La voix est le principal support de la communication humaine. Elle constitue un élément de notre identité en révélant nos émotions, tout en étant un outil de travail essentiel pour l’enseignant. Au quotidien, santé et confort vocal sont indispensables pour permettre à l’enseignant d’exercer dans des conditions optimales et d’assurer l’efficacité en pédagogie. Cette intervention a pour objectif d’aider les (futurs) enseignants à comprendre cet outil professionnel qu'est la voix, afin de mieux le maitriser dans l’action mais aussi de le préserver tout au long de leur carrière.

Introduction: Several methods exist to identify population substructure that is due to shared genetic ancestry or regional proximity. These may be SNP-based or haplotype-based (Price et al. 2006, Lawson et al. 2012). Here, we present a flexible unsupervised clustering approach that is built on the ipPCA machinery (Intarapanich et al. 2009). Methods: Our method supports both numeric and categorical data, and can be applied to panels of SNPs and/or haplotypes, or gene-based integrative summaries (Fouladi et al. 2015). Unlike ipPCA, our method involves an iterative process using binary and ternary splits based on multivariate Gaussian mixture modeling of PCs and Clustering EM (CEM) estimation as in (Lebret et al. 2015). To assess performance, we considered different simulated scenarios of FST=[0.0005,0.006], 5,000-20,000 independent SNPs in HWE, 500-8,000 individuals, and 2-4 populations (Balding and Nichols 1995), with 100 replicates for each scenario. SNPs were treated as categorical or continuous (including ancestry-corrected SNPs). Haplotype-based runs used HapMap 3 data: CHB-JPT (FST=0.007) and CEU-TSI (FST=0.004). Result and Conclusion: In simulated scenarios of extremely subtle structure (FST=[0.0009,0.002]), a population classification accuracy of 92.56% or greater was obtained, which was superior to ipPCA. Promising results to detect fine structure were also obtained in case of the HapMap populations. We believe that the ability of our approach to detect subtle structure, including outlier individuals, will be important in molecular reclassification studies of patients from whom underlying population patterns have been removed.

Estetrol (E4) is a natural estrogen we recently characterized as a Selective Estrogen Receptor Modulator (SERM) with agonistic and antagonistic activities depending on target cells. We have also evidenced the functional importance of mixed estrogenic/anti-estrogenic activities of E4 in normal breast development and cancer. Recent molecular studies, indicating that progesterone receptor (PGR) functions as a molecular rheostat to control ERα chromatin binding and transcriptional activity, have revolutionized our mechanistic insights of steroid receptor activities in malignant breast. E4 is a promising candidate for hormone replacement therapy (HRT) at menopause. However, the impact of the combined use of E4 and progesterone on normal breast physiology and on breast cancer development has not been evaluated yet. To fill this gap, we will evaluate the impact of treatments of E4 and/or progesterone on mammary gland development and breast cancer risk as well as on established breast cancer cells. We will unravel the molecular mechanisms driving the dual estrogenic/anti-estrogenic feature of E4 alone or combined to progesterone by evaluating the putative contribution of the extranuclear ERα, of GPER and by studying the modulation of ER/PGR interactions. This study will be conducted thanks to international collaborations (INSERM Toulouse, Reims, CNRS Rennes, Curie Institute Paris) we established through the EU SEPTIME project we coordinate. Through this project, we will bring new insights to the intriguing dual estrogenic/anti-estrogenic activity of E4. We will bring rational data about the putative safety of HRT combining E4 and progesterone. The development of an animal model assessing the effect of HRT on breast cancer risk in menopaused mice will also provide a useful tool to evaluate the effect of new HRT candidates on breast cancer risk. Moreover, the potential anti-tumor synergism of E4 and progesterone would contribute to the evolution of breast cancer treatment. [less ▲]

Le règlement en basket-ball est très complexe. Il exige beaucoup d’interprétations et une bonne connaissance des nombreuses règles. Leur méconnaissance est considérée comme une origine possible des contestations des décisions arbitrales. Il s’avère donc intéressant de déterminer le niveau de maitrise des règles chez les acteurs du basket-ball. Peu de données existent à ce sujet et, parallèlement, très peu de formations sont organisées pour apprendre le règlement. Cette étude a pour objectif d’interroger les différents acteurs de ce sport par rapport à leurs connaissances du règlement, via un questionnaire pratique et rapide validé par des experts. Les résultats de ce travail montrent l’ignorance et la mauvaise interprétation des règles, surtout chez les sujets n’ayant reçu aucune formation spécifique dans la discipline. Ces résultats sont le point de départ d’autres études sur la problématique évoquée. [less ▲]

In this work, a global process has been developed to produce at a large scale pure TiO2 films deposited on steel in order to get an easy-to-clean surface. This large scale process implies an easy aqueous sol-gel process for the synthesis of the TiO2 sol. This synthesis [1] has been simplified to make easier the extrapolation towards an industrial scale. Results of TEM, photocatalytic properties, film hydrophilicity, and texture obtained with the simplified aqueous sol-gel synthesis (IsoP-TiO2 synthesis) show similar properties than those obtained with the standard aqueous sol-gel synthesis of TiO2 developed previously (HAc-TiO2 synthesis [2]). Only XRD patterns were slightly different with the presence of anatase-brookite phases in IsoP-TiO2 synthesis while anatase phase only was observed in HAc-TiO2 synthesis. Both the aqueous sol-gel synthesis of pure TiO2 and the film deposition on steel by roll-coating have been successfully extrapolated to a larger scale. Indeed, the deposition was done on a pilot line, the steel substrate is 25 cm width, and the band length is 800 m. The coating was deposited at line speed ranging from 30 to 120 m.min-1.The photocatalytic activity and the hydrophilicity of the film were found to be unchanged compared to the films produced at a laboratory scale, thus validating the production of an efficient easy-to-clean material. Even if some problems have still to be solved, this study is a hopeful first step in the development of a large scale process for self-cleaning steel production. [1] S. Mahshid, M. Askari, M.S.

Le droit des relations familiales internationales est au centre d'importantes évolutions qui modifient de manière substantielle le visage de cette discipline. Les relations familiales internationales font tout d'abord l'objet d'une emprise croissante de la part de l'Union européenne. Les questions liées à la dissolution du couple et aux créances alimentaires trouvent depuis peu une réponse exclusive dans des textes européens. Il en va de même pour le volet judiciaire de la protection de l'enfant. L'application des règles européennes ne peut se comprendre sans l'important éclairage fourni par la Cour de justice. A côté de l'intervention européenne, il faut compter avec l'influence grandissante des droits fondamentaux. Des décisions remarquées de la Cour européenne des droits de l'homme ont imprimé leur marque sur des questions aussi diverses que la reconnaissance d'une adoption étrangère ou l'obligation de retour de l'enfant en cas d'enlèvement. Enfin, la politique migratoire exerce également une pression certaine sur les institutions de droit familial : à côté du contentieux fourni relatif aux mariages et cohabitations légales de complaisance, on voit poindre une nouvelle règlementation visant les reconnaissances dites de complaisance. Ces réformes et évolutions, qui s'entrecroisent, nécessitent un éclairage. Cet ouvrage, qui reprend les actes du XIVème colloque de l'association Famille & Droit, organisé en en collaboration avec le Centre de droit privé de l'Université Libre de Bruxelles, a pour objet de dresser un bilan de ces évolutions.

This study formulates an itinerary choice model that is consistent with those used by industry and corrects for price endogeneity using a control function that uses several types of instrumental variables. We estimate our models using database of more than 3 million tickets provided by the Airlines Reporting Corporation. Results based on Continental U.S. markets for May 2013 departures show that models that fail to account for price endogeneity overestimate customers’ value of time and result in biased price estimates and incorrect pricing recommendations. Extensions to advanced discrete choice models show the importance of accounting for inter-alternative substitution for products that share similar departure times. [less ▲]

In this study, a 3-D thermal numerical modelling of laser cladding by powder injection as a repair technology applied to Ti-6Al-4V was developed. In order to implement the movement of the heat source in the model and the addition of material, a C++ programme was developed. Transition refinement elements are used to reduce the number of degrees of freedom. The temperature distribution and its time evolution were computed which allowed the prediction of the heat affected zone and the fusion size of the substrate. Effects of heat source distribution, energy input are investigated. Temperature measurements validate the model. [less ▲]
