Effect of peel ply-induced surface roughness and wettability on the adhesive bo...

Adhesive joint failure remains a critical limitation in the manufacturing of large wind turbine blades, where reliable and reproducible surface preparation methods are required at an industrial scale. This study systematically evaluates the effect of peel ply-induced surface morphology and chemistry on the adhesion performance of glass fiber-reinforced polymer (GFRP) laminates, explicitly examining the relation...

Prognóstico Psiquiátrico aos 3 e 6 Meses em Sobreviventes por Infeção SARS-CoV-...

Introdução: Nos sobreviventes de infeção grave por SARS-CoV-2 as sequelas psiquiátricas a médio e longo prazo são expectáveis. Estudos portugueses a incidirem nesta temática são parcos. O nosso objectivo foi fazer avaliação da prevalência a médio prazo e preditores de doenças psiquiátricas nos sobreviventes COVID-19. Métodos: Estudo longitudinal e prospectivo com sobreviventes de infeção grave por SARS-CoV-2, a...

STEM AND STEAM EDUCATION IN BASIC EDUCATION: CHALLENGES AND POTENTIAL IN TEACHE...

This research explores the implementation of STEM and STEAM approaches in primary education, analysing teachers' perceptions and the challenges inherent in their application. The aim is to understand the impact of these practices on the development of crucial skills such as critical thinking, creativity and problem-solving, and to assess how teacher training can be optimised for innovative education. The study ...

Synthesis and structure elucidation of dihydro-metabolites of the synthetic cat...

Background: Synthetic cathinones are new psychoactive substances widely abused due to their psychostimulant effects. Among them, pentedrone and methylone are part of the most consumed in the USA and Europe [1]. The metabolism of synthetic cathinones is well described in literature. Methylone can undergo, for instance, N-demethylation, O-demethylation, N-oxidation, and β-keto reduction to afford the metabolites ...

Quality of Life 3 and 6 Months in SARS-CoV-2 Survivors Treated in an Advanced R...

Introduction: Mid- and long-term health effects of SARS-CoV-2 infection have been increasingly recognised. Our goal was to evaluate health-related quality of life in critically ill patients,treated in a non-ICU setting, and associated factors with poor outcomes. Methods: Health-related quality of life in SARS-CoV-2 survivorswas evaluated 3 and 6 months after discharge, using St. George's Respiratory Questionnai...

Halochromic silk fabric as a reversible pH-sensor based on a novel 2-aminoimida...

Textiles are important components for the development of lightweight and flexible displays useful in smart materials. In particular, halochromic textiles are fibrous materials with a color-changing ability triggered by pH variations mainly based on pH-sensitive dye molecules. Recently, a novel class of 2-aminoimidazole azo dyes was developed with distinct substituent patterns. In this work, silk fabric was func...

Synergistic antimicrobial activity of silver nanoparticles with an emergent cla...

he combination of two or more agents capable of acting in synergy has been reported as a valuable tool to fight against pathogens. Silver nanoparticles (AgNPs) present a strong antimicrobial action, although their cytotoxicity for healthy cells at active concentrations is a major concern. Azoimidazole moieties exhibit interesting bioactivities, including antimicrobial activity. In this work, a class of recently...

CConjugating azoimidazoles and gold nanoparticles for a synergistic antimicrobi...

Performance evaluation of the BioBall device for wrist rehabilitation in adults...

The BioBall device, developed for wrist function rehabilitation, allows the execution of movements with a greater level of control. A component was added to make it possible to read the range of motion of the patient’s wrist. Thus, this project came up intending to evaluate the performance and suitability of the BioBall device for wrist function rehabilitation. To this end, a technical evaluation was performed ...

The Mississippian Toca da Moura-Cabrela Basin (SW Ossa-Morena Zone, Portugal): ...

Introduction and Geological context The Iberian Massif is the most southwestern domain of European Variscides, displaying an internal organization that allows to identify several palaeogeographic zones, among which the Ossa-Morena Zone (OMZ) that is included in the hinterland domains of this Massif. The Carboniferous sedimentation in the hinterland is restricted to small basins, controlled by the tectonic setti...
