Four batch experiments of hydrolysis and acidification were carried out to investigate the distributions of proteins (PN) and polysaccharides (PS) in the sludge, the PN/PS ratio, the particle sizes, and their relationship with sludge dewaterability (as determined by capillary suction time, CST). The sludge flocs were stratified through centrifugation- and(More)
Peritoneal dialysis plays a crucial role in the integrated care of patients with end-stage renal disease (ESRD). In this paper, we retrospectively analyzed the quality indicators of peritoneal dialysis (PD) in 712 patients from our center who underwent PD between 2004 and 2011. In 43% of patients, follow-up was undertaken every 3 months at our outpatient(More)
A profiling analysis for the methanol extract of the seeds of Vaccaria hispanica (Mill.) Rauschert was performed using a HPLC-ESI-MS technique. Five compounds were identified according to their retention times, UV spectroscopic and MS features, and by comparison with literature data. Among them, a new flavonoid glycoside, named vaccarin H, was isolated and(More)
A simple and reliable HPLC method was developed and validated for the simultaneous quantification of four major constituents in Semen Vaccariae. The chromatographic separation was performed on an Agilent Zorbax SB-C18 column with gradient elution using methanol and water. The calibration curves showed good linearity of R2 > 0.9999 with LOQs (S/N = 10) of(More)
This paper described a study on the dynamic responses and injury risk of rear seat occupant in side impact. A PSM (Prescribed Structure Motion) model was created based on a passenger car model, which consists of car side structures, a SID-Ils dummy and rear seat in MADYMO environment. The structural responses of the vehicle body were obtained from the FE(More)
Automatic registration of terrestrial laser scanning point clouds is a crucial but unresolved topic that is of great interest in many domains. This study combines terrestrial laser scanner with a smartphone for the coarse registration of leveled point clouds with small roll and pitch angles and height differences, which is a novel sensor combination mode(More)
Supplier-induced demand has in fact been one of the most contentious topics in the economics of health care. According to the SID theory in health economics, the theoretical model about SID in China has been provided, then, based on the Co-integration theory, the empirical analysis has been brought out. The study tells that it is the reduction of government(More)
