Definitions and Principles

When derivations or proofs of equations are called for, start from fundamental definitions and principles. 

Certain aspects of chemical science should be grasped before entering the domains of toxicology, risk assessment, and risk management. We need not dip into fundamental concepts and the lesson will be brief and of very limited scope. Many of the definitions and principles to be discussed are (or should be) well known by those who have passed through a high school chemistry course, even with relatively poor success, but we need to be reminded of them and keep them in mind, as matters of chemicals in the environment come under discussion later in the book. 

In this section we introduce some general principles concerning the coordination of ligands to ions in aqueous solution. These definitions and principles will be used again when we discuss complex formation in detail later in the book. The... 

Each area of science has its own specific vocabulary, and before proceeding further, it is worth considering how these definitions and principles are implemented when spectroscopic measurements are undertaken. 

In as much as Eqn. 4 is only based on definitions and principles of mechanics, it must be correct for a given peel angle. It will predict the variation of P with peel angle if... 

These applications clearly illustrate the tremendous potential of PI in chemical process industry. An attempt is made in this chapter to present an engineering perspective of PI with special attention towards catalytic processes. The next section presents the commonly reported definitions and principles of PI, followed by some of the classifications for PI from various standpoints, while the subsequent three sections present details on multifunctional operations, novel devices and alternate PI configurations. The last section discusses modeling and other issues.
