Pursuit

In this way the student s knowledge of the organic reactions is consolidated as he proceeds through the sections, his experience of the general method of identification steadily increases, and the investigation of the unknown compounds forms a welcome break from the systematic pursuit of the sectional work. 

In discussing science we also need to define its scope, as well as the methods and views (concepts) involved in its pursuit. It is also useful to think about what science is not, although this can sometimes become controversial. Significant and important studies such as those concerned with the fields of sociology, politics, or economics increasingly use methods that previously were associated only with the physical and biological sciences or mathematics. However, I believe these... 

It is not particularly difficult to introduce thermodynamic concepts into a discussion of elasticity. We shall not explore all of the implications of this development, but shall proceed only to the point of establishing the connection between elasticity and entropy. Then we shall go from phenomenological thermodynamics to statistical thermodynamics in pursuit of a molecular model to describe the elastic response of cross-linked networks. 

Gold [7440-57-5] Au, is presumably the first metal known and used by humans. It occurs ia nature as a highly pure metal and is treasured because of its color, its extraordinary ductility, and its resistance to corrosion. Early uses ia medicine and dentistry date to the ancient Chinese and Egyptians. In the Middle Ages the demand for gold led to the iatense, unsuccesshil efforts of alchemists to convert base metals iato gold. These pursuits became the basis for chemical science. The search for gold has been an important factor ia world exploration and the development of world trade. 

The pursuit of further miniaturization of electronic circuits has made submicrometer resolution Hthography a cmcial element in future computer engineering. LB films have long been considered potential candidates for resist appHcations, because conventional spin-coated photoresist materials have large pinhole densities and variations of thickness. In contrast, LB films are two-dimensional, layered, crystalline soHds that provide high control of film thickness and are impermeable to plasma down to a thickness of 40 nm (46). The electron beam polymerization of CO-tricosenoic acid monolayers has been mentioned. Another monomeric amphiphile used in an attempt to develop electron-beam-resist materials is a-octadecylacryUc acid (8). 

The widespread use of cinnamic derivatives has led to the pursuit of reUable methods for thek dkect synthesis. Commercial processes have focused on condensation reactions between ben2aldehyde and a number of active methylene compounds for assembly of the requisite carbon skeleton. The presence of a disubstituted carbon—carbon double bond in the sidechain of these chemicals also gives rise to the existence of two distinct stereoisomers, the cis or (Z)- and trans or (E)- isomers ... 

In this era of globalization, anyone who wishes to remain in the race and to excel must make TQM an ultimate objective and remember that the pursuit of excellence is a never-ending journey . 

Against this backdrop, the quest for more efficient processes, more reliable equipment, downtime avoidance, and maintenance cost reductions is understandable. How are these pursuits structured Better yet, how should they be structured The answer is the real best-of-class, high profitability performers who are hard at work changing old ways of thinking. They are willing to reassess work processes and work procedures. Best-of-class companies also revisit the basics while, understandably, engaging in the search for new and advanced technologies. 

The pursuit of product quality over the last few decades has been intense in many companies around the world, but in many sectors of industry, reliability is considered to be the most important quality attribute of the product (Kehoe, 1996). As consumers become more aware than ever of quality, their expectations for reliability are also increasing. Even equipment without obvious safety concerns can have important reliability implications. Most products can, therefore, benefit from the use of sound reliability techniques (Burns, 1994). Reliability prediction, in turn, has the benefit that it gives a quantifiable estimate of the likely reliability that can be assessed to see if this is appropriate for the market (Stephenson and Wallace, 1996). 

There are eurrently three main approaehes used in the pursuit of a reliable produet (Stephenson and Wallaee, 1996) ... 

Total overall performance effectiveness indicates PTPM s pursuit of maximum plant efficiency and minimum downtime. 

When the user and the vendor have worked together as a team, and if all people included give sufficient attention to details, the on-stream operation should be very smooth. While there are many details and, at times, endless questions to resolve, the conscientious pursuit of each item, no matter how trivial it may appear at the time, should result in an achievement of the objective. The unit should start and come on-stream with a minimum of effort. 

I have described Lifshin as a specialist in characterisation . This is almost a contradiction in terms, because the techniques that are sheltered under the characterisation umbrella are so numerous, varied and sophisticated that nobody can be truly expert in them all, even if his entire working time is devoted to the pursuit of characterisation. The problem is more serious for other materials scientists whose primary interest lies elsewhere. As Lifshin has expressed it in the preface to an encyclopedia of materials characterisation (Cahn and Lifshin 1993), scientists and engineers have enough difficulty in keeping up with advances in their own fields without having to be materials characterisation experts. However, it is essential to have enough basic understanding of currently used analytical methods to be able to interact effectively with such experts (my italics). ... 

One of the earliest observations of high eonductivity in sueh a material was in a form of poly(acetylene) by a Japanese team (Shirakawa and Ikeda 1971). Perhaps one should date the pursuit of semieondueting polymer deviees from that experiment. It soon became clear that conjugated polymers had a severe drawback most of them are extremely stable against potential solvents they cannot be forced... 

My son Andrew has steadfastly encouraged me in the writing of this book, and I thank him for this filial support. My dear wife, Pat, has commented on various passages. Moreover, she has made this whole enterprise feasible, not only by her confidence in her eccentric husband s successive pursuits but by always providing an affectionate domestic environment 1 cannot possibly ever thank her enough. 

The continued pursuit of semi-empirical methods for the prediction of adhesion is a worthy, if somewhat risky, enterprise. It may well lead to improved and more streamlined methods of finding new materials and methods, but lacking that, even its failures, if honestly evaluated, should lead to improved understanding of the complex phenomena of adhesion. 

Synthesis remains a dynamic and central area of chemistry. There are many new principles, strategies and methods of synthesis waiting to be discovered. If this volume is helpful to our many colleagues in the chemical world in their pursuit of discovery and new knowledge, a major objective of this book will have been met. 

We have only to look at the introductory clauses of ISO 9001 to find that the aim of the requirements is to achieve customer satisfaction by prevention of nonconformities. Hence quality management is a means for planning, organizing, and controlling the prevention of failure. All the tools and techniques that are used in quality management serve to improve our ability to succeed in our pursuit of excellence. 

The reaction of 9(1 l)-dehydro steroids with nitrosyl fluoride was studied by Grantz and Rosenthal in pursuit of an alternate source for the important 9a-fluoro-11-oxygenated steroids. As expected, reaction at the more hindered 9(1 l)-double bond proceeds more slowly than at either the 4- or 5-double bonds. After 10 days at 3°, 3 -acetoxy-5a-pregn-9(l l)-en-20-one (50) affords a 45% yield of the 9a-fluoro-ll-nitrimine (51). Other 9a-fluoro-ll-nitrimines were prepared and it was found that the presence of additional keto groups, particularly the 3-keto group gives rise to side products with a concomitant reduction in yield of the desired 9a-fluoro-ll-nitrimines. In the case of the A" -3-ketones the yield is reduced to 10 %. The steric hindrance...
