A first assessment of glyphosate, 2,4-D and Cry proteins in surface water of South Africa
(ASSAf, 2019)Agriculture plays a vital role in the South African economy, as well as in the production of maize for food. Genetically modified maize is transformed to encode for crystalline (Cry) proteins found in Bacillus thuringiensis ... -
The Chaplygin gas as a model for modified teleparallel gravity?
(Springer, 2019)This paper explores the possibility of treating the exotic Chaplygin-gas (CG) fluid model as some manifestation of an f(T) gravitation. To this end, we use the different cosmological CG equations of state, compare them ... -
Oribatid mites (Acari, Oribatida) inhabiting termite nests in the Faan Meintjes Nature Reserve (South Africa)
(Systematic and Applied Acarology Society, 2019)The present study is based on oribatid mite material (Acari, Oribatida) collected from nests of the termite Trinervitermes trinervoides (Sjöstedt, 1911) (Isoptera, Termitidae) of the Faan Meintjes Nature Reserve in South ... -
A new species of the mesopelagic isopod genus Xenuraega Tattersall, 1909 (Crustacea: Isopoda: Aegidae) from Japan, the second species in the genus
(Magnolia Press, 2019)Xenuraega bythionekta sp. nov., is described from a single specimen taken off southern Japan. It is the second species of Xenuraega Tattersall, 1909, and extends the known range of the genus from North Atlantic to the ... -
Serpinema cayennensis n. sp. (Nematoda: Camallanidae), a parasite of the freshwater turtle Rhinoclemmys punctularia Daudin (Reptilia: Testudines: Geoemydidae) from French Guiana: morphology and phylogenetic relationships with other turtle-parasitising camallanids
(Magnolia Press, 2019)The genus Serpinema was erected from the genus Camallanus to include species parasitising freshwater turtles. Following this, the taxonomic status of Serpinema was challenged by different authors considering it as a subgenus ... -
Three new species of acanthocephalans (Palaeacanthocephala) from marine fishes collected off the East Coast of South Africa
(Institute of Parasitology, Biology Centre CAS, 2019)Three new species of acanthocephalans are described from marine fishes collected in Sodwana Bay, South Africa: Rhadinorhynchus gerberi n. sp. from Trachinotus botla (Shaw), Pararhadinorhynchus sodwanensis n. sp. from ... -
Groundwater as an alternative source to irregular surface water in the O'Kiep area, Namaqualand, South Africa
(Elsevier, 2019)Water insecurity is a growing concern globally and the role of groundwater and aquifers in buffering the effects of climate variability and change is increasingly acknowledged due to extended periods of drought in arid ... -
A system CFD model of the heat transfer in a prismatic block of a VHTR
(SAAM, 2018)The conduction heat transfer through the prismatic blocks containing the fuel elements in a Very High Temperature Reactor (VHTR) is of crucial importance for the proper operation of the reactor under normal operating ... -
Comparison of the modelled maximum wireless link distance for TVWS and Wi-Fi within South African regulatory constraints: which technology wins and in which scenarios?
(IEEE, 2019)The work compares Wi-Fi and television white space (TVWS) technologies for practical broadband communication links, specifically in rural areas. The paper starts with an overview of advantages and limitations of Wi-Fi and ... -
Modelling of convection heat transfer in the SNU Riser Heat transfer Experimental Facility (RHEF)
(SAAM, 2018)The Reactor Cavity Cooling System (RCCS) of a High Temperature Gas-cooled Reactor (HGTR) plays an important role in ensuring the integrity of the HTGR during normal operating and accident conditions. The performance of ... -
CFD analysis of thermal dispersion in a structured packed bed
(SACAM, 2018)Packed beds are generally modelled in a partial manner to avoid computational costs. This implies that only a small portion of the representative bed is modelled explicitly in CFD simulations, usually by assuming ... -
Simulation of suction recirculation in double suction centrifugal pumps
(SACAM, 2018)Part-load operation conditions of a centrifugal pump will impose potentially strenuous effects on the operation and reliability of the turbomachine in question due to the risk of suction recirculation. Suction recirculation ... -
Solar powered peltier cooling storage for vaccines in rural areas
(IJEECS, 2019)The research presented in this paper proposes a new design of a vaccine cooling and storage unit that can keep vaccines in the cold chain (2°C to 8°C). This design was done to facilitate effective completion of the ... -
Removal of naphthalene from simulated wastewater through adsorption-photodegradation by ZnO/Ag/GO nanocomposite
(Elsevier, 2020)In this study, a ZnO/Ag/GO nanocomposite was synthesised and used as photocatalyst for effective photodegradation of naphthalene from simulated wastewater under visible light. Chemical and morphological characterisation ... -
Pathological consequences of drug abuse: implication of redox imbalance. Editorial
(Hindawi, 2019)The onset, progression, and outcome of numerous pathological conditions, affecting different organs and systems, have been widely reported to be significantly impacted by the abuse of psychoactive compounds. In the last ... -
Assessment of post-operative pain medication adherence after day case orthopaedic surgery: a prospective, cross-sectional study
(Elsevier, 2020)Background and aim Patients struggle to adhere to prescribed pain medication after surgery because of, inter alia, side effects, sleep disturbances and pain severity. This study aimed to determine the influence of various ... -
Cultural specific attitudes of Batswana people towards adoption
(Stellenbosch Univ, 2019)The aim of this study was to describe the cultural attitude of Batswana people towards adoption. The study employed a cross-sectional survey design and is descriptive in nature. It followed a quantitative approach and ... -
’n Lewensvaardigheidsprogram vir straatkinders: aanwending van die lewenskaartetegniek in maatskaplike groepwerkverband
(Stellenbosch Univ, 2019)The focus of this article is to indicate how the life map technique was applied in the development of a life skills program for street children in order to promote the psychosocial functioning of street children. A literature ... -
Preterm perinatal hypoxia-ischemia does not affect somatosensory evoked potentials in adult rats
(MDPI, 2019)Somatosensory evoked potentials (SSEPs) are a valuable tool to assess functional integrity of the somatosensory pathways and for the prediction of sensorimotor outcome in perinatal injuries, such as perinatal hypoxia-ischemia ... -
A call for improved reporting on serious adverse events in clinical trials
