La chasse occupe une place significative dans les textes des auteurs américains Jim Harrison et Thomas McGuane. Elle apparaît soit comme un thème central, traité directement et pour lui-même, soit comme un thème secondaire ou encore comme une métaphore ou un motif sous-jacent qui permet de mieux comprendre les enjeux du texte, ses implications morales et esthétiques. Dans le corpus, la chasse correspond à une stratégie d'écriture fondée sur le leurre, lorsqu'elle recouvre ou qu'elle révèle un sens second. Le motif du double a partie liée dans le corpus avec la complexité du chasseur, un personnage qui dramatise des visées contradictoires : il est partagé entre le respect de la proie et le désir de la posséder. Le sportsman se confronte aux limites de son champ d'action qu'il détermine pour les respecter, alors que par contraste, certaines figures sont présentées comme des contre-modèles qui transgressent les bornes. Cependant, la transgression apporte dans certains cas un bénéfice au personnage et au groupe auquel il se réfère. Le chasseur revêt alors une fonction paradoxale : il incarne celui qui révèle que les bornes doivent être déplacées et dont la chasse "noire" redéfinit les limites de fait. Il fait figure de modèle paradoxal, dans le récit mais aussi d 'un point de vue métatextuel Chez Harrison et McGuane, les textes sur la chasse invitent à considérer l'écrivain comme un "chasseur noir" qui braconne sur les terres d'autres auteurs et d'autres systèmes de représentation mais dont la transgression est finalement valorisée : le souci de justesse qu'il incarne nécessite un travail d'accommodement à un monde changeant et donc le renouvellement des bornes et des formes. L'idéal sportif de la relâche du gibier reflète l'entreprise de l'écrivain : le souci de la distance à garder face à l'animal et celui de redéfinir les cadres formels se manifestent à travers une esthétique de la déprise qui remet le sens du texte en mouvement. / In the writings of the American authors Jim Harrison and Thomas McGuane, hunting is a central theme. Even when it is not the main topic of the text, hunting is significant. It may be one of the main themes, tackled directly for itself or it can be an ancillary tl1eme used as a metaphor or as an implicit motif in the structure. Hunting is also a writing strategy, reproducing the mimetic seduction of the lure, hiding or revealing a second meaning. The motif of the double is indeed central; it has to do with the logics of make-believe but also with the complex character of the hunter who enacts contradictory tendencies: torn between his respect for the prey and his desire to grasp and kill it, he also embodies an ambivalent attitude toward the Law. The sportsman faces the limits of his scope; he defines them so as to respect tl1em. By contrast other character-types are presented as foils to the sportsman. Their transgression may however become beneficient to the group he belongs to. In such cases, ehe hunter has a paradoxical function: he reveals that the landmarks must be displaced and his "black hunt" effectively replaces them. He embodies a paradoxical model in the story and for tl1e writer. Harrison's and McGuane's texts thus suggest to look at the writer as "black hunter" who trespasses into other writers' territories, also violating the limits conventionally separating several systems of representation. This transgression proves fruitful and as such is valorized. The hunter and the writer try to adjust and accommodate to a changing world; this quest implies new frames. The sportsman's ideal of catch-and-release reflects tl1e writer's aesthetics of release: both try to put the game back in movement.

The manufacture of nonionic surfactants generally involves ethoxylation via ethylene oxide condensation onto a hydrophobe substrate, mostly in the presence of an alkaline catalyst. Nonionic surfactants are used widely in industrial applications, such as detergents, health and personal care, coatings, and polymers. In Australia, approximately one-third of the annual consumption of nonionic surfactants is imported from offshore manufacturers; the market is highly competitive with the local manufacturer facing increasing competition from imports. Optimisation is a pressing need for the current manufacturing plant of the industrial partner for this research project, Huntsman Corporation Australia Pty Limited, the sole domestic manufacturer of nonionic surfactants in Australia. Therefore, the objectives of this research project were to gain a better understanding of the various chemical and physical processes occurring simultaneously in an ethoxylation process; to identify the process limitation in an existing production plant operated by Huntsman Corporation Australia, and to explore measures for enhancing the asset productivity of the production plant. An ethoxylation process working model, describing the chemical kinetics and the physical transport processes involved, was developed to aid the exploration of optimisation opportunities, which would otherwise be empirical. Accordingly, this research project was structured into a two-stage program. The first stage determined the ethoxylation kinetics experimentally. The second stage investigated the interactions of physical transport processes numerically using a computational fluid dynamics (CFD) technique. The manufacturing scheme discussed in this thesis gave particular emphasis to the ethoxylation process operated in semi-batch stirred reactors. In the first stage, a series of kinetic experiments was performed in a well-stirred laboratory autoclave under base-catalysed conditions. The experimental outcomes were developed into a comprehensive kinetic model which took into account the non-ideal features in the reactor operation. Time-dependent physical changes of the reaction system, such as liquid volume, ethylene oxide solubility and density were also included. The ethoxylation behaviour predicted by the model was shown to be in good agreement with the experimental measurements. This indicated that the kinetic model was sufficiently robust to reproduce the reaction behaviour of a commercially operated ethoxylation operation. In the second stage, numerical simulations of an existing ethoxylation reactor system were presented. In addition, two components were addressed: identification of the process limitation and increasing productivity of the industrial-scale ethoxylation plant. An important assumption was made for the ethylene oxide injection system used in this research project which subsequently simplified the ethoxylation system into a single liquid with miscible chemical species. In the identification of the process limitation, three possible rate-limiting factors were examined: mixing, heat removal and reactor pressure rating. Examination and analysis of the physical data available from plant batch reports found that the reactor pressure rating and the presence of nitrogen padding were the rate-limiting factors to the ethoxylation operations in the industrial reactors. It was recommended that the reactor pressure rating be increased to raise the asset productivity of the reactor. In the numerical simulations of the ethoxylation reactor, time-dependent CFD models were developed for two systems: the ethylene oxide injection pipe and the stirred ethoxylation reactors. The heat transfer of ethylene oxide liquid injection was calculated in a two-dimensional model of the dip-leg pipe used in an industrial-scale ethoxylation reactor. The computation gave the temperature of the injection outflow which was validated against the calculated value by empirical correlation. The effects of various surrounding reaction temperatures, injection rates and pipe sizes on the heat transfer rate were investigated. From these, a range of operating conditions yielding a liquid ethylene oxide outflow was selected. Furthermore, it was found that boiling of ethylene oxide was significantly reduced with increasing pipe diameters. It was recommended that the asset productivity of the reactor be improved by keeping more ethylene oxide injected as a liquid in the reaction mixture to raise the reaction rate and shorten the reaction time. Three-dimensional simulations of a baffled reactor agitated by a single- or a dual-Rushton impeller were presented for both non-reactive and reactive flows. Multiple frames of reference and sliding grid methods were used in sequence to describe the relative motion between the rotating impeller and the stationary baffles. The turbulence parameters were modelled with the standard k- � turbulence model. The simulations of non-reactive flow were compared with the literature velocity data obtained from both the experiments and simulations. Good agreement was achieved. The model was then extended to incorporate ethoxylation flow with integration of the kinetics established in the first stage. Both the laboratory autoclave and the industrial-scale reactors were simulated. The former took into account the ethoxylation exotherm and the latter was carried out isothermally. Both simulations were validated against reaction data obtained from physical experiments, either the kinetic experiments or the plant batch productions. The validated model allowed us to determine the optimum operating condition and explore a new reactor system with enhanced asset productivity. A 50% increase in productivity could be accomplished if the ethoxylation was operated closer to the current design pressure limit. Furthermore, the operating pressure of a new reactor system needed to be doubled if the asset productivity were to be increased to approximately three times the current performance.

The purpose of this study was to examine the relationship between media use and body image in senior citizens. This study specifically targeted older people who participate in regular physical activity. Seniors participating in the 2006 Huntsman World Senior Games in St. George, Utah were surveyed concerning current body image and total media use. The sample included 691 participants. Lower body image scores were recorded among seniors who watched greater amounts of television. Magazine readership and body image displayed no relationship among men or women. Total media use did not influence body image scores among seniors. Male participants exhibited a stronger relationship than female participants between television use and low body image scores. Results indicated that males were vulnerable to messages targeting body image in a similar way to that of females. The findings of this study suggest that individuals may still be influenced by ultra thin images prevalent in media well into their older years.

This document focuses on the formal structures and tonal language of four trios that include horn by American composer Simon A. Sargon: "Huntsman, What Quarry?" Two Poems of Edna St. Vincent Millay for Soprano, Horn, and Piano (1990); Trio for Horn, Violin, and Piano: "The Legacy" (1993); A Clear Midnight: Six Songs Set to Poems of Walt Whitman for Baritone, Horn, and Piano (1996); and Sonic Portals: Trio for Oboe, Horn, and Piano (2003). Comparisons with precedent works of like instrumentation demonstrate that Sargon's trios, though musically unique, merit a place alongside masterworks like Carl Reinecke's Trio, op. 188, for oboe, horn, and piano; Franz Schubert's Auf dem Strom for soprano, horn, and piano; and especially Johannes Brahms's Trio, op. 40, for violin, horn, and piano. Other precedent, contemporary, and related works are also mentioned. Sargon's ability to write idiomatically for the horn and other instruments is discussed, and consideration is given to some elements required to create a good performance of Sargon's chamber music. Included are a brief biography of Simon Sargon, letters from colleagues with whom he has worked closely, lists of his instrumental music and recordings of some of these pieces, and lists of other works in the genres discussed herein.

This thesis analyses 21st century filmic, televisual and comic “Snow White” adaptations. The research is interdisciplinary, bringing together scholarship on gender, childhood, ageing, adaptation, media and fairy tales. The first half of the thesis contextualises the broader historical and sociocultural conversation “Snow White” tellings are immersed in by nature of their shared culture and history. It also identifies the tale’s core and traces the tale’s formation as a tale type from the seventeenth to the twenty–first century. The second half of this thesis moves to an analysis of two films (Mirror Mirror, 2012; Snow White and the Huntsman, 2012), a television series (Once Upon a Time, 2011–present) and a comic book series (Fables, 2002–2015). It considers the kinds of stories about female growth and ageing different media adaptations of “Snow White” enable, and contemplates how issues of time and temporality and growth and ageing play out in these four versions. In analysing the relationship between form and content, this thesis illustrates how a study of different media adaptations of “Snow White” can enrich fairy–tale scholarship and the fairy–tale canon. It also details the imaginative space different media adaptations of “Snow White” provide when engaging with dominant discourses around female growth and ageing in the West. Using “Snow White” as a case study, this thesis centrally facilitates a dialogue between ageing, childhood, fairy–tale and adaptation studies.

With the invention of the printing press, fairy tales became limited by the idea of an "original" (Pettitt, 2009; Blamires, 2003). However, in the past century, the retelling and changing of fairy tales has become incredibly popular in all forms of media, such as print, film, ballet, musicals, etc. Despite Western populations' familiarity with these tales, the demand for such retellings continues to rise, with the storytellers finding great financial success with each "new" version they provide. Researchers have many varying opinions on the reasons for such intense responses to retold fairy tales, but there is a gap of research on the actual changes made to the retold tales and what they mean. Through the use of Narrative Criticism, three of the most popularly retold fairy tales (Cinderella, Beauty and the Beast, and Snow White) were analyzed for the biggest alterations, and what those alterations are meant to convey to consumers. Findings revealed that the biggest changes across all three retellings were those of character, narrator, audience, and setting. These changes indicate a switch from the authoritative nature of the first printed versions to an inferential nature with the subsequent retellings, with authors leaning into the Narrative Paradigm and forcing audiences to instead ruminate on the changes made in the familiar tales, and to decide for themselves what those changes mean for their personal lives.
