Neuware - It is becoming increasingly clear that our modern technological society is vulnerable to the impacts of severe solar storms, as well as radiation, particle and geomagnetic disturbances. However, the potential severity of these extreme solar events and their probability of occurring are unknown. What can we expect from the Sun What could the most severe solar particle storms look like Does the Sun have an unlimited ability to produce severe storms Can a destructive 'black swan' event occur Direct solar data covers only several decades, a period too short to answer these questions. Fortunately, other indirect ways to study these, possibly rare, extreme solar storms have been discovered, paving the way for analysis of these events on the multi-millennial timescale. At present, studies of extreme solar events are growing, forming a new research discipline. This book, written by leaders in the corresponding aspects of the field, presents a first systematic review of the current state of the art.…

Taschenbuch. Condizione: Neu. Neuware - The redshifted 21-cm signal is set to transform astrophysical cosmology, bringing a historically data-starved field into the era of Big Data. Corresponding to the spin-flip transition of neutral hydrogen, the 21-cm line is sensitive to the temperature and ionization state of the cosmic gas, as well as to cosmological parameters. Crucially, with the development of new interferometers, it will allow us to map out the first billion years of our universe, enabling us to learn about the properties of the unseen first generations of galaxies. Rapid progress is being made on both the observational and theoretical fronts, and important decisions on techniques and future direction are being made. The Cosmic 21-cm Revolution gathers contributions from current leaders in this fast-moving field, providing both an overview for graduate students and a reference point for current researchers.…

Taschenbuch. Condizione: Neu. Neuware - X-ray diagnostic or interventional examinations are needed during pregnancy to provide information for significant medical problems and emergency situations. When this occurs, it is important to follow the right steps to minimize conceptus radiation dose. Occasionally, pregnant patients are also exposed accidentally to X-rays. These patients need different dose management in comparison with those exposed intentionally. Furthermore, proper dose management is needed for pregnant staff working with X-rays. Additionally, the dose management of paediatric patients undergoing radiology procedures requires special attention because children are especially vulnerable to X-rays. They have longer life expectancy to develop radiogenic health effects and they receive a higher radiation dose than necessary if the acquisition protocol is not adjusted to their small body size.This book reflects the broad advances that have been made in the field of medical dosimetry and medical radiation protection, and it provides information about the practical use of new information in radiation dose management of pregnant patients, pregnant staff and paediatric patients in diagnostic and interventional radiology. It is suitable for students, lecturers, researchers and practitioners interested in the fields of medical dosimetry, medical radiation protection and diagnostic and interventional radiology. …

Each chapter consists of a series of questions typical of those found on the fellowship exams. The images and diagrams that accompany each question provide a stimulus to the concepts being challenged, whilst the answers also contain explanations that, in many instances, go beyond that strictly necessary to support the answer. Examination tips to better prepare readers are also included.…

Buch. Condizione: Neu. Neuware - Extragalactic Novae: A historical perspective takes the reader on a journey chronicling the study of a class of eruptive variable stars known as 'Novae Stella', Latin for 'New Stars'. These mysterious transient objects, now referred to simply as novae, have been recognized since antiquity, suddenly appearing in the night sky before slowly fading back into obscurity. The book begins with a brief introduction to the early observations, including an overview of the role that novae played in the birth of extragalactic astronomy, and concludes with a discussion of how nova observations over the past century have contributed to our knowledge of close binary star populations in nearby galaxies. Along the way, the history of our understanding of the nova phenomena, in the Milky Way and beyond, is unveiled. In particular, the author describes how the enigmatic nova eruptions were finally realized to be the result of thermonuclear runaways on the surfaces of accreting white dwarf stars, how a controversial correlation between a nova's peak luminosity and its rate of decline (the MMRD relation) has been used in extragalactic distance determinations, and how recent observations have bolstered the case that novae may form a significant channel for the production of type Ia supernovae. These topics, and more, are recounted by an observer who has spent the past 35 years studying these fascinating objects.…
