Author:Vaid, A; Ranjan, R; Verma, G; Smythe, WA; Hoppe, HC; Sharma, PDate:Mar 2010phosphorylated phosphoinositides (PIPs) are potent second messengers, which trigger a wide variety of signaling and trafficking events in most eukaryotic cells. However, the role and metabolism of PIPs in malaria parasite Plasmodium have ...Read more
Author:Reynolds, QG; Olsen, JE; Erwee, MW; Oxtoby, Oliver FDate:Jun 2019The extraction of molten products and wastes through smelting furnace tap-holes during the tapping process is a complex procedure involving many coupled thermophysical effects. Insight into the fluid flow behaviour in such systems can be ...Read more
Author:Simo, A; Kaviyarasu, K; Mwakikunga, Bonex W; Madjoe, R; Gibaud, A; Maaza, MDate:Apr 2017Intermediate phase monoclinic M2 was observed by inducing in situ X-ray thermo diffraction on VO2 (M) nanoplatelets. The solid-solid phase transition occurs at around 65 °C assisted with the percolative transition metal-insulator. The existence ...Read more
Author:Zerbian, S; Barnard, EDate:2008Much is already known about the prosodic systems of the indigenous South African languages from descriptions and analyses in the existing literature. All of the existing work has been carried out in the field of African studies or formal ...Read more
Author:Peche, M; Davel, MH; Barnard, EDate:Aug 2007The authors investigate the addition of a new language, for which limited resources are available, to a phonotactic language identification system. Two classes of approaches are studied: in the first class, only existing phonetic recognizers ...Read more
Author:De Koning, AJDate:Sep 2005Fillets 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 contributes to their ...Read more
Author:Owen, GR; Stoychev, Stoyan H; Achilonu, I; Dirr, HWDate:Oct 2014Many studies have characterized how changes to the stability and internal motions of a protein during activation can contribute to their catalytic function, even when structural changes cannot be observed. Here, unfolding studies and ...Read more

More specifically, analysis by X-ray diffraction and ...Read more
Author:Chakraborty, AK; Ganguli, S; Kebede, Mesfin ADate:Jun 2012Single crystalline MnWO4 nanorod has been prepared by low temperature hydrothermal reaction at 180 °C. The prepared MnWO4 possesses band gap of 2.63 eV. Photochemical decomposition method has been followed to disperse Au nanoparticles onto ...Read more
Author:Ama, Monday O; Wilson, AW; Ray, Suprakas SDate:Aug 2019The present study reports the application of three electrodes, consisting of exfoliated graphite (EG), EG and zirconium oxide (EG-ZrO2), and EG and silver-doped zirconium oxide (EG/Ag-ZrO2) in a comparative photoelectrochemical degradation ...Read more
Author:Sikhwivhilu, LM; Mpelane, S; Mwakikunga, Bonex W; Ray, Suprakas SDate:Mar 2012Titanium dioxide (TiO2) nanostructures were synthesized by microwave-assisted and conventionally heated hydrothermal treatment of TiO2 powder. The tubular structures were converted to a rodlike shape by sintering the samples at various ...Read more
Author:Kabongo, GL; Mbule, PS; Mhlongo, Gugu H; Mothudi, BM; Hillie, Kenneth T; Dhlamini, MSDate:Dec 2016In this article, we demonstrate the surface effect and optoelectronic properties of holmium (Ho(sup3+))-doped ZnO in P3HT polymer nanocomposite. We incorporated ZnO:Ho(sup3+) (0.5 mol% Ho) nanostructures in the pristine P3HT-conjugated polymer ...Read more
Author:Bollig, C; Forbes, A; Dlamini, TDate:Dec 2007This document gives an overview of the development of photonics in South Africa. The development of science, engineering and technology (SET) has been identified as one of the key elements for the long-term sustainability and competitiveness ...Read more
Author:Mthunzi-Kufa, Patience; Dholakia, K; Gunn-Moore, FDate:Jul 2010Recently, femtosecond laser pulses have been utilized for the targeted introduction of genetic matter into mammalian cells.
