Environmental science, engineering and technology Books

Book SynopsisIn the early twentieth century, the first large batch of Chinese civil engineers had graduated from the USA, and together with their American senior colleagues returned to China. They were enthusiastic about reconstructing the young republic by building new railways, highways, and canals, but what the engineers experienced in China, including mismanaged railways, useless highways, and silted canals, did not always meet their expectations and ideals. In this book, Thorben Pelzer makes the stories of these Chinese and American engineers come to life through exploring previously unpublished letters, rare images, maps, and a rich biographical dataset. He argues that the experiences of these engineers include a myriad of contradictions, disillusionment, and discontent, keeping the engineering profession in a constant flux of searching for its meaning and its place in Republican China.Table of ContentsAcknowledgments List of Figures and Tables List of Abbreviations Glossary of Recurring Civil Engineers Note on Transcriptions Introduction  Open Roads in China  1 Historical Background  2 The Segment of US-Trained Civil Engineers  3 “Specialized but Equally Ordinary Men”  4 Engineering and Its Discontents  5 Chapter Overview 1 Nationalism and the Cosmopolitical  Education Overseas, 1905–1918  1 Early Ways Into the United States  2 Engineering Education  3 Engineering Practice  4 The Cosmopolitan Dimension  5 The National Dimension  6 Bringing the Profession Home  7 Conclusion 2 Financial Constraint  The Grand Canal Board, 1918–1922  1 A Transnational Venture  2 Recruiting a Team  3 Surveying an Unstable Environment  4 The Money Goes Astray  5 Solidarity—The Yellow River Bridge Controversy  6 Frustration—Huai River Improvement Schemes  7 Conclusion 3 Political Dependency  Wang Jingchun at the Chinese Eastern Railway, 1919–1924  1 The Nationalist Paradigm  2 The Efficiency Paradigm  3 Wang Jingchun’s Ascend to Power  4 The Chinese Eastern—“A Railroad Born in Sin”  5 The Wang–Ostroumov Dyad  6 The End of Expert Management  7 Conclusion 4 The Visible College  The Early Association of Chinese & American Engineers, 1919–1927  1 Formation and Organizational Makeup  2 Functions of the Association and Its Journal  3 Ethics and Socialization  4 Career Opportunities  5 Network for Collaboration  6 Transnational Friendship  7 Conclusion 5 Cohesion and Exclusion  The Relief Commission Paves the Provinces, 1926–1934  1 “Good Roads” and Labor Relief  2 Contested Authority in Yunnan  3 Guizhou—The Strong State  4 Guizhou—Mass Mobilization  5 Guizhou—Beneficiaries and Burden Bearers  6 Continuities Between Xi’an and Lanzhou  7 Conclusion 6 Demise without Exhaustion  The Withdrawal of US Engineers, 1928–194  1 Early Troubles of the ACAE  2 Support for the Command Economy  3 The Resurrection of the ACAE  4 Crisis of Repute—The Salaqi Irrigation Project  5 The Militarization of Civil Engineering  6 The Plight of US Engineers  7 Conclusion 7 Wartime Engineering  Ling Hongxun under Pressure, 1932–1945  1 A Career Start of Ups and Downs  2 Abortive Western Expansions  3 From Guangzhou to Hankou: Cutting Time  4 Lessons Learnt and Lessons Dealt  5 Drawbacks of the Strong State  6 The Xinjiang–Gansu Railway  7 Conclusion 8 Conclusion  1 Summary  2 Findings  3 Implications  4 Outlook  5 Coda: Loose Ends Bibliography Index

Book SynopsisShallow groundwater systems are important as a source of water, for sustenance of stream baseflow, and for wetland and riparian ecosystems. They are also central to waterlogging, and dryland and irrigation salinity problems. Response time to hydrologic change and pollutant loadings is fast among shallow aquifiers, and it is important that hydrogeologists and natural resource managers understand the unsaturated zone processes which links human activity at the soil surface and the underlying groundwater, and vice versa. This volume of papers explores practical aspects of soil and surface water interactions with groundwater, including modelling of flow and contaminant transport in the unsaturated and saturated zones.

Book Synopsis"This book is a synthesis of contributions drawn from the 12th Nitrogen Workshop held at the University of Exeter, UK. It provides a valuable compilation of current research, aimed at reconciling the environmental and economic components of N cycling within the context of a productive agricultural industry. The book is divided into seven main sections, which examine systematically, the nature of the problems associated with losses of N and a range of possible solutions. Section 1, ‘Drivers towards sustainability-why change?’ identifies the need to adopt new strategies to avoid losses to the environment. Section 2 considers the options for ‘Matching supply with demand’, followed by the reasons for, and means of ‘Controlling losses to air’ and to ‘water’ in section 3 and 4. Section 5 describes the challenges of ‘Reconciling productivity with environmental considerations’. The remaining sections describe some mathematical models to assist the researcher, with the final section devoted to reports from the ‘Themed Working Groups’ which debated the following topical questions: Organic matter: does it matter, or can technology overcome most problems related to soil fertility? Optimising N additions: can we integrate fertilizer use and manure use? Controlling gaseous N emissions: what is achievable? Missing N: is the solution in dissolved N? Pollution problems: mitigation, or are we swapping one form of pollution for another? System studies: do we need them, or can they be replaced by desktop studies? Model answers: can we improve their level of confidence and applicability? This book will be of value to researchers, policy makers and all those wishing to promote more efficient use of N."Table of ContentsPreface 7; Section 1 - Drivers towards sustainability: why change? 27; Drivers towards sustainability: why change? 29; J.J.

Book Synopsis"Because of the growing societal concerns regarding industrial environmental pollution, it is essential to get a deeper understanding of the factors influencing firms to reduce their environmental impact. This book considers these concerns by evaluating the importance of these factors in reference to environmental management in the Dutch food and beverage industry. It develops an integrated research framework building on the inside-out and outside-in perspectives on environmental management. Empirical data were gathered in 2002 and 2005. This book provides interesting insights into the developments in this period showing that the impact of the business environment has extended from the traditionally important stakeholders, such as government and societal groups, to include commercial chain and network actors as well, including buyers and suppliers, but also bank and insurance firms. Furthermore, the analyses demonstrate that public-private voluntary agreements can be an effective policy instrument. Firms with a proactive business strategy appear to pay more attention to environmentally friendly product (re)design, which is crucial to reduce environmental impact from a cradle-to-cradle perspective. This book is of interest to environmental and general management in firms that want to reach environmental excellence. Policy implications are drawn for environmental policy-makers, environmental agencies and environmental interest groups that aim for stimulating firms to clean up."

Book SynopsisThis might be the first book that deals mostly with the 3D technology computer-aided design (TCAD) simulations of major state-of-the-art stress- and strain-engineered advanced semiconductor devices: MOSFETs, BJTs, HBTs, nonclassical MOS devices, finFETs, silicon-germanium hetero-FETs, solar cells, power devices, and memory devices. The book focuses on how to set up 3D TCAD simulation tools, from mask layout to process and device simulation, including design for manufacturing (DFM), and from device modeling to SPICE parameter extraction. The book also offers an innovative and new approach to teaching the fundamentals of semiconductor process and device design using advanced TCAD simulations of various semiconductor structures. The simulation examples chosen are from the most popular devices in use today and provide useful technology and device physics insights. To extend the role of TCAD in today’s advanced technology era, process compact modeling and DFM issues have been included for design–technology interface generation.Unique in approach, this book provides an integrated view of silicon technology and beyond—with emphasis on TCAD simulations. It is the first book to provide a web-based online laboratory for semiconductor device characterization and SPICE parameter extraction. It describes not only the manufacturing practice associated with the technologies used but also the underlying scientific basis for those technologies. Written from an engineering standpoint, this book provides the process design and simulation background needed to understand new and future technology development, process modeling, and design of nanoscale transistors.The book also advances the understanding and knowledge of modern IC design via TCAD, improves the quality in micro- and nanoelectronics R&D, and supports the training of semiconductor specialists. It is intended as a textbook or reference for graduate students in the field of semiconductor fabrication and as a reference for engineers involved in VLSI technology development who have to solve device and process problems. CAD specialists will also find this book useful since it discusses the organization of the simulation system, in addition to presenting many case studies where the user applies TCAD tools in different situations.Table of ContentsIntroduction.
