This study contributes a procedure, based on data analysis and geostatistical methods, to evaluate the distribution of chemical ratios and differentiate natural and anthropogenic contaminant sources of groundwater quality in the East Texas Basin. Four aquifers were studied, Sparta, Queen City, Carrizo and Wilcox. In this study, Carrizo- Wilcox is considered as one aquifer, and Sparta-Queen City as another. These aquifers were divided into depth categories, 0-150 feet for Sparta-Queen City and 300-600 feet and 600-900 feet for Carrizo-Wilcox in order to identify individual sources of contamination. Natural sources include aquifer mineral make up, salt domes and lignite beds. Major anthropogenic sources include lignite and salt dome mining and oil-gas production. Chemical ratios selected were Na/Cl, Ca/Cl, Mg/Cl, SO4/Cl, (Na+Cl)/TDS, SO4/Ca and (Ca+Mg)/(Na+K). Ratio distributions and their relationships were examined to evaluate physical-chemical processes occurring in the study area. Potential contaminant sources were used to divide the Basin into three areas: Area 1 to the east, Area 2 in the west and Area 3 in the center. Bivariate analysis was used to uncover differences between the areas. The waters in Area 1 are potentially impacted primarily from oil field waters. Sources present in Area 2 include lignite beds and oil …

ArcView and ArcInfo were used to identify and delineate areas contaminated by fluoride, sulfate, chloride, and nitrate in the Woodbine Aquifer. Water analysis data were obtained from the TWDB from the 1950s to 1990s covering 9 counties. 1990s land use data were obtained to determine the relationship with each contaminant. Spearman's rank correlation coefficients and Kruskal-Wallis tests were used to calculate relationships between variables. Land uses had little effect on distributions of contaminants. Sulfate and fluoride levels were most problematic in the aquifer. Depth and lithology controlled the distributions of each contaminant. Nitrate patterns were controlled mainly by land use rather than geology, but were below the maximum contaminant level. In general, contaminant concentrations have decreased since the 1950s.

The Texas Division of the United Daughters of the Confederacy (UDC) organized in 1896 primarily to care for aging veterans and their families. In addition to this original goal, members attempted to reform Texas society by replacing the practices and values of their male peers with morals and behavior that UDC members considered characteristic of the antebellum South, such as self-sacrifice and obedience. Over time, the organization also came to function as a transition vehicle in enlarging and empowering white Texas women's lives. As time passed and more veterans died, the organization turned to constructing monuments to recognize and promote the values they associated with the Old South. In addition to celebrating the veteran, the Daughters created a constant source of charity for wives and widows through a Confederate Woman's Home. As the years went by, the organization turned to educating white children in the “truth of southern history,” a duty they eagerly embraced. The Texas UDC proved effective in meeting its primary goal, caring for aging veterans and their wives. The members' secondary goal, being cultural shapers, ultimately proved elusivenot because the Daughters failed to stress the morals they associated with the Old South but because Texans never embraced …

Natural transformation is the process by which cells take up DNA from the surrounding medium under physiological conditions, altering the genotype in a heritable fashion. This occurs without chemical or physical treatment of the cells. Certain Acinetobacter strains exhibit a strong tendency to incorporate homologous DNA into their chromosomes by natural transformation. Transformation in Acinetobacter exhibits several unique properties that indicate this system's superiority as a model for transformation studies or studies which benefit from the use of transformation as an experimental method of gene manipulation. Pseudomonas putida is the natural host of TOL plasmids, ranging between 50 kbp and 300 kbp in size and encoding genes for the catabolism of toluene, meta-toluate, and xylene. These very large, single-copy plasmids are difficult to isolate, manipulate, or modify in vitro. In this study, the TOL plasmid pDKR1 was introduced into Acinetobacter calcoaceticus strains and genetically engineered utilizing natural transformation as part of the process. Following engineering by transformation, the recombinant DNA molecule was returned to the native genetic background of the original host P. putida strain. Specific parameters for the successful manipulation of large plasmids by natural transformation in Acinetobacter were identified and are outlined. The effects of growth phase, total …

The purpose of this thesis is to explore the creative process behind Southland Paper Mills, the South's first newsprint factory. The thesis describes the conditions leading to the need for southern newsprint. It then chronicles, through the use of company records, the difficult challenges southern newsprint pioneers faced. The thesis follows the company history from the gem of an idea during the mid 1930's through the first decade of the Southland's existence. The paper concludes with the formative years of the company in the 1940's.

For over one hundred years, the music-going public has reflected on the life and influence of America's “March King,” John Philip Sousa. His popularity as a bandleader was unprecedented, and his reputation as an entertainer captivated the imagination and intrigue of a nation. Sousa's fame was attained through the high standards showcased by his unparalleled concert organization, the Sousa Band. He is interminably linked to the march, and for his seventy-seven years he proved to be its prolific and outspoken champion. Sousa's songs, however, were among his favorite works, and their presence on concert programs reinforced a variety of programming that was the hallmark of his success. The Sousa Band served as a cultural and musical ambassador, and annual transcontinental tours brought music to people where they lived. Sousa's songs were highly anticipated concert features, and were presented by soprano soloists known as the “Ladies in White.” A chamber winds instrumentation, rather than employment of the full-forces of the Sousa Band, allowed for an appropriate musical balance between instruments and voice. The “Forgotten Songs of John Philip Sousa Project” involved the research, editing, and performance of songs housed in the Sousa Archives for Band Research at the University of Illinois. …
