I. Lithium alkyl and aryl monosubstituted cyclooctatetraenide
dianions (Li₂ C₈H₇-R; R = methyl, n- butyl, sec- butyl, tert- butyl,
phenyl and benzyl) were synthesized by the reaction of the appropriate
organolithium reagent with cyclooctatetraene in diethyl ether or
tetrahydrofuran. The reaction occurred cleanly and with good yield
of lithium monosubstituted...
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...

Diatoms are a ubiquitous group of plankton responsible for 20-40% of oceanic
primary production, and a higher fraction of organic matter export to the ocean
interior. Diatoms actively transport dissolved inorganic silicon into their cells, and
through the process of silicification (i.e. biogenic silica production) they build tough
and intricate...
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...
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....

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...
