Évaluation du potentiel géothermique du cratère d'impact météoritique de Charlevoix (Canada)
Oviedo, Maria Jose — 2023-11-03 L'énergie géothermique s'impose comme une ressource propre et renouvelable, laquelle se distingue par son facteur de capacité supérieur et un approvisionnement constant en énergie, offrant une alternative pour le chauffage urbain et les serres en climats froids. Pour élargir l’accès aux ressources géothermiques, nous proposons d'étudier un nouveau type de gisement associé aux cratères d'impact météoritiques caractérisés par une fracturation intense de la roche. Ainsi, nous avons réalisé une étude du potentiel géothermique du cratère de Charlevoix, au Québec, dans le but de caractériser les propriétés thermohydrauliques des matériaux géologiques afin d'évaluer les mécanismes de transfert de chaleur et d’estimer la température en profondeur à l'aide de simulations numériques. Les propriétés thermiques et hydrauliques des échantillons de roc prélevés dans et autour du cratère ont été caractérisées en laboratoire à l'aide d'un scanner infrarouge et d'un porosimètre et perméamètre avec écoulement de gaz en régime transitoire pour des échantillons artificiellement fracturés. La perméabilité a été évaluée sur le terrain avec la méthode de Porchet dans deux forages. Les résultats indiquent que les roches anorthositiques sont isolantes en raison de leur faible conductivité thermique (1,7 W/mK). Les éléments radiogéniques présents dans le roc ont été trouvés en très faibles concentrations et ont un faible potentiel de génération de chaleur, inférieur à 1 µW/m3. Enfin, l'évaluation de la perméabilité des roches fracturées a résulté en des valeurs suffisamment élevées (environ 1.0E-14 m2) pour que la convection soit considérée comme un mécanisme potentiel de transfert de chaleur dans le cratère de Charlevoix. Des modèles numériques d'écoulement des eaux souterraines et de transfert de chaleur ont été développés pour estimer la température en régime permanent jusqu'à 10 km de profondeur dans deux sections transversales du cratère et pour déterminer les paramètres qui ont le plus d'impact sur la distribution de la température en subsurface. Les résultats montrent que la recharge des eaux souterraines profondes et la conductivité thermique du roc sont les paramètres qui ont le plus d'influence sur la distribution de température. Le gradient géothermique trouvé jusqu'à 3 km de profondeur à l'intérieur du cratère est d'environ 22 °C/km, tandis qu'à l'extérieur du cratère, il est d'environ 12 °C/km.

Données de l'Enquête sur l’endettement parmi les ménages Québécois (EEMQ)
Pugliese, Maude — 2023-11-02 L’Enquête sur l’endettement parmi les ménages Québécois (EEMQ) a été dirigée par Maude Pugliese, professeure à l’Institut National de la Recherche Scientifique. Elle vise à approfondir notre compréhension de l’endettement vécu par les ménages Québécois et à documenter la prévalence du surendettement au Québec. Le projet a été réalisé grâce au soutien des partenaires suivants: le ministère de l'Éducation (MEQ), le ministère de l'Immigration, de la Francisation et de l’Inclusion (MIFI), le ministère de la Santé et des Services sociaux (MSSS), le ministère du Travail, de l'Emploi et de la Solidarité sociale (MTESS), le ministère des Affaires municipales et de l'Habitation (MAMH), le Secrétariat aux aînés (SA-MSSS) et le Fonds de recherche du Québec – Société culture, dans le cadre du Programme Actions concertées du FRQSC (Action concertée de recherche sur la pauvreté et l’exclusion sociale phase IV).

CHASE - Child Active Transportation Safety and the Environment Restricted content
Hagel, Brent; Howard, Andrew; Macpherson, Alison; Fuselli, Pamela; HubkaRao, Tate; Rothman, Linda; Richmond, Sarah; Winters, Meghan; Cloutier, Marie-Soleil; Pike, Ian — 2023-10-19 Active transportation (AT), such as walking and biking, is a healthy way for children to explore their environment and develop independence. However, children can be injured while walking and biking and these injuries can be severe when children are hit by motor vehicles. Many Canadian cities make changes to the built environment (BE) (e.g., traffic calming features, separated bike lanes) to try and keep people safe. There is some research on how effective these changes are in preventing adult pedestrians and bicyclists from getting hurt, but very little research has been done to show how safe various environments are for children and youth. Our research program will study how features of the BE affect whether kids walk or bike to school and whether or not certain BE features increase or decrease their likelihood of getting hurt. Our program is unique because we are partnering with injury prevention professionals, provincial and municipal governments, environmental and not-for-profit organizations and traffic safety professionals who are in a position to help us better understand what features of traffic environments are dangerous or safe. Our team’s national scope will be invaluable in providing information regarding the variability in BE characteristics and is vital to producing evidence based recommendations that will increase safe AT.

Genetic variance in contrasting environments
So, Cameron; Sibolibane, Mia; Weis, Arthur — 2023-10-04 <p>The evolutionary response of a trait to directional selection depends upon the level of additive genetic variance. It has been long argued that sustained selection will tend to deplete additive genetic variance as favoured alleles approach fixation. Non-additive genetic variance, due to interactions among alleles within and between loci, does not immediately contribute to an evolutionary response, although shifts in the allele frequencies within and between interacting loci may convert interaction variance into additive variance. Here we consider the possibility that an environmental shift may alter allelic interactions in ways that convert nonadditive into additive genetic variance. Specifically, we performed experiments that used a Bayesian implementation of the animal model to estimate the additive, dominance, and maternal components of variance for a pedigreed population of <em>Brassica rapa</em>. One experiment was performed in a field that mimicked agricultural conditions from which the base population was drawn, while the other was performed in the benign conditions of a greenhouse. Although the additive genetic variance was elevated in the greenhouse condition, no consistent pattens emerged that would indicate a conversion of dominance variance. The unusually low genetic variance and broad confidence intervals for the variance estimates obtained through this analysis preclude definitive interpretations. Thus, we promote further investigation to determine if between-environment changes in additive genetic variance can be traced to conversion of nonadditive variance.</p> https://creativecommons.org/publicdomain/zero/1.0/

Battery Aging Dataset for 15 Minute Fast Charging of Samsung 30T Cells
Duque, Josimar; Naguib, Mina — 2023-09-25 This aging dataset was designed to be used for training/parameterization and testing of machine learning and conventional filter based state of charge and state of health estimation models. A number of characterization tests (HPPC, C/20 charge discharge, etc) are applied to each cell and are followed by repeating series of drive cycle discharges and a fifteen minute fast charge. The characterization and drive cycle tests are repeated until the battery cells reach 70% SOH (around 1500 to 2000 cycles). The rate of aging for each cell is different because each cell is fast charged using a different method (standard CC/CV, boost charge - higher current at low SOC, and two pulsed charge methods). The four cells tested are brand new 3Ah Samsung INR21700-30T lithium ion battery cells. The testing was performed in a thermal chamber at 25 degrees Celsius using an Arbin battery cycler.
