Despite improvements over the years, accidents continue to be a scourge in the construction sector, leading to an increase in the number of journal articles addressing the issue, in an attempt to help construction industry to increase safety performance [1]. This paper aims to, helping construction industry and particulary tunneling community, describe the Portuguese approach to most typical health and safety problems in underground excavations performed with the Sequential Excavation Method (SEM). The article will address various topics, from safety management and organizational practices, to collective and personal protection equipment, to emergency planning. nt problems in safety and health matters are similar to several other countries, the paper will expose a compilation of Portuguese best practices used to solve that problems. This enunciation of best practices describes experience from most important and recognized Project Owners and Contractors in Portugal. In a second phase it will be analysed Portuguese weaknesses, identifying preventive measures, and their comparative importance, that should be adopted in Portugal in order to reduce accidents and health diseases.

The present study aimed to characterize the extracts prepared from Pimpinella anisum L. (anise) and Coriandrum sativum L. (coriander) (Apiaceae plants) seeds in terms of phenolic composition, and to correlate the obtained profiles with the antioxidant activity. Anise gave the highest abundance in phenolic compounds (42.09± 0.11 mg/g extract), mainly flavonoids (28.08±0.17 mg/g extract) and phenolic acids (14.01±0.06 mg/g extract), and also the highest antioxidant potential, accessed for the ability to inhibit lipid peroxidation and -carotene bleaching, reducing power and free radical scavenger activity. Apigenin and luteolin derivatives, as also caffeoylquinic acid derivatives appear to be directly related with the higher in vitro antioxidant potential of the anise extract.. In contrast, the weak antioxidant potential of coriander seems to be due to their lower abundance in phenolic compounds (2.24±0.01 mg/g extract). Further studies are necessary to evaluate the in vivo antioxidant potential of the tested extracts, but the performed in vitro experiments highlight them as potential health promoters.

(Excerto) A mediação social é uma prática em expansão na sociedade atual. Embora tenha surgido no continente americano há algumas décadas, é hoje revisitada e expandida como uma modalidade de intervenção social importante para assegurar a integração de populações vulneráveis, contribuir para a melhoria da qualidade de vida e a convivência cidadã intercultural e promover uma nova cultura de cidadania e de paz. A mediação social é atualmente reconhecida e implementada nos diversos países e continentes, como um procedimento de gestão positiva e pacífica de conflitos e como um modo de regulação social, com uma dupla função: ‘regular conflitos’ e ‘fazer sociedade’ (Briant & Palau, 1999). É um procedimento que promove a restituição dos laços sociais através da facilitação da comunicação, do diálogo e do reconhecimento do outro, afirmando-se pelos seus procedimentos, princípios e métodos como ‘uma justiça doce’ (Six,1990), ‘pedagogia do laço social’ (Corbo Zabatel, 2007) ou ‘ateliês silenciosos de democracia’ (Faget, 2010).
