Author:Mufhandu, Hazel T; Alexandre, Kabamba B; Gray, ES; Morris, L; Khati, MDate:Sep 2016We have previously shown that the aptamer, UCLA1, is able to inhibit HIV-1 replication in peripheral blood mononuclear cells (PBMCs) by binding to residues in gp120. In this study we examined whether UCLA1 was effective against HIV-1 subtype ...Read more
Author:Perrie, BD; Strauss, PJ; Du Plessis, LDate:Aug 2007Ultra thin continuously reinforced concrete pavements (UTCRCP), in literature also referred to as Ultra Thin Reinforced High Performance Concrete (UTHRHPC), have been used in Europe successfully as a rehabilitation measure on steel bridge ...Read more
Author:Shingange, Katekani; Swart, H; Mhlongo, Gugu HDate:Nov 2019Herein, we report on one-dimensional porous Au-modified LaFeO3 nanobelts (NBs) with high surface area, which were synthesized through the electrospinning method. The incorporation and coverage of Au nanoparticles (NPs) on the surface of the ...Read more
Author:Kekana, Petrus T; Sithole, Bishop B; Ramjugernath, DDate:Feb 2019Ultrafiltration of black liquor was studied in three different modules, namely, radial cross flow, rectangular cross flow and stirred cell over a wide range of operating conditions. Effects of different cut-off membranes on the permeate flux ...Read more
Author:Munonde, Tshimangadzo S; Zheng, Haitao; Nomngongo, PNDate:Dec 2019The oxygen evolution reaction (OER) is an important reaction in water splitting. Nickel-iron layered double hydroxide (NiFe LDH) has been considered a potential catalyst for OER. Herein, we report a simple/green approach to improve the oxygen ...Read more
Author:Smit, MC; Ferreira, JA; Van Wyk, JD; Ehsani, MDate:Jan 1995The concept of an integrated structure for the capacitor, inductor and transformer of the series resonant converters presented. It is shown that the necessary capacitance can be achieved by using a bifilar primary and the leakage inductance ...Read more
Author:Matseke, Mphoma S; Zheng, Haitao; Wang, YDate:Jun 2020Since ultrasonication was reported to be used for exfoliation of layered materials in water (Science-ref. 31), the method has never been explored in non-layered materials, in particular, the effect of ultrasonication on the surface property ...Read more
Author:Oosthuizen, MA; Pretorius, E; Oberholzer, HM; Van der Spuy, WJDate:Oct 2010Engineered nanoparticles are designed to perform specific functions and therefore have specific properties that could potentially be harmful. Nanoparticles such as titanium dioxide have the potential to become transparent and are therefore ...Read more

Author:Thiede, RN; Fabris-Rotelli, IN; Stein, A; Debba, Pravesh; Li, MDate:Nov 2019Informal unpaved roads in developing countries arise naturally through human movement without government authorities being informed. These roads are not authorized nor maintained by council, nor reliably mapped in quality-controlled online ...Read more
Author:Scholes, RJDate:Sep 2002This paper describes a simple, quick, non data-intensive quantitative approach for sorting certain types of environmental issues into those that are unlikely to be problems; those likely to be problems; and those requiring further, more ...Read more
Author:Ramanantsoa, JD; Penven, P; Krug, Marjolaine J; Gula, J; Rouault, MDate:Feb 2018Cruise data sets, satellite remote sensing observations, and model data analyses are combined to highlight the existence of a coastal surface poleward flow in the southwest of Madagascar: the Southwest MAdagascar Coastal Current (SMACC). The ...Read more
Author:Greben, JM; Meyer, R; Kimmie, ZaheedDate:Oct 2011The potential application of MRS technology in locating water bearing fractures in underground mines is studied. The determination of the presence of water ahead of mining is important to prevent accidents and to ensure higher efficiency in ...Read more
Author:Oosthuizen, Dina N; Motaung, DE; Strydom, AM; Swart, HCDate:Jan 2020An approach to tailor the morphology and sensing characteristics of CuO nanoplatelets for selective detection of NO2[sub] gas is of great significance and an important step toward achieving the challenge of improving air quality and in assuring ...Read more
