Abstract
In the present study three sealed containers (304.8 mm inside diameter and 609.6 mm height) were developed to investigate the concentration of off-gases accumulated in the headspace as well as changes in some of the physical properties of wood pellets during storage. Pellets occupied 75% of the container volume leaving 25% headspace. The outside wall of the steel containers was wrapped with electric heating tapes and fiber glass insulation. The storage studies were carried out at room temperature of about 22 degrees C and at elevated temperatures of 30, 40 and 50 degrees C. The off-gases were collected and analyzed using micro gas chromatography. The accumulations of CO (5000 ppmv) and CO2 (10000 ppmv) were relatively high at room temperature of about 22 degrees C for a storage period of 24 days. These accumulations increased sharply at storage temperatures greather than 30 degrees C. At 50 degrees C, the maximum measured concentration of CO, CO2 and CH4 was about17,000, 70,000 and 3,000 ppmv, respectively. Storage temperature had a significanteffect (PB0.01) on all of the pellet properties, including pellet durability, which dropped by about 20% at the end of 60 days of storage.

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
