This item is printed on demand - it takes 3-4 days longer - Neuware -As an introduction to the present book I would like to explain how it was, that I, a commercial nurseryman, became so keenly interested in Conifers and their nomen clature. In August 1924 the Dutch Dendrological Society was founded and at the same time a Committee for Nomenclature of woody plants was set up and I served on this committee as one of the members. Our first activity was to bring the catalogues of the various leading nurserymen in the Netherlands into line with the International Rules of Botanical Nomenclature and also to check their nursery stock. Formerly these catalogues had shown a rather confused nomenclature, nurserymen having usually made use of a variety of inconsistent books as guides in compiling their catalogues. In the course of the work a close co-operation between scientific and practical workers developed. Although I had also fully contributed to the correct naming of hardy shrubs and perennials, 1 was most interested in Conifers. I had tried out several species, had grown a wide choice of garden forms and selected types of particular merit for propagation. My special love for Conifers lead to the publication of my Name-list of Conifers (1937), which was adopted as a standard for varietal names at the International Horticultural Congress in Berlin (1938). Later I prepared my book 'Coniferen, Ephedra en Ginkgo' in the Dutch language (1949); compiling the Conifers cultivated or known to be grown in the Netherlands and Belgium at that time. 536 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The student of biological science in his final years as an undergraduate and his first years as a graduate is expected to gain some familiarity with current research at the frontiers of his discipline. New research work is published in a perplexing diversity of publications and is inevitably concerned with the minutiae of the subject. The sheer number of research journals and papers also causes confusion and difficulties of assimilation. Review articles usually presuppose a background knowledge of the field and are inevitably rather restricted in scope. There is thus a need for short but authoritative introductions to those areas of modern biological research which are either not dealt with in standard introductory textbooks or are not dealt with in sufficient detail to enable the student to go on from them to read scholarly reviews with profit. This series of books is designed to satisfy this need. The authors have been asked to produce a brief outline of their subject assuming that their readers will have read and remembered much of a standard introductory textbook of biology. This outline then sets out to provide by building on this basis, the conceptual framework within which modern research work is progressing and aims to give the reader an indication of the problems, both conceptual and practical, which must be overcome if progress is to be maintained. 84 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book attempts to summarize what we know about inseet-plant relationships without beeoming too involved with untestable hypo theses. It is not intended to be eomprehensive and we have deliberately excluded diseussion of aquatie organisms and fungi. Our definition of inseet herbivores is intentionally broad. It includes all inseets whieh feed on plants, although we have emphasized those whieh feed primarily on the photosynthetie tissues. Some referenee is made to seed predation but pollination eeology is excluded. We thank Ors P.H. Smith and M. Luxton for their helpful eommenb on the manuseript but we accept full responsibility for any mistakes whieh may remain. Finally, we thank the various publishers and a uthor~ who gave us permission to use copyright material. 7 I Introduction The net primary produetion of the 300000 speeies of vaseular plant whieh inhabit the dry land surfaee of the earth has been estimated at 9 about 115 x 10 t per annum. This represents a massive resouree potentially available for exploitation by the herbivorous inseets, which themselves probably number in exeess of 500000 species. 80 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The first Joint Meeting of the Austrian and Swiss Operations Research Societies was held at the University of Technology in Vienna, Austria, from 22-24 September 1980. A selection of the papers then presented are published in this volume. The papers included provide a picture of Operations Research as a discipline comprehending various methods and models. The volume is divided into two parts. The first part contains papers on mathematical programming and optimal control theory. Moreover, two papers on decision and game theory are included as well as two on biomathematical to~ics. Being more heterogeneous, the second part, on stochastic models, includes such topics as queueing theory, econometrics and time series analysis. As a special feature of the symposium, a series of applications of OR models in energy planning were discussed, e.g., load and demand forecasting, power distribution and extension planning, reliability and work-safety, etc. These papers have been incorporated into parts one and two according to the models used.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Fifteenth Jerusalem Symposium reflected the high standards of the former international scientific meetings, which convene once a year at the Israel Academy of Sciences and Humanities in Jerusalem to discuss a specific topic in the broad area of quantum chemistry and biochemistry. The topic at this year's Jerusalem Symposium was intramo lecular dynamics, a subject of central interest for theoreticians, che mists and biologists. During the last two decades, there has been remarkable pro gress in our understanding of time dependent phenomena. The development and application of the modern techniques of quantum mechanics and sta tistical mechanics to excited-state dynamics and to chemical and biophy sical systems constitutes a fast developing current research area. The main theme of the Symposium was built around a conceptual framework for the elucidation of photophysical and photochemical phenomena in atoms, molecules, van der Waals complexes and clusters, condensed phases, poly mers and biological supermolecules. The interdisciplinary nature of this research field was deliberated by intensive and extensive interactions between scientists from different disciplines and between theory and experiment. This volume provides a record of the invited lectures at the Symposium. 574 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -the Logische Untersuchungen,l phenomenology has been conceived as a substratum of empirical psychology, as a sphere comprising 'imma nental' descriptions of psychical mental processes, a sphere compris ing descriptions that - so the immanence in question is understood - are strictly confined within the bounds of internal experience. It 2 would seem that my protest against this conception has been oflittle avail; and the added explanations, which sharply pinpointed at least some chief points of difference, either have not been understood or have been heedlessly pushed aside. Thus the replies directed against my criticism of psychological method are also quite negative because they miss the straightforward sense of my presentation. My criticism of psychological method did not at all deny the value of modern psychology, did not at all disparage the experimental work done by eminent men. Rather it laid bare certain, in the literal sense, radical defects of method upon the removal of which, in my opinion, must depend an elevation of psychology to a higher scientific level and an extraordinary amplification ofits field of work. Later an occasion will be found to say a few words about the unnecessary defences of psychology against my supposed 'attacks. 426 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is devoted to stochastic and chaotic oscillations in dissipative systems. Chapter 1 deals with mathematical models of deterministic, discrete and distributed dynamical systems. In Chapter 2, the two basic trends of order and chaos are considered. The next three chapters describe stochasticity transformers, amplifiers and generators, turbulence, and phase portraits of steady-state motions and their bifurcations. Chapter 6 treats the topics of stochastic and chaotic attractors, and this is followed by two chapters dealing with routes to chaos and the quantitative characteristics of stochastic and chaotic motions. Finally, Chapter 9, which comprises more than one-third of the book, presents examples of systems having chaotic and stochastic motions drawn from mechanical, physical, chemical and biological systems. The book concludes with a comprehensive bibliography. For mathematicians, physicists, chemists and biologists interested in stochastic and chaotic oscillations in dynamical systems. 498 pp. Englisch.…
