Book excerpt: This title was first published in 2000: The theme of this collection of essays is "technology transfer". The topic has three major aspects: the interchange of technologies between military and civilian applications - "spin-off", "dual use", "conversion" and "diversification" fall under this heading; the proliferation of military arms, which could occur either through arms races between developed nations or through the transfer of military technology from developed arms industries to less developed nations - "proliferation", "arms races" and "arms control agreements" fall under this heading; and the transfer of civilian technologies from developing nations to less developed nations. The expression, "North-South transfer" and the idea of "development" come under this final section. The essays offer examination of all three aspects.

Download or read book Modelling Learners and Learning in Science Education written by Keith S. Taber and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book sets out the necessary processes and challenges involved in modeling student thinking, understanding and learning. The chapters look at the centrality of models for knowledge claims in science education and explore the modeling of mental processes, knowledge, cognitive development and conceptual learning. The conclusion outlines significant implications for science teachers and those researching in this field. This highly useful work provides models of scientific thinking from different field and analyses the processes by which we can arrive at claims about the minds of others. The author highlights the logical impossibility of ever knowing for sure what someone else knows, understands or thinks, and makes the case that researchers in science education need to be much more explicit about the extent to which research onto learners’ ideas in science is necessarily a process of developing models. Through this book we learn that research reports should acknowledge the role of modeling and avoid making claims that are much less tentative than is justified as this can lead to misleading and sometimes contrary findings in the literature. In everyday life we commonly take it for granted that finding out what another knows or thinks is a relatively trivial or straightforward process. We come to take the ‘mental register’ (the way we talk about the ‘contents’ of minds) for granted and so teachers and researchers may readily underestimate the challenges involved in their work.
Download or read book Nuclear Physics written by National Research Council and published by National Academies Press. This book was released on 2013-02-25 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal goals of the study were to articulate the scientific rationale and objectives of the field and then to take a long-term strategic view of U.S. nuclear science in the global context for setting future directions for the field. Nuclear Physics: Exploring the Heart of Matter provides a long-term assessment of an outlook for nuclear physics. The first phase of the report articulates the scientific rationale and objectives of the field, while the second phase provides a global context for the field and its long-term priorities and proposes a framework for progress through 2020 and beyond. In the second phase of the study, also developing a framework for progress through 2020 and beyond, the committee carefully considered the balance between universities and government facilities in terms of research and workforce development and the role of international collaborations in leveraging future investments. Nuclear physics today is a diverse field, encompassing research that spans dimensions from a tiny fraction of the volume of the individual particles (neutrons and protons) in the atomic nucleus to the enormous scales of astrophysical objects in the cosmos. Nuclear Physics: Exploring the Heart of Matter explains the research objectives, which include the desire not only to better understand the nature of matter interacting at the nuclear level, but also to describe the state of the universe that existed at the big bang. This report explains how the universe can now be studied in the most advanced colliding-beam accelerators, where strong forces are the dominant interactions, as well as the nature of neutrinos.
Download or read book Inertial Electrostatic Confinement IEC Fusion written by George H. Miley and published by Springer Science & Business Media. This book was released on 2013-12-12 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with an introductory understanding of Inertial Electrostatic Confinement (IEC), a type of fusion meant to retain plasma using an electrostatic field. IEC provides a unique approach for plasma confinement, as it offers a number of spin-off applications, such as a small neutron source for Neutron Activity Analysis (NAA), that all work towards creating fusion power. The IEC has been identified in recent times as an ideal fusion power unit because of its ability to burn aneutronic fuels like p-B11 as a result of its non-Maxwellian plasma dominated by beam-like ions. This type of fusion also takes place in a simple mechanical structure small in size, which also contributes to its viability as a source of power. This book posits that the ability to study the physics of IEC in very small volume plasmas makes it possible to rapidly investigate a design to create a power-producing device on a much larger scale. Along with this hypothesis the book also includes a conceptual experiment proposed for demonstrating breakeven conditions for using p-B11 in a hydrogen plasma simulation. This book also: Offers an in-depth look, from introductory basics to experimental simulation, of Inertial Electrostatic Confinement, an emerging method for generating fusion power Discusses how the Inertial Electrostatic Confinement method can be applied to other applications besides fusion through theoretical experiments in the text Details the study of the physics of Inertial Electrostatic Confinement in small-volume plasmas and suggests that their rapid reproduction could lead to the creation of a large-scale power-producing device Perfect for researchers and students working with nuclear fusion, Inertial Electrostatic Confinement (IEC) Fusion: Fundamentals and Applications also offers the current experimental status of IEC research, details supporting theories in the field and introduces other potential applications that stem from IEC.

Download or read book Abolishing Nuclear Weapons written by George Perkovich and published by Routledge. This book was released on 2017-10-03 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear disarmament is firmly back on the international agenda. But almost all current thinking on the subject is focused on the process of reducing the number of weapons from thousands to hundreds. This rigorous analysis examines the challenges that exist to abolishing nuclear weapons completely, and suggests what can be done now to start overcoming them. The paper argues that the difficulties of 'getting to zero' must not preclude many steps being taken in that direction. It thus begins by examining steps that nuclear-armed states could take in cooperation with others to move towards a world in which the task of prohibiting nuclear weapons could be realistically envisaged. The remainder of the paper focuses on the more distant prospect of prohibiting nuclear weapons, beginning with the challenge of verifying the transition from low numbers to zero. It moves on to examine how the civilian nuclear industry could be managed in a nuclear-weapons-free world so as to prevent rearmament. The paper then considers what political-security conditions would be required to make a nuclear-weapons ban enforceable and explores how enforcement might work in practice. Finally, it addresses the latent capability to produce nuclear weapons that would inevitably exist after abolition, and asks whether this is a barrier to disarmament, or whether it can be managed to meet the security needs of a world newly free of the bomb.
