Experimental characterization of the out-of-plane performance of regular stone masonry walls, including test setups and axial load influence

Stone masonry is one of the oldest and most worldwide used building techniques. Nevertheless, the structural response of masonry structures is complex and the effective knowledge about their mechanical behaviour is still limited. This fact is particularly notorious when dealing with the description of their out-of-plane behaviour under horizontal loadings, as is the case of the earthquake action. In this context, this paper describes an experimental program, conducted in laboratory environment, aiming at characterizing the out-of-plane behaviour of traditional unreinforced stone masonry walls. In the scope of this campaign, six full-scale sacco stone masonry specimens were fully characterised regarding their most important mechanic, geometric and dynamic features and were tested resorting to two different loading techniques under three distinct vertical pre-compression states; three of the specimens were subjected to an out-of-plane surface load by means of a system of airbags and the remaining were subjected to an out-of-plane horizontal line-load at the top. From the experiments it was possible to observe that both test setups were able to globally mobilize the out-of-plane response of the walls, which presented substantial displacement capacity, with ratios of ultimate displacement to the wall thickness ranging between 26 and 45 %, as well as good energy dissipation capacity. Finally, very interesting results were also obtained from a simple analytical model used herein to compute a set of experimental-based ratios, namely between the maximum stability displacement and the wall thickness for which a mean value of about 60 % was found.

Ambivalent Islam: the identity construction of Muslims under Portuguese colonial rule

This article wishes to contribute to the study of the historical processes that have been spotting Muslim populations as favourite targets for political analysis and governance. Focusing on the Portuguese archives, civil as well as military, the article tries to uncover the most conspicuous identity representations (mainly negative or ambivalent) that members of Portuguese colonial apparatus built around Muslim communities living in African colonies, particularly in Guinea- Bissau and Mozambique. The paper shows how these culturally and politically constructed images were related to the more general strategies by which Portuguese imagined their own national identity, both as ‘European’ and as ‘coloniser’ or ‘imperial people’. The basic assumption of this article is that policies enforced in a context of interethnic and religious competition are better understood when linked to the identity strategies inherent to them. These are conceived as strategic constructions aimed at the preservation, protection and imaginary expansion of the subject, who looks for groups to be included in and out-groups to reject, exclude, aggress or eliminate. The author argues that most of the inter-ethnic relationships and conflicts, as well as the very experience of ethnicity, are born from this identity matrix.

Perspectives of Identity in Julio Cortázar’s Rayuela

My aim was to produce a dissertation, based on Rayuela, which focuses on Cortázar’s questioning of identity. With this objective in mind, I have studied some of the salient elements in the novel that relate to this topic and the subsequent, interrelated, areas of study that arose in doing so. The cities of Paris and Buenos Aires are placed in contrast within the novel and reflect a dichotomy that reflects Oliveira’s condition as a “foreigner,” (more specifically as a South American in Europe). This duality is further reflected in Cortázar’s use of gender, and the development of the notions of active and passive, and an investigation into the traditional modes of thought, symbols, and stereotypes, and an open-ended questioning of their validity. These topics are framed by a notion of Judeo-Christian History that is in many ways flawed and, as such, contrasts with a more intuitive (or “oriental”) perception of reality, which is centred in figures such as la Maga. I found many explicit references to Zen philosophy, and related oriental references, that led me to believe that this area was worthy of further investigation. Rayuela is considered a classic novel within the canon of Spanish language literature. It’s famous “tabla,” like the rules for a game between the writer and the receptor that produce alternative readings, has led to many discussions regarding the novel’s structure and form, and also created a certain amount of polemic with the use of concepts such as the “lector hembra.” Many consider Cortázar a greater short story writer than a novelist, but nevertheless this novel had a profound effect on young readers upon its publication, much to Cortázar’s surprise, and continues to attract readers, dealing as it does with issues that continue to be relevant to many people.

Regular = planeado versus irregular = espontâneo: nascimento e morte de uma relação dicotómica nos estudos históricos da forma urbana

Neste artigo analisa-se uma importante relação teórica nos estudos históricos sobre a forma urbana. Trata-se da relação que associa as formas urbanas regulares ao planeamento urbanístico e, pelo contrário, as formas urbanas irregulares à falta de planeamento urbanístico. Partindo da formulação inicial estabelecida nos textos inaugurais de história do urbanismo, procura-se verificar o impacto desta relação dicotómica na construção do conhecimento, para depois alcançar a transformação operada nas últimas décadas, que levou à sua refutação, utilizando para o efeito o contributo metodológico, teórico e conceptual de alguns estudos produzidos desde a segunda metade do século XX.

Calibração de filtros de fator de transmissão regular em espectrofotometria

A garantia de exatidão e de precisão, assim como da reprodutibilidade, da repetibilidade e da produtividade dos processos de medição, tornaram-se metas da metrologia, visando desta forma uma garantia da qualidade de produtos e serviços. A presente dissertação foi desenvolvida no âmbito de estágio curricular realizado no Departamento de Metrologia (DMET) do Instituto Português da Qualidade (IPQ). O objetivo inicial do estágio visava a participação na calibração de espectrofotómetros. Entretanto, no decorrer do estágio, também foi possível elaborar uma proposta de melhoria aos procedimentos técnicos de calibração existentes na altura, para medições de fatores de transmissão regular, com dois instrumentos de medição de elevada qualidade. Esta proposta de melhoria integra-se na busca de melhoria contínua dos processos no Laboratório de Espectrofotometria (LE), pertencente ao Laboratório Central de Metrologia (LCM) do IPQ. Visando a rastreabilidade metrológica dos resultados obtidos, foi feita a adaptação dos procedimentos existentes. Para a calibração de ambos os espectrofotómetros, utilizaram-se filtros padrão de vidro de tamanho standard (33 mm x 10 mm) e de tamanho superior ao standard (50 mm x 50 mm) certificados pelo Laboratório Primário de Espectrofotometria do Instituto Nacional de Metrologia do Reino Unido, o National Physical Laboratory (NPL). Com o objetivo de otimização de tempo, procedeu-se também à comparação entre resultados obtidos de fator de transmissão para os materiais de referência de tamanho superior, quando corrigidos de acordo com a reta de calibração obtida com filtros padrão de tamanho idêntico, e quando corrigidos de acordo com a reta de calibração obtida com filtros padrão de tamanho standard. No decurso do estágio, surgiu ainda a oportunidade de aplicar a experiência obtida ao caso prático de um filtro de opacímetro fornecido pelo LabMetro do ISQ. Assim, na presente dissertação, apresentam-se também os resultados de medição de fator de transmissão, para esse filtro, obtidos com ambos os espectrofotómetros.

What Fidelidade group should do to convey its human centric brand identity values to millennial insurance consumers

Companies are concerned in attracting and retaining Millennial consumers, especially if their relation with this target audience is weak. This happens in the insurance industry in Portugal and in Fidelidade group specifically. The aim of this study is to recommend a strategy for the insurance group to improve its relationship with these consumers, by conveying its human centric values. In order to address this goal, we developed a qualitative research. The main insight is that Millennials may perceive those values in the industry but do not associate them with insurance brands.

Assessment and management of the geomorphological heritage of Monte Pindo (NW Spain): a landscape as a symbol of identity

This study focuses on the granite mountain known as Monte Pindo (627 m above sea level) in the Autonomous Community of Galicia (NW Spain). This territory is included in the area classified as “Costa da Morte” in the “Politica de Ordenación Litoral” (POL) (Coastal Planning Policy) for the region of Galicia. This coastal unit, located between “Rías Baixas” and “Cape Fisterra” has great potential for demonstrating geological processes and its geomorphological heritage is characterized by a high degree of geodiversity of granite landforms. The main objective of our work is to assess the geomorphological heritage of the site, thus revealing its wide geodiversity. We shall analyze and highlight: its scientific value, developing an inventory of granite landforms; its educational valuel and its geotouristic potential. It must be ensured that the Administration understands that natural diversity is composed of both geodiversity and biodiversity. Only then will the sustainable management of Monte Pindo become possible by integrating natural and cultural heritage values. The goal is to ensure that Monte Pindo and its immediate surroundings become a geopark with the aim of promoting local development projects based on the conservation and valorization of its geological heritage.
