The results of the analysis statistical data on accidents at Russian mines caused by explosions in workings space have shown that methane-dust-air mixtures underground coal are most severe terms consequences. A detailed literature sources showed total number prevails share hybrid mixtures, i.e. with simultaneous participation gas (methane) and dust, as well possible or partial involvement dust....

I suggest that the recently observed hot-dust elongated structure likely engulfs neutron star (NS) remnant of supernova (SN) 1987A was shaped by jets NS launched shortly after it acquired its natal kick velocity. take axis two post-kick to be along long dimension structure, which term bipolar lobe. The jittering explosion mechanism accounts for misalignment and main-jets ejecta. For shape lobe ...

the risks of fire and explosion in oil and gas industry need to be managed. the objectives of the present study were to assess the risk of fire and explosion in iso-max unit of tehran oil refinery using dow’s fire and explosion index and to study the influences of the controlling methods. the latest version of dow fire and explosion index guideline was applied to calculate the fire and explosio...

the current manuscript presents the validation of smoothed particle hydrodynamics (sph) techniques for wave generation by underwater explosion, utilizing the so-called dualsphysics numerical model. this numerical method is used to analyze generated waves which are initiated by man-made or natural explosions below free surface level of sea. in spite of the modeling limitations (e.g. absence of o...

Post-mortem and in-situ evidence is presented in favor of the generation high-velocity solid dust during explosion-like interaction runaway electrons with metallic plasma-facing components FTU. The freshly-produced source secondary de-localized wall damage through impacts that lead to formation craters, which have been reproduced dedicated light gas gun impact tests. This novel mechanism, poten...

Large discrepancies are found between observational estimates and theoretical predictions when exploring the characteristics of dust formed in ejecta core-collapse supernovae. We revisit scenario production typical supernova first 3000 days after explosion, with an improved understanding evolving physical conditions distribution clumps. The generic, nonuniform within was determined using that, ...

Motivated by recent models involving off-centre ignition of type Ia supernova explosions, we undertake three-dimensional time-dependent radiation transport simulations to investigate the range of bolometric light curve properties that could be observed from supernovae in which there is a lop-sided distribution of the products from nuclear burning. We consider both a grid of artificial toy model...

What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now often known as the “singularity”. The basic argument here was set out by the statistician I. J. Good in his 1965 article “S...

The information explosion has led to problems and possibilities in many areas of society, including that of law enforcement. In comparing individual criminal investigations on similarity, we seize one of the opportunities of the information surplus to determine what crimes may or may not have been committed by the same group of individuals. For this purpose we introduce a new distance measure t...
