Faculty of Sciences
Browse by
The Faculty of Sciences (FoS), is one of the recently established faculties in Botswana University of Agriculture and Natural Resources (BUAN). The mandate of the faculty is to advance the BUAN’s mission of ‘producing market-ready graduates for the agriculture and natural resources sectors’. The Faculty will achieve this by laying a solid foundation of sciences for all the University’s science based academic programmes and developing and offering relevant science based programmes. Structurally the Faculty has three (3) departments namely Biological Sciences (BS), Biometry and Mathematics (BM) and Physical and Chemical Sciences (PCS).

The variability and predictability of the IRI B 0 , B 1 parameters over Grahamstown, South Africa
(COSPAR Committee on Space Research, 2009-09-15)The International Reference Ionosphere (IRI) parameters B0 and B1 provide a representation of the thickness and shape, respectively, of the F2 layer of the bottomside ionosphere. These parameters can be derived from electron ... -
Implementation of a boundary element method for high frequency scattering by convex polygons with impedance boundary conditions
(SCImago, 2016)Many acoustic and electromagnetic wave scattering problems can be formulated as the Helmholtz equation. Standard finite and boundary element method solution of these problems becomes expensive, as the frequency of incident ... -
Effect of hollow centre post in coupled combline resonators
(IEE Explore, 2017)The effect of thickness of a hollow post in a combline resonator on the resonant frequency, coupling coefficients and spurious performance are analysed. It is shown that both the electric and magnetic couplings are not ... -
Understanding the Impacts of Rainfall Variability on Natural Forage–Livestock Dynamics in Arid and Semi-Arid Environment
(MDPI, 2025)Arid and semi-arid environments are characterized by highly variable and unpredictable rainfall patterns, which significantly affect the structure and function of natural ecosystems. Understanding the interconnected ... -
Determinants of participation in charcoal production and its distributive impact on household welfare in rural Ethiopia
(Elservier, 2024-10-24)Charcoal production is one of the main sources of households’ income in some part of rural Ethiopia. However, existing literature has rarely explored the presence of an entry barrier that might prevent the poorest from ... -
Modeling the Effect of HIV/AIDS Stigma on HIV Infection Dynamics in Kenya
(Springer, 2021)Stigma toward people living with HIV/AIDS (PLWHA) has impeded the response to the disease across the world. Widespread stigma leads to poor adherence of preventative measures while also causing PLWHA to avoid testing and ... -
Mathematical models for the dynamics of alcohol related health risks with changing behavior via cultural beliefs in tanzania
(SCIK Publishing Corporation, 2020)Alcoholism has continually posed health challenges in many communities for decades. In this paper, a more realistic model for health related risks associated with alcoholism is formulated. It considers a population proportion ... -
Modeling and evaluating targeted interventions to curb avian influenza spread among humans and domestic birds
(SCIK Publishing Corporation, 2026)Avian influenza, caused by influenza A viruses, has drawn substantial attention globally due to increased deaths from time to time. This study examines control interventions for avian influenza transmission in humans and ... -
Modeling the effects of contaminated environments on the transmission dynamics of avian influenza in humans and domestic birds
(Elservier, 2025-09)Avian influenza is a viral infection that affects birds and can spread to humans and other animals, causing severe illness and high mortality in both populations. Migratory birds are the primary transmitters of the virus, ... -
Coffee farmers’ perception of climate change trends in Gimbi district, Western Ethiopia
(Springer Nature, 2024-12)Climate change and variability pose substantial threats to rain-fed agriculture, critically impacting the livelihoods of rural communities in Ethiopia. The Gimbi District, recognized for its high agricultural potential ... -
Modeling salmonellosis transmission dynamics in humans and dairy cattle with optimal controls.
(Elsevier Inc., 2025-02)In this paper, we develop a mathematical model to examine the transmission dynamics and control analysis of salmonellosis in humans and dairy cattle. The model considers three time-dependent controls (improving hygiene, ... -
Dynamical modeling of Salmonellosis in humans and dairy cattle with temperature and pH effects.
(Elsevier B.V., 2024-12-20)Approximately 20 million cases and 0.15 million human fatalities worldwide each year are caused by Salmonellosis. A mechanistic compartmental model based on ordinary differential equations is proposed to evaluate the effects ... -
Wind dispersed tree species have greater maximum height.
(John Wiley and Sons Inc, 2024-06-14)Aim: We test the hypothesis that wind dispersal is more common among emergent tree species given that being tall increases the likelihood of effective seed dispersal. Location: Americas, Africa and the Asia-Pacific. Time ... -
Analyses of LULC dynamics in a socio-ecological system of the Bale Mountains Eco Region of Southeast Ethiopia.
(Springer Science and Business Media Deutschland GmbH, 2024-06-21)Analysis of land use and land cover (LULC) change and its drivers and impacts in the biodiversity hotspot of Bale Mountain’s socio-ecological system is crucial for formulating plausible policies and strategies that can ... -
Smallholder agriculture in African dryland agroecosystems has limited impact on trophic group composition, but affects arthropod provision of ecosystem services.
(Elsevier B.V., 2024-04-01)Agricultural intensification is a major driver of biodiversity loss, but the majority of studies highlighting these threats come from industrialised agriculture in temperate countries of the global North. However, more ... -
Enteric methane emission factors of smallholder dairy farming systems across intensification gradients in the central highlands of Ethiopia.
(BioMed Central Ltd, 2023-11-29)Background: Following global pledges to reduce greenhouse gas (GHG) emissions by 30% by 2030 compared to the baseline level of 2020, improved quantification of GHG emissions from developing countries has become crucial. ... -
Quadratic sequences in Pythagorean triples
(American Institute of Physics, 2022-06-16)Using the Euclid's formula, we obtain an alternative formula for generating Pythagorean triples, both primitive and non-primitive. It easy to classify Pythagorean triples using this formula based on the divisibility of the ... -
Correlations between Anthropometric Measurements and Sports Discipline Aptitude.
(MDPI, 2022-06-22)Background: Sports specialization is required for the advancement of elite-level skills of a competitor. Therefore, this study attempted to assess the applicability of anthropometric measurements for a tailored selection ... -
A vaccination model for COVID-19 in Gauteng, South Africa
(KeAi Communications Co., 2022-09)The COVID-19 pandemic provides an opportunity to explore the impact of government mandates on movement restrictions and non-pharmaceutical interventions on a novel infection, and we investigate these strategies in early-stage ... -
Cattle dung in aquatic habitats alters mosquito predatory biocontrol dynamics
(Elsevier, 2022-09)Anthropogenic land use changes influence ecosystem functioning and may alter trophic interactions. Intensification of free–range pastoral farming could promote degradation of aquatic habitats, with nutrient inputs adversely ...
