Download or read book Evolution Seen from the Phase Diagram of Life written by Shigeki Mitaku and published by Springer Nature. This book was released on 2024 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zusammenfassung: This book aims to understand biological evolution through a physical approach, focusing on the macroscopic aspects of the biological genome. Readers will discover the connection between genomic information and the harmony of biological systems, a relationship that remains elusive to many researchers in biological sciences. The most common approach to understanding living organisms with physics is to begin with a single molecule of an organism. In contrast to this bottom-up approach, building from each molecule to the whole, this book takes a coarse-grained approach at the amino acid level to physically understand the macroscopic aspects of the organism. The book presents a system developed by the authors to predict membrane proteins with high accuracy using only physical parameters. Another distinctive perspective of this book is that it proposes the idea of a physical mechanism, other than natural selection, that orchestrates the emergence of order from random processes. The study of macroscopic aspects of living organisms based on this concept has parallels with thermostatistical mechanics for states of matter. Just as random processes create order in matter, there are physical random processes that form order in living organisms. This analogy is the central theme of the book. Using terms and analogies familiar to physicists, the book bridges the gap between biological and physical sciences. The book focuses on simple principles and is aimed primarily at researchers. While the content of this book is at the boundary area of biophysics, soft matter physics and bioinformatics, it will also be of interest to researchers and graduate students working on any biological topics. This book is a translation of an original German edition. 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

Download or read book Phase Diagrams of the Elements written by David A. Young and published by Univ of California Press. This book was released on 2023-12-22 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behavior of solid and liquid matter at high pressures and temperatures is best described in a phase diagram, which shows the regions of stability of different phases of the material. Thanks to the diamond-anvil cell, which has made possible much higher pressures, and to new and very accurate theoretical models and methods, Phase Diagrams of the Elements presents the most up-to-date information on the phase behavior of all the chemical elements from hydrogen to fermium. The book summarizes, with the aid of tables and illustrations, the experimental data and the theoretical calculations. Each element is discussed in a separate section. Other chapters deal with methods, the liquid-vapor transition, and an overview of the elements. While comprehensively reviewing all that has been done in this important area, the author also points to questions that need much more experimental and theoretical work.
Download or read book Phase Evolution of Boron Nitride and Carbide during Chemical Vapor Deposition written by Sachin Sharma and published by Linköping University Electronic Press. This book was released on 2024-05-02 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin films of Boron Nitride (BN) and Boron Carbide (BC) possess properties that make them attractive for various applications. Epitaxially grown BN exhibits potential for optoelectronic devices, as piezoelectric materials, and graphene technology. Epitaxial BC is a semiconductor that could allow bandgap tuning and has potential applications in thermoelectric and optoelectronic devices. Both BN and BC material systems, generally deposited using chemical vapour deposition (CVD), are limited by the lack of control in depositing epitaxial films. In my thesis work, I have studied the evolution of various crystal phases of BN and BC and the factors that affect them during their CVD processes. I deposited and compared the growth of BN on Al2O3 (0001), (11 2 over bar 0), (1 1 over bar 02) and (10 1 over bar 0) substrates and used two organoboranes as boron precursors. Only Al2O3(11 2 over bar 0) and Al2O3 (0001) rendered crystalline films while the BN growth on the remaining substrates was X-ray amorphous. Furthermore, the less investigated Al2O3(11 2 over bar 0) had better crystalline quality versus the commonly used Al2O3 (0001). To further understand this, I studied crystalline BN thin films on an atomic scale and with a time evolution approach, uncovering the influence of carbon on hexagonal BN (h-BN). I showed that h-BN nucleates on both substrates but then either polytype transforms to rhombohedral-BN (r-BN) in stages, turns to less ordered turbostratic-BN or is terminated. An increase in local carbon content is the cause of these changes in epitaxial BN films during CVD. From the time evolution, we studied the effect of Al2O3 modification on h-BN nucleation during CVD. The interaction between boron and carbon during BN growth motivated studies also on the BxC materials. BxC was deposited using CVD at different temperatures on 4H-SiC(0001) (Si-face) and 4H-SiC(000 1 over bar) (C-face) substrates. Epitaxial rhombohedral-B4C (r-B4C) grew at 1300 °C on the C-face while the films deposited on the Si-face were polycrystalline. Comparing the initial nucleation layers on both 4H-SiC substrates on an atomic scale we showed that no interface phenomena are affecting epitaxial r-B4C growth conditions. We suggest that the difference in surface energy on the two substrate surfaces is the most plausible reason for the differences in epitaxial r-B4C growth conditions. In this thesis work, I identify the challenges and propose alternative routes to synthesise epitaxial BN and B4C materials using CVD. This fundamental materials science work enhances the understanding of growing these material systems epitaxially and in doing so furthers their development.
Download or read book A Biologist s Guide to Mathematical Modeling in Ecology and Evolution written by Sarah P. Otto and published by Princeton University Press. This book was released on 2011-09-19 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty years ago, biologists could get by with a rudimentary grasp of mathematics and modeling. Not so today. In seeking to answer fundamental questions about how biological systems function and change over time, the modern biologist is as likely to rely on sophisticated mathematical and computer-based models as traditional fieldwork. In this book, Sarah Otto and Troy Day provide biology students with the tools necessary to both interpret models and to build their own. The book starts at an elementary level of mathematical modeling, assuming that the reader has had high school mathematics and first-year calculus. Otto and Day then gradually build in depth and complexity, from classic models in ecology and evolution to more intricate class-structured and probabilistic models. The authors provide primers with instructive exercises to introduce readers to the more advanced subjects of linear algebra and probability theory. Through examples, they describe how models have been used to understand such topics as the spread of HIV, chaos, the age structure of a country, speciation, and extinction. Ecologists and evolutionary biologists today need enough mathematical training to be able to assess the power and limits of biological models and to develop theories and models themselves. This innovative book will be an indispensable guide to the world of mathematical models for the next generation of biologists. A how-to guide for developing new mathematical models in biology Provides step-by-step recipes for constructing and analyzing models Interesting biological applications Explores classical models in ecology and evolution Questions at the end of every chapter Primers cover important mathematical topics Exercises with answers Appendixes summarize useful rules Labs and advanced material available

Available in PDF, EPUB and Kindle. Book excerpt: As both individuals and societies, we are making decisions today that will have profound consequences for future generations. From preserving Earth's plants and animals to altering our use of fossil fuels, none of these decisions can be made wisely without a thorough understanding of life's history on our planet through biological evolution. Companion to the best selling title Teaching About Evolution and the Nature of Science, Evolution in Hawaii examines evolution and the nature of science by looking at a specific part of the world. Tracing the evolutionary pathways in Hawaii, we are able to draw powerful conclusions about evolution's occurrence, mechanisms, and courses. This practical book has been specifically designed to give teachers and their students an opportunity to gain a deeper understanding of evolution using exercises with real genetic data to explore and investigate speciation and the probable order in which speciation occurred based on the ages of the Hawaiian Islands. By focusing on one set of islands, this book illuminates the general principles of evolutionary biology and demonstrate how ongoing research will continue to expand our knowledge of the natural world.

Many experts in various fields from China and around the world gather together at the conference to review, exchange, summarize and promote their achievements in the fields of industrial engineering and engineering management. For example, some experts pay special attention to the current state of the application of related techniques in China as well as their future prospects, such as green product design, quality control and management, supply chain and logistics management to address the need for, amongst other things low-carbon, energy-saving and emission-reduction. They also offer opinions on the outlook for the development of related techniques. The proceedings offers impressive methods and concrete applications for experts from colleges and universities, research institutions and enterprises who are engaged in theoretical research into industrial engineering and engineering management and its applications. As all the papers are of great value from both an academic and a practical point of view, they also provide research data for international scholars who are investigating Chinese style enterprises and engineering management.
Download or read book Post AGB Objects as a Phase of Stellar Evolution written by R. Szczerba and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term proto-planetary nebulae (PPNe) in the context of the late stages of stellar evolution was created only slightly more than 20 years ago to express the belief that in the near future these objects will become planetary nebulae (PNe). The first proto-planetary nebulae (called also post-Asymptotic Giant Branch, or shortly post-AGB objects) AFGL 2688 and AFGL 618 were discovered in mid seventies in course of the Air Force Sky Survey. Investigation of this phase of stellar evolution developed very rapidly in 1980's after the IRAS mission when it became clear that proto-planetary nebulae emit a significant part of their energy in the mid-and far-infrared. Hundreds of new candidates have been proposed but the recognition of the real proto-planetary nebulae is not a simple task and needs a substantial effort to exclude cases that represent different evolutionary stages. High resolution spectroscopy of stellar atmospheres is of much importance in this respect. Surprisingly, only a small group of central stars, the so called 21 11m emitters, show chemical signatures of the 3 rd dredge up process. Very recently, a more detailed studies of mid-infrared spectra from the Infrared Space Observatory (ISO) allow for a better understanding of chemical composition and evolution of circumstellar material around these stars. A new impetus in the field of proto-planetary nebulae research was started in the 1990's with high spatial resolution imaging in mid-infrared and optical wavelength ranges.

Download or read book Phase Diagrams 6 II written by Allen Alper and published by Elsevier. This book was released on 2012-12-02 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase Diagrams: Materials Science and Technology, Volume II covers the use of phase diagrams in metals, refractories, ceramics, and cements. Divided into 10 chapters, this volume first describes the main features of phase diagrams representing systems in which the oxygen pressure is an important parameter, starting with binary systems and proceeding toward the more complicated ternary and quaternary systems. The subsequent chapters discuss the application of phase diagrams in several refractory systems. A chapter covers the procedures used for cement production and some of the available phase-equilibrium data and their application to specific situations. This volume also deals with the application of phase diagrams to extraction metallurgy, with an emphasis on oxide systems, as well as in ceramic and metal sintering. The concluding chapters explore the relationship of heat treatment of metals and alloys to their phase diagrams. These chapters also deal with the use of phase diagrams in several techniques of joining metals, such as fusion welding, brazing, solid-state bonding, and soldering. This volume will be useful to all scientists, engineers, and materials science students who are investigating and developing materials, as well as to the end users of the materials.
Download or read book The Ecology and Evolution of Inducible Defenses written by Ralph Tollrian and published by Princeton University Press. This book was released on 2021-04-13 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inducible defenses--those often dramatic phenotypic shifts in prey activated by biological agents ranging from predators to pathogens--are widespread in the natural world. Yet research on the inducible defenses used by vertebrates, invertebrates, and plants in terrestrial, marine, and freshwater habitats has largely developed along independent lines. Ralph Tollrian and Drew Harvell seek to change that here. By bringing together leading researchers from all fields to review common themes and explore emerging ideas, this book represents the most current and comprehensive survey of knowledge about the ecology and evolution of inducible defenses. Contributors examine organisms as different as unicellular algae and higher vertebrates, and consider defenses ranging from immune systems to protective changes in morphology, behavior, chemistry, and life history. The authors of the review chapters, case studies, and theoretical studies pinpoint unifying factors favoring the evolution of inducible defenses. Throughout, the volume emphasizes a multidisciplinary approach, integrating applied and theoretical ecology, evolution, genetics, and chemistry. In addition, Harvell and Tollrian provide an introduction and a conclusion that review the current state of knowledge in the field and identify areas for future research. The contributors, in addition to the editors, are May Berenbaum, Arthur Zangerl, Johannes Järemo, Juha Tuomi, Patric Nilsson, Anurag Agrawal, Richard Karban, Marcel Dicke, Ellen Van Donk, Miquel Lürling, Winfried Lampert, Simon Frost, John Gilbert, Hans-Werner Kuhlmann, Jürgen Kusch, Klaus Heckmann, Luc De Meester, Piotr Dawidowicz, Erik van Gool, Carsten Loose, Stanley Dodson, Christer Brönmark, Lars Pettersson, Anders Nilsson, Bradley Anholt, Earl Werner, Curtis Lively, Frederick Adler, Daniel Grünbaum, and Wilfried Gabriel.
Download or read book Evolution Time Production and the Environment written by Malte Faber and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition is brought about by two factors. First, the initial printing sold out much more rapidly than we expected. Second, several colleagues have been kind enough to suggest that this book not only has a contribution to make to ecological economics, but also has relevance to economics general. Thus our OUf distinction distinction between between genotypic genotypic and phenotypic evolution may be used to characterise not only economic sectors, but also whole economies, and in particular economic schools of thought. For instance, the Austrian subjectivist school deals explicitly with ignorance and the emergence of novelty, and may therefore be used to analyse genotypic development. In contrast, neoclassical economics deals principally with phenotypic development. When Dr. Müller Muller of Springer-Verlag suggested the production of a second edition, we were therefore pleased that this book might remain available. Several readers and in particular reviewers of the first edition remarked, in one way or the other, that they had questions concerning several of our OUf concepts, concepts, such as genotype, phenotype, ignorance, surprise, sUlprise, novelty, novelty, knowledge, knowledge, predictable predictable and unpredictable processes etc. Of course, all these concepts are of importance for evolution in general and for invention and innovation of new techniques in particular. We therefore considered some modifications and extensions of the original text, but on the advice of colleagues, have restricted oUfselves ourselves to correcting mistakes that crept into the first edition and to two extensions ofthe of the text, text, one major, one smaller.
