Using the SAMR Framework, the study examines data from 129 isiXhosa and Afrikaans speakers. Findings reveal that participants found these resources helpful in bridging comprehension gaps, and appreciated their accessibility and simplicity, but raised concerns about translation accuracy. The study emphasises the need for multilingual resources to address language barriers and promote equitable access, contributing to discussions on language policy in education.

There are 1,166 LibGuides hosted by 16 universities, and published by 299 owners in South Africa giving the country a 0.22% of the world's share of LibGuides, and a 0.22% share of the world's LibGuides owners. Each LibGuide owner in the country owns almost four LibGuides. Close to 70% of public universities in South Africa own LibGuides. The University of the Witwatersrand has more LibGuides than any other university followed by the Universities of Cape Town, South Africa, Johannesburg, Stellenbosch, and others. 68.4% of LibGuides in South Africa are faculty and department LibGuides followed by “how to” guides (8.94%). Another finding was that the Ranking Web of Universities correlates moderately with the university rankings by number of LibGuides in the country meaning that LibGuides may play some role in enhancing or at least proving the extent of a university's Web presence and visibility. The views data shows mixed results as North-West University (NWU) views have increased by close to 571% between 2014 and 2015 while those of the Cape Peninsula University of Technology (CPUT) were inconsistent. The combined CPUT and NWU LibGuides cost R0.56 per view, all other factors such as the time and effort it takes to create LibGuides excluded. The results of this study can be used by libraries to demonstrate the value of LibGuides to academic libraries. Therefore, the continued subscription to LibGuides by academic libraries is supported.

These thiol xanthate collectors are conventionally mixed together as well as with more selective thiol collectors such as dithiophosphates (DTP) and dithiocarbamates (DTC), in order to improve selectivity. With deteriorating nickel sulfide ores, more selective collectors and collector mixtures are desired for the efficient extraction of nickel. Thionocarbamates (TC) are another group of thiol collectors used for selective froth flotation of sulfide minerals. Thionocarbamates are especially used in the selective froth flotation of chalcopyrite over pyrite and galena, but little is known about its selectivity with regards to nickel. Thionocarbamates are also more stable over larger pH ranges in comparison to xanthates and they possess beneficial frothing properties. This study compared the effects of using potassium amyl xanthate (PAX), isopropyl ethyl thionocarbamate (IPETC), sodium isobutyl xanthate (SIBX) and their mixtures in the froth flotation of a pentlandite ore. In the mixtures of PAX or SIBX with IPETC, the xanthate accounted for 95.5 mol% and for the PAX and SIBX mixture a 50:50 mixture was used. This study showed that the highest cumulative nickel grades were obtained with PAX, SIBX and there mixture. The highest cumulative nickel recoveries were obtained with IPETC and its mixtures with PAX and SIBX (50–62%). Sun, 01 Jan 2017 00:00:00 GMT http://hdl.handle.net/11189/6283 2017-01-01T00:00:00Z
