This paper is concerned with two problems related to deep underground storage of nuclear waste. On one hand, a small-scale laboratory experiment has allowed to heat and wet a confined swelling clay. A thermo-hydro-mechanical modelling is proposed and discussed. On the other hand, the extent of the damaged zone produced during tunnelling in clay is discussed based on an hydromechanical modelling showing evidences of strain localisation, i.e. a fracture initiation.

A number of geomaterials constitutive models have been proposed for the coupling of the mechanical behaviour with i) multi-phase fluid flow and suction level, ii) the thermal field changes and iii) more recently the chemical concentration evolution. Most of these models follow a common framework that will be first emphasised and then particularised for the 3 considered couplings. [less ▲]

BACKGROUND: HSV-tk/ ganciclovir (GCV) gene therapy has been extensively studied in the setting of brain tumors and largely relies on the bystander effect. Large studies have however failed to demonstrate any significant benefit of this strategy in the treatment of human brain tumors. Since dexamethasone is a frequently used symptomatic treatment for malignant gliomas, its interaction with the bystander effect and the overall efficacy of HSV-TK gene therapy ought to be assessed. METHODS: Stable clones of TK-expressing U87, C6 and LN18 cells were generated and their bystander effect on wild type cells was assessed. The effects of dexamethasone on cell proliferation and sensitivity to ganciclovir were assessed with a thymidine incorporation assay and a MTT test. Gap junction mediated intercellular communication was assessed with microinjections and FACS analysis of calcein transfer. The effect of dexamethasone treatment on the sensitivity of TK-expressing to FAS-dependent apoptosis in the presence or absence of ganciclovir was assessed with an MTT test. Western blot was used to evidence the effect of dexamethasone on the expression of Cx43, CD95, CIAP2 and BclXL. RESULTS: Dexamethasone significantly reduced the bystander effect in TK-expressing C6, LN18 and U87 cells. This inhibition results from a reduction of the gap junction mediated intercellular communication of these cells (GJIC), from an inhibition of their growth and thymidine incorporation and from a modulation of the apoptotic cascade. CONCLUSION: The overall efficacy of HSV-TK gene therapy is adversely affected by dexamethasone co-treatment in vitro. Future HSV-tk/ GCV gene therapy clinical protocols for gliomas should address this interference of corticosteroid treatment. [less ▲]

L'augmentation de la productivité agricole a été généralement accompagnee d'un usage non rationnel des produits agrochimiques et des engrais azotés en particulier. Les excès d'azote nitrifié, ayant échappé à l'absorption par les racines, subissent la lixiviation de leurs ions nitrate en profondeur générant le risque de pollution nitrique des eaux souterraines. Il est admis que l'intensité de ce phénomène est conditionné par la texture du sol, la capacité d'absorption de Ia culture, la hauteur des précipitations et/ou d'irrigation et par la quantité d'azote minéral appliquée et/ou minéralisée i\ partir de la matière organique native du sol ou cclle qui est apportée.

La partie belge du bassin de la Gueule, dans la région des trois frontières, comporte de nombreuses zones d’habitats qui constituent une source de pollution de la rivière. La mise en service de la station d’épuration de Plombières en 1998 a permis d’améliorer la qualité des eaux de la Gueule à la frontière Néerlandaise, mais sans atteindre une qualité meilleure que celle qu’il y avait fin des années 70 avant la mise en place des réseaux d’égouttage. C’est afin d’expliquer ce paradoxe que la qualité de l’eau du bassin versant de la Gueule a été simulée avec le logiciel PEGASE (Planification Et Gestion de l'ASsainissement des Eaux), en corrélation avec le développement du réseau d’assainissement. La petitesse du bassin (205 km2 répartis sur seulement 4 communes) a en effet permis de rassembler et structurer l'ensemble des données historiques relatives à l'urbanisation et aux différents stades de l'extension du réseau d'assainissement du bassin, et de les intégrer dans le modèle PEGASE. Nous décrivons ici la méthodologie employée et présentons quelques résultats caractéristiques. [less ▲]

This article presents the results analyses of the archaeological and faunal assemblages from the Holocene strata at Trou Al'Wesse (Modave, Liège Province, Belgium). Two strata of human occupation are present in this sequence: the Early Neolithic in stratum 4.1 and the Late Mesolithic in stratum 4.2. The archaeological material includes lithics and ceramics. Faunal analysis of sample column K4 was done for paleoecological and taphonomic analysis of strata 4 and 12. [less ▲]
