A Geostatistical approch for Mercury spatial patterns assessment in sediments i...
Mota, Natália; Fonseca, Rita; Araújo, Joana; Antunes, Margarida; Valente, Teresa; Barroso, Ana; Araújo, António; Albuquerque, TeresaMercury pollution is significant in many former mining communities worldwide, including in developing countries. Anthropic contributions to environmental Hg pollution are mostly connected to fuel fossil emissions, industrial and mining activities. Among mining operations, gold exploration contributes to the highest Hg contamination rates, given the processes, widely used in the past, of mixing Hg with the gold ...

Stream sediments pollution: A compositional baseline assessment at the Caveira ...
Araújo, Joana; Fonseca, Rita; Mota, Natália; Araújo, Alexandre; Antunes I.M.H.R.; Valente, Teresa; Barroso, Ana; Albuquerque, Maria TeresaA high concentration of Potentially Toxic Elements (PTE) can affect ecosystem health. It is therefore essential that spatial trends of pollutants are assessed and controlled. River sediment pollution is widespread in mining communities around the world, including in developing countries. This study, as part of the GeoMaTre project, restoration of water bodies impacted by mine drainage, an ongoing collaborative ...
Characterization of the relationship between semantic and structural language f...
Mota, Natália; Ribeiro, Sidarta Tollendal Gomes; Copelli, Mauro; Carrillo, Fernando; Slezak, Diego FernadezPsychiatry describes speech symptoms that are indicative of disorganized thought, but measuring them is not easy. With natural language processing tools, it is possible to quantify psychiatric symptoms. Graph representations of word trajectories and semantic incoherence have independently been shown to predict the Schizophrenia diagnosis. Both analyses assess thought organization through speech, but the relatio...
