Data on the optimisation of a solid phase extraction method for fractionating estrogen metabolites from small urine volumes
(Elsevier, 2020)Certain estrogen metabolites have been implicated in the pathophysiology of breast cancer. Moreover, the estrogen metabolite profiles of healthy women and those with (a high risk of) breast cancer differ significantly. The ... -
Data protection laws and privacy on Facebook
(AOSIS, 2015)Background: Social networks have changed the way people communicate. Business processes and social interactions revolve more in the cyber space. However, as these cyber technologies advance, users become more exposed to ... -
Data transformations and goodness-of-fit tests for type-II right censored samples
(Springer, 2015)We suggest several goodness-of-fit (GOF) methods which are appropriate with Type-II right censored data. Our strategy is to transform the original observations from a censored sample into an approximately i.i.d. sample ... -
The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project
(Wiley, 2017)The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples ... -

The day after no tomorrow? Persons displaced environmentally through climate change: AU law to the rescue?
(VerLoren van Themaat Centre for Public Law Studies, 2010)The phenomenon of so-called 'environmental refugees' has received thorough consideration from scholars. The dire consequences of climate change in relation to migration patterns have placed the focus on 'environmental ... -
A "Day in the lives" of four resilient youths: cultural roots of resilience
(SAGE Publications, 2011)Grounded in the examples of four impoverished, relocated youths (two Sesotho-speaking orphans in South Africa and two Mexican immigrants in Canada), we explore cultural factors as potential roots of resilience. We triangulate ... -

DC electrical conductivity of nano-composite polystyrene–titanium– arsenate membrane
(ELSEVIER, 2013)In continuation to our previous work with nano-composite polystyrene–titanium–arsenate (PS–Ti–As), we further extended the characterization by means of DSC, TEM and mercury porosimetry measurements. In addition to the ... -
DC power quality emulator
(IEEE, 2020)Currently, no dc power quality standards exist. The lack of dc power quality (PQ) standards can be addressed by, amongst others, evaluating the impact of PQ deviations on consumer end equipment. A voltage disturbance ... -
Dc-bus voltage balancing controllers for split dc-link four-wire inverters and their impact on the quality of the injected currents
(IET, 2017)The increasing share of single-phase distributed generation units in low-voltage grids causes voltage unbalance problems and overvoltages. Therefore, the need for power quality improving control strategies of grid-connected ... -
DDT and malaria prevention: addressing the paradox
(Superintendent of Documents, 2011)Background The debate regarding dichlorodiphenyltrichloroethane (DDT) in malaria prevention and human health is polarized and can be classified into three positions: anti-DDT, centrist-DDT, pro-DDT. Objective We ... -

DDTs and other organochlorine pesticides in tissues of four bird species from the Rift Valley region, Ethiopia
(Elsevier, 2017)Despite the presence of a wide variety and number of birds, there is exceedingly little data on organochlorine pesticide (OCP) residues in birds inhabiting in Africa. In the present study, concentrations of dichlorodiphe ... -
De/acculturation of identity: diaspora in selected photo installations by Searle and Farber
(AHWG, 2015)This article investigates the de/acculturation of identity (as brought forth specifically by diaspora) as visually represented by contemporary South African artists Berni Searle and Leora Farber. Specific focus is placed ... -
Dealing with bioethical dilemmas: a survey and analysis of responses from ministers in the Reformed Churches in South Africa
