Identification de gènes liés à la résistance aux herbicides non liée à la cible chez les Ivraies : vers des tests « moléculaires » de diagnostic
2016
Identification of genes linked to non-target-site resistance to herbicides in ryegrass : towards "molecular" diagnosis assays. Setting up molecular diagnosis tools would greatly foster preventing and managing non-target-sitebased resistance to herbicides (NTSR). This is currently hampered by the complexity of NTSR genetic determinism, which is largely based upon differences in the expression of an unknown number of genes between resistant and sensitive plants. Identifying NTSR genes is thus a challenging task. Herein, we report the identification of 19 genes which expression patterns are correlated to NTSR to ALS-inhibiting herbicides in rye-grasses (Lolium sp.). We demonstrate the potentia…

Identification of functional markers of mycorrhiza efficiency in vineyard
2021
Arbuscular mycorrhizal fungi form a mutualistic symbiotic association with more than 80% ofland plants, including vines. Advantages of this mutualistic symbiosis are countless. Rootcolonisation by mycorrhizal fungi is mainly evaluated through staining and microscopicobservation. However those technics do not allow to differentiate different mycorrhizal fungi.In order to overcome those limits other tools, like antibodies, isoenzymes and molecular biologytechnics, can be used. Nevertheless, all of these methods “only” allow detection of the presenceof mycorrhizal fungi, whereas no information is provided on the proper mycorrhizal symbiosisfunctioning, and therefore on the benefits provided to…

Déconstruction et redéfinition du ‘clandestin’ dans Il ladro di merendine et L’altro capo del filo d’Andrea Camilleri
2022
Andrea Camilleri used to say he regretted that his novels were seen by his readers as more entertaining than thought-provoking. For his work carries a militant message and far-left ideas. In his narratives, the author deconstructs traditional schemes and definitions and proposes to read reality through other prisms. Thus, in his two novels Il ladro di merendine and L’altro capo del filo, Camilleri deconstructs and redefines the concept of ‘clandestinity’, both through inventio and through symbolic objects. The boundary shifts: it no longer separates the licit from the illicit but the intimate from the visible.
Acoustic properties of plates with unevenly distributed macro perforations backed by woven meshes
2012
A hybrid model describing the acoustic properties of plates with macro-perforations that can be unevenly distributed on the plate surface and backed by woven or precision woven meshes with microscopic perforations is proposed. The plate perforations may be of circular or rectangular shapes. Since the perforated plate may not necessarily be considered as an equivalent fluid, its surface impedance is calculated by the Maa model [Noise Control Eng. J. 29, 77-84 (1987)], whereas the Johnson-Champoux-Allard model [J. Appl. Phys. 70, 1975-1979 (1991)] is used for the mesh. It is observed that the absorption of the carrying plate seems to depend on the hydraulic diameter of the perforations and no…
Gas sensors arrays (electronic noses) : a study about the speed/accuracy ratio
2000
Abstract New Fingerprint Mass Spectra (FMS) systems claim for a higher precision, a reduced analysis time, and a lower drift, compared with Gas Sensors Arrays ‘Electronic Noses’. We demonstrated in this study that metal oxide gas sensors may have highly improved performances for both accuracy and run time, when used in optimum conditions. The different noise components were quantified referring to popular words (equivalent of ethanol concentration) using the transfer function of the sensor. It was pointed out that sample surrounding greatly affects the noise level, and that the signal-to-noise ratio may be dramatically increased, reducing the distortion generally assessed between sensor and…
