Taschenbuch. Zustand: Neu. Neuware - Today, as much of the world seeks to reduce dependence on fossil fuels, energy companies and nations alike are turning once again to our oldest renewable energy resourcewood. Both developing and industrialized countries are increasing their use of wood biomass as a direct substitute for fossil fuels for heating and producing electricity. And research is well underway on converting wood to a liquid fuel, which could lessen the reliance on oil. But using wood for bioenergy and biofuels is not without its issues. Of primary concern is if the wood needed for those purposes can be secured on a sustainable basis. And without sizeable subsidies, it is not yet cost effective to convert wood to liquid fuel at a commercial scale. Other issues include the relation between biomass harvesting and carbon emissions, evaluating supply chain systems for energy markets, and the effect subsidies can have on the price of wood. By reviewing the historical context and contemporary issues surrounding this topic, Wood for Bioenergy provides a primer for teachers, policymakers, energy producers, landowners, forest managers, and journalists on this critical energy source. This book was published with support from the Plum Creek Foundation, U.S. Forest Service Research, Forest Investment Associates, National Alliance of Forest Owners, Potlatch Corporation, Price Biostock, the Westervelt Company, and the Lynn W. Day Endowment for Forest History Publications.…

Zustand: MOLTO BUONO. Londra-New York, Elseviere Applied Science cm.14x21, pp.282, legatura editoriale copertina figurata. Synthetic polymers make excellent specimens for light microscopy. Despite this, the use of the technique, at least in its advanced forms, is not so widespread as might be expected. Although reliable and relevant data are difficult to find and quantify, it seems that in other fields of materials science and technology there is a greater readiness to tum to the microscope in research, in industrial problem solving, or for quality assessment and control. It also seems that the reasons for the present situation are partly historical, partly the result of the structure of the plastics and rubber industries, and partly the education and training background of senior staff who tend to be chemistry or engineering based. In neither field does light microscopy feature strongly in the basic training. The primary aim of this book is to provide some insight into the range oflight microscopy techniques applicable to polymeric specimens, and to highlight typical applications to commercial polymers and polymer products. Where appropriate, the optical techniques involved are discussed in some detail. However, it has not been the intention to produce a light microscopy textbook dealing with the principles and design of the basic instrument. Many such texts are available, and selected examples are cited in the reference list at the end of most chapters.…
