We analyze the problem of reliably estimating uncertainties of the earthquake source spectrum and related source parameters using Empirical Green Functions (EGF). We take advantage of the large dataset available from 10 seismic stations at hypocentral distances (10 km < d < 50 km) to average spectral ratios of the 2001 M5.1 Anza earthquake and 160 nearby aftershocks. We estimate the uncertainty...

In the present research, salting out and vortex assisted dispersive liquid–liquid microextraction based on solidification of floating organic drop microextraction (SO-VADLLME-SFODME)  for the extraction and determination of phenol and chlorophenols in water samples followed by HPLC have been studied through a novel, simple, low-cost, selectable and environment friendly (so called green) method....
