Analysis of the effect mechanism of water and CH4 concentration on gas explosion in confined space
Journal of Saudi Chemical Society, 2021 In order to study the effect of water and CH4 concentration on gas explosion, a 20L spherical explosive device was used to carry out a water-containing gas explosion experiment, and the explosion simulation was carried out with CHEMKIN-PRO, the mechanism

Ω-Stable Limit Set Explosions [PDF]
Transactions of the American Mathematical Society, 1986 Certain diffeomorphisms of two-dimensional manifolds are considered. These diffeomorphisms have a finite hyperbolic limit set which contains a limit set cycle. The only nontransverse cycle connection in these cycles is a complete coincidence of one component of the unstable manifold of one periodic point with one component of the stable manifold of ...

Limitation of Atmospheric Composition by Combustion–Explosion in Exoplanetary Atmospheres [PDF]
The Astrophysical Journal, 2018 Abstract This work presents theoretical studies that combine aspects of combustion and explosion theory with exoplanetary atmospheric science. Super-Earths could possess a large amount of molecular hydrogen depending on disk, planetary, and stellar properties.

Translating whole‐genome doubling into precision medicine in cancer
Molecular Oncology, EarlyView.Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)

Comparative Analysis of Fire and Explosion Properties of Lycopodium Powder
Energies, 2023 Lycopodium (L.) clavatum powder, due to its uniform particle size distribution and low equilibrium moisture content, is often used as a reference material and a calibration benchmark for dust combustion and dust explosion studies.
