Wechselwirkungen zwischen Landnutzung und Klimawandel
by Horst Gömann Johanna FickIn diesem Open Access Buch werden erstmals übergreifend die Entwicklungen bis 2030 in den Sektoren in Deutschland, welche die größte Fläche beanspruchen – Land- und Forstwirtschaft sowie Siedlung und Verkehr – aufgezeigt und die Wechselwirkungen zwischen Landnutzung und Klimawandel analysiert. Aufbauend auf einem akteursgestützten Diskurs von Handlungsoptionen zur Minderung von Treibhausgasemissionen sowie zur Anpassung an den Klimawandel werden unterschiedliche Landnutzungsstrategien entwickelt. Dabei wird auf die verschiedenen Schwerpunkte wie Klimaschutz, Bioenergie, Natur- und Umweltschutz sowie Klimaanpassung eingegangen. Die möglichen Auswirkungen der verschiedenen Strategien auf Nahrungs- und Rohstoffproduktion, Bioenergie, Umwelt und Natur sowie sozio-ökonomische Konsequenzen werden modellgestützt analysiert. Anhand der Ergebnisse zeigen die Autorinnen und Autoren sowohl auf, wie die Landnutzung in Deutschland zum Klimaschutz beitragen kann, als auch die Konflikte, die mit anderen gesellschaftlichen Zielen bestehen. Das Buch liefert eine Grundlage für die Debatte um eine klimawandeloptimierte Landnutzung in Deutschland.
The Wechsler Memory Scale: A Guide for Clinicians and Researchers
by Phillip L. KentThe Wechsler Memory Scale (WMS) is one of the most popular memory scales in the United States and much of the English-speaking world. This is the first book to systematically trace the evolution of the instrument in terms of its content and structure, whilst providing a guide to clinical interpretation and discussing its many research uses. The Wechsler Memory Scale: A Guide for Clinicians and Researchers provides a comprehensive review and synthesis of the literature on all the major editions and revisions of the WMS, including the Wechsler Memory Scale-I, Wechsler Memory Scale-Revised, Wechsler Memory Scale-III, and the Wechsler Memory Scale-IV. It discusses major factor analytic studies of each version of the test, clinical interpretation of each version including studies on malingering, uses of each version with special populations, and makes suggestions for the next revision (i.e, the WMS-V). This book is designed to be a go-to source for all graduate students, clinicians and researchers who use the Wechsler Memory Scale, as well as to institutions offering formal training in adult clinical and neuropsychological assessment.
Wednesday Is Indigo Blue: Discovering the Brain of Synesthesia
by Richard E. Cytowic David M. EaglemanHow the extraordinary multisensory phenomenon of synesthesia has changed our traditional view of the brain.A person with synesthesia might feel the flavor of food on her fingertips, sense the letter “J” as shimmering magenta or the number “5” as emerald green, hear and taste her husband's voice as buttery golden brown. Synesthetes rarely talk about their peculiar sensory gift—believing either that everyone else senses the world exactly as they do, or that no one else does. Yet synesthesia occurs in one in twenty people, and is even more common among artists. One famous synesthete was novelist Vladimir Nabokov, who insisted as a toddler that the colors on his wooden alphabet blocks were “all wrong.” His mother understood exactly what he meant because she, too, had synesthesia. Nabokov's son Dmitri, who recounts this tale in the afterword to this book, is also a synesthete—further illustrating how synesthesia runs in families. In Wednesday Is Indigo Blue, pioneering researcher Richard Cytowic and distinguished neuroscientist David Eagleman explain the neuroscience and genetics behind synesthesia's multisensory experiences. Because synesthesia contradicted existing theory, Cytowic spent twenty years persuading colleagues that it was a real—and important—brain phenomenon rather than a mere curiosity. Today scientists in fifteen countries are exploring synesthesia and how it is changing the traditional view of how the brain works. Cytowic and Eagleman argue that perception is already multisensory, though for most of us its multiple dimensions exist beyond the reach of consciousness. Reality, they point out, is more subjective than most people realize. No mere curiosity, synesthesia is a window on the mind and brain, highlighting the amazing differences in the way people see the world.
Weed Anatomy
by Hansjoerg Kraehmer Peter BaurWeeds affect everyone in the world by reducing crop yield and crop quality, delaying or interfering with harvesting, interfering with animal feeding (including poisoning), reducing animal health, preventing water flow, as plant parasites, etc. Weeds are common everywhere and cause many $ billions worth of crop losses annually, with the global cost of controlling weeds running into $ billions. The anatomy of plants is generally well understood, but the examples used for explanations in most books are often restricted to non-weed species. Weeds have many features that make them more competitive, for example enabling them to more quickly recover after herbicide treatment. Some of these adaptations include rhizomes, adapted roots, tubers and other special structures. Until now, no single book has concentrated on weeds’ anatomical features. A comprehensive understanding of these features is, however, often imperative to the successful implementation of many weed control measures. Beautifully and comprehensively illustrated, in full colour throughout, Weed Anatomy provides a comprehensive insight into the anatomy of the globally-important weeds of commercial significance. Commencing with a general overview of anatomy, the major part of the book then includes sections covering monocotyledons, dicotyledons, brackens and horsetails, with special reference to their anatomy. Ecological and evolutionary aspects of weeds are also covered and a number of less common weeds such as Adonis vernalis, Caucalis platycarpos and Scandix pecten-veneris are also included. The authors of this book, who have between them many years of experience studying weeds, have put together a true landmark publication, providing a huge wealth of commercially-important information. Weed scientists, plant anatomists and agricultural scientists, including personnel within the agrochemical and crop protection industry, will find a great deal of useful information within the book’s covers. All libraries in universities and research establishments where agricultural and biological sciences are studied and taught should have copies of this exceptional book on their shelves.
Weed Control: Sustainability, Hazards, and Risks in Cropping Systems Worldwide
by Nicholas E. Korres Nilda R. Burgos Stephen O. DukeIn light of public concerns about sustainable food production, the necessity for human and environmental protection, along with the evolution of herbicide resistant weeds, call for a review of current weed control strategies. Sustainable weed control requires an integrated approach based on knowledge of each crop and the weeds that threaten it. This book will be an invaluable source of information for scholars, growers, consultants, researchers and other stakeholders dealing with either arable, row, cash, vegetables, orchards or even grassland-based production systems. The uniqueness of this book comes from the balanced coverage of herbicide effects on humans and environment in relation to best weed control practices of the most important cropping systems worldwide. Furthermore, it amalgamates and discusses the most appropriate, judicious and suitable weed control strategies for a wide range of crops. It reviews the available information and suggests solutions that are not merely feasible but also optimal.
Weed Control Methods for Public Health Applications
by E.O. GangstadThis volume includes measures of control of aquatic vegetation that harms human health, since water-related diseases exist in this environment. Although malaria has receded internationally due to the combined chemotherapeutic-insecticidal programs, recently it has resisted both medicines and insecticide control. Active malaria cases in the U.S. were fewer than a dozen before the Vietnam War, but in 1973 the figure was ab out 700, almost all traceable to returning military personnel. The disease could again become prevalent. Other diseases exist whose transmission is indirectly affected by aquatic weed conditions including filariasis, and various trematodiases, especially from the schistosomes, Chinese liver fluke, cattle liver fluke, Guinea worm, giant intestinal fluke, Asiatic lung fluke, and broad tapeworm. Waterweeds also support disease-pest arthropods, i.e., snipe flies, tabanids (horse, gad, deer, and greenheads), Clear Lake gnats, Mayflies, black flies, sandflies, and sewage flies.Ecosystem studies of impounded water research and development of herbivorous fish, and utilization of herbivorous fish in China, are also included in this volume.
Weed Control Methods For Recreation Facilities Management
by Edward O. GangstadIt is the purpose of this volume to survey and assess the management problems of recreation waters and to present case problems from the field in which the technical data, published literature, and the operations mechanics are given in sufficient detail to provide a format for practical analysis and application. Special emphasis has been given to measures of control of Eurasian watermilfoil.The primary and secondary uses of a body of water determine the need, frequency, and kind of aquatic plant control required to meet the needs of a specific situation. That is to say, a given body of water may be used primarily, or even exclusively for such activities as fishing, boating, or swimming, and the water itself may be used for domestic (potable water), industrial production, and/or agriculture. These uses may seem to be incompatible in themselves, but it is incumbent upon management to supply the optimum conditions for total water use.
Weed Control Methods for Rights of Way Management
by Edward O. GangstadThis volume describes in detail methods of control and related data including (1) all vegetation on industrial sites, paved highways, and railroad ballast, (2) woody vegetation along roadsides, utility lines, and fire breaks, and (3) aquatic vegetation on rivers and stream banks, waterways, ponds, reservoirs, irrigation, and drainage channels.
Weed Control Methods for River Basin Management
by E.O. GangstadAquatic plants continue to create problems associated with navigation, flood control, agriculture, irrigation and drainage, values of lands, conservation of wildlife and fisheries, and water resource supply. While much research is being done to find more effective and economic control measures, there is now a great need to apply known facts to achieve a measure of control by the means available. It is the purpose of this volume to provide a scientifically documented treatise of the known facts as they apply to the control of aquatic weeds in river basins and their allied waterways with particular emphasis on alligator weed and water hyacinth.
A Weed is a Flower: The Life of George Washington Carver
by AlikiBrief text and pictures present the life of George Washington Carver, born a slave, who became a scientist and devoted his entire life to helping the South improve its agriculture.
Weed Physiology: Volume 2: Herbicide Physiology
by Stephen O. DukeVolume 2 deals with the mechanisms of herbicide action and of resistance and tolerance to herbicides. The first five chapters of this volume cover the effects of herbicides and adjuvants on the physiology of plants. Professor Black‘s chapter begins by covering the effects of herbicides on photosynthesis, including photosynthetic assimilation of nitrogen, sulfur, and phosphorus. This is followed by Dr. Morelands chapter on herbicide interactions with plant respiration. The third chapter by Professor Bartels deals with the effects of herbicides on chloroplast and cellular development with emphasis on correlating physiological information with ultrasound effects.
Weed Physiology: Volume I: Reproduction and Ecophysiology
by Stephen O. DukeWeeds are plants existing at places and/or times at which they are considered undesirable by man. Thys, man‘s primary interest in weeds is in dinging methods for eliminating their presences. Understanding the physiology of weeds and how it differs from that of crop plants is becoming increasingly important in discovering new chemical, genetic, and cultural methods of controlling weeds. The two volumes of this book will aim to discuss the following; the physiology of weed production the ecophysiology of weeds, the mechanisms of herbicide action, and the mechanisms of herbicide resistance and tolerance.
Weed Research: Expanding Horizons
by Robert J. Froud-Williams Paul E. HatcherThis book presents the most up-to-date and comprehensive guide to the current and potential future state of weed science and research. Weeds have a huge effect on the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding (including poisoning), reducing animal health and preventing water flow. They are common across the world and cost billions of dollars’ worth of crop losses year on year, as well as billions of dollars in the annual expense of controlling them. An understanding of weeds is vital to their proper management and control, without which the reduction in crop yields that they would cause could lead to mass starvation across the globe. Topics covered include weed biology and ecology, control of weeds and particular issues faced in their control. Authored and edited by internationally renowned scientists in the field all of whom are actively involved in European Weed Research Society working groups, this succinct overview covers all the relevant aspects of the science of weeds. Weed Research: Expanding Horizons is the perfect resource for botanists, horticultural scientists, agronomists, weed scientists, plant protection specialists and agrochemical company personnel.
Weeds: In Defense of Nature's Most Unloved Plants
by Richard Mabey“[A] witty and beguiling meditation on weeds and their wily ways….You will never look at a weed, or flourish a garden fork, in the same way again.”—Richard Holmes, author of The Age of Wonder“In this fascinating, richly detailed book, Richard Mabey gives weeds their full due.”—Carl Zimmer, author of EvolutionRichard Mabey, Great Britain’s Britain’s “greatest living nature writer” (London Times), has written a stirring and passionate defense of nature’s most unloved plants. Weeds is a fascinating, eye-opening, and vastly entertaining appreciation of the natural world’s unappreciated wildflowers that will appeal to fans of David Attenborough, Robert Sullivan’s Rats, Amy Stewart’s Wicked Plants, and to armchair gardeners, horticulturists, green-thumbs, all those who stop to smell the flowers.
Weeds of North America
by Richard Dickinson France RoyerAmerican Horticultural Society Book Award Winner: “An essential reference for all who wish to understand the science of the all-powerful weed.” —Better Homes and Gardens“What is a weed,” opined Emerson, “but a plant whose virtues have not yet been discovered?” While that may be a worthy notion in theory, these plants of undiscovered virtue cause endless hours of toil for backyard gardeners. Wherever they take root, weeds compete for resources, and most often win. They also wreak havoc on industry—from agriculture to golf courses to civic landscape projects, vast amounts of money are spent to eradicate these virile and versatile invaders. With so much at stake, reliable information on weeds and their characteristics is crucial. Richard Dickinson and France Royer shed light on this complex world with Weeds of North America.Organized by plant family, this encyclopedic volume features over five hundred species in two-page spreads with images and text identification keys. Species are arranged within family alphabetically by scientific name, and entries include vital information on seed viability and germination requirements. No matter what your philosophy on weeds, this guide provides much-needed background on these intrusive organisms. In the battle with weeds, knowledge truly is power, and Weeds of North America is perfect for gardeners, botanists, nature lovers, or anyone working in the business of weed ecology and control.“Royer’s photographs are almost perversely alluring. . . . How can you not be ensnared by a book populated by prostrate pigweed, tansy ragwort and dog-strangling vine?” —New York Times Book Review

Wegbereiter der subatomaren Physik: James Chadwick und Charles D. Ellis (essentials)
by Gerhard EckerDas Energiespektrum der Elektronen beim Betazerfall war lange Zeit umstritten. 1914 fand Chadwick Hinweise auf ein kontinuierliches Energiespektrum, doch seine Ergebnisse wurden nicht allgemein anerkannt. Chadwick und Ellis lernten einander in einem deutschen Internierungslager während des 1. Weltkriegs kennen. Ellis gelang im Jahre 1927 der endgültige Beweis für das kontinuierliche Spektrum. Damit war der Weg frei für Paulis Neutrino-Hypothese und für die Fermi-Theorie der schwachen Wechselwirkung. In Streuexperimenten mit Alphateilchen fanden Rutherford, Chadwick und andere ab 1920 Hinweise auf eine bis dahin unbekannte Kernkraft, die wir heute als starke Wechselwirkung bezeichnen. Die Entdeckung des Neutrons durch Chadwick im Jahre 1932 war ein entscheidender Beitrag zum Verständnis beider Kernkräfte. Die Biografien der beiden Physiker werden beleuchtet.
Wege aus der Klimakatastrophe: Wie eine nachhaltige Energie- und Klimapolitik gelingt
by Lars JaegerÜberschwemmungen, Artensterben, Völkerwanderungen, Dürren, Supertornados - der Klimawandel ist keine am Horizont drohende Gefahr mehr, sondern längst in unserem Alltag angekommen. Die Lage ist sehr ernst, aber wir haben durchaus Konzepte, den verheerenden Klimatrend aufzuhalten und umzukehren.Alle durch den Menschen erzeugten klimarelevanten Einflüsse lassen sich auf einen einzigen Faktor zurückführen: Energie. Wer die aktuelle Klimadynamik stoppen und sogar umkehren will, muss daher auch auf die drei zentralen Fragen zur Energie und dem Klima eine Antwort finden: Wie genau beeinflusst unsere bestehende Art des Energieverbrauchs das Klima? Welche Möglichkeiten haben wir, Energie ohne negative Klimaeffekte zu erzeugen? Welche technologischen Fortschritte werden uns dabei in der Zukunft konkret helfen?Lars Jaeger gibt einen Ausblick auf eine mögliche klimafreundliche Wirtschaft der Zukunft, beschreibt, wie eine ökologische Gesellschaft funktionieren kann und wie lokale Energiekonzepte weltweiten Erfolg haben können. Er kommt dabei mit einer klaren und optimistischen Botschaft: Wir verfügen schon heute über die technischen Möglichkeiten (und in der Zukunft umso mehr), um den verheerenden Klimatrend ohne signifikante Wohlstandsbeschränkung umzukehren. Die Hindernisse liegen vor allem in ökonomischen und politischen „Sachzwängen“ und partikulären wirtschaftlichen Interessenskonflikten. Diese zu überwinden, darum geht es in der zukünftigen Energiepolitik.
The Weierstrass Elliptic Function and Applications in Classical and Quantum Mechanics: A Primer for Advanced Undergraduates (SpringerBriefs in Physics)
by Georgios PastrasThe field of elliptic functions, apart from its own mathematical beauty, has many applications in physics in a variety of topics, such as string theory or integrable systems. This book, which focuses on the Weierstrass theory of elliptic functions, aims at senior undergraduate and junior graduate students in physics or applied mathematics. Supplemented by problems and solutions, it provides a fast, but thorough introduction to the mathematical theory and presents some important applications in classical and quantum mechanics. Elementary applications, such as the simple pendulum, help the readers develop physical intuition on the behavior of the Weierstrass elliptic and related functions, whereas more Interesting and advanced examples, like the n=1 Lamé problem-a periodic potential with an exactly solvable band structure, are also presented.
Weigh Them All!: Cosmological Searches for the Neutrino Mass Scale and Mass Ordering (Springer Theses)
by Sunny VagnozziThe three neutrinos are ghostly elementary particles that exist all across the Universe. Though every second billions of them fly through us, they are extremely hard to detect. We used to think they had no mass, but recently discovered that in fact they have a tiny mass. The quest for the neutrino mass scale and mass ordering (specifying how the three masses are distributed) is an extremely exciting one, and will open the door towards new physics operating at energy scales we can only ever dream of reaching on Earth. This thesis explores the use of measurements of the Cosmic Microwave Background (the oldest light reaching us, a snapshot of the infant Universe) and maps of millions of galaxies to go after the neutrino mass scale and mass ordering. Neutrinos might teach us something about the mysterious dark energy powering the accelerated expansion of the Universe, or about cosmic inflation, which seeded the initial conditions for the Universe. Though extremely baffling, neutrinos are also an exceptionally exciting area of research, and cosmological observations promise to reveal a great deal about these elusive particles in the coming years.
Weighing the Future: Race, Science, and Pregnancy Trials in the Postgenomic Era (Critical Environments: Nature, Science, and Politics #9)
by Natali ValdezEpigenetics, the study of heritable changes in gene expression, has been heralded as one of the most promising new fields of scientific inquiry. Current large-scale studies selectively draw on epigenetics to connect behavioral choices made by pregnant people, such as diet and exercise, to health risks for future generations. As the first ethnography of its kind, Weighing the Future examines the sociopolitical implications of ongoing pregnancy trials in the United States and the United Kingdom, illuminating how processes of scientific knowledge production are linked to capitalism, surveillance, and environmental reproduction. Natali Valdez argues that a focus on individual behavior rather than social environments ignores the vital impacts of systemic racism. The environments we imagine to shape our genes, bodies, and future health are intimately tied to race, gender, and structures of inequality. This groundbreaking book makes the case that science, and how we translate it, is a reproductive project that requires feminist vigilance. Instead of fixating on a future at risk, this book brings attention to the present at stake.
Weighing the Soul: The Evolution of Scientific Beliefs
by Dr Len FisherFrom the IgNobel-winning author of How to Dunk a Doughnut, another slice of the weird and wonderful side of scienceGood science and common sense often don't mix. In Weighing the Soul, Len Fisher shows the path to scientific discovery is frequently a bumpy one that follows Schopenhauer's famous maxim - 'All truth passes through three stages: First, it is ridiculed; Second, it is violently opposed; and Third, it is accepted as self-evident.' Fisher tells the fascinating, human stories behind some of the great as well as some of the not-so-great scientific ideas of the past - those that were truly bizarre, peculiar or downright daft, and those that just seemed that way at the time. As he shows, it is often only with hindsight that the two can be told apart, and it is some of those who appeared most wrong - and who were variously ignored, persecuted and imprisoned as a result - that ultimately went on to be proved most right.

Weighing the Soul: Scientific Discovery from the Brilliant to the Bizarre
by Len FisherFrom the man who "puts the fizz in physics" (Entertainment Weekly), an entertaining and thought-provoking foray into the science of the bizarre, the peculiar, and the downright nutty! Winner of the IgNobel Prize in physics and the 2004 American Institute of Physics Science Writing Award, Len Fisher showed just how much fun science can be in his enthusiastically praised debut, How to Dunk a Doughnut. In this new work, he reveals that science sometimes takes a path through the ridiculous and the bizarre to discover that Nature often simply does not follow common sense. One experiment, involving a bed, platform scales, and a dying man, seemed to prove that the soul weighed the same as a slice of bread. But other, no less fanciful experiments and ideas led to the fundamentals of our understanding of movement, heat, light, and energy, and such things as the discovery of electricity, and the structure of DNA; improved engines; and the invention of computers. As in his previous book, Fisher uses personal stories and examples from everyday life, as well as humor, to make the science accessible. He touches on topics from lightning to corsets and from alchemy to Frankenstein and water babies, but he may not claim the last word on the weight of the soul!
