Book Description
Cette étude est basée sur un modèle de deux grains en contact ayant subi un début de dissolution, et modélisés par deux sphères tronquées pour l'étude du problème mécanique de transfert en solution. Une approche analytique permet de comprendre que la singularité de la contrainte au point de jonction entre la zone de contact et le pore a pour origine la discontinuité du chargement, discontinuité qui se retrouve dans les calculs par éléments finis. La méthode numérique permet de constaterr que l'appoximation consistant à négliger l'énergie libre d'Helmholtz dans la force thermodynamique est valable pour les différentes tailles des grains étudiés. La distribution de la contrainte intergranulaire est moins parabolique quand le grain s'aplatit. La loi de fluage permet de constater que plus la taille du grain diminue, plus le processus de diffusion est rapide : la dissolution est dans ce cas le mécanisme qui gouverne le transfert en solution. L'analyse de stabilité 3D montre que l'instabilité est une onde dont le front est perpendiculaire à la direction de la contrainte effective de compression maximale.

Book Description
Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Pages : 292
Book Description
This book represents a first considered attempt to study the factors that conditioned industrial chemistry for war in 1914-18. Taking a comparative perspective, it reflects on the experience of France, Germany, Austria, Russia, Britain, Italy and Russia, and points to significant similarities and differences. It looks at changing patterns in the organisation of industry, and at the emerging symbiosis between science, industry and the military.
Psychoanalysis of Technoscience
Author: Hub Zwart Publisher: LIT Verlag Münster
ISBN: 3643910509
Category : Philosophy
Languages : en
Pages : 206
Book Description
This book presents a psychoanalysis of technoscience. Basic concepts and methods developed by Freud, Jung, Bachelard and Lacan are applied to case histories (palaeoanthropology, classical conditioning, virology). Rather than by disinterested curiosity, technoscience is driven by desire, resistance and the will to control. Moreover, psychoanalysis focusses on primal scenes (Dubois' quest for the missing link, Pavlov's discovery of the conditioned reflex) and opts for triangulation: comparing technoscience to "different scenes" provided by novels, so that Dubois's work is compared to missing link novels by Verne and London and Pavlov's experiments with Skinner's Walden Two, while virology is studied through the lens of viral fiction.
The Technological System

Pages : 379
Book Description
Some 20 years after writing The Technological Society, Jacques Ellul realized how the totalistic dimensions of our modern technological milieu required an additional treatment of the topic. Writing amidst the rise of books in the 1970s on pollution, over-population, and environmental degradation, Ellul found it necessary, once again, to write about the global presence of technology and its far-reaching effects. The Technological System represents a new stage in Ellul’s research. Previously he studied technological society as such; in this book he approaches the topic from a systems perspective wherein he identifies the characteristics of technological phenomena and technological progress in light of system theory. This leads to an entirely new approach to what constitutes the most important event of our society which has decisive bearing on the future of our world. Ellul’s analysis touches on all aspects of modern life, not just those of a scientific or technological order. In the end, readers are compelled to formulate their own opinions and make their own decisions regarding the way a technique-based value system affects every level of human life.
