How to build science-action partnerships for local land-use planning and management: Lessons from Durban, South Africa
(Resilience Alliance, 2016)The gap between scientific knowledge and implementation in the fields of biodiversity conservation, environmental management, and climate change adaptation has resulted in many calls from practitioners and academics to ... -
Alternative mechanisms for delivery of medication in South Africa: A scoping review
(AOSIS, 2021)Background: The number of people in South Africa with chronic conditions is a challenge to the health system. In response to the coronavirus infection, health services in Cape Town introduced home delivery of medication ... -
The effect of finite halo size on the clustering of neutral hydrogen.
(IOP, 2021)Post-reionisation 21cm intensity mapping experiments target the spectral line of neutral hydrogen (HI) resident in dark matter haloes. According to the halo model, these discrete haloes trace the continuous dark matter ... -
Testing the equivalence principle on cosmological scales using the odd multipoles of galaxy cross-power spectrum and bispectrum
(IOP, 2021)One of the cornerstones of general relativity is the equivalence principle. However, the validity of the equivalence principle has only been established on solar system scales for standard matter fields; this result ... -
Synthesis, characterization and ab initio study of WO3 nanocubes with peculiar electrochemical properties
(Springer, 2021)Simple sol–gel method has been exploited to deposit Sn-doped TiO2 thin flms on glass substrates. The resultant coatings were characterized by X-ray difraction (XRD), UV–visible techniques (UV–Vis), Fourier transform ... -
Synthesis and characterization of Sn‑doped TiO2 flm for antibacterial applications
(Springer, 2021)Simple sol–gel method has been exploited to deposit Sn-doped TiO2 thin flms on glass substrates. The resultant coatings were characterized by X-ray difraction (XRD), UV–visible techniques (UV–Vis), Fourier transform ... -
Statistical gamma-ray decay studies at iThemba LABS
(EDP Sciences, 2017)Abstract. A program to study the γ -ray decay from the region of high-level density has been established at iThemba LABS, where a high-resolution gamma-ray detector array is used in conjunction with silicon particle-telescopes. ... -
Relativistic mean field formulation of clustering in heavy nuclei
(IOP, 2010)Very little is known about clustering in heavy nuclei and in particular the interaction between the correlated cluster nucleons and remaining core nucleons. Currently the phenomenological Saxon-Woods plus cubic Saxon-Woods ... -
Observation of the 0+ 2 and γ bands in 98Ru, and shape coexistence in the Ru isotopes
(Elsevier, 2020)Excited states in 98Ru were investigated using γ-ray spectroscopy following the β-decay of 98Rh, and via the 100Ru(p,t) reaction. Combining the results from the two experiments, two states were revised to have spin-parity ... -
Modern African nuclear detector laboratory: Development of state-of-the-art in-house detector facility at the University of the Western Cape
(SpringerLink, 2021)The upcoming detector facility aims at developing new state-of-the-art particle detectors as well as providing hands-on training to postgraduate students using both analog and digital signal processing from nuclear radiation ... -
Cheminformatic Profiling and Hit Prioritization of Natural Products with Activities against Methicillin-Resistant Staphylococcus aureus (MRSA)
(Molecules, 2021-06)Several natural products (NPs) have displayed varying in vitro activities against methicillin-resistant Staphylococcus aureus (MRSA). However, few of these compounds have not been developed into potential antimicrobial ... -
Cashew nut testa tannin resin – preparation, characterization and adsorption studies
(Journal of Taibah University for Science, 2021-06)Adsorption of metal ions and dyes from water by cashew nut testa tannin resin (CATAR) was studied and the effects of temperature, initial pH, initial concentration and time were investigated. Scanning electron microscopy ... -
Antimycobacterial Activity, Synergism, and Mechanism of Action Evaluation of Novel Polycyclic Amines against Mycobacterium tuberculosis
(Advances in Pharmacological and Pharmaceutical Sciences, 2021-06)Mycobacterium tuberculosis has developed extensive resistance to numerous antimycobacterial agents used in the treatment of tuberculosis. Insufficient intracellular accumulation of active moieties allows for selective ... -
The potential of chalcone-capped gold nanoparticles for the management of diabetes mellitus
(Surfaces and Interfaces, 2021-08)Searching for new natural bioactive capping agents represent an urgent priority in the green synthesis of metal nanoparticles. Additionaly, the biosaftey of metal nanparticles is a major concern especially in medical ... -
The Relationship between Cadmium Toxicity and the Modulation of Epigenetic Traits in Plants
(International Journal of Molecular Sciences, 2021-06)Elevated concentrations of heavy metals such as cadmium (Cd) have a negative impact on staple crop production due to their ability to elicit cytotoxic and genotoxic effects on plants. In order to understand the relationship ... -
PR-1-Like Protein as a Potential Target for the Identification of Fusarium oxysporum: An In Silico Approach
(BioTech, 2021-07)Fusarium oxysporum remains one of the leading causes of economic losses and poor crop yields; its detection is strained due to its presentation in various morphological and physiological forms. This research work sought ... -
Synthesis of 4-oxatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione derivatives as lead scaffolds for neuroprotective agents
(Arkivoc, 2020-09)Neurodegenerative disorders are characterised by progressive loss of neuronal functions. Of the proposed mechanisms, excitotoxicity, mediated by prolonged glutamate activation and calcium overload, is prominent. NGP1-01, ... -
