    The peculiar motion of galaxies can be a particularly sensitive probe of gravitational collapse. As such, it can be used to measure the dynamics of dark matter and dark energy as well the nature of the gravitational laws ...
  • Appunni, Sathiya Susuman (WB Saunders, 2011)
    Summary: Objectives: Examine the mental health issues in Ethiopia in relation to services offered in this direction. Study Design: Retrospective. Methods: Results of the 2005 Ethiopian Demographic and Health Survey and ...
  • Cowan, Donald A.; Arslanoglu, A.; Burton, Stephanie; Cameron, Rory A.; Baker, Gillian; Smith, Jacques J.; Meyer, Quinton (Portland Press, 2004)
    With the rapid development of powerful protein evolution and enzyme-screening technologies, there is a growing belief that optimum conditions for biotransformation processes can be established without the constraints of ...
  • Applebaum, P.C.; Moodley, J.; Chatterton, S.A.; Cowan, D.B.; Africa, Charlene W.J. (Health and Medical Publishing Group, 1978)
    The influence of prophylactic metronidazole on vaginal carriage rates of anaerobes and the development of postoperative anaerobic infection was studied in 104 women who underwent abdominal hysterectomy. Metronidazole ...

    Using the two largest collections of Mus musculus and Homo sapiens transcription start sites (TSSs) determined based on CAGE tags, ditags, full-length cDNAs, and other transcript data, we describe the compositional landscape ...
  • Africa, Charlene W.J. (InTech, 2012)
    Introduction: The study of the aetiology of periodontal diseases has continued for decades with much progress shown in the last two decades. Having moved through periods of “whole” plaque (with emphasis on mass) being ...
  • Gokul, Jarishma K.; Valverde, Angel; Tuffin, Marla; Cary, Stephen Craig; Cowan, Don A. (Multidisciplinary Digital Publishing Institute (MDPI), 2013)
    The discovery of extensive and complex hypolithic communities in both cold and hot deserts has raised many questions regarding their ecology, biodiversity and relevance in terms of regional productivity. However, most ...
  • Chininthorn, Prangnat; Glaser, Meryl; Freudenthal, Adinda; Tucker, William David (IIMC International Information Management Corporation, 2012)
    This paper presents a case for iterative community-based co-design to facilitate the emergence of an innovative mobile system to address a potentially life-threatening scenario for Deaf people in South Africa. For Deaf ...
  • Mutemwa, Muyowa; Tucker, William David (Telkom, 2010)
    This paper describes how a deaf to hearing communication aid built for a mobile phone can be used to provide semi-synchronous communication between a Deaf person and a hearing person who cannot sign. Deaf people with access ...

  • Zhao, Gong-Bo; Bacon, David; Maartens, Roy; Santos, Mario G.; Raccanelli, Alvise (Proceedings of Science, 2014)
    Employing a nonparametric approach of the principal component analysis (PCA), we forecast the future constraint on the equation of state w(z) of dark energy, and on the effective Newton constant m(k; z), which parameterise ...
  • Neethling, Simone; Channing, Alan; Gershwin, Lisa-Ann; Gibbons, Mark J. (Cambridge University Press, 2011)
    A new record of Crambionella stuhlmanni is reported from the east coast of South Africa. The material is described using quantitative morphological data, and mitochondrial (CO1) and nuclear (ITS-1) sequence data. The species ...
