During the 4th ESA-Congress, held in the Netherlands, 7-11 July 1996, a new perspective for agronomy emerged. Various contributions demonstrate the need for a new role of agronomy and its tools. In recent decades, agriculture has evolved from an activity with mainly productivity aims, into an issue conciliating environmental, agricultural, and economic and social objectives. Placing agriculture in such a broadened perspective requires a different agronomy, with new tools and approaches at a range of aggregration levels. It calls for detailed knowledge concerning the functioning, productivity and ecological relationships of agricultural plants and crops. In addition, it calls for a constant update and synthesis of existing and newly generated knowledge, the design of new ideotypes and genotypes, new production technologies, cropping systems, farming systems and agro-ecological land use systems.This proceedings book presents a set of case studies illustrating the various agronomic tools that can be used for specific agronomic questions. The case studies are grouped in sections illustrating relevant subquestions in developing an agriculture with broadened objectives. The book starts with an introductory paper on the role of agronomy in research and education in Europe. The second section deals with agricultural land use, food security and environment. This is followed by a set of papers describing experimental research and modeling approaches used to design new ideotypes of crops, including physiological properties in relation to growth factors such as radiation, CO2, temperature and water.Sustained soil fertility directly links to nutrient cycling and soil organic matter. A selected set of papers addresses the improvements in resource use efficiency and as such their contribution towards economic, environmental and agricultural objectives. The final section addresses the design of integrated and ecological arable farming systems. It highlights the role of prototyping interaction with leading-edge farmers, as promising tools to design, implement and test new farming systems.It is hoped that the activities of the European Society for Agronomy and the Proceedings of its 4th Congress will stimulate to serve the new perspectives of agronomy, i.e. to adopt ecological principles, to optimally manage the use of resources and to meet social and economic objectives.

Soft Scale Insects is intended to be a further step towards providing comprehensive information on soft scale insects. Four or five decades ago, entomologists embarking on a study on soft scale insects would have encountered a scarcity of general text books or comprehensive treatise of the family, as a starting point for their research. At the time, the available knowledge and data were either scattered among numerous articles or regional monographs or were in obsolete books. It is hoped that this volume will cover almost the entire spectrum of the knowledge on the soft scale insect family, Coccidae. This book comprises six chapters and begins by discussing the natural enemies of soft scale insects, such as pathogens like entomopathogenic fungi; predators like coccineilidae and other coleoptera; and parasitoids like encyrtidae. It then discusses issues of damage and control, including pest status of soft scale insects and coccid pests of important crops. This book will be of interest to entomologists, horticulturists, zoologists, biologists, and those involved in general agricultural research.

The Handbook of Neurolinguistics is a state-of-the-art reference and resource book; it describes current research and theory in the many subfields of neurolinguistics and its clinical application. Thorough and clearly written, the handbook provides an excellent overview of the field of neurolinguistics and its development. The book is organized into five parts covering the history of neurolinguistics, methods in clinical and experimental neurolinguistics, experimental neurolinguistics, clinical neurolinguistics, and resources in neurolinguistics. The first four parts contain a wide range of topics which discuss all important aspects of the many subfields of neurolinguistics. Also included are the relatively new and fast developing areas of research in discourse, pragmatics, and recent neuroimaging techniques. The resources section provides currently available resources, both traditional and modern. The handbook is useful to the newcomer to the field, as well as the expert searching for the latest developments in neurolinguistics.

Part II of this excellent work covers proteoglycans and mucins and deals with many more examples of glycoprotein function. It also covers glycoproteins from four more species (slime mold, snails, fish, batracians).The content of the volume is very comprehensive in that most contributors are focussed on discussing, in depth, the wealth of most recent advances in their field, referring to previous reviews of older work for background information. This method effectively produces a very wide subject coverage in a smaller number of chapters/volumes. The volume is an important information source for all glycobiologist researchers (senior investigators, post-doctoral fellows and graduate students), and as a good, comprehensive, reference text for scientists working in the life sciences.

This book aims to highlight the vigour, diversity and insight of the various cognitive science perspectives on personality and emotion. It aims also to emphasise the rigorous scientific basis for research to be found in the integration of experimental psychology with neuroscience, connectionism and the new evolutionary psychology. The contributors to this book provide a wide-ranging survey of leading-edge research topics. It is divided into three parts, on general frameworks for cognitive science, on perspectives from emotion research, and on perspectives from studies of personality traits.

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.

In this volume the entire focus is devoted to the macromolecule target specificity of DNA interactive developmental therapeutic agents of current interest. A brief introduction to DNA interactive anticancer agents is included for readers who may benefit from an overview surrounding the developments that have contributed to our general understanding of this field. The following nine chapters have been carefully chosen so that they describe topics which are at the forefront of development in DNA-targeted cancer chemotherapy. Issues that have been addressed include the mechanisms of selective DNA topoisomerase I and II poisoning by antitumor agents (Chapters 1 and 2), sequence-specific recognition of DNA by groove-binding drugs and drug-conjugates (Chapters 3 and 4), recent developments in nitrogen mustard alkylating agents and their potential use for antibody-directed enzyme-prodrug therapy (Chapter 5), nonclassical platinum anticancer complexes, including dinuclear and trans-platinum derivatives (Chapter 6), DNA cleaving antitumor chromoproteins containing reactive enediyne moieties, which exhibit interesting free-radical chemistry along with selective targeting (Chapter 7), the potential of new sequence-specific antisense and antigene therapy in oncology (Chapter 8), and finally the conceivable chemotherapeutic use of mimetics of the DNA structure, obtained by substitution of the sugar-phosphate natural chain with a peptide backbone, the so-called peptide nucleic acids (Chapter 9). Important approaches being currently investigated for selective cancer treatment, such as gene therapy and immunochemotherapy, are not discussed in this volume since they fall beyond its scope.

Both eukaryotic and prokaryotic cells depend strongly on the function of ion pumps present in their membranes. The term ion pump, synonymous with active ion-transport system, refers to a membrane-associated protein that translocates ions uphill against an electrochemical potential gradient. Primary ion pumps utilize energy derived from chemical reactions or from the absorption of light, while secondary ion pumps derive the energy for uphill movement of one ionic species from the downhill movement of another species. In the present volume, various aspects of ion pump structure, mechanism, and regulation are treated using mostly the ion-transporting ATPases as examples. One chapter has been devoted to a secondary ion pump, the Na+-Ca2+ exchanger, not only because of the vital role played by this transport system in regulation of cardiac contractility, but also because it exemplifies the interesting mechanistic and structural similarities between primary and secondary pumps.
