A crustal-scale cross-section of the south-western Alps combining geophysical and geological imagery

International audienceA geotransect from the Pelvoux Massif (external French Alps) to the Dora-Maira massif (internal Italian Alps), through the Monviso ophiolitic complex was investigated in the framework of a geological and geophysical imagery program of the continental crust: “Géo-France 3D Alpes”. In this paper we present and discuss a new interpretative crustal-scale cross section of the southwestern Alps by combining various geological and geophysical 2D/3D sources. The Apulian mantle (i.e. the Ivrea body) should be divided in two different rigid pieces separated by the prolongation, in depth, of the Penninic Front. These two mantle indenters drive the decoupling of the European crust. The deep crustal architecture is characterized by the stacking, beneath the high- to ultra high-pressure metamorphic nappes, of crustal slices extracted from the European lithosphere. The proposed structural model allows discussing the significance of the crustal-scale partitioning of the present-day strain pattern as well as the significance of the regional seismicity

A passivity-based controller with charge estimation for coordination of converters in a fuel cell System; experimental results

International audienceThe problem of power management of a fuel cell system involving a hydrogen fuel cell with supercapacitors for applications with high instantaneous dynamic power is addressed in this paper. The design of the controller is based on the interconnection and damping assignment - passivity based control. This control strategy is well adapted but requires the load resistance value in real-time. As, in practical applications the load resistance is an unknown physical variable, a load resistance estimation is added in order to manage accurately the power flow and the fuel cell current dynamic. Experimental results are presented demonstrating that this alternative approach is viable

Assessment of a Standardized Pre-Operative Telephone Checklist Designed to Avoid Late Cancellation of Ambulatory Surgery: The AMBUPROG Multicenter Randomized Controlled Trial.

OBJECTIVES:To assess the impact of a standardized pre-operative telephone checklist on the rate of late cancellations of ambulatory surgery (AMBUPROG trial). DESIGN:Multicenter, two-arm, parallel-group, open-label randomized controlled trial. SETTING:11 university hospital ambulatory surgery units in Paris, France. PARTICIPANTS:Patients scheduled for ambulatory surgery and able to be reached by telephone. INTERVENTION:A 7-item checklist designed to prevent late cancellation, available in five languages and two versions (for children and adults), was administered between 7 and 3 days before the planned date of surgery, by an automated phone system or a research assistant. The control group received standard management alone. MAIN OUTCOME MEASURES:Rate of cancellation on the day of surgery or the day before. RESULTS:The study population comprised 3900 patients enrolled between November 2012 and September 2013: 1950 patients were randomized to the checklist arm and 1950 patients to the control arm. The checklist was administered to 68.8% of patients in the intervention arm, 1002 by the automated phone system and 340 by a research assistant. The rate of late cancellation did not differ significantly between the checklist and control arms (109 (5.6%) vs. 113 (5.8%), adjusted odds ratio [95% confidence interval] = 0.91 [0.65-1.29], (p = 0.57)). Checklist administration revealed that 355 patients (28.0%) had not undergone tests ordered by the surgeon or anesthetist, and that 254 patients (20.0%) still had questions concerning the fasting state. CONCLUSIONS:A standardized pre-operative telephone checklist did not avoid late cancellations of ambulatory surgery but enabled us to identify several frequent causes.
