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
