The various process parameters affecting the quality characteristics of the shock absorber during the process were identified using the Ishikawa diagram and by failure mode and effect analysis. The identified process parameters are welding process parameters (squeeze, heat control, wheel speed, and air pressure), damper sealing process parameters (load, hydraulic pressure, air pressure, and ...

abstract introduction: doppler echocardiography is used to evaluate global myocardial performance. an index of myocardial performance (tei index) can be of great prognostic value in heart failure. this study was performed to assess the correlation between tei index (ti) and left ventricular end diastolic pressure (lvedp). methods: the study group consisted of 38 patients. each patient underwent...
