Mini hydropower plays a critical role in providing energy access to remote areas through mini grids. However, the development of mini hydropower sites has lagged in Zambia with the country only witnessing the construction of two off-grid mini hydropower stations namely, Zengamina and Shiwan’gandu...

The uptake of Public – Private Partnerships (PPPs) in the road sector in Zambia has been limited, despite the government of the Republic of Zambia’s initiatives as far back as 2009 when the PPP Act was enacted. This study sought to find out the main challenges in the implementation process and to...

Crime solving comprises methodical law enforcement, an exhaustive investigation and collection of facts, and extensive evidence testing performed by criminalists and forensic experts. All the efforts might be in vein if the evidential items collected from the crime scene are not handled in a...

If the construction industry of a country is inefficient, it is difficult for any such country to see meaningful development. This is particularly true for countries that often see many of its projects abandoned. Globally projects continue to be abandoned. In Zambia, the number of projects being...

In the determination of an improved geoid over Zambia, the Modified Stokes’ formula employing the RCR technique was used. The formula combined EGM2008 data, terrestrial classical free-air gravity anomalies over Zambia, and the SRTM 3′′ DEM over Zambia which represent the long, intermediate, and...

Soil plaster pastes have been used around the world by local rural populations for centuries to give a finishing touch to their houses, and depending on the soil used, some chemical contamination cannot be ruled out. Some soils may contain heavy metals and other parameters depending on where it...

Zambia’s transport sector is driven by imported and costly fossil fuels. Apart from the cost element, fossil fuels are finite. The source is depleting as it is being extracted continuously. Fossil fuels are also pollutants to environment. They contribute 70% of global carbon monoxide (CO) and 19%...

Public Private Partnerships have become an alternative contract model for government infrastructure. Construction and management of public markets has not been left out in this shift. Public markets come with several benefits, some of which include creating additional tax base with minimal local...

In machining operations, the effects of high temperatures are i) reduction in tool life, ii) production of hot chips and iii) inaccuracies in workpiece dimensions. Coolant is applied to convey away heat to extend tool life and ensure a good surface finish of the workpiece. While conventional...
