Dressed Photons

by Motoichi Ohtsu

Authored by the developer of dressed photon science and technology as well as nanophotonics, this book outlines concepts of the subject using a novel theoretical framework that differs from conventional wave optics. It provides a quantum theoretical description of optical near fields and related problems that puts matter excitation such as electronic and vibrational ones on an equal footing with photons. By this description, optical near fields are interpreted as quasi-particles and named dressed photons which carry the material excitation energy in a nanometric space. The author then explores novel nanophotonic devices, fabrications, and energy conversion based on the theoretical picture of dressed photons. Further, this book looks at how the assembly of nanophotonic devices produces information and communication systems. Dressed photon science and technology is on its way to revolutionizing various applications in devices, fabrications, and systems. Promoting further exploration in the field, this book presents physically intuitive concepts, theories, and technical details for students, engineers, and scientists engaged in research and development in dressed photon science and technology as well as nanophotonics.

Dressed Photons to Revolutionize Modern Physics: Exploring Longitudinal Electromagnetic Waves and Off-Shell Quantum Fields (Nano-Optics and Nanophotonics)

by Motoichi Ohtsu Hirofumi Sakuma

This book presents an in-depth review of the recent interdisciplinary studies that have shed light on the mechanisms of the creation, energy transfer, and measurement of the dressed photon. A dressed photon is a type of photon that results from the interaction between light and matter in a confined space, typically on the scale of nanometers. It has been applied to nano-fabrication technologies, energy conversion technologies, and silicon light-emitting devices. Despite its extensive applications in various fields, the dressed photon's off-shell nature has posed challenges in describing it through conventional optical scientific theories. The book explains how, through a mathematical viewpoint, the underlying spatiotemporal vortex dynamics connect the dressed photon, the dark energy field, and the structure of the universe. The canonical equations of motion, which describe the time evolution of dynamical systems with Hamiltonian structure, play a key role in understanding these physical phenomena. In particular, the covariant form of equations of motion, where vortex tensors explicitly appear, corresponds to the transformed canonical equations of motion in the Eulerian representation. This newly augmented view of the equations of motion presents a deeper understanding of the interconnectedness of different physical phenomena, which can enlighten graduate students, junior scientists, and industry engineers engaged or interested in this field.

Drift, Deformation, and Fracture of Sea Ice

by Jérôme Weiss

Sea ice is a major component of polar environments, especially in the Arctic where it covers the entire Arctic Ocean throughout most of the year. However, in the context of climate change, the Arctic sea ice cover has been declining significantly over the last decades, either in terms of its concentration or thickness. The sea ice cover evolution and climate change are strongly coupled through the albedo positive feedback, thus possibly explaining the Arctic amplification of climate warming. In addition to thermodynamics, sea ice kinematics (drift, deformation) appears as an essential factor in the evolution of the ice cover through a reduction of the average ice age (and consequently of the cover's thickness), or ice export out of the Arctic. This is a first motivation for a better understanding of the kinematical and mechanical processes of sea ice. A more upstream, theoretical motivation is a better understanding of the brittle deformation of geophysical objects across a wide range of scales. Indeed, owing to its very strong kinematics, compared e.g. to the Earth's crust, an unrivaled kinematical data set is available for sea ice from in situ (e.g. drifting buoys) or satellite observations. Here, we review the recent advances in the understanding of sea ice drift, deformation and fracturing obtained from these data. We focus particularly on the scaling properties in time and scale that characterize these processes, and we emphasize the analogies that can be drawn from the deformation of the Earth's crust. These scaling properties, which are the signature of long-range elastic interactions within the cover, constrain future developments in the modeling of sea ice mechanics. We also show that kinematical and rheological variables such as average velocity, average strain-rate or strength have significantly changed over the last decades, accompanying and actually accelerating the Arctic sea ice decline.

Drilling Down

by Joseph A. Tainter Tadeusz W. Patzek

For more than a century, oil has been the engine of growth for a society that delivers an unprecedented standard of living to many. We now take for granted that economic growth is good, necessary, and even inevitable, but also feel a sense of unease about the simultaneous growth of complexity in the processes and institutions that generate and manage that growth. As societies grow more complex through the bounty of cheap energy, they also confront problems that seem to increase in number and severity. In this era of fossil fuels, cheap energy and increasing complexity have been in a mutually-reinforcing spiral. The more energy we have and the more problems our societies confront, the more we grow complex and require still more energy. How did our demand for energy, our technological prowess, the resulting need for complex problem solving, and the end of easy oil conspire to make the Deepwater Horizon oil spill increasingly likely, if not inevitable? This book explains the real causal factors leading up to the worst environmental catastrophe in U.S. history, a disaster from which it will take decades to recover.

Drinking Water Distribution Systems: Assessing And Reducing Risks

by Committee on Public Water Supply Distribution Systems: Assessing Reducing Risks

Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems -- consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances -- carry drinking water from a centralized treatment plant or well supplies to consumers’ taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

Drinking Water Minerals and Mineral Balance: Importance, Health Significance, Safety Precautions

by Ingegerd Rosborg Frantisek Kozisek

Following the successful first edition of this book on drinking water quality and health, this new edition puts more focus on the importance of minerals in drinking water. It includes new scientific material and presents additional studies on the negative health effects of reverse osmosis water. The various safety organizations working on drinking water all warn about unhealthy constituents, as well as elements that can cause corrosion or scaling on pipes and installations. However, drinking water may also provide a substantial portion of the daily mineral intake, especially for the elderly and children, or those at risk of deficiencies due to unhealthy eating habits or starvation. Thus, a holistic approach to drinking water is presented in this book and the scope is extended from standards for undesirable substances to the basic mineral composition of water, examining 22 nutrient elements and ions and 21 toxic substances. The function of the nutrients in the body, symptoms of deficiency and overload, and advantages of the minerals from drinking water are presented, as well as symptoms of toxic elements from drinking water. The authors also suggest healthy ranges of minerals and mineral ratios for drinking water. The book offers a valuable resource for the health evaluation of drinking waters, for private well owners, public water producers and safety organizations alike.

Drinking Water Security in Rural India: Dynamics, Influencing Factors, and Improvement Strategy (Water Resources Development and Management)

by Nitin Bassi M. Dinesh Kumar Saurabh Kumar

This book highlights the multi-pronged strategy for achieving sustainable rural domestic water supply in India. It deepens the understanding of groundwater (predominant source of water supply) behaviour in response to natural processes in different geological settings, analyses the factors influencing the performance of water supply schemes; identifies the conditions under which groundwater-based drinking water sources become sustainable, suggests measures for improving the sustainability of drinking water wells in hard rock regions (covering 2/3rd of India’s geographical area), presents a decision-making framework for planning rural water supply schemes in the country for ensuring long-term sustainability, and suggests physical strategies and policy measures for achieving them.The analyses for development and validation of various models that explain groundwater system behaviour and performance of rural water supply schemes are undertaken for different geological settings in Maharashtra, as the state represents a microcosm of the various hydrological, topographical, and geohydrological conditions encountered in the country. The final analysis for proposing nation-wide strategies considers the various hydrological, geological, geohydrological, and topographical and climatic settings and groundwater contamination and pollution in the country.

Drinking Water Treatment

by Ravi Jain Chittaranjan Ray

Sustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses. Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to "democratize" membrane filtration have been presented. Riverbank filtration is a "natural" filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.

Drinking Water in Sicily: Hydrogeological and Hydrogeochemical Aspects

by Esterina Gagliano Candela Giovannella Pecoraino Sabina Morici Leonardo La Pica

This book consists of the hydrogeochemical study of the springs of the Sicilian territory used for drinking water purposes. One of the most important issues in the environmental field is the protection of water resources and in particular the safeguarding of water intended for drinking water use. Water resources need a careful prevention of pollution starting from multidisciplinary studies (geology, hydrogeology, geochemistry, geophysics) to understand the territory in order to highlight vulnerable areas and then plan, where necessary, monitoring activities for the control and protection of the resource. The reference is the Piano Regolatore degli Acquedotti (PRGA) of Sicily, Italy (updated in November 2010), which lists all the springs, subdivided by province (a total of 1014), currently used to supply water to Sicilian aqueducts. With regard to the geochemical part, the studies carried out by the INGV, Sezione di Palermo, for the Water Protection Plan for Sicily (2004-2005) were used as basic data. The study of the chemical characteristics of groundwater is of fundamental importance from a hydrogeological point of view as it allows the origin of the water and its evolution to be reconstructed. Springs as a groundwater resource are of considerable importance in relation to the availability of water resources due to the general decrease in precipitation. In the first part of the book all the existing data (flow rates, geochemical parameters, water quality, etc.) are collected and subsequently transferred to GIS software, after appropriate evaluations on the validity of the acquired data. Considering that the subject is quite delicate and involves various aspects (compliance with regulations, vulnerability of groundwater, anthropogenic pollution, etc.), carrying out a purely scientific study allows groundwater to be placed in a broader context than that of legislation aimed exclusively at compliance with the regulations in force.
