This book is the first to detail the chemical changes that occur in deforming materials subjected to unequal compressions. While thermodynamics provides, at the macroscopic level, an excellent means of understanding and predicting the behavior of materials in equilibrium and non-equilibrium states, much less is understood about nonhydrostatic stress and interdiffusion at the chemical level. Little is known, for example, about the chemistry of a state resulting from a cylinder of deforming material being more strongly compressed along its length than radially, a state of non-equilibrium that remains no matter how ideal the cylinder's condition in other respects. M. Brian Bayly here provides the outline of a comprehensive approach to gaining a simplified and unified understanding of such phenomena. The author's perspective differs from those commonly found in the technical literature in that he emphasizes two little-used equations that allow for a description and clarification of viscous deformation at the chemical level. Written at a level that will be accessible to many non-specialists, this book requires only a fundamental understanding of elementary mathematics, the nonhydrostatic stress state, and chemical potential. Geochemists, petrologists, structural geologists, and materials scientists will find Chemical Change in Deforming Materials interesting and useful.

Brian Bayly has noticed, and points out in the simplest terms, a feature of the human mind that everybody enjoys but no-one else has cottoned onto. When younger, he traveled in empty lands --- he led the only party that has ever penetrated Antarctica's "Forbidden Plateau." In this book he is in the midst of the human crowd but still breaking new ground. Others have noticed separate details but Bayly sees the whole elephant. Readers will learn something about themselves and about what we enjoy, about Yasmin (with freckles) and about Anju who makes bad coffee. The lively writing animates a wholly serious and well-researched account of a source of pleasure that should have been recognized decades ago. The little-noticed effect pervades our lives and seems to reach down to the deepest levels: if life goes beyond seeking material comfort, what else do we hope tomorrow will bring? What motivates us to enrich our minds and be different from chimpanzees? No expertise necessary! Any readers over age fifteen will be able to see how this neglected topic sheds light on their personal lives and on the hopes and behavior of people at large.

How does it feel when someone you love develops dementia? How do you cope with the shock, the stress and the grief? Can you be sure that you and your family will receive the support you need? In Telling Tales About Dementia, thirty carers from different backgrounds and in different circumstances share their experiences of caring for a parent, partner or friend with dementia. They speak from the heart about love and loss: 'I still find it hard to believe that Alzheimer's has happened to us,' writes one contributor, 'as if we were sent the wrong script.' The stories told here vividly reflect the tragedy of dementia, the gravity of loss, and instances of unsatisfactory diagnosis, treatment and care. But they contain hope and optimism too: clear indications that the quality of people's lives can be enhanced by sensitive support services, by improved understanding of the impact of dementia, by recognising the importance of valuing us all as human beings, and by embracing and sustaining the connections between us. This unique collection of personal accounts will be an engaging read for anyone affected by dementia in a personal or professional context, including relatives of people with dementia, social workers, medical practitioners and care staff.
