Abstract In this study, the microstructure and corrosion resistance of high-nitrogen austenitic stainless steel welded joints with different heat inputs were investigated. A high input leads to a large width depth fusion pool low fraction δ-ferrite in weld sea. However, Cr-rich precipitates is formed under promotes formation δ-ferrite. Therefore, following tests, seam suffers severe intergranul...

Amongst all these resistive forces in a modern passenger car, depending on the driving conditions and tire specifications, about 20–30% of total fuel consumption is related to rolling resistance. The resistance vehicle still rather unknown research should be conducted able estimate it reliably accurately. This accuracy particularly necessary at scale single reduce consumption, considering that ...

Investigators model noncardiogenic pulmonary hypertension by constricting the pulmonary artery to increase right ventricular afterload. To investigate this model's validity, we compared the right ventricular afterload, quantified as pulmonary input impedance, created by constricting the pulmonary artery and by inducing a pulmonary microvascular injury (with glass beads infused into the pulmonar...
