Fundamental Concepts and Terminology

Comparison of these models quickly shows that they are all very similar. There are differences in terminology and emphasis, but the fundamental concepts of process safety management are consistent. For example ... 

The second contribution we present in two parts. In this first part we discuss definitions and terminology, mostly from recognized sources [2-9], Some ideas in this article go beyond established international understandings they are introduced for debate and possible refinement. The terms used here are responsive to the fundamental concepts under which chemical analysts can formally substantiate and record a traceability link. A chain of such links should lead from the value of a quantity in a sample up to a unit in the International... 

Many synthetic chemists are reluctant to use polymeric reagents and catalysts because they do not understand polymers, or because they have been educated to believe that polymer chemistry is not pure. The development of polymer chemistry does lag behind that of organic chemistry. But after all, the concept of the macromolecule was generally accepted only around 1930, whereas urea was synthesized first in 1828. Its relative youth helps make polymer chemistry an exciting field of research, wide open for further exploration. For the benefit of readers who lack a fundamental background in polymer chemistry, the overview chapter includes a short section of basic terminology and concepts that should help in understanding the up-to-date reviews of research that follow. 

In step 7 of the design process, we discussed optimization. Let us now use the next example to introduce you to some of the fundamental concepts of optimization and its terminology. 

This brief explanation of the terminology of polarography and of some fundamental concepts should suffice for the explications which are to follow. More detailed information on this method may be found in numerous fundamental papers and monographs (1-6), and in an earlier volume of this series (7). 

This chapter has presented a brief history of fuel cell evolution, the electrochemical fundamentals of PEM fuel cells, PEM fuel cell concepts and terminology, as well as performance analysis. Its main purpose has been to provide readers with some introductory and background information for a fundamental understanding of fuel cell AC impedance, to facilitate their journey through the next several chapters. 

Some basic concepts and definitions of terms used in the polymer literature are reviewed in this chapter. Much of the terminology in current use in polymer science has technological origins, and some meanings may therefore be understood by convention as well as by definition. Some of these terms are included in this chapter since a full appreciation of the behavior and potential of polymeric materials requires acquaintance with technical developments as well as with the more academic fundamentals of the field. An aim of this book is to provide the reader with the basic understanding and vocabulary for further independent study in both areas.
