Updating the aerodynamic resistance for subsurface ventilation [PDF]

, 2019
For the safety works in the mines good ventilation is one of the main requirements. For miners’ performance, the subsurface ventilation creates healthier and more hygienic conditions. Mine ventilation has always belonged to the field of mining. Moreover,

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Beyond Climate Security: Reframing the Climate‐War Nexus Through Bataille's General Economy

Antipode, Volume 58, Issue 2, 2026.
Abstract The spectre of resource scarcity as a cause of war is dominant in discussions about potential links between climate change and armed conflict. Via engagement with Georges Bataille's theory of a general economy of the biosphere, this article conceptualises the relationship between climate change and war by focusing on resource excess as a ...

EDEM-FLUENT coupled simulation of coal-gas outburst two-phase flow

Energy Exploration & Exploitation, 2021
In the process of coal-gas outburst, the gas-solid two-phase flow of pulverized coal and gas will induce large-scale damage to underground mining. In this work, in order to study the dynamic evolution law of gas-solid two-phase flow of coal-gas outburst,

Analysis of a historical accident in a Spanish coal mine [PDF]

, 2019
There has been a long history of coal mine accidents and these, usually, involve serious injuries, fatalities, and the destruction of facilities. In the seventies, an explosion killed 28 miners in a Spanish coal mine.

Coupled Experimental Study and Thermodynamic Modeling of GeO2 and GeO2–CaO and GeO2–SiO2 Binary Systems

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT The phase diagram of the GeO2–CaO system was investigated using differential thermal–thermogravimetric analysis and the equilibration–quenching technique, followed by electron probe microanalysis and X‐ray diffraction. The Ca2Ge7O16 compound was confirmed to be stable, and a eutectic reaction of L → GeO2(hex) + Ca2Ge7O16 was identified in the ...
