The advent of blockchain technology has revolutionized the perception of modern payment systems. However, in such a system securely managing one’s wallet is a challenging issue. A typical user has access to a suitable wallet software and uses it to authenticate transactions. As wallets generate digital signatures, it requires an access to the private key of the user. The presence of a key in a system which often comes online increases its vulnerability - when a wallet is hacked then essentially the private key is lost and so is the money associated with it.
Alberta’s Oil and Gas (O&G) sector plays a critical role in Canada meeting its commitment to the Paris Climate Change Agreement. However, few studies published the actual operation data for extraction operations (schemes), especially fuel consumption data to accurately project greenhouse gas (GHG) emissions for development and expansion of O&G projects.
Internationally Educated Health Professionals (IEHPs), are those who completed their health professional degree (e.g., nursing, MD, etc.) from outside Canada. Many of the IEHPs, however, cannot integrate into their ideal career i.e., nurse, physician, etc. and remain underemployed in non-skilled jobs. The low rate of success in obtaining their respective career in Canada leaves no choice but to explore alternative career options. A lack of information and strategic support, lack of job counseling and coaching opportunities for IEHPs further obstruct their pursuit of alternative careers.
Burning fuels such as gasoline and diesel in our vehicles causes green house gas emissions and it is a major cause of global warming. If electric vehicles replace gasoline powered vehicles, the emission will be much lower. The peak power demand of an electric vehicle during acceleration is the key factor for its battery size. The large battery size causes less optimal use of energy and finally ends up with lower mileage in electric vehicles. These limitations could be solved by combination of battery system with supercapacitors.
With the growth in demand for electric vehicles and mobile devices powered by rechargeable lithium batteries, demand for lithium is expected to increase by over 200% in the next decade. Current lithium production comes primarily from Australia, South America and China. There are significant lithium reserves in the same Saskatchewan aquifers currently being exploited for their concomitant oil reserves.
Renewable sources of electricity continue to increase in market share across all jurisdictions. New wind and solar energy projects in Alberta will be the main drivers to reach the province’s 2030 target to have 30% of its electricity derived from renewable sources. Alongside these projects the power generation companies like TransAlta Corporation will need to look at energy storage solutions to help these intermittent sources of electricity provide reliable and consistent power to the consumer.
The ever-growing market of portable electronic devices (e.g., laptop computers, tablets, smartphones) has resulted in the penetration of AC adapters in households greater than ever. Accordingly, the portability of such devices entails substantial demands for light-weighted and compact devices. This necessitates the critical need for high power density and highly efficient adapters. In particular, consumers continuously expect to have a more compact adapter with higher efficiency. Besides, the current technology has reached mature stages.
An Indigenous community living near Alberta’s oil-sand mines is concerned that mining operations may be harming the rivers and lakes where they fish, hunt and trap. The research looks at finding the locations along the edges of rivers and lakes where there is evidence that mining operations may be affecting these waterbodies. The unique part of the research is that Indigenous knowledge, which is the wisdom owned by the community, and Western science are being combined in complementary and respectful ways to find the affected locations along the edges of rivers and lakes.
Microorganisms living in marine seafloor sediments are of scientific interest for many reasons including their role in cycling nutrients, their metabolic diversity, and the relatively few investigations of their existence due to their habitation of such an extreme and isolated environment. In addition, subsurface microbes can provide insight into their surrounding environment, including signalling the presence of hydrocarbon seeps.
What is left after late-life SAGD production is a large amount of valuable energy in the form of heat contained in the reservoirs. Instead of leaving behind the stored energy in a hot reservoir after many years of SAGD operation, considering energy recovery from post-SAGD reservoirs leads to lower carbon emissions by saving energy already injected in the reservoir rather than leaving it to avoid burning more natural gas; saving money for SAGD operators and helping to make operations more sustainable.
