Modelling soil temperature on the boreal plain with an emphasis on the rapid cooling period
(2009-10-15)
To accurately model soil temperatures on the Boreal Plain, factors that influence fine-grained
soils during the rapid cooling period must first be identified. The effects of air temperature, soil
moisture and snow depth ...
Synthesis, characterization and photocatalytic application of TiO2 nanosized particles / by Dongliang Liao.
(2007, c200)
In this thesis, effects of surfactant composition and concentration on shape, size, zeta potential, and photocatalytic activity of TiO2 nanosized particles are reported. Spherical, cubic, rod, ellipse and leaf-like shaped ...
Characterization and utilization of fly ash derived from the co-combustion of biomass and coal as a mineral admixture for ordinary Portland cement
(2009)
Co-firing coal with renewable/waste biomass for power generation can mitigate the atmospheric discharge of pollutants (e.g., SO2) and green-house gases. Wide-spread application of this technology is impeded, however, by ...
Fish biomonitoring in an industrial environment : the Toxicity Early Warning System (TEWS)
(2009)
Industrial, agricultural and municipal effluent discharge into receiving waters continues to be a significant environmental problem. Currently, industrial effluent quality is assessed using chemical assays or by evaluating ...
Evaluation of GaN and InGaN semiconductors as potentiometric anion selective electrodes
(2006)
Ion selective electrodes (ISEs) are chemical sensors primarily used for in situ analysis and monitoring of air, water, and land. Despite their easy fabrication, low cost, and simple usage, ISEs still suffer from the ...
Effect of water salinity on the hydro-mechanical behaviour of light backfill material
(2007)
A series of one-dimensional compression tests was conducted to examine and compare the hydro-mechanical behaviour of light backfill (LBF) material, composed of 50% bentonite and 50% sand, in the presence of distilled water ...
Submerged anaerobic membrane bioreactors for Kraft evaporator condensate treatment : feasibility and membrane fouling studies
(2008)
In this study, the primary goal was to develop better treatment technologies for energy recovery from Kraft evaporator condensate (EC) using thermophilic and mesophilic submerged anaerobic membrane bioreactors (SAnMBRs). ...
Production of bio-crude from forestry waste by hydro-liquefaction in sub-/super-critical methanol and upgrading of bio-crude by hydro-treating
(2009)
Bio-energy is renewable and clean (with trace amount of sulfur and neutral in terms of CO2 emission), and abundant in resource, thus it could be a securable and sustainable energy for future. Due to the declining reserve ...
Modeling the transport of Escherichia coli through the subsurface environment
(2009)
Subsurface microbial transport is an important concern in many engineering projects. Expanding the knowledge of this process is important for the risk assessment of sites capable of releasing pathogenic bacterial species ...
