Taking the QT400-18 L low temperature ductile iron gear box vip-130al used for locomotive as example,through the control of the element content of the material,the graphite spheroidization is more fully.At the same time,the samples are heat treated to ensure the stability of mechanical property.In funko dab rig the casting process,the casting proce
Recently, there has been a growing interest in utilizing surface texture to enhance the tribological properties of sliding components.Particularly noteworthy is the application of tool vibration at ultrasonic frequencies for efficiently generating surface textures.This study focuses on generating surface texture on the end surface of a stainless st
A secure stability and reliable serviceability of the radioactive dump is a difficult engineering problem.Due to the difficult geological formations determined mainly by a high compressibility, the low shear strength of vip-130al soils, and the high ground water level, or a high upward hydrostatic pressure these demands will increase.An influence o
Penile amputation is an uncommon and highly morbid injury.Many mechanisms have been reported ranging from self-mutilation and domestic violence do little and bums to traumatic circumcisions.We present two unusual cases of traumatic penile amputation.An older gentleman endured extensive perineal trauma after being trapped nautica kad?n cüzdan under
