O objetivo do presente estudo in vitro foi avaliar a área ocupada pela guta-percha e cimento, bem como a resistência de união em canais radiculares obturados por diferentes técnicas: Schilder Modificada, Cone único, Thermafil e Híbrida de Tagger. Quarenta incisivos centrais superiores foram preparados com instrumentos rotatórios de NiTi até o diâmetro cirúrgico #70.02, e divididos em quatro grupos de acordo com a técnica utilizada para obturação dos canais (n=10): GI - Schilder Modificada, GII - Cone Único, GIII - Thermafil e GIV - Híbrida de Tagger. Os canais foram obturados com o cimento AH Plus misturado ao corante Rodamina. Feitas as obturações, realizou-se a remoção coronária e as raízes foram seccionadas no sentido horizontal, obtendo-se 3 fatias (2mm de espessura): cervical, médio e apical. Após o preparo, as fatias foram submetidas à mensuração da área total do canal radicular e da área de guta-percha, por meio de objetiva Plan S 1.0 X acoplada à câmera digital e do software Axiovision 4.8. A área do cimento obturador foi determinada pela fórmula Área do cana = Área guta-percha + Área cimento + Área espaços vazios. A resistência de união foi avaliada pelo teste de push-out e as falhas foram observadas em microscópio digital. Os dados foram analisados por Análise de Variância a dois critérios e teste Tukey HSD (p<0,05). Verificou-se diferença estatisticamente significante para técnica obturadora (p<0,05). Não houve diferença estatisticamente significante nos terços e para interação dos fatores (p>0,05). Os canais obturados pelas técnicas Thermafil e Schilder Modificada proporcionaram maiores áreas de guta-percha, diferindo estatisticamente dos obturados pelas técnicas de Cone único e Hibrida de Tagger (p<0,05). Na análise da área preenchida pelo cimento, verificou-se que nos espécimes obturados pelas técnicas Thermafil e Schilder Modificada houve menor área ocupada pelo cimento, diferindo dos obturados pelas técnicas Híbrida de Tagger e Cone Único (p<0,05). Na análise da resistência de união, houve diferença significante para técnica obturadora, terços e para a interação dos fatores (p<0,05). Os canais obturados pela técnica Híbrida de Tagger apresentaram maior valor de resistência de união, diferentes dos obturados pelas técnicas Cone Único, Schilder Modificada e Thermafil (p<0,05). Houve diferença estatisticamente significante entre os terços (p<0,05), sendo que o terço apical apresentou o maior valor de resistência de união. A análise da interação técnica versus terço demonstrou que os espécimes obturados pela técnica Híbrida de Tagger tiveram no terço apical a maior resistência de união, diferentes das demais técnicas e terços (p<0,05). Falhas adesivas foram mais frequentes em todos os grupos. Pode-se concluir que a maior área ocupada pela guta-percha e a menor área ocupada pelo cimento foram encontrados nos espécimes obturados com as técnicas Schilder Modificada e Thermafil. O maior valor de resistência de união foi encontrado nos canais obturados pela técnica Híbrida de Tagger, especialmente no terço apical. / Ther purpose of this in vitro study was to evaluate the area occupied by gutta-percha and sealer, as well the bond strength in root canals obturated with different techniques: Schilder&prime;s Modified, Single Cone, Thermafil and Tagger&prime;s Hybrid. Forty maxillary central incisors were prepared with NiTi rotary instruments to the diameter #70.02, and separated in four groups according to the technique used for root canal filling (n=10): GI - Schilder&prime;s Modified, GII - Single Cone, GIII Thermafil and GIV - Tagger&prime;s Hybrid. The roots canals were filled with sealer AH Plus mixed with Rhodamine dye. After obturation, coronary was removed and the root&prime;s were sectioned in the horizontal direction, obtaining 3 slices (2 mm thick): cervical, medium and apical. After preparation, the slices were subjected to measurement of the total roots canal area and gutta-percha&prime;s area, through objective Plan S 1.0 X coupled to the digital camera and Axiovision 4.8 software. The sealer&prime;s area was determined by the formula: roots canal&prime;s area = gutta-percha&prime;s area + sealer&prime;s area + void&prime;s area. Bond strength was evaluated by push-out test and the failures were observed in digital microscope. The results were analyzed by ANOVA two-way and Tukey HSD (p <0.05). It has been found a statistically significant difference for techniques (p <0.05). There was no statistically significant difference in thirds and interaction of the factors (p> 0.05). Root&prime;s canal filled by Thermafil and Schilder&prime;s Modified had higher gutta-percha&prime;s area than Single Cone and Tagger&prime;s Hybrid techniques (p <0.05). The analysis of the sealer&prime;s area, proved that the specimens filled by Thermafil and Schilder&prime;s Modified had smaller sealer&prime;s area, differing from Tagger&prime;s Hybrid and Single Cone (p <0.05) techniques. Bond strength&prime;s results demonstrated a significant difference for techniques, thirds and the interaction of this factors (p <0.05). Roots canals filled by Tagger&prime;s hybrid technique had higher bond strength than Single Cone, Schilder&prime;s Modified Thermafil techniques (p <0.05). There was a statistically significant difference between the thirds (p <0.05), and the apical third showed the highest bond strength&prime;s value. The analysis of interaction technique versus third, showed that the specimens filled by Taggers Hybrid in the apical third had the highest bond strength, different from the other techniques and thirds (p <0.05). Adhesive failures were more frequent in all groups. It was concluded that the highest area occupied of gutta-percha and the less sealer&prime;s area were found in roots canals filled with Schilder&prime;s Modified and Thermafil techniques. The highest bond strength was found in roots canals filled by Tagger&prime;s Hybrid technique, especially in the apical third.

Therefore, the phenomena related to the work hardening must be understood and mastered, once the strain has an extremely important function on the phase transformation of these materials. For the investigations, are conducted different kinds of strains on the stainless steels by filing, compression and cold rolling at 12%, 31%, 50%, 70%, 80% and 90% reduction levels. In order to compare the materials, are conducted the following technics: optical microscopy, EDS, EBSD, X ray diffraction, hardness measurements and ferritoscope. The high hardness presented by these as received materials is attributed to the fact that they were not annealed. Low rolled steels showed high transformation into ε-martensite, and high rolled levels (like 90%) showed high grain elongation and very high α’- martensite fractions. Filling and compression also showed high α’- martensite fractions for the AISI 304. However, the AISI 316 didn’t show a significant fraction of α’- martensite after the compression test. Therefore, the high hardness showed by AISI 316 steel after the compression test is certainly due to classic work hardening mechanisms, not due to a α’- martensite transformation, which depends on the Stacking Fault Energy (SFE). / Aços inoxidáveis com propriedades que permitam alta conformabilidade aliada a resistência mecânica satisfatória devido a transformações de fase vêm sendo destaque nas indústrias e centros de pesquisa de metalurgia. Para tanto, os fenômenos relacionados ao encruamento devem ser compreendidos e dominados, pois os processos de deformação desempenham uma função extremamente importante na transformação de fases desses materiais. As investigações são conduzidas com deformações plásticas nos aços inoxidáveis por meio de limagem, compressão a 60% de redução da altura e laminação a níveis de 12%, 31%, 50%, 70%, 80% e 90% de redução. Para fins comparativos, são conduzidas análises microestruturais por meio de: microscopia óptica, EDS, EBSD, difração de raios X, medidas de dureza e ferritoscopia. Percebeu-se uma dureza acima do esperado nos materiais inicialmente caracterizados devido ao fato de os mesmos não estarem na condição de recozidos. Baixos níveis de redução na espessura promoveram elevados índices de transformação da austenita para martensita ε, enquanto que altos níveis de redução resultaram em elevado alongamento dos grãos e as maiores frações de martensita α’ entre todas as condições de deformação. Deformação por meio de limagem e por meio de compressão promoveram altos índices de transformação da austenita em martensita α’ para o aço inoxidável AISI 304, porém quando submetido à compressão, o aço AISI 316 não apresentou consideráveis frações de martensita na microestrutura. Sendo assim, conclui-se que o aumento de dureza do aço AISI 316 se deu por mecanismos clássicos de endurecimento, e não pela formação de martensita induzida por deformação. Isso porque a tendência em formar martensita induzida por deformação é dependente da EDE, e consequentemente, da composição química do material.

To this end, the research attempts to historicize the emergence of this manuscript, highlighting its peculiarities. Initially, this research will seek to understand the Memorial in its material reality: on one hand, the different media of writing (books, notebooks, material manipulatives); and on the other hand, the elements that influenced on its own existence and meaning conditions (the general lack of resources, the reuse of pages, the concise writing and the likelyintertextuality). Then, its textual surface will be analised. In an effortto think the joaquinian writing – her choices, erasures, silences, indents and symbolic additions – this work will analyze the relationship between subjectivity and her writing practice, marked by secrecy around her intimacy, discretion and the distance between the text that was written and the experience recorded by it, and, yet, its organizational structure, its possibilities of use, its respect to time (live and narrated) and its production space. Anna Joaquina’s memoirs record sets up a writing and a filing practice that kept events of her and her family daily lives and major events in the country, especially in her hometown, according to her point of view. Key-Words: Memorial, manuscript, writing practice, filing, history / Este trabalho pretende abordar o Memorial de Lembrança de Anna Joaquina da Silva Marques, escrito entre os anos de 1881 e 1930 na Cidade de Goiás, sob uma perspectiva de análise fornecida pela história da escrita e da leitura. Para tanto, a pesquisa intenta historicizar o aparecimento desse manuscrito, evidenciando suas particularidades. Inicialmente, buscar-seá compreender o Memorial em sua realidade material: de um lado, os diferentes suportes da escrita (livros, cadernos, manipulações materiais); de outro, os elementos que influíram em suas próprias condições de existência e de sentido (a carestia geral, o reaproveitamento das páginas, a escrita concisa, a provável intertextualidade). Em seguida, será analisada sua superfície textual. No esforço de pensar a escrita joaquiniana – suas escolhas, rasuras, silêncios, recuos e acréscimos simbólicos – refletir-se-á a relação entre sua subjetividade e sua prática escriturística, marcada pelo segredo em torno de sua intimidade, pela discrição e pelo distanciamento entre o texto que se escreve e a experiência registrada por ele; e, ainda, sua estrutura organizacional, suas possibilidades de uso, seu respeito ao tempo (vivido e narrado) e seu espaço de produção. O registro memorialístico de Anna Joaquina configura-se uma prática de escrita e de arquivamento, através da qual se guardou os acontecimentos acerca do seu cotidiano, de seus familiares, das principais ocorrências no país e, sobretudo, em sua cidade, segundo o seu ponto de vista.

Filing and settling of claims in insolvency proceedings Abstract The aim of the thesis was to provide a comprehensive picture of the two mutually interconnected topics: (i) classification of claims from the perspective of insolvency proceedings and (ii) filing and settling of claims in insolvency proceedings. Bankruptcy has always accompanied human societies from its very beginnings when people began to exchange goods and provide services. The importance of regulation of bankruptcy is even up with growing trade exchange. The matter stays in focus of lawyers in Czech Republic because the related case law is constantly evolving, which provides the legislator with useful inputs for amendments of the statute law. The source of the amendments of the statute law is also a change in social conditions and recent public policy efforts to make debt releaf and exemption from remaining debts admissible for poor debtors. The 1st part of the thesis is a theoretical introduction focused on the nature of insolvency proceedings (including comparison with general individual civil proceedings), subjects in insolvency proceedings and legal principles governing this procedure. In the 2nd part, I analyzed the classification of claims as the insolvency statute law distinguish them, especially with regards to determination of the...

<p>Managing documents is an integral part of computer use, and with the growing document collections of today, the importance of tools that are both flexible and efficient is becoming more evident. In many cases, the hierarchical file system used by many operating systems is also used for document management purposes. However, by using the file system for document management, restrictions and limitations such as strict hierarchical document classification and the use of non-content-related document properties are inherited. This thesis explores some of the consequences of extending the non- hierarchical media-player model to handle certain document-management tasks. In order to investigate some of these design issues, DocPlayer, a system with non-hierarchical (set-based) filing mechanisms was created that supports multi- category document categorization. This system was then analyzed in the context of document-management tasks associated with writing a thesis. The main insights for designers of document-management systems include advantages and disadvantages of multi-category document categorization.</p>

Basic Laboratory Information System (BLIS) is a joint initiative of C4G @ Georgia Tech, the Centers for Disease Control and Prevention (CDC) and Ministries of Health in several countries in Africa. The vast majority of health laboratories in Africa, engaged in routinely testing samples drawn from patients (for HIV, malaria etc.), have been using non-standardized paper logs and manual entries for keeping track of patients, test samples and results. Besides the obvious burden of tedious record-keeping, these methods increase the chances of errors due to transcription and mismatches, making it difficult to track patient history or view critical population-wide data. In 2008, PEPFAR (the United States President's Emergency Plan for AIDS Relief) together with the CDC was reauthorized with a $48 billion budget over five years to combat HIV/AIDS, tuberculosis, and malaria. The focus of PEPFAR has shifted from rapid scale-up to the quality and reliability of the clinical health programs and having an effective laboratory management system is one of its goals. C4G BLIS is a robust, customizable and easy-to-use system that keeps track of patients, samples, results, lab workflow and reports. It is meant to be an effective and sustainable enhancement to manual logs and paper-based approaches. The system is designed to work in resource-constrained laboratories with limited IT equipment and across sites with good, intermittent or no internet availability. With varied practices, workflow and terminology being followed across laboratories in various African countries, the system has been developed to enable each laboratory or country to customize and configure the system in a way that suits them best. We describe various aspects of BLIS including its flexible database schema design, configurable reports and language settings, end-user customizability and development model for rapid incorporation of user feedback. Through BLIS, we aim to demonstrate a sustainable ICT solution brought about by the early and constant involvement of the target laboratory staff and technicians, identifying their short- and long-term needs, and ensuring that the system can match these needs. We will present preliminary evaluation results from laboratories in Cameroon, Ghana, Tanzania and Uganda.
