The mixing of environmental air into a preexisting air current or cloud so that the environmental air becomes part of the current or cloud.

In meteorology, the mixing of environmental air into a preexisting organized air current so that the environmental air becomes part of the current; the opposite of detrainment. Entrainment of air into [..]

the taking up of river sediment into transport.

The process that activates or provides a timing cue for a biological rhythm.

To draw in and transport (as solid particles, liquid droplets, or gas) by the flow of a fluid.

The process of synchronizing a biological rhythm to an environmental stimulus. See Figure 14.1.

transporting fish out of their native ecosystem by way of water passed through a conduit, penstock or diversion at dams or irrigation canals

Describing a state of an immiscible fluid component. Minute quantities of a fluid (typically water) can be dissolved or absorbed into the oil, but excess quantities can be most harmful to equipment du [..]

 - The process whereby gasses generated in the cell carry electrolyte through the vent cap.

The trapping of smaller aquatic life in filters, sluices, etc.

the conveying of particles of water or solids from the boiler water by the steam.

Describing a state of an immiscible fluid component. Minute quantities of a fluid (typically water) can be dissolved or absorbed into the oil, but excess quantities can be most harmful to equipment due to the entrainment leaving gaps in the lubricated areas.

The loss of oil from containment when it is pulled under a boom by a strong current.

the process by which relatively slow-moving and sedentary organisms are drawn in by a suction pump
