Abstract: A remediation method and system is disclosed. A plurality of conductors is installed into the subsurface to introduce electrical current to produce heat in the subsurface. One or more agents are released into the subsurface to cause or accelerate the decomposition of one or more pre-existing halogenated organic compounds and release halogen ions, improving electrode performance.

Abstract: A basketball passing machine (18) includes a basketball supply (20) which provides basketballs (48) for a basketball ejector assembly (26) which passes basketballs one-at-a-time in a controlled manner along a trajectory (70) towards a waiting player. The machine can be used with a collection net assembly (16) adjacent a backboard (6) so that basketballs from both made and missed shots are collected and directed into the basketball supply. The supply of basketballs allows the passing machine to pass basketballs to the player as fast as desired, such as every three to four seconds. Balls can be passed from the machine on demand; the pass rate, the azimuth of the trajectory, the speed of the ball and the number of balls placed in play at each position can be preprogrammed. Sensors (74, 104) are used to generate signals whenever a ball is placed in play and when a shot is made. Shooting accuracy and associated information can be displayed for a player as well as recorded for future reference.
