Mactaquac Generating Station, the largest hydroelectric power plant in the Maritime provinces, is located near the capital city of Fredericton, on the Saint John River. In the mid-1970s, concrete structures at Mactaquac began to show signs of distress due to Alkali-silica reaction (ASR), resulting in cracks and leakage. The goal of this research project is to develop a continuous ambient vibration monitoring and damage detection system for the intake structure of the Mactaquac dam.
Injuries and bad habits can derail an athlete’s career and quality of life. Pascal McCarthy learned this first-hand when his professional volleyball career was cut short due to recurring injuries. That’s when he saw the gaps in the medical system when it comes to treating sports injuries, including concussions, and decided to do something about it.
There are Atlantic sturgeon in the Restigouche River estuary. This species is millions of years old and it is still found in our waters today. Fishers have reported their sightings every year in the last decade. Unfortunately, this species is now considered to be a species at risk of extinction. Because their numbers are so low, we do not see them that often in the area and therefore do not know a lot about them. Our project aims to answer community members’ questions about these fish in the area, such as “what can we do to help them?”.
The COVID-19 pandemic has highlighted the need to address workplace wellness. The Positive Workplace Framework (PWF) is used in many workplace settings to improve well-being, engagement, and productivity. This study will address the French version of the PWF and its two questionnaires, the Mental Fitness and Resiliency Inventory (MFRI) and the Positive Leadership Inventory (PLI). The PWF’s theoretical foundations validated, the psychometric properties of both questionnaires will be described, and the important role leadership competencies play in a workplace will be demonstrated.
Precast concrete is used in many types of structures including those serving commercial, multi-unit residential, and industrial uses. Hollow core prestressed slabs (or planks) are one type of precast concrete that is used primarily for flooring systems. These planks have advantages of being able to span long distances while being relatively thin and light when compared with cast in place concrete solutions while being economically advantageous to manufactures and builders due to their ease of production.
Salt marshes are coastal wetlands that provide many ecosystem services. Many fish species are known to use salt marshes as habitat at some point throughout their lives including those that hold commercial and recreational value. Depending on their location, salt marshes may experience varying degrees of tidal flooding, not only making more areas of the marsh accessible to fish but resulting in excess particulate and dissolved organic matter being drawn out with the ebbing tide.
Early detection of dementia among seniors has been an ongoing struggle, leading to underdiagnosis, late diagnosis, and delayed intervention. Using virtual reality powered hardware and proprietary motion tracking software provided by Innerva Virtual Inc., this project intends to create a dual-task assessment to measure mild cognitive impairment (MCI) among older adults, a leading symptom of dementia. We will measure the effectiveness of using standardized virtual environments to facilitate gait assessments and measure MCI.
This project will support a Master’s UNB student to investigate the impact of including pyrolysis products (bio-oil and biochar) in asphalt mixtures by designing asphalt mixes that meet the requirements set for pavement applications. The use of carbon-rich bio-oil and biochar; could positively impact the properties and rate of oxidation of asphalt materials. Also, the use of biomaterials contributes to the sequestration of carbon, preventing the creation and emission of carbon dioxide. Ensyn will provide the material (i.e.
Scaffolding, as a type of temporary structure on construction sites, provides access for trades to certain areas for performing construction activities. Depending on project sizes, the budget for scaffolding can account for a substantial amount of the total direct work budget. Failure to the management of scaffolding activities can result in cost overrun and schedule delays in the projects. Meanwhile, scaffolding management is challenging by its nature, e.g., ad-hoc trivial daily activities with various material components consumed at different locations.
In this project different UHPC mixes will be proposed and tested for mechanical and physical material properties when subjected to extreme cold temperatures. The mixes which meet the required properties and are most economical will be used for further structural wall panel testing and will be proposed to the company. The proposed concrete mix will be used to build insulated sandwich wall panel specimens and structural strength test will be conducted on them.
