"In the second half of the twentieth century, Reiki went from an obscure therapy practiced by a few thousand Japanese and Japanese Americans to a global phenomenon. By the early twenty-first century, people in nearly every corner of the world have undergone the initiations that authorize them to channel a cosmic energy--known as Reiki--to heal body, mind, and spirit. They lay hands on themselves and others, use secret symbols and incantations to send Reiki to distant recipients, and strive to follow five precepts to cultivate their spiritual growth. Reiki's international rise and development is due to the work of Hawayo Takata (1900-1980), a Hawai°i-born Japanese American woman who brought Reiki out of Japan and adapted it for thousands of students in Hawai°i and North America, shaping interconnections across the North Pacific region as well as cultural transformations over the transwar period spanning World War II. Alternate Currents: Reiki's Circulation in the Twentieth-Century North Pacific analyzes how, from her training in Japan in the mid-1930s to her death in Iowa in 1980, Takata built a vast trans-Pacific network that connected Japanese American laborers on Hawai°i plantations to social elites in Tokyo, Hollywood, and New York; middle class housewives in American suburbs; and off-the-grid tree planters in the mountains of British Columbia. Using recently uncovered archival materials and original oral histories, Stein examines how these relationships between healer and patient, master and disciple, became deeply infused with values of their time and place and how they interplayed with Reiki's circulation, performance, and meanings along with broader cultural shifts in the twentieth-century North Pacific. Highly readable and informative, each chapter is structured around a period in the life of Takata, the charismatic, rags-to-riches architect of the network in which Reiki spread for decades. Alternate Currents explores Reiki as an exemplary transnational spiritual therapy, demonstrating how lived practices transcend artificial distinctions between religion and medicine, and circulate in global systems while maintaining strong connections with the practices' homeland"--

Electrical codes, standards, recommended practices and regulations can be complex subjects, yet are essential in both electrical design and life safety issues.This book demystifies their usage.It is a handbook of codes, standards, recommended practices and regulations in the United States involving electrical safety and design. Many engineers and electrical safety professionals may not be aware of all of those documents and their applicability. This book identifies those documents by category, allowing the ready and easy access to the relevant requirements. Because these documents may be updated on a regular basis, this book was written so that its information is not reliant on the latest edition or release of those codes, standards, recommended practices or regulations.No single document on the market today attempts to not only list the majority of relevant electrical design and safety codes, standards, recommended practices and regulations, but also explain their use and updating cycles. This book, one-stop-information-center for electrical engineers, electrical safety professionals, and designers, does. - Covers the codes, standards, recommended practices and regulations in the United States involving electrical safety and design, providing a comprehensive reference for engineers and electrical safety professionals - Documents are identified by category, enabling easy access to the relevant requirements - Not version-specific; information is not reliant on the latest edition or release of the codes, standards, recommended practices or regulations

This book outlines a path that, in addition to providing the necessary foundation for dealing with the study of AC systems, allows an overview and an introduction to some of the powerful mathematical ideas and methods, fundamental to many areas of current science and technology. Besides a theoretical review for the practitioner, it can be profitably used as a bridge in the transition from high-school mathematics to specialized university courses. This is why the reader is accompanied on the journey by "mathematical interludes," in which he/she will find useful reminders and insights. It also constitutes a cultural proposal dedicated to all those who, like I. Newton, holding between two fingers the grain of their knowledge, always see, in the background, the ocean of the unknown. 1 - SINUSOIDAL ELECTRICAL QUANTITIES 2 - SINUSOIDS, PHASORS AND COMPLEX NUMBERS 3 - IMPEDANCE AND REACTANCE 4 - ADMITTANCE AND A.C.
