Study of the mechanical behaviour of gravel-emulsions using triaxial tests

This paper presents a study of the cyclic behaviour of a gravel emulsion, from an experimental pavement, using repeated load triaxial tests, developed for unbound granular materials. The material has been tested in three conditions: the gravel emulsion at early age and after a period of curing of 14 days at 35°C, and the granular material without bitumen emulsion. The study included monotonic triaxial tests, to determine the resistance to failure, and cyclic tests, to determine the resilient (elastic) behaviour. The results show that qualitatively,the behaviour of the gravel emulsion is similar to that of unbound granular materials,with a strongly non linear (stress dependent) resilient behaviour and a low resistance to rutting. A non linear elastic model is proposed to describe the resilient behaviour of the gravelemulsion. Finally, the laboratory results are compared with moduli measured in situ, using FWD tests

Seroprevalence distribution of Aichi virus among a French population in 2006-2007.

International audienceLittle is known about the epidemiology of Aichi virus, which is a new member of the family Picornaviridae, in the genus Kobuvirus. We report here on seroprevalence in France. Sera were screened using an enzyme-linked immunosorbent assay (ELISA) for immunoglobulin G. Of 972 sera tested, seroprevalence ranged from 25% for the 7-month-to-9-year-old age group to about 85% for the 30-to-39-year-old age group and older age groups. Our ELISA correlated well with the microneutralization technique. This study shows that Aichi virus is quite frequent in France and that seroconversion occurs before the age of 40

Impact of pharmacist interventions on clinical outcome and cost avoidance in a university teaching hospital

International audienceBackground A significant number of clinical pharmacy services have shown to improve in-hospital medication safety and patient outcome. Prescription review and pharmacist interventions are a fundamental part of hospital clinical pharmacy activities. In a context of restricted financial resources, proving the economic and clinical impact of this activity seems necessary. Objective The aim of this study was to assess the clinical impact on patient outcomes and economic benefit of prescription review by pharmacists. Setting 1624-bed tertiary French university teaching hospital. Method Prospective single center study evaluating prescriptions for which a pharmacist intervention was issued over a 6-month period. The clinical impact of every pharmacist intervention was evaluated by a multidisciplinary experts committee. Economic benefit was evaluated from the public health care system spending standpoint. Main outcome measures Number of avoided hospitalization days and associated public health care system cost-avoidance. Results Prescription review and interventions by pharmacists prevented 73 intensive care unit hospitalization days, 74 continuous monitoring unit hospitalization days and 66 days of conventional hospitalization. €252,294.00 in public health expenditure were thus prevented. For every Euro invested in the prescription review activity, €5.09 of public health spending were potentially saved. Conclusion Our study shows that prescription review and clinical pharmacists' interventions had an impact on clinical outcomes which translated into prevented hospitalization days. Prescription optimization through pharmacist interventions allows significant health care cost savings which makes this service highly efficien

Scientific contributions of Pierre Gadal and his lab—A tribute to Pierre Gadal (1938–2019)

This chapter is dedicated to the memory of Pierre Gadal a former Series Editor for Advances in Botanical Research. Its aim is to describe the research that has been done in his laboratory covering essentially the period 1970–2000 and provides first-hand testimony about how it has been done. Besides the scientific output concerning CO2 and nitrogen assimilation and their regulation described in this chapter Pierre Gadal has been very influential in plant science in France through his interactions with the University system but also with CNRS and INRA communities. Through the organization of the doctorate school in University of Paris-Sud he has helped train hundreds of students, and more specifically concerning his own research group, more than 10 of his former students have become CNRS researchers, many with high positions and responsibilities, a similar number INRA researchers and Professors and Assistant Professors in the University system. Fourteen different colleagues have contributed to this chapter, each with his own perception, heart and guts, a further testimony to the exceptional human and scientific qualities of Pierre.Keyword
