- Description: Only limited information is available in the literature on the role of soil mineral surfaces in the sorption of hydrophobic organic pollutants. This knowledge gap is addressed through the assessment of biphenyl sorption to kaolinite, illite and bentonite; using the batch equilibration technique with incubations lasting 6 or 21 days at 28 ± 2°C in the dark [RT1]. Sorption of biphenyl onto kaolinite followed the Freundlich sorption isotherm, whereas linear sorption isotherms were observed on illite and bentonite [RT2]. The biphenyl sorption partition coefficient on kaolinite ranged from 0.1 to 9.1 cm3.g-1 after 6 days and no sorption was observed after 21 days. This could have been caused by a completely reversible sorption or a loss of binding capacity after 21 days [RT3]. The respective values of the biphenyl sorption partition coefficient on illite and bentonite ranged from 20.3 ± 0.3 to 120 ± 8 cm3.g-1.Sorption equilibrium on the internal clay surfaces was reached after 6 days, as indicated by the sorption data for illite and bentonite [RT4]. Access of biphenyl molecules to the internal clay surfaces is a function of the ionic strength of soil solution and the soil organic matter is the dominant site for biphenyl sorption after 6 to 21 days.

- Description: South African literature has never been particularly perceptive in addressing the question of race. While this is especially true of writing of the apartheid period, not much has changed in the postapartheid years. Only rarely does one encounter a literary treatment of race that is aware of its performative, rather than essential, nature. Rarer still are works that are conscious of the ways in which we gain a sense of belonging by shaping our environments to affirm our raced subjectives.

- Description: The aim of the government' s state of emergency in June 1986 was to try and bring the country under control through the use of force. Tens of thousands of people were detained, and many were tilled. At the same time, the government has been building a National Security Management System (NSMS). This is a series of structures throughout South Africa, designed to defend apartheid. The main type of structure is called a Joint Management Centre (JHC). Before we explain what a JMC is and what it does, it is useful to know where the idea for a National Security Management System comes from.

- Description: The wage talks are resuming on May 8th 2001. At the time of going to print, all provinces were holding marches all over the country to highlight our demands for a living wage. Currently on the table is a proposal by the conciliator that all parties should agree to accept an 8% across the board increase, and an increase in the minimum wage to R1900. Firstly this proposal has not yet been accepted by the employer. At the conciliation, the employer stuck to 5% only. Secondly this falls short of our demand. It means we will not get the R300 across the board. Any worker earning below R3800 per month is going to get an increase of less than R300. The hardest hit will be workers earning from R1700 - R3000 who will only get R136 - R240. There is nothing more we can get from conciliation or negotiations. It is now up to YOU the workers to decide if you will accept the 8% offer put on the table by the conciliator!

- Description: It is sad how the promises of a better life for all made by the government means so little for workers. Cosatu and Samwu mobilised our forces to ensure a victory for the ANC in the national and local government elections. Despite the fact that workers have put MPs into parliament and councillors into local government councils, we have yet to see any real benefit for workers. The 3rd and final round of negotiations delivered a big disappointment for Samwu. Once again we went into negotiations with high hopes of persuading Saiga to implement decent wage increases. Samwu’s position of R250 or 10% for workers earning less than R6 700 per month was very reasonable. Because we said that those earning more than R13 700 should get a 7% increase, this meant that the total cost to councils was only 9%, which is very affordable. Saiga moved its position in negotiations by 1%. They also tried to get us to give up our demand for a R250 increase by offering a minimum wage of R1600. As we know, most workers are earning more than that. Workers earning R1600 Saiga's 5% will mean a R80 increase. This is less than councillor's get for attending one meeting! Although the negotiators tried everything to try to reach a settlement, Saiga frustrated us at every turn.

- Description: Cyclodextrins (CDs) have widely been used as component of drug delivery systems. However unmodified cyclodextrins are associated with cytotoxicity and poor water solubility thus limiting their use in pharmaceutical industry. The cationic-β-cyclodextrin (Cat-β-CD) polymer cores were synthesized using β-CD, epichlorohydrin and choline chloride via a one-step polycondensation process. The main aim of this study was to synthesize hierarchical nanoflowers composed of cationic-β-CD as polymeric core along with alginate and chitosan “petals” (Cat-β-CD/Alg-Chi nanoflowers) as carriers for oral delivery of 5-Fluorouracil (5-FU) via an ionic-gelation technique. The drug loading capacity, particle size, zeta potential and surface morphology of the synthesized nanoflowers were determined. The prepared nanoflowers were formed with an average size of 300 nm and a zeta potential of + 9.90 mV with good encapsulation efficiency of up to 77.3%. In vitro release of 5-FU from the loaded nanoflowers showed controlled and sustained release compared to the inclusion complex alone. Cat-β-CD/Alg-Chi nanoflowers were assessed against L929 cells and found to be effectively inhibiting the growth of L929 cells in a concentration dependent manner.

Cde Gumede outlined the purposes of the conference “to assess progress and problems, to plan our path in order to provide a clear programme towards centralised bargaining as a result of proper analysis”, He urged delegates “to push employers into joint employers forums to negotiate on proper wages, job creation and an end to retrenchments”. Cde Jay Naidoo addressed the conference on the burning issues of the day. He spoke about VAT, the National Economic Negotiating Forum, trade union unity and CODESA. Cde Naidoo stressed that future economic and political policies must be formulated on the basis of daily and immediate issues facing the working people. Acting General Secretary, Cde Muzi Buthelezi outlined the progress made in the struggle for centralised bargaining. “We have to note” he said, “that the chemical bosses are very tough on this question. They do not want to negotiate, meet or do anything as an industry. They want to keep all activities at a plant or company level”. The remainder of the conference was given the task of redefining the sectors within the chemical industry, developing core demands and outlining a programme of action. Delegates broke into their different sectors to discuss these issues before returning to plenary to thrash out the major steps to be taken by the union in the coming months.

- Description: This article contends that Zimbabwe’s agency in its engagement with China has been limited and at best circumscribed. This owes to factors such as indifference by state authorities to cooperation with civil society actors in negotiating with Chinese actors, the desperation of the The Zimbabwe African National Union – Patriotic Front regime in the face of isolation by erstwhile partners as well as the opacity and secrecy that characterizes significant areas of the Zimbabwe–China relationship. The pressing need for critical institutions such as parliament to play independent oversight roles as well as the creation of space for civil society watchdog functions are highlighted as key enablers if Zimbabwean agency is to generate positive gains from the country’s engagement with China.

- Description: This article contends that Zimbabwe’s agency in its engagement with China has been limited and at best circumscribed. This owes to factors such as indifference by state authorities to cooperation with civil society actors in negotiating with Chinese actors, the desperation of the The Zimbabwe African National Union – Patriotic Front regime in the face of isolation by erstwhile partners as well as the opacity and secrecy that characterizes significant areas of the Zimbabwe–China relationship. The pressing need for critical institutions such as parliament to play independent oversight roles as well as the creation of space for civil society watchdog functions are highlighted as key enablers if Zimbabwean agency is to generate positive gains from the country’s engagement with China.

- Description: Probiotics for aquaculture are generally only selected by their ability to produce antimicrobial metabolites; however, attachment to intestinal mucus is important in order to remain within the gut of its host. Five candidate probiotics (AP1–AP5), isolated from the clownfish, Amphiprion percula (Lacepéde), were examined for their ability to attach to fish intestinal mucus and compete with two pathogens, Aeromonas hydrophila and Vibrio alginolyticus. Two different radioactive isotopes were used to quantify competition between pathogens and probionts. Attachment of the pathogens was enhanced by the presence of the candidate probiotics. However, the addition of the candidate probiotics after the pathogens resulted in reduced pathogen attachment.

Composition portfolio
- Boesack, Lenrick Jonathan Angus
- Authors: Boesack, Lenrick Jonathan Angus
- Date: 2017
- Subjects: Piano music , Prepared piano music , Saxophone music
- Language: English
- Type: text , Thesis , Masters , MMus
- Identifier: http://hdl.handle.net/10962/56233 , vital:26786
- Description: This short composition portfolio comprises 40% of the requirements for the Master of Music Degree in performance and composition at Rhodes University. In addition to the music presented here, I played two public exam recitals of 70 minutes each. While I played piano as a child, my main instrument during my BMUS studies at the University of Cape Town (2004-2007) was the saxophone. In 2010 I was diagnosed with Polymyositis(an auto-immune desease) which particularly affected my breathing and therefore my ability to play the saxophone. For this reason I opted to play my recitals on the piano. The first recital focused on interpretations of Swing Era, Bebop and post-Bebop standards such as: Someday my prince will come, What is this thing called love, In your own sweet way, Eternal Triangle, Recordame, Peace, Dolphin Dance, Caravan and Some other blues. The second recital comprised of seven original compositions that were presented in trio, quartet and quintet settings.

Computer-aided identification of coelacanths, latimeria chalumnae, using scale patterns

- Description: Despite coelacanths, Latimeria chalumnae, being listed as either endangered by CITES or critically endangered by the IUCN, their population size within South Africa is unknown and still needs to be estimated. Their conservation status unfortunately excludes the use of conventional tagging to mark individual animals for a possible mark-recapture experiment. This study shows that because coelacanths have a unique spot patterning it is possible to quickly and accurately identify specific individuals photographically using computer-aided identification software. Without any manual intervention by an operator, the software accurately identified between 56 and 92% of the individuals. Indentification success increased to 100% if the operator could also manually select from other potential matching photographs. It was also shown that fish exhibiting a yaw angle not exceeding 60˚ could be accurately identified in photographs, although the percentage of fish correctly identified without operator-intervention decreased rapidly with increasing yaw angle. Computer-aided identification should therefore facilitate future coelacanth research as it is both efficient and accurate while also reducing potential stress on the animals observed.
