Abstract

fetched live from OpenAlex

The graft copolymer of starch St-g-DAC were synthesized through corn starch(St.) and aacryloxye-thyltrimethyl ammonium chloride(DAC) with potassium peroxydisulfate(KPS) as initiator in water solution.The process was optimized through orthogonal tests,the best reaction condition was that the weigh of initiator was 0.15g,the ratio of St and monomer was 1∶3,the reaction temperature was 55℃,the St-g-DAC was synthesized based on this conditions,its cationic ratio was 48.34%,graft ratio was 82.18%,the DAC had been grafted to starch successfully through its structure which was characterized by Fourier transform infrared spectroscopy(FTIR),and the flocculating properties of starch graft acrylamide(St-g-AM),polyacrylamide(PAM) and St-g-DAC were contrasted through jar test for clay water suspension and sewage.The result shows that St-g-DAC is a better flocculant,it has better flocculating performance than PAM and St-g-PAM for clay water and sewage treatment.

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.
