Characterization And Reaction Of An Analog Of The Anticancer Drug Oxaliplatin, Jonathan D. Hendrie

Mahurin Honors College Capstone Experience/Thesis Projects

Oxaliplatin is an anticancer drug that reacts with DNA, RNA, and proteins both in vitro and in vivo. Our research focuses on synthesizing analogs of oxaliplatin and understanding how bulky ligand groups affect reaction with amino acids. (R,R)-N,N’-dimethyl-1,2-diaminocyclohexane platinum(II) oxalate or Pt(Me2dach)(ox) varies from oxaliplatin or Pt(dach)(ox) in that it has one methyl group attached to each platinum coordinated nitrogen. Nuclear Magnetic Resonance (NMR) spectroscopy has shown that the reactions of N-Acetylmethionine (N-AcMet) with Pt(Me2dach)(ox) and Pt(dach)(ox) proceed at similar rates suggesting that the methyl groups of Pt(Me2dach)(ox) have little effect on the initial reaction. Whereas the reaction of Pt(dach)(ox) …

Improving The Energy Efficiency Of Dehumidification Technology At A Large Facility In Florida, Brandon Willson Hoilett

Masters Theses, 2010-2019

This thesis examines energy use and management of twenty heat pipes used in dehumidification systems at a large (10,000+ acre) facility in Florida. Eleven of the twenty heat pipes use electric strip heaters that, when activated, consume 693.8 kW of electrical power from the grid. Solar photovoltaics, specifically a silicon monocrystalline cell with 22.5% efficiency, were considered as a means to provide an alternative energy source and opportunity for cost savings for 11 of the heat pipes (Sunpower, 2011). The remaining nine heat pipes use hot water heaters for which alternative energy sources were not considered. Data gathered and analyzed …

Potential Energy Savings When Using Saline Water For Cooling Chillers In Malta, Mireille Micallef

Masters Theses, 2010-2019

Several cooling systems found in facilities on the coast of St. Julian’s were found to be making use of chillers whose condensers are cooled with saline water as opposed to air. The former practice is advantageous since it results in better chiller performance which can be explained through thermodynamic principles. The principle of operation of water cooled chillers is to reject heat from the condenser to saline groundwater obtained from boreholes through a heat exchanger. The higher temperature saline ground water is then rejected to the sea. Chillers cooled with saline groundwater are subject to the Borehole Drilling and Excavation …

Meta-Heuristic Optimization Of Antennas For Biomedical Applications, Aaron Zachary Hood

Theses and Dissertations

Given the proper conditions, antennas applied in medicine can offer improved quality of life to patients. However the human body proves hostile to typical, analytical antenna design techniques as it is composed entirely of frequency- and temperature-dependent lossy media. By combining optimization techniques with numerical methods, many of these challenges may be overcome. Particle swarm optimization (PSO) models the solution process after the natural movement of groups such as swarms of bees as they search for food sources. This meta-heuristic procedure has proven adept at overcoming many challenging problems in the electromagnetics literature. Therefore, this dissertation explores PSO and some …
