Litter Decomposition describes one of the most important processes in the biosphere - the decay of organic matter. It focuses on the decomposition process of foliar litter in the terrestrial systems of boreal and temperate forests due to the greater amount of data from those biomes. The availability of several long-term studies from these forest types allows a more in-depth approach to the later stages of decomposition and humus formation. Differences between the decay of woody matter and foliar litter is discussed in detail and a different pattern for decomposition is introduced.
Are we alone in the universe? The search for extraterrestrial intelligence (SETI) has been given fresh impetus in recent years following developments in space science which go beyond speculation. The evidence that many stars are accompanied by planets, the detection of organic material in the circumstellar disks of which planets are created, and claims regarding microfossils on Martian meteorites have all led to many new empirical searches. Against the background of these dramatic new developments in science,SETIcritically evalutes claims concerning the status of SETI as a genuine scientific research program and examines the attempts to establish contact with other intelligent life forms in the past thirty years. David Lamb also asseses competing theories on the origin of life on Earth, discoveries of ex-solar planets and proposals for space colonies as well as the technical and ethical issues bound up with them. Most importantly, he considers the benefits and drawbacks of communicationwith new life forms: how we should communicate and whether we should.
The "Encyclopedia of Organic, Sustainable, and Local Food" pulls together a fascinating array of diverse, interdisciplinary topics to provide a thorough overview of our current alternative food system. With increasing attention focused on organic and local food, many people are attracted to these sustainable food choices. Yet despite its popularity, there are misconceptions and a general lack of understanding about organic and local food.
This encyclopedia illuminates social concerns, economic trends, policy influences, and ecological terms to provide a comprehensive overview. Contributions from expert authors from government agencies, research universities, and private organizations provide key information on each of these relevant topics. Eating is a basic human activity, yet many people do not know where their food comes from. This book helps readers fill the gap between the trendy and the factual.
Why has the clean, limitless energy promised by fusion always seemed just out of reach?
Search for the Ultimate Energy Source: A History of the U.S. Fusion Energy Program, explains the fundamentals and concepts behind fusion power, and traces the development of fusion historically by decade-covering its history as dictated by US government policies, its major successes, and its prognosis for the future. The reader will gain an understanding of how the development of fusion has been shaped by changing government priorities as well as other hurdles currently facing realization of fusion power.
Advance Praise for Search for the Ultimate Energy Source:
"Dr. Dean has been uniquely involved in world fusion research for decades and, in this book, describes the complicated realities like few others possibly could."
-Robert L. Hirsch, a former director of the US fusion program, an Assistant Administrator of the US Energy Research and Development Administration (ERDA); an executive at Exxon, Arco, and the Electric Power Research Institute (EPRI); and lead author of the book The Impending World Energy Mess (Apogee Prime Books, 2009).
"In this book, Dr. Dean provides the many reasons why fusion has progressed more slowly than many had hoped. Budget is usually cited as the culprit, but policy is equally to blame. Facilities have been closed down before their jobs were done-or in some cases, even started. It seems this situation has become endemic in fusion, and if one thinks about it, in other nationally important Science and Technology initiatives as well."
-William R. Ellis, a former scientist at Los Alamos National Laboratory, Associate Director of Research at the US Naval Research Laboratory, a vice president at Ebasco Services and at Raytheon, and chair of the US ITER Industry Council and the US ITER Industrial Consortium.
