1地下水铀污染的原位微生物还原与固定:在美国能源部田纳西橡树岭放射物污染现场的试验显示文摘总结了美国斯坦福大学和橡树岭国家实验室等在美国能源部田纳西州橡树岭综合试验基地进行的铀污染原位微生物修复阶段性试验结果.本试验利用微生物以乙醇为电子供体还原地下水和沉积物中的六价铀为不溶解的四价铀,使之原位固定化.随后通过加入溶解氧和硝酸盐来试验微生物还原后的地下水层中还原固定态铀的稳定性.通过预处理和长期间隔注入乙醇溶液,地下水中铀浓度从40~60mg·L-1降至0.03mg·L-1以下,达到了美国环保署饮用水的标准.还原的四价铀主要以U(Ⅳ)-Fe复合物的形态存在.结果表明,固定化后的四价铀只有在厌氧条件下才是稳定的,溶解氧和硝酸盐侵入地下水层后会使固定化的四价铀重新氧化为溶解态的六价铀.在试验过程中,采用多种分子生物学方法检测了微生物种群的变化和与铀氧化还原反应有关的功能微生物.本研究表明,在维持试验系统无氧和无硝酸盐的条件下,通过添加乙醇为电子供体可有效地促进地下水中土著功能微生物的活性,从而实现铀的原位还原固定与稳定.吴唯民 Jack Carley David Watson 顾宝华 Scott Brooks Shelly D.Kelly Kenneth Kemner Joy D.van Nostrand 吴力游 许玫英 周集中 罗剑 Erick Cardenas 黄家琪 Matthew W.Fields Terence L.Marsh James M.Tiedje Stefan J.Green Joel E.Kostka Peter K.Kitanidis Philip M.Jardme CraigS.Criddle 2011环境科学学报2011,31,3:28

3Study of the impact of the compaction and curing temperature on the behavior of cold bituminous recycled materials显示文摘In most countries, there is a low temperature limit to lay down hot asphalt mixes because if it is too cold, it becomes impossible to get proper compaction. For cold recycled bituminous mixture(CRM), there is little information on the effect of the low temperature on their behavior. The goal of this study is to evaluate, in laboratory, the impact of the compaction and curing temperature on the behavior of CRM. To do so, CRM containing 50%reclaimed asphalt pavement(RAP) and 50% natural aggregates treated with foamed asphalt or bituminous emulsion were mixed and cured at different temperature between 0 and23℃ for up to 10 days before being tested in indirect tension. The results show that for all mixes, a cure at lower temperature means lower tensile strength, but the decrease is more noticeable for emulsion treated materials than for foamed treated mixes. The trend is not as obvious for Marshall stability results. A second cure at ambient temperature was also done, and the analysis of the results showed that the decrease in mechanical performance remains important even after a second cure at higher temperature for all mixes treated with bituminous emulsion, but there is some mechanical gain for mixes treated with foamed asphalt.Apparao Gandi Alberto Cardenas Djibril Sow Alan Carter Daniel Perraton 2019Journal of Traffic and Transportation Engineering(English Edition)2019,6,4:4
4Analysis of the therapeutic evolution in the management of airway infantile hemangioma显示文摘AIM: To analyze the evolution in the management of airway infantile hemangioma(AIH) and to report the results from 3 pediatric tertiary care institutions.METHODS: A retrospective study of patients with diagnosis of AIH and treated in 3 pediatric tertiary care institutions from 1996 to 2014 was performed. RESULTS: Twenty-three patients with diagnosis of AIH were identified. Mean age at diagnosis was 6 mo(range, 1-27). Single therapy was indicated in 16 patients and 7 patients received combined therapy. Two therapeutic groups were identified: Group A included 14 patients who were treated with steroids, interferon, laser therapy and/or surgery; group B included 9 patients treated with oral propranolol. In group A, oral corticosteroids were used in 9 patients with a good response in 3 cases(no requiring other therapeutic option), the other patients required additional treatment options. Cushing syndrome was observed in 3 patients. One patient died of a fulminant sepsis. Open surgical excision and endoscopic therapy were performed in 11 patients(in 5 of them as a single treatment) with a response rateof 54.5%. Stridor persisted in 2 cases, and one patient died during the clinical course of bronchial aspiration. In group B, oral propranolol was used in 9 patients(in 8 of them as a single treatment) with a response rate of 100%, with an mean treatment duration of 7 mo(range, 5-10); complications were not observed. CONCLUSION: Our experience and the medical literature support the use of propranolol as a first line of treatment in AIH.Grecia V Vivas-Colmenares Israel Fernandez-Pineda Juan Carlos Lopez-Gutierrez Miguel Angel Fernandez-Hurtado Maria Antonia Garcia-Casillas Jose Antonio Matute de Cardenas 2016World Journal of Clinical Pediatrics2016,5,1:3
