The problem of hospital effluents falls into the framework of hazardous substances due to the specific substances used and discharged for the most part into urban drainage networks without prior treatment. This in-depth study has led to greater understanding of the effluents discharged by hospitals. The experimental program implemented consisted in carrying(More)
Retention-detention basins are important structures for managing stormwater. However, their long-term operation raises the problem of managing the sediments they accumulate. Potential uses for such sediments have been envisaged, but each sediment must be characterised beforehand to verify its harmlessness. In this paper we address this issue through the(More)
Delayed Ettringite Formation (DEF) consists in an expansion of the affected concrete leading to a decrease of its mechanical properties and thus inducing problems in terms of serviceability and structural integrity. To manage the affected structures, re-assessment tools have to be provided. Such models have to include coupling laws taking into account the(More)
2014 A storage ring free-electron laser oscillator has been operated above threshold at a visible wavelength 03BB ~ 6 500 Å. This laser was obtained with electrons of 166 MeV circulating in the storage ring ACO. The light emitted by the electrons passing through an optical klystron (a modified version of an undulator) is stored in a high-Q optical cavity.(More)
Alkali-Aggregate Reaction (AAR) and Delayed Ettringite Formation (DEF) are both internal swelling processes that can affect concrete. In the field, the two reactions are often observed acting simultaneously. To manage the affected structures, it is necessary to provide numerical tools able to predict the mechanical state of the construction in a reliable(More)
The filling of dry quarries in coastal areas with sediments dredged in seaports represents a potentially interesting method of recycling of these materials. However, this recycling requires the prior carrying out of an Environmental Risk Assessment of the scenario concerned. For this, the question arose as to the type of plants capable of developing on the(More)
Combined Sewer Overflows (CSO) in small peri-urban streams and rivers are potentially toxic for their biocenosis. Improving the management of CSO discharges requires better knowledge of their dynamics and toxicity. In view to characterizing this toxicity, we sampled the different compartments (benthic and hyporheic zone) of a peri-urban stream located near(More)
In the framework of an ecological risk assessment of seaport sediments for terrestrial ecosystems when deposited in quarries, we simulated the "ageing" of sediments exposed to rain. This experiment highlighted an inflection point at the solid/liquid ratio 1/25, after which the extraction of pollutants increases moderately. The raw sediments studied(More)
The aim of the Sustainable Management of Sediments Dredged in Seaports (SEDIGEST) project is to assess the risks of treated port sediments for terrestrial ecosystems when deposited in quarries. We simulated the "ageing" of these sediments up to the "moment" when plants can germinate. Sediments were leached by water percolating through a laboratory column.(More)
