In this study, the effects of the main mechanical milling parameters: milling time, process control agent (PCA), ball to powder ratio (BPR) and milling speed in the planetary ball milling of nanocrystalline Al 2024 powder were optimized by the Taguchi method.
The current investigation has dual purpose; firstly, it aims to produce fine particle-sized minerals with increased specific surface area in the presence of sodium chloride as grinding agent via ball milling.
Results indicated ignition time as a function of initial particle size of Ni, process control agent, and ball-to-powder ratio.
To evaluate infants' intuition regarding what other people value, researchers showed them videos in which an agent (red bouncing ball) decides whether it's worth the effort to leap over an obstacle to reach a goal (blue cartoon character).
With as many as 10 applicants for every lot, the company put numbered balls into a fishbowl, then had an agent draw the balls at random, to decide who would be allowed to buy the home sites.
One of the black agents receives the oblong ball from one of the white agents and tumbles awkwardly, and they all laugh at his pratfall.
Urging the journalist to bet on the no-balls, the agent claimed: "My guy in India, he makes £40,000, £50,000 each ball".
He asked Agent Fuller about the ball bearings.
And although children are aware that they are the active agent in kicking the ball and riding the bicycle, it is not always clear whether they are cuddling the toy or whether the toy is cuddling them; touching becomes interactive.
The front office felt uncomfortable asking Hill, a pending free agent, to take the ball.
