Net ecosystem exchange of carbon dioxide over agricultural fields near Lacombe, Alberta

Agriculture and Agri-Food Canada (AAFC) and Campbell Scientific Canada Corp. (CSC) have been operating an “eddy covariance” meteorological tower near Lacombe, Alberta that measures the flux of carbon dioxide (CO2) between agricultural fields and the atmosphere. This tower provides high frequency data that is used to assess plant growth and decomposition across large fields which is critical for understanding local crop viability and the role of Canadian agriculture in the global carbon cycle.

Alberta experience climbs to the top

Ankita was one of 200 top international students that undertook 3 month research projects over the summer at universities in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Québec, New Brunswick and Newfoundland and Labrador.

Restoring native grassland function in urban environment; implications for soil-plant relations

Fescue prairie has reduced in Western Canada, because of human activities including housing development and land clearing. Urban development can impact natural ecosystems by eliminating the majority of native species, thus changing the richness and composition of the species. Strategic restoration efforts may reduce the effects of urban expansion on native ecosystem by protecting natural habitat and re-establishing modified habitat.

Optimal Design of Interface Geometry of Pocelain-Fused-to-Metal (PFM) Dental Crown - an Experimental Study

In conventional crown structure, the crowns are bonded to the bottom layer with a cement layer. The major clinical failure mode is the subsurface radial crack at the interface between the crown and cement. This failure is caused largely by the tensile stress concentration/singularity in the dental ceramic at that interface. A sharp change in the structure geometry or/and mismatch in material properties at interfacial boundary is the source for such stress concentration/singularity.

Microchannel Simulations with the Lattice Boltzmann Method

The nanofluidics and microfluidics simulations and experiments are becoming more and more popular nowadays. Such devices work on microscale to imitate macroscale operations but on a cheaper and faster basis. The good examples are lab-on-chips which perform DNA tests much faster and much cheaper than their large anologues. Thus, the reliable and robust simulations of micro devices are in high demand. One of such examples is multiphase simulations of fluid flow inside the capillaries.
