Buch. Zustand: Neu. Neuware - As a byproduct of historical development, there are different, unrelated systems of nomenclature for 'inorganic chemistry,' 'organic chemistry,' 'polymer chemistry,' 'natural products chemistry,' etc. With each new discovery in the laboratory, as well as each new theoretical proposal for a chemical, the lines that traditionally have separated these 'distinct' subsets of matter continually grow more blurred. This lack of uniformity in characterizing and naming chemicals increases the communication difficulties between differently trained chemists, as well as other scientists, and greatly impedes progress. With the set of known chemicals numbering over 42,000,000 (in Chemical Abstracts' data base) and continually growing (about 2,000 new additions every day), the desirability for a unified system for naming all chemicals simultaneously grows. Moreover, in order to meet the requirements of disparate groups of scientists, and of society in general, the name assigned to a given chemical should, not only uniquely describe that substance, but also should be a part of a readily recognizable order for the entire field. For these purposes, a topology-based 'bi-parametric' system of nomenclature is herein proposed. - In this book, a new nomenclature system is proposed- The new nomenclature is applicable to a three dimensional world, and is internally consistent- This nomenclature unifies ALL branches of chemistry, removing the need for various presently existing sets of rules.

Buch. Zustand: Neu. Neuware - The book is devoted to various constructions of sets which are nonmeasurable with respect to invariant (more generally, quasi-invariant) measures. Our starting point is the classical Vitali theorem stating the existence of subsets of the real line which are not measurable in the Lebesgue sense. This theorem stimulated the development of the following interesting topics in mathematics: 1. Paradoxical decompositions of sets in finite-dimensional Euclidean spaces; 2. The theory of non-real-valued-measurable cardinals; 3. The theory of invariant (quasi-invariant)extensions of invariant (quasi-invariant) measures. These topics are under consideration in the book. The role of nonmeasurable sets (functions) in point set theory and real analysis is underlined and various classes of such sets (functions) are investigated . Among them there are: Vitali sets, Bernstein sets, Sierpinski sets, nontrivial solutions of the Cauchy functional equation, absolutely nonmeasurable sets in uncountable groups, absolutely nonmeasurable additive functions, thick uniform subsets of the plane, small nonmeasurable sets, absolutely negligible sets, etc. The importance of properties of nonmeasurable sets for various aspects of the measure extension problem is shown. It is also demonstrated that there are close relationships between the existence of nonmeasurable sets and some deep questions of axiomatic set theory, infinite combinatorics, set-theoretical topology, general theory of commutative groups. Many open attractive problems are formulated concerning nonmeasurable sets and functions. highlights the importance of nonmeasurable sets (functions) for general measure extension problem.Deep connections of the topic with set theory, real analysis, infinite combinatorics, group theory and geometry of Euclidean spaces shown and underlined. self-contained and accessible for a wide audience of potential readers. Each chapter ends with exercises which p.

Buch. Zustand: Neu. Neuware - This international symposium allowed many researchers and industrial representatives to meet and discuss a broad spectrum of information such as zero emission, resources availability, sustainable utilization of resources, bioactive and functional components in aquatic organisms, utilization of wastes, seafood quality, surimi technologies and processing and safety. The book aims: To provide a current record presented in the international symposium More Efficient Utilization of Fish and Fisheries Products, 7-10 October 2001, Kyoto, Japan; To provide a stimulus to researchers in this area to cross-fertilize ideas and demonstrate examples of success; To enhance values and returns to fisheries fields in national and international terms by providing descriptions of better techniques and methods for utilizing the catch, reducing waste, and providing valuable by-products.

Buch. Zustand: Neu. Neuware - Part of the 'Handbook of Analytical Separations' series, this volume gives an overview about methods to analyse drugs in biological fluids. It covers the general aspects important for conducting therapeutic drug monitoring or pharmacokinetics studies. It discusses areas where therapeutic drug monitoring is used frequently.

Buch. Zustand: Neu. Neuware - Since the first date of publication of this book in 1991, the subject of phosphors and luminescence has assumed even more importance in the overall scheme of technological development. Many new types of displays have appeared which depend upon phosphors in their operation. Some of these were pure conjecture in 1991 but are a reality in 2004. Descriptions have been included of the newer (as well as the older) types of displays in this edition along with an annotated portrait of the phosphors used in each category. Many of these new light sources promise to displace and make obsolete our current light sources, such as incandescent lamps, fluorescent lamps and the ubiquitous colour Cathode Ray Tube now used in TV and computer monitors. The importance of solid state science are summarized in the introductory chapters of this edition, and many of the chapters have been completely rewritten or revised. Each chapter has a special contribution to make in the overall understanding of the solid state science of phosphors and luminescence.

Buch. Zustand: Neu. Neuware - Traditionally, process design and control system design are performed sequentially. It is only recently displayed that a simultaneous approach to the design and control leads to significant economic benefits and improved dynamic performance during plant operation.
