Abstract

fetched live from OpenAlex

Broreactions of elemental mercury was as a major candidate for near complete depletion of elemental mercury in polar region. The kinetics of the reaction between BrO radicals with gaseous mercury was identified using relative rate method by Gas Chromatography with Mass spectroscopic Detection (GC-MS) at room temperature (298 ± I K) and at atmospheric pressure 760 ± Torr in the N 2 diluent. Propane, DMS and butane were used as reference molecules. The upper and lower limits rate constant for reaction of Hg° with BrO was estimated to be 1.0 × 10 -13 and 1.0 x 10 -15 cm 3 molecules -1 s -1 , respectively. BrO radicals were produced from the photolysis of bromine and dibromomethane in presence of ozone and detected by MS at m / e = 95 or 97. Ozone was produced in a Silent discharged generator. Reaction products were identified using direct mass spectrometer with chemical ionization ion source.

Not 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.
