La mort cellulaire active (apoptose) est un phénomène ubiquitaire dans les organismes multicellulaires. L'apoptose joue un rôle essentiel dans la genèse d'un cancer et dans la réponse au traitement oncologique. Les radiations ionisantes sont capables d'induire une mort mitotique et une mort apoptotique. Nous définissons les caractéristiques radiobiologiques de chaque type de mort cellulaire et situons l'importance de l'apoptose pour la réponse tumorale aux radiations ionisantes. La modulation de ce «suicide cellulaire» devrait permettre une amélioration de l'index thérapeutique mais ceci implique une connaissance approfondie des mécanismes qui règlent l'apoptose [less ▲]

A talerole analysis of prominent Newfoundland ballad and narrative song records on the theme of death highlighting coherent meaning throughout the different layers of the local song tradition, i.e. an exclusive and constant preoccupation with tragic, sudden, premature and violent death as an inspiration to courage and responsibility rather than despair or resignation.

A l’heure actuelle, plus personne n’ignore que nos populations d’abeilles domestiques subissent de lourdes pertes, chez nous comme dans de nombreux autres pays. Les médias ont axés leur communication sur des messages très simples. On en retient surtout que les pesticides tuent nos abeilles. La conclusion au problème est dès lors évidente : il faut interdire les pesticides. Mais cette problématique est-elle si simple ? Ce message est-il le même que celui communiqué par les scientifiques ? Cette conférence permettra de faire le point sur les pertes en colonies d’abeilles domestiques. On s’intéressera plus particulièrement aux pertes de ces dernières années en Belgique, cartes et chiffres à l’appui. On y verra aussi comment chacun, qu’il soit citoyen, apiculteur, agriculteur,… peut aider à enrayer cette mortalité effrayante. [less ▲]

Contact mechanics is present in a wide range of mechanical engineering applications, and numerous works have been dedicated to the numerical solution of contact problems. Mathematically, the frictional contact problem can be seen as defined by a variational inequality. The solution corresponds to the minimum of the total energy of the system, subjected to inequalities constraints associated to the normal and tangential components of the traction and distance vectors, respectively. Nonlinear contact mechanics can be related to nonlinear optimization problems formulated by using the method of Lagrange multipliers, resulting in a saddle point system to be solved at each iteration. The method of Lagrange multipliers is very popular in contact mechanics because it overcomes the ill-conditioning inconvenience of the penalty methods. However, the size of the global matrix increases due to the additional unknowns (the Lagrange multipliers) and zero entries appear on the main diagonal of the stiffness matrix. These drawbacks can be avoided by using an augmented Lagrangian method, which consists in a combination of both the penalty and the Lagrange multipliers techniques. In this work, a mixed penalty-duality formulation based on an augmented Lagrangian approach for treating the contact and the friction inequality constraints is presented. The augmented Lagrangian approach allows to regularize the non differentiable contact terms, giving a C1 differentiable saddle-point function. The relative displacement of the contacting bodies is described in the framework of the Finite Element Method (FEM) using the mortar method, which gives a smooth representation of the contact forces across the bodies interface.

This work presents a mixed penalty-duality formulation from an augmented Lagrangian approach for treating the contact inequality constraints. The augmented Lagrangian approach allows to regularize the non differentiable contact terms and gives a C1 differentiable saddle-point functional. The relative displacement of two contacting bodies is described in the framework of the Finite Element Method (FEM) using the mortar method, which gives a smooth representation of the contact forces across the bodies interface. To study the robustness and performance of the proposed algorithm, validation numerical examples with finite deformations and large slip motion are presented. [less ▲]

It is not unusual nowadays to hear of people telling us that individuals who had been close to them have helped them after death. These people may have told them what to do when they were faced with difficulties, comforted them, sent them messages of reassurance or even have given them advice. We find this kind of phenomenon in a remarkable number of cultures throughout the world. In this way then it is possible for the dead to continue to help and to engage in fruitful post mortem careers which enrich the lives of living people who may have been close to them and in some cases of strangers who can become the channels for this unexpected help. In this way vocations may be created, whether these be those of the departed or those who benefit from the received guidance acting either as experts or merely as helpers. These post mortem destinies do not simply follow from the realisation of such a vocation. All sorts of careers are open to the dead, whether these result from their own free will or not. They are called upon to participate in exchanges of services or of goods; they may be asked to reorganise solidarities. Sometimes the dead may even be expected to participate in political projects.
