Advances in Developmental Biology
1st Edition
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
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.
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.

Carbohydrate Analysis
High Performance Liquid Chromatography and Capillary Electrophoresis
1st Edition
Volume 58
Z. El Rassi
English
Carbohydrates and glycoconjugates play an important role in several life processes. The wide variety of carbohydrate species and their inherent polydispersity and heterogeneity require separation techniques of high resolving power and high selectivity such as high performance liquid chromatography (HPLC) and capillary electrophoresis (HPCE). In the last decade HPLC, and recently HPCE methods have been developed for the high resolution and reproducible quantitation of carbohydrates. Despite the importance of these two column separation technologies in the area of carbohydrates, no previous book describes specialized methods for the separation, purification and detection of carbohydrates and glycoconjugates by HPLC and HPCE.Therefore, the objective of the present book is to provide a comprehensive review of carbohydrate analysis by HPLC and HPCE by covering analytical and preparative separation techniques for all classes of carbohydrates including mono- and disaccharides; linear and cyclic oligosaccharides; branched heterooligosaccharid... (e.g., glycans, plant-derived oligosaccharides); glycoconjugates (e.g., glycolipids, glycoproteins); carbohydrates in food and beverage; compositional carbohydrates of polysaccharides; carbohydrates in biomass degradation; etc.The book will be of interest to a wide audience, including analytical chemists and biochemists, carbohydrate, glycoprotein and glycolipid chemists, molecular biologists, biotechnologists, etc. It will also be a useful reference work for both the experienced analyst and the newcomer as well as for users of HPLC and HPCE, graduates and postdoctoral students.
Archean Crustal Evolution
1st Edition
Volume 11
K.C. Condie
English
The integration of Tectonics/Geochemist... up-to-date reviews by leading scientists as well as a broad topical coverage of the Archean, are some of the features of this particular volume. As geochronology has progressed in the last 20 years, the Archean has continued to attract interest. Advancements in the understanding of Archean crustal and mantle evolution have progressed rapidly since the first International Archean Symposium in Western Australia (1970). The landmark for the Archean was the NATO Advanced Study Institute at Leicester (1975). At this meeting the Archean truly "came of age". Investigators from many different disciplines focused their expertise on the early history of the earth. For the first time, the nature of the atmosphere, oceans, and life during the Archean was an important part of an Archean symposium. During the most recent Archean Symposium in Perth in 1990, there was a shift in interest from field and trace element data to the new rapidly evolving high-precision U/Pb geochronology of Archean rocks and to detailed structural studies of both low and high grade Archean terrains. The terrane concept so widely applied to the Phanerozoic was proposed for the Archean Yilgarn Province in Western Australia and is now widely accepted for the Archean (as evident by the articles in this book). Plate tectonics is now widely accepted as the principal process that controls the history of continents and oceans. There are, though, well substantiated differences between Archean and post-Archean rocks that indicate that Archean tectonic regimes must have differed in some respects from modern ones. The question of how and to what degree did Archean plate tectonics differ from modern plate tectonics is treated in many of the chapters of this book. Altogether, the editor has presented a selection of articles that provide a fascinating insight into the latest observations in this field.
Catalyst Design for Tailor-Made Polyolefins
1st Edition
Volume 89
