This anthology of poems is set against the background of World War I - 'The Great War'. It strives to capture the emotions of those involved in The Great War and to describe their different perspectives. The collection covers the early days of the war and the excitement that came with it - 'He Volunteered' is based on this stage of the war. The reality of the situation that soldiers found themselves in is expressed in 'Never in a Billion Tears' and 'Fastest Finger First'. The camaraderie and the friendships that developed during the war are described in 'Since We Were Boys', and the 'disconnect' between the infantry and the general staff is described in 'Futility Rooms'. The views of the general public were an important aspect of the war, and some of these appear in 'What Do I Know?'.
This book is designed to introduce the reader to the field of NMR/MRI at very low magnetic fields, from milli-Tesla to micro-Tesla, the ultra-low field (ULF) regime. The book is focused on applications to imaging the human brain, and hardware methods primarily based upon pre-polarization methods and SQUID-based detection. The goal of the text is to provide insight and tools for the reader to better understand what applications are best served by ULF NMR/MRI approaches. A discussion of the hardware challenges, such as shielding, operation of SQUID sensors in a dynamic field environment, and pulsed magnetic field generation are presented. One goal of the text is to provide the reader a framework of understanding the approaches to estimation and mitigation of low signal-to-noise and long imaging time, which are the main challenges. Special attention is paid to the combination of MEG and ULF MRI, and the benefits and challenges presented by trying to accomplish both with the same hardware. The book discusses the origin of unique relaxation contrast at ULF, and special considerations for image artifacts and how to correct them (i.e. concomitant gradients, ghost artifacts). A general discussion of MRI, with special consideration to the challenges of imaging at ULF and unique opportunities in pulse sequences, is presented. The book also presents an overview of some of the primary applications of ULF NMR/MRI being pursued.
This book provides an invaluable guide to undertaking development fieldwork in both the developing world and in western contexts. It takes you through all the key stages in development research and covers:
Sensitive, engaging and accessible in tone, the text is rich in learning features; from boxed examples to bullet-pointed summaries and questions for reflection. Development Fieldwork is the perfect companion for students engaged in research across development studies, geography, social anthropology or public policy.
Microcontinuum field theories extend classical field theories to microscopic spaces and short time scales. This volume is concerned with the kinematics of microcontinua. It begins with a discussion of strain, stress tensors, balance laws, and constitutive equations, and then discusses applications of the fundamental ideas to the theory of elasticity. The ideas developed here are important in modeling the fluid or elastic properties of porous media, polymers, liquid crystals, slurries, and composite materials.
