Brain swelling is a serious condition associated with an accumulation of fluid inside the brain that can be caused by trauma, stroke, infection, or tumors. It increases the pressure inside the skull and reduces blood and oxygen supply. To relieve the intracranial pressure, neurosurgeons remove part of the skull and allow the swollen brain to bulge outward, a procedure known as decompressive cra...

This study combined finite element method (FEM) simulations and physical experiments to develop a novel cold bulging process, with the aim of studying mitigating quenching residual stresses in 2A14 tapered cylinder forgings. The samples underwent at different ratios (0–4.0%) evaluate stress reduction performance (via hole-drilling strain-gauge method) improvements their mechanical properties. F...

Laser flexible shock micro-bulging (LFSB) is a novel micro fabrication technology, which combines laser dynamic forming and flexible die forming, which is a type of high strain rate micro-forming. The LFSB of 304 stainless steel foils was investigated in this paper. Experimental and simulated results indicated that the bulging depth and thickness thinning rate of bulging parts increased with an...

Bulk endocytosis contributes to the maintenance of neurotransmission at the amphibian neuromuscular junction by regenerating synaptic vesicles. How nerve terminals internalize adequate portions of the presynaptic membrane when bulk endocytosis is initiated before the end of a sustained stimulation is unknown. A maturation process, occurring at the end of the stimulation, is hypothesised to prec...

.Hot metal gas forming of tubes can be used in various industries such as automotive and aerospace industries. In this process tube is formed at elevated temperatures, by using gas instead of fluid pressure. Lower required pressure and low power are its advantages in comparison to hydroforming process. In this paper, a hot metal gas bulging process of an aluminum alloy tube has been investigate...
