Abstract

fetched live from OpenAlex

Eucalyptus urophylla×grandis woodchips stored in different conditions were pulped by using the typical P-RC APMP process. The influences of various storage conditions on its P-RC APMP pulping performance were investigated. A fix pulping conditions such as H2O2 dosage 6.0% and NaOH dosage 4.0% were applied,pulping performance varied with the changing of storage conditions of the Eucalypt chips,the results showed that,at a given Canadian Standard Freeness of 300 mL,comparing to fresh eucalyptus woodchips,3.0% and 12.5% higher refining energies were consumed by woodchips sealed in plastic bags and kept in a cool room and air dried woodchips after one year storage,respectively,and pulp yields decreased by 6.8 and 2.9 points,pulp tensile strengths decreased by 49% and 30%,pulp brightness lost about 5.1 and 5.7 points respectively,and the pollution loads of their pulping effluent were lower than those of fresh wood chips.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
