A mathematical modelling approach for the elimination of malaria in Mpumalanga, South Africa
… to predict impact without committing any real resources. Three models are developed to simulate malaria transmission: (1) a deterministic non-linear ordinary differential equation model, (2) a stochastic non-linear metapopulation differential equation model and (3) a stochastic hybrid …

Freirean Codes: A Transformative Educational Tool for Community Empowerment and Arboviral Control in Kenya
… There is a lack of awareness about proper source reduction and mosquito life cycle; perceived importance of covering drinking water and keeping it free from insects but not water used for other purposes. Also, a huge misconception about disease transmission exists. People are more concerned …

Use of a textile wastewater sludge as a supplemental solid fuel
… laboratory testing helped to locate major sources of these elements within the plant. The concentrations of these metals in the final by-product are expected to be reduced to some extent by future source-reduction efforts. It is recommended that the information contained in this report be …
