  • Non-Linear Mass Transfer and Hydrodynamic Stability

    • 1st Edition
    • C.B. Boyadjiev + 1 more
    • English
    Surveyed in this book are the kinetics of non-linear mass transfer and its effects on hydrodynamic stability in systems with intensive interphase mass transfer, in electrochemical systems with high current density and in chemically reacting systems.In Part 1 the non-linear mass transfer as a result of an intensive interphase mass transfer in the gas (liquid)-solid surface, gas-liquid and liquid-liquid systems is considered in the duffusion boundary layer approximation as well as in flat channel taking the longitudinal diffusion into account. The influence of the direction of the intensive interphase mass transfer on heat transfer and multi-component mass transfer is illustrated.Part 2 discusses non-linear mass transfer in electrochemical systems with high current density using the examples of the anode dissolving of metals in the electrolyte flow and the electro-separation of metals out of concentrated solutions. The theory of the measured electrochemical treatment of metals and alloys, which is a method of wide practical use, has been elaborated on this basis.In Part 3 the non-linear mass transfer in chemically reacting systems is considered in the cases of: non-linearity of the equations of the chemical reaction's kinetics and intensive interphase mass transfer or thermo-capillary effect due to chemical reactions. On this basis, the mechanisms and the macro-kinetics of the chemical transformations in the gas-liquid systems are discussed.Part 4 is dedicated to the chemical reaction kinetics in stationary two phase systems at an arbitrary contact time between phases.In Part 5 the effects of concentration gradients are considered in the approximations of the linear theory of the hydrodynamic stability of almost parallel flows.In systems with intensive interphase mass transfer, the Marangoni effect could also be observed, beside the effect of non-linear mass transfer. A comparative analysis of both effects is made in this book.

  • Power Geometry in Algebraic and Differential Equations

    • 1st Edition
    • Volume 57
    • A.D. Bruno
    • English
    The geometry of power exponents includes the Newton polyhedron, normal cones of its faces, power and logarithmic transformations. On the basis of the geometry universal algorithms for simplifications of systems of nonlinear equations (algebraic, ordinary differential and partial differential) were developed.The algorithms form a new calculus which allows to make local and asymptotical analysis of solutions to those systems.The efficiency of the calculus is demonstrated with regard to several complicated problems from Robotics, Celestial Mechanics, Hydrodynamics and Thermodynamics. The calculus also gives classical results obtained earlier intuitively and is an alternative to Algebraic Geometry, Differential Algebra, Lie group Analysis and Nonstandard Analysis.

  • Environmental Stressors and Gene Responses

    • 1st Edition
    • Volume 1
    • J.M. Storey + 1 more
    • English
    Cell and Molecular Responses to Stress is a new multi-volume book series from Elsevier Science that focuses on how organisms respond at a molecular level to environmental stresses imposed upon them. All organisms deal with variations in multiple environmental factors including temperature, oxygen, salinity, and water availability. Many show amazing tolerances to extreme stress with remarkable biochemical adaptations that allow life to persist under very difficult circumstances. This series explores the molecular mechanisms by which cells and organisms respond to stress, focusing on the variations in metabolic response that allow some cells and organisms to deal with extreme stress, others to endure stress within strict limits, and others to have a very low tolerance for changes in environmental parameters.Articles from within the series highlight the elastic limits of molecular responses in Nature, with examples drawn from animal, plant and bacteria systems.Volume 1, begins by considering some of the roles of environmental stress in determining the geographic distribution of animals and in promoting species divergence and then explores gene expression and metabolic responses to environmental stress with examples of adaptation to high and low temperature, osmotic, anoxia/ischemia, desiccation, high pressure and heavy metal stresses.

  • Wave Mechanics for Ocean Engineering

    • 1st Edition
    • Volume 64
    • Paolo Boccotti
    • English
    In a unitary way, this monograph deals with a wide range of subjects related to the mechanics of sea waves. The book highlights recent theoretical results on the dynamics of random wind-generated waves, on long-term wave statistics, and on beach planform evolution. A fresh approach is given to more traditional concepts. For example, new evidence from a recent series of small-scale field experiments is used to introduce some crucial topics like wave forces. Also, the book gives some worked examples for the design of offshore or coastal structures. An exciting subject dealt with in the book is the quasi-deterministic mechanics of three-dimensional wave groups in sea storms, and the loads exerted by these wave groups on offshore structures.The text is intended for researchers and graduate students in ocean engineering, but may also be understood by undergraduates. The more complex concepts are explained with examples or more extensive case studies.

  • Multi-Level Methods in Lubrication

    • 1st Edition
    • Volume 37
    • C.H. Venner + 1 more
    • English
    Efficient numerical solution of realistic and, therefore, complex equation systems occupies many researchers in many disciplines. For various reasons, but mainly in order to approximate reality, a very large number of unknowns are needed. Using classical techniques, the solution of such a system of equations would take too long, and so sometimes MultiLevel techniques are used to accelerate convergence. Over the last one and a half decades, the authors have studied the problem of Elastohydrodynamic Lubrication, governed by a complex integro-differential equation. Their work has resulted in a very efficient and stable solver. In this book they describe the different intermediate problems analyzed and solved, and how those ingredients finally come together in the EHL solver. A number of these intermediate problems, such as Hydrodynamic Lubrication and Dry Contact, are useful in their own right. In the Appendix the full codes of the Poisson problem, the Hydrodynamic Lubrication problem, the dry contact solver and the EHL solver are given. These codes are all written in 'C' language, based on the 'ANSI-C' version.

  • Cerebellar Modules: Molecules, Morphology, and Function

    • 1st Edition
    • Volume 124

    • English
    The present volume of Progress in Brain Research contains the proceedings of a Symposium entitled Cerebellar Modules: Molecules, Morphology and Function, which was held to mark the retirement of Jan Voogd as chairman of the Department of Anatomy at the Erasmus University of Rotterdam. The contributions of leading cerebellar scientists representing a variety of disciplines focussed around the issue of the cerebellar modular compartmentalization... the intriguing composition of which has for many decades been the driving force behind Voogd's extraordinarily detailed anatomical analyses.The first section of the book, Development, concentrates on the genetic basis of different aspects of compartmentalized development including a most important contribution on the postnatal development of the climbing fiber system. Gene expression is also an important element in the next section, Interneurons, which provides striking new data and hypotheses on the functional anatomy of granule cells, Golgi cells and unipolar brush cells. Particularly interesting are several contributions that offer a novel view on parallel fiber function. The section Modules and Circuits provides a number of state-of-the-art analyses using electrophysiological... and classical and transneuronal virus tracing techniques. The emphasis lies on the olivocerebellar circuits and the oculomotor system The final section, Models and Learning, offers an insight into the progress on the mechanisms and network organization of adaptation and learning, not only in classical paradigms like oculomotor and eye blink responses but also in studies linking gene expression to behavioral paradigmsThe editors are confident that the exciting data and concepts collected in this volume will strengthen the multidisciplinary approach in the field of cerebellar research.

  • Controlled Release Veterinary Drug Delivery

    Biological and Pharmaceutical Considerations
    • 1st Edition
    • Michael J. Rathbone + 1 more
    • English
    Many controlled release veterinary drug delivery systems (CRVDDS) are presently in use, and recently there has been a host of new CRVDDS within veterinary medicine. The challenges of this area of drug delivery arise from the unique anatomy and physiology of the target animal, the cost constraints associated with the value of the animal being treated and the extended periods of time that delivery must be sustained for (often measured in months).The purpose of this book is to introduce the reader to the unique opportunities and challenges of the field of CRVDDS and to explain and discuss the basic controlled release principles underlying the development of CRVDDS. Its aim is to provide an overview of many of the areas where CRVVDS have application, and to highlight the opportunities and prospects for controlled release technology in the veterinary field.Controlled Release Veterinary Drug Delivery comprises chapters that provide workers in the field (and those interested in this area) with information on the design, development and assessment of a variety of CRVDDS. The book contains chapters that describe the relevant animal physiological and anatomical considerations alongside descriptions of current and emerging controlled release delivery systems for a variety of routes for drug delivery, and present overviews on the physical and chemical assessment of veterinary controlled release delivery systems.The veterinary area is abound with opportunities for the development of controlled release drug delivery technologies. It is an area of medicine that is open to the acceptance of novel drug delivery devices, and which readily encompasses the use of novel routes of administration. It is an area of many unmet needs, most of which offer opportunities and unique challenges for the innovative formulation scientist to provide solutions. This book will provide an insight into the biological, clinical and pharmaceutical challenges that face the formulation scientist in this interesting and diverse area of research.

  • Fractals in Soil Science

    • 1st Edition
    • Volume 27
    • Y. Pachepsky + 2 more
    • English
    This book presents the state-of-the-art after fifteen years of exponentially growing applications of fractal geometry in soil science. It demonstrates the wide-ranging applicability of fractal models in soil science and indicates new opportunities to integrate processes in soils within or across scales using fractals. Contributed by some of the pioneers in the field, chapters represent a broad spectrum of applications from geochemistry to microbiology and from scales of micrometers to the landscape, and serve as an introduction to the subject.Topics include fractal aspects of soil structure, porosity and texture, scaling in preferential and hydraulic conductivity, anoxic volumes and adsorption in fractal models of soil, characterization of the pore surface irregularity, fractal properties of soil organic matter, fractal concepts in studies of soil fauna and mycelium in soils, and fractal analysis of spatial and temporal variability in soil properties and crop yields. A wide spectrum of methods for identifying and measuring fractal properties is introduced and critically discussed. Although the book focussed on solving problems in soil science, the applications and the fractal approach used share much in common with many other fields within and outside of the earth sciences. A unique bibliography on fractals in soils science is included.

  • Elsevier's Dictionary of Plant Names and their Origin

    In English (with definitions)
    • 1st Edition
    • D.C. Watts
    • English
    The dictionary contains about 30,000 vernacular and literary English names of plants (plus a few American), both wild and cultivated, with their botanical name and a brief account of the names' meaning if known. It was conceived as part of the author's wider interest in plant and tree lore, and ethnobotanical studies. Knowledge of plant names can give insight into largely forgotten beliefs. Why for example is, or was, the common red poppy known as "Blind Man"? An old superstition has it that if the poppy were put to the eyes it would cause blindness. Such names were probably the result of some taboo against picking the plant. Similarly, other names were likely to have been applied as a result of a country mother's warning to her children against eating poisonous berries. For the warning carries more weight when the name given to the berry reinforces the warning. Many such plants or fruits may be ascribed to the devil, Devil's Berries for Deadly Nightshade is an example.Names may also be purely descriptive, and can also serve to explain the meaning of the botanical name. Beauty-Berry is an example: it is the name given to the American shrub that belongs to the genus Callicarpa, which is made up of two Greek words that mean beauty and berry.Literary, or "book" names, have also been included in this dictionary, as being a very important part of the whole. Many of them provide links in the transmission of words through the ages. Thor's Beard, for example, is a book name for "houseleek", and has never been used in the dialect. But it highlights the legend that houseleek is a lightning plant, and by reverse logic is a preserver from fire.
