In other words, not only did the time outside, in the absence of artificial light and alarm clocks, make it easier for people to fall asleep, it made it easier for them to wake up: the subjects' sleep rhythms would start preparing for wake-up just after sunrise, so that by the time they got up, they were far more awake than they would have otherwise been.
The absence of artificial stochastic model constraints permitted exposing the dynamic connectivity between the identified components.
Gels were masticated instrumentally in the presence or absence of artificial saliva to prepare model bolus.
The exact location of the measurements points was decided in situ by their accessibility and the absence of artificial sources, especially near the residential areas.
Direct electron transfer in the absence of artificial electron mediators is achieved at a potential of −0.4 V vs. SHE under neutral conditions.
Because of the absence of artificial watering, spraying pesticides and fertilizing, forest (mountain) tea usually is better adapted ecologically and environmentally and is of better quality, has more abundant minerals, and a stronger fragrance and taste, compared with tableland teas.
Such a low success rate is probably a result of the stringent paleointensity selection criteria, as well as the absence of artificial pre-selection of samples suitable for paleointensity experiments.
Model bolus was prepared through instrumental mastication using a mechanical simulator to mimic the action of the human jaw in the presence or absence of artificial saliva and was subjected to dynamic viscoelasticity measurements to investigate the rheological properties.
