Puchali Karvat, Malavika (author)Dietary habits refer to the set of choices or decisions one makes regarding the foods consumed. They include choices and decisions on what to eat when to eat, how much to eat, and where to eat. Taste preferences, food diversity, frequency of meal consumption, portion sizes, snacking behavior, and meal skipping all have an impact on this....master thesis 2021

Kosari, A. (author)For many decades, corrosion and corrosion inhibition of high-strength aluminium alloys have been studied indirectly and through traditional and separately performed electrochemical, spectroscopic and microscopic techniques. These approaches employed to date commonly lack sufficient lateral and time resolution to unravel early-stage events which...doctoral thesis 2021

Allaart, M.T. (author), Stouten, G.R. (author), Sousa, Diana Z. (author), Kleerebezem, R. (author)Anaerobic microbial communities can produce carboxylic acids of medium chain length (e.g., caproate, caprylate) by elongating short chain fatty acids through reversed β-oxidation. Ethanol is a common electron donor for this process. The influence of environmental conditions on the stoichiometry and kinetics of ethanol-based chain elongation...journal article 2021
