Copper Tungstate-Graphene Oxide nano composites have been successfully applied as excellent catalysts for the photocatalytic degradation with Methylene blue and Malachite green dyes under visible light irradiation. A facile?solid state metathesis synthesis of copper tungstate (CuWO4) followed by ball milling and subsequent preparation of copper tungstate-graphene oxide?(CuWO4-GO) nano composite using a colloidal blending process and its application as a visible light photocatalyst for the degradation of Malachite green and Methylene blue dyes. The morphology and composition of copper tungstate (CuWO4) nano composite have been characterized using X-Ray Diffraction (XRD), UV-Visible Diffuse Reflectance Spectra (UV-DRS), raman Spectra, Field Emission Scanning Electron Microscopy (FESEM)-EDS and UV Visible Spectroscopy. It shows a band gap value of 2.13 eV, an increase in range and intensity of light absorption and the reduction of electron-hole pair recombination in CuWO4 with the introducing of GO on to it.

Dielectric Properties of Ni-Zn Ferrites Synthesized by Citrate Gel Method

World Journal of Condensed Matter Physics 2012年第2期2卷 57-60页

College of Science Osmania University Hyderabad India

Ni-Zn ferrite with composition of Ni1-xZnxFe2O4 (x = 0.0, 0.2, 0.4, 0.6, 0.8, 0.9, 1.0) were prepared by citrate gel method. The Dielectric Properties for all the samples were investigated at room temperature as a function of frequency. The dielectric constant shows dispersion in the lower frequency region and remains almost constant at higher frequencies. The frequency dependence of dielectric loss tangent (tan δ) is found to be abnormal, giving a peak at certain frequency for mixed Ni-Zn ferrites. A qualitative explanation is given for the composition and frequency dependence of the dielectric loss tangent.

Seasonal Variation of Urban Heat Island and Its Impact on Air-Quality Using SAFAR Observations at Delhi, India

引用

American Journal of Climate Change 2017年第2期6卷 294-305页

作者： M. Y. Aslam K. rama krishna G. Beig M. I. R. Tinmaker D. M. Chate Indian Institute of Tropical Meteorology Pune India

This paper discussed the urban heat island (UHI) intensity and local air quality by using observational data of project of the System of Air Quality Forecasting and Research (SAFAR) over Delhi during the month of May and December 2013. It is found that UHI magnitudes ~2.2°C and ~1.5°C are formed at the evening traffic hours during May and December respectively. Also, intensity of UHI °C over daytime is referred as Urban Cool Island (UCI) during May and December. The diurnal PM2.5 concentration shows a bimodal pattern with peaks at morning and evening traffic hours during May and December. The planetary boundary layer height (PBLH) values show higher in magnitude during the daytime and lower in magnitude during the night-time. Whereas, the Ground Heat Flux values are lower during the daytime and higher during the night-time. The wind speed shows lower values during the UHI and higher magnitudes during the UCI formation hours. Concentration of PM2.5 and wind speed shows a strong negative correlation during May (r = -0.56, p = 0.002) and December (r = -0.57, p = 0.001) at C V raman (CVR) site, however, high values in the concentration of PM2.5 during the low wind speed favour the condition for the formation of UCI. The regression analysis indicated that PM2.5 plays a significant role in the daytime cooling and nighttime warming over the urban areas during the low wind speed condition.

背景：膝关节置换术中某些外科医生在关闭切口前松止血带以达到止血的目的。我们通过对随机对照研究的荟萃分析法观察关闭切口前松止血带是否会减少围手术期失血，及关闭切口后再松止血带是否会增加术后早期并发症的风险。方法：检索电子数据库及相关文献的参考目录，搜集到所有已发表的用于论证这些问题的随机对照试验，进行荟萃分析。结果：对涉及872例893膝初次膝关节置换患者的11项研究进行系统分析。这些研究具有显著的临床和方法学上的多样性。早松止血带增加了总出血量（加权均数差=228．7ml；95％可信区间为168．3-289．1；p〈0．00001）。通过血红蛋白浓度最大丢失量的计算也提示早松止血带增加失血量（加权均数差=320．7ml；95％可信区间为204．3-4．37．1；p〈0．00001）。术后并发症须再手术率在迟松止血带组为3．1％（9／290），而在早松止血带组则为0．3％（1／290）；两者风险差距为3％（95％可信区间为0．1-5％），差异有统计学意义（p=0．04）。结论：关闭切口前松止血带增加了初次膝关节置换术中的失血量，而关闭切口后松止血带增加了致再次手术的早期并发症的发生风险，为进一步揭示膝关节置换术后发生与迟松止血带相关早期并发症的风险仍须进行大量的优质研究。

关键词：膝关节置换术随机对照研究荟萃分析止血带术后早期并发症发生风险随机对照试验可信区间
