Effects of temperature and storage time on the motility, viability, DNA integrity and apoptosis of processed human spermatozoa
(Wiley, 2019)The aim of this study was to evaluate motility, viability, DNA integrity and apoptosis of spermatozoa when washed semen samples were kept for up to 12 days at 4–6°C and 25°C. In this experimental study, 26 normozoospermic ... -
Effects of uterine fundal massage on number of postpartum haemorrhage cases at a level 2 maternity hospital in the Western Cape, South Africa
(AFAHPER-SD, 2014)Globally, as well as in South Africa, postpartum haemorrhage (PPH) due to uterine atony is the number one direct cause of maternal mortality associated with the postpartum period. Active management of the third stage of ... -
Effects of wild and farm-grown macroalgae on the growth of juvenile South African abalone Haliotis midae Linnaeus
(Taylor and Francis, 2011)The effect of various macroalgal diets on the growth of grow-out (> 20 mm shell length) South African abalone Haliotis midae was investigated on a commercial abalone farm. The experiment consisted of four treatments: fresh ... -
Efficacy of rights based management within an ecosystems approach to fisheries - Small pelagics in South Africa

Efficacy of rights-based management of small pelagic fish within an ecosystems approach to fisheries in South Africa
(Taylor & Francis, 2013)South Africa’s small pelagics fishery is moving towards a management strategy using an ecosystem approach to fisheries (EAF), with rights-based management (RBM) as the key rights allocation system. While EAF strives to ... -
The efficacy of zingiber officinale on dyslipidaemia, blood pressure, and inflammation as cardiovascular risk factors: A systematic review
(Clinical Nutrition ESPEN, 2022)Background & aims: Hypertension, dyslipidaemia, and chronic inflammation contribute to the development of cardiovascular disease (CVD). Zingiber officinale has been suggested to reduce these CVD risk factors; however, the ... -
Efficiency, food security and differentiation in small-scale irrigation agriculture: Evidence from North West Nigeria
