Polysiloxanes are the most studied inorganic and semi-inorganic polymers because of their many medical and commercial uses. The Si-O backbone endows polysiloxanes with intriguing properties: the strength of the Si-O bond imparts considerable thermal stability, and the nature of the bonding imparts low surface free energy. Prostheses, artificial organs, objects for facial reconstruction, vitreous substitutes in the eyes, and tubing take advantage of the stability and pliability of polysiloxanes. Artificial skin, contact lenses, and drug delivery systems utilize their high permeability. Such biomedical applications have led to biocompatibility studies on the interactions of polysiloxanes with proteins, and there has been interest in modifying these materials to improve their suitability for general biomedical application. Polysiloxanes examines novel aspects of polysiloxane science and engineering, including properties, work in progress, and important unsolved problems. The volume, with ten comprehensive chapters, examines the history, preparation and analysis, synthesis, characterization, and applications of these polymeric materials.

Containing over 6,000 entries from Aalto to Zwinger and written in a clear and concise style, this authoritative dictionary covers architectural history in detail, from ancient times to the present day. It also includes concise biographies of hundreds of architects from history (excluding living persons), from Sir Francis Bacon and Imhotep to Liang Ssu-ch'eng and Francis Inigo Thomas. The text is complemented by over 260 beautiful and meticulous line drawings, labelled cross-sections, and diagrams. These include precise drawings of typical building features, making it easy for readers to identify particular period styles. This third edition of The Oxford Dictionary of Architecture has been extensively revised and expanded, with over 900 new entries including hundreds of definitions of garden and landscape terms such as Baroque garden, floral clock, hortus conclusus, and Zen garden-design. Each entry is followed by a mini-bibliography, with suggestions for further reading. The full bibliography to the first edition (previously only available online) has also been fully updated and expanded, and incorporated into this new edition. This is an essential work of reference for anyone with an interest in architectural and garden history. With clear descriptions providing in-depth analysis, it is invaluable for students, professional architects, art historians, and anyone interested in architecture and garden design, and provides a fascinating wealth of information for the general reader.
With this study the cattle guard joins the sod house, the windmill, and barbed wire as a symbol of range country on the American Great Plains. A U.S. folk innovation now in use throughout the world, the cattle guard functions as both a gate and a fence: it keeps livestock from crossing, but allows automobiles and people to cross freely. The author blends traditional history and folklore to trace the origins of the cattle guard and to describe how, in true folk fashion, the device in its simplest form—wooden poles or logs spaced in parallel fashion over a pit in the roadway—was reinvented and adapted throughout livestock country Hoy traces the origins of the cattle guard to flat stone stiles unique to Cornwall, England, then through the railroad cattle guard, in use in this country as early as 1836, and finally to the Great Plains where, probably in 1905, the first ones appeared on roads. He describes regional variations in cattle guards and details unusual types. He provides information on cattle-guard makers, who range from local blacksmiths and welders to farmers and ranchers to large manufacturers. In addition to documenting the economic and cultural significance of the cattle guard, this volume reveals much about early twentieth-century farm and ranch life. It will be of interest not only to folklorists and historians of agriculture and Western America, but also to many Plains-area farmers, ranchers, and oilmen.
