How many species of angulate tortoises occur in Southern Africa? (Testudines: Testudinidae: Chersina)
(Wiley-Blackwell, 2020)
Using range-wide sampling and 1,143 bp of mtDNA (cytochrome b gene) and 14 microsatellite loci, we examined genetic differentiation in the widely distributed Southern African angulate tortoise (Chersina angulata). We found ...
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, ...
Synthesis and cytotoxic evaluation of gum arabic surface modified cadmium telluride quantum dots
(American Scientific Publishers, 2020)
Water-soluble cadmium telluride (CdTe) quantum dots (QDs) were capped with gum Arabic (GA) is a non-toxic,
water-soluble glycoprotein polymer commonly used in the food and pharmaceutical industries. The GA was
used to ...
Are claudin-5 tight-junction proteins in the blood-brain barrier porous?
(Wolters Kluwer Health, 2020)
The capillaries of the brain are particularly special, as they are not
simply conduits for blood, but are primarily responsible to ensure that
the neurons function in a strictly regulated homeostatic interstitium.
Brain ...
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. ...
4-Oxatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione derivatives as NMDA receptor- and VGCC blockers with neuroprotective potential
(MDPI, 2020)
The impact of excitotoxicity mediated by N-methyl-D-aspartate (NMDA) receptor
overactivation and voltage gated calcium channel (VGCC) depolarization is prominent among
the postulated processes involved in the development ...
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 ...
Diet composition and some observations on the feeding ecology of the rhizostome Rhopilema nomadica in Israeli coastal waters
(Cambridge University Press, 2020)
Since the mid-1980s, swarms of the rhizostome Rhopilema nomadica have been an annual phenomenon in Israeli Mediterranean coastal waters during the summer months. Despite its annual prominence and the potential impact on ...
