Palladium-gold nanoalloy surface modified limn2o4 cathode for enhanced li-ion battery
(Hindawi, 2015)Au with Pd nanoparticles were synthesized and coated onto the spinel LiMn2O4 via a coprecipitation calcination method with the objective to improve the microstructure, conductivity, and electrochemical activities of ... -
Palygorskite hybridized carbon nanocomposite as a high-performance electrocatalyst support for formic acid oxidation
(South African Chemical Institute (SACI), 2013)A nanocomposite, in which acid-treated palygorskite was hybridized with carbon, was prepared and designed as an efficient support for electrocatatlysts. Pd nanoparticles were deposited on the hybrid support as an ... -
A Panel of Ancestry Informative Markers for the Complex Five-Way Admixed South African Coloured Population
(PloS, 2013)Admixture is a well known confounder in genetic association studies. If genome-wide data is not available, as would be the case for candidate gene studies, ancestry informative markers (AIMs) are required in order to adjust ... -
Pansharpened landsat 8 thermal-infrared data for improved land surface temperature characterization in a heterogeneous urban landscape
(Elsevier, 2022)Challenges associated with adolescents are prevalent in South African societies. During the adolescence stage, children may become involved in deviant behaviour. Although a significant number of studies have focused on the ... -
The paracrine effect of hypoxic and normoxic cancer secretion on the proliferation of brain endothelial cells (bend.3)
(MDPI, 2022): Background: This study aimed to investigate the disruption of cell cycle phases of bEnd.3 cells exposed to cancer paracrine secretion. Cancer cells have been reported to use the secretion of paracrine factors to ... -
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 ... -
