| 3 | Improving the surveillance and response system to achieve and maintain malaria elimination:a retrospective analysis in Jiangsu Province,China显示文摘Background:Following initiation of China’s National Malaria Elimination Action Plan(NMEAP)in 2010,the'1-3-7’approach was developed and rolled out in China to facilitate the malaria elimination programme and accelerate malaria elimination.This study aims to summarize and condense these experiences through a retrospective analysis in Jiangsu Province,which could be adapted and applied in other malaria elimination settings worldwide.Methods:A retrospective analysis of imported malaria cases into China identified through an improved surveillance and response system in Jiangsu Province was carried out for the period of 2001-2020.To improve the malaria surveillance and response system,Centers for Diseases Control and Prevention from the prefectures and counties in Jiangsu province conducted population-level health education to improve healthcare seeking behavior,strengthened capacity of health facilities to improve performance of malaria diagnosis and treatment,and raised the capacity of public health providers to improve implementation of the'1-3-7’approach.Categorical variables were carried out by Chi square tests with Fisher’s exact correction.Results:From 2001 to 2020,a total of 9,879 malaria cases were reported in Jiangsu Province.Since 2012,no indigenous malaria cases have been reported in Jiangsu Province.However,in recent years,there has been a substantial increase of imported falciparum malaria cases.Between 2012 and 2020,an estimated 61.57 million individuals have benefited from population-level health education in Jiangsu Province.For healthcare-seeking services among the 2,423 imported malaria cases,687(28.4%)and 1,104(45.6%)cases visited hospitals on the first day and the second day from symptom onset,respectively.A total of 1,502(61.9%)cases were diagnosed on the first day at medical facilities.Jiangsu Province achieved 100%,99.4%and 98.3%completion rate in terms of case detection and notification(within one day),case investigation(within three days)and foci response and disposition(within seven days),respectively.The improved surveillance and response system in Jiangsu Province plays an important role in preventing the re-introduction of malaria and maintaining the malaria-free status.Conclusions:Jiangsu Province has maintained its malaria-free status since 2012.The continuous improvement of a surveillance and response system plays an important role in the early detection and rapid response of potential malaria-related outbreaks in Jiangsu,China,and has important lessons for other malaria eliminating settings.Remaining vigilant in the detection of imported malaria cases and maintaining an active surveillance and response system is critical to sustain the success of malaria elimination. | Yuanyuan Cao Guangyu Lu Chris Cotter Weiming Wang Mengmeng Yang Yaobao Liu Cheng Liang Huayun Zhou Yan Lu Jun Yan Guoding Zhu Jun Cao | 2022 | Infectious Diseases of Poverty2022,11,1: | 1 |

| 5 | Analysis of oil shedding and ligaments formation on bearing rotary elements显示文摘For designing efficient lubrication system of an aeroengine bearing chamber,sufficient knowledge on oil/air two-phase flow characteristics is required.When analyzing bearing chamber two-phase flow,the essential prerequisite is quantifying the oil ligaments,which are detached from bearing rotary elements and shed into the bearing chamber.Related investigations are mainly targeted at liquid shedding on the rotating disk as opposed to the bearing rotary elements.Moreover,the research based on bearing rotary elements is conducted by experiment.Due to the limited operating conditions,experimental studies cannot guide engineering applications.To overcome these limitations,a theoretical model is established in this paper,for revealing the mechanism of oil shedding from bearing rotary elements and quantifying the shedding ligaments.The theoretical model is validated against experimental results from classical studies.In addition,the correlation for shedding ligaments number based on aeroengine bearing structural and operational parameters is obtained via theoretical analysis.The analytical results demonstrate that oil shedding and ligaments formation appear at the edge of bearing inner race outer-periphery.The number of shedding ligaments increases with the rise of shaft rotational speed while decreases with the growth of oil viscosity. | Donglei ZHU Guoding CHEN Yanjun LI Chaoyang ZHANG Lin WANG | 2023 | Chinese Journal of Aeronautics2023,36,2: | 0 |
| 6 | A 3D CFD simulation of oil spray-collection and delivery process in an aeroengine inter-shaft bearing显示文摘Under-race lubrication applied to the inter-shaft bearing of aeroengine is characterized by spray oil collection and oil delivery to the bearing via flow-path structure. Droplet splashing induced by the collision between spray oil and the scoop as well as oil flowing characteristics in the flow-path influence bearing lubrication efficiency. In previous investigations, the spray oil collection and oil delivery analysis were separated, and the effect of droplet splashing on bearing lubrication efficiency was not considered. Moreover, time-varying characteristics of oil delivered to the bearing were not accounted for. This is caused by time variations of the circumferential position of rollers and under-race feed holes. To overcome these limitations, a numerical model which integrates the spray oil collection and oil delivery analysis is proposed in this paper. The model is embedded with the function of calculating the flow rate of splashing droplets and analyzing time-varying characteristics of the oil fed to the bearing. Furthermore, the numerical model is validated by experimental investigation. The proposed numerical model facilitates the accurate calculation of bearing lubrication efficiency as well as the design of an efficient lubrication structure. | Donglei ZHU Guoding CHEN Yanjun LI Chaoyang ZHANG Lin WANG | 2022 | Chinese Journal of Aeronautics2022,35,9: | 0 |
