Taschenbuch. Condición: Neu. Neuware - This book covers the most recent development of enzymatic organic synthesis, with particular focus on the use of isolated enzymes. It is organized into one introductory chapter dealing with the characteristics of enzymes as catalysts, and five chapters dealing with different types of chemical transformations. Methods for enzyme immobilization and stabilizaton, the use of enzymes in extreme environments, and the alteration of enzyme properties by chemical modification and site-directed mutagenesis for synthetic purposes are covered.…

Buch. Condición: Neu. Neuware - The first volume in a series which aims to focus on advances in computational biology. This volume discusses such topics as: fluctuations in the shape of flexible macromolecules; the hydration of carbohydrates as seen by computer simulation; and studies of salt-peptide solutions.…

Buch. Condición: Neu. Neuware - After a decade of dominance by recombinant DNA technology, the field of molecular and cell biology is witnessing a renewed interest in techniques and approaches that are not driven by DNA acrobatics. In hindsight, this is an inevitable outcome. Deoxyribonucleic acid is not the master; it is only a storage house. If one wishes to know how cells work, the secret is not to be found in DNA, but rather in everything outside DNA. Science based on DNA is useful but does not itself solve the problem. It is most fortunate that at the height of the DNA phenomenon, there remain scientists who continue to probe cells by non-DNA means. Suddenly, people with such expertise are in high demand. In this volume, some truly original scientists take the time to tell us their stories of innovations-some almost iconoclastic. All of these researchers have pioneered approaches that were long neglected; moreover, each is now in the fruitful phase of great harvests. It is a wonderful lesson for graduate students and postdoctorates that, although not being in the pack might be risky, the reward of such work is sweeter. As in physics, biology needs more young people who think like Richard Feynman - the ultimate iconoclast. On the surface, the eight chapters of this volume appear to be diverse, but they are not. If our purpose is to understand cells, we must stop the habit of constantly dissecting leaves. Once in a while we have to see which forest we are in. The contributions included herein cannot cover the whole cell, but they give a sufficient flavor to arouse a desire to think more globally about cells. At a time when our field is in danger of being buried by thousands of kinases and phosphatases, these chapters inform our intended audiences that there are other ways - other techniques, other approaches, other thinkings, and other stories. We need all of them to appreciate the holistic aspect of cells, which has been a taboo until now.…

Buch. Condición: Neu. Neuware - Modern ceramic materials differ from the traditional materials which were only based on natural substances. It is now possible to prepare ceramics using a wide range of properties and as an area this field has evolved as a very broad scientific and technical field in its own right. In practice one encounters ceramics in practically all branches of materials science and the characteristics are so wide ranging that the common basis of these substances is not always immediately apparent. All ceramic materials are prepared by ceramic technology, and powder substances are used as the initial raw materials. Their physical properties are an expression not only of their composition, but primarily of their structure. Thus in order to fully understand the properties of ceramics, a knowledge of their structure is essential. This book is intended as a source of such knowledge. All the chapters are written by authors with vast experience in the various fields of ceramics who provide a detailed description of the interrelationships between the structure and behaviour of ceramic materials.…
