Para tal, são utilizados materiais depositados em coleções paleontológicas de instituições de ensino e pesquisa, enriquecidos pela realização de atividades de coleta na bacia em questão. O material obtido é morfologicamente descrito e, através de estudos comparativos, uma proposta taxonômica é apresentada. A partir da realização de dois trabalhos de campo à região de estudo, foi possível confirmar, atualizar e rever o posicionamento estratigráfico/geocronológico da ocorrência de mosassauros na Bacia Pernambuco-Paraíba e levantar com maior exatidão sua associação paleofaunística. Assim resgata-se e amplia-se consideravelmente o conhecimento sobre estes répteis brasileiros, complementando as poucas referências na bibliografia. Os estratos sedimentares que contêm a paleofauna em análise são geologicamente caracterizados, apresentando-se uma resenha dos conhecimentos constantes da literatura científica, acrescida pelos dados coletados... / This dissertation carries out a survey of the occurrences of the mosasaurid marine lizard fauna from the Pernambuco-Paraíba basin of the Northeastern Brazil. Specimens housed in paleontological collections from several institutions have been examined and new material from the mentioned basin has been collected. The specimens are described and compared and a new taxonomic proposal is presented. Based on two field trips to the mentioned area, the stratigraphic and geochronologic occurrences of mosasaurs in the Pernambuco-Paraíba basin could be confirmed, updated, and revised. Furthermore, a better understanding of the paleofaunistic association of those creatures was obtained. This study recovers, expands, and complements the limited information so far available in the literature about the Brazilian mosasaurid taxóns. The sedimentary strata containing the studied fauna are characterized and a summary of the information available in the scientific literature...

Orientador: Hélio Langoni / Coorientador: Marcia Almeida Melo / Banca: Rodrigo Costa da Silva / Banca: Virginia Bodelão Richini Pereira / Resumo: A Leishmaniose Visceral Canina (LVC) é uma zoonose que acomete canídeos, constituindo-se um grave problema de saúde pública, tendo em vista que é o cão a principal fonte de infecção da doença para humanos no ciclo doméstico. A proximidade do cão tem sido referenciada como um importante fator de risco para a doença. É endêmica em diversas regiões do Brasil, incluindo o Estado da Paraíba. Em Campina Grande-PB, no período de dezembro de 2011 a fevereiro de 2012 foi realizado inquérito soroepidemiológico para Leishmania spp. em cães por meio de sorologia e pesquisa do DNA do parasita pela biologia molecular, enfocando a sua distribuição geográfica e correlacionando os fatores de riscos e socioeconômicos. Dos 391 cães estudados, 33% apresentaram resultado positivo para a pesquisa de anticorpos para leishmania spp. na RIFI e 4,34% ao ELISA, e 2% para a pesquisa de DNA do parasita no sangue pela PCR. Houve diferença estatística significante para contactantes (P=0,02) e (OR=4,1). A RIFI com antígeno de L. major, mostrou-se como um bom teste confirmatório, podendo ser utilizado como contra prova do ELISA, que apresentou sensibilidade de 39,4%. A associação entre os dois testes e a co-positividade foi de apenas 52%, necessitando de outra prova confirmatória. Já para a confirmação de negatividade na RIFI, o ELISA foi considerado seguro, apresentando um índice de 96,7%. O uso da PCR de sangue total apresentou baixa sensibilidade e baixa concordância com a RIFI, não sendo indicado como teste primário e mostrou-se eficiente na contra prova. Os estudos mostram que a LVC tem-se adaptado à zona urbana, portanto de forma endêmica, concluindo-se que a diversidade de provas diagnósticas, melhora a detecção de animais positivos, aspecto excelente para o controle da LVC em determinadas áreas, além de evitar a eutanásia de cães falsos positivos / Abstract: The Canine Visceral Leishmaniasis (CVL) is a canidae zoonosis, which infects dogs and other mammals, as humans, becoming a serious public health problem, owing the fact that dogs are the main source infection disease for human on domestic cycle. The closeness to dogs has been referenced as an important disease risk factor. This illness is endemic in several regions from Brazil, including the Paraiba state. In the period of December 2011 to February 2012, in Campina Grande, Paraiba, was conducted a seroepidemiological survey to Leishmania spp. in dogs, through serology study and research from the DNA of the parasite by the molecular biology. This study had a focus on the geographical distribution, correlating the socioeconomic and risk factors. From the 391 studied dogs, 33% showed a positive result to antibodies of Leishmania spp. by IFAT test, 4.34% by ELISA and 2% by PCR with detection of the parasite DNA in the animal blood. There was significant statistical difference to contactants (P = 0.02) and (OR = 4.1). The IFAT with L. major antigen, proved to be a proper confirm test that could be used as counterproof to ELISA test, which presented 39.4% of sensitivity. The combination of these two tests and its co-positivity was only 52%, which required another confirmatory test. However, for the negativity confirmation of IFAT, the ELISA test was considered reliable, with a 96.7% index. The use of PCR with total blood, showed low agreement and sensitivity with IFAT test, therefore not indicated as primary test, however efficient as counterproof. This research shown that CVL has adapted to urban areas, thus as endemic form and it concludes that a variety of diagnostic tests improves the detection of positive animals, becoming an excellent aspect to CVL control in certain areas, besides preventing euthanasia of false positives dogs / Mestre

In this thesis connections between messages on the public wall of the Russian social network Vkontakte are analysed and classified. A total of 1818 messages from three different Vkontakte groups were collected and analysed according to a new framework based on Halliday and Hasan’s (1976) research into cohesion and Simmons’s (1981) adaptation of their classification for Russian. The two categories of textuality, cohesion and coherence, describe the linguistic connections between messages. The main aim was to find out how far the traditional categories of cohesion are applicable to an online social network including written text as well as multimedia-files. In addition to linguistic cohesion the pragmatic and topic coherence between Vkontakte messages was also analysed. The analysis of pragmatic coherence classifies the messages with acts according to their pragmatic function in relation to surrounding messages. Topic coherence analyses the content of the messages, describes where a topic begins, changes or is abandoned. Linguistic cohesion, topic coherence and pragmatic coherence enable three different types of connections between messages and these together form a coherent communication on the message wall. The cohesion devices identified by Halliday and Hasan and Simmons were found to occur in these texts, but additional devices were also identified: these are multimodal, graphical and grammatical cohesion.

As an output of the HERA Travelling Texts project, created with the aim of uncovering the realities of women’s literary culture on the fringes of Europe during the long nineteenth century, this study was conceptualised to find out more about the networks of women writers in Spain around 1900, using the digitised corpuses of contemporaneous periodicals as the primary source material. Each chapter of the study centres on a particular periodical, which is used as the starting point for the community of writers and readers, both real and imagined. This thesis looks at the realities of the literary culture for creative women in the late nineteenth century-early twentieth century, exploring the strategies used by women (and men) to support each other in their literary endeavours, how they took inspiration and courage from each other, how they promoted their own names, and how they were received by wider society. The study will also focus on the transnational nature of this literary culture, looking at how women of different nations influenced each other’s work, with a view to understanding more about how cultural change takes place. Finally, this thesis hopes to persuade the reader that the periodical is a rich and under-utilised resource for discovering more about the lives of women writers and their network of relationships.

The objectives of this thesis were: (1) to develop a mass balance partitioning model of the natural uranium-238 series comprising radium-226, lead-210 and polonium-210 and (2) to apply the model to estimate the source and fate of these radionuclides in freshwater lakes and streams. Samples were collected from Ottawa River watershed tributaries and measured for lead-210 and polonium-210 content to determine the water concentrations that were input to the model. The radium-226 partitioning model was developed by reconstructing and analyzing Quantitative Water, Air, Sediment Interaction (QWASI) models of lead for Lake Ontario and Hamilton Harbour and selecting parameters for an updated QWASI model of lead for a Lake Ontario basin. This study gave insight about model basis definition, and partition coefficient and sediment particle constraint. The radium-226 series model was formulated by connecting separate QWASI modules for radium-226, lead-210 and polonium-210 with decay and ingrowth terms. The radium-226 model was applied to studies of Crystal Lake, Wisconsin; Bickford Pond, Massachusetts; and Clinton River, Michigan, using parameters reported in these and other studies. Model error was evident in the applications to Crystal Lake due to underlying lake heterogeneity, to Bickford Pond due to unidentified sources of lead-210 from sediment diffusion or watershed runoff, and to Clinton River from watershed runoff. The model was applied to seven Laurentian Shield lakes in the Ottawa River watershed using the sample measurements as the basis for water concentration inputs. The application showed that hydrologic flushing rate may be a factor in the proportion of watershed atmospheric deposition and overall Pb-210 input to the water. Laurentian Shield Lakes with the lowest hydrologic flushing rates (<3 a-1) had proportions of Pb-210 losses to sediment greater than 85%. In another application to Judge Sissons Lake, Nunavut, the model indicated that the watershed was the source of about 85% of Pb-210 and 98% of Po-210 input to the water, and that a significant geologic component of Pb-210 input to the lake was likely. The model indicated that most of the Pb-210 in Judge Sissons Lake was lost to outflow, and that most of the Po-210 was lost to sediment. The model showed that sedimentation is a better proxy measurement for atmospheric deposition of Pb-210 to the Laurentian lakes than originally estimated. The model also showed that watershed contributions to Judge Sissons Lake could explain the observed background concentrations of Pb-210 and Po-210.

La thèse explore les œuvres de Blaise Cendrars, de Victor Segalen et d’Albert Londres sous l’angle de « l’éclat du voyage » et se propose d’analyser les effets produits par la présence du voyage sur un plan diégétique, métadiégétique et stylistique. Chez ces trois auteurs, la notion de voyage dépasse en effet sa vocation thématique pour se faire véritable matière à travailler le langage, le texte et atteindre la sphère de la littérarité en exerçant sur le texte une menace d’éclatement. Le texte affecté par le voyage, loin d’être mis en péril, s’inscrit ainsi dans une modernité littéraire : en prenant le risque, par le détour du voyage, d’une écriture déformant, re-formant, re-définissant la littérature, les trois œuvres examinées illuminent quelques chemins de traverse dans lesquels s’engagent œuvres et critiques contemporaines. Cette étude interroge les premiers écrits de Cendrars (1912-1938) en explorant par quelles voies la présence conjointe du motif du voyage et de l’éclatement conduit à la création d’une représentation fractale du monde. La mise en évidence de trajectoires chaotiques des personnages cendrarsiens au cœur d’un monde ontologiquement fracturé permet l’édification textuelle d’une « anarchitecture » poétique et moderne. L’examen du cycle polynésien de Segalen met en évidence la présence du voyage comme le résultat d’un écart désirant, véritable menace de déchirure entre l’ici et l’ailleurs, soi et l’autre, soi et soi. Cet écart aboutit, à travers une présence textuelle, à la formation d’une poétique littéraire de la diffraction, poussant ainsi l’œuvre aux limites d’un hors-littérature. Enfin, à travers l’étude des reportages d’Albert Londres, la thèse montre comment l’écriture du voyage trouve un regain de force par le détour du reportage.

Introdução: O uso do crack constitui-se um dos maiores problemas de saúde pública na atua-lidade. O crack apresenta-se como uma nova forma de uso da cocaína, com padrão de uso cada vez mais intenso e compulsivo, ocasionando inúmeras intercorrências e implicações sociais e a saúde, levando o usuário a busca de tratamento. Objetivo: Conhecer a trajetória de tratamento do usuário de Crack em serviço ambulatorial de Atenção Psicossocial – CAPSAD III, através das narrativas sobre o consumo e busca por serviço especializado na rede pública de saúde. Método: Estudo qualitativo de uma amostra intencional de doze usuários de crack, sendo oito homens e quatro mulheres, em tratamento no CAPS ad III no município de João Pessoa/PB. Os dados foram explorados utilizando-se a técnica de análise de conteúdo. Instrumentos: Foi uti-lizada como instrumento de investigação, entrevista semiestruturada individual para a coleta dos dados sociodemográficos e das narrativas sobre o uso do crack e busca por tratamento. Foram aplicados o Questionário da Trajetória do Usuário de Crack/QTTUC e a Escala de Re-caída para usuários de crack – ERUC, porém os dados serão analisados e publicados em artigos posteriormente. Resultados: Os achados apontam dificuldades de acesso aos serviços especi-alizados, ocorrendo mais de uma tentativa para conseguir tratamento na rede pública de saúde e observa-se que os serviços da atenção básica e rede hospitalar, ainda não se encontram pre-parados para atendimento as demandas oriundas dos usuários de crack. Além da relevância do tratamento ambulatorial, evidencia-se a necessidade de serviços da assistência social para reta-guarda aos usuários em situação de extrema vulnerabilidade social. Conclusão: Os resultados sugerem a implementação de programas que possam facilitar o acesso de usuários de crack aos serviços do Sistema único de Saúde- SUS, qua / Background: Today, crack addiction is one of the major public health issues. Crack is as a new way of cocaine use, with intense and compulsive brains and body effects, resulting in a huge social complications, as well as health implications, leading to seek treatment. Aims: Under-stand the trajectory of crack addicted while in treatment at clinic of Psychosocial Care – CAPS AD III, through narratives about consumption and seeking for specialized doctors from public 8 health system care. Method: Qualitative study; convenience sample of 12 crack addicted, 8 men and 4 women, undergoing treatment at CAPS ad in the city of João Pessoa / PB. We review the data through content analysis technique. Instruments: We made a semi-structured inter-view for each subject for demographic data collection, as well as we collected narratives about the consumption of crack and treatment. We applied questionnaire of crack User trajec-tory/QTTUC and Crack Use Relapse Scale (CURS), but the data will be analyzed and published later. Results: These findings indicate that accessing specialized services is a tough pathway. Usually, the health public consumer must go there more than one time to be attend. In addition, the public health system still have not enough structure to attend demands from crack users. Be-sides the relevance of clinic treatment, it is highlighted that social services is essential for users supporting. Conclusion: The results suggest that is mandatory develop and execute programs that would facilitate crack users access to the Public Health System. To sum up, increase quality actions at different levels of health care and improve the relapse prevention process is central to crack users avoid relapses while in treatment.

abstract: The mechanical behavior of Pb-free solder alloys is important, since they must maintain mechanical integrity under thermomechanical fatigue, creep, and mechanical shock conditions. Mechanical shock, in particular, has become an increasing concern in the electronics industry, since electronic packages can be subjected to mechanical shock by mishandling during manufacture or by accidental dropping. In this study, the mechanical shock behavior of Sn and Sn-Ag-Cu alloys was systematically analyzed over the strain rate range 10-3 - 30 s-1 in bulk samples, and over 10-3 - 12 s-1 on the single solder joint level. More importantly, the influences of solder microstructure and intermetallic compounds (IMC) on mechanical shock resistance were quantified. A thorough microstructural characterization of Sn-rich alloys was conducted using synchrotron x-ray computed tomography. The three-dimensional morphology and distribution of contiguous phases and precipitates was analyzed. A multiscale approach was utilized to characterize Sn-rich phases on the microscale with x-ray tomography and focused ion beam tomography to characterize nanoscale precipitates. A high strain rate servohydraulic test system was developed in conjunction with a modified tensile specimen geometry and a high speed camera for quantifying deformation. The effect of microstructure and applied strain rate on the local strain and strain rate distributions were quantified using digital image correlation. Necking behavior was analyzed using a novel mirror fixture, and the triaxial stresses associated with necking were corrected using a self-consistent method to obtain the true stress-true strain constitutive behavior. Fracture mechanisms were quantified as a function of strain rate. Finally, the relationship between solder microstructure and intermetallic compound layer thickness with the mechanical shock resistance of Sn-3.8Ag-0.7Cu solder joints was characterized. It was found that at low strain rates the dynamic solder joint strength was controlled by the solder microstructure, while at high strain rates it was controlled by the IMC layer. The influences of solder microstructure and IMC layer thickness were then isolated using extended reflow or isothermal aging treatments. It was found that at large IMC layer thicknesses the trend described above does not hold true. The fracture mechanisms associated with the dynamic solder joint strength regimes were analyzed. / Dissertation/Thesis / Ph.D. Materials Science and Engineering 2012

A pesquisa se insere no campo dos estudos relacionados às instituições escolares, considerando a importância atribuída a esse tipo de instituição cuja característica específica é formação de professores, dois eixos que consideramos importantes no nosso estudo. Tivemos como objetivo investigar os determinantes sociopolíticos e educacionais que compuseram a criação da Escola Normal Estadual para Campina Grande (1955-1960). O recorte temporal definido, entre 1955 e 1960, diz respeito ao período compreendido entre um momento político nacional e local fontes de grandes mudanças sócio educacionais e o ano de criação da escola. Para nortear a construção do objeto de estudo, elegemos as categorias temáticas criação da instituição, feminização e formação de professores, e nos fundamentamos nos referenciais teóricos de Saviani (2007); Tanuri (2000); Nosella e Buffa (2013); Vicentini e Lugli (2009); Almeida (1998/2004); Chamon (2005) entre outros. A pesquisa de cunho documental utilizou fontes históricas como: jornais, mensagens do governador Pedro Gondim, fichas de matrícula das alunas pioneiras, fotos, regimento interno do colégio, dentre outros documentos. Enfatizamos o descompasso de criação da escola em comparação com a instituição de formação docente pessoense e outras escolas formativas pertencentes ao domínio particular, de modo que a ENECG é a primeira instituição pública para formação de professoras na cidade de Campina Grande e defendemos o argumento que a instituição foi formada, essencialmente, para as moças da sociedade campinense, a chamada “juventude feminina”. Na consulta e análise empreendida nos periódicos locais e estaduais, com destaque para o jornal diário da Borborema, percebemos que a criação da escola foi uma necessidade de aperfeiçoar as professoras que atuariam no ensino primário, considerado na cidade enquanto insuficiente e precário. A partir das reflexões desenvolvidas ao longo do trabalho, concluímos que a criação da Escola Normal Estadual de Campina Grande constituiu-se enquanto manobra política, uma vez que a promessa e cumprimento da criação da escola corroboraram a necessidade de ampliação educacional nacional e local, junta-se a esse movimento, a elite letrada campinense. Por meio do recurso da imprensa, foram noticiadas as debilidades do ensino primário, com ênfase na má formação das professoras campinenses compondo, assim, o cenário de promessa anunciada em 1958 e com a criação da instituição em 1960. No que diz respeito ao seu funcionamento em prédio próprio, só ocorreu dez anos mais tarde, em 1970. / The dissertation "In The Benefit of the Formation of Female Youth"- Escola Normal Estadual of Campina Grande (1955-1960) it is about the creation of a school institution for teacher formation in the 1960s, located in a city in Paraíba. The study is part of the studies related to school institutions, considering the importance attributed to this type of institution whose specific characteristic is teacher training, two centerlines that we consider important in our study. We aimed to investigate the socio-political and educational determinants that made the creation of the Escola Normal Estadual to Campina Grande (1955-1960). The definite temporal cut between 1955 and 1960 refers to the period between a national and local political moment, the source of great social-educational changes, and the year of creation of the school. To guide the construction of the study object, we chose thematic categoriesthe creation of the institution, feminization and teacher formation, and we base ourselves on the theoretical references of Saviani (2007); Tanuri (2000); Nosella and Buffa (2013); Vicentini and Lugli (2009); Almeida (1998/2004); Chamon (2005) and others. The documentary research used historical sources such as newspapers, messages from the governor Pedro Gondim, registration forms of the pioneer students, photos, internal regiment of the college, among other documents. We emphasize the mismatch of creation of the school in comparison with the institution of teacher formation in the state capital and other training schools belonging to the private domain, such as ENECG is the first public institution for teacher formation in the city of Campina Grande and we defend the argument that institution was formed essentially for the girls of the local society, the so-called "female youth.". In the consultation and analysis undertaken in local and state journals, highlighting the Diário da Borborema daily newspaper, we realized that the creation of the school was a necessity to improve the teachers who would act in primary education, considered in the city as insufficient and precarious. From the reflections developed throughout the work, we conclude that the creation of the Escola Normal Estadual of Campina Grande constituted itself as a political maneuver, since the promise and fulfillment of the school's creation corroborated the need for national and local educational expansion together to this movement the literate elite residents of Campina Grande. Through the news, the weaknesses of primary educationwerereported, with an emphasis on the poor formation of local teachers, thus, composing the scenario of promise announced in 1958 with the creation of the institution in 1960. With regard to its functioning in an own building, only occurred ten years later, in 1970.

This thesis investigates the dynamics, motivations and external factors influencing the migration trajectories of 22 young, well-qualified Polish and Spanish migrants in the South of England. The study is among the first ones researching the current movement of people from Spain to the UK in the aftermath of the global financial crisis of 2007/08, and comparing it to post-EU-accession migration from Eastern Europe. The methodology involves semi-structured, autobiographical interviews focusing on participants’ migration experiences, with a particular focus on their professional ambitions in the UK labour market. The findings of the study demonstrate how both groups interpret emigration as an act of establishing a certain form of normality, be it social, economic or individual. Overall, however, the narratives reveal differences that run along the lines of nationality. In the Polish narratives in particular, a strong focus on the immediate present becomes evident. The present life in the UK, no matter how challenging, is almost always compared to a past in Poland that is retrospectively defined as ‘abnormal’. Participants create a discourse of escape that is then used to make sense of an often ‘not ideal’ present in which participants, despite being university educated, spend prolonged periods of time in low-level jobs. The Spanish narratives, on the other hand, tend to be highly politicised and participants display a strong sense of individualisation and political anger. Most narratives are characterised by an ‘ideology of progress’. Spain is referred to as a space of personal and professional stagnation, while time spent in the UK is seen as a conscious investment in human capital such as English skills. The aim of this investment is the establishment of a certain socio-economic status in the future, and menial jobs in the UK are acceptable as long as participants work towards that goal. In summary, the thesis analyses how both groups react to social and economic changes in times of a global economic crisis, and describes how participants tend to meet unknown circumstances with a known set of behavioural dispositions.
