A long-term pilot-scale H_(2)-based membrane biofilm reactor(mBfR)was tested for removal of nitrate from actual groundwater.A key feature of this secondgeneration pilot mBfR is that it employed lower cost polyester hollow fibers and still achieved high loading *** steady-state maximum nitrate surface loading at which the effluent nitrate and nitrite concentrations were below the maximum Contaminant Level(mCL)was at least 5.9 g·N·(m^(2)·d)^(–1),which corresponds to a maximum volumetric loading of at least 7.7 kg·N·(m^(3)·d)^(–1).The steady-state maximum nitrate surface area loading was higher than the highest nitrate surface loading reported in the firstgeneration mBfRs using composite fibers(2.6 g·N·(m^(2)·d)^(–1)).This work also evaluated the H_(2)-utilization efficiency in *** measured H_(2)supply rate was only slightly higher than the stoichiometric H_(2)-utilization ***,H_(2)utilization was controlled by diffusion and was close to 100%efficiency,as long as biofilm accumulated on the polyester-fiber surface and the fibers had no leaks.

A ciliated hepatic foregut cyst (CHFC) is a rare foregut developmental malformation usually diagnosed in adulthood. Five percent of reported cases of CHFC transform into squamous cell carcinoma. We report the presentation, evaluation, and surgical management of a symptomatic 45-year-old male found to have a 6.2 cm CHFC. Contrast tomography-guided fine-needle aspiration demonstrated columnar, ciliated epithelium consistent with the histologic diagnosis of CHFC. The intracystic levels of carbohydrate antigen (CA) 19-9 and carcinoembryonic antigen (CEA) were extremely high (978118 U/mL and 973 μg/L, respectively). Histologically, the wall of the cyst showed characteristic pseudopapillae lined with a ciliated stratified columnar epithelium, underlying smooth muscle, an outer fibrous layer and no atypia. Immunohistochemistry for CA19-9 and CEA was positive. This is the first case report of a CHFC in which levels of CA 19-9 and CEA were measured. Our findings suggest that a large sized multilocular cyst and elevated cyst CA19-9 and CEA levels do not exclude a CHFC from consideration in the diagnosis. CHFCs should be included in the differential diagnosis of hepatic lesions. Accurate diagnosis of a CHFC is necessary given its potential for malignant transformation, and surgical excision is recommended.

本研究的主要目标是检验地震触发是否存在更低的阈值.解决这个问题对于理解地震机制及灾害分析来说都是十分重要的。我们通过叠加每个 m≥4.5地震前所有前面的 m≥4.5地震产生的应力变化,求出这种变化的时间函数,从而计算加在1969～1998年间加利福尼亚中部的63个 m≥4.5地震上的累积静态应力变化。我们发现,应力变化量级>10 kPa(>0.1 bar)时,地震破裂时85%的累加应力变化为正,应力变化<10 kPa(<0.1 bar)及<1 kPa 时,70%为正。将这些结果与地震时间或震源机制随机的合成地震目录作比较,说明这种触发的程度几乎不可能在随机目录中找到.因此,我们的结论是,在加利福尼亚中部至今未发现地震触发的应力下限.我们的结果表明,抑制破裂应力变化的时间分布与时间延迟随应力变化增大而加长的理论预测是一致的。
