Thesis advisor: James O'Toole / This thesis examines the extent of Jim Crow segregation in college football in the era immediately preceding World War II by focusing on three black stars: Wilmeth Sidat-Singh of Syracuse, Lou Montgomery of Boston College, and Leonard Bates of New York University. Sidat-Singh was passed off by Syracuse as a Hindu before his real ethnicity was revealed. Montgomery was benched by his Catholic university on six separate occasions, including two bowl games. Bates was the beneficiary of a massive student protest for his inclusion, but ultimately was benched by the supposedly liberal NYU. These benchings of northern players against southern teams shows the degrees the south went to in order to impose segregation on every level of society. Perhaps more importantly it shows how willing northern schools were to acquiesce to these southern demands in favor of expediency. / Thesis (BA) — Boston College, 2005. / Submitted to: Boston College.

Orientador: Elias Leite Mendonça / Resumo: Neste trabalho propomos uma base de operadores de projeção e transição de spin para tensores de rank-3. Utilizaremos essa base para determinar os coeficientes da densidade de lagrangiana do modelo de Singh-Hagen (SH). Forneceremos uma expressão geral para obtenção do propagador para teorias de rank-3 via tensor totalmente simétrico sem quebra de paridade. Além disso, realizaremos o processo de Imersão de Calibre de Noether (ICN) no modelo SH em D dimensões e verificaremos seu conteúdo físico. Por fim iremos verificar o conteúdo físico de um novo modelo de dubleto de spin-3 de sexta ordem obtido pelo processo de solda dos modelos auto-duais de quinta e sexta ordem que não necessitam de campos auxiliares. / Abstract: In this work we suggest a basis of spin projection and transition operators for rank-3 tensors. We use it in order to determine the coefficients of the Singh-Hagen model. We also provide a general expression for obtaining the propagator for rank-3 theories via full symmetric tensor without parity breaking. In addition, we perform the Noether Gauge Embendment (NGE) procedure on the SH model in D dimensions and verify its particle content. Finally we analyze the unitarity of a new sixth-order spin-3 doublet model obtained through the soldering approach of the fifth and sixth order self-dual models which do not require auxiliary fields. / Mestre

"Bombay is the future of urban civilization on the planet. God help us" (Suketu Mehta) Mit dieser Prophezeiung verweist Suketu Mehta in seiner diasporischen Reisereportage Maximum City: Bombay Lost and Found (2004) nicht nur auf die wachsende ökonomische Bedeutung der Millionen-Metropole Bombays, sondern thematisiert auch die 'degenerierten' Lebensformen außerhalb oder 'unterhalb' des stolzen monumentalen Raumes der wohlhabendsten postkolonialen 'neuen' Metropole. In ihrer Antrittsvorlesung am 28.04.2010 eruiert und verwendet Prof. Dr. Cecile Sandten, Inhaberin der Professur für Anglistische Literaturwissenschaft, die Begriffe "Metroglorification", "Diffuse Urbanism", das Postkoloniale oder den Palimpsestraum mit Bezg auf die so genannten "neuen" Metropolen. Die Veranstaltung beginnt um 19 Uhr im Hörsaalgebäude an der Reichenhainer Straße 90, Raum 113. Im Zentrum der Antrittsvorlesung stehen literarische und mediale Repräsentationen des Postkolonialen im urbanen Raum in den so genannten 'neuen Metropolen' wie Bangalore, Bombay, Delhi, Hongkong, Johannisburg, Kapstadt oder Lagos. In ihrer Vorlesung begreift Prof. Dr. Cecile Sandten die 'neuen Metropolen' als Palimpsesträume, in denen kosmopolitische bzw. globale, gleichsam individuelle und/oder kollektive Identitätsentwürfe auf vielschichtigen Bedeutungsebenen verhandelt werden. Diese Verhandlungen gelingen bzw. misslingen wiederum in Abhängigkeit von der Wechselwirksamkeit performativer und narrativer (Re-)Inszenierungen kolonialer Geschichte(n) und deren postkolonialen Transformationen und Dekonstruktionen. Vor dem Hintergrund urbaner Eigengeschichte(n) und exil-urbaner Fremdgeschichte(n), wie sie z.B. aus der Sicht von neuen Migrantinnen und Migranten oder (politischen) Flüchtlingen erzählt werden, wird dieses Phänomen anhand einer Auswahl an englischsprachigen literarischen und medialen Texten analysiert. Untersucht werden dabei die ungleichen Machtverhältnisse, die im postkolonialen (Stadt)Raum vorherrschen, als auch die vielfältigen Repräsentationen der metropolitanen Unterwelt auch im Sinne des 'Liminalraums', wie sich dieser im Zusammenhang mit z.B. illegalen Migrantinnen und Migranten, Slum-Bewohnern, Kriminellen und in Bezug auf korrupte Regierungen darstellt. Weiterhin soll durch die verschiedenen literarischen und medialen Protagonisten auch das benjaminsche Konzept des "Flaneurs" – in seiner Neuformierung hin zum 'postkolonialen Flaneur' – betrachtet werden.

Purpose: Despite many previous articles and tests on the subject “analysis methods for concrete slabs on ground subjected to concentrated loading” there is still uncertainty on which analysis method to use and if the results correspond to real failure loads. The purpose of this study has been to evaluate and compare different analysis methods for slabs on ground subjected to concentrated loading.Method: Initially literature studies was performed where different analysis methods were studied. Three methods were chosen based on different aspects. It was found that A. Losbergs (1961) method was mainly used in Sweden while other countries in Europe used Meyerhofs (1962) method. Rao & Singhs (1986) method has a similar approach compared to Meyerhofs but ads two different types of failure modes. Two peer re-viewed articles were also chosen from which secondary data could be retrieved. The articles described tests where concrete slabs were loaded until failure. The test condi-tions were used to perform calculations with the three analysis methods. A comparison was made between the test results and the results from calculations.Findings: It is concluded that there are some differences between Losbergs, Meyerhofs and Rao & Singhs analysis methods. Largely the three methods require the same input, they differ in selection of analysis solution, but despite a degree of variation of the calculation results the overall picture for the different loading cases are quite unified. For central loading all analysis methods result in a capacity lower than the test values, varying from 56% to 93% of the failure load. Concerning edge and corner cases the spread of results is even wider. Calculations for the reinforced slab results in a capacity higher than the test values while calculations for the plain concrete slab results in a capacity considerably lower than the test values.Implications: The results in this study indicates that the three analysis methods are applicable for internal loading. The spread of the results makes it difficult to estimate the margin to the actual failure load, but the safety factors according to Eurocode 2 should provide a safe failure margin. Regarding edge and corner cases it is more diffi-cult to draw conclusions due to the large spread of results. Further research and testing is needed.Limitations: The study is limited to three analysis methods and the results from two articles where two different concrete slabs were tested. Inclusion of additional analysis methods and articles with test results would expand the generalizability of the study. However due to the limitations of the extent of the study and disposable time this was not possible.Keywords: Meyerhof, Rao & Singh, Losberg, concrete slab on ground, concrete slab on grade, point load, concentrated load.

Swine barn air is a heterogeneous mixture of dust, bacteria and irritant chemicals including ammonia and hydrogen sulphide. Gram-negative bacteria are commonly found in swine barn air and significantly contribute to pulmonary disease in unprotected swine barn workers, through the endotoxin moiety, lipopolysaccharide (LPS). Toll-like Receptor-4 is the ligand for LPS. It is found on many cell types including monocytes, macrophages, neutrophils, endothelial cells, and to a lesser extent, epithelial cells. The severity and outcome of acute lung injury following barn air exposures depends upon the balance between epithelial and vascular endothelial repair mechanisms, including angiogenesis. Vascular Endothelial Growth Factor (VEGF) is an endothelial mitogen produced by mesenchymal and alveolar Type II epithelial cells and by activated bronchial airway epithelial cells. Research investigating the role of cytokines in angiogenesis has shown that close proximity of immune cells and endothelial cells modulates the production of various compounds that regulate vascular function. Given that LPS is the ligand for TLR4 there appeared to be a role for TLR4 in angiogenesis, particularly following endotoxin exposure. To determine whether this was occurring, we examined whether exposure to swine barn air alters vascular density in the lungs and the role of TLR4 using a murine model. Toll-like Receptor-4 wild-type (C3HeB/FeJ) and TLR4 mutant (C3H/HeJ) mice were obtained and exposed to swine barn air for 1-, 5-, or 20-days for 8 hours/day. Wild-type animals showed a 127% increase in vascular density after 20-days barn air exposure. Vascular Endothelial Growth Factor-A protein levels were decreased by 0.62-fold after one-day swine barn air exposure in wild-type animals, indicating that VEGF-A is being used as a pro-angiogenic mitogen. Transcription of VEGF-A mRNA was increased in wild-type animals after all swine barn air exposure periods. The receptor VEGFR-1 showed increased mRNA transcription over all time points. These effects were only observed in TLR4 wild-type animals, indicating that these effects are mediated by TLR4. Further, VEGF-A and VEGFR-1 appear to be involved in the manifestation of TLR4-induced angiogenesis in the lung.

The majority of signals, that need to be processed, are analog, which are continuous and can take an infinite number of values at any time instant. Precision of the analog signals are limited due to influence of distortion which leads to the use of digital signals for better performance and cost. Analog to Digital Converter (ADC), converts the continuous time signal to the discrete time signal. Most A/D converters are classified into two categories according to their sampling technique: nyquist rate ADC and oversampled ADC. The nyquist rate ADC operates at the sample frequency equal to twice the base-band frequency, whereas the oversampled ADC operates at the sample frequency greater than the nyquist frequency. The sigma delta ADC using the oversampling technique provides high resolution, low to medium speed, relaxed anti-aliasing requirements and various options for reconfiguration. On the contrary, resolution of the sigma delta ADC can be traded for high speed operation. Data sampling techniques plays a vital role in the sigma delta modulator and can be classified into discrete time sampling and continuous time sampling. Furthermore, the discrete time sampling technique can be implemented using the switched-capacitor (SC) integrator and the switched-current (SI) integrator circuits. The SC integrator technique provides high accuracy but occupies a larger area. Unlike the SC integrator, the SI integrator offers low input impedance and parasitic capacitance. This makes the SI integrator suitable for low supply voltage and high frequency applications. From a detailed literature study on the multi-bit sigma delta modulator, it is analyzed that, theneeds a highly linear digital to analogue converter (DAC) in its feedback path. The sigma delta modulators are very sensitive to linearity of the DAC which can degrade the performance without any attenuation. For this purpose T.C. Leslie and B. Singh proposed a Hybrid architecture using the multi-bit quantizer with a single bit DAC. The most significant bit is fed back to the DAC while the least significant bits are omitted. This omission requires a complex digital calibration to complete the analog to digital conversion process which is a small price to pay compared to the linearity requirements of the DAC. This project work describes the design of High-Speed Hybrid Current modeModulator with a single bit feedback DAC at the speed of 2.56GHz in a state-of-the-art 65 nm CMOS process. It comprises of both the analog and digital processing blocks, using T.C. Leslie and B. Singh architecture with the switched current integrator data sampling technique for low voltage, high speed operation. The whole system is verified mathematically in matlab and implemented using signal flow graphs and verilog a code. The analog blocks like switched current integrator, flash ADC and DAC are implemented in transistor level using a 65 nm CMOS technology and the functionality of each block is verified. Dynamic performance parameters such as SNR, SNDR and SFDR for different levels of abstraction matches the mathematical model performance characteristics.

Le présent mémoire porte sur l'emprise maternelle et l'absence de frontières qu'on observe dans les relations mère-fille conflictuelles dépeintes par certaines auteures francophones contemporaines. Ainsi, il sera question des romans Paradis, clef en main et Crève, maman! des Québécoises Nelly Arcan et Mô Singh, ainsi que du recueil de nouvelles Insecte, de la Française Claire Castillon. Nous verrons d'abord les mécanismes par lesquels s'instaure l'emprise maternelle, notamment par l'absence de frontières ou de limites adéquates entre mère et fille, ensuite les façons dont les filles tentent de se sortir de cette fusion avec la mère et, enfin, les manières dont l'écriture, voire la structure des textes, est travaillée par cette situation entre les deux femmes. Pour cela, nous nous appuierons sur des études psychanalytiques, littéraires et féministes. Il sera également question de travaux sur l'injure, puisqu'il s'agit de l'arme privilégiée par les protagonistes dans ce qui devient une guerre pour « sauver sa peau ». Nous concluons en effet que l'enjeu de cette emprise est majoritairement la peau puisque mère et fille se retrouvent à n'en posséder qu'une seule pour elles deux, dont la mère détient la plus grande part. La fille, victime d'emprise, perd son impression de cohésion et les frontières symboliques de son corps deviennent poreuses, en raison de cette peau partagée. Le comportement d'une mère qui refuse de respecter certaines limites avec sa fille mène celle-ci à basculer vers l'animalité, car elle n'est jamais une femme à part entière. Entre elles, toute réconciliation est impossible tant qu'elles doivent se partager cette peau puisqu'elles ne sont pas entièrement séparées. Se parler d'égale à égale, dans cette situation, est impossible. C'est souvent la mort qui effectue la séparation nécessaire entre les deux femmes et qui empêche ainsi la relation de se modifier. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Relation mère-fille, maternité, emprise maternelle, inceste, peau, injure.
