Metals in Cells

by Valeria Culotta

Over the last three decades a lot of research on the role of metals in biochemistry and medicine has been done. As a result many structures of biomolecules with metals have been characterized and medicinal chemistry studied the effects of metal containing drugs.This new book (from the EIBC Book Series) covers recent advances made by top researchers in the field of metals in cells [the "metallome"] and include: regulated metal ion uptake and trafficking, sensing of metals within cells and across tissues, and identification of the vast cellular factors designed to orchestrate assembly of metal cofactor sites while minimizing toxic side reactions of metals. In addition, it features aspects of metals in disease, including the role of metals in neuro-degeneration, liver disease, and inflammation, as a way to highlight the detrimental effects of mishandling of metal trafficking and response to "foreign" metals. With the breadth of our recently acquired understanding of metals in cells, a book that features key aspects of cellular handling of inorganic elements is both timely and important. At this point in our understanding, it is worthwhile to step back and take an expansive view of how far our understanding has come, while also highlighting how much we still do not know.The content from this book will publish online, as part of EIBC in December 2013, find out more about the Encyclopedia of Inorganic and Bioinorganic Chemistry, the essential online resource for researchers and students working in all areas of inorganic and bioinorganic chemistry.

Metamaterials and Wave Control

by Eric Lheurette

Since the concept was first proposed at the end of the 20th Century, metamaterials have been the subject of much research and discussion throughout the wave community. More than 10 years later, the number of related published articles is increasing significantly. On the one hand, this success can be attributed to dreams of new physical objects which are the consequences of the singular properties of metamaterials. Among them, we can consider the examples of perfect lensing and invisibility cloaking. On other hand, metamaterials also provide new tools for the design of well-known wave functions such as antennas for electromagnetic waves. The goal of this book is to propose an overview of the concept of metamaterials as a perspective on a new practical tool for wave study and engineering. This includes both the electromagnetic spectrum, from microwave to optics, and the field of acoustic waves. Contents 1. Overview of Microwave and Optical Metamaterial Technologies, Didier Lippens. 2.

The next three chapters cover homogeneous metamaterials (super crystals), random metamaterials (super noncrystals), and inhomogeneous metamaterials (super quasicrystals). The final four chapters examine gradient-index inhomogeneous metamaterials, nearly isotropic inhomogeneous metamaterials, and anisotropic inhomogeneous metamaterials, after which the authors provide their conclusions and closing remarks. The book is completely self-contained, making it easy to follow.

Metametaphysics and the Sciences: Historical and Philosophical Perspectives (Routledge Studies in Metaphysics)

by Frode Kjosavik Camilla Serck-Hanssen

This collection addresses metaphysical issues at the intersection between philosophy and science. A unique feature is the way in which it is guided both by history of philosophy, by interaction between philosophy and science, and by methodological awareness. In asking how metaphysics is possible in an age of science, the contributors draw on philosophical tools provided by three great thinkers who were fully conversant with and actively engaged with the sciences of their day: Kant, Husserl, and Frege. Part I sets out frameworks for scientifically informed metaphysics in accordance with the meta-metaphysics outlined by these three self-reflective philosophers. Part II explores the domain for co-existent metaphysics and science. Constraints on ambitious critical metaphysics are laid down in close consideration of logic, meta-theory, and specific conditions for science. Part III exemplifies the role of language and science in contemporary metaphysics. Quine’s pursuit of truth is analysed; Cantor’s absolute infinitude is reconstrued in modal terms; and sense is made of Weyl’s take on the relationship between mathematics and empirical aspects of physics. With chapters by leading scholars, Metametaphysics and the Sciences is an in-depth resource for researchers and advanced students working within metaphysics, philosophy of science, and the history of philosophy.

Metaphors We Live By

by George Lakoff Mark Johnson

The now-classic Metaphors We Live By changed our understanding of metaphor and its role in language and the mind. Metaphor, the authors explain, is a fundamental mechanism of mind, one that allows us to use what we know about our physical and social experience to provide understanding of countless other subjects. Because such metaphors structure our most basic understandings of our experience, they are "metaphors we live by"—metaphors that can shape our perceptions and actions without our ever noticing them. In this updated edition of Lakoff and Johnson's influential book, the authors supply an afterword surveying how their theory of metaphor has developed within the cognitive sciences to become central to the contemporary understanding of how we think and how we express our thoughts in language.

Metaphors and Analogies in Sciences and Humanities: Words and Worlds (Synthese Library #453)

by A. C. Grayling Shyam Wuppuluri

In this highly-interdisciplinary volume, we systematically study the role of metaphors and analogies in (mis)shaping our understanding of the world. Metaphors and Analogies occupy a prominent place in scientific discourses, as they do in literature, humanities and at the very level of our thinking itself. But when misused they can lead us astray, blinding our understanding inexorably. How can metaphors aid us in our understanding of the world? What role do they play in our scientific discourses and in humanities? How do they help us understand and skillfully deal with our complex socio-political scenarios? Where is the dividing line between their use and abuse? Join us as we explore some of these questions in this volume.

Metaphors for Change: Partnerships, Tools and Civic Action for Sustainability

by David Gee Penny Allen Christophe Bonazzi

How can we get from where we are to where we want to be? Metaphors for Change attempts to answer this question and provide a roadmap for sustainability by bringing together the thoughts of a unique collection of leading change agents from business, government and academia. Environmental questions have previously been dealt with metaphorically, by catastrophism or manicheism (zero growth; Malthusianism, Deep Ecology; "man is the enemy"; less is more). These metaphors have had limited impact because they have failed to connect with the mainstream of cultural, political, and business ideas. This book examines a number of new metaphors – and related partnerships, tools and action – which appear to have greater possibilities for the world in which we now live. The editors argue that Metaphors for Change can deliver to the public and to decision-makers new perceptions ("structured knowledge") that can help interpret the past and the present, and help us forge the future. The wider the gap between the "now" and the "necessary", the stronger the bridging perceptions have to be in order to break through barriers of fear and conservatism. Some of the concepts considered are: sustainable development; the polluter pays principle; the precautionary principle; eco-efficiency; eco-effectiveness; life-cycle assessment; design for the environment; eco-services; dematerialization; industrial symbiosis; industrial ecology; and zero emissions. There are of course other useful metaphors on the horizon, some of them included in this book. Including key contributions from the ground-breaking conferences ECO 97 and ECO 99, along with other specially commissioned and reprinted pieces, Metaphors for Change provides a treasure chest of new ideas, innovations and action. Accessible and forward-thinking, it will prove indispensable both as a student learning tool and as a panoramic overview of the sustainability metaphors key thinkers believe we should be putting into practice.

Metaphors for Environmental Sustainability: Redefining Our Relationship with Nature

by Brendon Larson

Scientists turn to metaphors to formulate and explain scientific concepts, but an ill-considered metaphor can lead to social misunderstandings and counterproductive policies, Brendon Larson observes in this stimulating book. He explores how metaphors can entangle scientific facts with social values and warns that, particularly in the environmental realm, incautious metaphors can reinforce prevailing values that are inconsistent with desirable sustainability outcomes. Metaphors for Environmental Sustainabilitydraws on four case studies--two from nineteenth-century evolutionary science, and two from contemporary biodiversity science--to reveal how metaphors may shape the possibility of sustainability. Arguing that scientists must assume greater responsibility for their metaphors, and that the rest of us must become more critically aware of them, the author urges more critical reflection on the social dimensions and implications of metaphors while offering practical suggestions for choosing among alternative scientific metaphors.

Metaphors of Ed Tech (Issues in Distance Education)

by Martin Weller

The criticisms leveled at online education during the Covid-19 pandemic revealed not only a lack of understanding about how educational technology can be deployed effectively, but a lack of imagination. In this refreshing and insightful volume, Martin Weller provides new ways of thinking about educational technology through a wide range of metaphors. By using metaphors as a mental model, Weller enables educators to move beyond pragmatic concerns into more imaginative and playful uses of technology and to critically examine the appropriate implementation and adoption of ed tech.

Metaphysical Experiments: Physics and the Invention of the Universe (Posthumanities #49)

by Bjørn Ekeberg

An engaging critique of the science and metaphysics behind our understanding of the universe The James Webb Space Telescope, when launched in 2021, will be the premier orbital observatory, capable of studying every phase of the history of the universe, from the afterglow of the Big Bang to the formation of our solar system. Examining the theoretical basis for key experiments that have made this latest venture in astrophysics possible, Bjørn Ekeberg reveals that scientific cosmology actually operates in a twilight zone between the physical and metaphysical. Metaphysical Experiments explains how our current framework for understanding the universe, the Big Bang theory, is more determined by a deep faith in mathematical universality than empirical observation. Ekeberg draws on philosophical insights by Spinoza, Bergson, Heidegger, and Arendt; on the critical perspectives of Latour, Stengers, and Serres; and on cutting-edge physics research at the Large Hadron Collider, to show how the universe of modern physics was invented to reconcile a Christian metaphysical premise with a claim to the theoretical unification of nature.By focusing on the nonmathematical assumptions underlying some of the most significant events in modern science, Metaphysical Experiments offers a critical history of contemporary physics that demystifies such concepts as the universe, particles, singularity, gravity, blackbody radiation, the speed of light, wave/particle duality, natural constants, black holes, dark matter, and dark energy. Ekeberg&’s incisive reading of the metaphysical underpinnings of scientific cosmology offers an innovative account of how we understand our place in the universe.

Metapopulations and Wildlife Conservation

by Dale Richard Mccullough Jonathan Ballou Glen Woolfenden Bradley Stith F. Lance Craighead Bill Pranty

Development of rural landscapes is converting once-vast expanses of open space into pockets of habitat where wildlife populations exist in isolation from other members of their species. The central concept of metapopulation dynamics -- that a constellation of partially isolated patches can yield overall stability to a system that is chaotic at the level of the individual patch -- offers an important new way of thinking about the conservation and management of populations dispersed among small habitat fragments. This approach is proving to be a rich resource for biologists hoping to arrest the current catastrophic loss of biodiversity.This volume provides a comprehensive overview of the subject, addressing the needs of an applied professional audience for comprehensible information to integrate into their practices. Leading conservation biologists, ecologists, wildlife managers, and other experts consider the emergence and development of metapopulation theory and explore its applicability and usefulness to real-world conservation programs. Conservation is essential reading for anyone working in the field of wildlife conservation and management.
