ecological implications of the 18th and 19th century fur trade: a study of five hbc post's accounts
(2016)this research critically addresses the ecological implications of the 18th and 19th century fur trade and whether primary source material written and maintained by european fur traders can measure resource procurement ... -
assessing community forest resources to determine potential for biomass district heating in one rural and one remote first nation of northwestern ontario
(2016)the purpose of this thesis is to explore the feasibility of using biomass in rural and remote first nations for the purpose of supplying biomass district heating plants. the availability of forest resources, including the ... -
assessing the divide between humans and the natural world: effects of increased experience in natural areas
(2016)there is speculation as to whether humans are able to comprehend, appreciate, and protect natural environments when they have received minimal or no exposure to such areas. there are many speculative explanations for this ... -
oral contraceptives and emotional memory
(2015)previous research has suggested that oral contraceptive (oc) use is associated with altered memory for an emotional story. the current study further examined the extent to which ocs influence emotional memory by examining ... -
investigation of age-related changes in responsiveness of mirror neuron systems using fmri
(2016)observational learning, or the ability to learn a new skill by watching that same skill being performed by others, is one of the fundamental principles of motor learning. it is believed to be driven by a neural network ... -
an intra-site spatial analysis of the late paleoindian mackenzie i site (ddjf-9), near thunder bay, ontario
(2015)this thesis presents the results of the intra-site spatial analysis of the mackenzie i (ddjf-9) late paleoindian site, located ~30 kilometers east of thunder bay, ontario. the mackenzie i assemblage consisted of a wide ... -
trends in growth and soil nutrients following fire and logging
(2016)understanding the impact of natural and anthropogenic disturbance on soil fertility and tree growth is critical to the sustainability of forest management, yet there remains much uncertainty regarding how both harvesting ... -
genetic diversity and colonization patterns of onnia tomentosa and phellinus tremulae (hymenochaetaceae, aphyllophorales) in the boreal forest near thunder bay, northwestern ontario
(2016)forest health is impacted greatly by fungi, particularly those that cause disease in living trees. by examining genetic diversity within populations of pathogenic fungi and their patterns of colonization it is possible to ... -
effects of aging on the neural networks underlying visuomotor adaptation
(2016)visuomotor adaptation is the ability to correct movements in response to an error and becomes increasingly important during the aging process when assistive devices may become necessary. neuroimaging has observed age-related ... -
anxiety symptoms and precautionary behaviour across the menstrual cycle: the role of hormones
(2015)the present study examined the influence of hormones on obsessive-compulsive disorder (ocd) symptoms and related phenomena across the menstrual cycle. after exclusions, 223 participants (51 free-cycling women, 100 hormonal ... -
evaluating the attention network test and its ability to detect cognitive decline
(2016)the current study involved an evaluation of the attention network test (ant) as a neurocognitive tool for assessing fitness to drive in the senior population. the ant measures three distinct functions of attention: alerting, ... -
determining the predictability of acute mountain sickness using a regression analysis
(2010)ams (acute mountain sickness) is an altitude-related illness that occurs as a direct result of hypoxia. to date there is no consistent diagnostic measurement tool, leaving ams as a subjectively-measured illness. an exploratory ... -
effects of co2 elevation on the responses to flooding in black spruce (p. mariana) and tamarack (l. larcina) seedlings
(2016)anthropogenic activities have been increasing the atmospheric co2 concentration globally and the increase is predicted to continue to rise in the future. increased co2 has been shown to increase photosynthetic rates as ... -
functional niche differentiation in co-occurring congeneric plants
(2014)niche differentiation is argued as one of the mechanisms explaining species coexistence. despite their sessile nature, similar resource needs and traits to acquire and utilize resources closely related plant species coexist. ... -
supply chain management of the canadian forest products industry under supply and demand uncertainties: a simulation-based optimization approach
(2016)the canadian forest products industry has failed to retain its competitiveness in the global markets under stochastic supply and demand conditions. supply chain management models that integrate the two-way flow of ... -
application of biomass-based fly ash in the pressate of a thermomechanical pulping process
(2016)in the thermomechanical pulping (tmp) process wood chips are pretreated with steam prior to refining, and the resultant effluent (tmp pressate) is currently treated in the wastewater treatment facility of the pulp mill. ... -
using remote sensing for quantity analysis of chip pile inventory in mill yards
(2016)an integral part of proper wood chip inventory management is the ability to accurately monitor wood chip quantities. this thesis examines the use of a new method of capturing the volume of mill yard wood chip piles through ... -
piezoelectric energy harvesting with a nonlinear energy sink
(2016)energy transfer from one system to another system, or vice versa, is happening constantly in many processes with various forms. vibration in machines or structures can be considered as a form of energy transfer from a ... -
experimental study of vertical and oblique particle clouds in water
(2016)sand jets and particle clouds are common in many engineering areas such as marine bed capping, dredging, and artificial island construction. because of the wide range of their application, a better understanding of particle ...
