A second study headed by Beth Biller of the University of Edinburgh went to greater depths, examining brighter and darker clouds as the planet rotated (each rotation takes four hours) and using their observations to recreate what happens at different layers of the atmosphere.
DIY ALTERNATIVES If you can't afford to lay on childcare, ask family and friends if they'll make a rotation, an hour at a time, to take responsibility -- Obviously putting the tee-totallers at the end of the evening shift and leaving out the whack jobs altogether.
At Memorial, the rotation involved 32 hours of instructional time, 18 hours of lecture and 12 hours of tutorials over approximately 4.5 weeks.
The samples were rotated at a speed of three rotations per hour to further minimize any dose inhomogeneity.
Work schedules may differ by the time of day (i.e. day, evening, night), fixed versus rotating schedules, direction of rotation, number of hours worked per week, number of consecutive days worked, number of rest days, and so on.
At the latitude of Paris, the pendulum's path would complete a full clockwise rotation every 30 hours; on the Southern Hemisphere it would rotate counterclockwise, and on the Equator it wouldn't revolve at all.
So the sky does one complete rotation every 24 hours.
At the South Pole, as the modern-day scientists confirmed, the period of rotation is 24 hours.
At the rate you gave above, the Earth would have been making a rotation every couple hours in the first case, or actually spinning BACKWARDS in the latter.
In the second study, a team led by Humberto Campins at the University of Central Florida timed its observations to take account of the asteroid's rotation every eight hours and produce a crude map of the surface.
