Fire eruption (also known as ‘blow-up’ or ‘flare-up’) is a very dangerous aspect of wildland fire behaviour. It poses a significant threat to the safety of wildland fire-fighters and complicates the broader problem of wildfire risk management in complex terrain. Despite the seriousness of eruptive fire events, operational wildland fire spread models generally do not account for the possibility ...

awareness of the effects of fire on various aspects of an ecosystem after the fire,is important for range management. changes in soil physical and chemical propertiescaused by fire can be the cause of changes in the vegetation. in this study, effects of fire onphysical and chemical characteristics of soil were investigated. this research was carriedout in a randomized block design method in the...

We have used multi-wavelength observations of high precision to derive the space velocity and compute the orbit around the Galactic Centre of the prototype X-ray binary Scorpius X-1. An origin in the local spiral arm of the Milky Way is ruled out. The galactocentric kinematics of Scorpius X-1 is similar to that of the most ancient stars and globular clusters of the inner Galactic halo. Most pro...
