The thousand-pulsar-array programme on MeerKAT – I. Science objectives and first results
(Oxford University Press, 2020)We report here on initial results from the Thousand-Pulsar-Array (TPA) programme, part of the Large Survey Project ‘MeerTime’ on the MeerKAT telescope. The interferometer is used in the tied-array mode in the band from 856 ... -
The thousand-pulsar-array programme on meerkat – Viii. the subpulse modulation of 1198 pulsars
(Oxford University Press, 2023)We report on the subpulse modulation properties of 1198 pulsars using the Thousand-Pulsar-Array programme on MeerKAT. About 35 per cent of the analysed pulsars exhibit drifting subpulses that are more pronounced towards ... -
The Thousand-Pulsar-Array programme on MeerKAT – XIII. Timing, flux density, rotation measure, and dispersion measure time series of 597 pulsars
(Oxford, 2024)We report here on the timing of 597 pulsars over the last four years with the MeerKAT telescope. We provide times of arrival, pulsar ephemeris files, and per-epoch measurements of the flux density, dispersion measure (DM), ... -
The threat of aerobic vaginitis to pregnancy and neonatal morbidity
(Women's Health and Action Research Centre, 2017)Aerobic vaginitis (AV) is an endogenous opportunistic infection brought about by the disruption of the normal vaginal microbiota. Its early diagnosis and treatment during pregnancy may reduce the risk of negative pregnancy ... -
The threat of Covid-19 on food security: A modelling perspective of scenarios in the informal settlements in Windhoek
(MDPI, 2023)Due to the heterogeneity among households across locations, predicting the impacts of stay-at-home mitigation and lockdown strategies for COVID-19 control is crucial. In this study, we quantitatively assessed the effects ... -
The threat of trade-based money laundering To the African continental free trade area
(University of the Western Cape, 2018)Africa has dedicated considerable effort to establishing a Continental Free Trade Area to facilitate intra-African trade and deepen economic integration. However, the liberalisation and facilitation of trade on the ... -
Threats to e-government implementation in the civil service: Nigeria as a case study
(Akamai University, 2012)The rapid advancement in Information and Communication Technology (ICT) has undoubtedly influenced positive changes in carrying out administrative functions in government institutions. The ICT adoption rate in Africa is ... -
The three hundred project: The stellar and gas profiles
(Oxford University Press, 2020)Using the catalogues of galaxy clusters from The Three Hundred project, modelled with both hydrodynamic simulations (GADGET-X and GADGET-MUSIC), and semi-analytical models (SAMs), we study the scatter and self-similarity ... -
Three novel bacteria associated with two centric diatom species from the Mediterranean Sea, Thalassiosira rotula and Skeletonema marinoi
(MPDI, 2021)Diatoms are a successful group of microalgae at the base of the marine food web. For hundreds of millions of years, they have shared common habitats with bacteria, which favored the onset of interactions at different ... -
Three species of Mastophora (Rhodophyta: Corallinales, Corallinaceae) in the tropical Indo-Pacific Ocean: M. rosea (C. Agardh) Setchell, M. pacifica (Heydrich) Foslie, and M. multistrata sp. nov
(International Phycological Society, 2009)Three species of Mastophora (Corallinaceae, Corallinales, Rhodophyta) were found in extensive studies of non-geniculate coralline algae in various areas of the tropical Indo-Pacific, including French Polynesia, Fiji, Ryukyu ... -

Three-dimensional N-doped super-hydrophilic carbon electrodes with porosity tailored by Cu2O template-assisted electrochemical oxidation to improve the performance of electrical double-layer capacitors
(Royal Society of Chemistry, 2021)Three-dimensional (3D), binder-free, porous carbon-based electrodes exhibit high charge storage ability in electrical double-layer capacitors owing to their well-developed porous structures enhancing mass transfer and ... -
A three-pronged approach to waste composition determination
(Elsevier, 2022-02-01)Understanding solid waste composition has frequently been cited as one of the most valuable resources to those responsible for the proper management of solid waste. The unique contribution of this article lies in the fact ... -
A three-tier approach to protect groundwater resources in South Africa
(Water Research Commission, 1995)The quality of groundwater is affected by many activities occurring on the surface of the earth. A pro-active protection approach is required to avoid the costly and technology difficult exercise of groundwater remediation. ... -
Through the lens of a peer: understanding leisure boredom and risk behaviour in adolescence
(Occupational Therapy Association of South Africa, 2011)There has been very little research investigating leisure boredom and risk behaviour among adolescents in South Africa. Using a qualitative approach, this study investigated adolescents’ perceptions of leisure boredom and ... -
The tianlai cylinder pathfinder array: System functions and basic performance analysis
(Springer, 2020)The Tianlai Cylinder Pathfinder is a radio interferometer array designed to test techniques for 21 cm intensity mapping in the post-reionization Universe, with the ultimate aim of mapping the large scale structure and ... -
Tillage practices affect weeds differently in monoculture vs. crop rotation
(Elsevier, 2020)Reduced tillage practices are widely considered to be more sustainable than conventional tillage practices, but many producers remain reluctant to reduce tillage due to difficulties controlling weeds. Crop rotation is often ... -
The time is burning: The right of adults to basic education in South Africa
(Journal of Education, 2006)The government has neglected the constitutional right of adults to basic education over the last decade. This paper examines the bases for holding the government to account in the constitutional court for its performance. ... -
Time series models of three sets of RXTE Observations of 4U 1543-47
(Oxford University Press, 2013)The X-ray nova 4U 1543−47 was in a different physical state (low/hard, high/soft, and very high) during the acquisition of each of the three time series analyzed in this paper. Standard time series models of the ... -
