Download or read book DendroScan written by Thierry Marie Louis Varem-Sanders and published by UBC Press. This book was released on 1996 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: DendroScan is a system developed for measuring tree-ring width and density. Tree rings contain a record of diameter growth and carbon storage in the tree trunk. The width of the rings can be measured using a variety of systems, but the density (carbon storage) is most easily measured by X-ray densitometry. The DendroScan system eables the user to meaure both tree ring width and density, or just ring widths. The system can use prepared wood samples (for ring widths only) or X-ray images. DendroScan is fully described, with discussion of sample preparation, calibration procedures, and data analysis. Information and instructions for the user are included. The DendroScan program is enclosed on a DOS-formatted disk, along with a precalibrated precision wedge for converting X-ray images to density.

This book was released on 2007-01-19 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a guide to imaging techniques for sedimentologists, paleolimnologists, paleoceanographers and microscopists involved in paleoenvironmental reconstruction. Case studies illustrate the range of information obtainable from different sediments (marine, lacustrine, aeolian) and different types of samples (cores, embedded blocks, microscopic slides) using different regions of the electromagnetic spectrum (visible, UV, IR, X-ray). Includes comprehensive protocols, guidelines, and recommendations for the use of low cost image analysis techniques.

Download or read book Balancing Act written by J P Hamish Kimmins and published by UBC Press. This book was released on 2011-01-01 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, there has been much debate over the environmental impact of forestry. People are justifiably concerned about what is happening to the local and global forest environments, but they are also confused by the polarized rhetoric that has characterized both sides of the debate. In Balancing Act, Hamish Kimmins calls for a balanced, more objective approach to forestry issues in order to bridge the gap between the most extreme opponents in the debate. He suggests that we need to begin with a common understanding of what forestry is about and how forest ecosystems work. He outlines the scientific and ecological aspects of the major environmental issues facing British Columbia and the world today, arguing that we need to disentangle the scientific from the value-based social aspects of these questions. He also contends that much of the current debate about forests and their management ignores the time dimension of ecosystems, and he calls for a more dynamic view of current environmental issues in forestry -- one that accounts for change. The first few chapters provide an outline of the basic principles of forestry and ecology, and subsequent chapters discuss the major environmental issues facing forestry in the 1990s. These include clearcutting, slashburning, management chemicals, old growth, biological diversity, 'new forestry, ' climate change, acid rain, the comparison between temperate and tropical forestry, and long-term decisions in forestry. Balancing Act is essential reading for those who are searching for an objective, accurate, and readable evaluation of the issues at the heart of the forestry/environment debate. By emphasizing that forests are not static but change over time, Kimmins adds an important, often ignored, dimension to the discussion. Only by understanding all the intricacies of the ecosystems can we learn to manage our forests in a sustainable fashion.

Book excerpt: A solarpunk masterpiece from a writer who champions a positive, inclusive and deep-thinking version of future possibilities. The Pulldogs leave Rome to embrace a new condition: leaving no trace of their passage, they shape a new challenging lifestyle: wandering around the world as neo-nomads to spread their solarpunk way of living and to engage on a never-ending mission to save endangered human cultures with nanites. But the vision of Alan and Nicolas about how the Pulldogs should live collide, and as a consequence, they split in two groups: one goes North to live in the beautiful wilderness of Siberia and Mongolia, while the other goes South to save the Dogon tribe from a possible extinction due to climate change in Central Africa. But at the end everybody - including a new generation of Pulldogs - will have to come back to Rome, where their incredible transformation started many years before. Sequel to the celebrated The Roamers.

This book was released on 2012-12-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exchange of information in the field of earth sciences is increasingly needed to stay informed about advances. However, the continuous increase in the number of journal articles and books is very noticeable, while the available time to keep up is decreasing. Such a large flow of information commonly necessitates professionals to search selec tively for material and special publications in one's sub-discipline that have more specific coverage. In addition to surveying research needs, earth scientists working in a pure or applied research environment collect and produce information that often is of interest to the much larger group of industry-employed geologists and geophysicists, to professionals employed by agencies, and to students. To accommodate this exchange of needed information, Springer-Verlag is launching a monograph series entitled "Frontiers in Sedimentary Geology." This series will cover a number of subjects related to sediments and sedimentary rocks in a manner that both the researcher and the industrially oriented earth scientist can use constructively. Pub lications in this monograph series may fit one or more of the following main categories: Topical A topical subject will cover either the different aspects of a selected environment of deposition, or present a world tour of a particular depositional environment to dem onstrate its variability and its commonalities. The author(s) or editor(s) accepts the responsibility to guide the reader as to the state of knowledge, rather than providing a set of independent chapters.
