Topics of this Book

A being in the fourth dimension could see all our nerves at once or look inside our intestines and remove tumors without ever cutting our skin. The powers of these hyperbeings are a central topic of this book. 

As explained above, three fundamental models of crystal growth mechanism were established in relation to the roughness of interfaces these are illustrated in Fig. 3.14. At present, there is no other known growth mechanism that is essentially different from these three. Therefore, we shall analyze the morphology of crystals, the main topic of this book, based on these three growth mechanisms. 

As a preliminary to the main topics of this book - molecular structure and chemical bonding - this chapter is included to remind the reader of the foundations of atomic theory, an understanding of which is necessary for the assimilation of the main subject matter. 

Although engineering plastics in the topic of this book, I would maintain that the end user must have broad product interests spanning the offerings of the entire industry. I would also maintain that while some of us close to the trees may view an engineering plastic as one having some balance of properties which are different from products like polyethylene or polystyrene and PVC, the end user doesn t necessarily have the same pair of glasses. 

Hantzch synthesis is a well-known pathway to dihydro derivatives of azines. In some of the variations of this synthesis, the electrophilic reagents can be unsaturated ketones (Scheme 3.1, reactions a and b). Hantzch syntheses, including reaction b in Scheme 3.1 in which enamines are formed in situ from ammonia and the corresponding carbonyls, are not a topic of this book. However, synthetic applications of such condensations were described in detail in some reviews [1,2]. 

Because of their important application value, much research and development on the preparation technologies of ultrafine powders has been carried out in the last twenty years and more, and hundreds of preparation methods have been proposed. Since they are not the major topic of this book, neither a description of the classification of the methods nor an introduction to the details of the various methods will be covered here. On the other hand, reaction-precipitation methods generally have a number of advantages such as lower cost, moderate operating conditions, lower equipment requirements, convenience of operation, and normally yield good-performing products etc. thus they occupy an important position among the various methods. 

The confluence of theory and experiment achieved in recent years has greatly deepened our understanding of molecular photodissociation. At this point, however, it is important to underline that the cornerstone of realistic dynamical investigations is a multi-dimensional potential energy surface (PES). The interrelation between PESs on one hand and the various dissociation cross sections on the other hand is one prominent topic of this book and therefore we think it is useful to elucidate some qualitative aspects of PESs before we start with the development of the dynamical concepts. 

The purpose of this chapter of the book is to provide the analyst with a supplementary up-to-date reference source that describes analytical procedures for detecting and characterizing drug substances and related impurities in a variety of matrices from plant extracts to drug product. This chapter is meant to complement the preceding chapters and to direct the reader to references on topics not discussed in the preceding chapters but considered relevant to the topic of this book. 

The topic of this book is focused on active masses containing carbon, either as an active mass (e.g., negative mass of lithium-ion battery or electrical double layer capacitors), as an electronically conducting additive, or as an electronically conductive support for catalysts. In some cases, carbon can also be used as a current collector (e.g., Leclanche cell). This chapter presents the basic electrochemical characterization methods, as applicable to carbon-based active materials used in energy storage and laboratory scale devices. 

Gay-Lussac (1778-1850) wrote in 1809 We are perhaps not far removed from the time when we shall be able to submit the bulk of chemical phenomena to calculaton [31], One hundred and ten years later, in 1998, John Pople shared the Nobel Prize in Chemistry for his development of computational methods in chemistry, with Walter Kohn (in his case, for his development of the density-functional theory ), Figure 6-33. So even if Gay-Lussac was, perhaps, somewhat too optimistic, eventually his dreams came true—the development of computational chemistry has been amazing. Quantum chemistry is not a topic of this book, we are only mentioning it briefly because of its inherent relationship to the symmetry concept. For discussion of the topic we refer the reader to a few of the available monographs [32-36],... 

For molecules which are in the same state under the same condition, all of the methods illustrated in Fig. 2.2-1 may supply identical values for the vibrational frequencies of molecules in the electronic ground state. The methods, however, which are generally applied to most molecules are infrared and Raman spectroscopy - they are the topic of this book. 

Excellent reviews exist addressing the topic of chaos in atomic physics. The most comprehensive attempt at a review of the entire subject of quantum chaology and applications is a recent collection of reprints and original articles edited by Casati and Chirikov (1995). Its section on atoms in strong fields especially is highly relevant for the topic of this book. Additional material on chaos and irregularity in atomic physics can be found, e.g., in a collection of articles edited by Gay (1992). 

The central topic of this book is analytical Raman spectroscopy in terms of both techniques and applications. While there are many elegant treatments... 

The study by Freytet and Plaziat (1982) and the recent reviews by Freytet and Verrecchia (2002), Verrecchia (2002) and Alonso-Zarza (2003) provide excellent overviews of the petrography of lacustrine and palustrine deposits, and contain abundant photographs, information and references. In this section, only the main characteristic features associated with biogeochemi-cal lacustro-palustrine carbonate sediments will be described. Evaporitic sediments are the subject of another chapter (Chapter 10), and detrital sediments are not the topic of this book. As such, carbonates and organic sediments are the only facies that remain. 

Besides the measure of the dispersion of the one-dimensional projection i.e. the projective index, another distinction of PP PCA from the classical PCA is the procedure of computation. Since the projective index is the quadratic form of X as stated above, the extremal problem of Eqn. 1 can be turned into the problem of finding the eigenvalues and eigenvectors of the sample covariance matrix for which a lot of algorithms such as SVD, QR are available. Because of the adoption of the robust projective index in PP PCA, some nonlinear optimization approaches should be used. In order to guarantee the global optimum. Simulated annealing (SA) is adopted which is the main topic of this book. 

There are several different clustered search engines available. A case in point is Clusty.corn s Vivisimo [38], The default setting of this engine is to search the recent literature. Repeated searches, say at monthly intervals, enables one to keep up with topics of interest. A recent (June 2006) clustered search on Computational Toxicology, the topic of this book, gave the results described in Table 1.1.
