Penetrating craniocerebral trauma is an injury in which a projectile violates the skull but does not exit. The significance of penetrating injuries to the head depends largely on the circumstances of the injury, the velocity of impact, and attributes of the projectile. While most penetrating head injuries are caused by firearms, lower-velocity mechanisms of penetrating brain injury present uniq...

The kinetic excitation of electrons upon bombardment of a solid surface with energetic ions is investigated. Using a metal-insulator-metal junction, hot electrons produced by the projectile impact are detected with excitation energies well below the vacuum level. The results provide information that cannot be accessed by electron emission experiments. The observed tunneling current depends on t...

Abstract Different metal matrix ceramic composite plates were manufactured using different diameter balls. The ballistic resistance of these investigated by firing 12.7mm, 25mm armor-piercing incendiary (API), and 200 standard explosively formed projectile(EFP). tests results showed that balls with higher mechanical properties performed better resistance, in the meantime, there was a correlatio...

Pulsatile lavage is a high-pressure irrigation treatment commonly used in the debridement of wounds. The risk of exposure to bloodborne pathogens and contaminants using high-pressure irrigation has been well documented in the literature. Projectile droplets and aerosolized fine droplets may form and spread, potentially contaminating the treatment facility and infecting personnel. A new devic...

A time-dependent close-coupling method is developed to treat the double ionization of helium by fast bare ion collisions. At high incident energies, charge transfer to the projectile is quite small, so that the two-electron wavefunction remains centred on the target, subject to a time-dependent projectile interaction. A multipole expansion of the projectile–atom interaction includes monopole, d...

Products from the reaction of 45 MeV/A beams of S on targets of Sn were measured with the Forward Array Using Silicon Technology (FAUST) [1]. Charged particle identification and energy calibration of the array have been completed [2]. The design of the FAUST Array selects heavily against particles emitted from a target like source. For peripheral reactions, this allows for relatively straightfo...
