Sentence examples for under constant darkness from inspiring English sources

These mice were screened for locomotor activity rhythms and we identified two individuals (one male and one female) that exhibited abnormal patterns of activity rhythms: a large positive phase angle under 12 h light-12 h dark (LD 12∶12) cycles and spontaneous rhythm splitting under constant darkness (DD) conditions.

To study retinal damage, Atlantic cod (Gadus morhua), Atlantic salmon (Salmo salar) and European sea bass (Dicentrarchus labrax) were previously acclimated to a control 12L:12D photoperiod with standard experimental low light intensity (0.1 W/m2, equivalent to 3.2 × 1013 photons/s/cm2) for at least 4 weeks and then kept under constant darkness (DD) for 3 days.

The longevity of kale and lettuce leaf color, chlorophyll levels, and tissue integrity, which are important contributors to the appeal of green leafy vegetables to consumers [ 29], were largely indistinguishable whether the kale and lettuce leaf samples were stored at 22°C under light/dark cycles or were stored under refrigeration in constant darkness.

In particular, we sought to examine whether kale and cabbage stored under light/dark cycles maintain their glucosinolate content longer than when stored under constant light, constant darkness, or refrigeration.
