Wind Turbine Blade Material Behavior in Abrasive Wear Conditions.

The wind turbine blades are exposed, during functioning, to the abrasive wear generated by the impact with air-borne sand particles. In this work, samples of a commercial wind turbine blade, made of a multi-layered composite material, are subjected to abrasive wear tests, using an air streamed wearing particles test rig. Following the analysis of the tests' results was found that the only protection against failure of the blade by abrasive damage is the surface layer.

Alterations in LDL and HDL after an ischemic stroke associated with carotid atherosclerosis are reversed after 1 year.

Approximately 20% of ischemic strokes are attributed to the presence of atherosclerosis. Lipoproteins play a crucial role in the development of atherosclerosis, with LDL promoting atherogenesis and HDL inhibiting it. Therefore, both their concentrations and their biological properties are decisive factors in atherosclerotic processes.

Monitoring poultry social dynamics using colored tags: Avian visual perception, behavioral effects, and artificial intelligence precision.

Artificial intelligence (AI) in animal behavior and welfare research is on the rise. AI can detect behaviors and localize animals in video recordings, thus it is a valuable tool for studying social dynamics. However, maintaining the identity of individuals over time, especially in homogeneous poultry flocks, remains challenging for algorithms.

Short-Term Changes in Food Spatial Distribution by Zoo Husbandry Practices Increase Agonism and Affect Feeding Behavior in Chilean Flamingos (): A Case Study.

Short-term modifications to animals' enclosures, stemming from zoo husbandry practices, can significantly impact animal behavior and, consequently, their welfare. In this case study, we examined a captive-bred population of 23 adult Chilean flamingos () during a non-breeding season to evaluate whether short-term alterations in the spatial distribution of feeders would affect the birds' feeding and agonistic behaviors. Initially, we developed an ethogram to establish baseline behavioral data.

Potential of accelerometer tags for monitoring of Japanese quail () reproductive behaviour.

1. Monitoring behavioural dynamics in complex animal environments, such as poultry breeding facilities, poses a challenge. Utilising technological approaches, such as accelerometers, offers a solution to assess long-term changes in reproductive activity at an individual bird level.
