Buch. Condizione: Neu. Neuware -More than anything else, this book is a tribute to Edsger W. Dijkstra, on the occasion of his sixtieth birthday, by just a few of those fortunate enough to be influenced by him and his work and to be called his friend or relation, his master, colleague, or pupil. This book contains fifty-four technical contributions in different areas of endeavor, although many of them deal with an area of particular concern to Dijkstra: programming. Each contribution is relatively short and could be digested in one sitting. Together, they form a nice cross section of the discipline of programming at the beginning of the nineties. While many know of Dijkstra's technical contributions, they may not be aware of his ultimate goal, the mastery of complexity in mathematics and computing science. He has forcefully argued that beauty and elegance are essential to this mastery. The title of this book, chosen to reflect his ultimate goal, comes from a sentence in an article of his on some beautiful arguments using mathematical induction: '. when we recognize the battle against chaos, mess, and unmastered complexity as one of computing sci- ence's major callings, we must admit that 'Beauty Is Our Business'.' 480 pp. Englisch.

Buch. Condizione: Neu. Neuware -The calcified tissues have fundamental functions in the biology of organisms, not only because their strength, solidity, and elasticity permit movement and mechanical activities, and protect soft tissues against traumatic forces, but also on account of their role in mineral homeostasis. For this reason, extensive investigation in the last 30 years has provided much to explain the complex chemical and physical processes occurring in cells and matrices composing the skeleton, and their alterations in pathological conditions. The use of ultrastructural methods such as immunocytochemistry, scanning and transmission electron microscopy, cytoautoradiography, freeze/fracture etching, high voltage, etc. has proven to be of great value when applied to cells and matrix components of bone and cartilage, in spite of the technical difficulties due to the hardness of these tissues. However, available information on this subject is disseminated in a variety of scientific and medical articles. This volume is an attempt to collect together the most significant data on the ultrastructure of cartilage and bone in normalcy and pathology. Obviously, it cannot be a complete report of all these data, its principal aim being that of: a) giving a comprehensive statement of the results concerning the basic structures common to these tissues, especially collagen fibrils, noncollagenous proteins, and proteoglycans, and their relationships with the mineral substance (for which another volume of this series can also be consulted; see Ruggeri A. , Motta P. M. (eds. 316 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book is directed at advanced undergraduate and postgraduate students-and their teachers-who are involved in those areas of cell biology which require a basic knowledge of cytoskeletal structure, parti cularly with respect to cell motility. It contains a core of basic information on the cytoskeleton and focuses especially on its functional aspects, from the swimming of spermatozoa to the crawling of cultured cells across their culture dish; from the transport of vesicles and organelles along nerve axons, to the orderly segregation of chromosomes at mitosis. Cytoskeleton research spans a wide range of scientific disciplines. It is as important for students or research workers investigating, for example, the deposition of the higher plant cell wall to have easy access to a core of basic information regarding microtubules as it is for someone interested in endocytosis and the fate of cell surface receptors. The authors are involved in the teaching of the cytoskeleton and cell motility at all levels of undergraduate study at University College London, but each has a research interest in different aspects of the subject: TMP in amoeboid locomotion, CAK in gliding motility and JSH in cilia, flagella and mitosis.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For several decades the electron microscope has been the instrument of choice for the examination of biological structures at high resolution. Biologists have be come familiar with the techniques and pitfalls of sample preparation and with the interpretation of the images obtained. The purpose of this book is to introduce the biologist to a number of new imaging techniques that are now becoming avail able to supplement and even extend the information that can be obtained from the now-traditional electron microscope. Some of these techniques are still at the experimental stage, while others, such as cryoelectron microscopy and confocal optical microscopy, are at advanced stages of development and are already avail able commercially. This book represents a first attempt to quantify the progress made by bring ing together, in one volume, an account of the technical bases and the future potentials of the various techniques. Although the content is primarily aimed at biologists, microscopists in other fields should also find the information of interest and use. All the chapters are written by leading experts who are at the forefront of these exciting developments. About half the book is concerned with x-ray microscopy; the editors make no apology for this since they are both intimately involved with developments associated with this field and therefore view it, perhaps with bias, as being of the utmost importance. 292 pp. Englisch.
