Experimental study of the influence of the relative humidity of leaves and their link to adhesion losses in the wheel-rail contact

open access: yesMechanics & Industry, 2022
Every autumn, low levels of wheel–rail contact adhesion caused by leaves on the railhead surface are reported by train drivers. These incidents cause problems for the safety and regularity of rail traffic and occur predominantly at the beginning and end ...

Large Variations in the Transpiration of Sorghum Canopies Under High Evaporative Demand Are Positively Related to Water Use Efficiency. [PDF]

open access: yesPlant Cell Environ
ABSTRACT Transpiration restriction under high vapour pressure deficit (VPD), measured indoors with individual plants, increases water use efficiency (WUE). However, VPD is not the only factor driving transpiration, individual plants in a field rapidly become a canopy, and reports on the transpiration restriction versus WUE are scant.

Atmospheric moisture supersaturation in the near-surface atmosphere at Dome C, Antarctic Plateau [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Supersaturation often occurs at the top of the troposphere where cirrus clouds form, but is comparatively unusual near the surface where the air is generally warmer and laden with liquid and/or ice condensation nuclei. One exception is the surface of the
