We construct a continuum model for biological aggregations in which individuals experience long-range social attraction and short range dispersal. For the case of one spatial dimension, we study the steady states analytically and numerically. There exist strongly nonlinear states with compact...

In many applications, it is desired to separate unwanted fine particulates from a liquid by gravity settling. An efficient separation, however, will be feasible only if a combination of aggregation and sedimentation occurs. To understand the kinetics of such a process, a mathematical model that...

At different stages during the extraction of bitumen from the Athabasca oil sands, the removal of unwanted fine solids whether suspended in aqueous or non-aqueous liquids continues to present serious challenges to the oil sands industry. These fine solids are unique in that their colloidal...

Technical report TR06-24. Wireless sensor networks have received much attention recently. Given their autonomy, flexibility and large range of functionality, they can be used as an effective and discrete means for monitoring data in many domains. Typically the network autonomy implies a limited...

This thesis explored the properties of asphaltene nano-aggregates in crude oil and toluene based solutions and fouling at process furnace temperatures, and the links between these two phenomena. The link between stability of asphaltenes at ambient conditions and fouling at the conditions of a...

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...

Hymenolepis diminuta (Cestoda) induces changes in expression of select genes of Tribolium confusum (Coleoptera)
Download2009
Belosevic, M., Shostak, A. W., Hitchen, S. J.
The flour beetle Tribolium confusum is a common experimental intermediate host for the tapeworm Hymenolepis diminuta, but while many aspects of their host-parasite interactions have been determined to have genetic basis, the genes involved have not been identified. In this paper, we report on the...

Identifying seasonal Lake Sturgeon (Acipenser fulvescens) movement patterns and habitat selection in the South Saskatchewan River Basin
DownloadFall 2016
Lake Sturgeon (Acipenser fulvescens Rafinesque 1817) have experienced population declines throughout their range. In Alberta, low density age-class distributions, irregular recruitment, critically low spawning potential ratios and other factors led to a 2007 designation of “Threatened” for this...

To monitor/evaluate our changing environment a tool being deployed is sensor networks. Autonomous nodes, often referred to as motes, that are deployed in a terrestrial sensor networks typically consist of four functional blocks; 1. a sensor section, with one or more sensors (i.e. seismic,...

Mechanisms of Aggregation and Separation of Water and Solids from Bitumen Froth using Cluster Size Distribution
DownloadFall 2016
The large-scale corrosion and equipment damage caused by water and solids respectively in bitumen froth necessitate their removal using various methods. This study is aimed at understanding how water and solids aggregate (water-water, water-solid and solid-solid) in bitumen froth and what the...
