O aglomerado negro de cortiça expandida foi fornecido pela ISOCOR/SOFALCA. ; A integração de superfícies ajardinadas em edifícios, como coberturas e paredes verdes, pode constituir uma estratégia passiva de poupança de energia, entre outros benefícios, como se discute neste trabalho. Em primeiro lugar é apresentada uma síntese dos principais benefícios da integração das superfícies ajardinadas em edifícios. Em...
The development of new metallurgical technologies in the Iberian Peninsula during the Iron Age is well represented by the 10 gold earrings from the treasure of Pancas. This work presents a first approach to the analytical study of these earrings and contributes to the construction of a typological evolution of the Iberian earrings. The manufacture techniques and the alloys composition were studied with three co...
The use of sensors to capture disparate types of information from the environment has been increasing and they cover a wide range of applications, such as climate monitoring (e.g., seismic activity and climate), water quality monitoring, area surveillance, intelligent buildings, energy management, automotive industry and scientific purposes. Additionally, the Information Age has provided rapid and ubiquitous ac...
SAFE-PORT is a recently started project addressing the complex issue of determining the best configurations of resources for harbour and port surveillance and protection. More specifically, the main goal is to find, for any given scenario, an adequate set of configuration solutions - i.e., number and type of sensors and equipments, their locations and operating modes, the corresponding personnel and other suppo...

This work presents a research plan that aims to monitor seismo-electromagnetic signals in seismic active regions. Two effects will be considered: electromagnetic field emissions and radio broadcastings. Our study will be focused in the analysis of low magnitude earthquakes almost completely disregarded in literature. We aim to collect novel seismo-electromagnetic emission data emerging from seismic activity. We...
This paper presents a future research plan that aims to monitor Seismo-electromagnetic (SEM) phenomena in the western part of the Eurasia-Nubia plate boundary (WENP). This region has a significant tectonic activity [1] combined with relatively low electromagnetic noise levels and for that reason presents the possibility to perform high quality SEM measurements. Further, it is known that low-frequency [ultra (UL...
Este estudo teve como objectivo verificar, em crianças do pré-escolar, se há diferenças nos critérios tidos em conta pelo terapeuta da fala e pelo educador de infância na avaliação de linguagem. Através da análise da relação entre dois testes, o TALC e o QLC, verificou-se que, de uma forma geral, existe pouca relação entre os resultados dos testes aplicados por ambos os profissionais. Conclui-se que ambos os pr...
A mathematical model that combines oxygen uptake from the outside environment with oxygen consumption by oxidative reactions, in a liquid packed food during storage, was developed. The model was applied to orange juice aseptically packaged in Tetra Brik Aseptic cartons, during storage of up to 5 months at 4, 8, 20, 30, 40 and 50 °C. The parameters of the model, the oxygen mass transfer coefficient and the rate ...
In the following a new data acquisition architecture is proposed allowing high sampling rates along with a large memory data buffer. The modular design allows up to four 250 MHz, 8-bit acquisition channels to operate in an interleaved way, achieving 1 GSPS. Each channel can acquire continuously up to 3 MBytes of data (or 12 MBytes when interleaved). Since several modules can coexist in an acquisition system, pr...
