Evolução dos sistemas de falhas de borda do Rifte Potiguar com base em curvas de crescimento de falhas

The discussion about rift evolution in the Brazilian Equatorial margin during the South America-Africa breakup in the Jurassic/Cretaceous has been focused in many researches. But rift evolution based on development and growth of faults has not been well explored. In this sense, we investigated the Cretaceous Potiguar Basin in the Equatorial margin of Brazil to understand the geometry of major faults and the influence of crustal heterogeneity and preexisting structural fabric in the evolution of the basin internal architecture. Previous studies pointed out that the rift is an asymmetrical half-graben elongated along the NE-SW direction. We used 2D seismic, well logs and 3D gravity modeling to analyze four major border fault segments and determine their maximum displacement (Dmax) and length (L) ratio in the Potiguar Rift. We constrained the 3D gravity modeling with well data and the interpretation of seismic sections. The difference of the fault displacement measured in the gravity model is in the order of 10% compared to seismic and well data. The fault-growth curves allowed us to divide the faulted rift border into four main fault segments, which provide roughly similar Dmax/L ratios. Fault-growth curves suggest that a regional uniform tectonic mechanism influenced growth of the rift fault segments. The variation of the displacements along the fault segments indicates that the fault segments were formed independently during rift initiation and were linked by hard and soft linkages. The latter formed relay ramps. In the interconnection zones the Dmax/L ratios are highest due to interference of fault segment motions. We divided the evolution of the Potiguar Rift into five stages based on these ratios and correlated them with the major tectonic stages of the breakup between South America and Africa in Early Cretaceous.

Proposta de arquitetura de plataforma de apoio a terapias a crianças com PHDA

A Perturbação da Hiperatividade e Défice de Atenção (PHDA) é uma perturbação que afeta cerca de 5% das crianças a nível mundial. O seu tratamento baseia-se na medicação e exercícios comportamentais para a criança, os quais podem acarretar efeitos secundários indesejados ou ser demasiado exigentes, respetivamente. Neste contexto, o objetivo do trabalho abordado neste documento foi o desenvolvimento de uma plataforma de apoio à terapia da PHDA, incluindo o desenvolvimento de serious games para crianças com idades entre os 6 e os 12 anos baseados em exercícios comportamentais, com uma abordagem mais lúdica, no intuito de aumentar o fator motivação na execução dos exercícios. A plataforma foi designada não para substituir a terapia tradicional, mas sim complementá-la, permitindo a um clínico manter os seus utentes sobre supervisão entre consultas de rotina. Desta forma, é pretendido a elaboração de um estudo sobre a fiabilidade dos serious games como forma de providenciar aos utentes um melhor controlo sobre os seus sintomas, não recorrendo apenas à terapia tradicional. Os primeiros resultados, obtidos com uma pequena amostra, demonstram uma melhora significativa nas competências das crianças e evidenciam a eficácia e robustez da plataforma em si.

Arquitetura empresarial: um estudo de caso sobre a integração entre a plataforma moodle e o sigaa na UFRN

Atualmente, um dos aspectos da gestão da informação que se encontra em evidência é o da arquitetura empresarial, entendida como o conjunto de políticas e escolhas técnicas de padronização e integração para viabilizar as estratégias de negócios da organização. Esta pesquisa tem por objetivo analisar a integração de dois sistemas de gestão na Universidade Federal do Rio Grande do Norte (UFRN) a partir das lentes da arquitetura empresarial. A influência dessa abordagem induz a organização a desenvolver um alicerce de execução com o interesse de suportar com maior eficiência sua estratégia e obter agilidade em seus processos de negócio. A análise da integração desses dois sistemas, através de entrevistas semiestruturadas, no âmbito da UFRN possibilitou a percepção da necessidade de uma estruturação dos processos de TI a partir de uma arquitetura que favoreça um melhor alinhamento das capacidades de TI aos objetivos da organização. A ausência de um modelo operacional pode comprometer a eficiência do Sistema Integrado de Gestão das Atividades Acadêmicas (SIGAA) da UFRN na realização do seu objetivo como plataforma única de gestão das informações da universidade

O projeto de arquitetura de espaços temporários com o uso de sistema construtivo remontável: um estudo exploratório

The purpose of this research is to study the portable or reassemblable architectures, which, different from conventional architecture (whose designs are of permanent buildings), corresponds to the designing of spaces with temporary purposes. The focus of the study is the architectural design of spaces that are produced from building systems that can to be moved to different places (process of assembly / disassembly / reassembly) in order to identify the types of spaces generated and the processes used in their design / projecting. The aim is to investigate relationships between the initial project conceived based on a Reassemblable Construction System (RCS) and its application in the architectural design of professionals and students in order to contribute to the understanding of the specificities of this type of design activity. To this end it was developed the exploratory research based on multimedia methods, which includes: documentary analysis, technical visits, interviews, surveys, academic exercise and documentation by images. Although the study is not conclusive, the results indicate significant differences between the point of view of the RCS´s designers and its users (architects and architecture students) since the users demonstrated to have some difficulty to access the features provided for the first group, in particular the students. It is also demonstrated that the use of RCSs seems to change the appreciation / hierarchization of the conditions of project design, since, unlike what happens in traditional architectural design, the designers who use them seem to be more concerned with constructive issues, especially the structural elements (support and covering), instead of functionality, aesthetics and even physical characteristics of the site

Arquitetura da água - Cais palafítico da Carrasqueira

Permitindo uma forma de habitar lugares de grande relação com a água, erguem-se um pouco por todo o mundo, sobre as águas de rios, barragens e lagos estruturas palafíticas. Em Portugal, em 1964 na aldeia da Carrasqueira, extremo sul do estuário do Sado, um cais palafítico começava a ser construído por pescadores-agricultores, que ali viviam, para combater mudanças de maré e aceder tanto a água como a terra. O barco, o abrigo e o caminho são os três elementos fundamentais da arquitetura palafítica aqui encontrada, em que a qualidade da água e da terra são determinantes para o assentamento da estrutura neste local. O rio Sado define-se como o limite geográfico e paisagístico da ocupação, é gerador de características únicas que permitem o desenvolvimento de um novo tipo de habitar que surge sobretudo de uma aproximação ao local e aos materiais que dele provêm. A Carrasqueira traduz o paradigma de uma cultura em adaptação contínua às circunstâncias adversas do meio ambiente. A pouca informação sobre o cais e a unicidade construtiva encontrado na estrutura, faz com que seja de elevada pertinência o estudo, sob o ponto de vista construtivo, da arquitetura palafítica da vila piscatória da Carrasqueira, enquanto matéria mutável sensível às mudanças ambientais e espontâneas. Pretende-se clarificar e identificar as singularidades da arquitetura de expressão espontânea da Carrasqueira, intrinsecamente ligada tanto à água do rio Sado, como à terra que a limita e corporiza. Para o estudo construtivo serão elaborados:  Mapas de desenvolvimento do cais;  Um registo fotográfico das estruturas;  Desenhos, realizados originalmente no decorrer desta investigação no local, de forma a criar um maior entendimento da forma de construção entre as diferentes peças e partes de cada uma das estruturas.  Construção de uma estrutura palafítica.  Vídeo, enquanto registo das fases do trabalho prático mostra parte do trabalho desenvolvido no processo construtivo. A produção dos documentos mencionados testemunha um tipo de vida invulgar na História da Arquitetura Portuguesa. O contacto com locais, pescadores, trabalhadores e gentes da terra também ajudará a entender os sistemas construtivos utilizados, pelo conhecimento construtivo por experiência própria, e proximidade das matérias-primas; ABSTRACT: Allowing life in floodplain areas, palaffitic structures take advantage from water, and appear a bit all over the world. The stilts portray a way of living changing and giving identity to the places and population. In Portugal, 1964 year, in Carrasqueira village, located on the southwest Sado’s river, facing the river side and land, a palaffitic piers was built, to fight the tide changing and allowed the population to get as close as they could to water and reach the land easier when they were coming from the fishing activity. The continuously adaptation of lifestyle in order to follow and adjust themselves to nature shows how strong and unique this culture and people are. The boat, the shelter and the paths are the three fundamental elements used in Carrasqueira’s palaffitic architecture. Water and land, construction and nature, this beautiful balance is only possible because of the river and its qualities. Also the time roles an important paper in the process, it changes with the growing of the main materials. This investigation has the goal to study the palaffitic piers of Carrasqueira by the constructivist point of view, as a spontaneous structure that began with the available materials and was continuously changing and adjusting to fit the land, the lifestyle and the needs of the population that was living there. Clarifying and identifying the singularities of this construction is what the study wants to achieve. Maps, photography’s and intensive drawings will be making on the process. A palaffitic structure will be build and the part of the building process will be available for watch on a short-video, filmed by then. The contact with locals will probably assume the biggest part of the work in main to understand their way of thinking and the process of their work.
