  • Polynyas: Windows to the World

    • 1st Edition
    • Volume 74
    • Walker O. Smith Jr. + 1 more
    • English
    Polynyas are relatively ice-free regions when compared to the areas around them, and have been suggested as being foci for energy transfer between the atmosphere and ocean, ice “factories”, and critical areas with respect to polar ecosystems and biogeochemical cycles. This volume presents an integrated, multidisciplinary review of polynyas in both the Arctic and Antarctic. It emphasizes the meteorology, ice dynamics, oceanography, biological components, chemistry, and modeling of these systems, particularly with respect to their roles in polar processes and distributions. The various interactions within polynyas, particularly between the physical forcing and biological responses, is emphasized, as are the potential changes in polynyas that might occur under a climate regime that is rapidly changing. The authors of the reviews are leaders among their respective countries in polynya research, and all are internationally recognized.

This approach lets the engineer take into account the essential mechanical properties of the material itself and special features of practical implementation, including manufacturing technology, experimental results, and design characteristics. Giving complete coverage of the topic: from basics and fundamentals to the advanced analysis including practical design and engineering applications. At the same time including a detailed and comprehensive coverage of the contemporary theoretical models at the micro- and macro- levels of material structure, practical methods and approaches, experimental results, and optimisation of composite material properties and component performance. The authors present the results of more than 30 year practical experience in the field of design and analysis of composite materials and structures.

  • A New Ecology

    Systems Perspective
    • 1st Edition
    • Sven Erik Jørgensen + 8 more
    • English
    A New Ecology presents an ecosystem theory based on the following ecosystem properties: physical openness, ontic openness, directionality, connectivity, a complex dynamic for growth and development, and a complex dynamic response to disturbances. Each of these properties is developed in detail to show that these basic and characteristic properties can be applied to explain a wide spectrum of ecological obsevations and convections. It is also shown that the properties have application for environmental management and for assessment of ecosystem health.

  • Fundamentals of Thermophotovoltaic Energy Conversion

    • 1st Edition
    • Donald Chubb
    • English
    This is a text book presenting the fundamentals of thermophotovoltaic(T... energy conversion suitable for an upper undergraduate or first year graduate course. In addition it can serve as a reference or design aid for engineers developing TPV systems. Each chapter includes a summary and concludes with a set of problems.The first chapter presents the electromagnetic theory and radiation transfer theory necessary to calculate the optical properties of the components in a TPV optical cavity. Using a simplified model, Chapter 2 develops expressions for the maximum efficiency and power density for an ideal TPV system. The next three chapters consider the three major components in a TPV system; the emitter, filter and photovoltaic(PV) array. Chapter 3 applies the electromagnetic theory and radiation transfer theory presented in Chapter 1 in the calculation of spectral emittance. From the spectral emittance the emitter efficiency is calculated. Chapter 4 discusses interference, plasma and resonant array filters plus an interference filter with an imbedded metallic layer, a combined interference-plasma filter and spectral control using a back surface reflector(BSR) on the PV array. The theory necessary to calculate the optical properties of these filters is presented. Chapter 5 presents the fundamentals of semiconductor PV cells. Using transport equations calculation of the current-voltage relation for a PV cell is carried out. Quantum efficiency, spectral response and the electrical equivalent circuit for a PV cell are introduced so that the PV cell efficiency and power output can be calculated.The final three chapters of the book consider the combination of the emitter, filter and PV array that make up the optical cavity of a TPV system. Chapter 6 applies radiation transfer theory to calculate the cavity efficiency of planar and cylindrical optical cavities. Also introduced in Chapter 6 are the overall TPV efficiency, thermal efficiency and PV efficiency. Leakage of radiation out of the optical cavity results in a significant loss in TPV efficiency. Chapter 7 considers that topic. The final chapter presents a model for a planar TPV system.Six appendices present background information necessary to carry out theoretical developments in the text. Two of the appendices include Mathematica programs for the spectral optical properties of multi-layer interference filters and a planar TPV system. Software is included for downloading all the programs within the book.

  • Late Quaternary Climate Change and Human Adaptation in Arid China

    • 1st Edition
    • Volume 9
    • D.B. Madsen + 2 more
    • English
    Due to political pressures, prior to the 1990s little was known about the nature of human foraging adaptations in the deserts, grasslands, and mountains of north western China during the last glacial period. Even less was known about the transition to agriculture that followed. Now open to foreign visitation, there is now an increasing understanding of the foraging strategies which led both to the development of millet agriculture and to the utilization of the extreme environments of the Tibetan Plateau. This text explores the transition from the foraging societies of the Late Paleolithic to the emergence of settled farming societies and the emergent pastoralism of the middle Neolithic striving to help answer the diverse and numerous questions of this critical transitional period.

  • Passive Sampling Techniques in Environmental Monitoring

    • 1st Edition
    • Volume 48
    • Richard Greenwood + 2 more
    • English
    Monitoring pollutants in air, soil and water is a routine requirement in the workplace, and in the wider environment. Passive samplers can provide a representative picture of levels of pollutants over a period of time from days to months by measuring the average concentrations to which they have been exposed. Air monitors are widely used, for instance to measure the exposure of workers to volatile compounds, but also for monitoring the fate of pollutants in the atmosphere. Passive sampling devices are now becomining increasingly used to monitor pollutants in rivers, coastal waters and ground water where contamination results from sources such as domestic and industrial discharges, and the use of agrochemicals. Passive Sampling Techniques in Environmental Monitoring provides a timely collection of information on a set of techniques that help monitor the quality of air, surface and ground waters. Passive sampling can provide an inexpensive means of obtaining a representative picture of quality over a period of time, even where levels of pollutants fluctuate due to discontinuous discharges or seasonal application of chemicals such as pesticides. Recent changes in legislation have increased the pressure to obtain better information than that provided by classical infrequent spot sampling.Brought together in one source, this book looks at the performance of a range of devices for the passive sampling of metals, and of non-polar and polar organic chemicals in air and in water. The strengths and weaknesses and the range of applicability of the technology are considered.

  • Side Effects of Drugs Annual

    The Side Effects of Drugs Annual was first published in 1977. It has been continually published since then, as a yearly update to the voluminous encyclopedia Meyler's Side Effects of Drugs. Each new Annual continues to provide clinicians and medical investigators with a reliable and critical yearly survey of new data and trends in the area of Adverse Drug Reactions and Interactions. An international team of specialists has contributed to the Annuals by selecting critically from each year's writing all that is truly new and informative, by critically interpreting it, and by pointing to whatever is misleading.

  • Concise Encyclopedia of the Mechanical Properties of Materials

    • 1st Edition
    • J. W. Martin
    • English
    The Concise Encyclopedia of the Mechanical Properties of Materials draws its material from the award-winning Encyclopedia of Materials: Science and Technology, and includes updates and revisions not available in the original set. Mechanical properties describe the response of a material to an applied strain. Elastic behaviour is encountered at small strains, followed by plastic strain which is usually followed by fracture. If the magnitude of the applied strain fluctuates with time, fatigue failure may take place. Again, at relatively high temperatures (with respect to their melting point) materials subjected to a constant stress may exhibit progressive creep deformation over a period of time which may lead to ultimate failure. Articles have been selected which discuss this wide range of properties, both generally and also specifically with reference to metals and alloys, polymeric materials, ceramics and glasses, composite materials, as well as some miscellaneous materials such as wood, paper and textiles. The majority of contributions contain quantitative data, the others are predominantly descriptive in nature where it is more appropriate for the type of material in question. The compilation provides the reader with an up-to-date understanding of the mechanical properties of a wide range of materials.
