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 ...
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 ...
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 ...
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 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 ...
Substitution kinetics of platinum N,N,N’,N’-Tetrakis (2-pyridyl methyl) octane diamine aqua complex with thiourea, glutathione and L-cysteine nucleophiles
(Al-Kindi Center for Research and Development, 2020)
The ligand substitution kinetics of the platinum(II) complex, [Pt2(L)(OH2)2](ClO4)4 (L = N, N,N’,N’- tetrakis (2-pyridylmethyl) octane diamine) by a series of nucleophiles, viz. thiourea (TU), L-cystein (LCYST), and ...
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 ...
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 ...
Determination of the aroma properties of Mustard seeds by SPME - GC-MS
(Greener Journal of Biological Sciences, 2021-10-10)
The objective of this study was to investigate the volatile aroma
constituents of mustard seeds grown in Ethiopia by using SPME-GC-MS.
In the analysis several sulfur contained compounds were identified. The ...
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. ...
