Calculation of the Friction Coefficients of Flax Stems according to their Roughness Characteristics
Published 2019-02-01“…(Conclusions) It has been established that as the humidity of flax stems increases, the molecular component of the friction coefficient increases too. It has been determined that when the moisture content of the stems is 20-45 percent, the friction coefficient values range from 0.38 to 0.98 percent.…”

Relationship between radon and oxygen diffusion coefficients in OPC concretes
Published 2025-08-01“…As concrete often forms the building envelope with the ground, it is interesting to investigate its performance as a barrier, i.e. its radon exhalation, which depends on the radon diffusion coefficient and thickness. Experimentally obtaining the radon diffusion coefficient in concrete is complicated, so it would be useful to be able to use an analytical method for its estimation from parameters that are easier to obtain, such as the oxygen diffusion coefficient, which can be determined experimentally with less difficulty and could even be estimated analytically. …”
