Найти книгу: "Retrosynthetic Analysis and Synthesis of Natural Products 1"

For chemists, attempting to mimic nature by synthesizing complex natural products from raw material is a challenge that is fraught with pitfalls. To tackle this unique but potentially rewarding task, researchers can rely on well-established reactions and methods of practice, or apply their own synthesis methods to verify their potential. Whatever the goal and its complexity, there are multiple ways of achieving it. We must now establish a strategic and effective plan that requires the minimum number of steps, but lends itself to widespread use. This book is structured around the study of a dozen target products (butyrolactone, macrolide, indole compound, cyclobutanic terpene, spiro- and polycyclic derivatives, etc. ). For each product, the different disconnections are presented and the associated syntheses are analyzed step by step. The key reactions are described explicitly, followed by diagrams showing the range of impact of certain transformations. This set of data alone is conducive to understanding syntheses and indulging in this difficult, but worthwhile activity.

Книга, написанная разработчиками Microsoft SQL Server 2005 Analysis Services, дает читателю полное представление об его функционировании и устройстве. В ней рассмотрены основы многомерного анализа данных и дано глубокое представление о многомерных моделях данных и устройстве OLAP-сервера. Описаны основные концепции языка доступа к многомерным данным MDX и его расширенные возможности, а также архитектура сервера, методы обработки данных и алгоритмы доступа к данным. Приведены внутренние и внешние протоколы обмена данными, включая протокол XML/A. Рассмотрены алгоритмы управления ресурсами Analysis Services, в том числе алгоритмы управления памятью. Описан процесс создания эффективных клиентских приложений с использованием Analysis Services, механизмы интеграции многомерных и реляционных баз данных. Уделено внимание безопасности, а также администрированию Microsoft SQL Server 2005 Analysis Services. Для разработчиков и бизнес-аналитиков.
