The new work I have developed while pursuing my Masters in Art at the University of Louisville is strongly based on the narrative. I have always used the imagery in my work as social commentary. The stories and images I develop are to be viewed as...
This dissertation describes (1) size-dependent electrochemical oxidation/stripping of gold and silver nanoparticles (NPs), (2) alloying of copper with gold nanoparticles at underpotential deposition potentials, (3) electrochemical characterization...
Colon (Anatomy)--Cancer--Genetic aspects; Cancer cells--Mathematical models
Research over the past twenty five years has led to the development of the hypothesis that colorectal cancer is caused by the accumulation of mutations in tumor suppressor genes and proto-oncogenes. The last ten years has also revealed that the...
Musical pitch--Data processing; Sound--Recording and reproducing--Digital techniques
Many mathematical formulas and algorithms exist to identify pitches formed by human voices, and this has continued to be popular in the fields of music and signal pro-cessing. Other systems and research perform real time pitch identification...
This dissertation describes new procedures for synthesizing and purifying Au and Au/Ag nanoplates directly on surfaces as well as controlled binding of proteins to their surface. It also describes fundamental changes in the optical properties of Au...
The thesis deals with the political career of John Marshall Harlan prior to his appointment in 1877 as an associate justice of the United States Supreme Court. Throughout the majority of those twenty-three active years in Kentucky politics, Harlan...

Acrolein--Toxicology; Stem cells--Effect of pollution on
Acrolein is a common pollutant present in ambient air, automobile exhaust, and tobacco smoke. Previous studies show that exposure to acrolein increases cardiovascular disease risk. To determine whether acrolein affect cardiovascular regeneration,...
Web search engines; Automatic abstracting; Graph theory--Data processing
After a user types in a search query on a major search engine, they are presented with a number of search results. Each search result is made up of a title, brief text summary and a URL. It is then the user's job to select documents for...
Microfabricated planar solar cells with an active solar collection area of 0.04cm2 were fabricated on n-type silicon wafers to test the viability of sputtered amorphous thin film photovoltaics for potential use in amorphous multijunction cells or...
Nanomaterials have many intriguing applications in biology and medicine. Unique properties such as enhanced electrical properties, increased chemical reactivity and resistance to degradation, novel optical properties and comparable size to that of...
Monoclonal antibodies directed toward tumor associated antigens are FDA approved anticancer reagents used commonly in the clinic. Administered antibodies initiate tumor cell death through several mechanisms. Improving immune mediated mechanisms,...
