Over the years, our research group developed dehydrodipeptides N-capped with aromatic moieties as protease-resistant efficacious hydrogelators, affording self-assembled hydrogels at low (critical) concentrations. Dehydrotripeptides, with different dipeptide sequences and (D,L) stereochemistry, open a wider chemical space for the development of self-assembled soft nanomaterials. In this work, a small library of ...
A disseção espontânea do tronco celíaco representa uma patologia rara, cuja incidência tem vindo a aumentar nos últimos anos. O sintoma mais comum é a dor abdominal e o diagnóstico é habitualmente feito por tomografia computorizada. A etiologia da doença, a sua apresentação e evolução clínica estão ainda mal esclarecidas. Dado ser uma entidade incomum, não existem linhas orientadoras no tratamento ou seguimento...
Esta história, como quase todas, começa com um acaso. De Jul a Out, o Centro Ciência Viva da Floresta (CCVF) teve patente a exposição, “Líquenes, a beleza da simbiose” (STOL/DBio-UMinho). Nesse âmbito, convidou uma das autoras para um Café de Ciência e, “já agora”, o “Encontro com um cientista” da Escolinha Ciência Viva. Era a vez da turma P9 da EB de Proença-a-Nova (PaN) constituída por 17 crianças (4º ano) e ...

A abordagem baseada em competências é uma das tendências fortes nos A abordagem baseada em competências é uma das tendências fortes nos currículos atuais. Em Portugal, as Aprendizagens Essenciais (AE) definem explicitamente os conhecimentos, capacidades e atitudes a serem alcançados em cada ano ou ciclo de escolaridade em cada componente curricular. Esta perspetiva tem sido adotada como uma forma de promover um...
Purpose: This research investigates Portuguese manufacturing companies' Industry 4.0 (I4.0) maturity perception level and proposes an index to measure that aim. Design/methodology/approach: This study uses a survey method to gather the companies' perceptions of their I4.0 maturity level and applies subsequent exploratory factor analysis to propose a global I4.0 measurement index. Findings: The research results ...
This research investigates Portuguese manufacturing companies’ Industry 4.0 (I4.0) maturity perception level and proposes an index to measure that aim. The research results show that the most critical factors in evaluating the perception level of I4.0 Perception Maturity (IPM) are strategy, leadership, and customer experiences. The result for the Global Index was 53.50%. Hence, the global Index companies’ perce...

This paper attempts to prove that BioShock (2007), a science fiction video game set in 1960, and BioShock: Rapture (2011), the novel published in its wake which starts in 1945, present a powerful critique of the myth of the self-made man, conveyed via the depiction of the fall of Rapture. Rapture is the dystopian, underwater city created by Andrew Ryan in which both the video game and the novel take place. The ...
The competency-based learning approach arose from the Bologna signed declaration. However, a competency definition has never been easy and has been evolving and adapted over time, from indicators and learning goals to learning outcomes, which were formulated in terms of competencies. Meanwhile, the competency concept becomes discussed by pears, in particular, associating knowledge, skills, and human disposition...
