Abstract

fetched live from OpenAlex

The amount of methane dissolved in the water phase in the presence of CH 4 gas hydrate has been measured at temperatures between 274 and 285 K and pressures ranging from 35 to 65 bar. It was found that the solubility of methane in the presence of hydrate decreases with decreasing temperature in the hydrate formation region. In the absence of gas hydrate the solubility of methane gas in water increases with decreasing temperature as expected. The results show that the hydrate formation process reverses the gas−liquid solubility trend. This confirms theoretical calculations. It was also observed that pressure was not a strong factor on the solubility in the presence of hydrates.

Teacher imitation

Not 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.
