Mössbauer Spectroscopy
by Guido Langouche Yutaka YoshidaTutorials on Mössbauer Spectroscopy Since the discovery of the Mössbauer Effect many excellent books have been published for researchers and for doctoral and master level students. However, there appears to be no textbook available for final year bachelor students, nor for people working in industry who have received only basic courses in classical mechanics, electromagnetism, quantum mechanics, chemistry and materials science. The challenge of this book is to give an introduction to Mössbauer Spectroscopy for this level. The ultimate goal of this book is to give this audience not only a scientific introduction to the technique, but also to demonstrate in an attractive way the power of Mössbauer Spectroscopy in many fields of science, in order to create interest among the readers in joining the community of Mössbauer spectroscopists. This is particularly important at times where in many Mössbauer laboratories succession is at stake. This book will be used as a textbook for the tutorial sessions, organized at the occasion of the 2011 International Conference on the Application of Mössbauer Spectroscopy (ICAME2011) in Tokyo.

N-Heterocyclic Carbenes in Transition Metal Catalysis and Organocatalysis
by Catherine S.J. CazinN-Heterocyclic Carbenes in Transition Metal Catalysis and Organocatalysis features all catalytic reactions enabled by N-heterocyclic carbenes (NHCs), either directly as organocatalysts or as ligands for transition metal catalysts. An explosion in the use of NHCs has been reported in the literature during the past seven years making this comprehensive overview highly apropos. The book begins with an introductory overview of NHCs which could have been subtitled all you need to know about NHCs. The main body of the book is dedicated to applications of NHCs in catalysis. In addition to the success stories of NHCs in metathesis, NHCs in cross coupling and more recently NHCs in organocatalysis, all other less publicized areas are also covered. As the success of NHCs is generally attributed to their potential to stabilize metal centres, the inclusion of a chapter on the decomposition of NHC catalysts is pertinent. The book closes with a chapter describing the applications of NHCs in industrial processes, which is the first coverage of its kind, and brings a unique industrial context to this book. Included in this book: Historical aspects of NHCsSynthetic pathways to NHC precursors, free NHCs and complexesMethods of characterisation of NHCs and related complexesElectronic properties of NHCsSteric properties of NHCs and models for their descriptionNHCs for metathesis and cross-coupling reactionsNHCs as organocatalystsNHC Transition-Metal mediated oxidations, additions to multiple bonds, polymerisation and oligomerisation, cyclisations, direct arylations, reactions involving CO, C-F and C-H bond activation, ...Decomposition of NHC-containing catalystsIndustrial applications involving NHC-containing catalystsN-Heterocyclic Carbenes in Transition Metal Catalysis and Organocatalysis provides a fresh view of NHCs since most contributors are young emerging researchers in the field of homogeneous catalysis using NHCs.

N=2 Supersymmetric Dynamics for Pedestrians
by Yuji TachikawaUnderstanding the dynamics of gauge theories is crucial, given the fact that all known interactions are based on the principle of local gauge symmetry. Beyond the perturbative regime, however, this is a notoriously difficult problem. Requiring invariance under supersymmetry turns out to be a suitable tool for analyzing supersymmetric gauge theories over a larger region of the space of parameters. Supersymmetric quantum field theories in four dimensions with extended N=2 supersymmetry are further constrained and have therefore been a fertile field of research in theoretical physics for quite some time. Moreover, there are far-reaching mathematical ramifications that have led to a successful dialogue with differential and algebraic geometry. These lecture notes aim to introduce students of modern theoretical physics to the fascinating developments in the understanding of N=2 supersymmetric gauge theories in a coherent fashion. Starting with a gentle introduction to electric-magnetic duality, the author guides readers through the key milestones in the field, which include the work of Seiberg and Witten, Nekrasov, Gaiotto and many others. As an advanced graduate level text, it assumes that readers have a working knowledge of supersymmetry including the formalism of superfields, as well as of quantum field theory techniques such as regularization, renormalization and anomalies. After his graduation from the University of Tokyo, Yuji Tachikawa worked at the Institute for Advanced Study, Princeton and the Kavli Institute for Physics and Mathematics of the Universe. Presently at the Department of Physics, University of Tokyo, Tachikawa is the author of several important papers in supersymmetric quantum field theories and string theory.

NASA and the Politics of Climate Research: Satellites and Rising Seas (Palgrave Studies in the History of Science and Technology)
by W. Henry LambrightToday, there exists an integrated, large-scale satellite system to track sea-level rise, its speed, causes, and impacts. Building it was a struggle every step of the way. It was the most vivid and potentially consequential program within NASA’s larger Earth Science directorate. How did it happen? Who did what? Why? This book seeks to answer such questions. It goes back to the origins of NASA’s interest in the oceans in the 1960s and first true ocean satellite, Seasat, in 1978. After three months of operation, Seasat failed. But before it did, it showed how much satellites could tell about the ocean’s dynamics. In many ways, sea-level rise is the clearest and most understandable result of a warming planet.
NASA and the Space Industry (New Series in NASA History)
by Joan Lisa BrombergFew federal agencies have more extensive ties to the private sector than NASA. NASA's relationships with its many aerospace industry suppliers of rocket engines, computers, electronics, gauges, valves, O-rings, and other materials have often been described as "partnerships." These have produced a few memorable catastrophes, but mostly technical achievements of the highest order. Until now, no one has written extensively about them.In NASA and the Space Industry, Joan Lisa Bromberg explores how NASA's relationship with the private sector developed and how it works. She outlines the various kinds of expertise public and private sectors brought to the tasks NASA took on, describing how this division of labor changed over time. She explains why NASA sometimes encouraged and sometimes thwarted the privatization of space projects and describes the agency's role in the rise of such new space industries as launch vehicles and communications satellites.

NASA's BEYOND EINSTEIN PROGRAM: AN ARCHITECTURE FOR IMPLEMENTATION
by National Research Council of the National AcademiesThe Beyond Einstein (BE) program is a set of five space missions designed to address important questions about physics and astrophysics. In 2003, NASA prepared a research roadmap proposing these five missions in order to study dark energy, black holes, gravitational radiation, inflation of the early universe, and Einstein’s theory of gravitation. In FY2007, congressional language prompted NASA and DOE to request the NRC to assess these missions and recommend which to develop and launch first using a funding wedge that will start in 2009. This report provides, for each mission, an analysis of its scientific impact, an examination of technical risk and a cost assessment, and a review of related policy and programmatic issues. The report concludes with recommendations to guide the programs development.
