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 ... -
Six main contributing factors to high levels of mycotoxin contamination in African foods
(MDPI AG, 2022)Africa is one of the regions with high mycotoxin contamination of foods and continues to record high incidences of liver cancers globally. The agricultural sector of most African countries depends largely on climate variables ... -
Hematology and biochemical values in equines naturally infected with Theileria equi in Nigeria
(Kluwer Academic Publishers, 2022)Equine piroplasmosis (EP) is a tick-borne disease of equines with resultant economic consequences. To date, little information is available regarding the effects of EP on the health of equids in Nigeria. Therefore, this ... -
Association between host genetics of sheep and the rumen microbial composition
(Kluwer Academic Publishers, 2022)A synergy between the rumen microbiota and the host genetics has created a symbiotic relationship, beneficial to the host’s health. In this study, the association between the host genetics and rumen microbiome of Damara ... -
Growth, physiological performance, and pork quality of weaner large white piglets to different inclusion levels of nano zinc oxide
(Kluwer Academic Publishers, 2023)Thirty intensively reared piglets averaged 7.6 ± 0.32 kg were used for the experiment. The piglets were randomly allotted to 5 different treatments: 200 mg/kg, 400 mg/kg, 600 mg/kg nano zinc oxide (nZnO; 50 nm), positive ... -
