To avoid overheating, the mixtures were ultra-sonicated for every 5 min by a break duration about 1 min.
In both populations, the mean break duration was approximately 4 min and was characterized by light-intensity activity (approximately 500 accelerometer counts/min).
In the diary study, one item will be used to measure recovery at work (i.e., "During my work break(s), I was able to recover sufficiently from my work"), and an additional item is used to measure work break duration, with possible answers ranging from "less than 15 minutes" to "more than 60 minutes".
In simulation, different dam-break durations, upstream flows and water levels in front of dam were considered, and these influencing factors of dam break flow were analyzed, which could be referenced in planning and designing hydropower stations.
Between blocks were breaks with durations determined by the participant.
Between blocks, they could take a break, the duration of which they themselves determined.
The experiment was slow event-related, with trials separated by long breaks whose duration was sampled from a uniform distribution between 13 and 17 seconds.
Five consecutive tests were recorded with a short break, so the duration of the examination was no more than 5 minutes per eye (the total duration being no longer than a visual field examination).
The experimental design also comprised breaks with various durations.
Different SHCC and mortar specimens were broken after different durations of chloride exposure.
The unmanned Helios prototype solar-electric aircraft, designed to operate at extremely high altitudes for long durations, broke up in mid-air and was lost in the Pacific Ocean on 26 June during a test flight from the US Navy's Pacific Missile Range Facility (PMRF) on the Hawaiian island of Kauai.
