Controlled Laboratory Experiments on Radon Diffusion Coefficient

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
Radon which occurs inuranium decay series is a noble gas and it moves from the deeper layers of theearth crust to the atmosphere. Formation of the radon gas in the Earth's crustand its migration to atmosphere are quite complex process because of too ...

Moisture Diffusion Coefficient of Concrete under Different Conditions

Buildings, 2023
Humidity change in concrete is the leading cause of concrete shrinkage. Moreover, the moisture diffusion coefficient of concrete is an essential parameter for assessing and predicting the internal moisture content of concrete. However, there is a lack of

Performance of apparent diffusion coefficient values and ratios for the prediction of prostate cancer aggressiveness across different MRI acquisition settings

Diagnostic and Interventional Radiology, 2022
PURPOSE:In this study, we assessed the performance of apparent diffusion coefficient (ADC) and diffusion-weighted imaging (DWI) metrics and their ratios across different magnetic resonance imaging (MRI) acquisition settings, with or without an endorectal

Gas Steady-state Diffusion in Fractal Porous Media [PDF]

E3S Web of Conferences, 2021
Gas diffusion in fractal pores does not follow the classic Fick’s and Knudsen’s laws, so more research on gas diffusion in fractal porous media is needed. Fractal pore models are generated using the random walk method.
