Results revealed that prior experience with the drug alone, or with fighting alone, had no effect on apomorphine-induced aggression. However, animals that(More)

In their simplest form, these actuators have performance equal to and resistance to chemical attack far superior to the recently discontinued commercial actuator around which the valve was originally designed.(More)
