Nature and structure of DNA through the process of degradation
(2004)The identification and characterisation of DNA damage is of great importance to molecular research and has significant implications for clinical and forensic fields. From the moment of cell death, DNA incurs many forms ... -
Perceived stress among Alzheimer support group members : a broader perspective
(2004)This study examines the experience of Alzheimer caregiver support group members in relation to their perceived levels of stress. Thirty-three participants from the six Alzheimer Society sites in the jurisdiction of ... -
Black spruce regeneration in Kalmia dominated sites : effects of mycorrhizal inoculation and forest floor mixing
(2005)Study area : Terra Nova National Park, 90 km southeast of Gander, Newfoundland. -
Small-scale disturbance and vegetation dynamics in trembling aspen dominated forests in northeastern Ontario
(2004)The scientific understanding of boreal forest stand development and vegetation dynamics has been well documented with respect to stand-initiating disturbances; however, the role of subtler disturbance events has received ... -
Edge effects at clearcut, fire and riparian buffers in the boreal forest of Northwestern Ontario
(2004)In the boreal forest of northwestern Ontario clearcutting and fire are two common edge-creating disturbances. Fundamental knowledge regarding the ability of fire and clearcut edges to minimize edge effects, preserve ... -
Adaptive optimizer based on the sequential simplex method applied to the control of a thermo-mechanical pulping screening room
(2004)An adaptive optimizer is designed for control of multi-variable processes where the operating characteristics of the plant are time varying. Based on the original sequential method for static applications, the modified ... -
Teachers' perspectives on the implementation of the Ontario elementary school science curriculum
(2005)This study examined the implementation of the Ontario elementary school Science and Technology curriculum from the perspective of nine grade 8 teachers of varying experience and specialization. The questions which this ... -
Attitude stabilization of a quadrotor aircraft
(2004)The quadrotor aircraft has seen a growing interest in the research community over the past few years, with a focus on modeling and control however. Early rotating wing aircraft pioneers designed similar four-rotor aircraft ... -
Experimental evaluation of some classical and adaptive iterative learning control schemes on a 5DOF robot manipulator
(2004)In many process industries (e.g., VLSI production lines, Automotive industries, IC welding process, inspections, manipulations), robot manipulators are used to perform the same tasks repeatedly over a finite time interval. ... -
Core areas of habitat use : the influence of spatial scale of analysis on interpreting summer habitat selection by moose (Alces alces)
(2005)I investigated summer habitat selection patterns within the home ranges of 60 GPS-collared adult female moose (Alces alces) in northwestern Ontario. I developed a model that identified the ‘summer’ period for moose and ... -
Genetic variation in physiology and growth under ambient and elevated CO2 concentrations in four provenances of Populus tremuloides from Northwestern Ontario
(2003)Trembling aspen (Populus tremuloides Michx.) is the most widely distributed and probably most genetically varied woody species in North America. Four provenances of trembling aspen seedlings from northwestern Ontario ... -
Pilot study to measure the relationship between myocardial infarction and periodontal disease : application of a case-control design
(2003)Recent public health reports have identified Northwestern Ontario and Thunder Bay for increased risk of coronary heart disease among several cohorts. The present study investigated the relationship between myocardial ... -
Constructing local culture in a near media monopoloy
(2003)The main objective of this thesis is to examine how the local radio news media in Thunder Bay construct local culture. Two paradigms are used to explain this process: instrumentalism and structuralism. Although other ... -
Applications of satellite remote sensing to develop forest inventory for strategic-level planning
(2003)Forest inventory is the fundamental base information for most decision making processes in today’s forest management planning. Recently in Ontario, with increasing industrial involvement, new environmental and multiple ... -
Habitat use, movement patterns, and home ranges of coaster brook trout in Nipigon Bay, Lake Superior
(2004)Coaster brook trout are one of two salmonine species native to Lake Superior. Abundant and widely distributed in Lake Superior a century ago, they have been reduced to a few remnant stocks due to exploitation and habitat ... -
A longitudinal mitochondrial DNA analysis of modern human hair samples from the Anyang region of China : implications for ancient DNA research
(2003)In 1998, Dr. E. Molto was selected to conduct pilot research on the Hei Heru, Shang Dynasty site in Anyang, China. A major component of this research is the ancient DNA analysis o f human remains recovered at Anyang. ... -
Movements, survival and habitat use by elk (Cervus elaphus) reintroduced to Northwestern Ontario
(2003)Once native to Ontario, eastern elk (Cervus elaphus canadensis) occupied much of the deciduous forest biome of eastern North America. However, increasing human settlement, as well as demands for meat and agricultural ... -
ESL learners perceptions of the cultural components in their English learning
(2003)This qualitative study investigated English as a Second Language (ESL) learners' perceptions of the nature and influence of immersion in a predominantly English culture on their English learning. The participants in the ... -
Anatomical and physical wood property variation and juvenile wood distribution in a single stem of trembling aspen
(2003)The variation of fiber length, vessel element length, relative density, ring width and the distribution o f juvenile wood within the stem of a 62-year-old trembling aspen (Populus tremuloides Michx.) were studied. Samples ... -
Thin gold films grown in ultra high vacuum on mica substrates
(2003)In-situ evaporation was used to deposit thin gold films (640 A) on mica substrates held at room temperature. The samples were characterized by Auger Electron Spectroscopy (AES) and Scanning Tunneling Microscopy (STM) ...
