This thesis describes the synthesis and complexation of amino acid based chelants for technetium and rhenium. All of the chelates were of the NxSy type. An initial N2S2 diamido dithiol peptide of the type mercaptoacetic acid-serine-cysteine was synthesized and coordinated with both rhenium and technetium. The complexes were analysed by NMR spectroscopy and found to retain the benzyl moieties. Syn and anti diastereoemers were produced with one conformation preferred over the other. This was not true of another chelant RP294 supplied by Resolution Pharmaceuticals. The N2N1'S1 chelant consisted of dimethyl-glycine-serine-cysteineglycine and was a novel variation of the N2S2 tripeptide used initially. The coordination of this N3S chelant to technetium resulted in the formation of equal 1:1 quantities of diastereomers. Analysis was done by NMR spectroscopy and electrospray mass spectrometry. The two diastereomers were found to slowly interconvert and a mechanism for the interconversion proposed. The radiopharmaceutical RP128 (dimethylglycineserine-cysteine-glycine-threonine-lysine-proline-proline-arginine), of which the RP294 is the chelating portion, was coordinated to technetium. Analysis of the bifunctional chelant and its coordination complex by NMR spectroscopy demonstrated that the targeting portion of the molecule was unaffected by the technetium. Two diastereomers of the TcO(RP128) complex were found, as seen for the chelating portion of the molecule, TcO(RP294). / Thesis / Master of Science (MS)

The Back of the World is a novel about crime, performance, and the nature of employment in the 21st Century.

A novel antenna made of a spiral wire wrapped into a larger helical shape is introduced. The geometry of this antenna, which is a doubly helical structure, is fully described by five independent parameters, including two radial dimensions, two pitch angles, and the number of turns. Radiation properties of this antenna are examined both theoretically and experimentally. The Numerical Electromagnetic Code (NEC-2) is used to obtain simulation results. A large number of cases with different radii, pitch angles, and number of turns are investigated. Results for far-field patterns, gain, axial ratio, and bandwidth are presented. The influence of parameters on radiation properties are examined. Several prototypes of the antenna were constructed and tested using an outdoor antenna range. Measured far-field patterns are presented over a wide range of frequencies. The measured and computed radiation patterns are in good agreement. The results of this study indicate that the proposed antenna provides circular polarization and high gain over a wide frequency range. For example, when the number of turns is 10, a gain of 11-14 dB, a boresight axial ratio of less than 3 dB, and a half-power beamwidth of about 40 degrees are achieved over a 30% bandwidth. The side-lobe level for most cases examined is better than 10 dB below the main beam. A unique advantage of this antenna is its much smaller size compared with a conventional helical antenna made of straight wire shaped into a helix. Having about the same radiation characteristics, including gain, circular polarization, bandwidth, and side-lobe level, this new antenna occupies a volume more than 2.5 to 3 times smaller than the conventional helix. This reduction in size, which in turn may imply smaller weight and lower packaging and manufacturing costs, makes the proposed antenna very appealing to many communications and aerospace applications. / Master of Science

Thesis advisor: Robert Lehman / The scholarship surrounding the anglophone Bildungsroman has been to this point largely divided by national and periodized boundaries. This approach to the coming-of-age novel highlights tightly-knit clusters of texts that share geospatial contexts but precludes the possibility that texts from outside these demarcated groupings share essential features that might transcend the borders of nations and literary periods. In the supposed age of literary cosmopolitanism, it is perhaps time for a new approach to the Bildungsroman. I contest that, by approaching various Bildungsromane on the level of their form and structure, new constellations of texts emerge that bring forth new questions and challenges to the conventional narrative of the rise and fall of the Bildungsroman throughout the long history of the novel globally. Each of the texts I discuss fuses a common literary form–the oral tale, the Gothic, literary naturalism, the national allegory–with the coming-of-age novel which inflects and informs its familiar plot, creating cross-cultural and cross-temporal patterns as practitioners of the genre take it up in vastly different circumstances and contexts.  Each manifestation of these hybrid Bildungsromane represents new fields on which the experimental potentialities for individual subjectivity and agency in modernity might ensue, from the early 1840s to the turn of the twenty-first century. In texts which incorporate the chronotope of the oral tale, I argue that authors use the genre to create space for individual agency in a globalizing world. In the inclusion of the Gothic, I suggest, the Bildungsroman resituates the human on the periphery of the text, thrumming with increasingly animate places and things that crowd the individual subject out of her own development. I then question the entropy spirals present in literary naturalism as they temper and trouble the linear development plot, and offer insights into texts that use this fused form to preclude Bildung and texts that use the forces of naturalism to create subterranean structural narratives that reassert its latent potential. I then take the national allegory, a genre with a complex relationship to the Bildungsroman, and argue that the individual subject comes to hold an almost mythic position which comes to be either dissolved or monstrously reasserted in dark reflections of late colonial and postcolonial national imaginations. Finally, I argue that through fantastical realism, a utopian formal play emerges in the narration of the Bildungsroman that creates the narrative space for unique representations of multilayered, open-ended identities at the end of the text. / Thesis (PhD) — Boston College, 2024. / Submitted to: Boston College.

<p>This dissertation explores the ways in which British popular novels of the eighteenth century functioned as commodities. "Novel Addiction", the title of this dissertation has a double meaning: Addiction was a new conceptual framework developed during the eighteenth century in order to manage the increasing anxiety brought upon the culture of consumption, and the novel, one of the most popular commodities of the same period, was addictive. Both as successful commodities and efficient cultural agents, popular novels that were categorized as the sentimental or the gothic participated in the process of creating and disseminating models of addiction that warranted perpetual discipline. However, this discipline does not aim at preventing or eliminating addiction. It rather manages addiction as "habit" in a way that guarantees proliferation of the market economy. By employing the framework of addiction, I intend to reconfigure the role of the novel in the construction of individual and collective models of consumption-oriented subjectivity. </p><p>The first chapter begins with Eliza Haywood's Present for Women Addicted to Drinking where the author proposes novel-reading as the best cure for alcohol addiction, which allows me to explore a parallel between the phenomenon called the "gin craze" and the proliferation of print commodities. The second and third chapter discuss the sentimental novel and the gothic novel respectively focusing on the characteristics of each genre that make them addictive. The fourth and final chapter discusses Jane Austen's Northanger Abbey and Sense and Sensibility, which address and attempt to manage "novel addiction," a problem posed by the popular novels of her contemporaries.</p> / Dissertation
