  9. Fine-scale drivers of African Penguin prey dynamics in Algoa Bay, South Africa, and their impacts on penguin foraging ecology by Mcinnes, Alistair McIntyre

    Published 2017
    “…There is growing evidence that variation in the availability of their principle prey, pelagic shoaling fish, are driving this trend. This prey variability is driven by oceanographic factors as well as commercial purse-seine fishing operations. …”

  11. Identification of natural product stereochemistry via calculation of ECD spectra by Lolli, Riccardo

    Published 2019
    “…Furthermore, the spectra were calculated in four different solvents, using the implicit SMD method, in order to inform future studies about “variable solvent circular dichroism”. Different conformations of a molecule can be controlled by the choice of solvent and it is hypothesised that a change in solvent will result in a “fingerprint” shift in the ECD spectra that could permit assignment of the stereochemistry. …”

  14. Spatial and temporal variations in the geometry and composition of the Permian Whitehill Formation South Africa by Chukwuma, Kenneth

    Published 2017
    “…With this aim, this study applied a combination of field descriptions, vintage borehole data, micro- to nano-scale petrographic observations, and multiple geochemical data so that a more critical understanding of the sedimentological controls responsible for the variability can be established. …”

    Published 2018
    “…These have then been integrated into a detailed landscape evolution model for the PTA. The principal controls on the stratigraphic development of the PTA are rate of sediment input and relative sea-level (RSL) fluctuations. …”

    Published 2020
    “…Seventy-one un-intubated X-rays from 85 controls were used to identify normal ratios. The authors measured vertebral bodies and soft tissue at each level, created all possible ratios, then chose the two least variable – one for the upper and one for the lower C-spine. …”
