Biogenic lead levels in human skeletal remains from the cemetery of the British Royal Navy hospital (1793-1822CE) at English Harbour, Antigua West Indies
Though lead has been known to be a cause of human poisoning since ancient times, it was a widely used metal. The relationship between ancestry or age and lead exposure in the Colonial period of Antigua, West Indies was ...
The impact of golf courses on nutrient dynamics from developed areas
Proper management strategies aimed at reducing the export of excess nitrogen and phosphorus to water bodies are fundamental for resolving nutrient pollution and eutrophication. Golf courses are more intensely managed than ...
Zooplankton community dynamics in the Trent Seven Waterway along Lake Simcoe and Lake Couchiching
The Trent Severn Waterway (TSW) is a 386km channel that connects Lake Ontario to Georgian Bay. There is a lack of information on the water quality in the nearshore region of the TSW specifically in regards to the planktonic ...
Cancer biomarker discovery using selected ion flow tube mass spectrometry
Lung cancer is one of the most common types of neoplasm and is a leading cause of death in Canada. Accurate early diagnosis is key to the effective treatment of the disease, however the current means to do so, such as ...
Phytochemical analysis of boreal forest flora of Northwestern Ontario, Canada
The following research document has been written in the format of a thesis by publication. As such, there is an introductory and concluding chapter to provide addition information and context to the scope of the study, ...
Effect of periphytic Escherichia coli and lake water bacterial population on the biofilm establishment of a Shiga toxin producing Escherichia coli O157:H7 strain
Biofilm studies Escherichia coli (E. coli) have typically focused on 0157:H7 in defined, laboratory medium. While there is value in such studies, they offer little in the way of explaining the behaviour and interactions ...
Biofilm formation of environmental and enterohemorrhagic Escherichia coli / by Stefan Moreira.

Protease production and in vitro growth of Sarracenia purpurea
Prey digestion in the insectivorous plant Sarracenia purpuero was investigated with consideration of three sources of proteolytic enzymes self-digestion by the prey, bacteria in the plant pitcher, and enzymes produced ...
Predicting mixing trends in mine-receiving waters using water quality modeling
Complete mixing of the water column of lakes is important to ensure that nutrients and dissolved oxygen are replenished and equalized throughout the lake. This ensures that organisms within the lake at all trophic levels ...
