"The annual balances of population by nationality (live births by mother's nationality, deceased and migrants by their nationality) [allow us] to calculate the volume of nationality assimilation after each population census as well as so called ¿bending over of nationality' [declaring a nationality not one's own] when we compare the balance and the results of population census by nationality...

A procedure is proposed for the calculation of the actual effective mobility of a zone from its migration time. It is based on the use of internal standards with known mobilities; the use of two internal standards provides reliable mobility data even if the magnitudes of the effects of sample composition, capillary temperature, capillary length, migration distance, used voltage, as well as the tube length occupied by the injected sample are unknown. Formulas have been derived for the calculation of the actual mobilities, and their experimental verification has been carried out by using a model set of anionic solutes with mobilities ranging from -56 to -20 x 10(-9) m2V-1s-1 and chloride as the ion modelling the effect of the sample matrix.
