    • Tuncer Cebeci
    • Inglés
    Analysis of Turbulent Boundary Layers focuses on turbulent flows meeting the requirements for the boundary-layer or thin-shear-layer approximations. Its approach is devising relatively fundamental, and often subtle, empirical engineering correlations, which are then introduced into various forms of describing equations for final solution. After introducing the topic on turbulence, the book examines the conservation equations for compressible turbulent flows, boundary-layer equations, and general behavior of turbulent boundary layers. The latter chapters describe the CS method for calculating two-dimensional and axisymmetric laminar and turbulent boundary layers. This book will be useful to readers who have advanced knowledge in fluid mechanics, especially to engineers who study the important problems of design.

    • Jerry Hatfield
    • Inglés
    Biometeorology in Integrated Pest Management is a resulting book from a conference with the same title held at the University of California in 1980. This book presents integrated pest management (IPM) in different viewpoints and perspectives. It serves as a helpful exchange of ideas to strengthen the research in integrated pest management. From a biometeorological viewpoint, the microclimate of agricultural systems is introduced in this book to describe the environment in which pests live. The first few chapters in this book discuss IPM in the perspective of biometeorology. Some of the topics include crop canopies (general heat exchange and wind movement), microclimate (instrumentation, techniques, and simulation), and microclimatic stress (remote sensing). The following section of the book focuses on plant pathology. The subject areas covered in this section include radiation quality and plant diseases; management of plant pathogens; and plant canopy modification and impact on plant disease. The last section focuses on weed science. The interaction of weeds to other pests, effects of light and temperature on weed growth, and weed seed germination are some of the topics discussed in this part. This book is a good source of reference to both students and professionals in the field of biometeorology, entomology, and agriculture. Other interested parties in the research of integrated pest management will also find this book helpful in their endeavors.

    • Inglés
    The Mycoplasmas,Volume V: Spiroplasmas, Acholeplasmas,and Mycoplasmas of Plants and Arthropods focuses on existing knowledge and recent development in research on spiroplasmas, acholeplasmas, and other mollicutes of plants and arthropods. Organized into 11 chapters, this volume discusses the nutrition, cultivation, ecology, and molecular and cellular biology of spiroplasmas. Because the occurrence of other mollicutes (mycoplasma and acholeplasma) in plant and arthropod environments is not extensively discussed in other volumes, this volume shows the rapid progress in describing the new mollicutes from arthropods and plant surface that they contaminate. Molecular studies of mollicute phylogeny and plant infections incited by the so-called mycoplasma-like organisms are also presented. This book will provide a comprehensive reference source for all mycoplasmologists and a relevant and exhaustive summary of recent advances in the study of spiroplasmas, acholeplasmas, and mycoplasmas in plant and arthropod hosts for microbiologists, cellular and molecular biologists, plant pathologists, and entomologists.

  • Biological Horizons in Surface Science

    • 1 Edición
    • L Prince
    • Inglés
    Biological Horizons in Surface Science presents techniques used in surface science research as well as experimental data. It is organized in such a way that there is a transition from the more theoretical or molecular to the more biological. Emphasis is placed on the importance of water in determining molecular architecture and interactions. Methods of examining molecular associations and complex formation of molecules are discussed, and the results from such studies are reviewed. Permeability is examined from the point of view of the energies required to penetrate between two different phases, and from the role that multicellular membranes may play in directing the diffusion of ions or solutes in general. Current concepts of membrane structure based on membrane models are discussed and some new models are suggested. Application of surface science techniques and the unique energies present at interphases are considered with regard to drug interaction with biological tissue and immunological phenomena. The importance of surfactant protein-lipid association is also discussed in regard to alveolar mechanics. This book is directed particularly to biologists who will find many of the techniques used of significance in their own research. It also aims to interest graduate students in this area of investigation.

  • Idiotypes

    • 1 Edición
    • Morris Reichin
    • Inglés
    Idiotypes documents the proceedings of an International Conference on Idiotypes held in Oklahoma City, Oklahoma, at the Oklahoma Medical Research Foundation, October 20-23, 1985. The aims of the conference were to gather active investigators in the study of idiotypes; to assess progress in the field; and to explore directions for future research. The papers presented at the conference cover a wide range of subjects. Several papers deal with defining protein and DNA sequences which determine idiotypes. Evidence points to germ line genes encoding the V region structures which underlie idiotypy. Another subtheme which concerns several contributions is the occurrence of dominant idiotypes in induced immune responses (e.g., arsonate and lysozyme) and autoimmunity (e.g., thyroglobulin and rheumatoid factors). The presence of such dominant idiotypes is discussed from several viewpoints, but the recurrent theme is that such dominance is a manifestation of a selection process inherent in the idiotypic network. Two papers deal with idiotypic structures in T cells: on the one hand, identifying idiotypes on T helper cells and, on the other, I-J and Iat related structures which tightly govern cellular interactions in the evolution of an immune response. Network interactions through autoanti-idiotypic responses are shown to be associated with the effects on the specificity of both induced and naturally occurring immune responses. Autoanti-idiotypic responses are also shown to be correlated with the regulation of the anti-DNA response in human systemic lupus erythematosus. These data pointed to a role of the idiotype network in immune regulation.

    • Inglés
    FROM THE PREFACE: Fortunately, chemistry--the root of all life processes--is becoming better understood and more accessible. A strong synergism between the chemical, agricultural, and related sciences is highly desirable. This handbook attempts to provide in easily accessible detail up-to-date information relevant to the stability of foods and beverages. Highly qualified scientists have compiled an extraordinary amount of data on the chemical, biochemical, and microbiological stability, along with sensory aspects, of selected foods and beverages. These data have been distilled and are presented mostly in tabular form, with a minimum of commentary whenever possible.****A total of 17 chapters (10 on food, 7 on beverages) by renowned experts in their particular fields from the United States, Europe, and Japan present a wealth of food and beverage stability information in handbook format. In particular, the chapters on fish and shellfish, cheese, and meat are remarkable in presenting data not readily available in an easily digestible form.****This handbook, encompassing as it does aging, shelf life, and stability--in short, the knowledge necessary to ensure preservation of our food supply--should help to bring about the above-mentioned synergism between chemical, agricultural, and related sciences. It is expected to fill a need, especially through the convenience of its tabular presentations.

    • Volumen 12
    • W.J. Mitsch + 2 más
    • Inglés
    The study of wetlands is a relatively new field and the modelling of these systems is still in its formative stages. Nevertheless, the editors felt compelled to assemble this volume as a first statement of the state of the art of modelling approaches for the quantitative study of wetlands. A global approach has been adopted in this book, not only by including a wide geographic distribution of wetlands, but also by including papers on both freshwater and saltwater wetlands. Wetlands are defined as systems intermediate between aquatic and terrestrial ecosystems, and include ecosystems under a wide range of hydrologic and ecologic conditions. The wetland types discussed in this book reflect that heterogeneity, ranging from intermittently flooded wet meadows to permanently flooded shallow reservoirs and lakes. Also included are modelling examples from coastal salt marshes, shallow estuaries, mesotrophic bogs, reedswamps, forested swamps, and regional wetlands. In summary, the book presents ecological modelling as a tool for management of these sensitive ecosystems, and for studying their structure and function. Each chapter has extensive references related to the modelling approach and wetland type discussed. It will be useful for wetland scientists and managers, and could also serve as a supplemental text on courses in wetland ecology.

    • G Davidson
    • Inglés
    Genetic Control of Insect Pests focuses on laboratory and field trials of genetic control methods of insects, which entails the use of insects to control themselves. It particularly describes species-specific and non-polluting genetic methods that have the advantage over most other methods of being efficient when the target insect is in low density, as the released insects have the capacity to search out the wild populations. Composed of nine chapters, the core parts of the book cover the mass-rearing, sterilization, and release of populations in the hope that these will mate with wild populations, leading to fertility reduction and population elimination. The book also examines techniques that use naturally existing population incompatibilities and techniques, which can result in population replacement rather than eradication with the intention to render such replacement populations harmless beforehand by genetic manipulation. This book is a valuable source of information for those who are searching for biological alternatives of insect pests control.
