Describing how to investigate all kinds of galaxies through a multifrequency analysis, this text is divided into three different sections. The first describes the data currently available at different frequencies, from X-rays to UV, optical, infrared and radio millimetric and centimetric, while explaining their physical meaning. In the second section, the author explains how these data can be used to determine physical parameters and quantities, such as mass and temperature. The final section is devoted to describing how the derived quantities can be used in a multifrequency analysis to study such physical processes as the star formation cycle and constrain models of galaxy evolution. As a result, observers will be able to interpret galaxies and their structure.

Distance determination is an essential technique in astronomy, and is briefly covered in most textbooks on astrophysics and cosmology. It is rarely covered as a coherent topic in its own right. When it is discussed the approach is frequently very dry, splitting the teaching into, for example, stars, galaxies and cosmologies, and as a consequence, books lack depth and are rarely comprehensive. Adopting a unique and engaging approach to the subject An Introduction to distance Measurement in Astronomy will take the reader on a journey from the solar neighbourhood to the edge of the Universe, discussing the range of distance measurements methods on the way. The book will focus on the physical processes discussing properties that underlie each method, rather than just presenting a collection of techniques. As well as providing the most compressive account of distance measurements to date, the book will use the common theme of distance measurement to impart basic concepts relevant to a wide variety of areas in astronomy/astrophysics. The book will provide an updated account of the progress made in a large number of subfields in astrophysics, leading to improved distance estimates particularly focusing on the underlying physics. Additionally it will illustrate the pitfalls in these areas and discuss the impact of the remaining uncertainties in the complete understanding of the Universes at large. As a result the book will not only provide a comprehensive study of distance measurement, but also include many recent advances in astrophysics.

"Christopher Wanjek uses a take-no-prisoners approach in debunking the outrageous nonsense being heaped on a gullible public in the name of science and medicine. Wanjek writes with clarity, humor, and humanity, and simultaneously informs and entertains." -Dr. Michael Shermer, Publisher, Skeptic magazine; monthly columnist, Scientific American; author of Why People Believe Weird Things Prehistoric humans believed cedar ashes and incantations could cure a head injury. Ancient Egyptians believed the heart was the center of thought, the liver produced blood, and the brain cooled the body. The ancient Greek physician Hippocrates was a big fan of bloodletting. Today, we are still plagued by countless medical myths and misconceptions. Bad Medicine sets the record straight by debunking widely held yet incorrect notions of how the body works, from cold cures to vaccination fears. Clear, accessible, and highly entertaining, Bad Medicine dispels such medical convictions as: * You only use 10% of your brain: CAT, PET, and MRI scans all prove that there are no inactive regions of the brain . . . not even during sleep. * Sitting too close to the TV causes nearsightedness: Your mother was wrong. Most likely, an already nearsighted child sits close to see better. * Eating junk food will make your face break out: Acne is caused by dead skin cells, hormones, and bacteria, not from a pizza with everything on it. * If you don't dress warmly, you'll catch a cold: Cold viruses are the true and only cause of colds. Protect yourself and the ones you love from bad medicine-the brain you save may be your own.

Most biological science departments run general skills courses for their first years, which include some combination of a range of topics from lab skills, writing and presentation to basic maths, statistics and IT. The IT section of these courses tend to include some internet coverage but the trend towards learning how to find, access, manage and correctly cite online resources is rapidly becoming a required necessity for every student throughout their undergraduate career. At present, there are no internet guides that specifically target this audience, despite the increasing importance placed on the use of online resources and the difficulties students encounter trying to make effective use of the information that is available. There are a lot of resources on the internet and students, especially first years, can feel swamped. As well as needing a guide, students need support to help them identify good, reliable information on the net. They also need guidance in administering the organisation of their searches and the materials that they discover on the internet. This simple guide will help bioscience students to access the information they need on the internet, and to make the most efficient and effective use of their time online.

Advances in computer technology have conveniently coincided with trends in numerical analysis toward increased complexity of computational algorithms based on finite difference methods. It is no longer feasible to perform stability investigation of these methods manually–and no longer necessary. As this book shows, modern computer algebra tools can be combined with methods from numerical analysis to generate programs that will do the job automatically. Comprehensive, timely, and accessible–this is the definitive reference on the application of computerized symbolic manipulations for analyzing the stability of a wide range of difference schemes. In particular, it deals with those schemes that are used to solve complex physical problems in areas such as gas dynamics, heat and mass transfer, catastrophe theory, elasticity, shallow water theory, and more. Introducing many new applications, methods, and concepts, Computer-Aided Analysis of Difference Schemes for Partial Differential Equations * Shows how computational algebra expedites the task of stability analysis–whatever the approach to stability investigation * Covers ten different approaches for each stability method * Deals with the specific characteristics of each method and its application to problems commonly encountered by numerical modelers * Describes all basic mathematical formulas that are necessary to implement each algorithm * Provides each formula in several global algebraic symbolic languages, such as MAPLE, MATHEMATICA, and REDUCE * Includes numerous illustrations and thought-provoking examples throughout the text For mathematicians, physicists, and engineers, as well as for postgraduate students, and for anyone involved with numeric solutions for real-world physical problems, this book provides a valuable resource, a helpful guide, and a head start on developments for the twenty-first century.

Despite all the efforts being put into expanding renewable energy sources, large-scale power stations will be essential as part of a reliable energy supply strategy for a longer period. Given that they are low on CO2 emissions, many countries are moving into or expanding nuclear energy to cover their baseload supply. Building structures required for nuclear plants whose protective function means they are classified as safety-related, have to meet particular construction requirements more stringent than those involved in conventional construction. This book gives a comprehensive overview from approval aspects given by nuclear and construction law, with special attention to the interface between plant and construction engineering, to a building structure classification. All life cycle phases are considered, with the primary focus on execution. Accidental actions on structures, the safety concept and design and fastening systems are exposed to a particular treatment. Selected chapters from the German concrete yearbook are now being published in the new English «Beton-Kalender Series» for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn «Beton-Kalender» has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in «ferro-concrete» structures until – as the book's first editor, Fritz von Emperger (1862-1942), expressed it – the «tempestuous development» in this form of construction came to an end. However, the «Beton-Kalender» quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

Bei den Induktionsmaschinen wurde die Behandlung ohne Vernachlassigung des Standerwicklungswiderstands sowie die Darstellung des Betriebsverhaltens von doppeltgespeisten Maschinen uberarbeitet und erweitert. Die Nomenklatur wurde an die der Bande 'Berechnung elektrischer Maschinen' und 'Theorie elektrischer Maschinen' angepasst.

Wo ist Gott? Die Frage bricht nicht nur dann heraus, wenn man sich den Zustand unserer Welt anschaut. Sie dr?ngt sich schon dort auf, wo nichts Besonderes im Leben passiert. M?sste Gott nicht eigentlich viel ?fter au?ergew?hnlich auftauchen? Stattdessen scheint der eigene Glaube in der Masse an Alltag unterzugehen. Was aber, wenn schon dieses ganz normale Leben ein heiliges ist? Was, wenn der «Himmel auf Erden» mehr ist als nur ein Sprichwort? Sebastian Rink geht in der Bergpredigt auf Spurensuche zum Himmelreich. Er durchforstet die Jesusrede nach dem Heiligen im Leben und findet manch Himmlisches mitten im Alltag.

Comprehensive, authoritative coverage of interferometric techniques for radio astronomy In this Second Edition of Interferometry and Synthesis in Radio Astronomy, three leading figures in the development of large imaging arrays, including very-long-baseline interferometry (VLBI), describe and explain the technology that provides images of the universe with an angular resolution as fine as 1/20,000 of an arcsecond. This comprehensive volume begins with a historical review followed by detailed coverage of the theory of interferometry and synthesis imaging, analysis of interferometer response, geometrical relationships, polarimetry, antennas, and arrays. Discussion of the receiving system continues with analysis of the response to signals and noise, analog design requirements, and digital signal processing. The authors detail special requirements of VLBI including atomic frequency standards, broadband recording systems, and antennas in orbit. Further major topics include: * Calibration of data and synthesis of images * Image enhancement using nonlinear algorithms * Techniques for astrometry and geodesy * Propagation in the neutral atmosphere and ionized media * Radio interference * Related techniques: intensity interferometry, moon occultations, antenna holography, and optical interferometry Interferometry and Synthesis in Radio Astronomy, Second Edition is comprehensive in that it provides an excellent overview of most radio astronomical instrumentation and techniques.
