Sa realisation a ete rendue possible grace a la collaboration de Γ fiphorie qui a facilite les travaux pratiques dans le musee.
Le lemme epigraphique est du aux etudiants qui sont aussi responsables de P etablissement des textes: lectures nouvelles, obvservations permettant de rejetter des restitutions deja proposees ou confirmant des restitutions jusqu’alors incertaines. Tout cela a regu mon aval. Certai- nes lectures ou remarques plus complexes sont le resultat de ma collaboration avec les etudiants lorsque nous avons revu les pierres. Je suis, quant a moi, responsable de la description des pierres et, pour de raisons d* homogeneity, de la redaction du recueil. L΄ etablissement du lemme epigraphique s* est particuli£rement heurte au probleme du retard de la parution de certaines revues grecques comme Γ Arch. Delt., Chron., retard qui fait qu’une inscription apparait souvent plus tot dans les Chroniques de revues comme le BCH ou le JHS que dans son editio princeps. Pour des raisons analogues, il n* a pas ete toujours possible d' indiquer, entre parentheses, a la suite d* une inscription le lemme du Bull. ep. ou du SEG qui s’y rapporte.

PGHSs catalyze the oxygenation of fatty acyl substrates (FAH) such as arachidonic acid (AA). This is the committed step in the generation of prostaglandin H2 (PGH2). PGH2 is the substrate for five downstream isomerases that lead to the generation of prostaglandins. Prostaglandins mediate a variety of physiological effects, such as pain, inflammation, fever, vascular homeostasis, and parturition, by their actions at several prostaglandin-specific G-protein coupled receptors (GPCRs). The endogenous ligands for the cannabinoid receptors, arachidonoyl ethanolamine (AEA) and 2-arachidonoyl glycerol (2-AG) are substrates for the second isoform of PGHS, PGHS-2. Their oxygenation leads to the generation of AEA and 2-AG derived prostaglandins (PG-EAs and PG-Gs). PG-Gs have been shown to have unique actions at yet to be identified GPCRs including, mobilizing Ca2+ at the picomolar level in cell culture, and causing a concentration dependent hyperalgesia (exaggerated pain) and allodynia (pain in response to non-pain evoking stimuli). To determine the biochemical determinants of the oxygenation of 2-AG by PGHS-2, I compared the abilities of AA derived hydroperoxides to 2-AG derived peroxides as substrates and activators of the oxygenase function of PGHS. I demonstrated that PGG2 and PGG2-G were both equivalent substrates for PGHS-2. Interestingly, the oxygenation of 2-AG demonstrated and increased need for the concentrations of peroxide required to activate its oxygenation. In the presence of increased peroxide scavenging by glutathione peroxide (GPx), the oxygenation of 2-AG was almost abrogated compared to relatively unaffected AA oxygenation. Specifically, I demonstrated that the depletion of the membrane associated GPx (GPx4), leads to increased oxidant stress and peroxide tone, and significantly increased oxygenation of 2-AG in murine derived cells.
These results led us to conclude that the oxygenation of 2-AG is exquisitely sensitive to the concentration of oxygenase activating peroxide. Chemical ligands specifically designed to target the peroxidase active site of PGHS have to date not been reported. I designed a chemical mimic of PGHS-2 substrate PGG2 and developed a chemical ligand that inhibited the turnover of peroxide at the peroxidase active site of PGHS. This lead compound forms a new class of molecule that can specifically and potently inhibit the oxygenation of 2-AG by PGHS-2, while having no impact on AA oxygenation. It could form a useful tool for the dissection of the physiological role of PGHS-2 mediated 2-AG oxygenation
Market dynamics as a driver towards the evolution of research needs : the case of up-flow anaerobic sludge blanket seeding granules

certain aspects of, a particular technology. Our case study results illustrate how market dynamics have influenced the evolution of research needs in the wastewater treatment sector, with specific emphasis on research on the seeding granules used to
start up-flow anaerobic sludge blanket (UASB) reactors. Because of insufficient data on the actual market demand for seeding
granules for UASB plants, surrogate data, on the number of UASB plants installed internationally from 1970 to 2007, were
used to predict the potential future demand for seeding granules. Secondly, we also determined whether or not such a demand
would provide sufficient economic justification for the installation of one or more plants for manufacturing seeding granules
in South Africa. The direct relationship between the demand for seeding granules and increased numbers of UASB plants
was based on the premise that the start-up of each plant required a seeding inoculum before effluent could be treated. Three
methods were used to obtain the data used in this study, namely: a literature survey, a questionnaire survey, and interviews
with people having expert knowledge of wastewater treatment technologies. Our findings suggest that the UASB technology
has largely been marginalised in the wastewater treatment market because of the introduction of competing technologies,
and due to high initial capital costs. As a result, South African market demand for the seeding granules is likely to be very
small or non-existent, because the number of new UASB plants installed per year is likely to decrease in future. Secondly, our
research suggests that market dynamics, political contexts and technologies will continue to change, exerting an increasing
downward influence on the UASB technology over time.Publisher's versio
Post-treatment of distillery wastewater after UASB using aerobic techniques

South African Journal of Enology & Viticulture, 28(1):50-55, doi:10.21548/28-1-1459The original publication is available at http://www.journals.ac.za/index.php/sajevThe treatment of high-strength wastewater from a distillery using grape-based feedstock was conducted through sequencing the upflow anaerobic sludge blanket (UASB) reactor and the aerobically-activated sludge reactors. The performance of the UASB system was evaluated at the end of a period of 33 days in terms of the final chemical oxygen demand (COD) removal. Final COD removal efficiency of up to 88.7% was achieved. The effect of varying the volumetric loading rates on COD removal was evaluated for the two experimental runs. For run I (undiluted), the volumetric loading rates ranged from 4.06 to 18.90 kg COD/m3.day and the maximum COD removal achieved by the reactor was 57.1%. For experimental run II (diluted), the loading rates ranged between 3.60 to 8.20 kg COD/m3.day, with the reactor achieving 88.7% COD removal. Post-treatment of the effluent using the aerobicallyactivated sludge reactor further improved the overall COD removal in run II to 96.5% and also reduced the phosphorous in the effluent to a final value of approximately 20 mg/L. These experimental results indicate that sequential treatment of the distillery wastewater using UASB followed by aerobically-activated sludge treatment is an efficient system that makes the final effluent compliant with the requirements of environmental legislation.http://www.journals.ac.za/index.php/sajev/article/view/1459Publisher's versio

An integrated approach to waste and energy minimization in the wine industry : a knowledge-based decision methodology
No full textThesis (PhD)--University of Stellenbosch, 2004.ENGLISH ABSTRACT: The importance of waste management is growing rapidly for several reasons. These
reasons include the escalating cost of wastewater treatment and cleaning chemicals, an
emerging trend of onerous regulatory regime regarding e uent disposal from governments,
rising public awareness on the adverse e ects of industrial waste as well as drastic reduc-
tion in water resources in the winegrowing regions. In addition, owing to the large energy
demand for refrigeration purposes for high quality wine production and rapidly increasing
energy costs, the challenges of energy management in the wine industry were also inves-
tigated.
In order to address these challenges adequately, the solutions were derived via the
integration of two disciplines: environmental science (waste and energy management)
and computer science (applications of arti cial intelligence). Therefore, the ndings re-
ported from this study seek to advance knowledge through the construction of decision
support systems for waste and energy management in circumstances where conventional
mathematical formalisms are inadequate. In that sense, the dissertation constitutes in-
terdisciplinary research on the application of integrated arti cial intelligence technologies
(expert systems and fuzzy logic) in designing and developing decision tools for waste and
energy management in the wine industry.
The dissertation rst presents the domain of interest, where the scope and breadth of
the problems it addresses are clearly de ned. Critical examination of the domain data-
bases revealed that data, information, and knowledge for waste and energy management
in the wine industry are generally incomplete and lack structure overall. Owing to these
characteristics, a hybrid system approach was proposed for the development of decision
support systems based on fuzzy logic. The integrated decision support systems were de-
veloped based on an object-oriented architecture. This approach facilitated the
exible
design required for waste and energy management-related complex problem-solving.
To illustrate the applicability of the o -line decision tools developed, several case stud-
ies mirroring on actual industrial practices were considered. These systems were found to
be robust and yielded results that were in accordance with actual industrial practices inthe wine industry. Furthermore, they provided intelligent suggestions in scenarios where
there was minimal information, and under certain instances they o ered feasible sugges-
tions in circumstances where a human novice could have problems in making the right
decisions.AFRIKAANSE OPSOMMING: Die belangrikheid van afvalbestuur neem om verskeie redes vinnig toe. Die redes sluit
in die eskalerende koste van afvalwaterbehandeling en skoonmaakmiddels, streng regula-
toriese vereistes van regeringskant met betrekking tot die verwydering van uitvloeisels,
toenemende openbare bewustheid van die nadelinge e ekte van nywerheidsafval, sowel
as die drastiese afname in waterbronne in wynproduserende omgewings. Daarby, a.g.v.
die groot energieverbruik wat deur die verkoeling van hokwaliteitwyn vereis word en die
snelgroeiende energiekoste, is die uitdagings van energiebestuur in die wynbedryf ook on-
dersoek.
Ten einde die uitdagings die hoof te kon bied, is oplossings gevind deur die integrasie
van twee disciplines: omgewingswetenskap (afval- en energiebestuur) en rekenaarweten-
skap (toepassings van kunsmatige intelligensie). Gevolglik is daar deur die bevindinge
van die studie gepoog om kennis te bevorder deur die konstruksie van besluitnemingson-
dersteuningstelsels vir afval- en energiebestuur onder omstandighede waar konvensionele
wiskundige algoritmes ontoereikend sou wees. In die opsig verteenwoordig die proefskrif
interdissiplinre navorsing in die toepassing van gentegreerde kunsmatige intelligensieteg-
nologie (kundige stelsels en wasige logika) in die ontwerp en ontwikkeling van besluitne-
mingshulpmiddels vir afval- en energiebestuur in die wynindustrie.
Die proefskrif baken eers die probleemgebied af, waarna die bestek en omvang van die
probleme waarop die werk gemik is duidelik gede nieer word. Kritiese ondersoek van
die databasisse in die domein het getoon dat die data, informasie en kennis oor afval- en
energiebestuur in die wynbedryf in die algemeen onvolledig en gebrekkig gestruktureer is.
A.g.v. di eienskappe, is 'n hibriede stelselbeandering voorgestel vir die ontwikkeling van
besluitnemingstelsels gegrond op wasige logika. Die gentegreerde besluitnemingsonders-
teuningstelsels is ontwikkel op 'n objek-georinteerde argitektuur. Die benadering het die
daarstelling van 'n buigsame ontwerp wat benodig word vir komplekse probleemoplossing
in afval- en energiebestuur vergemaklik.
Om die toepaslikheid van die a
ynige besluitnemingshulpmiddels wat ontwerp is, te
illustreer, is verskeie gevallestudies wat werklike industrile praktyk uitbeeld beskou. Diestelsels was robuust en het resultate gelewer wat in ooreenstemming was met werklike
industrile praktyke in die wynnywerheid. Die kundige stelsels het verder intelligente
voorstelle gemaak in scenarios waar daar minimale informasie beskikbaar was, en onder
sekere omstandighede het hulle realistiese oplossings voorgestel waar 'n onkundige persoon
probleme sou gehad he tom die regte besluite te kon neem.Doctora
