Book Description
In this thesis, the author describes the total synthesis of natural product Maoecrystal V in detail. In the first part of the thesis, the author introduces the research background and reviews the research progress in total synthesis of Maoecrystal V. In the second part, the author develops a novel and concise approach for the stereo selective construction of the tetracyclic model system of Maoecrystal V. The model system is accomplished in 8 steps with 20% yield. In the third part, the author describes the first successful total synthesis of Maoecrystal V and investigates four strategies for constructing the key tetrahydrofuran oxa-bridge skeleton. The total synthesis starts from a known compound and is accomplished in 17 steps with 1.2% yield. The successful total synthesis of Maoecrystal V will contribute to the development of efficient synthetic strategies for natural products and other compounds with complex structures.

Book Description
Research in the pharmaceutical industry today is in many respects quite different from what it used to be only fifteen years ago. There have been dramatic changes in approaches for identifying new chemical entities with a desired biological activity. While chemical modification of existing leads was the most important approach in the 1970s and 1980s, high-throughput screening and structure-based design are now major players among a multitude of methods used in drug discov ery. Quite often, companies favor one of these relatively new approaches over the other, e.g., screening over rational design, or vice versa, but we believe that an intelligent and concerted use of several or all methods currently available to drug discovery will be more successful in the medium term. What has changed most significantly in the past few years is the time available for identifying new chemical entities. Because of the high costs of drug discovery projects, pressure for maximum success in the shortest possible time is higher than ever. In addition, the multidisciplinary character of the field is much more pronounced today than it used to be. As a consequence, researchers and project managers in the pharmaceutical industry should have a solid knowledge of the more important methods available to drug discovery, because it is the rapidly and intelligently combined use of these which will determine the success or failure of preclinical projects.

Book Description
Bridging the fields of conservation, art history, and museum curating, this volume contains the principal papers from an international symposium titled "Historical Painting Techniques, Materials, and Studio Practice" at the University of Leiden in Amsterdam, Netherlands, from June 26 to 29, 1995. The symposium—designed for art historians, conservators, conservation scientists, and museum curators worldwide—was organized by the Department of Art History at the University of Leiden and the Art History Department of the Central Research Laboratory for Objects of Art and Science in Amsterdam. Twenty-five contributors representing museums and conservation institutions throughout the world provide recent research on historical painting techniques, including wall painting and polychrome sculpture. Topics cover the latest art historical research and scientific analyses of original techniques and materials, as well as historical sources, such as medieval treatises and descriptions of painting techniques in historical literature. Chapters include the painting methods of Rembrandt and Vermeer, Dutch 17th-century landscape painting, wall paintings in English churches, Chinese paintings on paper and canvas, and Tibetan thangkas. Color plates and black-and-white photographs illustrate works from the Middle Ages to the 20th century.

Book Description
Greatly revised and expanded, with a new afterword, this update to Martin Jacques’s global bestseller is an essential guide to understanding a world increasingly shaped by Chinese power Soon, China will rule the world. But in doing so, it will not become more Western. Since the first publication of When China Rules the World, the landscape of world power has shifted dramatically. In the three years since the first edition was published, When China Rules the World has proved to be a remarkably prescient book, transforming the nature of the debate on China. Now, in this greatly expanded and fully updated edition, boasting nearly 300 pages of new material, and backed up by the latest statistical data, Martin Jacques renews his assault on conventional thinking about China’s ascendancy, showing how its impact will be as much political and cultural as economic, changing the world as we know it. First published in 2009 to widespread critical acclaim - and controversy - When China Rules the World: The End of the Western World and the Birth of a New Global Order has sold a quarter of a million copies, been translated into eleven languages, nominated for two major literary awards, and is the subject of an immensely popular TED talk.

Book Description
From the bestselling author of The Ascent of Money and The Square and the Tower “A dazzling history of Western ideas.” —The Economist “Mr. Ferguson tells his story with characteristic verve and an eye for the felicitous phrase.” —Wall Street Journal “[W]ritten with vitality and verve . . . a tour de force.” —Boston Globe Western civilization’s rise to global dominance is the single most important historical phenomenon of the past five centuries. How did the West overtake its Eastern rivals? And has the zenith of Western power now passed? Acclaimed historian Niall Ferguson argues that beginning in the fifteenth century, the West developed six powerful new concepts, or “killer applications”—competition, science, the rule of law, modern medicine, consumerism, and the work ethic—that the Rest lacked, allowing it to surge past all other competitors. Yet now, Ferguson shows how the Rest have downloaded the killer apps the West once monopolized, while the West has literally lost faith in itself. Chronicling the rise and fall of empires alongside clashes (and fusions) of civilizations, Civilization: The West and the Rest recasts world history with force and wit. Boldly argued and teeming with memorable characters, this is Ferguson at his very best.
