Available in PDF, EPUB and Kindle. Book excerpt: This book addresses core questions about the role of materials in general and of wood in particular in the construction of string instruments used in the modern symphony orchestra – violins, violas, cellos and basses. Further attention is given to materials for classical guitars, harps, harpsichords and pianos. While some of the approaches discussed are traditional, most of them depend upon new scientific approaches to the study of the structure of materials, such as for example wood cell structure, which is visible only using modern high resolution microscopic techniques. Many examples of modern and classical instruments are examined, together with the relevance of classical techniques for the treatment of wood. Composite materials, especially designed for soundboards could be a good substitute for some traditional wood species. The body and soundboard of the instrument are of major importance for their acoustical properties, but the study also examines traditional and new wood species used for items such as bows, the instrument neck, string pegs, etc. Wood species’ properties for musical instruments and growth origins of woods used by great makers such as Antonio Stradivari are examined and compared with more recently grown woods available to current makers. The role of varnish in the appearance and acoustics of the final instrument is also discussed, since it has often been proposed as a ‘secret ingredient’ used by great makers. Aspects related to strings are commented.As well as discussing these subjects, with many illustrations from classical and contemporary instruments, the book gives attention to conservation and restoration of old instruments and the physical results of these techniques. There is also discussion of the current value of old instruments both for modern performances and as works of art having great monetary value.The book will be of interest and value to researchers, advanced students, music historians, and contemporary string instrument makers. Musicians in general, particularly those playing string instruments, will also find its revelations fascinating. It will also attract the attention of those using wood for a variety of other purposes, for its use in musical instruments uncovers many of its fundamental features. Professor Neville H.

Download or read book Ecosystem Services from Forest Landscapes written by Ajith H. Perera and published by Springer. This book was released on 2018-03-22 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, the topic of forest ecosystem services has attracted the attention of researchers, land managers, and policy makers around the globe. The services rendered by forest ecosystems range from intrinsic to anthropocentric benefits that are typically grouped as provisioning, regulating, supporting, and cultural. The research efforts, assessments, and attempts to manage forest ecosystems for their sustained services are now widely published in scientific literature. This volume focuses on broad-scale aspects of forest ecosystem services, beyond individual stands to large landscapes. In doing so, it illustrates the conceptual and practical opportunities as well as challenges involved with planning for forest ecosystem services across landscapes, regions, and nations. The goal here is to broaden the scope of land use planning through the adoption of a landscape-scale approach. Even though this approach is complex and involves multiple ecological, social, cultural, economic, and political dimensions, the landscape perspective appears to offer the best opportunity for a sustained provision of forest ecosystem services.

This book was released on 2012-08-22 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a solid body of the current state of knowledge on the various themes and activities in agroforestry worldwide. It is organized into three sections: the Introduction section consists of the summaries of six keynote speeches at the 2nd World Congress of Agroforestry held in Nairobi, Kenya, in 2009; that is followed by two sections of peer-reviewed thematic chapters grouped as “Global Perspectives” (seven chapters) and “Regional Perspectives” (eleven chapters), authored by professional leaders in their respective agroforestry-related fields worldwide. A total of 130 professionals from institutions in 33 countries in both developing and the industrialized temperate regions of the world contributed to the book as chapter authors and/or reviewers. Thus, the book presents a comprehensive and authoritative account of the global picture of agroforestry today.
Download or read book Drying Hardwood Lumber written by Joseph Denig and published by . This book was released on 2000 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drying Hardwood Lumber focuses on common methods for drying lumber of different thickness, with minimal drying defects, for high quality applications. This manual also includes predrying treatments that, when part of an overall quality-oriented drying system, reduce defects and improve drying quality, especially of oak lumber. Special attention is given to drying white wood, such as hard maple and ash, without sticker shadow or other discoloration. Several special drying methods, such as solar drying, are described, and proper techniques for storing dried lumber are discussed. Suggestions are provided for ways to economize on drying costs by reducing drying time and energy demands when feasible. Each chapter is accompanied by a list of references. Some references are cited in the chapter; others are listed as additional sources of information.
Download or read book Peatland Forestry written by Eero Paavilainen and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a review and synthesis of boreal mire ecosystems including peat soil properties, mire hydrology, carbon and nutrient cycling, and classification of mire sites. The emphasis, however, is on peatland forests as a renewable natural resource. The approach originated in northern Europe, because there, especially in Finland, operational scale forest drainage has a long tradition based on research aiming to maintain and increase wood production on peatlands. Whenever relevant, a closer look is also given to other countries in Europe, Canada, and the USA. The results of recent studies on different environmental effects of peatland forestry are also discussed in detail.
Download or read book Wood Water Relations written by Christen Skaar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is formed in an essentially water-saturated environment in the living tree, and the cell wall remains in this state until the water flow from the roots is interrupted, such as by felling the tree. The wood then begins to lose most of its moisture by drying, resulting in changes in most of its physical properties. These changes, and their relationship to the environment to which the wood is subsequently ex posed, are the subject of this book. The text consists of six chapters. The first chapter discusses cer tain empirical relationships between wood and water, methods of measuring wood moisture content, factors which affect its equilib rium moisture content, and the effect of moisture content on wood strength. The second chapter treats the thermodynamics of moisture sorption by wood, inc1uding enthalpy, entropy, and free energy changes. The third chapter discusses some of the theories which have been proposed to explain the sorption isotherms for hygroscopic ma terials such as wood. Chapter 4 considers hygroexpansion or the shrinking and swelling of wood associated with moisture change. Chapter 5 is concerned with how moisture moves through the cell wall of wood in response to both moisture and temperature gradients. The sixth and final chapter discusses the theoretical and practical aspects of the electrical resistance and dielectric properties of wood, in c1uding the principles involved in their application in electrical moisture meters.
Download or read book Sustainable Forest Management in a Changing World a European Perspective written by Peter Spathelf and published by Springer Science & Business Media. This book was released on 2009-12-04 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yet another book on the topic of ‘Sustainable Forest Management’ can only be justified by new information that is of direct relevance. The contents of this volume concentrate on the very latest factors and developments, thus, hopefully, contributing both to the book’s attractiveness and to closing gaps in the discipline’s database. This book is written for researchers in the field of forest management, international forestry, and climate change-related issues, legal and policy advisors, as well as for managers of private companies who deal with SFM. The authors of the various sections are scientists in the field of forestry and other environmental sciences. They represent different institutions, mainly universities and research agencies in Germany, but also high-level international institutions in development co-operation, such as the World Bank, FAO, and IIASA. The scope of the book is to refresh the meanings and perceptions of SFM against the background of the rapid changes in our natural and social environment. Climate change and the rapid increase of atmospheric CO concentration is a global process 2 with negative impacts of different kinds, among others on natural ecosystems such as forests. A crucial issue therefore is how forest management can contribute to forest conservation in light of changing climatic conditions. Moreover, policy changes such as the introduction of certification schemes and the new emphasis laid on Non-Wood Forest Products justify the re-evaluation of the role of SFM in delivering ecological goods and services from our forests.
