Es inevitable la producción de residuos que constituyen el último eslabón de cualquier actividad industrial. El incremento en el volumen de descartes industriales, la simultánea disminución de los espacios de dispos...

Fueron obtenidos tres derivados del ácido N-fenilantranílico; de ellos, el derivado nitrado no ha sido reportado en la literatura consultada. Mediante la ciclización de estos ácidos se obtienen las acridonas correspo...

Abstract We present the theoretical and technical foundations of the Amsterdam Density Functional (ADF) program with a survey of the characteristics of the code (numerical integration, density fitting for the Coulomb pot...
