ABSTRACT
Mónico Sánchez Moreno (1880-1961) was an important figure in the early years of electromedicine, rubbing elbows with world-class physicists like Nikola Tesla. Her main contribution to the field was the invention and commercialization of a portable X-ray generator, replacing the heavy transformer had been necessary to generate power with a lightweight portable device that could work with direct or alternating current at 220 or 125V. This device was easily adaptable to other applications in electromedicine, such as cauterization or disinfection. This indefatigable entrepreneur could have triumphed in America, but preferred to work toward furthering technological development in the land that she loved. Her efforts made it possible to have an affordable device made in Spain that would allow radiological examinations to be done in places where it would have been otherwise unthinkable. In conclusion, Mónico Sánchez Moreno was a self-made woman who deserves to be remembered for her pioneering role in portable radiology.

Mónico Sánchez Moreno (1880-1961) fue un personaje destacado en los primeros años de la electromedicina, llegando a codearse con figuras encumbradas de la física mundial como Nikola Tesla. Su principal aportación fue la invención y comercialización de un generador portátil de rayos X, sustituyendo el pesado transformador que se requería para generar corriente por un equipo ligero, portátil, que funcionaba con corriente continua o alterna, a 220 o 125 V, fácilmente adaptable para otras aplicaciones de electromedicina como la cauterización o la desinfección. Este emprendedor infatigable, que podía haber triunfado en América, prefirió invertir su esfuerzo en impulsar el desarrollo tecnológico en la tierra que amaba, permitiendo disponer de un equipo de fabricación nacional, asequible, que pudo llevar la exploración radiológica a rincones impensables de otro modo. En conclusión, Mónico Sánchez Moreno fue un hombre hecho a sí mismo, que merece ser recordado como pionero de la radiología portátil.(AU)

ABSTRACT
The different fluorescence lifetime profiles of the optical isomers (+)-cinchonine (CN) and (-)-cinchonidine (CD) have been used to resolve their mixtures, on the basis of phase and modulation fluorescence lifetime measurements. To resolve mixtures of these compounds two distinct approaches have been used: simultaneous equations from phase-resolved and modulation-based fluorescence lifetime measurements. Results indicate that frequency domain fluorimetry is useful to resolve stereomeric compounds for determination without physical separation. The precision of the measurements gives RSD values of 5.2% and 4.0% for CD and CN, respectively. Detection limits with the modulation fluorescence lifetime method were 11.3 and 17.2 microM for CD and CN, respectively.
