Influence of temperature on the infrared spectrum of the coronene molecule

Laboratory experiments were performed to study the temperature dependence of the absorption spectrum of the coronene molecule (C24H12), believed to be representative of the polycyclic aromatic hydrocarbon (PAH) molecules present in the interstellar medium. The main results is that both line positions and total intensities are almost unchanged when varying the temperature so that the spectrum is mostly temperature independent in the explored range, supporting the modeling of the IR emission originally made by Leger and Puget where room temperature was used in the calculations. In the structure of the band shape, small temperature correlated changes are observed. Qualitative arguments are given to interpret them

Guiry-en-Vexin – Église Saint-Nicolas

Cette intervention de sauvetage a été menée du 16 mai au 16 juin 1998, en préalable aux travaux d’assainissement du croisillon nord du transept. Il s’agissait de fouiller dans l’emprise des tranchées de drainage extérieur. L’opération succède à la fouille menée en 1997, de part et d’autre de la nef, par la même équipe scientifique (BSR 1997, p. 150). Ce secteur est très mal connu archéologiquement ; seules, quelques observations avaient pu être effectuées par Jacques Sirat il y a plus de tren..

Prevention of urinary tract infection in spinal cord-injured patients: safety and efficacy of a weekly oral cyclic antibiotic (WOCA) programme with a 2 year follow-up--an observational prospective study.

POPULATION: Spinal cord injury (SCI) patients with neurogenic bladder have an increased risk for symptomatic urinary tract infection (UTI). Recurrent UTI requires multiple courses of antibiotic therapy, markedly increasing the incidence of multidrug-resistant (MDR) bacteria. METHODS: During an observational prospective study, we determined the safety and efficacy of a weekly oral cyclic antibiotic (WOCA) regimen to prevent UTI in SCI adult patients with neurogenic bladder undergoing clean intermittent catheterization. The WOCA regimen consisted of the alternate administration of an antibiotic once per week over a period of at least 2 years. The antibiotics chosen were efficient for UTI, well tolerated and with low selection pressure. RESULTS: There was a significant decrease in antimicrobial consumption linked to the dramatic decrease in the incidence of UTI. Before intervention, there were 9.4 symptomatic UTIs per patient-year, including 197 episodes of febrile UTI responsible for 45 hospitalizations. Under the WOCA regimen there were 1.8 symptomatic UTIs per patient-year, including 19 episodes of febrile UTI. No severe adverse events and no new cases of colonization with MDR bacteria were reported. CONCLUSIONS: In this prospective, observational pilot study a novel approach to the prevention and treatment of UTI in SCI was investigated. Our study shows the benefit of WOCA in preventing UTI in SCI patients

A case study of capitalisation and valorisation of our technical heritage

International audienceFor the 2008 CIRP Design conference, we have presented a scientific article dealing with a new way of thinking our technical heritage: we would like to preserve it as a digital object. Project deals with a physical mock-up of Nantes city built in 1899 and used for the Universal exposition in France in 1900 in Paris. The heritage object is nowadays in the museum but exposed as a fish inside an aquarium. Thanks to a virtual system coupling a tactile screen with semantic research modules, 3D active screen and light pointer, it will allow the visitor to better understand the mock-up and emphasize important places of Nantes city life. However it does not mean beautiful 3D animation with nice static rendering; indeed, we create virtual mockups which are dynamically operating. We use CAD software and engineering simulation tools. Nowadays the global methodology has been improved: it is named Advanced Industrial Archaeology. In this communication, we will detail a new experimentation done in partnership with a French museum: the Château des Ducs de Bretagne in France. This project deals with a physical mock-up of Nantes city built in 1899 and exposed in 1900 for the World Fair that took place in Paris, France. The heritage object is nowadays in the museum but exposed as “a fish inside an aquarium”. Thanks to a virtual system coupling a tactile screen with semantic research modules, a 3D active screen and a light pointer, it will allow the visitor to better understand the mock-up and emphasize important places of the city. The mock-up represents our industrial heritage with old shipyards of Nantes
