Heterosis and combining ability of iron, zinc and their bioavailability in maize inbred lines under low nitrogen and optimal environments
(Cell Press, 2023)Iron (Fe) and zinc (Zn) nutrient enrichment of staple crops through biofortification can contribute to alleviating micronutrient deficiency in sub-Saharan Africa. A line × tester mating design was used to determine the ... -
Overcoming barriers for people with disabilities participating in income-generating activities: a proposed development framework
(AOSIS, 2023)Background: People with disabilities in sheltered workshops are disempowered and face many barriers, adversely affecting their income-generating activities and weakening their competitiveness in the labour market. There ... -
Combining ability estimates for quality and non-quality protein maize inbred lines for grain yield, agronomic, and quality traits
(Frontiers, 2023)Introduction: Biofortified maize varieties could contribute to the fight against hunger and malnutrition of the increasing human population and help meet the high demand of maize for human consumption, industrial use and ... -
Permissionless blockchain systems as pseudo-random number generators for decentralized consensus
(IEEE, 2023)Consensus algorithms that function in permissionless blockchain systems must randomly select new block proposers in a decentralised environment. Our contribution is a new blockchain consensus algorithm called Proof-of-Publicly ... -
Candida albicans-enteric viral interactions—the prostaglandin E2 connection and host immune responses
(Cell Press, 2023)The human microbiome comprises trillions of microorganisms residing within different mucosal cavities and across the body surface. The gut microbiota modulates host susceptibility to viral infections in several ways, and ... -
Enhancing household welfare through perennial crop production in Northern Ghana
(MDPI, 2023)As Ghana seeks to diversify its agricultural export commodity trade away from its over-reliance on cocoa, empirical evidence is critical to inform policy direction on the implementation of programs to promote such an agenda. ... -
Strengthening Namibia's flood early warning system through a critical gap analysis
(MDPI, 2023)Floods are considered leading hydrometeorological disasters, which are increasing in frequency, intensity and complexity with the evolution of climate change. Their associated impacts have detrimental and often prolonged ... -
Susceptibility tests and predictions of transporter profile in Serratia species
(MDPI, 2022)Disinfectants and biosecurity are critically important to control microbial diseases. Resistance to disinfectants compromises sectors such as agriculture and healthcare systems. Currently, efflux pumps are the most common ... -
Filamentous fungi for sustainable remediation of pharmaceutical compounds, heavy metal and oil hydrocarbons
(Frontiers, 2023)This review presents a comprehensive summary of the latest research in the field of bioremediation with filamentous fungi. The main focus is on the issue of recent progress in remediation of pharmaceutical compounds, heavy ... -
Effects of the density of invasive Lantana camera plants on the biodiversity of large and small mammals in the Groenkloof Nature Reserve (GNR) in South Africa
(MDPI, 2023)Multi-scale approaches have been used to determine scales at which mammal species are responding to habitat destruction due to invasion, but the impacts of weeds on mammals have not been extensively studied, especially in ... -
Candida albicans-enteric viral interactions—the prostaglandin E2 connection and host immune responses
(Cell Press, 2023)The human microbiome comprises trillions of microorganisms residing within different mucosal cavities and across the body surface. The gut microbiota modulates host susceptibility to viral infections in several ways, and ... -
The search for high-energy gamma-ray emission from the close binary system AR Scorpii using Fermi-LAT data
(University of the Free State, 2021-10)AR Scorpii (AR Sco) is an enigmatic close binary system which is observable across most of the electromagnetic spectrum. Multi-wavelength emission consists of both thermal and non-thermal components, where pulsed non-thermal ... -
The search for pulsed radio and gamma-ray emission from the cataclysmic variable system AE Aquarii using MeerKAT and Fermi-LAT data
(University of the Free State, 2021-12)The nova-like AE Aquarii was extensively studied using 11 years of data and contemporaneous optical data with the aim to establish pulsed gamma-ray emission at the rotational period (33.08 s) of the white dwarf and the ... -
A novel approach to determine the surface area of buckspoor spider webs and other irregular-shaped two-dimensional objects
(Elsevier, 2022)Arising from the practical need to determine the surface area of the buckspoor spider webs of Seothyra schreineri, an approach for area determination was developed based on image processing. The method rendered results ... -
Youth participation in agriculture, accounting for entrepreneurial dimensions
(AOSIS, 2022)Background: Despite the high youth unemployment levels, especially in sub-Saharan Africa, participation in the agricultural sector remains low. The agricultural sector provides valuable opportunities of employment, which ... -
Does adoption of climate change adaptation strategy improve food security? A case of rice farmers in Ogun State, Nigeria
(MDPI, 2022)The southwestern part of Nigeria, particularly Ogun State, is more vulnerable to the vagaries of climate change due to the high dependence on rain-fed agriculture and limited capacities to respond to climate change. In ... -
Fusion-extraction technique of vanadium(III) using ammonium phosphate salt as flux
(MDPI, 2022)This study presents an alternative fusion method for sample dissolution and extraction of vanadium from an inorganic (V2O3) compound and mineral ore sample (AMIS 0501) using phosphate salts as flux. Complete sample dissolution ... -
Tuneable blue to orange phosphor from Sm3+ doped ZnAl2O4 nanomaterials
(Elsevier, 2022)Undoped and Sm3+ doped ZnAl2O4 nanopowders were synthesized using the co-precipitation method and annealed at 750 ℃ for 3.5 h. The aim of this study was to investigate the effect of varying the Sm3+ concentration on the ... -
The ground spider genera Leptodrassex Murphy, 2007 and Leptopilos Levy, 2009 (Araneae: Gnaphosidae) in southern Africa, including the description of a new genus and seven new species
(Magnolia Press, 2022)The ground spider genera Leptodrassex Murphy, 2007 and Leptopilos Levy, 2009 are recorded from southern Africa for the first time, with the description of five new species: Leptodrassex murphyi sp. nov. (♂ ♀) from Mozambique ... -
The effect of selenium foliar application on the physiological responses of edamame under different water treatments
(MDPI, 2022)Drought has devastating effects on crops, posing enormous risks to food security. This study investigated the impact of foliar applied selenium [at four concentrations (25, 50 and 75 mg/L)] on the photosynthesis capacity, ...
