an efficient dispersive liquid-liquid microextraction using tetraalkylammonium bromide coated silver nanoparticles (dllme-agnps) prepared in chloroform has been successfully applied as electrostatic affinity probes to the microextraction and preconcentration of terazosin prior to spectrofluorimetry analysis. this technique is based on a ternary system of solvents, where appropriate amount of mi...

This paper describes a new comparison principle that can be used for the comparison of space-time estimates for dispersive equations. In particular, results are applied to the global smoothing estimates for several classes of dispersive partial differential equations.

In this paper we study local well-posedness in the energy space for a family of dispersive equations that can be seen as dispersive " interpolations " between the KdV and the Benjamin-Ono equation.

The effect of heterogeneity on seawater intrusion is analyzed. Heterogeneity in hydraulic properties such as hydraulic conductivity is well known to significantly affect groundwater flow and solute transport. Yet, few studies [Mc Kribbin and O`Sullivan, 1980; Schincariol and Schwartz, 1990; Schincariol et al., 1997 and 1998; Simmons et al., 2001] have focused on evaluating the impact of heterog...
