Hygrothermal Risk on Building Heritage

by João M. P. Q. Delgado Ana Sofia Guimarães Vasco Peixoto Freitas

This book presents a critical review of a criterion of risk, created to assess the flood risk to heritage buildings, and evaluates this criterion by applying it to the sample Portuguese heritage buildings. In a first approach, the total number of potential parameters is effectively reduced and the selected criteria are divided into two different groups: the monument's location in relation to a waterway, and the behaviour of its construction material in contact with water. Above all, the book discusses the importance of architectural heritage and argues for the need to safeguard it from extreme climatic phenomena such as floods. As such, the book vividly reminds the scientific community that the intensification of the global warming and climate change will worsen throughout the 21st century, and that it is therefore necessary to adopt preventive measures to minimize, mitigate and control these adverse effects if we hope to avoid catastrophic consequences. At the same time, the book takes into account a broad range of scientific and engineering disciplines, such as civil engineering and architecture, offering a synthesis of the current state of knowledge to benefit and guide experts and practitioners in related fields.

Hylomorphism into Pieces: Elements, Atoms, and Corpuscles in Natural Philosophy and Medicine, 1400–1600 (Palgrave Studies in Medieval and Early Modern Medicine)

by Nicola Polloni Sylvain Roudaut

Focussing on late medieval and early modern philosophy and medicine, this edited collection explores the replacement of hylomorphism—the dominant theory of bodies in the Middle Ages—with new theories of matter such as corpuscularianism and atomism at the dawn of the Modern period. Together, the contributions offer a comprehensive overview of a crucial historical moment for the history of philosophy and science: the rise of a new conception of matter against declining scholastic theories. They highlight the key aspects of this historical transition by investigating precise concepts that were central to this shift, namely the notions of elements, atoms, and corpuscles. Shedding light on the gradual process by which hylomorphism was eventually replaced by a more positive conception of matter and natural processes, the book demonstrates how many thinkers of the late medieval period were willing to integrate new theories into the conceptual framework of Aristotelian natural philosophy, and tried to harmonise them with the traditional concepts and axioms of scholastic doctrines. Showing how these conceptual innovations resulted from a complex interaction between different fields of late medieval and early modern knowledge, the authors bring together research from the disciplines of metaphysics, medieval philosophy, and medical science. Providing an overview of an important theoretical shift in the transition from the Middle Ages to the Modern Era, this book is essential reading for scholars of philosophy, and historians of medieval and early modern science and medicine.

Hymenoptera and Conservation

by T. R. New

Hymenoptera, the bees, wasps and ant, are one of the largest insect orders, and have massive ecological importance as pollinators and as predators or parasitoids of other insects. These roles have brought them forcefully to human notice , as governors of some key ecological services that strongly influence human food supply. Recent declines of pollinators and introductions of alien pests or biological control agents are only part of the current concerns for conservation of Hymenoptera, and of the interactions in which they participate in almost all terrestrial ecosystems. Both pests and beneficial species abound within the order, sometimes closely related within the same families. Many taxa are both difficult to identify, and very poorly known. This global overview, the first such account for the whole of the Hymenoptera, discusses a broad range of themes to introduce the insects and their conservation roles and needs, and how their wellbeing may be approached. The book is intended as a source of information for research workers, students, conservation managers and naturalists as an introduction to the importance of this dominant insect order.

Hymn of the Universe

by Pierre Teilhard De Chardin

In this book it is almost always Pere Teilhard, the man of prayer rather than the man of science, who speaks to us. As Sir Julian Huxley wrote of The Mass on the World, it is a 'truly poetical essay ... at one and the same time mystical and realistic, religious and philosophical'. This does not mean, of course, that the author ever forgets or betrays his science; what it does mean is: that the reader's approach, and response, to these pages must of necessity be quite different from those demanded by the scientific works. The mystic, the poet use language in a way essentially different from that of the scientist.

Hypatia von Alexandria

by Laurel A. Rockefeller

Als die westliche Welt in Dunkelheit versank, wagte sie, das Licht zu verteidigen. Geboren im Jahr 355 der christlichen Zeitrechnung, im Nachhall von Konstantins Regierung, lebte Hypatia von Alexandria in einem zusammenbrechenden Römischen Reich. In einer Welt, in der der Gehorsam gegen religiöse Autoritäten über die Wissenschaft triumphierte, in der Logik und Verstand die neue Weltordnung bedrohten. Es war eine Welt an der Grenze zum düsteren Mittelalter, eine Welt, die über die Fragen Wissenschaft gegen Religion, Freiheit gegen Strenggläubigkeit, Toleranz gegen Hass entschied. Über vierzig Jahre stand Hypatia zwischen dem dunklen Zeitalter und dem Licht der Philosophie, Künste und Wissenschaft. Auch wenn keines ihrer Werke die offensive Bücherverbrennung religiöser Fanatiker überdauert hat, so bleibt doch ihr Vermächtnis als eine der größten Gelehrten aller Zeiten. Dies ist ihre faszinierende und wahre Geschichte. Das Buch beinhaltet außerdem eine Bibliografie, eine detaillierte Zeitleiste und die Längen- und Breitengrade ausgewählter Städte des Römischen Reiches, sodass Sie die Wunder des Himmels gemeinsam mit Hypatia erkunden können.

Hyper-specializing in Saxophone Using Acoustical Insight and Deep Listening Skills (Current Research in Systematic Musicology #6)

by Jonas Braasch

This book presents a novel method of grafting musical wind instruments by exchanging an instrument’s standard mouthpiece with different tone generators. Using the concrete example of the soprano saxophone, it describes how, with six other tone generators, including brass, double reed, and free reed mechanisms, the saxophone can be extended to nearly every wind instrument category in the von Hornbostel and Sachs classification system. The book demonstrates how it is possible to play these instrument variations with high proficiency, and describes the method of hyper-specialization, including acoustical insights, conservatory training methods and the underlying philosophy. The latter is based on the cultural traditions of the different wind instrument prototypes and the Deep Listening philosophy of cultivating internal diversity, and approach that leads to a new level of wind instrument virtuosity that offers great timbral variety combined with the flexibility of a regular acoustic wind instrument.

Hyper-Velocity Impacts on Rubble Pile Asteroids

by Jakob Deller

The thesis presents a tool to create rubble pile asteroid simulants for use in numerical impact experiments, and provides evidence that the asteroid disruption threshold and the resultant fragment size distribution are sensitive to the distribution of internal voids. This thesis represents an important step towards a deeper understanding of fragmentation processes in the asteroid belt, and provides a tool to infer the interior structure of rubble pile asteroids. Most small asteroids are 'rubble piles' - re-accumulated fragments of debris from earlier disruptive collisions. The study of fragmentation processes for rubble pile asteroids plays an essential part in understanding their collisional evolution. An important unanswered question is "what is the distribution of void space inside rubble pile asteroids?" As a result from this thesis, numerical impact experiments can now be used to link surface features to the internal structure and therefore help to answer this question. Applying this model to asteroid Steins, which was imaged from close range by the Rosetta spacecraft, a large hill-like structure is shown to be most likely primordial, while a catena of pits can be interpreted as evidence for the existence of fracturing of pre-existing internal voids.

Here we combine an overview of various modelling approaches for collective behaviours displayed by individuals/cells/bacteria that interact locally and non-locally, with analytical and numerical mathematical techniques that can be used to investigate the spatio-temporal patterns produced by said individuals/cells/bacteria. Richly illustrated, the book offers a valuable guide for researchers new to the field, and is also suitable as a textbook for senior undergraduate or graduate students in mathematics or related disciplines.

Hyperbolic Triangle Centers: The Special Relativistic Approach

by A. A. Ungar

After A. Ungar had introduced vector algebra and Cartesian coordinates into hyperbolic geometry in his earlier books, along with novel applications in Einstein's special theory of relativity, the purpose of his new book is to introduce hyperbolic barycentric coordinates, another important concept to embed Euclidean geometry into hyperbolic geometry. It will be demonstrated that, in full analogy to classical mechanics where barycentric coordinates are related to the Newtonian mass, barycentric coordinates are related to the Einsteinian relativistic mass in hyperbolic geometry. Contrary to general belief, Einstein's relativistic mass hence meshes up extraordinarily well with Minkowski's four-vector formalism of special relativity. In Euclidean geometry, barycentric coordinates can be used to determine various triangle centers. While there are many known Euclidean triangle centers, only few hyperbolic triangle centers are known, and none of the known hyperbolic triangle centers has been determined analytically with respect to its hyperbolic triangle vertices. In his recent research, the author set the ground for investigating hyperbolic triangle centers via hyperbolic barycentric coordinates, and one of the purposes of this book is to initiate a study of hyperbolic triangle centers in full analogy with the rich study of Euclidean triangle centers. Owing to its novelty, the book is aimed at a large audience: it can be enjoyed equally by upper-level undergraduates, graduate students, researchers and academics in geometry, abstract algebra, theoretical physics and astronomy. For a fruitful reading of this book, familiarity with Euclidean geometry is assumed. Mathematical-physicists and theoretical physicists are likely to enjoy the study of Einstein's special relativity in terms of its underlying hyperbolic geometry. Geometers may enjoy the hunt for new hyperbolic triangle centers and, finally, astronomers may use hyperbolic barycentric coordinates in the velocity space of cosmology.

Hypercarbon Chemistry

by George A. Olah G. K. Surya Prakash Robert E. Williams Kenneth Wade Árpád Molnár

The essential new edition of the book that put hypercarbon chemistry on the map A comprehensive and contemporary treatment of the chemistry of hydrocarbons (alkanes, alkenes, alkynes, and aromatics) towards electrophiles, Hypercarbon Chemistry, Second Edition deals with all major aspects of such chemistry involved in hydrocarbon transformations, and of the structural and reaction chemistry of carboranes, mixed hydrides in which both carbon and boron atoms participate in the polyhedral molecular frameworks. Despite the firmly established tetravalency, carbon can bond simultaneously to five or more other atoms. "Hypercarbon" bonding permeates much organic, inorganic and organometallic chemistry, and the book serves as the compendium for this phenomenon. Copious diagrams illustrate the rich variety of hypercarbon structures now known, and patterns therein. Individual chapters deal with specific categories of compound (e. g. organometallics, carboranes, carbocations) or transformations that proceed through transient hypercarbon species, detailing fundamental chemistry, including reactivity, selectivity, stereochemistry, mechanistic factors and more.
