Experimentally validated structural finite element method analysis of a tibial intramedullary nail: Optimal choice of the contact settings.

This article focuses on the static structural analysis of a tibial intramedullary nail, carried out by the finite element method. The investigated subject is concerned with the issue of frictional contacts that, generating a non-linear problem, play an important role in numerical analyses. Experimental tests were also developed on tibial intramedullary nail specimens.

Strain gauge analysis of implant-supported, screw-retained metal frameworks: Comparison between different manufacturing technologies.

Over the past decades, the technological development in the medical field, coupled with the ongoing scientific research, has led to the development and improvement of dental prostheses supported by screw-retained metal frameworks. A key point in the manufacture of the framework is the achievement of a passive fit, intended as the capability of an implant-supported reconstruction to transmit minimum strain to implant components as well as to the surrounding bone, when subject to any load. The fitting of four different kinds of screw-retained metal frameworks was tested in this article.

Museums on paper in Emilia-Romagna from the sixteenth to the nineteenth centuries: from Aldrovandi to Count Sanvitale.

Ever since the Middle Ages, the art of Emilia Romagna (a region of Italy), and more generally of the Po Valley, has been characterised by great attention to aspects of daily life. This particular situation has undoubtedly encouraged the relations and links between the world of art and that of science. And, indeed, in Emila Romagna throughout the modern age a large number of painters worked on commission for naturalists and an equally large number of scientists and 'amateurs' themselves undertook the illustration of nature, or were interested in the problems and techniques of the figurative arts, or collected objects d'art.
