wastewater treatment and the production of animal feed supplements https://commons.ru.ac.za/vital/access/manager/Repository/vital:3940 90% of the algae population. Under batch operation the population dynamic shifted; Chlorella outcompeted Micractinium possibly due to nutrient depletion and selective grazing pressures caused by proliferation of Daphnia. Higher species diversity was observed during batch mode as slower growing algae were able to establish in the HRAP. Nutrient removal efficiency and biomass productivity was higher in continuous mode, however lower nutrient levels were obtained in batch operation. HMTBA did not significantly affect growth rate, however treatment with 10 mg.L-1 resulted in slightly increased growth rate in Micractinium and increased final biomass concentrations in Chlorella, Micractinium and Spirulina (although this was not statistically significant for Micractinium and Spirulina), which are known mixotrophic species. Algae treated with Cu-HMTBA, showed reduced final biomass concentration with 10 mg.L-1, caused by Cu toxicity. Biochemical composition of the algae was species-specific and differed through the growth cycle, with high protein observed during early growth and high carbohydrate during late growth/early stationary phase. Additionally, 0.1 mg.L-1 HMTBA and Cu-HMTBA significantly reduced protein content in Chlorella, Micractinium, Scenedesmus and Pediastrum. In conclusion, operation of the HRAP in continuous culture provided suitable wastewater treatment with high productivity of an ideal species, Micractinium, for use in animal feed supplementation. This species had 40% protein content during growth (higher than the other species tested) and dominated the HRAP at > 90% of the algae population during continuous mode. Addition of HMTBA (> 1 mg.L-1) to algae cultivation systems and those treating wastewater, has the potential to improve productivity and the value of the biomass by enhancing protein content. Overall, the co-utilisation of microalgae for wastewater treatment and the generation of a biomass rich in protein, for incorporation into formulated animal feed supplements, represents a closed ecosystem which conserves nutrients and regenerates a most valuable resource, water.]]> Wed 12 May 2021 15:55:36 SAST ]]> An investigation into the state-of-practice of information security within Zambian copper mines: a case study https://commons.ru.ac.za/vital/access/manager/Repository/vital:1146 Wed 12 May 2021 15:51:37 SAST ]]> Elephants, compassion, and the largesse of literature https://commons.ru.ac.za/vital/access/manager/Repository/vital:582 Wed 12 May 2021 15:49:42 SAST ]]> Action competence and waste management: a case study of learner agency in two Grahamstown eco-schools https://commons.ru.ac.za/vital/access/manager/Repository/vital:1956 Wed 12 May 2021 15:45:33 SAST ]]> Effect of nanoparticles on the photophysicochemical behaviour of metallophthalocyanines https://commons.ru.ac.za/vital/access/manager/Repository/vital:4310 Tue 24 Aug 2021 16:28:07 SAST ]]> Curating the reviled, beloved and quotidian: a retrospective of Vladimir Tretchikoff https://commons.ru.ac.za/vital/access/manager/Repository/vital:2407 Tue 22 Mar 2022 11:18:04 SAST ]]> "But what story?": a narrative-discursive analysis of "white" Afrikaners' accounts of male involvement in parenthood decision-making https://commons.ru.ac.za/vital/access/manager/Repository/vital:3025 40 years), which were then differentiated according to gender, reproductive status, and relationship status. Treating the interviews as jointly produced narratives, I analysed them by means of a performativity/performance lens. This dual analytic lens focuses on how particular narrative performances are simultaneously shaped by the interview setting and the broader discursive context. The lens was fashioned by synthesising Butler’s theory of performativity with Taylor’s narrative-discursive method. This synthesis (1) allows for Butler’s notion of “performativity” to be supplemented with that of “performance”; (2) provides a concrete analytical strategy in the form of positioning analysis; and (3) draws attention to both the micro politics of the interview conversation and the operation of power on the macro level, including the possibility of making “gender trouble”. The findings of the study suggest that the participants experienced difficulty narrating about male involvement in parenthood decision-making, owing to the taken for granted nature of parenthood for heterosexual adults. This was evident in participants’ sidelining of issues of “deciding” and “planning” and their alternate construal of childbearing as a non-choice, which, significantly served to bolster hetero-patriarchal norms. A central rhetorical tool for accomplishing these purposes was found in the construction of the “sacralised” child. In discursively manoeuvring around the central problematic, the participants ultimately produced a “silence” in the data that repeats the one in the research literature.]]> Tue 15 Aug 2023 16:06:17
