Wollastonite(CaSiO3) and diopside(CaMgSi2O6) are silicate minerals occurring in the mining operation near Kingston. Quantity of each mineral in the deposit vary from 30 to 40%. An efficient separation of wollastonite from diopside represents a challenge in processing this ore. Efficiency of flotation separation at high levels diopside is not consistent since both silicates respond the […]

An oil well drillstring is a slender slru(.;ture whidl vibrales in 3 major coupleu moues. Unwnlrolkd vibration of the drillstring interferes with the drilling procedure. Tool and bit failure, improper borehole quality and lower penetration rates are examples of the side effects of unwanted vibration of the drillstring. Prior research by others has attempted to […]

Northern Canada faces environmental changes from growing resource extraction and global warming, which make an understanding of baseline conditions critical. In the Dawson Range, Yukon, naturally elevated concentrations of uranium have recently been discovered in groundwater at levels that exceed federal water-quality guidelines. This region is also the focus of advanced mineral exploration and falls […]

Phytoremediation is a promising in-situ technology that uses plants and its associated microorganisms (particularly bacteria and fungi) to clean up contaminated soils. The efficacy of these processes however, requires an in-depth knowledge on the diversity of microbial communities closely interacting with plant roots. Several studies have demonstrated that plants growing in contaminated soils select for […]

Boiler wall tubes are important components in boilers for safe and efficient operation. After service exposure, boiler wall tubes often require replacement or repair, in which new sections of boiler tubes are welded onto the old boiler walls. Following the repair welding, the code requires the boiler be hydrostatic tested before putting the boiler back […]

The drilling success rate is the most important goal for any oil/gas company. For a start-up company, any failure in drilling will be a disaster. To this end, the Petro-Lin Energy Corp. wishes that through the combination of mature hydrocarbon prediction techniques and new research results such as machine learning, the success rate of hydrocarbon […]

Offshore petroleum exploration requires a multitude of techniques to identify a petroleum system in an offshore area. Novel microbiology technologies which focus on the distribution of marine microbes (microbial biogeography) have been proposed as complementary tools to conventional techniques for oil and gas exploration. Hydrocarbon seepage from subsurface petroleum reservoirs is hypothesized to explain the […]

The aim of this proposed research is the development of an efficient technology to convert carbon dioxide (CO2) via Dry Reforming of Methane (DRM) to produce value-added products. DRM, one the promising CO2 utilization technologies, has gained much attention as not only it reduces greenhouse gases (GHG), but also converts them to a valuable product, […]

Recent pipeline projects in Canada and the US have attracted lots of attention due to their importance for our future economy and environment. In the proposed project University of Alberta and Shawcor propose to work together towards developing E-smart pipelines and creating defect free system. We will utilize the vast amount of emerging and cutting-edge […]

Immunomagnetic cell isolation particles are widely used to separate cells from complex, biological environments, such as blood, urine, or bone marrow. Cell isolation particles are typically decorated with specialized antibodies to bind to targeted cell surfaces via specific antibody–antigen interactions. These interactions can be disturbed by the presence of serum proteins, which are common constituents […]

The evaluation of mining projects depends on modern computational techniques. There is a demand for increasingly sophisticated techniques, due to environmental considerations and the drive toward increasingly complex ores. Without these techniques, projects may be wrongfully held back or abandoned, leading to severe socioeconomic consequences in the surrounding communities. Conversely, mining projects may be wrongfully […]
