"This book guides readers, step-by-step, through the author's revolutionary wax-up technique to recreate the complex morphology of premolar and molar teeth. ...illustrated throughout, each chapter builds technical knowledge with chapters on nomenclature, morphology, wax handling and application, functional wax-up sequences for maxillary and mandibular dentition, and adhesive cementation and culminates in a series of ...clinical cases. A ...resource for any dental technician wanting to review occlusal form and improve the functional morphology of posterior restorations." -- Publisher.
Stem cell research, genetically modified crops, animals developed with personalized human organs for transplantation, and other previously inconceivable biotech applications could increase the quality of all human lives and maximize the health of the biosphere. But ironically, as the science becomes more precise and transparent, it also becomes more contentious. In Challenging Nature, Silver argues that although they seem to have little in common, Christian fundamentalists opposed to embryo research and New Age organic food devotees are both driven by a deeply rooted fear that biotechnology—in some guise—challenges the sovereignty of a higher or deeper transcendent authority. In the short term, Silver writes, Eastern spiritual traditions will give Asian countries a research advantage. But over the millennia, human nature may have the potential to remake Mother Nature in the image of an idealized world.
Contemporary ideas of nature were largely shaped by schools of thought from Western cultural history and philosophy until the present-day concerns with environmental change and biodiversity conservation. There are many different ways of conceptualising nature in epistemological terms, reflecting the tensions between the polarities of humans as masters or protectors of nature and as part of or outside of nature. The book shows how nature is today the focus of numerous debates, calling for an approach which goes beyond the merely technical or scientific. It adopts a threefold – critical, historical and cross-disciplinary – approach in order to summarise the current state of knowledge. It includes contributions informed by the humanities (especially history, literature and philosophy) and social sciences, concerned with the production and circulation of knowledge about "nature" across disciplines and across national and cultural spaces. The volume also demonstrates the ongoing reconfiguration of subject disciplines, as seen in the recent emergence of new interdisciplinary approaches and the popularity of the prefix "eco-" (e.g. ecocriticism, ecospirituality, ecosophy and ecofeminism, as well as subdivisions of ecology, including urban ecology, industrial ecology and ecosystem services). Each chapter provides a concise overview of its topic which will serve as a helpful introduction to students and a source of easy reference. This text is also valuable reading for researchers interested in philosophy, sociology, anthropology, geography, ecology, politics and all their respective environmentalist strands.
Abiotic stressors, such as drought, extreme temperatures, heavy metals, or high salinity, are causing huge crop losses worldwide. These abiotic stressors are expected to become more extreme, less predictable, and more widespread in the near future. The harm of abiotic stresses includes the disruption of cellular redox homeostasis, reactive oxygen species (ROS) production, and oxidative stress in the plant. Plants have different mechanisms to fight stress, and these mechanisms are responsible for maintaining the required homeostasis in plants. Research on gasotransmitters is rapidly expanding and knowledge regarding the potential of gasotransmitters in biology and medicine is accumulating. Over the past few decades, the roles of these signaling molecules, especially NO and H2S, have been extensively studied for their application in plants. Recently, the emissions of endogenous gasotransmitters in plants have been widely studied and analyzed, thereby providing information to facilitate our understanding of new gasotransmitters signaling pathways. Given the multidimensional role of these signaling molecules, research over the past decades in mitigating abiotic stresses in plant biology and from an agriculture point of view, we intend to bring forth a comprehensive volume “Gasotransmitters Signaling in Plants under Challenging Environment". We are hopeful that this comprehensive volume will furnish the requisite of all those who are working or have an interest in the proposed topic
Neuroscience has made phenomenal advances over the past 50 years and the pace of discovery continues to accelerate. On June 25, 2008, the Institute of Medicine (IOM) Forum on Neuroscience and Nervous System Disorders hosted more than 70 of the leading neuroscientists in the world, for a workshop titled "From Molecules to Minds: Challenges for the 21st Century." The objective of the workshop was to explore a set of common goals or "Grand Challenges" posed by participants that could inspire and rally both the scientific community and the public to consider the possibilities for neuroscience in the 21st century. The progress of the past in combination with new tools and techniques, such as neuroimaging and molecular biology, has positioned neuroscience on the cusp of even greater transformational progress in our understanding of the brain and how its inner workings result in mental activity. This workshop summary highlights the important issues and challenges facing the field of neuroscience as presented to those in attendance at the workshop, as well as the subsequent discussion that resulted. As a result, three overarching Grand Challenges emerged: How does the brain work and produce mental activity? How does physical activity in the brain give rise to thought, emotion, and behavior? How does the interplay of biology and experience shape our brains and make us who we are today? How do we keep our brains healthy? How do we protect, restore, or enhance the functioning of our brains as we age?
Throughout history, climate change has been an important driving force behind human behaviour. This archaeological study seeks to understand the complex interrelations between that behaviour and climatic fluctuations, focussing on how climate affected the social relations between neighbouring communities of occasionally differing nature. It is argued that developments in these relations will fall within a continuum between competition on one end and cooperation on the other. The adoption of a particular strategy depends on whether that strategy is advantageous to a community in terms of the maintenance of its well-being when faced with adverse climate change. This model will be applied to northern Mesopotamia between 3000 and 1600 BC. Local palaeoclimate proxy records demonstrate that aridity increased significantly during this period. Within this geographical, chronological, and climatic framework, this study looks at changes in settlement patterns as an indication of competition among sedentary agriculturalist communities, and the development of the Amorite ethnic identity as reflecting cooperation among sedentary and more mobile pastoralist communities.
Crossing disciplinary boundaries, this volume by Özerdem and Roberts conceptualizes the challenges of developing sustainable agriculture in post-conflict environments as well as identifying the policies and practical solutions to achieve sustainable agricultural production which is central to the survival of humanity. Without sustainable agriculture, populations remain vulnerable increasing the likelihood of a return to conflict. Therefore, sustainable agriculture is central to effective post-conflict recovery that provides human security as well as stability and rule of law. Unique in combining a comprehensive and comparative understanding of sustainable agriculture challenges in post-conflict environments, there is originality in the interdisciplinary nature of the book. Interdisciplinary often means bringing together a political scientist and a sociologist, but in this case it means bringing together natural and social scientists, as well as those with practical experience in development and agricultural contexts. By adopting a holistic multi-disciplinary approach which identifies key themes and case studies, this book sets the scene for the debate surrounding sustainable agriculture in post-conflict environments. Seeing 'fixing' agriculture as more than merely a technical matter, the volume focuses on this critical post-conflict challenge with social, political and cultural characteristics and consequences as well as the obvious economic ones.
Choice pervades our society: it is founded on political rights to choose and our economy on market choices, but we have now reached the point where choice is extended almost everywhere. This lively and topical book provides a critique of choice in contemporary society and policy, arguing that we can have too much of a good thing. And there are alternatives. In part one, the author shows how choice works at a personal level, its demands, and how it can fail. By examining healthcare, education and pensions, he then explores the alternatives, such as provision. In part two the book reviews the impact of choice through the life cycle, in areas such as careers, relationships fertility, retirement and death. The author considers whether this enhances or burdens our lives, and questions the assumption that more choice is always for the better.
Feminist scholars in disciplines ranging from law to geography challenge our traditional notion of a public/private divide in legal and public policy in Canada and internationally
Tim Noakes is one of the world’s leading authorities on the science behind sport and a successful sportsman in his own right. Through a lifetime of research, he has developed key scientific concepts in sport that have not only redefined the way elite athletes and teams approach their professions, but challenged conventional global thinking in these areas. In this new and updated edition of Challenging Beliefs, Noakes shares his views on everything from the myths perpetuated by the sports-drink industry to the prevalence of banned substances, the need to make rugby a safer sport and the benefits of a high-protein, low-carb diet. The teams and athletes with whom Noakes has worked make fascinating backdrops to these topics, highlighting the importance of science in sport in human terms. In providing an intimate look at the golden threads running through Noakes’s life and career, this remarkable book reveals the landmark theories and principles generated by one of the greatest minds in the history of sports science.
