Background/Objectives: The COVID-19 pandemic profoundly affected university students globally, exacerbating their already existing academic stress. This study investigates how the first lockdown (March-July 2020) differently impacted Portuguese, Spanish, and Brazilian students' perceived stress, personal well-being, engagement, performance. Methods: An online survey collected responses from 1081 (78.17% female; Mage = 25.43 years, SD 9.27). Qualitative data on stressors were analyzed using...
Sixteenth-century mural paintings of Nossa Senhora das Neves in Vilar de Perdizes (Galicia—North Portugal Euroregion) were analysed. An iconographic study has allowed us to understand the meaning seven scenes that constitute painting. X-ray fluorescence (XRF) and Raman spectroscopies determined compounds used this painting, both original later repaintings. The black paint was bone black. Hydroxyapatite characteristic bands those associated phosphates have been identified. White lime as white...
The main driving forces concerning the use of pre-primed automotive sheet are corrosion protection increase and cost reduction during vehicle manufacturing.In this work, behaviour two conductive primers, codified by 1 2, was studied compared with that a conventional electrophoretic primer.Primer is an organic zinc rich silicate low thickness (near 4 µm) primer 2 very thin water based filled graphite.These primers were applied on electrogalvanized, hot dip galvanized galvannealed steel...
Potentially toxic elements are mobilized in aquatic systems solution or bounded to colloids of different sizes, which may include nanometer particles. The present work studies the distribution (Al, Fe, Zn, Mn, Co, Cd, Ni, Cu, and As) between small (<0.20 μm) larger (0.45–0.20 waters sources a world class metallogenic province (Iberian Pyrite Belt), including acid mine waters. Syringe filters with pore-size ratings 0.20 μm 0.45 have been used assess transport fate these potentially...
Contamination by acid drainage is an environmental problem in mineralized regions, especially the surroundings of sulphide mines. The water rock interaction process involves oxidative dissolution sulphides, naturally or mining activity, that generates acidity which, turn, produces sulfate, and pollution sulphide-hosted metals. particular geology Iberian Pyrite Belt (IPB) southwestern Peninsula creates ideal conditions for such contamination. Different types were sampled at 28 locations...
