For the purpose of revealing the rather complicated thermodynamic surface of ordinary water substance in the critical region, a series of measurements of the PVT properties and the vapor-pressures of this technically important fluid have been performed by means of a constant-volume method....

An individual's behavior of is called purposive behavior, if it is based on the notion of having preference, pursuing goal, or maximizing his own interest. The goal or purpose of an individual often relates directly to others, and their behavior are often constrained by an environment that...
