Abstract

fetched live from OpenAlex

The accumulation of non-process elements in the recovery cycle of kraft pulp mills is a current and growing problem. Phosphorus is one of these elements and there is limited information about its behavior in the recovery cycle. Phosphorous reacts with lime, reducing the amount of lime available for recausticizing. The first part of this project, through laboratory work, identified rhenanite (NaCaPO4) as the form of phosphorous in the lime cycle and showed the negative effect of phosphorus on lime availability. Now that rhenanite has been identified, it can be used in future work to build an equilibrium database for equilibrium modeling of phosphorous in the lime cycle. The second part of this project involved field studies and performing a mass balance for phosphorus at a Canadian kraft pulp mill to better understand the flows of phosphorus in the pulp mill and its distribution between the solid and soluble forms.

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.

Full frame distilled prediction

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.
