Defects at Oxide Surfaces
by Jacques Jupille Geoff ThorntonThis book presents the basics and characterization of defects at oxide surfaces. It provides a state-of-the-art review of the field, containing information to the various types of surface defects, describes analytical methods to study defects, their chemical activity and the catalytic reactivity of oxides. Numerical simulations of defective structures complete the picture developed. Defects on planar surfaces form the focus of much of the book, although the investigation of powder samples also form an important part. The experimental study of planar surfaces opens the possibility of applying the large armoury of techniques that have been developed over the last half-century to study surfaces in ultra-high vacuum. This enables the acquisition of atomic level data under well-controlled conditions, providing a stringent test of theoretical methods. The latter can then be more reliably applied to systems such as nanoparticles for which accurate methods of characterization of structure and electronic properties have yet to be developed. The book gives guidance to tailor oxide surfaces by controlling the nature and concentration of defects. The importance of defects in the physics and chemistry of metal oxide surfaces is presented in this book together with the prominent role of oxides in common life. The book contains contributions from leaders in the field. It serves as a reference for experts and beginners in the field.
Defects Engineering in Electroceramics for Energy Applications (Engineering Materials)
by Upendra KumarThis book highlights the history of electroceramics starting from synthesis using different routes of the solid solution to hybrid nanocomposites and its applications in different renewable energy, thermistor, actuators, thermoelectric, thermo-optic, sensor, and much more applications in electronic industry. In ceramic materials, the properties are controlled by doping and composition, but the grain size and the porosity of the sintered ceramics also play essential roles. The latter features depend on the method of fabrication. The end-user requirements define the optimum physical and chemical properties of ceramic materials. Therefore, the design and fabrication of ceramic components are multidisciplinary, spanning physical chemistry, metallurgy, and chemical engineering. Also included in this book are the various characterizing techniques to study the physical properties of ceramics.

Defects in Self-Catalysed III-V Nanowires (Springer Theses)
by James A. GottThis thesis presents an in-depth exploration of imperfections that can be found in self-catalysed III-V semiconductor nanowires. By utilising advanced electron microscopy techniques, the interface sharpness and defects at the atomic and macroscopic scale are analysed. It is found that a surprising variety and quantity of defect structures can exist in nanowire systems, and that they can in fact host some never-before-seen defect configurations. To probe how these defects are formed, conditions during nanowire growth can be emulated inside the microscope using the latest generation of in-situ heating holder. This allowed the examination of defect formation, dynamics, and removal, revealing that many of the defects can in fact be eliminated. This information is critical for attaining perfect nanowire growth. The author presents annealing strategies to improve crystal quality, and therefore device performance.
Defence Against Bioterrorism: Methods For Prevention And Control (NATO Science For Peace And Security Series B: Physics and Biophysics)
by Vladan Radosavljevic Goran Belojevic Ines BanjariThis volume is based on a multidisciplinary approach towards biological and chemical threats that can, and have been previously used in bioterrorism attacks around the globe. Current knowledge and evidence-based principles from the fields of synthetic biology, microbiology, plant biology, chemistry, food science, forensics, tactics, infective medicine, psychology and others are compiled to address numerous aspects and the complexity of bioterrorism attacks. The main focus is on biological threats, especially in the context of synthetic biology and its emerging findings that can be observed as possible threat and tool. The book examines microorganisms and their possible use in forensics, i.e. as possible detection tool that could enable fast and precise detection of possible treats. A number of plant derived components are also discussed as possible agents in bioterrorism attacks, and in relation to infectious disease pathology. Another integral part is food safety, especially in terms of large food supply chains, like airline caterings, institutionalized kitchens etc. Food can be observed as a possible mean of delivery of various agents (biological and chemical) for bioterrorism attacks. Steps on how to recognize specific critical points in a food supply chain, along with proposed corrective activities are discussed.Examples from around the globe, along with the methodological approach on how to differentiate bioterrorism attacks from other epidemics are provided. However, epidemics are also discussed in the context of migrations, with the special emphasis on the current refugee migrations that affect not only Europe, but also the United States. The book will be of interest to experts from various fields of science as well as professionals working in the field. The book encompasses examples and tools developed for easier, more specific, and faster detection of possible bioterrorism treats, along with proposed actions for some aspects of a bioterrorism attack.

Defending Beef: The Case for Sustainable Meat Production
by Nicolette Hahn NimanFor decades it has been nearly universal dogma among environmentalists and health advocates that cattle and beef are public enemy number one. But is the matter really so clear cut? Hardly, argues environmental lawyer turned rancher Nicolette Hahn Niman in her new book, Defending Beef. The public has long been led to believe that livestock, especially cattle, erode soils, pollute air and water, damage riparian areas, and decimate wildlife populations. In Defending Beef, Hahn Niman argues that cattle are not inherently bad for either the Earth or our own nutritional health. In fact, properly managed livestock play an essential role in maintaining grassland ecosystems by functioning as surrogates for herds of wild ruminants that once covered the globe. Hahn Niman argues that dispersed, grass-fed, small-scale farms can and should become the basis for American food production, replacing the factory farms that harm animals and the environment. The author--a longtime vegetarian--goes on to dispel popular myths about how eating beef is bad for our bodies. She methodically evaluates health claims made against beef, demonstrating that such claims have proven false. She shows how foods from cattle--milk and meat, particularly when raised entirely on grass--are healthful, extremely nutritious, and an irreplaceable part of the world's food system. Grounded in empirical scientific data and with living examples from around the world, Defending Beef builds a comprehensive argument that cattle can help to build carbon-sequestering soils to mitigate climate change, enhance biodiversity, help prevent desertification, and provide invaluable nutrition. Defending Beef is simultaneously a book about big ideas and the author's own personal tale--she starts out as a skeptical vegetarian and eventually becomes an enthusiastic participant in environmentally sustainable ranching. While no single book can definitively answer the thorny question of how to feed the Earth's growing population, Defending Beef makes the case that, whatever the world's future food system looks like, cattle and beef can and must be part of the solution.
Defending An Economic Superpower: Reassessing The U.s.-japan Security Alliance
by Tetsuya KataokaThis book describes the reassessment of the U.S.-Japan security relationship to determine how Japan can do more for its defense, reduce America's spending for Japan's and Asia's security, yet preserve the peace in that region. It raises six questions about the relationship and tries to answer them.
Defending The Island: From Caesar to the Armada
by Norman LongmateIn a brilliantly imaginative blend of military, social and diplomatic history, Norman Longmate retells our island story from the perspective of its defenders, in a narrative which stretches from the Celtic tribes who unsuccessfully fought against Ceasar to the great seabourne defence against the Armada of Philip of Spain. He has gone back to the original sources and investigated the original battlegrounds and weak spots in Britain's defences. But the real strength of his book is its seamless narrative of history, which uncovers the truth behind the legends. A mass of solidly researched fact, not readily found elsewhere, is seasoned with lively, humorous and occassionally gruesome anecdote. The result, providing at once an invaluable sourcebook for the specialist and an enthralling narrative for the general reader, is by far the most comprehensive and accessible history of England versus invasion ever published.
The Defense Industrial Base: Strategies for a Changing World
by Nayantara HenselThe US and international defense industrial sectors have faced many challenges over the last twenty years, including cycles of growth and shrinkage in defense budgets, shifts in strategic defense priorities, and macroeconomic volatility. In the current environment, the defense sector faces a combination of these challenges and must struggle with the need to maintain critical aspects of the defense industrial base as defense priorities change and as defense budgets reduce or plateau. Moreover, the defense sector in the US is interconnected both with defense sectors in other countries and with other industry sectors in the US and global economies. As a result, strategic decisions made in one defense sector impact the defense sectors of other countries, as well as other areas of the economy. Given her academic, corporate, and Department of Defense experience as a leading economist and policy-maker, Dr. Nayantara Hensel is perfectly positioned to examine the interrelationship between these forces both historically and in the current environment, and to assess the implications for the future global defense industrial base.
Defense Innovation Handbook: Guidelines, Strategies, and Techniques (Systems Innovation Book Series)
by Adedeji B. Badiru and Cassie B. BarlowInnovation is the lifeline of national development. This handbook is a collection of chapters that provide techniques and methodologies for achieving the transfer of defense-targeted science and technology development for general industrial applications. The handbook shows how to translate theory and ideas into practical applications. Experts from national defense institutions, government laboratories, business, and industry contributed chapters to this handbook. The handbook also serves as an archival guide for nations, communities, and businesses expecting to embark upon science and technology transfer to industry. Included are several domestic and international case examples of practical innovation. Since the dawn of history, nations have engrossed themselves in developing new tools, techniques, and methodologies to protect their geographical boundaries. From the crude implements used by prehistorical people to very modern technologies, the end game has been the same. That is, to protect the homeland. Even in times of peace, efforts must be made to develop new machinery, equipment, processes, and devices targeted for the protection of the nation. The emergence of organized nations and structured communities facilitated even more innovative techniques of national defense. Evolution, revolution, and innovation have defined human existence for millennia. From the Ice Age to the Stone Age, the Bronze Age, the Iron Age, and to the modern age, innovation, rudimentary as it may be in many cases, has determined how humans move from one stage to the next. This comprehensive handbook provides a clear guide on the nuances of initiating and actualizing innovation. Both the qualitative and quantitative aspects of innovation are covered in the handbook. Features: Uses a systems framework to zero in on science and technology transfer Focuses on leveraging technical developments in defense organizations for general societal applications Coalesces the transfer strategies collated from various sources and practical applications Represents a world-class diverse collection of science and technology development, utilization, and transfer Highlights a strategy for government, academia, and industry partnerships

Defense Modeling, Simulation, and Analysis: MEETING THE CHALLENGE
by National Research Council of the National AcademiesModeling, simulation, and analysis (MS&A) is a crucial tool for military affairs. MS&A is one of the announced pillars of a strategy for transforming the U.S. military. Yet changes in the enterprise of MS&A have not kept pace with the new demands arising from rapid changes in DOD processes and missions or with the rapid changes in the technology available to meet those demands. To help address those concerns, DOD asked the NRC to identify shortcomings in current practice of MS&A and suggest where and how they should be resolved. This report provides an assessment of the changing mission of DOD and environment in which it must operate, an identification of high-level opportunities for MS&A research to address the expanded mission, approaches for improving the interface between MS&A practitioners and decision makers, a discussion of training and continuing education of MS&A practitioners, and an examination of the need for coordinated military science research to support MS&A.

This report applies robust decision making (RDM) to the air-delivered munitions mix challenge. RDM is quantitative, decision support methodology designed to inform decisions under conditions of deep uncertainty and complexity. This proof-of-concept demonstration suggests that RDM could help defense planners make plans more robust to a wide range of hard-to-predict futures.
Defensive (anti-herbivory) Coloration in Land Plants
by Simcha Lev-YadunThis book presents visual plant defenses (camouflage, mimicry and aposematism via coloration, morphology and even movement) against herbivores. It is mainly an ideological monograph, a manifesto representing my current understanding on defensive plant coloration and related issues. The book is not the final word in anything, but rather the beginning of many things. It aims to establish visual anti-herbivory defense as an integral organ of botany, or plant science as it is commonly called today. I think that like in animals, many types of plant coloration can be explained by selection associated with the sensory/cognitive systems of herbivores and predators to reduce herbivory. It is intended to intrigue and stimulate students of botany/plant science and plant/animal interactions for a very long time. This book is tailored to a readership of biologists and naturalists of all kinds and levels, and more specifically for botanists, ecologists, evolutionists and to those interested in plant/animal interactions. It is written from the point of view of a naturalist, ecologist and evolutionary biologist that I hold, considering natural selection as the main although not the only drive for evolution. According to this perspective, factors such as chance, founder effects, genetic drift and various stochastic processes that may and do influence characters found in specific genotypes, are not comparable in their power and influence to the common outcomes of natural selection, especially manifested when very many species belonging to different plant families, with very different and separate evolutionary histories, arrive at the same adaptation, something that characterizes many of the visual patterns and proposed adaptations described and discussed in this book. Many of the discussed visual defensive mechanisms are aimed at operating before the plants are damaged, i. e. , to be their first line of defense. In this respect, I think that the name of the book by Ruxton et al. (2004) "Avoiding Attack" is an excellent phrase for the assembly of the best types of defensive tactics. While discussing anti-herbivory, I do remember, study and teach physiological/developmental aspects of some of the discussed coloration patterns, and I am fully aware of the simultaneous and diverse functions of many plant characters in addition to defense.
Defiant: The Untold Story of the Battle of Britain
by Robert Verkaik'Defiant is both a stirring testament to the courage of the men who flew them and a welcome new examination of one of the Second World War's most famous conflicts'Alexander Larman, ObserverIn this startling new perspective on the Battle of Britain, Robert Verkaik reveals the surprising truth about the battle's forgotten fighter, the Boulton Paul Defiant.The crucial role played by the Spitfire and the Hurricane has been exhaustively recorded, but, to date, next to nothing has been written about the third British fighter which took part in the battle. By writing from the unique perspective of the pilots who flew the Defiant and their air-gunners, Verkaik helps to set the record straight. The Air Staff regarded the Defiant as a state-of-the-art bomber destroyer and wanted to equip a third of all Fighter Command squadrons with this new plane. But the head of Fighter Command, Hugh Dowding, had other ideas and went to war with Whitehall over its plan to saddle him with hundreds of 'obsolete' turret fighters. Then at Dunkirk, a Defiant squadron scored a huge success against the Luftwaffe by shooting down more German planes in one day than any other RAF unit before or since. Fighter Command, enthusiastically urged on by the Air Ministry, now committed its third fighter to the coming air battle over southern England. In the desperate dogfights of the battle, Defiants shot down both German bombers and fighters but suffered heavy losses too - one squadron was almost wiped out when it was ambushed by a superior force of Messerschmitt 109s. On 30 August 1940 all Defiant squadrons were withdrawn from the front line. The families of the Defiant air crews believed that their husbands, brothers and sons had died in vain, but the truth is that their vital contribution to the battle over Dunkirk and their role in the Battle of Britain has been all but erased from the official history. The story of the Defiant has not been allowed to mar the glorious victory won by the Spitfire and the Hurricane.But Verkaik has uncovered new records, including top-secret memos written by Hugh Dowding and his deputy Keith Park as well as correspondence with the Air Staff, combat and squadron reports, pilot logs and recordings of the last interviews with Defiant crews. He has also succeeded in tracing relatives of Defiant pilots and gunners to tell the story of the Battle of Britain as it has never been told before. He reveals how the myths which have grown up around the Defiant mask some inconvenient truths.
Deficit Irrigation: A Remedy for Water Scarcity
by Samiha Ouda Tahany Noreldin Abd El-Hafeez ZohryThis book focuses on proving that deficit irrigation could play an important role in increasing food production in times of water scarcity. Although the application of deficit irrigation can involve loss in crop productivity, it still secures water to be use in cultivating more lands and producing more food. The following questions are discussed and the authors offer solutions to these problems:Will the production, on a national level, resulting from these new added areas compensate yield losses attained by application of deficit irrigation?Is it possible to use deficit irrigation practice to reduce the applied irrigation water to certain crops that have a surplus in their production, and direct this saved water to cultivate new areas with crops have low self-sufficiency ratios? Under climate change in 2030, would deficit irrigation practice have the same role it plays under the current conditions? This book will appeal to students and researchers involved with water scarcity and food security.
