Zambia and Ethiopia are two countries from southern and eastern of Africa due to their geographical location and other factor the environment condition is different. The research aims to Investigation how operational and climatic factor affect PV-grid tied inverter. In Zambia the study focused on...

Excreta ought not to be viewed solely as a problem but as a potential resource from which valuable resources can be obtained and sold to consumers. One of the resources that can be recovered from faecal sludge is briquettes. Briquettes can be processed from faecal sludge and used as a sustainable...

Stabilization and dewatering are indispensable treatment mechanisms applied in the management of Faecal Sludge (FS) that accumulates in onsite containment facilities such as pit latrines and septic tanks. This is because FS is mainly comprised of 80 – 95 percent water and readily degradable...

The motivation for venturing in alternative jet fuels has partly been due to the elevated level and volatility of the price of Jet A (a kerosene-based aviation gas turbine fuel) and environmental impacts on global climate change and air quality. The model of the annular combustor for the PT6A-27...

In recent years, the world is gradually shifting away from the use of structural concrete in the construction sector. This is due to its retrogressive limitations such as costs, environmental degradation, low strength-to-weight ratio, its susceptibility to cracking. The world is moving towards...

The study aimed at demonstrating the positive outcome of incorporating optimization techniques in the design procedure for designing steel-concrete composite bridges was conducted. Optimization algorithms have the capability of finding optimal or near optimal solutions in complex problems. In...

In practice, cured concrete strength may exhibit strength variation from batch to batch and within batch despite the mixes being of the same proportions and with quality control. On the other hand, structural concrete elements are designed to meet specific characteristic strength. In order to...

The rapid adoption of electronic channels for the delivery of services by various service providers compels the consumers of these services to adapt. For one to be granted access to e-services, one must surrender part of their Personally Identifiable Information (PII) hence making their personal...

Building Construction in Zambia has been booming at a faster rate than ever before. Local authorities have had the challenge of pacing up in quality control with these fast developments. The integrity of built infrastructure in a city guarantees safety of occupants, minimises maintenance costs to...
