Download or read book Managing Complex Service Systems written by Richard Taylor and published by Springer. This book was released on 2009-05-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book establishes and communicates a scientific approach to the analysis, design and management of complex information systems enabled services. Case studies illustrate how the techniques described can be employed in large scale, real world examples that are developed to match the theoretical and practical presentation. The authors reframe the problem of analyzing a complex service system from an `understand the system' view to an `understand it under control' perspective. This fundamental change recognizes that service systems are largely constructed and should be treated differently from natural systems, something that has typically been ignored in the past. By shifting to a view in which the systems dynamics over the full range of significant factors -- people, the economic and physical environments, as well as technology options -- are understood, many of the pitfalls that have sunk large projects in the past can be avoided.

Download or read book Molecular Structure and Biological Activity of Steroids written by Martin Bohl and published by CRC Press. This book was released on 2018-01-18 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Structure and Biological Activity of Steroids focuses on the indentification of steroid structural features that control particular biological effects. Steroid geometry plays a critical role in steroid activity; therefore, the results of X-ray crystallographic, NMR spectroscopic, and theoretical studies on structure-activity relationships form an integral part of the book. Well-established observations and proposed models are presented, summarizing knowledge of molecular features (e.g., steroid backbone structures, side-chain constitutions, substitution sites, configurations, hydrogen-bonding patterns) that can affect steroid action. The book also provides overviews about recent progress in various frontier fields of steroid research, including such areas as sex steroids, glucocorticoids, aromatase inhibitors, vitamin D metabolites, brassinosteroids, neuromuscular blocking agents, and cardiotonic steroids. Molecular Structure and Biological Activity of Steroids is a "must-have" resource for biochemists, pharmacologists, endocrinologists, biophysicists, and others actively involved in steroid research.
Download or read book 3D QSAR in Drug Design written by Hugo Kubinyi and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant progress has been made in the study of three-dimensional quantitative structure-activity relationships (3D QSAR) since the first publication by Richard Cramer in 1988 and the first volume in the series. 3D QSAR in Drug Design. Theory, Methods and Applications, published in 1993. The aim of that early book was to contribute to the understanding and the further application of CoMFA and related approaches and to facilitate the appropriate use of these methods. Since then, hundreds of papers have appeared using the quickly developing techniques of both 3D QSAR and computational sciences to study a broad variety of biological problems. Again the editor(s) felt that the time had come to solicit reviews on published and new viewpoints to document the state of the art of 3D QSAR in its broadest definition and to provide visions of where new techniques will emerge or new appli- tions may be found. The intention is not only to highlight new ideas but also to show the shortcomings, inaccuracies, and abuses of the methods. We hope this book will enable others to separate trivial from visionary approaches and me-too methodology from in- vative techniques. These concerns guided our choice of contributors. To our delight, our call for papers elicited a great many manuscripts.
Download or read book Handbook of Molecular Descriptors written by Roberto Todeschini and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative studies on structure-activity and structure-property relationships are powerful tools in directed drug research. In recent years, various strategies have been developed to characterize and classify structural patterns by means of molecular descriptors. It has become possible not only to assess diversities or similarities of structure databases, but molecular descriptors also facilitate the identification of potential bioactive molecules from the rapidly increasing number of compound libraries. They even allow for a controlled de-novo design of new lead structures. This is the most comprehensive collection of molecular descriptors and presents a detailed review from the origins of this research field up to present day. This practically oriented reference book gives a thorough overview of the different molecular descriptors representations and their corresponding molecular descriptors. All descriptors are listed with their definition, symbols and labels, formulas, some numerical examples, data and molecular graphs, while numerous figures and tables aid comprehension of the definitions. Cross-references throughout, a list of acronyms and notations allow easy access to the information needed to solve a specific research problem. Examples of descriptor calculations along with tables of descriptor values for a set of selected reference compounds and an up-to-date reference list add to the practical value of the book, making it an invaluable guide for all those dealing with bioactive molecules as well as for researchers.
