Abstract Electrode erosion through continual long-timescale operation (60 min) of identical twin surface dielectric barrier discharges (twin SDBDs) powered either by a microsecond ( μ s) or nanosecond timescale (ns) voltage source is investigated. The SDBDs are characterized using current–voltage measurements, optical emission spectroscopy, and phase integrated ICCD imaging. temporally spatiall...

OBJECTIVES This in vitro study evaluated the capability of different soft drinks (Coca-Cola(R)-C, Coca-Cola Light(R)-CL, Guaraná(R)-G, Pepsi Twist(R)-P and Sprite Light(R)-SL) to erode dental enamel, relating the percentage of superficial microhardness change (%SMHC) to concentrations of fluoride and phosphate, buffering capacity and pH of these drinks. METHODS The soft drinks were evaluated ...

A real-time imaging electrochemical measurement system was developed for an in-situ observation of brass dezincification corrosion. This allows a video recording cross-section under galvanostatic polarization. The progress erosion associated with the corrosion in depth direction on successfully observed from during measurement. at each time could be estimated images, indicating that drastically...

The Three Gorges Reservoir Area is one of the most severe soil erosion in China. Serious erosion has degraded the soil productivity, deteriorated the ecological environment, and influenced the service life of Three Gorges Reservoir. The natural and social-economic factors which influence the soil erosion in Three Gorges Reservoir Area include topography, geological situation, vegetation, rainfa...

Potter, K. N., Williams, J. R., Larney, F. J. and Bullock, M. S. 1998. Evaluation of EPIC’s wind erosion submodel using data from southern Alberta. Can. J. Soil Sci. 78: 485–492. Wind erosion models have been used to assess policy impacts on soil erosion, but validation of models has been difficult until recently. We evaluated the Environmental Policy Integrated Climate (EPIC) wind erosion subm...
