L'esprit commence et finit au bout des doigts. 20 ans d'engagement pour l'intelligence de la main, Edition bilingue français-anglais

Depuis 20 ans, à l'initiative de la Fondation Bettencourt Schueller, le Prix Liliane Bettencourt pour l'intelligence de la main® met en lumière les savoir-faire d'exception, la créativité et l'innovation des métiers d'art qui participent de la scène française artistique contemporaine. Ce catalogue d'exposition est un reflet de cet engagement philanthropique. / For the last twenty years, the Liliane Bettencourt Prize pour l'intelligence de la main®, established by the Fondation Bettencourt Schueller, has highlighted the exceptional skills, creativity, and innovation of craftspeople involved in the French contemporary art scene. This exhibition catalog is a reflection of the Fondation's commitment to philanthropic endeavors.

ELEMENTARY NUMBER THEORY IN NINE CHAPTERS

This book is intended to serve as a one-semester introductory course in number theory. Throughout the book a historical perspective has been adopted and emphasis is given to some of the subject's applied aspects; in particular die field of cryptography is highlighted. At the heart of the book arc the major number theoretic accomplishments of Euclid, Fermat, Gauss, Legendre, and Euler, and to fully illustrate the properties of numbers and concepts developed in the text, a wealth of exercises has been included. It is assumed that the reader will have 'pencil in hand' and ready access to a computer. For students new to number theory, whatever their background, this is a stimulating and entertaining introduction to the subject.

Integral Bridges. A fundamental approach to the time-temperature loading problem

Integral bridges have become increasingly popular in the UK over recent years. Problems and costs associated with failed expansion joints in conventional bridges not only make integral bridges a cost-effective option but also means they have longer lifespans that their counterparts. The Highways Agency standards now require that, wherever possible, all new bridges of less than 60 m length should be of integral form. The growing importance of integral bridges has highlighted the need for more information and guidance to assist in improving bridge design. This book presents the results of research commissioned by the Highways Agency into the thermally induced soil/structure interaction created by environmental temperature changes and the associated cyclical displacements imposed on the granular backfill of bridge abutments. It : develops a better theoretical understanding of temperature-induced cyclic displacements ; in particular the strain ratcheting in backfill soil in contact with a 'stiff' structure, identifies the governing soil parameters and examines their influence, develops numerical modelling procedures to predict soil behaviour, identifies and quantifies the controlling features of bridge structures relevant to the interaction problem This book provides essential information for bridge designers to aid their understanding of the cyclical changes in backfill pressures and settlement due to diurnal and annual changes in bridge deck temperature - a crucial factor when designing integral bridges.
