Linking multi-epoch CCD photometry of partially overlapping fields
(Oxford University Press, 2013)A common problem in CCD photometry is to combine measurements obtained at different epochs. This is especially challenging if the fields only overlap partially, and are sparse, so that not all calibrating stars are ... -
‘Lockdown’: Digital and emergency elearning technologies—A student perspective
(MDPI, 2022)The COVID-19 pandemic and the subsequent emergency measures had a fundamental and disruptive impact on societies and, in particular, on the educational sector. The transition of the modality of educational delivery from ... -

(AOSIS, 2018)INTRODUCTION: Unplanned pregnancy is a community health concern. Research with South African women revealed the complexities surrounding pregnancy planning. Categorising pregnancies as either planned or unplanned is ... -
Long-term eclipse timing of white dwarf binaries: an observational hint of a magnetic mechanism at work
(Oxford University Press, 2016)We present a long-term programme for timing the eclipses of white dwarfs in close binaries to measure apparent and/or real variations in their orbital periods. Our programme includes 67 close binaries, both detached and ... -

(BMJ Publishing Group, 2018)OBJECTIVES: To determine the incidence and nature of injuries in the Super Rugby tournament over a 5-year period. METHODS: 482 male professional rugby union players from six South African teams participating in the ... -
Maternal mental health and infant neurodevelopment at 6 months in a low-income South African cohort
(Infant Mental Health Journal, 2022)Maternal mental health disorders and the adverse consequences for infant neurodevelopment have received substantial research attention in high-income countries over the past five decades. In Africa, where relatively little ... -
Maternal mortality in Burkina Faso: a method from population census 2006
(Tehran University of Medical Sciences, 2013)Background: Estimating maternal mortality level is constantly challenging researchers and planners both in rich and poor countries. In developing countries, particularly in Burkina Faso where the registration system is not ... -
Maths4Stats: Opleiding vir onderwysers
(AOSIS, 2013)Maths4Stats: Educating teachers. The inadequate nature of the education infrastructure in South Africa has led to poor academic performance at public schools. Problems within schools such as under-qualified teachers and ... -
Matrimony relations and business in a fishing migrant community (periphery of Pointe-Noire, Congo-Brazzaville)
(l'Association des amis de la Revue de Géographie de Lyon, 2013)This paper examines the entrepreneurial activities of female migrants in the informal artisanal fishing sector along the coastal line of Congo-Brazzaville. It shows the extent to which these women have achieved an insertion ... -
Menstrual regulation: Examining the incidence, methods, and sources of care of this understudied health practice in three settings using cross-sectional population-based surveys
(BMC, 2023)Menstrual regulation is a practice that may exist within the ambiguity surrounding one’s pregnancy status and has been the subject of limited research. The aim of this study is to measure the annual rate of menstrual regulation ... -

(BMC, 2021)Women use various terms when discussing the management of their fertility and menstrual irregularities and may interpret the experience of ending a possible pregnancy in nuanced ways, especially when their pregnancy status ... -
Modelling the rotation period distribution of M dwarfs in the Kepler field
(Springer Verlag, 2018)McQuillan et al. (Mon. Not. R. Astron. Soc.432:1203, 2013) presented 1570 periods P of M dwarf stars in the field of view of the Kepler telescope. It is expected that most of these reflect rotation periods, due to starspots. ... -
More on the nature of the variable star UNSW-V-760
(Oxford University Press, 2012)The results of two multicolour time-series photometric observing runs, separated by about two months, are presented. The same periodicities previously detected in photometry of UNSWV- 760 are still present, albeit at ... -
