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 ...
Evaluation of two Non-Edible, Wild Indigenous Botswana Crops (Croton megalobotrys (Motsebi/Letsebi/Moshoole) and Ricinus communis (Mokhure)) as Potential Feedstocks for Petroleum and Cosmetic Industries
(EAST AFRICAN NATURE & SCIENCE ORGANIZATION, 2021-12-07)
Croton megalobotrys and Ricinus cummunis plants produce high-quality nonedible seed oils at relatively high quantities of 39.65 ± 0.06 % w/w to 53.74 ± 0.04 % w/w. The Iodine values of 85.97 ± 1.62 g I2/100 g to 96.51 ± ...
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 ...
Unlocking the potential of smallholder dairy farm: Evidence from the central highland of Ethiopia.
(Elsevier, 2022-12-01)
Sustainable livestock farming practices have the potential to improve productivity and high income, reduce greenhouse gases, and improve household food security. Despite previous efforts to disseminate these technologies, ...
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 ...
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 ...
Changes in Health-related Parameters Associated with Sports Performance Enhancement Drugs.
(Thieme Gruppe, 2022-12-02)
The purpose of this study was to evaluate changes in health-related parameters caused by the administration of anabolic-androgenic steroids and fat-burning drugs during a 6-month competition preparation period. The ...
