Comparison of heart rate recovery from physical and mental stress
(1990)The present study evaluated a new paradigm for identifying individuals who show exaggerated, delayed physiological recovery following mental stress. Siibjects first performed a mental task, a face-to-face quiz, wliile ... -
Comparison of innovated thermoplastic polyurethane and commercial helmet lining technology in mitigating concussions as measured by linear accelerations and risk of head injury during simulated horizontal impacts to the head
(2020)Advances in helmet designs and technology have not completely eliminated the incidence of mild traumatic brain injuries (mTBI) in the sport of ice hockey. One issue that concerns researchers is that the vinyl nitrile ... -
Comparison of intrinsic motivation scores for two groups of pre-adolescent athletes
(2004)In order for an individual to successfully learn and execute a new movement skill it is expected that they will not only have achieved a specific level of understanding (i.e., cognition), but they will also have had to ... -
Comparison of methods to determine the carbonation depth in fly ash blended cement mortars
(2014-01-22)Carbonation negatively affects the durability of steel-reinforced concrete structures by causing a decrease in pore solution pH, thus facilitating corrosion which eventually leads to cracking and spalling. Different ... -
Comparison of oxygen consumption and selected kinematics between and within the 1-skate, 2-skate and offset techniques
(2001)The 1-skate, 2-skate and offset techniques are the three most prevalent skate-skiing techniques used during cross-country ski racing. Although kinematic differences at maximum velocity have been observed between techniques ... -
Comparison of Picea mariana, Abies balsamea, Betula papyrifera, Populus tremuloides for the production of wood pellets
(2023)Scientists and international organisations agree that wood pellets are a type of biofuel that is better for the environment than fossil fuels. Wood pellets are produced from the residues in sawmills, ground logs and is ... -
Comparison of policy and legislation to protect nature reserves in Canada and China
(2018)Many animals and plants are extinct because of human activities. The nature reserve is the most effective way to protect natural resources and wildlife. In this paper, I reviewed policies to protect nature reserves in ... -
Comparison of post-harvest sample designs to assess impact to organic forest soils in eastern Manitoba
(2001)Five sampling methods were developed, tested, and compared to assess soil impact from harvesting equipment on organic sites in unfrozen condition. This study pointed to the gap in the literature for such a sample design. ... -
Comparison of risk factors and criminogenic need among incarcerated young offender, probationary young offender and non offender samples
(1995)This research examined some of the risk/need factors that discriminate offending from non-offending youth employing three groups of adolescents at different points on the crime continuum. Non-offenders (n=30), probationary ... -
Comparison of spatial vegetation patterns following clearcuts and fires in Ontario's boreal forests
(2000)The goal of this study was to compare spatial vegetation patterns, based on Landsat TM data, within post-clearcut and post-fire disturbances. Landscapes disturbed during the four decades prior to the collection date of ... -
Comparison of stratification and scarification methods of Sorbus decora, Vitis riparia, and Rhus typhina
(2022)This thesis investigates the effectiveness of three methods in breaking seed dormancy of Sorbus decora, Vitis riparia, and Rhus typhina. The treatment methods studied were mechanical scarification with sandpaper, ... -
A comparison of the effectiveness of ground versus aerial chemical site preparation
(2020)Silviculture operations in northwestern Ontario can include the use of chemical site preparation to remove competing herbaceous vegetation to promote the establishment of conifer seedlings. Aerial and ground applications ... -
A comparison of the hydrothermal alteration systems around the Mo-hosting White Pine intrusion, Utah, and the Buckingham Porphyry, Nevada
(2015)The White Pine Fork Mo porphyry has an estimated resource of 16 Mt of Mo at 0.1% Mo. The host intrusions are K-feldspar- and quartz-porphyritic monzo- to syeno-granites characterised by LREE enrichment, fractionated HREEs ... -
Comparison of the late quaternary sedimentary sequence and paleomagnetic record of the North Bay outlet and a Baffin Island fiord
(1983)The lithology of the Late Quaternary lacustrine sequences of five lakes in the North Bay area differs from one lake to another. However, chronostratigraphically equivalent sections of cores taken from the same lake ... -
Comparison of the on-hand and off-hand straight spikes in volleyball
(1980)The purpose of this study was twofold: 1) to examine the differences between the on-hand side and off-hand side spikes in volleyball in terms of velocity and accuracy, and 2) to evaluate the relationship of the angle ... -
Comparison of the pre-settlement and present diversity of the forests of Central Ontario
(2000)Original Crown Survey notes were used to infer the European pre-settlement forest diversity condition in the management units of Algonquin Park, French-Severn, Nipissing and Temagami in central Ontario, Canada. This ... -
A comparison of the quality of farm and forest soils in the Emo-Rainy River District of Northwestern Ontario
(2020)This thesis explores different aspects of the qualities of soils found in a farmer’s hayfield and nearby forested areas on the West side of Emo, Ontario. Soil qualities of a forest and hayfield sites with multiple plots ... -
A comparison of the quality of hayfield and pasture soils on a Northwestern Ontario farm
