Abstract
Chapter 1UV spectrophotometry [24, 25] and voltammetry [26].Both methods cannot distinguish between polysulfide ions of different chain lengths.In this thesis UV spectrophotometry was used for the analysis of polysulfide excess sulfur concentrations.Polysulfide ions are believed to play an important role in biotechnological H 2 S removal processes.First, polysulfide ions are considered to be intermediates in the oxidation of HS -to elemental sulfur, both in the chemical oxidation catalyzed by metal ions and in the biological oxidation by sulfide-oxidizing bacteria [18, 27] (see also section 2.3.3).Furthermore, formation and oxidation of polysulfide ions may affect the rate of H 2 S absorption or the process selectivity for sulfur production.Chapters 3, 4, and 5 of this thesis are particularly concerned with polysulfide chemistry.From pilot plant studies on the removal of H 2 S from pressurized natural gas [28] it was observed that more H 2 S was absorbed in the gas absorber than could be expected Chapter 1 _____________________________________________________________________ 5.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
