Calculating X-ray Tube Spectra - Pedro Andreo - Bog - Taylor & Francis Ltd - Plusbog.dk

Calculating X-ray Tube Spectra - Pedro Andreo - Bog - Taylor & Francis Ltd - Plusbog.dk

Calculating x-ray tube spectra provides a comprehensive review of the modelling of x-ray tube emissions, with a focus on medical imaging and radiotherapy applications. It begins by covering the relevant background, before discussing modelling approaches, including both analytical formulations and Monte Carlo simulation. Historical context is provided, based on the past century of literature, as well as a summary of recent developments and insights. The book finishes with example applications for spectrum models, including beam quality prediction and the calculation of dosimetric and image-quality metrics. This book will be a valuable resource for postgraduate and advanced undergraduate students studying medical radiation physics, in addition to those in teaching, research, industry and healthcare settings whose work involves x-ray tubes. Key Features: - Covers simple modelling approaches as well as full Monte Carlo simulation of x-ray tubes. - Bremsstrahlung and characteristic contributions to the spectrum are discussed in detail. - Learning is supported by free open-source software and an online repository of code. An online repository of the code that accompanies this book can be found here: https://bitbucket.org/caxtus

Semiconductor X-Ray Detectors - B. G. Lowe - Bog - Taylor & Francis Ltd - Plusbog.dk

Semiconductor X-Ray Detectors - B. G. Lowe - Bog - Taylor & Francis Ltd - Plusbog.dk

Identifying and measuring the elemental x-rays released when materials are examined with particles (electrons, protons, alpha particles, etc.) or photons (x-rays and gamma rays) is still considered to be the primary analytical technique for routine and non-destructive materials analysis. The Lithium Drifted Silicon (Si(Li)) X-Ray Detector, with its good resolution and peak to background, pioneered this type of analysis on electron microscopes, x-ray fluorescence instruments, and radioactive source- and accelerator-based excitation systems. Although rapid progress in Silicon Drift Detectors (SDDs), Charge Coupled Devices (CCDs), and Compound Semiconductor Detectors, including renewed interest in alternative materials such as CdZnTe and diamond, has made the Si(Li) X-Ray Detector nearly obsolete, the device serves as a useful benchmark and still is used in special instances where its large, sensitive depth is essential. Semiconductor X-Ray Detectors focuses on the history and development of Si(Li) X-Ray Detectors, an important supplement to the knowledge now required to achieve full understanding of the workings of SDDs, CCDs, and Compound Semiconductor Detectors. The book provides an up-to-date review of the principles, practical applications, and state of the art of semiconductor x-ray detectors. It describes many of the facets of x-ray detection and measurement using semiconductors, from manufacture to implementation. The initial chapters present a self-contained summary of relevant background physics, materials science, and engineering aspects. Later chapters compare and contrast the assembly and physical properties of systems and materials currently employed, enabling readers to fully understand the materials and scope for applications.

Production, Places and Environment - Ray Hudson - Bog - Taylor & Francis Ltd - Plusbog.dk

Production, Places and Environment - Ray Hudson - Bog - Taylor & Francis Ltd - Plusbog.dk

Drawing upon 25 years of original research, Production, Places and Environment provides a unique combination of rich, varied and theoretically informed case studies, along with more general analyses of processes and changing theoretical and methodological perspectives in economic geography that are informed by original empirical research.Through a huge range of his own groundbreaking case material the author explores such essential factors as space, production, social and political concerns, and environmental issues, being careful to ground the more complex theory in the more general tendencies in economic geography and the social sciences.

Co-produced Economies - Ray Hudson - Bog - Taylor & Francis Ltd - Plusbog.dk

Co-produced Economies - Ray Hudson - Bog - Taylor & Francis Ltd - Plusbog.dk

In common with most other advanced capitalist economies of the Global North, the UK has experienced a decline in the manufacturing industry and an increase in the service sector in recent decades. At the same time, there has been a substantial manufacturing growth in a number of countries in the Global South, especially China and India. Why have these changes occurred? What have been their economic and ecological consequences? How can we best understand the way the contemporary economy functions? This book explores the answers to these questions, proposing that the contemporary capitalist economy is best understood as a complex socio-spatial system of co-production involving relations between people, things and non-human entities. It is argued that these people typically have conflicting and competitive interests yet can come together to resolve their differences or find ways of regulating their conflicting interests. National states continue to have a critical role in establishing these systems of regulation. At the same time, many companies draw on the knowledge of their customers while others enrol animals, insects and plants as co-producers. As a result, the improbable processes of commodity production and capital accumulation continue more or less routinely; with problems and occasional crises overcome in a variety of ways. Co-produced Economies will be of interest to students of economic geography, political economy and economic development, and more generally to social scientists interested in issues of the causes and consequences of economic change. It will also be of relevance to policy makers seeking to develop economic policies in the increasingly volatile global economy and in the context of growing environmental concerns.
