  • Chemiluminescent examination of abiotic oxidative stress of watercress

    Watercress (Nasturtium officinale) is an aquatic plant that readily bioaccumulates heavy metals that may be found in contaminated aquatic systems. Toxic effects of contaminants on the physiological processes cause changes in oxidase enzymatic activity in watercress, which can be measured using a luminometer. The luminometer uses the reaction produced when peroxidases break down hydrogen ...

  • Why measuring the ambient NO2 without conversion?

    Nitrogen oxides NOx are pollutants that may have particular impact in terms of greenhouse gases, acidifying air etc ... issuance increased significantly since 1950 with the massive development of transport and industries. It therefore becomes necessary to provide measures always safer these pollutant gases, and to know the reliability of results. Currently, 60% of emissions of NO and NO2 are ...

  • Investigation on the spontaneous combustion of refuse-derived fuels

    Refuse-derived fuel (RDF), a high-caloric material, is used by various combustion processes, such as power plants, as alternative fuel. Several explosion accidents, however, possibly initiated by the spontaneous combustion of stored RDF, have been reported in Japan. Therefore the spontaneous combustion of RDF prepared from domestic garbage was investigated using chemiluminescence. RDF samples ...

  • Measurement of temperature gradients through local extinction using Raman scattering spectroscopy

    Measurements of temperature in laminar flames with localised extinction points were made using line imaging of spectrally resolved laser Raman scattering through the extinction process. A fit to the nitrogen scattering spectrum was used to determine temperature with an accuracy of 30 K. Temperature gradients through the extinction process were measured as the flame strength prior to extinction ...
