In this work, EEG signals are used to detect the presence of pain in healthy subjects aiming to apply the same process to non-communicative patients. It was acquired 20 EEGs of healthy subjects in resting and pain state. Pain was induced through a cold pressor test. Phase Indexes as Phase Lag Index, Weighted Phase Lag Index were applied in four frequency bands to detect pain, getting significant results...
An activated carbon Carbochem™ – PS230 was modified by chemical and thermal treatment in flow of H 2 in order to evaluate the influence of the activated carbon chemical surface in the adsorption of the monohydroxylated phenols. The solid-solution interaction was determined by analyzing the adsorption isotherms at 298K at pH 7, 9 and 11 during 48h. The adsorption capacity of activated carbons...
