Stereophonica: Sound and Space in Science, Technology, and the Arts
by Gascia OuzounianEpisodes in the transformation of our understanding of sound and space, from binaural listening in the nineteenth century to contemporary sound art.The relationship between sound and space has become central to both creative practices in music and sound art and contemporary scholarship on sound. Entire subfields have emerged in connection to the spatial aspects of sound, from spatial audio and sound installation to acoustic ecology and soundscape studies. But how did our understanding of sound become spatial? In Stereophonica, Gascia Ouzounian examines a series of historical episodes that transformed ideas of sound and space, from the advent of stereo technologies in the nineteenth century to visual representations of sonic environments today.Developing a uniquely interdisciplinary perspective, Ouzounian draws on both the history of science and technology and the history of music and sound art. She investigates the binaural apparatus that allowed nineteenth-century listeners to observe sound in three dimensions; examines the development of military technologies for sound location during World War I; revisits experiments in stereo sound at Bell Telephone Laboratories in the 1930s; and considers the creation of "optimized acoustical environments" for theaters and factories. She explores the development of multichannel "spatial music" in the 1950s and sound installation art in the 1960s; analyzes the mapping of soundscapes; and investigates contemporary approaches to sonic urbanism, sonic practices that reimagine urban environments through sound.Rich in detail but accessible and engaging, and generously illustrated with photographs, drawings, maps, and diagrams of devices and artworks, Stereophonica brings an acute, imaginative, and much-needed historical sensibility to the growing literature around sound and space.

Stereoselective Desymmetrization Methods in the Assembly of Complex Natural Molecules
by Robert. J SharpeThis thesis describes the inception, design, and implementation of stereoselective desymmetrization reactions in the total synthesis of the natural products pactamycin and paspaline. In the case of pactamycin, the author develops a novel asymmetric Mannich reaction and symmetry-breaking reduction strategy to enable facile construction of the complex core architecture in fifteen steps using commercially available materials - the shortest synthesis to date. He subsequently demonstrates the flexibility of this approach in SAR investigations by highlighting the preparation of twenty-five unique pactamycin structural congeners. For paspaline, the author develops a biocatalytic desymmetrization strategy that allows the highly controlled synthesis of core stereochemistry and provides a platform for the development of new conceptual disconnections in the synthesis of "steroid-like" natural products. This thesis offers a valuable resource for students embarking on a PhD in total synthesis.

Stereoselective Heterocycle Synthesis via Alkene Difunctionalization
by David A. PetroneThis book investigates the use of palladium modified by bulky ligands as catalysts for new chemical transformations that rapidly assemble several classes of complex heterocyles. It documents the development of new chemical reactions involving carbon–carbon (C‒C) and carbon–halogen (C‒X) bond formation in the context of alkene difunctionalization and dearomatization reactions. Due to the ubiquity of heterocycles in bioactive natural products and life-improving pharmaceutical treatments, a long-term goal for synthetic organic chemists has been to develop novel and creative heterocycle syntheses that illicit a high degree of product diversity and are characterized by mild reaction conditions and limited waste production. A considerable fraction of leading pharmaceutical drugs contain at least one heterocycle within their chemical structure, and their prevalence in these technologies is strong evidence that the fundamental curiosities of organic chemistry lead to real-world solutions for the health and wellness of the global population.

Stereotactic Radiosurgery for the Treatment of Central Nervous System Meningiomas
by Michele Longhi Enrico D. F. Motti Antonio Nicolato Piero PicozziMeningiomas are the most frequently reported neuro-oncologic condition, accounting for 12% to 30% of all primary intracranial tumors. The first case of intracranial meningioma treated with stereotactic radiosurgery was reported by Backlund E-O in 1971. Since then, more than 200,000 meningiomas have been treated with stereotactic radiosurgery worldwide to date. The large number of patients treated using this method is due to the fact that meningiomas are frequently located in critical areas and microsurgery is often associated with severe and permanent neurological complications.This book discusses the advantages, risks and limits of stereotactic radiosurgery relating to all regions of interest for a neuroradiosurgical approach for the treatment of central nervous system meningiomas. Firstly, it presents an introduction focusing on the “state of the art”. It then discusses the physics, imaging, neurological and neuro-oncological issues in multidisciplinary management. Lastly, it features a summary of results, including the most recent published papers regarding all the locations involved in the stereotactic radiosurgery treatment as well as new approaches to meningiomas, with particular reference to the hypofrationated treatments. Intended for anyone involved in the neuroradiosurgical treatment of brain diseases, the book provides an up-to-date overview of the latest stereotactic radiosurgery treatment of central nervous system meningiomas.
Stereotypic Animal Behaviour: Fundamentals and Applications to Welfare
by Georgia Mason Jeffrey RushenAbnormal behavior patterns, from the jumping and somersaulting of caged laboratory mice to the pacing of enclosed 'big cats', are displayed by many millions of farm, zoo, research and companion animals. Including new chapters and over 30 contributors, this book focuses on the causation and treatment of these environment-induced stereotypic behaviors, and their implications for animal welfare and normalcy of brain functioning. The book begins by taking an ethological perspective, focusing on the constraints captivity places on animals' normal behavioral repertoires, and the effects these have on specific motivational systems. It then addresses the role of dysfunction, particularly the impact of chronic stress and impoverished environments on brain functioning. The book then moves on to explore how stereotypic behaviors can be tackled, once they have emerged, using diverse techniques from environmental enrichment to pharmaceutical intervention. It concludes by giving a new definition for 'stereotypic behavior', and a discussion of future research directions.

Steric Effects in the Chemisorption of Vibrationally Excited Methane on Nickel
by Bruce L. YoderBruce Yoder's thesis outlines his investigation of the dissociative chemisorption of methane (CH4) on a nickel single crystal. In this work Bruce uses a molecular beam and infrared laser techniques to prepare methane in excited rovibrational states. The excited methane molecules are aligned relative to the target nickel surface. Bruce describes the discovery and exploration of a previously unknown steric effect in the dissociation reaction between a vibrationally excited methane molecule and a nickel crystal. From these studies we see that methane molecules are up to twice as reactive when the vibration is aligned parallel rather than perpendicular to the surface. This discovery will help guide the development of detailed predictive models of methane chemisorption, which in turn may lead to better catalysts for the synthesis of several industrially relevant chemicals, including hydrogen fuel from natural gas.
