In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...
Little is known about the effects of arabinoxylans (AX) on noodle quality. The aim of this study was to observe interrelationships between wheat flour AX, SRC tests, and noodle quality attributes, and to investigate the use of SRCs to predict cookie diameter. Cookie diameter is the most common index of...
Utilization of solar energy or wind energy for electricity production is inherently challenging due to the diurnal and seasonal variations and normal intermittency. Effective, high efficiency storage methods need to be developed for further advancing renewable energy utilization. Endothermic chemical processing and thermochemical energy storage can be both employed as...
The use of an antibiotic as a growth promoter (AGP) began in the 1940’s with the discovery of growth responses from Streptomyces aureofaciens in the monogastric diet. However, resistance and residue problems have increased the negative consumer perception of growth promoting antibiotic use in animal diets. Although no direct link...
Bridge inspections are vital for monitoring the health and serviceability of transportation infrastructure throughout the world. However, inspections can be logistically-challenging, expensive, and dangerous. For example, inspections may require climbing, as well as the use of scaffolding, ladders, rescue boats, bucket trucks, and/or under-bridge inspection vehicles. Small, multirotor unmanned aircraft...
This dissertation focuses on a central question for six countries in Asia: what factors affect environmentalism? Numerous studies have proposed mixed theoretical explanations for the relationship between diverse values and beliefs regarding environmentalism. Although these diverse studies propose theories for the fast-growing and multifaceted environmentalism in Asia, here it is...
Thiamin and ascorbic acid content and retention were determined
in raw, blanched, pouched and canned green beans immediately
after processing and after storage for four months at room temperature
or at 37.5°C. Ascorbic acid was also determined in raw, pouched
and canned Royal Ann cherries immediately after processing and after...
In this thesis, I present the variational database management system, a formal framework and its implementation for representing variation in relational databases and managing variational information needs. A variational database is intended to support any kind of variation in a database. Specific kinds of variation in databases have already been...
