The clock's surface is made from a constantly transforming thermo-elastic membrane that, like the holiday season itself, makes hours and minutes appear — and then disappear.
Otherwise, use a glue appropriate for use with your particular clock face surface.
When the term "biological clock" first surfaced in the 1950s, it referred to cyclical rhythms in the human body, like patterns of sleeping and activity, says Jenna Healey, a PhD candidate at Yale who is studying the history of reproductive technologies.
On the timescale of the segmentation clock, cell-surface levels of Notch are unlikely to change significantly, an idea that is implicitly assumed in the DDE model of Lewis [1], [6].
The amplitude of the oscillations in Notch concentration are small compared to the average concentration in our model, which is consistent with our earlier observation in section 2.3 that, on the timescale of the segmentation clock, cell-surface levels of Notch are unlikely to change significantly.
Health centres and clinics across the Haitian capital are filled with people of all ages as medical staff work around the clock – disinfecting surfaces and making sure dehydrated cholera patients drink oral rehydration solution every few minutes.
A specific minimization strategy has been designed with a view to improving the efficiency of specialized hardware (in terms of clock cycle and surface area).
Reconstruction algorithms require distribution of a low-jitter clock from the surface down to the digitization boards in the holes with knowledge of the overall time delay between the two clock domains.
Firefighters laid down a pipe to a nearby lake and pumped 100 gallons of water every minute, around the clock, until the surface of what is known as Fire No. 3 was a muddy expanse of charred stumps.
"There are so many variables: the cartridge has a certain tonality to it, the tone-arm will impart its own frequency spectrum, the accuracy of the drive's timing affects the way the sound proceeds, and will help it stay on clock, and the surface the turntable's mounted on affects the sound because of resonances from the surrounding environment".
