“…Moreover, we can consider the plasma reactor as a RLC circuit whose impedance varies with temperature so that the system can move to the electrical resonance domain, as shown by Garamoon et al for a similar plasma system [15]. In the resonance domain conditions, these authors have observed that the input power increases quickly and pass through a maximum corresponding to the resonance conditions.…”

International audienceThis paper reports on experimental measurements of the gas temperature in a dielectric barrier discharge reactor powered by a high voltage pulsed signal. It is shown that the thermal behavior of the reactor follows a first order model. However, an unexpected runaway phenomenon was observed at a frequency of 300 Hz. A sudden increase in the power source and consequently in reactor temperature which reaches 170 degrees C is observed. This behavior is discussed in terms of input power variation with temperature, possibly due to a resonance phenomenon

Angoumois grain moth, Sitotroga cerealella (Olivier), is one of the most important pests of such stored products as maize and wheat. Different stages of this pest were treated with ozone as a gas at three concentrations (1, 3, and 5 g/m 3) for six different periods (0.5, 1, 2, 3, 4 and 5 h.) compared with untreated insects. The results indicated that increasing the concentration and exposure time led to increasing the rate of mortality for all tested stages at parental generation. The results showed that also, ozone affected biological aspects of the progeny resulted from treated stages (egg, larvae, pupae and adult) at F 1 generation.

D EGRADATION of hardly degradable textile dyes in wastewater using dielectric barrier discharge (DBD) plasma method becomes a competitive technology for primary decomposition. In the same trend, new complex Dielectric Barrier Discharge Plasma device has been used in this study to evaluate its results in degradation of textile dyes. The six dyes used are from different classes (acid, basic and reactive) and structure to cover all the bases of dye. Different parameters as exposure time, ozone and dye concentration and their effect on% efficiency (η) of color removal of dyes from their solution were investigated. The decolorization kinetics and both chemical oxygen demand (COD), the effect of final product of the degradation process on the aquatic live is expressed using biological oxygen demand (BOD) analysis. The resultant study shows that, the maximum color removal was obtained by treating the dye solution for 90 sec using ozone concentration 20g/m 2 and concentration of dye 0.5g/l for all the dye. Kinetic studies were been also considered and the obtained results were following first-order reaction.
