A sense of place and time has been the unconscious focus of my adult life. While living in Hawaii I often searched for ancient rock carving sites. These art forms have the ability to convey the mystery, magic and history of previous times. I use human figures, beads and various textiles with similarities to these petroglyphs as a powerful metaphor for my search to find a place that is home

Mono-dispersed supported Ni catalysts were synthesized using the water-CTAB-hexanol reverse micellar system. The core of the reverse micelles contained an aqueous solution of NiCl2. Dynamic light scattering measurements showed that microemulsions having a water-to-surfactant molar ratio, Wo, of 10 lead to reverse micelles with lowest polydispersity, longest stability, and size range of interest. At an oil-to-aqueous phase ratio of 2, the diameter of the reverse micelles was found to increase with Wo in a linear fashion. At higher values of Wo (i.e. 25-30), the polydispersity was found to increase when lowering the amount of surfactant in the system. Ultimately, O/A = 2 and Wo = 10 were chosen as optimal conditions for microemulsion preparation. The aqueous NiCl2 concentration within the micelles was varied between 0.1 and 0.001 M. DLS results showed that although the average micelle diameter was between 70-83 nm throughout the range of metal salt concentrations, the crystallite size estimate based upon the reported micelle diameter and known aqueous NiCl2 concentration ranged between 2 to 7 nm. Therefore, the Ni crystallite size was varied by changing the aqueous NiCl2 concentration due to instability issues arising when changing the value of Wo. After deposition onto an alumina mesh support, the particles were dried, calcined, and reduced to produce Ni clusters. SEM and EDS analysis was used to confirm the presence of Ni compounds after the calcination stage. By the varying the aqueous NiCl2 concentration within the micelles, .0039, .0013, and .00039 wt. % Ni catalysts were produced and characterized using SEM. Particles in the size range of 10-14 nm were noticed for the .0039 wt. % Ni catalysts after reduction, 7-11 nm for .0013 wt. % Ni, and 5-9 nm for .00039 wt. % Ni. The lower-end of these particle size ranges was comparable to the crystallite size estimates. Ethane hydrogenolysis and ethylene hydrogenation reactions were conducted over the emulsion-prepared catalysts in order to determine particle size effects on catalytic activity. Results showed that the catalytic activity, defined in terms of per unit metal surface atom (or TON, turnover number), decreases with increasing particle size for the hydrogenolysis reaction. This trend may be due to an intrinsic size effect in which smaller particles exhibit the chemical or structural properties necessary for achieving a higher reaction rate. The results for ethylene hydrogenation showed that the reaction rate did not significantly change with crystallite size, confirming that the reaction is facile or structure-insensitive.

Cadmium (Cd) is a potentially toxic trace element. Two growth chamber studies were conducted to understand how: i) mono-ammonium phosphate affects durum wheat, flax or canola Cd uptake due to fertilizer induced changes in soil solution and plant; ii) preceding canola and barley affect the Cd uptake of subsequent durum wheat or flax. Durum wheat and flax shoot Cd concentrations were greater when grown on previous crop canola soil than when grown on previous crop barley soil regardless of what type of crop residue, if any, was added. The increase in Cd uptake for durum wheat and flax when on canola soil was probably due to increased availability of Cd in soil. Conversely, the application of mono-ammonium phosphate – reagent grade and the incorporation of preceding crop residue did not increase the crop Cd uptake of canola, durum wheat or flax and durum wheat or flax, respectively.

Martinsville, Virginia lost its textile industry to Mexico. High Point, North Carolina lost its furniture business to Asia. Pittsburgh lost Steel, Detroit lost auto-making, Mississippi lost cotton, and West Virginia lost coal. These once booming mono-industrial communities, competitive in a global economy, are all clawing their way out of a deep, dark unemployment whole. Each has a chapter in the story of urban decay and renewal with different endings. But the actions of their elected officials, before, during, and after their community's single industry downsizes or leaves, make all the difference. The following comparative policy paper examines the strategies of two local governments, those of Roanoke, Virginia, and Altoona, Pennsylvania, who attempted to mitigate the loss of Norfolk Southern Rail Car Repair Shops in their cities. I find quantitative and qualitative research, which suggests that Roanoke faired better after the loss of Norfolk Southern with regard to unemployment rates, median household income, high school and college graduation rates and poverty rates. I attempt a research design such that community leaders whose cities suffer similar economic blows can walk away with recommendations concerning their roles in recovery. Both cities relied greatly on the economic activity of Car Repair Shops. The staff at the Roanoke Car Shops, once comprised of more than a thousand men and women, has dwindled to a skeleton crew of about 15. The Hollidaysburg Car Shops also employed close to one thousand people, but too, has eroded to about a dozen. A history of each city and the evolution surrounding Norfolk Southern is included, along with an extensive examination into subsequent economic activity. / Master of Arts
