Influence of tailings from a sulfide mine on drainage water quality, 60 years a...
Araújo, J.F.; Albuquerque, M.T.D.; Silva, N.; Silva, R. daThe GeoMatRe project aims to find low-cost solutions for water and sediment rehabilitation using raw geomaterials, in abandoned mines of the Iberian Pyritic Belt. One of our case studies is the Caveira mine in southwestern Portugal, where large piles of mining waste, containing significant amounts of metals, record the long history of its exploitation for gold (Au) and silver (Ag). After the exhaustion of its r...

Silva, R. da; Fonseca1, R.; Araújo, J. F.; Silva, N.; Albuquerque, M.T.D.O presente trabalho, inserido no Projeto GeoMatRe, visa o levantamento das condições mais atualizadas no que toca aos parâmetros físico-químicos numa mina de drenagem ácida. Uma situação crítica que ocorre na área mineira de Caveira, em Grândola, Portugal, abandonada desde a década de 60 do século passado. O objetivo passa por analisar as condições de contaminação de Elementos Potencialmente Tóxicos (EPT) nos s...
Understanding Extreme Violent Behavior in Ultra Firms: Exploring Identity Fusio...
Silva, R. da; Fernández-Navarro, Pablo; Rosa, C.; Gonçalves, M. M.; Silva, Joana Ribeiro daThis paper explores a dialogical operationalization of identity fusion in the context of football firms. An in-depth life story interview with a longstanding member of a football firm involved in several violent episodes was qualitatively analyzed. The variety of positions of the self (I-positions) as well as the dialogical relations established by such positions were examined under themes associated with ident...
