Deepfakes: The Coming Infocalypse
by Nina SchickEverything you need to know about "deepfakes" and what could become the biggest information and communications meltdown in world history.In a world of deepfakes, it will soon be impossible to tell what is real and what isn't. As advances in artificial intelligence, video creation, and online trolling continue, deepfakes pose not only a real threat to democracy -- they threaten to take voter manipulation to unprecedented new heights. This crisis of misinformation which we now face has since been dubbed the "Infocalypse."In DEEPFAKES, investigative journalist Nina Schick uses her expertise from working in the field to reveal shocking examples of deepfakery and explain the dangerous political consequences of the Infocalypse, both in terms of national security and what it means for public trust in politics. This all-too-timely book also unveils what this all means for us as individuals, how deepfakes will be used to intimidate and to silence, for revenge and fraud, and just how truly unprepared governments and tech companies are for what's coming.
Deepwater Alchemy: Extractive Mediation and the Taming of the Seafloor
by Lisa Yin HanHow underwater mediation has transformed deep-sea spaces into resource-rich frontiers Green energy technologies such as windmills, solar panels, and electric vehicles may soon depend on material found at the seabed. How did a space once imagined to be empty and unfathomable come to be thought of as a treasure trove of resources? Lisa Yin Han traces how contemporary developments in underwater sensing and imaging materially and imaginatively transmogrify the ocean bottom into a resource frontier capable of sustaining a digitally connected global future. Set against the backdrop of climate change, energy transition, and the expansion of industrial offshore extractions, Deepwater Alchemy looks at oceanic media and its representation of the seabed in terms of valuable resources. From high-tech simulations to laboratories and archives that collect and analyze sediments, Han explores the media technologies that survey, visualize, and condition the possibility for industrial resource extraction, introducing the concept of extractive mediation to describe the conflations between resource prospecting and undersea knowledge production. Moving away from anthropocentric frameworks, she argues that we must equalize access to deep ocean mediation and include the submerged perspectives of multispecies communities. From the proliferation of petroleum seismology to environmental-impact research on seabed mining to the development of internet-enabled seafloor observatories, Deepwater Alchemy shows us that deepwater mediation is entangled in existential hopes and fears for our planetary future. As the ocean bottom becomes increasingly accessible to people, Han prompts us to ask not whether we can tame the seafloor, but, rather, why and for whom are we taming it?

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 Beef: The Ecological and Nutritional Case for Meat, 2nd Edition
by Nicolette Hahn Niman“Nicolette Hahn Niman sets out to debunk just about everything you think you know . . . She’s not trying to change your mind; she’s trying to save your world.”—Los Angeles Times “Elegant, strongly argued.”—The Atlantic (named a “Best Food Book”) As the meat industry—from small-scale ranchers and butchers to sprawling slaughterhouse operators—responds to COVID-19, the climate threat, and the rise of plant-based meats, Defending Beef delivers a passionate argument for responsible meat production and consumption–in an updated and expanded new edition. For decades it has been nearly universal dogma among environmentalists that many forms of livestock—goats, sheep, and others, but especially cattle—are Public Enemy Number One. They erode soils, pollute air and water, damage riparian areas, and decimate wildlife populations. As recently as 2019, a widely circulated Green New Deal fact sheet even highlighted the problem of “farting cows.” But is the matter really so clear-cut? Hardly. In Defending Beef, Second Edition, environmental lawyer turned rancher Nicolette Hahn Niman argues that cattle are not inherently bad for the earth. The impact of grazing can be either negative or positive, depending on how livestock are managed. In fact, with proper oversight, livestock can play an essential role in maintaining grassland ecosystems by performing the same functions as the natural herbivores that once roamed and grazed there. With more public discussions and media being paid to connections between health and diet, food and climate, and climate and farming—especially cattle farming, Defending Beef has never been more timely. And in this newly revised and updated edition, the author also addresses the explosion in popularity of “fake meat” (both highly processed “plant-based foods” and meat grown from cells in a lab, rather than on the hoof). Defending Beef is simultaneously a book about big issues and the personal journey of the author, who continues to fight for animal welfare and good science. Hahn Niman shows how dispersed, grass-based, smaller-scale farms can and should become the basis of American food production.
