Volume 2 covers nitrogen fertilizer efficiency, acid tolerance of the legume symbiosis, fruit tree nutrition, rhizosphere pH change, iron deficiency in crop production, the effects of nutrient deficiences on seed production, the elemental composition of plants, and the role of potassium. The articles in this volume join together both the fundamental and the applied parts of this discipline. The editors' aim to make the reviews comprehensible to scientists in relevant disciplines, rather than purely to the specialist. The format of each volume is a small number of full-length reviews of important topics, plus an editorial which briefly mentions other rapidly developing topics that may therefore be reviewed in future volumes.

Advances In Plant Nutrition, Volume Three, is the latest edition to Tinker's and Lauchli's series on major research efforts in plant nutrition. It synthesizes both basic and applied information in such areas as soil-plant relations, nutritional physiology, and plant nutrition technology. This combination of both fundamental and applied topics is a thorough and substantial coverage of plant nutrition, and will supplement the first two volumes. Researchers in agriculture, plant physiology, botany, forestry, and soil science will find this an invaluable resource, as will industrial and commercial producers of fertilizers who wish to be up to date on relevant topics. This comprehensive work contains six papers by experts in the field. The first essay discusses the difficult area of measuring intercell material flow via membranes, while the second explains chlorine as both a plant nutrient and osmotic balancing ion. The role of root exudates in nutrient acquistion is the topic of the third paper; plant nutrition in flood soil is the basis for the fourth. The next essay addresses how plants adopt different growth strategies in the often nutrient-poor natural environment. Finally, the background of leaf analysis systems is explored.

Ernst Specker has made decisive contributions towards shaping direc tions in topology, algebra, mathematical logic, combinatorics and algorith mic over the last 40 years. We have derived great pleasure from marking his seventieth birthday by editing the majority of his scientific publications, and thus making his work available in a unified form to the mathematical community. In order to convey an idea of the richness of his personality, we have also included one of his sermons. Of course, the publication of these Selecta can pay tribute only to the writings of Ernst Specker. It cannot adequately express his originality and wisdom as a person nor the fascination he exercises over his students, colleagues and friends. We can do no better than to quote from Hao Wang in the 'Festschrift' Logic and Algorithmic I: Specker was ill for an extended period before completing his formal education. He had the leisure to think over many things. This experi ence may have helped cultivating his superiority as a person. In terms of traditional Chinese categories, I would say there is a taoist trait in him in the sense of being more detached, less competitive, and more under standing. I believe he has a better sense of what is important in life and arranges his life better than most logicians. We are grateful to Birkhauser Verlag for the production of this Selecta volume. Our special thanks go to Jonas Meon for sharing with us his intimate knowledge of his friend Ernst Specker."

Salinity: Environment - Plants - Molecules (Hardcover, 2002 ed.): Andre Lauchli, Ulrich L Uttge Salinity: Environment - Plants - Molecules (Hardcover, 2002 ed.)
Andre Lauchli, Ulrich L Uttge
R5,841 Discovery Miles 58 410 Ships in 10 - 15 working days

This book addresses the responses of plants to salinity. Although salinity is a common environmental factor for marine organisms, for the majority of land plants high soil salinity is an environmental constraint that limits growth, productivity, and normal plant functions. Salinity is particularly widespread in arid/semiarid climates where crop production depends on irrigation.

A comprehensive approach is taken in this book. After discussing salinity as an environmental soil factor and its global impact on ecosystems, plant responses are covered from the whole-plant level through metabolic changes to the underlying molecular and genetic mechanisms. In contrast to other books in this subject area, which focus on certain aspects of plant responses to salinity or are conference proceedings, this is the only comprehensive new book on this subject, written by experts in the field. The intended level of readership is graduate students and advanced researchers interested in environmental biology and specifically in the area of mechanisms of environment-plant interactions.

R3,000 Discovery Miles 30 000 Ships in 10 - 15 working days

The first book bearing the title of this volume, Inorganic Plant Nutrition, was written by D. R. HOAGLAND of the University of California at Berkeley. As indicated by its extended title, Lectures on the Inorganic Nutrition of Plants, it is a collection of lectures - the JOHN M. PRATHER lectures, which he was invited in 1942 to give. at Harvard University and presented there between April 10 and 23 of that year - 41 years before the publication of the present volume. They were not "originally intended for publication" but fortunately HOAGLAND was persuaded to publish them; the book appeared in 1944. It might at first blush seem inappropriate to draw comparisons between a book embodying a set of lectures by a single author and an encyclopedic volume with no less than 37 contributors. But HOAGLAND'S book was a compre hensive account of the state of this science in his time, as the present volume is for ours. It was then still possible for one person, at least for a person of HOAGLAND'S intellectual breadth and catholicity of interests, to encompass many major areas of the entire field, from the soil substrate to the metabolic roles of nitrogen, potassium, and other nutrients, and from basic scientific topics to the application of plant nutritional research in solving problems encountered in the field."

Dieses Lehrbuch nimmt Sie mit auf eine Entdeckungsreise durch die Welt der klassischen Geometrie: Beginnend beim Satz von Thales und den Apolloniuskreisen fuhrt die Reise uber Steiner'sche Kreisketten bis in die Welt der Kegelschnitte. Dabei werden verborgene Zusammenhange aufgedeckt und Perlen der Elementargeometrie prasentiert. Hierbei werden Sie durch harmonische Verhaltnisse geleitet, welche eine zentrale Rolle spielen und sich wie ein roter Faden durch das ganze Buch ziehen. Einerseits ist dieses Buch fur alle Liebhaberinnen und Liebhaber der Geometrie geschrieben, andererseits ist es durch die leicht zugangliche Theorie und die kurzen Beweise besonders auch fur Schulerinnen und Schuler der Sekundarstufe sowie Lehramtsstudierende geeignet. Die zweite Auflage des Buches enthalt neu Loesungen und Hinweise zu allen Aufgaben. Zusatzlich wurde ein Abschnitt uber die Zyklographie eingefugt. Diese heute fast in Vergessenheit geratene Abbildung erlaubt eine verbluffend einfache und elementare Loesung des Apollonischen Beruhrungsproblems. Die ebenfalls neuen Abschnitte uber trilineare Koordinaten und das Ceva- und das Anti-Ceva-Dreieck ermoeglichen einen Ausblick in die moderne Dreiecksgeometrie.

Algorithmische Graphentheorie (German, Paperback, 1991 ed.): Lauchli Algorithmische Graphentheorie (German, Paperback, 1991 ed.)

R1,865 Discovery Miles 18 650 Ships in 10 - 15 working days

Graphentheorie: eine Theorie, oder einfach eine Methode, um Sachverhalte an- schaulich darzustellen, die auch in anderer Weise erfassbar waren? Beides trifft zu: Tatsachlich ist die Graphentheorie heute bereits ein recht weit entwickelter Zweig der diskreten Mathematik, mit dem sich Spezialisten befassen. Auf der anderen Seite bietet die Abstraktion von Problemstellungen aus der "rea- len" Welt auf die beiden urspriinglich der Geometrie entliehenen Elemente "Punkt" und "Kante" eine reizvolle Gelegenheit, auch fUr die Losung von Aufgaben eher kombinatorischer Natur an die bildliche Vorstellung zu appellieren. Dieses Buch ist aus dem Manuskript einer einsemestrigen Vorlesung entstan- den, die ich mehrere Male an der Eidgenossischen Technischen Hochschule Ziirich (ETH) fUr Studenten der Informatik und der Mathematik in mittleren Semestern gehalten habe. Der Text richtet sich - ausser an dies en Kreis - durchaus auch an Studenten von Hoheren Technischen Lehranstalten (bzw. Fachhochschulen), sowie an Gymnasiallehrer. Die letzteren werden zwar den Stoff kaum als geschlos- senen Lehrgang beniitzen, konnen jedoch eventuell einzelne herausgegriffene Teile im Unterricht der oberen Klassen einbringen. Das Buch solI zunachst eine erste EinfUhrung in die Graphentheorie vermitteln - wer nur diese sucht, kann im Extremfall die Kapitel 3 und 4, sowie in den folgenden Kapiteln alles, was sich auf Algorithmen bezieht, weglassen.

Der Inhalt dieses Buches entspricht weitgehend dem Stoff, den die beiden Autoren seit mehreren Jahren in einem zweisemestrigen Kurs fur Informatiker an der ETH Zurich vermitteln. Vieles davon ist bereits fruher in der Form von provisorischen Notizen von E. Engeler als "Kleines Repetitorium der Berechnungstheorie" an die Stu denten abgegeben worden. Bei der Niederschrift des nun vorliegenden Textes hat sich immer deutlicher gezeigt, dass sich eine weitgehend unabhangige Redaktion der beiden, jetzt auch im Inhaltsverzeichnis abgegrenzten Teile, sowohl arbeitstechnisch als auch von der Stoffbehandlung her, als durchaus naturlich aufdrangte. So hat denn P. Lauchli den ersten, E. Engeier den zweiten Teil selbstandig betreut. Wir haben uns zwar punkto Notation weitgehend abgesprochen, nehmen jedoch eine gewisse Verschiedenheit im Stil bewusst in Kauf. Fur die Lekture des Buches wird vorausgesetzt, dass der Leser uber das mathema tische Rustzeug verfugt, welches etwa in einem elementaren Kurs "Diskrete Mathema tik" in den unteren Semestern eines Hochschulstudiums, Richtung Informatik oder Elek trotechnik, angeboten wird. Dazu gehoren jedenfalls Grundbegriffe bezuglich Mengen, Funktionen, Relationen etc. Der erste Teil, im allgemeinen elementarer formuliert, entspricht ungefahr der oben erwahnten ersten Vorlesung ("Berechnungstheorie," 4. Semester), in welcher vor allem der Berechenbarkeitsbegriff herausgearbeitet und eine erste Bekanntschaft mit der Erzeu gung, bzw. Erkennung von formalen Sprachen anhand der ausfuhrlich diskutierten regularen Sprachen vermittelt wird. Die anschliessend eingefuhrte Fixpunkttheorie soll dem Studenten ein theoretisches Werkzeug in die Hand geben, welches ihm erlaubt, ver schiedene Gegenstande von einem einheitlichen Standpunkt aus zu betrachten."

Grosse Rechenzentren bieten Computerleistung uber Telefonnetz und Terminal. Hersteller bieten ,,Mini" -Computersysteme , die eben soviel leisten, wie vor wenigen Jahren grosse Rechenanlagen. Be triebssysteme sind vielseitiger und gleichzeitig einfacher in der Be dienung geworden. Problemorientierte Programmiersprachen und ganze Programmpakete erleichtern die Loesung fachbezogener Pro bleme in zahlreichen Gebieten. Dies alles hat dazu gefiihrt, dass die Benutzung von Computerleistung nicht mehr einigen Computerspe zialisten vorbehalten bleibt. Vielen Ingenieuren ist heute der Com puter als Hilfsmittel zur Erfullung ihrer Aufgaben ein ebenso alltag liches Werkzeug geworden, wie es fruher der Rechenschieber war. Manchem Ingenieur oder Naturwissenschaftler fehlen jedoch die notwendigen Kenntnisse und Erfahrungen fur eine computerge rechte Loesung seiner Probleme. Der Besuch eines FORTRAN-Kur ses allein bietet hierzu keine genugende Grundlage mehr. Seit 1974 bietet deshalb das Schweizer Kapitel der Association for Computing Machinery (ACM) mit einer Reihe von Kursen und Seminaren den in der Industrie tatigen Ingenieuren die Moeglichkeit, ihre Kenntnisse in Informatik zu erweitern. Das vorliegende Werk ist aus dieser Reihe entstanden. Es wendet sich gleichermassen an Studenten von Hochschulen und Ingenieurschulen und an praktizie rende Ingenieure. Es setzt eine gewisse Programmiererfahrung vor aus: die Autoren erwarten vom Leser die Kenntnis einer Program miersprache. Das Buch ist keine Enzyklopadie, eine umfassende Behandlung des Fachgebietes Informatik ist in diesem Rahmen nicht moeglich. Die Autoren haben sich zum Ziel gesetzt, dem Leser eine Auswahl von - nach ihrem Ermessen - fur den angesprochenen Leserkreis wichtigen Themen zu bieten. Ich danke den Autoren fur die ausgezeichnete Zusammenarbeit.
