Effect of Spruce Wood Density on Selected Fire-Technical Parameters during Thermal Loading

open access: yesApplied Sciences, 2023
The paper evaluates the effect of spruce wood density on the parameters of mass loss and mass loss rate during exposure to thermal load. The intention was to determine whether the effect of density is still evident after the application of flame ...

Impact of Heat Treatment of Spruce Wood on Its Fire-Technical Characteristics Based on Density and the Side Exposed to Fire

open access: yesApplied Sciences, 2022
The paper assessed the impact of the heat treatment of spruce wood, the (radial and tangential) side of the specimens exposed to fire, and the type of material (prism—higher density, floor—lower density) on the combustion process and the rate of fire ...

Crystallinity versus mass-loss rate in Asymptotic Giant Branch stars [PDF]

open access: yes, 2001
Infrared Space Observatory (ISO) observations have shown that O-rich Asymptotic Giant Branch (AGB) stars exhibit crystalline silicate features in their spectra only if their mass-loss rate is higher than a certain threshold value.

Magnetic Field, Dust, and Axisymmetrical Mass Loss on the AGB [PDF]

open access: yes, 1998
I propose a mechanism for axisymmetrical mass loss on the asymptotic giant branch, that may account for the axially symmetric structure of elliptical planetary nebulae.
