Timing mechanisms

Internal or external defect in a plastic caused by tensile stresses below its short-time mechanical strength. 

In this approach the reviews concerned the rheology involving the linear viscoelastic behavior of plastics and how such behavior is affected by temperature. Next is to extend this knowledge to the complex behavior of crystalline plastics, and finally illustrate how experimental data were applied to a practical example of the long-time mechanical stability.

Raff I think the timing mechanism may be similar in many cell lineages where precursors divide a limited number of times and then stop and terminally differentiate. The best evidence for this is that if you inactivate p27 there are more... 

Gautier We have never done the experiment, but if you modulate the content of genomic DNA, you change the onset of the MBT. We don t know what happens as far as apoptosis is concerned. If the timing mechanism that controls apoptosis is similar to the one that controls the destruction of cyclin A, we would predict that this wouldn t change because the onset of cyclin A degradation doesn t seem to be dependent on when the MBT is taking place. 

When looking at Sinner s famous circle that describes wash performance as the result of four components - temperature, time, mechanical and chemical action, it becomes clear that with decreasing wash temperature and time, chemistry has to become all the more sophisticated.

If not previously fired by the timing mechanism for the time set (5 to 92-sec), the fuze will then function on impact (Ref 51a, p 4-74)... 

Bomb Nose Fuzes, AN-M146 are MT fuzes of the combined vane-armed, pin-initiated type. The impact element constitutes a self-destroying feature which operates only when the time setting exceeds the time of flight or in case the time mechanism fails to operate...
