Observations of Vortex Emissions from Superfluid 4He Turbulence at High Temperatures
An immersed object with high velocity oscillations causes quantum turbulence in superfluid 4He, even at very low temperatures. The continuously generated turbulence may emit vortex rings from a turbulent region. ...

Nicotine-Seeking Behavior in Rhesus Monkeys
Nicotine-seeking behavior was studied in rhesus monkeys mainly in intravenous self-administration experiments on nicotine and partly in cigarette-smoking experiments. As a result, the nicotine-seeking behavior...
