Petrophysical interpretation and fluid substitution modelling of the upper shallow marine sandstone reservoirs in the Bredasdorp Basin, offshore South Africa
(Springer Nature, 2020)
The fluid substitution method is used for predicting elastic properties of reservoir rocks and their dependence on pore fluid
and porosity. This method makes it possible to predict changes in elastic response of a rock ...
Potential of resampled multispectral of data for detecting desmodium-brachiaria intercropped with maize in a push-pull system
(ISPRS, 2020)
Poor crop yields remain one of the main causes of chronic food insecurity in Africa. This is largely caused by insect pests, weeds, unfavourable climatic conditions and degraded soils. Weed and pest control, based on the ...
Erratum: The frequency of very young galaxies in the local Universe: II. The view from SDSS spectra
(Oxford University Press, 2020)
Only a handful of galaxies in the local Universe appear to be very young. We estimate the
fraction of very young galaxies (VYGs), defined as those with more than half their stellar
masses formed within the last Gyr. We ...
Big data analytics and its role to support groundwater management in the Southern African development community
(MDPI, 2020)
Big data analytics (BDA) is a novel concept focusing on leveraging large volumes of
heterogeneous data through advanced analytics to drive information discovery. This paper aims to
highlight the potential role BDA can ...
Planck 2018 results: IV. Diffuse component separation
(EDP Sciences, 2020)
We present full-sky maps of the cosmic microwave background (CMB) and polarized synchrotron and thermal dust emission, derived from the third set of Planck frequency maps. These products have significantly lower contamination ...
Planck 2018 results: II. low frequency Instrument data processing
(EDP Sciences, 2020)
We present a final description of the data-processing pipeline for the Planck Low Frequency Instrument (LFI), implemented for the 2018 data
release. Several improvements have been made with respect to the previous release, ...
Urban tracer dispersion and infiltration into buildings over a 2-km scale
(Springer Nature, 2020)
Field experiments were undertaken in the summer of 2015 in Manchester, UK, to investigate the dispersion behaviour and infiltration into buildings of gas-phase pollutants over horizontal distances of 1–5 km. Inert cyclic ...
Impacts of plastic debris on biota and implications for human health: A South African perspective
(South African Assn. For The Advancement Of Science, 2020)
Entanglement and ingestion of plastics are the main ecological impacts of marine plastic debris on marine biota, but indirect effects such as the transport of alien species and benthic smothering are also important to note. ...
The impact of land-use/land cover changes on water balance of the heterogeneous Buzi sub-catchment, Zimbabwe
(Elsevier, 2020)
The nature of interactions between ecological, physical and hydrological characteristics that determine the effects
of land cover change on surface and sub-surface hydrology is not well understood in both natural ...
The EXOTIME project: Signals in the O-C diagrams of the rapidly pulsating subdwarfs DW Lyn, V1636 Ori, QQ Vir, and V541 Hya.
(EDP Sciences, 2020)
We aim to investigate variations in the arrival time of coherent stellar pulsations due to the light-travel time effect to test for the
presence of sub-stellar companions. Those companions are the key to one possible ...
