Abstract Contrail cirrus account for the major share of aviation’s climate impact. Yet, links between jet fuel composition, contrail microphysics and impact remain unresolved. Here we present unique observations from two DLR-NASA aircraft campaigns that measured exhaust characteristics an Airbus A320 burning either standard fuels or low aromatic sustainable aviation blends. Our results show soo...

Abstract We use estimates of meso-scale vertical velocity and co-located cloud measurements from the second Next-Generation Aircraft Remote Sensing for Validation campaign (NARVAL2) in tropical North Atlantic to show observed impact motion on clouds. Our results not only confirm previously untested hypotheses about role dynamics being non-negligible determining cloudiness, but go further that a...

The effect of ultrasound treatments (40 kHz; 40, 50, or 60°C; 5 10 min) and thermal treatment (90°C; 30 s) on the stability parameters orange-carrot juice were evaluated. Microscopic structure, particle size distribution turbidity analyzed first day. Sedimentation cloudiness evaluated over 22 days storage at 7 25°C. Changes in microstructure disruption cell wall evidenced after 60°C/10 min. was...

According to the 2006 Montreal globally acceptable definition and classification of gastroesophageal reflux disease (GERD), this condition develops when the reflux of gastric contents causes symptoms or complications (Vakil et al., 2006). Because reflux esophagitis is defined as occurring when reflux of gastric acid into the esophagus causes mucosal breaks, erosions and/or ulcers, this conditio...
