Renewable energy often referred to as clean energy, is an important energy source that comes from natural sources or processes that are constantly replenished such as solar, wind, geothermal and hydro-based energy. Zambia’s installed energy capacity stands at 2,800 Megawatts (MW) of which 85...

This study aims to obtain a lower bound on the eigenvalue of the smallest modulus in a general weighted regular Sturm-Liouville problem with mixed boundary conditions. The problem is expressed as -u′′(x) + q(x)u(x) = λr(x)u(x) over the interval [a,b] with u′(a) = u(b) = 0. In 1988 Mingarelli [31]...

Effective agricultural monitoring is essential for ensuring food security and efficient resource management. This study aimed to use Synthetic Aperture Radar (SAR) from Sentinel 1 and Optical imagery from Sentinel 2 multi spectral instrument (MSI) for mapping and monitoring Maize fields in the...

The optical investigation of tungsten diphosphide (WP2), a type-II Weyl semimetal, reveals its exceptional topological and anisotropic electronic properties. Through resistivity and Fourier-transform infrared spectroscopy measurements, WP2 exhibit high conductivity and anisotropic transport...

Initial Teacher Education is designed to prepare pre-service teachers for teaching and to establish a foundation for continuing professional development (CPD). The objectives of this qualitative case study research were to: establish mathematics preservice student teachers’ conceptions of CPD;...

In the last three decades, there has been a growing interest on how teachers utilise the specialised knowledge for mathematical knowledge in classroom instruction. This study was an inquiry focusing on mathematical knowledge for teaching quadratic equations. The study was a qualitative and sought...

Climate change is altering hydrological patterns, leading to extreme weather events such as prolonged droughts, intense floods, and shifts in precipitation patterns threatening water supply systems in the Barotse Floodplain. This has adversely affected the rural communities in the Barotse...

The purpose of the study was to investigate the long-term sustainability of lesson study in teaching and learning mathematics in selected schools in Lusaka district, Zambia. The study utilized a qualitative case study and was based on social constructivism. Six purposively selected teachers of...

This study investigated the biomagnification impact of elevated iron levels in mine effluent on human health around Nampundwe Mine area in Shibuyunji District of Zambia. Nampundwe Mine produces massive Pyrite (FeS2) with minor Pyrrhotite (FeS) and chalcopyrite (CuFeS2) used in copper smelters....

Carbon trading has emerged as a leading solution to reduce greenhouse gas emissions, combat climate change, and deliver significant environmental, economic and social benefits for communities in developing countries. However, there are concerns about how it is being implemented and whether it is...
