The phrase "actively warm" is correct and usable in written English.
It can be used to describe a state of being warm in a dynamic or engaging manner, often in contexts related to temperature or emotional warmth.
Example: "The sun was actively warm on my skin as I lounged by the pool."
Alternatives: "warmly engaging" or "vibrantly warm".
On arrival, the bee passively cools until a point at which it decides to begins to actively warm itself in preparation for flight.
This active warming adds an extra energetic cost to foraging, where the amount of energy spent depends upon how much heat the bee loses through passive cooling before it starts to actively warm itself in preparation for flight.
Actively warm the patient and all transfused fluids.
For their purposes, the Croatian researchers wanted studies that used only static stretching as an exclusive warm-up; they excluded past experiments in which people stretched but also jogged or otherwise actively warmed up before their exercise session.
When appropriate, the piglet was returned to its home cage, actively warmed with a warming light.
HFNC devices supply between 30 and 60 L/min of a controlled mixture of actively warmed (32 37 °C) and humidified (up to 100% relative humidity) oxygen and air through modified nasal prongs, producing a moderate positive end-expiratory pressure (PEEP) [8].
When a bee arrives at a flower, the gross amount of energy it collects follows a decelerating gain curve (as is standard in patch foraging models [24]), whilst its gross energetic expenditure is related to the costs of travelling, foraging without actively warming itself (which we call 'passive cooling'), and foraging whilst actively warming itself ('active warming').
All patients were actively warmed using a blowing warm air.
The PRT session consisted of an initial 10 minutes during which participants actively warmed up by performing, while walking, movements of flexion, extension, and rotation of the joints to be used in the conditioning session.
If patients undergoing major procedures with long lasting anesthesia became hypothermic more often, they were probably not warmed actively as we could suspect from the active warming rate and rate of temperature monitoring of this set of patients.
Tilapia are known to actively seek warmer refuges to survive short term drops in temperature [59], [63].
