The innovative Horizon 2020 program sponsored by the European Union (EU) aims to promote and develop processes of waste integration in construction materials. However, several potential health hazards caused by building materials have been identified and, there-fore, there is an ongoing need to develop new recycling methods for hazardous wastes and effi-cient barriers in order to prevent toxic releases from the new construction solutions with wastes. This paper presents an overview that focus on two main aspects: the identification of the health risks related to radioactivity and heavy metals present in building materials and identification of these toxic substances in new construction solutions that contain recycled wastes. Different waste materials were selected and distinct methodologies of toxicity evaluation are presented to analyse the potential hazardous, the feasibility of using those wastes and the achievement of op-timal construction solutions involving wastes. ...

This paper gives a short overview of waferlevel chip-scale packaging technology and analyses its added value in the packaging of RF ICs. Particularly, the possibilities of substrate crosstalk suppression by substrate thinning and trenching together with embedding of rf passives (inductors, antennas) are addressed. The Shellcasetype wafer-level packaging solution is used as a study case presenting its fabrication aspects and its potential for RF IC packaging. ; Philips Semiconductors and Philips Research, Fundação para a Ciência e Tecnologia (FCT) - (SFRH/BD/4717/2001, POCTI/ESE/38468/2001), European Union under FP5 for the project Blue Whale ...

Natural hazards and correlated risks fill worldwide headlines raising both public and governmental concern. Though only major impacts reach the national headlines, locally many regions are already experiencing hands-on the effects of climate change by means of droughts, heatwaves, floods, forest fires, among others. The loss of lives and the considerable cost to the public revenue led to the decree of new representative offices and branches of crisis and civil protection. Facing a new public and scientific information demand for new data and above all solutions for such pertinent issues, the Polytechnic of Tomar proposes CLIMRisk 'Climate change adaptation measures in the management of natural and environmental risks' as a starting point to a new integrated line of research where all variables alike will be addressed, studied and interpreted in a geographical database (geodatabase). The consortium encompasses both in scientific research relevance and geographical coverage the institutions: Polytechnics of Tomar, Leiria and Castelo Branco; the Municipalities of Our´em and Ferreira do Zˆezere; and the Civil Protection and Forestry bureaus. The CLIMRisk project focuses on a specific transitional area (NUTS II), strategically located between the southern plains and the northern mountainous area, which intrinsically experiences the influence of the complete set of risks characteristic to both regions. Building upon the published research and the technical ability of the created consortium, CLIMRisk proposes the integrated study of climate, coastal areas, rivers, forestry, and biological variables, associated risks, thus building upon the created knowledgebase to propose useable tailor made adaptation measures. The outputs of the project clearly benefit the scientific community and inherent educational mainstreaming, whereas directly targeting organizations dealing with the general public, and environmental education. Furthermore, is of utmost relevance for policymakers, decision-makers, and stakeholders, as a valuable tool in developing suitable adaptation measures, which hopefully will reduce their harmful effects at a regional scale. ; FCT - Fundação para a Ciência e a Tecnologia ; info:eu-repo/semantics/publishedVersion

En el año 2013 el Consejo Latinoamericano de Ciencias Sociales organizó el concurso "Estudios sobre políticas públicas en América Latina y el Caribe. Democracia, ciudadanía y justicia social" con el fin de apoyar el desarrollo de investigaciones que permitan impactar en forma más directa en los ámbitos de intervención social y favorecer el diálogo entre las ciencias sociales y las políticas públicas. En el marco de la misma iniciativa, fue organizado este libro que contiene una selección de artículos elaborados en dicho concurso durante el segundo semestre de 2013. Se espera que los análisis que aquí se presentan dialoguen con los debates y las orientaciones de política en la coyuntura actual, y constituyan aportes para quienes se desempeñan en los ámbitos públicos relacionados con el tema de este libro.
