Factors associated with mothers’ health care‑seeking behaviours for childhood fever in Burkina Faso: Findings from repeated cross‑sectional household surveys
(BMC, 2022)Fever is one of the most frequent reasons for paediatric consultations in Burkina Faso, but health careseeking behaviours and the factors associated with health care-seeking in the event of childhood fever are poorly documented. ... -
Factors associated with patellofemoral pain in recreational road cyclists: A cross-sectional study in 59953 cyclists – SAFER XXXIII
(Elsevier, 2023)Patellofemoral pain (PFP) is a common cycling-related injury, and independent factors need to be identified to enable effective injury prevention strategies. We aim to determine factors associated with PFP in cyclists ... -
Factors influencing pigment production by halophilic bacteria and its effect on brine evaporation rates
(Wiley, 2018)The disposal of reject brine, a highly concentrated waste by-product generated by various industrial processes, represents a major economic and environmental challenge. The common practice in dealing with the large ... -
Factors influencing sustainability of communally-managed waterfacilities in rural areas of Zimbabwe
(Elsevier, 2017)Sustainability of point water facilities is a major development challenge in many rural settings ofdeveloping countries not sparing those in the Sub-Saharan Africa region. This study was done inZimbabwe to investigate the ... -
Factors influencing the awareness and adoption of borehole-garden permaculture in Malawi: Lessons for the promotion of sustainable practices
(MPDI, 2021)Using wastewater accumulating around rural waterpoints to irrigate community gardens, borehole-garden permaculture (BGP) presents a method of sustainable water management. BGP also presents public health benefits through ... -
Factors that influence cape fur seal predation on Cape gannets at Lambert’s bay, South Africa
(PeerJ, 2022)Seabird populations experience predation that can impact their breeding density and breeding success. The Cape gannet Morus capensis is endemic to the Benguela upwelling ecosystem and is classified as Endangered by the ... -
The faint radio source population at 15.7 GHz - II. Multi-wavelength properties
(Oxford University Press, 2015)A complete, flux density limited sample of 96 faint (> 0:5 mJy) radio sources is selected from the 10C survey at 15.7 GHz in the Lockman Hole. We have matched this sample to a range of multi-wavelength catalogues, including ... -
The faint radio source population at 15.7 GHz – IV. The dominance of core emission in faint radio galaxies
(Oxford University Press, 2020)We present 15-GHz Karl G. Jansky Very Large Array observations of a complete sample of radio galaxies selected at 15.7 GHz from the Tenth Cambridge (10C) survey. 67 out of the 95 sources (71 per cent) are unresolved in the ... -
The faint source population at 15.7 GHz - I. The radio properties
(Oxford University Press, 2013)We have studied a sample of 296 faint (>0.5 mJy) radio sources selected from an area of the Tenth Cambridge (10C) survey at 15.7 GHz in the Lockman Hole. By matching this catalogue to several lower frequency surveys (e.g. ... -
Fast tracking students from disadvantaged backgrounds into main stream Computer Science
(Computer Society of South Africa, 2000)A computer-based training (CBT) system was used to teach Computer Literacy to full-time students at the University of the Western Cape. This approach was successful in creating computer literate students as well as creating ... -
Fate of sulphate removed during the treatment of circumneutral mine water and acid mine drainage with coal fly ash: Modelling and experimental approach
(Elsevier, 2011)The treatment of acid mine drainage (AMD) and circumneutral mine water (CMW) with South African coal fly ash (FA) provides a low cost and alternative technique for treating mine wastes waters. The sulphate concentration ... -
An Fe@Fe3C-inserted carbon nanotube/graphite composite supportproviding highly dispersed Pt nanoparticles for ethanol oxidation
(Elsevier, 2014)Iron/iron carbide-inserted carbon nanotube/graphite composite (Fe-C) was prepared by pyrolyzing amixture of melamine and iron (III) chloride to form a support for high loading of Pt nanoparticles as adirect ethanol fuel ... -
Feasibility assessment of the application of groundwater remediation techniques in rural areas: A case study of rural areas in the Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater contribution towards human health and livelihood depends on the contaminants level in groundwater. Many people in rural communities are being exposed to waterborne diseases resulting from drinking untreated ... -
Feasibility of solar-powered groundwater pumping systems in rural areas of greater Giyani municipality (Limpopo, South Africa)
(MDPI, 2023)Rural areas in Limpopo Province (South Africa) are in urgent need of interventions for safe and secure water supply to adapt to climatic changes and the increased frequency of droughts. A feasibility study was conducted ... -
Feature guided training and rotational standardization for the morphological classification of radio galaxies
(Oxford University Press, 2023)State-of-the-art radio observatories produce large amounts of data which can be used to study the properties of radio galaxies. However, with this rapid increase in data volume, it has become unrealistic to manually process ... -
Feature Reduction for the Classification of Bruise Damage to Apple Fruit Using a Contactless FT-NIR Spectroscopy with Machine Learning
