Effect of dung and dung beetle application on topsoil fungal assemblage of a post-coal mining reclamation land: Towards soil health improvement
(Elsevier B.V., 2023)Soil management practices such as organic matter input can ameliorate soil health, including microbial com munities that are crucial for ecological processes. In this study, the effect of successive application of cattle ... -
Dietary inclusion of marama bean (Tylosema esculentum) in broiler chicken diets compromises feed utilization, growth performance, and carcass traits
(Elsevier B.V., 2023-12)Orphan legumes that are native to semi-arid areas of southern Africa, such as marama (Tylosema esculentum) bean, hold promise as sustainable nutrient sources in conventional broiler diets. Yet, their nutritive value ... -
Novel insights into the genetics, morphology, distribution and hosts of the global fish parasitic digenean Proctoeces maculatus (Looss, 1901) (Digenea: Fellodistomidae)
(Cambridge University Press, 2023)Larval stages of the widely distributed digenean species Proctoeces maculatus (Looss, 1901) were reported 40 years ago from South Africa in the common octopus, Octopus vulgaris Cuvier (Octopodidae). However, the absence ... -
The effects of habitat loss and fragmentation on the relative abundance and conservation of Southern Black Korhaan Afrotis afra, a South African endemic
(Cambridge University Press, 2023)Southern Black Korhaan is “Vulnerable” to extinction and a South African endemic that is restricted to the area of the Northern Cape Province that is west of the Great Escarpment, and to the area south of the Great ... -
A ‘One Health’ perspective of Africa-wide distribution and prevalence of Giardia species in humans, animals and waterbodies: a systematic review and meta-analysis
(Cambridge University Press, 2023-05)Giardiasis, caused by Giardia duodenalis, is a leading cause of diarrhoea in resource-poor countries. To gain a better insight into the epidemiology of Giardia in Africa, we undertook a robust study to comprehend the ... -
Mechanical and thermal properties of extrudates produced from discarded coal fines and recycled plastics as binders
(ACS Publications, 2023)This study focuses on the extrusion of discarded coal fines from the Highveld coalfield together with recycled low-density polyethylene (LDPE) and polypropylene (PP) which are used as binders to produce agglomerates with ... -
Unlocking water potential in drylands: Quicklime and fly ash enhance soil microbiome structure, ecological networks and function in acid mine drainage water-irrigated agriculture
(Heliyon, 2024)In water-stressed regions, treated acid mine drainage (AMD) water for irrigated agriculture is a potential solution to address freshwater scarcity. However, a significant knowledge gap exists on the short and long-term ... -
Unpacking the Municipal demarcation application in South Africa
(University of Johannesburg, 2022)The year 2022 marks the sixth democratic local municipal demarcation process in South Africa. The Municipal Demarcation Board has invited the public to put forward their suggestions for the revision of local municipal ... -
An internal flow and heat transfer inside a solid rocket motor combustion chamber : a lie symmetry approach
(Elsevier, 2022)The validity of Solid Rocket Motor (SRM) stability calculations critically depends on the sufficiently detailed and physically correct representation of propellant velocity flow-field, which leads to well behaved flow. A ... -
Lifestyle influences changes in fibrin clot properties over a 10-year period on a population level
(Georg Thieme Verlag, 2022)Case–control and observational studies have provided a plausible mechanistic link between clot structure and thrombosis. We aimed to identify lifestyle, demographic, biochemical, and genetic factors that influence changes ... -
Evaluation of the antioxidative potential of diisopropyldithiocarbamates sodium salt on diclofenac-induced toxicity in male albino rats
(Elsevier, 2022)Diclofenac (DIC) is a non-steroidal anti-inflammatory drug (NSAID) which is known to induce oxidative stress. Dithiocarbamates are compounds with proven antioxidant effect. The aim of the present study was to investigate ... -
Building blocks in Planning research methodology : a roadmap to research design options
(Sun Media, 2022)Making sense of the myriad of available research design options is generally an arduous task for researchers. Proper research design is, subsequently, often neglected in Planning research, resulting in superficial research ... -
Sex-specific behavioral effects of acute exposure to the neonicotinoid clothianidin in mice
(Elsevier Inc, 2022)Although neonicotinoids are among the major classes of pesticides that affect mammalian nervous systems, little is known about sex differences in their effects. This study aimed to examine whether the neurobehavioral ... -
Dissolution of titanium dioxide nanoparticles in synthetic biological and environmental media to predict their biodurability and persistence
(Elsevier BV, 2022)Investigating the biodurability and persistence of titanium dioxide nanoparticles (TiO2 NPs) is of paramount importance because these parameters influence the particles' impact on human health and the environment. Contrary ... -
Dissolution kinetics of silver nanoparticles : behaviour in simulated biological fluids and synthetic environmental media
(Elsevier, 2022)Silver nanoparticles offer a wide range of benefits including their application in several fields such as medical, food, health care, consumer, and industrial purposes. However, unlocking this potential requires a ... -
Determinants of solid fuel use and emission risks among households : insights from Limpopo, South Africa
(MDPI AG, 2022)Emissions from residential solid fuels reduce ambient air quality and cause indoor air pollution resulting in adverse human health. The traditional solid fuels used for cooking include coal, straws, dung, and wood, with ... -
Aflatoxins in maize : can their occurrence be effectively managed in Africa in the face of climate change and food insecurity?
(MDPI AG, 2022)The dangers of population-level mycotoxin exposure have been well documented. Climate-sensitive aflatoxins (AFs) are important food hazards. The continual effects of climate change are projected to impact primary agricultural ... -
Ecotoxicological effects of aflatoxins on earthworms under different temperature and moisture conditions
(MDPI AG, 2022)Aflatoxin contamination remains one of the most important threats to food safety and human health. Aflatoxins are mainly found in soil, decaying plant material and food storage systems and are particularly abundant during ...
