Benthic uptake of mercury (Hg) governs bioavailability to fish yet there are still large gaps in our knowledge of what mediates this process. Without this information it is difficult to ascertain where Hg accumulation in the foodweb will be greatest. In the St. Lawrence River Area of Concern (AOC) at Cornwall, one contaminated zone (Zone 1) shows elevated Hg in yellow perch (Perca flavescens) and their prey items compared to those from other zones in the AOC. Greater availability of Hg to benthos due to unique physical features (large deposition of woodfibre deposits) of Zone 1 is hypothesized to account for this observation. In this study, amphipods (Gammarus fasciatus) and (Echinogammarus ischnus) were collected in Zone 1 using artificial substrates between June-September 2007, and Hg concentrations compared to those obtained in sediments and porewaters of surficial sediments, as well as methane gas evasion rates. Methylmercury (MeHg) concentrations in amphipods were significantly related to porewater total Hg (THg) and MeHg concentrations. No parallel relationship was found for sediment Hg concentrations or methane bubbling rates from sediments. Spatial and temporal trends in Hg bioavailability were evident from significant relationships with water column depth and temperature. Water column depth was associated with higher MeHg concentrations in amphipods and porewaters. Concentrations of porewater MeHg were above the detection limit in all of the June samples, the month which also coincided with highest amphipod MeHg concentrations. Finally, sediment organic matter may be influencing patterns of MeHg availability in Zone 1, and displayed a negative relationship to amphipod MeHg. Although bubbling from contaminated sediments did not directly correlate with amphipod Hg uptake, future studies should look at the influence of bubbling on the redistribution of contaminated sediment particles within the zone. / Thesis (Master, Biology) -- Queen's University, 2008-12-30 23:34:20.287

This study provides a new reading of Geoffrey Chaucer’s Prioress’s Tale and considers its purpose within the context of the Canterbury Tales. I argue that the Tale, as an exemplum, demonstrates the dangers of tale-telling, and exposes the moral discrepancies of the Canterbury tale-telling competition and the pilgrims’ use of stories as verbal assaults against one another. I argue that the Tale condemns the unchristian-like “actions” of the Christians within its frame as they respond to the clergeon’s murder; the Tale’s ending presents a cathartic response from this congregation, which indicates their understanding of the clergeon’s martyrdom. It also provokes a similar response from the Canterbury pilgrims, which serves to silence them, and to create a paradox that disrupts possible responses to the Tale. Further, Chaucer’s Retraction at the end of the Tales is intended to silence the poet’s critics through the creation of a similar paradox.

Electronic citizen participation has become a realistic option on all levels. Electronic participation includes: (i) citizen information systems about political decision making and law making, such as parlinkom.gv.at; (ii) discussion and deliberation platforms; and (iii) direct decision making in electronic voting, which is the focus of this research project. The high level of international experience in the field of electronic voting has been encouraging. In a semi-nal contribution, the Council of Europe published a set of minimum requirements for the legal, opera-tional and technical design of electronic voting sys-tems [CoE2004]. There is an ever-increasing number of pilot projects been conducted in several European countries. Practical experience is needed, not only to test the technology, but also to test the usability and user acceptance of such systems. This was the main ob-jective of this test.

Multiresolution analysis (MRA) has fairly recently become important, and even essential, to image processing and signal analysis, and is thus having a growing impact on image and signal related areas. As one of the most famous family members of the MRA, the wavelet transform (WT) has demonstrated itself in numerous successful applications in various fields, and become one of the most powerful tools in the fields of image processing and signal analysis. Due to the fact that only the scale information is supplied in WT, the applications using the wavelet transform may be limited when the absolutely-referenced frequency and phase information are required. The Stockwell transform (ST) is a recently proposed multiresolution transform that supplies the absolutely-referenced frequency and phase information. However, the ST redundantly doubles the dimension of the original data set. Because of this redundancy, use of the ST is computationally expensive and even infeasible on some large size data sets. Thus, I propose the use of the discrete orthonormal Stockwell transform (DOST), a non-redundant version of ST. This thesis will continue to implement the theoretical research on the DOST and elaborate on some of our successful applications using the DOST. We uncover the fast calculation mechanism of the DOST using an equivalent matrix form that we discovered. We also highlight applications of the DOST in image compression and image restoration, and analyze the global and local translation properties. The local nature of the DOST suggests that it could be used in many other local applications.
