Natural Hybridization and Evolution (Oxford Series in Ecology and Evolution)

by Michael L. Arnold

This study draws on data from numerous sources that support the paradigm of natural hybridization as an important evolutionary process. The review of these data results in a challenge to the framework used by many evolutionary biologists, which sees the process of natural hybridization as maladaptive because it represents a violation of divergent evolution. In contrast, this book presents evidence of a significant role for natural hybridization in furthering adaptive evolution and evolutionary diversification in both plants and animals.

Evolutionary Quantitative Genetics

by Prof Stevan J. Arnold

Evolutionary quantitative genetics (EQG) provides a formal theoretical foundation for quantitatively linking natural selection and genetic variation to the rate and expanse of adaptive evolution. It has become the dominant conceptual framework for interpreting the evolution of quantitative traits in terms of elementary forces (mutation, inheritance, selection, and drift). Despite this success, the relevance of EQG to many biological scenarios remains relatively unappreciated, with numerous fields yet to fully embrace its approach. Part of the reason for this lag is that conceptual advances in EQG have not yet been fully synthesized and made accessible to a wider academic audience. A comprehensive, accessible overview is therefore now timely, and Evolutionary Quantitative Genetics provides this much-needed synthesis. The central argument of the book is that an adaptive landscape concept can be used to understand both evolutionary process within lineages and the pattern of adaptive radiations. In particular, it provides a convincing argument that models with a moving adaptive peak carry us further than any other conceptual approach yet devised. Although additive theory holds center stage, the book mentions and references departures from additivity including non-Gaussian distributions of allelic effects, dominance, epistasis, maternal effects and phenotypic plasticity. This accessible, advanced textbook is aimed principally at students (from senior undergraduate to postgraduate) as well as practising scientists in the fields of evolutionary biology, ecology, physiology, functional morphology, developmental biology, comparative biology, paleontology, and beyond who are interested in how adaptive radiations are produced by evolutionary and ecological processes.

Getting Started in Radio Astronomy: Beginner Projects for the Amateur (The Patrick Moore Practical Astronomy Series)

by Steven Arnold

Radio astronomy is a mystery to the majority of amateur astronomers, yet it is the best subject to turn to when desirous of an expanded knowledge of the sky. This guide intends to instruct complete newcomers to radio astronomy, and provides help for the first steps on the road towards the study of this fascinating subject. In addition to a history of the science behind the pursuit, directions are included for four easy-to-build projects, based around long-term NASA and Stanford Solar Center projects. The first three projects constitute self-contained units available as kits, so there is no need to hunt around for parts. The fourth – more advanced – project encourages readers to do their own research and track down items. Getting Started in Radio Astronomy provides an overall introduction to listening in on the radio spectrum. With details of equipment that really works, a list of suppliers, lists of online help forums, and written by someone who has actually built and operated the tools described, this book contains everything the newcomer to radio astronomy needs to get going.

Dynamical Systems V: Bifurcation Theory and Catastrophe Theory

by V.I. Arnold V.S. Afrajmovich Yu.S. Il'yashenko L.P. Shil'nikov

Bifurcation theory and catastrophe theory are two well-known areas within the field of dynamical systems. Both are studies of smooth systems, focusing on properties that seem to be manifestly non-smooth. Bifurcation theory is concerned with the sudden changes that occur in a system when one or more parameters are varied. Examples of such are familiar to students of differential equations, from phase portraits. Understanding the bifurcations of the differential equations that describe real physical systems provides important information about the behavior of the systems. Catastrophe theory became quite famous during the 1970's, mostly because of the sensation caused by the usually less than rigorous applications of its principal ideas to "hot topics", such as the characterization of personalities and the difference between a "genius" and a "maniac". Catastrophe theory is accurately described as singularity theory and its (genuine) applications. The authors of this book, previously published as Volume 5 of the Encyclopaedia, have given a masterly exposition of these two theories, with penetrating insight.

Gewöhnliche Differentialgleichungen (Springer-Lehrbuch)

by Vladimir I. Arnold

nen (die fast unverändert in moderne Lehrbücher der Analysis übernommen wurde) ermöglichten ihm nach seinen eigenen Worten, "in einer halben Vier­ telstunde" die Flächen beliebiger Figuren zu vergleichen. Newton zeigte, daß die Koeffizienten seiner Reihen proportional zu den sukzessiven Ableitungen der Funktion sind, doch ging er darauf nicht weiter ein, da er zu Recht meinte, daß die Rechnungen in der Analysis bequemer auszuführen sind, wenn man nicht mit höheren Ableitungen arbeitet, sondern die ersten Glieder der Reihenentwicklung ausrechnet. Für Newton diente der Zusammenhang zwischen den Koeffizienten der Reihe und den Ableitungen eher dazu, die Ableitungen zu berechnen als die Reihe aufzustellen. Eine von Newtons wichtigsten Leistungen war seine Theorie des Sonnensy­ stems, die in den "Mathematischen Prinzipien der Naturlehre" ("Principia") ohne Verwendung der mathematischen Analysis dargestellt ist. Allgemein wird angenommen, daß Newton das allgemeine Gravitationsgesetz mit Hilfe seiner Analysis entdeckt habe. Tatsächlich hat Newton (1680) lediglich be­ wiesen, daß die Bahnkurven in einem Anziehungsfeld Ellipsen sind, wenn die Anziehungskraft invers proportional zum Abstandsquadrat ist: Auf das Ge­ setz selbst wurde Newton von Hooke (1635-1703) hingewiesen (vgl. § 8) und es scheint, daß es noch von weiteren Forschern vermutet wurde.

Mathematical Events of the Twentieth Century

by Vladimir I. Arnold Ludwig Faddeev Yu. I. Manin V. B. Filippov Vladimir M. Tikhomirov Anatoly M. Vershik

This book contains several contributions on the most outstanding events in the development of twentieth century mathematics, representing a wide variety of specialities in which Russian and Soviet mathematicians played a considerable role. The articles are written in an informal style, from mathematical philosophy to the description of the development of ideas, personal memories and give a unique account of personal meetings with famous representatives of twentieth century mathematics who exerted great influence in its development. This book will be of great interest to mathematicians, who will enjoy seeing their own specialities described with some historical perspective. Historians will read it with the same motive, and perhaps also to select topics for future investigation.

Non-destructive Materials Characterization and Evaluation (Springer Series in Materials Science #329)

by Walter Arnold Klaus Goebbels Anish Kumar

This book is devoted to non-destructive materials characterization (NDMC) using different non-destructive evaluation techniques. It presents theoretical basis, physical understanding, and technological developments in the field of NDMC with suitable examples for engineering and materials science applications. It is written for engineers and researchers in R&D, design, production, quality assurance, and non-destructive testing and evaluation. The relevance of NDMC is to achieve higher reliability, safety, and productivity for monitoring production processes and also for in-service inspections for detection of degradations, which are often precursors of macro-defects and failure of components. Ultrasonic, magnetic, electromagnetic and X-rays based NDMC techniques are discussed in detail with brief discussions on electron and positron based techniques.

Partnership and Leadership: Building Alliances for a Sustainable Future (Eco-Efficiency in Industry and Science #8)

by ArnoldTukker Theo J. N. M.Bruijn

Sustainable development has become a central perspective in environmental strategies around the world. It is clear that neither governments nor businesses have the capability to bring about sustainability on their own. Therefore, collaboration has emerged as a central concept. At the same time it is obvious that someone has to take the lead in the development towards sustainability. This book focuses on different forms of collaboration emerging between various actors. The objective of the book is to more systematically explore the different roles and relationships between partnership and leadership. Basically, both partnership and leadership can be seen in a positive and negative way: for example, as far as partnership is concerned, we can assume that the path towards sustainability can be paved by parties coming together, taking some initiative collaborating. On the opposite, partnership and consensus-based decisions can be seen as an obstacle to foster radical changes in production and consumption patterns. Similarly, leadership can be seen as an obstacle to sustainable development if leaders form close circles and are not willing to share experiences with other actors; but leadership could also be considered as an important element to keep concepts and practices forward. The book holds this double perspective: explaining, mapping and analyzing different goals/formats/methods of more and less collaborative approaches, but at the same time taking a critical approach to the theme by understanding related risks, effects, prospects and corrective actions. Next to a conceptual part, the book brings together case-studies from around the world. The focus is in describing and understanding various formats of collaboration and critically evaluating its effects and prospects. A concluding chapter discusses the role of partnership and leadership in realizing various levels of environmental innovations: optimization and re-design, that usually affect only a small part of the production/consumption structure, and much more complicated, radical innovations that have to deal with societal (sub)systems. The book is in part an edited version of selected papers presented during the 1998 Greening of Industry Conference in Rome on the subject, enriched with contributions of other invited authors.

Pflanzenernährung (Handbuch der Pflanzenernährung und Düngung #1 / 1)

by D. I. Arnon W. Baumeister W. U. Behrens E. v. Boguslawski M. J. Bukovac H. Burghardt M. Erichsen W. Flaig W. H. Fuchs F. Grossmann F. Heilinger G. P. Hill J. Jung H. Kick J. G. Kisser P. J. Kramer H. Kühn P. Limberg H. Linser H. H. Mayr K. Mengel K.-H. Neumann K. Scharrer G. Schmid W. Schuster H. B. Tukey H. Walter S. H. Wittwer

Seit dem Erscheinen des zweibändigen Standardwerkes von F. HoNCAMP, "Handbuch der Pflanzenernährung und Düngerlehre", sind mehr als dreißig Jahre vergangen. Bei den stürmischen Fortschritten auf allen Gebieten der Natur­ wissenschaften, insbesondere der Chemie, Pflanzenphysiologie, Biochemie, Bodenkunde und Technologie, ist dieses zur Zeit seines Erscheinens so aus­ gezeichnete Handbuch natürlich längst veraltet. Zweifellos besteht heute ein dringendes Bedürfnis nach einem ähnlichen Werk. Wenn wir von dem ursprünglichen Plan abgekommen sind, das HoNCAMP­ sche Handbuch in neuer Auflage zu bearbeiten, so vor allem deswegen, weil die tiefgreifende Entwicklung auf diesem Gebiet eine völlig neue Gestaltung des Werkes geboten erscheinen ließ. Es gliedert sich nun in drei Bände. Band I behandelt im wesentlichen die physiologischen Grundlagen der Pflanzenernährung. Er enthält eine ausführliche und systematische Darstellung der eigentlichen Ernährungsphysiologie. Auf eine Erörterung der allgemeinen pflanzenphysiologischen Grundlagen konnte dabei verzichtet werden, weil im RuHLANDschEin "Handbuch der Pflanzenphysiologie" ein umfassendes und modernes Nachschlagewerk zur Verfügung steht. Band II beschäftigt sich mit dem Boden und den Düngemitteln. Unter Berücksichtigung der modernen Agrikulturchemie haben wir das heutige Wissen über den Boden als Standort und Nährstoffquelle der Pflanze unter den Verhält­ nissen der landwirtschaftlichen Praxis und des Gartenbaues bzw. des Forstwesens systematisch zusammengefaßt. Die folgenden Kapitel befassen sich mit der Beschreibung und Herstellung der verschiedenen Wirtschafts- und Handels­ düngemittel. Gerade auf diesem Gebiet bestehen in der wissenschaftlichen Literatur erhebliche Lücken, da keine größeren Lehr- oder Handbücher vorhanden sind, die sich eingehender mit der Technologie der Düngemittel und der Düngung beschäftigen.

Agricultural Research and Technology Transfer

by Isaac Arnon

Agricultural research was probably the first and is the most widespread form of organised research in the world, and one in which both the most developed and underdeveloped countries are engaged. Whilst most forms of research activity, such as in the field of medicine, have world­ wide application, agricultural research, by its very nature, has to be regional; practically no research finding can be adopted without studying the results of its application under the infinite number of ecological situations with which the farmers of the world are faced. The improvement of agricultural production is the essential first step whereby developing countries can hope to raise their standard of living. Research is therefore an activity in which no underdeveloped country can afford not to engage; nor can countries in which agriculture has reached a high level of development and sophistication afford to neglect agricultural research. It is not because of inertia or vested interests that highly industrialised countries maintain, mostly at public expense, a costly and complex infrastructure for agricultural research. Even when problems of overproduction weigh heavily on the economy, agricultural research is considered the essential key to further progress: the objectives and goals are simply changed and adapted to the needs of the economy.

Translational Neuroimmunology in Multiple Sclerosis: From Disease Mechanisms to Clinical Applications

by Ruth Arnon Ariel Miller

Multiple sclerosis (MS) is the most common disabling neurological disease of young adults. More than 2.3 million people are affected by MS worldwide. Symptoms can vary widely, depending on the localization and amount of the damage induced by combined inflammatory, demyelinating, and neurodegenerative processes. Although a cure for MS does not currently exist, therapies can help treat MS attacks, attenuate disease activity, reduce progress of the disease, and manage symptoms. Translational Neuroimmunology in Multiple Sclerosis provides an overview of recent findings and knowledge of the neuroimmunology of multiple sclerosis, from experimental models and the human disease to the translation of this research to immunotherapeutic strategies. Chapters describe genetic and environmental factors underlying the disease pathogenesis of MS as a basis for development of immunotherapies, immunological markers of disease activity, pharmacogenetics, and responses to therapy. Immunomodulatory therapies currently in practice and future therapeutic strategies on the horizon—such as neuroprotective strategies, stem cells, and repair promotion—are discussed. Contributed by renowned leaders in the field, this cross-disciplinary volume is a great resource for basic scientists and clinical practitioners in neuroscience, neurology, immunology, pharmacology, and in-drug development.Provides an overview of recent findings and knowledge of the neuroimmunology of multiple sclerosis and the translation of this research to immunotherapy treatmentEdited by renowned leaders in the field of neuroimmunology and multiple sclerosisContains the latest resource material for basic and clinical scientists and practitioners in neuroscience, neurology, immunology, and pharmacology2017 BMA Medical Book Awards Highly Commended in Neurology
