Rethinking the Concept of Waste and Mass Consumption: Preserving Resources through Reuse, Repair and Recycling (Routledge Studies in Sustainability)
by Richard WaiteThis book presents hard facts, drawn from extensive research, to highlight our unsustainable consumption of the Earth’s resources and the limitations of the UK’s current management of waste and recycling.Setting out a bleak picture of a world in which we are literally consuming our planet, the book explores the psychological, economic and capitalist drivers behind this behaviour. Controversially, the book examines the drawbacks of the current approach adopted by many local authorities on the kerbside collection of recyclable materials, as well as the UK governments’ strategic approaches to household recycling, including the lack of UK- wide infrastructures for packaging reuse, and for product repair and recycling. It challenges the whole concept of waste, leading to a proposed new strategy for the management of household waste, including a simplified household collection system, the introduction of an incineration tax and the banning of all household waste exports. The author proposes reconceptualising waste as unwanted but valuable material and argues that the responsibility for facilitating reuse, repair and recycling, rests with manufacturers who must start designing with the end in mind.Given the current economic climate, and a dampening of the green agenda within UK politics, the book provides a much- needed call for critical discourse on how, and how much, we consume and sets out clear, practical solutions for change. The book will be of interest to manufacturers, retailers, consumers, local authorities, policy makers, students and professionals looking to reduce our impact on the environment.
Rethinking the Environmental Impacts of Renewable Energy: Mitigation and management
by Alexander ClarkeRenewable energy is important as a substitute for finite fossil fuels and inflexible nuclear power and could conceivably power the world. However, this is challenging as the world is currently 80% dependent on fossil fuels, and renewable sources produce only about 15% of total energy. Conversion technologies for use with many of the eight different primary sources of renewable energy are only just emerging as viable technologies. While renewable energy sources will not run out, and their use involves little or no release of carbon dioxide or ionising wastes, they do have local environmental impacts of their own. This book analyses the nature of environmental impacts from renewable sources. A novel method of assessing impacts is explored based on a set of parameters centred on how diffuse or concentrated the energy flow is. The approach that is developed will inform engineers, designers, policy makers and planners as well as researchers in the area.
Reti Neurali Solitoniche: Un Innovativo Network Neurale Fotonico Basato su Interconnessioni Solitoniche
by Alessandro BileQuesto libro descrive la realizzazione di un sistema ottico intelligente in grado di replicare gli elementi funzionali del cervello biologico. Partendo da un'analisi delle dinamiche neuronali biologiche, ed effettuando una panoramica sullo stato dell'arte dei sistemi neuromorfi sviluppati fino ad oggi, il cuore del manoscritto descrive delle innovative reti neurali completamente ottiche realizzate attraverso la tecnologia dei solitoni spaziali. Dopo una breve introduzione sulla biologia delle reti neurali (Capitolo 1), il libro si addentra nella descrizione del problema neuromorfo, sottolineando le peculiarità degli hardware ottici sviluppati finora (Capitolo 2). Il Capitolo 3 è dedicato alla descrizione delle psicomemorie, che rappresentano il modello dell'apprendimento umano secondo le teorie della moderna neuropsicologia. Questo capitolo fornisce i prerequisiti per comprendere come le reti neurali solitoniche (SNN) siano in grado di apprendere e come la fisica che le governa si avvicini al funzionamento dei modelli biologici. Il Capitolo 4 descrive nel dettaglio gli esperimenti effettuati per la realizzazione di neuroni ottici solitonici in sottili strati di niobato di litio. Vengono discusse le tecniche ottiche per l'apprendimento supervisionato e non supervisionato. L'intero capitolo è corredato da risultati teorici, simulativi e sperimentali. Inoltre, spiega come un neurone X-Junction sia in grado di stabilire sinapsi, modificarle o cancellarle. La cancellazione di strutture solitoniche rappresenta un'importante innovazione nel campo dell'ottica non lineare. Infine, il Capitolo 5 illustra l'implementazione di una rete di neuroni in grado di elaborare informazioni e memorizzarle esattamente come fa una memoria episodica umana. Il Capitolo si conclude con una serie di approfondimenti sulle linee di ricerca attualmente in corso sulla base dei risultati ottenuti. Il libro è destinato a studenti e ricercatori nei campi dell'ottica, delle applicazioni fotoniche e della biologia. Tuttavia, i principali beneficiari di questo libro sono i ricercatori senior nel campo dell'ottica non lineare e dell'intelligenza artificiale. Per comprendere pienamente i risultati, è importante avere una conoscenza di base della fisica ottica e della biologia dei neuroni.

Retirement On The Line: Age, Work, and Value in an American Factory
by Caitrin LynchIn an era when people live longer and want (or need) to work past the traditional retirement age, the Vita Needle Company of Needham, Massachusetts provides inspiration and important lessons about the value of older workers. Vita Needle is a family-owned factory that was founded in 1932 and makes needles, stainless steel tubing and pipes, and custom fabricated parts. As part of its unusual business model, the company seeks out older workers; the median age of the employees is seventy-four. In Retirement on the Line, Caitrin Lynch explores what this unusual company's commitment to an elderly workforce means for the employer, the workers, the community, and society more generally. Benefiting from nearly five years of fieldwork at Vita Needle, Lynch offers an intimate portrait of the people who work there, a nuanced explanation of the company's hiring practices, and a cogent analysis of how the workers' experiences can inform our understanding of aging and work in the twenty-first century. As an in-depth study of a singular workplace, rooted in the unique insights of an anthropologist who specializes in the world of work, this book provides a sustained focus on values and meanings-with profound consequences for the broader assumptions our society has about aging and employment.
Retooling Manufacturing: Bridging Design, Materials, And Production
by Manufacturing Committee on Bridging DesignAs the Department of Defense continues development of the future warrior system, the difficulty of moving rapidly from design to manufacturing for complex technologies is becoming a major concern. In particular, there are communication gaps between design and manufacturing that hinder rapid development of new products important for these future military developments. To help address those concerns, DOD asked the NRC to develop a framework for “bridging” these gaps through data management, modeling, and simulation. This report presents the results of this study. It provides a framework for virtual design and manufacturing and an assessment of the necessary tools; an analysis of the economic dimensions; an examination of barriers to virtual design and manufacturing in the DOD acquisition process; and a series of recommendations and research needs.

Return to Earth
by Buzz Aldrin Wayne WargaBuzz Aldrin's courageous, inspiring account of fame and depression following Apollo 11 When Buzz Aldrin returned victorious from the Apollo 11 mission as one of the first men to have walked on the moon, he didn't realize that, in other ways, his odyssey had just begun. "There was a jolt as the small drogue chutes opened," Aldrin relates in the opening passages of Return to Earth, remembering his abrupt descent into the gravity of the blue planet. "We landed with all the grace of a freight elevator." And with that atmospheric splash, Aldrin and coauthor Wayne Warga take us on a journey through the human side of the space program as the astronaut learns to cope with the sudden pressures of being a lionized public persona. In honest, stripped-away prose, Aldrin reveals a side of instant fame for which neither West Point nor NASA could have ever prepared him. One minute a fighter pilot and engineer, the next a cultural icon burdened with the adoration of thousands, Aldrin gives a candid account of the depression that resulted from trying to be too many things to too many people, leading the astronaut to later remark, "I traveled to the moon, but the most significant voyage of my life began when I returned from where no man had been before." Speaking openly about the affair that threatened his marriage and the concerns that plagued him upon returning from the historic mission, Aldrin pens a compelling memoir that also serves as an excellent guide for those times in life when power and success conspire to corrupt even the best of us.

Returning People to the Moon After Apollo: Will It Be Another Fifty Years? (Springer Praxis Books)
by Pat NorrisJuly 2019 marks 50 years since Neil Armstrong took his famous first steps on the surface of the Moon. As people around the world celebrate the anniversary of this great American achievement, they might wonder why there have been no further human missions to the Moon since Apollo 17 in 1972. This book assesses the legacy of the Apollo missions based on several decades of space developments since the program’s end. The question of why we haven’t sent humans back to the Moon is explored through a multidisciplinary lens that weaves together technological and historical perspectives. The nine manned Apollo missions, including the six that landed on the Moon, are described here by an author who has 50 years of experience in the space industry and whose work spanned the Apollo 8–13 missions. The final section of the book provides a comprehensive assessment of today’s programs and current plans for sending humans to the Moon.
Reuniting Economy and Ecology in Sustainable Development (Sustainable Community Development Ser. #7)
by Charles R. BeatonReuniting Economy and Ecology in Sustainable Development is part of a series on the various aspects of sustainable development, where "community" focuses on the primacy and quality of relationships among people sharing a particular place and between people and their environment. "Development" means personal and social transformation to a higher level of consciousness and a greater responsibility to be one anothers keepers, and "sustainability" is the act whereby one generation saves options by passing them to the next generation, which saves options by passing them onto the next and so on. The vision put forth in this book is one of melding ecology and economy into a unifying concept of social-environmental sustainability. The author suggests that dividing ecology and economy conceptually will destroy society as we know it. Our task as adults is to repair the environment for the children who must inherit it.The link between economics and ecology and the immense potential of that connection to influence the process of change within communities is the focus of this book. The authors theorize that in a healthy, future-oriented community there is a dominant role for sustainability. Each of these four concepts - economics, ecology, community and sustainability - are intimidating on their own. There has been volumes written on each topic separately but very little written on how they are connected in relation to the environment. Reuniting Economy and Ecology makes those connections and provides a base for finding solutions to achieving sustainable communities.
Reusable Booster System: Review and Assessment
by Assessment Committee for the Reusable Booster System: ReviewOn June 15, 2011, the Air Force Space Command established a new vision, mission, and set of goals to ensure continued U. S. dominance in space and cyberspace mission areas. Subsequently, and in coordination with the Air Force Research Laboratory, the Space and Missile Systems Center, and the 14th and 24th Air Forces, the Air Force Space Command identified four long-term science and technology (S&T) challenges critical to meeting these goals. One of these challenges is to provide full-spectrum launch capability at dramatically lower cost, and a reusable booster system (RBS) has been proposed as an approach to meet this challenge. The Air Force Space Command asked the Aeronautics and Space Engineering Board of the National Research Council to conduct an independent review and assessment of the RBS concept prior to considering a continuation of RBS-related activities within the Air Force Research Laboratory portfolio and before initiating a more extensive RBS development program. The committee for the Reusable Booster System: Review and Assessment was formed in response to that request and charged with reviewing and assessing the criteria and assumptions used in the current RBS plans, the cost model methodologies used to fame [frame?] the RBS business case, and the technical maturity and development plans of key elements critical to RBS implementation. The committee consisted of experts not connected with current RBS activities who have significant expertise in launch vehicle design and operation, research and technology development and implementation, space system operations, and cost analysis. The committee solicited and received input on the Air Force launch requirements, the baseline RBS concept, cost models and assessment, and technology readiness. The committee also received input from industry associated with RBS concept, industry independent of the RBS concept, and propulsion system providers which is summarized in Reusable Booster System: Review and Assessment.
Reuse and Recycling of Lithium-Ion Power Batteries
by Guangjin ZhaoA comprehensive guide to the reuse and recycling of lithium-ion power batteries—fundamental concepts, relevant technologies, and business models Reuse and Recycling of Lithium-Ion Power Batteries explores ways in which retired lithium ion batteries (LIBs) can create long-term, stable profits within a well-designed business operation. Based on a large volume of experimental data collected in the author’s lab, it demonstrates how LIBs reuse can effectively cut the cost of Electric Vehicles (EVs) by extending the service lifetime of the batteries. In addition to the cost benefits, Dr. Guangjin Zhao discusses how recycling and reuse can significantly reduce environmental and safety hazards, thus complying with the core principles of environment protection: recycle, reuse and reduce. Offering coverage of both the fundamental theory and applied technologies involved in LIB reuse and recycling, the book's contents are based on the simulated and experimental results of a hybrid micro-grid demonstration project and recycling system. In the opening section on battery reuse, Dr. Zhao introduces key concepts, including battery dismantling, sorting, second life prediction, re-packing, system integration and relevant technologies. He then builds on that foundation to explore advanced topics, such as resource recovery, harmless treatment, secondary pollution control, and zero emissions technologies. Reuse and Recycling of Lithium-Ion Power Batteries: • Provides timely, in-depth coverage of both the reuse and recycling aspects of lithium-ion batteries • Is based on extensive simulation and experimental research performed by the author, as well as an extensive review of the current literature on the subject • Discusses the full range of critical issues, from battery dismantling and sorting to secondary pollution control and zero emissions technologies • Includes business models and strategies for secondary use and recycling of power lithium-ion batteries Reuse and Recycling of Lithium-Ion Power Batteries is an indispensable resource for researchers, engineers, and business professionals who work in industries involved in energy storage systems and battery recycling, especially with the manufacture and use (and reuse) of lithium-ion batteries. It is also a valuable supplementary text for advanced undergraduates and postgraduate students studying energy storage, battery recycling, and battery management.
Reuse of Materials and Byproducts in Construction
by Alan RichardsonThe construction industry is the largest single waste producing industry in the UK. Ensuring a supply chain of recycled materials affords many potential gains, achieved through: reducing the material volume transported to already over-burdened landfill sites, possible cost reductions to the contractor/client when considering the landfill tax saved and the potential for lower cost material replacements, a reduction in the environmental impact of quarrying and the saving of depleting natural material resources. Reuse of Materials and Byproducts in Construction: Waste Minimization and Recycling addresses use of waste and by products in the construction industry. An over view of new "green" design guides to encourage best practice will be examined and current legislation that channels on site practices, such as site waste management plans. Fundamental individual construction materials are discussed and the process of reforming by products and waste products into new construction materials is investigated, examining the material performance, energy required to convert waste into new products and viability of recycling. The main range of constructional materials will be examined. Aimed at postgraduate students, lecturers and researchers in construction and civil engineering, the book will also be of interest to professional design practices.

This unique book outlines approaches to sharing and reusing resources for e-learning. Drawing upon research by 30 prominent scholars from seven countries, the authors offer multiple perspectives from school, continuing and higher education as well as industry. It is essential reading for those implementing e-learning in education and corporate training, including teachers, trainers, academics, educational developers and support staff as well as senior managers.
Reusing Open Resources: Learning in Open Networks for Work, Life and Education (Advancing Technology Enhanced Learning)
by Allison Littlejohn Chris PeglerEvery day, learners use and reuse open, digital resources for learning. Reusing Open Resources offers a vision of the potential of these open, online resources to support learning. The book follows on from Reusing Online Resources: A Sustainable Approach to E-learning. At that time focus was on the creation, release and reuse of digital learning resources modeled on educational materials. Since then the open release of resources and data has become mainstream, rather than specialist, changing societal expectations around resource reuse. Social and professional learning networks are now routine places for the exchange of online knowledge resources that are shared, manipulated and reused in new ways, opening opportunities for new models of business, research and learning. The goal of this book is to extend the debate of how open, online resources might support learning across diverse contexts. Twenty-four distinguished experts from nine countries distributed across Europe and North America contribute empirical evidence and ideas. Collectively they provide a vision of the potential of open, online resources to support learning across everyday contexts of education, work and life.

Revealing New Worlds: Three Victorian Women Naturalists
by Suzanne Le-May SheffieldThe story of nineteenth-century science often tells a tale of a masculinized professionalizing domain. Scientific man increasingly pushed women out, marginalized them and constructed them as naturally feminine creatures incapable of intellectual work, particularly scientific work. Yet many women participated in various scientific endeavours throughout the century. This work asks why, when the waters were so inviting, did women dive deeply into the swirling maelstrom of scientific practice, scientific controversies and scientific writing? Victorian women certainly recognised that male naturalists were not always willing to welcome them warmly into their inner sanctum of scientific work honour and prestige. Moreover, they recognised the existence of a more general social stigma that thwarted any woman's participation in intellectual endeavours. However, their fascination with algology, botany and entomology led Margaret Gatty, Marianne North and Eleanor Ormerod to reach beyond acceptable gendered roles, to undertake field work, to paint, write, popularize, experiment and discover. Each exhibited a passion for their chosen field, a need for intellectual, artistic and scientific work, and a desire for scientific recognition and renown. This book examines the ability of women to understand themselves and respond to their needs as complex human beings. Within a framework of socially and scientifically constructed norms, these Victorial women use d science as a path to self-awareness and intellectual accomplishment.
Revealing the Invisible Mine: Social Complexities of an Undeveloped Mining Project (Pacific Perspectives: Studies of the European Society for Oceanists #8)
by Emilia SkrzypekExploring the social complexities of the Frieda River Project in Papua New Guinea, this book tells the story of local stakeholder strategies on the eve of industrial development, told largely from the perspective of the Paiyamo - one of the project’s so-called ‘impact communities’. Engaging ideas of knowledge, belief and personhood, it explains how fifty years of encounters with exploration companies shaped the Paiyamo’s aspirations, made them revisit and re-examine their past, and develop new strategies to move towards a better, more prosperous future.
