Comparative research
Although comparative research flourishes within this discipline, methodological problems persist. After defining comparative research, this article outlines some of its central problems, including: (1) case selection, unit, level and scale of analysis; (2) construct equivalence; (3) variable or case orientation; and (4) causality.
A comparative study of comminution in rotary and vibratory ball mills
A comparative study of the comminution in rotary and vibratory ball mills using sodium chloride is presented. The many advantages of vibratory over rotary ball milling are outlined and it is shown experimentally that the rate and extent of grinding is higher for the vibratory ball mill. It is further shown that fine particles re-aggregate in ...
