H–L<sub>w</sub>–V Equilibrium Measurements of Pure Methane Gas in the Presence of <scp>d</scp>-(+)-Glucose
Bibliographic record
Abstract
The three-phase hydrate–liquid–vapor (H–L w –V) equilibrium conditions of the methane clathrate hydrate in aqueous solutions of d -(+)-glucose were experimentally determined. Equilibrium curves were generated via an isothermal pressure-search method for systems containing (10 to 30) wt % glucose at temperatures between (275.15 and 281.25) K and with pressures ranging from (3.4 to 8.0) MPa. Experimental results show that glucose-containing systems exhibit a considerable inhibiting effect on methane hydrate equilibrium conditions, as the phase equilibria conditions for these systems are shifted to higher pressures than those for pure water systems at a given temperature. It was also found that the degree of inhibition increases in relation to the concentration of the glucose additive and that the inhibition of 30 wt % solutions of glucose is superior to low concentrations of methanol and to equal concentrations of magnesium sulfate.

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.
