Skin-penetrating bone-anchored implants are used in a variety of applications to provide tremendous functional benefits to patients. Globally, the dental implant industry has been valued at 5.08 billion USD where implants are used for replacing single teeth, for larger prostheses, and for full dental arches. The success of these implants relies on a structural integration between the implant and the living bone. Evaluation of the integrity of the bone-implant interface is important to prescribe loading, to identify the risk of failure, and to monitor the long-term health of the implant.
The current workflow for COVID-19 testing is overwhelmed for many reasons including the need for time-consuming sample preparation, the limited availability of test reagent, and the length of time it takes to complete the test process (approximately 3 hours). As the test-and-trace approach is critical to containing the spread of this virus, rapid diagnostics are crucial. To improve the testing timeline, diagnostic labs need to process samples quickly, which requires the use of automated tests. The use of magnetic bead technology is highly amenable to automation.
This design research project explores existing and ongoing perspectives on (post) pandemic conceptions in built environment settings in Alberta, from an architectural design perspective. The results will add to the scholarly research on sustainable design of “public spaces” to support (post) COVID-19 period health concerns and recommendations, thereby contributing to the development of healthier design and more equitable, sustainable communities in Alberta.
This project is to research and develop a portable hot-cold sensation diagnostic device which will be used to test and record the degree of hot and cold sensation on patient’s limbs. Traditional method uses test tubes filled with warm water or cracked ice and water for testing. Temperature less than 5oC and greater than 45oC elicit painful responses in addition to temperature should be avoided. The proposed device not only integrates the key sensory testing tool, but through its electrical components, it provides method to conduct reproducible tests.
The goal of the Dissolvable Glass Technology research project is to develop new glass technologies and products to reduce the cost and environmental impact in the utility, forestry, and oil and gas sectors. It has been said that we are ‘entering the age of glass’, and we aim to explore the numerous and varied possibilities where dissolvable glasses can be utilized. However, to achieve these glass technologies, fundamental glass research must be performed in three key areas: mechanical properties, thermal behaviour and dissolution behaviour.
Dental personnel are high risk professions in contracting and disseminating COVID-19 due to their transmits through respiratory droplets, dental personnel are at high risk of being exposed to the virus if an asymptomatic
patient comes to their clinic. However, limited studies have been performed on the characterization of aerosols generated during dental procedures, how far these aerosols may travel in the clinic, and if they accumulate during the day.
Carbon dioxide is produced from the combustion of fossil fuels and as a by-product of many chemical processes. The increasing concentration of CO2 in the atmosphere has now been decisively linked to global climate change. The use CO2 as a carbon-building block has attracted much attention due to its low cost, ease availability, and its potential to substitute fossil fuel-based feedstocks, in addition to the clear positive environmental effect of removing it from the atmosphere.
Over the air (OTA) test is the standard procedure for wireless devices to verify the transceiver and antennas performance together in specified conditions. Any wireless device such as tablets, phones and laptop must go under OTA testing. Furthermore, regulatory organizations require OTA testing before the wireless device being certified.
Due to the time-consuming procedure of OTA testing, currently manufacturers and vendors limit themselves to a small sample of devices for testing.
Hydroponics is a farming method that does not require soil, but rather utilizes a porous medium to hold plants so that waste of irrigation solution is minimized. This type of farming is considered more expensive than traditional open-field agriculture. However, it has been found to function well in enclosed spaces with a controlled environment, especially in cold climates where open-field agriculture is challenging.
There is a growing demand when it comes to the repairing of the coke drum since most of the current in-use coke drums has been in service for decades. This study will develop a new methodology to assess the microstructure evolution and thermal mechanical properties of service-exposed coke drums. The focus of experiments of this project involves high temperature fatigue test to evaluate the fatigue life of the material. Through the studying, the evolution of microstructure evolution will be better identified and understood, providing the foundation of the analysis in the future.
