Non-fickian Solute Transport in Porous Media
by Don KulasiriThe advection-dispersion equation that is used to model the solute transport in a porous medium is based on the premise that the fluctuating components of the flow velocity, hence the fluxes, due to a porous matrix can be assumed to obey a relationship similar to Fick's law. This introduces phenomenological coefficients which are dependent on the scale of the experiments. This book presents an approach, based on sound theories of stochastic calculus and differential equations, which removes this basic premise. This leads to a multiscale theory with scale independent coefficients. This book illustrates this outcome with available data at different scales, from experimental laboratory scales to regional scales.

Non-Fourier Heat Conduction: From Phase-Lag Models to Relativistic and Quantum Transport
by Alexander I. ZhmakinThis book presents a broad and well-structured overview of various non-Fourier heat conduction models. The classical Fourier heat conduction model is valid for most macroscopic problems. However, it fails when the wave nature of the heat propagation becomes dominant and memory or non-local spatial effects become significant; e.g., during ultrafast heating, heat transfer at the nanoscale, in granular and porous materials, at extremely high values of the heat flux, or in heat transfer in biological tissues. The book looks at numerous non-Fourier heat conduction models that incorporate time non-locality for materials with memory, such as hereditary materials, including fractional hereditary materials, and/or spatial non-locality, i.e. materials with a non-homogeneous inner structure. Beginning with an introduction to classical transport theory, including phase-lag, phonon, and thermomass models, the book then looks at various aspects of relativistic and quantum transport, including approaches based on the Landauer formalism as well as the Green-Kubo theory of linear response. Featuring an appendix that provides an introduction to methods in fractional calculus, this book is a valuable resource for any researcher interested in theoretical and numerical aspects of complex, non-trivial heat conduction problems.
Non-Governmental Organizations and Development
by David Lewis Nazneen KanjiNon-governmental organizations (NGOs) are high profile actors in the field of international development, both as providers of services to vulnerable individuals and communities and as campaigning policy advocates. This book provides a critical introduction to the wide-ranging topic of NGOs and development. Written by two authors with more than twenty years experience of research and practice in the field, the book combines a critical overview of the main research literature with a set of up-to-date theoretical and practical insights drawn from experience in Asia, Europe, Africa and elsewhere. It highlights the importance of NGOs in development, but it also engages fully with the criticisms that the increased profile of NGOs in development now attracts. Non-Governmental Organizations and Development begins with a discussion of the wide diversity of NGOs and their roles, and locates their recent rise to prominence within broader histories of struggle as well as within the ideological context of neo-liberalism. It then moves on to analyze how interest in NGOs has both reflected and informed wider theoretical trends and debates within development studies, before analyzing NGOs and their practices, using a broad range of short case studies of successful and unsuccessful interventions. David Lewis and Nazneen Kanji then moves on to describe the ways in which NGOs are increasingly important in relation to ideas and debates about ‘civil society’, globalization and the changing ideas and practices of international aid. The book argues that NGOs are now central to development theory and practice and are likely to remain important actors in development in the years to come. In order to appreciate the issues raised by their increasing diversity and complexity, the authors conclude that it is necessary to deploy a historically and theoretically informed perspective. This critical overview will be useful to students of development studies at undergraduate and masters levels, as well as to more general readers and practitioners. The format of the book includes figures, photographs and case studies as well as reader material in the form of summary points and questions. Despite the growing importance of the topic, no single short, up-to-date book exists that sets out the main issues in the form of a clearly written, academically-informed text: until now.
Non-Governmental Organizations and Development (Routledge Perspectives on Development)
by David Lewis Nazneen Kanji Nuno S. ThemudoThis book is an introduction to the wide-ranging topic of non-governmental organizations (NGOs) and development, combining a critical overview of the main research literature with a set of up-to-date theoretical and practical insights drawn from experience in Asia, Europe, Africa and elsewhere. The revised second edition highlights the continuing importance of NGOs in development, while fully engaging with the criticisms that their increased profile now attracts. It considers issues such as securitization, changing technologies, and recent concerns about safeguarding as well as going into more detail around topics such as market-based development and social enterprise. The diversity of NGOs and their roles is discussed against the broader historical background of struggles for social justice in different societies, as well as within the shifting ideological contexts of neoliberalism and populism. Using a broad range of short case studies of both successful and unsuccessful interventions, the authors analyze how interest in NGOs has both reflected and informed wider theoretical trends and debates within development studies. The book argues that NGOs are central to both development theory and practice and are likely to remain important actors for many years to come. This critical overview will be useful to students of development studies at undergraduate and master's levels in fields and disciplines as diverse as International Development Studies, International Relations, Geography, Anthropology, Global Studies, Politics and International Studies, as well as general readers and practitioners.

Non-Hermitian Hamiltonians in Quantum Physics
by Fabio Bagarello Roberto Passante Camillo TrapaniThis book presents the Proceedings of the 15th International Conference on Non-Hermitian Hamiltonians in Quantum Physics, held in Palermo, Italy, from 18 to 23 May 2015. Non-Hermitian operators, and non-Hermitian Hamiltonians in particular, have recently received considerable attention from both the mathematics and physics communities. There has been a growing interest in non-Hermitian Hamiltonians in quantum physics since the discovery that PT-symmetric Hamiltonians can have a real spectrum and thus a physical relevance. The main subjects considered in this book include: PT-symmetry in quantum physics, PT-optics, Spectral singularities and spectral techniques, Indefinite-metric theories, Open quantum systems, Krein space methods, and Biorthogonal systems and applications. The book also provides a summary of recent advances in pseudo-Hermitian Hamiltonians and PT-symmetric Hamiltonians, as well as their applications in quantum physics and in the theory of open quantum systems.
Non-Human Nature in World Politics: Theory and Practice (Frontiers in International Relations)
by André Saramago Joana Castro PereiraThis book explores the interconnections between world politics and non-human nature to overcome the anthropocentric boundaries that characterize the field of international relations. By gathering contributions from various perspectives, ranging from post-humanism and ecological modernization, to new materialism and post-colonialism, it conceptualizes the embeddedness of world politics in non-human nature, and proposes a reorientation of political practice to better address the challenges posed by climate change and the deterioration of the Earth’s ecosystems. The book is divided into two main parts, the first of which addresses new ways of theoretically conceiving the relationship between non-human nature and world politics. In turn, the second presents empirical investigations into specific case studies, including studies on state actors and international organizations and bodies. Given its scope and the new perspectives it shares, this edited volume represents a uniquely valuable contribution to the field.

Non-invertible Symmetry in 4-Dimensional Z2 Lattice Gauge Theory (Springer Theses)
by Masataka KoideThis book provides a method for concretely constructing defects that represent non-invertible symmetries in four-dimensional lattice gauge theory. In terms of generalized symmetry, a symmetry is considered to be equivalent to a topological operator whose value does not change even if the shape is topologically transformed. Even for models that lack symmetry in the traditional sense and are difficult to analyze, it is possible to analyze them as long as a generalized symmetry exists. Therefore, generalized symmetry is important for the non-perturbative analysis of quantum field theory. Some topological operators have no group structure, and the corresponding symmetries are called non-invertible symmetries. Concrete examples of non-invertible symmetries in higher-dimensional theories were discovered around 2020, and they have been actively studied as a field of generalized symmetries since then. This book explains the non-invertible symmetry represented by the Kramers-Wannier-Wegner duality, which was found firstly in a four-dimensional theory, represented by three-dimensional defects. This book is intended for those with preliminary knowledge of quantum field theory and statistical mechanics.
Non-linear Data Analysis on the Sphere
by Gregor RossmanithThis work deals with the search for signatures of non-Gaussianities in the cosmic microwave background (CMB). Probing Gaussianity in the CMB addresses one of the key questions in modern cosmology because it allows us to discriminate between different models of inflation, and thus concerns a fundamental part of the standard cosmological model. The basic goal here is to adapt complementary methods stemming from the field of complexity science to CMB data analysis. Two key concepts, namely the method of surrogates and estimators for local scaling properties, are applied to CMB data analysis. All results show strong non-Gaussianities and pronounced asymmetries. The consistency of the full sky and cut sky results shows convincingly for the first time that the influence of the Galactic plane is not responsible for these deviations from Gaussianity and isotropy. The findings seriously call into question predictions of isotropic cosmologies based on the widely accepted single field slow roll inflation model.
Non-Market Valuation in South Asia: Bridging Theory and Practice in Environmental Economics (Routledge Explorations in Environmental Studies)
by Mohammad Younus BhatThis book provides a comprehensive exploration of the challenges and issues concerning the economic valuation of natural resources.The authors present methods and tools that can help in designing policies and frameworks for the sustainable use of natural resources. This is followed by an exploration of the use and non-use values provided by environmental resources, as well as reviewing the current environmental valuation techniques. Furthermore, the authors use meta-analysis to explore a range of South Asia–based case studies, including India and Bangladesh. Using this empirical evidence, they detail the various imperfections, challenges and prospects in the area of management and allocation of environmental resources, conservation of environmental biodiversity and sustainability. This book will serve as a useful reference for academics and analysts in developed and developing countries working in the areas of environmental economics, green economics and sustainable development.It is also intended to encourage practitioners and managers in industry to deepen and expand upon their theoretical and practical understanding of the prevailing challenges associated with enhancing ecosystem services, improved solid waste management and restoring biodiversity of environmental resources.
Non-Motorized Transport Integration into Urban Transport Planning in Africa (Transport and Society)
by Winnie V. Mitullah Marianne Vanderschuren Meleckidzedeck KhayesiWhat challenges do pedestrians and cyclists face in cities of the developing world? What opportunities do these cities have to provide for walking and cycling? Based on in-depth research conducted in Cape Town (South Africa), Dar es Salaam (Tanzania) and Nairobi (Kenya), this book explores these questions by presenting work on walking and cycling travel behaviour, the status of road safety in these cities, as well as an analysis of the infrastructure for walking and cycling, and the workings of the institutions responsible for planning for these modes. The book also presents case studies relating to particular opportunities and challenges, such as the development and evaluation of ‘walking bus’ interventions, and the opportunities micro-simulation of pedestrian interventions offers within a data-scarce environment. Non-motorized Transport Integration into Urban Transport Planning in Africa demonstrates that transport and urban planning remains situated in a logic of automobile-dependent transport planning and global city development. This logic of practice does not pay adequate attention to walking and cycling. It argues that a significant shift in both policy as well as political commitment is needed so as to prioritize walking and cycling as strategies for sustainable transport policy in urban Africa. This book will be a key text for practitioners and policy makers working in planning, transport policy and urban development in Africa, as well as students and scholars of African studies, development studies, urban geography, transport studies and sustainable development.
Non-perturbative Renormalization Group Approach to Some Out-of-Equilibrium Systems: Diffusive Epidemic Process and Fully Developed Turbulence (Springer Theses)
by Malo TarpinThis thesis presents the application of non-perturbative, or functional, renormalization group to study the physics of critical stationary states in systems out-of-equilibrium. Two different systems are thereby studied. The first system is the diffusive epidemic process, a stochastic process which models the propagation of an epidemic within a population. This model exhibits a phase transition peculiar to out-of-equilibrium, between a stationary state where the epidemic is extinct and one where it survives. The present study helps to clarify subtle issues about the underlying symmetries of this process and the possible universality classes of its phase transition. The second system is fully developed homogeneous isotropic and incompressible turbulence. The stationary state of this driven-dissipative system shows an energy cascade whose phenomenology is complex, with partial scale-invariance, intertwined with what is called intermittency. In this work, analytical expressions for the space-time dependence of multi-point correlation functions of the turbulent state in 2- and 3-D are derived. This result is noteworthy in that it does not rely on phenomenological input except from the Navier-Stokes equation and that it becomes exact in the physically relevant limit of large wave-numbers. The obtained correlation functions show how scale invariance is broken in a subtle way, related to intermittency corrections.
Non-Renewable Resource Issues
by Richard Sinding-Larsen Friedrich-W. WellmerAll the solid fuels fossil energy and mineral commodities we use come out of the Earth. Modern society is increasingly dependent on mineral and fossil energy sources. They differ in availability, cost of production, and geographical distribution. Even if solid fuels, fossil energy resources and mineral commodities are non-renewable, the extracted metals can to a large extent be recycled and used again and again. Although the stock of these secondary resources and their use increases, the world still needs and will continue to need primary mineral resources for the foreseeable future. Growing demands have begun to restrict availability of these resources. The Earth is not running out of critical mineral resources - at least for the near future - but the ability to explore and extract these resources is being restricted in many regions by competing land use, as well as political and environmental issues. Extraction of natural resources requires a clear focus on sustainable development, involving economic, environmental and socio-cultural aspects. Although we do not know what the most important resources will be in 100 years from now, we can be quite certain that society will still need energy and a wide range of raw materials. These resources will include oil and gas, coal, uranium, thorium, geothermal, metallic minerals, industrial and specialty minerals, including cement, raw materials, rare-earth elements. A global approach for assessing the magnitude and future availability of these resources is called for - an approach that, with appropriate international collaboration, was started within the triennium of the International Year of Planet Earth. Some global mineral resource assessments, involving inter-governmental collaboration, have already been initiated. The International Year of Planet Earth helped to focus attention on how the geosciences can generate prosperity locally and globally, as well as sustainability issues in both developed and developing countries.
Non-Renewable Resources and Disequilibrium Macrodynamics (Routledge Library Editions: Environmental and Natural Resource Economics)
by Robert MarksThis study, first published in 1979, continues by examining the question of whether a competitive economy can efficiently allocate a stock of non-renewable natural resources through time. Long-run analyses of competitive economies with such resources have concluded that, without perfect foresight or a complete set of future markets extending infinitely far into the future, there is no economic mechanism to guarantee that the initial price is set so that the economy converges to the socially desirable path of balanced growth. This title will be of interest to students of environmental and natural resource economics.
Non-representational Theory (Key Ideas in Geography)
by Paul SimpsonNon-representational Theory explores a range of ideas which have recently engaged geographers and have led to the development of an alternative approach to the conception, practice, and production of geographic knowledge. Non-representational Theory refers to a key body of work that has emerged in geography over the past two and a half decades that emphasizes the importance of practice, embodiment, materiality, and process to the ongoing formation of social life. This title offers the first sole-authored, accessible introduction to this work and its impact on geography. Without being prescriptive the text provides a general explanation of what Non-representational Theory is. This includes discussion of the disciplinary context it emerged from, the key ideas and themes that characterise work associated with Non-representational Theory, and the theoretical points of reference that inspires it. The book then explores a series of conjunctions of ‘Non-representational Theory and...’, taking an area of geographic enquiry and exploring the impact Non-representational Theory has had on how it is researched and understood. This includes the relationships between Non-representational Theory and Practice, Affect, Materiality, Landscape, Performance, and Methods. Critiques of Non-representational Theory are also broached, including reflections on issues on identity, power, and difference. The text draws together the work of a range of established and emerging scholars working on the development of non-representational theories, allowing scholars from geography and other disciplines to access and assess the animating potential of such work. This volume is essential reading for undergraduates and post-graduate students interested in the social, cultural, and political geographies of everyday living.
Non-self-adjoint Schrödinger Operator with a Periodic Potential
by Oktay VelievThis book gives a complete spectral analysis of the non-self-adjoint Schrödinger operator with a periodic complex-valued potential. Building from the investigation of the spectrum and spectral singularities and construction of the spectral expansion for the non-self-adjoint Schrödinger operator, the book features a complete spectral analysis of the Mathieu-Schrödinger operator and the Schrödinger operator with a parity-time (PT)-symmetric periodic optical potential. There currently exists no general spectral theorem for non-self-adjoint operators; the approaches in this book thus open up new possibilities for spectral analysis of some of the most important operators used in non-Hermitian quantum mechanics and optics. Featuring detailed proofs and a comprehensive treatment of the subject matter, the book is ideally suited for graduate students at the intersection of physics and mathematics.

Also a useful resource for recent and related trends, the book is appropriate as a graduate-level and/or PhD-level text for courses on quantum mechanics and mathematical models in physics.
Non-standard Problems in Basin Modelling
by Yurii GalushkinThis book details how the GALO system of basin modelling may be used in the analysis of actual, non-standard problems of geology. It begins by addressing the tectonic subsidence of sedimentary basins, and goes on to consider the problems of maturation of organic matter and hydrocarbon generation in the vicinity of intrusions and subtrappean sedimentary complexes. Lastly, the book discusses the formation of temperature and heat flow distributions with depth due to the sharp climate variations in the Quaternary, which was marked by repeated formation and degradation of permafrost. The book studies the application of the GALO basin modelling system to the three problems mentioned above. Employing the GALO system provides a unique opportunity to assess the amplitude and duration of the stretching and thermal activation of the basin lithosphere, and to study in detail the formation of a maturity aureole of organic matter in the basin's subtrappean sedimentary cover. This book offers a valuable resource for all graduate students and professionals interested in numerical modelling of the thermal evolution of sedimentary basins. It will also be of great interest to petroleum geologists engaged in oil and gas exploration in the trap provinces of the world. Lastly, it will benefit those students and geologists dealing with the thermal field of sedimentary blankets in actual and degraded permafrost areas.
