Stall Margin Improvement in a Centrifugal Compressor through Inducer Casing Treatment
International Journal of Rotating Machinery, 2016 The increasing trend of high stage pressure ratio with increased aerodynamic loading has led to reduction in stable operating range of centrifugal compressors with stall and surge initiating at relatively higher mass flow rates.

Method of Improving Stability of a Highly-Loaded Axial Compressor Stage by Coupling Different Casing Treatments [PDF]
Journal of Applied Fluid Mechanics, 2022 Casing treatment is a powerful method for improving the stability of aircraft compressors. An optimized slot-type casing treatment was tested on the first rotor of a highly-loaded two-stage compressor, and the results showed that the casing treatment ...

Effect of a Recirculating Type Casing Treatment on a Highly Loaded Axial Compressor Rotor
International Journal of Turbomachinery, Propulsion and Power, 2019 The tip leakage flow over the blades of an axial compressor rotor adversely affects the axial rotor efficiency and can determine the onset of tip leakage stall.

Numerical Optimization of a Stall Margin Enhancing Recirculation Channel for an Axial Compressor
Fluids, 2019 A proof of concept is provided by computational fluid dynamic simulations of a new recirculating type casing treatment. This treatment aims at extending the stable operating range of highly loaded axial compressors, so to improve the safety of sorties of

THE TREATMENT OF AMBULATORY GYNECOLOGIC CASES. [PDF]
JAMA: The Journal of the American Medical Association, 1898 Sanger tells us that gynecology is the surgery of the female genitalia. His definition is neither exact nor complete, but it is clinically useful. As a matter of fact the first thing to be determined in every gynecologic case is the advisability of operation. A necessary subdivision of the question is at once apparent.

Migraine ? a suitable case for treatment? [PDF]
Neuropsychiatric Disease and Treatment, 2006 Headache disorders are common, with a lifetime prevalence of over 90% in all populations where they have been measured. So common, in fact, that a Global Campaign to Reduce the Burden of Headache was launched in 2004 to educate health care providers, the general public, and national governments to recognize that headache disorders are not trivial, that
