| 1 | 导电性对纳米磁流体后向混合对流的影响(英文)显示文摘本文对纳米磁流体的几种电导率模型进行了数值模拟,研究了Al2O3-水纳米磁流体后向流动的混合对流效应。对流体施加均匀的外部磁场时,通过改变无量纲参数Hartmann数(Ha=0,10,20,30,40)实现磁场强度的变化。应用3种不同的电导率模型监测纳米磁流体的流动。同时,在研究过程中还选取了0°~90°范围内的5中倾角下的外部磁场。后向流动常用于求解流体分流和再合流现象的工程问题。根据不同电导率模型,采用不同的Richardson数(Ri=0.01,0.1,1,10)和4种不同的纳米粒子体积分数(Ф=0.01,0.015,0.02,0.025),对混合型后向流的对流换热进行研究。采用商业代码COMSOL有限元方法进行计算。结果表明,添加纳米颗粒增强了传热效果,增加磁场强度和倾角也增加了热传递速率。在对流体流动施加外部磁场的情况下,不同电导率模型对流体的流动和传热效果也有不同的影响。 | SELIMEFENDIGIL Fatih OCAN CBAN Seda OTOP Hakan F. | 2019 | Journal of Central South University2019，26，5： | 4 |

| 13 | Household perceptions and subjective valuations of indoor residual spraying programmes to control malaria in northern Uganda显示文摘Background:Insecticide-based tools remain critical for controlling vector-borne diseases in Uganda.Securing public support from targeted populations for such tools is an important component in sustaining their long-run effectiveness.Yet little quantitative evidence is available on the perceived benefits and costs of vector control programmes among targeted households.Methods:A survey was administered to a clustered random sample of 612 households in Gulu and Oyam districts of northern Uganda during a period of very high malaria transmission and following a pilot indoor residual spray(IRS)programme.A discrete choice experiment was conducted within the survey,in which respondents indicated their preferences for different IRS programmes relative to money compensation in a series of experimentally controlled,hypothetical choice sets.The data were analysed using conditional logit regression models to estimate respondents’willingness to accept(WTA)some amount of money compensation in lieu of foregone malaria risk reductions.Latent class models were used to analyse whether respondent characteristics predicted WTA.Results:Average WTA is estimated at$8.94 annually for a 10%reduction in malaria risk,and additional co-benefits of IRS were estimated to be worth on average$54–$56(depending on insecticide type)per round of IRS.Significant heterogeneity is observed:Four in five household heads in northern Uganda have high valuations for IRS programmes,while the remaining 20%experience costly side effects of IRS(valued at between$2 and$3 per round).Statistically significant predictors of belonging to the high-value group include respondent gender,mean age of household members,participation in previous IRS,basic knowledge of mosquito reproduction,and the number of mosquito nets owned.Proxies for household income and wealth are not found to be statistically significant predictors of WTA.Conclusions:This study suggests that the majority of people in areas of high malaria transmission like northern Uganda place a high value on vector control programmes using IRS.However,there is significant heterogeneity in terms of the perceived side effects(positive and negative).This has implications for sustaining public support for these programmes in the long-term. | Zachary S.Brown Randall A.Kramer David Ocan Christine Oryema | 2016 | Infectious Diseases of Poverty2016，5，1： | 0 |
