  • Idiotypes

    • 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.

  • Coactive Forest Management

    • 1 Edición
    • Bozzano G Luisa
    • Inglés
    This book provides a theoretical basis and a collection of management science tools that account for the interactions between different components of a managed forest ecosystem. Accounting for these interactions is the rapid evolution of forest management away from a traditional agricultural commodities production problem to a multi-output problem that gives equivalent emphasis to nonmarket goods and the health of forest ecosystem itself. The book is a comprehensive theoretical demonstration of the breakdown of traditional benefit/cost analysis in the presence of forest ecosystem (or demand) inteactions and is followed by a set of management science (optimization) procedures that address these interactions and better capture the ecosystem function.

    A change in land use has been found to alter the components of the hydrological cycle through its effects on evapotranspiration. This influences planning and management of water resources. The Workshop, from which this volume was derived, was organized in this context to discuss processes and techniques relevant to estimating evapotranspiration of communities ranging from agricultural to forested lands. Its objectives were to provide a forum for exchange of ideas, to gather up-to-date information on the state of the art, and to identify priority areas for future research.The eighteen papers in this volume have been selected from those presented at the Workshop on the basis of technical quality and subject matter coverage and result in a valuable contribution to our current understanding of evapotranspiration.

    • 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.

  • Agriculture in Dry Lands

    Principles and Practice

    • Inglés
    Throughout history, man has, by over-use, consistently reduced the productive capacity of dry lands. This degradation of one-third of the land area of the globe is, unfortunately, increasing. In recent years, world interest has turned to the problems of pollution of the environment and the impending food shortage as world population grows explosively. Thus the attention of international and other agricultural bodies has turned to the need for preserving and developing more effectively the agricultural potential of these areas.This book provides a comprehensive review of present knowledge of the agriculture of dry lands, with special emphasis on measures for conserving their natural resources. Management practices are described which aim at optimizing productivity of rainfed and irrigated agriculture without adverse effects on sustainability. Land use in the dry regions, and its evolution throughout history is described and analysed, and the lessons to be learnt from destructive technologies are stressed. In particular, current proposals for an alternative agriculture are discussed and their justification is questioned. This is a generalist work, which specialists can also find interesting, not only in their own discipline but as a concise way of acquainting themselves with the state-of-the-art in associated fields. Increasing specialisation with each discipline using its own vocabulary leads inevitably to communication problems, and the need for multi-disciplinary teams makes inter-discipline communication indispensible.

    • Inglés
    Senescence and Aging in Plants reviews the state of knowledge in the processes involved in plant senescence and aging. The book begins by discussing the emergence of senescence as a concept; experimental analysis of senescence; and patterns of senescence. It then examines membrane deterioration during senescence; photosynthesis in relation to leaf senescence; senescence of detached plant organs; changing patterns of nucleic acid and protein synthesis during senescence; and degradative and associated assimilatory aspects of nitrogen removal. This is followed by chapters on aspects of ethylene that may impinge upon its role in promoting senescence of higher plants; the role of cytokinins in plant senescence; the promoters and retardants of senescence; and the role of calcium in plant senescence. The concept of whole plant senescence is discussed, which can be subdivided into patterns, correlative controls, cessation of vegetative growth, declining assimilatory processes, assimilate partitioning, and hormonal controls. The final chapters cover the deterioration of cellular membranes during the plant aging process and seed aging.
