Neurocognitive Performance Deficits Related to Immediate and Acute Blast Overpressure Exposure [PDF]
Frontiers in Neurology, 2019 Addressing the concerns surrounding blast injury for the military community is a pressing matter. Specifically, sub-concussive blast effects, or those blast effects which do not yield a medical diagnosis but can result in symptom reporting and negative ...

The Role of Very Low Level Blast Overpressure in Symptomatology [PDF]
Frontiers in Neurology, 2019 Blast overpressure exposure has been linked to transient, but measurably deteriorated performance and symptomatologies in law enforcement and military personnel. Overlapping sub-concussive symptomatology associated with the very low level blast overpressures (vLLB) but high sound pressure (

Role of Interfacial Conditions on Blast Overpressure Propagation Into the Brain. [PDF]
Front Neurol, 2020 The complex interfacial condition between the human brain and the skull has been difficult to emulate in a surrogate system. Surrogate head models have typically been built using a homogeneous viscoelastic material to represent the brain, but the effect of different interfacial conditions between the brain and the skull on pressure transduction into ...

Autonomic responses to blast overpressure can be elicited by exclusively exposing the ear in rats [PDF]
Journal of Otology, 2018 Blast overpressure has become an increasing cause of brain injuries in both military and civilian populations. Though blast's direct effects on the cochlea and vestibular organs are active areas of study, little attention has been given to the ear's ...

Effects of Primary Blast Overpressure on Retina and Optic Tract in Rats. [PDF]
Front Neurol, 2016 Blast has been the leading cause of injury, particularly traumatic brain injury and visual system injury, in combat operations in Iraq and Afghanistan. We determined the effect of shock tube-generated primary blast on retinal electrophysiology and on retinal and brain optic tract histopathology in a rat model.

Spatial Intracranial Pressure Fields Driven by Blast Overpressure in Rats. [PDF]
Ann Biomed EngAbstractFree-field blast exposure imparts a complex, dynamic response within brain tissue that can trigger a cascade of lasting neurological deficits. Full body mechanical and physiological factors are known to influence the body’s adaptation to this seemingly instantaneous insult, making it difficult to accurately pinpoint the brain injury mechanisms.

The Functional and Structural Changes in the Basilar Artery Due to Overpressure Blast Injury [PDF]
Journal of Cerebral Blood Flow and Metabolism, 2015 Overpressure blast-wave induced brain injury (OBI) leads to progressive pathophysiologic changes resulting in a reduction in brain blood flow, blood brain barrier breakdown, edema, and cerebral ischemia. The aim of this study was to evaluate cerebral vascular function after single and repeated OBI.

Equivalent method for calculating internal blast loads in cylindrical lattice shell structure [PDF]
Scientific ReportsIt is crucial to improve the calculation efficiency of internal blast loads of a long-span spatial steel structure. This study develops an equivalent model for such loads using a one-way inclined single-layer cylindrical lattice shell structure as a case
