The new edition of Rowan’s Primer of EEG continues to provide clear, concise guidance on the difficult technical aspects of how to perform and interpret EEGs. Practical yet brief, it is perfectly suited for students, residents, and neurologists alike. Included reference material will be continually useful, even to the experienced epileptologist.

Maurice Yacowar challenges genre and form in Roy & Me, a cross between memoir and fiction, truth and distortion. It is the exploration of Yacowar’s relationship with Roy Farran—soldier, politician, author, mentor—and his conflict with Farran’s anti-Semitic past. Best known for his service with the British Special Air Service during World War II, Roy Farran served as a politician in the Legislative Assembly of Alberta for Premier Peter Lougheed. During his time in Israel as a soldier, Farran allegedly kidnapped and murdered a sixteen-year-old member of the Lehi group, also known as the Stern Gang.

"In recent decades the history of premodern states and empires has undergone major revision. At the heart of this process stood the court, encompassing the household as well as government institutions. This volume for the first time brings together the fruits of research on royal courts from antiquity to the modern world, from Asia to Europe. The authors are acknowledged specialists in their own fields, but they address themes relevant for all courts: the inner and outer dimensions of court architecture as well as staff organizations; the connections between court, capital, and realm; the relationship of the ruler with relatives and other elites. This volume pioneers comparative history combining a rich empirical orientation with a critical assessment of theoretical perspectives. Contributors: Tülay Artan, Gojko Barjamovic, Peter Fibiger Bang, Jeroen Duindam, Sabine Dabringhaus, Nadia Maria El Cheikh, Ebba Koch, Metin Kunt, Paul Magdalino, Rosamond McKitterick, Ruth Macrides, Rolf Strootman, Isenbike Togan, Maria Antonietta Visceglia, and Andrew Wallace-Hadrill."

Rubber Seals for Fluid and Hydraulic Systems is a comprehensive guide to the manufacturing and applications of rubber seals, with essential coverage for industry sectors including aviation, oil drilling and the automotive industry.

Fluid leakage costs industry millions of dollars every year. In addition to wasted money, unattended leaks can result in downtime, affect product quality, pollute the environment, and cause injury. Successful sealing involves containment of fluid within a system while excluding the contaminants; the resilience of rubber enables it to be used to achieve these two objectives and create a tight sealing effect. A sound understanding of the complex factors involved in successful fluid sealing is essential for engineers who specify, design, operate and maintain machinery and mechanical equipment.

This book focuses on the characteristics of rubbers as seals, their manufacturing procedures, the implications of their physical and chemical characteristics for the sealing function in the fluid and hydraulic systems, how rubbers seal and prevent leaks, what properties are required for sealing function, and how they change before and after installation.

The chapter on Manufacture of Seals and ‘O’Rings includes approximately 25 workable starting point formulations based on different rubbers, with cure and property data of those formulations as guidelines for technologists and engineers.

• Emphasis on important areas such as applications of rubber as fluid seals in the nuclear, aviation, oil drilling and automotive industries
• Includes a chapter on Rubber Expansion Joints as the function of such expansion joints as pipe connectors is indirectly linked with leakage and prevention of fluid flow through the pipes
• The chapter on Manufacture of Seals and ‘O’Rings includes approx. 25 workable starting point formulations based on different rubbers, with cure and property data of those formulations as guidelines for technologists and engineers

This article is concerned with cosmological concepts of the peoples of Polynesia in the Pacific. Following a creation myth from Tahiti, the authors explore the realms of te ao (the world of space and light which came to be inhabited by humans) and te po (the engulfing darkness, associated with the night, the ancestors and spirits) by investigating artefacts from the region. Certain qualities of the rare materials used in the highly skilled making, and the knowledge of the utilisation of these artefacts enabled pacific islanders to establish a connection to divine entities but also to protect themselves of their powers. Many of the cosmological principles finally can be rediscovered in the objects themselves, which therefore are a study of the cosmos in miniature.
