An overview of explosive volcanism on Mars

, 2020
Decades of space exploration reveal that Mars has been reshaped by volcanism throughout its history. The range of observed volcanic landforms shows that effusive and explosive eruptions have occurred, albeit unevenly in time and space.

Expert Perspectives on the Performance of Explosive Detection Canines: Operational Requirements

Animals, 2021
Explosive detection canines (EDC) play an important role in protecting people and property. The utilization of and research on EDCs is often based on personal experience or incomplete knowledge. EDC practitioners (handlers, trainers, and leaders) possess

Predicting Miner Localization in Underground Mine Emergencies Using a Hybrid CNN-LSTM Model with Data from Delay-Tolerant Network Databases

Applied Sciences
Underground mining environments are highly hazardous, often prone to gas explosions, cave-ins, and fires that may trap miners during emergencies. The accurate, real-time localization of miners is vital for effective self-escape and rescue operations ...

Explosive Collisions at RHIC? [PDF]

, 2001
Motivated by experimental results from RHIC, we suggest how a condensate for the Polyakov loop might produce explosive behavior at the QCD phase transition.

Explosive Welding of Aluminum, Titanium and Zirconium to Copper Sheet Metal [PDF]

, 1985
The main material properties affecting the explosive weldability of a certain metal combination are the yield strength, the ductility, the density and the sonic velocity of the two metals. Successful welding of the metal combination depends mainly on the

Explosive Magnetotail Activity

Space Science Reviews, 2019
Modes and manifestations of the explosive activity in the Earth’s magnetotail, as well as its onset mechanisms and key pre-onset conditions are reviewed. Two mechanisms for the generation of the pre-onset current sheet are discussed, namely magnetic flux

THE STRUCTURES AND NONUNIFORM ACCELERATION [PDF]

Fiabilitate şi Durabilitate, 2012
This paper deals with stress calculation procedures which can be applied to axially symetrical structures, nonuniformly accelerated. The equations governing the stress status and the basic hypotheses are presented. Also, the mathematical model is applied
