“I have endeavoured to give a presentation which is readable by the beginner in the field and also will be useful to those who do or want to do research work in this field. In order to assist the former, I have frequently made use of small type for those sections that are not necessary for an understanding of the fundamentals. For the benefit of those working in the field, numerous references to original papers have been included. “A satisfactory presentation of molecular spectra and molecular structure is nowadays not possible without treating thoroughly, apart from the empirical results, the theoretical background also. Therefore, I have included as much of the theory of molecular spectra as is possible without going into the more difficult mathematical details. A large number of diagrams, graphical representations of eigenfunctions and potential curves, as well as energy level diagrams, serve to illustrate and to explain the theory. On the other hand, I have added numerous carefully selected spectrograms of bands and band systems (some of which have been taken specially for this purpose) in order to give an accurate idea of the experimental material that forms the basis of the developments.
This is a collectively written, inter-disciplinary, thematic cross-national study which combines conceptual, theoretical, empirical and policy material in an ambitious and innovative way to explore a key concept in contemporary European political, policy and academic debates. The first part of the book clarifies the various ways that the concept of citizenship has developed historically and is understood today in a range of Western European welfare states. It elaborates on the contemporary framing of debates and struggles around citizenship. This provides a framework for three policy studies, looking at: migration and multiculturalism; the care of young children; and home-based childcare and transnational dynamics. The book is unusual in weaving together the topics of migration and childcare and in studying these issues together within a gendered citizenship framework. It also demonstrates the value of a multi-level conceptualisation of citizenship, stretching from the domestic sphere through the national and European levels to the global. The book is aimed at students of social policy, sociology, European studies, women's studies and politics and at researchers/scholars/policy analysts in the areas of citizenship, gender, welfare states and migration.
Biomagnetism involves the investigation of bioelectric processes as reflected by their accompanying magnetic fields. These processes can be monitored in the brain, heart, peripheral nerve or gastrointestinal tract. SQUID technology can also be used for biosusceptometry in lung, liver and intestines. Biomagnetism also includes theoretical issues as encountered in the inverse problem, modelling, fundamentals, physics and mathematics of the method, technical applications and instrumentation, as well as future aspects.
Here, the authors provide a unified concept for understanding multi-electron processes in electrochemical systems such as molten salts, ionic liquids, or ionic solutions. A major advantage of this concept is its independence of assumptions like one-step many-electron transfers or ‘discrete’ discharge of complex species. Therefore this monograph is a unique resource for basic electrochemical research but also for many important applications such as electrodeposition, electrorefining, or electrowinning of polyvalent metals from molten salts and other ionic media.
As was announced two years ago, the description of the physical properties of molybde num has now been completed in the present volume up to page 124. Whereas most properties, e.g., the electrical, magnetic, and optical properties, are dealt with in the usual manner, the results of studies of the atom and ion emission had to be presented in a revised form, comprising not only the most recent data but having in mind also the corresponding data for tungsten, which will be represented in a supplement volume now in preparation. The various modes of electron emission have also been studied in great detail. Many more pages (exactly 226 pages, as contrasted to three pages in the Main Volume) were needed to present the electrochemical data for molybdenum, which were published to an astonishingly great extent by Russian workers. The large volume of literature is due to the extensive industrial application of the metaL, cf. "MoLybdän" Erg.-Bd. A 1, 1977, and to its occurrence in various oxidation states. Thus the equilibrium between an Mo eLectrode and Mo ions or between an inert eLectrode and Mo ions is deaLt with in the chapters "Standard PotentiaLs" and "PotentiaLs", whereas kinetics and reaction mechanisms of the reduction and oxidation of Mo ions on a dropping mercury electrode and other inert eLectrodes can be found in the chapter "Polarography/ Voltammetry.
This book provides a comprehensive analysis of social policy in the German Democratic Republic (GDR, 1949-1990), followed by an analysis of the “Social Union”, the transformation of social policy in the process of German unification in 1990. Schmidt’s analysis of the GDR also depicts commonalities and differences between the welfare state in East and West Germany as well as in other East European and Western countries. He concludes that the GDR was unable to cope with the trade-off between ambitious social policy goals and a deteriorating economic performance. Ritter embeds his analysis of the Social Union in a general study of German unification, its international circumstances and its domestic repercussions (1989-1994). He argues that social policy played a pivotal role in German unification, and that there was no alternative to extending the West German welfare state to the East. Ritter, a distinguished historian, bases his contribution on an award-winning study for which he drew on archival sources and interviews with key actors. Schmidt is a distinguished political scientist.
In this extended essay, experts address both the recovery and the long-term goal of healing from addiction, arguing that a full cure from drug addiction or habitual addiction can be achieved. Combining both the principles of systemic therapy and experience gained through years of counseling, they have developed a unique model called “in-depth systemic” therapy, which extends the classic model by introducing and expanding on the mental dimension. The central point of this work is the thesis that addicts themselves have to reorganize and restructure their own habitual ways of perception and cognition, with Vipassana meditation serving as the instrument to realize this transformation. Vipassana comprises an ethical lifestyle, concentration of the mind through meditation, and working progressively on one’s one mental-somatic models, offering a unique and successful approach to the treatment of addiction.
From 1907 to 1931 at Tendaguru, a remote site in present-day Tanzania, teams of German (and later British) paleontologists unearthed 220 tons of fossils, including the bones of a new dinosaur, one of the largest then known. For decades the mounted skeleton of this giant, Brachiosaurus, was the largest skeleton of a land animal on exhibit in the world. The dinosaur and other animal fossils found at Tendaguru form one of the cornerstones of our understanding of life in the Mesozoic era. Visited sporadically during the '30s and '40s, Tendaguru again became the site of scientific interest late in the 20th century. African Dinosaurs Unearthed tells the story of driven scientific adventurers working under difficult conditions and often paying the price with their health—and sometimes with their lives. Set against the background of a troubled century, the book reveals how scientific endeavors were carried on through war and political turmoil, and continue into the present day.
The International Lateinamerika-Kolloquium, held in April 2009 at the Geosciences Centre of the Georg-August-Universitt̃ Gt̲tingen, brings together researchers from all fields of earth sciences. The abstracts contained in this volume cover a wide range of topics on the geological evolution of the South American continent and its margins, such as processes of mountain building, uplift and erosion as well as interaction between tectonic and climatic parameters. Topics of the Lateinamerika-Kolloquium also cover landscape evolution, ecology, natural resources, geo-hazards and economic geology.
Philosophy of Science: A Unified Approach combines a general introduction to philosophy of science with an integrated survey of all its important subfields. As the book’s subtitle suggests, this excellent overview is guided methodologically by "a unified approach" to philosophy of science: behind the diversity of scientific fields one can recognize a methodological unity of the sciences. This unity is worked out in this book, revealing all the while important differences between subject areas. Structurally, this comprehensive book offers a two-part approach, which makes it an excellent introduction for students new to the field and a useful resource for more advanced students. Each chapter is divided into two sections. The first section assumes no foreknowledge of the subject introduced, and the second section builds upon the first by bringing into the conversation more advanced, complementary topics. Definitions, key propositions, examples and figures overview all of the core material. At the end of every chapter there are selected readings and exercises (with solutions at the end of the book). The book also includes a comprehensive bibliography and an index.
More than 80 personalities, in or from Germany, that over the centuries have shaped the development of analytical chemistry are introduced by brief biographies. These accounts go beyond summarising key biographical information and outline the individual's contributions to analytical chemistry. This richly illustrated Brief offers a unique resource of information that is not available elsewhere.
This illustrated handbook describes a broad spectrum of methods in the fields of remote sensing, geophysics, geology, hydrogeology, geochemistry, and microbiology designed to investigate landfill, mining and industrial sites. The descriptions provide information about the principle of the methods, applications and fundamentals. This handbook also deals with the stepwise procedure for investigating sites and common problems faced in efficient implementation of field operations.
This book introduces the techniques of Instrumental Analysis with respect to fundamental basics, technical realization, key applications, major strengths and limitations. The approach used is to highlight differences and consolidate similarities of the techniques, focusing especially on the viewpoint of the laboratory rather than on the scientific ideal or the limits of what is possible.
Most of the cranial sense organs of vertebrates arise from embryonic structures known as cranial placodes. Such placodes also give rise to sensory neurons that transmit information to the brain as well as to many neurosecretory cells. This book focuses on the development of sensory and neurosecretory cell types from cranial placodes by introducing the vertebrate head with its sense organs and neurosecretory organs and providing an overview of the various cranial placodes and their derivatives, including evidence of common embryonic primordia. Schlosser discusses how these primordia are established in the early embryo and how individual placodes develop. The latter chapters explain how various placodally derived sensory and neurosecretory cell types differentiate into discrete structures.
The subject of this book is the solution of stiff differential equations and of differential-algebraic systems. This second edition contains new material including new numerical tests, recent progress in numerical differential-algebraic equations, and improved FORTRAN codes. From the reviews: "A superb book...Throughout, illuminating graphics, sketches and quotes from papers of researchers in the field add an element of easy informality and motivate the text." --MATHEMATICS TODAY
In this book the authors examine the relations between work and time and explore the possibilities of developing new and more flexible working patterns.
The leading idea of epistemology in the Enlightenment tradition was foundation-theoretic: to reach knowledge, we must not legitimize our beliefs by external authorities, but instead justify them by rational arguments. Recently, the foundation-theoretic ideal of justification has come under attack, the chief criticism being that universal standards of justification are illusory because the problem of a regress of justification is unsolvable. Alternatives to foundation theory (coherentism, externalism, or dogmatism) have been developed that give up central claims of Enlightenment epistemology such as empirical support, cognitive accessibility, or rational justifiability. Optimality Justifications develops a new account of foundation-theoretic epistemology based on the method of optimality justifications. Optimality justifications offer a solution to the regress problem. Rather than striving for a priori demonstrations of reliability, which are impossible, they show that certain epistemic methods are optimal with regard to all accessible alternatives, which is more modestly but provably possible. In particular, optimality justifications can achieve a non-circular justification of deductive, inductive, and abductive reasoning. This volume pursues two goals: a general renewal of foundation-theoretic epistemology based on the account of optimality justifications, and the advancement of methods of optimality justification in important domains of epistemology and the philosophy of science, logic, and cognition. Connected with these goals is the aspiration to develop new ideas for mainstream epistemology, as well as for formal epistemology, philosophy of science, and cognitive science, which are intended to attract researchers, students, and all other readers interested in these fields.
Title first published in 2003. This informative volume addresses the impact of the EU on national policies to combat poverty in European member states. The editors bring together leading academics to discuss the issue of and fight against poverty in Germany in particular, within the context of ongoing trends and debates across other European states.
The annual meeting of the Astronomische Gesellschaft in Cologne, June 1988, featured extensive reviews of the chemical processes relevant to astrophysics. The twelve contributions to this book, written by experts from the US, UK, France, Belgium, Switzerland and Germany, deal in depth with the chemistry of comets and meteorites, of stars and their shells, of the interstellar medium and galaxies. A comprehensive review of nucleosynthesis and two reports on observations round off an up-to-date presentation of cosmic chemistry.
The book is aimed at applied statisticians, graduate students of statistics, and students and researchers with a strong interest in statistics and data analysis. This second edition is extensively revised, especially those sections relating with Bayesian concepts.
The International Scientific Spring Meeting of the Astronomische Ge sellschaft (AG) held at Bamberg in April 1991 was devoted to "Vari abilities in Stars and Galaxies". Time-dependent phenomena are observed in a wide range of as tronomical objects. They are caused by different physical mechanisms (for example by pulsation, by accretion, or by dramatic eruptive events in connection with mass outflow) producing observable intensity vari ations through all wavelengths. Many of the papers in this volume are concerned with galactic stars showing such behaviour (for ex ample cataclysmic variables, symbiotic stars, luminous blue variables (LBVs) and novae). Intrinsic variations of the, magnetic field struc ture on observable time scales are, for instance, a peculiarity of cool, solar-like stars and represent a useful tool to study differential rotation and cycles of activity. Recent results on the investigation of gas motions in the inner regions of the Milky Way system, a study of the bipolar galaxy M 82, observations of variable extragalactic radio sources, the variability of emission lines in active galactic nuclei (AGN) as well as continuum variations of quasars and AGN are discussed by several authors. The yearbook series Reviews in Modern Astronomy of the AG to bring the scientific events of the was established in 1988 in order meetings of the society to the attention of the worldwide astronomical community.
Since Jean Bodin and Thomas Hobbes, political theorists have depicted the state as "sovereign" because it holds preeminent authority over all the denizens belonging to its geographically defined territory. From the Peace of Westphalia in 1648 until the beginning of World War I in 1914, the essential responsiblities ascribed to the sovereign state were maintaining internal and external security and promoting domestic prosperity. This idea of "the state" in political theory is clearly inadequate to the realities of national governments and international relations at the beginning of the twenty-first century. During the twentieth century, the sovereign state, as a reality and an idea, has been variously challenged from without and within its borders. Where will the state head in the age of globalisation? Can Catholic political thinking contribute to an adequate concept of statehood and government? A group of German and American scholars were asked to explore specific ways in which the intellectual traditions of Catholicism might help our effort lo rethink the state. The debate is guided by the conviction that these intellectual resources will prove valuable to political theorists as they work to revise our understanding of the state.
Starting with the simplest semiclassical approaches and ending with the description of complex fully quantum-mechanical methods for quantum transport analysis of state-of-the-art devices, Computational Electronics: Semiclassical and Quantum Device Modeling and Simulation provides a comprehensive overview of the essential techniques and methods for effectively analyzing transport in semiconductor devices. With the transistor reaching its limits and new device designs and paradigms of operation being explored, this timely resource delivers the simulation methods needed to properly model state-of-the-art nanoscale devices. The first part examines semiclassical transport methods, including drift-diffusion, hydrodynamic, and Monte Carlo methods for solving the Boltzmann transport equation. Details regarding numerical implementation and sample codes are provided as templates for sophisticated simulation software. The second part introduces the density gradient method, quantum hydrodynamics, and the concept of effective potentials used to account for quantum-mechanical space quantization effects in particle-based simulators. Highlighting the need for quantum transport approaches, it describes various quantum effects that appear in current and future devices being mass-produced or fabricated as a proof of concept. In this context, it introduces the concept of effective potential used to approximately include quantum-mechanical space-quantization effects within the semiclassical particle-based device simulation scheme. Addressing the practical aspects of computational electronics, this authoritative resource concludes by addressing some of the open questions related to quantum transport not covered in most books. Complete with self-study problems and numerous examples throughout, this book supplies readers with the practical understanding required to create their own simulators.
This book introduces basic and advanced concepts of categorical regression with a focus on the structuring constituents of regression, including regularization techniques to structure predictors. In addition to standard methods such as the logit and probit model and extensions to multivariate settings, the author presents more recent developments in flexible and high-dimensional regression, which allow weakening of assumptions on the structuring of the predictor and yield fits that are closer to the data. A generalized linear model is used as a unifying framework whenever possible in particular parametric models that are treated within this framework. Many topics not normally included in books on categorical data analysis are treated here, such as nonparametric regression; selection of predictors by regularized estimation procedures; ternative models like the hurdle model and zero-inflated regression models for count data; and non-standard tree-based ensemble methods. The book is accompanied by an R package that contains data sets and code for all the examples.
The book describes the physical properties of gases and describes the different measuring methods and sensor principles for the analysis of gas mixtures. The use of gas sensors in different applications is shown by means of practical examples. These applications of the metrological detection of gases originate from many fields of engineering, in particular energy technology, food technology, process engineering, biotechnology, safety engineering, medical technology and environmental technology. This book is a translation of the original German 1st edition Gasmesstechnik in Theorie und Praxis by Gerhard Wiegleb, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2017. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
Hitler’s path to war consisted of two different stages that paralleled the internal development of Germany. From 1933 to the end of 1936, he created a diplomatic revolution in Europe. From a barely accepted equal, Germany became the dominant power on the continent. With the remilitarization of the Rhineland, the stalemate in the Spanish Civil War, the forming of the Axis, and the signing of the Anti-Comintern Pact, the first phase was completed. In the second phase, the diplomatic initiative in the world belonged to Germany and its partners. Germany’s march toward war therefore became the central issue in world diplomacy.
This publication is based on the plant processes and reaction sites for which reliable knowledge on both their physiology and biochem-istry and the mode of herbicidal action is available. Targets of the agrochemical research, such as enzymes of biosynthetic pathways or herbicide-binding peptides in the photosynthetic membrane, are highlighted. Detailed knowledge about the target sites will allow bio-chemical model systems to evaluate the biological activity of newly synthesized compounds before their conventional screening in the greenhouse. Quantitative structure/activity relationships should be performed more reliably with simple biological species or enzymol-ogy assays, to aid in the rational design of pesticides. This text is highly valuable for plant physiologists, pathologists, and chemists in the agrochemical industry and universities.
Closing the gap between electrochemical engineering science and electrochemical technology, this volume is for all electrochemists and electrochemical engineers, metallurgists, engineers in chemical process, galvanic, metallurgical and electric power industries.
Most vertebrate cranial sense organs arise from placodes. These placodes give rise to sensory neurons that transmit information to the brain and neurosecretory cells. This book reviews the evolutionary origin of the sensory and neurosecretory cell types. It summarizes our current understanding of vertebrate evolution, clarifies conceptual issues relating to homology and evolutionary innovation of cell types, compares the sensory and neurosecretory cell types with similar cell types in other animals, and addresses the question of how cranial placodes evolved as novel structures in vertebrates by redeploying pre-existing and sometimes evolutionarily ancient cell types.
