Bronze Age Warfare
by Richard Osgood Sarah MonksThe Bronze Age, so named because of the technological advances in metalworking and countless innovations in the manufacture and design of tools and weapons, is among the most fascinating periods in human history. Archaeology has taught us much about the way of life, habits and homes of Bronze Age people, but as yet little has been written about warfare. What was Bronze Age warfare like? How did people fight and against whom? What weapons were used? Did they fortify their settlements, and, if so, were these intended as defensive or offensive structures? in response to these and many other questions, Bronze Age Warfare offers and intriguing insight into warfare and society, life and death in Europe 4000 years ago. It describes the surviving evidence of conflict - fortifications, weapons and body protection, burials, human remains and pictorial evidence - and seeks to understand the role played by aggression in the prehistoric world.

Broken Places & Outer Spaces: Finding Creativity In The Unexpected (Ted 2 Ser.)
by Nnedi OkoraforNnedi Okorafor was never supposed to be paralyzed. A college track star and budding entomologist, Nnedi’s lifelong battle with scoliosis was just a bump in her plan - something a simple surgery would easily correct. But when Nnedi wakes from the surgery to find she can’t move her legs, her entire sense of who she is begins to waver. Confined to a hospital bed for months, unusual things begin to happen. Psychedelic bugs crawl her hospital walls; strange dreams visit her nightly. She begins to feel as if she’s turning into a cyborg. Unsure if she’ll ever walk again, Nnedi begins to put these experiences into writing, conjuring up strange, fantastical stories. What Nnedi discovers during her confinement would prove to be the key to her life as a successful science fiction writer: In science fiction, when something breaks, something greater often emerges from the cracks. While she may be bedridden, instead of stopping her journey Nnedi’s paralysis opens up new windows in her mind, kindles her creativity and ultimately leads her to become more alive than she ever could have imagined. Nnedi takes the reader on a journey from her hospital bed deep into her memories, from her painful first experiences with racism as a child in Chicago to her powerful visits to her parents’ hometown in Nigeria, where she got her first inkling that science fiction has roots beyond the West. This was not the Africa that Nnedi knew from Western literature - an Africa that she always read was a place left behind. The role of technology in Nigeria opened her eyes to future-looking Africa: cable TV and cell phones in the village, 419 scammers occupying the cybercafés, the small generator connected to her cousin’s desktop computer, everyone quickly adapting to portable tech devices due to unreliable power sources. Nnedi could see that Africa was far from broken, as she’d been taught, and her experience there planted the early seeds of sci-fi - a genre that speculates about technologies, societies, and social issues - from an entirely new lens. In Broken Places & Outer Spaces, Nnedi uses her own experience as a jumping off point to follow the phenomenon of creativity born from hardship. From Frida Kahlo to Mary Shelly, she examines great artists and writers who have pushed through their limitations, using hardship to fuel their work. Through these compelling stories and her own, Nnedi reveals a universal truth: What we perceive as limitations have the potential to become our greatest strengths - far greater than when we were unbroken.
Broken Movement: The Neurobiology of Motor Recovery after Stroke (The\mit Press Ser.)
by S. Thomas Carmichael John W. KrakauerAn account of the neurobiology of motor recovery in the arm and hand after stroke by two experts in the field.Stroke is a leading cause of disability in adults and recovery is often difficult, with existing rehabilitation therapies largely ineffective. In Broken Movement, John Krakauer and S. Thomas Carmichael, both experts in the field, provide an account of the neurobiology of motor recovery in the arm and hand after stroke. They cover topics that range from behavior to physiology to cellular and molecular biology. Broken Movement is the only accessible single-volume work that covers motor control and motor learning as they apply to stroke recovery and combines them with motor cortical physiology and molecular biology. The authors cast a critical eye at current frameworks and practices, offer new recommendations for promoting recovery, and propose new research directions for the study of brain repair.Krakauer and Carmichael discuss such subjects as the behavioral phenotype of hand and arm paresis in human and non-human primates; the physiology and anatomy of the motor system after stroke; mechanisms of spontaneous recovery; the time course of early recovery; the challenges of chronic stroke; and pharmacological and stem cell therapies. They argue for a new approach in which patients are subjected to higher doses and intensities of rehabilitation in a more dynamic and enriching environment early after stroke. Finally they review the potential of four areas to improve motor recovery: video gaming and virtual reality, invasive brain stimulation, re-opening the sensitive period after stroke, and the application of precision medicine.
Broken Hearts: The Tangled History of Cardiac Care
by David S. JonesA history illustrating the complexity of medical decision making and risk.Still the leading cause of death worldwide, heart disease challenges researchers, clinicians, and patients alike. Each day, thousands of patients and their doctors make decisions about coronary angioplasty and bypass surgery. In Broken Hearts David S. Jones sheds light on the nature and quality of those decisions. He describes the debates over what causes heart attacks and the efforts to understand such unforeseen complications of cardiac surgery as depression, mental fog, and stroke.Why do doctors and patients overestimate the effectiveness and underestimate the dangers of medical interventions, especially when doing so may lead to the overuse of medical therapies? To answer this question, Jones explores the history of cardiology and cardiac surgery in the United States and probes the ambiguities and inconsistencies in medical decision making. Based on extensive reviews of medical literature and archives, this historical perspective on medical decision making and risk highlights personal, professional, and community outcomes.

Broadening the Genetic Base of Grain Legumes
by Mohar Singh Ishwari Singh Bisht Manoranjan DuttaGrain legumes play significant and diverse role in the farming systems and provide nutrition security to the largely vegetarian and relatively poorer people around the world. These are ideal crops for achieving three simultaneous developmental goals viz. reducing poverty, improving human health and nutrition and enhancing ecosystem resilience. Globally, grain legumes are the second most important crop group next only to cereals but a large proportion of area of it is under rainfed-low input systems as compared to cereals contributing to lower yields. The other important factor responsible for reduced yield in grain legumes is the narrow genetic base of the present day pulse varieties. In order to break the yield barriers of these cultivars, new sources of genes/ alleles need to be identified and suitably incorporated into the adapted background. The information on various aspects of grain legume improvement although has been considerable in the recent past, these information are highly scattered and not available at one place. The present book consists of comprehensive and latest crop-wise information on important grain legumes of the world including their distribution, gene pool, systematics, status of genetic and genomic resources, production constraints, traits of importance, crop improvement methodologies - both conventional as well as contemporary and future strategies to be adopted for comprehensive grain legume improvement in various agro-ecological target areas of the globe. The chapters have been contributed by eminent crop experts from across the world engaged in research in their respective crops for the past several years thus providing a rare insight into the crop specific constraints and prospects drawing from their rich overall experience. The book therefore will be a useful source of information to the grain legume researchers, students, policy planners and developmental experts alike.

Broadcasting Fidelity: German Radio and the Rise of Early Electronic Music
by Myles W. JacksonA landmark history of early radio in Germany and the quest for broadcast fidelityWhen we turn on a radio or stream a playlist, we can usually recognize the instrument we hear, whether it&’s a cello, a guitar, or an operatic voice. Such fidelity was not always true of radio. Broadcasting Fidelity shows how the problem of broadcast fidelity pushed German scientists beyond the traditional bounds of their disciplines and led to the creation of one of the most important electronic instruments of the twentieth century.In the early days of radio, acoustical distortions made it hard for even the most discerning musical ears to differentiate instruments and voices. The physicists and engineers of interwar Germany, with the assistance of leading composers and musicians, tackled this daunting technical challenge. Research led to the invention in 1930 of the trautonium, an early electronic instrument capable of imitating the timbres of numerous acoustical instruments and generating novel sounds for many musical genres. Myles Jackson charts the broader political and artistic trajectories of this instrument, tracing how it was embraced by the Nazis and subsequently used to subvert Nazi aesthetics after the war and describing how Alfred Hitchcock commissioned a later version of the trautonium to provide the sounds of birds squawking and flapping their wings in his 1963 thriller The Birds.A splendid work of scholarship by an acclaimed historian of science, Broadcasting Fidelity reveals how the interplay of science, technology, politics, and culture gave rise to new aesthetic concepts, innovative musical genres, and the modern discipline of electroacoustics.

Broadband Measurement and Reduction of Quantum Radiation Pressure Noise in the Audio Band (Springer Theses)
by Jonathan CripeThis book presents a direct measurement of quantum back action, or radiation pressure noise, on a macroscopic object at room temperature across a broad bandwidth in the audio range. This noise source was predicted to be a limitation for gravitational wave interferometers in the 1980s, but it has evaded direct characterization in the gravitational wave community due to the inherent difficult of reducing thermal fluctuations below the quantum back action level. This back action noise is a potential limitation in Advanced LIGO and Advanced Virgo, and Cripe’s experiment has provided a platform for the demonstration of quantum measurement techniques that will allow quantum radiation pressure noise to be reduced in these detectors. The experimental techniques Cripe developed for this purpose are also applicable to any continuous measurement operating near the quantum limit, and could lead to the possibility of observing non-classical behavior of macroscopic objects.
Broad Bandwidth and High Dimensional Quantum Memory Based on Atomic Ensembles (Springer Theses)
by Dong-Sheng DingThis thesis presents an experimental study of quantum memory based on cold atomic ensembles and discusses photonic entanglement. It mainly focuses on experimental research on storing orbital angular momentum, and introduces readers to methods for storing a single photon carried by an image or an entanglement of spatial modes. The thesis also discusses the storage of photonic entanglement using the Raman scheme as a step toward implementing high-bandwidth quantum memory. The storage of photonic entanglement is central to achieving long-distance quantum communication based on quantum repeaters and scalable linear optical quantum computation. Addressing this key issue, the findings presented in the thesis are very promising with regard to future high-speed and high-capacity quantum communications.
British and Irish Butterflies: An Island Perspective
by Roger L Dennis Peter B HardyIslands are special places; they can be havens for unique plants and animals and refuges for wildlife. This book investigates the biogeography of butterfly species over the British islands, particularly the factors that influence their presence on the islands and that have made each island's butterfly fauna distinctive. The book contains a full log of records of species on the islands and much supporting information. The first three chapters set the scene, illustrating the basics of island biogeography theory, their changing circumstances during the current Holocene interglacial, and studies of natural history of British butterflies that mark the islands as the most intensively studied region for wildlife in the world. The book advances by increasing resolution downscale from a European continental perspective, through patterns and changes on the British mainland, a comparison of the two dominant islands of Britain and Ireland, to a close inspection of the dynamics of species on the multitude of offshore islands. Detailed investigations include contrasts in species' richness on the islands and then of the incidences of each species. Case studies highlight the continual turnover of species on islands. Attention is then given to evolutionary changes since the time that glaciers enveloped Europe. A powerful message is conveyed for the maintenance of butterfly species on the smaller British islands now experiencing population losses at a rate unprecedented since the spread of the last ice sheets: the incontrovertible importance of maintaining populations of species on nearby mainland sources for islands as pools for future migrants. This book is enhanced with supporting material. To access the Online Supplementary Appendices below, please visit: http://www.cabi.org/openresources/95061.
