Volume 10A: Turbomachinery — Axial Flow Fan and Compressor Aerodynamics.
The predecessor of this paper (GT2021-60012) introduced the Symmetry (S’-) framework of compressor map representation. This framework exhibits a natural simplicity of expression in comparison with the common BETA framework, enables relatively simpl

We developed a method that enables one to correct solar blind pyrometer cavity temperature measurements for the system-sensor reflection error. The method is valid for measurements made on diffusely emitting and reflecting cavity surfaces when there

Patients with active Hodgkin's disease were found to have significantly lower levels of plasma bradykininogen than either normal subjects or those with inactive Hodgkin's disease. While low levels of bradykininogen have not been subjected to metaboli
