Parental reporting of adverse drug reactions in South Africa: An online survey
(AOSIS, 2021)The high incidence of adverse drug reactions (ADRs) in children is of global concern. Enhancing the reporting of ADRs could contribute to making safer medicines available to children.To assess parents’ awareness of ... -
A participatory design for a billing system: A South African case study of a community based telephony system
(ACM, 2014)This paper describes the role participatory design can play in developing and implementing an information and communication technology for development project in a rural area. It shows how the process of co-designing an ... -
Particle number concentration measurements on public transport in Bangkok, Thailand
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)Traffic is a major source of particulate pollution in large cities, and particulate matter (PM) level in Bangkok often exceeds the World Health Organisation limits. While PM2.5 and PM10 are both measured in Bangkok regularly, ... -
The pathophysiology of rhabdomyolysis in ungulates and rats: towards the development of a rodent model of capture myopathy
(Springer, 2023)Capture myopathy (CM), which is associated with the capture and translocation of wildlife, is a life-threatening condition that causes noteworthy morbidity and mortality in captured animals. Such wildlife deaths have a ... -
Pathways towards coexistence with large carnivores in production systems
(Springer, 2021)Coexistence between livestock grazing and carnivores in rangelands is a major challenge in terms of sustainable agriculture, animal welfare, species conservation and ecosystem function. Many effective non-lethal tools exist ... -
Patient with Kaposi’s Sarcoma: Teaching students medicine management therapy
(Medpharm, 2018)Interprofessional education (IPE) is a cornerstone in advancing health professional education, with the aim of improving the overall quality of healthcare.1 The World Health Organization (WHO) states: “Interprofessional ... -
Patient-Control Association Study of the Leucine-Rich Repeat Kinase 2 (LRRK2) Gene in South African Parkinson's Disease Patients
(National Institute of Health, 2013)The leucine-rich repeat kinase 2 (LRRK2) gene is of interest to Parkinson's disease (PD) as it has been implicated in both familial and sporadic forms of the disorder.1 PD-susceptibility alleles in LRRK2 appear to be ... -
Patterns of primary beam non-redundancy in close-packed 21 cm array observations
(Oxford University Press, 2021)Radio interferometer arrays such as HERA consist of many close-packed dishes arranged in a regular pattern, giving rise to a large number of ‘redundant’ baselines with the same length and orientation. Since identical ... -
PCR-based detection of non-indigenous microorganisms in ‘pristine’ environments
(Elsevier, 2003)PCR-based technologies are widely employed for the detection of specific microorganisms, and may be applied to the identification of non-indigenous microorganisms in ‘pristine’ environments. For ‘pristine’ environments ... -
Peer-to-Peer Computing and Grid Computing: towards a better understanding
(Akamai University, 2011)Currently, both Peer-to-Peer Computing (P2P) and Grid Computing have remained the most vibrant and useful forms of distributed computing all over the world. Their applications are such that they cut across both academia ... -
Peptide-functionalized quantum dots for potential applications in the imaging and treatment of obesity
(DovePress, 2018)BACKGROUND: Obesity is a worldwide epidemic affecting millions of people. The current pharmacological treatment of obesity remains limited and ineffective due to drugs’ undesirable side effects. Hence, there is a need for ... -
Performance Evaluation of a Wireless Network using a VoIP Traffic Generator on a Mobile Device
(ACM, 2014)The problem of generating different patterns of traffic to emulate real user behaviour is receiving considerable attention with the construction of new and more complex network architectures. The theoretical modelling of ... -
The performance of photometric reverberation mapping at high redshift and the reliability of damped random walk models
(Oxford University Press, 2020)Accurate methods for reverberation mapping using photometry are highly sought after since they are inherently less resource intensive than spectroscopic techniques. However, the effectiveness of photometric reverberation ... -

Performance of Richardson extrapolation on some numerical methods for a singularly perturbed turning point problem whose solution has boundary layers
(KOREAN MATHEMATICAL SOC, 2014)Investigation of the numerical solution of singularly perturbed turning point problems dates back to late 1970s. However, due to the presence of layers, not many high order schemes could be developed to solve such problems. ... -
Perinatal suicidality: Risk factors in South African women with mental illness
(OpenJournals Publishing AOSIS (Pty) Ltd, 2020)Maternal Mortality is a global health concern. The lack of suicide data, particularly in low and middle income countries, is concerning and needs to be addressed. Aim: This study assessed suicidality and associated factors ... -
Periodic low-frequency electric field structures in a magnetized non-thermal auroral plasma
(Elsevier, 2019)The theoretical explanation of electric field structures associated with density depletion in the Earth’s upper ionosphere is presented. Using the quasi-neutrality hypothesis, the effect of excess energetic electron ... -
Periodic variations in the O-C diagrams of five pulsation frequencies of the DB white dwarf EC 20058-5234
(American Physical Society, 2013)Variations in the pulsation arrival time of five independent pulsation frequencies of the DB white dwarf EC 20058−5234 individually imitate the effects of reflex motion induced by a planet or companion but are inconsistent ... -
Permian to cretaceous granites and felsic volcanics from SW Vietnam and S Cambodia: Implications for tectonic development of Indochina
(Asian Earth Sciences, 2021)Zircon ages and geochemistry are presented for igneous rocks from SW Vietnam and S Cambodia. Four main age groupings occur: Cretaceous (107–75 Ma), Early Jurassic (195 Ma), Late Triassic (230–222 Ma), and Permian (294–265 ... -
Peroxide-based route for the synthesis of zinc titanate powder
(Elsevier, 2016)In this work the thermodynamical solubility diagrams of zinc and titanium hydroxides were reviewed in order to determine the conditions for maximum degree of phase composition homogenization of precipitates. Experimental ...
