The paper deals with sonic surface in a modern turbine wheel consisting of non-prismatic ultra long blades.The whole inter-blade channel is choked.Different positions and shapes of the sonic line in particular cross-sections along the blu dot wall hook span are observed.The sensitivity of sonic line formation to small changes of effective shape of
Not all accidental releases of flammable gases and vapours create explosions; most releases do not find an ignition princess jasmine silhouette source and of those that do ignite, most of them generate low or moderate overpressure only (deflagrative combustion).However, when certain conditions are satisfied, deflagration to detonation transition (D

Abstract Previous studies of ancient jade using portable X-ray fluorescence (pXRF) have mostly focused on mineral identification, alteration status and provenance determination.It is usually used as an auxiliary instrument for spectroscopic detection with finer resolution.However, there is no substitute for the efficiency and stability of pXRF in-s
