Genesis of Diamonds and Associated Phases (Springer Mineralogy)

by Yuriy A. Litvin

This book presents an overview of recent advances in our understanding of the genesis of diamonds and the associated phases. It is divided into three main parts, starting with an introduction to the analysis of diamond inclusions to infer the formation processes. In turn, the second part of the book presents high-pressure experimental studies in mantle diamond-parental mineral systems with representative multicomponent boundary compositions. The experimental syngenesis phase diagrams provided reveal the physicochemical mechanisms of diamond nucleation and substantiate the mantle-carbonatite concept of the genesis of diamonds and associated phases. Lastly, the book describes the genetic classification of diamond-hosted mineral inclusions and experimentally determined RE “mineral-parental melt” partition coefficients. The physicochemical experimental evidence presented shows the driving forces behind the fractional evolution of the mantle magmas and diamond-parental melts.Given the depth and breadth of its coverage, the book offers researchers essential new insights into the ways diamonds and associated minerals and rocks are naturally created.

Self-organized Criticality and Predictability in Atmospheric Flows: The Quantum World of Clouds and Rain (Springer Atmospheric Sciences)

by Amujuri Mary Selvam

This book presents a new concept of General Systems Theory and its application to atmospheric physics. It reveals that energy input into the atmospheric eddy continuum, whether natural or manmade, results in enhancement of fluctuations of all scales, manifested immediately in the intensification of high-frequency fluctuations such as the Quasi-Biennial Oscillation and the El-Nino–Southern Oscillation cycles. Atmospheric flows exhibit self-organised criticality, i.e. long-range correlations in space and time manifested as fractal geometry to the spatial pattern concomitant with an inverse power law form for fluctuations of meteorological parameters such as temperature, pressure etc. Traditional meteorological theory cannot satisfactorily explain the observed self-similar space time structure of atmospheric flows. A recently developed general systems theory for fractal space-time fluctuations shows that the larger-scale fluctuation can be visualised to emerge from the space-time averaging of enclosed small-scale fluctuations, thereby generating a hierarchy of self-similar fluctuations manifested as the observed eddy continuum in power spectral analyses of fractal fluctuations. The interconnected network of eddy circulations responds as a unified whole to local perturbations such as global-scale response to El-Nino events. The general systems theory model predicts an inverse power law form incorporating the golden mean τ for the distribution of space-time fluctuation patterns and for the power (variance) spectra of the fluctuations. Since the probability distributions of amplitude and variance are the same, atmospheric flows exhibit quantumlike chaos. Long-range correlations inherent to power law distributions of fluctuations are identified as nonlocal connection or entanglement exhibited by quantum systems such as electrons or photons. The predicted distribution is close to the Gaussian distribution for small-scale fluctuations, but exhibits a fat long tail for large-scale fluctuations. Universal inverse power law for fractal fluctuations rules out unambiguously linear secular trends in climate parameters.

Smart Cities in the Mediterranean: Coping with Sustainability Objectives in Small and Medium-sized Cities and Island Communities (Progress in IS)

by Anastasia Stratigea Elias Kyriakides Chrysses Nicolaides

This book sheds new light on the current and future challenges faced by cities, and presents approaches, options and solutions enabled by Information and Communication Technologies (ICT) in the smart city context. By focusing on sustainability objectives within a rapidly changing social, economic, environmental and technological setting, it explores a variety of planning challenges faced by contemporary cities and the power of smart city developments in terms of providing innovative tools, approaches, methodologies and technologies to help cities cope with these challenges. Key issues addressed include smart city (e-) planning and (e-)participation; smart data management to facilitate decision-making processes in cities and insular communities on a variety of topics; smart and sustainable management aspects of climate change, water scarcity, mobility, energy, infrastructure, tourism, blue growth, risk assessment; etc. The book presents current and potential pathways and applications for the evolution of smart cities and communities, taking into consideration the unique problems and opportunities emanating from their specific geographical location. The case study examples mainly concern small and medium-sized cities and communities as well as insular areas in the Mediterranean region, while also incorporating lessons learned from other parts of the world. Their focus is on the specific opportunities and threats emerging in these urban and insular environments, which are characterized by their role as globally known tourist destinations, their coastal or port character, and unique cultural resources, as well as the high rated vulnerability in very many sustainability respects (social, economic, biodiversity, urbanization, migration, poverty, etc.) to be found in the Mediterranean region at large

Modeling Coastal Hypoxia: Numerical Simulations of Patterns, Controls and Effects of Dissolved Oxygen Dynamics

by Dubravko Justic Kenneth A. Rose Robert D. Hetland Katja Fennel

This book provides a snapshot of representative modeling analyses of coastal hypoxia and its effects. Hypoxia refers to conditions in the water column where dissolved oxygen falls below levels that can support most metazoan marine life (i.e., 2 mg O2 l-1). The number of hypoxic zones has been increasing at an exponential rate since the 1960s; there are currently more than 600 documented hypoxic zones in the estuarine and coastal waters worldwide. Hypoxia develops as a synergistic product of many physical and biological factors that affect the balance of dissolved oxygen in seawater, including temperature, solar radiation, wind, freshwater discharge, nutrient supply, and the production and decay of organic matter. A number of modeling approaches have been increasingly used in hypoxia research, along with the more traditional observational and experimental studies. Modeling is necessary because of rapidly changing coastal circulation and stratification patterns that affect hypoxia, the large spatial extent over which hypoxia develops, and limitations on our capabilities to directly measure hypoxia over large spatial and temporal scales. This book consists of 15 chapters that are broadly organized around three main topics: (1) Modeling of the physical controls on hypoxia, (2) Modeling of biogeochemical controls and feedbacks, and, (3) Modeling of the ecological effects of hypoxia. The final chapter is a synthesis chapter that draws generalities from the earlier chapters, highlights strengths and weaknesses of the current state-of-the-art modeling, and offers recommendations on future directions.

From the Paris Agreement to a Low-Carbon Bretton Woods: Rationale for the Establishment of a Mitigation Alliance

by Michele Stua

This book investigates the existing and possible links between the concept of a Carbon Club and the Paris Agreement. In doing so the book defines those criteria that may lead to an effective establishment of a Carbon Club acting within the mandate of the Paris Agreement and identifies the key questions that such an option may help to tackle: Which low-carbon pathways are compatible with the new temperature targets set by the Paris Agreement? Can new entities like the Carbon Club have a decisive role in guaranteeing the alignment of the aggregate mitigating actions with the global objectives identified within the Paris Agreement? What role will be played by market and non-market approaches within the proposed framework? How can economic, social, and environmental sustainability be ensured during the implementation of the Agreement? How can justice and equity be encouraged between the Parties and all the involved actors as required by the Agreement? Which instruments can be designed and adopted to provide the expected degree of transparency for the new system? To respond to these questions the book adopts a holistic approach, able to emphasize the strong interrelations. The book discusses the opportunity to develop a Carbon Club within the Article 6 framework, and provides a feasible roadmap for its means of implementation, rules and governance structure. The final result is a feasible policy proposal that takes into account all the key issues introduced by the questions, and draws a roadmap towards a 'low-carbon Bretton Woods’.

Reviving the Dying Giant: Integrated Water Resource Management in the Zayandeh Rud Catchment, Iran

by Shahrooz Mohajeri Lena Horlemann

This book presents the results of an interdisciplinary research project that was set up to introduce Integrated Water Resources Management (IWRM) at the Zayandeh Rud, Central Iran’s most important river. As a result of climate change and a missing overall concept for sustainably managing water resources, the river has repeatedly dried up in recent years. Not only has water stress led to severe conflicts among the water using sectors and neighboring provinces, it also threatens important ecosystems in the region. Thus, the joint development of an IWRM concept for the Zayandeh Rud catchment was the main objective of the project. Comprehensive technological and non-technological measures – ranging from wastewater reuse to capacity development – were adjusted to local conditions and implemented in order to initiate an integrated, iterative IWRM process. The design of a technology-based Water Management Tool (WMT) served as the connective link to create trust, cooperation and coordination among the stakeholders and institutions.

Multifunctional Land-Use Systems for Managing the Nexus of Environmental Resources

by Lulu Zhang Kai Schwärzel

It offers extensive information on land policy, implementation and scientific evidence, and discusses the restoration of the degraded Loess Plateau environment, which that brings new challenges in the sustainable use of natural resources, in particular soil and water. It presents a transdisciplinary and up-to-date understanding of interlinkages and competition between different ecosystem services and illustrates benefit sharing among different users and stakeholders, land- management practitioners and local governments. It is a major contribution to the on-going debate on future land-development strategies and identifies areas where there is a need for more research. This book is a valuable resource for students, scientists and policy makers.

Smart Markets for Water Resources: A Manual for Implementation (Global Issues in Water Policy #12)

by John F. Raffensperger Mark W. Milke

Why is trade in wholesale water so rare, when markets can actively trade bread, tractors, and electricity? This book shows that water markets fail because of high transaction costs, resulting in inefficient allocations and unpredictable environmental effects. To overcome these obstacles, this book proposes a trading mechanism called a smart market. A smart market is an auction cleared with optimization. A smart market can reduce the transaction costs of water trading, while improving the environmental outcomes. The authors show why a smart market for water is needed, how it would work, and how to implement it. The smart market described here uses a hydrology simulation of the water resource, user bids via the internet, and mathematical optimization, to maximize the economic value of water while meeting all environmental constraints. The book provides the background to understand the smart market for water, and the detail to help the reader start working on its application. The book explores topics such as:Why water should be more expensive near sensitive environmental locations,Ways to set initial allocations of water rights,The role of regulatory oversight,The prerequisites of a water market, andHow to counter objections to water markets. The culmination of a decade of investigation, this book combines explanation, examples, and detail to inform policymakers, large water users, environmental organizations, researchers, and a thirsty public.

A Computational Non-commutative Geometry Program for Disordered Topological Insulators (SpringerBriefs in Mathematical Physics #23)

by Emil Prodan

This work presents a computational program based on the principles of non-commutative geometry and showcases several applications to topological insulators. Noncommutative geometry has been originally proposed by Jean Bellissard as a theoretical framework for the investigation of homogeneous condensed matter systems. Recently, this approach has been successfully applied to topological insulators, where it facilitated many rigorous results concerning the stability of the topological invariants against disorder.In the first part of the book the notion of a homogeneous material is introduced and the class of disordered crystals defined together with the classification table, which conjectures all topological phases from this class. The manuscript continues with a discussion of electrons’ dynamics in disordered crystals and the theory of topological invariants in the presence of strong disorder is briefly reviewed. It is shown how all this can be captured in the language of noncommutative geometry using the concept of non-commutative Brillouin torus, and a list of known formulas for various physical response functions is presented. In the second part, auxiliary algebras are introduced and a canonical finite-volume approximation of the non-commutative Brillouin torus is developed. Explicit numerical algorithms for computing generic correlation functions are discussed. In the third part upper bounds on the numerical errors are derived and it is proved that the canonical-finite volume approximation converges extremely fast to the thermodynamic limit. Convergence tests and various applications concludes the presentation.The book is intended for graduate students and researchers in numerical and mathematical physics.

The Glorious Geology of Iceland's Golden Circle (GeoGuide)

by Agust Gudmundsson

This is the first book describing the glorious geology of Iceland’s Golden Circle and four additional excursions:(1) the beautiful valleys and mountains of the fjord of Hvalfjördur, (2) the unique landscape and geothermal fields of the Hengill Volcano, (3) the explosion craters, volcanic fissures, and lava fields of the Reykjanes Peninsula, and (4) the volcanoes (Hekla, Eyjafjallajökull, Katla), waterfalls, sandur plains, and rock columns of South Iceland. The Golden Circle offers a unique opportunity to observe and understand many of our planet’s forces in action. These forces move the Earth’s tectonic plates, rupture the crust, and generate earthquakes, volcanic eruptions, channels for rivers and waterfalls, and heat sources for hot springs and geysers. The Golden Circle includes the famous rifting and earthquake fracture sites at Thingvellir, the hot springs of the Geysir area, the waterfall of Gullfoss, and the Kerid volcanic crater. As the book is primarily intended for people with no background in geosciences, no geological knowledge is assumed and technical terms are avoided as far as possible (those used are explained in a glossary). With more than 240 illustrations – mostly photographs – explaining geological structures and processes, it is also a useful resource for geoscientists.

Connected Lands: New Perspectives on Ecological Networks Planning (UNIPA Springer Series)

by Filippo Schilleci Vincenzo Todaro Francesca Lotta

This book explores and outlines the reference theoretical basis of ecological networks within the international debate, focusing on how protected areas should no longer be considered as the sum of different components but rather as a network. The various European, transnational and national models of ecological networks/connections are analyzed on the basis of a detailed, updated study of relevant documents. The complex picture that emerges shows a wide range of reticular-ecological models within European plans and programs, but also many non-integrated experiences. The book subsequently examines the regulation of ecological networks/connections within planning instruments, explaining the critical points and referring to different ecological network models and specific local realities. Lastly, the book addresses two Italian case studies regarding the different normative and planning frameworks, both at a national and regional level, and demonstrating not only how ecological networks/connections can be structured within plans, but also how these networks/connections represent the core element of territory development and preservation. As such, it provides an essential tool for containing habitat fragmentation, offering a new perspective that integrates theoretical approaches and methods with planning models and the lessons learned from local applications.

Supersymmetric Grand Unified Theories: From Quarks to Strings via SUSY GUTs (Lecture Notes in Physics #939)

by Stuart Raby

These course-tested lectures provide a technical introduction to Supersymmetric Grand Unified Theories (SUSY GUTs), as well as a personal view on the topic by one of the pioneers in the field. While the Standard Model of Particle Physics is incredibly successful in describing the known universe it is, nevertheless, an incomplete theory with many free parameters and open issues. An elegant solution to all of these quandaries is the proposed theory of SUSY GUTs. In a GUT, quarks and leptons are related in a simple way by the unifying symmetry and their electric charges are quantized, further the relative strength of the strong, weak and electromagnetic forces are predicted. SUSY GUTs additionally provide a framework for understanding particle masses and offer candidates for dark matter. Finally, with the extension of SUSY GUTs to string theory, a quantum-mechanically consistent unification of the four known forces (including gravity) is obtained. The book is organized in three sections: the first section contains a brief introduction to the Standard Model, supersymmetry and the Minimal Supersymmetric Standard Model. Then SUSY GUTs in four space-time dimensions are introduced and reviewed. In addition, the cosmological issues concerning SUSY GUTs are discussed. Then the requirements for embedding a 4D SUSY GUT into higher-dimensional theories including gravity (i.e. String Theory) are investigated. Accordingly, section two of the course is devoted to discussing the so-called Orbifold GUTs and how in turn they solve some of the technical problems of 4D SUSY GUTs. Orbifold GUTs introduce a new set of open issues, which are then resolved in the third section in which it is shown how to embed Orbifold GUTs into the E(8) x E(8) Heterotic String in 10 space-time dimensions.

Stability and Suppression of Turbulence in Relaxing Molecular Gas Flows (Fluid Mechanics and Its Applications #117)

by Yurii N. Grigoryev Igor V. Ershov

This book presents an in-depth systematic investigation of a dissipative effect which manifests itself as the growth of hydrodynamic stability and suppression of turbulence in relaxing molecular gas flows. The work describes the theoretical foundations of a new way to control stability and laminar turbulent transitions in aerodynamic flows. It develops hydrodynamic models for describing thermal nonequilibrium gas flows which allow the consideration of suppression of inviscid acoustic waves in 2D shear flows. Then, nonlinear evolution of large-scale vortices and Kelvin-Helmholtz waves in relaxing shear flows are studied. Critical Reynolds numbers in supersonic Couette flows are calculated analytically and numerically within the framework of both linear and nonlinear classical energy hydrodynamic stability theories. The calculations clearly show that the relaxation process can appreciably delay the laminar-turbulent transition. The aim of the book is to show the new dissipative effect, which can be used for flow control and laminarization. This volume will be of interest and useful to mechanical engineers, physicists, and mathematicians who specialize in hydrodynamic stability theory, turbulence, and laminarization of flows.
