Bacterial growth follows simple laws in constant conditions.
The benefits of non-stationary drying with respect to that performed in constant conditions were assessed.
In constant conditions, there is a neat cycle in which nitrogen dioxide (NO2) helps to form ozone and nitric oxide helps to break it apart.
In order to assess the accuracy of the measurement in constant conditions, in 2014 the track section without any field obstacles was chosen.
For experiments in constant conditions, nematodes where kept at a constant temperature (15°C, 18°C or 25°C) under constant darkness.
Several lines of evidence indicate that maximal increases in positive masking occur around the onset of the night phase, even in constant conditions [33].
In constant conditions, ultradian cycles of activity/rest and sleep/wake predominated in Vipr2−/− mice, whereas WT mice displayed robust circadian rhythms of behavior.
Such clock-driven entraining agents not only prevent rhythms from damping out in constant conditions, but may also tune the phase sensitivity of the circadian system.
To test the ability of flies to maintain their circadian rhythm in constant conditions, flies were monitored in constant darkness (DD) for 9 16 days following the LD portion of the experiment (Figure 3).
These rhythms were observed in slice cultures from mice housed in LD and persisted in tissues collected from mice housed in DD, despite the behavioral arrhythmicity of ∼50% of Vipr2−/− mice in constant conditions.
There was less diurnal variation in the frequency and duration of bouts of rest/activity and sleep/wake in Vipr2−/− mice than in wild type (WT) and short "ultradian" episodes of arousal were more prominent, especially in constant conditions (DD).
