Evolution des problèmes malherbologiques à l’adoption du semis direct sous couvert
2019
Le semis direct sous couvert regroupe un ensemble de pratiques appliquées simultanément en vue de répondre à trois principes : réduction totale du travail du sol, couverture optimale des sols et diversification de la succession culturale. Cette approche représente, en France, une stratégie innovante qui semble convaincre de plus en plus d’agriculteurs. En se privant du travail du sol, la gestion des adventices en semis direct sous couvert devient plus complexe, ce qui limite l’adoption généralisée du semis direct sous couvert. Afin d’éclairer les problèmes malherbologiques rencontrés en semis direct sous couvert, un questionnaire en ligne à destination des agriculteurs a été diffusée en Fra…
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
2008
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the ighest-energies, which are correlated with the positions of relatively nearby active galactic nuclei (AGN) [Pierre Auger Collaboration, Science 318 (2007) 938]. The correlation has maximum significance for cosmic rays with energy greater than ~6 x 1019 eV and AGN at a distance less than ~75 Mpc. We have confirmed the anisotropy at a confidence level of more than 99% through a test with parameters specified a priori, using an independent data set. The observed correlation is compatible with the hypothesis that cosmic rays with the highest-energies originate fro…

Effect of composition information on the perception of innovative beverages mixing animal and plant ingredients by consumers
2021
We studied the reaction of consumers and non-consumers of plant-based alternatives towards beverages mixing cow milk with soy juice or oat juice. We focused on the liking of these products and on the perceived nutritional and environmental quality. We compared the results obtained by presenting the products with or without composition information, with two types of composition information (plant-based or mixed) and between consumers and non-consumers of plant-based alternatives. We found that the plant-based composition information increased the appreciation of products containing oat. Both composition information had a similar impact on the perceived nutritional quality. The mixed composit…

Perception of a blending odor mixture: an fMRI study in humans
2012
Supported by grants from the Burgundy Regional council and EU-ERDF, European Dijon-Dresden Laboratory (LEA 549); Odors we perceive from our environment arise from the processing of mixtures of odorants. Some mixtures can lead to configural or elemental perception depending, in part, on experience. However, the neural bases of such influences are still unknown. In the present study, we examined the neurophysiological correlates of the configural and elemental processing of a binary odor mixture (AB). This AB mixture has previously been shown to blend into one percept, but also to produce a more or less configural perception depending on pre-exposure to either the mixture itself or to the sin…
