  • The Origin and Domestication of Cultivated Plants

    • 1st Edition
    • C. Barigozzi
    • English
    This book consists of the proceedings of a symposium organized by the Accademia Nazionale dei Lincei, Rome. The proceedings are unusual in that it is a rare event to see archaeologists and geneticists coming together to discuss the connection between historical facts and biological phenomena. The aim of the symposium was to discuss the origin of some important cultivated plants (wheat, maize, barley, oat, legumes and fruit trees) not only in relation to genetical mechanisms but also as a complex of historical facts recognizable through archaeological research.This international Meeting based on interdisciplinary concepts, met with a prompt and positive reaction from all those specialists invited to attend. The book itself is an unparalleled contribution to the interdisciplinary knowledge on the origin of crop plants and agriculture.
  • Advances in Composite Tribology

    • 1st Edition
    • Volume 8
    • K. Friedrich
    • English
    Much research has been carried out and a lot of progress has been made towards the use of composite materials in a wide field of tribological applications. In recent years studies have been made to determine to what degree phenomena governing the tribological performance of composites can be generalized and to consolidate interdisciplinary information for polymer-, metal- and ceramic matrix composites.The importance of promoting better knowledge in the areas of friction, lubrication and wear, in general, is demonstrated by the contents of this volume. It covers a wide range of subjects extending from fundamental research on the tribological characteristics of various multi-phase materials up to final applications of composites in wear loaded, technical components. Besides the emphasis on composites tribology, the great practical aspect of the field in many industrial applications is also reviewed by authors who are engaged in applied research as well as those in more academic activities. The articles in this volume will facilitate both researchers and mechanical designers in their work towards a set of predictive, materials engineering-related models for a more reliable use of composites as tribo-materials.Thro... the study of, and observation of, the tribology of sensibly formulated composite systems may emerge a clear and more profound understanding of the subject of tribology. In this sense, this book offers a major and critical evaluation of the state of understanding of the principles of tribology and its ability to serve the practical and commercial needs of this technology generally, and particularly in the context of composite systems.
  • Stress Responses of Photosynthetic Organisms

    Molecular Mechanisms and Molecular Regulations
    • 1st Edition
    • Kimiyuki Satoh + 1 more
    • English
    Sixteen topics from the results of the research project "Molecular Mechanisms for Responses of the Photosynthetic Apparatus to the Environment," are documented in this excellent and timely work.Photosynthesis research has a long history in Japan, and many Japanese laboratories working in this field have been very active and productive. Based on the foundation established by these laboratories, the research reflected in this book focuses on elucidating the interactions between photosynthesis and the environment, with special emphasis on the molecular aspects of these interactions. The major purpose of the research was to identify specific genes required for (a) repair of the organisms from stress-induced damage to the photosynthetic machinery and (b) acclimation of photosynthetic processes to specific changes in environmental conditions. Once specific genes were identified, the effects of expression (and overexpression) of these genes in transgenic plants on acclimation processes were analyzed.Through the analysis of transgenic plants and cyanobacteria, the volume clarifies a number of molecular mechanisms by which plants acclimate to environmental variations, and the factors that govern recovery from stress-induced damage, especially with respect to the photosynthetic apparatus.A treatize on stress physiology and photosynthesis, the book also indicates the agricultural usefulness of transgenic plants and microalgae which are produced to study the molecular mechanisms of the tolerance of plants to changes in their environment.
  • Regional Studies and Specific Deposits

    • 1st Edition
    • Volume 13
    • Bozzano G Luisa
    • English
    Regional Studies and Specific Deposits deals with regional studies of strata-bound and stratiform ore deposits. Topics covered include the geological association between coal and metallic ores; the genesis of iron ores in banded iron-formation (BIF) by supergene and supergene-metamorphi... processes; mineral zoning in sediment-hosted copper deposits; and the formation of gossans. The role of hydrothermal karst phenomena in the formation of Mississippi Valley-type deposits is also discussed. Comprised of five chapters, this volume begins with a review of the geological association of coal and metallic ores, focusing in particular on which metallic accumulations could be expected to be possibly present, within or close to the coal. The next chapter examines the origin of strata-bound enrichment deposits derived from BIF and presents the basic conceptual model for BIF-derived iron ores. The evolution of sulfide mineral zonation in low-temperature, sediment-hosted copper deposits is then evaluated. The book also describes the processes underlying the formation of gossans before concluding with an analysis of the hydrothermal karst phenomena as a factor in the development of Mississippi Valley-type deposits. This handbook will be useful to students, practitioners, and researchers in the fields of energy and earth sciences, mineralogy, mining, and metallurgy.

Chapters 3,4 and 5 of the fifth edition have been combined into one chapter, which is divided into sections devoted to the elements. These sections are arranged in alphabetical order to make for easier location of information on a given element. To further improve the usefulness of the volume, a reference list has been provided for each sub-section followed by a biography of the appropriate quantitative methods.
  • Heat Pumps for Energy Efficiency and Environmental Progress

    • 1st Edition
    • J. Bosma
    • English
    The 70 papers collected in this volume present an up to date review of the trends in heat pump technology. The heat pump is reviewed both as being part of a more comprehensive system, and as a refined device providing energy and greenhouse gas emission reductions. Its implementation in a system or process must be carefully considered at an early stage of design or development, and process integration is discussed in detail as a valuable tool for industry.The heat pump is proving to be a highly effective energy conserving tool, particularly when designed and used as an integral part of a system. Environmental benefits are gained when energy is conserved, and heat pumps can make a major contribution in this area. However, some heat pumps use working fluids which are environmentally unfriendly, and the progress that has been made in the field of alternative refrigerants is reported on. The volume will prove an indispensable reference source on the wide-ranging applications that have been developed since the last international conference, on such topics as heat pump field trials, pilot plants and development programmes.

Topics include rockslide kinematics, associated seismic activity, meteorological and hydrological conditions, mode of emplacement of other Alaskan rock avalanches, and applicability of mechanical fluidization to other rock avalanches. The text examines the mechanics of glacier movement, dynamics of snow avalanches, failure of snow slopes, and role of gravity in plate tectonics. The selection is a valuables reference for researchers wanting to study further rockslides and avalanches.
  • Physico-Chemical Properties of Selected Anionic, Cationic and Nonionic Surfactants

    • 1st Edition

    • English
    The number of physico-chemical investigations of surfactants in solution, whether aqueous or nonaqueous, has dramatically increased in recent years. However, literature reports on surfactants in solutions are scattered over a plethora of scientific journals and books which differ widely in scope and readership. Such data are often difficult to retrieve because there have been no systematic compilations, with the exception of those for CMCs and for micelle aggregation numbers. The present compilation meets that need by covering, as completely as possible, the physico-chemical properties of selected series of homologous surfactants. These surfactants are in most cases isomerically pure, are well-known, and have been used in numerous academic and industrial studies. The properties include aggregation number, cloud point, CMC, 13C-NMR, correlation length, counterion binding, density, enthalpy of micelle formation, entropy of micelle formation, Gibbs' free energy of micelle formation, head group area, 1H-NMR, hydration number, Krafft temperature, melting point, micelle radius, microscopic viscosity, miscibility curve, partial molar volume, phase inversion temperature, refractive index, self-diffusion coefficient, surface tension, and upper critical temperature. The book also contains two- and three-component phase diagrams of many nonionic surfactants.The solvent is water in most cases; however, some data refer to properties in D2O, electrolyte solutions, and nonaqueous solvents. The variables are temperature and concentration. Where possible, the method of measurement is given. Data on the purity of the compounds and the accuracy of the measurement methods are not included, as these can easily be found in the original sources, which mostly date from the period 1970-1991 and are given at the end of each chapter. The Index section contains a compound index, a property index, a symbol index and a cross index which facilitate easy access to the data.This valuable collection of data will be of great use to anyone involved in Colloid and Surface Science, academics as well as industrial workers, and will stimulate further work.
