A Natural Seismic Isolating System: The Buried Mangrove Effects
Philippe Gueguen,Mickael Langlais,Pierre Foray,Christophe Rousseau,Julie Maury
Physics , 2011, DOI: 10.1785/0120100129
Abstract: The Belleplaine test site, located in the island of Guadeloupe (French Lesser Antilles) includes a three-accelerometer vertical array, designed for liquefac- tion studies. The seismic response of the soil column at the test site is computed using three methods: the spectral ratio method using the vertical array data, a numerical method using the geotechnical properties of the soil column, and an operative fre- quency domain decomposition (FDD) modal analysis method. The Belleplaine test site is characterized by a mangrove layer overlaid by a stiff sandy deposit. This con- figuration is widely found at the border coast of the Caribbean region, which is exposed to high seismic hazard. We show that the buried mangrove layer plays the role of an isolation system equivalent to those usually employed in earthquake engineering aimed at reducing the seismic shear forces by reducing the internal stress within the structure. In our case, the flexibility of the mangrove layer reduces the distortion and the stress in the sandy upper layer, and consequently reduces the potential of liquefaction of the site.

Abstract: Purulent pericarditis (PP) usually occurs in the compromised host [1]. Predisposing factors have changed over time. Pneumonia was the primary source of infection for the majority of patients (72%) in the pre-antibiotic era, compared with only 22% of patients in the post-antibiotic era [2]. Nowadays, most cases of PP are healthcare associated. Bloodstream infections or underlying non-infectious conditions such as thoracic surgery, chronic kidney disease, immunosuppression, or malignancy (Table 1) are new predisposing factors.Despite medical progress, PP is still associated with high mortality (20 to 30%) attributed to both early and late complications, namely persistent PP and constrictive pericarditis [1,2]. These late complications may be prevented by early pericardiectomy, a surgical procedure known for its potential morbidity. Twenty years ago, intrapericardial fibrinolysis emerged as a promising alternative to surgery. Nevertheless, there is no consensus about its indication.The history, pathophysiology, complications and surgical management of PP are described. In light of the physiological and histological data, we review the rationale of fibrinolysis in PP, the evidence for its efficacy, and all publications on indications, timing, results, and complications.We searched for reported case series of PP managed with fibrinolysis. We reviewed the MEDLINE database since 1951. The following keywords were used: 'purulent pericarditis', 'infectious pericarditis', 'constrictive pericarditis', 'fibrinolysis', 'streptokinase' (SK), 'urokinase' (UK), 'tissue plasminogen activator' (tPA), and 'pericarditis'. We reviewed only English-language literature. We found 134 cases including 94 cases reported in one single study, providing pooled results of 60 tuberculous pericarditis patients and 34 PP patients. As patients with tuberculous pericarditis were excluded, only 74 cases were finally considered. As the specific outcome of the 34 PP cases was not available, our outcome a
Prediction of extubation outcome: a randomised, controlled trial with automatic tube compensation vs. pressure support ventilation

Abstract: In a prospective study, patients who had received mechanical ventilation for more than 24 hours and met defined criteria for a weaning trial, underwent a one-hour spontaneous breathing trial with either ATC (n = 87) or pressure support ventilation (PSV; n = 93). Those tolerating the trial were immediately extubated. The primary outcome measure was the ability to maintain spontaneous, unassisted breathing for more than 48 hours after extubation. In addition, we measured the frequency/tidal volume ratio (f/VT) both with (ATC-assisted) and without ATC (unassisted-f/VT) at the start of the breathing trial as a pretrial predictor of extubation outcome.There were no significant differences in any of the baseline characteristics between the two groups apart from a significantly higher Acute Physiology and Chronic Health Evaluation (APACHE) II score in the ATC group (p = 0.009). In the PSV group, 13 of 93 (14%) patients failed the breathing trial compared with only 6 of 87 (6%) in the ATC group; this observed 8% difference, however, did not reach statistical significance (p = 0.12). The rate of reintubation was not different between the groups (total group = 17.3%; ATC = 18.4% vs. PSV = 12.9%, p = 0.43). The percentage of patients who remained extubated for more than 48 hours was similar in both groups (ATC = 74.7% vs. PSV = 73.1%; p = 0.81). This represented a positive predictive value for PSV of 0.85 and ATC of 0.80 (p = 0.87). Finally, the ATC-assisted f/VT was found to have a significant contribution in predicting successful liberation and extubation compared with the non-significant contribution of the unassisted f/VT (unassisted f/VT, p = 0.19; ATC-assisted f/VT, p = 0.005).This study confirms the usefulness of ATC during the weaning process, being at least as effective as PSV in predicting successful extubation outcome and significantly improving the predictive value of the f/VT.Current Controlled Trials ISRCTN16080446Successful weaning and liberation from mechanical
Généralisation d'un Certificat de Compétences en Langues à l'Université de Bretagne Sud : un projet porté par le Centre de Langues

Abstract: Ce compte rendu de communication a pour objectif de dresser une synthèse des premières expérimentations du Certificat de Compétences en Langues de l’Enseignement Supérieur (CLES) menées au niveau du Centre de Langues de l’Université de Bretagne Sud (UBS). Ces expérimentations avaient pour but de mettre en évidence les besoins matériels et humains nécessaires à une mise en place des CLES 1 et 2, tant en amont que pour la certification elle-même.Il est intéressant de souligner que, d'une manièr...
L’intégration du cinéma hollywoodien en classe de langue : réflexions sur quelques points de convergence disciplinaires Hollywood films in the language class-room : sketching out the objectives common to film studies and English learning

Recherche et Pratiques Pédagogiques en Langues de Spécialité : Cahiers de l'APLIUT , 2012, DOI: 10.4000/apliut.2661
Abstract: à partir d’une expérience d’enseignement de l’anglais menée dans une université de lettres et sciences humaines auprès d’un public composé d’étudiants de Langues pour Spécialistes d’Autres Disciplines (LANSAD) de niveau B2, cet article propose d’utiliser les apports théoriques de la recherche sur l’enseignement d’une discipline en langue étrangère pour faciliter l’apprentissage de l’anglais. Il se fonde sur des exemples de mise en uvre pédagogique tirés de A History of Violence (Cronenberg 2005) et de films noirs hollywoodiens pour tenter de dégager les points de convergence entre l’enseignement des études cinématographiques et l’apprentissage de l’anglais. En effet, les compétences de réception et de production nécessaires à l’acquisition de la langue ressemblent à celles qui sous-tendent l’apprentissage de l’analyse filmique. Ces points de convergence sont la condition pour arriver à une véritable intégration entre les disciplines. Based on an experience of teaching English to non-specialist students conducted at a French university in humanities, this paper uses some of the theoretical principles laid down by researchers in Content-Based Instruction (CBI) to present an approach devised to facilitate language learning through film. It draws on examples from A History of Violence (Cronenberg 2005) and the Hollywood film noir genre to identify the points of convergence between film studies and English learning. The receptive and productive skills that underpin language acquisition are analogous to those which form the usual steps of film analysis. The argument is that these points of convergence are necessary to achieve true integration between the two subjects.
Detectors for New Neutrino Experiments

Physics , 2004,
Abstract: There has been great progress in understanding the neutrino sector in the last few years. One mixing angle has not yet been measured, theta-13. Detectors for the current round of long-baseline neutrino oscillation experiments, for future long-baseline off-axis detectors, and for two detector experiments at nuclear reactors are reviewed.
