(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 ...
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 ...

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. ...
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 ...
