Facial Difference, Consumer Culture and Being 'Normal'Peacock, Rose, Sargeant, Anita R., Small, Neil A. January 2016 (has links)
Yes / The face is not the property of an individual; it is a key part of our communicating body. It is performed, in social interaction (Goffman, 1982) and seen and responded to within historicised and gendered ideals of the normal and of beauty. The normal and the beautiful have a particular resonance in a visually mediated consumer society, “looks matter”. But more than half-a million people in the UK have a significant disfigurement to their face (Changing Faces, 2007). This chapter explores the way facial difference illuminates debates on bodily representation. It explores how people living with visible facial difference invoke discursive formations of disfigurement (Garland-Thomson, 2009). It asks how we encounter and respond to facial difference and examines how close personal relationships can offer a source of support. The chapter contextualises the relevance of the face for communication and then examines implications for social selves in personal communities. Seventeen people living with visible facial difference were interviewed as part of a PhD study and interview extracts illuminate different aspects of the aesthetics of inclusion.

Selecting distending medium for out-patient hysteroscopy. Does it really matter?O'Donovan, Peter J., Kaponis, A., Makrydimas, G., Paschopoulos, M., Zikopoulos, K., Alamanos, Y., Paraskevaidis, E. January 2004 (has links)
No / The aim of this prospective randomized study was to evaluate the role of carbon dioxide (CO2) and normal saline for diagnostic accuracy in out-patient hysteroscopy. Women admitted to our Department in order to undergo total abdominal hysterectomy also underwent diagnostic hysteroscopy, 12¿24 h prior to surgery. The selection of distending medium was made after randomization. Two groups of patients were formed, group A (CO2; n=39) and group B (normal saline; n=35). More than half of the women in the study population were post-menopausal. Post-hysteroscopy, all women were asked to rank any symptom that they felt during the procedure on a 4-point scale (0 = none; 1 = mild; 2 = severe; 3 = inability to perform hysteroscopy). The hysteroscopic diagnosis was compared with the macroscopic findings and the histological examination of the surgical specimen after hysterectomy. The percentage who completed hysteroscopy was 89.74% within group A and 97.14% within group B. Most patients of both groups felt some pain of mild intensity. The diagnostic accuracy of hysteroscopy was similar for both media when major pathology [large polyps (group A 91.7%; group B 92.7%), myomas (group A 81.25%; group B 92.7%) and/or hyperplasia (group A 87.5%; group B 90.2%)] of the endometrial cavity was detected. In contrast, in cases of minor pathology (small polyps, mucosal elevations, crypts, hypervascularization), hysteroscopy with saline presented with significantly higher diagnostic accuracy (85.4%) compared with hysteroscopy with CO2 (64.6%). In out-patient hysteroscopy, CO2 and normal saline were comparable with regard to patient discomfort and for the detection of major pathology of the endometrial cavity. Normal saline seems to be the most appropriate medium for the detection of minor pathology of the endometrial cavity.

Estimation of vertical load on a tire from contact patch length and its use in vehicle stability controlDhasarathy, Deepak 30 June 2010 (has links)
The vertical load on a moving tire was estimated by using accelerometers attached to the inner liner of a tire. The acceleration signal was processed to obtain the contact patch length created by the tire on the road surface. Then an appropriate equation relating the patch length to the vertical load is used to calculate the load. In order to obtain the needed data, tests were performed on a flat-track test machine at the Goodyear Innovation Center in Akron, Ohio; tests were also conducted on the road using a trailer setup at the Intelligent Transportation Laboratory in Danville, Virginia. During the tests, a number of different loads were applied; the tire-wheel setup was run at different speeds with the tire inflated to two different pressures. Tests were also conducted with a camber applied to the wheel. An algorithm was developed to estimate load using the collected data.
It was then shown how the estimated load could be used in a control algorithm that applies a suitable control input to maintain the yaw stability of a moving vehicle. A two degree of freedom bicycle model was used for developing the control strategy. A linear quadratic regulator (LQR) was designed for the purpose of controlling the yaw rate and maintaining vehicle stability. / Master of Science

História da formação de professores em São Paulo (1875-1894): intersecções entre os ideais de professor e de escola / Teacher education history in São Paulo (1875-1894): intersections between teacher and school ideals.Perez, Tatiane Tanaka 14 November 2012 (has links)
Este trabalho pretende analisar a construção de uma cultura escolar a partir do conhecimento pedagógico em curso na Escola Normal de São Paulo, no final do século XIX. Partimos da premissa de que os saberes entendidos como necessários ao exercício do magistério são reveladores da constituição de uma cultura profissional docente e de representações acerca de um ideal de professor e de escola que se pretende formar. Tais conhecimentos podem ser identificados nos manuais impressos de formação de professores e em suas apropriações presentes nos discursos dos aspirantes à carreira do magistério, através dos exames realizados pela Escola Normal. O período delimitado para este estudo compreende duas décadas, de 1875 a 1894. O ano de 1875 corresponde à segunda abertura da Escola Normal momento em que, pela primeira vez, são realizados exames escritos na referida escola, destinados aos seus alunos e aos aspirantes às cadeiras de instrução pública primária. O ano de 1894 marca o início de um período de inúmeras mudanças na estrutura e organização da escola, além da mudança da Escola Normal para prédio próprio, à Praça da República. Nessa empreita, procuramos demonstrar a relação existente entre a expansão da instrução primária e as iniciativas de formação de professores em instituições específicas, sobretudo na Província de São Paulo no último quartel do século XIX. A partir da análise das provas e dos manuais pedagógicos, procuramos identificar uma concepção de educação, de instrução, de escola e de métodos de ensino que circulavam no período, por entender que tais aspectos são fundamentais para a compreensão do perfil de professor e de um modelo de escola que se pretendia formar. Por último, pretendemos trazer à tona um ideal de professor presente no ideário da época. No período em estudo, o professor possui figura central e exemplar na formação de hábitos e condutas desejáveis para a população. A partir do momento em que o Estado assume a responsabilidade pela instrução do povo, ele institui um controle mais rigoroso sobre o processo educativo e, consequentemente, sobre o professor. Ao torná-lo funcionário público sob tutela do Estado, é possível criar dispositivos de controle mais rígidos que dizem respeito aos processos de seleção do pessoal docente, às instituições autorizadas para sua formação, e ao estabelecimento de um conjunto de saberes exigidos para o exercício da profissão. Nesse processo de constituição profissional, é possível perceber mudanças e permanências, articuladas a um projeto civilizador por meio da disseminação de hábitos, condutas e práticas, tipicamente escolares que orientam e permeiam toda a sociedade. / This essay intends to analyze the construction of a school culture assessed from the pedagogical knowledge in course in the Escola Normal de São Paulo, at the end of the 19th century. It assumes the premise that the knowledge thought of as necessary for the teaching profession are revealing of a professional teaching culture and of representations of ideal teachers and schools that one intends to form. Such knowledge can be identified in printed formation manuals offered to candidates to the magisterium and its appropriations made by these candidates, read through their discourses in exams at the Escola Normal. The period of time delimited for this study comprehends two decades, from 1875 to 1894. The year of 1875 corresponds to the second opening of the Escola Normal moment in which, for the first time, written exams were taken in this school, offered to its students and to the candidates for public primary teaching. The year of 1894 marks the beginning of many changes in the structure and organization of the school, besides the reallocation of the Escola Normal to its own building. We seek here to demonstrate the relationship between the expansion of primary instruction and the initiatives in teacher education in particular institutions, above all in the Province of São Paulo in the last quarter of the 19th century. From the analysis of the exams and pedagogical manuals, we try to identify certain conceptions of education, instruction, schools and teaching methods that were then circulating, as we understand that such aspects are essential to the understanding of the teachers profile and of a model of school that was then intended. At last, we intend to bring to the surface an ideal of teacher in that times ideology. In the period under scrutiny, the teacher has a central and exemplary role in the formation of desirable habits and conducts for the population. From the moment that the State assumes the responsibility for the instruction of its people, it institutes a more rigorous control over the educational process and, consequently, over the teacher. Turning him into a public employee under the tutorship of the State, it becomes possible to create control mechanisms that are more rigorous concerning the selection process for the teaching personnel, the authorized institutions for its formation, and the establishment of a group of requisite knowledge for the profession. In this process of professional constitution, it is possible to notice changing and permanent factors, articulated to a civilizational project through the dissemination of habits, conducts and practices, typically the scholar ones that orient and permeate society as a whole.

Correção de normais para suavização de nuvens de pontos / Normal correction towards smoothing point-based surfacesValdivia, Paola Tatiana Llerena 08 November 2013 (has links)
Nos anos recentes, suavização de superfícies é um assunto de intensa pesquisa em processamento geométrico. Muitas das abordagens para suavização de malhas usam um esquema de duas etapas: filtragem de normais seguido de um passo de atualização de vértices para corresponder com as normais filtradas. Neste trabalho, propomos uma adaptação de tais esquemas de duas etapas para superfícies representadas por nuvens de pontos. Para isso, exploramos esquemas de pesos para filtrar as normais. Além disso, investigamos três métodos para estimar normais, analisando o impacto de cada método para estimar normais em todo o processo de suavização da superfície. Para uma análise quantitativa, além da comparação visual convencional, avaliamos a eficácia de diferentes opções de implementação usando duas medidas, comparando nossos resultados com métodos de suavização de nuvens de pontos encontrados a literatura / In the last years, surface denoising is a subject of intensive research in geometry processing. Most of the recent approaches for mesh denoising use a twostep scheme: normal filtering followed by a point updating step to match the corrected normals. In this work, we propose an adaptation of such two-step approaches for point-based surfaces, exploring three different weight schemes for filtering normals. Moreover, we also investigate three techniques for normal estimation, analyzing the impact of each normal estimation method in the whole point-set smoothing process. Towards a quantitative analysis, in addition to conventional visual comparison, we evaluate the effectiveness of different choices of implementation using two measures, comparing our results against state-of-art point-based denoising techniques. Keywords: surface smoothing; point-based surface; normal estimation; normal filtering.

Estudo da transição do regime de desgaste moderado para o desgaste severo a seco e sob o regime de lubrificação limítrofe. / Study of the mild and severe wear transition in dry wear and boundary lubricated wear.Rovani, Ane Cheila 11 June 2014 (has links)
Os mecanismos do desgaste e atrito que ocorrem durante o desgaste por deslizamento, bem como, a transição do regime do desgaste moderado para o desgaste severo, são influenciados pela força aplicada, rugosidade, temperatura e umidade, sendo estas variáveis frequentemente estudadas. Entretanto, a avaliação da remoção de debris durante o deslizamento e a influência do aditivo lubrificante, em regime limítrofe/quase seco (e.g. Ácido Esteárico C18H32O2) ainda são necessários maiores entendimentos sobre os mecanismos de desgaste e também a força na qual ocorre a transição do regime do desgaste moderado para o desgaste severo durante o deslizamento. Para os testes a seco, com e sem a remoção dos debris, foram realizados ensaios tribológicos convencionais com as duas durezas de disco, 435 e 530 HV30. Os resultados mostraram que a transição do regime de desgaste é influenciada pela dureza e pela remoção dos debris. A influência da dureza é observada apenas quando os ensaios convencionais são realizados, nos quais foi observado que o aumento da dureza do contra corpo estende a transição do desgaste moderado para o severo em forças maiores. A remoção dos debris aumenta a extensão da força para ocorrer a transição moderado/severo. Para os testes lubrificados, foram realizados ensaios com a dureza de disco de 530 HV, variando a concentração do ácido esteárico. Os resultados mostram que o aumento da concentração do aditivo e da força normal aplicada são varáveis determinantes para a redução do coeficiente de atrito. A ação do aditivo lubrificante é fundamental nas forças baixas, sendo que nas forças elevadas apenas o aumento da força normal é suficiente para manter o baixo coeficiente de atrito. Adicionalmente, para as elevadas forças aplicadas, o filme lubrificante falha em função do tempo de deslizamento, e maiores concentrações de aditivo são necessárias para manter o coeficiente de atrito constante. / The wear and friction mechanisms that occur during the sliding wear, as well as the transition from mild to severe wear regimes are influenced by the normal load applied, roughness, temperature and humidity, the variables more frequently studied. However, the assessment of debris removal during the sliding wear and oil influence with lubricant additive (e.g. Stearic Acid C18H32O2) in the boundary/dry lubrication needs further understanding of the mechanisms and the load that occur a wear transition from mild to severe wear. The aim in this work is the characterization and evaluation the contact surface without debris in sliding surface (cleaning of the wear track) and the wear surface in boundary lubrication tests. The materials studied are: the pin AISI 4140 - 435 HV30 steel and the disc AISI H13 - 435 e 530 HV30 steel. Firstly were made conventional tribological tests with two disc hardness. Then, tests with the cleaning of the wear track were made. The results showed that the hardness and the absence of debris influence in the wear transition regime. The hardness influence is observed only when the conventional tests were made. When the counter body hardness increased, the transition from mild to severe wear extends to greater loads. The debris influence was evidenced in tests with the cleaning of the wear track, and showed that greater loads are needed from mild to severe wear transition. For the lubricated tests, the hardness of the disk was 530 HV. The results shown that the concentration of the lubricant additive and the normal load applied are determinant variables to decreasing the friction coefficient. The lubricant additive action is critical in low loads, and in high loads only the increasing of the load is needed to maintain the low friction. In addition, in the high load applied, the failure of the lubricant film occurs with the increase of the sliding time, and higher additive concentrations are needed to maintain constant the friction coefficient.

Doença de Chagas: uma biografia / Chagas disease: a biographyKoide, Kelly Ichitani 09 March 2017 (has links)
A presente investigação constitui um estudo de caso sobre a tripanossomíase americana, conhecida como doença de Chagas, em seus aspectos epistemológicos e sociais, articulados através da análise de diferentes valores envolvidos nas pesquisas sobre essa enfermidade. Na elaboração de uma biografia procuramos enfatizar dois aspectos dessa patologia. Por um lado, que a tripanossomíase americana pode ser interpretada como um agente histórico, na medida em que a identidade dessa entidade nosológica não pode ser dissociada de sua caracterização científica e social, tampouco reduzida a apenas uma dessas dimensões. Por outro lado, colocar a doença como protagonista dessa história nos permite evidenciar de que modo o predomínio da narrativa das instituições médicas e científicas legitimou a invisibilização da perspectiva das pessoas afetadas por essa patologia. A primeira parte da tese está centrada sobre a faceta científica e médica da doença, a qual permitiu que a nova patologia humana fosse estabelecida como um fato. Com relação aos aspectos sociais da doença, estes são focalizados na segunda parte da tese, onde examinamos as ideias envolvidas nas representações dos trópicos e das populações rurais como sinônimos de atraso. / The present investigation is a case study of American trypanosomiasis, known as Chagas disease, in its epistemological and social aspects, articulated through an analysis of the different values involved in research on this disease. In the elaboration of a biography, we aim to emphasize two aspects of this pathology. On the one hand, American trypanosomiasis can be interpreted as a historical agent, to the extent that the identity of this nosological entity cannot be dissociated from its scientific and social characterization, nor can it be reduced to just one of these dimensions. On the other hand, to put the disease as the protagonist of this history allows us to show the ways in which the predominance of medical and scientific institutions narrative has legitimated the invisibility of the perspectives of the ones affected by this pathology. The first part of this thesis is centered on the scientific and medical facet of the disease, which allowed the new human pathology to be established as a fact. The social aspects of the disease will be focalized in the second part of the thesis, where we examine the ideas involved in representations of the tropics and of rural populations as synonyms of backwardness.
