While preventive maintenance is concerned with regularly testing, and reconditioning equipment to prevent failures in service and premature deterioration, it follows that predictive maintenance procedures are concerned with the ability to predict when the equipment will fail and then developing schedules to implement timely repairs. Predictive maintenance does not imply that with the use of these techniques, failure modes in equipment can be prevented rather, it suggests that the occurrence of failure can be predicted and thus planned for. An appropriate example would be the inspection and change of a major compressor face-type oil seal where random heat checking (FM) has been observed over the years. 

If, in the same way, we use (72) to define for the other processes the characteristic units J, L, and Y, similar remarks can be made with regard to J and J, with regard to L and L, and likewise with regard to Y and Y. By equation (72) a precise definition has been given to the characteristic unit of any process and we must hope that in the future the study of ionic solutions will eventually provide a complete interpretation of these quantities. At the present time we are very far from this goal. At any rate the total unitary quantity for each process must be isolated and evaluated before it can be interpreted. In the remaining chapters of this book we shall have occasion to mention only the quantities D, L, Y, J, and U, defined in accordance with (72) and (73). If, however, anyone should wish to give a precise definition to a quantity that includes less than the whole of the unitary term, the symbols in bold-faced type remain available for this purpose. 

Names of compounds m small capital Utters indicate substances for which directions are given the numbers m bold face type refer to volumes of Organic Syntheses, numbers in italics refer to pages in those volumes on which preparative directions are given and num bers in Arabic refer to pages on which the compounds or subjects are mentioned in connection with other preparations For example Acetoacetic Ester 4 45 6, 36 indicates... 

Each entry in both Part I and Part II is followed by the volume number or numbers in bold-face type and the page number on which the compound or subject is to be found. Entries in capital letters indicate compounds, reactions, or methods appearing in the title of the preparation. 

The ScbOnflies symbols are usually not written in bold-face type, although they are represented by nuances such as given in Eqs. (104) and (105). 

All equations are given on a dimensionally consistent basis and can be used with any dimensionally consistent units. The illustrative units given in the following are based on the MKSA system, using the rational basis for electrical units. For the cgs-esu (irrational) system, the corresponding cgs-esu units would be used and the permittivity, e, would have a value ofl/(47r). Universal constants and defined values are represented by a symbol in Gothic (sans serif) or in bold face type.

Data from Pugmire and Grant, 1968, corrected for changes in A . Portions alpha to nitrogen are in bold-face type. 

Page numbers in bold-faced type refer to experimental procedures. Numbers followed by an asterisk refer particularly to qualitative organic analysis. Numbers followed by a dagger t refer to apparatus with ground glass joints. Numbers followed by a double dagger refer to reaction mechanisms. 

Names in small capital letters refer to the titles of individual preparations. A number in ordinary bold-face type denotes the volume. A number in bold-face italics refers to a page which gives preparative directions for substances formed either as principal products or as by-products numbers in ordinary type indicate pages on which a compound or a subject is mentioned in connection with other preparations. For example. Acetone cyanohydrin, SO, 42, 43, indicates that acetone cyanohydrin is mentioned on page 42, and that directions for its preparation are given in detail on page 43, of Volume 20. 

The hydrate structures (Figure 1.5) are composed of five polyhedra formed by hydrogen-bonded water molecules shown in Figure 2.5, with properties tabulated in Table 2.1. Jeffrey (1984) suggested the nomenclature description (ft" 1), for these polyhedra, where i is the number of edges in face type i, and tm is the number of faces with m edges. 

Review articles are indicated by the words Review(s) or Book/Books in bold-faced type.
