List of Examples

Whenever possible, relative comparisons of risk should be made (Step 8). Comparing relative risk estimates for alternative strategies avoids many of the problems associated with interpreting and defending absolute estimates. Table 9 contains examples of typical conclusions you can reach using relative risk estimates. In some cases, however, absolute estimates may be required to satisfy your needs. Table 10 contains a list of examples of typical conclusions possible using absolute risk estimates. 

In commercial plastics materials there are a comparatively limited number of chemical structures to be found and it is possible to make some general observations about chemical reactivity in the following tabulated list of examples ... 

In this listing of examples, I have excluded straight metallurgical journals and the many devoted to solid-state physics, such as the venerable Philosophieal Magazine and Physieal Review B. 

Caneer is a disorder of the body s eontrol of die growth of eells. The disease may be genetie or influeneed by life style or exposure to eertain ehemieals, termed eareinogens. For a list of examples of human ehemieal eareinogens, and the relevant target organs, refer to Table 5.10. 

These methods deal with specific cases. The list of examples is not exhaustive. The low-T (200-300°C) decomposition of the transition-metal borohydrides M(BH4> , e.g., leads to titanium, zirconium, halfnium, uranium and thorium borides . Alternatively, the uranium diboride may be obtained by reacting uranium hydride with diborane in hydrogen at 200-400°C. 

This topic has been mentioned in Section V, Failure, Defect and Contaminant Analysis, in Chapter 15, where a number of typical practical problem invetsigations were presented. Obviously the potential list of examples exhibiting different characteristics and requiring a different type of analysis is lengthy. When the sample is heterogeneous, e.g., a polymer blend or a composite, the study of the surface of a failed piece of material may reveal whether the problem is the interface of the components or that failure occurred within one of these. In particular in the case of crazing or necking orientation may have been induced, the way this can be analysed is discussed in Chapter 8. 

A list of examples in this section is not exhaustive rather, they have been chosen to illustrate the different approaches used for immobilization of the catalysts for important classes of organic reactions, namely hydrogenation, oxidation, and coupling reactions. Due to the major industrial importance of olefin polymerization (see Chapter 9.1), and although the objectives of immobilization of polymerization catalysts are rather different from the other examples, some references to this will also be given here. 

The preceding list of examples, which is by no means exhaustive, confirms that the determination of heats of adsorption is of both fundamental and practical importance. However, in contrast with this basic importance which cannot be overemphasised (9), data on heats of adsorption, and particularly on calorimetric heats of irreversible adsorption processes, are relatively incomplete, as the careful perusal of any textbook on adsorption or heterogeneous catalysis will show. 

The traditional technique of reducing nitro compounds with iron powder in dilute acid (Bechamps-Brimmeyr reduction) continues to be used for nitro compounds that are adversely affected by the catalytic reduction method with hydrogen. The list of examples includes aromatic nitro compounds carrying halogen substituents, especially if these are attached in ortho or para position to the nitro group. The solution containing only a small amount of acid (such as acetic acid) is almost neutral and allows iron to precipitate as Fe304. 

Prosite is perhaps the best known of the domain databases (Hofmann et al., 1999). The Prosite database is a good source of high quality annotation for protein domain families. Prosite documentation includes a section on the functional meaning of a match to the entry and a list of example members of the family. Prosite documentation also includes literature references and cross links to other databases such as the PDB collection of protein structures (Bernstein et al., 1977). For each Prosite document, there is a Prosite pattern, profile, or both to detect the domain family. The profiles are the most sensitive detection method in Prosite. The Prosite profiles provide Zscores for matches allowing statistical evaluation of the match to a new protein. Profiles are now available for many of the common protein domains. Prosite profiles use the generalized profile software (Bucher et al., 1996). 

A short list of examples of structure descriptions in terms of combination of invariant lattice complexes is here reported. (Compare with the structure descriptions in Chapter 7.)... 

By now a broad range of SAMs on various substrates are available. For an overview on SAM systems several comprehensive reviews [1-4] as well as the reference book by A. Ulman are available [5]. In Tab. 9.1 a list of examples is given [5, 6, 33]. 

This definition may be difficult to use in practice without examples. Different companies may interpret it in different ways. To develop a common understanding of the term, a company may choose to develop a list of examples it believes to be near misses. Some stated common examples of near miss incidents might include ... 

All male fish pheromones are steroidal (Sorensen and Stacey, 1990). Many male fish release chemicals that attract females, stimulate them to spawn, and inhibit their aggression. As early as 1982, Liley compiled a long list of examples testes, as in goldfish (Stacey and Hourston, 1982), urogenital fluid, glands on the caudal peduncle (an anal fin appendage), mucus and urine, can be sources of male pheromones. 

Many organometallic catalysts are soluble in ionic liquids, especially including ionic compounds. Neutral species, such as Wilkinson s catalyst, are also soluble to some extent in ionic liquids (169). There are numerous examples illustrating the dispersion and isolation of organometallic catalysts in ionic liquids a list of examples is given in a recent review (/). 

True alkaloids derive from amino acid and they share a heterocyclic ring with nitrogen. These alkaloids are highly reactive substances with biological activity even in low doses. All true alkaloids have a bitter taste and appear as a white solid, with the exception of nicotine which has a brown liquid. True alkaloids form water-soluble salts. Moreover, most of them are well-defined crystalline substances which unite with acids to form salts. True alkaloids may occur in plants (1) in the free state, (2) as salts and (3) as N-oxides. These alkaloids occur in a limited number of species and families, and are those compounds in which decarboxylated amino acids are condensed with a non-nitrogenous structural moiety. The primary precursors of true alkaloids are such amino acids as L-ornithine, L-lysine, L-phenylalanine/L-tyrosine, L-tryptophan and L-histidine . Examples of true alkaloids include such biologically active alkaloids as cocaine, quinine, dopamine, morphine and usambarensine (Figure 4). A fuller list of examples appears in Table 1.
