The objectives of this research are to monitor tannin and anthocyanin changes during berry development and over several growing seasons to understand how the vintage effects wine composition. Specifically, the objectives of this research project are :
· Determine the effect of berry development on the composition of phenolics (tannins...
In most environments, ammonia (NH₃) is oxidized to nitrate (NO₃⁻) via the intermediate nitrite (NO₂⁻). This is a microbe-driven process involving phylogenetically distinct types of microorganisms, namely, ammonia-oxidizing bacteria (AOB) and Thaumarchaea (AOA), and nitrite-oxidizing bacteria (NOB). Nitrosomonas europaea and Nitrobacter winogradskyi are the best studied AOB and NOB, respectively,...
Color stability and mouth feel quality are two of the most important aspects of red wine quality. Anthocyanins and proanthocyanidins are responsible for these attributes and it has been shown that weather conditions during the growing season and grape maturity can effect these components in wine. However, investigations into proanthocyanidin...
Digital-to-analog converters (DACs) suffer from static and dynamic nonlinearity problems, which degrade their accuracy and performance. Mismatch errors in the analog components restrict the maximum achievable linearity.
This thesis presents various techniques for correcting these errors. It describes a correction process for the nonlinear behavior of DACs, on three different...
In this thesis, I examine Johan Galtung’s theory of violence and discuss how his concepts of cultural and structural violence helps explain the problem of direct violence among Mexican American youth. I argue that cultural violence, mainly dominant narratives of colonialism and masculinity, cause some Mexican American youth to act...
Latinos are the largest and most rapidly growing ethnic minority in the United States, and they have the highest dropout rates of any major ethnic group in the country (U.S. Department of Labor, 2003). Latinos' educational attainment is consistently lower than that of other students (Gandara, 2008). The majority of...
The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

Three genetically different dwarf cultivars of spring wheat were
evaluated as potential sources of short stature to use in a wheat improvement
program. The study involved a five parent diallel cross
which included a semidwarf, a standard height and three dwarf cultivars.
The genetic sources of dwarfism included a Norma...
