Although runways are critical components that make up an airport, few studies have examined their orientations and operations. This is further compounded by the fact that runway layout design and/or configuration are so complex yet they play a vital role in the airport's daily operation, capacity, and safety. In this study, I wish to apply GIS techniques, a wind rose model, and a noise distance decay model to achieve two specific objectives: (1) to determine the effectiveness of runways in terms of its orientation, design, and physical layout; and (2) to analyze any socioeconomic and environmental impacts associated with the use and development of O'Hare Chicago International Airport (ORD). The economic impact of this airport that was reviewed includes job employment, annual development, movement of goods and services and tourism. The study highlights the environmental impacts such as noise, lake effects, compatible land use, and other significant factors in relation to the airport and surrounding communities. The noise distance-decay model shows that aircraft noise levels decompose at about 800 feet (243m) from the O'Hare runways. Areas close to the airport have a 70db noise level and there are non-homogenous patterns between the day and night sound levels and the distance from the runways. The wind rose model shows that the wind blowing at O'Hare airport has a southern directional bias only two of the eight runways meet the criteria of a northeast/southwest direction. The directions of the winds are predominantly southerly headings and wind speeds are greater than 7 m/s. The integration of rule-based runway networks and the wind rose model results allowed for a visual analysis and comparison of runway networks. The integration enabled the analysis of the wind direction in relation to the landing or takeoff of aircrafts. The final interpretation of this result requires caution as it suggests that the use of daily wind events would provide a better outcome. Although this study has suggested a GIS-based strategy and wind rose model with key four elements it still requires further refinement. Future work should plan to include more analytical models/optimization methods that accounts for most factors that determine the effectiveness utilization of runways.

abstract: The topos of home is fraught with ideological baggage. This piece works alongside others that labor to rework home as a space for rhetorical topos. I spend the majority of my text analyzing three books from which I explicate the topos of "home." These books are Mike Rose's 1989 work Lives on the Boundary: A Moving Account of the Struggles and Achievements of American's Educational Underclass, Victor Villanueva's 1993 Bootstraps: From and American Academic of Color, and Ellen Cushman's 1998 The Struggle and the Tools: Oral and Literate Strategies in an Inner City Community. I've chosen these books for two interrelated reasons. First, these texts aided in establishing working-class rhetoric as a field of study within the paradigm of rhetoric and composition. And second, in their individual ways, each of these books is anchored in a profound sense of "home." Each of the texts also experiments and resists scholarly conventions to include some autobiographical passages. Central to these passages is the topos of home, a theme that both enriches the author's autobiographical account and informs his or her theory forwarded in that work. These features add fruitful theory building to both the authors' individual texts and the paradigm as a whole. I ground my work in working-class theory, analyzing the work of Steve Parks, Nick Pollard and Nancy Welch, alongside scholarship that analyzes those labeled as "other" in higher-level academia. The stories that Parks, Pollard and Welch quote, the works of Rose, Villanueva, Cushman and even myself, all work toward discussing and creating not only a "home" for working-class academics but also room for more working-class research and theory-building. As I argue in this project, through these very acts of rhetorical/scholarly experimentation, Rose, Villanueva, and Cushman defied conventional standards for what counts as "good scholarship" in order to initiate a scholarly trajectory for working-class rhetoric in the academy. These authors' discussions of the "home" -specifically personal and political references to working-class homes--were instrumental tools in creating a public homeplace and space for further working-class theory building for rhetoricians in our field. / Dissertation/Thesis / M.A. English 2012

The fleshy hips of the briar rose, Rosa rugosa were cultured on a modified medium developed by Gamborg (1963) to produce callus and suspension cultures. These cells were very light, almost white. Reduced ascorbic acid, determined by the 2,6-dichlorophenolindophenol titration method, was found in the suspension cultures. This finding prompted an investigation into culture techniques for obtaining an optimum concentration of ascorbic acid. During the growth of the cells, the pH rose and ascorbic acid concentration increased after the sixth day. Age of culture was also an important factor as cultures older than three or four weeks contained virtually no ascorbic acid. Possible precursors of ascorbic acid in plants were added to cultures and their effect on the ascorbic acid level was determined over a period of twenty-four hours. D-glucose, D-(-)-levulose, D-galactose and D-glucurono-ɣ-lactone caused no increase. L-gulono-ɣ-lactone brought about a slight increase and a comparatively large increase was obtained with L-galactono-ɣ-lactone. Confirmation for the latter was obtained using the 2,4-dinitrophenylhydrazine method to rule out the possibility or microbial contamination and to be sure that another metabolite was not responsible for the increased reducing capacity of the system. Omission of myoinositol from the vitamin solution of the medium decreased total cell yield but had no effect on the level of ascorbic acid. Decreasing the sucrose content of the medium by one-half caused a sharp decrease in ascorbic acid concentration, indicating that an adequate supply of sugar is a prerequisite for optimum production of ascorbic acid. Growing liquid suspensions under controlled illumination resulted in increased ascorbic acid values with each successive transfer; however, total cell yields decreased each time. In addition, there was no evidence of chlorophyll production in the cultures. This exploratory work shows that ascorbic acid is present in the tissue culture of Rosa rugosa. Therefore, tissue culture may be useful for elucidating the complete pathway for ascorbic acid production which is as yet still unclear. This information coupled with the effects of altering the physical environment of the cells may direct cultures of Rosa rugosa to produce ascorbic acid in quantities that would make its recovery industrially attractive. / Land and Food Systems, Faculty of / Graduate

La rose est la fleur la plus vendue au monde. Elle a une place prépondérante en horticulture et dans l'industrie des parfums, c’est pourquoi des études visant à préciser les mécanismes cellulaires d’émission du parfum ont été entreprises. Des travaux antérieurs ont permis d'émettre une hypothèse selon laquelle le parfum serait véhiculé par des vésicules lipidiques. Nos observations ont montré que dans les pétales de roses, les vésicules sont composées d'une matrice centrale où se concentrent les triglycérides entourés d'une membrane à un seul feuillet phospholipidique. Ces caractéristiques étayent la théorie selon laquelle les vésicules lipidiques purifiées de pétales de rose sont des oléosomes. Cependant, l’oléosine, protéine marqueur de ce compartiment, n'a pas été identifiée. Ces vésicules sembleraient être impliquées dans le stockage des enzymes des voies de biosynthèse des parfums et des parfums eux-mêmes. Le gène RhPAAS, impliqué dans la voie de biosynthèse du 2-phényléthanol, a également été étudié. Des travaux préliminaires montrent que le QTL majeur expliquant la présence de 2-phényléthanol chez Rosa wichuraiana et le gène RhPAAS sont localisés sur le même locus dans le groupe de liaison B7. La modulation de l'expression du gène RhPAAS a donc été une hypothèse pour expliquer la présence ou l’absence de 2-phényléthanol dans la population HW. Au stade BJO, seuls les descendants produisant beaucoup de 2-phényIéthanoI, expriment RhPAAS. Le transcrit est accumulé au stade BJO dans les pétales c'est-à-dire avant le maximum d’émission du parfum. L’allèle a1 lié à la production du 2-phényléthanol a été identifié tandis qu’un autre allèle a2 s'exprime uniquement chez les roses produisant très peu de 2-phényléthanol / The rose is the most sells flower around the world and it has a prominent place in horticulture and in the perfume industry, which is why studies to clarify the cellular mechanisms of perfume emission have been undertaken. Previous work has enabled to deliver a hypothesis is that the scent would be mediated by lipid vesicles. Our observations showed that the vesicles are composed of a central matrix with a TG concentrate surrounded by a single sheet phospholipid membrane. These patterns support the theory that oil bodies purified from rose petals are oleosomes. However, the oleosin, a marker protein of this compartment has not been identified. The vesicles appear to be involved in the storage of biosynthetic pathways enzymes of perfumes, and fragrances themselves. The RhPAAS gene, involved in the biosynthesis of 2-phenylethanol, was also studied. Preliminary work showed that the major QTL explaining the presence of 2-phenylethanol to Rosa wichuraiana and the RhPAAS gene are localized on the same locus in linkage group B7. The modulation of gene expression RhPAAS has been a hypothesis to explain the presence or absence of 2-phenylethanol in the population HW. Indeed, at BJO stage, only the descendants producing much 2-phenylethanol, expresses RhPAAS. The transcript is accumulated in petals at BJO stage that is to say before the maximum emission of fragrance. The a1 allele linked to the production of 2-phenylethanol was identified while another allele is expressed only in roses producing few 2-phenylethanol
