Accessory rare metal mineralization in the Coldwell Alkaline Complex, Northwest Ontario
(1990)Accessory rare metal mineralization has been investigated in seven lithologies in intrusive Centres I and III of the Coldwell alkaline complex. All units contain minerals that are enriched in a suite of granitophlle ... -
Accommodating Students on Classroom and Large-scale Assessments: Teachers’ Perspectives and Validity Issues
(2015)The objective of this research was to examine teacher perspectives of accommodation practices in the classroom, on large-scale assessments, and their effect on the validity of large-scale assessment data in Ontario ... -
Acoustic properties of four central boreal tree species for potential use in instruments
(2023)In resonance wood, acoustic velocity, density profiles, and ring characteristics play an important role. Multiple factors cause variation of these properties, like the difference between juvenile wood and mature wood, ... -
Acoustic wave propagation testing to determine quality in timber and timber products
(2020)Assessing and grading of raw materials in the timber industry is a key factor in the maximization of extracted value. Several different approaches are utilized to measure the quality of standing timber and sawn lumber. ... -
Acoustoelectric effect in semiconductors
The possibility of electron temperature decreasing below the lattice temperature in the presence of an external electric field (electron cooling) has been pointed out by Paranjape and Ambrose (1964). In the present works ... -
Activity of liposomal taxol against breast cancer cells / by Melanie Heney.
(2007)Taxol (paclitaxel) is one of the most effective chemotherapeutic agents used for the treatment of multiple cancers, including breast, ovarian, and, non-small-cell lung cancer. However, development of taxol resistance with ... -
Adaptability in moose (Alces alces L) : habitat selection in two landscapes in Newfoundland, Canada
(2014-01-22)Moose (Alces alces [L.]) exist circumglobally and in a vast array of different habitats. I explore differences in habitat selection in relation to differences in availability of forest stands by habitat type and number of ... -
Adaptations of Euro-Canadian schools to Inuit culture in selected communities in Nunavut
(2001)This study explores educators' current and desired 'adaptations' of Euro-Canadian schools to Inuit culture, in five communities in one region of Nunavut Communities ranged in size from 800 to 3500 residents, of which on ... -
Adapting modular structures for healthcare applications
(2022)COVID-19 has highlighted many vital factors to consider when it comes to the healthcare systems. Some challenges such as personnel, equipment, and space demands. Personnel demand can be met by calling retired doctors and ... -
Adapting reproduction: portrayals of sex, birth, and bodies in four early modern women's metaphors for writing
(2014-01-22)The metaphor for writing as reproduction was common in literature by both men and women in the early modern period. Indeed, Donald W. Foster argues that the comparison between texts and children, “is the single most frequent ... -
Adapting the Ontario teacher performance appraisal manual to video-based teacher assessment / by Eric Fredrickson.
(2008)This study asks if a teacher appraisal tool, the Ontario "Teacher Performance Appraisal Manual" (TPAM) can be modified toward the assessment of pre-service teacher competencies as viewed in archived videoconference lessons. ... -
Adapting to change, perceptions and knowledges in the involvement of Aboriginal peoples in forest management : a case study with Lac Seul First Nation
(2009)This study examines the involvement of Aboriginal peoples in forest management and their perceptions and understandings of the forest, forest management, participation, consultation and Aboriginal and Treaty rights in ... -
Adaptive almost disturbance decoupling for a class of nonlinear differential-algabraic equation systems
(2016)A class of engineering systems is modeled by Differential Algebraic Equations (DAEs), which are also known as singular, descriptor, semistate and generalized systems. In the chemical engineering processes, the differential ... -
Adaptive and Maladaptive Outcomes of Perfectionism and Changes After Mindfulness Training
(2015)Considerable debate exists in the personality literature regarding the adaptiveness versus maladaptiveness of perfectionism. Study 1 (N = 240) involved a two-phase design to examine main and interactive effects of perfectionism ... -
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 ... -
Adaptive backstepping based nonlinear control of an interior permanent magnet synchronous motor drive
(2005)Permanent magnet synchronous machines (PMSM) have shown increasing popularity in recent years for industrial drive applications due to the recent developments in magnetic materials, power converters, and digital signal ... -
Adaptive backstepping based online loss minimization control of an induction motor drive / by San Woo Nam.
(2006)The efficiency of an induction motor (IM) can be improved by the optimum selection of a flux level in the motor. Among the numerous loss minimization algorithms (LMA), a loss-model-based approach offers a fast response ... -
Adaptive backstepping control of quadrotors with neural-network
(2018)A quadrotor is a type of unmanned aerial vehicles. It has been widely used in aerial photography. The quadrotor has the capability of vertical takeoff and landing, which is very useful in small or narrow areas. The ... -
Adaptive control of a parallel robot via backstepping technique
(2006)Parallel robots have attracted more and more attention in recent years due to their kinematical and mechanical advantages. However the complicated high nonlinear model with unknown parameters and singularities make the ...
