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. ...
Estimating above-ground biomass in sub-tropical buffer zone community Forests, Nepal, using Sentinel 2 data
(MDPI, 2018)
Accurate assessment of above-ground biomass (AGB) is important for the sustainable
management of forests, especially buffer zone (areas within the protected area, where restrictions
are placed upon resource use and special ...
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 ...
Characterising the water use and hydraulic properties of riparian tree invasions: A case study of Populus canescens in South Africa
(Water Research Commission, 2018)
Invasive alien plants (IAPs) pose a serious threat to the already limited water resources in dry countries like South Africa
which are facing increasing water shortages. Much of South Africa is expected to get drier in ...
Geochemistry and weathering history of the Balfour sandstone formation, Karoo basin, South Africa: Insight to provenance and tectonic setting
(Elsevier, 2018)
Geochemical analysis on sandstones from clastic sediments was carried out to understand the tectonic setting and subsequent post-depositional change in the Karoo basinal fill of the fluvial deposits of the Balfour Formation ...
The performance of photometric reverberation mapping at high redshift and the reliability of damped random walk models
(Oxford University Press, 2020)
Accurate methods for reverberation mapping using photometry are highly sought after since
they are inherently less resource intensive than spectroscopic techniques. However, the effectiveness
of photometric reverberation ...
Application of multi‑method approach to assess groundwater–surface water interactions, for catchment management
(Springer, 2018)
Globally, the dependence of river systems to delayed discharge of subsurface water to augment flows during dry seasons is well documented. Discharge of fresh subsurface water can dilute concentrated river flow quality ...
