This volume comprises the proceedings of a NATO Advanced Study Institute held in Geilo, Norway, between 8-19 April 1985. Although the principal support for the meeting was provided by the NATO Committee for Scientific Affairs, a number of additional sponsors also contributed, allowing the assembly of an unusually large number of internationally rec ognized speakers. Additional funds were received from: EXXON Research and Engineering Co. IBM (Europe) Institutt for energiteknikk (NorwaY) Institut Lauge-Langevin (France) The Norwegian Research Council for Science and Humanities NORDITA (Denmark) The Norwegian Foreign Office The U. S. Army Research, Development and Standardization Group (Europe) The U. S. National Science Foundation - The Norwegian Council for Science and Letters The organizing committee would like to take this opportunity to thank these contributors for their help in promoting a most exciting rewarding meeting. This Study Institute was the eighth of a series of meetings held in Geilo on subjects related to phase transitions. In contrast to previous meetings which were principally concerned with transitions in ordered systems, this school addressed the problems which arise when structural order is absent. The unifying feature among the subjects discussed at the school and the link to themes of earlier meetings was the concept of scaling.
Australia’s venomous snakes are widely viewed as the world’s most deadly and are regarded with cautious curiosity, fascination and, regrettably, fear. Australia’s Dangerous Snakes examines the biology, natural history, venom properties and bite treatment of medically important venomous marine and terrestrial snakes. It contains comprehensive identification profiles for each species, supported by keys and photographs. In addition to their medical importance, the environmental roles of these snakes and the threats that are causing the decline of many of these reptiles are discussed. Drawing on the authors’ experience in the fields of herpetology, toxinology and clinical medicine, this book stimulates respect and admiration and dispels fear of Australia’s fascinating snakes. Australia’s Dangerous Snakes will provide hours of rewarding reading and valuable information for anyone interested in Australia’s unique wildlife and natural history, and will be an essential reference for herpetologists, toxinologists, physicians, zoo personnel and private snake collectors.
CONTINUOUS COVER FORESTRY Gain expertise in the development of healthier, more sustainable forests with this indispensable guide Continuous Cover Forestry (CCF) is an approach to forest management with over a century of history, one which applies ecological principles to the project of developing biologically diverse, structurally complex forests. Long used as the standard forest management method in Central Europe, CCF is generating renewed interest globally for its potential to develop and sustain forests that can withstand climate change impacts, maintain forest biodiversity in the face of major ecological challenges and offer better recreation experience. There is an increasingly urgent need for forest scientists and policymakers to be familiar with the toolkit provided by CCF. Continuous Cover Forestry: Theories, Concepts, and Implementation provides a thorough, up-to-date introduction to the theory and practice of CCF. Beginning with an overview of the method’s history and its foundational principles, the book provides detailed guidance for applying CCF methods to a range of ecological scenarios and forest types. The result is a clear, comprehensive portrait of this increasingly effective set of forestry tools. Continuous Cover Forestry readers will also find: Case studies throughout showing CCF at work in real-world forests Detailed discussion of topics such as forest structure, transformation, silvicultural systems, training, carbon forestry, conservation and more R code ready to take and apply Simple, adaptable models for deriving quantitative guidelines for CCF woodlands Continuous Cover Forestry is ideal for students, scholars and practitioners of forest science, forest ecology, conservation, and environmental management, as well as policymakers dealing with forestry or climate policy.

This textbook provides a comprehensive and instructive coverage of vehicular traffic flow dynamics and modeling. It makes this fascinating interdisciplinary topic, which to date was only documented in parts by specialized monographs, accessible to a broad readership. Numerous figures and problems with solutions help the reader to quickly understand and practice the presented concepts. This book is targeted at students of physics and traffic engineering and, more generally, also at students and professionals in computer science, mathematics, and interdisciplinary topics. It also offers material for project work in programming and simulation at college and university level. The main part, after presenting different categories of traffic data, is devoted to a mathematical description of the dynamics of traffic flow, covering macroscopic models which describe traffic in terms of density, as well as microscopic many-particle models in which each particle corresponds to a vehicle and its driver. Focus chapters on traffic instabilities and model calibration/validation present these topics in a novel and systematic way. Finally, the theoretical framework is shown at work in selected applications such as traffic-state and travel-time estimation, intelligent transportation systems, traffic operations management, and a detailed physics-based model for fuel consumption and emissions.
This book provides a systematic description of the molecular structures and bonding in simple compounds of the main group elements with particular emphasis on bond distances, bond energies and coordination geometries. The description includes the structures of hydrogen, halogen and methyl derivatives of the elements in each group, some of these molecules are ionic, some polar covalent. The survey of molecules whose structures conform to well-established trends is followed byrepresentative examples of molecules that do not conform. We also describe electron donor-acceptor and hydrogen bonded complexes.Chemists use models to systematize our knowledge, to memorize information and to predict the structures of compounds that have not yet been studied. The book provides a lucid discussion of a number of models such as the Lewis electron-pair bond and the VSEPR models, the spherical and polarizable ion models, and molecular orbital calculations, and it outlines the successes and failures of each.
Arne Naess is considered one of the most important philosophers of the twentieth century. He has been a tremendously prolific author, yet his works as a whole have remained largely unavailable – until now. Springer made available for the first time, a definitive 10-volume collection of Arne Naess’s life’s works: The Selected Works of Arne Naess. The Selected Works of Arne Naess (SWAN) presents a major overview of Arne Naess’s thinking and provides an extensive collection of this prolific philosopher’s principal writings. Some of Naess’s most important publications have never before been available in English. Many others are out of print. Often, his papers were published in obscure and inaccessible journals. And because Naess has been so prolific, many of his most important papers still remain unpublished. The publication of SWAN makes Naess’s work more fully accessible to scholars, students, and critics alike.
This work is motivated by and develops connections between several branches of mathematics and physics--the theories of Lie algebras, finite groups and modular functions in mathematics, and string theory in physics. The first part of the book presents a new mathematical theory of vertex operator algebras, the algebraic counterpart of two-dimensional holomorphic conformal quantum field theory. The remaining part constructs the Monster finite simple group as the automorphism group of a very special vertex operator algebra, called the "moonshine module" because of its relevance to "monstrous moonshine.
The self-contained treatment covers Fourier series, orthogonal systems, Fourier and Laplace transforms, Bessel functions, and partial differential equations of the first and second orders. 266 exercises with solutions. 1970 edition.
Seeds are a vital part of life on earth. They are fundamental for plant reproduction, and many seeds play an important role in the diet of man and domestic and wild animals. Knowledge of the appearance of seeds - seed morphology - is of great importance to botany and seed identification in relation to: seed setting, quarantine work, forensic work, seed poisening, studies of seed dispersal, seed banks and archaeological studies.;This bibliography contains 3775 references and is divided in two parts: handbooks, and articles and monographs. In the latter the bibliographical reference is supplemented by information of importance to seed identificaiton: genera mentioned in articles, keys, descriptions, drawings, photograph, scanning electron micrographs, anatomy and chemical methods. The index of authors contains the names of an extensive number of authors, cited in the bibliography, and in the index of genera more than 3900 genera, described in one or more of the publications are cited.
This is an in-depth study of not just about Tan Kah-kee, but also the making of a legend through his deeds, self-sacrifices, fortitude and foresight. This revised edition sheds new light on his political agonies in Mao's China over campaigns against capitalists and intellectuals.
This textbook effectively builds a bridge from basic number theory to recent advances in applied number theory. It presents the first unified account of the four major areas of application where number theory plays a fundamental role, namely cryptography, coding theory, quasi-Monte Carlo methods, and pseudorandom number generation, allowing the authors to delineate the manifold links and interrelations between these areas. Number theory, which Carl-Friedrich Gauss famously dubbed the queen of mathematics, has always been considered a very beautiful field of mathematics, producing lovely results and elegant proofs. While only very few real-life applications were known in the past, today number theory can be found in everyday life: in supermarket bar code scanners, in our cars’ GPS systems, in online banking, etc. Starting with a brief introductory course on number theory in Chapter 1, which makes the book more accessible for undergraduates, the authors describe the four main application areas in Chapters 2-5 and offer a glimpse of advanced results that are presented without proofs and require more advanced mathematical skills. In the last chapter they review several further applications of number theory, ranging from check-digit systems to quantum computation and the organization of raster-graphics memory. Upper-level undergraduates, graduates and researchers in the field of number theory will find this book to be a valuable resource.
This monograph is concerned with Galois theoretical embedding problems of so-called Brauer type with a focus on 2-groups and on finding explicit criteria for solvability and explicit constructions of the solutions. Before considering questions of reducing the embedding problems and reformulating the solvability criteria, the author provides the necessary theory of Brauer groups, group cohomology and quadratic forms. The book will be suitable for students seeking an introduction to embedding problems and inverse Galois theory. It will also be a useful reference for researchers in the field.
In this volume, the authors show that a set of local admissible fields generates a vertex algebra. For an affine Lie algebra $\tilde{\frak g}$, they construct the corresponding level $k$ vertex operator algebra and show that level $k$ highest weight $\tilde{\frak g}$-modules are modules for this vertex operator algebra. They determine the set of annihilating fields of level $k$ standard modules and study the corresponding loop $\tilde{\frak g}$-module--the set of relations that defines standard modules. In the case when $\tilde{\frak g}$ is of type $A{(1)} 1$, they construct bases of standard modules parameterized by colored partitions, and as a consequence, obtain a series of Rogers-Ramanujan type combinatorial identities.
Coded Modulation Systems is an introduction to the subject of coded modulation in digital communication. It is designed for classroom use and for anyone wanting to learn the ideas behind this modern kind of coding. Coded modulation is signal encoding that takes into account the nature of the channel over which it is used. Traditional error correcting codes work with bits and add redundant bits in order to correct transmission errors. In coded modulation, continuous time signals and their phases and amplitudes play the major role. The coding can be seen as a patterning of these quantities. The object is still to correct errors, but more fundamentally, it is to conserve signal energy and bandwidth at a given error performance. The book divides coded modulation into three major parts. Trellis coded modulation (TCM) schemes encode the points of QAM constellations; lattice coding and set-partition techniques play major roles here. Continuous-phase modulation (CPM) codes encode the signal phase, and create constant envelope RF signals. The partial-response signaling (PRS) field includes intersymbol interference problems, signals generated by real convolution, and signals created by lowpass filtering. In addition to these topics, the book covers coding techniques of several kinds for fading channels, spread spectrum and repeat-request systems. The history of the subject is fully traced back to the formative work of Shannon in 1949. Full explanation of the basics and complete homework problems make the book ideal for self-study or classroom use.
The aim of this book is to introduce the reader to the fascinating world of convex polytopes. The highlights of the book are three main theorems in the combinatorial theory of convex polytopes, known as the Dehn-Sommerville Relations, the Upper Bound Theorem and the Lower Bound Theorem. All the background information on convex sets and convex polytopes which is m~eded to under stand and appreciate these three theorems is developed in detail. This background material also forms a basis for studying other aspects of polytope theory. The Dehn-Sommerville Relations are classical, whereas the proofs of the Upper Bound Theorem and the Lower Bound Theorem are of more recent date: they were found in the early 1970's by P. McMullen and D. Barnette, respectively. A famous conjecture of P. McMullen on the charac terization off-vectors of simplicial or simple polytopes dates from the same period; the book ends with a brief discussion of this conjecture and some of its relations to the Dehn-Sommerville Relations, the Upper Bound Theorem and the Lower Bound Theorem. However, the recent proofs that McMullen's conditions are both sufficient (L. J. Billera and C. W. Lee, 1980) and necessary (R. P. Stanley, 1980) go beyond the scope of the book. Prerequisites for reading the book are modest: standard linear algebra and elementary point set topology in [R1d will suffice.
For more than a century, we have had a firm grasp on rotor dynamics involving rigid bodies with regular shapes, such as cylinders and shafts. However, to achieve an equally solid understanding of the rotational behavior of flexible bodies-especially those with irregular shapes, such as propeller and turbine blades-we require more modern tools and m
Model-driven individual-based forest ecology and individual-based methods in forest management are of increasing importance in many parts of the world. For the first time this book integrates three main fields of forest ecology and management, i.e. tree/plant interactions, biometry of plant growth and human behaviour in forests. Individual-based forest ecology and management is an interdisciplinary research field with a focus on how the individual behaviour of plants contributes to the formation of spatial patterns that evolve through time. Key to this research is a strict bottom-up approach where the shaping and characteristics of plant communities are mostly the result of interactions between plants and between plants and humans. This book unites important methods of individual-based forest ecology and management from point process statistics, individual-based modelling, plant growth science and behavioural statistics. For ease of access, better understanding and transparency the methods are accompanied by R code and worked examples.
This report presents the Round-Robin (RR) program and test results including a statistical evaluation of the RILEM TC195-DTD committee named “Recommendation for test methods for autogenous deformation (AD) and thermal dilation (TD) of early age concrete”. The task of the committee was to investigate the linear test set-up for AD and TD measurements (Dilation Rigs) in the period from setting to the end of the hardening phase some weeks after. These are the stress-inducing deformations in a hardening concrete structure subjected to restraint conditions. The main task was to carry out an RR program on testing of AD of one concrete at 20 °C isothermal conditions in Dilation Rigs. The concrete part materials were distributed to 10 laboratories (Canada, Denmark, France, Germany, Japan, The Netherlands, Norway, Sweden and USA), and in total 30 tests on AD were carried out. Some supporting tests were also performed, as well as a smaller RR on cement paste. The committee has worked out a test procedure recommendation which is reported separately and submitted acceptance as a RILEM method.
This is the first extensive study of a major Patristic work, showing its importance for the history of Church and theology, Manichaean studies and the use of ancient philosophy. It includes a critical text and translation of central passages.
Arne Burkhardt, Walter Lang and Norbert Schwarz give an overview over mechanisms of damage that lead to death and health impairment after corona "vaccinations". The Authors Arne Burkhardt and Walter Lang are pathologists with more than 40 years of professional experience. Together with, Norbert Schwarz, a medical scientist and epidemiologist, they examined more than 85 tissue samples from individuals, who had died after corona "vaccination" and more than 75 biopsy samples from individuals, who suffered serious health impairment. In parallel they reviewed the pertinent literature. This is a translation from German to English by one of the authors (Norbert Schwarz). No proofreading by a native speaker has been done.
Scientific interest in regulatory T cells has revived during the last decade. Initially described in the early seventies as suppressor T cells, the concept of suppressor/regulatory T cells went through turbulent times during the eighties when molecular analysis failed to identify putative suppressor genes. The constructive and elegant cellular experiments on regulatory T cells during the nineties, initiated by Shimon Sakaguchi and co-workers, however have brought these cells back into the limelight. Nowadays, regulatory T cells are regarded as essential components of the immune system, and several different subsets of regulatory T cells have been described. Considerable regulatory function has been attributed to the CD4+CD25+ T cell subset. These cells act by suppressing adaptive and possibly also innate immune responses thereby maintaining or restoring the balance between immunity and tolerance. The suppressive effects of CD4+CD25+ regulatory T cells are cell-contact dependent but a role for soluble factors, particularly in vivo, has been suggested as well. The aim of this book is to bring together recent developments and viewpoints in the field of CD4+CD25+ regulatory T cells and to discuss the potential use of regulatory T cells in immunotherapy of inflammatory diseases. By linking data on regulatory T cells from experimental models with recent findings from the clinic, this topical book will be of interest to immunologists and other biomedical researchers as well as clinicians that are interested in regulation and manipulation of the immune response during (chronic) inflammatory disease.
Nutrition Economics: Principles and Policy Applications establishes the core criteria for consideration as new policies and regulations are developed, including application-based principles that ensure practical, effective implementation of policy. From the economic contribution of nutrition on quality of life, to the costs of malnutrition on society from both an individual and governmental level, this book guides the reader through the factors that can determine the success or failure of a nutrition policy. Written by an expert in policy development, and incorporating an encompassing view of the factors that impact nutrition from an economic standpoint (and their resulting effects), this book is unique in its focus on guiding other professionals and those in advanced stages of study to important considerations for correct policy modeling and evaluation. As creating policy without a comprehensive understanding of the relevant contributing factors that lead to failure is not an option, this book provides a timely reference. - Connects the direct and indirect impacts of economic policy on nutritional status - Provides practical insights into the analysis of nutrition policies and programs that will produce meaningful results - Presents a hands-on approach on how to apply economic theory to the design of nutritional policies and programs
Throughout history, climate change has been an important driving force behind human behaviour. This archaeological study seeks to understand the complex interrelations between that behaviour and climatic fluctuations, focussing on how climate affected the social relations between neighbouring communities of occasionally differing nature. It is argued that developments in these relations will fall within a continuum between competition on one end and cooperation on the other. The adoption of a particular strategy depends on whether that strategy is advantageous to a community in terms of the maintenance of its well-being when faced with adverse climate change. This model will be applied to northern Mesopotamia between 3000 and 1600 BC. Local palaeoclimate proxy records demonstrate that aridity increased significantly during this period. Within this geographical, chronological, and climatic framework, this study looks at changes in settlement patterns as an indication of competition among sedentary agriculturalist communities, and the development of the Amorite ethnic identity as reflecting cooperation among sedentary and more mobile pastoralist communities.
