The purpose of the study was to write a history of the professional career of D. O. Wiley as a music educator from 1921 to 1963. To give focus to the career of Wiley, answers were sought to three questions, stated as sub-problems: (1) What were the important events and influences in the professional career of D. O. Wiley as a college/University band director? (2) What impact did Wiley have on the development of Texas public school bands that earned him the title "Father of Texas Bands?" and (3) What role did Wiley play in the development of the Texas Music Educators Association and other professional music organizations.

The specific aim of this study is to show the significance of the natural resources of Texas and their potential possibilities as an adequate source of income for the State. Linked in with this discussion and underlying it is the thesis that adequate taxation of the natural resources will not only provide sufficient income for the State's needs but also conserve and utilize these resources.

The purpose of the study was to examine the relationship between the professional activities of Col. Earl D. Irons and the overall development of bands in the Southwest. The need for the study was determined after researching the related literature, which revealed gaps in the historical record of instrumental music education, and in particular a dearth of biographical studies dealing with music educators in band field.

Three major microbial subpopulations from an industrial leachate system were characterized with respect to their bioremediation potential, and particular aspects of a cometabolically active subpopulation were determined.

The National Guard in America began in the Revolutionary War. The Texas units resulted from the earlier concept and emerged in 1835 to resist Mexican oppression. Following achievement of statehood, Texas militiamen served in the Mexican War, the Civil War, and the Spanish-American War. As the twentieth century began, Texans had a long history of service in reserve military organizations in spite of a prevailing attitude of contempt for citizen soldiers held by influential regular army officials.

Glycopeptidolipid (GPL) antigens isolated from Mycobacterium intracellulare were used to sensitize BALB/c mice. Primary footpad challenge of mice sensitized with GPL antigens suspended in phosphate buffered saline demonstrated an increased footpad swelling reaction.

Previous reports have shown that killed cells of S. aureus potentiate the lethal effect of crude staphylococcal alpha toxin for mice. In the present study this synergistic effect has been demonstrated with highly purified preparations of alpha toxin. Time studies indicate that the active principle does not appear to be released until approximately two hours following administration of the whole cells.

The purpose of this study is to bring together the information necessary to assess the Mixtec goldsmithing techniques and the designation of these techniques as a culmination of New World metallurgy. Historical and technological backgrounds are examined in depth.

Aspartate transcarbamoylase (ATCase) is encoded by the pyrBI genes in E. coli. Expression of these genes is reduced four-fold by attenuation when grown on uracil. Using plasmid, pRO1727. the pyrB and the pyrBI genes from E. coli were cloned into a P. putida pyrB auxotroph. A recombinant pyrB gene was recovered that encoded a functional hybrid ATCase with a molecular weight of 470 kDa.

This study investigated the β-subunit of the GABAa receptor and determine if there are changes in the primary sequence of the extracellular N-Terminal domain, which likely regulates GABA binding.

Muscle, hypodermis and gastrointestinal epithelium from adult female Ascaris lumricoides var. summ were found to contain serotonin based upon glyoxylic acid induced histofluorescence and indirect immunolabeling with an anti-serotonin monoclonal antibody conjugated to protein A-colloidal gold.

This dissertation research addresses the question of whether the issuance of the FASB and SEC proposals had any effect on the common stock values of oil and gas producers.

This study analyzes federal and state pollution control and abatement legislation and provides a one-volume working explanation of those laws applicable to business operations. This analysis is limited to legislation aimed at controlling air and water pollution, and solid waste management.

Twelve freshwater gastropod families, 39 genera and 70 fossil and Recent species are recognized and systematically treated. Keys to the families, genera and species were constructed and all species are illustrated. The purpose of this study was to synthesize and update the taxonomy, zoogeography, origins and correlations with drainage systems of the entire Recent and fossil freshwater gastropod fauna of Texas.

The holomorphology of ll life stages of 20 western Nearctic Isoperla and one Cascadoperla was studied over the 3-year period 1975-1978. One monotypicgenus new to science, Cascadoperla, is described, and Cascadoperla tricture (Hoppe) designated as the type species. The nymph, adult male and female, and ova are described and illustrated.
