We describe a modification of a previously described measurement-analysis protocol to determine the intrinsic properties of triaxial accelerometers by using a measurement protocol based on angular stepwise rotation in the Earth's gravitational field. This study was conducted with MEMS triaxial accelerometers that were co-integrated in four consumer-grade wireless microsensors. The measurements were carried out on low-cost rotation tables in different laboratories in different countries to simulate the reproducibility environment encountered in inter-comparisons of calibration capabilities.

Article Synopsis
  • Individuals exposed to wildfires can develop mental health issues, but supportive text interventions may help mitigate these effects over time.
  • The study focused on evaluating a text message support service (Text4Hope) over three months in Alberta and Nova Scotia after the 2023 wildfires, involving participants who completed surveys to assess their mental health before and after the intervention.
  • Results indicated significant improvements in wellbeing and reductions in symptoms of depression, anxiety, and PTSD, suggesting the effectiveness of text message support in promoting mental health resilience after disasters.

The Eurasian griffon vulture (), a widely distributed scavenger, plays a crucial role in ecosystem health by consuming decomposing carcasses. Scavengers have adapted to avoid disease from the rotting carrion they feed on, probably through a specialized gut microbiome. This study aimed to characterize the gut microbiome of (n = 8) present in two rehabilitation centers in mainland Portugal and evaluate their potential as reservoirs of pathogens.

Fish presence in tailraces is a remarkable management concern in operating hydroelectric power plants (HPP) in Brazilian rivers. Fish get blocked during upstream migration for spawning, and large shoals can last for days in the tailrace; however, the circumstances that attract fish throughout the year to this region are uncertain, especially during drought conditions. To unravel this uncertainty, we modeled the relationship between Pimelodus maculatus abundance and environmental and operational variables (N = 26) in monthly fishing campaigns at the Machadinho HPP (N = 18).
