Experimental investigations of coal dust-inertant mixture explosion behaviors [PDF]
, 2011 An experimental investigation was carried out on coal dust-inertant mixture explosions. Tests of explosion severity and flammability limit were conducted by using the Siwek 20 L vessel and influences of ignition energy, coal dust calorific value, coal ...

American Journal of Botany, Volume 113, Issue 8, August 2026.Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Clinical and Translational Allergy, Volume 16, Issue 8, August 2026.ABSTRACT Background Airway allergies affect 20%–30% of the global population, with pollen and fungal spores representing major environmental triggers. Although fungal spores are far more abundant than pollen, their allergenic role—particularly from phytopathogenic rust fungi such as birch rust (BR)—remains poorly understood.

No Place to Hide? Regional Resilience and Vulnerability to Global Catastrophic Risk
Global Challenges, Volume 10, Issue 8, August 2026.No location on Earth withstands every global catastrophe. This review maps the geographic, institutional and infrastructural factors shaping resilience to nuclear, volcanic and impact winters, infrastructure loss and pandemics. Geographic isolation, food self‐sufficiency, strong governance and decentralization improve resilience across scenarios ...

Experimental Study on the Influence of Initial Pressure on Explosion of Methane-coal Dust Mixtures [PDF]
, 2013 Methane-coal dust explosion belongs to chemical explosion which always directly causes fire disasters. When it comes to coal mine, the gas explosion easily leads to extensive burning and forms large area stereo fire finally, due to the big blast power ...
