The modeled properties are protein content, sodium dodecyl sulfate (SDS) sedimentation volume, number of hours during stone fill at temperature . 24 deg. C, and number of hours during stone fill at temperature > 32 deg. C. The size of the convolution window used to perform a smooth or second derivative is also examined.

An undergraduate laboratory experiment is presented that allows a thermodynamic characterization of micelle formation of sodium dodecyl sulfate (SDS) in aqueous solutions. The critical micelle concentration (CMC) and the degree of micelle ionization (α) are obtained at different temperatures by conductimetry.
