1重稀土元素钇对短程反硝化工艺的影响显示文摘研究重稀土元素钇(Y(Ⅲ))对短程反硝化工艺的短期和长期影响.结果表明,1~50mg/L的Y(Ⅲ)对亚硝酸盐的积累量无明显影响,60~100mg/L的Y(Ⅲ)会影响硝酸盐的还原和亚硝酸盐的积累.1~10mg/L的Y(Ⅲ)对细菌活性呈现促进作用,20~100mg/L的Y(Ⅲ)对细菌活性呈现抑制作用.胞外吸附的Y(Ⅲ)是抑制细菌活性的主要因子,线性拟合的相关性系数R2为0.957,半抑制浓度IC50(吸附)为1.079mg/L(以湿重计),对应水中Y(Ⅲ)浓度为54.35mg/L.SEM显示,添加Y(Ⅲ)会使细菌产生更多的胞外聚合物(EPS)将细菌包裹以抵抗Y(Ⅲ)的毒性,EDS显示被包裹的细菌表面碳、氮元素含量大幅度降低,EPS影响了底物的传质.130d的长期实验表明,5mg/L的Y(Ⅲ)会使反应器的反硝化性能逐渐消失,停止添加稀土后,反应器的亚硝酸盐积累功能也不能恢复.赖城 周豪 张大超 董冰岩 Philip Antwi 苏昊 石淼 2021中国环境科学2021,41,7:9

4短程反硝化/厌氧氨氧化工艺研究进展显示文摘厌氧氨氧化是非常有前景的生物脱氮工艺,但由于短程硝化的局限性,厌氧氨氧化工艺一直难以全面推广,而短程反硝化的提出则弥补了这一缺陷。近些年短程反硝化的研究已经取得诸多成果,首先回顾了反硝化过程中影响亚硝酸盐积累的因素,综述了成功启动短程反硝化的富集实验,分析了菌群特性和亚硝酸盐积累机理,总结了反应器启动条件,并指出了现有研究中的不足之处,认为探明短程反硝化功能菌的富集机理和种间选择机制能够更好地促进短程反硝化的发展。随后综述了短程反硝化/厌氧氨氧化组合工艺的研究现状并展望了其应用前景。赖城 张大超 Philip Antwi 董冰岩 周豪 苏昊 石淼 2021环境污染与防治2021,43,11:2

9Evaluation of the robusticity of mutual fund performance in Ghana using Enhanced Resilient Backpropagation Neural Network(ERBPNN)and Fast Adaptive Neural Network Classifier(FANNC)显示文摘Mutual fund investment continues to play a very important role in the world financial markets especially in developing economies where the capital market is not very matured and tolerant of small scale investors.The total mutual fund asset globally as at the end of 2016 was in excess of$40.4 trillion.Despite its success there are uncertainties as to whether mutual funds in Ghana obtain optimal performance relative to their counterparts in United States,Luxembourg,Ireland,France,Australia,United Kingdom,Japan,China and Brazil.We contribute to the extant literature on mutual fund performance evaluation using a collection of more sophisticated econometric models.We selected six continuous historical years that is 2010-2011,2012-2013 and 2014-2015 to construct a mutual fund performance evaluation model utilizing the fast adaptive neural network classifier(FANNC),and to compare our results with those from an enhanced resilient back propagation neural networks(ERBPNN)model.Our FANNC model outperformed the existing models in terms of processing time and error rate.This makes it ideal for financial application that involves large volume of data and routine updates.Yushen Kong Micheal Owusu-Akomeah Henry Asante Antwi Xuhua Hu Patrick Acheampong 2019Financial Innovation2019,5,1:1
