The cetylpyridinium chloride turbidity screening test for glycosaminoglycan excretion discussed by Manley, Severn, and Hawksworth (1968) has been used in this laboratory. In this method (cetylpyridinium chloride turbidity) the precipitation time of four minutes is critical since, after this time interval, turbidity may continue to rise or may fall due to aggregation of particles. As a result of...

The Zhuozishan West Piedmont Fault (ZWPF) is an active normal fault in the northwestern corner of Ordos Block. Studying recurrence characteristics paleoearthquakes useful for understanding regional seismic hazard potential. In this study, paleoseismic trench and optically stimulated luminescence (OSL) dating methods are used to determine temporal sequence paleoearthquakes. Severn earthquakes we...
