This paper presents a new phase stability method that is applicable when repeated phase behavior calculations are needed as it is the case with multiphase fluid flow compositional simulation in upstream petroleum engineering.
During the CH4/CO2 redox process, the repeated phase separation occurred over LFA-900 and LFA-1000 accompanied by the appearance of metallic Fe and FeAl2O4, which resulted in serious CH4 pyrolysis.
Any viewer of the popular program Ancient Aliens will recognize the oft repeated phase "What if.... ?" or "Could it be that...?" used to infer reality.
In older mice, repeated phase advances can increase mortality, an effect not seen with phase delays [44].
This finding suggests that repeated phase advances negatively impact learning and memory well past the point of readjustment to the current time photoperiod.
Thus, repeated phase advances, such as those seen in experimental jet lag, may result in more pronounced deficits in the ability to re-establish the appropriate phase relationship between the environment and internal physiology.
We intentionally chose repeated phase advances for this initial characterization because these manipulations require significantly more time for behavioral and physiological re-entrainment than phase delays [3], [42], [44], [45], [46].
Upon detection of mating, females were maintained on either control lighting conditions (12 light:12 dark, lights on at 0700h) or exposed to repeated phase shifts throughout gestation and for 1 week after birth.
Whether or not reductions in neurogenesis persist one month after recovery from repeated phase shifts, suggesting a contribution to these continued deficits, represents an important question for future investigation.
Notably, previous work has shown that repeated phase shifting following the acquisition of a passive avoidance task impairs retention, suggesting that circadian disruption can also retrogressively impair memory consolidation [14].
