The aim of this research is to investigate guidelines for formulating questions to interview applicants of identity documents, for the use of the Department of Home Affairs (DHA) officials during the interviewing of applicants of identity documents. The research further intends to share and introduce a number of important concepts, namely: Interviewing, Crime Investigation, Information, Identity Docu-ment, Immigration Officer, Department, and Case File. The research will explain the objectives of investigation and guidelines for developing proper questions for use by officials of the DHA, to test information on new applicants of identity documents. The object of the investigation is to obtain information to prove the correct techniques on how to interview appli-cants of identity documents. It further explains that criminal investigation can be defined as the process of discovering, collecting, preparing, identifying and presenting evidence, to deter-mine what happened and who is responsible. Interviewing is defined as the process of gathering testimonial evidence through interviewing, and it has a predetermined objective, namely discovering the truth about the matter under investigation. It is also explained that during guidelines for formulating relevant questions to use to enable the official or immigration officer to formulate test questions that are clearly understood better by DHA. The relevant questions should be formulated by DHA officials, so that the questions get to the heart of the issue. This can enable the official to avoid applicants submitting fraudulent documents which could later result in litigation. The research will assist in decreasing the high rate of corruption, and also litigation, as these represent the main problem of the research. / Criminology and Security Science / M. Tech.

This study focused on records management in churches, particularly the Friends Church (Quakers) in Kenya. The study sought to find out the record types and formats created or received, establish records management systems currently being used, investigate the challenges faced in managing the records, and assess the status quo in records management as well as recommend possible solutions for the Friends Church in Kenya. Both qualitative and quantitative were used to collect data from the field. Through interviews, data was collected from pastors, church administrators, and church members. Exploratory research design was adopted in conducting in-depth interviews among the participants in order to understand records management practices in the Friends Church in Kenya and provide recommendations for improvement. Purposive sampling technique was adopted to select a sample size of 24 participants who included individuals with relevant information about records management in the Friends Church in Kenya. The response rate for this study was 100 percent. The study discovered that records created or received by the Friends Church in Kenya were not properly managed. This was due to lack of an electronic system of records management, inadequate qualified personnel to manage records, inaccessible records when needed, lack of fire protected cabinets, poor leadership, among others. These culminated to time wastage in churches, conflicts, overspending on various church activities, unproductivity, loss of file(s) that contain vital information, poor organization and culture, and some committed church members left the church. The Study concluded that for the Friends Church to achieve operational efficiency, it is important that the church leadership establish records management offices that are equipped with requisite resources to effectively manage paper based records and electronic records. / Information Science / M.

De nombreuses avancées ont été réalisées en termes de géométries instrumentales, mouvements de travail et procédés de fabrication des limes endodontiques. Cependant, peu de recherches se sont tournées vers l’utilisation d’alliages à mémoire de forme (AMF) autres que le Nickel-Titane (NiTi). Ce travail se propose de développer un instrument endodontique constitué d’un nouvel AMF aux propriétés mécaniques et antimicrobiennes très prometteuses : le CuAlBe monocristallin. Après une première analyse par éléments finis des paramètres géométriques adéquats pour une lime endodontique en AMF monocristallin à base de CuAlBe, plusieurs prototypes ont été fabriqués puis testés en rotation continue selon un protocole de pénétration / retrait (P/R) dans des canaux artificiels. Des limes endodontiques en NiTi, déjà commercialisées, ont été également testées avec le même protocole. L’objectif de ces recherches était de montrer que les instruments endodontiques en CuAlBe monocristallin présentaient des performances mécaniques équivalentes à ceux en NiTi, en plus de leurs propriétés antimicrobiennes / Many advances have been made in terms of instrumental geometry, working motion and manufacturing processes of endodontic files. However, since the discovery of Nickel-Titanium (NiTi) shape memory alloys (SMA), few research has been carried out on new SMAs. In this context, this work aims to develop an endodontic instrument machined from a new SMA with very promising mechanical and antimicrobial properties: the single crystal CuAlBe. Following a finite element analysis in order to determine adequate geometric parameters for a single crystal CuAlBe SMA endodontic instrument, prototypes were machined and tested following a continuous rotation penetration / removal (P/R) protocol in artificial canals. Endodontic files made of NiTi SMA, already commercialized, were also tested with the same protocol. The aim of this researches is to show that CuAlBe endodontic instruments could lead equivalent mechanical performances to NiTi instruments in addition of their antimicrobial properties

As a hypothesis, we have guided ourselves by the fact that Revista piauí proposes a disruption in contemporary reading practices, which are sometimes characterized by the predominance of pictures and utilization of short objective texts that are addressed to readers who have little time to inquire. Against this order, piauí resists e defines itself as a magazine for those who like to read. The magazine proposes the retaking of literary journalism, which is characterized by long authorial reports. Methodologically, we have selected the linguistic regularities in order to identify the discursive formation the magazine has adopted. We have analyzed, based upon the notion of discursive genre proposed by Bakhtin style, compositional structure and thematic content , the genre subversions and their effects of meaning. In addition, we have also tried to identify Revista piauí resistance fields on themes, language, reading practices. We have considered the concept of resistance as according to Michel Foucault: there is not any single power in society, but a relation of powers and resistances. From this relation among powers and resistances, we have tried to identify the presence of the interdiscourse the discursive memory that penetrates through the new publication. piauí has adopted a 1960 s resistance journalism, which was mainly symbolized by O Pasquim, a weekly publication that reflected Southern Rio de Janeiro city lifestyle. Considering that the nomination piauí refers to the smallest and poorest state of Brazilian Federation and that the new magazine title comes from a Tupi-Guarani-originated expression, some final conclusions assign to the magazine an anthropophagous approach that makes piauí spread Brazility files, and the magazine irruption is linked with a feasible place for the Brazilian experience in the actual context. / Amparada no referencial teórico da Análise do Discurso derivada de Michel Pêcheux e nos estudos do discurso como propostos por Michel Foucault e Jean-Jacques Courtine, a pesquisa objetiva acompanhar e avaliar as treze primeiras edições da revista piauí, cujo primeiro número data de outubro de 2006, com vistas a reconhecer nessa publicação a instalação de um acontecimento discursivo. Como hipótese, pautamo-nos no fato de que a revista piauí propõe um rompimento com as práticas de leitura contemporâneas, marcadas, por vezes, pelo predomínio da imagem e pela utilização de textos curtos, objetivos, destinados a um leitor com pouco tempo para se informar. Contra essa ordem, piauí resiste e se define como a revista para quem gosta de ler. A revista propõe a retomada do Jornalismo Literário, marcado por reportagens longas e autorais. Metodologicamente, recortamos as regularidades lingüísticas para identificar as formações discursivas às quais a nova revista se filia. Analisamos, a partir da noção de gênero discursivo proposta por Bakhtin o estilo, a estrutura composicional e o conteúdo temático , as subversões genéricas e os seus efeitos de sentidos. Procuramos, ainda, identificar os campos da resistência em piauí na temática, na linguagem, nas práticas de leitura. Consideramos o conceito de resistência conforme o formula Michel Foucault: não existe um único poder na sociedade, mas uma relação entre poderes e resistências. A partir dessa relação, procuramos identificar a presença do interdiscurso a memória discursiva a permear a nova publicação. piauí se filia a um jornalismo de resistência dos anos 60, simbolizado, principalmente, pelo semanário O Pasquim, que refletia certo estilo de vida da zona sul carioca. Considerando que a nomeação piauí remete ao menor e mais pobre estado da Federação Brasileira e que o nome da nova revista advém de uma expressão originária do tupi-guarani, algumas conclusões finais encaminham-se para atribuir à revista uma abordagem antropofágica que faz piauí circular arquivos de brasilidade , e sua irrupção se relaciona com um lugar possível para a experiência brasileira no atual contexto.

Nous étudions les systèmes de véhicules en libre service en aller-simple : avec emprunt et restitution dans des lieux éventuellement différents. La publicité promeut l'image de flexibilité et d'accessibilité (tarifaire) de tels systèmes, mais en réalité il arrive qu'il n'y ait pas de véhicule disponible au départ, voire pire, pas de place à l'arrivée. Il est envisageable (et pratiqué pour Vélib' à Paris) de relocaliser les véhicules pour éviter que certaines stations soient vides ou pleines à cause des marées ou de la gravitation. Notre parti-pris est cependant de ne pas considérer de ``relocalisation physique'' (à base de tournées de camions) en raison du coût, du trafic et de la pollution occasionnées (surtout pour des systèmes de voitures, comme Autolib' à Paris). La question à laquelle nous désirons répondre dans cette thèse est la suivante : Une gestion via des tarifs incitatifs permet-elle d'améliorer significativement les performances des systèmes de véhicules en libre service ? / One way Vehicle Sharing Systems (VSS), in which users pick-up and return a vehicle in different places is a new type of transportation system that presents many advantages. However, even if advertising promotes an image of flexibility and price accessibility, in reality customers might not find a vehicle at the original station (which may be considered as an infinite price), or worse, a parking spot at destination. Since the first Bike Sharing Systems (BSS), problems of vehicles and parking spots availability have appeared crucial. We define the system performance as the number of trips sold (to be maximized). BSS performance is currently improved by vehicle relocation with trucks. Our scope is to focus on self regulating systems through pricing incentives, avoiding physical station balancing. The question we are investigating in this thesis is the following: Can a management of the incentives increases significantly the performance of the vehicle sharing systems?

In them we find four poor children who were raped at the turn of the nineteenth and early twentieth centuries. With the theoretical framework and methodology supported in Michel Foucault, the main trunk of the research is focused on the rescue of those children stories from the perspective of their own accounts. It is also the object of this work to investigate, through the intersection of the four procedural documents, the particularities of each of the crimes, unraveling how abused those children faced intensifying legal actions in their lives, and how the devices of sexuality and alliance, which had as a principle meet the medical/legal policy that historical period, seeking to punish deviant behavior, across each of those bodies. The study also found that the way assimilated elite and used the legal instrument to build their worldviews. We conclude with the work the new world designed in the late eighteenth century was built by and for the ruling elite. The speeches, laws and standards in Lawsuits recorded camouflage schemes standardization of social life, which led to all, in defiance of the law were to apply the few ( the only undesirable ). As one of the conclusions of the study it appears that the trials worked, actually, as an educational showcase the deviant, sanctioning their actions and berating his excesses. The shock of these infamous power with children was the only way to get out of the dark stories. Without this meeting, we would never know of their existence. / Esta Dissertação é fruto de uma pesquisa realizada em dois Processos Criminais e dois Inquéritos Policiais descobertos no Arquivo Público e Histórico de Ribeirão Preto. Neles encontramos quatro crianças pobres que foram violentadas na viragem do século XIX e início do XX. Com referencial teórico e metodologia apoiados em Michel Foucault, o tronco principal da pesquisa é voltado para o resgate das histórias daquelas crianças sob a ótica de seus próprios relatos. É também objeto deste trabalho investigar, por meio do cruzamento dos quatro documentos processuais, as particularidades de cada um dos crimes, desvendando como as crianças violentadas enfrentaram a intensificação daquelas atuações jurídicas em suas vidas, e como os dispositivos da sexualidade e da aliança, que tinham como princípio atender à política médico/jurídica daquele período histórico em busca de punir condutas desviantes, atravessou cada um daqueles corpos. O trabalho verificou, também, de que maneira a elite assimilava e utilizava o aparelho jurídico para construir suas visões de mundo. Concluímos com o trabalho que o novo mundo desenhado no final do século XVIII foi construído pela e para a elite dominante. Que os discursos, Leis e normas existentes nos Processos Judiciais registravam esquemas camuflados de normalização da vida social, que dirigidos a todos, ao arrepio da Lei, eram aplicáveis a poucos (somente aos indesejáveis). Como uma das conclusões do trabalho verifica-se que os julgamentos funcionavam, na verdade, como uma vitrine pedagógica aos desviantes, sancionando suas ações e repreendendo seus excessos. O choque destas crianças infames com o poder foi a única maneira de suas histórias saírem da obscuridade. Sem este encontro, nunca saberíamos de suas existências.

Na tentativa de superar as limitações desses instrumentos menos flexíveis foi desenvolvida a utilização da liga com memória de forma (LMF) de NiTi (Níquel-Titânio) para fabricação de instrumentos endodônticos. A utilização desses instrumentos endodônticos de NiTi modificou os métodos de instrumentação do sistema de canais radiculares, tornando-os mais seguros e rápidos. No entanto, ainda existem poucas informações sobre o comportamento termomecânico destes instrumentos mais avançados. Nesse contexto, no presente trabalho foram realizadas as caracterizações térmica e mecânica de três limas endodônticas de LMF NiTi: Protaper Next X2, Reciproc R25 e WaveOne Primmary. Na caracterização térmica foram realizados ensaios de calorimetria diferencial de varredura (DSC) e resistência elétrica em função da temperatura (RET) para a determinação das temperaturas de transformação de fase das limas, enquanto a caracterização mecânica consistiu de ensaios de flexão simples alternada em regime estático e dinâmico (frequência de 5 Hz) a diferentes temperaturas e deflexões máximas, usando um Analisador Dinâmico Mecânico (DMA) e finalizou com uma análise pós fagida com ensaios de calorimetria diferencial de varredura (DSC) e análise das superfícies fraturadas com um Microscópio Eletrônico de Varredura (MEV) Os resultados obtidos com as três limas revelaram que estes instrumentos endodônticos se encontram na fase conhecida como Fase R, os ensaios quase estáticos revelaram uma forte dependência da Força requerida e a Temperatura, os ensaios cíclicos em flexão alternada para impor deflexões na faixa de ±0,5 mm a ±2,0 mm as limas Reciproc R25 mostraram maior tempo de vida cíclica do que as demais, e com o aumento da temperatura de teste de 35 oC para 45 oC, verificou-se que a força para impor as deflexões foram maior e a vida em fadiga das limas reduziu consideravelmente. / Endodontic therapy performed on curved root canals with stainless steel files can cause many iatrogenic accidents, resulting in problems such punctures the canal. In an attempt to overcome the limitations of the less flexible instruments, the alloy with shape memory and NiTi (Nickel-Titanium) for manufacturing endodontic instruments were developed. The use of the NiTi instruments modified methods of instrumentation of the root canal system, making them safer and faster. However, there is still little information on the thermomechanical behavior of more advanced instruments. In this context, the present work is done the thermal and mechanical characterization of three endodontic commercial LMF NiTi files: Protaper Next X2, Reciproc R25 and WaveOne Primmary were performed. For thermal characterization were performed differential scanning calorimetry (DSC) tests and electric resistance as a function of temperature (RET) for determining phase transformation temperatures of files, while the mechanical characterization consisted of static bending tests and dynamic regime (5 Hz frequency) at different temperatures and maximum deflections using a Dynamic Mechanical Analyzer (DMA) and finalizes with post fracture analysis with differential scanning calorimetry (DSC) and fractured surface analysis with an Electron Microscope. The results obtained with the three files showed that endodontic files are in phase known as Phase R, the quasi static tests revealed a strong dependence of the Required Force and the Temperature, the cyclic tests in alternating bending to impose deflections in the Range from ± 0.5 mm to ± 2.0 mm, the Reciproc R25 showed longer cycle life than the others, and with the test temperature rise from 35 °C to 45 °C, it was found that the force to impose the deflections were higher and the fatigue life of the limes reduced considerably.

Conversely, state industries manufacture only low added value red ceramics. Porcelainized stoneware tiles is one of the noblest ceramics, depicting low water absorption (typically below of 0,5%), in addition to excellent staining resistance and mechanical strength. The present work aims at investigating the potential of local raw materials for the production of porcelainized stoneware tiles. To that end, these materials were characterized by X-ray fluorescence, X-ray diffraction, particle size analysis, thermal gravimetric analysis and thermal differential analysis. Admixtures containing different compositions were prepared and fired at three temperatures, 1150, 1200 and 1250?C for 30 min. After firing, tests samples were characterized by water absorption tests, linear retraction, dilatometric analysis, apparent porosity, apparent specific mass, flexural strength, and microstructural analysis by XRD and SEM.

For more than 50 years it helped the social and economical development of the city through activities focused in wool production and commercialization. In 2003 the factory terminated its activities due to bankruptcy. In the year of 2010 Universidade Federal de Pelotas, Federal University of Pelotas, bought the Laneira's building to install some branches of the University and to create a memorial of the extinct factory. Inside of the building a variety of artifacts, like photographs, were found which can lead to new interpretations of the factory's path. This study will discuss photography as historical documents to the industrial heritage, in the Laneira Brasileira S. A.'s case, evidencing systematic methodologies which can bring information about the manufacturing of this company. It is believed that the organization of the Laneira's photographic collection is fundamental to understanding its history while the factory was in full operation. This organization contributes to the creation of the memorial related to this patrimonial heritage of Pelotas / A Laneira Brasileira Sociedade Anônima, localizada no Bairro Fragata, em Pelotas/RS, foi uma importante indústria para a comunidade pelotense, ajudando no desenvolvimento econômico e social da cidade, por meio das atividades voltadas para produção e comercialização de lã, durante mais de cinquenta anos. Devido à falência, a Laneira encerrou seu processo de beneficiamento da lã em 2003. No ano de 2010, foi adquirida pela Universidade Federal de Pelotas para a instalação de novas unidades da instituição, bem como a constituição de um memorial sobre a extinta indústria. De seu espaço foram resgatados inúmeros artefatos materiais, os quais levam a imaginar e a reinterpretar a trajetória desse local, como as fotografias. O presente trabalho objetiva discutir as possibilidades da fotografia como suporte para o patrimônio industrial, no caso do Memorial da Laneira Brasileira S. A., evidenciando metodologias de sistematização que possibilitem trazer informações a respeito do trabalho fabril dessa indústria. Acredita-se que as ações efetivadas para a organização do acervo fotográfico da Laneira sejam fundamentais para a compreensão de sua história no período de seu funcionamento, contribuindo para a criação do memorial referente a esse patrimônio industrial pelotense
