Recent advances in the field of neural prosthetics have demonstrated the thought control of a computer cursor. This capability relies primarily on electrode array surgically implanted into the brain as an acquisition source of neural activity. Various technologies have been developed for signal extraction; however most suffer from either fragile electrode(More)
Oil sands mining in the Athabasca oil sands region disturbs large tracts of peatlands as the vegetation-soil layer must be removed. Processing oil sands produces large volumes of wet material containing oil sand process-affected water (OSPW) that has elevated concentrations of sodium (Na) and naphthenic acids (NAs). Attempts to reclaim mined landscapes to(More)
The organic matter accumulation potential of a restored bog was estimated over 2 years as a balance between losses to decomposition and inputs through above-ground net primary productivity (AGNPP) in five micro-habitats of increasing complexity (relating to the moss carpet thickness and the number of vegetation functional groups). Decomposition and(More)
Peatlands support vital ecosystem services such as water regulation, specific habitat provisions and carbon storage. In Canada, anthropogenic disturbance from energy exploration has undermined the capacity of peatlands to support these vital ecosystem services, and thus presents the need for their reclamation to a functional ecosystem. As attempts are now(More)
