Continued population assessment of Atlantic sturgeon (Acipenser oxyrhynchus oxyrhynchus) in the Restigouche River estuary, New Brunswick

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?”.

Validating the Positive Workplace Framework to strengthen mental fitness, resiliency, and positive leadership practices

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.

Testing Bearing Capacity of Precast Hollow Core Slabs at Load Bearing Wall – Slab Joint

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.

Sub-habitat use by fish in restoring and established salt marshes in mega- and microtidal regimes

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.

Extending Assessments of Cognitive Decline into Virtual Reality

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.

Design of asphalt mixes using pyrolysis products

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.

Internet-of-things (IoT)-based Data Collection and Analytics for Onsite Scaffolding Project Management

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.

Use of UHPC as a building material in Northern climates

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.

Biotic communities in restoring salt marshes

Salt marshes are important coastal ecosystems that provide many services. Due to their high soil fertility, they have a long history of being converted to farmland. There is now growing interest in restoring salt marshes to protect against coastal erosion, mitigate sea level rise, and provide increased habitat for fish, birds, etc. Ducks Unlimited Canada and partners initiated 5 salt marsh restoration projects between 2010–2020, in the Bay of Fundy and southern Gulf of St.

Water Quality, Waste-Solids Dewatering, and Seawater Filtration at a Zero-Exchange Recirculating Aquaculture Farm

Due to the depletion of natural fish stocks, the aquaculture industry must build larger land-based farms to meet the growing demand for seafood. Currently, the availability of clean, inland fresh water is limiting the size of farms so the only way the industry can expand these farms is by reducing the water exchange. Cooke Aquaculture Inc. is currently constructing a state of the art zero-exchange system to produce salmon smolts. This research project aims to improve the understanding of zero-exchange systems by exploring three areas which require further research.
