The Lightning Discharge
by Martin A. UmanIn this readable, absorbing, up-to-date monograph, one of the nation's foremost experts on lightning sets forth most of what has been learned about the subject. To make the material more easily understandable, the author has organized the chapters primarily by lightning process. Following a general introduction and chapters on lightning phenomenology and cloud and lightning charges, he looks into the types and stages of lightning, with chapters on the stepped leader, the attachment process, the return stroke, the dart leader, continuing current, J- and K-processes in discharges to the ground, positive lightning, upward lightning and the artificial initiation of lightning, and cloud discharges. In the final two chapters, Dr. Uman investigates lightning on other planets and examines the phenomenon of thunder.Each chapter contains a reference list, and the book as a whole is augmented with a generous selection of diagrams, charts, and photographs. Appendices on electromagnetics, statistics, and experimental techniques help to clarify some of the concepts covered in the text. A fourth appendix lists relevant books. Of special interest to physicists, meteorologists, and electrical engineers, the newly corrected edition of this detailed study offers a deep understanding of one of nature's most intriguing phenomena. 144 illustrations. Appendices. Index.
The Lightning Rod as a Danger
by Jan MeppelinkThis book investigates the physical effects of a lightning flash on a person near the down conductor of a lightning protection system. These effects are the touch voltage, the step voltage and the side flash. For this purpose, a full-scale simulation model of the human body with a resistance of 1000 ohms was first created. In the simulation model, the body can touch the down conductor or be placed close to it. Furthermore, the specific resistance of the earth is varied. Likewise, insulating layers such as asphalt can be incorporated into the simulation model. Also, special cases like water permeable layers or water layers on an asphalt layer can be calculated. In post-processing, all relevant values can be determined, such as the energy converted in the body, the charge, the current and the voltage applied to the body. A comparison with the permissible limit values then shows for the lightning protection classes whether there is danger or not and provides information on necessary measures. There is a risk for death and injury if the down conductor is touched. However, there is also a risk of a side flash if a person is standing next to a discharge. Site isolation with dry asphalt is effective, but there is a residual risk of surface discharges. In real situations with wet asphalt, water-permeable layers or asphalt with a water layer, however, there is a great risk of death or injury. Equipotential bonding with an earthing grid is a necessary but not sufficient solution with regard to the induced voltage at negative subsequent stroke. Therefore, the situation must always be examined on a case-by-case basis with regard to the safety requirements. The only effective measure to prevent injury and death due to touch voltage is an insulating down conductor in conjunction with equipotential bonding. The measures for reducing the touch voltage, such as site insulation and equipotential bonding, basically also apply to limiting the step voltage. A risk calculation according to IEC 62305-2 gives the mean time between two events of injury and death MG = 1/RA. The tolerable risk is: RA = 0,0001 or MT = 10.000 years, equivalent to one death in 10.000 years.
The Lightning Thread: Fishological Moments and The Pursuit of Paradise
by David ProfumoFrom award winning novelist and journalist David Profumo comes a dazzling work about the restorative power of nature and finding joy in simple pleasures. The Lightning Thread takes the reader on a journey of unexpected delight, personal pleasure and profound discovery. From angling with his father on a spating burn at the height of the Profumo Affair to knocking back mojitos while hunting for Permit, &‘the Robocop of the sea&’, off the coast of Cuba. Much more than just another book about fishing, The Lightning Thread is an exploration of joy and a celebration of simple pleasures in a too complicated world. The significance of angling, as David writes about it, far transcends the mere catching of fish. It is about the extraordinary places he has visited, the remarkable people he has met and the great happiness pursuing his life&’s passion has brought him. Written with warmth, wit and lightly worn erudition, his references range from Ted Hughes to Wittgenstein, from W.C. Fields to Milton, and always hovering in the background is the spectre of Isaak Walton&’s TheCompleat Angler, the Ur-text of halieutic literature. A work of the passionate eclecticism, deep intelligence and virtuosically exuberant prose from one of our finest writers, The Lightning Thread is a future classic and the culmination of lifetime's obsession.

The Lignin Macromolecule: A Compendium of Sustainable Technologies (SpringerBriefs in Applied Sciences and Technology)
by Silvio Vaz Jr.This book covers lignin, a renewable source of carbonaceous material derived from biomass, which is a subject of research, development and innovation in both academia and industry. From lignin we can obtain chemicals (e.g., aromatics, phenols), materials (e.g., fibres, engineered plastics, modified polymers), specialties (e.g., additives as antioxidant), among other products in diverse levels of technology readiness. However, there are challenges to overcome in terms of chemical structure, industrial yields of conversion processes, and the quality of raw material in order to reach the best uses and applications according to the sustainability vision for products and processes. This book deals with the main biochemical pathways of synthesis; advanced analytical techniques; extraction strategies; chemical, biochemical, biological, and physical processing for chemicals and materials; circularity and sustainability aspects for actual and future production chains, allied to life cycle assessment and industrial ecology.
The Limits of Control: Experiments in Mediation and Virulence
by Ryan DiduckRyan Diduck turns his attention to control societies and their protocols in the wake of the global COVID-19 pandemic. What are the political implications of government measures to combat Coronavirus?The end of the world as we know it is no longer imaginary.Severe acute respiratory syndrome Coronavirus 2 (also known as SARS-CoV-2 or COVID-19) is a potent virus that is upturning nearly every aspect of life on earth. But the novel Coronavirus is more than just a virus. It is a marketplace and media event, too, broadcasting at speed, oscillating against the transmission of its mediations. Ultimately, COVID-19 is the pretext upon which nations around the world have enacted social controls of varying severity, strictly limiting the communication, movement, and daily activities of billions of people. This could be a moment of overwhelming consolidation of capital. Or it could further reveal the cracks in a system which has exacerbated the coronavirus pandemic. We are rapidly approaching the limits of control. In the tradition of William S. Burroughs, Naomi Klein, Mark Fisher, and other key theorists of discipline and jurisdiction, The Limits of Control offers a timely new analysis of control societies, and a sibylline roadmap for living together in a hypervirulent world. What we imagine from now on has never mattered more.
The Limits of Genius: The Surprising Stupidity of the World's Greatest Minds
by Katie SpaldingA hilarious look at how the line between 'genius' and 'extremely lucky idiot' is finer than we'd like to admit.The more you delve into the stories behind history's greatest names, the more you realise they have something in common: a mystifying lack of common sense. Take Marie Curie, famous for both discovering radioactivity and having absolutely zero lab safety protocols. Or Lord Byron, who literally took a bear with him to university. Or James Glaisher, a hot-air balloon pioneer who nearly ended up as the world's first human satellite...From Nikola Tesla falling in love with a pigeon to non-swimmer Albert Einstein's near-fatal love of sailing holidays, The Limits of Genius is filled with examples of the so-called brightest and best of humanity doing, to put it bluntly, some really dumb shit. These are the stories that deserve to be told but never are: the hilarious, regrettable and downright baffling lesser-known achievements of the men and women who somehow managed to bungle their way into our history books.(P) 2023 Headline Publishing Group Ltd

The Limits of Matter: Chemistry, Mining, and Enlightenment
by Hjalmar ForsBy studying the chemists at the Swedish Bureau of Mines and their networks, and integrating their practices into the wider European context, the author illustrates how they and their successors played a significant role in the development of our modern notion of matter and made a significant contribution to the modern European view of reality.
The Limits of Organic Life in Planetary Systems
by National Research Council of the National AcademiesThe search for life in the solar system and beyond has to date been governed by a model based on what we know about life on Earth (terran life). Most of NASA's mission planning is focused on locations where liquid water is possible and emphasizes searches for structures that resemble cells in terran organisms. It is possible, however, that life exists that is based on chemical reactions that do not involve carbon compounds, that occurs in solvents other than water, or that involves oxidation-reduction reactions without oxygen gas. To assist NASA incorporate this possibility in its efforts to search for life, the NRC was asked to carry out a study to evaluate whether nonstandard biochemistry might support life in solar system and conceivable extrasolar environments, and to define areas to guide research in this area. This book presents an exploration of a limited set of hypothetical chemistries of life, a review of current knowledge concerning key questions or hypotheses about nonterran life, and suggestions for future research.
The Limits of Resolution (Series in Optics and Optoelectronics)
by Geoffrey de Villiers E. Roy Pike"This beautiful book can be read as a novel presenting carefully our quest to get more and more information from our observations and measurements. Its authors are particularly good at relating it." --Pierre C. Sabatier "This is a unique text - a labor of love pulling together for the first time the remarkably large array of mathematical and statistical techniques used for analysis of resolution in many systems of importance today – optical, acoustical, radar, etc…. I believe it will find widespread use and value." --Dr. Robert G.W. Brown, Chief Executive Officer, American Institute of Physics "The mix of physics and mathematics is a unique feature of this book which can be basic not only for PhD students but also for researchers in the area of computational imaging." --Mario Bertero, Professor, University of Geneva "a tour-de-force covering aspects of history, mathematical theory and practical applications. The authors provide a penetrating insight into the often confused topic of resolution and in doing offer a unifying approach to the subject that is applicable not only to traditional optical systems but also modern day, computer-based systems such as radar and RF communications." --Prof. Ian Proudler, Loughborough University "a ‘must have’ for anyone interested in imaging and the spatial resolution of images. This book provides detailed and very readable account of resolution in imaging and organizes the recent history of the subject in excellent fashion.… I strongly recommend it." --Michael A. Fiddy, Professor, University of North Carolina at Charlotte This book brings together the concept of resolution, which limits what we can determine about our physical world, with the theory of linear inverse problems, emphasizing practical applications. The book focuses on methods for solving illposed problems that do not have unique stable solutions. After introducing basic concepts, the contents address problems with "continuous" data in detail before turning to cases of discrete data sets. As one of the unifying principles of the text, the authors explain how non-uniqueness is a feature of measurement problems in science where precision and resolution is essentially always limited by some kind of noise.
The Limits of Technology and the End of History: Marx and Beyond
by Yefim KatsThis book examines the long-standing belief in infinite scientific and technological progress and links it to the Enlightenment ideal of man as a universal being and subject of the universal world history, destined to become a 'master and possessor of nature.' The author analyzes a broad range of issues in epistemology, the philosophy of history, and the philosophy of science and technology. Marx’s philosophy is explored to the extent that his dialectic of labor sheds light on Western technological optimism and the ideal of human universality and offers an elaborate framework for analyzing the intrinsic limits to technological progress. The focus is on his ‘early’ works, providing a theoretical and humanistic underbelly for the ‘mature’ ideas of the Capital. Examining the epistemic foundations of the belief in infinite progress, the author argues that actual infinity, either in the form of unbounded technological/scientific expansion or infinite complexity of nature, is redundant for the universality of man, his scientific pursuit and historical experience. The conundrum of universality and power calls for a systematic critique of instrumental reason, its practical applicability and value structure.
The Limits to Growth Revisited
by Ugo Bardi"The Limits to Growth" (Meadows, 1972) generated unprecedented controversy with its predictions of the eventual collapse of the world's economies. First hailed as a great advance in science, "The Limits to Growth" was subsequently rejected and demonized. However, with many national economies now at risk and global peak oil apparently a reality, the methods, scenarios, and predictions of "The Limits to Growth" are in great need of reappraisal. In The Limits to Growth Revisited, Ugo Bardi examines both the science and the polemics surrounding this work, and in particular the reactions of economists that marginalized its methods and conclusions for more than 30 years. "The Limits to Growth" was a milestone in attempts to model the future of our society, and it is vital today for both scientists and policy makers to understand its scientific basis, current relevance, and the social and political mechanisms that led to its rejection. Bardi also addresses the all-important question of whether the methods and approaches of "The Limits to Growth" can contribute to an understanding of what happened to the global economy in the Great Recession and where we are headed from there.

The Link: Uncovering Our Earliest Ancestor
by Colin Tudge Josh YoungFor more than a century, scientists have raced to unravel the human family tree and have grappled with its complications. Now, with an astonishing new discovery, everything we thought we knew about primate origins could change. Lying inside a high-security vault, deep within the heart of one of the world's leading natural history museums, is the scientific find of a lifetime--a perfectly fossilized early primate, older than the previously most famous primate fossil, Lucy, by an astonishing forty-four million years. A secret until now, the fossil--"Ida" to the researchers who have painstakingly verified her provenance--is the most complete primate fossil ever found. Forty-seven million years old, Ida rewrites what we've assumed about the earliest primate origins. Her completeness is unparalleled--so much of what we understand about evolution comes from partial fossils and even single bones, but Ida's fossilization offers much more than that, from a haunting "skin shadow" to her stomach contents. And, remarkably, knowledge of her discovery and existence almost never saw the light of day. With exclusive access to the first scientists to study her, the award-winning science writer Colin Tudge tells the history of Ida and her place in the world. A magnificent, cutting-edge scientific detective story followed her discovery, and The Link offers a wide-ranging investigation into Ida and our earliest origins. At the same time, it opens a stunningly evocative window into our past and changes what we know about primate evolution and, ultimately, our own.

The Liquid Crystal Display Story
by Naoyuki KoideThis book focuses on the development of liquid crystal displays (LCDs) and liquid crystal materials (LCs) in Japan. The Committee of Organic Materials Research for Information Sciences of the Japan Society for the Promotion of Science (JSPS) planned the book to document essential LCD innovations and developments since the beginnings of the field-effect LCD technology in 1970. The book illustrates the remarkable effort and progress behind those flat, lightweight, and high-information-content LCDs that have become the indispensable human-machine interface for virtually all electronic devices. In contrast to other publications on this topic, the book illustrates the interdisciplinary character of the LCD technology and its crucial importance for technological progress of the field far beyond displays. It also gives insights into breakthrough innovations not revealed in other publications. Moreover, prospects for the development of LC research toward new fields of applications are provided. In line with its interdisciplinary character, the book targets researchers in basic science as well as engineers and researchers in industry.
The Liquid Metal Fast Breeder Reactor: An Environmental and Economic Critique (Routledge Revivals)
by Thomas B. CochranIn this book, Thomas B. Cochran takes a critical look at the economic and environmental arguments which have been made in favour of an early introduction of the liquid metal fast breeder reactor (LMFBR) as a central component of the United States electrical energy system. First published in 1974, Cochran presents LMFBR as having no environmental advantage over light water reactors and the high temperature gas reactor and seriously questions the economic advantages. This title should be a useful for students interested in environment and sustainability studies, and it is a valuable resource for discussions of future energy strategy.
