Infertility is a widespread problem around the world, although the available treatment options constantly improve through research and methodological development. A common treatment option mainly for biologically caused infertility is in-vitro fertilization, where in a menstrual cycle multiple oocytes are stimulated to mature and are then fertilized in a laboratory. This often results in multiple good quality embryos which can be cryopreserved through vitrification and used in a later cycle to increase the success chance of the treatment. The purpose of this pilot study was to evaluate vitrification and warming kits from Kitazato and Irvine Scientific regarding results and procedures. Human cleavage stage embryos (n=76) were thawed and cultured to the blastocyst stage. The blastocysts were scored according to Gardner and cryopreserved with vitrification and warming kits from either Kitazato (n=20) or Irvine Scientific (n=20). The warmed blastocysts were controlled after 2 and 4 hours for re-expansion and freeze injuries. The data was analysed with Fisher’s exact test and considered statistically significant if two-tailed p-value <0.05. The results showed no significant difference between the kits after 2 respectively 4 hours regarding re-expansion (p=0.432; p=0.492) or freeze injury (p=1.000; p=0.476). A significant difference was observed between group AB (with higher Gardner-score) and group C (with lower Gardner-score) in the degree of freeze injury (p=0.048; p=0.034), regardless of vitrification kit used. The details of the procedures differed somewhat between the kits, both having pros and cons, although overall procedures were equivalent. Further evaluation is needed before a change in method can be conducted.

ln mid-1988, Brigham Young University received a high-quality collection of photographic glass plates made by Edith Irvine at the tum of the century. The plates, her camera and other photographic equipment, and miscellaneous publications were donated to BYU by her nephew, Jim Irvine. When the plates arrived and the Archives Photolab had them proofed, we realized thal not only were the San Francisco earthquake/ fire and other areas of California history recorded, but we had, in fact, the work of an outstanding photographer. As we compared the proofs with the work of other photographers who handled similar subjects, we called on faculty members qualified to judge her work. All were unstinting in their praise. As our Archives Curator, Dennis Rowley, looked at them, he said, "I've never seen a sel of photographs create a mood like these do." The more I worked with them, the greater my need to do more than just process and preserve. As I discussed the collection with the faculty members, it became evident to me that I should make a change in my graduate program. I was determined to learn more about the photographer. The collection of photographs can be viewed in the Edith Irvine Collection.

No / The potential of Mg in Arctica islandica as a climate proxy is explored through analysis of live-collected shells from Irvine Bay, NW Scotland. Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) analysis of the right hand valve from two specimens indicates that seasonal Mg/Ca variations do not correlate with seawater temperature. The highest Mg/Ca typically occurs at the annual growth checks in ~ November¿February. Mg/Ca variations between growth checks are significant in one specimen but usually not significant in the other. Mg/Ca measurements taken laterally across the band (i.e. perpendicular to direction of the growth) to determine heterogeneity of the aragonite deposited at the same time indicates that Mg/Ca concentration decreases with increasing distance from the periostracum in both shells. X-ray Absorption Near Edge Spectroscopy (XANES) indicates that Mg is not substituted into aragonite but is hosted by a disordered phase e.g. organic components or nanoparticles of an inorganic phase. Shell Mg/Ca variations may reflect changes in the concentration or composition of the disorded phase, as well as changes in the composition of the extrapallial fluid used for calcification. Such changes could reflect the relative transportation rates of Mg and Ca to the calcification site.

Thesis (MA)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: The stories and histories of the human race are littered with the remnants of utopia. These utopias always exist in some "far away" place, whether this place be removed in terms of time (either as a nostalgically remembered past, or an idealistically projected future), or in terms of space (as a place that one must arrive at). In our attempts to attain these utopias, we construct our worlddefinitions in accordance with our projections of these ideal places and ways of "being". Our discourses come to embody and perpetuate these ideals, which are maintained by excluding any definitions of the world that run counter to these ideals. The continued existence of utopia relies on the subjects of that utopia continuing their belief in its ideals, and not questioning its construction. Counter-discourse to utopia manifests in the same space as the original utopia and gives rise to questions that threaten the stability of the ideal. Questions challenge belief, and therefore the discourse of the ideal must neutralise those who question and challenge it. This process of neutralisation requires that more definitions be constructed within utopian discourse - definitions that allow the subjects of the discourse to objectify the questioner. However, as these new definitions arise, they create yet more counter-definitions, thereby increasing the fragmentation of the aforementioned space. A subject of any "dominant" discourse, removed from that discourse, is exposed to the questions inherent in counter-discourse. In such circumstances, the definitions of the questioner - the "other" - that have previously enabled the subject to disregard the questioner's existence and/or point of view are no longer reinforced, and the subject begins to question those definitions. Once this questioning process starts, the utopia of the subject is re-defined as dystopia, for the questioning highlights the (often violent) methods of exclusion needed to maintain that utopia. Foucault's theory of heterotopia, used as the basis for the analysis of the three texts in question, suggests a space in which several conflicting and contradictory discourses which seemingly bear no relation to each other are found grouped together. Whereas utopia sustains myth in discourse, running with the grain of language, heterotopias run against the grain, undermining the order that we create through language, because they destroy the syntax that holds words and things together. The narrators in the three texts dealt with are all subjects of dominant discourses sustained by exclusive definitions and informed by ideals that require this exclusion in order to exist. Displaced into spaces that subvert the definitions within their discourses, the narrators experience a sense of "madness", resulting from the disintegration of their perception of "order". However, through embracing and perpetuating that which challenged their established sense of identity, the narrators can regain their sense of agency, and so their narratives become vehicles for the reconstitution of the subject-status of the narrators, as well as a means of perpetuating the counter-discourse. / AFRIKAANSE OPSOMMING: Utopias spikkel die landskap van menseheugenis as plekke in "lank lank gelede" of "eendag", in "n land baie ver van hier", en is dus altyd verwyderd van die huidige, óf in ruimte, óf in tyd. In ons strewe na die ideale, skep ons definisies van die wêreld wat in voeling is met hierdie idealistiese plekke en bestaanswyses. Sulke definisies sypel deur die diskoers, of taal, waarmee ons ons omgewing beskryf. Die ideale wat dan in die diskoers omvat word, word onderhou deur die uitsluiting van enige definisie wat teenstrydig is met dié in die idealistiese diskoers. Die volgehoue bestaan van utopie berus daarop dat die subjekte van daardie utopie voortdurend glo in die ideale voorgehou in en onderhou deur die diskoers, en dus nie die diskoers se konstruksie bevraagteken nie. Die manifestering van teen-diskoers in dieselfde ruimte as die utopie, gee aanleiding tot vrae wat die bestaan van die ideaal bedreig omdat geloof in die ideaal noodsaaklik is vir die ideaal se voortbestaan. Aangesien bevraagtekening dikwels geloof uitdaag en ontwrig, lei dit daartoe dat die diskoers wat die ideaal onderhou, diegene wat dit bevraagteken, neutraliseer. Hierdie neutraliseringsproses behels die vorming van nog definisies binne die diskoers wat die vraagsteller objektiveer. Die vorming van nuwe definisies loop op sy beurt uit op die vorming van teen-definisies wat bloot verdere verbrokkeling van die voorgenoemde ruimte veroorsaak. "n Subjek van die "dominante" diskoers van die utopie wat hom- /haarself buite die spergebiede van sy/haar diskoers bevind, word blootgestel aan vrae wat in teen-diskoers omvat word. In sulke omstandighede is die subjek verwyder van die versterking van daardie definisies wat die vraagsteller - die "ander" - se opinies of bestaan as nietig voorgestel het, en die subjek mag dan hierdie definisies bevraagteken. Sodra hierdie proses begin, vind "n herdefinisie van ruimte plaas, en utopie word distopie soos die vrae (soms geweldadige) uitsluitingsmetodes wat die onderhoud van die ideaal behels, aan die lig bring en, in sommige gevalle, aan die kaak stel. Hierdie tesis gebruik Foucault se teorie van "heterotopia" om die drie tekste te analiseer. Dié teorie veronderstel "n ruimte waarin die oorvleueling van verskeie teenstrydighede (diskoerse) plaasvind. Waar utopie die bestaan van fabels en diskoerse akkommodeer, ondermyn heterotopia die orde wat ons deur taal en definisie skep omdat dit die sintaks vernietig wat woorde aan konsepte koppel. Die drie vertellers is elkeen "n subjek van "n "dominante diskoers" wat onderhou word deur uitsluitende definisies in "n utopia waar die voortgesette bestaan van die ideale wat in die diskoers omvat word op eksklusiwiteit staatmaak. Omdat die vertellers verplaas is na ruimtes wat hulle eksklusiewe definisies omverwerp, vind hulle dat hulle aan "n soort waansin grens wat veroorsaak is deur die verbrokkeling van hul sin van "orde". Deur die teen-diskoers in hul stories in te bou as verteltaal, of te implementeer as die meganisme van oordrag, kan die vertellers hul "selfsin" herwin. Deur vertelling hervestig die vertellers dus hul status as subjek, en verseker hulle hul plek in die opkomende diskoers deur middel van hulle voortsetting daarvan.

While Skagboys portrays the descent into heroin addiction of young, working class Scots during the Thatcher era, shifting the analysis from a strictly human perspective to one focusing on the agency of objects opens up the novel to new readings wherein morality emerges through nonhuman actors. Welsh’s work has traditionally been hailed as Scottish working-class realism that portrays its characters unideologically, to the point that the novels, through the characters, appear without morality. Drawing upon Latour’s notion of Actor-Network Theory, ANT, reveals a Thatcherite materiality permeating the story, prescribing the moral behaviour which the characters of Skagboys repeatedly clash with as their heroin addiction and junk desperation grows. The impacts of the security camera, the smoke detector and the collection tin provide the basis for the analysis. This highlights two types of marginalization for the characters. Firstly, in the characters’ hopeless prospects with regards to employment due to Thatcher’s neoliberal politics, and secondly as objects of detection and control exerting agency in the world which the characters navigate. These objects presuppose and foil crime, effectively becoming extensions of Thatcherite morality, keeping the criminal and unemployed in check.

Mémoire numérisé par la Direction des bibliothèques de l'Université de Montréal. / Les observations des neutrinos atmosphériques dans les détecteurs Kamiokande (Japon) et Irvine-Michigan-Brookhaven (1MB, Etats-Unis) font preuve d'une anomalie dans le rapport v^/Ve- Le phénomène d'osciUations de neutrinos v^-^Vx est une explication possible de cette anomalie. Le projet d'expérience E889 à l'AGS de Brookhaven avait pour objet la recherche des oscillations de neutrinos à longue distance en utilisant un faisceau de neutrinos muoniques ayant une énergie moyenne Ey ^ l GeV. <J La masse des neutrinos et le mélange entre les saveurs sont les deux caractéristiques qui définissent les oscillations entre saveurs de neutrinos. L'observation des oscillations aurait d'importantes conséquences en physique des particules, en astrophysique et en cosmologie. Dans la proposition de l'expérience E889, quatre énormes détecteurs Cerenkov à eau sont utilisés pour observer le faisceau de neutrinos, jusqu'à une distance de 68 km. Pour comprendre le signal Cerenkov produit par des particules chargées dans ces détecteurs, une étude par simulation Monte-Carlo de l'éinission Cerenkov par des inuons, électrons et des rayons gamina est présentée. Cette étude identifie quelques différences significatives entre la distribution de l'éimssion Cerenkov de ces particules. On peut envisager la possibilité de discriminer entre les gerbes électromagnétiques induites par un électron ou par un rayon gamma: la predominance de la production de paires (7-«-e+e-) par les rayons gamma de haute énergie (E^ ^ 25 MeV) conduit à une intensité de lumière Cerenkov plus élevée pendant les premières longueurs de radiation. Deux geometries pour les détecteurs sont étudiées: la première ayant 3562 phototubes de 8 pouces de diamètre par détecteur, et la deiixièine ayant 946 phototubes de 20 pouces de diamètre (configuration similaire au détecteur Kamiokande). Quant à la reconstruction des particules (vertex de l'interaction, impulsions des particules secondaires et identification des particules), les deux géoinétries ont une perforinance similaire. IV Les interactions à courant neutre (CN) peuvent servir à la norinalisation du flux total de neutrinos. La production de pions neutres par une interaction neutrino-nucléon à courant neutre fournit un signal clair dans un détecteur ôerenkov à eau, grâce aux deiix anneaux provenant des gerbes électromagnétiques dans la désintégration 7r°-^77. Une analyse d'événements CN(7r°) est présentée qui tient compte de plusieurs sources de contamination venant d autres types d'interactions produisant égaleinent deux anneaux. Cette analyse démontre que ce mode est clairement identifiable, et peut être utilisé pour la normalisation du taux d événements quasi-élastiques v^n-^p,~p, ou comme signal de disparition dans le cas des oscillations vers un état stérile v^-^v,. Dans le cas des osciUations v^,-^Ve,ri la sensibilité est assez bonne pour couvrir entièrement la portion du plan (Am2,sin 28) qui correspond à l'anomalie atmosphérique. La sensibilité est moins bonne pour les oscillations v^^-v,, et une prise de données plus longué que prévue serait nécessaire pour augmenter le nombre d'événements CN(7T°) observes.

This research provides an analytical reading of four contemporary novels, in a transcultural study of magical realism and dreams. Two of the novels, Ben Okri's The Famished Road and its sequel Songs of Enchantment, examine dreams through magical realism in postcolonial African literature. The third novel, Toni Morrison's Beloved, is used to depict the use of memory within an African-American magical realist novel. And the fourth narrative is Irvine Welsh's Marabou Stork Nightmares, which focuses on the use of hallucination within what can be seen as a magical realist mode. The analysis of these novels examines certain aspects of magical realism, including the use of the subconscious, focusing primarily on dream, memory and hallucination. In examining this topic, I aim to suggest that the use of the subconscious, within this literature, allows the writer to comment on a particular society. As can be seen in previous studies of magical realism, the writer is able to express his or her dissatisfaction with society by destabilising conventionally accepted truths. A writer can therefore convey a sense that the surface of a particular culture or society is a facade, disguising certain hidden truths, which require a more in depth examination, in order to more fully understand the workings behind that society. The subconscious works to reveal these hidden realities, and is therefore a mode of resistance in that it allows the writers an avenue through which to express their dissatisfaction with their particular society. This is achieved through the exploring and deconstruction of certain boundaries within the novels which, along with several other factors, essentially concords the magical realism inherent in these texts. It is additionally enhanced through the use of the device of the subconscious, which allows the writers to transgress borders, and further explore their particular cultures. Through the use of novels from various contemporary societies, I hope to establish the fact that the subconscious, and therefore magical realism, is a transcultural technique, in that it traverses a multitude of cultures, without being specific to any one in particular. While the use of dreams requires a culture specific interpretation, the use of the subconscious in this literature can be seen as a global technique of expressing dissatisfaction within these societies. / Thesis (M.A.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.
