Insights on the effect of water content in carburizing gas mixtures on the metal dusting corrosion of iron by El Tayeb Bentria (9904024)

“…We conduct reactive molecular dynamics simulations of multi-grain iron systems exposed to carburizing gas mixtures to investigate the effect of water content on metal dusting corrosion. To simulate carbon monoxide (CO) dissociation followed by carbon diffusion, we employ an extended-ReaxFF potential that allows accounting for both the high C atoms coordination in bulk iron as well as the lower C coordination at the iron surface and interfaces. …”

Impact of the COVID-19 lockdown on lifestyle behaviors and their association with personality among adults in Qatar: A cross-sectional study by Tamara Al-Abdi (8710488)

“…This study aimed to identify changes in adherence to the Mediterranean diet (MD) and physical activity (PA) and associations with personality during lockdown. Using a cross-sectional design, a convenient sample of 543 adults in Qatar completed an online questionnaire consisting of validated tools to measure adherence to MD (MEDAS questionnaire, score ranges 0–13), PA (IPAQ, assessing light, moderate high intensity PA) and personality (BFI-10, categorizing individuals’ personalities). …”
