  • Kilkenny, David; Welsh, B.Y.; Koen, Chris; Gulbis, A.A.S.; Kotze, M.M. (Oxford University Press, 2014)
    We present high-speed photometry (resolution 0.1 s) obtained during the commissioning of the Berkely Visible Imaging Tube system on the Southern African Large Telescope (SALT). The observations were an attempt to search ...
  • Burton, Stephanie; Cowan, Donald A.; Woodley, John M. (Nature Publishing Group, 2002)
    While the use of enzymes as biocatalysts to assist in the industrial manufacture of fine chemicals and pharmaceuticals has enormous potential, application is frequently limited by evolution-led catalyst traits. The advent ...
  • Ikalafeng, B.K.; Pool, E.J.; Lues, R.; Groenewald, W.H. (Academic Journals, 2013)
    A seasonal study on citrinin concentrations in traditional beer was conducted using a standardised enzyme-linked immunosorbent assay. Representative samples of indigenous South African beer were collected during the hot, ...
  • Amado-Filho, Gilberto M.; Maneveldt, Gavin; Pereira-Filho, G.H.; Manso, R.C.C.; Bahia, Ricardo (Universidad Autónoma de Baja California, 2010)
    This study describes the predominantly tropical, subtidal seaweed populations growing on rhodoliths between 4 and 18 m depth in the southern part of Espírito Santo State (Brazil). Qualitative and quantitative sampling ...
  • Poroye, Adeola; Tucker, William David; Norman, Michael (Telkom, 2009)
    This paper presents work in progress to explore the utility of Near Field Communication technology to secure mobile financial services. The objective is to evaluate the potential of this approach as an upcoming technology ...
  • Mauwa, H.; Tucker, William David (Telkom, 2013)
    Wireless Mesh Networks can provide low cost and reliable community-owned connectivity in developing rural areas. A rural community can use mesh networks to access a wide range of modern information and communication ...
  • Wang, Rongfang; Da, Huahua; Wang, Hui; Ji, Shan; Tian, Zhongqun (Elsevier, 2013)
    Using selenium functionalized carbon as supports, platinumeruthenium nanoparticles were highly dispersed on the carbon surface, and showed improved electrochemical properties for methanol electrooxidation. The method ...
  • Fadhal, Emad; Gamieldien, Junaid; Mwambene, Eric (2015)
    The successful determination of reliable protein interaction networks (PINs) in several species in the post-genomic era has hitherto facilitated the quest to understanding systems and structural properties of such networks. ...
  • Pagaling, Eulyn; Haigh, Richard D.; Grant, William D.; Cowan, Donald A.; Jones, Brian; Ma, Yanhe; Ventosa, Antonio; Heaphy, Shaun (BioMed Central, 2007)
    Background: We are profoundly ignorant about the diversity of viruses that infect the domain Archaea. Less than 100 have been identified and described and very few of these have had their genomic sequences determined. ...
  • Bheekie, Angeni; Obikeze, Kenechukwu; Bapoo, Rafik; Ebrahim, Naushaad (Academic Journals, 2011)
    High patient load and understaffing in public health care facilities preclude the provision of optimal pharmaceutical services in South Africa. A Service Learning in Pharmacy (SLIP) programme for the University of the ...

    Here we analyzed the gene expression profile of cells that stably express the severe acute respiratory syndrome coronavirus (SARS-CoV) 3a protein to determine its effects on host functions. A lung epithelial cell-line, ...
  • Fielding, Burtram C.; Gunalan, Vithiagaran; Tan, Timothy H.P.; Chou, Chih-Fong; Shen, Shuo; Khan, Sehaam; Lim, Seng Gee; Hong, Wanjin; Tan, Yee-Joo (Elsevier, 2006)
    Severe acute respiratory syndrome coronavirus (SARS-CoV) 7a is an accessory protein with no known homologues. In this study, we report the interaction of a SARS-CoV 7a and small glutamine-rich tetratricopeptide repeat-containing ...
  • Motlhabi, Michael B.; Glaser, Meryl; Tucker, William David (Telkom, 2013)
    This paper discusses a prototype for a communication aid on a mobile phone to support a Deaf1 person visiting a public hospital pharmacy. The aim is to prevent problems of non-compliance to treatment due to poor communication ...
  • Koen, Chris; D’Amato, M.E. (Elsevier, 2010)
    The non-recombining nature of the Y-chromosome determines the non-independence of alleles between loci. The evolution of short tandem repeat (STR) loci in the Y-chromosome is the result of different factors such as ...
  • Wu, Wilson; Radovanovic, Aleksandar; Tucker, William David (Telkom, 2005)
    This paper presents an innovative use of the Session Initiation Protocol (SIP) for the subscription and notification of geographic information in order to provide a privacy concerned location-based service. SIP is a signaling ...
