  • The Campanian-Maastrichtian Stage Boundary

    Characterisation and Correlation from Tercis-les-Bains (Landes, SW France) to Europe and Other Continents
    • 1st Edition
    • Volume 19
    • G.S. Odin
    • English
    The Phanerozoic calendar of the history of the earth is composed of fundamental units called stages. A priority of the International Commission on Stratigraphy is to redefine these stages using a modern approach. This work presents a unique solution to the previously debated and diversified locations of the Campanian-Maastricht... boundary, providing a precise correlation using the most accepted known time markers. The Campanian and the Maastrichtian are the last two stages of the Cretaceous System.This volume includes a large amount of previously unpublished stratigraphical data. With the use of uncertainty margins for observations, established by comparison of results obtained by various experts using different approaches for the same stratigraphical tool, a new approach to stratigraphical information was employed. While most of the data have been taken from the recently rediscovered geological site at Tercis, France, data from other sections around the world have been considered. The section studied at Tercis is the best stratigraphical record on Earth for the period of several million years across the Campanian-Maastricht... boundary.

  • Photomovement

    • 1st Edition
    • Volume 1
    • D.-P. Häder + 1 more
    • English
    This volume emphasizes the involvement of all facets of biology in the analysis of environmentally controlled movement responses. This includes biophysics, biochemistry, molecular biology and as an integral part of any approach to a closer understanding, physiology. The initial euphoria about molecular biology as the final solution for any problem has dwindled and the field agrees now that only the combined efforts of all facets of biology will at some day answer the question posed more than hundred years ago: "How can plants see?". One conclusion can be drawn from the current knowledge as summarized in this volume. The answer will most likely not be the same for all systems.

  • Insect Timing

    Circadian Rhythmicity to Seasonality
    • 1st Edition
    • D.L. Denlinger + 2 more
    • English
    Leading experts in the field bring together diverse aspects of insect timing mechanisms. This work combines three topics that are central to the understanding of biological timing in insects: circadian rhythms, photoperiodism, and diapause. The common theme underlining each of the contributions to this book is an understanding of the timing of events in the insect life cycle. Most daily activities (emergence, feeding, mating, egg laying, etc.) undertaken by insects occur at precise times each day. Likewise, seasonal events such as the entry into or termination from an overwintering dormancy (diapause) occur at distinct times of the year. This book documents such events and provides an up-to-date interpretation of the molecular and physiological events undergirding these activities.The study of circadian rhythms has undergone a flowering in recent years with the molecular dissection of the components of the circadian clock. Now that many of the clock genes have been identified it is possible to track daily patterns of clock-related mRNAs and proteins to link the entraining light cycles with molecular oscillations within the cell. Insect experiments have led the way in demonstrating that the concept of a "master clock" can no longer be used to explain the temporal organization within an animal. Insects have a multitude of cellular clocks that can function independently and retain their function under organ culture conditions, and they thus offer a premier system for studying how the hierarchical organization of clocks results in the overall temporal organization of the animal. Photoperiodism, and its most obvious manifestation, diapause, does not yet have the molecular underpinning that has been established for circadian rhythms, but recent studies are beginning to identify genes that appear to be involved in the regulation of diapause. Overall, the book presents the rich diversity of challenges and opportunities provided by insects for the study of timing mechanisms.

  • Biotechnology Annual Review

    • 1st Edition
    • Volume 7
    • M.R. El-Gewely
    • English
    Biotechnology is in many respects shaping our life and affecting our means of production and the creation of jobs. Progress in the applications of biotechnology depends on a wide base of basic as well as applied sciences. The output of biotechnology has already proved itself in many diverse fields from health to biomining and from agriculture to enzyme "breeding". It is therefore difficult to follow all of the current as well as the potential applications of biotechnology.The objective of the Biotechnology Annual Review series is to attempt to provide readers with the needed indepth knowledge, by reviewing specific topics in biotechnology in each issue. The philosophy behind this series is to encourage good reviews to make it easier for readers to keep in touch with progress and applications of biotechnology. Reviews on topics related to regulatory affairs, social impact of biotechnology, biodiversity, biosafety, public acceptance and patent issues are also encouraged.

  • Tribology Research: From Model Experiment to Industrial Problem

    A Century of Efforts in Mechanics, Materials Science and Physico-Chemistry
    • 1st Edition
    • Volume 39
    • G. Dalmaz + 3 more
    • English
    The 27th Leeds-Lyon Symposium on Tribology was held at the Institut National des Sciences Appliquées de Lyon, 5-8 September 2000. The central theme was: 'Tribology Research: From Model Experiment to Industrial Problem: A century of efforts in mechanics, materials science and physico-chemistry'. To celebrate the Year 2000, the organisers tried to achieve two different goals. First, to bring together contributions from the three major scientific fields that make up the Tribological community: mechanics, physico-chemistry and materials science. The second goal was to attract contributions ranging from complex industrial problems to model experiments.The conference began with two keynote lectures, the first being a detailed technical lecture on the dynamic behaviour of an elastic shaft supported by hydrodynamic bearings. The second was an overview of first principles multi-scale modelling of physicochemical aspects of tribology. Both of these interesting lectures are included in the proceedings volume.

  • Thin-Walled Structures - Advances and Developments

    • 1st Edition
    • J. Zaras + 2 more
    • English
    This volume contains the papers presented at the Third International Conference on Thin-Walled Structures, Cracow, Poland on June 5-7, 2001. There has been a substantial growth in knowledge in the field of Thin-Walled Structures over the past few decades. Lightweight structures are in widespread use in the Civil Engineering, Mechanical Engineering, Aeronautical, Automobile, Chemical and Offshore Engineering fields. The development of new processes, new methods of connections, new materials has gone hand-in-hand with the evolution of advanced analytical methods suitable for dealing with the increasing complexity of the design work involved in ensuring safety and confidence in the finished products.Of particular importance with regard to the analytical process is the growth in use of the finite element method. This method, about 40 years ago, was confined to rather specialist use, mainly in the aeronautical field, because of its requirements for substantial calculation capacity. The development over recent years of extremely powerful microcomputers has ensured that the application of the finite element method is now possible for problems in all fields of engineering, and a variety of finite element packages have been developed to enhance the ease of use and the availability of the method in the engineering design process.

  • Verified Synthesis of Zeolitic Materials

    Second Edition
    • 1st Edition
    • H. Robson
    • English
    Zeolite synthesis is an active field of research. As long as this continues, new phases will be discovered and new techniques for preparing existing phases will appear. This edition of Verified Synthesis of Zeolitic Materials contains all the recipes from the first edition plus 24 new recipes. Five new introductory articles have been included plus those from the first edition, some of which have been substantially revised. The XRD patterns have been recorded using different instrument settings from those in the first edition and are intended to conform to typical X-ray diffraction practice. In most cases, only the XRD pattern for the productas synthesised is printed here. The exceptions are those phases which show marked changes in the XRD pattern upon calcination.

  • Collection of Simulated XRD Powder Patterns for Zeolites

    • 1st Edition
    • M.M.J. Treacy + 1 more
    • English
    Collection of Simulated XRD Powder Patterns for Zeolites serves as a source of reference patterns for pure zeolite phases. The data will be helpful in establishing the structural purity of experimental phases and in indexing their diffraction patterns. The information will also aid in the determination of changes in the lattice parameters with changing composition, assessing preferred orientation effects, background evaluation, and line broadening. Also included are diffraction patterns of several common dense silicate phases to facilitate their detection in mixed phase synthesis.
