Modern forest products research had its start hardly fifty years ago. Today we are in a position to apply the title "wood science" to the field of wood technology that is based on scientific investigation, theoretical as well as experimental. It is this research that fosters new uses for wood as a raw material and that creates the foundation for new industries for the manufacture of wood-base materials such as plywood, laminated products, particle and fiber board and sand wich construction. Wood technology in its broadest sense combines the disciplines of wood anatomy, biology, chemistry, physics and mechanical technology. It is through this interdisciplinary approach that progress has been made in wood seasoning, wood preservation methods, wood machining, surfacing and gluing, and in the many other processes applied in its utilization. In 1936 the senior author published a book entitled, "Technologie des Holzes", which was a first approach to a universal reference book on wood technology. The first edition of Volume I of the Textbook of Wood Technology, co-authored by H. P. BROWN, A. J. P AN SHIN , and C. C. FORSAITH, was published in 1948. An indication of the rapid development of this field can be gained from the fact that the second edition of "Technologie des Holzes und der Holzwerkstoffe", completely revised, was needed by 1951. It contains 2233 pages compared with the 764 pages of the 1936 edition.
Macrofungi have significant importance in human health, particularly in nutrition, medicine, pharmaceuticals, agriculture and industries. They occupy a variety of ecosystems such as terrestrial (agricultural lands, forests and deserts), freshwater (bogs and marshes) and maritime (mangroves and coastal sand dunes) habitats. Their ecosystem services like nutrition (humans and animals), medicinal pursuits (antibiotics and pharmaceuticals) and bioremediation (degradation of xenobiotics and insect control) potential are dependent on their diversity and ecological conditions. Macrofungal ecology serves as the basis for nutraceutical values, agricultural benefits, plant productivity, environmental protection and industrially valued biocomposites. This book focuses on various aspects of macrofungal distribution in diverse habitats, participation in organic matter decomposition, ectomycorrhizal associations and participation in biogeochemical cycles. This book reviews the current developments in macrofungal ecology in different habitats and their benefits. Due to the topics dealt with on macrofungal diversity, distribution, dynamics, lifestyles, ecosystem or substrate preferences and ecosystem services, this book is valuable to mycologists, botanists, zoologists, ecologists, foresters, geneticists, agronomists and field biologists.
Tree Pathology: A Short Introduction is a compilation of texts about some of the significant stress factors that are capable of inducing tree injuries and diseases. It also provides an overview of some of the examples of the damage caused by each stress factors or agents. In addition, existing hypotheses related to the mechanism by which each agent causes abnormal tree physiology are reviewed. As an introduction, the book provides a discussion on the agents, mechanisms, and control of the pathological stresses of forest trees. It also offers specific examples of forest tree species, mostly from the northeastern portion of the United States, as well as examples of citrus and other fruit or jut tree species. The book then discusses all injury and disease agents including their taxonomy, morphology, physiology, and ecology. It also presents the different mechanisms of the injury and disease, control possibilities on mitigating disease influences of plants, and specific utility of the various procedures used in forest tree disease control. The materials presented in the book are based from the numerous published texts, journal articles, and research reports.
Wood has played a major role throughout human history. Strong and versatile, the earliest humans used wood to make shelters, cook food, construct tools, build boats, and make weapons. Recently, scientists, politicians, and economists have renewed their interest in wood because of its unique properties, aesthetics, availability, abundance, and perhaps most important of all, its renewability. However, wood will not reach its highest use potential until we fully describe it, understand the mechanisms that control its performance properties, and, finally, are able to manipulate those properties to give us the desired performance we seek. The Handbook of Wood Chemistry and Wood Composites analyzes the chemical composition and physical properties of wood cellulose and its response to natural processes of degradation. It describes safe and effective chemical modifications to strengthen wood against biological, chemical, and mechanical degradation without using toxic, leachable, or corrosive chemicals. Expert researchers provide insightful analyses of the types of chemical modifications applied to polymer cell walls in wood. They emphasize the mechanisms of reaction involved and resulting changes in performance properties including modifications that increase water repellency, fire retardancy, and resistance to ultraviolet light, heat, moisture, mold, and other biological organisms. The text also explores modifications that increase mechanical strength, such as lumen fill, monomer polymer penetration, and plasticization. The Handbook of Wood Chemistry and Wood Composites concludes with the latest applications, such as adhesives, geotextiles, and sorbents, and future trends in the use of wood-based composites in terms of sustainable agriculture, biodegradability and recycling, and economics. Incorporating decades of teaching experience, the editor of this handbook is well-attuned to educational demands as well as industry standards and research trends.
