Substituted heat-reactive resins are most widely used in contact-adhesive appHcations and, to a lesser extent, in coatings (77,78) -butylphenol, cresol, and nonylphenol are most frequendy used. The alkyl group increases compatibiHty with oleoresinous varnishes and alkyds. In combination with these resins, phenoHcs reduce water sensitivity. Common appHcations include baked-on and electrical insulation varnishes, and as modifiers for baking alkyds, rosin, and ester gum systems. Substituted heat-reactive resins are not used for air-dry coatings because of theh soft, tacky nature in the uncured state substituted nonheat-reactive phenoHcs are the modifying resin of choice in this case. 

In contrast, Ernst et al, (1996) have shown that a substitution at Ser264 does not necessarily lead to herbicide resistance. They found both Ser and Gly at position 264 in various sensitive and resistant biotypes of common groundsel. However, all resistant biotypes of black nightshade had Gly at position 264, but some of the sensitive biotypes also had Gly at this position. They suggested that the effect of this mutation in sensitive biotypes was overcome by two additional mutations in these biotypes alanine at position 251 (Ala25i) to arginine (Arg) and valine at position 280 (Val280) to leucine (Leu). In sensitive common lambsquarters, only Ser was present at position 264 either Ser or Gly were detected at position 264 in different atrazine-resistant plants (Ernst et al, 1996).

Analytical absorption spectroscopy in the ultraviolet and visible regions of the elechomagnetic spectrum has been widely used in pharmaceutical and biomedical analysis for quantitative purposes and, with certain limitations, for the characterisation of drugs, impurities, metabolites, and related substances. By contrast, luminescence methods, and fluorescence spectroscopy in particular, have been less widely exploited, despite the undoubted advantages of greater specificity and sensitivity commonly observed for fluorescent species. However, the wider availability of spectrofluorimeters capable of presenting corrected excitation and emission spectra, coupled with the fact that reliable fluorogenic reactions now permit non-fluorescent species to be examined fluorimetrically, has led to a renaissance of interest in fluorimetric methods in biomedical analysis.

Of all the commonly met factors - shape, size, concentration, intimacy of mixing - it is the temperature to which affairs are nearly always most sensitive. Commonly a system will ignite if it is too hot, or if its surroundings exceed a critical temperature. But it is usually a crude simplification and frequently meaningless to ascribe a critical ignition temperature to any particular substance its mass, arrangement and its surroundings are all involved. This has been known and emphasized [7] for more than sixty years. 

The proton is the most popular nucleus for peptide studies, mainly because of its high detection sensitivity, common occurrence, and high natural abundance. The other nuclei occurring in peptides can provide information complementary to that obtained from protons technological advances have now rendered practical the study of these less sensitive nuclei in peptides. The properties of some nuclei useful for studies of peptides are presented in Table II.
