Energie und Umwelt als Optimierungsaufgabe: Das MARNES-Modell

by Manfred Walbeck Hermann-Josef Wagner Dag Martinsen Vinzenz Bundschuh

Optimierungsmodelle werden immer häufiger zur Beschreibung des Verhaltens komplexer Systeme herangezogen. Dieses Buch beschäftigt sich mit den Möglichkeiten und Grenzen des Einsatzes umfangreicher Optimierungsmodelle zur Beantwortung umweltrelevanter Probleme der Energieversorgung. Am Beispiel des in der Systemanalyseforschung in Jülich entwickelten MARNES-Modells wird fast lehrbuchhaft der Weg von der vorgegebenen Fragestellung über die Modellierung selbst bis hin zur Anwendung aufgezeigt. Breiten Raum nehmen die Ausführungen zum Linearen Programmieren und zur datenmäßigen Charakterisierung der Technologien ein. Mit diesem Buch liegt erstmals eine detaillierte Beschreibung eines Energie- und Umweltmodells vor. Das Buch wendet sich an Wissenschaftler in der Systemanalyse und im Operations Research genauso wie an die Praktiker in den Planungsabteilungen der Energiewirtschaft und in den verschiedenen öffentlichen Institutionen.

Environmental Management of Solid Waste: Dredged Material and Mine Tailings

by Wim Salomons and Ulrich Förstner

Dredged Material and Mine Tailings are two of the same thing once they are deposited on land: they must be safe-guarded, wash-out must be prevented, and they must be protected by a plantcover. This comprehensive two-volume treatise covers both important aspects of their management: Environmental Management of Solid Waste turns to the practical applications, such as prediction, restoration and management, while in Chemistry and Biology of Solid Waste the principles and assessment are scientifically studied and discussed. Previously, dredged material was a commodity, it could be sold as soil, e. g. to gardeners. In the meantime, dredged material from the North Sea (e.g. the Rotterdam or Amsterdam harbor) must be treated as hazardous waste. Many environmentalists, managers and companies do not know how to solve the inherent problems. This new work deals with the chemical, physical and biological principles; the biological and geochemical assessment; the prediction of effects and treatment; and finally, with restoration and revegetation. It is written by many leading scientists in the various fields, and will prove invaluable for managers and politicians who are concerned with the present environmental situation.

Genetic Manipulation of Woody Plants (Basic Life Sciences #44)

by James W. Hanover Daniel E. Keathley

This Volume contains the papers presented by twenty-eight invited speakers at the symposium entitled, "Genetic Manipulation of Woody Plants," held at Michigan State University, East Lansing, Michigan, from June 21-25, 1987. Also included are abstracts of contributed poster papers presented during the meeting. That the molecular biology of woody plants is a rapidly expanding field is attested to by the large attendance and high level of enthusiasm generated at the conference. Leading scientists from throughout the world discussed challenging problems and presented new insights into the devel­ opment of in vitro culture systems, techniques for DNA analysis and manipulation, gene vector systems, and experimental systems that will lead to a clearer understanding of gene expression and regulation for woody plant species. The presence at the conference of both invited speakers and other scientists who work with nonwoody plant species also added depth to the discussions and applicability of the information presented at the conference. The editors want to commend the speakers for their well-organized and informative talks, and feel particularly indebted to the late Dr. Alexander Hollaender and others on the planning committee who assist­ ed in the selection of the invited speakers. The committee consisted of David Burger (University of California, Davis), Don J. Durzan (University of California, Davis) , Bruce Haissig (U. S. Department of Agriculture Forest Service), Stanley Krugman (U. S. Department of Agriculture Forest Service) , Ralph Mott (North Carolina State University), Otto Schwarz (Univer.sity of Tennessee, Knoxville), and Roger Timmis (Weyerhaeuser Company).

Iron in Soils and Clay Minerals (Nato Science Series C: #217)

by J.W. Stucki B.A. Goodman U. Schwertmann

Probably more than any other element, iron markedly influences the chemical and physical properties of soils and sediments in the earth. Considering its transition metal status, with potential variation in electronic configuration, ionic radius, and magnetic moment, combined with its abundance and relatively large mass, little wonder that one sees its unique influence on every hand. Pre­ sentations at the NATO Advanced Study Institute (NATO AS!) on Iron in Soils and Clay Minerals reviewed and discussed the occurrence, behavior, and properties of Fe-bearing minerals found in soils and in the clay mineral groups kaolinite, smectite, and mica. Also discussed at the NATO AS! were the basic chemical properties of Fe, methods for separating and identifying Fe in minerals, and the role of Fe minerals in weathering and other soil-forming processes. The present publication is the reviewed and edited proceedings of that Advanced Study Institute. The sequence of chapters follows the general pattern beginning with introductory chapters which overview the general occurrence of Fe in the earth and its chemistry, both generally and in mineral environments, followed by identification and characterization methods for Fe and Fe phases in minerals. The properties and behavior of Fe oxides, Fe-bearing clay minerals, and other Fe minerals in soils are then described, and the text ends with a summary of the role of Fe in soil-forming processes. A Table of Contents and subject index are provided to assist the reader in finding specific topics within the text.

Manganese in Soils and Plants: Proceedings of the International Symposium on ‘Manganese in Soils and Plants’ held at the Waite Agricultural Research Institute, The University of Adelaide, Glen Osmond, South Australia, August 22–26, 1988 as an Australian Bicentennial Event (Developments in Plant and Soil Sciences #33)

by R. D. Graham R. J. Hannam N. C. Uren

Sixty years ago at the Waite Agricultural Research Institute, G. Samuel, a plant pathologist, and C. S. Piper, a chemist, published their conclusion that the cause of roadside take-all, a disease of oats, was manganese deficiency. This report, together with the concurrent and independent studies of W. M. Carne in Western Australia were the first records of manganese deficiency in Australia and came only six years after McHargue's paper which is generally accepted as the final proof of the essentiality of this element. There must have been a few doubts for some people at the time, however, as the CAB publication, 'The Minor Elements of the Soil' (1940) expressed the view that further evidence to this effect was provided by Samuel and Piper. Their historic contributions are recognised by the International Symposium on Manganese in Soils and Plants as it meets on the site of their early labours to celebrate the 60th anniversary. This year Australians also acknowledge 200 years of European settlement in this country and so the Symposium is both a Bicentennial and a diamond jubilee event which recognises the impact of trace elements on agricultural development in Australia. In a broader sense, a symposium such as this celebrates, as it reviews, the efforts of all who over the ages have contributed to our knowledge of manganese in soils and plants.

The Mathematics of Blunt Body Sampling (Lecture Notes in Engineering #38)

by Sarah J. Dunnett Derek B. Ingham

Particle samplers are widely used in workplaces in order to determine the concentration of airborne particles in the atmosphere. They generally operate by drawing air, with the aid of a pump, through one or more orifices in the sampler body and housed within the sampler is a filter through which the air is subsequently drawn. The airborne particles are collected on the filter and their concentration is determined. Various samplers have been designed for this purpose including "static" samplers, which are located in a fixed position in a working environment and determine the dust concentration averaged over a prescribed period of time at that one point, and "personal" samplers which are mounted on a working person near to the breathing zone. The ORB sampler, a static sampler designed by Ogden and Birkett (1978) to have approximately the same entry efficiency, for particles with aerodynamical diameter up to at least 25~m, as a human head equally exposed to all wind directions for wind speeds between 0 and 2. 75m1s, is shown in Fig. l. l and examples of personal samplers are shown in Fig. 1. 2a, b and c and represent a single 4mm hole sampler, a seven hole sampler and a 25mm open face filter holder respectively. These three samplers are some of the most commonly used personal samplers for sampling the total airborne concentrations of workplace dusts in Britain.

Mississippi Solo: John Murray Journeys (Overcoming Books)

by Eddy L Harris

INTRODUCED BY ADAM WEYMOUTH, award-winning author of The Kings of Yukon'A wonderful book -- and a highly original contribution to the literature of travel' PAUL THEROUX'The Mississippi. Mighty, muddy, dangerous, rebellious and yet a strong, fathering kind of river. The river captured my imagination when I was young and has never let go.' Mississippi Solo tells the story of one man's voyage by canoe down the Mississippi River from its source in Minnesota to the Gulf of Mexico - a longtime dream, and a journey of over 2,000 miles through the heart of America. Paddling into the Southern states - going from 'where there ain't no black folks to where they still don't like us much' - Eddy is confronted by the legacy of slavery and modern racism, including an incident with a pair of shotgun-toting bigots. There are also the dangers of passing barges, wild dogs roaming the wooded shore, and navigating a waterway that grows vaster, and more hazardous, every day. But Eddy also encounters immense human kindness, friendship and hospitality, as well as coming to know the majestic power - and the awesome dangers - of the river itself. Mississippi Solo is an unforgettable American adventure.
