Air Permeability of the Litter Layer in Broadleaf Forests

Frontiers in Mechanical Engineering, 2019
Fuel on the ground, such as leaves, twigs and decomposing matter, accumulate over time and account for a large percentage of the total fuel load in forests. In fire events, material on the ground is often referred to as a fuel bed.

On the air permeability of Populus pit [PDF]

Computer Methods in Biomechanics and Biomedical Engineering, 2012
Sap hydrodynamics in vascular cells of trees seems to be controlled by small membranes called pits. Understanding how the pit junctions regulate the sap flow and stop embolism by cavitation is today a challenging issue. The hypothesis that the pit porosity adjusts the flow under negative pressure and stops the air bubble diffusion need to be validated.

Air Permeability and Microstructure of a compacted silt treated with different binder dosages [PDF]

E3S Web of Conferences
Treating silt with hydraulic binders induces significant changes in soil microstructure, leading to changes in air permeability. The microstructure changes can be investigated using Mercury Intrusion Porosimeter (MIP), and the air permeability can be ...

On the measurement of air permeability.

Netherlands Journal of Agricultural Science, 1987
Air pemeability values are used to assess the state of aeration, soil structural stability, structural degradation and compaction. A simple experimental procedure, using a constant-speed motor, a syringe and simple pressure sensors, is discussed. At steady-state air flow throught a soil sample the air permeability coefficient can be derived directly ...

Air tightness of compressed air storage energy caverns with polymer sealing layer subjected to various air pressures

Journal of Rock Mechanics and Geotechnical Engineering, 2023
During the operation of compressed air storage energy system, the rapid change of air pressure in a cavern will cause drastic changes in air density and permeability coefficient of sealing layer.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
