Conclusions:Using these baseline data would be useful in planning for the elimination of lymphatic filariasis in Andhra Pradesh as per the WHO goal to eliminate lymphatic filariasis by 2020.展开更多

Similarly,MIR fluctuated between seasons with higher MIR recorded after monsoon period and lower in the rest of season.Impact of these metrological parameters in JE virus infected mosquitoes is discussed in this paper.展开更多
A series of CeO2-Al2O3, CeO2-TiO2, CeO2-ZrO2, and CeO2-SiO2 mixed-oxide supported copper catalysts were prepared by a modified deposition-precipitation method from ultra dilute aqueous solutions and were investigated ...A series of CeO2-Al2O3, CeO2-TiO2, CeO2-ZrO2, and CeO2-SiO2 mixed-oxide supported copper catalysts were prepared by a modified deposition-precipitation method from ultra dilute aqueous solutions and were investigated for hydrogenolysis of cellulose in aqueous medium, in the presence of hydrogen to produce sorbitol as major product. Among all the catalysts tested in the present work, CuO/CeO2ZrO2?catalyst proved to be the most promising with high conversion (92%) and excellent selectivity (sorbitol 99.1%), at an intermediate reaction temperature of 245°C in a neutral aqueous solution without an aid of liquid phase acid. The catalyst was recyclable in repeated runs and no deactivation was observed even after five reaction cycles. CuO/CeO2-ZrO2 has been characterized by XRD, SEM, TPR and BET surface area techniques.展开更多
