Explosive crystallization mechanism of ultradisperse amorphous films [PDF]
The explosive crystallization of germanium ultradisperse amorphous films is studied experimentally. We show that crystallization may be initiated by local heating at the small film thickness but it realizes spontaneously at the large ones.

Controls on explosive-effusive volcanic eruption styles
One of the biggest challenges in volcanic hazard assessment is to understand how and why eruptive style changes within the same eruptive period or even from one eruption to the next at a given volcano.

Safety analysis on truing process of solid propellant
In order to investigate safety character of solid propellant, the truing process was analyzed by a thermal-mechanical coupled finite element method. Based on the viscoelastic integral constitutive relation, the temperature response in truing process was ...

In the present paper it is shown that if a flow satisfies Smale’s Axiom A’ {\text {A’}} and there is a cycle on its nonwandering set Ω \Omega , then the flow is not Ω \Omega -stable. This is done by “blowing up” the nonwandering set with a small perturbation.

The objective of the present paper is to describe the clinical and computed tomography features of ′explosive pleuritis′, an entity first named by Braman and Donat in 1986, and to propose a case definition. A case report of a previously healthy, 45‐year‐old man admitted to hospital with acute onset pleuritic chest pain is presented.
