Wobbling Motion in Nuclei: Transverse, Longitudinal, and Chiral (Springer Theses)
by Nirupama SensharmaThis thesis presents significant new observations of nuclear wobbling, and thus expands our understanding of nuclear triaxiality and its prevalence in the nuclear chart. Triaxial nuclear shapes are a very rare phenomena and their experimental identification often relies on two unique signatures – nuclear wobbling motion and chiral rotation. While nuclear chirality is a well-studied phenomenon, experimental observations of wobbling nuclei are rather limited. With the identification of 135Pr and 187Au as wobblers, this work establishes triaxiality to be a general phenomenon present in different regions of the nuclear chart, irrespective of any particular spin or deformation. A major focus of this work is the detailed investigation of the different kinds of wobbling modes. Depending on the geometry of the nuclear system, wobbling can be classified into two types – longitudinal and transverse. This work has, for the first time, reported evidence of the possible coexistence of both forms of wobbling in a single nucleus. Another important result reported in this work is the very first observation of co-existing chiral and wobbling modes in the 135Pr nucleus. This thesis details the experimental methods that led to this breakthrough, along with pertinent theoretical interpretations.
Woher kommt Gewalt?: Erklärungen aus Neurowissenschaften, Psychologie, Soziologie & Co
by Bernhard BogertsWarum tun Menschen so etwas!? Dies ist oft die erste Frage, die sich aufdrängt, wenn wir in den Medien oder im echten Leben Zeugen von Gewalt werden. Dieses Buch gibt umfassende Antworten: Es erklärt die Ursachen von Gewalt nicht aus der eingeschränkten Sicht einer einzelnen Fachdisziplin, sondern verbindet die Erklärungsansätze aus Hirnforschung, Kriminologie, Soziologie, Psychologie, Psychiatrie, Genetik, Pädagogik, Geschichtswissenschaften und Justiz zu einem großen, spannenden und verständlichen Bild – auf unterhaltsame Weise und auf dem aktuellen Stand der Wissenschaft(en). Und immer nah an Fallbeispielen, die uns die erschreckende Vielfalt menschlicher Gewalt vor Augen führen: Gewalthandlungen einzelner Täter, Gewalt zwischen Gruppen, Randale und Krawalle durch Gangs und Hooligans, gewaltsame ethnische und religiöse Konflikte, Extremgewalt in Form von Amok und Terror bis hin zu kriegerischen Auseinandersetzungen und Völkermord. Nicht zuletzt kann das Wissen aus diesem Buch dazu beitragen, eine andere große Frage zu beantworten: Wie kann Gewalt eingedämmt oder gar verhindert werden?

Wolf Conflicts: A Sociological Study (Interspecies Encounters #1)
by Ketil Skogen Olve Krange Helene FigariWolf populations have recently made a comeback in Northern Europe and North America. These large carnivores can cause predictable conflicts by preying on livestock, and competing with hunters for game. But their arrivals often become deeply embedded in more general societal tensions, which arise alongside processes of social change that put considerable pressure on rural communities and on the rural working class in particular. Based on research and case studies conducted in Norway, Wolf Conflicts discusses various aspects of this complex picture, including conflicts over land use and conservation, and more general patterns of hegemony and resistance in modern societies.
The Wolf Girls: An Unsolved Mystery from History
by Jane Yolen Heidi Elisabet Yolen StempleFrom the book jacket: In 1920 a missionary brought two young girls to an orphanage in India. The girls didn't know how to talk, walk, or eat from a plate. Some people thought the girls had been abandoned by their parents. Some people said the girls were brought up by wolves in the wild. Still others thought that the missionary who ran the orphanage made up the story about the girls. No one knows for sure. Become a detective as you read this true story study the clues, and try to figure out the fate of the wolf girls of Midnapore. The Unsolved Mystery from History series is written by acclaimed author Jane Yolen and former private investigator Heidi Elisabet Yolen Stemple. Read carefully and check your clues. You might be the first to solve a puzzle that has baffled people for years. Poet, novelist, storyteller, and picture-book author Jane Yolen has won four awards for her body of work in children's literature: the Regina Medal, the Kerlan Award, the Keene State Award, and the Boston Public Library's Literary Lights for Children Award.

Wolfenden's Witnesses: Homosexuality in Postwar Britain (Genders and Sexualities in History)
by Brian LewisThe Wolfenden Report of 1957 has long been recognized as a landmark in moves towards gay law reform. What is less well known is that the testimonials and written statements of the witnesses before the Wolfenden Committee provide by far the most complete and extensive array of perspectives we have on how homosexuality was understood in mid-twentieth century Britain. Those giving evidence, individually or through their professional associations, included a broad cross-section of official, professional and bureaucratic Britain: police chiefs, policemen, magistrates, judges, lawyers and Home Office civil servants; doctors, biologists (including Alfred Kinsey), psychiatrists, psychoanalysts and psychotherapists; prison governors, medical officers and probation officers; representatives of the churches, morality councils and progressive and ethical societies; approved school headteachers and youth organization leaders; representatives of the army, navy and air force; and a small handful of self-described but largely anonymous homosexuals. This volume presents an annotated selection of their voices.
Wolff-Parkinson-White and Other Preexcitation Syndromes: Simple to Complex Electrophysiology and Ablation of Accessory Pathways
by Ján HluchýThis book presents the features of Wolff-Parkinson-White and other preexcitation syndromes with detailed discussion of the management and treatment of these patients. Catheter ablation has become a curative first-line treatment for circus movement tachycardias involving accessory pathway conduction. However, diagnostic and interventional challenges may be associated with anatomically and electrophysiologically complex single accessory pathway conduction, multiple accessory pathways, accessory pathways with other coexistent tachycardias, including atrioventricular nodal reentrant tachycardia and atrial tachycardias, and accessory pathways with coexistent congenital heart disease. The complexity involved requires a thorough theoretical and practical knowledge for performing unequivocally conclusive/meaningful electrophysiological testing and successful catheter ablation. This book is based on the author’s personal long-term experience and contains over 700 illustrations of intracardiac recordings and fluoroscopic images, as well as clear and user-friendly descriptions of the electrophysiologic data, its analysis and interpretation. It therefore offers a comprehensive practical guide for mapping and catheter ablation. The systematic approach is also invaluable for accessory pathways coexistent with other arrhythmias or congenital heart diseases. Wolff-Parkinson-White and Other Preexcitation Syndromes presents the topic as a fascinating part of clinical cardiac electrophysiology and all types of corresponding accessory pathways, which are often associated with diagnostic and interventional challenges. It therefore provides an invaluable educational resource to further scientific and medical knowledge in the topic and will be essential reading for all electrocardiologists and any medical professional that manages these patients.
The Wolf's Tooth: Keystone Predators, Trophic Cascades, and Biodiversity
by Cristina EisenbergAnimals such as wolves, sea otters, and sharks exert a disproportionate influence on their environment; dramatic ecological consequences can result when they are removed from--or returned to--an ecosystem. In The Wolf's Tooth, scientist and author Cristina Eisenberg explores the concept of "trophic cascades" and the role of top predators in regulating ecosystems. Her fascinating and wide-ranging work provides clear explanations of the science surrounding keystone predators and considers how this notion can help provide practical solutions for restoring ecosystem health and functioning. Eisenberg examines both general concepts and specific issues, sharing accounts from her own fieldwork to illustrate and bring to life the ideas she presents. She considers how resource managers can use knowledge about trophic cascades to guide recovery efforts, including how this science can be applied to move forward the bold vision of rewilding the North American continent. In the end, the author provides her own recommendations for local and landscape-scale applications of what has been learned about interactive food webs. At their most fundamental level, trophic cascades are powerful stories about ecosystem processes--of predators and their prey, of what it takes to survive in a landscape, of the flow of nutrients. The Wolf's Tooth is the first book to focus on the vital connection between trophic cascades and restoring biodiversity and habitats, and to do so in a way that is accessible to a diverse readership.
Wolfsnail: A Backyard Predator
by Sarah C. CampbellA Theodor Seuss Geisel Honor BookPerfect for kids interested in animals, science, and the world of their backyard, this photographic story of a day in the life of a wolfsnail offers a dramatic introduction to a little-known predator and the impact it has on habitats where it does not belong.On a typical day, the wolfsnail hunts its prey: other snails. Big, strong, and fast (for a snail), the wolfsnail has a taste for meat, and in some areas, it is called the cannibal snail. On the prowl, the wolfsnail finds the slime trail of a smaller snail and follows the path toward its prey. When the chase ends and the dramatic feast is done, nothing remains of the smaller snail... except an empty shell. Slithering and suspenseful, this enlightening book also includes amazing facts about the wolfsnail and a glossary.
