Assessment Methods for Soil Carbon (Hardcover): John M. Kimble, Ronald F. Follett, B.A. Stewart Assessment Methods for Soil Carbon (Hardcover)
John M. Kimble, Ronald F. Follett, B.A. Stewart
R3,892 Discovery Miles 38 920 Ships in 12 - 17 working days

Since carbon sequestration in soils reduces the amount of carbon available to the atmosphere, the Kyoto Protocols have heightened interest in soil carbon pools and their effect on carbon fluxes. Assessment Methods for Soil Carbon addresses many of the questions related to the measurement, monitoring, and verification of organic and inorganic carbon in soils. The major topics covered are: carbon pools; soil sampling
and preparation, analytical techniques for soil carbon; soil erosion and sedimentation; remote sensing, GIS and modeling; procedures for scaling carbon data from point and local measurements to regional and even national scales; and economic and policy issues.

In Assessment Methods for Soil Carbon, leading researchers show that we now have the ability to measure, monitor, and verify changes to soil carbon. The book establishes the need for standardized methods that can be used by anyone, and helps us better understand the link between the pedosphere (soils) and the atmosphere. It also shows the importance of developing links between the economics of carbon sequestration and the amounts sequestered, and highlights the need for scientists and policy makers to interact to ensure that policies fit within the scope of present technologies.

Colour and the Optical Properties of Materials (Hardcover, 3rd Edition): Richard J. D. Tilley Colour and the Optical Properties of Materials (Hardcover, 3rd Edition)

R2,117 Discovery Miles 21 170 Ships in 12 - 17 working days

The updated third edition of the only textbook on colour The revised third edition of Colour and the Optical Properties of Materials focuses on the ways that colour is produced, both in the natural world and in a wide range of applications. The expert author offers an introduction to the science underlying colour and optics and explores many of the most recent applications. The text is divided into three main sections: behaviour of light in homogeneous media, which can largely be explained by classical wave optics; the way in which light interacts with atoms or molecules, which must be explained mainly in terms of photons; and the interaction of light with insulators, semiconductors and metals, in which the band structure notions are of primary concern. The updated third edition retains the proven concepts outlined in the previous editions and contains information on the significant developments in the field with many figures redrawn and new material added. The text contains new or extended sections on photonic crystals, holograms, flat lenses, super-resolution optical microscopy and modern display technologies. This important book: Offers and introduction to the science that underlies the everyday concept of colour Reviews the cross disciplinary subjects of physics, chemistry, biology and materials science, to link light, colour and perception Includes information on many modern applications, such as the numerous different colour displays now available, optical amplifiers lasers, super-resolution optical microscopy and lighting including LEDs and OLEDs Contains new sections on photonic crystals, holograms, flat lenses, super-resolution optical microscopy and display technologies Presents many worked examples, with problems and exercises at the end of each chapter Written for students in materials science, physics, chemistry and the biological sciences, the third edition of Colour and The Optical Properties of Materials covers the basic science of the topic and has been thoroughly updated to include recent advances in the field.

Four Centuries of Clinical Chemistry (Hardcover): Louis Rosenfeld Four Centuries of Clinical Chemistry (Hardcover)
Louis Rosenfeld
R4,613 Discovery Miles 46 130 Ships in 12 - 17 working days

The origin and early years of any rapidly changing scientific discipline runs the risk of being forgotten unless a record of its past is preserved. In this, the first book-length history of clinical chemistry, those involved or interested in the field will read about who and what went before them and how the profession came to its present state of clinical importance. The narrative reconstructs the origins of clinical chemistry in the seventeenth century and traces its often obscure path of development in the shadow of organic chemistry, physiology and biochemistry until it assumes its own identity at the beginning of the twentieth century. The chronological development of the story reveals the varied roots from which modern clinical chemistry arose.

Atoms and Elements - A Study of Theories of Matter in England in the Nineteenth Century (Paperback): David M Knight Atoms and Elements - A Study of Theories of Matter in England in the Nineteenth Century (Paperback)
David M Knight
R792 Discovery Miles 7 920 Ships in 12 - 17 working days

First published in 1967. The impression is sometimes given that the Atomic Theory was revived in the early years of the nineteenth century by John Dalton, and that continuously from then on it has played a vital role in chemistry. The aim of this study is to revise this over-simplified picture. Atomic explanations seemed to chemists to go beyond the facts, to fail to lend themselves to mathematical expression, and to deny the ultimate simplicity and unity of all matter. Most, therefore, rejected them. Meanwhile, physicists were developing a whole range of atomic theories to explain the physical properties of bodies in terms of very simple atoms or particles. During the last thirty years of the century the position changed, as physicists and chemists came to agree on a common atomic theory. But the last prominent opponents of atomism were not converted until the early years of the twentieth century, by which time studies of radioactivity had made it clear that the billiard-ball Daltonian atom must, in any case, be abandoned.

Bald leben mehr als eine Million (!) Waschbaren in unseren Waldern und nicht nur da sie kommen uns auch in den Stadten "besuchen". Die putzigen Kerlchen konnen nichts dafur, denn wir sind an ihrer Verbreitung Schuld, da wir das okologische Gleichgewicht der Natur gestort haben. Doch was genau ist eigentlich Okologie jenseits von Okostrom und Okolabel? Hightech-Ameisen, hochintelligente Krahen und der Urzeit-Ginkgo Alles hangt mit allem zusammen: Gerat ein okologisches Teilsystem aus dem Gleichgewicht, lost das oft eine Kettenreaktion aus. In dem Teil Zusammen leben fragt Michael Gross u. a., ob Schutzgebiete wirklich die bedrohten Arten schutzen, erzahlt uber die Wanderschaft von Pflanzenschadlingen, die sich durch weltweite Handelsnetze auch global verbreiten, oder stellt einen Uberlebenden der Dinosaurierzeit vor: den Ginkgo. Warum uberlebte er damals das Massensterben der Arten? Kohlendioxidschwaden, Vibrationen, Magnetismus, Pedometer und noch vieles mehr: All das besitzt z. B. ein sehr kleines Lebewesen die Ameise. Sie findet mit dieser "Ausstattung" sogar in der Wuste wieder zu ihrem Nest zuruck. Im Teil Aktiv leben stellt uns Gross diese kleinen tierischen Wunderwerke vor, berichtet aber auch von den hochintelligenten Krahen oder erzahlt, wie das Krokodil seine Zahne bekam. Im Abschnitt Weiter leben gibt er einen Ausblick auf die unmittelbare Zukunft des Lebens auf der Erde, die immer starker von menschlichen Aktivitaten gepragt wird: das Zeitalter des "Anthropozan" ist angebrochen!
