An UASB+Anoxic/Oxic (A/O) system was introduced to treat a mature landfill leachate with low carbon-to-nitrogen ratio and high ammonia concentration. To make the best use of the biodegradable COD in the leachate, the denitrification of NOx- -N in the recirculation effluent from the clarifier was carried out in the UASB. The results showed that most(More)
OBJECTIVE To study the relationship between HBeAg expression and HBV-DNA in serum and peripheral blood mononuclear cells (PBMCs). METHODS 208 patients with chronic hepatitis B were included in this present study. HBV-DNA in the PBMCs were performed by polymerase chain reaction (PCR), with the serum HBV-DNA level being determined by the way of fluoresces(More)
With the methods of compound-melting and high-temperature molding, PC/YAG:Ce fluorescent resin pieces were prepared. The transmittance of the prepared PC/YAG:Ce fluorescent resin in 500~800 nm reaches approximately 65% (0.71 mm thick, double sides polished). The fluorescent resin was characterized by XRD, SEM and PL. The X-ray diffraction (XRD) patterns(More)
OBJECTIVE To study the relationship between TCM syndrome type and HBV-DNA in serum and peripheral blood mononuclear cells (PBMCs) in chronic hepatitis B (CHB) patients. METHODS The serum HBV markers,HBV-DNA levels in serum and PBMCs, were quantitatively detected in 220 CHB patients by PCR method, and TCM syndrome type of 205 patients were differentiated.(More)
High-purity ultrafine MgAl2O4 powder was synthesized by metal-alkoxide method and calcining for 2-4 h. And then MgAl2O4/Ce:YAG transparent ceramics were fabricated by hot-pressed sintering and hot isostatic pressed sintering technique with YAG:Ce powder and MgAl2O4 powder. The transparent ceramics were characterized by XRD, SEM, EDS and fluorescence(More)
