This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les alliages cobalt-chrome entrent dans la composition des dispositifs médicaux sur mesure représentés dans notre domaine par les prothèses dentaires. Quelle que soit leur indication, ils doivent répondre à une exigence de base : la biocompatibilité. De plus, ces alliages doivent résister sur le long terme aux sollicitations auxquelles ils seront soumis en bouche. Ces alliages sont traditionnellement mis en forme par coulée. Cette technique exigeante et complexe demande un savoir-faire important et les défauts de coulée sont nombreux. Afin de limiter les problèmes liés à la coulée du métal et de diminuer les coûts, la fabrication additive s'impose de plus en plus dans les laboratoires de prothèse dentaire. L'objectif du travail est d'étudier les alliages cobalt-chrome fabriqués par fusion laser, de les comparer aux alliages obtenus par coulée traditionnelle afin de montrer si la technique de mise en forme a une influence sur la microstructure et les propriétés mécaniques. Le procédé de Fusion Laser Sélective permet de fabriquer des armatures de prothèse fixe ou des châssis de prothèse amovible en réduisant considérablement le nombre d'étape par rapport à la technique de coulée traditionnelle. L'identification et la maîtrise des nombreux paramètres du procédé sont déterminantes. Le choix de ces paramètres (puissance laser, vitesse de balayage, épaisseur de poudre notamment) va influencer la microstructure de ces alliages et donc leur comportement mécanique. La caractérisation métallographique de ces alliages cobalt-chrome fabriqués par fusion laser montre une microstructure dense et homogène qui lui confère d'excellentes propriétés mécaniques. Ces alliages présentent une limite élastique et une résistance maximale supérieures aux alliages coulés. Ces valeurs correspondent aux critères de type 5 de la norme ISO 22674 permettant la mise sur le marché et l'utilisation clinique de ces alliages.

Download or read book Biocompatibility of Co Cr Ni Alloys written by H. Hildebrand and published by Springer. This book was released on 1988 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: For several years now scientific and medical sLaff have recognised the risks of toxicity of certain metals contained in alloys used in Lhe manufacture of biomaterials protheses, implants, and artificial organs. A number or scientific and industrial research centres have focussed their investigations in this direction and international societies and commissions have organised meetings with specialists from complementary disciplines in attendance in attempts to guage the importance of biological risks and to determine the toxicity of certain metals, with the aim of establishing preventive measures and guidelines. In the last century great efforts have been made to reduce unwanted biological effects caused by orthopaedic implants. The problems of pain and infection were overcome and the development of modern technology has resulted in a convincing decrease in corrosion problems and mechanical failure, such that ostosynthesis and endoprosthesis have rapidly progressed beyond the level of tentative investingation.llowever, a number of problems still remain to be solved, such as the influence of the material type on the healing process and its relative speed. The increasing use of cobalt-,chromium-and nickel-containing alloys in surgical and dental implants has raised various questions concerning the biological consequences of chronic internal release of these elements in the human body. A total of 55 delegates representing 16 countries heard presentations of fundamental aspects, local and remote tissue response, immunopathology, clinical aspects, and manufacturing qual ity control issues.

This book was released on 2012-12-06 with total page 845 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on the proceedings of an Advanced Study Institute (ASI) sponsored by the North Atlantic Treaty Organization (NATO) held October 1987 in Corfu, Greece. The Institute received financial support from the National Aeronautics and Space Administration, U.S.A. Armed Forces Radiobiology Research Institute, U.S.A. Department of Energy, U.S.A. Deutsche Forschungs-und Versuchanstalt fur Luft und Raumfahrt e.v., Kaln, Germany The advent of the shuttle era is providing fresh impetus for large space ventures such as communication centers, solar power stations, astronomical observatories, orbiting factories, and space based radar. Such ventures will rely heavily on an extensive and prolonged human presence in space doing in-orbit construction, maintenance, and opera tion. Among the advantages of location in space are the near zero gravity environment, commanding location, and the reception of solar energy and astronomical signals unattenuated by the atmosphere. Central to long-term manned space missions are the problems associated with the effects of exposure to ionizing radiations on humans. Manned space mis sions in the past have encountered relatively benign radiation environ ments because of their very short duration and orbit configuration. However, crew stay time of up to a year has been recently achieved by the Soviet space program; and Mars missions lasting several years are under serious consideration.
Download or read book Animal Sonar written by Paul E. Nachtigall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first meeting on biosonar that I had the opportunity to attend was held in 1978 on the Island of Jersey in the English Channel. That meeting, organized by Professor R.G. Busne1 and Dr. Jim Fish, was my introduction to an exciting and varied group of hard-working and dedicated scientists studying animal echolocation. They are, by nature, a very diverse group. They tend to publish in different journals and rarely interact despite the fact that they all work on echolocation. When they do interact as a group, as they did in Frascati Italy in 1966, in Jersey i~ 1978, and during the meeting reported in this volume, the meetings are intense, interesting, and exciting. This volume is a composition of a series of contributed papers written to foster an interdisciplinary understanding of the echolocation systems of animals. The echolocation pulse production studies in bats and dolphins have recently been concentrated on the ontogeny of infant pulses, other studies, with three-dimensional computer graphics and x-ray computed tomography, have concentrated on finally resolving the old controversy concerning the site of dolphin echolocation click production. Much has been accomplished on the analysis of bat neural structure and function. The intense effort directed toward understanding the structure, connections, and functional properties of parallel auditory pathways and the parallel and hierarchical processing of information by the mustached bat, has lead to dramatic breakthroughs in understanding brain function.
