Esta tese investiga o tema da figuração do estrangeiro nas narrativas: Relato de um certo oriente (1989), Terra Sonâmbula (1992), Dois irmãos (2000) e O outro pé da sereia (2006), respectivamente de Milton Hatoum e Mia Couto. Esses textos são lidos com os aportes teórico-metodológicos da Literatura Comparada e dos Estudos Pós-coloniais, içando pontes de diálogo entre as reflexões de Homi Bhabha, Edward Said, Édouard Glissant, Mary Louise Pratt, Walter Mignolo, Julia Kristeva, Tzvetan Todorov, Tania Carvalhal, Abdala Junior, Zilá Bernd, Maria Zilda Ferreira Cury, Jane Tutikian, Ana Mafalda Leite, Laura Padilha, Marli Fantini, dentre outros de fundamental relevância a esse construto. Com o auxílio dessa sintaxe crítica, no primeiro e segundo capítulos, mapeiam-se os fluxos comunitários e as paisagens literárias dos quatro romances; no terceiro, cartografam-se os lugares do narrar de RCO e TS, analisando como os narradores mediadores conectam geografias planetárias; e no quarto, topografam-se as cenas do des(re)territorializar de DI e OPS, examinando de que maneira os narradores figuram as errâncias, os limiares e os percursos transfronteiriços. Como lugares de passagens heterogêneas, essas quatro narrativas velejam nas águas do próprio e alheio, pintando a cartografia da paisagem brasileira/moçambicana em movimento contínuo de des(re)territorialização do dentro-fora da rede de contato intercultural. Entre o ir e vir propiciado pelo intercâmbio com outros saberes e práticas intercontinentais, os narradores desenham traços, tranças e travessias do dentrofora e fora-dentro do imaginário transatlântico, figurando o estrangeiro como hiato rizomático que interliga, disjuntivamente, a geografia do encontro de personagens que se reconhecem múltiplas, imersas na trama de culturas em errância. A travessia das personagens, longe de separá-las, estigmatizá-las e engessá-las, testemunha, pontualmente, como o dentro-fora do nacional híbrido e o fora-dentro estrangeiro cindido encontram-se no porto simbólico da estrangeiridade. A configuração desse lugar de estranhamento dentro de si mesmo consubstancia-se na dicção de vozes que deferem o jogo de estar entre os labirintos dos mapas da multiplicidade de olhares. Habitando posições intervalares, os narradores e personagens de RCO, TS, DI e OPS movem-se entre passagens, itinerários e paisagens culturais que instauram a poética do dentro-fora e fora-dentro das redes de solidariedade plurais. Isto é, o eu que narra e o eu narrado navegam, simultaneamente, pela canoa do imaginário da mobilidade cultural, aprendendo a habitar o movimento transversal e a zona friccional das alteridades. Do trânsito pelo espaço medial, tanto os narradores como as personagens desviam-se da densidade da lógica imóvel, encontrando na conjuntura da velocidade brechas para rasurarem qualquer tentativa de reconstrução do trajeto de início ou fim da alteridade. Ao contrário, eles exploram a estética do movimento para se des(re)territorializarem entre imaginários embalados pela dinâmica do dentro-fora e fora-dentro na trama instável de fluxos, subjetividades e histórias múltiplas. Nesse sentido, a figuração do estrangeiro é uma problematização possível à medida que traz, enquanto epicentro argumentativo, os atravessamentos movediços do dentro-fora e fora-dentro das relações interculturais. Em sua natureza performativa, o estrangeiro impulsiona o fluxo da heterogeneidade e mutabilidade das vozes, dos imaginários, dos contatos e das rasuras do eu que narra e do eu narrado. Assim, cartografar os limiares da canoa na letra de Milton Hatoum e Mia Couto é habitar o movimento da travessia de sujeitos que surfam nas ondas de entre-mundos da errância em devir. / This thesis investigates the issue of foreign figuring in the narrative: Relato de um certo oriente (1989), Terra Sonâmbula (1992), Dois irmãos (2000) and O outro da sereia (2006), respectively by Milton Hatoum and Mia Couto.

To this end, before, it was made needed a theoretical overview that elucidate the marks of colonialism European in African social context to then understand the remoteness both women, the indigenous cultures in Africa. Bringing the concept of Animist Realism proposed by Pepetela and invigorated by Harry Garuba, we enter the animistic conception of African world, as well as to propose reflections on patriarchy could also observe the marginal condition to which women are subjected in Mozambican society. Thus, when we consider that in Africa the social and cultural issues are intrinsically linked to the psychic representation of reality, the thread this analysis is to find aspects of Animist Realism weaving the representations of women in the novel in question. / Nesta dissertação nos dedicamos à leitura do romance do escritor moçambicano Mia Couto, A confissão da leoa, com o intuito de enlaças dois aspectos que aparecem de forma acentuada na produção literária do autor: o Realismo Animista e a representação do feminino. Para isso, antes, se fez necessário um apanhado teórico que elucidasse as marcas do colonialismo europeu no contexto social africano para então compreender a situação periférica tanto da mulher, quanto das culturas autóctones em África. Trazendo o conceito de Realismo Animista, proposto por Pepetela e avigorado por Harry Garuba, adentramos na concepção anímica de mundo africana, assim como, ao propor reflexões acerca do patriarcalismo pudemos observar também a condição marginal à que a mulher é submetida na sociedade moçambicana. Desse modo, ao considerarmos que em África as questões sociais e culturais estão intrinsecamente ligadas à representação anímica da realidade, o fio da meada desta análise é encontrar os aspectos do Realismo Animista que tecem as representações da mulher no romance em questão.

A partir dessas abordagens, em especial da identidade nacional e cultural, examina a identidade africana no contexto pós colonial, assim como faz a caracterização desse período. Para isso, analisa as formações identitárias em três personagens centrais das obras Um rio chamado tempo, uma casa chamada terra (2003), O último voo do flamingo (2005) e O outro pé da sereia (2006) do autor moçambicano Mia Couto, destacando as influências da colonização, o contato com outra cultura e o resgate de valores autóctones. As personagens selecionadas passaram pela experiência do deslocamento e, em algum momento da sua vida, afastaram-se da terra natal. Esses movimentos direcionam para as implicações e os desdobramentos na constituição de suas identidades. Desse modo, o estudo evidencia, entre os embates do legado europeu, da tradição e da modernidade globalizada, as reconfigurações identitárias e, principalmente, o surgimento dos novos sujeitos culturais africanos. / The study presents a reflection on the concept of identity and its compositions, such as national, social, cultural and ethnic identity from the perspective of several different heorists from different areas. From these approaches, in particular the national and cultural identity, the African identity in the postcolonial context is examined, as well as the characterization of that period. For this, it analyzes the identity formations in three central characters of the works A River Called Time, A House Called Earth (2009), The Last Flight of the Flamingo (2005) and The Mermaid’s Other Foot (2006) by the Mozambican author Mia Couto, highlighting the influences of colonization, the contact with another culture and the redemption of native values. The selected characters had the displacement experience and, at some point in their lives, moved away from homeland. These movements direct to the implications and ramifications in the constitution of their identities. Thus, the study shows, the clashes between the European legacy, tradition and global modernity, the identity reconfigurations, and, especially, the emergence of new African cultural subjects.

Infections with dengue viruses (DENV) constitute both a global problem as well as locally in Florida. DENV comprise four distinct serotypes of single-stranded RNA viruses and belong to the family Flaviviridae. DENV are among the most medically important arboviruses in the world and cases may currently exceed 400 million per annum. Additionally, dengue established its first recorded endemic transmission cycle in the state of Florida in over a half century, first within the Florida Keys during 2009-10 followed by an unrelated outbreak in Martin County in 2013. The clinical profile of DENV infections ranges from a mild febrile illness to severe illness including hemorrhaging and/or shock, occasionally leading to death. Asymptomatic and mild cases also play a role in maintaining transmission cycles. The early diagnosis and management of patients at the clinical level have both proven to be major obstacles in the control of DENV and are important at both the individual and community levels. Individually, the proper management of patients that will progress to severe illness demands that they are identified in order to receive supportive treatment and mitigate associated morbidity and mortality. At the community level, early diagnosis may reduce transmission by limiting the possibility of vector contact with viremic individuals. Early diagnosis is dependent on the detection of viral markers, while a number of host factors may inform prognosis. The microsphere-based immunoassay (MIA) is capable of detecting up to 100 different targets in a single sample and therefore would be useful as a single assay for determining both. This study attempted to develop a diagnostic and prognostic MIA using the DENV NS1 glycoprotein and 5 host markers as targets. For the purposes of DENV NS1 detection in MIA, a set of monoclonal antibodies (mAbs) were subjected to immunoprecipitation and/or Western blot analysis in order to determine immunoreactivity. Two mAbs, 3A5.4 and 3D1.4, were chosen for use in MIA as a capture antibody and a detection antibody, respectively, and the results compared to a commercially available DENV NS1 ELISA. The 5 markers chosen for MIA trials included GM-CSF, IFN-γ, IP-10, IL-10, and MCP-1 and were selected from a panel of 27 markers screened initially in two in vitro models of DENV infection in addition to serum samples. The two cell lines investigated were HPMEC ST1.6R and u937 as both are thought to play important roles in models of DENV pathogenesis. The results of the DENV NS1 detection MIA were initially promising but were ultimately unsuccessful. When measuring host markers in the MIA, results pointed towards certain profiles that may be of future use. IL-10 was found to be elevated in a statistically significant manner in DENV qRT-PCR+ samples (p=0.035) when compared to negative sera. MCP-1 elevation was found to be of borderline significance (p=0.058). Other potential markers based on the results reported here include IP-10, IL-6, IL-8, VEGF, and RANTES. The ultimate goal of measuring host markers is to gain the ability to differentiate patients that will progress to severe illness from those that will recover. In conclusion, despite the failure of the MIA to detect DENV NS1 in human sera, our results in determining host markers and developments leading to successful DENV NS1 detection ELISAs elsewhere lead us to believe that this approach remains promising. Major drawbacks of this study included the lack of samples from patients that experienced severe DENV illness as a comparative group in addition to small sample sizes. Future goals should include determining the reasons for the failure of the MIA in detecting DENV NS1, selecting a panel of appropriate markers to differentiate non-severe from severe cases of DENV prior to progression, and optimizing the inclusion of these markers to an appropriate number.

The advent of electrospray ionization enabled the study of intact protein complexes via MS. For example, in the mid-1990s, the observation that viruses can survive after entering the gas-phase and still retain activity was shown. Advances in sample preparation methodologies, mainly native MS, allowed for the preservation of large non-covalently bound complexes, which led to structural characterization studies that were previously unachievable. However, native MS suffers from complications arising from inherent heterogeneity and severe salt adduction. Consequently, the spectra can consist of broad and overlapping peaks that may even preclude the ability to obtain a mass measurement. This dissertation will focus on a gas-phase technique to address highly complex native MS scenarios that give rise to poorly resolved signals using the E. coli ribosome as one model system. Moreover, brief discussion of improvements made on our QToF platform (SCIEX 5600) will be compared with other state-of-the-art instruments. Lastly, other applications to our ion/ion reaction workflow will be explored.

The ladle metallurgical furnace (LMF) is a very flexible and common unit operation found in most steelmaking melt shops, and enables the adjustment and fine-tuning of molten steel's composition and temperature prior to casting. Despite the importance of ladle metallurgy to the overall steel making process very little has been achieved in the way of advanced ladle control. Limited sensors are available to monitor heat progress during refining and current control methods involve manual procedures. This thesis represents part of an ongoing study on the modelling of a full-scale LMF in real-time with the forward goal of improved control and optimization. The first part of this thesis details a vision-based sensor for analyzing ladle eye dynamics online using a multivariate image analysis (MIA) technique based on principal component analysis (PCA). Predictive capabilities of the developed model are demonstrated using previously published cold model data over a wide range of operating variables. Further, preliminary work has confirmed the ability of the sensor for potential use in an industrial setting. The second part of this study concerns the development of metallurgical models for assessing the state of a ladle metallurgical furnace. Specifically, a multi-component kinetic model in combination with developed slag and steel thermodynamic solution models were used to quantitatively describe the kinetics of slag-metal reactions within 41 industrially sampled heats at ArcelorMittal Dofasco's LMF#2. Metal phase mass transfer coefficients for all elements in steel were assumed to follow the empirical relation derived from measured sulphur contents, while slag phase mass transfer coefficients were calculated by fitting the ratio of k^Mm/ k^MxOysl to the experimental results. On the basis of the fitted results, slag phase mass transfer coefficient correlations were evaluated using linear regression. Computed results from the model using these slag phase mass transfer coefficient correlations were found to be consistent with the experimental data. In regard to the developed thermodynamic solution models, original contributions to the modified interaction parameter formalism and cell model are presented. As process model predictions are invariably uncertain, the final part of this work involves the use of a stochastic model (extended Kalman filter) to account for process disturbances, model-mismatch and other sources of uncertainty that may result in significant error propagation causing poor process control and plant economics. Several case studies were performed to illustrate the effectiveness of the extended Kalman filter and its application to optimal sensor selection was introduced. / Thesis / Doctor of Philosophy (PhD)

In this way, the goals are to demonstrate how some aesthetic resources that the novel uses, such as the satire, the uncommon, the oral tradition and the discursive construction of the difference, work as mechanisms of expurgation of a political corruption and contribute to the fiction to be a way of promoting the catharsis of a postcolonial locus. / Este trabalho pretende analisar o romance O último voo do flamingo, de Mia Couto, por meio da teoria pós-colonial, demonstrando como a narrativa constrói uma crítica política à administração de uma pequena vila chamada Tizangara, lida como possível metonímia de Moçambique. Nesse sentido, os objetivos são demonstrar como alguns recursos estéticos que o romance utiliza, como a sátira, o insólito, a tradição e a construção discursiva da diferença, funcionam como mecanismos de expurgação de uma corrupção política e contribuem para a ficção ser um modo de promover a catarse de um locus pós-colonial.

Throughout the time, many borders were raised and intensified antagonism between literature and history. At the same time, the explanatory models that have defined this knowledge passed to be questioned. The limits between science and art, the erudite and the popular as well as the relations of knowledge and power were problematized and they gave to reason and to the reality a greater importance, to the detriment of subjectivity and scientific fiction watched by per si, to establish an intimate process between literature and history. And it is through these discussions focused on the correlation between these two areas of knowledge, we have developed this work, taking as object of study the literary work Um rio chamado tempo, uma casa chamada terra, of the Mozambican Mia Couto. Narrative which shows echoes of the Mozambican literary tradition, targeted by the materiality of the world, is other words, for economic reasons, subjective, inter-subjective of power and by historical perspectives of culture, without forgetting to show the permeability of literature and real (story), seeking constructive and innovative dialogue, rather contaminated by memory. To establish the discussion on African literature, especially Mozambican, we sought grounds on Maria Fernanda Afonso, Ana Mafalda Leite, Pires Laranjeiras, among others. It is also adhere to the theoretical framework guiding principles of Postcolonial Studies of hybridization notions colonialism and present the ideas of its main authors like Albert Memmi, Homi Bhabha, Frantz Fanon and Stuart Hall. Then we detached the literary text of the encounter with history, drawing on Aristotles thoughts, in order to demonstrate that a fictional work is not limited only to tell what happened, but to observe what could have happened too, from the perspective verisimilitude. Hayden White also helps us to state that the plurality of meanings of literary and historical texts accrue from contextualization, in a view of, there is a dynamic that specifies the literary art and the construction of the historical text, wich adrheres, it transforms or breaks theirs significant loads, through a polysemic speech, intentionally, and, in most cases, selective. / Ao longo dos tempos, muitas fronteiras se erigiram e intensificaram o antagonismo entre literatura e história. Ao mesmo tempo, os modelos explicativos que definiram esses saberes passaram a ser indagados. As fronteiras entre a ciência e a arte, o erudito e o popular, bem como as relações de saber e poder foram problematizadas e deram à realidade e à razão uma maior importância, em detrimento da subjetividade e da ficção científica vistas de per si, ao estabelecer um processo de intimidade entre a literatura e a história. E é por meio dessas discussões, voltadas para a correlação entre essas duas áreas do saber, que desenvolvemos o presente trabalho, adotando como objeto de estudo a obra literária Um rio chamado tempo, uma casa chamada terra, do moçambicano Mia Couto. Narrativa que apresenta ecos da tradição literária moçambicana, alvejados pela materialidade do mundo, ou seja, por questões econômicas, subjetivas, intersubjetivas de poder e por perspectivas históricas de cultura, além de evidenciar a permeabilidade da literatura e do real (história), em busca de um diálogo construtivo e inovador, assaz contaminado pela memória. Para estabelecer a discussão sobre a Literatura africana, principalmente, a moçambicana, buscamos fundamentos em Maria Fernanda Afonso, Ana Mafalda Leite, Pires Laranjeiras, entre outros. Aderem-se também ao referencial teórico os princípios norteadores dos estudos pós-coloniais em torno das noções de hibridização e colonialismo presentes nas ideias dos seus principais autores, como Albert Memmi, Homi Bhabha, Frantz Fanon e Stuart Hall. Em seguida, destacamos o encontro do texto literário com a história, recorrendo aos pensamentos de Aristóteles, com o objetivo de demonstrar que uma obra ficcional não se limita apenas a contar o acontecido, mas também a observar o que podia ter acontecido, sob a ótica da verossimilhança. Hayden White também nos ajuda afirmar que a pluralidade de significações dos textos literários e históricos decorre de inúmeras contextualizações, porquanto há uma dinâmica que especifica a arte literária e a construção do texto histórico, que adere, transforma ou rompe as suas cargas significativas, por meio de um discurso polissêmico, intencional e, na maioria das vezes, seletivo.

[pt] A tese discute e analisa procedimentos de escrita em obras de três autores de língua portuguesa, investigando seus modos de narrar a partir de elaborações discursivas lacunares, hesitantes e provisórias. A partir da leitura das obras, a tese apresenta um quadro preliminar das relações entre os personagens e o que nomeamos a sua voz possível, encenada por meio de diferentes materializações narrativas. Nos autores selecionados, é possível identificar vozes múltiplas, sobrepostas e reverberativas, que ora se desdobram na transgressão dos discursos, ora atuam lateralmente e encaixando-se precariamente umas às outras. As análises empreendidas buscam oferecer um esboço para o conceito de voz possível como dispositivo de composição de personagens que, como sujeitos da contemporaneidade, se revelam descentrados, precários e lacunares principalmente em suas próprias narrativas. / [en] This thesis discusses and analyzes the writing procedures in works of three Portuguese-language authors, investigating their narrative forms as elaborations of a lacunar, hesitating and unstable discourse. From the reading of the works, the thesis presents a preliminary view of the relationship between the characters and what we call their pursuable voice, staged by means of different narrative materializations. In the chosen authors, we could identify multiple overlapping and reverb voices, which sometimes are revealed along transgression on discourse and sometimes operate laterally and poorly fit together. The analysis undertaken provides an outline for the concept of pursuable voice as a composition device to the characters who, as contemporary speakers, reveal themselves disoriented, unstable and lacunar mainly in their own narratives.
