Anode materials for lithium-ion batteries: A review
(Elsevier, 2022)The need for eco-friendly and portable energy sources for application in electrical, electronic, automobile and even aerospace industries has led to an ever-increasing research and innovation in lithium-ion battery technology. ... -
Anomalous gas in ESO 149-G003: A MeerKAT-16 view
(Oxford University Press, 2021)ESO 149-G003 is a close-by, isolated dwarf irregular galaxy. Previous observations with the ATCA indicated the presence of anomalous neutral hydrogen (H I) deviating from the kinematics of a regularly rotating disc. We ... -
Another countryside? Policy options for land and agrarian reform in South Africa
(Institute for Poverty, Land and Agrarian Studies, University of the Western Cape, 2009)Land reform in South Africa is a political project that has foundered. For years, the process has been variously described as being ‘in crisis’, ‘at a crossroads’, ‘at an impasse’ or simply ’stuck’. This still seems as ... -
Another countryside? Policy options for land and agrarian reform in South Africa
(Institute for Poverty Land and Agrarian Studies (PLAAS), 2009)Land reform in South Africa is a political project that has foundered. For years, the process has been variously described as being ‘in crisis’, ‘at a crossroads’, ‘at an impasse’ or simply ’stuck’. This still seems as ... -
Another piece to the epidemiological puzzle of traumatic spinal cord injury in Cape Town, South Africa: A population-based study2018
(Health and Medical Publishing Group, 2018)The epidemiology of traumatic spinal cord injury (TSCI) is poorly understood in developing countries. In South Africa (SA) specifically, two healthcare systems (private v. government funded) exist, and it is therefore ... -
Antarctic Dry Valley mineral soils contain unexpectedly high levels of microbial biomass
(Springer Verlag, 2002)We have applied bioluminescent ATP detection methods to microbial enumeration in Antarctic Dry Valley mineral soils, and validated our ATP data by two independent methods. We have demonstrated that ATP measurement is ... -
Antenna beam characterization for the global 21-cm experiment LEDA and its impact on signal model parameter reconstruction
(Oxford University Press, 2022)Cosmic dawn, the onset of star formation in the early universe, can in principle be studied via the 21-cm transition of neutral hydrogen, for which a sky-averaged absorption signal, redshifted to MHz frequencies, is predicted ... -
Antennal enriched odorant binding proteins are required for odor communication in glossina f. Fuscipes
(MPDI, 2021)Olfaction is orchestrated at different stages and involves various proteins at each step. For example, odorant-binding proteins (OBPs) are soluble proteins found in sensillum lymph that might encounter odorants before ... -
The Anthropocene crisis and higher education: A fundamental shift
(South African Association for Research and Development in Higher Education (SAARDHE), 2016)This article seeks to address a fundamental shift that has occurred in reality; a displacement that requires us to critically account for the ways in which knowledge is both being produced and taught at universities. The ... -
Anthropometric indices and cut-off points for screening of metabolic syndrome among South African taxi drivers
(Frontiers Media, 2022)Detecting the early onset of metabolic syndrome (MetS) allows for quick intervention which may slow progression to a variety of health consequences, hence, determining the best measurement to detect MetS is essential. ... -
Anti-lensing: the bright side of voids
(American Physical Society, 2013)More than half of the volume of our Universe is occupied by cosmic voids. The lensing magni ca- tion e ect from those under-dense regions is generally thought to give a small dimming contribution: objects on the far side ... -
Antibacterial activities of bacteria isolated from the marine sponges Isodictya compressa and Higginsia bidentifera collected from Algoa Bay, South Africa
(MDPI AG, 2017)Due to the rise inmulti-drug resistant pathogens and other diseases, there is renewed interest in marine sponge endosymbionts as a rich source of natural products (NPs). The South African marine environment is rich in ... -
Antibacterial Activities of Selected Green Seaweeds from West African Coast
(EC Pharmacology and Toxicology ECronicon Open Access, 2020)The continually increasing antibiotic resistance amongst microorganisms had steered up an increased intensity in the search for new drugs. The marine environment had been reported to be a great source of novel compounds ... -
Antibacterial activity of biogenic silver and gold nanoparticles synthesized from Salvia africana-lutea and Sutherlandia frutescens
(Nanotechnology, 2020)Nanoparticles (NPs) synthesized using various chemical and physical methods are often cytotoxic which restricts their use in biomedical applications. In contrast, metallic biogenic NPs synthesized using biological systems ... -
