Onsager reciprocity in premelting solids [PDF]

open access: yes, 2009
The diffusive motion of foreign particles dispersed in a premelting solid is analyzed within the framework of irreversible thermodynamics. We determine the mass diffusion coefficient, thermal diffusion coefficient and Soret coefficient of the particles ...

Controlled Laboratory Experiments on Radon Diffusion Coefficient

open access: yesSakarya 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

open access: yesBuildings, 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

Homogenization results for a linear dynamics in random Glauber type environment [PDF]

open access: yes, 2012
We consider an energy conserving linear dynamics that we perturb by a Glauber dynamics with random site dependent intensity. We prove hydrodynamic limits for this non-reversible system in random media. The diffusion coefficient turns out to depend on the

Negative Correlation between the Diffusion Coefficient and Transcriptional Activity of the Glucocorticoid Receptor [PDF]

open access: yes, 2017
The glucocorticoid receptor (GR) is a transcription factor, which interacts with DNA and other cofactors to regulate gene transcription. Binding to other partners in the cell nucleus alters the diffusion properties of GR.
