Celestite (SrSO4) was selected as the clogging mineral phase for these experiments because of (1) its density is significantly higher than that of sand, making it possible to distinguish it from the quartz in the sand, (2) its rapid precipitation kinetics, and (3) well established knowledge concerning thermodynamic and mineralogic/crystallographic data available.
Chemoinformatics is a well established research field concerned with the discovery of molecule's properties through informational techniques.
Although an overall gender difference in prevalence of major depressive disorder (MDD) has been well established, several questions concerning gender differences in the clinical manifestation of depression remain.

The involvement of MMP-12 in fibrotic processes in the lung is well established, but studies concerning the role of MMP-12 in emphysema are diffuse due to species differences between murine models and humans.
In the literature, the effective macro-scale diffusion coefficients are now well established, while uncertainty remains concerning the relationship between the effective thermodiffusion coefficient and micro-scale parameters (such as pore-scale geometry).
The combinations hypertension-diabetes, hypertension-lipid disorder, hypertension-overweight, hypertension-ischemic heart disease, hypertension-heart failure and diabetes-overweight are quite well covered within disease-specific guidelines because these combinations concern well established comorbid conditions based on causal associations [ 16, 17].
While Miliband was a minister in the last Labour government that approved plans for a third runway, his concerns were well established.
