Au fur et a mesure que les chercheurs repoussent les limites du savoir sur la nano science, les nanomateriaux occupent une place de plus en plus importante dans les applications de tous les jours. Les nanoparticules d’oxyde de magnesium se demarquent par leur stabilite chimique, thermique, electrique, optique et leur compatibilite avec l’environnement sous certaines conditions. Un exemple d’application des nanoparticules de MgO est leur utilisation dans la decontamination des eaux usees des colorants textiles et la depollution de l’air en enlevant le CO2. Il a ete observe que les nanoparticules de MgO ont une grande affinite a capturer les ions OH- et le CO2. La spectroscopie Raman, quant a elle, est une technique versatile, non destructible (c’est-a-dire qui ne detruit pas l’echantillon) et relativement …

The notion of transparency regularly comes up in discussions about the secondary uses of health data. Few studies, however, examine the impact of the presence or absence of transparency on members of the public. This literature review responds to this gap in the scientific literature. It is the result of a secondary analysis of 124 texts from an exploratory review on transparency, following the PRISMAS-ScR guidelines. The results help to identify negative or positive impacts and associate these with certain communication components relating to secondary uses of health data. They also make it possible to identify the components associated with communication deemed transparent or opaque by stakeholders. Transparency, and more specifically continuity of communication, is strongly associated with increased trust and social acceptability, whereas members of the public generally perceive a lack of transparency negatively. This literature review also deepens our understanding of the potential negative impacts of transparent communication.

The excavation of the surroundings of the cathedral at Tours allowed the study of some 1 000 m2 of a scarcely known sector situated less than 100 m from the late roman walled town. The data from this site gives precise indications about the evolution and the state of preservation of archaeological deposits in this area. The in-depth study of a street and part of a residential quarter has appreciably increased our knowledge of the roman period. This excavation also allows us to broach the subject of the transition of the late roman period and to have a more solid understanding of the early medieval suburbium.

This article is a methodological exemplification of the LMS method (Latent Moderated Structural Equations) available in Mplus. Data collected to study teenagers' motivation (n = 434) in physical education will serve to introduce a methodology to assess the interaction of latent variables in structural equation models. The following article focuses on the general understanding of the reader relative to the application of this method as well as on the presentation and interpretation of results. In closing, the benefits of the LMS method are put forward and new methodological exemplification is proposed.
