Abstract:
In this article, existing terminology concerning occupational performance is reviewed. The authors conclude that the occupational therapy terminology available is insufficient to describe levels of complexity in the performance of an activity. Concepts are suggested to describe the different aspects of an activity, namely operations, single actions, generated actions, action sequences, and simultaneous actions. The suggested concepts are not intended to replace, but to supplement existing terminology.

Factors Affecting Activity Coefficient
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a decrease in the...
