Theoretical study of microfiber resonator devices exploiting a phase shift

2008

Phase shifts within microfiber resonators can be exploited to demonstrate compact and fast-responding devices. Two examples, a sensor and a bistable device, where the origins of the phase shift are fundamentally different, are investigated. In the sensor the phase change originates from the change of refractive index of the medium surrounding the microfiber ring. This is a linear mechanism which translates into a change of resonance wavelength. Calculations of a silica microfiber ring immersed in an aqueous solution and operating at a wavelength of 1550 nm show that with a fiber 550 nm in diameter the sensitivity approaches a maximal value of about 1137 nm/RIU. In contrast to the sensitivit…

Treated wastewaters discharged from wastewater treatment plants (WWTP) and livestock effluents are the main sources of contamination of aquatic environments and of agricultural soils by human and animal fecal micro-organisms. Contaminated waters, especially bathing waters, may present a sanitary risk for humans if the concentrations of fecal micro-organisms are high, thus indicating the potential presence of pathogenic and/or antibiotic resistant strains. Soils and crops also can be contaminated by these micro-organisms when treated wastewaters are used to irrigate cultivated soils. Consequently, microbiological quality controls are mandatory for bathing waters and treated wastewaters to ma…

Les effets de l'éducation sensorielle sur les préférences et les comportements alimentaires des enfants

2010

National audience; Ce dossier réalisé en partenariat avec le Centre européen des produits de l’enfant traite de la responsabilité éducative des adultes et de l’éducation de l’enfant futur citoyen consommateur.Il consacre une large place à la mise en place des politiques et des pratiques existantes dans plusieurs pays d’Europe et au Canada. Son ambition est de participer aux débats d’idées et de donner des repères sur les enjeux que représentent pour l’avenir de l’humanité, l’éducation et la consommation. Ce dossier est coordonné par Valérie-Inès de La Ville Professeur de Sciences de Gestion, Directrice Centre Européen des Produits de l’Enfant et Christian Gautellier Directeur des publicatio…

Flavour release as a function of time in sugar matrices, in relation to the perception of their sweetness and taste

2002

Although instrumental or sensory analysis of food flavour profiles is often separated from gustatory studies, certain flavours may be classified as sweet, suggesting an interaction between flavour and aroma in sensory perception mechanisms. This paper contains information on the results of studies aimed at establishing dynamics of flavour and sweetness release in the course of their sensory perception during the mastication of sugar confectionery.

Les restos du goût : 12 ateliers-repas au restaurant scolaire

2010

Collaborateurs : Vincent Boggio, C. Wisner-Bourgeois, Pascal Schlich et Lange Christine; Comment rendre les enfants plus ouverts et plus curieux vis-à-vis de leur alimentation ?

Fos mapping of brain activation induced by the mammary pheromone in the newborn rabbit

2010

The female European rabbit, Oryctolagus cuniculus, displays a surprising maternal behaviour. Indeed, she comes into the nest only once per day and for a very brief period (3-4 minutes), almost exclusively to nurse. A pheromonal signal identified as the 2-methylbut-2-enal and named the mammary pheromone (MP) is emitted in milk by all lactating rabbit females. This chemosensory cue induces typical head-searching and oral-seizing movements in newborn rabbits usually involved in the localisation of the nipples. The MP therefore appears as a biological signal important for sucking, survival and growth in pups. To date, only few data are available regarding the neuronal substrate which sustains t…
