On the passage of time: Temporal differences in video-mediated and face-to-face interaction

This paper examines team work over time in video-mediated non-collocated and traditional face-to-face same-room teams. In a longitudinal between-groups design, 22 three-person teams were tested in 4 1-h test sessions at 2-week intervals. A paper-folding task was designed for the experiment that had the potential to induce differences in team...

Amino acid-catalyzed conversion of citral: Cis-trans isomerization and its conversion into 6-methyl-5-hepten-2-one and acetaldehyde

Under alkaline conditions, amino acids or proteins catalyze the deacetylation of citral, a major aroma component, resulting in methylheptenone and acetaldehyde formation. 3-Hydroxycitronellal is an intermediate in this reaction. Amino acids also catalyze the cis-trans isomerization of the pure isomers of citral, geranial, and neral. Most likely...
