In this study, under the open-close conditions of a roadway outlet, ANSYS/LS-DYNA was used to build models explosions on roadways with 0° and 90° bending angles, compare analyze shock wave propagation characteristics variation laws. Combined damage degree classification overpressure human body, destructive effect zoning explosion in condition opening closing entrance studied. The results showed...

Evolution of adiabatic remnants of an aspherical supernova explosion in uniform medium are considered. Thermal X-ray emission of such remnants are investigated. It is shown that integral thermal X-ray characteristics (X-ray luminosity and spectrum) of the objects do not allow us to reveal the assymetry in the explosion because these characteristics are close to their Sedov counterparts. Surface...

We propose that a γ-ray burst in one member of a binary may induce a supernova-like explosion of a close, white-dwarf companion. Such explosion might be brought about in rather light companions, which cannot undergo the standard accretion-induced explosion. This would give some GRB-associated supernova an appearance rather unlike that of the typical Type I. GRB 980425, if indeed associated with...

Stapes fractures without other ossicle problems are rare and ossicle problems due to explosion pressure are also rare. We describe a very rare case of stapes anterior crural fracture resulting from a land mine explosion. As this case suggests, a close examination of the ossicles is necessary during an exploration tympanotomy.

We suggest that a neutron star with a strong magnetic field, spiraling into the envelope of a companion star, can generate a “companion induced SN-like off-center explosion”. The strongly magnetized neutron star (“magnetar”) is born in a supernova explosion before entering into an expanding envelope of a supergiant companion. If the neutron star collapses into a black hole via the hypercritical...

Background: Fire and explosion hazards are extremely important in processing units. This study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company. Materials and Methods: The present qualitative case study was conducted using Dow’s index in 2015. The fire and explosion hazard index...
