Diffusionics: Diffusion Process Controlled by Diffusion Metamaterials
by Fu-Bao Yang Ji-Ping HuangThis open access book presents a comprehensive exploration of diffusion metamaterials that control energy and mass diffusion. Currently, if from the perspective of governing equations, diffusion metamaterials and wave metamaterials (pioneered by J. B. Pendry in the 1990s) are recognised as the two most prominent branches in the field of metamaterials. These two branches differ in their emphasis on the diffusion equation (as the governing equation) and time-dependent characteristic lengths in diffusion metamaterials, as opposed to the wave equation (as the governing equation) and time-independent characteristic lengths in wave metamaterials. Organized into three distinct parts – 'Thermal Diffusion Metamaterials', 'Particle Diffusion Metamaterials', and 'Plasma Diffusion Metamaterials' – this book offers a rigorous exploration spanning physics, engineering, and materials science, aimed at advancing our understanding of diffusion processes controlled by diffusion metamaterials. Incorporating foundational theory, computational simulations, and laboratory experiments, the book equips researchers and scholars across these disciplines with comprehensive methods, insights, and results pivotal to the advancement of diffusion control. Beyond facilitating interdisciplinary discourse, the book serves as a catalyst for innovative breakthroughs at the crossroads of physics, thermodynamics, and materials science. Essentially, readers will acquire profound insights that empower them to spearhead advancements in diffusion science (diffusionics) and the engineering of metamaterials.

Digenetic Trematodes
by Rafael Toledo Bernard FriedDigenetic trematodes constitute a major helminth group that parasitize humans and animals, and are a major cause of morbidity and mortality. The diseases caused by trematodes have been neglected for years, especially as compared with other parasitic diseases. However, the geographical limits and the populations at risk are currently expanding and changing in relation to factors such as growing international markets, improved transportation systems, and demographic changes. This has led to a growing international interest in trematode infections, although factors such as the difficulties entailed in the diagnosis, the complexity of human and agricultural practices, the lack of assessments of the economic costs or the limited number of effective drugs are preventing the development of control measures of these diseases in humans and livestock. In-depth studies are needed to clarify the current epidemiology of these helminth infections and to identify new and specific targets for both effective diagnosis and treatments. The main goal of this book is to present the major trematodes and their corresponding diseases in the framework of modern parasitology, considering matters such as the application of novel techniques and analysis of data in the context of host-parasite interactions and to show applications of new techniques and concepts for the studies on digenetic trematodes. This is an ideal book for parasitologists, microbiologists, zoologists, immunologists, professional of public health workers, clinicians and graduate and post-graduate students.

Digenetic Trematodes of Indian Marine Fishes
by Rokkam Madhavi Rodney A. BrayThis book is the first to explore in detail the systematics and taxonomy of the digenean fauna of fish in Indian marine waters. It includes morphological descriptions of 648 species in 190 genera and 30 families. The figures from the original publications are enhanced and made more attractive. Each description is accompanied by information on hosts and distribution. Digenetic trematodes, usually known as Digeneans, are the most diverse group of metazoan parasites of marine fishes. They are parasitic flatworms (Phylum Platyhelminthes) with a complex life-cycle and as adults inhabit mainly the alimentary system and associated organs, but also occur in the blood, under the scales, in the body cavity and in the gall and urinary bladders. Keys to families, genera and species are provided, except for a few large and controversial genera, where morphological characters are insufficient for identification. Although there is extensive literature on Digeneans, it is scattered and largely in obscure local journals. Bringing together most of the primary literature on the subject, this book provides a primer for further study and a starting point for the use of modern molecular methods for the fauna of this region. Unique in its scope, it is a valuable resource for students, professional parasitologists and ecologists as well as fishery and wildlife biologists.
Digestible Quantum Field Theory
by Andrei SmilgaThis book gives an intermediate level treatment of quantum field theory, appropriate to a reader with a first degree in physics and a working knowledge of special relativity and quantum mechanics. It aims to give the reader some understanding of what QFT is all about, without delving deep into actual calculations of Feynman diagrams or similar. The author serves up a seven‐course menu, which begins with a brief introductory Aperitif. This is followed by the Hors d'oeuvres, which set the scene with a broad survey of the Universe, its theoretical description, and how the ideas of QFT developed during the last century. In the next course, the Art of Cooking, the author recaps on some basic facts of analytical mechanics, relativity, quantum mechanics and also presents some nutritious "extras" in mathematics (group theory at the elementary level) and in physics (theory of scattering). After these preparations, the reader should have a good appetite for the Entr#65533;es ‐ the central par t of the book where the Standard Model is described and explained. After Trou Normand, the restive pause including human stories about physicists and no formulas, the author serves the Dessert, devoted to supersymmetry (a very beautiful theory that is still awaiting a direct experimental confirmation), to general relativity and to the mystery of quantum gravity.

Digging for the Disappeared: Forensic Science after Atrocity
by Adam RosenblattThe mass graves from our long human history of genocide, massacres, and violent conflict form an underground map of atrocity that stretches across the planet's surface. In the past few decades, due to rapidly developing technologies and a powerful global human rights movement, the scientific study of those graves has become a standard facet of post-conflict international assistance. Digging for the Disappeared provides readers with a window into this growing but little-understood form of human rights work, including the dangers and sometimes unexpected complications that arise as evidence is gathered and the dead are named. Adam Rosenblatt examines the ethical, political, and historical foundations of the rapidly growing field of forensic investigation, from the graves of the "disappeared" in Latin America to genocides in Rwanda and the former Yugoslavia to post-Saddam Hussein Iraq. In the process, he illustrates how forensic teams strive to balance the needs of war crimes tribunals, transitional governments, and the families of the missing in post-conflict nations. Digging for the Disappeared draws on interviews with key players in the field to present a new way to analyze and value the work forensic experts do at mass graves, shifting the discussion from an exclusive focus on the rights of the living to a rigorous analysis of the care of the dead. Rosenblatt tackles these heady, hard topics in order to extend human rights scholarship into the realm of the dead and the limited but powerful forms of repair available for victims of atrocity.
Digging Up the Dead: A History of Notable American Reburials
by Michael G. KammenA funeral closes a life story, and a grave in a cemetery marks its end forever. But what happens when those left behind don't agree about the meaning of that story? Or when that disagreement extends all the way to arguments about the final resting place itself? In a surprising number of cases over the years, that's when people have chosen to grab shovels and start digging. With Digging Up the Dead, Pulitzer Prize-winning historian Michael Kammen reveals a treasure trove of fascinating, surprising, and sometimes gruesome stories of exhumation and reburial from throughout American history. Taking us to the contested grave sites of such figures as Sitting Bull, John Paul Jones, Frank Lloyd Wright, Daniel Boone, Jefferson Davis, and even Abraham Lincoln, Kammen explores how complicated interactions of regional pride, shifting reputations, and evolving burial practices led to public, often emotional battles over the final resting places of famous figures. Grave-robbing, skull-fondling, cases of mistaken identity, and the financial lures of cemetery tourism all come into play as Kammen delves deeply into this little-known- yet surprisingly persistent- aspect of American history. Simultaneously insightful and interesting, masterly and macabre, Digging Up the Dead reminds us that the stories of American history don't always end when the key players pass on. Rather, the battle- over reputations, interpretations, and, last but far from least, possession of the remains themselves- is often just beginning.
Digital Afterlife and the Spiritual Realm (Chapman & Hall/CRC Artificial Intelligence and Robotics Series)
by Maggi Savin-BadenFew religious leaders have examined the potential for the positive impact of digital media and digital immortality creation in religious contexts. It is evident that there have been recent moves away from traditional funeral services focusing on the transition of the deceased into the future world beyond, towards a rise of memorial content within funerals and commemorative events. This has heralded shifts in afterlife beliefs by replacing them, to all intents and purposes, by attitudes to this life. Digital Afterlife and the Spiritual Realm explores the ways in which digital media and digital afterlife creation affects social and religious understandings of death and the afterlife. Features Understands the impact of digital media on those living and those working with the bereaved Explores the impact of digital memorialisation post death Examines the ways in which digital media may be changing conceptions and theologies of death For many people, digital afterlife and the spiritual realm largely remains an area that is both inchoate and confusing. This book will begin to unravel some of this bafflement.

Digital Agriculture: A Solution for Sustainable Food and Nutritional Security
by P. M. Priyadarshan Shri Mohan Jain Suprasanna Penna Jameel M. Al-KhayriThe world population is increasing while arable land is decreasing at an alarming rate. About one-quarter of arable land is degraded and needs significant restoration before it can sustain crops again. By 2030, the water supply will fall 40% short of meeting global demand. Moreover, looming climate change poses additional challenge to increasing food production to feed 10 billion people by 2050. Current major agricultural systems are on a largely unsustainable trajectory because of their contributions to greenhouse gas emissions, water pollution, and biodiversity loss.For these reasons, innovative technologies are being introduced in modern agriculture to sustain food production. They include digital and geospatial technologies to manage soil, climate and plant genetic resources. With the development of tools and sensors integrated into the internet of things (IoT) environment, physically collected information is converted into computer-readable language. Digital innovations thus allow real-time analysis, machine learning, and artificial intelligence (AI) that manage massive amount of data, also known as big data. Accordingly, digital agriculture affords greater potential for sustainable farming and economic benefits. This book summarizes the latest advances in AI-integration of agriculture practices. Specific focus includes but not limited to, big data, yield mapping, pests management, and optimal fertigation. As such, it presents a forward-looking approach to meet multiple UN Sustainable Development Goals, specifically, SDG 2, 6, 13 and 15.
