Vladimir Feldman (Moscow U) Q: How can we purify water using solvated electron? ... However, they cannot help, when we deal with some very important toxic contaminations, which are not readily oxidized (heavy metal ions, chlorinated compounds, etc.) ... The examples of these reactions were given shown in lecture. ... Indeed, irradiation of water with fast electrons produces both strong oxidizer (OH radical) and very efficient reducing species (hydrated electron) in nearly balanced amounts. ...

The results of simulation are compared in the case of using a number of reduced and detailed schemes for formaldehyde and hydrogen oxidation reactions. Keywords: sensitivity analysis, mathematical model of reaction, formaldehyde oxidation reaction, hydrogen oxidation reaction, reduction of chemical reaction mechanisms. ...
... Application of the change-point analysis to the investigation of the brain's electrical activity. ... A vast variety of approaches to the extraction of quantitative features from an EEG signal was introduced during more than 70 years of electroencephalography. ... Therefore, statistical approaches seem to be the most feasible and theoretically satisfactory methodology for the quantitative analysis of the EEG signal up to now. ...
