Alternum optimization and validation to support primary cell growth and advanced 3D model

For a hundred years, fetal bovine serum (FBS) is used for cell culture. Cell culture is a critical tool for understanding life, through research, as well as manufacturing biologics, such as vaccine and lab grown meat. It is also used to reproduce tissue which can be used in human graft. FBS is the fertilizer for cells to grow better in an artificial environment. Though it has been unsurpassed, collecting FBS means sacrificing fetuses and pregnant cows. Altema develops new media supplements to replace FBS.
Primary cells are challenging to grow artificially. Optimizing and validating Altema’s products to work as well for primary cells is a major step for Atterna and for replacing FBS in all applications.

Optimisation de la soudure FSW à double épaulement des alliages d’aluminium pour une épaisseur de 12mm : Étude expérimentale et caractérisation des propriétés mécaniques

La soudure par friction-malaxage à double épaulement (FSW) est une technique solide en plein essor avec des avantages tels que l’absence de fusion du matériau et des propriétés mécaniques améliorées des joints.
Cependant, la norme actuelle ne fournit pas de données sur les propriétés mécaniques du FSW, ce qui limite son utilisation. Un projet propose donc de caractériser le FSW pour l’inclure dans la norme. Des études antérieures ont montré le succès de cette technique sur des épaisseurs de 8 mm. Cette étude vise à étendre les recherches sur des pièces de 12 mm en utilisant la soudure FSW à double épaule, offrant une meilleure répartition de la chaleur et une plus grande flexibilité.

Élucider l’impact des mutations de la séquence codante sur la traduction des protéines

La synthèse d’une protéine dans la cellule comporte plusieurs étapes, dont les principales sont la transcription du gène correspondant en un ARN messager et la traduction de celui-ci par le ribosome. On pourrait penser que le nombre de copies ainsi produites est indépendant de la séquence en acides aminés de la protéine – qui dicte ses propriétés –, mais ce n’est pas le cas. Puisque le ribosome décode séquentiellement l’ARN messager du début à la fin, des changements dans cette séquence peuvent ralentir ou accélérer sa progression. Une substitution d’acide aminé modifiant la protéine pourrait ainsi simultanément affecter son abondance, ce qui pourrait amplifier ou atténuer son impact fonctionnel. Vu ces interactions potentielles, il est hautement pertinent d’élucider comment les mutations dans la séquence codante d’une protéine affectent sa traduction. À cette fin, nous allons générer le totalité des substitutions simples possibles dans un gène de la levure et mesurer l’effet traductionnel de chacune d’elles. Ces travaux permettront d’améliorer notre compréhension du fonctionnement et de l’évolution des protéines – dont plusieurs sont d’intérêt médical, par exemple les cibles de molécules antibiotiques ou antifongiques.

Damage distribution along pipe subjected to rate-dependent ground movements with significant axial components

Buried pipeline systems form a key part of effective and safe infrastructures for the transportation of natural resources such as natural gas and liquid. However, they may be constructed in areas prone to landslides where ground movement may exert excessive strains on the pipe sections causing rupture. This project develops and presents a methodology for estimating strains in a pipe under axial loading induced by ground movement. The procedure calibrated and validated with pipe movement survey data and advanced computer modelling is based on a simplified analytical approach that can be readily implemented in practical design and analysis. A series of design charts are generated for performance evaluation of buried pipeline systems constructed in active slopes. They can be used to assess the frequency of necessary remediation such as in-situ stress relief procedure to protect the environment and maintain pipeline integrity and operation.

Learning from Lake Sturgeon (ki kiskinohamâkonânawan namewak): Weaving Indigenous and Western knowledge to assess cumulative effects in the Moose River watershed

Lake Sturgeon, known as Namew (nam-ay-o) in Moose Cree, are an important part of the Moose Cree First Nation’s culture and are a subsistence food source for the community. Namew are considered a species of special concern within the Moose River watershed, but are classified as an endangered species globally. As a long-lived species that can grow up to two metres long, Namew require clean, deep, fast-flowing, and large unfragmented lakes and rivers to live and reproduce. Contamination from industries like mining and forestry, as well as habitat fragmentation and changes in water levels due to hydroelectric dams and climate change, have contributed to Namew population declines around the world. The Moose River Watershed is under pressure from multiple stressors (e.g., new mines, forestry plans, hydroelectric facilities, and climate change) and Moose Cree Community Elders and Community Members are concerned about the health of all fish that they rely on, including Namew. While the Moose River Namew population is considered to be one of the healthiest in the world, little work has been conducted to determine the health of Namew and their habitat in this region.

Further development of sulphite-based dissolving pulp production

The requested Mitacs-Accelerate Internship application will support Dr. Yishan Liu (as an intern) and Dr. Yonghao Ni (as supervisor) of the University of New Brunswick and Neucel Specialty Cellulose. The overall objectives of the project are: 1) to improve the quality of dissolving pulps; 2) to decrease the manufacturing costs by using low-cost wood material. The improvements in pulp quality will be achieved based on enzymatic/ mechanical treatments that can be readily implemented at the existing mill configurations. The Canadian dissolving pulp production capacity has been expanded significantly in recent years. The results from the project will be beneficial to this growing sector, in particular, the industrial partner, Neucel Specialty Cellulose, by producing dissolving pulps with superior properties, hence, enhancing the value and competitiveness of their dissolving pulp products in the international market. Therefore, the proposed program is of direct relevance to Canada. Dr. Liu will be trained from the proposed program, and he will gain pertinent knowledge related to enzymatic/ mechanical/ chemical treatments, and dissolving pulp manufacturing processes and its quality control/ improvement. Upon completion, he will be prepared for employment in the pulp and paper industry

Long-term impact of sustainable cementing materials on the corrosion durability of reinforced structures

Production of ordinary Portland cement (OPC) contributes to 8% global CO2 emission. There is now increased effort to find alternative materials that are sustainable, readily available, and cheap. Several supplementary cementitious materials (SCM) from natural resources and waste product have been used to partially replace OPC and have shown beneficial effect. New efforts by Carbon Upcycling Technologies (CUT) towards a “net-zero world” has resulted in a carbon sequestering process to produce enhanced (i.e. treated) SCM (E-SCM). This effort also comes at a time where some Canadian Highway Bridge Code required service life has recently increased to ~100 years, despite increased structure exposure to harsh de-icing salt environment. Consequently, sustainability and durability of concrete structures are being sought by transportation authorities. This project will determine the long-term impact of E-SCMs on the durability of reinforced concrete structures which stands to aid commercialization and promote its increasing use for concreting, and therefore, place Canada in global leading space in low-carbon technologies.

Système de guidage autonome maritime afin de réduire l’impact du transport maritime sur les écosystèmes

Les technologies liées aux systèmes d’aide aux prises des décisions dans des navires intelligents ont atteint un niveau de maturité élevé dans les dernières années. Pendant ce temps, les navires autonomes et sans pilote ont aussi été largement étudiés en parallèle aux véhicules autonomes, comme les chargeuses autonomes dans les mines. Bien que la technologie de commande soit similaire, les difficultés rencontrées sont différentes dans la captation de l’environnement, la gestion des proximités avec les cétacés, la génération des chemins optimaux et des trajectoires, la localisation, la reconnaissance des entités autonomes par télécommunication ainsi que la logistique. De nombreuses technologies ont été développées concernant les stratégies de génération des trajectoires et d’évitement des obstacles, mais le défi demeure de taille lorsqu’il est question de conserver une distance minimale avec les haut-fond, les mammifères marins, en particulier les cétacés, tout en considérant les courants de marée, les conditions météorologiques (vent) ainsi que tout autre obstacle en mouvement. Ce projet propose une solution d’ajustement du degré d’autonomie des navires autonomes par l’apport d’un système d’aide aux prises des décisions pour les pilotes afin de les assister.

Unobtrusive Monitoring of Heart Failure and its Effect on Ballistocardiograph

It is important that heart failure patients monitor their condition at home. We are exploring devices that can improve the self-monitoring required of patients and send this information back to their doctors. A technology that we are
testing is ballistocardiography (BCG). BCG is a mechanical vibration generated by your heart and is recorded using a specialized floor tile. It is a convenient way to collect information without any attachment to the skin and
without requiring the patient to wear any external device on the body. To have a working device, algorithms to extract health parameters such as heart rate are necessary. Through this project, these autonomous algorithms
will be developed and incorporated as part of the partner institution’s (Balliscor Inc) final product.

Development of Novel Toxicity Testing Assays for Fishes

It’s estimated that more than half of all fish species in Canada are threatened by anthropogenic pressures, including pollution. Two chemical classes that are ubiquitous in freshwater ecosystems- polycyclic aromatic hydrocarbons (PAHs) and benzotriazole ultraviolet stabilizers (BUVSs) – can cause toxicity to early life-stages of fishes by activating of the aryl hydrocarbon (Ah) receptor protein. However, not all fish species are equally sensitive to these chemicals, and it is not possible to conduct traditional toxicity testing with all species of fish. Through this Mitacs GRA, two HQP will receive training to develop high-throughput assays to determine toxicity of PAHs and BUVSs to any fish species from which a tissue sample can be obtained, including threatened or endangered species. Assays can then be used for other chemicals that act via the Ah receptor protein. Data from these assays can be used to understand the risks that some classes of chemicals pose to Canadian fish species.

Modelling pollutant removal processes for an underground detention chamber system

This project will determine if underground detention systems provide an equivalent level of service for stormwater treatment as stormwater management ponds. This will be achieved through water quality measurements collected from a StormTrap system and through the development of a pollutant-transfer model. The intern will work with both the Toronto Region Conservation Authority and Con Cast Pipe. Since the technology is relatively new, if it can be shown that the StormTrap system provides the same benefits as or exceeds the standards provided by stormwater management ponds then it is more likely to be the chosen solution ultimately leading to more manufacturing of pre-cast concrete products in Ontario. Municipalities benefit from this project by potentially having an alternative to stormwater management ponds.

Optimal Design of Medium Voltage Permanent Magnet Synchronous Motor Drive System for Submersible Pumps Application

In order to make the drilling tools more efficient and easier to control, some methodologies inspired by former researches are used in designation of the control system for electrical submersible pumps working underground.
This system will be consuming less energy than former ones since the thermal loss is reduced, which would be realized via a converter structure with hybrid switches, verified to be feasible for heat balancing among theswitches. And it will be faster on achieving predictive data used for the control loop, by using the advanced algorithm taking 3 voltage vectors instead of all 7. And also, it will make the transmissions between control strategies used for different voltage ranges smoother through a reliable flag signal implemented to judge the status of the applied voltage. Besides, the proposed system would be more environmentally friendly.
