Correlating stress and somatic embryogenesis for NBT: myth or reality?
2018
Global warming and growing demography have increased demand for agronomic resources, leading to increasing lack of land suitable for agriculture and provoking several abiotic stresses which, added to biotic ones, result in physiological and metabolic disorders that impact on crop yield when most needed. Reducing this impact is a major scientific and agronomic challenge and biotechnology would be an efficient alternative. However, to reduce risks of somaclonal variation among regenerants it is better to produce them by somatic embryogenesis directly from explants or gametes, or indirectly from callus or cell suspensions. Thus, globular embryos regenerate and develop through to the heart, tor…
Descriptive methods based on citation frequency
2010
International audience; The limitations of intensity scoring when describing the odor characteristics of a complex product have been documented in the literature. Wine is indeed aromatically complex. This presentation aims to present another descriptive approach based merely on the presence/absence of odorant notes in wines. To test the interest of this method, we carried out the sensory description of odor for 12 Burgundy Pinot Noir wines by two independent panels, one with an intensity-based method (conventional descriptive analysis, DA) and the other with a citation frequency-based method. Three criteria were compared: similarity of the sensory maps, control of panel performance and prac…
Economic analysis of prevention : prevention supply, incentives and preferences in french private medical practice
2011
The traditional approach of the economics of prevention is built around a demand-side logic. This provides fruitful insights about consumer behaviour and public policies related to prevention, but it has nothing to say about the supply side of prevention. The present thesis aims at developing the economics of prevention from the supply-side, in particular the production of services by ambulatory physicians, and to study the incentives to prevention and the preferences of these medical care producers. An institutional analysis enables to underline the obstacles limiting the supply of prevention by French doctors, and shows that it is necessary to develop incentives mechanisms to increase thi…

(De)constructing "America": the Case of Emir Kusturica's Arizona Dream (1993)
2010
International audience; By means of an analysis of Kusturica's only film about America, Arizona Dream, this article argues that while the United States offers a vision of a united society founded on diversity, it also represses, altering in the process both society and the landscape. National unity is consequently a dream – a dream the film suggests that has often been dreamed up by un-Americans. Filtered through Kusturica's own perceptions of America – and his position on the Balkan War (1991-2001) – the film seems to suggest sadness at the loss of a multi-ethnic, multi-cultural perspective. Through its representations of geography and ethnic diversity, and its dense network of filmic cita…
Specificity and Sensitivity Characterization of a Gallium Arsenide Resonant Bio-Sensor
2018
International audience; The characterization of the performances of a Gallium Arsenide (GaAs) based biosensor, in terms of sensitivity and specificity, is reported. The design of the sensor consists in a resonant membrane fabricated in GaAs crystal that operates at shear modes of bulk acoustic waves generated by lateral field excitation. The transducer element was fabricated by using typical clean room microfabrication techniques. The backside of the membrane is functionalized by a self-assembled monolayer (SAM) of alkanethiols to immobilize bio-receptors, which will allow the specific capture of the analyte of interest. The theoretical sensitivity of the sensor had been determined by model…
On the measurement and prediction of the sound absorption coefficient of air-cavity backed perforated plates considering the holes interaction effect…
2012
International audience; This paper deals with the measurement and prediction of air cavity backed perforated plates considering the holes interaction effect under relatively low sound excitation. A revised expression for the radiation contribution is proposed to properly account for the holes interaction effect. This expression is integrated in the characteristic impedance expression following Atalla and Sgard [J. Sound Vib. 303, 195-208 (2007)] model. Perforated plate specimens with different centre-to-centre holes distances (pitches) are built and tested using an impedance tube. The particular cases of holes interaction effect with constant low porosity and of holes interaction effect wit…
Sound absorption coefficient of a porous material covered with a low open area perforated plate under high sound excitation
2012
International audience; The sound absorption coefficient of porous materials covered with low open area perforated plate is studied under high sound intensities in the absence of mean flow. The theoretical considerations are based on the equivalent fluid following the Johnson-Champoux-Allard approach and the use of the transfer matrix method. To take into account the high sound levels effects, the air flow resistivity of each layer is modified following the Forchheimer law. Two specimens of perforated plate are built and tested when backed by a polymeric foam and a fibrous material. A specific impedance tube setup is developed for the measurement of the surface acoustic impedance for sound …
