Cette présentation orale avait pour objectif de ressituer le haubanage des arbres dans le cadre général de la gestion des risques et de présenter les résultats de recherches dans ce domaine. L'amortissement des mouvements de branches, notamment, a été étudié avec et sans haubans. Les liens entre contraintes mécaniques et conditions de vent ont également été mesurés. [less ▲]

Context. Recent progress in the seismic interpretation of field β Cep stars has resulted in improvements of the physics in the stellar structure and evolution models of massive stars. Further asteroseismic constraints can be obtained from studying ensembles of stars in a young open cluster, which all have similar age, distance and chemical composition. <BR /> Aims: To improve our comprehension of the β Cep stars, we studied the young open cluster NGC 884 to discover new B-type pulsators, besides the two known β Cep stars, and other variable stars. <BR /> Methods: An extensive multi-site campaign was set up to gather accurate CCD photometry time series in four filters (U, B, V, I) of a field of NGC 884. Fifteen different instruments collected almost 77 500 CCD images in 1286 h. The images were calibrated and reduced to transform the CCD frames into interpretable differential light curves. Various variability indicators and frequency analyses were applied to detect variable stars in the field. Absolute photometry was taken to deduce some general cluster and stellar properties. <BR /> Results: We achieved an accuracy for the brightest stars of 5.7 mmag in V, 6.9 mmag in B, 5.0 mmag in I and 5.3 mmag in U. The noise level in the amplitude spectra is 50 μmag in the V band. Our campaign confirms the previously known pulsators, and we report more than one hundred new multi- and mono-periodic B-, A- and F-type stars. Their interpretation in terms of classical instability domains is not straightforward, pointing to imperfections in theoretical instability computations. In addition, we have discovered six new eclipsing binaries and four candidates as well as other irregular variable stars in the observed field. The photometric data of the variable stars are only available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via <A href="http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/515/A16">http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/515/A16</A> [less ▲]

We present a seismic analysis of the pulsating hot B subdwarf KPD 1943+4058 (KIC 005807616) on the basis of the long-period, gravity-mode pulsations recently uncovered by Kepler. This is the first time that g-mode seismology can be exploited quantitatively for stars on the extreme horizontal branch, all previous successful seismic analyses having been confined so far to short-period, p-mode pulsators. We demonstrate that current models of hot B subdwarfs can explain quite well the observed g-mode periods, while being consistent with independent constraints provided by spectroscopy. We identify the 18 pulsations retained in our analysis as low-degree (l = 1 and 2), intermediate-order (k = −9 through −58) g-modes. The periods (frequencies) are recovered, on the average, at the 0.22% level, which is comparable to the best results obtained for p-mode pulsators. We infer the following structural and core parameters for KPD 1943+4058 : Teff = 28,050 ± 470 K, log g = 5.520 ± 0.029, M∗ = 0.4964 ± 0.0013 M⊙, log (Menv/M∗) = −2.552 ± 0.070, log (1−Mcore/M∗) = −0.366 ± 0.010, and Xcore(C+O) = 0.2612 ± 0.0080. We additionally derive the age of the star since the Zero-Age EHB 18.4 ± 1.0 Myr, the radius R = 0.2026 ± 0.0070 R⊙, the luminosity L = 22.92 ± 3.13 L⊙, the absolute magnitude MV = 4.21 ± 0.11, the reddening index E(B − V ) = 0.094 ± 0.017, and the distance d = 1183 ± 93 pc.

A mechanistic model, PROCULTURE, for assessing in real time the risk of progression of Septoria tritici (teleomorph Mycosphaerella graminicola) on winter wheat (Triticum aestivum L.) was used in Grand-Duchy of Luxemburg over 2003 to 2009 to simulate disease progression in the canopy at four-replicated field experiments located in three villages (Diekirch district: Reuler; Grevenmacher district: Burmerange and Christnach), representative of the different agroclimatological zones of Luxembourg. This model has been developed in order to guide field observations on the different leaf layers and to find the optimum time of fungicide spray in fields. The model provides information which explains disease progression on the upper leaves. The relationship between disease control by fungicides and yield loss varies from site-to-site and from season-to-season. A weekly PROCULTURE recalibration is routinely done using actual disease levels observed on site. On average, no spray of fungicides or only one application is required to control efficiently the septoria leaf blotch disease. The PROCULTURE forecasts have been validated to be correct in about 85% of all cases. The treatment defined with the simulation model over 2003 to 2009 gave an earning grain yield (80%) more than the other treatments tested and as important as the double treatment for Everlange, Christnach and Burmerange. At Reuler, over 2003 to 2009, treatments based on the Septoria risk simulation model were recommended only in 2007. The climatic conditions of this site tend to favour organic farming in this region where the evolution of the foliar disease is very weak. [less ▲]

Cette année académique 2009-2010 a été riche en débats, parfois contradictoires, qui ont alimenté la réflexion de l’équipe pédagogique et des étudiants, notamment en relation avec le contenu du programme de la 1ère maîtrise en atelier d’architecture. Comment définir le rôle de l’architecte dont le travail doit s’inscrire dans le processus d’un projet de ville ? Comment maîtriser les échelles graphiques d’un projet d’architecture quand on doit l’intégrer, non seulement dans un contexte, mais aussi dans une dynamique plus générale ? Comment prendre position en même temps en termes de typologies et de densités urbaines, en termes de formes, en termes de détails constructifs et de choix de matériaux ? C’est autour de ce type de questionnements que notre équipe pédagogique développe sa didactique. [less ▲]

This paper presents the adaptation of the LARSP (Language Assessment, Remediation and Screening Procedure) (Crystal et al., 1976) from English into French based on the analysis of a corpus of French speaking children ranging between the ages of 18 months and 5 years. Included is a description of particularities of French morphosyntax and the ensuing adaptations that are reflected on the new French LARSP (F-LARSP) chart. The LARSP is a linguistic profile commonly used by researchers and clinicians to carry out “comprehensive and consistent linguistic analysis” (Ball, 1999); more specifically a detailed analysis of the grammar and morphology of children’s spontaneous language samples. The profile was developed in a manner that allows the user to clearly see the child’s grammatical strengths and weaknesses in relation to their chronological age. This is made possible by the notion that the order in which syntactic structures are acquired is relatively stable, at least until the approximate age of 5. Correlation of a child’s morphosyntactic production to their age provides the therapist with vital information regarding an array of areas including the possible diagnosis of language impairment, remediation planning, and measuring treatment efficacy carried out since the last profiling session. The tool is therefore useful for professionals working with children who are suspected of or who have been diagnosed with having forms of language difficulties such as Specific Language Impairment (SLI) where morphology and syntax are commonly affected. The utility of the LARSP, originally designed for Anglophone use, has led to its adaptation to several other languages. Those which have been published for an international audience include Welsh (1988), Dutch (1987), Irish (1990) and Persian (1998). [less ▲]

Cet article étudie comment les élèves camerounais détournent les usages prescrits dans le cadre d’une innovation. La méthodologie utilisée est basée sur la sociologie des usages et l’entretien. Les résultats obtenus montrent que les élèves disposent des stratégies pour re-former l’intégration scolaire des TIC. Pour donc permettre une innovation scolaire adaptée, ce travail propose une approche qui prend en compte à la fois l’utilité et l’acceptabilité de l’ordinateur. [less ▲]
