利用1988—2017年珠江河口三灶站潮位、澳门风速、上游流量日极值数据,基于广义可加模型(GAMLSS)的非一致性频率计算方法与时变Copula函数,对上游洪水、台风和天文潮的复合洪水事件重现期及其主控因子展开研究,结果表明:1)珠江河口区潮位、风速、流量均为非一致性序列,构建的时变Copula模型相比传统恒定参数的Copula更符合实际情况。2)1988—2017年珠江河口区典型复合洪水事件发生周期随时间不断缩短,发生概率增大,未来极端复合洪水事件发生概率增强。“黑格比”台风引发的复合洪水事件重现期从1988年的13.06 a一遇减小到2017年的10.80 a一遇,“韦森特”“天兔”引发的复合洪水事件在1988—2017年重现期缩短了1.06和0.97 a;3)当3种因子重现期为5 a一遇时,珠江河口区复合洪水事件主要受台风风速影响较大;重现期为10、20、50 a一遇时,复合洪水事件主要受天文潮潮位影响较大。

Journal of Environmental Sciences 2013年第10期25卷 2157-2167页

作者： N.Clament Sagaya selvam S.Narayanan L.John Kennedy J.Judith Vijaya Catalysis and Nanomaterials Research Laboratory Department of Chemistry Loyola College Materials Division School of Advanced Sciences Vellore Institute of Technology UniversityChennai Campus

A novel self-assembled pure and Mg doped ZnO nano-particles （NPs） were successfully synthesized by a simple low temperature co-precipitation method. The prepared photocatalysts were characterized by X-ray diffraction, high resolution scanning electron mi- croscopy, high resolution transmission electron microscopy, diffuse reflectance spectroscopy and photoluminescence （PL） spectroscopy. The results indicated that the prepared photocatalysts showed high crystallinity with a uniform size distribution of the NPs. The degradation of cholorphenols is highly mandatory in today＇s scenario as they are affecting the environment adversely. Thus, the photocatalytic degradation of 4-chlorophenol （4-CP）, a potent endocrine disrupting chemical in aqueous medium was investigated by both pure and Mg-doped ZnO NPs under UV-light irradiation in the present study. The influence of the Mg content on the structure, morphology, PL character and photocatalytic activity of ZnO NPs were investigated systematically. Furthermore,the effect of different parameters such as 4-CP concentration, photocatalyst amount, pH and UV-light wavelength on the resulting photocatalytic activity was investigated.

We present CCD photometric observations of an eclipsing binary in the direction of the open cluster Praesepe using the 2 m telescope at IUCAA Girawali Observatory, India. Though the system was classified as an eclipsing binary by Pepper et al., detailed investigations have been lacking. The photometric solutions using the Wilson-Devinney code suggest that it is a W-type W UMa system and, interestingly, the system parameters are similar to another contact binary system SW Lac.
