通过考察水力停留时间(hRT)和泥龄(SRT)对A2/O系统去除碳(c)、氮(N)、磷(P)的影响,对系统的运行参数进行优化,并分析了c、N、P三种元素在最佳工况下的物料平衡和质量分布。结果表明,hRT对系统去除cOD、TN和TP的影响不大,当hRT>8h时,系统对各指标的去除率已基本不再变化;系统对TN的去除率随SRT的减小而减小,对TP的去除率随SRT的减小而增大,对cOD的去除率受SRT的影响较小;综合考虑系统的除碳脱氮除磷效果,确定最佳的hRT为8h、SRT为15d,此时系统中c、N和P的平衡百分比分别为82.2%、95.2%和95.1%,其中进水cOD主要以cO2的形式(66.2%)被去除,TN主要以N2的形式(59.0%)被去除,TP主要由剩余污泥(84.4%)带出系统。

文章研究了在700℃退火下,铝插入层调制镍和硅锗合金反应形成单相镍硅锗化物的生长机理.透射电镜测试结果表明,镍硅锗薄膜和硅锗衬底基本达到赝晶生长;二次质谱仪和卢瑟福沟道背散射测试结果表明,在镍硅锗薄膜形成的过程中,铝原子大部分移动到镍硅锗薄膜的表面.研究结果表明,铝原子的存在延迟了镍和硅锗合金的反应,镍硅锗薄膜的热稳定性和均匀性都得到了提高.最后,基于上述实验结果给出了铝原子调制形成外延镍硅锗薄膜的生长机理.

南堡凹陷滩海区深部古生界已相继发现数口高产工业油气流井,其性质不同于上伏第三系原油。采用地质地球化学方法相结合途径,对油气特征与成因进行了剖析。已发现潜山原油主要为高蜡油、其次为凝析油。Gc、Gc/MS分析表明,潜山原油中链烷烃组分含量较高、甾萜类生标含量较低且异构化程度较高;富含重排甾烷、重排藿烷与18a(h)-新降藿烷(Ts)与c29Ts;部分生标如升藿烷系列有明显热裂解现象,指示潜山原油较高的成熟度。油—油、油—岩对比表明,潜山原油与沙二+三段烃源岩有成因联系。供烃方式主要包含近距离—烃源岩直接披覆于潜山及源—储通过断层对接供烃、远距离—断层和风化壳运移输导两种。南堡凹陷潜山高蜡油的形成主要与烃源岩主要为Ⅱ2-Ⅲ型有机质类型有利于提供蜡质烃以及深部奥陶系油气藏极可能遭受气洗有关。气洗迹象包括低分子量链烷烃被切割、萘系列相对丰度低于菲系列,出现"倒转"等反常现象。南堡凹陷潜山油气特征与成因研究有助于揭示该区深部油气藏的形成机制及开展深部油气资源评价。

口腔原发性恶性黑色素瘤:1例报道

世界核心医学期刊文摘（皮肤病学分册） 2005年第3期1卷 16-17页

作者： Ortega K.L. de Araú jo N.S. de Souza F.B. Magalh.aes M.h.c.G. 刘超 Faculdade de Odontologia Departamento de Patologia Bucal Cidade Un iversitá ria Lineu Prestes 2227 05508- 900 S.ao Paulo SP BrazilDr.

A 43-year-old white man was referred to the Special care Dentistr y center of the School of Dentistry,university of Sao Paulo, Brazil, for the diagnosis o f an extensive nodular lesion of the maxillary gingiva. The patient complained t hat his left maxilla had swollen over the last 4 months, with some exudation fro m the gingival crevice, sporadic bleeding, and slight tooth mobility, but no pai n. An extra-oral examination confirmed expressive swelling of the left side of the face (Fig. 1A). Palpation disclosed bilateral enlargement of the submandibu lar lymph nodes. An intra-oral examination showed an extensive, reddish, nodul ar mass (around 11 cm in diameter) that extended from the last left maxillary mo lar to the right maxillary incisor, covered by a mucosa that was ulcerated in so me areas (Fig. 1B,c). Palpation revealed a painless, soft, bleeding tissue that seemed to arise in the periodontal ligaments, extending to the palate and vestibular area. A small pigmented spot was found in the palat al mass. histopathologically, the biopsy revealed a proliferation of neoplastic cells that exhibited a wide variety of shapes, including spindle, plasmacytoid, and epithelioid forms. The atypical cells showed enlarged and pleomorphic nuclei . Mitotic activity and pigmented areas were observed (Fig. 2A,B). Immunohistoche mistry was used to establish the final diagnosis. The tumor cells strongly expre ssed S100 protein, gp100 (hMB- 45), melan A, and tyrosine antibodies (Fig. 2c,D ). With the diagnosis of malignant melanoma, the patient was referred to an onco logist for treatment. As computed tomography revealed that the lesion was deeply inserted into the skull surface (Fig. 1D), surgical intervention was not possib le. The patient underwent radiotherapy, but died 14 months later.

Williams syndrome (WS) is a well- recognized neurodevelopmental disorder man ifested by both connective tissue and cNS abnormalities. The study depicts the 8 - y experience and follow- up of 50 Greek children with the clinical diagnosis of WS. clinical data on the facial features and cardiovascular, endocrinologic, and neurodevelopmental evaluation are presented. The most consistent findings w ere dysmorphic features (100% ), followed by dental anomalies (90% ) and hyper acousis (90% ). Only eight of 50 children had severe cardiovascular defects tha t required surgical intervention during the first year of life. Supravalvular ao rtic stenosis was less frequent (28% ) than shown in the literature. Severe hyp ertension was noticed in 22% of our patients, and infantile hypercalcemia was noticed in 6% . Twelve percent of our patients showed an elevation of cPK. Most children presented with moderate to severe mental retardation with IQ ranging f rom 20 to 85. Elastin hemizygosity was detected by fluorescence in situ hybridiz ation. Dinucleotide repeat polymorphism analysis was performed in an attempt to correlate phenotype with genotype. The origin of deletions was more frequently m aternal (59% ), and a more severe phenotype seemed to be associated with those deletions. This is the first report on WS patients in the Greek population.

复发性脱髓鞘性脊髓炎与丙肝病毒感染有关

世界核心医学期刊文摘（神经病学分册） 2005年第2期1卷 50-51页

作者： Grewal A.K. Lopes M.B. Berg c.L. 李一明

We report a 46 year old man who developed recurrent myelitis associated wit h hepatitis c viral (hcV) infection. Spinal cord biopsy showed acute demyelinati on without evidence of vasculitis. Antibodies to hcV were present in the cSF;hcV RNA was not detected in the cSF. Neither hcV antigens nor RNA were detected in the spinal cord biopsy, whereas they were found in the liver biopsy. Evaluation for other infectious or autoimmune causes was unrevealing. These observations su ggest that recurrent myelitis in this patient is etiologically related to hcV in fection, possibly via an immune mediated mechanism. This is the first report of pathologically proven myelitis associated with hcV infection and we suggest tha t hcV be considered in the differential diagnosis of the transverse myelitis syn drome.
