An in-depth review of the literature related to deposition of gases and particulates by dry deposition and precipitation scavenging is reported. Recommendations are made on the hypotheses, algorithms or models considered to be most suitable for incorporation into a pollutant transport and...
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...
Planktonic and Epipelic Algal Communities and their Relationship to Physical and Chemical Variables in Alpine Ponds in Banff National Park, CanadaDownload
We surveyed 14 ponds in 1999 and 28 ponds in 2000 to better understand the basic limnology of alpine ponds and to predict how the planktonic and epipelic (sediment-living) algal communities may respond to nutrient deposition and climate change. Based on nitrogen to phosphorus ratios, nitrogen...
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...
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...
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...
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...
Development of Empirical Models to Predict Deposition of Aerosols in the Extrathoracic Airways of ChildrenDownload
The experimental studies described in this thesis were performed with the goal of measuring deposition of aerosols, inhaled either nasally or orally, in the extrathoracic airways of children in different age groups. We pursued in vitro methods and characterized the deposition of aerosols in the...
