Abstract
Abstract Sequential inactivation of Cryptosporidium parvum oocysts in modified natural water using ozone followed by free chlorine was studied. Experiments were conducted at 22°C in modified North Saskatchewan River water at pH 8.5 and pH 6. Animal infectivity using neonatal CD-1 mice was used to measure oocyst viability after treatment. The results showed that the overall inactivation of C parvum using ozone followed by free chlorine in modified NSR water was greater at pH 6 compared; to pH 8.5, but that a synergistic effect was observed at pH 8.5 and not at pH 6. The results also indicated that models developed for ozone inactivation in lab water adequately predicted the inactivation of C. parvum in the modified natural water but models developed for free chlorine in lab water did not give an adequate prediction of the free chlorine inactivation. There were no natural water effects on the inactivation of C. parvum when chemical treatment was not applied.

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 it
