Older identification

Three common risks from the only child s strong sense of individuality are personal entitlement (the belief that his or her individuality confers special status and deserves special treatment), older identification (subscribing to values and norms more associated with his or her parent s generation than with peers), and eccentricity (becoming so used to living on individual terms, that he or she significantly departs from social norms). 

Problems with older identification can cause the only child to embrace a set of cultural norms more associated with the parental generation than with his or her own. 

The yellow disulfide radical anion and the briUiant blue trisulfide radical anion often occur together for what reason some authors of the older Hterature (prior to 1975) got mixed up with their identification. Today, both species are well known by their E8R, infrared, resonance Raman, UV-Vis, and photoelectron spectra, some of which have been recorded both in solutions and in solid matrices. In solution these radical species are formed by the ho-molytic dissociation of polysulfide dianions according to Eqs. (7) and (8). 8ince these dissociation reactions are of course endothermic the radical formation is promoted by heating as well as by dilution. Furthermore, solvents of lower polarity than that of water also favor the homolytic dissociation. However, in solutions at 20 °C the equilibria at Eqs. (7) and (8) are usually on the left side (excepting extremely dilute systems) and only the very high sensitivity of E8R, UV-Vis and resonance Raman spectroscopy made it possible to detect the radical anions in liquid and solid solutions see above. 

In an acetone extract from a neoprene/SBR hose compound, Lattimer et al. [92] distinguished dioctylph-thalate (m/z 390), di(r-octyl)diphenylamine (m/z 393), 1,3,5-tris(3,5-di-f-butyl-4-hydroxybenzyl)-isocyanurate m/z 783), hydrocarbon oil and a paraffin wax (numerous molecular ions in the m/z range of 200-500) by means of FD-MS. Since cross-linked rubbers are insoluble, more complex extraction procedures must be carried out (Chapter 2). The method of Dinsmore and Smith [257], or a modification thereof, is normally used. Mass spectrometry (and other analytical techniques) is then used to characterise the various rubber fractions. The mass-spectral identification of numerous antioxidants (hindered phenols and aromatic amines, e.g. phenyl-/ -naphthyl-amine, 6-dodecyl-2,2,4-trimethyl-l,2-dihydroquinoline, butylated bisphenol-A, HPPD, poly-TMDQ, di-(t-octyl)diphenylamine) in rubber extracts by means of direct probe EI-MS with programmed heating, has been reported [252]. The main problem reported consisted of the numerous ions arising from hydrocarbon oil in the recipe. In older work, mass spectrometry has been used to qualitatively identify volatile AOs in sheet samples of SBR and rubber-type vulcanisates after extraction of the polymer with acetone [51,246]. 

The powdery sample (e.g. a mortar) is mixed with 60 100 pi of trypsin solution (see above). Usually 5 10 mg of model fresh mortar, containing about 100 pg of proteins, is sufficient for a reliable identification. In the case of older samples (model samples aged for 9 months were tested) about 100 mg of the material was necessary. Similar amounts of samples from buildings of different age (Section 6.4.4) were needed. 

All these results have confirmed that the described methodology can be used for the identification of proteinaceous binders in solid samples taken from historical objects. The method facilitates the distinction of the basic types of proteinaceous additives (milk proteins from collagenous, etc.) that are contained in low concentrations in medieval or even older samples. 

The word safety used to mean the older strategy of accident prevention through the use of hard hats, safety shoes, and a variety of rules and regulations. The main emphasis was on worker safety. Much more recently, safety has been replaced by loss prevention. This term includes hazard identification, technical evaluation, and the design of new engineering features to prevent loss. The subj ect of this text is loss prevention, but for convenience, the words safety and loss prevention will be used synonymously throughout.

There are however some older Asian examples of identification with king, dynasty or territory which have features of state nationalism. Pre-modern Chinese described their collective identity by reference to a dynasty— People of Han, or Tang, or Qing . Nevertheless, the state s requirement that officials be recruited through examinations of certain classical texts created an unusual uniformity of high culture (see below). 

Cyclopropanones deserve special comment, not because of their practical importance (they have no commercial value at this time), but because of their novel behavior and reactivity. No unambiguous synthesis of cyclopropanones was known prior to 1965, and the older textbooks usually contained statements such as cyclopropanones apparently cannot exist. However, they had been postulated as intermediates in various reactions (see, for example, the Favorskii rearrangement, Section 17-2C and Exercise 17-15), but until recently had defied isolation and identification. The problem is that the three-ring ketone is remarkably reactive, especially towards nucleophiles. Because of the associated relief of angle strain, nucleophiles readily add to the carbonyl group without the aid of a catalyst and give good yields of adducts from which the cyclopropanone is not easily recovered ... 

Raman, and nmr spectra. An extensive bibliography of older hard-copy ir spectra is given in The Coblent Sodety Desk Book of Infrared Spectra (62). Since the mid-1980s, comprehensive databases have been available in computerized form where the spectra themselves, not merely the bibliographic references, are searchable and displayable. The search algorithms vary considerably among the available systems no algorithm standard exists (ca 1994), but several are under development (63,64). Expert systems, which assist in the automatic interpretation and identification of spectra, have existed for many years but are not commonly used (65). Computerized spectral databases are either local, PC-based, or public.
