We are glad to present the 34th volume of International Journal of Engineering Research in Africa to our readers. This volume contains articles describing the research results in the fields of materials science in the mechanical engineering, construction materials, technological processes in the chemical production, power distribution, communication engineering and engineering management. The articles will be useful for many engineers as well as for academic teachers and students majoring in these fields of engineering science.

The 69th volume of the journal includes articles dedicated to the latest research results in properties and processing technologies of structural materials such as steel, polymers, and composites, analysis and design of sliding mode controllers and automation of centrifugal pumps, designing of geothermal heat exchangers, investigation of seismic behaviour of soil-based structure and analysis mechanics of river's sediments transfer in conditions of Wadi Skhirate, Morocco. The issue will be useful to specialists in mechanical engineering and construction.

This journal volume contains papers that reflect research results in materials science, power engineering, and environmental engineering. Additionally, under the focus of this volume is the study on reducing wastes formation in the construction industry. Furthermore, the presented research results may find useful for scientists and engineers deal with powder metallurgy issues and material characterization. Some papers are devoted to solving drilling issues in the oil and gas industry. Eventually, the volume presents an analysis of various algorithms that can find their application in civil and industrial engineering areas.

This periodical edition includes peer-reviewed papers based on results of scientific research and engineering solutions in different areas of modern engineering science.
