Obstructing the passage of blast waves is an effective method mitigating pressures downstream obstacle. To this end, interaction between a wave and simplified structural shape, such as cylinder, has been widely investigated to understand complex flow pattern that ensues around The patterns include interference zones incident wave, diffracted other secondary in region. Such are responsible for c...

BACKGROUND Improvised explosive devices are a common feature of recent asymmetric conflicts and there is a persistent landmine threat to military and humanitarian personnel. Assessment of injury risk to the spine in vehicles subjected to explosions was conducted using a standardized model, the Dynamic Response Index (DRI). However, the DRI was intended for evaluating aircraft ejection seats and...

Mild traumatic brain injury, or concussion, is associated with a range of neural changes including altered white matter structure. There is emerging evidence that blast exposure-one of the most pervasive causes of casualties in the recent overseas conflicts in Iraq and Afghanistan-is accompanied by a range of neurobiological events that may result in pathological changes to brain structure and ...

Explosions will, in most cases, generate blast waves. While simple models (e.g., Multi Energy Method) are useful for simple explosion geometries, most practical explosions are far from trivial and require detailed analyses. For a reliable estimate of the blast from a gas explosion it is necessary to know the explosion strength. The source explosion may not be symmetric; the pressure waves will ...

Blood‐brain barrier (BBB) is the mechanism that isolates the delicate environment of brain from circulating blood flow. The BBB dysfunction, present in almost all cases of traumatic brain injury (TBI), including blast‐induced TBI (bTBI), triggers a cascade of events leading to cognitive and behavioral impairments. However, it is still not known if the rupture of BBB in bTBI is due to the pressu...
