  • Description: Microbial water quality is an essential aspect in the provision of potable water for domestic use. The provision of adequate amounts of safe water for domestic purposes has become difficult for most municipalities mandated to do so in Zimbabwe. Morton-Jaffray Treatment Plant supplies potable water to Harare City and areas surrounding Harare. This study investigated microbial water quality and the impact of microbial water quality related disasters in the area supplied by the Morton Jaffray Treatment Plant. Questionnaires were distributed to household owners in Harare who receive their water from the Municipality and those who use alternate water supplies. Candidates were randomly selected from their workplace. The raw water quality of Manyame River and its tributaries was assessed. Treated water in households was assessed for microbial quality using hydrogen sulphide test and heterotrophic bacteria plate count. Raw water sources were found to be contaminated by faecal matter. Household water sources tested negative for faecal contamination but positive for heterotrophic bacteria. CFU quantities ranged from 1 to 452 CFU/m. for all samples. The WHO guidelines for domestic water sources state that water used for domestic purposes should not be contain than 100 CFU/m.. Public perceptions of water quality ranged from eunsafef to ehighly contaminatedf. A decrease in the level of aesthetic appeal resulted in residents resorting to alternative sources such as wells and rivers for their domestic water. The current state of treated water was suitable for domestic use. Pathogen monitoring of domestic water is recommended using the hydrogen sulphide test and R2A agar test.

  • Description: In July 1946, the fledgling Council for Scientific and Industrial Research (CSIR) awarded Dr J.L.B. (James Leonard Brierley) Smith of Rhodes University College a research fellowship of £800 to enable him to devote his energies to ichthyology. The university responded by providing accommodation, equipment and appointing Smith a research professor. These actions marked the beginning of what has become a major academic development in Grahamstown as represented by the J.L.B. Smith Institute of Ichthyology, the Department of Ichthyology and Fisheries Science (DIFS), and the Freshwater Fish Section at the Albany Museum. At present more than 40 people are employed in one way or other in these organizations, more than 20 of them professionals, in addition to whom there are 41 postgraduate students currently studying ichthyology or fisheries science through DIFS at Rhodes University. Altogether this represents a concentration of ichthyological expertise probably unmatched anywhere else in the world. It is opportune therefore to highlight a few of the more significant milestones in the history of ichthyology in Grahamstown and so illuminate some of the key factors behind this achievement.

  • Description: Biological sulph ate reduction has been identi fied as a potentially valuable process for removing sulphate and heavy metals from indllstrial effluents. The role of sulphate reducing bacteria (SRB) in this process has attracted the attention of biotechnologists and recently of enzymologists due to its fundamental properties and possible role in AMD bioremediation. These obligatory anaerobic sulphate-reducing bacteria are commonly known to dissimilate sulphate for energy. Under anaerobic conditions SRB oxidize simple organic compounds such as lactic acid with the sulphate and thereby generate hydrogen sulphide (a stTong reducing agent) and bicarbonate ions. The hydrogen sulphide in turn reacts with contaminant metals contained in AMD and precipitates them out of solution as metal sulphides. Bicarbonate ions neutralize AMD by reaction with protons to form carbon dioxide and water. Organic matter in the municipal sewage sludge has been identified as a potential source of electron donors for su lphate reduction. However, this organic matter is in the polymeric form that cannot be util ised by SRB. The latter depend on the activities of other hydrolytic bacteria for the degradation of complex polymers. Hence the availability of these monomeric substrates is a major factor, which may constrain further process development and is considered a rate-limiting step. Thi s study is therefore undertaken to investigate the bacterial glucohydrolase enzymes involved in the digestion of the polysaccharides present in the sewage sludge with specific interest in cellulases and/or p-glucosidase enzymes. The goals of the research are to: isolate, identify, purify and quantify these enzymes; study their distribution with respect to time, pH, and temperature; maximize and quantify the hydrol ys is products; study whether sulphide and sulphate have an enhancing or an inhibitory effect on the activity of enzymes; optimize the enzyme activity against substrate and/or product inhibition and soluble heavy metal salts. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

  • Description: Hip-hop is frequently linked to misogyny and other forms of violence. This link, in many instances, is often presented outside of a critical understanding of complex underlying societal and gender dynamics. South Africa’s high rates of violence against women make it necessary to understand how hip-hop videos interact with society, as hip-hop, in its commercial form, has become a growing music genre in South Africa. Rhodes University, which has a notable student following of hip-hop, has experienced concerning levels of gender-based tensions as evidenced by the rise of the “fallist” movement’s #RapeCultureMustFall, #RUReferenceList and the suicide of Khensani Maseko, at the instigation of an alleged incident of rape, perpetrated by her boyfriend and fellow student. It is therefore of interest to investigate how a select group of Rhodes University student-fans of hip-hop make meaning out of selected South African commercial hip-hop music videos. The hip-hop music videos chosen for the study, hence Pitbull Terrier (Die Antwoord), Pearl Thusi (Emtee), Dlala ka yona (L’Tido), All eyes on me (AKA featuring Burna Boy, Da L.E.S and JR) and Ragga Ragga (Gemini Major featuring Casper Nyovest, Riky Rick and Nadia Nakai), were selected on the strength of their popularity and uniquely gendered scenarios. This study draws on qualitative research methods, thus qualitative thematic content analysis, focus group and in-depth interviews. The study establishes that despite gender being a contentious issue at Rhodes University, students make meaning out of the gendered portrayals based on their own experiences, socialisation, cultural values and level of submission to the discourse of hip-hop. This study seeks to understand how selected student-fans of hip-hop read the gendered portrayals of the music videos, based on their own experiences, socialisation, cultural values, and level of submission to the discourse of hip-hop.

  • Description: Patterns of genetic structure and connectivity of the monotypic cigar wrasse Cheilio inermis within western Indian Ocean (WIO) are poorly understood. Whether the species exists as a single panmictic population across the WIO is unclear. Sequence data were generated from two mitochondrial genes (cytochrome b and ATPase 6) and one nuclear intron (S7 intron I). High levels of haplotype and allelic diversity (h = 0.88–0.98; A = 0.95–0.98), along with low nucleotide diversities were observed across all markers.

  • Description: The exhibition catalogue Rise and Fall of Apartheid is a valuable collection of photographic images that create, according to Enwezor, “a critical visualization and interrogation of […] [apartheid’s] normative symbols, signs and representation” (18). The catalogue focuses on African subjects as “agents of their own emancipation” (18), and contextualises South Africa’s anticipation of the end of apartheid within broader global changes in the late 1980s. Essays by Okwui Enwezor, Michael Godby, Achille Mbembe, Darren Newbury, Colin Richards, Patricia Hayes, Andries Walter Olifant, Rory Bester and Khwezi Gule are included in the catalogue, and are interspersed between photographic images that are grouped in chronological clusters: 1948–1959; 1960–1969; 1970–1979; 1980–1989; and 1990–1995.

  • Description: Adolescent pregnancy among students across South Africa is a growing concern. The high incidence of dropping out of school results in greatly diminished chances of success and independence for many. Sex education forms part of the life orientation curriculum, and it has been put in place by the Department of Education as a measure to reduce the prevalence of adolescent pregnancy. Parents of adolescents play a vital role in educating their children on sexual matters, secondary to that is community educations on sexual matters in aid of uplifting communities. The aim of the study was to explore the perception of how effective sex education could be a means of reducing pregnancies in the Blue Crane Route Municipality. To achieve this aim, three objectives and three research questions were articulated. The objectives were to explore the course content of life orientation provided to adolescents, to investigate by questioning adolescents concerning the importance of life orientation in their lives and to examine the factors responsible for the escalation of adolescent pregnancies in the municipality. The research questions were: How adequate was the course content of life orientation in helping adolescents in their sexual lives? How useful was life orientation to adolescent girls? What are the factors that increase the incidence of adolescent pregnancies in the municipality? Qualitative data was obtained through semi-structured interviews; focus group discussions were conducted with students, social workers and life orientation educators and observations made by them were recorded. Data was analysed thematically and was supported by relevant literature. The findings revealed that sex education is not effective in reducing pregnancies in the Blue Crane Route Municipality. The figures for adolescent pregnancy in schools have increased since 2007, when sex education was introduced as part of the life orientation curriculum. Accordingly, it is recommended that the Department of Education should re-evaluate the curriculum and appoint educators who are sufficiently trained in life orientation to make learners properly aware of the consequences of unwanted pregnancies.
