  • Wave Fields in Real Media

    Wave Propagation in Anisotropic, Anelastic and Porous Media
    • 1st Edition
    • Volume 31
    • José M. Carcione
    • English
    This book examines the differences between an ideal and a real description of wave propagation, where ideal means an elastic (lossless), isotropic and single-phase medium, and real means an anelastic, anisotropic and multi-phase medium. The analysis starts by introducing the relevant stress-strain relation. This relation and the equations of momentum conservation are combined to give the equation of motion. The differential formulation is written in terms of memory variables, and Biot's theory is used to describe wave propagation in porous media. For each rheology, a plane-wave analysis is performed in order to understand the physics of wave propagation. The book contains a review of the main direct numerical methods for solving the equation of motion in the time and space domains. The emphasis is on geophysical applications for seismic exploration, but researchers in the fields of earthquake seismology, rock acoustics, and material science - including many branches of acoustics of fluids and solids - may also find this text useful.

  • The Outer Heliosphere: The Next Frontiers

    The eleventh COSPAR colloquium The Outer Heliosphere: The Next Frontiers was held in Potsdam, Germany, from 24-28 July, 2000, and is the second dedicated to this subject after the first one held in Warsaw, Poland in 1989.Roughly a century has passed after the first ideas by Oliver Lodge, George Francis Fitzgerald and Kristan Birkeland about particle clouds emanating from the Sun and interacting with the Earth environment. Only a few decades after the formulation of the concepts of a continuous solar corpuscular radiation by Ludwig Bierman and a solar wind by Eugene Parker, heliospheric physics has evolved into an important branch of astrophysical research. Numerous spacecraft missions have increased the knowledge about the heliosphere tremendously. Now, at the beginning of a new millenium it seems possible, by newly developed propulasion technologies to send a spacecraft beyond the boundaries of the heliosphere. Such an Interstellar Proce will start the in-situ exploration of interstellar space and, thus, can be considered as the first true astrophysical spacecraft. The year 2000 appeared to be a highly welcome occassion to review the achievements since the last COSPAR Colloquia 11 years ago, to summarize the present developments and to give new impulse for future activities in heliospheric research.

  • Clinical Geropsychology

    Comprehensive Clinical Psychology Volume 7
    • 1st Edition
    • B.A. Edelstein
    • English
    The principal goal of Clinical Geropsychology was to assemble the contributions of a group of international experts whose work has focused on the psychology of aging and the field of clinical geropsychology. The chapters in this volume survey many of the significant contributions to our knowledge of the mental health problems of older adults, their clinical assessment, and the empirical support for our clinical interventions.In 1900 the average life expectancy in the USA was 49 years. There was relatively little need at that time for a psychology of aging, much less a clinical psychology of aging. That situation has dramatically changed over the past century and will continue to do so for many years. Today, adults 65 years of age and older comprise approximately 12.7% of the US population. With increasing age come increased risks of physical health problems and the field of clinical geropsychology continues to evolve as more researchers and clinicians begin to address the mental health needs of our increasing older adult population.Clinical Geropsychology examines the emerging field of clinical psychology beginning with a review of this area of research, presenting important epidemiological information. The volume then offers a detailed look at issues that range from analyzing physiological and cognitive aspects to cognitive changes and specific neurological disorders common among older adults. Specific topics covered include sexuality, bereavement, anxiety, substance abuse, and schizophrenia. Each chapter presents a summary of clinical research and its practical application. Voids in the knowledge base are also noted, along with recommendations for the direction of future investigations. The volume also addresses management problems such as incontinence, wandering, and aggressive behavior, and reviews the various mental health care systems available in different countries.Clinical Geropsychology was previously published as Volume 7 of the highly acclaimed major reference work, Comprehensive Clinical Psychology, the single, most comprehensive source of information in the field of Clinical Psychology.

  • Advances in Enzyme Regulation

    • George Weber
    • English
    Stepping ahead of the general front, Volume 41 in the series Advances in Enzyme Regulation moves the studies of mammalian enzymic and metabolic regulation forward.This volume was dedicated on the centenary of his birth to Sir Hans A. Krebs who gave the Special Symposium lectures for 15 years. George Weber spoke on the joint work he carried out in Oxford with Krebs and his associates, entitled "Cancer and Clinical Targeting."Much of the Symposium centered on novel aspects of signal transduction, including Inositol Signaling and on phosphatidylinositol 3'kinase and kinase B. The Special Symposium Lecture was given on Inositol Lipid Signaling in the Nucleus.The location and regulation of protein kinases were discussed.Clinical aspects of enzyme regulation were presented featuring studies on dihydrophyrimidine dehydrogenase, development, citrullinemia and human melanoma heparanase.Drug targeting and resistance were reviewed featuring etoposide and tumor vasculature. Regulation of pyruvate dehydrogenase kinase and abrogration of cytokine-dependency were analyzed. Challenging results on mRNA stability and apoptosis were presented covering cyclooxygenase-2 inhibitors, lysosomal cathepsins, human breast tumors and actin reorganization. The contents listed below provide a complete overview of topics and speakers.

  • Regulation of Phytochemicals by Molecular Techniques

    • 1st Edition
    • Volume 35
    • J.A. Saunders + 2 more
    • English
    The papers assembled in this volume were originally presented at the joint meeting of the Phytochemical Society of North America and the Mid-Atlantic Plant Molecular Biology Society, in August 2000. The symposium from which these chapters were prepared was entitled "Regulation of Phytochemicals by Molecular Techniques" and was organised by James Saunders and Ben Matthews. This joint meeting was timely because of recent landmark advances in molecular biology and genomics as well as the renewed interest in phytochemistry as a rich source of nutraceuticals, drugs, and alternatives to synthetic agriculture pesticides. Progress in genome sequencing in plants such as Arabidopsis and rice has been remarkable, as have expressed sequence tag (EST) projects in other plants, including maize and soybean. Recently, private and public sector participants of the Human Genome Project announced that a rough draft of the human genome has been constructed. These advances directly influence phytochemical investigations by providing both insight and tools for exploring and manipulating genomes.The chapters cover a wide range of applications from molecular biology to phytochemistry, and from basic studies on promoters and gene expression to pathway regulation and engineering with transformed plants. A number of noteworthy aspects emerge from this volume: applications of molecular biology to phytochemical practical problems are succeeding; newly emerging molecular tools promise to open new doors to discovery; and remarkable progress has already occurred in phytochemical pathway engineering.

    Children and Adolescents: Clinical Formulation & Treatment draws on the experience and research of leading scientists and clinicians from the United States, Australia, the United Kingdom, Israel and Canada to present state-of-the-art information on all aspects of child psychology and psychiatry. Special attention is given to the psychopathology, assessment, treatment, and prevention of childhood behavioral disorders. The volume highlights the developmental-contex... framework used in the clinical formulation of these disorders, as well as process and outcome issues in treatment. Various theoretical perspectives are also reviewed, including applied behavior analysis, family systems therapy, play therapy, and pharmacologic therapy. In the final section, all of the major childhood disorders found in the DSM and ICD are described, with information on their prevalence, etiology, assessment, and treatment. This section also analyzes the empirical status of the various therapies used for the treatment of childhood disorders. Section I examines the foundations for the conceptualization, assessment, and treatment of child psychopathology. Section II reviews major theoretical approaches that have been used in the treatment of diverse child behavior disorders. Chapters use a similar format to discuss the approach including the following: theoretical underpinnings; history and current status; assessment and clinical formulation; description of the intervention procedures; proposed mechanisms of change; research findings; future directions for research and practice. Section III addresses major child psychopathologies, their assessment, and treatment. Also using a structured format, chapters in this section include: a review of the disorder under consideration and exploration of its phenomenology, prevalence, etiology, and diagnostic features; a detailed examination of the conceptualization and clinical formulation of the disorder, its multimethod and multisource assessment; psychosocial and pharmacological treatment; future directions for research and practice. Children and Adolescents: Clinical Formulation & Treatment was previously published as Volume 5 of the highly acclaimed major reference work, Comprehensive Clinical Psychology, the single, most comprehensive source of information in the field of Clinical Psychology.

  • Computational Neural Networks for Geophysical Data Processing

    • 1st Edition
    • Volume 30
    • M.M. Poulton
    • English
    This book was primarily written for an audience that has heard about neural networks or has had some experience with the algorithms, but would like to gain a deeper understanding of the fundamental material. For those that already have a solid grasp of how to create a neural network application, this work can provide a wide range of examples of nuances in network design, data set design, testing strategy, and error analysis.Computation... rather than artificial, modifiers are used for neural networks in this book to make a distinction between networks that are implemented in hardware and those that are implemented in software. The term artificial neural network covers any implementation that is inorganic and is the most general term. Computational neural networks are only implemented in software but represent the vast majority of applications.While this book cannot provide a blue print for every conceivable geophysics application, it does outline a basic approach that has been used successfully.
