Durante o tempo em serviço, estruturas e componentes de equipamentos podem falhar e causar acidentes. Isto geralmente conduz a danos materiais podendo, ainda, causar perda de vidas humanas e danos ambientais. Frequentemente, os eventos danosos são originários de falhas de materiais e de fabricação, sobrecargas não previstas ou outros problemas oriundos do tempo de operação ou deficiência de manutenção de um componente. Neste estudo, com base numa análise de propagação de trinca superficial submetida a carregamento, se avaliou a integridade de um flange da conexão de topo de uma linha flexível, sob condições criogênicas de operação. Quando em serviço, a falha deste conector pode ocasionar interrupções na produção, dano a equipamentos e meio ambiente, bem como fatalidades em plataformas offshore de petróleo. As linhas (dutos) flexíveis utilizadas para injetar gás CO2 nos reservatórios de petróleo no país trabalham submetidas a elevadas pressões internas (da ordem de 10.000 psi), o que aumenta o risco de falha do componente. Além disto, a selagem da conexão flangeada pode falhar e provocar um vazamento de fluido gasoso, proporcionando uma queda acentuada da temperatura local e potencializando a fratura frágil do componente. O cenário proposto para o estudo foi relacionado a possível falha na vedação do anel BX, localizado entre a conexão da linha flexível e a plataforma de petróleo. A metodologia foi dividida em duas etapas: a primeira corresponde à análise global linear elástica do conector na ausência de trincas e baseada no método de elementos finitos (MEF). Na segunda etapa da análise, se introduziu uma trinca no conector na região com os maiores níveis de tensão e onde é possível realizar ensaio por líquido penetrante. Assim, o estudo se concentrou na conexão flangeada do conector, adotando como um aço com 9 por cento de níquel em sua composição química, liga ferrosa de larga aplicação em tanques de armazenagem de GNL. Se buscou avaliar a resistência à fratura do material através da associação de condições severas de carregamento, baixas temperaturas e tamanho de trinca em flanges de dutos flexíveis, conforme critério severizado da norma API 6A. Desta maneira, se espera contribuir para que a indústria offshore de petróleo tenha mais uma opção de material para ser adotado na fabricação de conectores de topo das linhas flexíveis que trabalhem em condição criogênica.
During the time in service, structures and equipment components can fail and cause accidents. This usually leads to damage and may also cause loss of human lives and environmental damages. Often, harmful events are originated from materials and manufacturing faults, unforeseen overloads or other problems arising from the operation time or component maintenance deficiencies. In this study, based on the analysis of surface crack propagation under loading, was assessed the integrity of a top connecting flange of a flexible line operation under cryogenic conditions. When in service, the failure of this connector may cause production disruptions, damages to the equipment and the environment, as well as human fatalities on offshore oil platforms. In Brazil, flexibles lines (ducts) used to inject CO2 gas in oil reservoirs work subjected to high internal pressures (of the order of 10,000 psi), which increases the risk of a component failure. Moreover, the damaged flange may cause leakage of gaseous fluid resulting in very low local temperatures and resulting in brittle fracture enhancing of the component. The scenario proposed in this study is related to a possible seal BX ring failure which is located between the flexible line connection and the oil platform. The methodology was divided into two stages: the first corresponds to the linear elastic global analysis of the connector in the absence of cracks and based on the finite element method (FEM). In the second stage of analysis, it introduced a crack on the connector in the region with the highest stress levels and where it is possible to test for penetrant. Thus, the study focused on the flange connection connector, adopting as a steel with 9 per cent nickel in its chemical composition, ferrous alloy wide application in LNG storage tanks. He sought to evaluate the fracture resistance of the material through the combination of severe loading conditions, low temperatures and 9 cracks in flanges of flexible ducts as severe criteria standard API 6A standard. Thus, it is expected to contribute to the offshore oil industry has one more material option to be adopted in the manufacture of top connectors of the flexible lines working in cryogenic condition.

Full textThe nervous system is a complex network that senses and processes information and is essential for the survival of both vertebrates and invertebrates as it is involved in behavior responses. Information within the network is transmitted through specialized cell-cell contacts, including synaptic connections. Importantly, the network is not static and is believed to change during development and learning, as well as during pathological or normal age-related decline. Studying the nervous system in vivo requires the use of animal models such as Caenorhabditis elegans. Understanding of behavior and development requires visualization and analysis of synaptic connectivity. However, existing methods are laborious and may not depend on trans-synaptic interactions, or otherwise ‘trap’ the synapses by fixing the connections, thus precluding dynamic studies. In order to study synaptic modifications, we developed a new transgenic approach for in vivo labeling of specific connections in C. elegans, called iBLINC (in vivo Biotin Labeling of INtercellular Contacts). iBLINC involves the biotinylation of an acceptor peptide (AP) by the Escherichia coli biotin ligase BirA. Both are fused to two interacting post- and pre-synaptic proteins, respectively. The biotinylated acceptor peptide fusion is detected by a monomer streptavidin fused to a fluorescent protein that is transgenically expressed and secreted into the extracellular space. The method is directional, bright and dynamic. Moreover it correlates well with electron micrograph reconstruction. Using this new technique to observe synapses, which are part of the thermosensory circuitry of C. elegans, during aging, we could conclude that the connection pattern varies with age and within a population. Changes of the number and size of the synapses were observed during aging. Some segments of the synaptic region seem to be more affected than others by the aging process. Those results were corroborated by using a GABAergic pre-synaptic marker which allowed us to visualize a decline of the vesicle number with aging. In summary, in this thesis I explained a new in vivo trans-synaptic method to visualize synapses in C. elegans. Then I demonstrated that a natural decline in the number of synapses as well as the number of vesicles occurs during aging

Recent studies in our lab have revealed the pro-apoptotic function of dapk-1 during programmed cell death. To understand how dapk-1 acts in programmed cell death, we performed structure-function analysis of dapk-1. Like its human homolog DAPk, DAPK-1 contains multiple domains including kinase domain, ankyrin repeats, and death domain. We found that kinase and death domains of DAPK-1 are required for its pro-apoptotic function. To our knowledge, this is the first evidence showing the involvement of death domain in C. elegans programmed cell death, implying the potential role of an extrinsic cell death pathway. Taking a candidate gene approach, we showed that the netrin receptor unc-5 might be the death receptor acting in the DAPK-1 mediated extrinsic cell death pathway. Other regions such as cytoskeleton binding region is dispensable and ankyrin repeats are not absolutely necessary for DAPK-1 pro-apoptotic function. This result is distinct from the previous finding that these regions are required for the apoptosis-promoting activity of human DAPk. More complicatedly, human DAPk is also known as a positive mediator of autophagy, implying the potential interplay of apoptotic and autophagic pathways. Therefore, we tried to include the autophagic genes in C. elegans programmed cell death. In this study we observed that autophagic genes such as bec-1 and unc-51 bring inhibitory effects to C. elegans programmed cell death and at least some bec-1 mediated cell deaths do not require egl-1. Moreover, from double-mutant analysis we found that in addition to developmentally regulated cell death, dapk-1 may also mediate autophagy-dependent cell death.

In recent years, the food market has been flooded with adulterated food products. However, I-MEI Foods Corporation insists on providing quality food. To support this company, people in Taiwan buy its products to boycott other dishonest food brands. In the beginning of 2016, a powerful earthquake happened in Tainan. Because of this earthquake and its aftermath, people discovered the unethical behavior of construction industry and voice their dissent against big corporations, which forces companies to face social corporate responsibility. With the society’s progression, people emphasize on public perception and self-esteem. We will be evaluating Taiwan’s biggest telecommunication company’s corporate social responsibility. To understand the correlations among various aspects of corporate social responsibility and create the research hypotheses, the study includes corporate social responsibility, brand image, perceived value, repurchase intention and literature review. Variance, regression, reliability and validity will be based on the results of the case study company consumers’ responses from the questionnaire. The research results found that: i. Social corporate responsibility and brand image are mutually beneficial toward each other. ii. Social corporate responsibility has optimistic correlation with the perceived value. iii. The brand image has positive impact on the perceived value. iv. The perceived value has positive impact on the repurchase intention. We hope that this research can be served as a reference for Corporate Social Responsibility for all enterprises in the industry, promoting corporate sustainability and ongoing concern to better the industry as well as fulfilling enterprise commitment to its society.
