BIOPHYSICAL PRINCIPLES OF STRUCTURE AND FUNCTION. By Fred M. Snell, Sidney Shulman, Richard P. Spencer, and Carl Moos. Reading, Mass., Addison-Wesley Publishing Co., Inc., 1965. x, 390 pp. $12.75. This book represents an ambitious attempt to simplify for the uninitiated (the jacket describes it as an introductory text), the basics of physical chemistry and thermodynamics as they are applied to ...

The operation of an industrial semi-batch reactor, in which the bulk chemical EHEC, ethyl hydroxyethyl cellulose, is produced, is studied and simulated. In the reactor a strongly exothermic polymerization reaction takes place followed by a slightly exothermic reaction, and we want to minimize the duration of the operation of the process. Various operational as well as quality and safety related...

Electrical losses are converted into thermal energy in motors, which heats each component. It is a significant factor decreasing motor mechanical performance. In this paper, the cooling characteristics were analyzed according to design factors of water jacket investigate performance permanent magnet synchronous (PMSM). First, electrical generated PMSM calculated using electromagnetic finite ele...
