Surface roughness of real operationally used compressor blade and blisk
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2019 Deterioration of axial compressors is in general a major concern in aircraft engine maintenance. Among other effects, roughness in high-pressure compressor reduces the pressure rise and thus efficiency, thereby increasing the specific fuel consumption of

Arthritis Care &Research, EarlyView.Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain, and magnetic resonance imaging–confirmed midfoot BMLs ...

Arthritis Care &Research, Accepted Article.Objective Ultrasound (US) has been proposed as a potential tool for assessing skin fibrosis in systemic sclerosis (SSc). However, a large‐scale comparison of US‐based assessment with histological markers of skin fibrosis has not been reported. We evaluated the US‐based skin assessments for their face validity (differentiation between involved SSc and ...
