The aim of The Ontario HIV Treatment Network (OHTN) is to help combat the spread of HIV by supporting, conducting, and sharing the best research possible. This project will involve a novel analysis incorporating focus groups with front-line service providers and key informants to help determine the factors that most influence the perception of HIV risk.
Use of aluminum alloys in the automotive industry comes with huge manufacturing challenges such as instability of spot welding processes. To overcome this challenge, frequent selective quality tests are performed in industry usually by destructive means, which are labour intensive and costly due to its nature. Non-destructive testing (NDT) of aluminum spot welds can decrease these costs. This proposed spot welding NDT method will incorporate an ultrasonic probe in the welding electrode, which is fully automated and each spot weld tested at the moment of manufacture.
Capturing the real human motions on the assembly plant floor is the key point for developing accurate virtual simulations. The real human motions of specific workstation operations at Ford Oakville Assembly Plant by using wearable inertial sensors will be collected. After data collection, virtual simulations will be performed for all the recorded operation tasks. Based on simulations, physicians can observe and conduct ergonomic assessment of each of operation tasks on the plant floor.
Al6022 alloy has excellent physical and mechanical properties suitable for a number of applications. In particular, its high strength/weight ratio makes it an ideal metal for automotive applications, where weight reduction is of significant concern. Unfortunately, this alloy, as many
other Al-based alloys are susceptible to denting. At present, the repair possibilities for damaged Al6022 automotive panels are very limited, while their exposure to denting is unavoidable.
This project focuses on the research and development of a novel two-stage anaerobic digestion (AD) process to create an array of renewable products such as transportation fuels, chemicals, and plastics from sustainable biomass sources i.e. lignocellulosic crops, and to use wastes such as agricultural residues or municipal green bin collections or animal manures. The novel process will expand the application of the AD process beyond its current primary use for solids and organic wastes treatment to a first-of-a-kind venue.
Intimate partner violence (IPV) and sexual violence (SV) are unfortunately common occurrences in women’s lives. Women with a disability are at higher risk of these experiences. Disabilities such as depression have been researched and we now turn our attention to a condition that has not been researched: acne.
Dental hygienists (DH) are exposed to many potentially injurious physical demands, such as prolonged exposure to awkward neck, trunk, and shoulder postures. The prevalence of musculoskeletal disorders in this group is alarmingly high (62-93%). DH would benefit from ergonomics-specific workplace safety education, but it is unknown what sort of instruction, if any, is currently offered within the DH curriculum or for continuing education credit. Evaluation of existing educational opportunities will be conducted using a web-based survey of DH across Ontario.
Circadian rhythms are processes which allows animals to regulate their physiology based on time of day. These rhythms are controlled by the circadian clock, a group of transcription factors that form a feedback loop. Over 40% of the genome is transcribed rhythmically, implicating the clock in many physiological processes. The cell cycle is another process which takes ~24h to complete in mammals. This is due to several checkpoints which are present to prevent the cell from precocious progression leading to DNA damage.
Additive manufacturing (AM) is a process family which is widely used for deposition of thin protective layers of novel alloy materials on components operating in severe conditions, and also for fabrication and repair of complex 3D parts. The scope of this research is to establish a process planning framework for metal based bead deposition processes that considers the various machine, materials, and process parameters.
The United States Coast Guard (USCG) recently introduced stringent regulations for the treatment of ballast water. Ultra-violet (UV) light is a useful technology in a ballast water treatment system (BWTS), for inactivating species which could be invasive and harmful to humans and the environment. UV damages DNA and prevents replication, but the vital stain methods mandated in the USCG protocol do not detect UV damage. Alternative culture-based measures of cellular replication capacity are yet to be approved, time consuming, and have limitations (some species mayn't grow).
