Étude d'un nouvel outil didactique pour l'apprentissage de la vascularisation du genou en première année de médecine

But : L'objectif de ce projet est de fournir un outil didactique pour l'apprentissage de la vascularisation du genou en première année de médecine. Méthode : Une angiographie est effectuée sur les membres inférieurs d'un cadavre. Des colorants rouges et bleus sont injectés respectivement dans les artères et les veines des genoux. Par la suite, une dissection du genou gauche est accomplie et six coupes transverses du genou droit sont mises en relation avec les images CT correspondantes. Une reconstruction tridimensionnelle de l'angiographie est enfin réalisée. Résultats : Les préparations citées ci-dessus sont présentées aux étudiants lors de séances de travaux pratiques sous forme d'un cours de 30 minutes environ. Conclusion : Il est possible d'améliorer l'enseignement de l'anatomie en faisant varier les angles d'approche d'une même région anatomique. Cette pratique est très appréciée des étudiants. En effet, ceux-ci montrent une grande motivation lors de ces séances de travaux pratiques, ce qui renforce bien évidemment l'apprentissage

Analysis and trade-off studies of large lightweight mirror structures

A candidate mirror, hexagonally lightweighted, is analyzed under various loadings using as complete a procedure as possible. Successive simplifications are introduced and compared to an original analysis. A model which is a reasonable compromise between accuracy and cost is found and is used for making trade-off studies of the various structural parameters of the lightweighted mirror

Content & Watkins's account of natural axiomatizations

This paper briefly recounts the importance of the notion of natural axiomatizations for explicating hypothetico-deductivism, empirical significance, theoretical reduction, and organic fertility. Problems for the account of natural axiomatizations developed by John Watkins in Science and Scepticism and the revised account developed by Elie Zahar are demonstrated. It is then shown that Watkins's account can be salvaged from various counter-examples in a principled way by adding the demand that every axiom of a natural axiomatization should be part of the content of the theory being axiomatized. The crucial point here is that content cannot simply be identified with the set of logical consequences of a theory, but must be restricted to a proper subset of the consequence set. It is concluded that the revised Watkins account has certain advantages over the account of natural axiomatizations offered in Gemes (1993)

Imperfect identity

Questions of identity over time are often hard to answer. A long tradition has it that such questions are somehow soft: they have no unique, determinate answer, and disagreements about them are merely verbal. I argue that this claim is not the truism it is taken to be. Depending on how it is understood, it turns out either to be false or to presuppose a highly contentious metaphysical claim

Re-Stabilization of an Unstable Lumbosacral Segment in a Patient with Chronic back Pain: A Case Report.

Background: Spinal instability is poorly understood. This case report describes the re-stabilization of an unstable vertebral motion segment in a patient with chronic low back pain. Case Presentation: A 50-year-old male presented at his local rheumatology service with chronic lumbo-pelvic pain. MRI revealed mid-lumbar disc degeneration with Modic 1 change at L3-4. An epidural steroid injection was given, followed by antibiotic therapy, but with no effect. A quantitative fluoroscopy (QF) assessment revealed instability at L5-S1 with hypomobility at the degenerate mid-lumbar levels. He received manipulation therapy to the mid-lumbar spine, plus activity modification to minimize lumbo-sacral stresses. This gave 70% improvement which was sustained over 5 years. Follow-up QF and MRI revealed reduction in lumbo-sacral instability, but no change in the L3-4-disc signal. Conclusion: This case report is the first to demonstrate restabilisation of an unstable vertebral motion segment
