To study the importance of the spatial analysis in the control of soil heterogeneity in experiment on field, three approaches of statistical analysis were applied to a total height of trees measured at 29 years of age in a comparative test of thirty origins of Aleppo pine (Pinus halepensis Mill.), autochtonous and introduced in Tunisia. Analysis without control of heterogeneity (totally random), with a global control of heterogeneity (complete blocks) and with a local control of heterogeneity (nearest neighbour models) were used. For this last approach using to estimate the plot fertility the one of the nearby plots, various combinations of neighbour were tested with one or two coefficients of regression. The obtained results showed that the reduction of the residual mean square by comparison to the analysis without control of heterogeneity is 30 % to the complete blocks analysis and varied between 66 and 79 % for spatial analysis. Significant positive correlations between plots residues and the average of the residues of the nearby plots were observed before adjustment of data. After adjustment of data by the nearest neighbour models, these correlations were registered a reduction from 92 to 95 % according to the used model. Among the six nearest neighbour models studied, the model bringing in eight neighbours with two coefficients of regression showed itself the most effective. It also seemed that after adjustment of data by nearest neighbour models, using the structure of blocks does not produce a reduction of the residual mean square. [less ▲]

Le modèle Pegase (Planification Et Gestion de l’ASsainissement des Eaux) est un modèle intégré bassins hydrographiques/rivières qui permet de calculer de façon déterministe et prévisionnelle la qualité des eaux des rivières en fonction des rejets et apports de pollution (relation pression-impact). Développé depuis la fin des années 1980 à l’université de Liège, il permet d'orienter les choix des opérateurs publics et privés en matière de gestion des eaux de surface à l'échelle des petits et grands bassins versants. Dans la cadre de la conduite d'opération sur le bassin Moselle/Sarre que lui ont confiée les directeurs de l'eau du Rhin en janvier 2002, l'Agence de l'eau Rhin-Meuse (qui utilisait depuis plusieurs années le modèle Pegase pour ses besoins propres) a proposé aux CIPMS (Commissions Internationales pour la Protection de la Moselle et de la Sarre) de prendre en charge l'application d’une méthode de calcul des relations pressions-impacts via l’application du modèle PEGASE à l'ensemble du bassin international Moselle/Sarre. Le domaine spatial à traiter comporte plusieurs sous-domaines administratifs, avec des systèmes de coordonnées différents: Lambert belge, Lambert français, Gauss-Krüger luxembourgeois, Gauss-Krüger allemand. Chaque administration concernée transmet ses informations dans son système de coordonnées, le pré-processing PEGASE se chargeant d’effectuer les transformations de coordonnées nécessaires. Ce premier rapport présente les travaux qui ont été réalisés pour construire une première application du modèle Pégase à l’ensemble du bassin de la Moselle, bassin international (France, Allemagne, Grand-duché de Luxembourg, Belgique) [less ▲]

We present the very first analysis of the spectroscopic variability of the three rapidly rotating Oef stars HD 192281 (O5(ef)), HD14442 (O5.5ef) and HD 14434 (O6.5( ef)). Radial velocities of the He II lambda 4541 line reveal no evidence of binarity on time scales of a few days, or from one year to the next, for any of the targets. The He II lambda 4686 double-peaked emission and, to some extent, the H absorption line display significant profile variability in the spectra of all three stars. Data gathered during different observing runs spread over six years reveal a rather stable time scale for HD 192281 and HD14442, whereas the variability pattern changes significantly from one year to the other. The case of HD 14434 is less clear as no obvious time scale emerges from our analysis. In a tentative way to interpret this variability, stellar rotation remains a possible clock for HD 192281 and HD14442. However, currently available models addressing stellar rotation fail to explain some crucial aspects of the observed variability behaviour, which appear to be even more complex in the case of HD 14434.

This work aims to evaluate the potential use of insulin-like growth factor 2 (IGF-2) as the dominant thymic self-antigen precursor of the insulin family in designing a tolerogenic approach to type 1 diabetes (T1D) prevention. This evaluation was primarily based on cytokine profile driven by MHC presentation of insulin and IGF-2-derived antigens to PBMC cultures derived from 16 T1D DQ8(+) adolescents. Insulin B9-23, one dominant P-cell autoantigen, and the homologous sequence B11-25 of IGF-2 display the same affinity and fully compete for binding to DQ8, a MHC-II allele conferring major genetic susceptibility to type 1 diabetes (T1D). However, compared to insulin beta 9-23, presentation of IGF-2 B11-25 elicits a suppressive/regulatory cytokine profile with a higher number of IL-10-secreting cells (P < 0.05), a much higher ratio of IL-10/IFN-gamma (P < 0.01), as well as a lower number of IL-4-secreting cells (P < 0.05). Thus, with regard to T1D prevention, administration of IGF-2-derived self-antigen(s) seems to be an efficient approach that combines both antagonism for binding to a major susceptibility MHC-II allele, as well as downstream promotion of an antigen-driven tolerogenic response.

Stable isotopes of carbon and nitrogen are increasingly used in marine ecosystems, for ecological and environmental studies. Here, we examine some applications of stable isotopes as ecological integrators or tracers in seagrass ecosystem studies. We focus on both the use of natural isotope abundance as food web integrators or environmental tracers and on the use of stable isotopes as experimental tools. As ecosystem integrators, stable isotopes have helped to elucidate the general structure of trophic webs in temperate, Mediterranean and tropical seagrass ecosystems. As environmental tracers, stable isotopes have proven their utility in sewage impact measuring and mapping. However, to make such environmental studies more comprehensible, future works on understanding of basic reasons for variations of N and C stable isotopes in seagrasses should be encouraged. At least, as experimental tracers, stable isotopes allow the study of many aspects of N and C cycles at the scale of a plant or at the scale of the seagrass ecosystem. (C) 2004 Elsevier Ltd.

Polymer modification of carbon nanotubes is accomplished using a grafting-to approach. Radicals formed by the thermolysis of poly(2-vinylpyridine) terminated with a radical-stabilizing nitroxide can react with the surface of nanotubes, resulting in grafting densities up to 12 wt.-%. The modified nanotubes, which are easily dispersed in water, can immobilize metal nanoclusters on their surfaces. [less ▲]

Cet article présente et analyse un dispositif de formation visant l’acquisition de compétences en soins infirmiers. Les objectifs poursuivis sont le développement: - d’une méthode pédagogique active : l’apprentissage par problèmes (APP) ; - de l’approche interdisciplinaire et interculturelle, les mêmes problèmes étant résolus par des étudiants de différentes disciplines et cultures ; - de l’utilisation des nouvelles technologies de l’information et de la communication (NTIC) afin de permettre une collaboration maximale « à distance » entre les différents partenaires du projet. L’analyse du dispositif montre que les objectifs pédagogiques poursuivis par l’APP sont atteints. L’approche pluridisciplinaire et pluriculturelle, pour être optimale, demande une grande coordination entre les partenaires, un équilibre entre les groupes d’étudiants des différents pays et disciplines, une formation et un soutien des tuteurs dans l’utilisation de la plate-forme d’enseignement à distance.

For a karstified limestone area in NW Vietnam, the relationship between the distribution of lineaments and borehole specific capacity is determined, resulting in the conclusion that not only the borehole geomorphological-hydrogeological position but also the lineament distribution influences the specific capacity. No significant spatial well yield patterns are evident in this highly fractured-karstified region. The supposition is that lineaments caused by geotectonic activities affect the local variability in borehole specific capacity. Sixteen pumping tests in conjunction with a comprehensive lineament analysis are used to prove this relationship. The boreholes and lineaments are classified into two groups according to their similarity in geomorphological-hydrogeological features. Lineaments tend to be less detectable in discharge areas (lowland, wide and flat valleys) in contrast to the high density in recharge areas (highland narrow-mountainous ravines). In addition, the presence of a stream network in the former can act as a recharge source to the underlain karstic groundwater system. Consequently, boreholes that are in the discharge areas with a lower density of lineaments often produce high yield. For recharge areas with a high density of lineaments, a good correlation is found between lineament density and borehole specific capacity. [less ▲]

Crohn's disease (CD) is associated with low bone mass due to chronic inflammation and other factors. Receptor activator of NF-kappaB ligand (RANKL), its receptor RANK and its decoy receptor osteoprotegerin (OPG) are potentially involved in this process as they regulate osteoclastogenesis and are influenced by pro-inflammatory cytokines. The aim of this study was to determine the levels of soluble RANKL (sRANKL), RANK and OPG expression both in the serum and in the colon of CD patients. Levels of sRANKL and OPG were assessed in the serum and the supernatants of cultured colonic biopsies in patients with CD and controls by ELISA. RANK expression was explored by immunostaining and immunofluorescence of fixed colonic samples. OPG and sRANKL levels were higher in the serum of CD patients as compared to age- and sex-matched controls. Levels of sRANKL and OPG were significantly enhanced in cultured colonic biopsies from CD, and OPG levels correlated with histological inflammation, and pro- and anti-inflammatory cytokine levels. No significant correlation was found for sRANKL. RANK(+) cells were increased in the colon of CD, particularly in inflamed areas. These cells were positive for CD68 or S100 protein. We conclude that serum and local levels of sRANKL and OPG are increased in CD. Moreover, RANK is expressed in the colonic mucosa by subpopulations of activated macrophages or dendritic cells at higher levels in CD compared to normal colon. [less ▲]

Posidonia oceanica shoots sampled from the healthy meadow in the bay of Revelatta (Corsica, France) were transplanted on metallic grids at 10 m depth. Transplanted shoots have been regularly monitored by the measurement of growth, biomass and C, N and P contents in the leaves and the belowground parts. After six months of experiment, the survival rates varied from 14 to 84 % on the different transplantation sites. Leaf biomass on the transplanted cuttings was lower than biomass in the control shoots but root biomass raised from December 2000 to May 2001 on the transplanted shoots. Transplant growth (8,3 +/- 2,3 mm.d(-1).shoot(-1)) after six months was similar to control growth (8,2 +/- 2,8 mm.d(-1). shoot(-1)). The C, N and P contents in transplants were significatively lower than in control shoots suggesting that transplanted cuttings are unable to meet their nutrient requirements. The modifications of the C, N, P contents in the belowground parts of the transplanted shoots indicate a mobilization of these nutrients in those compartments to produce new roots and restore a normal nutrients absorption.
