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...

A collection of computers linked together through a communication channel are known as a computer network. Such a network facilitates communication and resource sharing between netwo rks. The linkages are facilitated by data transmission lines, which can be optical or Ethernet cables . The data...

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...

The Zambian construction industry is comprised of more than 90 percent small and medium enterprise (SME) contractors who are faced with a myriad of constraints that affect their performance with regards to quality, cost and timely delivery of projects. The research was aimed at establishing ways...

The management of Zambia’s national strategic food reserve is done by the Food Reserve Agency (FRA), which also ensures that the country’s food market is well facilitated. The FRA also ensures that there is a reliable supply of agricultural commodities to meet local shortfalls during food...
