  • Mathe, Mahlanyane K; Cox, SM; Venkatasamy, V; Happek, U; Stickney, JL (Electrochemical Society, 2005-09)
    The growth of HgSe using electrochemical atomic-layer epitaxy (EC-ALE) is reported. EC-ALE is the electrochemical analog of ALE, where electrochemical surface-limited reactions referred to as underpotential deposits, ...
  • De Koning, AJ (Acad Science South Africa A S S AF, 2005-09)
    Fillets of deep-skinned orange roughy (Hoplostethus atlanticus) were found to contain 5.46% total lipids consisting of as much as 93% non-digestible wax esters. The fillets therefore act as a mild laxative, which probably ...
  • Fedotov, I; Katskov, D; Shatalov, MY; Marais, J (Springer Science, 2006)
    A one-dimensional model is developed to describe atomic diffusion in a graphite tube atomizer for electrothermal atomic adsorption spectrometry. The underlying idea of the model is the solution of an inhomogeneous ...
  • De Koning, AJ (Academy of Science South Africa (ASSAF), 2006-01)
    Muscle of rudderfish (centrolophus niger), or black ruff, a rare mesopelagic fish caught in the South Atlantic, was found to contain 19.3% total lipids. The major part of the lipids (~70%) was unusual in not yielding ...
  • Polderijk, JJ; Van Dyk, FE; Ferreira, D; Guis, GW; Keller, S (Springer, 2006-03)
    South-African and Dutch research institutes and business partners collaborated in several pilot projects for improving logistical performance and quality performance to strengthen the market position of South-African fruit ...
  • Venkatasamy, V; Jayaraju, N; Cox, SM; Thambidurai, C; Mathe, Mahlanyane K; Stickney, LJ (Electrochemical Society, 2006-04)
    This paper describes the first instance of HgTe growth by electrochemical atomic layer epitaxy (EC-ALE). EC-ALE is the electrochemical analog of atomic layer epitaxy (ALE) and atomic layer deposition (ALD), all of which ...
  • Venkatasamy, V; Mathe, Mahlanyane K; Cox, SM; Happek, U; Stickney, JL (Elsevier, 2006-06)
    Studies of the optimization of HgSe thin film deposition using electrochemical atomic layer epitaxy (EC-ALE) are reported. Cyclic voltammetry was used to obtain approximate deposition potentials for each element. These ...
  • Gardiner, NS; Lalloo, Rajesh; Ramduth, DM; Dudas, J; Marcus, M (2006-09)
    Oral presentation on commercial implementation of β-carotene at the Bio2Biz Conference
  • Buddoo, SR (2006-10)
    The research project aimed at developing a cost-effective process to produce citral and citronellal. Microreactor technology was also applied to some of the reaction steps as a more efficient and inexpensive alternative ...
  • Steenkamp, PA; Harding, NM; Van Heerden, FR; Van Wyk, BE (Elsevier Ireland Ltd, 2006-11)
    An LC-MS screening method was developed to detect the presence of atractyloside (ATR), the toxic principle of a commonly used medicinal plant in South Africa, Callilepis laureola, in biological matrices such as body fluids ...
  • O'Kennedy, Maretha M; Grootboom, A; Shewry, PR (Elsevier Science Ltd, 2006-11)
    This review highlights recombinant DNA technology as a powerful tool to enhance the gene pools of sorghum and pearl millet crops regarded as jewels of Africa. Although important advances in the improvement of these species ...
  • Byaruhanga, YB; Erasmus, C; Taylor, JRN; Emmambux, MN (John Wiley & Sons Ltd, 2007-01)
    Edible films can be produced from kafirin but the diverse food product requirements necessitate modification of the films. To modify their functional properties, kafirin films were cast, with and without plasticizer, from ...
  • Erasmus, C; Jacobs, A; Lombard, GE; Van Zyl, PJ; Reddy, JS; Nkomo, N; Timme, EM (2007-01)
    Development of fermentation process for EPA production: The effect of fungal growth conditions on morphology and EPA production. Fungal pellets in submerged culture vary in size, texture and shape: from ellipsoidal ball ...
  • Rashamuse, KJ; Burton, SG; Stanfford, WHL; Cowan, DA (2007-02)
    An esterase producing Burkholderia multivorans UWC10 strain was isolated by culture enrichment. A shotgun library of B. multivorans UWC10 genomic DNA was screened for esterase activity and a recombinant clone conferring ...
  • Kostinek, M; Specht, I; Edward, VA; Pinto, C; Egounlety, M; Sossa, C; Mbugua, S; Dortu, C; Thonart, P; Taljaard, L; Mengu, M; Franz, CMAP; Holzapfel, WH (Elsevier B.V, 2007-03)
    A total of 375 lactic acid bacteria were isolated from fermenting cassava in South Africa, Benin, Kenya and Germany, and were characterised by phenotypic and genotypic tests. These could be divided into five main groups ...
  • Van Heerden, FR; Horak, RM; Maharaj, VJ; Vleggaar, R; Senabe, JV; Gunning, PJ (Pergamon-Elsevier Science Ltd, 2007-04)
    Two new pregnane glycosides were isolated by fractionation of the dried stems of Hoodia gordonii. Their structures were determined as 3beta-[beta-D-thevetopyranosyl-(1→4)-beta-D-cymaropyranosyl-(1→4)-beta-D-cymaropyranos ...
  • Pinches, SE; Apps, P (Elsevier B.V, 2007-05)
    The ability of two strains of Trichoderma, isolated from food, to produce the Volatile Organic Compounds 1,3-pentadiene and styrene was investigated. One of the strains had been implicated in a case of food spoilage involving ...
  • Shatalov, M; Fedotov, I (Austral Internet Publishing, 2007-08)
    In this paper the authors present a new method of numerical evaluation of unknown coefficients of a dynamical system having available information about unknown phase trajectories at some time values. The method consists ...
  • Van Der Merwe, A; Van Dyk, E; Van Vuuren, J (Operations Research Society of South Africa (ORSSA) and Operations Research practice in Africa (ORPA), 2007-09)
    The goal of the study is to lend decision support to management a a wine cellar in three areas of expertise, with Wamakersvallei Winery serving as a special case study. This decision support system is to be delivered in ...
