Experimental investigation of a viscoelastic liner to reduce under helmet overpressures and shock wave reflections

Frontiers in Bioengineering and Biotechnology
IntroductionShock wave overpressure exposures can result in blast-induced traumatic brain injury (bTBI) in warfighters. Although combat helmets provide protection against blunt impacts, the protection against blast waves is limited due to the observed ...

Primary blast wave protection in combat helmet design: A historical comparison between present day and World War I.

PLoS ONE, 2020
Since World War I, helmets have been used to protect the head in warfare, designed primarily for protection against artillery shrapnel. More recently, helmet requirements have included ballistic and blunt trauma protection, but neurotrauma from primary ...

Hearing Loss and Irritability Reporting Without Vestibular Differences in Explosive Breaching Professionals

Frontiers in Neurology, 2020
Background: Blast exposure is a potential hazard in modern military operations and training, especially for some military occupations. Helmets, peripheral armor, hearing protection, and eye protection worn by military personnel provide some acute ...

Rocket Exhaust Derived Surface Water Migration at Lunar Landing Sites

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Volatiles, especially water, are at the center of modern lunar explorations. They have various sources, including volcanism, asteroid/comet impacts, and Earth/solar wind implantations. However, due to the lack of in situ data, it has not been widely recognized that artificial activities, especially rocket exhaust, could significantly impact ...

A closer look at BLEVE overpressure

, 2015
International audienceThe overpressure produced by the boiling liquid expanding vapor explosion (BLEVE) is still not well understood. Various methods have been published on the overpressure modeling in the far field. They mostly differ by the modeling of

Temporal changes of neurobehavior in rats following varied blast magnitudes and screening of serum biomarkers in early stage of brain injury

Scientific Reports
Blast neurotrauma has been linked to impairments in higher-order cognitive functions, including memory, attention, and mood. Current literature is limited to a single overpressure exposure or repeated exposures at the same level of overpressure.

Altered expression of aquaporin 1 and aquaporin 5 in the cornea after primary blast exposure

Molecular Vision, 2019
Purpose: Our study aimed to determine whether the altered expression of biomarkers linked to corneal injuries, such as the edema-regulating proteins aquaporin-1 and aquaporin-5 (AQP1 and AQP5), occurred following primary blast exposure. Methods: Adult

Assessing Neuro-Systemic & Behavioral Components in the Pathophysiology of Blast-Related Brain Injury

Frontiers in Neurology, 2013
Among the U.S. military personnel, blast injury is among the leading causes of brain injury. During the past decade, it has become apparent that even blast injury as a form of mild traumatic brain injury (mTBI) may lead to multiple different adverse ...

Methodical approach to testing trench and communication trench revetments for resistance to air blast overpressure

Under modern conditions of combat operations on the territory of Ukraine, the issue of protecting personnel from the effects of unmanned aerial vehicles, ammunition, fragments, and blast waves from shell explosions is particularly important and relevant.

A multiscale approach to blast neurotrauma modeling: Part I - Development of novel test devices for in vivo and in vitro blast injury models

Frontiers in Neurology, 2012
The loading conditions used in some current in vivo and in vitro blast-induced neurotrauma models may not be representative of real-world blast conditions.
