Résumé : This project aims at providing planners with a grid which would allow a comparison between Best Management Practices (BMPs) in terms of environmental efficiency, economic cost and potential acceptability by farmers. A comparison between different existing or simulated BMPs (Best Management Practices) has been carried out through a cost/effectiveness assessment along with the study of their acceptability by farmers on seven European watersheds in a multidisciplinary framework which includes eleven research teams. Effectivity has been assessed as the evolution of water quality resulting from BMPs' implementation in experimental watersheds. Particular efforts is being carried out to improve BMPs representation in hydrological models, as they can take various forms from landscape structures modifications to agronomic recommendations. Spatial modelling, at various scales, is used to define critical areas where efforts should be concentrated. For costs, efforts concern the evaluation of both direct and indirect costs induced by BMPs implementation. When studying diffuse pollution, individual contributions and de-pollution costs were not known and had to be assessed. Direct costs are estimated through the definition of contract menus in a Principal/Agent modelling framework, or, depending on the available data, with linearly optimised profit functions. Indirect costs have been considered as being the impact of BMPs on all other branches of the economy and were evaluated by using a general equilibrium model. A cost/effectiveness ratio was calculated for each studied BMP, allowing a comparison of possible alternatives. Unfortunately farmers tend not to apply BMPs as would be desirable. Possible explanations include their poor commitment to environmental improvements and their practice of insufficiently implementing BMPs. Extensive interviews have been carried out to account for the social dimension of farmers' decision making process. In addition, complementary interviews with land managers helped defining practices already implemented and problems that have already been encountered. This work aims at defining new negociative implementation methods which will be evaluated in a demonstration project involving both local land managers and farmers.

Résumé : This paper investigates the computation of the eigenmodes of the Laplacian operator in multi-connected three-dimensional spherical spaces. General mathematical results and analytical solutions for lens and prism spaces are presented. Three complementary numerical methods are developed and compared with our analytic results and previous investigations. The cosmological applications of these results are discussed, focusing on the cosmic microwave background (CMB) anisotropies. In particular, whereas in the Euclidean case too-small universes are excluded by present CMB data, in the spherical case, candidate topologies will always exist even if the total energy density parameter of the universe is very close to unity.

Résumé : Interleukin 6 (IL-6) is endowed with a lectin activity for oligosaccharide ligands possessing the HNK-1 epitope (3-sulfated glucuronic acid) found on some mammalian glycoprotein N-glyeans (Cebo, C., Dambrouck, T., Maes, E., Laden, C., Strecker, G., Michalski, J. C., and Zanetta, J. P. (2001) J. Biol. Chem. 276, 56855691). Using high affinity oligosaccharide ligands, it is demonstrated that this lectin activity is responsible for the early dephosphorylation of tyrosine residues found on specific proteins induced by interleukin 6 in human resting lymphocytes. The gp130 glycoprotein, the signal-transducing molecule of the IL-6 pathway, is itself a molecule possessing the HNK-1 epitope. This indicates that IL-6 is a bi-functional molecule able to extracellularly associate its alpha-receptor with the gp130 surface complex. Computational modeling indicates that the lower energy conformers of the high affinity ligands of IL-6 have a common structure. Docking experiments of these conformers suggest that the carbohydrate recognition domain of IL-6 is localized in the domain previously identified as site 3 of IL-6 (Somers, W., Stahl, M., and Seehra, J. S. (1997) EMBO J. 16, 989-997), already known to be involved in interactions with gp130.

Résumé : The volatile constituents of the supposed defensive secretions of the glandular pouches of the adults of both sexes of the cockroach Therea petiveriana have been shown to contain N-3-methylbutylacetamide (MBA) and N-3-methylbutylpropanamide (MBP), which represented 60% of the volatile fraction. The other 40% included acidic, aromatic, and aldehydic compounds. Behavioral experiments demonstrated that the secretion acts as an alarm pheromone for adults.
