V. Braibant,F. Delcroix,A. Oudshoorn,C. Boyerth parental sets of chromosomes within a single nucleus. The diploid state is reasonably stable, and the growth, development, and general behavior of diploids are similar to their haploid parents. However, during normal growth of diploids, cells may spontaneously lose one copy of each chromosome at

S. Beuzit,A. Habbalsomes can now be accessed and analyzed. One of the initial surprises was the remarkably large number of genes that are shared with plants, animals, and fungi that must have been present in their common progenitor over a billion years ago. The genome encodes a total of about 10, 300 proteins includin

Localization of Collapse Mechanisms for Simplified Vehicle Crash Simulationcle crash simulations. It consists of using a global beam finite element model coupling with results of analytical models for the determination of characteristics in the post-collapse stage. The objective of this paper is to verify, in the context of three dimensional multibody modelling, the locali

Aircraft Engine Blades-Casing Contact Studywhen the engine bears a blade-off event. Two approaches are used simultaneously. The former is a numerical one and consists in a fine rotor/stator contact simulation. Various contactimpact algorithms and time integration schemes are tested on elementary cases. The Lagrange multiplier method appears

Design of a Super Conducting Quadripole Prototypedequately prestressed to withstand the magnetic forces without “quenching”. The mechanical model of such a complex structural assembly must take into account the frictional contact between the various component elements in order to prevent against both displacement and warm peak.
