A Few Fundamental Concepts and Applications of Cryogenic Heat Transfer.
Peer reviewed Peer reviewed
Timmerhaus, Klaus D. – Chemical Engineering Education, 1981
Discusses low temperature heat transfer, transient heat transfer, and developments in steady state heat transfer. (SK)

A Note on Diffusive Mass Transport.
Peer reviewed Peer reviewed
Haynes, Henry W., Jr. – Chemical Engineering Education, 1986
Current chemical engineering textbooks teach that the driving force for diffusive mass transport in ideal solutions is the gradient in mole fraction. This is only true for ideal solution liquids. Therefore, it is shown that the appropriate driving force for use with ideal gases is the gradient in partial pressure. (JN)

The Curtin-Hammett Principle and the Winstein-Holness Equation.
Peer reviewed Peer reviewed
Seeman, Jeffrey I. – Journal of Chemical Education, 1986
Discusses: (1) the Curtin-Hammett (C-H) equation; (2) a direct relationship between product ratio and conformer distribution; (3) the Winstein-Holness (W-H) equation; (4) a combined kinetic treatment using a C-H/W-H utility; and (5) extensions of the C-H/W-H concepts. (JN)

A Theory of Frustration-Aggression.
Peer reviewed Peer reviewed
Gnepp, Eric H. – Psychology: A Quarterly Journal of Human Behavior, 1979
A three-dimensional theory of frustration-aggression is presented. It is proposed that aggressiveness can be measured by computing the kinetic energy of a response. Aggressiveness is equated with energy state. Experimental and laboratory procedures are outlined. (Author/BEF)

The Amateur Scientist.
Walker, Jearl – Scientific American, 1983
Discusses various physics concepts/principles that can be illustrated by amusement park rides. Examples of rotational dynamics, energy conservation, acceleration, and others can be demonstrated by such rides as roller coasters, Ferris wheels, and a variety of rotating rides. (JN)
Descriptors: Acceleration (Physics), College Science, Force, High Schools
