Impact Wear of Materials


Book Description

Impact Wear of Materials is entirely devoted to quantitative treatment of various forms of wear occurring in impact-loaded mechanical components. Impact wear is classified under two headings, namely `erosive' and `percussive' wear. In erosive wear, particle streams and liquid jets are discussed. The subject is developed with emphasis on material relations, stress analysis and the historical progress of research. In percussive wear, a wide variety of wear mechanisms is described.The author's experimental/analytical work created the groundwork for a general procedure of impact wear-law formulation, combining impact analysis with the physical wear mechanism. Ballistic impact and pivotal hammering, compound impact, the optimal wearpath, lubrication, plasticity, and flexible media are some of the topics considered.The book develops a new conceptual approach to impact, impact-originated wear and wear in general. It describes and utilizes the modern tools of observation in wear science. In mechanical analysis it emphasizes quantitative treatment, using such tools as finite element stress analysis, APL programming language etc., each applied with classic simplicity. Numerous photographs, tables, figures and examples are used throughout the text and the mathematical treatment strives for simplicity and conceptual clarity. The book is of value to mechanical component designers, analysts and researchers. It is also useful in science and engineering curricula at senior and graduate level and, although its appeal is primarily in tribology, machine design and materials science, its interdisciplinary language makes it accessible to any branch of the physical sciences and engineering.




Culture, Mind, and Brain


Book Description

Recent neuroscience research makes it clear that human biology is cultural biology - we develop and live our lives in socially constructed worlds that vary widely in their structure values, and institutions. This integrative volume brings together interdisciplinary perspectives from the human, social, and biological sciences to explore culture, mind, and brain interactions and their impact on personal and societal issues. Contributors provide a fresh look at emerging concepts, models, and applications of the co-constitution of culture, mind, and brain. Chapters survey the latest theoretical and methodological insights alongside the challenges in this area, and describe how these new ideas are being applied in the sciences, humanities, arts, mental health, and everyday life. Readers will gain new appreciation of the ways in which our unique biology and cultural diversity shape behavior and experience, and our ongoing adaptation to a constantly changing world.




Cultural Neuroscience: Cultural Influences on Brain Function


Book Description

This volume presents recent empirical advances using neuroscience techniques to investigate how culture influences neural processes underlying a wide range of human abilities, from perception and scene processing to memory and social cognition. It also highlights the theoretical and methodological issues with conducting cultural neuroscience research. Section I provides diverse theoretical perspectives on how culture and biology interact are represented. Sections II –VI is to demonstrate how cultural values, beliefs, practices and experience affect neural systems underlying a wide range of human behavior from perception and cognition to emotion, social cognition and decision-making. The final section presents arguments for integrating the study of culture and the human brain by providing an explicit articulation of how the study of culture can inform the study of the brain and vice versa.




Cognitive Neuroscience of Aging


Book Description

This second edition of the popular Cognitive Neuroscience of Aging provides up-to-date coverage of the most fundamental topics in this discipline. Like the first edition, this volume accessibly and comprehensively reviews the neural mechanisms of cognitive aging appropriate to both professionals and students in a variety of domains, including psychology, neuroscience, neuropsychology, neurology, and psychiatry. The chapters are organized into three sections. The first section focuses on major questions regarding methodological approaches and experimental design. It includes chapters on structural imaging (MRI, DTI), functional imaging (fMRI), and molecular imaging (dopamine PET, etc), and covers multimodal imaging, longitudinal studies, and the interpretation of imaging findings. The second section concentrates on specific cognitive abilities, including attention and inhibitory control, executive functions, memory, and emotion. The third section turns to domains with health and clinical implications, such as the emergence of cognitive deficits in middle age, the role of genetics, the effects of modulatory variables (hypertension, exercise, cognitive engagement), and the distinction between healthy aging and the effects of dementia and depression. Taken together, the chapters in this volume, written by many of the most eminent scientists as well as young stars in this discipline, provide a unified and comprehensive overview of cognitive neuroscience of aging.




Brain Culture


Book Description

Brain Culture investigates the American obsession with the health of the brain. Davi Johnson Thornton looks at familiar messages, tracing how brain science and colorful brain images produced by scientific technologies are taken up and distributed in popular media. She tracks the message that, "you are your brain" across multiple contemporary contexts, analyzing its influence on child development, family life, education, and public policy. Our fixation on the brain is not simply a reaction to scientific progress, but a cultural phenomenon tied to values of individualism and limitless achievement.




Brain and Culture


Book Description

Research shows that between birth and early adulthood the brain requires sensory stimulation to develop physically. The nature of the stimulation shapes the connections among neurons that create the neuronal networks necessary for thought and behavior. By changing the cultural environment, each generation shapes the brains of the next. By early adulthood, the neuroplasticity of the brain is greatly reduced, and this leads to a fundamental shift in the relationship between the individual and the environment: during the first part of life, the brain and mind shape themselves to the major recurring features of their environment; by early adulthood, the individual attempts to make the environment conform to the established internal structures of the brain and mind. In Brain and Culture, Bruce Wexler explores the social implications of the close and changing neurobiological relationship between the individual and the environment, with particular attention to the difficulties individuals face in adulthood when the environment changes beyond their ability to maintain the fit between existing internal structure and external reality. These difficulties are evident in bereavement, the meeting of different cultures, the experience of immigrants (in which children of immigrant families are more successful than their parents at the necessary internal transformations), and the phenomenon of interethnic violence. Integrating recent neurobiological research with major experimental findings in cognitive and developmental psychology—with illuminating references to psychoanalysis, literature, anthropology, history, and politics—Wexler presents a wealth of detail to support his arguments. The groundbreaking connections he makes allow for reconceptualization of the effect of cultural change on the brain and provide a new biological base from which to consider such social issues as "culture wars" and ethnic violence.

Mind Shift


Book Description

John Parrington argues that social interaction and culture have deeply shaped the exceptional nature of human consciousness. The mental capacities of the human mind far outstrip those of other animals. Our imaginations and creativity have produced art, music, and literature; built bridges and cathedrals; enabled us to probe distant galaxies, and to ponder the meaning of our existence. When our minds become disordered, they can also take us to the depths of despair. What makes the human brain unique, and able to generate such a rich mental life? In this book, John Parrington draws on the latest research on the human brain to show how it differs strikingly from those of other animals in its structure and function at a molecular and cellular level. And he argues that this 'shift', enlarging the brain, giving it greater flexibility and enabling higher functions such as imagination, was driven by tool use, but especially by the development of one remarkable tool - language. The complex social interaction brought by language opened up the possibility of shared conceptual worlds, enriched with rhythmic sounds, and images that could be drawn on cave walls. This transformation enabled modern humans to leap rapidly beyond all other species, and generated an exceptional human consciousness, a sense of self that arises as a product of our brain biology and the social interactions we experience. Our minds, even those of identical twins, are unique because they are the result of this extraordinarily plastic brain, exquisitely shaped and tuned by the social and cultural environment in which we grew up and to which we continue to respond through life. Linking early work by the Russian psychologist Lev Vygotsky to the findings of modern neuroscience, Parrington explores how language, culture, and society mediate brain function, and what this view of the human mind may bring to our understanding and treatment of mental illness.




The Encultured Brain


Book Description

Basic concepts and case studies from an emerging field that investigates human capacities and pathologies at the intersection of brain and culture. The brain and the nervous system are our most cultural organs. Our nervous system is especially immature at birth, our brain disproportionately small in relation to its adult size and open to cultural sculpting at multiple levels. Recognizing this, the new field of neuroanthropology places the brain at the center of discussions about human nature and culture. Anthropology offers brain science more robust accounts of enculturation to explain observable difference in brain function; neuroscience offers anthropology evidence of neuroplasticity's role in social and cultural dynamics. This book provides a foundational text for neuroanthropology, offering basic concepts and case studies at the intersection of brain and culture. After an overview of the field and background information on recent research in biology, a series of case studies demonstrate neuroanthropology in practice. Contributors first focus on capabilities and skills—including memory in medical practice, skill acquisition in martial arts, and the role of humor in coping with breast cancer treatment and recovery—then report on problems and pathologies that range from post-traumatic stress disorder among veterans to smoking as a part of college social life. Contributors Mauro C. Balieiro, Kathryn Bouskill, Rachel S. Brezis, Benjamin Campbell, Greg Downey, José Ernesto dos Santos, William W. Dressler, Erin P. Finley, Agustín Fuentes, M. Cameron Hay, Daniel H. Lende, Katherine C. MacKinnon, Katja Pettinen, Peter G. Stromberg
