Lubrication in Practice
by W. L. RobertsonThis book will appeal to a broad range of engineers and managers in all sectors of manufacturing engineering, power generation and transport. Drawing on their specialist experience and knowledge, the many contributors show how the careful application of correct lubrication can lead to improved productivity, longer plant and equipment life and higher profits. Throughout the emphasis is on showing what lubricants can do, and how they can best be used. After introductory chapters that summarise the basic theory and the general types and properties of lubricants, there follow eleven chapters that cover such specific applications as diesel and petrol engines, hydraulics, compressors, machine tools and cutting oils. The last two chapters discuss the storage and handling of lubricants, and lubrication planning. The majority of the authors and editors, have worked for Esso Petroleum Company Limited and have a unique range of experience in this area. Many of the authors have contrbuted to advances in techniques for imrproved lubrication in their specialist areas.
Luc Reychler: A Pioneer in Sustainable Peacebuilding Architecture (Pioneers in Arts, Humanities, Science, Engineering, Practice #24)
by Luc Reychler Arnim LangerThis book provides a unique personal perspective on the field of peace research. It not only highlights Luc Reychler’s significant contributions to the theory and praxis of sustainable peacebuilding, but also offers important reflections on the evolution of peace research as an independent discipline. The central concept of this book – and of Reychler’s academic career, for that matter – is sustainable peacebuilding architecture. Reychler introduced this concept in order to draw attention to the architectural principles and considerations that have to be addressed in sustainable peacebuilding processes. Reychler’s work on sustainable peacebuilding architecture has been groundbreaking and has not lost any of its relevance in the twenty-first century. By bringing together Reychler’s seminal texts on sustainable peacebuilding architecture, the current book aims to offer academics, students and policymakers an essential guide to understanding, studying and applying this crucial concept.• Provides a unique personal view of the development of peace research• Lists the necessary building blocks for sustainable peacebuilding• Offers tools for monitoring and evaluating interventions• Discusses the scientific nature and often provocative findings of peace research • Discusses ten lessons learned and the future (Peace Research III)

A Lucid Dreamer: The Life of Peter Redgrove
by Dr Neil Roberts Peter RedgroveThe work of the poet Peter Redgrove is one of the great unexplored treasures of late twentieth century literature. His prolific output presents an intriguing variety of personae: magician, scientist, lover, psychologist, joker, madman. It is only now, with the publication of his Collected Poems and this biography, that we can see how and why these personae developed - and discover the full depth and range of this visionary writer.Born into an apparently conventional middle-class family that was in reality deeply disturbed, the poet finally emerged: transforming himself from the neurotic, Oedipal young scientist, through a process of mental breakdown, insulin coma therapy, erotic revelation and the discovery of poetic companionship at Cambridge - and particularly his friendship and rivalry with Ted Hughes.Neil Roberts explores the inner story of this emergence, and Redgrove's later development through marriage, family life, the fellowship of the 'Group', alcoholic excess, infidelity and marital breakdown to his triumphant later partnership with Penelope Shuttle. We also discover, for the first time, some darker secrets: his fascination with Aleister Crowley, his damaged and damaging relationship with his father, and the lifelong sexual fetish which he called the 'Game'. Drawing on the poet's intimate journals and correspondence, and interviews with family, friends and colleagues, A Lucid Dreamer tells the exceptionally inward and revealing story of an astonishing creative life.
Lucid Dying: The New Science Revolutionizing How We Understand Life and Death
by Sam ParniaFrom internationally renowned expert in resuscitation and New York Times bestselling author Sam Parnia, MD, PhD, comes a groundbreaking look at what happens to us when we die, based on the largest-ever research study run on recalled experiences of death. Today, for the first time in history, the scientific exploration of death and what happens when we die is real, active and ongoing. Contrary to popular perceptions, this subject is no longer the remit of philosophy, religion, or personal opinion. Truly remarkable scientific discoveries that will fundamentally affect everyone&’s lives now and in the future are taking place, yet very few people are aware of them. Most people—including scientists and doctors—maintain strong beliefs about death and its experience. Those beliefs are rooted in traditional, and often cultural, notions of death. But what if all that we have come to believe about death is fundamentally wrong? What if the paradigm we have been operating within no longer exists? What if death is not the end we thought?Lucid Dying is the first book to share that science. Presenting data derived from multiple groundbreaking studies, Dr. Parnia shows that the entity we refer to as consciousness—our Self—does not seem to become annihilated when we die. In fact, during death, our consciousness vastly expands and leads to a vivid experience that follows a very specific narrative arc. These studies support that there really is a universal experience of death that is meaningful, transcendent, positive, and transformative—not hallucinatory, delusional, or illusory as previously imagined. In his latest book, Dr. Parnia weaves empirical research with gripping stories to show us the truth of how death is not the end we all thought and how anyone can harness the newfound wisdom to lead deeper, more intentional lives.
Lucifer's Legacy: The Meaning of Asymmetry
by Frank Close"This is Frank Close's masterpiece -- his best book, and one of the very best introductions to physics for the layperson. Close is a master expositor." -- The (London) Sunday Times"Close's writing is beguiling, mingling personal and historical anecdote with carefully measured doses of exposition in such a way as to guide the reader painlessly into rather deep intellectual waters." -- Nature "Life, intrinsically related to asymmetries, is the theme of this book, and Close offers us an absorbing and scientifically correct account of symmetry and its deep implications." -- CERN CourierThis thought-provoking work by a physicist and popular science writer explores the origins of asymmetry from the molecular level to that of the universe at large. Frank Close takes the readers on a tour of asymmetry that ranges from the development of human embryos to the mysterious Higgs boson, or "God particle," and ongoing research at Switzerland's CERN laboratory.
Lucky Planet: Why Earth is Exceptional-and What That Means for Life in the Universe
by David WalthamWhy Earth’s life-friendly climate makes it exceptional--and what that means for the likelihood of finding intelligent extraterrestrial life We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four billion year-stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others. Citing the factors that typically control a planet’s average temperature--including the size of its moon, as well as the rate of the Universe’s expansion--Waltham challenges the prevailing scientific consensus that Earth-like planets have natural stabilizing mechanisms that allow life to flourish. A lively exploration of the stars above and the ground beneath our feet, Lucky Planet seamlessly weaves the story of Earth and the worlds orbiting other stars to give us a new perspective of the surprising role chance plays in our place in the universe.

Lucy's Legacy: Sex And Intelligence In Human Evolution
by Alison Jolly<p>Alison Jolly believes that biologists have an important story to tell about being human--not the all-too-familiar tale of selfishness, competition, and biology as destiny but rather one of cooperation and interdependence, from the first merging of molecules to the rise of a species inextricably linked by language, culture, and group living. This is the story that unfolds in Lucy's Legacy, the saga of human evolution as told by a world-renowned primatologist who works among the female-dominant ringtailed lemurs of Madagascar. <p>We cannot be certain that Lucy was female--the bones themselves do not tell us. However, we do know, as Jolly points out in this erudite, funny, and informative book, that the females who came after Lucy--more adept than their males in verbal facility, sharing food, forging links between generations, migrating among places and groups, and devising creative mating strategies--played as crucial a role in the human evolutionary process as "man" ever did. In a book that takes us from the first cell to global society, Jolly shows us that to learn where we came from and where we go next, we need to understand how sex and intelligence, cooperation and love, emerged from the harsh Darwinian struggle in the past, and how these natural powers may continue to evolve in the future.</p>
Lucy's Legacy: The Quest for Human Origins
by Kate Wong Dr Donald Johanson"Lucy is a 3.2-million-year-old skeleton who has become the spokeswoman for human evolution. She is perhaps the best known and most studied fossil hominid of the twentieth century, the benchmark by which other discoveries of human ancestors are judged."-From Lucy's LegacyIn his New York Times bestseller, Lucy: The Beginnings of Humankind, renowned paleoanthropologist Donald Johanson told the incredible story of his discovery of a partial female skeleton that revolutionized the study of human origins. Lucy literally changed our understanding of our world and who we come from. Since that dramatic find in 1974, there has been heated debate and-most important-more groundbreaking discoveries that have further transformed our understanding of when and how humans evolved. In Lucy's Legacy, Johanson takes readers on a fascinating tour of the last three decades of study-the most exciting period of paleoanthropologic investigation thus far. In that time, Johanson and his colleagues have uncovered a total of 363 specimens of Australopithecus afarensis (Lucy's species, a transitional creature between apes and humans), spanning 400,000 years. As a result, we now have a unique fossil record of one branch of our family tree-that family being humanity-a tree that is believed to date back a staggering 7 million years.Focusing on dramatic new fossil finds and breakthrough advances in DNA research, Johanson provides the latest answers that post-Lucy paleoanthropologists are finding to questions such as: How did Homo sapiens evolve? When and where did our species originate? What separates hominids from the apes? What was the nature of Neandertal and modern human encounters? What mysteries about human evolution remain to be solved?Donald Johanson is a passionate guide on an extraordinary journey from the ancient landscape of Hadar, Ethiopia-where Lucy was unearthed and where many other exciting fossil discoveries have since been made-to a seaside cave in South Africa that once sheltered early members of our own species, and many other significant sites. Thirty-five years after Lucy, Johanson continues to enthusiastically probe the origins of our species and what it means to be human.From the Hardcover edition.
Ludwig Prandtl: Ein Unverstellter Blick Auf Sein Leben
by Michael EckertThis is a comprehensive biography of Ludwig Prandtl (1875-1953), the father of modern aerodynamics. His name is associated most famously with the boundary layer concept, but also with several other topics in 20th century fluid mechanics, particularly turbulence (Prandtl's mixing length). Among his disciples are pioneers of modern fluid mechanics such as Heinrich Blasius, Theodore von Kármán and Walter Tollmien. Furthermore, Prandtl founded the Aerodynamische Versuchsanstalt (AVA) and the Kaiser-Wilhelm-Institut für Strömungsforschung in Göttingen, both of them seeds for the growth of fluid mechanics in Germany. <P><P> Yet Prandtl was also a representative of aeronautical research - from Imperial Germany via the Weimar Republic to the "Third Reich". Although not a party member, he assumed the role of a goodwill ambassador for Nazi Germany. This objective treatment of his career will be of interest to all scientists and historians wanting to learn more about Prandtl's influence and the early development of fluid- and aerodynamics.

Ludwig Wittgenstein: To Francis Skinner – The Wittgenstein-Skinner Manuscripts
by Ludwig Wittgenstein Francis SkinnerIn this volume we witness Wittgenstein in the act of composing and experimenting with his new visions in philosophy. The book includes key explanations of the origin and background of these previously unknown manuscripts. It investigates how Wittgenstein’s philosophical thought-processes are revealed in his dictation to, as well as his editing and revision with Francis Skinner, in the latter’s role of amanuensis. The book displays a considerable wealth and variety of Wittgenstein’s fundamental experiments in philosophy across a wide array of subjects that include the mind, pure and applied mathematics, metaphysics, the identities of ordinary and creative language, as well as intractable problems in logic and life. He also periodically engages with the work of Newton, Fermat, Russell and others. The book shows Wittgenstein strongly battling against the limits of understanding and the bewitchment of institutional and linguistic customs. The reader is drawn in by Wittgenstein as he urges us to join him in his struggles to equip us with skills, so that we can embark on devising new pathways beyond confusion. This collection of manuscripts was posted off by Wittgenstein to be considered for publication during World War 2, in October 1941. None of it was published and it remained hidden for over two generations. Upon its rediscovery, Professor Gibson was invited to research, prepare and edit the Archive to appear as this book, encouraged by Trinity College Cambridge and The Mathematical Association. Niamh O’Mahony joined him in co-editing and bringing this book to publication.
Luft und Gesundheit: Von der globalen Zirkulation bis zu Atemwegserkrankungen
by Christian RügerIst frische Luft ein Mythos? In diesem Werk durchstreift der Autor die Lebensräume des Menschen und bietet Einblicke in die jeweils anzutreffenden Luftqualitäten. Aerosole steigen nicht von allein in die Luft auf. Die Partikel lösen sich aus dem festen oder flüssigen Verband. In der Luft kommen alle flugfähigen Masseteilchen miteinander in Kontakt – als ein anschauliches Beispiel dient dem Leser die Entstehung von Wassertropfen. Jede Luftschicht der Atmosphäre wirkt unterschiedlich auf die Atemluft ein und der Wind spielt dabei seine ganz eigene Rolle. Einerseits ist er Verteiler von Schadstoffen, und andererseits Garant frischer Luft am Erdboden. Die Verschmutzung der Luft ruft den Gesetzgeber auf den Plan. Wir erleben derzeit eine rasante Entwicklung von der Aufhebung der Zünfte bis zur Klimadiskussion.Große Relevanz für die Gesundheit besitzt die Schnittstelle zwischen Luft und Mensch: die Atemwege. Deren Schleimhäute stehen im Zentrum unserer Immunabwehr, und müssen einen „Etagenwechsel“ von Infektionen der oberen Atemwege in untere Lungenabschnitte verhindern. Diese und viele weitere spannende Zusammenhänge und Themen im breiten Spektrum zwischen Meteorologie und Atemwegserkrankungen werden anschaulich, gut zugänglich und anhand praktischer Beispiele abgehandelt, um sich eine sichere Plattform zur Beurteilung der Flut von Umweltnachrichten zu schaffen.

Lumbar Spinal Imaging in Radicular Pain and Related Conditions
by J. T. WilminkA general consensus exists,that lumbosacral nerve root compression is the primary cause of sciatica and neurogenic claudication, although humoral and vascular factors certainly play a role as well. This book focuses on imaging the various ways in which nerve root compression can come about, and determining which anatomic features are reliably associated with the production of radicular pain. After a discussion of the nature of radicular pain and related symptoms, spinal imaging techniques and options are reviewed, with emphasis on the role of MR myelography in assessing the intradural nerve roots. A chapter on normal topographic, sectional, and functional radiologic anatomy is followed by presentations on pathologic anatomy, addressing mechanisms of nerve root compression, and on pre- and postoperative imaging. Features relevant to prediction of the natural history are discussed, and a section is devoted to the performance and reporting of a spinal imaging study.
