This book was released on 1998-01-31 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last 50 years, the perception oftransposable elements (TEs) has changed considerably from selfish DNA to sequences that may contribute significantly to genome function and evolution. The recent increased interest in TEs is based on the realization that they are a major genetic component (at least 10--20%) of all organisms and a major contributor to the mutation process. It is currently estimated that 70--80% of spontaneous mutations are the result of TE-mediated insertions, deletions, or chromosomal rearrangements. Thus, it seems at least plausible that TEs may playa significant role in the adaptation and evolution of natural populations and species. The ubiquity of TEs suggests that they are an old component of genomes which have been vertically transmitted through generations over evolutionary time. However, detailed analyses carried out over the last 20 years have revealed several unusual features of TE evolution: (i) TEs can be horizontally transferred between species; (ii) TE evolutionary rates can be dramatically increased by specific inactivation processes, such as the RIP (Repeat Induced Point mutation) mechanism in fungi; (iii) TEs can influence the regulation of other TEs by insertion or deletion; (iv) different classes of TEs in even distantly related species can be remarkably similar in both structure and function.
Download or read book Chemical Evolution written by Bernd Markert and published by Springer. This book was released on 2015-02-19 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for researchers and students interested in the function and role of chemical elements in biological or environmental systems. Experts have long known that the Periodic System of Elements (PSE) provides only an inadequate chemical description of elements of biological, environmental or medicinal importance. This book explores the notion of a Biological System of the Elements (BSE) established on accurate and precise multi-element data, including evolutionary aspects, representative sampling procedures, inter-element relationships, the physiological function of elements and uptake mechanisms. The book further explores the concept Stoichiometric Network Analysis (SNA) to analyze the biological roles of chemical species. Also discussed is the idea of ecotoxicological identity cards which give a first-hand description of properties relevant for biological and toxicological features of a certain chemical element and its geo biochemically plausible speciation form. The focus of this book goes beyond both classical bioinorganic chemistry and toxicology.

Available in PDF, EPUB and Kindle. Book excerpt: The present work has three principal objectives: (1) to fix the chronology of the development of the pre-Euclidean theory of incommensurable magnitudes beginning from the first discoveries by fifth-century Pythago reans, advancing through the achievements of Theodorus of Cyrene, Theaetetus, Archytas and Eudoxus, and culminating in the formal theory of Elements X; (2) to correlate the stages of this developing theory with the evolution of the Elements as a whole; and (3) to establish that the high standards of rigor characteristic of this evolution were intrinsic to the mathematicians' work. In this third point, we wish to counterbalance a prevalent thesis that the impulse toward mathematical rigor was purely a response to the dialecticians' critique of foundations; on the contrary, we shall see that not until Eudoxus does there appear work which may be described as purely foundational in its intent. Through the examination of these problems, the present work will either alter or set in a new light virtually every standard thesis about the fourth-century Greek geometry. I. THE PRE-EUCLIDEAN THEORY OF INCOMMENSURABLE MAGNITUDES The Euclidean theory of incommensurable magnitudes, as preserved in Book X of the Elements, is a synthetic masterwork. Yet there are detect able seams in its structure, seams revealed both through terminology and through the historical clues provided by the neo-Platonist commentator Proclus.
Download or read book Elements Evolution written by Eric Meyers and published by Astrology Sight. This book was released on 2010 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elements & Evolution: The Spiritual Landscape of Astrology. This groundbreaking, innovative book explores how the 4 elements structure and catalyze spiritual evolution from a number of angles. It explores Cyclical Evolution (the great cycle through the zodiac), and Progressive Evolution (the development of consciousness), and offers commentary on the evolutionary purpose of every facet of astrology. This is not a book about chart interpretation, rather, it aims to reveal the underlying workings of astrology itself. The thought-provoking information may inform anyone s approach to charts by adding layers of nuance, clarifying how the various aspects relate to soul growth, and understanding the relationship of astrology and consciousness. It is already being considered a major contribution by many leaders in the field. Contributions include a new classification of the elements: Water & Fire are discussed as being charged, and Earth & Air are neutral. Progressive evolution discusses how our soul growth occurs at 4 Elemental Levels the physical (Earth), emotional (Water), mental (Air), and soul (Fire). In great detail, this book clarifies the process of spiritual awakening as seen through astrology and the 4 Elements which compose its spiritual landscape.

Download or read book Fingerprint No 2 written by Design Associates Chen and published by Simon and Schuster. This book was released on 2014-07-01 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many designers, creating things by hand is a reaction to too much computer-based design. Since the first Fingerprint was published, ideas that were once on the fringe have begun to thrive in the mainstream. From typography and illustration to book-making and film titles, elements of handcraft have soaked into everyday life. Fingerprint No. 2 reflects the evolution of those ideas. In this second volume, you’ll still find plenty of projects created entirely without the aid of computer technology. But you’ll also discover how designers are beginning to incorporate the two aesthetics—handmade and digital—in order to best communicate their message. A third, hybrid aesthetic is emerging, one that marries the technologies of the past and future into a vibrant, exciting present. Look inside to discover 133 projects and exclusive visual essays from leading designers, including Robynne Raye, Stefan Bucher and Christian Helms. These pieces of work prove that handmade elements are not only vital to excellent design, but often result in exceptional design. Listen for the pulse, which cannot be faked, forged, or falsified. Look for the finger print. It is the key to design’s success.
Download or read book Understanding the Enrichment of Heavy Elements by the Chemodynamical Evolution Models of Dwarf Galaxies written by Yutaka Hirai and published by Springer. This book was released on 2019-04-30 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the mechanism of enrichment of heavy elements in galaxies, a long standing problem in astronomy. It mainly focuses on explaining the origin of heavy elements by performing state-of-the-art, high-resolution hydrodynamic simulations of dwarf galaxies. In this book, the author successfully develops a model of galactic chemodynamical evolution by means of which the neutron star mergers can be used to explain the observed abundance pattern of the heavy elements synthesized by the rapid neutron capture process, such as europium, gold, and uranium in the Local Group dwarf galaxies. The book argues that heavy elements are significant indicators of the evolutionary history of the early galaxies, and presents theoretical findings that open new avenues to understanding the formation and evolution of galaxies based on the abundance of heavy elements in metal-poor stars.
Download or read book Transposable Elements and Genome Evolution written by J. F. McDonald and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once considered merely `selfish' or `parasitic' DNA, transposable elements are today recognized as being of major biological significance. Not only are these elements a major source of mutation, they have contributed both directly and indirectly to the evolution of genome structure and function. On October 8-10, 1999, 100 molecular biologists and evolutionists representing 11 countries met on the campus of The University of Georgia in Athens for the inaugural Georgia Genetics Symposium. The topics of presentations ranged from how the elements themselves have evolved to the impact transposable elements have had on the evolution of their host genomes. The papers in this volume therefore represent state-of-the-art thinking, by leading world experts in the field, on the evolutionary significance of transposable elements.

Download or read book The Gene s Eye View of Evolution written by J. Arvid Ågren and published by Oxford University Press. This book was released on 2021-07-21 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: "To many evolutionary biologists, the central challenge of their discipline is to explain adaptation, the appearance of design in the living world. With the theory of evolution by natural selection, Charles Darwin elegantly showed how a purely mechanistic process can achieve this striking feature of nature. Since then, the way many biologists have thought about evolution and natural selection is as a theory about individual organisms. Over a century later, a subtle but radical shift in perspective emerged with the gene's-eye view of evolution in which natural selection was conceptualized as a struggle between genes for replication and transmission to the next generation. This viewpoint culminated with the publication of The Selfish Gene by Richard Dawkins (Oxford University Press, 1976) and is now commonly referred to as selfish gene thinking. The gene's-eye view has subsequently played a central role in evolutionary biology, although it continues to attract controversy. The central aim of this accessible book is to show how the gene's-eye view differs from the traditional organismal account of evolution, trace its historical origins, clarify typical misunderstandings and, by using examples from contemporary experimental work, show why so many evolutionary biologists still consider it an indispensable heuristic. The book concludes by discussing how selfish gene thinking fits into ongoing debates in evolutionary biology, and what they tell us about the future of the gene's-eye view of evolution."--

Download or read book Protein Metal Interactions written by Mendel Friedman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal ions and proteins are ubiquitous. Therefore, not surprisingly, new protein-metal interactions continue to be dis covered, and their importance is increasingly recognized in both physical and life sciences. Because the subject matter is so broad and affects so many disciplines, in organizing this Symposium, I sought participation of speakers with the broadest possible range of interests. Twenty-two accepted my invitation. To supplement the verbal presentations, the Proceedings include five closely re lated invited contributions. The ideas expressed are those of the various authors and are not necessarily approved or rejected by any agency of the United States Government. No official recommendation concerning the sub ject matter or products discussed is implied in this book. This book encompasses many aspects of this multifaceted field. Topics covered represent biochemical, immunochemical, bioorganic, biophysical, metabolic, nutritional, medical, physiological, toxi cological, environmental, textile, and analytical interests. The discoveries and developments in any of these areas inevitably illumine others. I feel that a main objective of this Symposium, bringing together scientists with widely varied experiences yet with common interests in protein-metal interactions, so that new understanding and new ideas would result has been realized. I hope that the reader enjoys and benefits from reading about the fascinat ing interactions of metal ions and proteins as much as I did.
