Regards croisés sur les expériences étudiantes. L'enquête conditions de vie 2016
2019
International audience; La création de l'Observatoire national de la vie étudiante en 1989 et la succession des enquêtes depuis 1994 ont apporté une contribution significative à la réflexion en analysant différentes dimensions de la condition étudiante, des modes de vie aux modes d'études. Cet ouvrage souligne la diversité de ces expériences étudiantes, scolaires mais également extrascolaires, peut-être du fait d'une porosité de plus en plus grande entre conditions d'études et conditions de vie.Les différentes analyses présentées dans cet ouvrage soulignent la nécessité de convertir la diversité d'expériences en éléments de réussite individuelle et collective. Comme le suggèrent de nombreux…
A music educational daily program to develop cognitive abilities among pre-school children: a way to prevent academic failure?
2011
The idea that "music makes you smarter" and promotes verbal skills (Ho et al., 2003; Forgeard and al. 2000), spatiotemporal capacities (Rauscher and Zupan 2000) or even the QI (Schellenberg 2006) has received attention from general public and researchers. In this study we examined the effects of music training on pre-school and school performance of kindergarten children, in particular the early writing skills. One main question is investigated: what are the benefits of a specific music program for the cognitive abilities development on preschooler children (age 5)? Is it a way to prevent academic failure? We test this hypothesis with a large sample of 487 French preschoolers split up into …
Does a musical program improve the development of cognitive abilities on kindergarten students: a French experience?
2011
The idea that "music makes you smarter" and promotes both cognitive skills as verbal skills (Ho et al., 2003; Forgeard and al. 2000), spatiotemporal capacities (Rauscher and Zupan 2000), school performances (Wetter et al. 2009) or even boost the IQ (Schellenberg, 2004, 2006) has received attention from researchers and general public. In this study we examined the effects of music practice on pre-school and school performance of kindergarten children, in particular concerning early writing skills. Here, one main question is investigated: what are the benefits of a specific music program in the curriculum for the cognitive abilities development on preschooler children (age 5)?
L’écriture et le graphisme à l’ère de la linguistique psychologique
2016
This study deals with the conception of “writing” within the German humanities during the « psychological turn » of the last half of the XIXth - the beginning of the XXth centuries. The focal point is “graphism” and “writing” understood as “expressive movements” (Ausdrucksbewegungen), this notion being bound to the concept of “verbal gesture” within the trend of “psychological linguistics” (1850-1930). Inspired initially by the morphological and physiognomonic tradition (J. Lavater, J. W. Goethe, J. Engel, C. Carus, Th. Piderit), this conception considers language as a particular kind of “expressive movements”. This vision comes back to the German psychology of consciousness elaborated by J…
Utilisation of natural carotenoids from Momordica cochinchinensis (gac) as health compounds : extraction and bioactvity depending on the origin and o…
2014
The aril of Momordica cochinchinensis (gac), plant from the Cucurbitaceae family, is the richest source of lycopene and β-carotene, which are a strong antioxidant and a pro-vitamin A, respectively, interesting for health-complements. First, a process of soft extraction-fractionation was developed for extracting effectively the natural carotenoids from gac without loss of their original quality. Then, the lycopene and β-carotene extracted from gac were analyzed and characterized. At least 95% of the extracts were composed of the all-trans isomer. They were not degraded during the heat-treatment mimicking formulation processing. Their thermal stereo-mutation was evaluated. Lycopene is more an…

Valorization of natural drug products : from extraction to encapsulation
2020
This thesis was carried out at the Laboratory of Pharmacognosy and the Laboratory of Pharmaceutical technology, at the UFR Sciences de Santé, circonscription Pharmacy, in the University of Burgundy Franche-Comté, to find new natural molecules to encapsulate. First of all, we focused on the natural saponins from plants of the Vietnam biodiversity and the french horticulture, belonging to the three genera Dracaena, Cordyline (Asparagaceae) and Weigela (Caprifoliaceae). The work led to the successful isolation and elucidation of 42 natural saponins using various chromatographic techniques. The structures were determined by ESI mass spectrometry and NMR spectroscopy. Among the 17 pure compounds…
Study of the fuel/clad bonding of pressurized water reactors fuel rods
2017
Durability and integrity of materials used in nuclear power plants is a continuous concern of the nuclear power plant owners and developers. During the fuel irradiation in pressurised water reactors (PWR), the whole fuel-clad assembly is subjected to several irradiation-induced modifications. In particular, the fuel element expansion concomitant to the cladding creeping, leads to the contacting of both materials, allowing the oxidation of the inner side of the clad, locally at first, then tending to affect the overall cladding inner surface. At high burnup, a bonding of the fuel periphery with the metallic cladding can be observed, forming the fuel-clad bonding phenomenon, which conditions …
L'activité documentaire, une perspective ergologique
2008
As testify used vocabulary, contemporary training for a future librarian introduce progressively the question of the work by the way of corporate culture rather than the concrete work, the activity. I suggest to substitute this external approach, that meet necessary resistance in the job, for an intern approach by analyzing in first the notion of activity, then the one of documentary activity, concerning a public or a private service. Because of the originality of this approach, the analysis of the activity require first an inquiry on our cultural heritage, the history of ideas. It shows that the activity respond imperfectly at a logical or conceptual questioning, because the activity is an…
Initial stages of metal oxides thin films growth by MOCVD: physicochemical characterisation of the film/substrate interface
2006
The initial stages of Metalorganic Chemical Vapour Deposition (MOCVD) of TiO2 thin films on Si(100) were studied in situ by surface analyses (XPS, ARXPS, AES). An original experimental set-up was built for this purpose and developed. Information obtained from these in situ experiments was completed by ex situ characterisations (HRTEM, SIMS, GIXRD...).The formation of an interfacial SiOy<2 layer resulting of the interaction of the precursor Ti(OCH(CH3)2)4 with the substrate takes place before the formation of stoichiometric TiO2 and leads to the presence of carbon at the interface. At the deposition temperature, 675 °C, silicon diffusion within the TiO2 external layer was also revealed. Conc…
