Diazinon pesticide and its metabolites have been identified in aquatic systems worldwide. It was related to toxicity for aquatic organisms, animals, and humans. Waters contaminated with such persistent insecticides should be treated with suitable treatment processes. In this research, Diazinon removal from aqueous solutions by the photo–Fenton–like process (UV/H2O2/Fe...

Docolorization of Methylene Blue was investigating using a Ultrasonic/Fenton like reactor in batch mode. The effects of pH, reaction time, initial concentration of dye, H2O2 and Fe on the dye removal was studied. It was found that the increase of initial dye and H2O2 concentration and the increase of initial pH, are not beneficial for improving the dye removal efficiency. Increasing the dye con...

This paper deals with the asymptotic behavior when the level tends to +1, of the tail of the distribution of the maximum of a stationary Gaussian process on a xed interval of the line. For processes satisfying certain regularity conditions, we give a second order term for this asymptotics.

We report our observations that the baby-Skyrme model in (2+1) dimensions possesses non-topological stationary solutions which we call psedo-breathers. We discuss their properties and present our results on their interaction with the topological skyrmions.
