Characterising the water use and hydraulic properties of riparian tree invasions: A case study of Populus canescens in South Africa
(Water Research Commission, 2018)Invasive alien plants (IAPs) pose a serious threat to the already limited water resources in dry countries like South Africa which are facing increasing water shortages. Much of South Africa is expected to get drier in ... -
An in-depth study of the ICT ecosystem in a South African rural community: unveiling expenditure and communication patterns
(Routledge, 2016)There is no doubt of the contributions made by mobile phones and mobile network operators in increasing access to communications in rural areas of developing countries. Yet how affordable is this ubiquitous access in such ... -
Moving ICTD research beyond bungee jumping: practical case studies and recommendations
(Institute of Electrical and Electronics Engineers, 2016)The global spread of Internet and mobile communications has been accompanied by a growing interest in how information and communication technologies (ICTs) can contribute to social and economic development. There are a ... -
Exploration of Deaf people’s health information sources and techniques for information delivery in Cape Town: A qualitative study for the design and development of a mobile health application
(JMIR Publications, 2016)BACKGROUND: Many cultural and linguistic Deaf people in South Africa face disparity when accessing health information because of social and language barriers. The number of certified South African Sign Language interpreters ... -
Developments in the remote sensing of soil erosion in the perspective of sub-Saharan Africa. Implications on future food security and biodiversity
(Elsevier, 2018)The remote sensing of soil erosion has gained substantial consideration, with considerable scientific research work having been conducted in the past, due to technological improvements that have resulted in the release of ... -
Essential metal and metalloid elements in the Philippi Horticultural area, and their uptake into selected vegetable crops
(Taylor & Francis, 2018)This study evaluated Co, Cr, Mn, Ni, Se, Sn and V status in the soils of the PHA, as well as the vegetables produced on these soils. We also determined the agronomic sources of these elements to the soils in the PHA. ... -
The organisation of urban agriculture in Cape Town, South Africa: A social capital perspective
(Taylor & Francis, 2018)This article explores urban agriculture in Cape Town and its organisational forms. Based on a literature review of peerreviewed articles and grey literature, it examines the state of linkages among urban farmers and various ... -
Cross-species multiple environmental stress responses: An integrated approach to identify candidate genes for multiple stress tolerance in sorghum (Sorghum bicolor (L.) Moench) and related model species
(Public Library of Science, 2018)BACKGROUND Crop response to the changing climate and unpredictable effects of global warming with adverse conditions such as drought stress has brought concerns about food security to the fore; crop yield loss is a major ... -
Brown rot-type fungal decomposition of sorghum bagasse: variable success and mechanistic implications
(Hindawi Publishing Corporation, 2018)Sweet sorghum is a promising crop for a warming, drying African climate, and basic information is lacking on conversion pathways for its lignocellulosic residues (bagasse). Brown rot wood-decomposer fungi use carbohydra ... -
A 35-gene signature discriminates between rapidly- and slowly-progressing glioblastoma multiforme and predicts survival in known subtypes of the cancer
(BioMed Central, 2018)BACKGROUND: Gene expression can be employed for the discovery of prognostic gene or multigene signatures cancer. In this study, we assessed the prognostic value of a 35-gene expression signature selected by pathway ... -
Transformation between phreatic water and soil water during freeze–thaw periods
(MDPI, 2018)During freeze–thaw periods, the exchange between shallow groundwater and soil water is unusually strong and bidirectional, which causes soil salinization and affects the accuracy of water resources assessment. The ... -
Analyses of HIV-1 integrase sequences prior to South African national HIV-treatment program and available of integrase inhibitors in Cape Town, South Africa
(Nature Publishing Group, 2018)HIV-Integrase (IN) has proven to be a viable target for highly specific HIV-1 therapy. We aimed to characterize the HIV-1 IN gene in a South African context and identify resistance-associated mutations (RAMs) against ... -
Understanding the spatial distribution of eroded areas in the former rural homelands of South Africa: Comparative evidence from two new non-commercial multispectral sensors
(Elsevier, 2018)In this study, we determine the most suitable multispectral sensor that can accurately detect and map eroded areas from other land cover types in Sekhukhune rural district, Limpopo Province, South Africa. Specifically, the ... -
Vaginal microbiomes associated with aerobic vaginitis and bacterial vaginosis
(Frontiers Media, 2018)A healthy vaginal microbiota is considered to be significant for maintaining vaginal health and preventing infections. However, certain vaginal bacterial commensal species serve an important first line of defense of the ... -
News from the EREBOS project
(De Gruyter Open, 2017)Planets and brown dwarfs in close orbits will interact with their host stars, as soon as the stars evolve to become red giants. However, the outcome of those interactions is still unclear. Recently, several brown dwarfs ... -
