Supremacy

Nitration can be effected under a wide variety of conditions, as already indicated. The characteristics and kinetics exhibited by the reactions depend on the reagents used, but, as the mechanisms have been elucidated, the surprising fact has emerged that the nitronium ion is preeminently effective as the electrophilic species. The evidence for the operation of other electrophiles will be discussed, but it can be said that the supremacy of one electrophile is uncharacteristic of electrophilic substitutions, and bestows on nitration great utility as a model reaction. 

Many lens casters use the term hard-resin lenses for DADC products companies and trade names include American Optical (Aoflte ), Cobum (Supremacy I), Optical Radiation (Orcoflte), and Silor Optical (Orma 1000). Additional information can be obtained from the Optical Manufacturers Association, Falls Church, Va. Cast sheets of homopolymer and copolymers are suppHed by the SGL Homalite Company, Foster Grant, and others. 

Last Sunday, three drunken men with three sober women were at the bar celebrating the LIniversity of Connecticut s supremacy on the basketball courts—what a sports watcher called Coed Huskie Mania. Bodi die men s and women s teams went on to win National Collegiate Atiiletic Association championship tides on Monday and Tuesday nights.)... 

Can computers, therefore, have any hope of being competing with humans at synthesis, or will people maintain supremacy over machines for the foreseeable future Fortunately for computers, there is another approach to solving the problem of chemistry. In the introduction to his book. The Nature of the Chemical Bond (Pauling 1945), Pauling gives his opinion that it should be possible to describe structural chemistry in a satisfactory manner without the use of advanced mathematics. Books such as this have probably been more influential in the development of modern... 

Lindblom and Blander (1980) have given a number of examples of relevance in the pharmaceutical industry. These include C-alkylations, 0-alkylations, and A-alkylations. The C-alkylation of phenylacetonitrile, (mono- and di-) alkylation of benzylpenicillin with a-chlorodiethyl carbonate (where the acid part and the halide part in the esterification would have degraded quickly under normal conditions adopted for the reaction), A-alkylation of purines and adenine, etc. are discussed at some length and the supremacy of PTC is clearly shown.

Therefore, HPLC has been evolved as a dire confluence of need, technological supremacy, the emergence of newer theoretical concepts and ideas towards development along rational lines, and above all- the human desire to minimise work . HPLC offers numerous advantages as stated below ... 

The question, then, is simply whether white stewardship is to be benign or not—the tenor of European supremacy, not the fact of it, is the ultimate stake in the poly- versus monogenesis debate, so far as Prichard is concerned. 

Hence the rhetoric and visual lexicon of pan-white supremacy had a particular appeal in the political culture of the West from the 1870s onward. According to an 1870 tract by John Swinton, for instance, the...

Figure 2.19 displays the supremacy of the polyethylene family with roughly 70% of the film market. 

Figure 2.22 shows the supremacy of polyethylene and thermoplastic polyester (PET) in the European bottle and other blow-moulded container market. 

Statistics differ according to the source and the country considered. For example, window frames can be mainly made of PVC in one country and of a composite in another. Figure 2.23(a) displays an example of plastic shares in the building market, showing the supremacy of thermoplastics, but different data can be found. 

Table 2.28 displays some recent thermoplastic market shares for Western Europe. Note the supremacy of PVC followed by PS with thermoset competition for insulation.
