A focus group study on participatory practices in early childhood education and...
Barros, S.; Coelho, V.; Wysłowska, O.; Penderi, E.; Taelman, H.; Araújo, S.; Correia, N.; Markowska-Manista, U.; Petrogiannis, K.; Boderé, A.Participation in educational settings is a universal right of every child, consigned by the United Nations Convention on the Rights of the Child. This right encompasses the need to protect and encourage young children´s active participation and decision-making in early childhood education and care. Research Findings: This qualitative study, inspired by the Lundy model (2007), examined ECEC teachers’ (n = 25) an...
Food addiction and grazing: The role of difficulties in emotion regulation and ...
Ribeiro, A.; Sinval, J.; Félix, S.; Guimarães, C.; Machado, B. C.; Gonçalves, S.; Lourdes, M. de.; Conceição, E. M.University students are a vulnerable population to the development of disordered eating, such as food addiction (FA) and grazing. FA is an emerging concept characterized by an intense desire to eat hyper-palatable foods. Grazing is characterized by the repetitive and unplanned ingestion of food throughout a period of time. Both FA and grazing have been associated with increased scores of negative urgency (NU) a...
Children’s right to participate: The Lundy model applied to early childhood edu...
Correia, N.; Aguiar, C.; Taelman, H.; Boderé, A.; Petrogiannis, K.; Penderi, E.; Karachristos, C.; Stavropoulos, E.; Wyslowska, O.Children have the right to express their views in all matters affecting them, and to have them considered and given due weight. Children’s participation is most meaningful when rooted in children’s everyday lives, and its promotion should be encouraged from the youngest ages, especially in early childhood education and care (ecec). In this paper we apply the Lundy model of participation, widely used in policy, ...

Hydrometallurgical recycling of lithium-ion batteries by reductive leaching wit...
Vieceli, N.; Nogueira, Carlos; Guimarães, C.; Pereira, Manuel F. C.; Durão, F.; Margarido, F.ABSTRACT: The hydrometallurgical extraction of metals from spent lithium-ion batteries (LIBs) was investigated. LIBs were first dismantled and a fraction rich in the active material was obtained by physical separation, containing 95% of the initial electrode, 2% of the initial steel and 22% of plastic materials. Several reducers were tested to improve metals dissolution in the leaching step using sulphuric acid...
Portuguese consensus document for the management of alpha-1-antitrypsin deficiency
Lopes, A.P.; Mineiro, M.A.; Costa, F.; Gomes, J.; Santos, C.; Antunes, C.; Maia, D.; Melo, R.; Canotilho, M.; Magalhães, E.; Vicente, I.; Valente, C.Alpha-1-antitrypsin deficiency (AATD) is a genetic autosomal codominant disorder caused by mutations in SERPINA1 gene. It is one of the most prevalent genetic disorders, although it remains underdiagnosed. Whereas at international level there are several areas of consensus on this disorder, in Portugal, inter-hospital heterogeneity in clinical practice and resources available have been adding difficulties in re...

Recovery of lithium carbonate by acid digestion and hydrometallurgical processi...
Vieceli, N.; Nogueira, Carlos; Pereira, Manuel F. C.; Durão, F.; Guimarães, C.; Margarido, F.ABSTRACT: Lithium extraction from hard-rock ores has regained importance due to the increased demand for this metal to supply the growing battery market. Therefore, several studies have been focused on the lithium extraction from ores, however, leaching and purification steps are sparsely studied. Thus, the objective of this study was to evaluate the main factors affecting the water leaching step and the subseq...
Optimization of an innovative approach involving mechanical activation and acid...
Vieceli, N.; Nogueira, Carlos; Pereira, Manuel F. C.; Durão, F.; Guimarães, C.; Margarido, F.ABSTRACT: The recovery of lithium from hard rock minerals has received increased attention given the high demand for this element. Therefore, this study optimized an innovative process, which does not require a high-temperature calcination step, for lithium extraction from lepidolite. Mechanical activation and acid digestion were suggested as crucial process parameters, and experimental design and response-surf...
