Some interesting phenomena are found including for instance, period-doubling bifurcation, antimonotonicity (i.e. the concurrent creation and annihilation of periodic orbits) and chaos while monitoring the system parameters.
For instance, periods of irritability can be part of normal development in young children and adolescents (Pataki and Carlson 2013), so irritability on its own may not indicate any underlying disease process.
For instance, periods of rest in flies correspond to increased threshold for arousal by mechanical stimuli, and were responsive to stimulants and hypnotics, as well as to prior lack of rest/sleep.
The "and so on" tries to make it all-inclusive, but there is no verb to make it a sentence -- and yet in this instance a period is put at the end.
This is, for instance, the period of the electrification of the households.
In the image processing, for instance, the period is the execution time needed to process one image.
Some writers – for instance, middle-period Lloyd-Webber – toied to solve the speech-song shifts by through-composing shows, but this merely introduces the new artifice of people singing bald exposition ("I am his brother") or banality ("Will you want milk with that?") at each other.
For instance, long-period ocean waves called Kelvin waves, which operate on the same time scale as El Niños, could also be a factor.
In most instances, 24-72h period was employed to determine these effects, which will have been days to weeks if similar effects were to be determined in animals.
With internal customers being bound to support processes, the number of instances per period can be seen as independent from quality and time as long as critical performance thresholds are not violated.
