Occupying the large tailings ponds is the most significant environmental issue for oil sand conventional extraction process. Making Green Ceramic/building materials is the most promising method to reduce the size of tailings ponds. This not only leads to consumption of tailings but also results in valuable products for the construction industries.
The shortage and quality of food to feed the existing and growing population is an issue of global concern. There is also serious problem with the fungal and bacterial pathogens which result in losses of billions of dollars of annual loss of agricultural products. This project is an attempt to mitigate this with the use of X-ray treatment of seeds and organic products in stead of gamma rays or electron beams of a few MeV energies.
Driven by climate change induced water scarcity, further enhanced by rapid urbanization and population growth, potable water reuse initiatives are gaining interest. Potable reuse involves the indirect or direct use of highly treated municipal wastewater as a municipal drinking water source. Historically, the most commonly installed potable reuse train consisted of microfiltration, reverse osmosis (RO), and ultraviolet (UV) as treatment stages.
Canada Pump & Power (CPP) is an Alberta specialized industrial marine company. CPP has a novel proprietary dredge propulsion method based on a set of winch-driven cables: the patented Autonomous Mighty Dredge. Control strategies to date have delivered adequate performance in some operating conditions; the goal is to have the dredge capable of performing to a slurry rate specification under automatic control in a wide range of operating conditions (variable deposits, density, obstacles).
A two-year study on brazing technologies used for sintered tungsten carbide tiles is proposed to address the following technical objectives: 1) brazing metallurgy for sintered tungsten carbide and substrate high strength steel, 2) adherence mechanisms between different braze compositions and carbide tiles, 3) brazing parameters for optimized brazed joint performance, and 4) the mechanical stresses developed through the brazing process.
Next-generation integrated circuits require the innovation of new interconnect materials in order to maintain the performance improvements of Mooreâs Law scaling. Cobalt (Co) and ruthenium (Ru) are two specific metals that are garnering strong interest for use in the filling of interconnects because of their better electrical performance and reliability at the extremely scaled dimensions required by sub-10 nm technology nodes.
Thus far Steam-Assisted Gravity Drainage (SAGD) has been the sole commercially viable in-situ recovery method to extract Canadian oil sands that are too deep for mining. It involves high pressure steam injection and bitumen production using horizontal well pairs located near the base of oil sands formations. While it has enabled conversion of significant resources to reserves (about 170 billion barrels), SAGD has many economic and environmental limitations. The public and government want to see the negative aspects of SAGD reduced significantly.
The main goal of the proposed work is to develop an ultra-thin and selective GO membrane capable of separating water vapor or steam from air. For this purpose, a suitable membrane supports required to hold the GO sheets. Therefore, the GO sheets will be deposited on various membrane supports and their performance in terms of selectivity, permeability, and mechanical strength will be evaluated. Then, the effect of GO layer number on the selectivity and permeation rate will be investigated.
VETWATER (Sainte-Brigide-d'Iberville, QC) produces pet equilibrated water under the commercial name of "VETWATER urinary solution for cats" (VC), which helps preventing urinary crystals and stones (urolithiasis) by equilibrating pH strictly in the 6.2-6.4 range. Besides urolithiasis, feline lower urinary tract diseases (FLUTDs) affect the urinary bladder and urethra of cats without any obvious underlying cause- so called "feline idiopathic cystitis" (FIC).
Devonian reservoirs have contributed significantly to the development of the petroleum industry in Alberta. This is mainly due to their favourable characteristics of high permeability enhanced by dolomitization in these often reefal structures. Although many have had good recoveries, much oil remains to be recovered. Many of the same characteristics that led to good production performance during the past decades are expected to contribute to good production potential if CO2-based enhanced-oil recovery (CO2-EOR) methods are employed.
