Co-développement d'un modèle d'aide à la décision pour la gestion intégrée de la flore adventice. Méta-modélisation et analyse de sensibilité d'un mo…
2018
The main threat to agricultural crops are weeds with herbicides being the primary cropping management practice. Due to the negative impact of herbicides on health and environment, their use must be reduced. To replace herbicides, numerous cropping practices need to be implemented. This makes weed management more complicated and, together with necessity of scheduling operations at long-term and the multiplicity of cropping system impacts, explains why models are so useful for designing innovative cropping systems. The aim of this thesis was to develop a Decision Support System (DSS) intended for crop advisors to help design cropping systems that are less dependent on herbicides. Our approach…
Nuevos estándares de calidad de linfadenectomía D3 en la escisión completa del mesocolon tras la hemicolectomía derecha
2022
Introducción y objetivo. Los estándares de calidad anatomopatológica de escisión total del mesorrecto y escisión completa de mesocolon se basan en parámetros anatomoquirúrgicos constantes y están claramente definidos. Mediante estos estándares se ha podido relacionar la calidad de la pieza quirúrgica con el aumento de la supervivencia. La técnica quirúrgica de Linfadenectomia D3 (LD3) en la hemicolectomía derecha se basa en la disección e incorporación a la pieza quirúrgica del tejido linfograso del tronco gastrocólico de Henle y del tronco quirúrgico de Gillot. Numerosos estudios destacan la necesidad de establecer estándares de calidad anatomopatológicos de LD3 hasta el momento no descrit…
CoSAC, un projet pour la conception de stratégies durables de gestion des adventices dans un contexte de changement (climat, pratiques agricoles, bio…
2016
The CoSAC project associates partners from research and development in order to (1) quantify and understand, with experiments, the effects of novel agricultural practices on weeds and the functioning of the agroecosystem, (2) design tools that predict the effect of agricultural techniques et pedoclimate on weed flora, (3) use these tools to design sustainable weed management strategies and to evaluate their performances in contexts of changing agricultural practices, climate, biodiversity, (4) facilitate the adoption of these novel strategies by farmers. We will present the first results of the project, e.g. the effect on weeds of cover crops during fallow or associated to a cash crop, the …
Segmenting the spectators of national team sports: the case of a pre-competition match
2015
It has become common for academics and sports marketing professionals to study and explain the heterogeneity and complexity of sports spectators' behaviours and attitudes, with numerous works addressing this topic But these surveys are more about fans of professional sports clubs (soccer, basketball, baseball, hockey, etc) who attend regular season games in their favourite teams' home stadium or arena. To our knowledge, very few studies have been conducted into spectators of national teams. It is these spectators who are of the focus of this paper.
Tellurite-dependent blackening of bacteria emerges from the dark ages
2019
Environmental contextAlthough tellurium is a relatively rare element in the earth’s crust, its concentration in some niches can be naturally high owing to unique geology. Tellurium, as the oxyanion, is toxic to prokaryotes, and although prokaryotes have evolved resistance to tellurium, no universal mechanism exists. We review the interaction of tellurite with prokaryotes with a focus on those unique strains that thrive in environments naturally rich in tellurium. AbstractThe timeline of tellurite prokaryotic biology and biochemistry is now over 50 years long. Its start was in the clinical microbiology arena up to the 1970s. The 1980s saw the cloning of tellurite resistance determinants whil…
Influence of plant traits, soil microbial properties, and abiotic parameters on nitrogen turnover of grassland ecosystems
2016
International audience; Although it is known that multiple interactions among plant functional traits, microbial properties , and abiotic soil parameters influence the nutrient turnover, the relative contribution of each of these groups of variables is poorly understood. We manipulated grassland plant functional composition and soil nitrogen (N) availability in a multisite mesocosm experiment to quantify their relative effects on soil N turnover. Overall, root traits, arbuscular mycorrhizal colonization, denitrification potential, as well as N availability and water availability, best explained the variation in measured ecosystem properties, especially the trade-off between nutrient sequest…
Nucleation and Growth of CaCO3 Mediated by the Egg-White Protein Ovalbumin: A Time-Resolved in situ Study Using Small-Angle Neutron Scattering
2008
Mineralization of calcium carbonate in aqueous solutions starting from its initiation was studied by time-resolved small-angle neutron scattering (SANS). SANS revealed that homogeneous crystallization of CaCO 3 involves an initial formation of thin plate-shaped nuclei which subsequently reassemble to 3-dimensional particles, first of fractal and finally of compact structure. The presence of the egg-white protein ovalbumin leads to a different progression of mineralization through several stages; the first step represents amorphous CaCO 3, whereas the other phases are crystalline. The formation and dissolution of the amorphous phase is accompanied by Ca (2+)-mediated unfolding and cross-link…
Fasciola spp: Mapping of the MF6 epitope and antigenic analysis of the MF6p/HDM family of heme-binding proteins
2017
MF6p/FhHDM-1 is a small cationic heme-binding protein which is recognized by the monoclonal antibody (mAb) MF6, and abundantly present in parenchymal cells and secreted antigens of Fasciola hepatica. Orthologs of this protein (MF6p/HDMs) also exist in other causal agents of important foodborne trematodiasis, such as Clonorchis sinensis, Opisthorchis viverrini and Paragonimus westermani. Considering that MF6p/FhHDM-1 is relevant for heme homeostasis in Fasciola and was reported to have immunomodulatory properties, this protein is expected to be a useful target for vaccination. Thus, in this study we mapped the epitope recognized by mAb MF6 and evaluated its antigenicity in sheep. The sequenc…
Chronospeciation of uranium released in soil during a long-term DU shell weathering experiment.
2021
Corrosion process was investigated of depleted uranium (DU) ammunition fragments buried for three years in aerobic soils continuously irrigated with water. The continuing corrosion process was triggered through formation of soluble uranyl oxyhydrate phases such as metaschoepite and becquerelite, which were identified by micro-Raman and X-ray diffraction spectroscopy. The soil was not amended by phosphates and, therefore, no uranyl phosphates were found as corrosion products on the DU surfaces by X-ray photoelectron spectroscopy. A speciation modelling at high temporal sequence (chronospeciation approach) indicated that the abundant Fe oxyhydroxides in the soil immobilized the U(IV) released…
