The investigation presented is in two parts: a study of the mixed dimerizations of halogenated ketenes with non-halogenated ketenes and a study of the rearrangements of 8-chloro-8-methylbicyclo {4.2.0} oct-2-en-7-ones.

Trimethylsilylbromoketene was synthesized by the tri-ethylamine dehydrohalogenation of trimthylsilylbromacetyl bromide or chloride. This ketene was found not to undergo cycloaddition reactions with activated olefins, such as cyclopentadiene, ethyl vinyl ether and dihydropyan.

The Germans who immigrated to Texas in the 1830s, 40s, and 50s brought with them many and varied cultural institutions which they had known and enjoyed in Europe. As soon as the initial hardships of the frontier could be overcome, they eagerly established singing societies in the Lidertafel tradition. These organizations were to have a profound impact on music in Texas from about 1850 to the time of World War I.

Utilizing the debates of the German Reichstag, the proceedings of the SPD, the memoirs of the leading military and Marxist figures and the principal newspapers of the Second Reich and Weimar Republic, this dissertation attempts to show how the army chiefs and the socialist leaders of Germany altered their policies not only to promote their interests but also to protect the state.

The lecture recital was given on April 18, 1974. Some Mendelssohn organ works in manuscript were performed during the lecture to illustrate Mendelssohn's indebtedness to baroque models and his evolution as an organ composer.

The earthworms, Lubricus terrestris and Eisenia foetida, were used as non mammalian surrogate models to assess the immunotoxicpotential of xenobiotic to mammals. Assays were developed and optimized for detecting spreading activity and phagocytosis of rabbit red blood cell (RRBC), bacteria, and yeasts by macrophage-like coelomocytes of L. terrestris.

Efforts were made to (1) enumerate and isolate the intestinal bacteria of Ascaris suum; (2) identify those bacteria isolated; and (3) assess the ability of intestinal bacteria to produce serotonin.

The effect of ribavarin (1-β-D-ribofuranosyl-1,2,4-triazole-3-carboxamide), a synthetic nucleoside, on a series of cellular properties which characterize the transformed state was studied using normal rat kidney cells (NRK) and cloned derivatives transformed by a wild type avian sarcoma virus, B77-NRK, and by a temperature-sensitive mutant of the virus, LA31-NRK.

The (2+2) cycloaddition of ketenes and trimethylsilyl enol ethers was found to proceed in good yield to give trimethylsiloxycyclobutanones of unique and interesting regiochemistry and stereochemistry. As electron-rich activated olefins, the trimethylsilyl enol ethers readily reacted with the electron-deficient ketenes.

The effects of rat fibroblast interferon and a retinoid (Ro 10-9359) on the transformed state were investigated using normal rat kidney (NRK) fibroblasts and its derived cell lines, B77-NRK, transformed by temperature-sensitive mutants of Rous sarcoma virus.

Clinical evidence has demonstrated that the anxiolytic effects produced by the selective 5-hydroxytryptamine1A (5-HT1A) receptor agonist, gepirone, increase progressively over one to three weeks of treatment.

This study examines the α-adrenergic constrictor tone varies with intensity of exercise, the effects of coronary α1-adrenergic blockade on left ventricular contractile function and regional myocardial perfusion, and compares the effects of increasing coronary blood flow by removing α1-constrictor tone.

In this study the mouse tumor necrosis factor-alpha (TNF-α) was prepared by stimulating macrophage cell line RAW 264.7 with lipopoly-saccharide (LPS) obtained from Escheria coli strain 055:B5.

This study is an investigation of the relationships between music and the poetry of Wordsworth, Coleridge, Byron, Shelley, and Keats. Particularly it focuses on the nature of their musical subject matter and musical imagery in order to determine the extent to which they were influenced by aesthetic and philosophical musical theory, generally termed speculative music.
