Some example are presented that show how it is possible to derive from experimental tests made on protected steel sections subjected to fire an apparent thermal conductivity of the insulatin product. The method presented is widely used in Belgium and has been adopted in European standards as one of four possible methods for characterizing insulating products. [less ▲]

The simplest conceivable event that can occur at the gene level can result in the development of efficacious resistance tot antibiotics. The bacterial world behaves as an enormous organism whose cells can exchange their genes very easily. Accordingly, oppotunities for the exhcange of genetic material in nature are probably unlimited. This knowledge cannot be ignored. It leads to the important conclusion that the antibiotics are societal drugs. A resistance gene which has appeared somewhere in the world can travel far and fast.

La résistance de Liège en août 14 et la reconnaissance française : histoire, mythe et mémoire

Il n’est pas exagéré de dire que la décision belge de refuser l’ultimatum allemand du 2 août et la résistance consécutive de la position de Liège furent pour la France une « divine surprise ». Les rapports de l’ambassade française à Bruxelles au cours des mois et même des années précédentes n’avaient en effet guère préparé le Quai d’Orsay au respect par le Gouvernement belge d’une stricte neutralité en cas de conflit. L’impact dans l’opinion publique française fut considérable au point que dès le 7 août 1914, la Ville de Liège se voit remettre la plus haute distinction de la République : La Légion d’Honneur. Décoration méritée car résistance il y a bien eu… Néanmoins, autour de cet événement qui aurait pu comme beaucoup d’autres histoires militaires tomber après quelques années dans les oubliettes de l’Histoire, sont venues se greffer rapidement de nombreuses implications historiographiques, politiques et culturelles. Sur le plan historiographique, il fut de bon ton de magnifier cette résistance à l’excès jusqu’à déclarer que la résistance de Liège avait permis à l’armée française de gagner du temps pour réaliser la manœuvre salvatrice de la Marne : la Ville de Liège connue pour sa francophilie séculaire avait donc permis à elle seule de sauver la République d’un désastre militaire ! Cette version de l’histoire bataille fut enseignée à des générations d’écoliers et jusqu’à l’Ecole de guerre à Bruxelles. Sur le plan politique, les cérémonies de commémoration magnifiant la résistance liégeoise constituent des occasions récurrentes de rapprochement franco-belge saluées d’ailleurs par les militants wallons et francophiles.

Objective To identify any reason for healthcare professionals to resist to provide palliative care and to understand the main interactions between these factors, in order to develop a further work project which could modify them. Definition of resistance The passivity or the unconscious refusal, to reproduce behaviours and/or acts corresponding to the basic principles of the palliative approach when facing palliative patients. Target group Healthcare professionals, i.e all professionals who take care of patients suffering from an advanced or incurable disease. These are doctors, nurses, nursing auxiliaries, and also physiotherapists, psychologists, home carers, etc. Family members of the patient or volunteers were excluded from the target group. Method The causal analysis consists in building a causality tree of a specific problem within a team. The presentation under the form of a tree allows the reading of the identified factors, from the closest to the most distant. The causal analysis is a time-consuming method, but it will form the basis of further work of our team. Result The obtained model is an orderly repertory of the factors which contribute to the cause of the problem. Conclusion The members of the analysis unit have shared their knowledge to create a tool. This tool will be used to determine actions in order to reduce directly or indirectly the resistance to provide palliative care. [less ▲]

Some plant growth promoting rhizobacteria are able to stimulate inducible defense mechanisms that render the host plant less susceptible to a subsequent pathogen attack. This phenomenon, called induced systemic resistance (ISR), can occur in several plant species against a wide range of bacterial, viral and fungal pathogens. Despite extensive work, many aspects of the molecular basis underlying this rhizobacteria-mediated ISR remain unclear. In this context, we have studied for several years the ISR-mediated protective effect of a particular strain, Pseudomonas putida BTP1. In this paper, we present the results obtained by using BTP1 for disease reduction against anthracnose caused by Colletotrichum lagenarium on cucumber and grey mold caused by Botrytis cinerea on tomato. As a result of cucumber treatment with BTP1, we observed an enhanced hydroperoxide lyase activity that could restrict pathogen ingress since this enzyme, acting downstream in the so-called oxylipin pathway, forms short chain aldehydes considered as “volatile phytoalexins”. By contrast, this phenomenon is not involved in the protective effect afforded by the strain in tomato. In this case, disease reduction is more seemingly associated with an early accumulation of antifungal compounds stimulated by the bacterium, showing that specific ISR-related metabolic pathways may be activated in different plants by the same microorganism.
