Analysis of dynamic stall using unsteady boundary-layer theory [PDF]
The unsteady turbulent boundary layer and potential flow about a pitching airfoil are analyzed using numerical methods to determine the effect of pitch rate on the delay in forward movement of the rear flow reversal point.

Dynamic stall modeling of a wind turbine airfoil at various stall-induced vibration zones
Frontiers in Energy ResearchThe present work entails investigation of the unsteady aerodynamic characteristics of a wind turbine airfoil operating in four stall-induced vibration (SIV) regimes, including normal (SIV-1) and reverse (SIV-2) flow conditions. We conducted computational

British Journal of Clinical Pharmacology, EarlyView.Abstract Aims Children with primary immunodeficiency (PID) and secondary antibody deficiency (SAD) often require immunoglobulin replacement therapy due to low plasma immunoglobulin G (IgG) levels and recurrent infections. Existing pharmacokinetic models for immunoglobulin in PID patients predominantly focus on adults, with limited attention to ...

British Educational Research Journal, EarlyView.Abstract This paper explores the challenges and opportunities surrounding the recruitment and retention of minority ethnic teachers in England. Drawing on interview data from 33 teachers and school leaders of diverse ethnic backgrounds, it investigates whether racialised barriers identified in earlier research have shifted in the current context of ...
