Abstract

fetched live from OpenAlex

The comparison of activated carbons of Borassus aethiopum produced in an electric and artisanal furnaces showed similarities and differences in their characteristics. The activated carbon produced in an electric furnace (BA-AC FE) with a specific surface area of 888 m 2 /g is less microporous than the activated carbon produced in an artisanal furnace (BA-AC FA) which has a specific surface area of 1431 m 2 /g. Also, with its BM index (IBM) of 329.5 mg/g the BA-AC FE is more macroporous than the AC-BA-Fa which has an IBM of 28.8 mg/g. This, importance of macroporosity on the AC-BA-FE allowed to obtain an abatement rate of 95.11 % of BM against 72.24 % for the AC-BA Fa. Both carbons have type IV adsorption isotherms. In view of the good characteristics of the BA-AC FA activated carbon, the water issue can be improved in rural areas by building artisanal furnaces. These will allow to produce quality activated carbon and to design carbon filters.

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.
