Hepatic parenchymal rupture is a rare but potentially fatal condition that can be caused by trauma, iatrogenic factors, spontaneous causes, etc.This case report describes the diagnostic and therapeutic steps employed in a patient with spontaneous hepatic parenchymal rupture.An older woman came to the emergency department with diffuse stomach pain.A
In this study all-position automatic tungsten inert gas (TIG) welding was exploited to enhance quality and efficiency in the welding of copper-nickel alloy pipes.The mathematical models of all-position automatic TIG weld bead shapes were conducted by the response surface method (RSM) on the foundation of French Door Latch central composition design
In order to improve the penetration and survival performance of hypersonic vehicles in the unpowered glide section under incomplete guidance and detection information or interference of detection equipment, this paper establishes Accessories a dynamic model of hypersonic vehicles in the glide section.The trajectory is optimized using sequential con
We propose a novel scheme for designing and generating kaleidoscope-structured vector optical fields Stockings (KS-VOFs) by analogy with the principle of multiple mirror reflection in a kaleidoscope.For KS-VOFs with symmetric polarization states, we show the symmetry properties of the focal fields with various shapes for different applications.The
A novel coupled wheel/track mechanism is proposed to overcome the complexity and limited applicability of conventional coupled wheel/track robots.The mechanism is based on the design of a tracked off-road robot, where the track is separated from the driving wheel Zanussi ZHV94750BA Angled 90cm Black Glass Chimney Cooker Hood and the load-bearing wh
