A potential solution to avoid overdose of mixed drugs in the event of Covid-19: Nanomedicine at the heart of the Covid-19 pandemic.
2021
Since 2020, the world is facing the first global pandemic of 21st century. Among all the solutions proposed to treat this new strain of coronavirus, named SARS-CoV-2, the vaccine seems a promising way but the delays are too long to be implemented quickly. In the emergency, a dual therapy has shown its effectiveness but has also provoked a set of debates around the dangerousness of a particular molecule, hydroxychloroquine. In particular, the doses to be delivered, according to the studies, were well beyond the acceptable doses to support the treatment without side effects. We propose here to use all the advantages of nanovectorization to address this question of concentration. Using quantum…
Les prédicteurs en grande section maternelle de la réussite en lecture en fin de première année de l'école primaire : l'impact du nom des lettres
2009
A number of variables predicting the success or failure in learning to read has been presented in the literature. Investigations, however, aiming to evaluate the impact of these factors in multivariate models are rare, particularly in French, and do not take into account participants' individual and social characteristics. In this perspective, a longitudinal study, comprising 199 students, was realised from kindergarten through first grade. The results show that, among all the variables studied, the naming of consonants and vowels in kindergartens is the best predictor of ackowledging both decoding letters and written comprehension at the end of the first grade. A discussion furthers the im…

Les pratiques pédagogiques des enseignants universitaires :
2012
In France, some studies (Boyer & Coridian, 2002; Clanet, 2001) have highlighted the heterogeneity of teaching practices at the university, especially in the first year, but don't analyze accurately the effects of this variety on the students. However, these practices are not without consequences for them (Bireaud 1990; Bellat Duru, 1995; Galinon Menelec, 1996). So it is to this reflection that is dedicated the research presented in this article. Firstly will be presented studies in France and abroad about the description of practices. The second part will focus on the effects induced by them on students. Finally, we will present an innovative viewpoint of research, on the relationship betwe…
Le numérique à l'école primaire. Analyse des effets conjoints sur les élèves et les enseignants
2020
International audience; Les technologies numériques sont investies en France depuis plusieurs années par les pouvoirs politiques comme un instrument de lutte contre l'échec scolaire. L'hypothèse est parfois faite que les technologies de l'information et de la communication en éducation (TICE) améliorent sensiblement la qualité de l'éducation en modifiant et facilitant les conditions d'apprentissage des élèves. Cependant, les travaux de recherche montrent des effets relativement ambigus de l'utilisation des nouvelles technologies sur les acquis des élèves.
Pédagogie muséale et enseignement du volcanisme à la Réunion
2003
Research into pedagogy in museums underlines the double tranposition of the theory principles of the science media and of psycho-pedagogy. At stake is understanding why and how pupils can build their scientific learning in a museum environment. This present contribution will propose a reflection on this issue based on the example of the teaching of volcanism on Réunion Island. The analysis of interviews conducted with teachers in first schools and secondary schools shows to what extent the pupils benefit from a significant pedagogical impact in the framework of their visits to the thematic museum in Piton de la Fournaise. The results show that the teachers, going further than the objectives…

High-performance micellar liquid chromatography determination of sulphonamides in pharmaceuticals after azodye precolumn derivatization
1995
Abstract A chromatographic procedure with precolumn derivatization to form the N-(1-naphthyl)ethylenediamine dihydrochloride azodyes is proposed for the analysis of several sulphonamides (sodium sulphacetamide, sulphadiazine, sulphaguanidine, sulphamerazine, sulphamethizole, sulphamethoxazole, sulphanilamide and sulphathiazole) in pharmaceutical preparations (tablets, pills, capsules, suspensions and drops). The separation is performed with a 0.05 M sodium dodecyl sulphate/2.4% pentanol eluent at pH 7. The precolumn derivatization improved the resolution in the chromatograms and increased the selectivity in the determination of mixtures of sulphonamides and in preparations where other drugs…
