Remote Sensing Grassland Productivity Attributes: A Systematic Review
(MDPI, 2023)A third of the land on the Earth is composed of grasslands, mainly used for forage. Much effort is being conducted to develop tools to estimate grassland productivity (GP) at different extents, concentrating on spatial and ... -
Remote sensing of land use-land cover change and climate variability on hydrological processes in Sub-Saharan Africa: Key scientific strides and challenges
(Taylor and Francis Group, 2022)The impact of land use land cover (LULC) change and climatevariability on water resources poses as a major threat in semi-aridenvironments, especially in the sub-Saharan Africa. Countries insub-Saharan Africa are vulnerable ... -
Remotely sensed applications in monitoring the spatio-temporal dynamics of pools and flows along non-perennial rivers: A review
(Taylor and Francis Group, 2022)Non-perennial rivers (NPRs) account for more than 50% of the world’s river network and their occurrence is expanding. Some rivers that were previously classified as perennial have evolved to be NPRs in response to climate ... -
Remotely sensed c3 and c4 grass species aboveground biomass variability in response to seasonal climate and topography
(Wiley Online Library, 2019)Seasonal climate and topography influence C3 and C4 grass species aboveground biomass (AGB). Climate change further threatens these grasses AGB, thereby compromising their ability to provide ecosystem goods and services. ... -
Remotely sensed data for estimating chlorophyll-a concentration in wetlands located in the Limpopo Transboundary River Basin, South Africa
(Physics and Chemistry of the Earth, 2022)Wetlands in semi-arid regions are highly productive and biologically diverse ecosystems that contribute significantly to livelihood and economic development and play a substantial role in sustaining rural livelihoods. These ... -
Removal of pharmaceutical residues from water and wastewater using dielectric barrier discharge methods—A review
(MPDI, 2021)Persistent pharmaceutical pollutants (PPPs) have been identified as potential endocrine disruptors that mimic growth hormones when consumed at nanogram per litre to microgram per litre concentrations. Their occurrence in ... -
Renewing Felsenstein’s phylogenetic Bootstrap in the era of big data
(Nature Publishing Group, 2018)Felsenstein’s application of the bootstrap method to evolutionary trees is one of the most cited scientific papers of all time. The bootstrap method, which is based on resampling and replications, is used extensively to ... -
Renosterveld conservation in South Africa: A case study for handling uncertainty in knowledge-based neural networks for environmental management
(International Society for Environmental Information Sciences, 2009)This work presents an artificial intelligence method for the development of decision support systems for environmental management and demonstrates its strengths using an example from the domain of biodiversity and ... -
Reply to Pallotti et al. comment on “Boitrelle et al. The sixth edition of the who manual for human semen analysis: A critical review and swot analysis. Life 2021, 11, 1368"
(MDPI, 2022)We would like to thank F. Pallotti and his colleagues for their positive comments [1] on our SWOT analysis of the strengths, weaknesses, threats and opportunities of the sixth edition of the WHO manual on semen analysis ... -
Reports of plant-derived nanoparticles for prostate cancer therapy
(MDPI, 2023)Plants have demonstrated potential in providing various types of phytomedicines with chemopreventive properties that can combat prostate cancer. However, despite their promising in vitro activity, the incorporation of these ... -

Reports of Plant-Derived Nanoparticles for Prostate Cancer Therapy
(Plants, 2023)Background: Plants have demonstrated potential in providing various types of phytomedicines with chemopreventive properties that can combat prostate cancer. However, despite their promising in vitro activity, the incorporation ... -
Reproductive health situation in South Africa: Emerging policy issue
(SAGE Publications, 2018)South Africa is still lagging behind with health outcomes, especially when it comes to accessing treatment, prevention and care for reproductive health issues despite the significant progress made with regard to certain ... -
Repurposing based identification of novel inhibitors against mmps5-mmpl5 efflux pump of Mycobacterium smegmatis: A combined in silico and in vitro study
(MDPI, 2022)In the current era of a pandemic, infections of COVID-19 and Tuberculosis (TB) enhance the detrimental effects of both diseases in suffering individuals. The resistance mechanisms evolving in Mycobacterium tuberculosis ... -
Research and development of hydrogen carrier based solutions for hydrogen compression and storage
(IOP Publishing, 2022)Industrial and public interest in hydrogen technologies has risen strongly recently, as hydrogen is the ideal means for medium to long term energy storage, transport and usage in combination with renewable and green ... -
Resilience and sustainability of the water sector during the Covid-19 pandemic
(MDPI, 2022)The COVID-19 pandemic brought unprecedented socio-economic changes, ushering in a “new (ab)normal” way of living and human interaction. The water sector was not spared from the effects of the pandemic, a period in which ... -
Response of soybean nodules to exogenously applied caffeic acid during NaCl-induced salinity
(Elsevier, 2015)affeic acid acts as an antioxidant to scavenge reactive oxygen species, but its influence on plant responses to abi- otic stresses is only partially understood. Here, we investigated the influence of exogenously applied ... -
Response to letter to the Editor: The therapeutic strategy of drug re-positioning to induce autophagic cell death in brain malignancy
(Springer Nature, 2021)We thank Dr Yoshida for his valuable comments and interest in our study which describes the anti-cancer activity of DS00329, a novel derivative of the anti-psychotic drug phenothiazine, in glioblastoma multiforme (GBM) ... -
The rest-frame UV luminosity function at z 4: A significant contribution of AGNs to the bright end of the galaxy population
(Oxford University Press, 2020)We measure the rest-frame ultraviolet (UV) luminosity function (LF) at z ∼ 4 self-consistently over a wide range in absolute magnitude (−27 ≲ MUV ≲ −20). The LF is measured with 46 904 sources selected using a photometric ...
