This study seeks to determine the feasibility of
utilizing one vaporizable copper compound - bis-[1-
(dimethylamino)-2-propanolato] copper(II) (Cu(DMAP)₂ as a
potential wood preservative. The synthesis of Cu(DMAP)₂
was conducted in accordance with a method developed by
Buhro and Dingman, Washington University, St. Louis,
Missouri. The yields of Cu(DMAP)₂ synthesis were...
In rats, sesame lignans increase plasma γ-tocopherol concentrations and inhibit γ-tocopherol degradation to its metabolite γ-carboxyethylhydroxychroman (γ-CEHC). To test if sesame lignan consumption inhibits γ- tocopherol metabolism in humans, muffins prepared with either corn oil (control) or sesame oil and an equimolar mixture of deuterium labeled d6-α- and d2-γ- tocopheryl...
The purpose of this research was to measure the copper-binding behavior of Dissolved Organic Matter (DOM) contained in Pulp and Paper (P&P) wastewater effluent and evaluate the Biotic Ligand Model’s (BLM) ability to quantify copper speciation in P&P influenced waters. A copper ion selective electrode was used to measure copper...
While the heartwood of many wood species exhibits excellent resistance to fungal and insect attack, this resistance is sometimes diminished in second-growth material of the same species. The reasons for the reduced durability are unclear, but they may reflect a combination of both higher proportions of sapwood as well as...

While the heartwood of many wood species exhibits excellent resistance
Treating durable, second-growth or plantation-grown material with supplemental chemicals could improve durability while enhancing the uniformity of the products. To test this hypothesis, the effect of two candidate biocide treatments on the durability of teak, redwood, and western redcedar was assessed in a ground proximity field test established in Hawaii....

Natural durability is generally lower in wood coming from second-growth
Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...
Malaria is the world’s most important parasitic infectious disease, and is a major cause of mortality and morbidity in many developing countries. In this dissertation I study the interaction of malaria and economic development at both the macro- and micro-economic levels.
In the first essay I examine the economic impact...

Malaria is the world’s most important parasitic infectious disease, and
Recent studies have found that equatorial Atlantic sea surface temperature (SST) variability may be influencing tropical Indian Ocean climate (Kucharski 2009, Wang 2009). Due to the economic and social impact of tropical cyclones, it is important to investigate how an Atlantic-Indian Ocean connection may be affecting tropical cyclone behavior in...
The elasticity of excess demand held by foreign buyers of United States agricultural products is critical for understanding the impacts of changes in farm policy and is a parameter that is much debated. The objective of my study is to estimate this parameter for major U.S. export crops, including wheat,...
