| 1 | Tuberculosis infection prevention and control:why we need a whole systems approach显示文摘Infection prevention and control(IPC)measures to reduce transmission of drug-resistant and drug-sensitive tuberculosis(TB)in health facilities are well described but poorly implemented.The implementation of TB IPC has been assessed primarily through quantitative and structured approaches that treat administrative,environmental,and personal protective measures as discrete entities.We present an on-going project entitled Umoya omuhle(“good air”),conducted in two provinces of South Africa,that adopts an interdisciplinary,‘whole systems’approach to problem analysis and intervention development for reducing nosocomial transmission of Mycobacterium tuberculosis(Mtb)through improved IPC.We suggest that TB IPC represents a complex intervention that is delivered within a dynamic context shaped by policy guidelines,health facility space,infrastructure,organisation of care,and management culture.Methods drawn from epidemiology,anthropology,and health policy and systems research enable rich contextual analysis of how nosocomial Mtb transmission occurs,as well as opportunities to address the problem holistically.A‘whole systems’approach can identify leverage points within the health facility infrastructure and organisation of care that can inform the design of interventions to reduce the risk of nosocomial Mtb transmission. | Karina Kielmann Aaron S.Karat Gimenne Zwama Christopher Colvin Alison Swartz Anna S.Voce Tom A.Yates Hayley MacGregor Nicky McCreesh Idriss Kallon Anna Vassall Indira Govender Janet Seeley Alison D.Grant | 2020 | Infectious Diseases of Poverty2020，9，3： | 1 |
| 2 | 乳基白炭黑母炼胶的制备工艺显示文摘开发出一种白炭黑母炼胶生产工艺。这种工艺可以使白炭黑/硅烷配比以及疏水白炭黑/聚合物/填充油配比得以非常严格的控制,这对白炭黑母炼胶在轮胎工厂的成功应用是至关重要的。这种白炭黑母炼胶可以取代传统的白炭黑混炼胶,总混炼时间大大减少,轮胎性能相当。基于该独特的湿法混炼白炭黑母炼胶工艺实现了白炭黑的高度分散,显然可利用这种白炭黑母炼胶技术来提高轮胎的性能。 | 朱永康 Howard Colvin Christopher Hardiman | 2015 | 现代橡胶技术2015，41，2： | 1 |
| 3 | African Cassava Whitefly,Bemisia tabaci,Resistance in African and South American Cassava Genotypes显示文摘The whitefly,Bemisia tabaci,is a major pest of cassava,particularly in Africa where it is responsible both for the transmission of plant viruses and,increasingly,for direct damage due to feeding by high populations.To date,there have been no practical solutions to combat this emerging problem,due to the inability of the subsistence farmers that grow cassava to afford expensive inputs such as insecticides.A programme of research was carried out linking institutes in Africa,the UK and South America,to identify possible resistance sources in cassava to the whitefly,Bemisia tabaci.The South American genotype MEcu 72 and several Ugandan cassava landraces including Ofumba Chai,Nabwire 1 and Mercury showed good levels of resistance to B.tabaci.Field and screen-house experiments showed that all of the improved,high-yielding cassava mosaic disease(CMD)resistant cassava genotypes assessed were highly susceptible to B.tabaci and supported high populations of all life stages.These data support the hypothesis that the continuing high populations of cassava B.tabaci in Uganda are due,in part,to the widespread adoption of CMD-resistant cassava varieties during the CMD pandemic.They also show that the whitefly,Aleurotrachelus socialis,resistance present in the South American cassava genotypes could have broader applicability in the Old World. | Christopher A Omongo Robert Kawuki Antony C Bellotti Titus Alicai Yona Baguma M N Maruthi Anton Bua John Colvin | 2012 | Journal of Integrative Agriculture2012，11，2： | 0 |
