This 1993 book explores how the 'critical assembly' of scientists at Los Alamos created the first atomic bombs.

This open access book is a unique compilation of experimental benchmark analyses of the accelerator-driven system (ADS) at the Kyoto University Critical Assembly (KUCA) on the most recent advances in the development of computational methods. It is devoted especially to nuclear engineers and scientists. Readers will find a detailed description of advanced measurement techniques and calculation methodologies for the ADS with 14 MeV neutrons and high-energy neutrons (with combined use of 100 MeV protons and Pb-Bi target) at KUCA. Additionally, experimental results of nuclear transmutation of minor actinides by ADS and at a critical state are included. Readers also have access to benchmarks of specific ADS experiments with raw data in the Appendix. The book is a valuable resource for the ADS experiments at KUCA which are globally recognized as both static and kinetic studies from the point of view of fundamental research.

This new collection of essays, commissioned from a range of scholars across the world, takes as its theme the reception of Rome's greatest poet in a time of profound cultural change. Amid the rise of Christianity, the changing status of the city of Rome, and the emergence of new governing classes, Vergil remained a bedrock of Roman education and identity. This volume considers the different ways in which Vergil was read, understood and appropriated; by poets, commentators, Church fathers, orators and historians. The introduction outlines the cultural and historical contexts. Twelve chapters dedicated to individual writers or genres, and the contributors make use of a wide range of approaches from contemporary reception theory. An epilogue concludes the volume.

A fundamental resource for understanding and developing effective self-assembly and nanotechnology systems Systematically integrating self-assembly, nanoassembly, and nanofabrication into one easy-to-use source, Self-Assembly and Nanotechnology Systems effectively helps students, professors, and researchers comprehend and develop applicable techniques for use in the field. Through case studies, countless examples, clear questions, and general applications, this book provides experiment-oriented techniques for designing, applying, and characterizing self-assembly and nanotechnology systems. Self-Assembly and Nanotechnology Systems includes: * Techniques for identifying assembly building units * Practical assembly methods to focus on when developing nanomaterials, nanostructures, nanoproperties, nanofabricated systems, and nanomechanics * Algorithmic diagrams in each chapter for a general overview * Schematics designed to link assembly principles with actual systems * Hands-on lab activities This informative reference also analyzes the diverse origins and structures of assembly building units, segmental analysis, and selection of assembly principles, methods, characterization techniques, and predictive models. Complementing the author's previous conceptually based book on this topic, Self-Assembly and Nanotechnology Systems is a practical guide that grants practitioners not only the skills to properly analyze assembly building units but also how to work with applications to exercise and develop their knowledge of this rapidly advancing scientific field.

In recent years "leaderless" social movements have proliferated around the globe, from North Africa and the Middle East to Europe, the Americas, and East Asia. Some of these movements have led to impressive gains: the toppling of authoritarian leaders, the furthering of progressive policy, and checks on repressive state forces. They have also been, at times, derided by journalists and political analysts as disorganized and ineffectual, or suppressed by disoriented and perplexed police forces and governments who fail to effectively engage them. Activists, too, struggle to harness the potential of these horizontal movements. Why have the movements, which address the needs and desires of so many, not been able to achieve lasting change and create a new, more democratic and just society? Some people assume that if only social movements could find new leaders they would return to their earlier glory. Where, they ask, are the new Martin Luther Kings, Rudi Dutschkes, and Stephen Bikos? With the rise of right-wing political parties in many countries, the question of how to organize democratically and effectively has become increasingly urgent. Although today's leaderless political organizations are not sufficient, a return to traditional, centralized forms of political leadership is neither desirable nor possible. Instead, as Michael Hardt and Antonio Negri argue, familiar roles must be reversed: leaders should be responsible for short-term, tactical action, but it is the multitude that must drive strategy. In other words, if these new social movements are to achieve meaningful revolution, they must invent effective modes of assembly and decision-making structures that rely on the broadest democratic base. Drawing on ideas developed through their well-known Empire trilogy, Hardt and Negri have produced, in Assembly, a timely proposal for how current large-scale horizontal movements can develop the capacities for political strategy and decision-making to effect lasting and democratic change. We have not yet seen what is possible when the multitude assembles.
