Dynamical and optimal control analysis of a seasonal Trypanosoma brucei rhodesiense model.
(AIMS Press, 2020-02-27)The effects of seasonal variations on the epidemiology of Trypanosoma brucei rhodesiense disease is well documented. In particular, seasonal variations alter vector development rates and behaviour, thereby influencing the ... -
A fractional-order Trypanosoma brucei rhodesiense model with vector saturation and temperature dependent parameters.
(Springer Open, 2020-06-11)Temperature is one of the integral environmental drivers that strongly affect the distribution and density of tsetse fly population. Precisely, ectotherm performance measures, such as development rate, survival probability ... -
Fuzzy Modeling for the Dynamics of Alcohol-Related Health Risks with Changing Behaviors via Cultural Beliefs.
(HINDAWI, 2020-07-13)In this paper, we propose and analyze a fuzzy model for the health risk challenges associated with alcoholism. The fuzziness gets into the system by assuming uncertainty condition in the measure of influence of the risky ... -
Mathematical modeling of the dynamics of health risks associated with alcoholism in Tanzania: a literature review.
(SCIK Publishing Corporation, 2020-07-13)In this paper, a number of alcohol related studies have been reviewed in light of the strength and challenges of the models developed for their applicability in Tanzanian drinking context. The aim of this paper is to provide ... -
Significance of antiviral therapy and CTL-mediated immune response in containing hepatitis B and C virus infection.
(Elsevier B. V., 2021-01-12)Viral infections remain a major cause of deaths globally. Here, we focus on Hepatitis B and C viruses (HBV and HCV) infection dynamics in the liver and blood cells, taking into account non-cytotoxic and cytotoxic mediated ... -
A Mathematical Model of Contact Tracing during the 2014–2016 West African Ebola Outbreak.
(MDPI Open Access Journals, 2021-03-12)The 2014–2016 West African outbreak of Ebola Virus Disease (EVD) was the largest and most deadly to date. Contact tracing, following up those who may have been infected through contact with an infected individual to prevent ... -
Modelling the Control of the Impact of Fall Armyworm (Spodoptera frugiperda) Infestations on Maize Production.
(Hindawi, 2021-03-18)In this paper, we propose and analyse a stage-structured mathematical model for modelling the control of the impact of Fall Armyworm infestations on maize production. Preliminary analysis of the model in the vegetative and ... -
Modeling the Effect of HIV/AIDS Stigma on HIV Infection Dynamics in Kenya.
(Springer Link, 2021-04-05)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 pre- ventative measures while also causing PLWHA to avoid testing and ... -
Dynamics for a non-autonomous fall armyworm-maize interaction model with a saturation functional response
(AIMS Press, 2021-11-09)In this study, we present a non-autonomous model with a Holling type II functional response, to study the complex dynamics for fall armyworm-maize biomass interacting in a periodic environment. Understanding how seasonal ... -
A fractional-order fall armyworm-maize biomass model with naturally beneficial insects and optimal farming awareness.
(Elsevier, 2021-11-01)Maize remains an important food crop in Africa. However, the production of this crop, and consequently the livelihood of the growers are threatened by the invasion and widespread infestation of the fall armyworm which ... -
Evaluation of variety alone or in combination with diatomaceous earth or pyriproxyfen (an insect growth regulator) for managing plodia Interpunctella (hubner) (lepidoptera; pyralidae) on stored groundnuts (arachis hypogaea L.)
(Botswana University of Agriculture & Natural Resources, 2018-09)In storage, insect pests cause considerable losses to stored groundnut (Arachis hypogaca L.) and one of the major storage pests worldwide is Plodia interpunctella (Hubner). Two experiment were conducted to evaluate the ... -
Evaluation of the diversity and pest status of fruit flies on marula, Sclerocarya Birrea in Gabane, Mochudi and Rasesa
(Botswana University of Agriculture & Natural Resources, 2011-07)Manila (Sclerocarya birrea) is one of the most useful indigenous trees in Africa. The fruits of marula are used to produce useful products such as juice, jam and beer. The seed kernels are very rich in proteins and can be ... -
Quantitative assessment and transfers of potentially toxic metals from soils to vegetable crops in urban and peri-urban agriculture land use system in Botswana.
(Botswana University of Agriculture & Natural Resources, 2015-08)Urban and peri-urban agriculture (UPA) is considered an important source of food for cities and for vulnerable households. It is usually characterized by high input intensity and use of wastewater for irrigation. The ... -

(Botswana University of Agriculture & Natural Resources, 2011-07)An experiment was conducted al the Botswana College of Agriculture (BCA), Gaborone, Botswana (24° 55’S, 25" 95’E) at an altitude of 998m above sea level to evaluate the effectiveness of Bacillus thuringiensis(Bt), ... -
Phosphate sorption and its relation to soil properties
(Agricultural University of Norway, 1986-12-11)In order to study the phosphorus sorption characteristics of six soils from Botswana, 2g of soil were equilibrated at 20°C in 0.01M CaCl2 containing various amounts of dissolved phosphate (0-900 pg P/g soil for two days). ... -
An assessment of biological nitrogen fixation on legumes growing on farmers’ fields and in natural systems and authentication of associated root nodule bacteria
