Floristic structure, composition and depth of edge influence at buffer and wildfire edges along small boreal streams
(2009)Within the boreal forest of northwestern Ontario clearcutting and fire are the most common edge-creating disturbances. Along streams, wild fire consumes the majority of trees to the edge of riparian zones. However, forest ... -
Adult Attention-Deficit Hyperactivity Disorder (ADHD) and the isolation of low and high end component operations in temporal processing and time perception
(2009)Evidence has shown that Attention-Deficit Hyperactivity Disorder (ADHD) is associated with deficits in temporal processing and time perception (Toplak & Tannock, 2004). Current literature, however, focuses on time perception ... -
Development of key components of a nitrogen budget for a forested watershed on the Canadian boreal plain
(2009)This investigation, which took place as part of the Forest Watershed and Riparian Disturbance (FORWARD) study in west-central Alberta on the Boreal Plain, measured key components of a nitrogen (N) budget in a relatively ... -
Understanding levels of social economy development : an examination of Northern Canadian communities
(2009)This study offers a preliminary analysis of the role specific social factors have on social economy development in the Yukon, Northwest Territories and Nunavut. Because of the marked differences in levels of social economy ... -
Adaptive and phenotypic responses of white birch provenances to climate variations
(2009)Trees have adapted to their local climate, but with changes in the climate may currently, or in the near future occupy climates that are sub-optimal for growth and survival. The goal of current reforestation is therefore ... -
One world, one dream : comparisons of the newspaper coverage of the 2008 Beijing Olympic and Paralympic Games
(2009)This study compared and explored the newspaper coverage of the 2008 Beijing Olympic (OG) and Paralympic Games (PG) by a Canadian newspaper, The Globe and Mail. The methodology for this study was mixed methods design which ... -
Assessing above- and belowground competitive effects in pure and mixed stands of jack pine (Pinus banksiana) and black spruce (Picea mariana)
(2009)Ecological principles of niche, competition and competitive reduction suggest that competition in mixed stands composed of pine and spruce may experience positive interactions through (1) vertical stratification of canopy ... -
Design and control of a 10 DOF biped robot
(2009)Compared to wheeled robots, biped robots have their advantages. Biped robots have better mobility. Biped robots can walk in human environments, such as rough terrain and the place that contains obstacles, and can also climb ... -
Reducing the environmental impact of the flotation of sphalerite : an alternative reagent scheme
(2009)N-Hydrocinnamoyl-N-phenylhydroxylamine (HCNPHA) was found to float sphalerite without activation by copper sulphate. However, concomitant flotation of sulphidic gangue minerals, such as pyrite, significantly reduced the ... -
Ecophysiological responses of white birch seedlings to soil temperature and phosphorus supply under current and doubled carbon dioxide concentration
(2009)To investigate the responses of some physiological and morphological traits to different soil temperature and phosphorus supply under current and doubled carbon dioxide concentration ([CO2]), white birch (Betula papyrifera ... -
Demographic, reproductive, and psychosocial predictors of mood change in the postpartum period
(2009)The purpose of this study was to examine demographic, reproductive, and psychosocial predictors of mood change in the postpartum period. In a prospective design, 33 women completed either an online or paper and pencil ... -
The Incidence of invasive Haemophilus influenzae disease in Northwestern Ontario
(2009)Prior to the late 1980s, Haemophilus influenzae type b (Hib) was the most common cause of meningitis, epiglottitis, and other invasive bacterial infections in young children. The introduction of the conjugate Hib vaccines ... -
Women at the heart of the social economy : what motivates women to work in the social economy in Whitehorse, Yukon?
(2009)This thesis looks at the importance of women in the social economy in Whitehorse and the motivations influencing women's participation in this sector of the economy. Women's involvement in the traditional economy has been ... -
Measuring S100B in concussed athletes following a maximal aerobic fitness test
(2009)An objective biological test to measure concussion may provide further insight into a player's decision to return-to-play. Protein S100B is a calcium-binding protein that has been studied as a sensitive biomarker of central ... -
Examining the effects of trial order and conditioning on the covert orienting of visual attention task (COVAT)
(2009)It has recently been reported by Deller (2006) that the mechanisms of early facilitation followed by late inhibition of return (IOR) attenuated upon ANS activation, manipulated through head-down neck flexion (HDNF). The ... -
Regeneration dynamics after fire and clear cutting in boreal mixedwoods
(2009)Emulation of natural disturbance processes and their effects is important to maintain the structure and composition of managed forests. In boreal mixed forests, clearcutting has been considered as management practice ... -
Catalytic decomposition of ammonia and tar for hot gas cleanup in biomass gasification using activated carbon supported catalysts and natural limonite ores
(2009)Biomass gasification produces a gas (or syngas) containing primarily CO2, H2, CO, CH4 and (C2+C3), as well as some contaminants such as tars, NH3, H2S and SO2. In order to achieve better efficiencies of the syngas applications, ... -
The Infant feeding experiences of urban Aboriginal mothers : implications for universal breastfeeding policy
(2009)In Canada breastfeeding rates are lower among marginalized women and studies have demonstrated that successful and exclusive breastfeeding for the recommended six months frequently requires an extensive support system, one ... -
Characterization and utilization of fly ash derived from the co-combustion of biomass and coal as a mineral admixture for ordinary Portland cement
(2009)Co-firing coal with renewable/waste biomass for power generation can mitigate the atmospheric discharge of pollutants (e.g., SO2) and green-house gases. Wide-spread application of this technology is impeded, however, by ... -
Inuit youth migration from Iqaluit to Ottawa
(2009)With a public perception that Inuit youth are leaving the North, it is important to improve our understanding of migration in the Circumpolar North. The purpose of this pilot study is to identify, investigate and critically ...
