Summary: This study uses machine learning algorithms to predict pyrolytic product yields based on biomass physicochemical characteristics and pyrolysis conditions. The Random Forest (RF) algorithm is found to be the best modeling algorithm, particularly for predicting bio-oil yields. Moisture content, carbon content, and final heating temperature are identified as the most important factors in predicting pyrolysis product yields, with biomass characteristics being more influential than pyrolysis conditions. The findings also highlight the positive effect of carbon content on bio-oil yields and the negative effect of final temperature on biochar yields. This work provides valuable insights for optimizing the process of pyrolytic product yields in engineering applications.

Summary: Carbonyl compounds can be formed during craft beer production process, affecting sensory properties and posing a risk to health due to their toxicity. This study quantified 15 carbonyl compounds in craft beers, both in free and bound forms, using hydrolysis and derivatization reactions. The presence of acrolein, benzaldehyde, heptanal, and formaldehyde in craft beers suggests potential undesirable flavors. Frequent consumption of craft beers containing these carbonyl compounds could be harmful to health.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
