Salt Lick Prayer is a collection of poems divided into three parts. The first section includes poems that address the author's childhood years, and focus on themes of family, nature, and religion. The second section focuses on poems that explore the life of the author's great, great grandfather, and the third section deals with the author's great grandmother and grandparents.

The Palladium(II)-catalyzed homogeneous oxidation of 1-hexene in methanolic medium has been studied, copper(II) chloride being used as cocatalyst. Aspects of the kinetics, mechanism and product composition were investigated in several series of oxidations involving variation of hexene concentration, oxygen partial pressure, Cu(II): Pd(II) ratio and concentration and temperature. The progress of the reaction was studied in the course of periodic sampling runs. Reaction products were identified by gas chromatography, and verified by means of GC/mass spectrometry. The expected product of 1-hexene oxidation was 2-hexeanone: however, 3-hexanone occurs as a major coproduct, arising from concurrent Pd(II)-catalyzed isomerization of 1-hexene to 2-hexene. Isomerization is inhibited by excess copper(II) chloride. The overall oxidation is generally consistent with P.M. Henry’s mechanism for Pd(II)-catalyzed alkene oxidation, the rate-limiting step being the π-to σ-rearrangement of the Pd(hexane) complex. The corresponding ketals (2,2-dimethoxyhexane and 3,3-dimethoxyhexane) were also found. Free hexanal was not detected in any oxidation product mixtures; when produced it was found as the dimethyl acetal. Chlorination products were not observed. A surprisingly sharp rate maximum was observed when copper(II) chloride concentration was varied. Two kinetic regions were found to occur in virtually all oxidations. An explanation is proposed for this behavior.

Karstic cave systems are intricately related to surficial processes and the study of cave sediments is a growing field of research. Sediment deposits in caves are protected from surficial weathering processes, and are therefore often preserved. Cave sediments have applications in studies for paleoclimatic reconstruction, contaminant transport, and paleoflood and stream incision rates, making them valuable contributors to other areas of geoscience. Hidden River Cave is an active, multi-level cave system in the town of Horse Cave, Kentucky with over 33 km of mapped passages. A history of anthropogenic impacts on the cave system include uses for hydroelectric power generation, a water source, and a show cave until it closed in 1943 due to severe contamination from domestic and industrial waste. This study reports on the analysis of sediment cores collected from the cave system which show distinct concentrations of metals within the sediment from chrome plating plant effluent. Relative concentrations of metals in the core record were obtained using an ITRAX core scanner, and were observed to decrease moving downstream from the chrome plating plant contamination source. Sediment core analysis allows depositional patterns in the cave system to be observed and related to historic surficial processes. The chronology of sedimentation events was determined using Pb-210 analysis of core sediment and indicates a strong connection between historical contaminating events in the town of Horse Cave and cave sediment deposition. Sediment core analysis has thus allowed depositional patterns in the cave system to be determined and related to historic surficial processes. These findings can be applied to enhance understanding of the combined effects of landscape evolution and anthropogenic impacts which may be used to inform decision making processes for communities overlying both Hidden River Cave and other karstic cave systems. / Thesis / Master of Science (MSc)

Biostimulants (BIOS) are non-mineral substances that, when exogenously applied in very small quantities, stimulate the metabolic activity of plants. Past research with biostimulants has not included differing levels of nitrogen fertility or shade as variables. The research presented was designed to explore some interactions between biostimulants and nitrogen fertility on turfgrass grown under several light conditions. / Master of Science
