Vers et virus
Cet ouvrage s'adresse aux informaticiens avec une nouvelle vision du phénomène virus : celle du chasseur et non celle du hacker. Son but n'est pas d'expliquer comment sont conçus les virus, mais comment ils fonctionnent et comment les combattre. L'entrée en matière retrace l'histoire des virus informatiques, histoire fertile en anecdotes et rebondissements. Vient ensuite une déclinaison des différents types de virus avec leurs cibles et leurs attributs. Les virus programmes et les vers sont expliqués très en détail puisque l'auteur présente des visualisations de fichiers en hexadécimal pour faire comprendre aux lecteurs la structure interne des fichiers modernes et la trace qu'y laissent les virus. Viennent ensuite la protection anti-virale dans ses aspects théoriques et méthodologiques, puis les critères de choix d'un bon anti-virus. Cet ouvrage se termine par une analyse de l'évolution de la criminalité informatique et de ses motivations.

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
Plant Virus and Viroid Diseases in the Tropics
Around the globe, besides fungal and bacterial diseases, both virus and viroid diseases have acquired greater importance in the realm of plant pathology and call for effective management measures as they are responsible for heavy yield losses and are a matter of vital importance and concern to farmers, horticulturists, gardeners and foresters. Understanding disease epidemiology is of vital importance for formulating viable disease management practices in a given agro-ecosystem. The development and progress of plant disease epidemics are variable from region to region. Epidemiology is not a static process, but rather a dynamic course that varies with a change in the ecology, host, vector and virus systems.
The Coming Plague
After four decades of assuming that the conquest of all infectous diseases was imminent, people on all continents now find themselves besieged by AIDS, drug-resistant tuberculosis, cholera that defies chlorine water treatment, and exotic viruses that can kill in a matter of hours. Based on extensive interviews with leading experts in virology, molecular biology, disease ecology and medicine, as well as field research in sub-Saharan Africa, Western Euope, Central America and the United States, The Coming Plague takes readers from the savannas of eastern Bolivia to the rain forests of northen Zaire on a harrowing, fifty year journey through our battles with the microbes, and tells us what must be done to prevent the coming plague.
Design and Validation of Computer Protocols
This volume discusses the fundamental problems of designing logically consistent methods of communication between multiple computer processes. Standard protocol design problems, such as error control and flow control, are covered in detail, but also structured design methods and the construction of formal validation models. The book contains complete listings and explanations of new protocol validation and design tool called SPIN. Author is in charge of protocol design at Bell Labs. Professionals who bought Tanenbaum's COMPUTER NETWORKS, 2/E and Comer's TCP/IP will buy this. This is the first book to cover automated protocol design and validation tools extensively.
Stress Appraisal and Coping
The reissue of a classic work, now with a foreword by Daniel Goleman! Here is a monumental work that continues in the tradition pioneered by co-author Richard Lazarus in his classic book Psychological Stress and the Coping Process. Dr. Lazarus and his collaborator, Dr. Susan Folkman, present here a detailed theory of psychological stress, building on the concepts of cognitive appraisal and coping which have become major themes of theory and investigation. As an integrative theoretical analysis, this volume pulls together two decades of research and thought on issues in behavioral medicine, emotion, stress management, treatment, and life span development. A selective review of the most pertinent literature is included in each chapter. The total reference listing for the book extends to 60 pages. This work is necessarily multidisciplinary, reflecting the many dimensions of stress-related problems and their situation within a complex social context. While the emphasis is on psychological aspects of stress, the book is oriented towards professionals in various disciplines, as well as advanced students and educated laypersons. The intended audience ranges from psychiatrists, clinical psychologists, nurses, and social workers to sociologists, anthropologists, medical researchers, and physiologists.

Small scale Poultry Production
This technical guide promotes sustainable small-scale, family-based poultry production. It gives a comprehensive review of all aspects of small-scale poultry production in developing countries and includes sections on feeding and nutrition, housing, general husbandry and flocks health. Regional differences in health practices are also described. The guide provides the technical and scientific "building blocks" needed to develop sustainable programs for small-scale poultry production. It will be of practical value to those keeping or planning to keep poultry and as a valuable technical reference for poultry specialists, researchers, students and those interested in broader rural development issues.--Publisher's description.
