Human exposure to persistent organic pollutants (POPs) is a certainty, even to long banned pesticides like o,p′-dichlorodiphenyltrichloroethane (o,p′-DDT), and its metabolites p,p′-dichlorodiphenyldichloroethylene (p,p′-DDE), and p,p′-dichlorodiphenyldichloroethane (p,p′-DDD). POPs are known to be particularly toxic and have been associated with endocrine-disrupting effects in several mammals, including humans even at very low doses. As environmental estrogens, they could play a critical role in carcinogenesis, such as in breast cancer. With the purpose of evaluating their effect on breast cancer biology, o,p′-DDT, p,p′-DDE, and p,p′-DDD (50–1000 nM) were tested on two human breast adenocarcinoma cell lines: MCF-7 expressing estrogen receptor (ER) α and MDA-MB-231 negative for ERα, regarding cell proliferation and viability in addition to their invasive potential. Cell proliferation and viability were not equally affected by these compounds. In MCF-7 cells, the compounds were able to decrease cell proliferation and viability. On the other hand, no evident response was observed in treated MDA-MB-231 cells. Concerning the invasive potential, the less invasive cell line, MCF-7, had its invasion potential significantly induced, while the more invasive cell line MDA-MB-231, had its invasion potential dramatically reduced in the presence of the tested compounds. Altogether, the results showed that these compounds were able to modulate several cancer-related processes, namely in breast cancer cell lines, and underline the relevance of POP exposure to the risk of cancer development and progression, unraveling distinct pathways of action of these compounds on tumor cell biology.

The goal of this project, one of the proposals of the EPS@ISEP Spring 2014, was to develop an Aquaponics System. Over recent years Aquaponics systems have received increased attention since they contribute to reduce the strain on resources within 1st and 3rd world countries. Aquaponics is the combination of Hydroponics and Aquaculture, mimicking a natural environment in order to successfully apply and enhance the understanding of natural cycles within an indoor process. Using this knowledge of natural cycles, it was possible to create a system with capabilities similar to that of a natural environment with the support of electronics, enhancing the overall efficiency of the system. The multinational team involved in the development of this system was composed of five students from five countries and fields of study. This paper describes their solution, including the overall design, the technology involved and the benefits it can bring to the current market. The team was able to design and render the Computer Aided Design (CAD) drawings of the prototype, assemble all components, successfully test the electronics and comply with the budget. Furthermore, the designed solution was supported by a product sustainability study and included a specific marketing plan. Last but not least, the students enrolled in this project obtained new multidisciplinary knowledge and increased their team work and cross-cultural communication skills.

Este estudo tem como finalidade analisar a possibilidade de implementação e integração do sistema de gestão da responsabilidade social numa empresa de engenharia e construção, de acordo com a norma NP 4469-1 (2008). Um dos objetivos deste trabalho é explorar uma das atividades fundamentais para o crescimento da economia: a construção. Esta funciona como barómetro da economia nacional, ou seja, movimenta vários setores importantes na sua cadeia de produção, contribuindo na criação de riqueza como também de emprego. Como consequência das mudanças na economia nos últimos anos, o comércio nacional transformou-se em comércio globalizado, tendo como mercado não só um país mas o mundo inteiro. As empresas veem isso como um desafio, independentemente da sua dimensão. A redução de custos e a diferenciação não podem ser a única fonte de competitividade. A recente situação de instabilidade económica mundial impulsiona as empresas a inovarem na sua imagem para com os stakeholders e, assim, garantir o seu desenvolvimento e sustentabilidade financeira. A temática da Responsabilidade Social Empresarial (RSE) surgiu da necessidade de existir um espírito empresarial responsável, ao encontro do conceito de desenvolvimento sustentável (Baylis e Smith, 2005). Apesar da ampla divulgação da noção de responsabilidade social das empresas, não se verifica, no entanto, uma definição exata da mesma, pois o tema tem sido abordado de diversas formas e tem dividido opiniões ao longo dos anos. A responsabilidade social é, assim, um fruto da gestão das organizações e das profundas críticas sociais, legais, éticas e económicas, inspiradas nos parâmetros da obtenção de valor social (Parra, 2003). A sustentabilidade revela uma mudança de paradigma do mundo empresarial, na medida em que as empresas devem adotar práticas socialmente responsáveis, que integrem de forma voluntária as preocupações ambientais, sociais e económicas no desenvolvimento das suas atividades operacionais e das suas interações com as partes interessadas.

Hard‐rock watersheds commonly exhibit complex geological bedrock and morphological features. Hydromineral resources have relevant economic value for the thermal spas industry. The present study aims to develop a groundwater vulnerability approach in Caldas da Cavaca hydromineral system (Aguiar da Beira, Central Portugal) which has a thermal tradition that dates back to the late 19th century, and contribute to a better understanding of the hydrogeological conceptual site model. In this work different layers were overlaid, generating several thematic maps to arrive at an integrated framework of several key‐sectors in Caldas da Cavaca site. Thus, to accomplish a comprehensive analysis and conceptualization of the site, a multi‐technical approach was used, such as, field and laboratory techniques, where several data was collected, like geotectonics, hydrology and hydrogeology, hydrogeomorphology, hydrogeophysical and hydrogeomechanical zoning aiming the application of the so‐called DISCO method. All these techniques were successfully performed and a groundwater vulnerability to contamination assessment, based on GOD‐S, DRASTIC‐Fm, SINTACS, SI and DISCO indexes methodology, was delineated. Geographical Information Systems (GIS) technology was on the basis to organise and integrate the geodatabases and to produce all the thematic maps. This multi‐technical approach highlights the importance of groundwater vulnerability to contamination mapping as a tool to support hydrogeological conceptualisation, contributing to better decision‐making of water resources management and sustainability.

This paper aims to analyse the birth and evolution of design with concerns over sustainability, in the context of social and civilizational changes experienced since the industrial revolution, with particular focus since the post-war period and in the context of sustainable development. It will examine several factors that influenced this design approach and that drove its evolution through different stages of maturity and complexity. It will analyse the various forms of design with environmental concerns, as well as the inclusion of other criteria in the context of sustainability, namely social ones. The aim is to settle knowledge that can allow us to draw some lessons to meet the challenges we face today.

We compare the performance of Cape Verde and Mozambique concerning financial credibility as measured by Exchange Market Pressure, an institutional feature that has often been overlooked in the literature as a relevant institution for economies. Drawing on previous research by Macedo et al. (2009), we expand their analysis and, using several definitions of “financial credibility”, all related to different angles on Exchange Market Pressure indices, we conclude that - against reasonable benchmarks in their respective regions - financial credibility has been very good for Cape Verde and fairly good for Mozambique.
