In a recent study Sheng et al. (1995, A.I.Ch.E.J. 41 (10) 2306-2313) presented activity coefficients calculated by molecular simulation (MS) for athermal model polymer-solvent systems. Both activity coefficients of the monomeric solvent in the polymer (YT) and of the polymer in the solvent (7~) were

Recently a method was proposed by the author2 for the electrolytic determination of copper in tin-base alloys. In this method the sample was dissolved in hydrochloric and nitric acids, then phosphoric acid was added and the solution heated on the hot plate about a half hour to drive off the hydrochl
The arrival of knowledge-based systems in industrial sectors requires specific software engineering, sometimes known as knowledge engineering. A good criterion to validate a knowledge-based system is to check its consistency. In this paper, a distinction between sure and heuristic knowledge is propo
