  • Quality Assurance for Environmental Analysis

    Method Evaluation within the Measurements and Testing Programme (BCR)
    • 1st Edition
    • Volume 17

    Quality assurance (QA) for environmental analysis is a growing feature of the nineties as is illustrated by the number of QA guidelines and systems which are being implemented nowadays. There is, however, often a huge gap between the implementation and respect of QA guidelines and the technical approach undertaken to improve and validate new analytical methods. This is particularly true for complex determinations involving multi-step methodologies such as those used in speciation and organic analyses.Quality assurance may also be considered from the technical point of view, which is the focus of this book. The techniques used in different analytical fields (inorganic, speciation and organic analysis) are critically reviewed (i.e. discussion of advantages and limitations) and existing tools for evaluating their performance are described (e.g. interlaboratory studies, use of certified reference materials). Particular reference is made to the activities of the Measurements and Testing Programme (BCR) of the European Commission towards the improvement of quality control of environmental analysis.The book has been written by experienced practitioners. By its nature, it serves as a practical reference for postgraduate students and environmental chemists who need a wide overview of the techniques used in environmental analysis and existing ways of evaluating the performance of relevant analytical methods. The critical discussions of the methods described, as well as the development of quality assurance aspects, makes it unique.

  • Lignites of North America

    • 1st Edition
    • Volume 23
    • H.H. Schobert
    • English
    Providing a comprehensive survey of the origin, the fundamental properties, and the technology of utilization of the lignites of North America, this book will be of particular interest to professional scientists and engineers working in coal research or coal technology. Coals display a continuum of properties, often with no sharp, steep change between ranks and thus the book restricts the discussion strictly to lignites (with the occasional comparisons with other coals).There is a very extensive index, making the contents of the book easily accessible to the reader.

  • Quantitative Treatments of Solute/Solvent Interactions

    • 1st Edition
    • Volume 1
    • P. Politzer + 1 more
    • English
    The primary objective of this volume, the first in a new series entitled Theoretical and Computational Chemistry, is to survey some effective approaches to understanding, describing and predicting ways in which solutes and solvents interact and the effects they have upon each other. The treatment of solute/solvent interactions that is presented emphasizes a synergism between theory and experiment. Data obtained experimentally are used as a basis for developing quantitative theoretical models that permit the correlation and interpretation of the data, and also provide a predictive capability. The latter being of course a key motivation for these efforts. Linear solvation energy relationships have been quite successful in this respect and accordingly receive considerable attention. Other effective approaches, including computational ones, are also being pursued, and are discussed in several chapters. This is an area that is continually evolving, and it is hoped that the present volume will convey a sense of its dynamic nature.

  • Advances in Developmental Biology

    • Volume 3a
    • Paul Wassarman
    • English
    Volume 3 of Advances in Developmental Biology and Biochemistry consists of five chapters that review specific aspects of mammalian, fly, and ascidian development. In Chapter 1, J. Campos-Ortega discusses mechanisms of neurogenesis in Drosophila, with special attention given to the process of separation of epidermal and neural progenitor cells. In Chapter 2, D. Rappolee and Z. Werb discuss the role of growth factors in early mammalian embryos and compare genes used in mouse with those used in Xenopus and chick. In Chapter 3, E. Linney and A.-S. LaMantia discuss the range of malformations resulting from retinoid teratogenesis, the molecular biology of retinoids, the use of transgenic mice to study retinoid signaling, and differentiation of the CNS in the context of retinoid signaling. In Chapter 4, E. Gavis and R. Lehmann discuss pathways and components involved in RNA localization and targeting in Drosophila oocytes. In Chapter 5, W. Jeffery discusses the use of actin as a tissue-specific marker in studies of ascidian development and evolution

  • Chromatography in the Petroleum Industry

    • 1st Edition
    • Volume 56
    • E.R. Adlard
    • English
    Petroleum mixtures consist primarily of relatively unreactive complex hydrocarbons covering a wide boiling range. Such mixtures are difficult to separate by most analytical techniques. Therefore, the petroleum industry has for many years played a leading role in the development of chromatographic methods of analysis. Since the last book specifically concerned with chromatographic analysis of petroleum appeared 15 years ago, numerous advances have been made including developments in liquid and supercritical fluid chromatography, the advent of silica capillary columns with bonded stationary phases and the commercial availability of new selective detectors.The current book contains chapters written by experts concerning the analysis of mixtures ranging from low boiling gases to waxes and crude oils. Silica capillary columns offer excellent resolution but they cannot separate all mixtures; therefore a chapter is devoted to the powerful complementary technique of multidimensional gas chromatography. The analysis of polymers by hydrodynamic chromatography is described as is the analysis of aqueous ionic mixtures by capillary electrophoresis. The atomic emission detector, the oxygen FID and the sulfur chemiluminescence detectors are described and a chapter is devoted to data handling.Although the volume is specifically aimed at the petroleum analyst, there is much information of general interest which should be of benefit to a very wide readership.

  • Wavelets in Image Communication

    • 1st Edition
    • Volume 5
    • M. Barlaud
    • English
    The rapid advancements in image communication technologies are documented in the book series, Advances in Image Communication. Each publication provides an in-depth exploration of an intrinsic element of the multi-disciplinary field and together they form a comprehensive overview of the whole.This volume, the fifth in the series, examines the definition, study and use of the wavelet transform in communications for two-dimensional (2-D) digital signals. The transform is used for signal reorganization before compression and the trade-off between these two steps and the whole compression process is discussed.The five chapters specifically present the theory of wavelets applied to images, then applications of compression of still images and sequences. Chapter 1 introduces biorthogonal bases of compactly supported wavelets: this generalization of orthonormal wavelet theory allows the use of linear phase filters. A non rectangular wavelet representation of 2-D signals is developed in the second chapter: the properties usually used with wavelets, phase, linearity, and regularity are discussed. Chapter 3 is composed of three parts: a description of commonly used biorthogonal wavelets; a presentation of vector quantization algorithms; a consideration of lattice vector quantization followed by a discussion of the bit allocation procedure (with experimental results given). The fourth chapter deals with a region-based discrete wavelet transform for image coding. Chapter 5 investigates the transmission of image sequences: wavelet transforms and motion estimation are detailed in a multiconstraint approach of image sequence coding.
