Konkola Mine is one of the wettest mines in the world. It pumps about 350,000m3 of water per day. From the inception of mining operations in 1956, water has always posed a challenge to mining despite the use of dewatering strategy involving dewatering crosscuts and dewatering boreholes. The...

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%...

Cassava is one of the alternative crops to Zambia’s staple crop maize. Unlike maize, cassava is drought resistant; maize has adversely been affected by drought. Unfortunately cassava has been ravaged by the African cassava mosaic virus for over one hundred years. It causes cassava mosaic disease...

Diabetic retinopathy (DR) is a common microvascular complication of diabetes mellitus and also a leading cause of visual impairment among people in the working age group. Retinopathy develops overtime in all diabetics and controlling the modifiable risk factors delays its onset and progression....

The contemporary smooth structures that describe the motion of particles on underlying sets through the related specified differential geometry need to be assessed in the sense of stabilising the advantage of working with one or another. Such a study is what we call a comparative smootheology. A...

In Zambia, many smallholder farmers achieve household food security through the production of maize ‘zea mays’. During the years of maize failure due to drought, there is need for other crops to enhance food security like Orange Fleshed Sweet Potato. Since the 2010/2011 farming season, the Orange...

Zambia has been experiencing adverse impacts of climate change. Generation of climate information about changes in future precipitation and temperature is useful in designing adaptive measures. Currently, global climate models (GCMs) are primary tools utilized to simulate the present and future...
