Abstract

fetched live from OpenAlex

Manufacturing of paper produces sludge regard as a good source of carbon and some nutrients for soil can enhance productivity of plants. Incubation experiments were investigated to evaluate the effect of paper sludge resulted by Government paper mill, Basrah province, Iraq on microbial respiration (CO2 evolution) and urease activity as well as soil pH development of two calcareous soils (Al-Zubair and Abul-Khasib). Paper sludge added to soils with the following levels: 0.0,0.5,1.0,1.5,2.0,4.0,6.0,8.0 and 10.0% of the dry soil. Each parameter was assayed at incubation periods of 10, 20 and 30 days. Results showed that CO

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.
