Introduktion och syfte: Kariesutveckling influeras av faktorer hos både värd och bakterier. Men när olika individer exponeras för samma nivåer av externa riskfaktorer, är en del individer mer mottagliga för karies jämfört med andra. En förklaring skulle kunna vara olika glykosylering av glykoprotein i saliven. I denna pilotstudie undersökte vi skillnaden i nivåer av monosackariderna sialinsyra, fukos och galaktos hos personer som aldrig haft karies och personer som har/har haft karies. Syftet var även att undersöka om plackenzym kan vara en modifierare av nämnda glykoprotein.Material och metod: Två grupper, med 10 individer i varje, inkluderades i studien. Ena gruppen hade DMFT = 0 och den andra DMFT ≥ 1. Saliv och plack samlades och innehållet av bundna monosackarider (sialinsyra, fukos och galaktos) samt glykosidaser (sialidas, β-fukosidas, β-galaktosidas, α-glukosidas och N-acetylglukosaminidas) analyserades med en fluorometer. Även salivflödet kalkylerades.Resultat: Innehållet av både sialinsyra och galaktos var signifikant högre i gruppen med DMFT = 0, medan innehållet av fukos inte skilde sig åt signifikant mellan grupperna. Ingen signifikant skillnad kunde ses mellan de två grupperna avseende enzymaktivitet och salivflöde.Konklusion: Högre nivåer av bunden sialinsyra och galaktos fanns hos gruppen med DMFT = 0. Resultaten indikerar att dessa monosackarider kan vara en möjlig markör för oral hälsa. Större longitudinella studier behövs för att verifiera sambandet. / Introduction and aim: Caries development is affected by factors within bacteria and host. But when different individuals are exposed to same levels of external risk factors, some individuals are still more susceptible to caries. One explanation could be different glycosylation of salivary glycoproteins. In this pilot study, we investigated the difference in levels of the monosaccharides sialic acid, fucose and galactose between individuals with or without previous caries experience. We also aimed to investigate if plaque glycosidases could be a modifier of these glycoproteins.Material and method: Two groups, with 10 subject in each, were included in this study. One group had DMFT = 0 and the other DMFT ≥ 1. Saliva and plaque were collected and content of bound monosaccharides (sialic acid, fucose and galactose) and glycosidases (sialidase, α-fucosidase, β-galactosidase, α-glucosidase and N-acetylglucosaminidase) were detected using absorbance and fluoroscens respectively. Salivary flow rate was also measured.Results: Content of both sialic acid and galactose were significantly higher in the group with DMFT = 0, while the content of fucose did not differ significantly between the groups. No significant differences could be seen between the two groups (DMFT = 0 and DMFT ≥ 1) regarding any of the investigated glycosidases and salivary flow rate. Conclusion: Higher levels of bound sialic acid and galactose were found in the group with DMFT = 0 and the results indicate that these monosaccharides could be a possible marker for oral health. Larger longitudinal studies are needed to verify this correlation.

Text in Afrikaans / Hierdie studie is 'n herskepping van die wereld van die Afrikaanse roman van 1934-1939. Al die romans is bekom en gelees. Die beskikbaarheid van hierdie romans word aangedui. 'n Sketsmatige beeld van elke roman word gegee, waarin die aard daarvan aangetoon word ten opsigte van die volgende aspekte: milieu, tema en konflik (moreel, religieus, maatskaplik, polities). Die lotgevalle van hierdie romans is nagegaan aan die hand van tydgenootlike resepsiegeskiedenis, sowel as die van die literatuurgeskiedskrywing tot op hede. Hieruit het dit geblyk dat sekere romans aanvanklik hoog aangeslaan is, maar nie in die kanon opgeneem is nie. Moontlike redes hiervoor word ondersoek. Na my oordeel verdien Die loutering van Petrus deur Ella Fischer en Die jare daarna deur Aletta Steyn 'n herbesoek. Albei romans is boeiend en interessant, die karakters "lewe" en dit wat hul beleef en ervaar, spreek steeds tot die leser van die negentigerjare / This study is a recreation of the world of the Afrikaans novel of 1934-1939. All the novels were obtained and read. The availability of these novels is indicated. A schematic account of each novel is given, in which the nature of each is explicated in respect of the following aspects: milieu, theme and conflict (moral, religious, social and political). The fate of these novels was researched in the context of their contemporary reception history and that of literary historiography to date. From the study it appears that certain novels were initially highly acclaimed, but were not included in the canon. Possible reasons for this are investigated. It is my opinion that Die loutering van Petrus by Ella Fischer and Die }are daarna by Aletta Steyn need to be re-evaluated. Both novels are absorbing and interesting, the characters are lifelike and their life experiences are still relevant to the reader of the nineties / Afrikaans & Theory of Literature / M.A. (Afrikaans)

This thesis explores solo performance in New Zealand. That solo performance has been widely used in New Zealand's relatively brief theatre history is usually ascribed to the economy, manoeuvrability and adaptability of the form - common reasons for the popularity of solo performance elsewhere as well. But this thesis considers solo performance as a kind of theatre that has been suited to New Zealand in a distinctive way. In particular, I argue that solo performance has emerged on the margins of mainstream theatre in New Zealand as a means of actively engaging with a sense of isolation that typifies the post-colonial New Zealand experience. The ability of the solo performance to move between remote rural settlements and urban centres has connected these New Zealand communities in a way that is unusual for theatre in New Zealand. Furthermore, a solo performer speaking directly to an audience about the experience of living in New Zealand allows for an intimate interaction with a traditionally stoic and laconic masculine society. In this thesis, I make a case for three solo performances where it is possible to see, in the representation of a search for what it means to be a New Zealander, a theatrical contribution to nation-building: The End of the Golden Weather (1959), Coaltown Blues (1984) and Michael James Manaia (1991). However, in a subsequent chapter, I look at solo performances in New Zealand that might better be understood within global movements such as feminism and multiculturalism. I argue that this shift has depleted the power that the form once held to comment upon New Zealand identity and to assist in the search for national identity. I conclude the thesis by considering how ongoing theatre practice may be informed by the experience of solo performance in New Zealand.
