Full textDoctor of Philosophy
The mechanism of material failure due to repeated cycles of large deformations is denoted as Low-Cycle Fatigue (LCF); this failure mechanism can occur in steel structures subjected to loading conditions such as those induced by earthquakes. Mathematical expressions that evaluate the material deterioration due to LCF are often used to predict the instant and location of fracture initiation in small-scale and large-scale tests. An experimental program was conducted for the study of fracture associated with LCF. A total of 60 specimens were fabricated with material extracted from the flat and corner regions of two rectangular steel tubes; the applied loads elongated and/or twisted the specimens until they ruptured. Computational simulations of these tests were conducted to obtain key information at the location of the observed fracture initiation. This information was used to adjust five mathematical expressions suggested by previous researchers that could predict the same instant of fracture initiation observed in the experiments. The accuracy of the predictions from each of these mathematical expressions was evaluated. The accuracy of these mathematical expressions to predict fracture initiation in a large-scale test was also investigated. To this end, an experiment was conducted on a rectangular steel tube subjected to repeated cycles of deformation. A computational simulation of this test was also developed, and predictions of the instant and location of fracture initiation were compared with the experimental observations.

Full textMarriage and marital satisfaction are important aspects of human development, which have raised the interest of many researchers in Psychology, especially in the areas of Clinical Psychology and Psychological Assessment. The main objective of this study was to develop a new instrument for the evaluation of marital satisfaction, the Couple Drawing Test (CDT), as well as to establish possible graphic and dynamics indicators for that purpose. We intended to verify, through CDT, whether there were differences, concerning marital satisfaction, between individuals with and without children, and also between men and women in the city of Sao Paulo. An initial number of 201 subjects took part in the research, 100 men and 101 women, equally divided in groups of individuals with and without children. They had all been married for the first time, for a period of 1-10 years, without occurrence of pregnancy during research period, and possessed a minimum educational level of incomplete high school. Data was collected individually. The assessment instruments were: graphic material for the administration of the CDT; a Marital Satisfaction complementary assessment form (especially developed for this study); Marital Satisfaction Scale (MSS); Marital Adjustment Test adapted to Brazilian context (MAT-MARI); and voice recorder. After the evaluation of the MSSs and MAT-MARIs, 27 subjects were excluded from the sample analysis because they fell in a neutral range of the marital satisfaction indicators. The final sample had 174 subjects, half of each sex. The drawings were evaluated by seven judges who were psychologists with expertise in the evaluation of projective graphic techniques. The main results concerning the CDT were: reliability coefficients higher than 0,600 in the evaluation of the majority of judges in 28 out of the 38 proposed items; the items story impact and global evaluation impact showed appropriate validity for the evaluation of marital satisfaction; seven items were considered expected, with a >85% frequency on drawings; ten items were identified as indicators of marital dissatisfaction; a minimum number of indicators was established for the diagnosis of marital dissatisfaction. Concerning the main differences in marital satisfaction for men and women, with and without children, the findings were that 14 aspects significantly distinguished the answers of maritally satisfied and dissatisfied individuals (p_0,02) and significant differences were found between men and women with regard to the issues 6 considered important for the marital satisfaction. The conclusion was that the CDT and the complementary data obtained might assist professionals in their clinical work with families and couples, not only in the diagnosis of marital dissatisfaction, but also in the suggestion of preventive actions regarding the marriage welfare. Nevertheless, we emphasize the need of further studies on psychological evaluation and identification of elements concerning marital life in the course of family development, once the variables researched proved to be, over time, extremely dynamic and multifaceted.

The leather tanning of fish is a way of alleviating the damage caused by chromium salts to the environment. this work had as objective evaluate the process of tanning leather in the skins in corvina and pescada amarela from fishing made in the northern region of Brasil and tilápia origin of fish farming. The species caught in the fishing of the region present the potential for use in the tanning because they are large, which allows you to add value to the final product. The skins were to the same tanning process not differing in any of its stages. to determine the efficiency of the process, the skins of corvina, pescada amarela and tilapia were submitted to the resistence test the traction, stretching and progressive tear in the longitudinal and transverse directions of the body of the fish and the physical-chemical analysis. the resistance tests the traction and stretching were satisfactory for manufacturing of products and clothing. However, suggests improve the grease of the tanning process.
O curtimento vegetal de couro de peixes é uma forma de amenizar os danos causados pelos sais de cromo ao ambiente. Este trabalho teve como objetivo avaliar o processo de curtimento nas peles de corvina e pescada amarela oriundas da pesca realizadas na região norte e tilápia oriunda de piscicultura do estado do Paraná. As peles foram submetidas ao mesmo processo de curtimento vegetal não diferindo em nenhuma das suas etapas. Para determinar a eficiência do processo, as peles de corvina, pescada amarela e tilápia foram submetidas à análise físico-química, ao teste de resistência à tração, alongamento e rasgamento progressivo no sentido longitudinal e transversal do corpo do peixe. Foi realizada a analise histológica dos couros, para se analisar a estrutura das fibras. Os testes de resistência à tração e alongamento foram satisfatórios, comprovando que as peles das espécies capturadas na pesca da região norte do Brasil apresentam potencial para utilização no curtimento, apresentando qualidade apropriada para confecção de produto, vestuário e calçado. Entretanto, sugere-se aprimorar a etapa de engraxe do processo de curtimento.

Full textThe multi-material forging is a forming process allowing, simultaneously, the welding and shaping of multi-material parts with the right material at the right place. The purpose of the presented work is to identify the necessary conditions to obtain a metallurgical bond during forming between two different grades of steel. First, the state of the art allowed the identification of the physical phenomena occurring during multi-material forging and the determination of the key parameters of the bonding which are the contact pressure and the surface expansion at the both sides of the interface. The mechanisms to establish metallurgical bond by forging are based on the breaking and the dispersion of the oxide layer at the interface then the extrusion of the soft material through the voids generated between the oxide fragments. Second, the characterization methodology of this work is presented. It consists of three “simple” forming tests leading to different interface conditions (contact pressure and surface expansion). The first simulations allow the design of the experimental plan for each test. The comparison between simulations and experiments allows the identification of physical parameters of the simulation. Then, the contact pressure and the surface expansion of the identified simulations are used to analyze the metallographic structure and the bonding at the interface.The developed work confirms the major effect of the contact pressure and the surface expansion on the establishment of a metallurgical bond during multi-material forming. The size and the shape of the oxide particles seem to depend on the thermomechanical path at the interface

A indústria do couro consome grande quantidade de água no processamento das peles, alcançando cerca de 30 a 80 m3 por tonelada de peles processadas. Os efluentes líquidos são caracterizados pela alta salinidade, alto conteúdo de matéria orgânica (DQO, DBO, COT, COD), nitrogênio orgânico e amônia. Além disso, estão presentes corantes, surfactantes, sulfetos orgânicos e inorgânicos, cromo, fenóis, surfactantes não-iônicos e pesticidas. As técnicas tradicionais para tratar efluentes de curtume são eficientes, mas predominantemente transferem parcialmente estes poluentes da fase líquida para a fase sólida, gerando o problema de disposição de resíduo sólido altamente tóxico. Novos métodos têm sido desenvolvidos para tratar efluentes industriais com o objetivo de produzir efluente tratado de alta qualidade e redução da geração do volume de lodo químico ou biológico. Desde a década de 70 os Processos de Oxidação Avançados (POAs) para tratar água, efluentes industriais e poluição atmosférica têm sido estudados. Estes processos envolvem a geração de radicais hidroxil como intermediários reativos, os quais têm um alto potencial de oxidação, capazes de decompor não-seletivamente compostos orgânicos, inorgânicos e metálicos, formando produtos menos nocivos. Neste trabalho foi estudado o tratamento de efluentes de curtumes utilizando Processos Avançados de Oxidação, utilizando efluentes sintéticos e efluentes reais de curtumes. A redução fotocatalítica simultânea do Cr(VI) e degradação do corante preto Luranzol S Kong foi estudada num reator batelada utilizando dióxido de titânico como catalisador. Os resultados mostraram que é possível eliminar cor e reduzir Cr(VI) simultaneamente, sendo que o corante atua como um doador de elétrons para a redução do Cr(VI). A cinética de descolorização obedeceu um modelo do tipo Langmuir-Hinshelwood e a velocidade da reação é mais rápida em pH ácido do que em pH neutro. Foram avaliados os processos de ozonização (O3), degradação fotocatalítica (TiO2/UV), degradação fotoquímica (H2O2/UV) e o processo Fenton, para tratar o efluente real da indústria do couro. A eficiência destes processos foi avaliada através de caracterização convencional (DQO, DOC, TOC, DBO, nitrato, amônia, sulfato, cloreto), toxicidade, e análises de substâncias específicas por cromatografia gasosa - espectrometria de massa e cromatografia líquida - espectrometria de massa. Os efeitos do pH, da concentração de H2O2 e da concentração de Fe2+ foram estudados. A oxidação dos poluentes orgânicos contidos no efluente de curtume, aplicando diferentes técnicas de POA, é mais ou menos efetiva de acordo com o potencial de oxidação do reagente utilizado e ao ajuste das condições do processo. Todos as processos de tratamento aplicados (TiO2/UV, O3, Fenton e H2O2/UV) resultaram em oxidação parcial e mineralização acompanhados da diminuição da DBO5. Apesar da degradação parcial, a toxicidade permaneceu constante. As análises de substâncias específicas aplicando GC- ou LC-MS acusaram a presença de fenol, benzotiazol, nonilfenoletoxilato e polietilenoglicol no efluente, que foram completamente degradados durante as diferentes etapas de POAs, conforme as análises GC-MS e LC-MS. Apesar da destruição de poluentes pelos diferentes tratamentos oxidativos, não foi observado aumento da biodegradabilidade, uma vez que foram encontrados compostos oxidados polares, com estrutura poliéter, gerados pelos tratamentos, e estes compostos são de difícil degradação ou eliminação nas estações de tratamento de efluentes.

Full textThis dissertation conducts to a comparative perspective among the reading of the Mozambican authors novels Mia Couto A river called time, a house called land and before the world was born. From the spatial fluctuations of the central characters Marianinho and Mwanito, who move between the countryside and the city, holds up a reading of such spaces considering the interplay between Mia Coutos fiction and the Mozambican reality. For this study, we rely on several authors such as José Luis gourd, which opened the horizon on the socio-historical processes that involve current Mozambican reality, Mikhail Bakhtin, Georg Lukacs, Walter Benjamin and Theodor Adorno, who based us critically and theoretically and Antonio Candido, who guided the reflections on the social aspects that involve literature. The study also discusses how young Marianinho and Mwanito may represent the formation of a new Mozambican identity, permeated by tensions between colonizer and colonized, tradition and modernity, rural and urban, among other dichotomous pairs.

Full textThe present study is based on our readings on Mia Couto and deals specifically with the relations between memory and identities in Um rio chamado tempo, uma casa chamada terra, from the perspective of its contribution to the building of a \"Mozambicanship\". Amílcar Cabral and Franz Fanon, two key authors on the issue of African revolution (mainly in the countries that attained their independence through a armed liberation struggle, which is the case of Mozambique), were among my most important theoretical references about Africa. On the questions of migration, diasporas and identities I supported my work in post-modern authors, in particular in Stuart Hall and Terry Eagleton. My work focus also on the relations between postcolonialism and postindependence, postmodernism and postmodernity, oral tradition and novel. Finally, I try to elaborate on the place of literature and the role of the narrator in a romance whose action occurs in a field of conflicts as those between urban and rural environment, tradition and modernity, past and present.

Full textAs an influential politician and a successful industrialist, and having written a number of books, General José Vieira Couto de Magalhães (1837-1998) was one of the few men of his time leaving a register with precious information about everyday life concerning medicine and body care aiming to the restoring of health. His personal notes correspond to two different moments of his life. Firstly, to the beginning of the 1880s, when he was affected by digestion problems. In this phase, Couto demonstrated more interest in self-medication based on the reading of medical compendiums. Afterwards, between 1887 and 1890, the General kept a notebook in which he wrote brief reference notes on the syphilis diagnosis he was given at home by two doctors. At this time he was 52 and used to be the president of the Province of São Paulo. Incurable and closely related to moral issues, syphilis was then associated with prostitution, being considered one of the causes of degeneration in offspring. At the third stage of the disease, the General was quite impaired and thus had appointments with the best physicians in Brazil as well as in France, where he travelled to twice during the treatment. In an attempt to understand the implications of such diagnosis for a man in a high social position, this study faces crucial issues for that time period. One of them concerns the usually difficult and much less prestigious life of medical doctors who were for a long time analyzed from a predominantly foucaultian perspective as having a disciplinary power over society. In order to work with Magalhãess life story and notes and above all with the silences inside his writings I try to compare the information in his journals with other from periodicals , theses and medical books from that historical period.

Full textThis paper presents an analysis of the novel A varanda do frangipani, from the Mozambican writer Mia Couto, in order to illuminate the reinventions done by he author of the sacred aspects linked to the traditional beliefs of Mozambique. Appropriating and subverting the Standard classic detective novel the symbol of European rationality exaltation the author reinvents within literary sacred animals, rituals of initiation and divination, spirits living among us, as well as divine trees, and shows the reader a different world view and a form of existence from the Eurocentric one. Therefore, there is enlightenment of cultural and social issues from the country where Mia Couto speeks, where the attempt to cultural imposition was operated by years of wars and domination. We based this research, on authors such as Mircea Eliade, Carlos Serrano, Jose Luis gourd, Omar Ribeiro Thomaz, and others, to obtaining the necessary theoretical consistency about the concept of sacred and socio-cultural issues related to Mozambique and other African countries, we rely on authors as Tzvetan Todorov and Ernest Mandel also, to establish the structural pattern and a little bit of the ideology linked to classic detective novel and thus verify the reinvention so on Mozambican soil.

Full textThroughout the readings of the novels of the Mozambican author Mia Couto is possible to observe that, systematically, the writer proposes the reader to approach and dialogue between the subjective world of the characters within the text and history of Mozambique, starring actors such fictional clippings in chronological in which past and present are constantly in dialogue. Thus, manifest in his prose an intrinsic relationship between literary productions and, therefore, the specificities of the field of fiction and the author\'s commitment to the historical reality of his country. Through these characters in his stories and novels, history of Mozambique is presented and the author builds a critical perspective of the country outlining a concrete social reality and manifests strongly in the space where the characters live and circulate. The Mozambican scenario described thus in his novels and stories, the reader approaches the historical reality and also the country\'s social, gathering material dynamics of life in Mozambique - with their specific cultural and local traditions - as well as a reflection of their own social role of literature.

The theme oppression permitted to study the relationships of power and submission between the characters of the two works. This thematic been present throughout the literary-critical analysis reasons, philosophically, the actions of the characters, often reflected the historical situation experienced by the authors. Semantically varied and controversy, the word oppression is provided in this approach, the possibility of an interpretation of a study of socio-cultural moment in which the works were written, following the philosophical line developed by the German thinker Sigmund Freud, in refers to the interpretation of the double. The research was theoretical served as Todorov, Caillois and Bessière to the approach of gender in this fantastic two works. Because of having to be searched throughout the literature of the two authors, felt the need to quote other works, which helped to establish a dialogue between the narratives and other selected works of the two writers. By studying the narratives of the authors, it was thought it was a necessary insertion in the recent history of two countries whose survey is inserted in the annexes. Why not forget the socio-cultural context of the preparation of the two texts, is that the survey reflects the historical circumstances at the time of their creation, while, however, understand that the literature that goes beyond simple mirror of reality, because the literary work In addition to dialogue with the world around them, and argue with times and places other than the reality. The choice of this theme is also gave the theoretical question of order, hence the choice of the body, submitted for study

Full textLiterature assumes singular contours in the surround of the hegemonic countries. Brazil and Africa are territories marked by complex tension between genuine elements and elements imposed by colonization. Our attempt is to bring together these bordering experiences in this thesis of Comparative Literature in which we reflect on the sacred elements as a significant source to help build identity. We present a comparative reading of Mia Couto and Manuel de Barros, as examples of Brazilian and African culture. The sacred, seen as a dimension of existence, different from the profane component (although present in it), is part of the aesthetic and political project of both authors, being important to establish the identity of these cultures, as well as to project a new human being and a new way of knowing and learning in the XXI century. Either visible or disguised, the sacred is part of both the traditional and the modern culture, being present in works of literature for adults or children. Through its manifestation, both in poetry and prose, it is possible to spot similar roots and identity features in the two cultures and literatures that compose a macrosystem, in which none of them can be considered a paradigm. Portuguese language is the means with which Brazil and Mozambique strengthen and unite their experiences. It is our aim, in our critical thinking, to find, in the new ways of experiencing multiple border realities, a tangling of communities and their cultures. We would like to create bonds of solidarity capable of expanding across national borders as to reach the \"supranational\". The transcendent elements shown to the reader in the imaginary path nurture his actual living experience, making for possible changes in the future. We believe literature to be the ground on which culture thrives, empowering the human being, triggering understanding and transformation.

Full textMachining holds an important place in the industry, this is one the most common process. As thus, mastering the milling process, especially during a finishing operation, has become a major issue in the insdustrial sector. Understanding the physical phenomena present in a finishing machining is an important factor for the optimization of a manufacturing process by removing material.In order to determine the most important factors during a finishing machining, in particular during a profile milling, a new experimental methodology will be developed. This work will focus on three main activities :- The introduction of instrumentation capable of collecting an image cutting forces. This experimental device must be equipped with sensors and an acquisition channel to acquire the components of the forces in the x and y directions.- The development of a new device going through a stage qualification in which a series of tests will establish the capability of experimental device.- This experimental study is accompanied by a series of tests to define the most important parameters in a finishing profile milling

Full textIn this PhD thesis, two novels are comparatively analyzed, Sleepwalking land by Mia Couto and Mother, Maternal Sea by Boaventura Cardoso, from Mozambican and Angolan literatures, respectively. The approach focuses on the space, considered as the central category to the global sense of the novels, thereby establishing relations between internal and external elements of the texts in regard to the theme of the nation. The main spaces of the analysis are the road, the land, and the sea, with emphasis on the vehicles, bus and train, and their transit problems, which raise the hypothesis of being often metaphorically related to the characteristics of Angola and Mozambique in the post-Independence period. This is, therefore, a comparative study based on a theoretical and critical framework of a different set of authors in order to establish a dialog among literature, geography, history, and religion. Among the results of the analysis is the prevalence of dualities, counterpoints and ambivalences of several motifs related to the space, such as immobility/movement, will/destiny, life/death, light/shadow, tradition/modernity, reality/imagination, religion/politics. In some cases, the ambivalence involves both a negative and a positive side, e.g., after the chaos, it is possible to restore the order, the harmony. Thus, as the road projects the future, making its way from the land to the sea with its motherly attributes, it is possible to understand the open-ended denouements of the novels as a form of hope, suggesting the possibility of a rebirth of individuals and of the nation.

Full textThe aim of the research is to analyse the choice for undergoing a vasectomy procedure considering theoretical principles in intersubjective psychoanalysis and gender studies. From the medical point of view, the vasectomy is a contraceptive surgical procedure of irreversible character underwent by men. The choice for this subject is associated with the growing number of vasectomies carried out in Brazil and with the fact that it is a procedure that concerns the couple as a whole at the interface between conjugality and parenthood, an issue that deserves more study. The present study holds as elements intrinsic to this choice: changes in the society related to gender differences in the family, work environment and social relations, along with the shift in marital bonds. As for the clinical and qualitative methodology, semi-structured interviews have been carried out with two couples between 31-37 years old (the period of major female fertility) who intended to undergo the vasectomy procedure. The interviews would address subjects related to the process of opting for the surgery, the dynamics of the couple and the family history combined with social, cultural and generation issues. Due to the complexity of the subject, the present dissertation is divided into chapters on the decisions the couple has to make, the problematic of gender and on public policies concerning contraceptive methods. It was concluded that the analysed couples decision for vasectomy is related to birth control connected with socio-economic issues. It is also related to different fantasies regarding the establishment of bonds: the hope for a more pleasant sexual life not linked to reproduction, and the management of reproduction associated with the control and maintenance of the relationship. Also, the choice for vasectomy was the result of the current public policies that aim for contraceptive methods, in addition to gender issues. It could be verified in the interviewed couples that, although the vasectomy procedure takes place in the male body, the choice for this contraceptive method belongs in the marital sphere and, thus, it is inherent both in interactional aspects of such a sphere and in the marital bond

Full textGiven the European guidelines, which consist into producing 20% of the energy from renewable sources, the governments are obliged to invest in new types of production systems. An energy market survey will show the part of renewable energy in the energy consumption. After the hydroelectric systems, the wind turbines are the most common systems using renewable sources. The current objectives have led to consider the installation of offshore wind turbine. The specific limitations led the market players to develop new systems with adapted generators: direct drive permanent magnet generator. Model of the permanent magnet machines is described. First a conventional machine topology is presented, then other solutions will be studied with the objective of increasing the torque density. One of them is the concentrated winding machines where the end winding overlapping is avoided. On the other hand, use multiphase system becomes very interesting in order to increase system reliability and work in fault tolerant modes. The strategy that was adopted for the design of the generator to fit the best the specification is also discussed as well as the results of the tests. At the end, the wind turbine equipped with this alternator, has a power density at least 15% higher than the 2013’s available solutions

Full textThe object of our study are the novels Mãe, materno mar (2001) by the Angolan writer Boaventura Cardoso (1944-), and Um rio chamado tempo, uma casa chamada terra (2003) by the Mozambiquean writer Mia Couto (António Emílio Leite Couto [1955-]). The research focuses upon a comparative analysis of these novels by pointing to the strategies applied to temporal constructions into these narratives, as well as their capacity of reflecting and illuminating the conflict between modernity versus tradition in the social experience where these works have been produced. And therefore, to discover how such strategies would reveal the peculiarities of the genre novel in its African version. In order to base the hypothesis of \"time\" as a key-element in our study, we elected some theoretical and interpretative resources from Norbert Elias, Paul Ricoeur, and Leda Martins; as well as general contributions from African and Africanist literary criticism.

Full textFor each kind of production, the tool's wear can make important consequences on her. Wear is a common subject through the industry, and this phenomenon mastering always makes an advancement for entreprises who are interested in. This work deals with the wear phenomenon decomposition between different processable studies in order to permit a study and a global comprehension of this complex phenomenon. That's why we decided to separate the general cutting hedge general wear in wood industry second transformation between two parts : corrosion and abrasion. According to the wood material and his cutting specificities, the corrosion study was made by an electrochemistry test adaptation whereas the abrasion one needed the creation of a specific testing stand : TEEMO. To complete this study, we carried out experiments on generated temperature during the machining process. Through all this project, the results validates the departure theories i. E. Corrosion and abrasion have interaction to generate the cutting hedge global wear. With the sights of this work, the chemical composition of the cutting material is a factor as important as the material mechanic properties against the wear

Full textIt was determined that regulatory elements of the atrial-specific expression of the promoter SMyHC3 are contained in a complex nuclear receptor response element (CNRRE). Cellular transactivation assays indicated certain nuclear receptors (NR) can bind in this region. From these trials, was observed the promoter activation by a nuclear receptor, COUP-TFII. It regulates many biological processes such as angiogenesis and atrial development. Deletion of CNRRE resulted in no activation of the promoter by COUP-TFII, indicating their connection in this region. We also verified that only the ligand binding domain of COUP-TFII is able to activate the promoter, suggesting interaction with other NRs to activate it. A proteomic analysis revealed that most of COUP-TFII partners relates to complexes of transcription regulators and the androgen receptor (AR) signaling pathway. Cell transactivation assays showed that together, COUP - TFII and AR, are able to increase promoter activation.

Full textIntermetallic compounds based on titanium aluminides are considered promising for structural applications in high temperatures. They presented mainly low density (3.2 to 4.2 g/cm3), high melting point (1400 to 1500 °C) and high mechanical strength between 600 and 950 °C. The study of diffusion between ?-TiAl and Fe-rich materials is important to observe phenomena and obtain relevant data joining these materials with steel - the most versatile metal alloy known. Components such as automotive turbochargers will benefit from the development and application of TiAl alloys, and represents an important aspect the junction between TiAl wheel and steel shaft component. The work was performed in three steps: obtaining ?-TiAl intermetallic single-phase; investigation of ?-TiAl/Fe diffusion couples; and investigation of ?-TiAl/Steel diffusion couples. Alloys with Ti50Al50 and Ti47Al53 compositions were made and characterized by optical microscopy, scanning electron microscopy and EDS microanalysis, X-rays diffraction and hardness tests. The ?-TiAl and ?2-Ti3Al phases were observed in several microstructures according to the chemical composition and the sample heat-treatment. The lattice parameters and volumetric fractions of ?-TiAl and ?2-Ti3Al phases was determined by X-ray diffraction by the Rietveld method. The average hardness found in TiAl samples was 272-340 HV500. The Ti47Al53 alloy heattreated at 1200 °C for 7 days showed ?-TiAl single-phase and it was chosen for diffusion couples investigations. Microstructural characterization, dilatometry tests, hardness tests, and chemical analysis was performed on a steel sample removed from the automotive turbocharger shaft. The ?-TiAl/Fe and ?-TiAl/Steel diffusion couples were made and heattreated at 800, 1000, 1200 °C for 24 hours and were microstructurally characterized by SEM/EDS. In couples made of Iron, lower heat-treatment temperatures allowed the highest attachment regions of the material and smaller amounts of cracks was found, probably due to lower internal stress during cooling. In the couples made of steel, it was observed the formation of Ti-rich carbides that worked as diffusion barrier, reducing considerably the binding regions compared with Iron couples. In all diffusion couples samples, several reaction regions on the diffusion interface were observed and through the literature it was suggested the probable phases present in each region.

Full textAs a gesture of resistance to colonialism and in relation to the asymmetries imposed by hegemonic power centers, facing the political power of the European metropolis peripheral writers played a significant role in the struggle for the liberation of their countries. Throughout this period of anti-colonialist struggle, booming literary systems also resulted in strengthening the relations between their authors whose ideas circulated in the European metropolis as well as in the colonized territories. Concerning the African territories colonized by Portugal, if they conquered their independence in 1975 after more than a decade of armed struggle, the same did not happen to the Antillean islands under French domination- with the exception of Haiti, which conquered its independence in the nineteenth century. Thus, considering this historical difference, we highlight in this work written reflections of the writer Patrick Chamoiseau from Martinique and Mia Couto from Mozambique whose performances as intellectuals in the global arena information stands out in searching answers that could be able to discuss the political and cultural tensions that are characteristic of our contemporary world . Thereby, through comparative analysis and dialectical approach, our aim in this work is to analyze two essays: Lintraitable beauté du monde adresse à Barack Obama (2009), co-authored by Patrick Chamoiseau and Édouard Glissant; and E se Obama fosse africano (2009a), by Mia Couto. At doing so, we also make an effort to foreground strategies to review Eurocentric epistemology and the marginal thoughts in the political global scene. In a second analytical deployment, this work attempts to identify and confront three guiding principles in the novels of the two writers Texaco (1993) by Patrick Chamoiseau and Jesusalém (2009b) by Mia Couto: the representations of memory, of the feminine and the space. We regard those representations as important elements of the field of the forces of political articulations aiming the construction of identity projects in Martinique and Mozambique in relation to the planetary system.

Full textThe main focus of this study is the observation of the benefits brought about by fish leather, specially when it comes to the textile and apparel market. Fish leather samples were compared to bovine leather mainly and to other kinds of leather. Fish leather shows stronger resistance, and it proved to be much stronger than bovine leather specifically, three times stronger. Fish leather is also the only leather to be obtained after the animal is slaughtered. In the specific case of the fish, everything that remains from the leftovers is used after the edible parts of the animal are set apart. Its skin becomes leather; its bones become fuel and coatings for automobiles. Therefore, there are plenty of usage options to be considered. Furthermore, such options are eco-friendly, not only because of the social and environmental reprocessing techniques involved, but also because they prevent the pollution of rivers and seas brought about by irresponsible disposal which may cause clogged drains, pollution, poisoning, and all sorts of contamination of the water

Full textThe studies that register the Amazon in the transition from the 19th to the 20th century represent an expressive linguistic and anthropological material due to the intention of register the habits and values of the indigenous people by the literary construction in Língua Geral (General Language) or Nheengatu, that no longer was the most spoken language in the period. Loaded of memories, landscapes and scientific information, these texts have influenced the construction of a national literature, though the perspective of the literature of information, that corroborated the construction of Brazilian identity formation. This literature expands the universe of romantic ideals and contributes to the understanding of a contact process of various forces and cultures. Therefore, the intention of this documentary record through questions and comparisons about the course and presentification of memory, individual and collective, of indigenous societies, through the myths and narratives that reveal the rites and all symbolism of the past integrated to the present referring to different perspectives of true as to different conceptions of time and space, and the own identity formation. The narratives here represent this cycle where ruptures and reconfigurations are interpreted as the formation of a new humanity, but without the discontinuity of ancestry from memory. We search to draw a rupture, the arrival of civilization and its consequences, to the ancient people through a literary framework constructed by intermediaries, i.e. authors who realized the passage of a tradition, based almost entirely on ancient sources, producing research contemporary, manuals, dictionaries presenting information of the knowledge and culture from Amazon peoples.

Full textMetallic materials exposed to aquatic environments are susceptible to development of Microbiologically Influenced Corrosion (MIC). In industries MIC is a matter of great importance due to damages generated in repairs or equipment changes and production systems disruptions associated with technical failures. In this work are presented results of a MIC study on metal surfaces exposed to process water in a generating unit of hydropower, which suffers from an accelerated corrosion process, especially in the heat exchangers and the turbines. From corrosion biofilms sampled in turbines and heat exchangers were isolated bacterial groups sulfate reducing and oxidizing and reducing iron. These bacteria have been widely reported in the literature as inducing / aggravating the corrosion process.

Full textThe nuclear family has undergone changes over the last decades in its structure and in the way its members relate, mainly because of the feminine emancipation that enabled women to build a professional career, not restricting themselves to the mother role. The main objective of this thesis was to understand how parenting occurs in middle-upper-class heterosexual couples with children up to three years old, whose members are between 30 and 40 years old. As secondary objectives, we sought to understand the place the school and the pediatrician occupy in relation to the parental functions and to identify the notion that the interviewees have about child care. Eight couples, the pediatricians attending the children of these couples and the coordinators of the schools where the children of these couples study were interviewed. The interviews were recorded. Data analysis was carried out based on the psychoanalytical framework, with emphasis on the Winnicottian theory of personal maturation and the psychosocial and gender studies. Results were discussed in four categories: 1) maternal care and parental care; 2) possibilities of care: outsourcing and sharing; 3) to care in the interface with to educate: how to deal with limits and frustration; and 4) the parental, the conjugal and the individual. From this study, it was observed that tradition and innovation seem to coexist in the dynamics of parenting, and that the appropriation of parenting can be discussed in two areas. In the couples context, parenting was characterized by 1) greater fluidity in the parental roles; 2) parental equal care, with discursive predominance of an attribution to the greater value of the maternal figure; or 3) disruption with gender binarism in parental exercise, with a predominant attribution of responsibility to one parent. In a second context, considering the partnership established between parents and health and education professionals, these experts appeared as social representatives that could offer support and trust to the couple. In that sense, they offer holding to the parental holding, besides appearing as occupants of a place of orientation (in the case of pediatricians), or temporary substitutes for parental functions, in partnership with parents and / or third parties, representatives of culture, who stand between parents and children (in the case of schools). Among the notions of care found in the interviewees\' discourses, we highlight the paradox experienced by parents: a greater number of possibilities of life paths and different demands, related to individual satisfaction, marital satisfaction and the exercise of parenting, which may result in experiencing greater authenticity, but also greater anguish. It was emphasized that motherhood and fatherhood should be understood in their differences by the logic of alterity, and not by the difference of sex / gender

Full textThis paper carries out a comparative study between the novel Relato de um certo Oriente, by brazilian writer Milton Hatoum and Um rio chamado tempo, uma casa chamada Terra, by mozambican writer Mia Couto, with the purpose of verifying the construction strategies of memory. Based on the hypothesis that the memory, in these texts, is imagination of possibilities of the future that does not end up itself in fixed pictures, the thesis highlights the dominant techniques and issues of construction of the narrative through the use made by the authors of the travel motive, of the photograph, and of the epistolography in the composition of memory pictures. In order to reflect on the narrators that movie themselves on the imprecise space of mixtures, involved in complex cultural practices in interaction, it is looked for theoretical support and critical concepts as hybridism, miscegenation, transculturation, creolization and ambivalency. This critical exercise was done in the comparatism horizon of solidarity, proposed by Benjamin Abdala Junior to the studies of Iberian-Afro-American literatures.

Full textThe novel Sleepwalking Land by the Mozambican writer Mia Couto was published in 1992. In the same year, the war that raged Mozambique for sixteen years was coming to an end. The time of the narrative converges to the time of writing, turning the novel into an alternative narrative to historiography. The characters that represent the people are rehabilitated from the margins of official history. They become the actors of the little history, in which Mia Couto delineates certain idea of Africanness, tradition and national identity. Thus, this thesis intends to analyze the other history of Mozambique the author writes. For this, it searches in the interstices of the text the relationship with the context from the position occupied by Mia Couto in the Mozambican reality to the dynamics of war and its impact on the civilian population. At the same time, it searches the changes and continuities of postwar in order to correlate the history to be written (or the story to be told) on which it lays the hope of the novel.
Muramoto, Yuta. "Study of drilling properties in bone biomodel." Thesis, Lyon, 2020. http://www.theses.fr/2020LYSEC013.
Full textDrilling of bone is a fundamental surgical skill in specialties such as orthopedics, dentistry, and neurosurgery. Facing the aged society of our time, the number of surgical operations is estimated to increase along the enlargement in the proportion of elderly people. In order to fulfill the drastically growing demands of medical care, it is necessary to permit high-efficiency surgical training of doctors and development of performant medical devices. Bone biomodels are indispensable for surgical training and mechanical tests of medical devices, having their advantages in the ease of handling and consistency of material properties. However, a bone biomodel produced under the standard specification was reported to show different drilling characteristics compared to those of natural bone. In order to develop bone biomodels that cover drilling characteristics of natural bone, the objective of this thesis was to find out the relationship among drilling and mechanical properties, and tactile feedback during drilling. This is based on the assumption that drilling can be characterized by drilling properties described by cutting forces and cutting temperature, and those drilling properties are affected by mechanical properties of work materials, and likewise affects tactile feedback during drilling. In this study we fabricated composite materials consisting of acrylic resin and ceramic additives, and looked into the effects of additives on mechanical and drilling properties, and tactile feedback of composite materials. Drilling tests were carried out with the composite materials and controls such as natural bone and Sawbones test materials. Drilling were performed under both constant feed rate and constant thrust force. Besides, mechanical tests such as bending tests, microindentation tests, and fracture toughness tests were performed. Furthermore, tactile feedback during drilling was obtained by manual drilling of experienced surgeons. The experimental results suggested that additives can alter both drilling and mechanical properties. This effect becomes larger with the increase in additive amount up to 40 wt%. Acrylic composite materials including 20 wt% of alumina cement exhibit the good similarity to natural bone in tactile feedback during drilling. This result is considered to be attributed to equivalent thrust force during manual drilling, which is brought by the changes of mechanical properties of the acrylic resin owing to additives. Thrust force can be more dominant rather than torque in tactile feedback because the magnitude of applied force in vertical axis is one-hundred times larger than in lateral axis in drilling

Full textThis work suggests a methodology to disclosure effects of the cumulative taxes on the selling prices along the supply chain. We presented a panorama about the leather production segment in Brasil aiming to identify the main phases of the leather production process by measuring the effects of COFINS taxation that occurs in the segment. The methodological procedures adopted here allow us to verify the cumulative taxation in each referred phase by measuring the rate of in crease of the leather selling prices which occurs from one element to the following one of the supply chain, Through the methodology suggested we achieved to demonstrate that in each of the leather production phase (producer, slaughter, tannery, leather company) the increasing rates of selling prices was 4,27%, 5,56%, 5,23% and 4,97%, respectively. The method also indicates that the increasing rate of 7,91% on the selling prices relatives to the last phase correspond to the amount of tax added to the product. Though these percentage are valid only for these example utilized in this work, we conclude that this methodology applies to other cases and segments.

Full textThis doctoral thesis aims at the comparative study of the works of two mozambicans writers inserted on the macrosystem of literatures in Portuguese, Mia Couto and Paulina Chiziane. We worked on the theme of war from the perspective of the classic fantastic (Todorov, 2008), and the contemporary fantastic (Sartre, 2006; Bessière, 1974) in two novels, Terra sonâmbula (Couto, 1992) and Ventos do apocalipse (Chiziane, 1999) considering them as spaces for dialogic discussion, in continuous transformation and determined by history. (Bakhtin, 1988; Lukacs, 2006). Our comparative approach sought to tie the issues concerning the theory of alien to own in order to provide a better understanding of the Mozambican literature and its context. In addition, through this possibility of greater understanding, facilitate their dissemination.

Full textChipping wood of second quality is a rapidly growing process because of the increasing use of the biomass in energy production field. The utilization of wood chips as a combustible, make it easier to automate the wood boilers function. Few studies were carried out in order to understand the mechanism of the chip formation and the evolution of cutting force during the chipping operation. In this thesis, we focused our analysis on the disc chipper. A test bench of real dimensions was built up in order to be able to vary many parameters such as cutting and feeding speed, cutting angles, feeding direction, anvil height, cutting directions, knives number and their height.Experimental study showed that chip size grows when the feeding tooth, the cutting angle and the sharpness angle increase, whereas it decreases when the cutting speed increases. The process of the chip formation is composed of two mechanisms that are shear and cracks propagation. Measurement of cutting force and electric power consumption for a bandwidth up to 3 kHz bring important results to the chip size study. The chipping test bench allowed us to reveal the correlation or the independency between the parameters needed to optimize the chipping operation

Full textThe aim of the work is to promote the ammoniacal nitrogen removal from anaerobic baffed reactor effluent using aerobic trickling filters, through the nitrification process. The research was developed in two phases; firstly the leather sawing was prepared through sieving and washing, later the domestic sewage was applied into four tricking filters. The F1 and F2 filters were operated with the same hydraulic loading (1,91 'M POT.3'/'M POT.2'.day) and different filter packing. For the F1 filter was used rock and for the F2 wet blue leather sawing. The F3 and F4 filters were filled with leather sawing and operated in a hydraulic loading of 4,00 and 6,00 'M POT.3'/'M POT.2'.day respectively. The F3 filter presented better removal efficiencies for all the parameters, with 70% of average removal efficiency of KTN (Kjeldahl Total Nitrogen), 'NH IND.3'-'N' (ammoniacal nitrogen) and COD (Chemical Oxygen Demand). From the 49th day on, this filter presented 100% of removal efficiency of KTN and 'NH IND.3'-'N'. The F1 and F2 filter were supposed to present better results due to the lower hydraulic loading, but it did not happen, probably because the aeration was not enough. The F4 filter presented low removal efficiency, possibly due to the higher hydraulic loading.

Full textFrom the moment of the baby\'s conception, the parents build through their desires, an entire symbolic net to support him psychically, the same net that their ancestors are part of. Through the name the parents give, the child receives its enrollment in the family and can be born subjectively. This research aimed to reflect on the unconscious motivations that underlie the choice of the names of the firstborn child, by pregnant mothers, in order to observe the influence of the psychic mechanism of transmission over generations, specifically about the place this child will occupy in the current family and in the generational chain, beyond contributing to building knowledge in the area of Psychoanalysis of couple and family. The clinical qualitative methodology was used for data collection and discussion of the content obtained from the semi-structured interviews with five pregnant women, of four male and one female baby. The psychoanalytic genogram was also requested to the pregnant women. The results showed that in the analysed cases the names given to the children are associated to the family legacy, to the mechanism of psychic transmission and intergenerational conflicts. The act of naming the children with the surname is also one of the ways to assume parenting as well as to include the child in their social and generational continuity

Full textINTRODUCTION: Self accomplishment through maternity and paternity is often one of the most important life projects for an individual or couple and one of the basis over which the couple constructs their relationship. Because it represents an interruption in the couples life project, the infertility diagnosis may generate difficulties in the social, familiar and conjugal relationships not always easily overcome. The oocyte donation is an assisted reproduction technique in which the female gamete is provided by a different woman from the one which will receive the resulting embryo. These techniques may help infertile couples in their parenting project. OBJECTIVES: Considering the relatively recent quality of the process, as well as the lack of systematized national data concerning the psychological issues involved in the process of oocyte donation, the present study had as its general objective to investigate the self-referred experiences of potential oocyte donors and receptors enrolled in a oocyte donation program; it also aimed to identify the main reasons referred by women for being oocyte donors or receptors; comprehend the referred fantasies of these women towards the process; and offer the health team the support to work through the process in a more effective and integrated manner. METHODS: The study was conducted in the Human Assisted Reproduction Center of the Medical School of ABC. All women enrolled in the Oocyte Donation Program between May of 2006 and May of 2008 was invited to participate in the study. Within this period there were 23 women, ages between 21 and 35 years, candidates to the oocyte donation, and 58 women, ages up to 53 years, candidates to the oocyte reception. Data was collected through semi-direct interviews, following a previously elaborated interview guide; the medical records were also used for detecting the medical diagnosis. RESULTS: We were able to observe that the wish for pregnancy, the chance of becoming a mother and constructing a family were the main reasons given by women for being oocyte receptors; on the counterpart, a new problem would have to be dealt with by these women: the existence of a forth party, a more potent woman; besides that, there was the secrecy situation, as well as the keeping of the secret from the child conceived from the procedure. As to the donors, helping another woman was the main reason referred by them for participating in such a program. There is in fact disposition to help, however, not with altruistic characteristics, for there is an expectation of gains concerning the way they will be seen and treated by the medical team in consequence of their donation, as well as expectations of a positive result (pregnancy) for their own treatment. FINAL CONSIDERATIONS: The comprehension of this complex constellation seems to be essential for the proposal to be well succeeded. The data obtained suggests the existence of a universe full of fantasies, fears, and expectations that permeate the experience of participating in a Oocyte Donation Program, showing also the importance of prospective studies concerning oocyte donation situations, no matter if they are successful or not

Full textThis research aims to analyze Gabriel Naudés theory of the coups détat , one of the main authors of reason of State on the 17th Century. Interpreting Naudés magnum opus, Considérations politiques sur les coups dÉtat (1639), I intend to explore not only his conceptual basis but the theoretical tendencies leading to his writings. Through this investigation it is possible to deem prudence as the major supporting notion of the theory of the coups détat, which was essentially influenced by the works of Justus Lipsius and Pierre Charron. Thence, I intend to deconstruct Naudés notion of prudence in order to point out the weigh of Lipsius and Charrons ideas on his work, showing the existence of other references in the formulation of the reason of State on this epoch, besides Niccolo Machiavelli.

Full textPhosphomannose isomerases (PMI) are metalloenzymes catalyzing the reversible isomerization of mannose-6-phosphate to fructose-6-phosphate. These enzymes, classified into three types according to their sequence and their physico-chemical properties, are essential for the survival and the proliferation of many microorganisms. The low sequence homology between bacterial, like Pseudomonas aeruginosa, and human enzymes suggest PMI as potential therapeutic targets. Nevertheless, crystallographic and inhibition studies were largely unexplored at the beginning of this work. So, elucidation of PMI's catalytic mechanism appears as a main goal. For this reason, in addition to research of new PMI activity tests, synthesis and kinetic studies of new potential inhibitors were investigated, as well as polarizable molecular mechanics and quantum mechanics studies of Candida albicans PMI. All the results allowed us to propose the first catalytic mechanism for the PMI-catalyzed reaction, underlying critical points: (i) the metallic cofactor of the active site would play an important role in the recognition and the stabilization of the substrate, as well as it would play a catalytic role as Lewis acid, (ii) the phosphate moiety in a secondary role would be essential for the molecule docking at the active site of the enzyme, and finally (iii) deprotonation of the substrate would imply a catalytic triade metal-Glu-Lys where the catalytic base would be the neutral lysine
Yang, Kang. "Numerical and semi analytical models for electromagnetic ring expansion test." Thesis, Compiègne, 2017. http://www.theses.fr/2017COMP2350.
Full textHigh stain rate material deformations are prevalent during high speed impacts, high speed forming/welding, cutting, crimping, blast etc. Characteristics of materials under high strain rate deformation do not follow the same as it occurs under the quasi-static loading conditions. However, characterization of materials under high strain rate deformation is always challenging and it requires sophisticated equipment. Thanks to the development in electromagnetic forming technology, the electromagnetic ring expansion test shows a great potential to be used to characterize materials under high strain rate conditions. During the electromagnetic ring expansion test, the workpiece can reach deformation velocities in the order of 100 m/s and a strain rate of up to 104 s-1. Consequently, this test can be used to predict the material parameters such as the strain rate hardening and ductility under extremely high strain rates (strain rates in the order of 103 – 104 s-1). In order to achieve this goal, an appropriate model is required to describe the process. The model should contain an electromagnetic-mechanical-thermal coupling to obtain the accurate multi-physics nature of the problem. There exist two main modeling methods in literature, viz., the semi-analytical methods and finite element methods (sometime combined with boundary element method). Normally, the semi-analytical methods require short calculation time while it provides lower accuracy in comparison with finite element methods. However, due to the complexity of multi-physics coupling, the calculation error is difficult to be analyzed. Moreover, errors in calculation and identification assumptions may also result from heterogeneous deformations or localized specific phenomena (such as local necking at multi points or electric current localization, skin effect, edge effect of Lorentz force etc.) that could influence identification work as well as stress and strain states. Therefore, this thesis mainly focused on the analysis and modeling methods of ring expansion test including local behaviors and dynamic phenomena with the help of experimental and numerical tools. Moreover, this thesis also includes a development of a semi-analytical method with multi-physics coupling capabilities, which has been validated using a theoretical model and experimental frameworks. Experimental measurements were obtained using high-speed cameras and photonic Doppler velocimetry (PDV) for various test cases are used together with numerical models to investigate the process and material parameters. The models used to analyze the stress and stain states during a ring expansion test show that the ring expansion test is not a pure uniaxial tensile test as claimed by researchers. Besides, another potential process behavior, the vibration phenomena that occurs during the elastic recovery was investigated using multi-physics simulations and PDV systems. This investigation of the elastic recovery helps to understand the potential influencing parameters of the test those are applicable and could be used to control the springback phenomenon during other electromagnetic forming processes. The semi-analytical modeling method for ring expansion test including four calculation parts (mechanical part, eddy current, Lorentz force calculation, thermal part) were analyzed with the help of numerical simulations. The results obtained from analytical work closely resemble with the numerical simulations for both theoretical model and an experimental case study. The error analysis of various physical aspects allows improving the accuracy of semi-analytical calculation that could be used as an additional platform to obtain rapid calculation of the test conditions. This semi-analytical method could be extended in the future to identify material parameters under high strain rate deformations

Full textIn 1964 at least three Military Police Investigations (IPM in the Portuguese language acronym) were launched in schools of the University of São Paulo, with the stated objective of assessing and curtailing subversive activities. Only one of these had juridical effects, derived from the Institutional Act of April 9, 1964, which was the IPM on the Medical School. Based on it, the State Governor fired seven professors from several departments (Erney Camargo, Luiz Hildebrando Pereira da Silva, Thomas Maack, Luiz Rey, Pedro Henrique Saldanha, Julio Pudles, Reynaldo Chiaverini). This work aims at demonstrating the contribution of the Revolutionary War doctrine, which was at the time adopted by the Brazilian military, for the conduction of the IPM investigation, as well as its role in internal dissensions existing in the Brazilian Armed Forces which manifested itself intensely during the first months of the Castelo Branco government. Particularly, the Medical School IPM can be seen as demonstrating convergence between the momentum given by the Revolutionary War doctrine to the investigation, and the special interests of those who had the power and authority to manage the University of São Paulo with the objective of precluding change.
