Geoheritage of the Middle Atlas (Geoheritage, Geoparks and Geotourism)

by Khaoula Baadi

This book is a condensed summary of a broad spectrum of the geological heritage of the Middle Atlas. It has the particularity of proposing an in-depth synthesis and a critical review of the geoheritage of the region. The book addresses the issues related to geoheritage and methodologies for the selection, inventory, assessment and preservation of geosites. It reviews the state of the art of geoheritage in Morocco, particularly in the Middle Atlas, in order to identify geosites with rare and unique geological features. The book presents a detailed study of lithostratigraphic and sedimentological heritage as geosites witnessing at different spatial and temporal scales the evolution and the stratigraphic, sedimentological and paleogeographic history of the Middle Atlas range. It also presents the paleontological heritage of vertebrates by reviewing the discoveries of paleontological sites and their risks in order to present its conservation plans. It also addresses the hydric and fluvial heritage by presenting the potential of water resources and the impact of climate change on the latter. Furthermore, it highlights the karst heritage by exposing an inventory of exo- and endokarst geosites in order to emphasize some unique sites on a national and African scale as well as revealing the underground biodiversity related to this heritage. Finally, it proposes a presentation of the volcanic heritage in order to assess the volcanic geosites that testify to the strombolian, phreatomagmatic and Hawaiian dynamism of the region. The book is mainly intended for researchers, geologists and specialists of the Moroccan Middle Atlas region wishing to acquire a broad multidisciplinary or even transdisciplinary knowledge. It will also be accessible to a non-initiated public, interested in the richness of the Moroccan geoheritage, as well as to Moroccan territorial authorities (High Commission for Water and Forests, Ministry of Tourism, National Institute of Archaeology and Heritage Sciences, etc.) who can benefit from it in the perspective of their strategies of preservation of the national geological heritage. This work will be an example for geoscientists, on an African scale, of a valorization of territorial geological heritage.

Mikromagnetische Charakterisierung des Ermüdungsverhaltens und der Eigenspannungsrelaxation tiefgebohrter Proben des Vergütungsstahls 42CrMo4 (Werkstofftechnische Berichte │ Reports of Materials Science and Engineering)

by Nikolas Baak

Nikolas Baak befasst sich mit der Qualifizierung mikromagnetischer Methoden zur Bewertung der durch Tiefbohren erzeugten Randzonen hinsichtlich ihrer Oberflächenintegrität und deren Einfluss auf das Ermüdungsverhalten. Dabei wird das Ziel verfolgt, durch den Bohrprozess einen vorteilhaften Eigenspannungszustand zu erreichen. Beim hier eingesetzten Einlippen-Tiefbohren kommt es aufgrund des asymmetrischen Werkzeugaufbaus zu einer Art Festwalzprozess. Dadurch werden sowohl sehr hohe Oberflächengüten, als auch der gewünschte Druckeigenspannungszustand erzeugt. Da die meisten Verfahren zur Bestimmung der Oberflächenintegrität entweder zerstörend sind oder auch einen freien Zugang zur Oberfläche benötigen, werden hier zerstörungsfreie Prüfverfahren dafür ertüchtigt, die Oberflächenintegrität sowie den Ermüdungszustand der Bauteile zu bestimmen. Für beide hier betrachteten mikromagnetischen Verfahren, einerseits die Barkhausenrauschen-Analyse und andererseits die Wirbelstromprüfung, werden speziell angefertigte Sensoren, welche das Messsignal an der Innenseite der Bohrung detektieren können, verwendet. Die Messdaten der mikromagnetischen Verfahren werden mit den etablierten Verfahren zur Bestimmung der Oberflächenintegrität, wie bspw. Röntgendiffraktometrie, korreliert.

The Theoretical Foundations of Quantum Mechanics

by Belal E. Baaquie

The Theoretical Foundations of Quantum Mechanics addresses fundamental issues that are not discussed in most books on quantum mechanics. This book focuses on analyzing the underlying principles of quantum mechanics and explaining the conceptual and theoretical underpinning of quantum mechanics. In particular, the concepts of quantum indeterminacy, quantum measurement and quantum superposition are analyzed to clarify the concepts that are implicit in the formulation of quantum mechanics.The Schrodinger equation is never solved in the book. Rather, the discussion on the fundamentals of quantum mechanics is treated in a rigorous manner based on the mathematics of quantum mechanics. The new concept of the interplay of empirical and trans-empirical constructs in quantum mechanics is introduced to clarify the foundations of quantum mechanics and to explain the counter-intuitive construction of nature in quantum mechanics.The Theoretical Foundations of Quantum Mechanics is aimed at the advanced undergraduate and assumes introductory knowledge of quantum mechanics. Its objective is to provide a solid foundation for the reader to reach a deeper understanding of the principles of quantum mechanics.

Brain Function and Oscillations: Volume II: Integrative Brain Function. Neurophysiology and Cognitive Processes (Springer Series in Synergetics)

by Erol Başar

Neuroscience is ripe for a paradigm change as Freeman and Mountcastle describe. Brain Oscillations provide an important key to this change. In this book the functional importance of the brain's multiple oscillations is treated with an integrative scope. According to the author, neurophysiology and cognition demand integrative approaches similar to those of Galilei and Newton in physics and of Darwin in biology. Not only the human brain but also lower brains and ganglia of invertebrates are treated with electrophysical methods. Experiments on sensory registration, perception, movement, and cognitive processes related to attention, learning, and memory are described. A synopsis on brain functions leads to a new neuron assemblies doctrine, extending the concept of Sherrington, and new trends in this field. The book will appeal to scientists and graduate students.

Brain Function and Oscillations: Volume I: Brain Oscillations. Principles and Approaches (Springer Series in Synergetics)

by Erol Başar

by W. J. Freeman These two volumes on "Brain Oscillations" appear at a most opportune time. As the "Decade of the Brain" draws to its close, brain science is coming to terms with its ultimate problem: understanding the mechanisms by which the immense number of neurons in the human brain interact to produce the higher cognitive functions. The ideas, concepts, methods, interpretations and examples, which are presented here in voluminous detail by a world-class authority in electrophysiology, summarize the intellectual equipment that will be required to construct satisfactory solutions to the problem. Neuroscience is ripe for change. The last revolution of ideas took place in the middle of the century now ending, when the field took a sharp turn into a novel direction. During the preceding five decades the prevailing view, carried forward from the 19th century, was that neurons are the carriers of nerve energy, either in chemical or electrical forms (Freeman, 1995). That point of view was enormously productive in terms of coming to understand the chemical basis for synaptic transmission, the electrochemistry of the ac­ tion potential, the ionic mechanisms of membrane currents and gates, the functional neuroanatomy that underlies the hierarchy of reflexes, and the neural fields and'their resonances that support Gestalt phenomena. No bet­ ter testimony can be given of the power of the applications of this approach than to point out that it provides the scientific basis for contemporary neu­ rology, neuropsychiatry, and brain imaging.

Ethics in Biodiversity Conservation (Routledge Studies in Conservation and the Environment)

by Patrik Baard

This book examines the role of ethics and philosophy in biodiversity conservation. The objective of this book is two-fold: on the one hand it offers a detailed and systematic account of central normative concepts often used, but rarely explicated nor justified, within conservation biology. Such concepts include ‘values’ (both intrinsic, instrumental, and, more recently, relational), ‘rights’, and ‘duties’. The second objective is to emphasize to environmental philosophers and applied ethicists the many interesting decision-making challenges of biodiversity conservation. The book argues that a nuanced account of instrumental values provides a powerful tool for reasoning about the values of biodiversity. It also scrutinizes relational values, the concept of rights of nature, and risk, and show how moral philosophy proves indispensable for these concepts. Consequently, it engages with recent suggestions on normative aspects of biodiversity conservation, and show the need for moral philosophy in biodiversity conservation. The overriding aim of this book is to provide conservation biologists and policy-makers with a systematic overview of concepts and assessments of the reasons for reaching prescriptive conclusions about biodiversity conservation. This will prove instrumental in clarifying the role of applied ethics and a refined understanding of the tools it can provide. This title will be of interest to students and scholars of conservation biology, conservation policy, environmental ethics and environmental philosophy.

Eco-facts and Eco-fiction: Understanding the Environmental Debate

by William H. Baarschers

Ozone-friendly, recyclable, zero-waste, elimination of toxic chemicals - such environmental ideals are believed to offer solutions to the environmental crisis. Where do these ideals come from? Is the environmental debate communicating the right problems? Eco-Facts and Eco-Fiction examines serious errors in perceptions about human and environmental health. Drawing on a wealth of everyday examples of local and global concerns, the author explains basic concepts and observations relating to the environment. Removing fear of science and technology and eliminating wrong perceptions lead to a more informed understanding of the environment as a science, a philosophy, and a lifestyle. By revealing the flaws in today's environmental vocabulary, this book stresses the urgent need for a common language in the environmental debate. Such a common language encourages the effective communication between environmental science and environmental decision-making that is essential for finding solutions to environmental problems.

Algebraic Topology: The Abel Symposium 2007 (Abel Symposia #4)

by Nils Baas Eric Friedlander Bjö Jahren Paul Arne Østvær

The 2007 Abel Symposium took place at the University of Oslo in August 2007. The goal of the symposium was to bring together mathematicians whose research efforts have led to recent advances in algebraic geometry, algebraic K-theory, algebraic topology, and mathematical physics. A common theme of this symposium was the development of new perspectives and new constructions with a categorical flavor. As the lectures at the symposium and the papers of this volume demonstrate, these perspectives and constructions have enabled a broadening of vistas, a synergy between once-differentiated subjects, and solutions to mathematical problems both old and new.

by Alper Baba Jochen Bundschuh D. Chandrasekharam

In the region comprising Turkey and Greece, people have been using water from geothermal sources for bathing and washing of clothes since ancient times. This region falls within the Alpine-Himalayan orogenic belt and hence is a locus of active volcanism and tectonism and experiences frequent seismic events. This volcanic and tectonic activity has g

Groundwater and Ecosystems (Nato Science Series: IV: #70)

by Alper Baba Ken W. F. Howard Orhan Gunduz

Many problems related to groundwater and ecosystems are shared by countries throughout the world and there is growing recognition that much can be gained by co-operation on an international scale. This is no time for complacency and it is critical that key problems be identified, that the potential consequences of these problems be understood, and that the development of solutions begins urgently. Important data gaps must be recognized and filled without delay.

Waves and Tidal Flat Ecosystems

by Eiichi Baba Hideo Kawarada Wataru Nishijima Mitsumasa Okada Hiroshi Suito

The authors explain the rewarding results from the interdisciplinary collaboration between an environmental study group working on coastal ecosystems and effects of oil spills and applied mathematicians modelling wave motion on sandy beaches. By using the unified Navier-Stokes equations with a Bingham fluid model for spilled oil, multi-phase flow analysis were made. Decomposition of spilled oil by bacteria was simulated as a chemical reaction, and the theoretical and numerical analysis suggested a countermeasure to help reduce stress on coastal ecosystems. The new understanding of how ecosystems both depend upon, and help to determine, the nature of the shoreline demonstrates promising ways to better assist and exploit the regenerative powers inherent in nature.

Water Security in Asia: Opportunities and Challenges in the Context of Climate Change (Springer Water)

by Mukand Babel Andreas Haarstrick Lars Ribbe Victor R. Shinde Norbert Dichtl

This book assesses the current water-security situation in Asia. The thematic areas of the book discuss the United Nation’s sustainable development goals with a particular focus on Goal 6 (“Ensure availability and sustainable management of water and sanitation”) and Goal 13 (“Take urgent action to combat climate change and its impacts”). Asia has been facing a number of water-related challenges for decades due to multiple factors such as increasing population, socio-economic development, urbanization and migration, and climate change now poses an additional threat. While significant efforts have been made by governments in Asia, much more work is needed to make Asian societies water-secure. Given its multi-disciplinary approach, the book is a valuable resource for researchers involved in the further development of water-security concepts, approaches, and methodologies. In addition, it helps policymakers, planners, and practitioners to formulate sustainable water- security enhancement strategies grounded in sound scientific evidence to protect human well-being.

Band-Ferromagnetism: Ground-State and Finite-Temperature Phenomena (Lecture Notes in Physics #580)

by K. Baberschke M. Donath W. Nolting

The fascinating phenomenon ferromagnetism is far from being fully understood, although it surely belongs to the oldest problems of solid state physics. For any investigation it appears recommendable to distinguish between materials whose spontaneous magnetization stems from localized electrons of a partially ?lled atomic shell and those in which it is due to itinerant electrons of a partially ?lled conduction band. In the latter case one speaks of band-ferromagnetism, prototypes of which are the classical ferromagnets Fe, Co, and Ni. The present book is a status report on the remarkable progress that has recently been made towards a microscopic understanding of band-ferromagnetism as an electron c- relation e?ect. The authors of the various chapters of this book “Band-Ferromagnetism: Ground-State and Finite-Temperature Phenomena” participated as selected - perts in the 242nd WE-Heraeus-Seminar (4-6 October 2000) held under almost the same title in Wandlitz near Berlin (Germany). It was the second seminar of this type in Wandlitz. (The ?rst in 1998 dealt with the complementary topic of the physics of local-moment ferromagnets such as Gd). Twenty-six invited spe- ers from ten di?erent countries together with ?fty-?ve further participants, who presented contributions in form of posters, spent three days together discussing in an enthusiastic and fertile manner the hot topics of band-ferromagnetism.

Partial Differential Equations V: Asymptotic Methods for Partial Differential Equations (Encyclopaedia of Mathematical Sciences #34)

by V. M. Babich N. S. Bakhvalov M. V. Fedoryuk A. M. Il'In V. F. Lazutkin G. Panasenko A. L. Shtaras B. R. Vainberg

In this paper we shall discuss the construction of formal short-wave asymp­ totic solutions of problems of mathematical physics. The topic is very broad. It can somewhat conveniently be divided into three parts: 1. Finding the short-wave asymptotics of a rather narrow class of problems, which admit a solution in an explicit form, via formulas that represent this solution. 2. Finding formal asymptotic solutions of equations that describe wave processes by basing them on some ansatz or other. We explain what 2 means. Giving an ansatz is knowing how to give a formula for the desired asymptotic solution in the form of a series or some expression containing a series, where the analytic nature of the terms of these series is indicated up to functions and coefficients that are undetermined at the first stage of consideration. The second stage is to determine these functions and coefficients using a direct substitution of the ansatz in the equation, the boundary conditions and the initial conditions. Sometimes it is necessary to use different ansiitze in different domains, and in the overlapping parts of these domains the formal asymptotic solutions must be asymptotically equivalent (the method of matched asymptotic expansions). The basis for success in the search for formal asymptotic solutions is a suitable choice of ansiitze. The study of the asymptotics of explicit solutions of special model problems allows us to "surmise" what the correct ansiitze are for the general solution.

Neoclassical Theory of Electromagnetic Interactions: A Single Theory for Macroscopic and Microscopic Scales (Theoretical and Mathematical Physics)

by Anatoli Babin Alexander Figotin

In this monograph, the authors present their recently developed theory of electromagnetic interactions. This neoclassical approach extends the classical electromagnetic theory down to atomic scales and allows the explanation of various non-classical phenomena in the same framework.While the classical Maxwell–Lorentz electromagnetism theory succeeds in describing the physical reality at macroscopic scales, it struggles at atomic scales. Here, quantum mechanics traditionally takes over to describe non-classical phenomena such as the hydrogen spectrum and de Broglie waves. By means of modifying the classical theory, the approach presented here is able to consistently explain quantum-mechanical effects, and while similar to quantum mechanics in some respects, this neoclassical theory also differs markedly from it. In particular, the newly developed framework omits probabilistic interpretations of the wave function and features a new fundamental spatial scale which, at the size of the free electron, is much larger than the classical electron radius and is relevant to plasmonics and emission physics.This book will appeal to researchers interested in advanced aspects of electromagnetic theory. Treating the classical approach in detail, including non-relativistic aspects and the Lagrangian framework, and comparing the neoclassical theory with quantum mechanics and the de Broglie–Bohm theory, this work is completely self-contained.
