Windship Technology, Part A contains the proceedings of the International Symposium on Windship Technology (WINDTECH '85), held at the University of Southampton, England, on April 24-25, 1985. The symposium provided a forum for discussing developments in windship technology, including the use of calculation methods to analyze wind propulsion on cargo ships and weather routing for wind-assisted ships. Measurements of the comparative performance of sailing rigs are also presented.

Comprised of 17 chapters, this volume begins by tracing the revival of serious interest in the possible use of the wind in ship propulsion over the past decade, and giving examples of the wide range of rigs that have been developed and are now installed on ships. The reader is then introduced to Project INDOSAIL intended to develop cargo sailing vessels for the Indonesian inter-island trade. Subsequent chapters focus on sail-assist developments from 1979 to 1984; economic aspects of the application of additional sail power on small German fishing vessels; sail retrofit on inter-island vessels in Fiji; and the aerodynamics of a triangular jib-and-boom combination. The book concludes with an evaluation of two-dimensional sail shape determined by pressure and its tension.

This book will appeal to government officials, academics, ship owners, and other parties with an interest in windship technology.

Witchcraft continued provides an important collection of essays on the nature and understanding of witchcraft and magic in European society over the last two centuries. It innovatively brings together the interests of historians in nineteenth-century witchcraft and the twentieth-century fieldwork of anthropologists and sociologists on the continued relevance of witch beliefs. The book covers England, the Netherlands, Spain, Italy, Germany, France, Finland, Transylvania and Northern Ireland. It examines the experience of and attitudes towards witchcraft from both above and below. They demonstrate the widespread fear of witches amongst the masses during the nineteenth century, and the continued but more restricted relevance of witchcraft in the twentieth century. While the educated classes generally denounced witch-believers as either superstitious, foolish or both, secular and religious authorities still had to find strategies of dealing with the demands of those who believed themselves the victims of witchcraft. Moreover the rise of the folklore movement and the growth of anthropology as an academic discipline over the period provided a huge body of evidence on continuing beliefs that many had consigned to the past. This book will be essential reading for those interested in the continued importance of witchcraft and magic in the modern era. More generally it will appeal to those with a lively interest in the cultural history of the nineteenth and twentieth centuries.

Refineries and petrochemical engineers today are accepting more unconventional feedstocks such as heavy oil and shale, causing unique challenges on the processing side of the business. To create more reliable engineering design of process equipment for the petrochemical industry, petroleum engineers and process managers are forced to study the physical properties and compounds of these particular hydrocarbons. Instead of looking up each compound’s information, The Yaws Handbook of Physical Properties for Hydrocarbons and Chemicals, Second Edition presents an easy-to-use format with rapid access to search for the particular compound and understand all the complex calculations in one tabular format. Understanding the composition of hydrocarbons is not easy to calculate quickly or accurately, but this must-have reference leads the engineer to better estimated properties and fractions from easily measured components. Expanded to cover more total compounds and relevant functions, The Yaws Handbook of Physical Properties for Hydrocarbons and Chemicals, Second Edition remains a necessary reference tool for every petrochemical and petroleum engineers’ library.

• Coverage added on elements for hydrocarbons and chemicals with more than 200 real-world cases included for practicality
• Increased compound coverage from 41,000 to 54,000 total compounds to quickly access for everyday use
• New functions added such as testing boiling point temperature and new data on density and refractory index
