Book Description
Undeservedly little attention is paid in the vast literature on the theories of vibration and plasticity to the problem of steady-state vibrations in elastoplastic bodies. This problem, however, is of considerable interest and has many important applications. The problem of low-cyclic fatigue of metals, which is now in a well de veloped state is one such application. The investigations within this area are actually directed to collecting experimental facts about repeated cyclic loadings, cf. [47J. Theoretical investigations within this area usually con sider the hysteretic loops and the construction of models of plasticity theory which are applicable to the analysis of repeated loadings and the study of the simplest dynamic problems. Another area of application of the theory of the vibration of elastoplas tic bodies is the applied theory of amplitude-dependent internal damping. Another name for this theory is the theory of energy dissipation in vibrat ing bodies. In accordance with the point of view of Davidenkov "internal damping" in many metals, alloys and structural materials under consider able stress presents exactly the effect of micro plastic deformations. There fore, it may be described by the methods of plasticity theory. This point of view is no doubt fruitful for the theory of energy dissipation in vibrating bodies, as it allows one to write down the constitutive equations appropri ate both for vibrational analysis of three-dimensional stress states and an investigation of nonharmonic deformation. These problems are known to be important for the theory of internal damping.

Book Description
“Guides readers toward the road less consumptive, offering practical advice and moral support while making a convincing case that individual actions . . . do matter.” —Elizabeth Royte, author, Garbage Land and Bottlemania Like many people, Beth Terry didn’t think an individual could have much impact on the environment. But while laid up after surgery, she read an article about the staggering amount of plastic polluting the oceans, and decided then and there to kick her plastic habit. In Plastic-Free, she shows you how you can too, providing personal anecdotes, stats about the environmental and health problems related to plastic, and individual solutions and tips on how to limit your plastic footprint. Presenting both beginner and advanced steps, Terry includes handy checklists and tables for easy reference, ways to get involved in larger community actions, and profiles of individuals—Plastic-Free Heroes—who have gone beyond personal solutions to create change on a larger scale. Fully updated for the paperback edition, Plastic-Free also includes sections on letting go of eco-guilt, strategies for coping with overwhelming problems, and ways to relate to other people who aren’t as far along on the plastic-free path. Both a practical guide and the story of a personal journey from helplessness to empowerment, Plastic-Free is a must-read for those concerned about the ongoing health and happiness of themselves, their children, and the planet.

Book Description
In Plastic Bodies Emilia Sanabria examines how sex hormones are enrolled to create, mold, and discipline social relations and subjectivities. She shows how hormones have become central to contemporary understandings of the body, class, gender, sex, personhood, modernity, and Brazilian national identity. Through interviews with women and doctors; observations in clinics, research centers and pharmacies; and analyses of contraceptive marketing, Sanabria traces the genealogy of menstrual suppression, from its use in population control strategies in the global South to its remarketing as a practice of pharmaceutical self-enhancement couched in neoliberal notions of choice. She links the widespread practice of menstrual suppression and other related elective medical interventions to Bahian views of the body as a malleable object that requires constant work. Given this bodily plasticity, and its potentially limitless character, the book considers ways to assess the values attributed to bodily interventions. Plastic Bodies will be of interest to all those working in medical anthropology, gender studies, and sexual and reproductive health.

Book Description
Controversial, fascinating, disturbing, and often beautiful, plastinated human bodies -- such as those found at Body Worlds exhibitions throughout the world -- have gripped the public's imagination. These displays have been lauded as educational, sparked protests, and drawn millions of visitors. This book looks at the powerful sway these corpses hold over their living audiences everywhere. Plastination was invented in the 1970s by German anatomist Gunther von Hagens. The process transforms living tissues into moldable plastic that can then be hardened into a permanent shape. Von Hagens first exhibited his expertly dissected, artfully posed plastinated bodies in Japan in 1995. Since then, his shows have continuously attracted so many paying customers that they have inspired imitators, brought accusations of unethical or even illegal behavior, and ignited vigorous debates among scientists, educators, religious leaders, and law enforcement officials. These lively, thought-provoking, and sometimes personal essays reflect on such public displays from ethical, legal, cultural, religious, pedagogical, and aesthetic perspectives. They examine what lies behind the exhibitions' popularity and explore the ramifications of turning corpses into a spectacle of amusement. Contributions from bioethicists, historians, physicians, anatomists, theologians, and novelists dig deeply into issues that compel, upset, and unsettle us all.

Book Description
Alongside readings of Merleau-Ponty and Levinas, Plastic Bodies digs into an array of ancient, modern, and contemporary texts in search of the resources needed to rebuild the concept of sensation. It assembles a speculative aesthetics that is both a realist theory of sensation and a philosophy of embodiment that breaks the form of the "lived" body.

Book Description
South Korea represents one of the world's most enthusiastic markets for plastic surgery. The growth of this market is particularly fascinating as access to medical care and surgery arose only recently with economic growth since the 1980s. Reconstructing Bodies traces the development of a medical infrastructure in the Republic of Korea (ROK) from 1945 to the present, arguing that the plastic surgery craze and the related development of biotech ambitions is deeply rooted in historical experience. Tracking the ROK's transition and independence from Japan, John P. DiMoia explains how the South Korean government mobilized biomedical resources and technologies to consolidate its desired image of a modern and progressive nation. Offering in-depth accounts of illustrative transformations, DiMoia narrates South Korean biomedical practice, including Seoul National University Hospital's emergence as an international biomedical site, state-directed family planning and anti-parasite campaigns, and the emerging market for aesthetic and plastic surgery, reflecting how South Koreans have appropriated medicine and surgery for themselves as individuals, increasingly prioritizing private forms of health care.
