Abstract
Abstract The photocatalytic reaction for oxidative degradation of a nonionic surfactant, Tween 80 (polyoxyethylene sorbitan monooleate), was examined using TiO 2 photocatalyst powders. An external UV irradiation type slurry bubble column was used as a photoreactor. The rate constant of degradation was proportional to TiO 2 surface area and the square root of UV light intensity and independent on the initial concentration of Tween 80. A simple model for intensity distribution profiles of UV light supplied to the liquid in the photoreactor was developed to use in determining the degradation rate constant. The proposed model could simulate the experimental results satisfactorily.

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 it
