials, either digits or letters. Although this effect has been replicated in a...
The purpose of this research is to understand how the process parameters surrounding the Direct Metal Deposition (DMD) process affect the properties of the deposition. The powder used in this research is pre-alloyed titanium powder (Ti-6Al-4V),...
This work examines our perception of distance within "action space" (about 2m ~ 30m), an ability that is important for various actions. Two general problems are addressed: what information can be used to judge distance accurately and how...
Scheduling--Computer programs; Social work administration--Data processing; Public welfare administration--Data processing
The client flow of the Kentucky Cabinet for Health and Family Services is a complex process that deals with a high volume of clients on any given beginning half of the month. A simulation model of an average busy day in the system was built using...
When observers view a naturalistic (l/f) broadband image, the various spatial components present in the image stimulate many detecting-mechanisms that suppress each other. This suppression is anisotropic, being relatively greater for mechanisms...
Freshwater zooplankton; Global warming; Nitrogen--Environmental aspects
Aquatic ecosystems face major transformations as humans increasingly alter their environment by introducing exotic species and changing the temperature regime and nutrient availability of freshwater systems. The impacts of such alterations of...
Ethnocentrism; Mass media--Social aspects; Social problems--Press coverage; Mass media and public opinion; Mass media and race relations
This study revisits Kinder's and Kam's (2007; 2009) studies that provided
political scientists with a theoretical and operational definition of ethnocentrism-our
tendency to partition the world into in-groups and out-groups. They assert that...
Gold nanoparticles (AuNPs) have attracted enormous attention in the field of nanotechnology for applications such as, immunoassay, drug delivery, contrast enhancement and tumor therapy. The typical range of gold nanoparticles varies from 1– 150...
Supervisory control systems--Security measures; Computer security; Security systems
This thesis documents the successful development and testing of a more secure industrial control system field device architecture and software. The implementation of a secure field device has had limitations in the past due to a lack of secure...
Narrative causal understanding is related to a variety of school-related skills such as reading comprehension, and memory. Previous research shows a developmental trend in the ability to use and understand causal connections that begins at age 4...
Copper--Physiological effect; Copper in the body; Heart--Hypertrophy
Previous studies have shown that copper (Cu) supplementation at physiologically relevant levels reverses cardiac myocyte hypertrophy induced by phenylephrine (PE), and that this effect was VEGF-dependent. Yet, the amount of VEGF in the media was...
In order to study the movements of autonomous mobile robots, a tool is needed to quantify those movements. A testbed is an apparatus that provides a designated space for multiple mobile robots while tracking their position in real-time. That...
The current study investigated narrative comprehension ability in children from low-income families by examining the contributions of temperament, attention skills, and cognitive engagement. Research has identified narrative comprehension skills as...
Symmetric piezoresistive microcantilever beams have been demonstrated in previous research to be capable of sensing the presence of surrounding gas. This occurs as the damping effect of the gas changes the beam resonance behavior. Device...
Recently our lab has shown that with broadband stimuli (either visual noise or natural scenes), performance for detecting oriented content is worst at horizontal, best at the obliques, and intermediate at vertical orientations--an anisotropy...
This dissertation explores the physical and biological factors that control zooplankton population growth rates in the Ohio River (USA). I employed both observational studies and a mesocosm experiment to ascertain zooplankton population and...
