Rice cultivation in Sub-Saharan Africa produces a negative externality in the form of higher malaria risk. Larval source management, such as the application of bio-larvicides in rice fields, is available to mitigate the problem. However, the cost of larvicide and the corresponding spraying...

The threat from dengue has grown dramatically. The World Health Organization estimates that there may be up to 100 million infections each year worldwide. Approximately 500,000 people are hospitalized, and many thousands die because of dengue each year. Controlling mosquitoes is the only...

This paper discusses implementation of the Fifth National Development Plan (FNDP) in Zambia. The planning process of the FNDP integrated views from the Provincial and District Development Plans approved by the respective provincial and district level organs. The FNDP’s goals are...

The large-scale application of doubly-fed wind turbines has significantly changed the fault transient characteristics of power systems. However, the transient state of a doubly-fed induction generator (DFIG) under large disturbances is difficult to accurately evaluate. The main difficulty lies...

Variable frequency drives (VFDs) can provide reliable dynamic systems and significant savings in energy usage and costs of the induction motors (IMs). Sensorless controlled IM drives have advantages in terms of efficiency enhancement and energy savings for critical applications such as electric...

Effective participatory strategies in dengue control have been developed and assessed as small-scale efforts. The challenge is to scale-up and institutionalize these strategies within dengue control programs. We describe and critically analyze the diffusion process of an effective empowerment...
