Low-cost blast wave generator for studies of hearing loss and brain injury: Blast wave effects in closed spaces

Numerical Investigation of Circular Plates Deformation under Air Blast Wave

In the current research the maximum deflection of circular plates made of AA5010 and AA1100 alloys under blast load was investigated. Shock waves were produced by exploding a spherical charge in different distances from the center of plates. The ABAQUS software uses conwep equation for blast loading analysis. It was found the results of these simulations have about 30% to 40% inaccuracy in comp...

Mechanisms of Hearing Loss after Blast Injury to the Ear

Given the frequent use of improvised explosive devices (IEDs) around the world, the study of traumatic blast injuries is of increasing interest. The ear is the most common organ affected by blast injury because it is the body's most sensitive pressure transducer. We fabricated a blast chamber to re-create blast profiles similar to that of IEDs and used it to develop a reproducible mouse model t...

Blast-wave Snapshots from Rhic

I present fits with the so-called blast-wave model to single-particle spectra and HBT correlations from Au+Au collisions at a CMS energy of 130 AGeV. There is only little choice of freeze-out temperature and transverse flow velocity for which the model fits both the identified spectra and the correlation radii just well enough not to be excluded. The observed steep M⊥ dependence of Rside leads ...

Blast Brain Injury: Quantifying Axonal Injury Due to Primary Blast

This review includes a study of the cause of Necrotizing Fasciitis (NF) by Group A Streptococci (GAS), the existing treatment of the infection, and the proposal of a novel therapy. The purpose of this review is to determine the microbiology and pathogenesis of NF in addition to how the treatment may be modified to best target the infecting pathogens. Existing treatments include rapid surgical d...
