Problem India and sub-Saharan Africa contributes about 85% of the global malaria burden, and India is committed to eliminating malaria by 2030. Approach Two novel initiatives—the Malaria Elimination Demonstration Project (MEDP) in Madhya Pradesh and Durgama Anchalare Malaria Nirakaran (DAMaN) in Odisha—were initiated independently to demonstrate that indigenous malaria can be eliminated in a short period of time. Local setting These initiatives focused on rural, tribal areas where there is a high malaria burden and complex epidemiology. Relevant changes The case management and vector control strategies used in these programmes were based on the national guidelines, with context-specific changes and introduction of accountability at management, operational, technical and financial levels. The MEDP achieved a 91% reduction in malaria cases and recorded zero transmission for 6 consecutive and a total of 9 mo. The DAMaN project brought about an 88% reduction in malaria cases. Lessons learned Malaria elimination will require robust surveillance and case management, monitoring of vector control interventions, community-centric information education communication and behaviour change communication initiatives and management controls, as well as regular internal and external reviews.
Viscosities (η) and densities (ρ) of five binary mixtures of ethanenitrile with benzene and several substituted benzenes viz methylbenzene, 1,4-dimethylbenzene, chlorobenzene and 1,2-dichlorobenzene have been experimentally determined at 308.15 K. Viscosity deviations (∆η) from the linear blending rule have been evaluated for all the mixtures studied. These are small with a maximum negative deviation of about 6% for binary mixture with benzene and maximum positive deviation of about 3% for mixture with 1,4-dimethylbenzene. ∆η Values are fitted into RedlichKister equation and standard deviations in ∆η values, σ (∆η) have been evaluated. The correlating performance of several viscosity models such as Grunberg -Nissan, Katti and Chaudhari, Hind-McLaughlin -Ubbelohde and Sedgwick has been evaluated. Grunberg-Nissan viscosity model is suitable for viscosities of several binary systems studied. The results are discussed in terms of molecular interactions between the components of binary mixtures.
Globalization has adversely affected development of rural areas in developing countries. Rural areas are unable to absorb new technologies due to low literacy rates. Local Products, mostly from agricultural produces, are increasingly replaced by cheaper products from organized mechanized farming from one or the other corner of the globe. In this paper, family type cabinet solar dryer designs are presented in commensuration with the contemporary requirement of rural Bihar. Design objective includes simplification of technology and process, easy maintenance and low price to dry exotic produces which has significant export potential. Field trials are conducted, social surveys are undertaken and nutritional values of the products are determined in actual condition. Results indicate that simpler technology with state-of-art control of temperature by a combination of high heat capacity material and phase change material is most suitable to dry vegetables and spices, commonly called "Cash Crops". Their nutritional values remain within 80% limits even after six months. The technology is appropriate as it uses local materials; sustainable as it is cost-effective and employment generating ability and; robust as it uses very simple way for controlled drying.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
