Effects of refining steam pressure on the properties of loblolly pine (<i>Pinus taeda</i> L.) fibers
Bibliographic record
Abstract
Abstract Medium density fiberboard is widely used with increasing tendency in North America, particularly in the furniture sector, including door skin and cabinets. Sorption property is one of the most important factors for quality judgment. This study will present water vapor sorption behavior of fibers in the range of varying relative humidity from 11% to 89% as affected by steam pressure of thermomechanical refining in small-scale measurement. A 54-year-old loblolly pine tree was refined at 2 to 18 bar of steam pressure. Fiber properties were determined by scanning electron microscope, dynamic contact angle analyzer, wide angle X-ray diffractometer, and water activity meter. The results showed that steam pressure has a dramatic effect on sorption behavior and surface properties of the refined fiber. In conclusion, a higher rate of sorption was found in juvenile fiber at low steam pressure. Higher water activity and lower crystallinity was found at low steam pressure. The sorption isotherm of refined fiber was fitted very well by the Hailwood-Horrobin model.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
