Neuware -[Hilbert's] style has not the terseness of many of our modem authors in mathematics, which is based on the assumption that printer's labor and paper are costly but the reader's effort and time are not. H. Weyl [143] The purpose of this book is to describe the classical problems in additive number theory and to introduce the circle method and the sieve method, which are the basic analytical and combinatorial tools used to attack these problems. This book is intended for students who want to lel Ill additive number theory, not for experts who already know it. For this reason, proofs include many 'unnecessary' and 'obvious' steps; this is by design. The archetypical theorem in additive number theory is due to Lagrange: Every nonnegative integer is the sum of four squares. In general, the set A of nonnegative integers is called an additive basis of order h if every nonnegative integer can be written as the sum of h not necessarily distinct elements of A. Lagrange 's theorem is the statement that the squares are a basis of order four. The set A is called a basis offinite order if A is a basis of order h for some positive integer h. Additive number theory is in large part the study of bases of finite order. The classical bases are the squares, cubes, and higher powers; the polygonal numbers; and the prime numbers. The classical questions associated with these bases are Waring's problem and the Goldbach conjecture.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 364 pp. Englisch.…

Neuware -This important book brings together a wealth of information and techniques for working with maize (corn), a plant of enormous significance as a crop and as a model system for studies in plant genetics, biochemistry, and molecular biology. This book is a bible for maize researchers, and will be of wide interest to other scientists working on other plants.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 792 pp. Englisch. …

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This edition of Thermodynamics is a thoroughly revised, streamlined, and cor rected version of the book of the same title, first published in 1975. It is intended for students, practicing engineers, and specialists in materials sciences, metallur gical engineering, chemical engineering, chemistry, electrochemistry, and related fields. The present edition contains many additional numerical examples and prob lems. Greater emphasis is put on the application of thermodynamics to chemical, materials, and metallurgical problems. The SI system has been used through out the textbook. In addition, a floppy disk for chemical equilibrium calculations is enclosed inside the back cover. It contains the data for the elements, oxides, halides, sulfides, and other inorganic compounds. The subject material presented in chapters III to XIV formed the basis of a thermodynamics course offered by one of the authors (R.G. Reddy) for the last 14 years at the University of Nevada, Reno. The subject matter in this book is based on a minimum number of laws, axioms, and postulates. This procedure avoids unnecessary repetitions, often encountered in books based on historical sequence of development in thermodynamics. For example, the Clapeyron equation, the van't Hoff equation, and the Nernst distribution law all refer to the Gibbs energy changes of relevant processes, and they need not be presented as radically different relationships.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 424 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The control of food safety in modern food processing relies upon HACCP and other systems that identify hazards and define processes to control them. These demand a thorough understanding of the properties of microbial pathogens under all the conditions that could be found in foods and the food processing environment. Detailed information about each of the main organisms responsible for causing microbial food poisoning is presented here in an accessible and systematic way. An overview of key properties for each organism is followed by a series of tables detailing the response of the organism under a range of variable conditions. This information has been prepared by the International Commission for the Microbiological Specifications of Foods (ICMSF).Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 524 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The contents of this book are intended for those concerned with the simulation of the performance of generation systems. The subject is of importance to practising electrical engineers because of the many situations that arise in the design and operation of modem electromechanical systems and electrical power systems. The simulation programs contained in this book cover the prediction of generator performance for both large and small scale units. Synchronous generators of the round rotor and salient-pole variety of ratings of between a few Megawatts to around 1200 MW are invariably used by public supply companies for the generation of electrical power. For industrial purposes a variety of types of generator are used, including steam and gas turbines, and medium to low speed diesel engine driven generators, the former for those cases where process steam is available and the latter often in the role of marine generation or in a standby role.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 120 pp. Englisch.…
