Calculation of the Hydrodynamic Permeability of Gels and Gel-Filled Microporous Membranes
Bibliographic record
Abstract
A new approach to the calculation of gel hydrodynamic permeability is presented in which the gel is modeled as an assemblage of spheres whose radius is a function of the gel concentration. Scaling methods coupled with the electrostatic persistence length are used to estimate the correlation length in equivalent semidilute solutions. The correlation length is taken to be equal to the sphere diameter in an assemblage, and the hydrodynamic permeability of the assemblage is calculated using the Brinkman and Happel models. It is shown that the calculated permeabilities are fully in accord with experimental data reported in the literature for membranes with incorporated poly(acrylamide) gels, as well as data reported in this work for membranes containing charged gels composed of poly(4-vinyl- N -benzylpyridinium salts).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
