Biochemical consequences of the interaction of amastigotes with Pentostam are inhibition of parasite bioenergetics and inhibition of ATP synthesis. REFERENCES 1. J.C. Mottram and G.H. Coombs.

The infrared spectra of the main classes of cellulose derivatives are de scribed and interpreted and those of such model compounds as mono-, di-, and trisaccharides are considered. Considerable attention is given to prob lems of technique in obtaining infrared spectra of fibrous cellulose materials, and to the analytical possibilities of infrared spectroscopy in studies of the properties of cellulose and its derivatives. The book will be of use to scientific and plant workers interested in the study and treatment of cellulose, compounds related to cellulose (carbo hydrates and polycarbohydrates), and other polymers. v INTRODUCTION Spectroscopy has nowadays acquired great scientific and practical im portance. Its possibilities are based on the specificity of the emission and ab sorption spectra of all types of material, from elements to complex natural products. Most widely used are the methods of emission spectral analysis (analysis of the emission spectrum from an incandescent body). The rapidity and availability of these methods, together with their high sensitivity and selectivity, has made them indispensable in the practice of plant and scien tific laboratories for establishing the presence of specific elements in a sub stance under investigation. 348 pp. Englisch.

All the topics treated hefe are eluci dated in terms of concrete examples, which have been chosen, for the most part, from the Held of analysis of the mechanical properties of steel, wood, and other materials. A necessary prerequisite for any study of correlation equations is so me knowledge of the moments of random variables. In the Appendix, there is provided a brief treatment of moments, as well as a discussion of the simplest methods of computing them. We have paid particular attention in this book to the techniques of computing correlation equations, and to the use of tables for alleviating the computationalload. The mathematical bases of the methods used in setting up correlation equations are expounded in the books cited at the end of this volume. A. M.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is prepared from lecture notes for the course 'Intercalation in Layered Materials' which was held at the Ettore Majorana Centre for Scientific Culture at Erice, Sicily in July, 1986, as part of the International School of Materials Science and Tech nology. The course itself consisted of formal tutorial lectures, workshops, and informal discussions. Lecture notes were prepared for the formal lectures, and short summaries of many of the workshop presentations were prepared. This volume is based on these lecture notes and research summaries. The material is addressed to advanced graduate students and postdoctoral researchers and assumes a background in basic solid state physics. The goals of this volume on Intercalation in Layered Materials include an introduc tion to the field for potential new participants, an in-depth and broad exposure for stu dents and young investigators already working in the field, a basis for cross-fertilization between workers on various layered host materials and with various intercalants, and an elaboration of the complementarity of intercalated layered materials with deliberately structured superlattices. 512 pp. Englisch.

The sources of the volumes are as follows: for Vol. I, the 1st All-Union Conference on Crystal Growth; for Vol. 3, the 2nd; and for Vols. 5 and 6, the 3rd; Vols. 7 and 8 reported the International Symposium on Crystal Growth at the Seventh International Crystallography Con gress, and Vol. 9 the 1969 symposium on crystal growth dedicated to E. S. Fedorov; Vols. 2, 4, and 10 did not originate in conferences. The main problem that largely occupied the conferences and symposia and also the inter mediate volumes was that of real crystal formation, as well as the relation of crystal growth theory to practical crystal production. This tenth volume, which completes this first series, is to a considerable extent a survey. It contains more extensive theoretical and experimental original papers, as well as some shorter papers dealing with particular but important aspects of real crystal formation. The volume opens with a paper by V. V. Voronkov, which deals with the structure of crystal surface in Kossel's model. The model as proposed by Kossel is extremely simple. It deals qualitatively with the basic trends in the growth of an idealized crystal in its own va por at absolute zero, and naturally does not allow one to perform quantitative studies on com plex real processes.' 168 pp. Englisch.

The meeting was held in Chicago, Illinois U.S.A. on August 30 - September 1, 1976. Since 1967 this series of conferences has served as an international forum for bringing together the many different facets of the ultrasonic visualization field. Medical diagnosis, nondestructive testing, underwater viewing, seismic the mapping, and acoustic analytical microscopy are examples of broad range applications of this technology. Throughly broad in scope, the common denominator that binds this volume together is the application of engineering and physics disciplines to the creation of images by means of ultrasonic waves.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book introduces two most important aspects of modern analysis: the theory of measure and integration and the theory of Banach and Hilbert spaces. It is designed to serve as a text for first-year graduate students who are already familiar with some analysis as given in a book similar to Apostol's Mathematical Analysis. t This book treats in sufficient detail most relevant topics in the area of real and functional analysis that can be included in a book of this nature and size and at the level indicated above. It can serve as a text for a solid one-year course entitled 'Measure and Integration Theory' or a com prehensive one-year course entitled 'Banach Spaces, Hilbert Spaces, and Spectral Theory. ' For the latter alternative, the student is, of course, required to have some knowledge of measure and integration theory. The breadth of the book gives the instructor enough flexibility to choose what is best suited for his/her class. Specifically the following alternatives are available: (a) A one-year course on 'Measure and Integration' utilizing Chapters 1 (Sections l. l-1. 3 and 1. 6), 2, 3, 4, portions of 5 (information on Lp spaces), and portions of 7 (left to the discretion of the teacher). (b) A one-year course in 'Functional Analysis' utilizing Chapters 1 (Sections 1. 4-1. 6), 5, 6, 7 (Sections 7. 4 and 7. 6), and the Ap pendix. t T. M.

The Institute was held at Centro 'I Cappuccini' San Miniato, Tuscany, July 11-21, 1984. The Europhysics School of Quantum Electronics was started in 1970 with the aim of providing instruction for young researchers and advanced students already engaged in the area of quantum electronics or for those wishing to switch into this area after working previously in other areas. From the outset, the School has been under the direction of Prof. F. T. Arecchi, then at the University of Pavia, now at the University of Florence, and Dr. D. Roess of Heraeus, Hanau. In 1981, Prof. H. Walther, University of Munich and Max-Planck Institut fur Quantenoptik joined as co-director. Each year the Directors choose a subj~ct of particular interest, alternating fundamental topics with technological ones, and ask colleagues specifically competent in the chosen areas to take the scientific responsibility for that course. 508 pp. Englisch.
