Long, Ph.D. CONTRACTING ORGANIZATION: The Geneva Foundation Tacoma, WA 98402 REPORT DATE: November 2013 TYPE OF REPORT: Final PREPARED FOR: U.S. Army Medical Research and Materiel Command Fort Detrick, Maryland 21702-5012 DISTRIBUTION STATEMENT: Approved for public release; distribution un...

Due to the flammability and explosion characteristics of the propane vapor cloud, a nearby propane tank farm could possibly present a significant risk to the operation of nuclear power plants. Accidental releases of propane may occur in the propane supply pipeline, at the propane storage tanks, or on the propane transportation routes due to propane transport trailer truck accidents. Loss of con...

This paper investigated the effectiveness of a vent burst door in isolating shock waves gas explosions coal mines and to reveal mechanisms explosion overpressure. A 17.5 m × φ 0.63 columnar test duct with similar shape roadways was designed. Explosion overpressure propagation characteristics effects methane concentration at different locations along without were experimentally investigated. The...

This study focuses on a specific problem related to the surface uplift induced by the injection of CO2 at depth. The adopted methodology includes the development of a mathematical model that incorporates the deformable behaviour of storage media and the flow of two immiscible fluids (CO2 and water) within the aquifers while the surface rock or caprock layer is modelled as a thin plate. Governin...

Explosive blast results in multiple organ injury and polytrauma, the intensity of which varies with the nature of the exposure, orientation, environment and individual resilience. Blast overpressure alone may not precisely indicate the level of body or brain injury after blast exposure. Assessment of the extent of body injury after blast exposure is important, since polytrauma and systemic fact...
