  4. Linking microbial community dynamics and performance of a biological sulphate reducing system using a mixed volatile fatty acid stream as electron donor by Motleleng, Liabo

    Published 2021
    “…In addition, Desulfocurvus vexinensis and Desulfobulbus oligotrophicus were able to function at a VSLR of 0.42 g l-1 h -1 which suggests these two SRB species could be used effectively to reduce sulphate to hydrogen sulphide in wastewaters with higher VSLRs of up to 0.42 g l-1 h -1 when lactate was provided as an electron donor for BSR. …”

  8. Geographic variation in the phenotype of an African horseshoe bat species, Rhinolophus damarensis, (Chiroptera: Rhinolophidae) by Maluleke, Tinyiko

    Published 2018
    “…Morphometric and echolocation measurements were taken from hand held individual bats in the field, and skull measurements were taken from field collected voucher specimens as well as museum specimens. Discriminant Function Analyses (DFA) revealed that there was geographic variation among populations and lineages of R. damarensis. …”

  9. A numerical assessment of architectural parameters for anisotropic behavior in idealised trabecular structures by Moore, Keelan

    Published 2019
    “…The structural anisotropy varies from fully equiaxed to highly directional based on where the trabecular bone is located and what the function would be. The mean intercept length has been proposed as a measure of the structural anisotropy, specifically the interfacial anisotropy of the sample, which is commonly used to account for the mechanical anisotropy. …”

  10. Synthesis of monodisperse silver nanoparticles for antibacterial purposes by Adam, Sarah

    Published 2019
    “…These include: further optimisation of the nanoparticle synthesis procedure so as to produce particles of the desired size and acquire them in powder form, performing a thermodynamic estimation of the equilibrium silver ion concentration as a function of silver nanoparticle size to quantify the effect nanoparticle size will have on bactericidal activity, and using more realistic water conditions for antibacterial efficacy experiments to simulate the environment in which silver nanoparticles will be applied.…”

  11. Stable isotope ecology of South African kelp forests by Dyer, David Clifford

    Published 2019
    “…Stable Isotope Analysis (SIA) is an indispensable tool for investigating food web characteristics, with particular focus on trophic structure and functioning. SIA can be used to understand the basal isotope variability in producers, determine the primary carbon sources of food webs, and investigate the spatial and temporal patterns in consumer isotope values and trophic niches. …”

  12. Characterization of Mycobacterium tuberculosis-specific Th22 cells in HIV-TB co-infection by Makatsa, Mohau Steven

    Published 2020
    “…A major focus of this thesis is the contribution of an understudied Th subset in Mtb immunity, namely Th22 cells, producing the cytokine IL-22. IL-22 functions to preserve mucosal barriers and induce antimicrobial peptides, contributing to protective immunity to a range of extracellular and intracellular bacteria. …”
