Explosive blast has been extensively used as a tactical weapon in Operation Iraqi Freedom (OIF) and more recently in Operation Enduring Freedom(OEF). The polytraumatic nature of blast injuries is evidence of their effectiveness,and brain injury is a frequent and debilitating form of this trauma. In-theater clinical observations of brain-injured casualties have shown that edema, intracranial hem...
Mobile overpressure fans are popular tools used in rescue and extinguishing operations carried out by Fire Protection Units. They for exhaust venting buildings from harmful products of thermal decomposition occurs due to fire. Health human life may depend on the proper this type equipment. The aim article is compare results real research with numerical analysis. Scientific Research Centrum – Na...
Abstract The problem of leakage superheated liquids such as LPG, LNG, LCG and AML is widely valued in the process industry. key to liquid storage transportation prevent cracks due unexpected situations tank overpressure, pipe corrosion violent collisions. When wall ruptures, air pressure inside drops sharply a phase change occurs degraded maintain energy balance. instantly evaporates into gas, ...
The case histories of five patients who experienced blast overpressure in excess of 200-dB peak pressure level are presented. Despite the significance of the sound pressure levels received in a military training accident and the severe injuries that resulted from the blast, these individuals experienced substantial improvement of hearing 1 year later. Undoubtedly, successful surgical interventi...
Emotional disorders are a common outcome from mild traumatic brain injury (TBI) in humans, but their pathophysiological basis is poorly understood. We have developed a mouse model of closed-head blast injury using an air pressure wave delivered to a small area on one side of the cranium, to create mild TBI. We found that 20-psi blasts in 3-month-old C57BL/6 male mice yielded no obvious behavior...
With the growing footprint of solid oxide fuel cell stacks, there is a need to extend the operating range of compressible gaskets towards lower stress levels. This article describes a method to manufacture SOFC seals by coating a compressible sealing material (Thermiculite 866) with glass to obtain good sealing performance even at compression stresses as low as 0.1 MPa. Glass layer can be coate...
Underwater blasts propagate further and injure more readily than equivalent air blasts. Development of effective personal protection and countermeasures, however, requires knowledge of the currently unknown human tolerance to underwater blast. Current guidelines for prevention of underwater blast injury are not based on any organized injury risk assessment, human data or experimental data. The ...
