The timekeeping element of a quartz clock consists of a ring of quartz about 2.5 inches (63.5 mm) in diameter, suspended by threads and enclosed in a heat-insulated chamber.
We review recent results showing intracellular and intercellular mechanisms that convey this robust timekeeping to a variety of circadian cell types.
The timekeeping of PPBREATHE and PPAPNEA was manually performed by a professional swimming coach who was not informed of the purpose of the study.
The intrinsic flexibility of these regions may allow them to interact with a host of binding partners in a temporally dependent manner, allowing intrinsic timekeeping of the circadian clock to be finely tuned by interactions between regulatory proteins, possibly in a tissue-specific manner.
The manic timekeeping of the designers, who will rarely commission the ateliers until days before a show, and are even then liable to change their mind several times, is discussed with a patient, nannyish indulgence.
It is thus safeguarded from those alterations of position that slightly affect the timekeeping of even the best watches.
There are guided tours from Rua São Clemente but I found the timekeeping of the guides erratic, so walked around independently.
A gripping plot had somehow permitted South Africa to rise one more time from their World Cup coffin thanks to the cruel timekeeping of Derek Bevan who, talking of plots, appeared to have lost this one entirely.
