Closure, interior and neighbourhood in a category
(Hacettepe University, 2018)The natural correspondences in topology between closure, interior and neighbourhood no longer hold in an abstract categorical setting where subobject lattices are not necessarily Boolean algebras. We analyse three ... -
A cluster analysis of peer support training needs for foster parents
(Springer, 2021)Peer volunteers provide valuable support to foster parents. However, there has been limited research on what they consider to be valuable preparation for the role. In the present study, they were asked: “What is essential ... -
Cluster foster care: a panacea for the care of children in the era of HIV/Aids or an MCQ?
(Stellenbosch University (SUNJournals), 2010)The ravages wrought by HIV/AIDS on child-care arrangements in the African context are well documented (Richter & Sherr, 2009; Sloth-Nielsen & Mezmur, 2008; Tsegaye, 2007; sources cited there). Notably, these constitute ... -
Clustered data muling in the internet of things in motion
(MDPI, 2019)This paper considers a case where an Unmanned Aerial Vehicle (UAV) is used to monitor an area of interest. The UAV is assisted by a Sensor Network (SN), which is deployed in the area such as a smart city or smart village. ... -
Clustered Multi-layer Multi-protocol Wireless Mesh Networks
(Telkom, 2015)Wireless Mesh Networks (WMNs) have emerged as an alternative option to the wired networks in areas where wired deployment is unfeasible and/or costly. They have been widely adopted in community networks as these networks ... -
Clustering of HI galaxies in the HI parkes all sky survey and arecibo legacy fast alfa survey
(Oxford University Press, 2011)We investigate the clustering of H I-selected galaxies in the Arecibo Legacy Fast ALFA Survey (ALFALFA) and compare results with those obtained for the H I Parkes All Sky Survey (HIPASS). Measurements of the angular ... -
Clustering of quintessence on horizon scales and its imprint on HI intensity mapping
(IOP Science, 2013)Quintessence can cluster only on horizon scales. What is the effect on the observed matter distribution? To answer this, we need a relativistic approach that goes beyond the standard Newtonian calculation and deals properly ... -
CNx-modified Fe3O4 as Pt nanoparticle support for the oxygen reduction reaction
(Springer, 2013)A novel electrocatalyst support material, nitrogendoped carbon (CNx)-modified Fe3O4 (Fe3O4-CNx), was synthesized through carbonizing a polypyrrole-Fe3O4 hybridized precursor. Subsequently, Fe3O4-CNx-supported Pt (Pt/Fe3O4-CNx) ... -

Co-pelletization of a zirconium-based metal-organic framework (UiO-66) with polymer nanofibers for improved useable capacity in hydrogen storage
(Elsevier, 2021)We report on a concept of co-pelletization using mechanically robust hydroxylated UiO-66 to develop a metal-organic framework (MOF) monolith that contains 5 wt% electrospun polymer nanofibers, and consists of an architecture ... -
