Book Description
« Ce livre tout en images réalisé par Jeanne Millet démontre l’importance de suivre son coeur et d’agir selon sa conscience. Elle l’a fait contre vents et marées et le résultat est magnifique et prometteur. Il nous revient à tous de penser et d’agir en fonction de ce que nous espérons pour l’avenir, et de laisser si possible un monde plus beau, plus prometteur qu’à notre arrivée.

Book Description
Préface de Jean-Louis Étienne Nouvelle édition, entièrement revue et mise à jour. Partant du principe que la taille ne doit pas être systématique mais doit résulter d’une démarche méthodique, l’auteur propose des raisonnements adaptés à la diversité des cas rencontrés sur le terrain ainsi qu’un vocabulaire, normé mais pas assujettissant. Pratique, ce guide comprend 34 analyses de cas concrets et un glossaire de près de 250 termes. Cette nouvelle édition intègre les dernières connaissances en architecture et anatomie végétales. Ce livre, fruit d’une collaboration scientifique internationale, est destiné à tous les gestionnaires d’arbres et praticiens. Largement illustré de photos et de dessins techniques, il a sa place entre les mains et dans les bibliothèques de tous ceux dont l’arbre est le métier ou la passion. L’auteur Docteur en architecture végétale, Christophe Drénou est ingénieur Recherches & Développement en biologie de l'arbre à l’Institut pour le développement forestier (CNPF-IDF). Il a conçu la méthode ARCHI, une approche pratique basée sur l'architecture des arbres pour diagnostiquer et intervenir. Il est l’auteur de plusieurs ouvrages sur les arbres et participe régulièrement à des conférences en France et à l'étranger. 320 pages, format 16 x 24 cm

Book Description
Agroforestry research is central to developing methods for the sustainable use of natural renewable resources, evolving to address the needs of the coming century. It is now necessary to consolidate the scientific gains now being made in process-oriented research and to develop a policy framework to encourage the adoption of sustainable land use practices. Agroforestry plays an important role in conserving forest resources, reducing the need for deforestation. Further, if `forest' is broadly defined as tree cover, agroforestry will also increase the proportion of woody biomass in farming landscapes. The papers selected for inclusion in Agroforestry: Science, Policy, and Practice establish agroforestry as an interdisciplinary science focused on the practical imperative of assisting farmers, forest dwellers and landscape-level planners to achieve sustainable food, fuel and timber production into the 21st century.

Book Description
Silvology is the general science of forest ecosystems, without the usual division between Man and Nature. This systematic treatment of forests intends to integrate and harmonize existing approaches with the help of systems modeling in a hierarchy of close system levels, according to criteria of biological architecture, biomass production and species composition. Scientists and practitioners will appreciate this synoptic treatment of forests and their ecology, allowing the balance of holistic and reductionist viewpoints, and the placement of phenomena and techniques. Topics covered include: - introduction of the methods, - sections on forest organisms, - a special chapter on trees, - eco-units, i.e. forest ecosystems developing after some zero-event like fire, storm or waterlogging, - silvatic mosaics built by the eco-units of different size, architecture and species composition, - a summary of silvological rules determining system's behaviour at every level, e.g. fragmentation and fusion, transfer of functions, irreversibility and process oscillation.

Book Description
Cell to Cell Signalling: From Experiments to Theoretical Models is a collection of papers from a NATO Workshop conducted in Belgium in September 1988. The book discusses nerve cells and neural networks involved in signal transfers. The works of Hodgkin and Huxley presents a prototypic combination between experimental and theoretical approaches. The book discusses the coupling process found between secretory cells that modify their behavior. The text also analyzes morphogenesis and development, and then emphasizes the pattern formation found in Drosophila and in the amphibian embryo. The text also cite examples of immunological modeling that is related to the dynamics of immune networks based on idiotypic regulation. One paper analyzes the immune dynamism of HIV infection. The text notes that hormone signaling can be attributed as responsible for intercellular communication. Another paper examines how the dominant follicle in the ovarian cycle is selected, as well as the effectiveness of hormone secretion responsible for encoding the frequency of occurrence of periodic signals. The book also discusses heart signal sources such as cardiac dynamics and the response of periodically excited cardiac cells. The text can prove valuable for practioners in the field of neurology and cardiovascular medicine, and for researchers in molecular biology and molecular chemistry.

Book Description
The worlds synthesized in the cyberspaces of networked computers are the theme of Cyberworlds. Cyberspaces have come into prominence with the de velopment of the Internet and are expected to expand drastically with the emergence of national and international information systems. The purpose is to discover the architecture and design of cy of the book Cyberworlds berworlds by synthesizing worlds in cyberspaces. The underlying philosophy is crucial to the success of the architecture, and an initial effort is made to delineate it at the beginning of the book. The book's topics are selected to clarify the issues of the philosophy, architecture, and design of cyberworlds through a wide variety of case studies. The approach presented in the book is thus characterized as synthetic rather than analytic. There already are numbers of books with observations and analyses of cyberworlds. They warn of the danger of widespread crimes and accidents in the cyberworlds, for instance. Without a philosophy and methodologies of how to architecturally design and synthesize the cyber worlds, the worlds in cyberspaces tend to be arbitrarily extended, disordered, and, in extreme cases, criminal. This book is intended to benefit readers by providing them with a possible direction to take in deciding how to synthesize worlds in cyberspaces. Cre ating new worlds in new spaces with almost unlimited dimension and scale is an immense challenge. In principle, anyone at any moment can participate in the creation. The book serves as a creator's reference and also as a design guidebook.

Book Description
This book provides an identification system permitting recognition of plant families in all seasons by means of morphological and macroanatomical features which are easily observable, such as bark, exudates, stems and leaves characters. Studies of forest vegetation may differ in their underlying objectives, but they all require taxonomic knowledge. The process of taxonomy begins with an inventory of the flora, which has been based to a large extent on reproduction-related organs, such as flowers and fruits. But, those are often difficult to observe and may not exist in the field at a given time. Unlike most such guides or keys, this book can be used anywhere in the tropics and provides, in a straightforward two or three-step process, identification to the level of families, which are now circumscribed according to molecular as well as morphological characters in the universally accepted scheme of the Angiosperm Phylogeny Group. Plant architecture is not a prerequisite theme for plant identification; however, we think that an introduction to this subject is not out of place in this book (architectural traits are taxonomically sound): it is now time for botanists working in the tropics to have an idea on how the whole organism keeps growing. Within the family accounts, there is information concerning important economic plants with notes on the larger genera and, particularly helpfully, discussion of families readily confused and how to separate them. Descriptions of the families rely on short diagnosis bolstered by many photographic pictures, lines drawings and extracts from the author’s field books, all showing features of plants as they are found in the forest.
