The COVID-19 pandemic is the biggest public health and economic challenge the world has faced for the past three years. Since there was no vaccine during the early phase of the pandemic, Botswana imposed lockdown as one of the non-pharmaceutical interventions to mitigate the COVID-19 burden....

Making cities champions of climate mitigation and adaptation requires the downscaling of policies and instruments to local and city levels. The Zambia National Climate Change Policy in City Development Plans(NPCC) was designed for incorporation into the Lusaka City Council Development Plans for...

Wetlands are essential for the natural function of ecosystems, because they regulate floods and have many other significant functions. However, land use-land cover (LULC) changes are the main drivers of wetland deterioration globally, and Zambia is no exception. This study examined LULC changes...

This study aimed to determine the maximum likelihood (ML) estimates for the Gamma and Exponential distributions under conditions of left-truncated and right-censored data, employing the Expectation-Maximisation (EM) algorithm. Additionally, it sought to compare the performance of the EM algorithm...

The objective of the study was to assess the regeneration of Miombo woodlands after shifting cultivation in Chibombo and Rufunsa districts in comparison to undisturbed woodland. The study analysed different descriptors that characterize the woodland including: species composition, diversity,...

This dissertation is devoted to the investigation of the optical properties of two topological insulators, Bismuth Selenide (Bi2Se3) and Antimony Telluride (Sb2Te3), by optical spectroscopy reflection measurements in a wide frequency range (500 – 40000 cm−1 ) and temperature (13 to 300 K) ....

Advancement in internet technology allows for the integration of network traffic i.e data, video and voice into a single network. This technology offers many benefits but also presents some challenges. Real time traffic services such as Voice over Internet Protocol (VoIP) and video require...

For nearly two (2) decades, Multiprotocol Label Switching (MPLS) has provided Wide Area Network (WAN) solutions for enterprises and large organizations to manage their multiple networks in different locations. Real time networks have been affected negatively by high latency due to inefficient WAN...

In this dissertation we obtain quasi-deformations of the special linear Lie algebra of degree 2 over a eld F, abbreviated sl2(F). We take F to be a eld of characteristic zero. Our approach involves obtaining and deforming a linear operator representation of sl2(F) using-twisted derivations (with...

Endocrine disrupting compounds (EDCs) are receiving increased attention in the environment due to their link to lifestyles diseases like hypertension, heart disease, type 2 diabetes and some cancers. This research aimed at assessing the presence and quantities of heavy metals and organic EDCs in...
