Thermal persistence and physicochemical modification of inorganic gunshot residue (IGSR)

Journal of Forensic Sciences, EarlyView.
Abstract In the medicolegal context, GSR analysis plays a key role in clarifying the dynamics of firearm‐related deaths, including lesion identification and firing distance determination. However, postmortem alterations of the body, such as thermal exposure, may influence the analysis of lesions and complicate interpretation.

High energy ballistic and fracture comparison between multilayered armor systems using non-woven curaua fabric composites and aramid laminates

Journal of Materials Research and Technology, 2017
For personal protection against high kinetic energy projectiles, multilayered armor systems (MAS) are usually the best option. They combine synergistically the properties of different materials such as ceramics, composites and metals. In the present work,

The Unintended Consequences of German Deterrence

Global Policy, EarlyView.
ABSTRACT Germany's evolving deterrence posture boils down to continued participation in NATO nuclear sharing and an ambitious conventional rearmament program. Due to its non‐nuclear status and a result of decades of underinvestment, Germany prioritizes modern conventional weapons.

The Stability‐Instability Paradox and the Evolving Balance of Terror in the Middle East

Middle East Policy, Volume 33, Issue 4, Winter 2026.
Abstract In launching its war on Iran, Washington has committed a grave mistake by allowing a weakened Islamic Republic to reconstitute a regional balance of terror. This article shows how the Cold War‐era stability‐instability paradox has been restored in a new form, creating an equilibrium that discourages open warfare while reducing the advantages ...

A Thoracic Mechanism of Mild Traumatic Brain Injury Due to Blast Pressure Waves [PDF]

, 2008
The mechanisms by which blast pressure waves cause mild to moderate traumatic brain injury (mTBI) are an open question. Possibilities include acceleration of the head, direct passage of the blast wave via the cranium, and propagation of the blast wave to

Simulation and Analysis of Stiffened Auxetic Honeycombs Having Enhanced High Impact Velocity Response

Applied Research, Volume 5, Issue 5, October 2026.
The ballistic resistance of auxetic re‐entrant honeycomb structures can be significantly improved through geometric tailoring and structural reinforcement. Vertical and horizontal stiffening ribs enhanced the ballistic performance, increasing the energy absorption efficiency by 119.45% and the projectile velocity reduction by 281.36%, ultimately ...
