1Spatiotemporal dynamics of carbon intensity from energy consumption in China显示文摘持续发展被全球气候变化严重由于碳排出物质问了。作为一个发展中的乡村,中国答应了在 2020 在在它的碳紧张上的一年 2005 的水平下面减少 40%-45% 。这个目标的实现在精力在省的规模节省和排出物减小的国家规模,而且行动和份额取决于社会和经济的不仅真实转变。基于 IPCC 提供的方法,这份报纸在 19972010 从精力消费检验空间与时间的动力学和瓷器碳紧张的统治因素。目的是为政策在中国在精力保存和碳排放减小上做提供科学基础。结果如下被显示出。第一,瓷器碳排出物从 1997 ~ 2010 从 4.16 Gt 增加了到 11.29 Gt,与 7.15% 的年度生长率,它比 GDP (11.72%) 的低得多。第二,那瓷器碳紧张有一变得空间的我显示了的 Morans 的趋势在省的规模的凝块。有高或低的价值的省看起来是路径依赖者或对某程度锁空间。第三根据空间面板 econometric 模型的意见,精力紧张,精力结构,工业结构和都市化率是从精力塑造瓷器碳紧张的空间与时间的模式的统治因素消费。因此,以便实现精力保存和排放减小的目标,中国应该改进精力利用的效率,优化精力和工业结构,选择低碳的都市化途径并且实现精力的地区性的合作策略保存和排出物减小。CHENG Yeqing WANG Zheye YE Xinyue WEI Yehua Dennis 2014Journal of Geographical Sciences2014,24,4:40
2A novel Z-scheme CeO_(2)/g-C_(3)N_(4)heterojunction photocatalyst for degradation of Bisphenol A and hydrogen evolution and insight of the photocatalysis mechanism显示文摘CeO_(2)/g-C_(3)N_(4)heterojunction photocatalyst had been successfully fabricated through a one-step in-situ pyrolysis formation of 3D hollow CeO_(2)mesoporous nanospheres and 2D g-C_(3)N_(4)nanosheets together with simultaneous removal of carbon sphere templates after heat treatment.The sample shows high catalytic performances for photocatalytic hydrogen generation and photocatalytic oxidation of Bisphenol A(BPA)under visible light irradiation,and the catalytic degradation route of BPA was suggested by the degradation products determined by GC-MS.The enhancing catalytic activity was attributed to the effective interfacial charge migration and separation.Finally,it was proposed that the CeO_(2)/g-C_(3)N_(4)heterojunction photocatalyst could follow a more appropriate Z-scheme charge transfer mechanism,which was confirmed by the analysis of experiment and theoretical calculation results.Wei Zhao Tiantian She Jingyi Zhang Guoxiang Wang Sujuan Zhang Wei Wei Gang Yang Lili Zhang Dehua Xia Zhipeng Cheng Haibao Huang Dennis Y.C.Leung 2021Journal of Materials Science & Technology2021,,26:3
3Effects of Ca(OH)_2 assisted aluminum sulfate coagulation on the removal of humic acid and the formation potentials of tri-halomethanes and haloacetic acids in chlorination显示文摘The effects of addition of calcium hydroxide on aluminum sulphate(or alum) coagulation for removal of natural organic matter(NOM) and its subsequent effect on the formation potentials of two major types of regulated disinfection byproducts(DBPs),haloacetic acids(HAAs) and trihalomethanes(THMs),have been examined.The results revealed several noteworthy phenomena.At the optimal coagulation pH(i.e.6),the coagulation behavior of NOM water solutions versus alum dose,showed large variation and a consequent great change in the formation potentials of the DBPs at certain coagulant doses.However,with addition of a relatively small amount of Ca(OH) 2,although the zeta potential of coagulated flocs remained almost the same,NOM removal became more consistent with alum dose.Importantly,also the detrimental effect of charge reversal on NOM removal at the low coagulant dose disappeared.This resulted in a steady decrease in the formation potentials of DBPs as a function of the coagulant dose.Moreover,the addition of Ca(OH) 2 broadened the pH range of alum coagulation and promoted further reduction of the formation potentials of the DBPs.The enhancement effects of Ca(OH) 2 assisted alum coagulation are especially pronounced at pH 7 and 8.Finally,synchronous fluorescence spectra showed that the reduction in DBPs formation potential by Ca(OH) 2-assisted alum coagulation was connected to an enhanced removal of small hydrophobic and hydrophilic HA molecules.Ca(OH) 2-assistance of alum coagulation appeared to increase substantially the removal of the hydrophilic HA fraction responsible for HAAs formation,prompting further reduction of HAA formation potentials.Jinming Duan Xiaoting Cao Cheng Chen Dongrui Shi Genmao Li Dennis Mulcahy 2012Journal of Environmental Sciences2012,24,9:3

5Trend Analysis of Cancer Mortality in the Jinchang Cohort, China,2001-2010显示文摘Objective To describe the baseline data of cancers in the Jinchang Cohort, this paper examined trends in cancer mortality among adults investigated in Jinchang, Gansu province from 2001 to 2010. Methods Mortality data were collected from company departments through administrative documents, death certificates, etc. Trend analyses of cancer mortality were performed on the basis of 925 cancer deaths between 2001 and 2010. Results The crude mortality rate of cancer continuously increased from 161.86 per 100,000 in 2001 to 315.32 per 100,000 in 2010, with an average increase of 7.69% per year in the Jinchang Cohort(16.41% in females compared to 6.04% in males), but the age-standardized mortality rate increased only in females. Thirteen leading cancers accounted for 92.10% of all cancer deaths. The five leading causes of cancer mortality in males were lung, gastric, liver, esophageal, and colorectal cancer, whereas those in females were lung, liver, gastric, breast, and esophageal cancer. Conclusion The overall cancer mortality rate increased from 2001 to 2010 in the Jinchang Cohort, with greater rate of increase in females than in males. Lung, breast, and gastric cancer, in that order, were the leading causes of increased cancer mortality in females.QU Hong Mei BAI Ya Na CHENG Ning DAI Min ZHENG Tong Zhang WANG Dennis LI Hai Yan HU Xiao Bin LI Juan Sheng REN Xiao Wei SHANG Hui 2015Biomedical and Environmental Sciences2015,28,5:2
