Associations Among Self-Reported Tick-Borne Disease Symptoms, Treatments & Diagnoses
In eastern Canada, deer ticks (Ixodes scapularis) carry a variety of bacterial (Borrelia burgdorferi, Anaplasma, Ehrlichia, Rickettsia) and protozoan pathogens (Babesia) that are responsible for more disease in humans than ... -
Structural determination and functional annotation of ChuS and ChuX, two members of the heme utilization operon in pathogenic Escherichia coli O157:H7
(2007-07-05)For pathogenic microorganisms, heme uptake and degradation is a critical mechanism for iron acquisition that enables multiplication and survival within hosts they invade. While the bacterial proteins involved in heme ... -
Benchmarking and development of webGIS in Ontario: implications for public use in planning
(2007-07-05)Governments use the Internet as another means to offer services to the public. One such service is to deliver GIS over the Internet, also known as webGIS. While some Ontario municipalities provide webGIS services, its ... -
Flexural behaviour of spun-cast concrete-filled fibre reinforced polymer tubes for pole applications
(2007-07-05)In this study, the feasibility of utilizing the spin casting technique with structural Fibre-Reinforced Polymer (FRP) tubes and eliminating steel reinforcement is explored for the first time. This would make spun-cast FRP ... -
Associations between abdominal adiposity, exercise, morbidity and mortality
(2007-07-05)The increasing prevalence of abdominal obesity worldwide poses a serious public health problem and hence, presents a target for research designed to improve the assessment or treatment of abdominal obesity. Specifically, ... -
The evolution of species' geographical range limits: an empirical test using two coastal dune plants, Camissonia cheiranthifolia (Onagraceae) and Abronia umbellata (Nyctaginaceae)
(2007-07-05)Every species has a limit to its geographic distribution. The problem is that we don’t really know why. Classical explanations propose that range limits occur where the ecological conditions overwhelm adaptation and ... -
Chemical Reaction Dynamics and Coincidence Imaging Spectroscopy
(2007-07-05)This thesis describes and develops two experimental techniques, Time Resolved Photoelectron Spectroscopy (TRPES), and Time Resolved Coincidence Imaging Spectroscopy (TRCIS), to study ultrafast gas phase chemical dynamics. ... -
Arsenic biotransformations in terrestrial organisms: A study of the transport and transformation of arsenic in plants, fungi, fur and feathers, using conventional speciation analysis and X-ray absorption spectroscopy
(2007-07-05)Arsenic taken up by plants and fungi from contaminated soils can subsequently be introduced into food chains. Given the toxic properties of some arsenic compounds, this may be a cause for concern. Much remains to be learned ... -
Ringdown spectroscopy in optical waveguides
(2007-07-05)Ringdown spectroscopy (RDS) is an absorption spectroscopic and detection technique that makes use of an optical cavity to realize a long effective pathlength through a sample and to render the measurement independent of ... -
A low feedback robust opportunistic scheduler and beamformer for MISO wireless systems
(2007-07-06)Opportunistic Beamforming is a promising scheme with potential usage in a variety of applications ranging from cellular audio/video communications to wireless mesh-networks. However, some aspects in this scheme are open ... -
An evaluation of the efficiency of lymphocytic choriomeningitis virus - nucleoprotein cross priming in vivo
(2007-07-11)During viral infections, CD8+ T cells only respond to a select few epitopes derived from the respective foreign pathogen. These epitopes can be organized into a hierarchy, based on their ability to induce T cell priming. ... -
Essays on the financial system and the transmission of monetary policy
(2007-07-11)This thesis studies the role of the banking system in several aspects of the macroeconomy, including the likelihood of financial crises, volatility of asset prices and the transmission of monetary policy. In chapter ... -
Design and development of an intelligent neuro-fuzzy system for automated visual inspection
(2007-07-18)This thesis presents work on the use of intelligent algorithms to solve a real-world machine vision problem in the automotive industry. Compared to commercial systems, the algorithm developed is both more robust to changes ... -
Effect of computer decision support system on antibiotic utilization in a complex continuing care and rehabilitation hospital
(2007-07-18)Background: Considerable amount of inappropriate antibiotic utilization has been observed in both acute and non-acute care hospitals. Literature has shown that strategies such as an order entry (OE) and computer decision ... -
Trait self-esteem moderates the effect of initiator status on emotional and cognitive responses to romantic relationship dissolution
(2007-07-18)Romantic relationship dissolution has been implicated in the onset of mood disorders (Monroe et al.,1999; Overbeek et al., 2003). It is therefore imperative that researchers and mental health professionals have an understanding ... -
The direct and moderating effect of bullying on adolescent health
(2007-07-19)In the last two decades, research has established a negative association between involvement in bullying and emotional health difficulties. Few studies, in comparison, explore the relationship between bullying and ... -
Optimal design in regression and spline smoothing
(2007-07-19)This thesis represents an attempt to generalize the classical Theory of Optimal Design to popular regression models, based on Rational and Spline approximations. The problem of finding optimal designs for such models can ... -
Study of pre-evaporation and matrix effects on multi-elemental analysis by ICP-TOFMS
(2007-07-19)The ultimate goal of this project was to improve the sensitivity and detection limits of inductively coupled plasma time-of-flight mass spectrometry (ICP-TOFMS) and then apply it to the speciation analysis of As. To this ... -
