  • The rapid development of inorganic chemistry makes ever more challenging the task of providing a textbook that is contemporary and meets the needs of those who use it. We appreciate the constructive suggestions provided by students, faculty, and reviewers, and have adopted much of this advice, keeping in mind the constraints imposed by space and the scope of the book. The main emphasis in preparing this edition has been to bring it up to date while providing clarity and a variety of helpful features.

  • Unification-based grammar formalisms use structures containing sets of features to describe linguistic objects. Although computational algorithms for unification of feature structures have been worked out in experimental research, these algcwithms become quite complicated, and a more precise description of feature structures is desirable. We have developed a model in which descriptions of feature structures can be regarded as logical formulas, and interpreted by sets of directed graphs which satisfy them.

  • Wide agreement as to a clear and useful nomenclature is of great benefit in any field of science. The nomenclature here presented merits wide acceptance among terpene and other interested chemists because of the thorough way in which the careful work was done. Many versed in the chemistry of terpenes and many others experienced in naming chemical compounds were consulted. Full opportunity for criticism was offered.

  • Metal foams are a new, as yet imperfectly characterized, class of materials with low densities and novel physical, mechanical, thermal, electrical and acoustic properties. They offer potential for lightweight structures, for energy absorption, and for thermal management; and some of them, at least, are cheap. The current understanding of their production, properties and uses in assembled in this Design Guide.

  • One of the important consequences of the mere existence of this formula is the following. Suppose that g is the Lie algebra of a Lie group G. Then the local structure of G near the identity, i.e. the rule for the product of two elements of G sufficiently closed to the identity is determined by its Lie algebra g. Indeed, the exponential map is locally a diffeomorphism from a neighborhood of the origin in g onto a neighborhood W of the identity, and if U ⊂ W is a (possibly smaller) neighborhood of the identity such that U · U ⊂ W, the the product of a...

  • Carbohydrates are a versatile class of molecules of the formula (CH2O)n. They are a major form of stored energy in organisms, and they are the metabolic precursors of virtually all other biomolecules. Conjugates of carbohydrates with proteins and lipids perform a variety of functions, including recognition events that are important in cell growth, transformation, and other processes.

  • Human cytochrome P450 3A4 forms a series of minor testosterone hydroxylation products in addition to 6b-hy-droxytestosterone, the major product. One of these, formed at the next highest rate after the 6b-and 2b-hydroxy prod-ucts, was identified as 1b-hydroxytestosterone. This product was characterized from a mixture of testosterone oxidation products using an HPLC-solid phase extraction-cryoprobe NMR/time-of-flight mass spectrometry system, with an estimated total of6lgof this product.Mass spectrometry established the formula as C19H29O3(MH + 305.2080)....

  • In this volume I present some examples of Description of Surfaces, Partial Derivatives, Gradient, Directional Derivatives and Taylor’s Formula, cf. also Calculus 2b, Functions of Several Variables. Since my aim also has been to demonstrate some solution strategy I have as far as possible structured the examples according to the following form A Awareness, i.e. a short description of what is the problem. D Decision, i.e. a reflection over what should be done with the problem. I Implementation, i.e. where all the calculations are made. C Control, i.e. a test of the result....

  • The purpose of this chapter is largely to serve as an accessible introduction or a refresher of basic notions regarding analytic functions. We start by recalling the elementary theory of functions and their singularities in a style tuned to the needs of analytic combinatorics. Cauchy’s integral formula expresses coefficients of analytic functions as contour integrals. Suitable uses of Cauchy’s integral formula then make it possible to estimate such coefficients by suitably selecting an appropriate contour of integration.

  • The first edition of Toxicological Chemistry (1989) was written to bridge the gap between toxicology and chemistry. It defined toxicological chemistry as the science that deals with the chemical nature and reactions of toxic substances, their origins and uses, and the chemical aspects of their exposure, transformation, and elimination by biological systems. It emphasized the chemical formulas, structures, and reactions of toxic substances. The second edition of Toxicological Chemistry (1992) was significantly enlarged and increased in scope compared to the first edition.

  • The LabVIEW Tutorial contains the information you need to get started with the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software package. LabVIEW simplifies scientific computation, process control, and test and measurement applications, and you can also use it for a wide variety of other programming applications. This manual gives you an overview of the fundamental concepts of LabVIEW, and includes lessons to teach you what you need to know to build your own virtual instruments (VIs) as quickly as possible. This manual does not explain every LabVIEW feature.
