Advances in the use of biocontrol applications in preharvest and postharvest environments: a food safety milestone
(John Wiley & Sons, Inc., https://onlinelibrary.wiley.com/journal/17454565, 2022-04)
Increasing concerns toward food safety and public health have rendered the use of synthetic chemicals in agricultural environments unacceptable. A shift toward biologically safe approaches has been considered a preferred ...
Contaminant binding and bioaccessibility in the dust from the Ni-Cu mining/smelting District of Selebi-Phikwe (Botswana)
(Wiley Periodicals LLC, https://www.wiley.com/, 2022-08-22)
We studied the dust fractions of the smelting slag, mine tailings, and soil from the former Ni-Cu mining and processing district in Selebi-Phikwe (eastern Botswana). Multi-method chemical and mineralogical
investigations ...
Spectral angle mapping and AI methods applied in automatic identification of placer deposit magnetite using multispectral camera mounted on UAV
(https://www.mdpi.com, 2022-02-20)
The use of drones in mining environments is one way in which data pertaining to the state of a site in various industries can be remotely collected. This paper proposes a combined system that employs a 6-bands multispectral ...
Coupling NCA dimensionality reduction with machine learning in multispectral rock classification problems
(MDPI, https://www.mdpi.com/, 2021-08-05)
Though multitudes of industries depend on the mining industry for resources, this industry has taken hits in terms of declining mineral ore grades and its current use of traditional, time consuming and computationally ...
Biosurfactant production by halophilic yeasts isolated from extreme environments in Botswana
(Oxford University Press, https://academic.oup.com/femsle, 2021)
Nine morphologically distinct halophilic yeasts were isolated from Makgadikgadi and Sua pans, as pristine and extreme environments in Botswana. Screening for biosurfactant production showed that Rhodotorula mucilaginosa ...
Technological advances in phytopathogen detection and metagenome profiling techniques
(Springer Science+Business Media, LLC, part of Springer Nature 2020, https://www.springer.com/journal/284, 2020)
The use of advanced molecular methods in plant pathology and applied microbiology has necessitated for more accurate, rapid detection and identification of plant pathogens. This is particularly significant given accelerated ...
Prevalence of Cryptosporidium parvum, Giardia intestinalis and molecular characterization of group A rotavirus associated with diarrhea in children below five years old in Gaborone, Botswana
(Pan African Medical Journal, https://www.panafrican-med-journal.com/, 2020-10-14)
Introduction
Cryptosporidium, Giardia and rotaviruses are amongst the leading causes of acute gastroenteritis in children ≤5 years worldwide. The purpose of this study was to determine the occurrence of Cryptosporidium ...
Electron-LO-phonon intrasubband scattering rates in a hollow cylinder under the influence of a uniform axial applied magnetic field
(Springer Science+Business Media, LLC, part of Springer Nature, https://www.springer.com/journal/11082, 2021-11-06)
Scattering rates arising from the interactions of electrons with bulk longitudinal optical (LO) phonon modes in a hollow cylinder are calculated as functions of the inner radius and the uniform axial applied magnetic field. ...
Wildfires in Botswana and their frequency of occurrence
(Scientific Research Publishing Inc., https://www.scirp.org/journal/journalarticles.aspx?journalid=492, 2021-09-13)
Fires play an essential part in the maintenance of the environment, but amplified fire activity often leads to adverse effects in the environment such as destruction of property and loss of life. Botswana has experienced ...
Probing semiconductor quantum well qubits and associated Shannon entropy using semi‑relativistic quantum mechanics
(Springer Nature, https://www.springer.com/, 2023-08-07)
Electron states in GaAs, GaN and AlN quantum wells are studied by solving a semi-relativistic wave equation within the effective mass approximation. The quantum states are in turn used to probe the properties of two-level ...
