Abstract

fetched live from OpenAlex

The coconut plant is an abundant crop stretching across all regions of Guyana in South America. The coconut coir is a cellulose-rich component of the coconut that can be converted into a versatile, biodegradable plastic film with thermomechanical properties comparable to single-use plastics on the world market. The hemicellulose and lignin content of the coconut coir was reduced by 56.5% and 71.7% respectively. An alkali/bleaching treatment of 8% sodium hydroxide (NaOH) and 8% sodium chlorite (NaClO2) solutions was found to be best. The pretreated coir produced uniform bioplastic films within 6-9 days after dissolution in trifluoroacetic acid (TFA). A 100% conversion of raw coir fibers into plastic film was achieved, with an ultimate tensile strength of 9.12 MPa. This bioplastic film is also thermally stable, starting to degrade at around 250 °C, similar to the degradation temperature of 97% cellulose-rich filter paper.

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.
