On the model for U Geminorum by Harwood, John Malcolm

“…The term cataclysmic variable comprises several types of variable star - novae, recurrent novae, dwarf novae; and to these we add the nova-like variables, stars which exhibit many of the characteristics of the novae but which have not been observed to erupt. …”

Life history traits of South African Encephalartos spp. (Zamiaceae) and their implications for understanding population structure, responses to threats and effective conservation a... by Konings, Kim Martina

“…An analysis of environmental variables for 193 populations of species in all groups, including maximum and minimum temperatures, mean annual precipitation, moisture index, rainfall co-efficient of variation and fire return frequency, showed that the means per group were not significantly different from each other for most of the variables. …”

The application of advanced signal processing techniques to the condition monitoring of electrical machine drive systems by Barendse_PS

“…Presently, the well established condition monitoring techniques are based on steadystate analysis of various diagnostic variables (i.e. current, voltage, power, etc.). These steadystate techniques are currently being applied to most machine-related applications, however it is well known that machine diagnostic variables behave typically as non-stationary signals. …”

Psychosocial predictors of HIV treatment outcomes among young pregnant and postpartum women living with HIV by Noholoza, Sandisiwe

“…Each psychosocial risk factor threshold met scored the participant one point on psychosocial burden such that the minimum score was zero and the maximum was four. The prevalence of each exposure variable was analyzed using descriptive statistics and associations between them and with the outcome variables (engagement in care and HIV viral load <50 copies/mL) were examined using Chi2 tests and Fischer exact tests for sparse data. …”
