[Excerpt] The mineralogical evolution of mine waste under supergene conditions reflects complex interactions among the original paragenesis, climatic regime, environmental setting, and anthropogenic influences resulting from exploitation, beneficiation, and closure methods. This study characterizes secondary mineral assemblages formed in diverse mine waste environments, using case studies from northern to south...
RESUMO: Um conhecimento detalhado e atualizado da morfodinâmica local é fundamental para apoiar as decisões e iniciativas de gestão costeira na costa arenosa atlântica do Norte de Portugal. Nos últimos anos foram realizados levantamentos fotográficos de alta precisão com recurso a veículos aéreos não tripulados. As imagens foram processadas e foram produzidos Modelos Digitais de Superfície (MDS) e ortomosaicos ...
Due to widespread multidrug-resistant (MDR) microbes, efficient treatments for infected wounds are being exhausted, which means that there is an alarming lack of effective antibiotics to treat diabetic foot ulcers (DFU). The increasing life expectancy of the population and the growing incidence of unhealthy lifestyles is leading to a concerning rise in the number of people affected with diabetes and related com...

Sendo que a satisfação do cliente se tem vindo a tornar um ponto-chave na avaliação da qualidade e pertinência de um serviço4, o apuramento da satisfação do comprador nos diferentes locais de...
The aim of this study was to chemically characterize the water quality impacts of the 88 acid mine drainage (AMD) generating mines in the Spanish sector of the Iberian Pyrite Belt (IPB). This was necessary because the Water Framework Directive of the European Union and the hydrological plans of the Tinto, Odiel, and Piedras river basins require that water quality be improved enough to allow at least some of the...
The development of smart textiles relies in many applications on of textile-integrated sensors. Flexible piezoresistive pressure sensors have many potential applications, for instance in sports science. In this study, flexible pressure sensors are built using piezoresistive polymer film and conductive fabric. Tests using a universal testing machine show that the sensors are functional, accurate, although showin...
