Spontaneous abortion after transcervical chorionic villus sampling: A case report

A case of spontaneous abortion after transcervical CVS is presented. Despite no evidence of bacteria in the vagina and cervix prior to sampling and the prophylactic use of Metronidazole, pathological evidence of chorioamnionitis was found. The implications of this are discussed.     

Stability analysis of alkaline nitrobenzene-containing wastewater by a catalyzed Fe-Cu treatment process

Iron and copper bimetallic system (catalyzed Fe-Cu process) is a promising technology for alkaline nitrobenzene-containing wastewater treatment. However, little is currently known about the changes of treatment efficiency with time going. This research investigated the long-term performance of the catalyzed Fe-Cu process to reduce nitrobenzene (NB) in alkaline wastewater. In addition, the changes of the metal surfaces morphologies and matters before and after the reaction were analyzed by scanning electron microscopy (SEM) in conjunction with energy-dispersion spectroscopy (EDS) and X-ray diffraction spectroscopy (XRD). The results showed that the surface properties of copper almost remained unchanged after weeks of operation, which spelled its strong chemical stability and resistance to poisoning. Moreover, the results indicated that there were two reasons for the treatment efficiency decreasing with time. One was the gradual iron element consumption due to corrosion. The other was iron reactivity weakened due to the precipitates accumulation on the surfaces that were mainly Fe₃O₄ and FeCO. __________ Translated from Environmental Pollution & Control, 2006, 28(10): 783–785 [译自: 环境污染与防治]     

三峡库区滑坡地带岩石特性的研究

针对三峡库区组成滑坡岩层的主要岩石——泥质岩、灰岩、砂岩,通过显微镜观察、X射线分析显微镜的定量分析及室内岩石力学强度试验,对各岩石的特性进行了分析。显微镜及X射线定量分析结果表明风化较弱的泥质岩基本上含有石英与钙质矿物,后者由于易溶于水而导致岩石的孔隙率增加。孔隙的一部分连接形成了裂缝, 从而使岩石的强度下降。各岩石的单轴压缩试验结果表明砂岩的强度最高,发生了风化的泥质砂岩的强度最低。在饱和状态下紫红色泥岩及风化了的泥质砂岩的单轴压缩强度降低最显著,比自然干燥状态下降低了大约50%, 推测是受粘土矿物含量的影响。所有岩石都表现出在峰值强度之前应力与应变几乎呈线性关系,而峰值强度之后应力急剧下降的脆性特征。这种在饱和状态下岩石强度大幅度下降与脆性特征表明在治理滑坡时需要采取十分周密及复杂的预防措施。     

一种新型复合式生物流化反应器混合特性的研究

对新型蜂窝状断面复合生物流化反应器进行了液体循环速率和水力停留时间分布曲线的测定，实验表明新型反应器具有抗冲击负荷强，接近CSTR反应器的特点，反应器随气量增大、载体投加量减少和进水量减少而更近似于CSTR反应器，通过理论分析，证明了影响液体循环速率的参数主要有气体流量(气含率)、反应器沿程和局部阻力系数以及Ad/Ar，并且得出液体循环速率与反应器高度的0．5次方成正比。

Detection of Escherichia coli in wastewater based on enzyme immunoassay

This research describes a fast detection method on the basis of enzyme-linked immunosorbent assay (ELISA) for Escherichia coli in drainage of wastewater treatment plants. Optimized conditions such as the reaction format (sandwich or direct), the concentrations of diluted horseradish peroxidase (HRP)-E. coli conjugate, and anti-HPR antibody and pretreatment of E. coli were studied. Those results showed that the linear range of detection for E. coli was 10 cfu/mL-6 × 10⁴ cfu/mL. Compared with conventional methods, it is a convenient and sensitive detection method with low cost.
