Sikh Terrorism in India 1984-1990: A Time Series Analysis

Description: In recent times, religion has become a powerful force in giving legitimacy to terrorist actions. The present work considers this highly salient fact, as well as stresses the necessity to consider the historical and social contexts and group power resources in any meaningful analysis of violent protest movements. Quantitative rigor is combined with a sensitivity to context. Terrorism is operationalized by taking a time-based count of terrorist killings of innocent people. Regime acts of omission and commission are coded as time series interventions. The analysis also includes a continuous variable measuring the incidence of economic distress in Punjab. A case is also made for the superiority of Box- Jenkins time series techniques for the quantitative analysis of problems of this nature.

Magneto-Optical and Chaotic Electrical Properties of n-InSb

Description: This thesis investigation concerns the optical and nonlinear electrical properties of n-InSb. Two specific areas have been studied. First is the magneto-optical study of magneto-donors, and second is the nonlinear dynamic study of nonlinear and chaotic oscillations in InSb. The magneto-optical study of InSb provides a physical picture of the magneto-donor levels, which has an important impact on the physical model of nonlinear and chaotic oscillations. Thus, the subjects discussed in this thesis connect the discipline of semiconductor physics with the field of nonlinear dynamics.

The Offstage Effect: An Historical and Stylistic Perspective with Performance Considerations for Trumpet

Description: The present study does not attempt to present a complete or exhaustive survey of the myriad spatial orchestrational devices occurring in the symphonic and operatic repertoire. Rather, the study is limited to an examination of the specified use of the trumpet as an offstage instrument in selected representative works. The study's purpose is to identify trends in the use of this orchestrational device, to serve as an aid to the trumpeter in matters of interpretation, and to provide a practical reference for the solution of acoustical and technical problems common to the performance of spatially conceived music in the orchestral literature.

Preparation and Stereochemistry of Reactive Intermediates Containing a Silicon-Carbon Double Bond

Description: 1,1-Dimethyl-2-neopentylsilene reacted with the N-methylimine of benzophenone to give 1,2,2-trimethyl-3- neopentyl-4,4-diphenyl-l-aza-2-silacyclobutane, I, and 2,3,4,4a-tetrahydro-2,3,3-trimethyl-1-phenyl-4-neopentyl-2- aza-3-silanephthalene, II, in 35% and 20% yields, respectively. Compounds I and II did not serve as thermal silene precursors. Heating I and II to over 280°C did not yield 1,3-disilacyclobutanes. In the presence of 2,3- dimethyl-1,3-butadiene typical silene products were not obtained. However, I and II reacted rapidly with methanol at room temperature to give the ring-opened products (E)-2- methoxy-2,5,5-trimethyl-2-silahex-3-ene, III, 1,1- diphenyldimethylamine, IV, and 2-methoxy-2,5,5-trimethyl-3- (N-methylaminodiphenyl) methyl-2-silahexane, V.

Physiological Effects of Ascaris Suum Intestinal Microflora on 5-Hydroxytryptamine Level and Binding Sites in the Intestinal Epithelial Cells

Description: Serotonin (5-hydroxytryptamine, 5-HT) has been shown to activate carbohydrate metabolism in adult female Ascaris suum. Serotonin may be either absorbed directly from the environment or synthesized de novo from the absorbed L-tryptophan in adult female A. suum. The enzymes necessary for the synthesis of 5-HT have been identified in both intestine and muscle tissues. The serotonin absorbed from the environment is obtained either from the host's gastrointestinal contents or from the 5-HT producing bacteria in the intestine of A. suum. Numerous 5-HT producing bacteria were identified in the intestinal microflora. The physiological contributions of 5-HT producing bacteria to the 5-HT level, turnover and binding sites in the intestinal tissue of A. suum were investigated.

Evolution, Symmetrization, and Synthesis : The Piano Sonatas of Alberto Ginastera

Description: When Alberto Ginastera's oeuvre is viewed as a whole, an essential continuity between compositional ideas often appears in different works. This is especially apparent in the three piano sonatas, where each sonata represents an evolution and a condensation of ideas occurring in the previous one. The evolution of ideas throughout the three sonatas takes place through two primary processes. The first is a shift in cultural focus from reliance on Ibero-American material in the first sonata (1952) to Amerindian in the second (1981), to a synthesis of the two cultural elements in the third (1982). The second means of evolution from sonata to sonata is through a process of symmetrization. Along with constructions using symmetrical scales, material in each of the three sonatas is subjected to various symmetrical procedures which correspond musically to basic geometric symmetry types or operations (bilateral, rotational, and translatory, for instance). The decreasing number of movements evidences a negative dilatation of material, moving from four movements in the first sonata to three in the second, to one in the third. In each case, corresponding material from the previous sonata is integrated into the following sonata. Both independently and as a group the three piano sonatas exhibit "invariance under a transformation."

Isolation, Characterization and Physiological Studies of Cyanide-Utilizing Bacteria

Description: Ten bacteria capable of growth on the metal-cyano complex, tetracyanonickelate (II) {K2 [Ni(CN)J } (TCN), supplied as the sole nitrogen source, were isolated. Seven isolates were identified as pseudomonads while the remaining three were classified as Klebsiella species. In addition to TCN, all isolates were able to utilize KCN although it was significantly more toxic. The degradation of TCN was most complete when supplied at growth-limiting concentrations, did not occur when ammonia was present, and resulted in the formation of nickel cyanide [Ni(CN)2] as a degradation product.
