Theories and Principles

A system is an ordered set of ideas, principles, and theories or a chain of operations that produces specific results to be a chain of operations, the operations need to work together in a regular relationship. A quality system is not a random collection of procedures (which many quality systems are) and therefore quality systems, like air conditioning systems, need to be designed. All the components need to fit together, the inputs and outputs need to be connected, sensors need to feed information to processes which cause changes in performance and all parts need to work together to achieve a common purpose i.e. to ensure that products conform to specified requirements. You may in fact already have a kind of quality system in place. You may have rules and methods which your staff follow in order to ensure product conforms to customer requirements, but they may not be documented. Even if some are documented, unless they reflect a chain of operations that produces consistent results, they cannot be considered to be a system.

The principle and theory of the ACE method is discussed in detail in Part I of this book and were recently reviewed elsewhere (68-70). The remainder of this section is focused on the recent applications of ACE for studying GAG-protein and polysaccharide-protein interactions. 

An apparatus with high sensitivity is the heat-flow microcalorimeter originally developed by Calvet and Prat [139] based on the design of Tian [140]. Several Tian-Calvet type microcalorimeters have been designed [141-144]. In the Calvet microcalorimeter, heat flow is measured between the system and the heat block itself. The principles and theory of heat-flow microcalorimetry, the analysis of calorimetric data, as well as the merits and limitations of the various applications of adsorption calorimetry to the study of heterogeneous catalysis have been discussed in several reviews [61,118,134,135,141,145]. The Tian-Calvet type calorimeters are preferred because they have been shown to be reliable, can be used with a wide variety of solids, can follow both slow and fast processes, and can be operated over a reasonably broad temperature range [118,135]. The apparatus is composed by an experimental vessel, where the system is located, which is contained into a calorimetric block (Figure 13.3 [146]). 

Geochemical Kinetics is a textbook for graduate students and advanced undergraduate students. This book is based on my courses on geochemical kinetics at the University of Michigan, Ann Arbor. Its aim is to provide a comprehensive introduction to the principles and theories of geochemical kinetics. It is hoped that students and scientists in geochemical kinetics will use this book as a standard reference. 

Ecotoxicology is a natural extension of toxicology that studies the fate and effects of toxic substances on an ecosystem. It is based on scientiflc research that employs both laboratory and held methods. Ecotoxicology requires an understanding of ecologic principles and theories pertaining to how chemicals can affect individuals, populations, communities, and ecosystems. Individuals are single entities, whereas a... 

Following an introductory section on the historical background that has led to the development of RPC techniques as practiced today, the principles and theory of RPC will be discussed, incorporating the role of amino acid sequence and hierarchical structural effects that determine the outcome of the interaction of a peptide(s) with various types of nonpolar chromatographic surfaces. Subsequently, the influence of operating parameters such as the effects of different (1) surface morphologies or chemistries of nonpolar sorbents (2) concentrations of organic solvents, salts, or other mobile-phase additives (3) pH conditions or...

Principles and theories can help you up to a point. They can provide you with ideas, suggest what things you might look out for, help you analyse situations, indicate possible ways forweird. But no theoiy or principle learned in a book or classroom can tell you precisely what to do in your precise circumstances. That you have to discover for yourself - anew in each fresh situation.

Table 6.3 provides a summary of the different microscopic techniques that have been applied to hydrate studies and the type of information that can be obtained from these tools. The following discussion provides a brief overview of the application of diffraction and spectroscopy to study hydrate structure and dynamics, and formation/decomposition kinetics. For information on the principles and theory of these techniques, the reader is referred to the following texts on x-ray diffraction (Hammond, 2001), neutron scattering (Higgins and Benoit, 1996), NMR spectroscopy (Abragam, 1961 Schmidt-Rohr and Spiess, 1994), and Raman spectroscopy (Lewis and Edwards, 2001).
