Europa's Neutral Sodium Exosphere Is Quasi‐Stable Over Decades

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Europa's sodium cloud is thought to be modified by its orbital longitude and by its plasma environment, which modulates with Jovian magnetic geometry. To explore and quantify sodium cloud variability, seven sets of Keck I/HIRES measurements are compared providing comprehensive coverage of orbital and magnetic geometry.

BALLISTICS FOR THE NEUROSURGEON

Neurosurgery, 2008
Craniocerebral injuries from ballistic projectiles are qualitatively different from injuries in unconfined soft tissue with similar impact. Penetrating and nonpenetrating ballistic injuries are influenced not only by the physical properties of the projectile, but also by its ballistics. Ballistics provides information on the motion of projectiles while

Modern thermoplastic (hot glue) versus organic-based adhesives and haft bond failure rate in experimental prehistoric ballistics

, 2021
The prehistoric production of composite technologies throughout human evolution was facilitated greatly by the use of adhesives. One such technology was projectile weaponry, which used adhesive to attach a stone point to a wooden shaft.

Self-consistent surface-temperature boundary condition for liquefying-fuel-based hybrid rockets internal-ballistics simulation

, 2021
A novel methodology for the calculation of the surface temperature of liquefying fuels typically burned in hybrid rockets is proposed. This procedure stems from the formulation of a fuel in-depth pyrolysis model coupled with the resolution of the thermo ...

Research on dynamic characteristics of interior ballistics process engraving based on the coupling method

The Physics of Fluids
Study of the engraving process is significant for interior ballistics. Due to the high transient and strong nonlinear characteristics of the engraving, research on the engraving mechanism is challenging.

Observation of ballistic holes

Physical Review Letters, 1988
We report the first direct observation of ballistic hole transport in semiconductors, via energy spectroscopy experiments. Light holes are preselected and injected via tunnelling into 31 nm thick p+ GaAs layers. About 10% of the injected holes have been found to traverse ballistically maintaining distributions ≈ 35 meV wide, with a mean free path of ...

Ballistic Trauma: Overview and Statistics – Wound Ballistics

2016
Wound ballistics is the specialty in ballistics dealing with the interaction of bullet and tissue, resulting in lesions when humans or animals are hit. The lesions depend on the velocity and mass of the bullet as well as its design. Bullets are divided into low- and high-velocity bullets.

Ballistic injury

Annals of Emergency Medicine, 1986
Wound profiles made under controlled conditions in the wound ballistics laboratory at the Letterman Army Institute of Research showed the location along their tissue path at which projectiles cause tissue disruption and the type of disruption (crush from direct contact with the projectile or stretch from temporary cavitation).
