the economic feasibility of replacing diesel with renewable energy resources in remote first nation communities in northern ontario
(2017)ontario has many first nation communities in the remote northern region that use diesel fuel to generate part or the whole of their energy requirements. there is a huge financial and environmental cost associated with ... -
bioenergetic evaluation of a whole-lake nanosilver addition on yellow perch (perca flavescens)
(2018)nanosilver (nag) is an antibacterial and antimicrobial agent. its wide use in hundreds of commercial products and industrial applications suggests a high potential for release into the environment. previous research indicates ... -
lignin-based flocculant and dispersant for wastewater treatment
(2018)the wastewaters produced from different industries contain fine and charged suspended particles and other impurities. today, the removal of these colloidal particles from the wastewater has become a serious challenge for ... -
first nation observations and perspectives on the changing climate in ontario's northern boreal: forming bridges across the disappearing "blue-ice" (kah-oh-shah-whah-skoh siig mii-koom)
(2017)forests can have significant potential to mitigate climate change. conversely, climatic changes have significant potential to alter forest environments. forest management options may well mitigate climate change. however, ... -
carbon storage dynamics and tree growth response to species diversity in boreal forests
(2018)the boreal forest plays a critical role in regulating the global carbon (c) cycle. both wildfire and harvesting affect ecosystem c. however, the long-term recovery of forest c storage with a diverse range of overstory ... -
towards identification of progressive damage in structures under non-stationary excitation
(2018)monitoring and retrofitting of large-scale infrastructure is of paramount importance specifically when they are subjected to natural hazards like strong wind, severe earthquakes or man-made excitation. once the rich ... -
efficacy of bacteria and caffeine as indicators of anthropogenic waste in freshwater systems
(2018)with urban sprawl and intensified agriculture, nutrient loading of waterways has become a pressing issue across southern ontario. domestic wastes are more likely than other wastewater sources to be associated with the ... -
nox reduction of biodiesel operated diesel engine using different techniques: (egr, steam injection and emulsification)
(2018)the increase in world population has led to the growth in energy demand. the primary sources of this energy come from the combustion of conventional fuels, which are contributing to polluting the environment. biodiesel ... -
studies on water quality of aquaculture farms with an emphasis on flavobacterium psychrophilum and uv treatment
(2016)flavobacterium psychrophilum, the causative agent of coldwater disease, affects salmonid fish in aquaculture operations worldwide and causes skin lesions which if left untreated results in spinal deformities, spiral swimming ... -
improved anti-melanoma and anti-melanogenic effects of birch bark triterpenes delivered in ethosomes
(2018)north american birch species of the boreal forest contain significant amounts of pentacyclic triterpenes in their outer bark. betulin (be) and betulinic acid (ba), pentacyclic triterpenes readily extracted from outer birch ... -
people in discursive spaces : entry-level humanities eduction for non-traditional adult learners
(2018)in canada there are programs that offer non-traditional adult learners an entry-level university educational experience. these programs have various names, for example, humanities 101, university 101, discovery university ... -
a multiomic approach to paleogenetic investigation of ancient north american bison
(2018)twelve ancient bison bone samples from north-central north america were examined using genetic and proteomic sequencing to determine relationships to other bison populations. mitochondrial dna sequences suggest a genetic ... -
archaeobotanical and soil chemistry investigation of a woodland site on whitefish lake, northwestern ontario
(2017)whitefish lake is a large, shallow lake abundant in wild rice (zizania palustris) that lies near the transitional zone between the boreal forest and great lakes-st. lawrence forest regions of northwestern ontario. the ... -
an improved multi-variate empirical mode decomposition method towards system identification of structures
(2018)structural health monitoring (shm) plays a key role towards condition assessment of large-scale civil structures using modern sensing technology. once the rich vibration data is collected, important system information ... -
dispersion and flocculation affinity of anionically charged kraft lignin
(2018)softwood kraft lignin is a biodegradable, renewable, and environmentally friendly natural polymer. although kraft lignin is widely produced in canada, it is predominantly underutilized as fuel because it is only soluble ... -
algal mixotrophic metabolism for the production of lipids
(2018)the challenges associated with the use of conventional sources of crude oil increase the demand for alternative fuel sources. biofuels offer the chance of replacing the depleting fossil fuels. however, the food versus ... -
isolation and characterization of bioconversion microbes and aerobic conversion of crude glycerol to value-added bioproducts
(2018)renewable forms of energy are of significant interest in today’s economies. biofuel is a renewable fuel produced by biological means. biofuel is very useful because it does not have a finite supply, and it produces fewer ... -
extraction of phytochemicals betulin and betulinic acid from the chaga mushroom and their effect on mcf-7 cells
(2018)chaga mushroom (inonotus obliquus) grows on birch trees found mainly in temperate regions like canada, northern united states and siberia. it contains phytochemicals such as betulin and betulinic acid, which are a ... -
exploration of inflammasomes as targets for therapy of pseudomonas aeruginosa infection
(2018)pseudomonas aeruginosa is a common gram-negative opportunistic bacterial pathogen capable of infecting humans with compromised natural defenses and causing severe pulmonary disease. it is the major cause of severe chronic ... -
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 ...
