TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991 The aerodynamic characteristics of reaction stages of a large steam turbine have been studied for the basis of performance improvement. For the first step, the characteristics of a single reaction stage with typical reaction blading were studied by two-dimensional low-speed cascade tests and single-stage air turbine tests.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.
