Defense Resource Planning Under Uncertainty
by Jonathan Klenk Kate Giglio Robert J. Lempert Drake Warren Robert W. Button Ryan HenryDefense planning faces significant uncertainties. 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.

A Definitive Guide to Behavioural Safety: The Definitive Guide
by Tim MarshThis book makes the case that far too much work undertaken under the banner of ‘behavioural safety’ is overly person-focused. ‘If you can walk on hot coals, you can do anything – so be safe’ needs to be dismissed out of hand, but also more advanced techniques based on coaching and empowerment fail to reflect the fact that, as ‘Just Culture’ models show, the great majority of causes of unsafe behaviour are environmental. Our methodologies mustn’t focus on the person with an open mind that there may be an underlying root cause; they must start from the statistically proven assumption that there is an underlying cause. This shift in mindset has a profound impact on the type of methodologies we must lead with, how they are used, how they are perceived, and last but certainly not least, their efficacy. A Definitive Guide to Behavioural Safety is a one-stop guide to all of the core theories and principles that underpin behaviour-based safety. All front-line behaviours that lead to incidents and injury are covered by the term behavioural safety, and getting to grips with the behaviours that might lead people to engage in unsafe or risky behaviour is crucial to prevention. In this book, internationally acclaimed behavioural safety expert Tim Marsh leads the reader through the three main strands: The awareness approach. The walk-and-talk approach. The Six Sigma safety or the Deming-inspired ‘full’ approach. Going through the very latest innovations in the field, the book covers the systemic approach to safety observation, measurement, intervention and analysis, but also incorporates emotional intelligence training aimed at enhancing supervisor–worker trust and communication more generally. A Definite Guide to Behavioural Safety is a perfect guide for any professional, whether you’re aiming to set up an ambitious and wide-ranging behavioural safety programme from scratch or you’re looking to refresh or extend an existing approach.
A Definitive Guide to Behavioural Safety: Health and Well-Being, Second Edition
by Tim Marsh‘Behavioural safety’ or behaviour-based safety (BBS) has been around as a concept for several decades and is commonly held to mean directly tackling the frontline behaviours that lead to incidents and injury. Unfortunately, virulent criticism of some approaches of BBS frequently generalises to all others, so that commentators don’t know if they are arguing or agreeing. This book aims to cut through the waffle to be the one-stop guide to all the core theories and principles that underpin behaviour-based safety. In this second edition, internationally acclaimed behavioural safety expert Tim Marsh leads the reader through the three main strands: The awareness approach, the ‘walk-and-talk’ approach, and the Six-Sigma safety or the Deming-inspired ‘full’ approach that covers the systemic approach to safety observation, measurement, intervention, and analysis, but also incorporates emotional intelligence training aimed at enhancing supervisor-worker trust and communication more generally. Updated to reflect systemic changes due to the COVID-19 pandemic and featuring a brand-new chapter on well-being that discusses the massive changes in thinking about the interaction of culture and personal safety that have occurred since the previous edition was published. This book allows the reader to set up an ambitious and wide-ranging behavioural safety programme from scratch or refresh their current approach. Written by one of the world’s leading BBS experts, including leading the first major research project on the applied use of BBS outside of the US, based on the author’s experiences with more than 400 organisations Delivered in an accessible and popular writing style that simplifies complex theory and arguments in a user-friendly way, plus features end-of-chapter checklists to underpin learning Possesses a post-COVID focus, bringing behavioural safety into the 2020s, and covers the growing concept of well-being in a brand-new chapter. The title features end-of-chapter checklists to confirm understanding of the concepts. A Definitive Guide to Behavioural Safety is the go-to book for any practicing occupational health and safety professional.
Deforestation: Social Dynamics in Watersheds and Mountain Ecosystems (Routledge Library Editions: Ecology #5)
by J. Ives D. C. PittOriginally published in 1988 Deforestation examines deforestation as a major environmental and development problem. It examines the issues of forests being cut in tropical and mountain areas, and how acid rain, pollution and disease wreak havoc in temperate zones. Some of the worst effects of deforestation have been changes in the world’s climate system, erosion and flooding, desertification, wood short-ages and the disappearance of some floral and fauna species. This book challenges the belief that deforestation is due to entirely rapid population growth and agricultural expansion and emphasises the effects of commercial exploitation and poor planning and management. In concludes with a programme for reforestation using agro-forestry, appropriate cottage industries, improved international programmes, local land reforms and community participation.

Deformation and Flow of Polymeric Materials
by Helmut Münstedt Friedrich Rudolf SchwarzlThis book describes the properties of single polymer molecules and polymeric materials and the methods how to characterize them. Molar masses, molar mass distributions and branching structure are discussed in detail. These properties are decisive for a deeper understanding of structure/properties relationships of polymeric materials. This book therefore describes and discusses them in detail. The mechanical behavior as a function of time and temperature is a key subject of the book. The authors present it on the basis of many original results they have obtained in their long research careers. They present the temperature dependence of mechanical properties of various polymeric materials in a wide temperature range: from cryogenic temperatures to the melt. Besides an extensive data collection on the transitions of various different polymeric materials, they also carefully present the physical explanations of the observed phenomena. Glass transition and melting temperatures are discussed, particularly, with their relevance for applications. A comprehensive part of the book deals with properties of polymers in the molten state and their decisive influence on the processing of the materials. The book presents and discusses viscous and elastic properties in detail as a function of molar mass, polydispersity, and branching. This book addresses students of polymer and materials science, as well as other natural sciences. Besides this educational value, it will also serve as a valuable monograph for everyone dealing with polymers and polymeric materials, from research, over development, to applications.

Deformation and Fracture of Solid-State Materials
by Sanichiro YoshidaThis volume introduces a comprehensive theory of deformation and fracture to engineers and applied scientists. Here "comprehensive" means that the theory can describe all stages of deformation from elastic to plastic and plastic to fracturing stage on the same basis (equations). The comprehensive approach is possible because the theory is based on a fundamental physical principle called the local symmetry, or gauge invariance, as opposed to phenomenology. Professor Yoshida explains the gist of local symmetry (gauge invariance) intuitively so that engineers and applied physicists can digest it easily, rather than describing physical or mathematical details of the principle. The author also describes applications of the theory to practical engineering, such as nondestructive testing in particular, with the use of an optical interferometric technique called ESPI (Electronic Speckle-Pattern Interferometry). The book is not a manual of applications. Instead, it provides information on how to apply physical concepts to engineering applications.
Deformation Compatibility Control for Engineering Structures
by Hanhua Zhu Zhihui Zhou Mengchong Chen Jianliang DengThis book presents essential methods of deformation compatibility control, and explicitly addresses the implied conditions on the methods' deformation compatibility. Consequently, these conditions can be considered in engineering structure design, while the conditions on stable equilibrium can be taken into account in the design method. Thus, the designed deformation and the actual deformation of the respective structure are approximately identical, guaranteeing both the flexibility of the construction material in force transmission and the equilibrium of force in the structure. Though equilibrium theory in engineering structures has been extensively studied, there has been comparatively little research on compatibility. In the limited researches available, the topics are primarily the theories and assumptions on the deformation compatibility, while few systematic works focus on the mechanical theoretical principles and methods of deformation compatibility control. As such, the flexibility of the construction material in force transmission and the stable equilibrium of the structure as a whole cannot be guaranteed based on these research results. Successfully addressing this important gap in the literature, the book is intended for researchers and postgraduates in engineering mechanics, civil engineering and related areas.
Deformation of Three-layer Structural Elements in Thermal Radiation Fields
by Starovoitov Eduard Michael Zhuravkov Denis Leonenko Yongtao LyuThis book methodically details the formulations and approaches to solve boundary value problems, which are essential for determining the stress–strain states in three-layer rods and plates subjected to both single and quasi-static variable loads in thermal radiation and force fields. It duly considers the complex influences on the physically nonlinear properties of the materials in each layer. The book offers several innovative analytical solutions and a numerical parametric analysis of the stress–strain scenarios in these structures. It describes the deformation of physically nonlinear media in thermoradiational fields within the small elastic-plastic deformations theory framework. The work explores variational problem-solving methods and the elastic solution method. It presents a formula for calculating the temperature within a three-layer assembly, derived by averaging the thermophysical properties of the materials across the layers' thickness. Additionally, the book includes an analysis of the attenuation of neutron flux as it passes through a three-layer element.

Defying Limits: Lessons from the Edge of the Universe
by Dave WilliamsAn inspirational, uplifting, and life-affirming memoir about passion, resilience and living life to the fullest, from Dr. Dave Williams, one of Canada’s most accomplished astronauts.I had dreamt about becoming an astronaut from the time I watched Alan Shepard launch on the first American sub-orbital flight on May 5, 1961. Eleven days before my seventh birthday, I committed to a new goal: one day, I would fly in outer space. Dr. Dave has led the sort of life that most people only dream of. He has set records for spacewalking. He has lived undersea for weeks at a time. He has saved lives as an emergency doctor, launched into the stratosphere twice, and performed surgery in zero gravity. But if you ask him how he became so accomplished, he’ll say: “I’m just a curious kid from Saskatchewan.” Curious indeed. Dr. Dave never lost his desire to explore nor his fascination with the world. Whether he was exploring the woods behind his childhood home or floating in space at the end of the Canadarm, Dave tried to see every moment of his life as filled with beauty and meaning. He learned to scuba dive at only twelve years old, became a doctor despite academic struggles as an undergraduate, and overcame stiff odds and fierce competition to join the ranks of the astronauts he had idolized as a child. There were setbacks and challenges along the way—the loss of friends in the Columbia disaster, a cancer diagnosis that nearly prevented him from returning to space—but through it all, Dave never lost sight of his goal. And when he finally had the chance to fly among the stars, he came to realize that although the destination can be spectacular, it’s the journey that truly matters. In Defying Limits, Dave shares the events that have defined his life, showing us that whether we’re gravity-defying astronauts or earth-bound terrestrials, we can all live an infinite, fulfilled life by relishing the value and importance of each moment. The greatest fear that we all face is not the fear of dying, but the fear of never having lived. Each of us is greater than we believe. And, together, we can exceed our limits to soar farther and higher than we ever imagined.
Defying Reality: The Inside Story of the Virtual Reality Revolution
by David M. EwaltA fascinating exploration of the history, development, and future of virtual reality, a technology with world-changing potential, written by award-winning journalist and author David Ewalt, stemming from his 2015 Forbes cover story about the Oculus Rift and its creator Palmer Luckey.You’ve heard about virtual reality, seen the new gadgets, and read about how VR will be the next big thing. But you probably haven’t yet realized the extent to which this technology will change the way we live. We used to be bound to a physical reality, but new immersive computer simulations allow us to escape our homes and bodies. Suddenly anyone can see what it’s like to stand on the peak of Mount Everest. A person who can’t walk can experience a marathon from the perspective of an Olympic champion. And why stop there? Become a dragon and fly through the universe. But it’s not only about spectacle. Virtual and augmented reality will impact nearly every aspect of our lives—commerce, medicine, politics—the applications are infinite. It may sound like science fiction, but this vision of the future drives billions of dollars in business and is a top priority for such companies as Facebook, Google, and Sony. Yet little is known about the history of these technologies. In Defying Reality, David M. Ewalt traces the story from ancient amphitheaters to Cold War military laboratories, through decades of hype and failure, to a nineteen-year-old video game aficionado who made the impossible possible. Ewalt looks at how businesses are already using this tech to revolutionize the world around us, and what we can expect in the future. Writing for a mainstream audience as well as for technology enthusiasts, Ewalt offers a unique perspective on VR. With firsthand accounts and on-the-ground reporting, Defying Reality shows how virtual reality will change our work, our play, and the way we relate to one another.
