Industrial development, including geophysical exploration and mining, has increased use of explosives in and near fish habitat. To protect fish and their incubating eggs, Canadian blasting guidelines contain maximum allowable limits for overpressure and peak particle velocity (PPV). Although many...
Heterogeneity of surfaces is often included in mathematical treatments of colloid transport and deposition as an afterthought, if at all. Most previous models of colloid transport and deposition have employed idealizations and simplifications such as assuming smooth collector surfaces with...
Effects of long-term nitrogen and sulfur deposition on soil microbial communities and soil properties in the Athabasca oil sands region in northern Alberta, CanadaDownload
Intensified oil sands activities have resulted in elevated levels of nitrogen (N) and sulfur (S) deposition in the mixedwood boreal forest in the Athabasca oil sands region (AOSR) of northern Alberta, Canada. The deposition of N and S can affect the surrounding ecosystem and it is important to...
Studying Structure-Nanoaggregation Relations of Polyaromatic Molecules in the Bulk Oil Phase and at the Oil-Water Interface Using Molecular Dynamics SimulationDownload
The detection, identification and characterization of early stage molecular association of polyaromatic molecules into nanoaggregates, where these nanoaggregates represent the first level of molecular clusters or building blocks are critical in areas such as design and fabrication of advanced 3-D...
Most current models for the deposition of aerosol particles in the human lung are based on a Lagrangian reference frame, which is ill-suited for modeling transient eects. Deposition models based on an Eulerian reference frame are much better at capturing instantaneous time-dependent eects, though...
Colloidal-collector interactions are of fundamental importance in separation and filtration technologies. Here, the effect of collector grains on the behavior of colloidal particles was studied in two different experimental systems, i.e., column studies with stationary collectors and batch mixing...
Study of Enhanced Deposition due to Magnetic Field Alignment of Ellipsoid Particles Using Direct Numerical SimulationsDownload
A recent in vitro study demonstrated a non invasive method to enhance local deposition in a small airway by controlling the angular position of magnetic high aspect ratio particles. This technique could mitigate the challenge of providing sufficient therapeutic effects when using aerosolized...
Glancing angle deposition (GLAD) is a physical vapour deposition (PVD) technique capable of fabricating highly porous thin films with controllable film morphology on the 10 nm length scale. The GLAD process is flexible and may be used on virtually any PVD-compatible material. This makes GLAD a...
Structural and Biochemical Changes in Loblolly Pine (Pinus taeda L.) Seeds During Germination and Early-Seedling Growth. I. Storage Protein ReservesDownload
Abstract: Quantitative and qualitative changes in the storage proteins of loblolly pine (Pinus taeda L.) seeds were followed during germination and early-seedling growth and were correlated with light-microscopic observations. In both the megagametophyte and the embryo, the cells of tissues from...
With climate change rapidly affecting northern forests and wetlands, mercury reserves once protected in cold, wet soils are being exposed to burning, likely triggering large releases of mercury to the atmosphere. We quantify organic soil mercury stocks and burn areas across western, boreal Canada...
