A comparison of decomposition of jack pine and trembling aspen wood blocks by eight wood decay fungi
(2017)Decay is an important component of the carbon cycle, as it breaks down wood and releases the stored carbon back into the atmosphere. White rot, brown rot, and soft rot are all types of decay which initiate this process. ... -
Comparison of forest fire regimes between Heilongjiang in China and Ontario
(2017)This research summarizes and compares the differences in forest fire regimes in the provinces of Ontario, Canada, and Heilongjiang, China, as it relates to fire suppression techniques, human activities, and climate change. ... -
Comparison of fructose and glucose ingestion before and during endurance cycling to exhaustion
(1995)The aim of this study was to compare the effect of pre-exercise and exercise ingestion of fructose and glucose during prolonged cycling exercise. The primary purpose was to determine if ingesting fructose before and ... -
Comparison of group and individual approaches : to the cognitive-behavioral treatment of bulimia
(1987)The current study is a comparative investigation of two treatment approaches to the eating disorder bulimia, A cognitive-behavioral group therapy approach was compared to a cognitive-behavioral individual psychotherapy ... -
Comparison of growth intercept and site index models of black spruce plantations and natural stands in Northern Ontario
(2008)Black spruce (Picea mariana Mill. B.S.P.) is one of the most important tree species in Canada, both ecologically and commercially. The forest industry has steadily increased efforts to artificially regenerate areas that ... -
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
