    Development of molecular tools for honeybee virus research: the South African contribution 

    Davison, Sean; Leat, Neil; Benjeddou, Mongi (Academic Journals, 2003)
    Increasing knowledge of the association of honeybee viruses with other honeybee parasites, primarily the ectoparasitic mite Varroa destructor, and their implication in the mass mortality of honeybee colonies has resulted ...

    Ethics and mono-disciplinarity: positivism, informed consent and informed participation 

    Hersh, Marion A.; Tucker, William David (Elsevier, 2005)
    There are a number of pressures on researchers in academia and industry to behave unethically or compromise their ethical standards, for instance in order to obtain funding or publish frequently. In this paper a case study ...

    Reliable communication across ad hoc networks 

    Daniels, Francois; Tucker, William David (Telkom, 2008)
    This paper presents a fully decentralised peer-topeer voice communication tool intended for use across mobile ad hoc networks (MANET) by distributed groups who desired collaboration. We examined the synergy between MANETs ...

    Policy-based network management of legacy equipment in Next Generation Networks 

    Naidoo, Vaughn; Tucker, William David (Telkom, 2001)
    Next Generation Networks use policy-based network management and QoS protocols to provide voice services on IP networks. Large numbers of older equipment still push IP packets. We present several solutions that include ...

    The effects of long-term exclusion of the limpet Cymbula oculus (Born) on the distribution of intertidal organisms on a rocky shore 

    Maneveldt, Gavin; Eager, Rosemary; Bassier, Aghmat (NISC (Pty) Ltd and Taylor & Francis, 2009)
    Zonation patterns on rocky shores are typically as a result of both physical factors and biological interactions. Physical factors generally set the upper limits of species distributions, while biological interactions ...

    A hydrogeomorphological approach to quantification of groundwater discharge to streams in South Africa 

    Xu, Yongxin; Holness, S.D.; Zhang, J.; van Tonder, Gerrit J. (Water Research Commission, 2002)
    In South Africa, the flow requirements for maintaining the normal functioning of aquatic ecosystems is termed the “ecological reserve”, and these should be determined when a licence application for water allocation is ...

    Comparative analysis of human coronavirus-NL63 ORF3 protein homologues 

    Fielding, Burtram C.; Suliman, Tasnim (Academic Journals, 2009)
    It has been reported in some studies that the newly discovered human coronavirus NL-63 (HCoVNL63) is one of the most common coronaviruses associated with acute respiratory infections. HCoVNL63 was first isolated in 2004 ...
