Primary Energy: Present Status and Future Perspectives

The enormous public interest of specialists as well as of engaged and concerned citizens in the energy problem can be understood in view of the fact that the future of national and world-wide economy depends on the availability of sufficient primary energy. The questions arising are: which forms of primary energy exist principally? by what means and at what cost can they be brought to useful application? and what is their possible role in the present and future energy scenario? Another reason which may not be so obvious, but which eventually may prove to be of great importance as far as public acceptance of energy technologies is con­ cerned, lies in the fact that the existing conscious or subconscious fears arising from confrontation with scientific and technological progress - to which even for the educated layman intellectual access is diffi­ cult - have been sublimated onto the energy problem and especially onto the problem of nuclear energy. Un­ like other developments, the emergence of nuclear ener­ gy has brought to our notice the ambivalence of ad­ vancing science and technology, which may either be used peacefully or misused militarily. Nuclear energy can help to overcome the increasing hunger for energy in the world, but it can also lead to the extinction of human life from the surface of this plant. More and more, mankind is confronted with chances and risks of new discoveries.

Rivers: Form and Process in Alluvial Channels (Routledge Revivals)

Originally published in 1982, this book presents a detailed review of alluvial river form and process and integrates the distinct but related approaches of geomorphologists, geologists and engineers to the subject. It outlines the environmental catchment factors that control the development of channel equilibrium and provides a detailed account of the sediment transport processes that represent the physical mechanisms by which channel adjustment occurs. Where possible it evaluates theoretical analyses in the context of the empirical evidence. Rivers should prove a valuable textbook for geomorphology students on advanced undergraduate courses on river behaviour and will also be of interest to students of hydraulics and sedimentology and to those concerned with civil and environmental engineering, river management and channel design, maintenance and management in the water industry

Sacred Summits: The Carstensz Pyramid, Kangchenjunga and Gauri Sankar

Mountaintops have long been seen as sacred places, home to gods and dreams. In one climbing year Peter Boardman visited three very different sacred mountains. He began on the South Face of the Carstensz Pyramid in New Guinea. This is the highest point between the Andes and the Himalaya, and one of the most inaccessible, rising above thick jungle inhabited by warring Stone Age tribes.During the spring Boardman made a four-man, oxygen-free attempt on the world's third highest peak, Kangchenjunga. Hurricane-force winds beat back their first two bids on the unclimbed North Ridge, but they eventually stood within feet of the summit – leaving the final few yards untrodden in deference to the inhabiting deity. In October, he climbed the mountain most sacred to the Sherpas: the twin-summited Gauri Sankar. Renowned for its technical difficulty and spectacular profile, it is aptly dubbed the Eiger of the Himalaya and Boardman's first ascent took a gruelling twenty-three days.Three sacred mountains, three very different expeditions, all superbly captured by Boardman in Sacred Summits, his second book, first published shortly after his death in 1982. Combining the excitement of extreme climbing with acute observation of life in the mountains, this is an amusing, dramatic, poignant and thought-provoking book.Peter Boardman and Joe Tasker died on Everest in 1982, whilst attempting a new and unclimbed line. Both men were superb mountaineers and talented writers. Their literary legacy lives on through the Boardman Tasker Prize for Mountain Literature, established by family and friends in 1983 and presented annually to the author or co-authors of an original work which has made an outstanding contribution to mountain literature.

Savage Arena: K2, Changabang and the North Face of the Eiger

I could never again maintain that I was caught up in this game unwillingly. I knew now what I wanted to do. Willingly would I accept the hardship and fear, the discipline and the sacrifices, if only I could be given back the chance to climb that mountain.' Joe Tasker lies, struck down by a tooth abscess, in a damp, bug-infested room in the Himalaya, wondering if he will be well enough to climb Dunagiri, his first venture to the 'big' mountains. He is there with Dick Renshaw to attempt to make a two-man ascent of the Peak - one of the first true Alpine-style expeditions to the Greater Ranges; an attempt that forms part of this tale of adventure in the savage vertical arena of hostile mountains. Joe Tasker was one of Britain's foremost mountaineers. A pioneer of lightweight mountaineering and a superbly gifted writer, in Savage Arena he vividly describes his participation in the first British winter ascent of the North Face of the Eiger; his first ascent of the West Wall of Changabang with Peter Boardman - considered to be a preposterous plan by the established climbing world; the first ascent of the North Ridge of Kangchenjunga; and his two unsuccessful attempts to climb K2, the second highest mountain in the world. This is a story of single-minded determination, strength and courage in a pursuit which owes much of its value and compulsion to the risks entailed - risks which often stimulate superlative performances. It is also a story of the stresses, strains and tensions of living in constant anxiety, often with only one other person, for long periods in which one is never far from moments of terror, and of the close and vital human relationships which spring from those circumstances. It is a moving, exciting and inspirational book about the adventuring spirit which seeks endless new climbing challenges to face, alluring problems to solve and difficulties to overcome, for it is not reaching the summit which is important, but the journey to it. Joe Tasker and Peter Boardman died on Everest in 1982, while attempting a new and unclimbed line. Both men were superb mountaineers and talented writers. Tasker's first book, Everest the Cruel Way, was first published in 1981. Savage Arena, his second book, was completed just before he left for Everest. Both books have become mountaineering classi. The literary legacy of Tasker and Boardman lives on through the Boardman Tasker Prize for Mountain Literature, established by family and friends in 1983 and presented annually to the author or co-authors of an original work which has made an outstanding contribution to mountain literature.

U.S.-Japanese Agricultural Trade Relations (Routledge Revivals)

First published in 1982, the editors and authors of this book examine the United States’ 1973 embargo on the export of soybeans and its effects on U.S.-Japanese relations. Although eventually shipment of soybeans to Japan resumed, the embargo temporarily soured the friendly relations of the two democracies. This book, prepared by a group of Japanese and U.S. scholars, demonstrates how trade relations between the two countries are affected by their internal political situations and by the nature of their respective agricultural industries. U.S.-Japanese Agricultural Trade Relations will be valuable to scholars, policy makers, and others interested in agricultural trade. It should be particularly useful in courses on international trade and on agricultural policy.

Ark on the Move

'Even the most cautious of travellers would, I think, be thrilled at the idea of visiting a remote tropical island. There seems to be something about tropical islands that stirs the blood of even the most unadventurous souls.' Lying in the Indian Ocean, the islands of Mauritius and Madagascar - where millions of years of evolutionary isolation created a flora and fauna unique in the world - provide the exotic setting for Gerald Durrell's expeditionary rescue work with animals. In his personal and delightful way he entertains, educates and makes a dramatic appeal to us all about the distressing state of these beautiful and endangered species around the world and shows us the serious consequences to life and its future on this earth. This exciting journey also inspired an international television series based on the author's rescue and breeding operations.

Assay of Calcium-regulating Hormones

The ability to measure accurately the hormones regulating calcium homeosta­ sis is the fundamental first step toward understanding the roles these hormones play in health and disease. Techniques for such measurements have only been available for the past 10 years or so and remain in a state of rapid development. Sensitive parathyroid hormone (PTH) radioimmunoassays appeared in the early 1970s, and with them came a whole new appreciation for the prevalence and implications of hyperparathyroidism, primary or secondary, in the popu­ lation. The calcitonin (CT) radioimmunoassay came later and achieved rapid success in the. diagnosis of a previously poorly understood cancer, medullary carcinoma of the thyroid, frequently associated with the familial multiple endo­ crine neoplasia type 2 syndromes (a and b). As the sensitivity of the calcitonin radioimmunoassay has improved, our understanding of the role of calcitonin in normal physiological processes has increased. The knowledge that vitamin D must be metabolized to produce its biologic effects is only 15 years old. This has had profound implications in our understanding of a variety of metabolic bone, kidney, and gastrointestinal diseases. Assays to measure the major cir­ culating form of vitamin D, 25-hydroxyvitamin D, were described 10 years ago. Assays for the other metabolites, in particular, 1,25-dihydroxyvitamin D, were described even more recently. As of today, we know of many vitamin D metabolites and have developed the techniques to measure most of them; how­ ever, many questions remain concerning their physiological role.

Biological nitrogen fixation in forest ecosystems: foundations and applications (Forestry Sciences #9)

The Comparative Economics of Plantation Forestry: A Global Assessment (Routledge Revivals)

Plantation forestry is the planting, managing, and harvesting of trees for the production of industrial wood. Originally published in 1983, the principal focus and contribution of the study lies in Roger Sedjo’s examination of the economic returns in twelve forest regions throughout the world. The results of the analysis strongly demonstrate the feasibility of major expansion of plantation forestry in a number of areas around the world and suggest the likelihood of major shifts in the principal supply areas. The results also have potentially important implications for countering the threats of deforestation. This title will be of interest for students of Environmental Studies.
