Author:Mutombo, K; Siyasiya, C; Stumpf, WDate:Jul 2015The ß-phase transforms to a', a and a" within a range of temperature from the ß-transus (Tß) to about 600oC, considering no external stress is applied. Two types of microstructure were obtained: acicular martensite when rapidly cooled and ...Read more
Author:Nxumalo, S; Chikwanda, HK; Machio, Christopher NDate:Oct 2010A TiPt alloy was produced by mechanically alloying the desired quantities of titanium and platinum. The resultant TiPt alloy powder was cold pressed to produce green bodies. Several sintering conditions were used to sinter this alloy. It was ...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:Grobler, MMDate:Aug 2010Phishing is an attempt by a third party to solicit confidential information from an individual, group or organization. Phishers attempt to trick users into disclosing personal data, such as credit card numbers, online banking credentials and ...Read more
Author:Van Niekerk, DR; Barnard, EDate:Sep 2009The rapid development of concatenative speech synthesis systems in resource scarce languages requires an efficient and accurate solution with regard to automated phonetic alignment. However, in this context corpora are often minimally designed ...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:Savage, WHDDate:1961In the progress report for the period October 1960 to February 1961 (FRI Technical memo 2/1961) certain phosphorus contents of Waterberg coal samples were reported. It was decided that further investigations be undertaken, with particular ...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
Author:Mthunzi-Kufa, Patience; Gunn-Moore, F; Dholakia, KDate:Sep 2010Due to their self-renewal and pluripotency characteristics, stem cells possess the potential to dramatically advance current therapies in tissue regeneration and engineering. In this work, we report for the first time that femtosecond laser ...Read more
Author:Mthunzi-Kufa, Patience; Gunn-Moore, FJ; Dholakia, KDate:Jun 2009Various methods including chemical, viral or physical approaches have been developed to trigger transient membrane permeabilisation with limited cytotocixity in cells. Such developments permit efficient cytoplasmic delivery of genes, ...Read more
