A multielement design was used to evaluate the eects of three reinforcement conditions on the free-operant and challenging responses of two individuals with severe disabilities. Preference assessments identi®ed three stimuli that could function as reinforcers for each participant. Reinforcers were d

✦ Synopsis
The effects of various materials on aging rates of wire chambers filled with dimethylether gas were investigated. Silicone compounds and urethane polymers were observed to dramatically increase aging damage in test chambers. All other materials tested did not appear to significantly affect the measured damage rates.
