In this thesis I explore the ways in which twenty-first century Americans have access
to Geoffrey Chaucer and his works. I look at issues surrounding Chaucer within the
canon debate, high school history and literature textbooks, and Chaucer in popular
culture, such as in movies like A Knight's Tale. I...
Catalase HPII from Escherichia coli, is a mono-functional catalase responsible for preventing the formation of reactive oxygen species in the cell. Its active site is representative of most mono-functional catalases, making it a good model for mechanistic studies. The role of the heme-binding tyrosine was investigated by replacing Tyr415 with...
In recent years, microRNA’s (miRNA’s) have emerged as important in regulating gene expression. Fluctuations in their levels are associated with the up or down-regulation of tumor-suppressor genes and oncogenes. Thus, the ability to visualize changes in miRNA is an important step in understanding cancer emergence and development. The Burrows group...
During the 1970’s the United States experienced several periods of high inflation that have been at least partially attributed to positive oil price shocks. The effectiveness of the Organization of Petroleum Exporting Countries at controlling the price of oil has varied over time, as well as the responsiveness of U.S....
Sea-level and ice-sheet databases have driven numerous advances in understanding the Earth system. We describe the challenges and offer best strategies that can be adopted to build self-consistent and standardised databases of geological and geochemical information used to archive palaeo-sea-levels and palaeo-ice-sheets. There are three phases in the development of...
Mixia osmundae (Basidiomycota, Pucciniomycotina) represents a monotypic class containing
an unusual fern pathogen with incompletely understood biology. We sequenced and analyzed
the genome of M. osmundae, focusing on genes that may provide some insight into its
mode of pathogenicity and reproductive biology.
Mixia osmundae has the smallest plant pathogenic basidiomycete...
