La représentation sociale de l'hygiène chez les professionnels de santé : Intérêt du recueil par entretien et de l'analyse discursive des opérateurs …
2009
This study deals with professional representations. The goal is to show the representation of hygiene by health care workers: Nurses (N) and Health Care Aides (HCA). Method follows the BSC (Bases Cognitive Schemes) procedure, explicative interviews substitute to the evaluation task. An analysis of associative words points out that for HCA hygiene is associated with acts linked with corporal hygiene and with two synonymous: no trace, no germ Discussion underlines the interest of this method for professional representations studies and nosocomial infections strength.
Do ventilatory parameters influence outcome in patients with severe acute respiratory infection? Secondary analysis of an international, multicentre1…
2021
Purpose: To investigate the possible association between ventilatory settings on the first day of invasive mechanical ventilation (IMV) and mortality in patients admitted to the intensive care unit (ICU) with severe acute respiratory infection (SARI). Materials and methods: In this pre-planned sub-study of a prospective, multicentre observational study, 441 patients with SARI who received controlled IMV during the ICU stay were included in the analysis. Results: ICU and hospital mortality rates were 23.1 and 28.1%, respectively. In multivariable analysis, tidal volume and respiratory rate on the first day of IMV were not associated with an increased risk of death; however, higher driving pr…
Les dispositifs de prise en charge de la difficulté scolaire à l’école élémentaire : étude de leur fonctionnement et de leurs effets sur la réussite …
2018
With the Jules Ferry laws ensuring free and compulsory schooling, equal chances of succeeding were expected in a meritocratic established school system. Reality proved otherwise: attending school still does not allow all schoolchildren to progress in the same way, as some of them encounter difficulties from the beginning. The struggle against academic failure cannot stop a considerable amount of pupils from finishing school without satisfactorily mastering the basic elements of the programmes. Moreover, recent research works have seemed to prove programmes providing assistance for underachievers to be ineffective.This thesis offers a comparative evaluation of such support systems in element…
Interactions texture-flaveur : mécanismes physico-chimiques ou mécanismes cognitifs ? Application à un gel laitier onctueux
2006
Texture, taste and aroma are key components of the perceived quality of foodstuffs. Many studies showed that modifying one of thèse dimensions could modify the perception of another one. However it is not always clear whether thèse interactions could be attributed to physico-chemical or cognitive mechanisms. The présent work aimed at studying sensory interactions between texture, taste and aroma, in relation with the perception of creaminess, an indicator of food quality. A first step consisted in defining the creaminess concept using sensory and verbal approaches. This study highlighted three groups of consumers: creaminess was associated to texture for the first group, to texture and tast…
The cytoplasmic PASC domain of the sensor kinase DcuS of Escherichia coli : role in signal transduction, dimer formation, and DctA interaction
2013
The cytoplasmic PAS(C) domain of the fumarate responsive sensor kinase DcuS of Escherichia coli links the transmembrane to the kinase domain. PAS(C) is also required for interaction with the transporter DctA serving as a cosensor of DcuS. Earlier studies suggested that PAS(C) functions as a hinge and transmits the signal to the kinase. Reorganizing the PAS(C) dimer interaction and, independently, removal of DctA, converts DcuS to the constitutive ON state (active without fumarate stimulation). ON mutants were categorized with respect to these two biophysical interactions and the functional state of DcuS: type I-ON mutations grossly reorganize the homodimer, and decrease interaction with Dct…

GEOV1: LAI, FAPAR essential climate variables and FCOVER global time series capitalizing over existing products. Part 2: Validation and intercomparis…
2013
International audience; This paper describes the scientific validation of the first version of global biophysical products (i.e., leaf area index, fraction of absorbed photosynthetically active radiation and fraction of vegetation cover), namely GEOV1, developed in the framework of the geoland-2/BioPar core mapping service at 1 km spatial resolution and 10-days temporal frequency. The strategy follows the recommendations of the CEOS/WGCV Land Product Validation for LAI global products validation. Several criteria of performance were evaluated, including continuity, spatial and temporal consistency, dynamic range of retrievals, statistical analysis per biome type, precision and accuracy. The…
OXYDATION D'INTERCONNECTEURS METALLIQUES DE PILE A COMBUSTIBLES DE TYPE SOFC SOUS HYDROGENE ENRICHI EN VAPEUR D'EAU
2008
Les interconnecteurs représentent une pièce maîtresse des piles à combustibles à oxyde solide (Solid Oxide Fuel Cells : SOFCs) car ils sont chargés de collecter et de délivrer le courant produit par la pile. Les matériaux d'interconnecteurs sont à la fois en contact avec l'anode et la cathode et doivent donc être parfaitement stables dans l'air (côté cathodique) et dans l'hydrogène enrichie en vapeur d'eau (côté anodique). Les matériaux métalliques les plus prometteurs sont les chromino-formeurs. Ces alliages sont choisis car, à haute température, ils forment une couche de chromine, Cr2O3, protectrice vis-à-vis des conditions corrosives de fonctionnement de la pile. Cependant, cette couche …
Structure of SNX9 SH3 in complex with a viral ligand reveals the molecular basis of its unique specificity for alanine-containing class I SH3 motifs
2021
Class I SH3 domain-binding motifs generally comply with the consensus sequence [R/K]x0PxxP, the hydrophobic residue 0 being proline or leucine. We have studied the unusual 0 = Ala-specificity of SNX9 SH3 by determining its complex structure with a peptide present in eastern equine encephalitis virus (EEEV) nsP3. The structure revealed the length and composition of the n-Src loop as important factors determining specificity. We also compared the affinities of EEEV nsP3 peptide, its mutants, and cellular ligands to SNX9 SH3. These data suggest that nsP3 has evolved to minimize reduction of conformational entropy upon binding, hence acquiring stronger affinity, enabling takeover of SNX9. The R…
Matières de table. Fantaisies gourmandes de Jacques Fontanille.
2021
Following the figurative trajectory of gustatory sensitivity in the work of Jacques Fontanille, three key moments stand out: (1) the entry through the sensory and the flavors, marked by the autonomy of the figurative dimension in the sensitive deployment of the flavor; (2) the putting to the test of the semiotic exploration in different fields of expression: at the table, through "the setting in plate", around the wine; (3) the figurative consistency of the food form as manifestation of a form of life, with its modalities and its modulations
