Cohesive law estimation of adhesive joints in mode II condition

The adhesive bonding technique enables both weight and complexity reduction in structures that require some joining technique to be used on account of fabrication/component shape issues. Because of this, adhesive bonding is also one of the main repair methods for metal and composite structures by the strap and scarf configurations. The availability of strength prediction techniques for adhesive joints is essential for their generalized application and it can rely on different approaches, such as mechanics of materials, conventional fracture mechanics or damage mechanics. These two last techniques depend on the measurement of the fracture toughness (GC) of materials. Within the framework of damage mechanics, a valid option is the use of Cohesive Zone Modelling (CZM) coupled with Finite Element (FE) analyses. In this work, CZM laws for adhesive joints considering three adhesives with varying ductility were estimated. The End-Notched Flexure (ENF) test geometry was selected based on overall test simplicity and results accuracy. The adhesives Araldite® AV138, Araldite® 2015 and Sikaforce® 7752 were studied between high-strength aluminium adherends. Estimation of the CZM laws was carried out by an inverse methodology based on a curve fitting procedure, which enabled a precise estimation of the adhesive joints’ behaviour. The work allowed to conclude that a unique set of shear fracture toughness (GIIC) and shear cohesive strength (ts0) exists for each specimen that accurately reproduces the adhesive layer’ behaviour. With this information, the accurate strength prediction of adhesive joints in shear is made possible by CZM.

THE ISLAMIC POLICY OF PORTUGUESE COLONIAL MOZAMBIQUE, 1960-1973

Drawing its information from different documents in Portuguese and French archives, this article examines the evolution of Portuguese colonial policies regarding Islam, focusing the special case of Mozambique. Such policies evolved from an attitude of neglect and open repression, prevalent in the early years of the colonial war, when Muslims were perceived as main supporters of the anti-colonial guerrilla in northern Mozambique, to a more nuanced approach that tried to isolate ‘African Muslims’ from foreign influences in order to align them with the Portuguese combat against the anti-colonial movement. The article analyses the latter strategy, assessing its successes and failures and the contributions made by several actors that were engaged in this achievement: the Catholic Church, the core of political power and its local ramifications in the colonies.

Obama's law : analysis of a breakthrough law on healthcare access and lessons for the Portuguese health system management

ABSTRACT - The Patient Protection and Affordable Care Act shook the foundations of the US health system, offering all Americans access to health care by changing the way the health insurance industry works. As President Obama signed the Act on 23 March 2010, he said that it stood for “the core principle that everybody should have some basic security when it comes to their health care”. Unlike the U.S., the Article 64 of the Portuguese Constitution provides, since 1976, the right to universal access to health care. However, facing a severe economic crisis, Portugal has, under the supervision of the Troika, a tight schedule to implement measures to improve the efficiency of the National Health Service. Both countries are therefore despite their different situation, in a conjuncture of reform and the use of new health management measures. The present work, using a qualitative research methodology examines the Affordable Care Act in order to describe its principles and enforcement mechanisms. In order to describe the reality in Portugal, the Portuguese health system and the measures imposed by Troika are also analyzed. The intention of this entire analysis is not only to disclose the innovative U.S. law, but to find some innovative measures that could serve health management in Portugal. Essentially we identified the Exchanges and Wellness Programs, described throughout this work, leaving also the idea of the possibility of using them in the Portuguese national health system.

The Islamic Policy of Portuguese Colonial Mozambique, 1960-1973

Drawing its information from different documents in Portuguese and French archives, this article examines the evolution of Portuguese colonial policies towards Islam, focusing on the special case of Mozambique. Such policies evolved from an attitude of neglect and open repression, prevalent in the early years of the colonial war that broke out in 1965, when Muslims were perceived as the main supporters of the anti-colonial guerrilla in northern Mozambique, to an approach that tried to isolate ‘African Muslims’ from foreign influences in order to align them with the Portuguese. The article analyses the latter strategy, assessing its successes and failures, and the contributions made by several of those who were involved.

Área 'non aedificandi' em domínio privado. História breve do interstício entre prédios em Portugal

Partindo dos dispositivos jurídicos em vigor (Código Civil e Regulamento Geral das Edificações Urbanas) e recuando até às antigas influências jurídicas (romanas e islâmicas), neste artigo procura-se perceber como os interstícios entre prédios em Portugal foram estabelecidos ao longo do tempo pela ordem jurídica. São contextualizadas e analisadas as antigas normas da almotaçaria e as normas contemporâneas, procurando perceber inovações e persistências. Por fim, realça-se a importância deste conhecimento para o estudo da forma urbana portuguesa.

Tensile stress–crack width law for steel fibre reinforced self-compacting concrete obtained from indirect (splitting) tensile tests

In this work, the fracture mode I parameters of steel fibre reinforced self-compacting concrete (SFRSCC) were derived from the numerical simulation of indirect splitting tensile tests. The combined experimental and numerical research allowed a comparison between the stress-crack width (σ - w) relationship acquired straightforwardly from direct tensile tests, and the σ - w response derived from inverse analysis of the splitting tensile tests results. For this purpose a comprehensive nonlinear 3D finite element (FE) modeling strategy was developed. A comparison between the experimental results obtained from splitting tensile tests and the corresponding FE simulations confirmed the good accuracy of the proposed strategy to derive the σ – w for these composites. It is concluded that the post-cracking tensile laws obtained from inverse analysis provided a close relationship with the ones obtained from the experimental uniaxial tensile tests.

Regímenes Internacionales y Derechos Humanos. La incidencia del sistema interamericano de protección en la legislación y jurisprudencia argentinas. International Regimes and Human Rights. The incidence of inter-American system in Argentine law and jurisprudence.

El nuevo escenario internacional produce lo que se ha dado en caracterizar como la globalización del derecho, especialmente en el ámbito de los derechos humanos. En este contexto se analiza la incidencia del Sistema Interamericano de protección de los Derechos Humanos con especial énfasis en el derecho de la información, desde la optica del derecho interno. Nos preguntamos acerca de cómo se presenta la tensión entre la lógica estatal con su rasgo de afirmación en la soberanía y monopolio en la creación de la jurisdicción doméstica, con la doctrina del derecho internacional de los derechos humanos, que consecuentemente conduce hacia una globalización jurídica de estos temas. Esto refleja un debilitamiento en el monopolio de creación y aplicación del derecho por parte de los Estados. A partir de este dato del escenario internacional buscamos determinar la incidencia de los informes de la Comisión Interamericana de Derechos Humanos y los pronunciamientos de la Corte Interamericana en materia de derecho de la información y su influencia en la jurisprudencia y creación de legislación en nuestro país. The new internacional scenario produces wtah has come to be characterized as the globalization of law, especially in the field of the human rights. In this context we analyze the impact of the Inter-American system of human Rights, whit particular emphasis on media law in domestic law
