... Processing of solid waste involves quantification of the performance of separation devices. The concept of efficiency is difficult to define. The literature frequently makes use of recovery, but that can be very misleading, since purity is left unaccounted for. Ideally, one should like...

..., few tests of performance have been conducted and no standard test methods have been published. This paper lists and describes some of the physical criteria and laboratory and field tests needed to determine performance, including efficiency, selectivity, and injury sustained by captured animals...

... The true costs of pesticide application are still ill-defined and frequently misconceived, despite the fact that they form a large, and growing, proportion of the costs of crop protection. Increased efficiency in the application of pesticides is vital for the achievement of maximum economic...
