The mechanism of ice nucleation to form Type 2 PSCs is important for controlling the ice particle size and hence the possible dehydration in the polar winter stratosphere.This paper probes heterogeneous ice nucleation on sulfuric acid tetrahydrate (SAT).Laboratory Strips experiments were performed using a thin-film, high-vacuum apparatus in which t

Laboratory research has long demonstrated the disruptive effects of background sound to task performance yet the real-world implications of such effects are less well known.We report two experiments that demonstrate the importance of the role of rehearsal to a novel call center-type task.In Experiment 1, performance of a novel train Black Series Se
