Effects of nutrients conditions and solids retention time (SRT) on performance and membrane fouling of aerobic membrane bioreactors (MBRs)
(2015-10-21)This thesis investigated the effect of chemical oxygen demand (COD) to nitrogen ratio (COD:N) in feed on the biological performance of aerobic membrane bioreactor (MBR). Meanwhile, the effects of nutrients condition (COD:N ... -
Effects of oral contraceptives on daily self-ratings of positive and negative affect
(1997)The present study examined whether duration of oral contraceptive (OC) use could account for the inconsistent findings of previous studies on the relationship between affect and OC use. This study was the first to ... -
The Effects of Oral Contraceptives on Emotional Reactivity and Cognition
(2015)The purpose of this study was to investigate the effects of oral contraceptives (OCs) on emotional reactivity and cognitive ability. Previous research has suggested that OC users may experience blunted positive affect ... -
Effects of past grazing and trampling on soil nutrients at Stanley Hill Bison, Kakabeka Falls, Ontario
(2020)Global studies indicate that ungulates can have negative influences on soil quality and directly affect soil nutrient availability. This thesis examines the effects of past cattle grazing and current bison grazing on ... -
Effects of perceived competence and goal orientations on task persistence and affect in physical activity : a test of Dweck and Leggett's motivation theory
(1990)This study tested Dweck and Leggett’s (1988) social cognitive model of motivation in the physical domain. It investigated the effects of perceived competence (PC) and goal orientation (GO) on affective and behavioral ... -
Effects of Photoperiod, Soil Moisture and Soil Temperature on the Northward Migration Potential of Jack Pine under the Scenario of Doubled Atmospheric CO2 Concentration
(2016)Climate envelope models predict that boreal trees can potentially migrate northward by as much as 10º by 2100 as a consequence of the predicted climate change associated with the doubling of atmospheric CO2 concentration, ... -
The effects of plantation spacing on Pinus resinosa wood density variation and managing for increased carbon sequestration
(2020)Pinus resinosa is found throughout a large portion of eastern North America. Dating back to the early settlement era, wood utilization has varied from solely infrastructure to bioenergy and carbon sequestration. Although ... -
Effects of positive and negative emotional states on conjugate lateral eye movements and bilateral finger pulse volume
(1983)Lateral eye movement (LEM) and finger pulse volume (FPV) measures were taken while subjects responded to questions incorporating both a cognitive component, Visuo-spatia 1 or verbal processing, and an emotional component, ... -
Effects of post-budset fertilization on second-crop black spruce container stock
(1992)Second crop black spruce (Picea mariana (Mill.) B.S.P.) container stock is often treated with finisher fertilizer after the induction of budset. The objective of this experiment was to study the effect of three components ... -
Effects of postnatal experience on avoidance, shock sensitivity and open-field behavior of two selectively bred strains of rats
(1973)The effects of postnatal experience on avoidance, shock sensitivity, and open-field behavior were investigated in the Roman high avoidance (RHA/Lu) and the Roman low avoidance (RLA/Lu) selectively bred strains of rats. -
Effects of prenatal nicotine exposure on behaviorally conditioned immunosuppression in rats
(1993)Pregnant rats were administered nicotine (0.6 mg/kg/day) during different stages of pregnancy. Exposure occurred in either the first trimester (days 1-7), second trimester (days 8-14), third trimester (days 15-21), ... -
Effects of prescribed burning on mycorrhizal fungi in a pinus banksiana stand
(1997)The purpose of this study was to examine the effects of fire on mycorrhizal fungi in a Pinus banksiana stand. It was hypothesized that an optimal fire intensity leads to an increase in ectomycorrhizal colonization of ... -
Effects of process operating conditions on performance and membrane fouling in submerged anaerobic membrane bioreactors (AnMBRs)
(2016)Submerged anaerobic membrane bioreactor (SAnMBR) technology is becoming an attractive alternative for industrial wastewater treatment as it improves the biological process while allowing for the recovery of energy through ... -
Effects of radiation therapy knowledge and misconceptions on patient anxiety
(1996)Radiation therapy often produces considerable anxiety in patients. One reason for this anxiety is the uncertainty that often surrounds this treatment. Since studies have shown that many patients experience the most distress ... -
Effects of regular long term hemodialysis on serum electrolytes and parathyroid hormone levels
(1978)Regular long term hemodialysis is the accepted method of treatment for patients with advanced renal failure. While it is effective in maintaining a patient in reasonably good health for long periods of time many problems ... -
Effects of resistance training on selected physiological parameters
(1989)The literature presents contradictory statements concerning the effectiveness of free weights, isokinetic devices and plyometric exercises on the development of lower extremity power, and lean body mass {Coyle, Feiring, ... -
Effects of road construction cost in determining whether a block should be harvested in the summer or winter on the Romeo Malette Forest
(2022)Permanent and temporary forest roads are key infrastructures for the removal of raw forest products. Ensuring an efficient road network is laid out and proper construction methods are chosen will aid in reducing the total ... -
Effects of roads and log hauling on woodland caribou use of a traditional wintering area near Armstrong, Ontario
(1997)Increasing concern for the viability of forest-dwelling woodland caribou (Rangifer tarandus caribou) in Ontario has resulted in recommendations for more restrictive timber harvesting practices. Caribou populations have ... -
Effects of seed sources and fungi on ectomycorrhizal formation and growth of containerized tamarack seedlings
(1985)The objectives of this study were to investigate the host specificity of mycorrhizal fungi to tamarack (Larix laricina (Du Roi) K. Koch.) in pure culture synthesis and to examine the effects of seed sources and fungal ...
