MRI contrast agents improve visibility of internal body structures. This issue offers a complete, practically focused review of the use of a variety of contrast agents for MR Imaging. A contrast agent not only must be safe, but also efficacious and cost-effective, and the articles in this issue address all three of these concerns and the uses of contrast agents for a variety of applications.
This book is a concise review of the current status and future prospects of concentrating photovoltaic (CPV) technology. Starting with a summary of the current technical and economic status of CPV technology, it identifies the factors that hold CPV back in the commercial market. The main technical areas considered are solar cells, tracking and optics. The solar cells section focuses on spectrum splitting systems, which offer potentially higher efficiency than multi-junction cells with reductions in the manufacturing constraints that lead to high costs. It also offers a brief survey of the latest developments in spectral splitting alongside a discussion of the advances in solar cell manufacturing that aid the development of such systems. Further, it examines electrical design principles for spectral splitting systems that can improve the spectral stability of these systems’ performance. The section on tracking includes a description of tracking integration with an update of the review published in Nature, presenting the latest advances in the field and focusing on surveying conceptual approaches rather than providing an exhaustive description of the literature. The optics section explores 3D printing and other emerging methods of fabricating optics for both prototype and large-scale production, as well as new classes of concentrators, particularly those based on novel photonic materials such as angular filters. Lastly, the authors consider the impact that environmental factors have on the performance of CPV in non-standard environments before concluding with a discussion of the combinations of technologies that they anticipate will most effectively boost CPV in the commercial market.
This book is about the dark photon which is a new gauge boson whose existence has been conjectured. Due to its interaction with the ordinary, visible photon, such a particle can be experimentally detected via specific signatures. In this book, the authors review the physics of the dark photon from the theoretical and experimental point of view. They discuss the difference between the massive and the massless case, highlighting how the two phenomena arise from the same vector portal between the dark and the visible sector. A review of the cosmological and astrophysical observations is provided, together with the connection to dark matter physics. Then, a perspective on current and future experimental limits on the parameters of the massless and massive dark photon is given, as well as the related bounds on milli-charged fermions. The book is intended for graduate students and young researchers who are embarking on dark photon research, and offers them a clear and up-to-date introduction to the subject.
The imposition of strict liability in tort law is controversial, and its theoretical foundations are the object of vigorous debate. Why do or should we impose strict liability on employers for the torts committed by their employees, or on a person for the harm caused by their children, animals, activities, or things? In responding to this type of questions, legal actors rely on a wide variety of justifications. Justifying Strict Liability explores, in a comparative perspective, the most significant arguments that are put forward to justify the imposition of strict liability in four legal systems, two common law, England and the United States, and two civil law, France and Italy. These justifications include: risk, accident avoidance, the 'deep pockets' argument, loss-spreading, victim protection, reduction in administrative costs, and individual responsibility. By looking at how these arguments are used across the four legal systems, this book considers a variety of patterns which characterise the reasoning on strict liability. The book also assesses the justificatory weight of the arguments, showing that these can assume varying significance in the four jurisdictions and that such variations reflect different views as to the values and goals which inspire strict liability and tort law more generally. Overall, the book seeks to improve our understanding of strict liability, to shed light on the justifications for its imposition, and to enhance our understanding of the different tort cultures featuring in the four legal systems studied.
