(2012-11-10)knowledge of demographics, avalanche training, and avalanche safety practices of backcountry skiers in the mountain national parks of canada is of great importance to parks canada, the canadian avalanche association, ... -
one-step inactivation of rpos to investigate its role on escherichia coli o157:h7 biofilm formation and survival
(2009)homologous linear recombination using the recombinogenic capabilites of phage red genes exo, bet and gam, has been used increasingly to generate targeted gene replacements in gram-negative bacteria. -
in vitro detection of apoptosis using superparamagnetic iron oxide nanoparticles and molecular magnetic resonance imaging
(2010)superparamagnetic iron oxide (spio) nanoparticles have the potential to greatly expand current anatomical imaging techniques, specifically mri. spio nanoparticles targeted to phosphatidylserine (ps) have the potential to ... -
adsorption and microflotation studies with pure minerals and an arylhydroxamic acid collector
(2009)a study was conducted to understand the adsorption of n-hydrocinnamoyl-n-phenylhydroxyl-amine (hcnpha) on the surfaces of various pure minerals: sphalerite, pyrite, galena, chalcopyrite and quartz. hcnpha is a member of ... -
detection and characterization of dna damage
(2009)the dna molecule is constantly subjected to endogenous and exogenous sources of damage which if left unrepaired can lead to genotoxic and cytotoxic outcomes. these lesions have been implicated in the development of numerous ... -
utilization of coal biomass fly ash in the control and treatment of acid mine drainage
(2009)this study investigated the feasibility of using coal/biomass fly ash (cbfa) blended with various percentages of mine tailings, bentonite, and glacial till soil to control and treat acid mine drainage (amd). applications ... -
geochemical and toxicological investigation of the hogarth and caland pit lakes, former steep rock iron mine site
(2012-11-10)the closure of the steep rock iron mines near atikokan, ontario, canada in the late 1970's left behind an area of severe environmental concern. the subsequent flooding of the pit mines resulted in the formation of two ... -
pinning of magnetic vortices subject to multi-well potential in the ginzburg-landau theory of superconductivity
(2012-11-10)i will study the existence of multi-vortex solutions of the ginzburg-landau equations with an external potential on r2. these equations model the equilibrium states of superconductors: the external potential, w, represents ... -
the effects of the knowledge economy on women and resource dependent communities in northern ontario
(2009)historically women have often been confined to the home while their husbands were expected to earn a living to support their families. this was particularly true in resource communities as little job diversity existed, ... -
the education data issues model : using a knowledge mobilization framework to examine teachers' engagement with large scale assessment data as a means to enhance student learning
(2012-11-10)the purpose of this research was to examine the education data issues model (edim), as a useful conceptual framework through which to study teachers' engagement with large scale assessment data as a means to enhance student ... -
