Ethnopharmacological relevance Thymus × citriodorus (Pers.) Schreb. is an interspecific hybrid between Thymus pulegioides and Thymus vulgaris, known for its pharmacological activities as diaphoretic, deodorant, antiseptic and disinfectant, the last mostly related with its antimicrobial activity. The folk use of other extracts, as hydrolates, have also been disseminated, as regulators of oily skin with anti-acne...
European cities have made significant progress over the last decades towards clean air. Despite this progress, several cities are still facing acute air pollution episodes, with various urban areas frequently exceeding air quality levels allowed by the European legal standards and WHO guidelines. In this paper, six European cities/ regions (Bristol, UK; Amsterdam, NL; Sosnowiec, PL; Ljubljana, SI; Aveiro, PT; L...
The presence of emerging contaminants has been disclosed in literature concerning sanitary landfill leachate (SLL) characteristics and toxicity [1,2]. Among the emerging contaminants identified, bisphenol A, an endocrine disruptor, and methiocarb, a pesticide, stand-out due to the relatively high concentrations detected in SLL [3,4]. In this study, the electrochemical degradation of bisphenol A and methiocarb, ...

INTRODUCTION Portuguese forensic law determines that all the mortal victims of traffic accidents must be subjected to a forensic autopsy. In this particular case, a traffic accident with minor injury lead to unbalance a previous tumoral pathology with an unusual location (...)
O uso de adjuvantes redutores de água na produção do betão tem sido um dos precursores do desenvolvimento sustentável deste material de construção. Contudo, apesar de atualmente ser comum a utilização dos adjuvantes no betão, ainda existe grande falta de conhecimento acerca dos fatores que influenciam a compatibilidade cimento-adjuvante. Torna-se então importante desenvolver procedimentos de avaliação da compat...
In spite of the widespread use of superplasticizers, it is still not possible to anticipate the compatibility between these materials and a specific cement. Such lack of knowledge does not restrain the use of admixtures in concrete, but it makes it harder to optimise mixtures and can lead to an unexpected behaviour. Therefore, in order to contribute to the on-going discussion concerning the cement-superplastici...
Os SMAS de Oeiras e Amadora, adiante designados por SMASOA, registam todas as intervenções efetuadas nas redes de águas e saneamento em Ordens de Serviço (O.S.), contribuindo para a construção de um histórico robusto e de qualidade que suporte de forma sustentada a estratégia da entidade. Inicialmente a recolha era efetuada apenas com objetivos administrativos e financeiros, tendo evoluído ao longo dos anos, nã...
Neste estudo foi avaliada a compatibilidade entre três cimentos e cinco adjuvantes, todos produtos comerciais. Os cimentos e os adjuvantes foram selecionados por apresentarem características químicas e físicas distintas para que a avaliação das pastas, com eles produzidas, permitisse determinar quais as propriedades que mais influenciam a compatibilidade entre ambos. Os resultados permitiram identificar alguns ...
