Execução de túneis nas formações vulcânicas da Ilha da Madeira: o caso do túnel 1 da nova ligação Vasco Gil-Fundoa à cota 500

Este trabalho pretende contribuir para um melhor conhecimento ao nível da execução de túneis em formações vulcânicas, mais especificamente na Ilha da Madeira, visto esta região ter sido nos últimos anos palco da construção de inúmeros túneis rodoviários, que forneceram novos dados, experiencias e metodologias na execução de túneis em maciços vulcânicos. Assim sendo, esta tese foca inicialmente a geologia da Ilha da Madeira com o objectivo de dar a conhecer as características litológicas das rochas que compõem os maciços vulcânicos assim como é feita uma abordagem à história e evolução dos túneis existentes na região, com realce para os vários tipos de túneis executados e para os acidentes mais comuns que acontecem durante a escavação neste tipo de maciços. Depois são abordados os estudos geológicos e geotécnicos que são indispensáveis antes do inicio da execução dos túneis e também os métodos de escavação utilizados em maciços vulcânicos. É ainda abordado o estudo das vibrações causadas pelo uso de explosivos na escavação de túneis visto ser o método mais usado na região. Por fim é relatado o acompanhamento realizado durante a execução de um túnel na Ilha da Madeira, com particular destaque ao estudo das vibrações causadas devido à detonação de explosivos.

Metodologia BIM: uma nova abordagem, uma nova esperança

A metodologia BIM (Building Information Modeling), tem vindo a ganhar grande importância na indústria da AEC (Arquitetura, Engenharia e Construção). Este conceito introduz alterações muito significativas na forma como atualmente se aborda a conceção, construção e manutenção de edifícios. Apesar da emergente utilização, não existem neste momento normas de boas práticas para a sua implementação em Portugal. O BIM tem como princípios a integração das fases do processo construtivo, a integração e trabalho colaborativo de todas as especialidades envolvidas na fase de projeto, sendo apoiada por aplicações de visualização tridimensional. O grande potencial do conceito BIM está também na normalização da informação, sendo suportada entre outros aspetos na normalização da forma como se devem modelar os objetos. Assente nesta base são várias as potencialidades que daqui decorrem. No âmbito desta dissertação pretende-se abordar e aplicar a metodologia BIM ao projeto de estruturas e de especialidades que foi previamente elaborado segundo a metodologia tradicional (CAD 2D). Pretende-se, clarificar a metodologia BIM e avaliar algumas das ferramentas computacionais disponíveis no mercado. O caso de estudo da presente dissertação, permitiu identificar algumas dificuldades e falhas existentes nos projetos a 2D, o que não acontece no caso da metodologia BIM.

Percepções de maturidade em gerenciamento de projetos à luz da nova gestão pública: uma investigação com gestores das secretarias estaduais do Rio Grande do Norte

This study aimed to measure the perception of maturity project management of state boards of Rio Grande do Norte by the perception of its managers. Argues that project management has been highlighted as a critical factor for the success of any organization, because the projects are directly related to the set of activities that result in organizational innovation as products, services and processes and the improvement of project management is directly aligned with the main pillars of the New Public Management. Methodologically, this is a quantitative research of a descriptive nature in which 161 forms were applied with coordinators and subcoordinators of state departments of Rio Grande do Norte, culminating in a sampling error of less than 6% to 95% confidence according to the procedures finite sampling. The process of tabulation and analysis was done using the package Statistical Package for Social Sciences - SPSS 18.0 and worked with techniques such as mean, standard deviation, frequency distributions, cluster analysis and factor analysis. The results indicate that the levels of maturity in project management in state departments of Rio Grande do Norte is below the national average and that behavioral skills are the main problem for improving management in these departments. It was possible to detect the existence of two groups of different perceptions about the management of projects, indicating, according to the managers, there are islands of excellence in project management in some sectors of the state departments. It was also observed that there are eight factors that affect maturity in project management: Planning and Control , Development of Management Skills , Project Management Environment , Acceptance of the Subject Project Management , Stimulus to Performance , Project Evaluation and Learning , Project Management Office and Visibility of Project Managers . It concludes that the project management in state departments of Rio Grande do Norte has no satisfactory levels of maturity in project management, affecting the levels of efficiency and effectiveness of the state apparatus, which shows that some of the assumptions that guide the New Public Management are not getting the levels of excellence nailed by this management model

Treinamento e desenvolvimento de pessoas e a nova gestão pública : o caso do projeto Formação de tecnólogos em gestão pública do governo do Rio Grande do Norte

This thesis aims to identify how civil servants perceive changes made inthe carrying out of their work after their taking part in the Course forTechnicians in Public Management of the Government of Rio Grande do NorteState. As for the methodological procedures, an exploratory-descriptivequantitative research has been carried out through structured questionnaires appliedto 118 civil servants from the first groups of the Course for Technicians, thusshowing a margin of error of 4.18% to 95% of confidence, according to theprocedures of finite sampling. The table processing and analysis rested uponthe Statistical Package for the Social Sciences SPSS and was carried outthrough univariate, bivariate and multivariate techniques with emphasis on thetechnique called Factor Analysis. It was possible to identify that the level ofsatisfaction of the students was high and there was a clear perception by themthat the course assisted to changes in their work. Through Factor Analysis itwas verified that the factors that may be related to changes in the work of thecivil servants are "Contribution to Society", "Efficiency andEfficacy in the Work Environment", "Applicability of Contents"and "Capacitating for Leadership". The conclusion of the studyindicates that the factors obtained are directly related to the basis of thenew public management by means of guidance toward efficiency and efficacy in aperspective of leadership, the contents of the course being thus made into newattitudes toward work which end up yielding better results for society

A verdade (des)construída: a inserção da homossexualidade na comunidade cristã Nova Esperança, em Natal

The religious plurality has been increasingly intense in Brazil, while it has served as an object of study in various fields of knowledge. In this context, this paper aims to point out the general heterogeneity among experienced growth of Protestant and evangelical denominations, especially those who claim to be inclusive by attending to human diversity, seeking to understand the relationship between religion and homosexuality. Specific objectives aim to understand the functioning and speeches produced by Comunidade Cristã Nova Esperança in Natal. The theoretical framework was seated in the works of Bento (2008), Lima (2009), Goffman (2001), Natividade (2008), Musskopf (2008), Helminiak (1998), Foucault (1997), among others. We tried to discuss the trajectory and how is the process of organization of the Comunidade Cristã Nova Esperança in Natal, the social advances that have reached homosexuals in our country, how this institution has contributed to the shift in paradigm in Christianity in respect to matters pertaining to religion and homosexuality, and the meaning of being a homosexual christian from the viewpoint perceived by social subjects living this experience

Mobilidade urbana sustentável em projetos estruturantes: analise urbanística e ambiental do corredor de transporte da Avenida Bernardo Vieira Natal/RN

The search for a sustainable urban mobility, has recast the public policy of transport and movement for all, in order to contribute to the welfare economic, social and environmental. Within this context, has as its main objective review here in the city of Natal in the state of Rio Grande Norte, the deployment of the new road infrastructure of the transport corridor of Bernardo Vieira Avenue and checking at least with regard to urban areas and environmental chosen here, as will indicators to assess sustainable urban mobility, that the theory has been well constructed, but in practice little way to apply the proposed guidelines for sustainability. To achieve this result, is initially a literature review with the principal investigators of the matter, since the concepts of indicators of sustainable urban mobility. And a second time, participating in to the case study, using the methodology of environmental awareness, through analysis photographs, notes and testimony in the study area ace to reach conclusions

Caminhos que estruturam cidades: redes técnicas de transporte sobre trilhos e a conformação intra-urbana de Natal

The railroad, from 1870 and on, becomes an usual complaining in the press s and politician elite s speeches, especially because of Natal s geographic isolation. The implantation of two railroads in the capital territory Estrada de Ferro de Natal a Nova Cruz, afterwards part of Great Western Railway Company network, and Estrada de Ferro Central do Rio Grande do Norte had serious implications in the urban environment. While railroad s structures were already consolidated, other transportation mechanisms were being implanted in the first decades of the 20th century, such as trams lines, which, by the way, was a transport modal that also used rails as a dislocation meaning. Considering these questions, we may ask: how come railroads and tramways demands, roads and buildings had influenced the internal organization of Natal? We work with the general hypothesis that the influence of technical networks, composed by tramways and railroads, over Natal s urban space happened in a diversified way, sometimes consolidating social aspects in certain areas, sometimes improving the occupation of others. The impact over the city s territory also happens in a diversified way between the buildings/railroad s complexes and the pathways. The different scale of the train in comparison to the trams velocity, size, noise level, flow, among others is also a cause to the different consequences in urban environment. The main objective of this work is to understand the role of circulation technical networks in the construction process of urban space in Natal, as a way to contribute to the urban historiography about the subject. The time frame adopted, between 1881 and 1937, marks the time path of railroads and tramways in Rio Grande do Norte: 1881 is the year of railroad s first section inauguration from Natal to São José do Mipibu as well of the railroad complex in the Republic Square in Natal; the year of 1937 marks the beginning of tramways declination process in the city. At this time railroads and tramways had to face more intensively the competition of motor vehicles. The theory reference adopted is based on concepts and analysis of authors, such as Flávio Villaça and Roberto Lobato Corrêa references to the concepts of urban structure , localization and accessibility and Gabriel Dupuy to explain the concept of urban technical networks . These references reveal the conflict of different realities in the urban universe interests and values which is an important factor about the construction of urban space. The information sources used were from two distinctive natures: primary, journals of the time studied and official government reports, and secondary, based on other works about the subject. It was also used by this study iconographic source, especially images from the data base of the research group História da Cidade, do Território e do Urbanismo .
